In the present embodiment, the deburring swing arm body 4 includes a swing arm 40 and a deburring head 45. One end (41) of the swing arm 40 is rotatably sleeved on the second connecting support 54, and the other end (42) is provided with the chisel hair head 45. The second connecting strut 54 not only serves as a connecting part between the tool holder upper support plate 52 and the tool holder lower support plate 51 to provide connecting support for the two support plates, but also serves as a pivot shaft of the roughening swing arm body 4 to provide rotary support for centrifugal swing of the roughening swing arm body 4, so that structural strength reduction caused by additional holes formed in the tool holder upper support plate 52 and the tool holder lower support plate 51 due to additional pivot shafts added between the tool holder upper support plate 52 and the tool holder lower support plate 51 is avoided, and structural integration can be improved.
A plurality of scabbling protrusions are distributed on the scabbling head 45. The roughening bulge is in a conical structure. Preferably, the roughening head 45 has a rigid structure so as to have sufficient strength for roughening. A plurality of loops of roughening projections are evenly arranged on the side wall of the roughening head 45. The roughening projection swivels outwardly about the second connecting strut 54 when the roughening blade holder 5 is rotated.
The chisel edge tool holder 5 is also provided with a biasing elastic member. The biasing elastic member is used to apply a biasing force to the chisel arm body 4 to rotate it inward. A first limit column 55 is also arranged between the tool rest lower support plate 51 and the tool rest upper support plate 52. The first restraint post 55 is located radially outwardly of the offset second connector strut 54. The outer diameter of the first limit column 55 is larger than the outer diameter of the second connecting strut 54. The first limit post 55 is located on the other side of the second connecting strut 54 with respect to the burr head 45. The first stopper post 55 is provided to limit the outermost position of the clamping head 42.
This centrifugation swing arm formula railway box girder anchor cave chisel hair ware's chisel hair swing arm body 4 forms the flail knife structure when rotatory, and rotatory in-process chisel hair head 45 receives rotatory centrifugal force and opens to still receive bellied reaction force on anchor cave wall or the wall at the chisel hair in-process, make its rotatory in-process form the scraping chisel hair, further still can form intermittent centrifugal swing, the formation of the chisel hair of changing promotes the hair wall and generates efficiency.
In fig. 3, the roughening head 45 is oriented clockwise, and the direction of rotation of the roughening blade holder 5 is opposite to the orientation of the roughening head 45. The axial length of the burr 45 is smaller than the axial interval between the tool holder upper support plate 52 and the tool holder lower support plate 51, and a part of the burr 45 can be accommodated between the tool holder upper support plate 52 and the tool holder lower support plate 51 at the initial position, so that the interference of the reset of the whole burr swinging arm body 4 is avoided.
Specifically, the first connecting strut 53 is a steel bar, and connects the tool holder connecting plate 50 and the tool holder lower support plate 51 by threads at both ends thereof. The tool holder lower bracket plate 51 is a steel plate with a plurality of bolt holes. The second connecting strut 54 is a steel rod, and connects the tool holder lower support plate 51 and the tool holder upper support plate 52 by means of threads at both ends thereof.
The biasing resilient member includes a torsion spring 48 sleeved outside the second connecting strut 54. One end of the torsion spring 48 is limited by the first limit column 55, and the other end of the torsion spring is limited by the swing arm 40, so that a biasing force for enabling the swing arm 40 to rotate inwards is applied to the swing arm; the outer side wall surface of the swing arm 40 has a limiting surface for contacting and limiting the first limiting column 55. The limiting surface can be a single plane or a folded surface formed by two adjacent planes.
The first stopper column 55 restricts the maximum swing width (angle) of the chisel arm 4 from being lower than 90 degrees, so as to prevent the chisel arm 4 from being difficult to return due to excessive swing during chisel, and further, the maximum swing width (angle) of the chisel arm 4 is lower than 75 degrees. When the chisel edge swing arm 4 contacts the first position-limiting column 55 (at the outermost position) for limiting, the chisel edge swing arm 4 is still located on the counterclockwise side of the second connecting support 54 (or the straight line passing through the diameter of the second connecting support 54), and the outermost position and the innermost position of the chisel edge swing arm 4 are both located on the same side of the second connecting support 54.
Further, the position of the first stopper column 55 is adjustable to change the outermost position of the burring swing arm body 4, that is, to change the maximum swing amplitude position of the burring swing arm body 4. The two ends of the first limit column 55 can respectively extend out of the tool rest upper support plate 52 and the tool rest lower support plate 51 and are connected through nuts, so that the first limit column 55 is fixedly pressed on the tool rest upper support plate 52 and the tool rest lower support plate 51 to realize positioning, the tool rest upper support plate 52 and the tool rest lower support plate 51 are provided with opposite slotted holes with the same shape or are provided with a plurality of opposite and dispersed connecting holes, the first limit column 55 is positioned at different positions of the slotted holes or is connected to the connecting holes at different positions to realize the position adjustment of the first limit column 55, and therefore the chiseling swing arm body 4 can be used for chiseling and polishing any concrete surface within the range limited by the first limit column 55.
