Description

Technical Field

[0001] The utility model relates to the technical field of graders, in particular to a new fixing structure for wear-resistant plates on the slewing ring of a grader. Background Technique

[0002] The original structure is that the wear-resistant plate is a flat thin plate with two φ15 pin holes. At the same position on the towing frame, there are M14 threaded holes. By making the length of the bolt extend a few millimeters beyond the rear bottom plate of the towing frame, that is, penetrate into the pin hole of the wear-resistant plate. In this way, when the towing frame and the slewing ring rotate relative to each other, the protruding bolt can properly hold the wear-resistant plate and prevent it from moving along.

[0003] Problems of the original structure:

[0004] 1. Difficult assembly (below the installation threaded hole, there is no fixation, and the wear-resistant plate naturally droops, making it difficult to align);

[0005] 2. Part of the bolt penetrates into the wear-resistant plate, and the utilization rate of the wear-resistant plate is extremely low (the thickness of the rear bottom plate of the towing frame is not uniform, and the penetration length of the bolt is not equal, only a few millimeters can be used);

[0006] 3. The area of the bolt blocking the wear-resistant plate is small (when stressed, it is easy to scrape and damage the wear-resistant plate), and the wear-resistant plate naturally droops and is placed on the lower slewing ring. During use, the phenomenon of the slewing ring gnawing on the wear-resistant plate is likely to occur, making the wear-resistant plate more likely to be damaged and fall off, etc.

[0007] Therefore, a new fixing structure for wear-resistant plates on the slewing ring of a grader is proposed. Content of the Utility Model

[0008] The purpose of the utility model is: to solve the problems raised in the above background technique, the utility model provides a new fixing structure for wear-resistant plates on the slewing ring of a grader.

[0009] The utility model specifically adopts the following technical solutions to achieve the above purpose:

The surface of the towing frame bottom plate and the slewing mechanism is provided with a driving mechanism. The top surface of the towing frame bottom plate is provided with multiple groups of positioning and installation holes.

The top surface of the upper wear-resistant plate is fixedly installed with a first bolt column. The top surface of the side wear-resistant plate is fixedly installed with a second bolt column. The upper wear-resistant plate is inserted into the positioning and installation holes on the surface of the towing frame bottom plate through the first bolt column. The side wear-resistant plate is inserted into the positioning and installation holes on the surface of the towing frame bottom plate through the second bolt column. And a bolt is threadedly inserted into the first bolt column and the second bolt column.

[0011] Furthermore, the slewing mechanism includes a slewing ring, a connecting frame is fixedly installed on the surface of the slewing ring, a mounting plate is fixedly installed at the end of the connecting frame, and a flat floor is connected to the surface of the mounting plate through a mounting member.

[0012] Furthermore, the driving mechanism includes a worm gear motor, a worm gear motor is fixedly installed on the top surface of the bottom plate of the traction frame, a gear is fixedly installed at the output end of the worm gear motor, an internal gear ring is fixedly installed on the inner wall of the slewing ring, and the gear and the internal gear ring are meshed and installed.

[0013] Furthermore, after the upper wear-resistant plate is inserted into the positioning and installation hole through the first bolt column on its top surface, the bottom surface of the upper wear-resistant plate is attached to the top surface of the internal gear ring.

[0014] Furthermore, the side wear-resistant plate is arranged in an L-shaped structure, the bottom end of the side wear-resistant plate is located below the internal gear ring, and the edge of the side wear-resistant plate is attached to the inner wall of the slewing mechanism.

[0029] Such as Figures 1 to 6As shown in the figure, a new fixing structure for wear-resistant plates on the slewing ring of a motor grader includes a slewing mechanism 1 and a traction frame bottom plate 3. The end of the slewing mechanism 1 is connected to a flat floor 2. The top surface of the traction frame bottom plate 3 is provided with a traction frame body 4. A driving mechanism 5 is arranged on the surfaces of the traction frame bottom plate 3 and the slewing mechanism 1. The top surface of the traction frame bottom plate 3 is provided with multiple groups of positioning and mounting holes 31. The bottom surface of the traction frame bottom plate 3 is attached with an upper wear-resistant plate 7 and a side wear-resistant plate 8. A first bolt column 71 is fixedly installed on the top surface of the upper wear-resistant plate 7, and a second bolt column 81 is fixedly installed on the top surface of the side wear-resistant plate 8. The upper wear-resistant plate 7 is inserted into the positioning and mounting holes 31 on the surface of the traction frame bottom plate 3 through the first bolt column 71, and the side wear-resistant plate 8 is inserted into the positioning and mounting holes 31 on the surface of the traction frame bottom plate 3 through the second bolt column 81. A bolt 6 is threadedly inserted into the first bolt column 71 and the second bolt column 81. More specifically, the upper wear-resistant plate 7 and the side wear-resistant plate 8 are connected by the bolt 6. The original wire holes above the upper wear-resistant plate 7 and the side wear-resistant plate 8 are changed to the first bolt column 71 and the second bolt column 81 that cooperate with the positioning and mounting holes 31 on the top surface of the traction frame bottom plate 3. Then, the upper wear-resistant plate 7 and the side wear-resistant plate 8 are fixed to the traction frame bottom plate 3 as a whole by the bolt 6. The driving mechanism 5 provides torque input, and the lower slewing mechanism 1 rotates. The traction frame body 4 and the traction frame bottom plate 3 do not move. The slewing mechanism 1 rotates relative to the traction frame bottom plate 3 and the traction frame body 4. The connection between the two is that the upper wear-resistant plate 7 and the side wear-resistant plate 8 rotate relative to each other. At this time, when the traction frame bottom plate 3 and the slewing mechanism 1 rotate relative to each other, it can play a good lubricating and transitional effect.

