The guide shoe comprises a base 16 and a shaft sleeve mounting seat 15, wherein the shaft sleeve mounting seat is centrally arranged above the rear part of the base, a shoe hole 191 horizontally extending front and back is arranged on the shaft sleeve mounting seat, and a guide groove with a downward opening and extending left and right is arranged at the bottom of the base. The guide groove is provided with five inner side surfaces provided with wear-resistant layers, namely a groove front wall surface, a groove rear wall surface, a groove top surface front surface, a groove top surface rear surface and a top surface of a folded edge extending forwards from the lower edge of the groove rear wall. The groove top front surface and the groove top rear surface are two laterally extending strip-shaped surfaces spaced back and forth on the groove top surface. Each wear-resistant layer is divided into two parts which are broken left and right. The front wall and the top of the guide groove are also disconnected to the front part entity of the shaft sleeve mounting seat, the left and right ends of the guide groove close to the middle are respectively provided with a left front step and a right front step, which are collectively called as front steps 11, and the front left and right lower parts of the boot holes on the shaft sleeve mounting seat are respectively provided with a left rear step and a right rear step, which are collectively called as rear steps 12. The left front step, the right front step, the left rear step, and the right rear step each extend from the middle in the left-right direction from the left side or the right side. The bottom surfaces of the left front step and the right front step are flush with the front surface of the groove top surface, the bottom surfaces of the left rear step and the right rear step are flush with the rear surface of the groove top surface, and the wear-resistant layers are arranged. The bottom surfaces of the left front step and the right front step are respectively provided with the same wear-resistant layer with the front surface of the flush groove top surface, namely the 4 th wear-resistant layer 134, and the bottom surfaces of the left rear step and the right rear step are respectively provided with the same wear-resistant layer with the rear surface of the flush groove top surface, namely the 3 rd wear-resistant layer 133. The wear layers provided on the top surface, the groove rear wall surface, and the groove front wall surface of the hem are the 1 st wear layer 131, the 2 nd wear layer 132, and the 5 th wear layer 135, respectively. The setting of preceding step has directly increased the setting space of 4 th, 5 th wearing layer, and the setting space of 2 nd, 3 rd wearing layer has directly been increased to the setting of back step and has indirectly increased the setting space of 1 st wearing layer, makes the length (for example length L1 of 3 rd wearing layer, length L2 of 4 th wearing layer) of each wearing layer obviously increase when comparing no preceding step and back step, consequently the wear resistance of direction boots is showing and is improving, and the life-span is showing and is prolonged, is equivalent to improving single round traveling system's life.
In the embodiment shown in the drawings, the guide shoes are of a bilateral symmetry structure.
The shaft sleeve is provided with an annular outer boss, the guide shoe is in clearance fit with the shaft diameter 511 of the front end part of the shaft sleeve through a shoe hole, and the pressing plate is fixedly installed relative to the shaft sleeve, so that the guide shoe is limited between the pressing plate and the annular outer boss in the front-rear direction. In the embodiment shown in the drawings, the shaft sleeve is fixedly mounted on the housing, and the pressing plate is fixed on the housing from the front of the guide shoe. The output shaft is rotatably supported in the bore of the sleeve by bearings 52. The front end part of the output shaft is suspended outside the shaft sleeve and is coaxially and fixedly connected with the travelling wheel. In the installation state, the travelling wheel is just positioned behind the front step and in front of the rear step, and rotates in a cavity enclosed by the front step and the rear step. There is a gap between the rear face 114 of the front step and the gear teeth, a gap between the front face 124 of the rear step and the gear teeth, and a gap between the rear face 125 of the rear step and the front face 513 of the sleeve.
The guide shoe is in linear sliding connection with the tooth row 31 of the discharging track through the guide groove, a plurality of teeth which are arranged at equal intervals in a linear manner are arranged on the tooth row, and the tooth tips face upwards. The travelling wheel is a toothed wheel, and the travelling wheel is meshed with the tooth row. The travelling wheel rotates under the drive of the output shaft and linearly travels relative to the discharging track. The guiding function of the guide shoe ensures the normal walking of the walking wheel.
The discharging track further comprises a tooth seat 33, and two ends of the joint of two adjacent tooth rows are supported by the same tooth seat in a ground-leaving mode. The front side of the part of the folded edge, which is opposite to the shaft sleeve mounting seat, is provided with a columnar notch 14, and the upper part of the columnar notch is provided with a concave curved surface which inclines towards the front upper side. Most accumulated materials in tooth grooves of the tooth row are extruded downwards by the gear teeth in the walking process, and when the walking wheel walks to the tooth seat, the accumulated materials are not smooth in descending due to the existence of the tooth seat, so that a cleaning channel for the accumulated materials is increased by arranging the columnar gaps, and the discharge of the accumulated materials in the tooth grooves of the tooth seat is improved. The concave curved surface at the upper part of the columnar notch is helpful for guiding materials to enter the columnar notch and leak downwards.
The tooth row also comprises a front vertical wall and a rear vertical wall, the teeth on the tooth row are positioned between the front vertical wall and the rear vertical wall and are fixedly connected with the front vertical wall and the rear vertical wall, the lower parts of the end parts of the two front vertical walls at the joint of the two adjacent tooth rows are embedded into a through groove which is positioned in the same tooth seat and is open above the rear part of the tooth seat, and the lower parts are fixedly connected with the tooth seat through pins 32.
