Description

Technical Field

[0001] This utility model relates to the field of cable protection pipe production technology, and in particular to a traction device for cable protection pipe production. Background Technology

[0002] The traction device for cable protection pipe production is a specialized piece of equipment that achieves continuous and stable traction of the pipe through the coordinated operation of mechanical structure and drive system. It is suitable for cable protection pipe production scenarios using materials such as PVC and MPP.

[0003] Currently, during the traction process of cable protection pipes, a traction device is usually used to clamp and pull the cable protection pipes. However, the cable protection pipes located on both sides of the traction device and the clamped parts of the traction device are subjected to uneven force, which causes the cable protection pipes located on both sides of the traction device to sink due to the weight. This makes the cable protection pipes prone to falling during the production traction process, affecting the production quality of the cable protection pipes.

[0004] Meanwhile, during the production and traction process, the cable protection pipe cannot stop the speed of the traction device. If the speed of the traction device is too fast, it may cause the cable protection pipe to break during the traction process or the diameter of the cable protection pipe to be different due to different traction speeds.

[0005] Therefore, we propose a traction device for the production of cable protection pipes to solve the problems mentioned above. Utility Model Content

[0006] Two sets of lifting blocks can be used to support the surface of the cable protection pipe, preventing it from bending due to uneven weight distribution during traction. At the same time, the friction blocks and rubber strips can increase the friction between the traction plate and the lead screw during traction, thereby reducing the moving speed of the traction plate and preventing poor traction quality caused by excessively fast traction speed. This solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: including a traction plate, a lifting mechanism, a first limiting mechanism and a second limiting mechanism, wherein the lifting mechanism includes a spring and a lifting block, the lower surface of the lifting block is fixedly connected to the top surface of the spring, the lifting block and the spring are used to adjust the distance between the lifting block in real time according to the diameter of the cable protection pipe, and the lifting block can lift the cable protection pipe being pulled to prevent bending of the cable protection pipe during the pulling process;

[0008] The first limiting mechanism includes a friction block, and the second limiting mechanism includes a rubber strip. The friction block and the rubber strip are used to block the traction speed of the cable protection pipe and prevent the traction speed of the cable protection pipe from being too fast, which would affect the traction quality of the cable protection pipe.

[0009] Preferably, the lifting mechanism further includes a connecting plate, which is fixedly connected to both sides of the traction plate. A hollow plate is fixedly connected to the upper surface of the connecting plate. An adjusting plate is slidably connected inside the hollow plate. A hollow tube is slidably connected inside the adjusting plate, and the inner bottom wall of the hollow tube is fixedly connected to the bottom end face of the spring. A fixing rod is fitted onto the rear surface of the hollow plate, and the fixing rod is fitted onto the adjusting plate.

[0010] Preferably, the first limiting mechanism further includes a horizontal plate, which is fixedly connected to both sides of the traction plate. A counterweight is fixedly connected to the lower surface of the horizontal plate, and the inner wall of the counterweight is connected to the friction block.

[0011] Preferably, the second limiting mechanism further includes a connecting column, which is fixedly connected to the side surface of the counterweight. A joint is movably connected inside the connecting column, and a bonding plate is fixedly connected to the end of the joint away from the connecting column. The side surface of the bonding plate is connected to a rubber strip.

[0012] Preferably, a push rod is fitted onto the outer surface of the traction plate, and a metal plate is fixedly connected to the end of the push rod away from the traction plate. A threaded rod is threadedly connected to the inside of the metal plate, and the threaded rod is threadedly connected to the inside of the traction plate. A pressing block is fixedly connected to the end of the threaded rod away from the metal plate, and an adjusting ring plate is fixedly connected to the end of the push rod away from the metal plate.

[0013] Preferably, a first mounting base is slidably connected to the lower surface of the traction plate, a motor is fixedly connected to the side surface of the first mounting base, a lead screw is fixedly connected to the output end of the motor, and the lead screw is threadedly connected to the inside of the traction plate. The outer surface of the lead screw is in contact with the lower surface of the friction block and the rubber strip. A second mounting base is slidably connected to the lower surface of the traction plate, and a limit rod is provided inside the second mounting base, and the limit rod is slidably connected to the inside of the traction plate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the height of the adjusting plate can be adjusted according to the diameter of the cable protection pipe by utilizing the sliding between the adjusting plate and the hollow plate. After the height of the adjusting plate is adjusted, the two ends of the fixing rod can be inserted into the interior of the adjusting plate and the hollow plate respectively to fix the adjusting plate, so that the lifting block can fit against both sides of the cable protection pipe. By utilizing the elasticity of the spring and the sliding connection between the hollow tube and the adjusting plate, the lifting plate can be adjusted in real time according to the diameter of the cable protection pipe. The lifting block can distribute the weight of the cable protection pipe pulled in the traction plate, preventing the weight of the cable protection pipe from being concentrated in the interior of the traction plate, thus preventing uneven gravity on both sides of the traction plate and phenomena such as bending.

