Description

Technical Field

[0001] The invention belongs to the technical field of power cable installation, and in particular is a power cable threading and positioning device. Background Art

[0002] At present, based on the consideration of electricity safety, power cables need to be inserted into protective pipes during installation, and the protective pipes are used to provide protection for the power cables.

[0003] In the prior art, the threading operation between the power cable and the protective pipe is mostly carried out manually or with the help of a traction device. When manual threading is used, the cable needs to be pushed into the protective pipe continuously by a person. However, during the pushing process, the cable is relatively soft and is easily bent outside the protective pipe due to uneven force, resulting in poor cable threading effect. At the same time, the cable is easily damaged when it is bent. When a traction device is used for threading, one end of the traction wire in the traction device is passed through the protective pipe in advance, and then the end of the traction wire is connected to the cable. Finally, the traction device pulls the traction wire, thereby pulling one end of the cable into the protective pipe and allowing the entire cable to pass through the protective pipe. This threading method involves two threading operations in the protective pipe, resulting in cumbersome threading steps and low threading efficiency. Summary of the invention

The driving assembly 20 is arranged on the upper part of the base plate 10, and is used to drive the movable positioning assembly 30 to move back and forth toward the fixed positioning assembly 50. When the movable positioning assembly 30 moves toward the fixed positioning assembly 50, the first limiting assembly 70 is used to confine the cable inside the movable positioning assembly 30, and the second limiting assembly 40 releases the limitation on the cable. When the movable positioning assembly 30 moves in a direction away from the fixed positioning assembly 50, the second limiting assembly 40 is used to confine the cable inside the fixed positioning assembly 50, and the first limiting assembly 70 releases the limitation on the cable.

[0037] When performing the threading operation, the protective pipe 60 can be fixed on the side of the fixed positioning component 50 away from the movable positioning component 30, and then the roller with the cable wound on it can be mounted on the upper part of the bottom plate 10, so that the roller is located on the side of the movable positioning component 30 away from the fixed positioning component 50, and then one end of the cable is passed through the movable positioning component 30 and the fixed positioning component 50 in turn, so that one end of the cable extends into the protective pipe 60, and then the driving component 20 drives the movable positioning component 30 to move back and forth toward the fixed positioning component 50. When the movable positioning component 30 moves toward the fixed positioning component 50, the first limit component 70 confines the cable inside the movable positioning component 30, and at the same time The second limiting assembly 40 releases the cable from the restricted state inside the fixed positioning assembly 50, and the movable positioning assembly 30 pushes the cable so that the cable moves toward the inside of the protective pipe 60.

[0039] By inserting one end of the protective pipe 60 from the fixed support seat 502 away from the side of the fixed positioning sleeve 501 into the wire passing hole, and then turning the locking bolt 503, the locking bolt 503 is screwed into the wire passing hole, and then the protective pipe 60 is supported and fixed inside the wire passing hole, so that the protective pipe 60 is correspondingly connected with the fixed positioning sleeve 501, and then one end of the cable is successively passed through the movable positioning sleeve 301 and the fixed positioning sleeve 501 and extended into the protective pipe 60, and then the driving component 20 drives the movable support seat 302 and the movable positioning sleeve 301 to move back and forth, and utilizes the cooperation of the first limit component 70 and the second limit component 40 to continuously deliver the cable to the inside of the protective pipe 60, so as to realize the automatic threading operation between the cable and the protective pipe 60.

[0040] See also Figure 3 , Figure 4 and Figure 5 In one embodiment, the first limiting assembly 70 includes a plurality of paddles, and the plurality of paddles are hingedly mounted on the inner wall of the movable positioning sleeve 301, and the plurality of paddles are tiltedly distributed, and one side of each group of paddles is connected to the inner wall of the movable positioning sleeve 301 through a group of third elastic members (not shown in the figure), and a U-shaped bracket 504 is fixedly arranged on the outer wall of the fixed positioning sleeve 501, and a vertically distributed third slide rail 505 is fixedly arranged on the inner wall of the U-shaped bracket 504, and a through hole 506 is opened on the side wall of the fixed positioning sleeve 501, and the second limiting assembly 40 includes a support rod 401, a pressure plate 402 and a limiting rod 405, one end of the support rod 401 is fixedly connected to the side wall of the movable support seat 302, and the other end is connected from the The U-shaped bracket 504 passes through the inside, and the pressure plate 402 is slidably installed on the bottom wall of the support rod 401. One end of the pressure plate 402 is provided with an inclined surface, and one side of the pressure plate 402 is provided with an oblique mouth 403. The limiting rod 405 is arranged on the inner side of the U-shaped bracket 504, and an extension rod 407 is fixedly arranged on the side wall of the limiting rod 405. The end of the extension rod 407 away from the limiting rod 405 is slidably matched with the third slide rail 505 through a slider (not shown in the figure), and one side of the extension rod 407 is connected to the inner wall of the U-shaped bracket 504 through a first elastic member 406. A support plate 404 is fixedly arranged on the bottom wall of the support rod 401, and the support plate 404 and the pressure plate 403 are connected through a second elastic member 409.