The surface of the guide groove, which is contacted with the wear-resistant layer when the guide groove is in linear sliding connection with the tooth row, comprises the front side surface of the front vertical wall, the top plane of the rear vertical wall, the rear side surface of the rear vertical wall and the bottom plane of the rear vertical wall.
The middle part and the left and right ends of the top rear edge of the tooth holder are respectively provided with a middle discharge chute 331 and an end discharge chute 332, and the middle discharge chute and the end discharge chute are concave curved surfaces which incline towards the rear upper side. The columnar notch, the middle discharge chute and the end discharge chute provide discharge channels for the gear rows. The travelling wheels can clean accumulated materials outwards from tooth grooves while travelling, and particularly when the accumulated materials pass through tooth seats, the accumulated materials are cleaned more smoothly after the structure of each discharging channel is arranged, and the service life of the single-wheel travelling system is prolonged on the other hand.
The profile of the gear teeth of the travelling wheel in both axial and radial directions is preferably in the shape of an elongated pointed dome with a wide tooth root and a narrow tooth top. Such as the circular arc top 21 on the radial section and the upper side 23 and the lower side 22 on the axial section, the formed pointed head is easier to squeeze and discharge materials, thereby being beneficial to further improving the cleaning of accumulated materials in tooth grooves at tooth seats. The axial width of the tooth is 15-25mm narrower than the distance between the front and rear vertical walls at the corresponding position, the axial width of the tooth top is 35-45mm narrower than the distance between the front and rear vertical walls at the corresponding position, the tooth center is positioned between the front and rear vertical walls, and the front and rear side surfaces of the tooth root are respectively in transition with the end surfaces of the corresponding sides of the wheel hub by large fillets 24, so that the tooth top has enough strength in the axial direction.
The top surfaces of the two parts on the base, which are positioned on the left side and the right side of the shaft sleeve mounting seat, are boot inclined surfaces 194 with high middle and low two ends, the bottom surfaces of the left part and the right part of the pressing plate are plate inclined surfaces 62 with high middle and low two ends, and in the mounting state, the boot inclined surfaces are in clearance fit with the plate inclined surfaces, so that the guide boot can circumferentially rotate in a small range. At the same time, there is a gap between the rear end face 192 of the guide shoe and the front end face 512 of the annular outer boss, and there is a gap between the front end face 193 of the sleeve mount of the guide shoe and the rear plate face 61 of the platen 6, so that the guide shoe can move axially in a small range. Therefore, the guide shoe can automatically fine-tune the pose in the sliding process.
The wear-resistant layer is preferably formed by build-up welding in a partial groove 102 of the smooth surface of the corresponding blank surface 101 of the guide groove after said groove has been machined. The steps 103 on the surface of the blank are reserved between two adjacent mutually perpendicular partial grooves, round corners are formed on the bottom edges of the step surfaces and the partial grooves, the former is a blank big round corner 1011 for reducing stress concentration during blank forming, and the latter is a machining round corner 1021 for facilitating combination of a wear-resistant layer and a matrix and transition between the wear-resistant layers. The preparation of the relevant surface before build-up ensures the production reliability of the wear layer.
The lengths of the bottom surfaces of the left rear step and the right rear step in the left-right direction are preferably 0.3-0.8 times of the lengths of the rear surfaces of the top surfaces of the corresponding end grooves, so that the possible setting lengths of the 1 st, 2 nd and 3 rd wear-resistant layers can be 1.5 times of the lengths of the wear-resistant layers of the common guide shoes, and the ultra-long wear-resistant layers are realized.
The right sides of the left front step and the left rear step are respectively provided with a left-lower right-upper inclined side guide surface, and the left sides of the right front step and the right rear step are respectively provided with a left-upper right-lower inclined side guide surface. The wear layers 131, 132, 133, 134, 135 enclose a guide frame opening, and the front step side guide surface 112 on the front step and the rear step side guide surface 122 on the rear step provide a guide for the rows of teeth to enter the guide frame opening. The rear step is further provided with an arc-shaped surface 123 connected with the side guide surface 122, and the arc-shaped surface and the corresponding side guide surface enclose a sharp corner structure. When the gear teeth rotate in the tooth grooves filled with the materials and drive the materials to roll upwards to the upper parts of the guide grooves, the arc-shaped surfaces play a role in guiding, and a guide channel is provided for the falling back of the mineral aggregate upwards from the travelling wheel belt.
The surface of the wear layer provided on the front wall of the groove is preferably a front bevel 1351 inclined toward the rear lower side, preferably at an angle of 2-4 °, and the upper half of the surface of the wear layer provided on the rear wall of the groove is preferably a rear bevel 1321 inclined toward the front lower side, preferably at an angle of 2-3 °. The front inclined plane and the rear inclined plane are used for matching with the casting bevel structure characteristics on the tooth row, so that overlarge gaps between the wear-resistant layers on the front wall surface and the rear wall surface of the groove and corresponding matching surfaces on the tooth row are avoided, and the matching effect between the guide groove and the tooth row is improved. The 5 th wear layer 135 has an upper chamfer 1352 of about 1mm at the end face interface, and lower chamfer 1311, upper chamfer 1352, rear chamfer 1321, front chamfer 1351 provide assurance to proper wear layer contact with the row of teeth.
According to the invention, the front step and the rear step are arranged on the guide shoe, so that the arrangement space of each wear-resistant layer is increased, the length of the wear-resistant layer can be about 1.5 times of the length of the wear-resistant layer on the common guide shoe, and the wear-resistant effect is obviously improved, thereby greatly prolonging the service life of the single-wheel travelling system of the mining machine.
