[0002] Wear-resistant pipe transportation is widely used in electricity, metallurgy, coal, petroleum, chemical industry, building materials, machinery and other industries, and is developing at a high speed. At the same time, the wear of wear-resistant pipes is also a common phenomenon. With the widespread application of wear-resistant pipes, the requirements for the processing technology of wear-resistant pipes are gradually becoming stricter.

[0003] During the production and processing of wear-resistant pipes, they will go through multiple processes, such as grinding. In these processes, the pipes need to be rotated to improve the production quality of the pipes.

In addition, due to the special shape of the pipe, it will slip during rotation, thus affecting the final wear-resistant pipe processing. For this reason, we propose a rotation auxiliary device for wear-resistant pipe processing to solve the above problems. Utility Model Content

[0025] Reference Figure 1-Figure 7A rotation auxiliary device for wear-resistant pipe processing includes a base 1, a mounting plate 4 is connected to the base 1 through a support rod 3, the mounting plate 4 is rotatably connected to the support rod 3, and a driving mechanism for controlling the rotation of the mounting plate 4 is also provided on the support rod 3 to drive the mounting plate 4 to rotate, thereby facilitating the rotation auxiliary operation of the wear-resistant pipe processing. A scissor support bracket 2 is also provided on the base 1, and the position of the scissor support bracket 2 and the mounting plate 4 are correspondingly arranged. The structure of the scissor support bracket 2 is as follows: Figure 1 As shown, the structure is a prior art, which is used to support the wear-resistant pipe, and the support height can be adjusted according to the position of the fixing mechanism. A fixing mechanism is provided on the side of the mounting plate 4 close to the scissor support bracket 2. When one end of the wear-resistant pipe is fixed by the fixing mechanism, the other end of the wear-resistant pipe is supported on the scissor support bracket 2. Therefore, when the driving mechanism drives the fixing mechanism to rotate, the wear-resistant pipe can be driven to rotate, thereby providing auxiliary support for the rotation processing of the wear-resistant pipe.

[0026] The fixing mechanism includes an inner clamping mechanism and an outer clamping mechanism, and the inner clamping mechanism and the outer clamping mechanism are arranged parallel to each other, the inner clamping mechanism includes an inner splint 1 5 and an inner splint 2 7 which are arranged correspondingly up and down, and the outer clamping mechanism also includes an outer splint 1 6 and an outer splint 2 8 which are arranged correspondingly up and down, the inner splint 1 5 and the inner splint 2 7 as well as the outer splint 1 6 and the outer splint 2 8 are all triangles corresponding to each other up and down, and the inner splint 1 5 and the inner splint 2 7 as well as the outer splint 1 6 and the outer splint 2 8 can be spliced ​​into a rhombus, the inner splint 1 5 and the inner splint 2 7 as well as the outer splint 1 6 and the outer splint 2 8 are connected by two identical springs 10, and the initial state of the springs is in a stretched state, the inner splint 1 5 and the inner splint 2 7 as well as the outer splint 1 6 and the outer splint 2 8 are all connected by two identical springs 10, and the initial state of the springs is in a stretched state, the inner splint 1 5 and the inner splint 2 The outer splint 1 6 and the inner splint 2 7 and the outer splint 2 8 are connected by a telescopic rod 17, the inner splint 1 5 and the outer splint 2 8 as well as the inner splint 2 7 and the outer splint 1 6 are connected by a scissor rod 11, and the scissor rod 11 is symmetrically arranged. The side wall of the mounting plate 4 is provided with two symmetrically arranged vertical sliding openings 12, and the side wall of the inner splint 1 5 is symmetrically fixed with sliding rods 13 matching the sliding openings 12. The inner splint 1 5 and the mounting plate 4 are slidingly connected by the sliding openings 12 and the sliding rods 13, and the inner splint 2 7 and the mounting plate 4 are fixedly connected. The mounting plate 4 is also provided with a clamping mechanism for controlling the inner splint 1 5, which is used to automatically complete the clamping operation of the wear-resistant pipe, which is very convenient.