[0016] 2. In this utility model, since the lower surface of the counterweight is provided with an arc groove, the diameter of which is larger than that of the lead screw, allowing the counterweight to be fitted onto the surface of the lead screw. The friction block can be pressed against the outer surface of the lead screw. By utilizing the movement of the joint and the connecting column, the angle of the bonding plate can be adjusted. By continuously adjusting the angle of the bonding plate, the rubber strip can be bonded to the upper surface of the lead screw. When the lead screw drives the traction plate to move, the friction between the lead screw and the traction plate is increased by the contact between the friction block, the rubber strip, and the surface of the lead screw. When the traction plate moves, the lead screw is affected by the friction between the friction block and the rubber strip, and the moving speed of the traction plate is relatively slow, preventing the traction speed of the traction plate from being too fast and causing poor traction quality of the cable protection pipe.

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as shown in the attached document Figure 1 - Figure 3 As shown, it includes a traction plate 1, a lifting mechanism 3, a first limiting mechanism 8 and a second limiting mechanism 11. The lifting mechanism 3 includes a spring 305 and a lifting block 304. The lower surface of the lifting block 304 is fixedly connected to the top surface of the spring 305. The lifting block 304 and the spring 305 are used to adjust the distance between the lifting block 304 in real time according to the diameter of the cable protection pipe. The lifting block 304 can lift the cable protection pipe being pulled to prevent the cable protection pipe from bending during the pulling process.

[0025] The first limiting mechanism 8 includes a friction block 803, and the second limiting mechanism 11 includes a rubber strip 113. The friction block 803 and the rubber strip 113 are used to block the traction speed of the cable protection pipe and prevent the traction speed of the cable protection pipe from being too fast and affecting the traction quality of the cable protection pipe.

[0026] The effect achieved by the entire embodiment 1 is as follows: when the cable protection pipe is being pulled during production, the two sets of lifting blocks 304 can lift the surface of the cable protection pipe to prevent it from bending due to uneven weight during the pulling process. At the same time, when the cable protection pipe is being pulled, the friction block 803 and the rubber strip 113 can increase the friction between the pulling plate 1 and the lead screw 10, thereby reducing the moving speed of the pulling plate 1 and preventing the cable protection pipe from being pulled poorly due to excessively fast moving speed.

[0027] Example 2, as Figure 1 - Figure 2 As shown, the lifting mechanism 3 also includes a connecting plate 301, which is fixedly connected to both sides of the traction plate 1. A hollow plate 302 is fixedly connected to the upper surface of the connecting plate 301. An adjusting plate 303 is slidably connected inside the hollow plate 302. A hollow tube 307 is slidably connected inside the adjusting plate 303. The inner bottom wall of the hollow tube 307 is fixedly connected to the bottom end face of the spring 305. A fixing rod 306 is fitted and connected to the rear surface of the hollow plate 302. The fixing rod 306 is fitted and connected to the adjusting plate 303.

[0028] The effect achieved by the entire embodiment 2 is as follows: by utilizing the sliding between the adjusting plate 303 and the hollow plate 302, the height of the adjusting plate 303 can be adjusted according to the diameter of the cable protection pipe. After the height of the adjusting plate 303 is adjusted, the two ends of the fixing rod 306 can be inserted into the interior of the adjusting plate 303 and the hollow plate 302 respectively to fix the adjusting plate 303, so that the lifting block 304 can fit against both sides of the cable protection pipe. By utilizing the elasticity of the spring 305 and the sliding connection between the hollow tube 307 and the adjusting plate 303, the lifting plate can be adjusted in real time according to the diameter of the cable protection pipe. The lifting block 304 can distribute the weight of the cable protection pipe pulled in the traction plate 1, preventing the weight of the cable protection pipe from being concentrated in the traction plate 1, and preventing uneven gravity on both sides of the traction plate 1, which could cause bending or other phenomena.

[0029] Example 3, as Figure 1 and Figure 3 The first limiting mechanism 8 also includes a horizontal plate 801, which is fixedly connected to both sides of the traction plate 1. A counterweight 802 is fixedly connected to the lower surface of the horizontal plate 801, and the inner wall of the counterweight 802 is connected to the friction block 803. The second limiting mechanism 11 also includes a connecting column 111, which is fixedly connected to the side surface of the counterweight 802. A joint 112 is movably connected inside the connecting column 111. A bonding plate 114 is fixedly connected to the end of the joint 112 away from the connecting column 111, and the side surface of the bonding plate 114 is connected to the rubber strip 113.