[0030] The slewing mechanism 1 includes a slewing ring 101. A connecting frame 102 is fixedly installed on the surface of the slewing ring 101. An installation plate 103 is fixedly installed at the end of the connecting frame 102. The flat floor 2 is connected to the surface of the installation plate 103 through a mounting part. More specifically, the flat floor 2 can be fixedly installed by fitting and inserting the installation plate 103 at the end of the connecting frame 102 on the surface of the slewing ring 101.

[0031] The driving mechanism 5 includes a worm gear motor 501. The worm gear motor 501 is fixedly installed on the top surface of the traction frame bottom plate 3. A gear 502 is fixedly installed at the output end of the worm gear motor 501. An internal gear ring 503 is fixedly installed on the inner wall of the slewing ring 101. The gear 502 and the internal gear ring 503 are meshed and installed. More specifically, the worm gear motor 501 drives the gear 502 to rotate. Through the meshing of the gear 502 and the internal gear ring 503, the internal gear ring 503 and the slewing mechanism 1 rotate relative to the traction frame bottom plate 3.

[0032] After the upper wear-resistant plate 7 is inserted into the positioning and mounting holes 31 through the first bolt column 71 on its top surface, the bottom surface of the upper wear-resistant plate 7 is attached to the top surface of the internal gear ring 503. More specifically, by attaching the bottom surface of the upper wear-resistant plate 7 to the top surface of the internal gear ring 503, a lubricating and transitional effect is achieved.

[0033] The side wear-resistant plate 8 is arranged in an L-shaped structure. The bottom end of the side wear-resistant plate 8 is located below the internal gear ring 503, and the edge of the side wear-resistant plate 8 is in fit with the inner wall of the slewing mechanism 1. More specifically, by fitting the side wear-resistant plate 8 with the inner wall of the slewing mechanism 1, the lubrication transition effect is increased.

[0034] When the first bolt column 71 on the top surface of the upper wear-resistant plate 7 and the second bolt column 81 on the top surface of the side wear-resistant plate 8 are inserted into the positioning and mounting holes 31, the top surfaces of the first bolt column 71 and the second bolt column 81 are flush with the top surface of the traction frame bottom plate 3. More specifically, after the first bolt column 71 on the top surface of the upper wear-resistant plate 7 and the second bolt column 81 on the top surface of the side wear-resistant plate 8 are inserted into the positioning and mounting holes 31, the upper wear-resistant plate 7 and the side wear-resistant plate 8 can be fixed more stably through the bolt 6.

[0035] In summary: The upper wear-resistant plate 7 and the side wear-resistant plate 8 are connected by the bolt 6. The original wire holes above the upper wear-resistant plate 7 and the side wear-resistant plate 8 are changed to the first bolt column 71 and the second bolt column 81 that cooperate with the positioning and mounting holes 31 on the top surface of the traction frame bottom plate 3. Then, the upper wear-resistant plate 7 and the side wear-resistant plate 8 are fixed to the traction frame bottom plate 3 as a whole through the bolt 6. The driving mechanism 5 provides torque input, and the lower slewing mechanism 1 rotates. The traction frame body 4 and the traction frame bottom plate 3 do not move. The slewing mechanism 1 rotates relative to the traction frame bottom plate 3 and the traction frame body 4. The connection between the two is through the relative rotation of the upper wear-resistant plate 7 and the side wear-resistant plate 8. At this time, when the traction frame bottom plate 3 and the slewing mechanism 1 rotate relative to each other, a good lubrication transition effect can be achieved.