[0041] When one end of the cable passes through the movable positioning sleeve 301 and the fixed positioning sleeve 501 in turn and extends into the protective pipe 60, the driving assembly 20 drives the movable support seat 302 and the movable positioning sleeve 301 to move away from the fixed positioning sleeve 501, the movable support seat 302 drives the support rod 401 to move synchronously, and the support rod 401 drives the pressure plate 402 to move synchronously. When the pressure plate 402 moves, the inclined surface of one end of the pressure plate acts on the upper end of the limit rod 405 to drive the limit rod 405 to move downward. When the limit rod 405 moves downward, the first elastic member 406 is stretched by force, and at the same time, the lower end of the limit rod 405 enters the fixed positioning sleeve 501 from the through hole 506 and acts on the fixed positioning sleeve 501. The cable side wall is used to limit the cable inside the fixed positioning sleeve 501 to prevent the cable from being brought out from the protective pipe 60 when the movable positioning sleeve 301 moves away from the fixed positioning sleeve 501. As the movable positioning sleeve 301 moves away from the fixed positioning sleeve 501, a plurality of paddles inside the movable positioning sleeve 301 slide along the outer wall of the cable, and the movable positioning sleeve 301 straightens the external cable until the movable positioning sleeve 301 moves a certain distance, and the upper end of the limiting rod 405 slides from the bottom of the pressing plate 402 to the inside of the oblique opening 403. Under the pulling action of the first elastic member 406, the limiting rod 405 moves up, and the lower end of the limiting rod 405 withdraws from the inside of the through hole 506 to release the fixed positioning sleeve. 501 is a limited state of the internal cable. When the limit rod 405 moves upward, it pushes the pressure plate 402 so that the pressure plate 402 slides along the bottom wall of the support rod 401. The second elastic member 409 is compressed. When the pressure plate 402 slides, its side wall contacts the limit rod 405. Then the driving assembly 20 drives the movable support seat 302 and the movable positioning sleeve 301 to move toward the fixed positioning sleeve 501. The movable support seat 302 drives the support rod 401 to move in the opposite direction. The support rod 401 drives the pressure plate 402 to move in the opposite direction. At this time, the limit rod 405 is attached to the side wall of the pressure plate 402 and slides in the opposite direction. Several paddles on the inner wall of the movable positioning sleeve 301 are supported to the outer wall of the cable, thereby pushing the cable so that the cable moves toward the inside of the protective pipe 60. Move until the limiting rod 405 slides off the side wall of the pressure plate 402, and the second elastic member 409 pushes the pressure plate 402 so that the pressure plate 402 slides in the opposite direction along the bottom wall of the support rod 401, thereby realizing the resetting of the pressure plate 402, and then the driving assembly 20 drives the movable support seat 302 and the movable positioning sleeve 301 to move away from the fixed positioning sleeve 501 again, and the pressure plate 402 presses the limiting rod 405 down again, and the limiting rod 405 limits the cable inside the fixed positioning sleeve 501 again, and the movable positioning sleeve 301 slides along the outer wall of the cable again... Such a reciprocating cycle can realize the continuous and automatic delivery of the cable into the protective pipe 60, thereby realizing the threading operation of the cable and the protective pipe 60.

[0042] See also Figure 1In one embodiment, a first slide rail 101 is fixedly provided on the upper portion of the base plate 10 , and a first slide rail groove (not shown in the figure) adapted to the first slide rail 101 is provided at the bottom of the movable support seat 302 .

[0044] In one embodiment, the first elastic member 406 , the second elastic member 409 and the third elastic member may be springs or metal springs, which are not limited here.

[0045] In one embodiment, the output end of the driving component 20 is connected to the movable support seat 301. The driving component 20 can be a hydraulic cylinder or a linear motor, which is not limited here.

[0046] In the embodiment of the present invention, when performing a threading operation, the protective pipe 60 can be fixed on a side of the fixed positioning component 50 away from the movable positioning component 30, and then the roller with the cable wound thereon is mounted on the upper part of the bottom plate 10 on a side of the movable positioning component 30 away from the fixed positioning component 50, and then one end of the cable is passed through the movable positioning component 30 and the fixed positioning component 50 in sequence, so that one end of the cable extends into the protective pipe 60, and then the driving component 20 drives the movable positioning component 30 to reciprocate toward the fixed positioning component 50. When the movable positioning component 30 moves toward the fixed positioning component 50, the first limiting component 70 confines the cable inside the movable positioning component 30, and at the same time, the second limiting component 40 releases the cable from the fixed positioning component 50. The movable positioning component 30 pushes the cable to move into the protective pipe 60. When the movable positioning component 30 moves in a direction away from the fixed positioning component 50, the second limiting component 40 limits the cable inside the fixed positioning component 50. At the same time, the first limiting component 70 releases the limited state of the cable inside the movable positioning component 30. The movable positioning component 30 moves away from the fixed positioning component 50 compared to the cable. In this way, the cable can be continuously delivered to the inside of the protective pipe 60 through the reciprocating movement of the movable positioning component 30, thereby realizing the automatic threading operation between the cable and the protective pipe 60. Compared with the prior art, the automatic threading operation between the cable and the protective pipe 60 can be realized, which has the advantages of good threading effect and high threading efficiency.