[0030] The overall effect achieved by embodiment 3 is as follows: Since the lower surface of the counterweight 802 is provided with an arc groove, the diameter of which is larger than that of the lead screw 10, the counterweight 802 can be fitted onto the surface of the lead screw 10. The friction block 803 can be pressed against the outer surface of the lead screw 10. By utilizing the movement of the joint 112 and the connecting column 111, the angle of the bonding plate 114 can be adjusted. By continuously adjusting the angle of the bonding plate 114, the rubber strip 113 can be pressed against the upper surface of the lead screw 10. When the lead screw 10 drives the traction plate 1 to move, the friction between the lead screw 10 and the traction plate 1 can be increased by the contact between the friction block 803, the rubber strip 113 and the surface of the lead screw 10. When the traction plate 1 moves, the lead screw 10 is affected by the friction between the friction block 803 and the rubber strip 113, and the moving speed of the traction plate is relatively slow, preventing the moving speed of the traction plate 1 from being too fast and causing poor traction quality of the cable protection pipe.

[0031] Example 4, as Figure 1 and Figure 4As shown, a push rod 12 is fitted onto the outer surface of the traction plate 1. A metal plate 9 is fixedly connected to the end of the push rod 12 away from the traction plate 1. A threaded rod 14 is threadedly connected to the inside of the metal plate 9, and the threaded rod 14 is threadedly connected to the inside of the traction plate 1. A pressing block 13 is fixedly connected to the end of the threaded rod 14 away from the metal plate 9. An adjusting ring plate 2 is fixedly connected to the end of the push rod 12 away from the metal plate 9. A first mounting seat 7 is slidably connected to the lower surface of the traction plate 1. A motor 6 is fixedly connected to the side surface of the first mounting seat 7. A lead screw 10 is fixedly connected to the output end of the motor 6, and the lead screw 10 is threadedly connected to the inside of the traction plate 1. The outer surface of the lead screw 10 is in contact with the lower surface of the friction block 803 and the rubber strip 113. A second mounting seat 5 is slidably connected to the lower surface of the traction plate 1. A limit rod 4 is provided inside the second mounting seat 5, and the limit rod 4 is slidably connected to the inside of the traction plate 1.

[0032] The overall effect of embodiment 4 is as follows: When the cable protection pipe is being pulled, one end of the cable protection pipe can be passed through the interior of the traction plate 1. According to the diameter of the cable protection pipe, the push rod 12 can be pushed downward by the metal plate 9, so that the push rod 12 can drive the adjusting ring plate 2 to move. When the adjusting ring plate 2 is in contact with the surface of the cable protection pipe, the threaded rod 14 can be turned to fix the metal plate 9, so that the adjusting ring plate 2 can clamp the cable protection pipe in the traction plate 1. The motor 6 is connected to the external power supply, and the motor 6 can be started to drive the lead screw 10 to rotate. According to the rotation of the lead screw 10, the traction plate 1 can be moved. When the traction plate 1 is moving, it can pull the cable protection pipe to move, thereby pulling the cable protection pipe. Since the rear lower surface of the traction plate 1 slides with the limiting rod, the limiting rod can guide the movement of the traction plate 1, so that the traction plate 1 slides normally on the surface of the first mounting plate and the second mounting plate to pull the cable protection pipe.

[0033] The working principle of the entire device is as follows: one end of the cable protection tube is inserted through the interior of the traction plate 1. According to the diameter of the cable protection tube, the push rod 12 can be pushed downward using the metal plate 9, so that the push rod 12 can drive the adjusting ring plate 2 to move. When the adjusting ring plate 2 is in contact with the surface of the cable protection tube, the threaded rod 14 can be turned to fix the metal plate 9, so that the adjusting ring plate 2 can clamp the cable protection tube in the traction plate 1. By using the sliding between the adjusting plate 303 and the hollow plate 302, the height of the adjusting plate 303 can be adjusted according to the diameter of the cable protection tube. The lifting block 304 can be in contact with both sides of the cable protection tube. By using the elasticity of the spring 305 and the sliding connection between the hollow tube 307 and the adjusting plate 303, the lifting plate can be adjusted in real time according to the diameter of the cable protection tube.

[0034] The friction block 803 can be pressed against the outer surface of the lead screw 10. By utilizing the movement of the joint 112 and the connecting column 111, the angle of the bonding plate 114 can be adjusted. By continuously adjusting the angle of the bonding plate 114, the rubber strip 113 can be pressed against the upper surface of the lead screw 10. When the lead screw 10 drives the traction plate 1 to move, the friction between the lead screw 10 and the traction plate 1 can be increased by the contact between the friction block 803, the rubber strip 113 and the surface of the lead screw 10. Starting the motor 6 can drive the lead screw 10 to rotate. The rotation of the lead screw 10 can drive the traction plate 1 to move. When the traction plate 1 moves, it can pull the cable protection pipe to move, thereby pulling the cable protection pipe for production.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
