Description

Technical Field

[0001] The present invention relates to the technical field of protection pipes, and particularly to a PVC cable protection pipe with a cable splitting function. Background Art

[0002] In the fields of modern power transmission and communication, as an important carrier for power and signal transmission, the safety and stability of cables are of crucial importance. PVC cable protection pipes are widely used in the laying projects of various cables due to their excellent chemical corrosion resistance, good insulation performance, relatively low cost, and convenient construction. They can effectively protect cables from physical damage and chemical corrosion in the external environment.

[0003] With the continuous development of urban construction and the continuous progress of the power and communication industries, the scenarios of cable laying are becoming increasingly complex and diverse, and the functional requirements for cable protection pipes are also getting higher and higher. In many large buildings, underground utility tunnels, industrial parks and other places, it is often necessary to lay multiple cables of different specifications and uses at the same time. Most traditional PVC cable protection pipes only have a single cable accommodation space and cannot effectively separate different types of cables. When multiple cables are inserted into the same protection pipe together, it is easy for the cables to be entangled and squeezed with each other, which not only increases the difficulty of cable installation and maintenance, but also during the operation of the cables, due to the different heat generation conditions of different cables, the heat conduction between them may cause the local temperature to be too high, affecting the normal service life of the cables and even posing potential safety hazards.

[0004] In addition, in some occasions where cable classification management is required, such as separating power cables and communication cables to avoid electromagnetic interference, traditional PVC cable protection pipes cannot meet this requirement, and additional complex measures need to be taken to achieve cable classification, increasing the project cost and construction difficulty.

[0005] Therefore, it is very necessary to invent a PVC cable protection pipe with a cable splitting function, which can adjust the cable accommodation space inside the protection ring according to the actual laying requirements. Summary of the Invention

[0006] In view of the above problems, the present invention proposes a PVC cable protection pipe with a cable splitting function, and the technical solution used is as follows:

[0007] A PVC cable protection pipe with a cable splitting function includes an outer pipe, a plurality of fixed rings fixedly installed inside the outer pipe, a plurality of rotating rings rotatably installed inside the outer pipe, an adjusting mechanism for controlling the rotation of the corresponding rotating rings, and a traction mechanism for pulling the end of the cable to move.

[0008] The fixed ring is fixedly provided with a fixed ring partition plate, and the rotating ring is fixedly provided with a rotating ring partition plate; a fixed clamp rod is slidably and elastically installed on the rotating ring; a plurality of fixing holes corresponding to the fixed clamp rod are provided on the outer tube; a plurality of outer tube cable grooves are provided on the inner side wall of the outer tube, and a plurality of fixed ring cable grooves docked with the outer tube cable grooves are provided on the inner side wall of the fixed ring; a plurality of rotating ring cable grooves intermittently docked with the outer tube cable grooves are provided on the inner side wall of the rotating ring;

[0010] Furthermore, a card block and an adjustment toggle block are fixedly provided on the rotating ring corresponding to the respective positions on the adjustment rod, and an adjustment block for intermittently toggling the adjustment toggle block is fixedly installed on the sliding sleeve; an adjustment card slot is provided on the rotating ring partition plate, and the card block intermittently enters the adjustment card slot.

[0011] Furthermore, the traction mechanism includes a clamp and a clamp mounting ring; the clamp mounting ring is coaxially rotatably mounted on the front end of the outer tube, a mounting block is fixedly mounted thereon, and a moving block that can be engaged and mounted on the mounting block is provided; the moving block can slide on the outer tube cable groove, the fixed ring cable groove and the rotating ring cable groove; the clamp is fixedly mounted on the moving block.

[0012] Furthermore, the sliding assembly includes a fixing frame and a screw rod; the fixing frame is fixedly mounted on the outer tube; the screw rod is rotatably mounted on the fixing frame; and the sliding sleeve is threadedly mounted on the screw rod.

Each small compartment can accommodate a cable. According to the actual laying requirements, by adjusting the angles of all the rotating rings, the cable accommodation space inside the protection ring is adjusted, thereby achieving the cable separation effect.

[0047] A handle is fixedly provided on the front end of the adjusting tube 404 for rotating the adjusting tube 404 .

[0048] like Figures 1 - 5 , Figures 8 - 9 and Figure 20 As shown, the clamping jaw mounting ring 6 is coaxially rotatably mounted on the front end of the outer tube 1, on which a mounting block 602 is fixedly mounted, and a moving block 601 that can be embedded and mounted on the mounting block 602 is provided, and the moving block 601 can slide on the outer tube cable groove 101, the fixed ring cable groove 202 and the rotating ring cable groove 302; the clamping jaw 5 is fixedly mounted on the moving block 601; and a rope (not shown in the figure) is fixedly provided on the clamping jaw 5.

[0049] In this embodiment, the three groups of rotating rings 3 are painted with different colors, and the corresponding three pairs of adjusting levers 407 are painted with corresponding colors.

[0050] The working principle of this embodiment is as follows:

[0051] When adjusting the angle of the rotating ring 3 (taking the 90° rotating ring 3 as an example), the operator rotates the screw rod 406, the sliding sleeve 405 moves backward, and the pair of adjusting clamping rods 407 corresponding to the rotating ring 3 to be adjusted will move radially outward (the adjusting block 4051 on the sliding sleeve 405 will push the adjusting toggle block 4072 on the pair of adjusting clamping rods 407 outward). When the operator observes that the adjusting clamping rod 407 corresponding to the 90° rotating ring 3 moves outward into position, the clamping block 4071 on the adjusting clamping rod 407 moves inward. Insert the rotating ring 3, stop rotating the screw rod 406 at this time, adjust the clamping rod 407, the corresponding rotating ring 3 and the adjusting tube 404 are relatively fixed, then pull out the limit frame 408, rotate the adjusting tube 404 by the handle, the front support ring 402 and the rear support ring 403 rotate synchronously, so that the group of rotating rings 3 rotate 90°, the fixed clamping rod 303 on the rotating ring 3 is separated from the original fixing hole 102, and moves to another group of fixing holes 102 with the rotation of the rotating ring 3, so that the group of rotating rings 3 completes the rotation of 90°.

[0052] After the angles of all rotating rings 3 are adjusted, small compartments are formed between the fixed ring partition plate 201 and the rotating ring partition plate 301 or between the rotating ring partition plates 301 and 301, and each small compartment has a cable distribution groove formed by connecting the outer tube cable distribution groove 101, the fixed ring cable distribution groove 202 and the rotating ring cable distribution groove 302.

[0053] When splitting cables, rotate the clamping jaw mounting ring 6 to move the moving block 601 and the mounting block 602 to the front end of the small compartment, and dock the mounting block 602 with the cable splitting groove of the small compartment. Then clamp the split cables on the clamping jaw 5, and gradually move the cables into the small compartment. The moving block 601 enters the cable splitting groove and moves backward until the cable end moves to the rear end of the outer tube 1. Release the clamping jaw 5, pull the rope on the clamping jaw 5 from the front end, and the clamping jaw 5 and the moving block 601 return to the front end to complete a cable split.
