Description

Technical Field

[0001] The utility model relates to a PVC pipe pulling machine, belonging to the technical field of PVC pipe production. Background Art

[0002] The PVC pipe traction machine is mainly used to traction and convey the finished PVC pipes.

[0003] The tractor generally uses two upper and lower crawlers to fix the PVC pipe, thereby pulling the PVC pipe forward. However, there is a lack of additional support structure for the PVC pipe between the upper and lower crawlers of the tractor, which will cause the PVC pipe to deviate from the tractor when being pulled.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a PVC pipe traction machine, which solves the problem in the prior art that there is a lack of additional supporting structure for the PVC pipe between the upper and lower crawlers of the traction machine, which may cause the PVC pipe to deviate from the traction machine when being towed.

[0006] The technical problem to be solved by the utility model is achieved by adopting the following technical scheme: comprising a working platform and a traction crawler assembly arranged above the working platform and used for traction of PVC pipes, and also comprising:

[0007] Two fixing plates, both of which are arranged on the working platform and are respectively located at one end of the traction crawler assembly close to the conveying direction of the PVC pipe.

[0008] Two arc clamping blocks, two arc clamping blocks are used to clamp the PVC pipe,

[0009] The two arc-shaped clamping blocks are relatively slidably arranged between the two fixing plates, and a driving mechanism for driving the arc-shaped clamping blocks is also arranged between the two fixing plates.

[0010] By adopting the above technical solution, when the traction track assembly tows the PVC pipe, the driving mechanism is started to make the two arc-shaped clamping blocks slide in opposite directions until the inner walls of the two arc-shaped clamping blocks abut against the outer wall of the PVC pipe, so that the two arc-shaped clamping blocks provide guiding support for the traction of the PVC pipe, thereby preventing the PVC pipe from deviating from the traction machine when being towed.

[0011] The utility model is further configured as follows: the driving mechanism includes two mounting plates and a double-headed screw:

[0012] The double-headed screw is rotatably connected between the two fixed plates, the threads at both ends of the double-headed screw are in opposite rotation directions, the two mounting plates are respectively threadedly connected to the two ends of the double-headed screw, and the two mounting plates are respectively fixedly connected to the outer side walls of the two arc-shaped clamping blocks.

[0013] By adopting the above technical solution, the double-headed screw is driven to rotate, so that the mounting plates located at both ends of the double-headed screw can slide towards each other, and then the mounting plates can drive the arc-shaped clamping blocks to slide towards each other to clamp the PVC pipe.

[0014] The utility model is further configured as follows: one end of the double-headed screw rod extends to the outside of the fixed plate and is provided with a rotating disk.

[0015] By adopting the above technical solution, the double-headed screw can be driven to rotate by rotating the turntable. The turntable is provided, and the force points for rotating the double-headed screw are increased, making the rotation of the double-headed screw more labor-saving.

[0016] The utility model is further configured as follows: a plurality of guide wheels are rotatably arranged on the inner walls opposite to each other of the two arc-shaped clamping blocks, and the rotation radial direction of the guide wheels faces the conveying direction of the PVC pipe.

[0017] By adopting the above technical solution, when the arc-shaped clamping block approaches the PVC pipe, the PVC pipe will abut against the outer wall of the guide wheel. When the PVC pipe moves, the guide wheel will rotate. The rotation of the guide wheel will convert the sliding friction between the PVC pipe and the arc-shaped clamping block into rolling friction, thereby reducing the resistance between the two, thereby making the transportation of the PVC pipe smoother.

[0018] The utility model is further configured as follows: two guide plates are arranged on the upper end surface of the working platform, two fixing plates are respectively inserted into the two guide plates, the fixing plates slide in the guide plates along the vertical direction, and a limiting piece for limiting the sliding of the fixing plates is also arranged on the guide plates.

[0019] By adopting the above technical solution, when the height of the arc clamping block cannot be aligned with the traction height of the PVC pipe, first release the limit of the fixed plate by the limit member, then pull the fixed plate to make the fixed plate slide in the guide plate to the actual required height, and finally reuse the limit member to fix the fixed plate and the guide plate together, thereby ensuring that the clamping effect of the arc clamping block on the PVC pipe is not affected.

[0020] The utility model is further configured as follows: the limiting member includes a locking bolt, a plurality of mounting holes are opened on the side wall of the guide plate in the vertical direction, a threaded hole is opened on the outer wall of the fixing plate, the threaded hole is connected with the mounting hole, and the locking bolt is threadedly connected with the threaded hole.

[0021] By adopting the above technical solution, when the fixing plate slides to a certain height, the fixing plate and the guide plate can be fixedly connected as one by passing the locking bolt through the mounting hole and threading the locking bolt with the threaded hole.

[0022] The beneficial effects of the utility model are:

[0023] 1. When the traction crawler assembly tows the PVC pipe, the driving mechanism is started to make the two arc-shaped clamping blocks slide in opposite directions until the inner walls of the two arc-shaped clamping blocks are in contact with the outer wall of the PVC pipe, so that the two arc-shaped clamping blocks provide guiding support for the traction of the PVC pipe, thereby preventing the PVC pipe from deviating from the traction machine when being towed.