The lower support plate 51 of the tool holder is a circular ring plate. The holder plate 52 is an annular plate, and the outer edge of the holder plate 52 has a plurality of receiving grooves 521 arranged in the circumferential direction. The shape of the receiving groove 521 substantially matches the shape of the upper clamping plate 421. The plurality of accommodation grooves 521 are evenly arranged in the circumferential direction.
The swing arm 40 has a connecting plate end 41 connected to a second connecting strut 54, and a clamping head end 42 connected to the burr head 45. The connecting plate end 41 is sleeved on the tool holder lower support plate 51 and the tool holder upper support plate 52, and the torsion spring 48 is sleeved outside the second connecting support 54 and below the connecting plate end 41. The gripper head end 42 has axially opposed upper and lower gripper plates 421, 422. The weight of the clamping head end 42 is greater than the weight of the web end 41 to better throw out for chiseling. The burr-cutting head 45 is rotatably sandwiched between an upper holding plate 421 and a lower holding plate 422. The upper clamping plate 421 has the same height as the tool holder upper support plate 52 with respect to the tool holder lower support plate 51. In the rest state, the torsion spring 48 allows the gripper head end 42 to be received in the receiving groove 521.
A second limit column 56 is arranged between the tool rest lower support plate 51 and the tool rest upper support plate 52. The second restraint post 56 is located on the inner side of the swing arm 40. The second connecting strut 54 is screwed with the first and second limit posts 55 and 56 to the tool holder lower bracket plate 51 and the tool holder upper bracket plate 52. When the swing arm 40 is in contact with the second limiting column 56 for limiting, the clamping head end 42 is accommodated in the accommodating groove 521, and the upper clamping plate 421 is not in contact with the bottom wall of the accommodating groove 521. The inner and outer spacing is performed by the first spacing post 55 and the second spacing post 56.
Of course, the first restraint post 55 can also restrain the innermost position of the clamping head 42 in one possible embodiment. When the swing arm 40 rotates inward, the part of the connecting plate end 41 on the side of the second connecting strut 54 away from the chisel head 45 forms a contact limit with the first limit column 55. And when the clamping head end 42 is positioned at the outermost position, the part of the swing arm 40 positioned on the same side of the burr drilling head 45 and the first limiting column 55 form a contact limiting position.
The centrifugal swing arm type railway box girder anchor recess chiseling device further comprises a dust cover 3. The dust cover 3 covers the tool rest connecting plate 50 and the upper connecting plate 13, and is fixedly connected with the upper connecting plate 13. The dust cover 3 is made of rubber and is provided with a connecting hole for externally connecting a dust collector.
In a feasible embodiment, the roughening knife rest 5 is eccentrically arranged on the output shaft of the hydraulic motor 2 to form an eccentric wheel or cam-like structure, so that the roughening swing arm body 4 is not only provided with rotary power when rotating, but also the roughening knife rest 5 is eccentrically rotated, so that the roughening swing arm body 4 on the roughening knife rest is subjected to constantly changing centrifugal force, and variable alternating load is provided in the roughening process, and the roughening efficiency is improved.
When the centrifugal swing arm type railway box girder anchor recess chiseling device is used, the centrifugal swing arm type railway box girder anchor recess chiseling device is externally connected with a mechanical arm and a dust collector, and the machine is started. The centrifugal swing arm type railway box girder anchor recess chiseling device is stretched into the anchor recess through an external mechanical arm. And the scabbling head 45 of the scabbling swing arm body 4 impacts the concrete surface of the anchor recess at a high speed to realize scabbling. At the moment, the hydraulic motor 2 drives the chiseling tool rest 5 to rotate rapidly, the chiseling swing arm body 4 is thrown out due to the fact that the centrifugal force is larger than the biasing force of the torsion spring 48, the chiseling head 45 is driven to impact the concrete surface in the anchor recess at a high speed, and the purpose of chiseling is achieved. And finally, driving the chiseling device to slowly move towards the outside of the anchor recess through the mechanical arm, and achieving chiseling of the whole range of the anchor recess.
And as for the position of the roughening swing arm 40, the range thrown out by the roughening swing arm body 4 in the high-speed rotation process of the roughening tool rest 5 is limited by the first limiting column 55, only a certain range can be reached, and the roughening swing arm body 4 can roughen and polish any concrete surface within the range limited by the first limiting column 55 and the second limiting column 56. After the hydraulic motor 2 is stopped, the centrifugal force disappears, and the hydraulic motor is retracted into the roughening cutter holder 5 by the pressure of the torsion spring 48.

For values less than 1, one unit is suitably considered to be 0.0001, 0.001, 0.01, 0.1. These are only examples of what is intended to be explicitly recited, and all possible combinations of numerical values between the lowest value and the highest value that are explicitly recited in the specification in a similar manner are to be considered.
Unless otherwise indicated, all ranges include the endpoints and all numbers between the endpoints. The use of "about" or "approximately" with a range applies to both endpoints of the range. Thus, "about 20 to about 30" is intended to cover "about 20 to about 30", including at least the endpoints specified.
All articles and references disclosed, including patent applications and publications, are hereby incorporated by reference for all purposes. The term "consisting essentially of …" describing a combination shall include the identified element, ingredient, component or step as well as other elements, ingredients, components or steps that do not materially affect the basic novel characteristics of the combination.
