Abstract
The invention discloses a hopper bearing device of a road surface paver, belonging to the engineering machinery. The device comprises two sets of symmetrical supporting frames respectively arranged at the lower parts of a left hopper and a right hopper of the paver; each supporting frames comprises a hopper holding plate, a frame bearing plate, a frame fixing plate, a track bearing plate and a track fixing plate; the shape and the size of the hopper holding plate are matched with that of a hopper bottom plate of the paver; when the hopper of the paver is fully unfolded, the hopper bottom plate clings to the hopper holding plate; the frame fixing plate is fixed at the outer side of a frame beam; the upper end of the frame bearing plate is connected with the hopper holding plate while the lower end thereof is overlapped at the upper end of the frame bearing plate; the track fixing plate is fixed at the outer side of a track beam; and the upper end of the track bearing plate is connected with the hopper holding plate while the lower end thereof is fixed at the outer side of the track fixing plate through a bolt. The invention has the positive effects of: decomposing the impact force suffered by the hopper onto the frame so as to ensure that the stress of the hopper is rational and the service life of the hopper is prolonged, and ensuring that the mounting and the dismounting are convenient.
Description
Technical field
The present invention relates to a kind of engineering machinery, be specifically related to a kind of sub-base grader hopper supporting arrangement.
Technical background
Sub-base grader is the most frequently used machinery of paving the way, and about the hopper of paver has two, rotates by the Driven by Hydraulic Cylinder hopper.By tipping lorry discharging in hopper, very big to the impact force of hopper, cause the hopper distortion easily, hopper is scrapped when serious.The hopper method for supporting of existing sub-base grader is to install rubber cushion blocks additional on the frame beam, and when left and right sides hopper was in maximum opening, the front portion of left and right sides hopper contacted with left and right sides rubber cushion blocks.This method plays certain effect, but because rubber cushion blocks is limited with the area on frame, so just limited the lifting surface area of left and right sides hopper and rubber cushion blocks, just increased the bearing pressure on the unit area of hopper thus, and just caused rubber cushion blocks aging easily because the material factor of rubber itself is added the factor of the site environment that paves, caused the rubber cushion blocks replacement cycle frequent.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of sub-base grader hopper supporting arrangement, select piece installing as paver a kind of, increased the lifting surface area of hopper, alleviated the bearing pressure on the unit area of hopper; Alleviated moment when hopper is let out thing to the surge of hopper, prevent the distortion of hopper.Simultaneously hopper oil cylinder overload hidden danger has been played very big effect.
The present invention realizes with following technical scheme: a kind of sub-base grader hopper supporting arrangement, and this device is made up of the identical two groups of bracing frames of shape and size, and two groups of bracing frames are installed in the bottom of paver left and right sides hopper symmetrically; Described bracing frame comprises: hopper supporting plate, rack support plate, frame fixed head, crawler belt base plate and crawler belt fixed head; Described hopper supporting plate shape and size match with the hopper of paver base plate, and when hopper of paver was opened fully, the hopper base plate was close on the hopper supporting plate; Described frame fixed head is fixed on the outside of frame beam, and described rack support plate upper end is connected with the hopper supporting plate, and the lower end of rack support plate is overlapped on the upper end of rack support plate; Described crawler belt fixed head is fixed on the outside of crawler belt beam, and described crawler belt base plate upper end is connected with the hopper supporting plate, and the lower end of crawler belt base plate is by being bolted to the outside of crawler belt fixed head.
Good effect of the present invention is:
1, the impact force that hopper is subjected to decomposes on the frame, and two gussets have decomposed the shearing force of bolt, makes hopper stressed reasonable, avoids blastic deformation, improves the application life of hopper.
2, compact conformation, with low cost, be convenient to promote the use of.
3, installation, convenient disassembly fix upper support shelf by four bolts.

Fig. 3 is the left view of Fig. 1.
Among the figure: 1, frame fixed head, 2, the rack support plate, 2-1, fixed block, 3, the crawler belt beam, 4, the hopper supporting plate, 5, the crawler belt base plate, 6, gusset, 7, bolt, 8, the frame beam, 9, the crawler belt fixed head.
The specific embodiment
As shown in Figure 1, 2, 3: sub-base grader hopper supporting arrangement is made up of two groups of symmetrical, identical bracing frames of shape and size, is installed in the bottom of paver left and right sides hopper respectively.Bracing frame comprises: hopper supporting plate 4, rack support plate 2, frame fixed head 1, crawler belt base plate 5 and crawler belt fixed head 9; Hopper supporting plate 4 shape and size match with the hopper of paver base plate, and when hopper of paver was opened fully, the hopper base plate was close on the hopper supporting plate 4; Increase the lifting surface area of hopper, alleviated the bearing pressure on the unit area of hopper, alleviated the surge of moment hopper, prevented hopper oil cylinder overload impact pulling force.Described frame fixed head 1 is fixed on the outside of frame beam 8, and described rack support plate 2 upper ends are connected with hopper supporting plate 4, and the lower end of rack support plate 2 is overlapped on the upper end of rack support plate 2; Described crawler belt fixed head 9 is fixed on the outside of crawler belt beam 3, and described crawler belt base plate 5 upper ends are connected with hopper supporting plate 4, and the lower end of crawler belt base plate 5 is fixed on the outside of crawler belt fixed head 9 by bolt 7.Connect by four bolts 7, dismantle more convenient.
The arranged outside fixed block 2-1 of described rack support plate 2 lower ends, the upper end of described frame fixed head 1 makes step groove, and the lower end of described fixed block 2-1 is installed in the described step groove.
Described crawler belt base plate 5 inboard fixedly gussets 6, described gusset 6 is many, the lower end of gusset 6 is overlapped on the upper end of crawler belt fixed head 9.Gusset is supported on the crawler belt beam, purpose be the most pressure distribution on the hopper on the frame and on the crawler belt beam, destroyed to prevent four bolts 7 to be subjected to shearing force.