[0027] The engaging mechanism is symmetrically arranged on both sides of the mounting plate and the slide plate, and the engaging mechanism includes a block 20 and a protrusion 21 that matches with the mounting plate 4. A slide groove 18 is also provided on the mounting plate 4, and a slide plate 9 is slidably connected in the slide groove 18 through a plurality of springs 19. The size of the slide plate 9 matches the slide groove 18. The block 20 is fixedly connected to the slide plate 9, and the protrusion 21 is fixedly connected to the inner clamping plate 5. Figure 4When the slide plate 9 drives the block 20 to move downward, the block 20 and the protrusion 21 can be automatically released from the engagement because the spring 10 is in a stretched state when engaged.

[0028] A clamping mechanism is also provided between the outer clamping plate 1 6 and the outer clamping plate 2 8. The clamping mechanism includes a ratchet bar 14 fixedly arranged on the side wall of the outer clamping plate 1 6 and a ratchet 22 arranged on the side wall of the outer clamping plate 2 8. A fixing frame 15 is provided on the side wall of the outer clamping plate 2 8. The ratchet 22 is rotatably arranged in the fixing frame 15 through a one-way bearing. An unlocking mechanism is also provided on the fixing frame 15, which can strengthen the clamping effect of the fixing mechanism on the wear-resistant pipe, so that it is not easy to slip during rotation.

[0029] The unlocking mechanism includes a rotating shaft 23 and a rotating knob 26 which is slidably connected to the rotating shaft 23, and the rotating knob 26 does not rotate with the rotating shaft 23. The ratchet 22 is fixedly connected to the rotating shaft 23. A fixing ring 24 is sleeved on the rotating shaft 23, and a one-way bearing is located between the fixing ring 24 and the rotating shaft 23. The rotating knob 26 and the fixing ring 24 are connected by a spring 27. A clamping rod 28 is provided on the side wall of the rotating knob 26. A clamping ring 25 is provided at the connection between the rotating shaft 23 and the fixed frame 15, and a notch matching the clamping rod 28 is provided on the clamping ring 25.

[0031] In the present invention, when it is necessary to fix and rotate the wear-resistant tube, refer to the attached Figure 2 and 3 , insert the wear-resistant tube into the fixing mechanism, when the wear-resistant tube abuts against the slide plate 9 and squeezes the slide plate 9, the slide plate 9 moves toward the mounting plate 4 and compresses the spring 2 19, refer to the attached Figure 4 When the clamping block 20 follows the sliding plate 9 to slide, the clamping block 20 and the protrusion 21 are released. Under the action of the spring 10, the inner clamping plate 15 slides downward through the cooperation of the sliding port 12 and the sliding rod 13, and cooperates with the inner clamping plate 27 to complete the pre-fixation of the wear-resistant pipe. At the same time, the outer clamping plate 16 and the outer clamping plate 28 are moved closer to each other to complete the clamping under the action of the telescopic rod 17 and the scissor rod 11, and move to the side away from the mounting plate 4. Therefore, the fixing mechanism can automatically complete the fixing and clamping function when the wear-resistant pipe is inserted, and can play an auxiliary role in the rotation processing of the wear-resistant pipe under the cooperation of the driving mechanism and the scissor support 2.

[0032] See attached Figure 2 As shown, a clamping mechanism is also provided between the outer clamping plate 1 6 and the outer clamping plate 2 8. The clamping mechanism of this scheme adopts a ratchet mechanical structure. When the outer clamping plate 1 6 moves downward, the ratchet bar 14 moves downward. Figure 5 In this perspective, the ratchet bar 14 moves to the right but cannot move to the left. Therefore, when the external extrusion force is applied, the fixing mechanism in the present application can strengthen the clamping of the wear-resistant pipe to avoid slipping during auxiliary rotation. When the material needs to be replaced, refer to the attached Figure 5 From the perspective of the embodiment of the present invention, the knob 26 is rotated counterclockwise, thereby driving the ratchet 22 to rotate counterclockwise through the rotating shaft 23, so that the ratchet 22 is separated from the ratchet bar 14, thereby releasing the engagement. Figure 5 and attached Figure 6 When the knob 26 is rotated counterclockwise, the clamping rod 28 is driven to rotate to the notch on the clamping ring 25. Under the action of the spring three 27, the clamping rod 28 is stuck in the notch, so that the ratchet 22 is separated from the ratchet bar 14 for a long time, so that it is convenient for the staff to replace the material.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