[0024] 2. Drive the double-headed screw to rotate, so that the mounting plates located at both ends of the double-headed screw can slide towards each other, and then the mounting plates can drive the arc-shaped clamping blocks to slide towards each other to clamp the PVC pipe.

[0025] 3. When the arc-shaped clamping block approaches the PVC pipe, the PVC pipe will abut against the outer wall of the guide wheel. When the PVC pipe moves, the guide wheel will rotate. The rotation of the guide wheel will convert the sliding friction between the PVC pipe and the arc-shaped clamping block into rolling friction, reducing the resistance between the two, thereby making the transportation of the PVC pipe smoother.

[0031] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations.

[0032] like Figure 1As shown, a PVC pipe traction machine disclosed in the present application includes a working platform 1, a traction crawler assembly 2 fixedly connected to the working platform 1 and used to traction the PVC pipe, two fixed plates 3 and two arc-shaped clamping blocks 4. The two fixed plates 3 are both fixedly connected to the working platform 1 and are respectively located at one end of the traction crawler assembly 2 close to the conveying direction of the PVC pipe, and the two fixed plates 3 are symmetrically arranged relative to the traction crawler assembly 2. Among them, the two arc-shaped clamping blocks 4 are used to clamp the PVC pipe, and the two arc-shaped clamping blocks 4 are relatively slidably arranged between the two fixed plates 3, and a driving mechanism for driving the arc-shaped clamping blocks 4 is also arranged between the two fixed plates 3.

[0033] When the traction track assembly 2 tows the PVC pipe, the driving mechanism is started to make the two arc-shaped clamping blocks 4 slide in opposite directions until the inner walls of the two arc-shaped clamping blocks 4 abut against the outer wall of the PVC pipe, so that the two arc-shaped clamping blocks 4 provide guiding support for the traction of the PVC pipe, thereby preventing the PVC pipe from deviating from the traction machine when being towed.

[0034] like Figure 2 As shown, the driving mechanism includes two mounting plates 5 and a double-headed screw 6:

[0035] The double-headed screw 6 is rotatably connected between the two fixed plates 3, the threads at both ends of the double-headed screw 6 are in opposite directions, the two mounting plates 5 are respectively threadedly connected to the two ends of the double-headed screw 6, and the two mounting plates 5 are respectively fixedly connected to the outer side walls of the two arc-shaped clamping blocks 4. One end of the double-headed screw 6 extends to the outside of the fixed plate 3 and is fixedly connected to a rotating disk 7, and a plurality of anti-sliding blocks are distributed in an equidistant circumferential array on the outer peripheral wall of the rotating disk to make it easier to rotate the rotating disk.

[0036] The rotating disk can drive the double-headed screw 6 to rotate, and the rotating double-headed screw 6 can make the mounting plates 5 located at both ends of the double-headed screw 6 slide in a direction close to each other, and then the mounting plates 5 can drive the arc-shaped clamping blocks 4 to slide in a direction close to each other to clamp the PVC pipe. At the same time, the rotating disk is provided to increase the force points for rotating the double-headed screw 6, making it more labor-saving to rotate the double-headed screw 6.

[0037] like Figure 3 As shown, a plurality of guide wheels 8 are rotatably provided on the inner walls opposite to each other of the two arc-shaped clamping blocks 4, and the rotation radial direction of the guide wheels 8 is toward the conveying direction of the PVC pipe.

[0038] When the arc-shaped clamping block 4 approaches the PVC pipe, the PVC pipe will abut against the outer wall of the guide wheel 8. When the PVC pipe moves, the guide wheel 8 will rotate. The rotation of the guide wheel 8 will convert the sliding friction between the PVC pipe and the arc-shaped clamping block 4 into rolling friction, reducing the resistance between the two, thereby making the transportation of the PVC pipe smoother.

[0039] like Figure 1 and Figure 4 As shown, the upper end surface of the working platform 1 is fixedly connected with two guide plates 9, and the two fixing plates 3 are respectively inserted in the two guide plates 9. The fixing plates 3 slide in the guide plates 9 along the vertical direction. The guide plates 9 are also provided with a limiter for limiting the sliding of the fixing plates 3. The limiter includes a locking bolt 10, and a plurality of mounting holes 11 are provided on the side wall of the guide plate 9 along the vertical direction. The plurality of mounting holes 11 are distributed in an equidistant array. A threaded hole 12 is provided on the outer wall of the fixing plate 3, and the threaded hole 12 is connected with the mounting hole 11. The locking bolt 10 is threadedly connected with the threaded hole 12.

[0040] When the height of the arc-shaped clamping block 4 cannot be aligned with the traction height of the PVC pipe, first release the limit of the locking bolt 10 on the fixing plate 3, then pull the fixing plate 3 to make the fixing plate 3 slide in the guide plate 9 to the actual required height, and finally reinsert the locking bolt 10 through the mounting hole 11, and thread the locking bolt 10 with the threaded hole 12 to fix the fixing plate 3 and the guide plate 9 together, thereby ensuring that the clamping effect of the arc-shaped clamping block 4 on the PVC pipe is not affected.

[0041] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments.
