The number of control, signaling, protection and power transmission cables required accounts for more than 60% of the entire subway project. Its construction quality is directly related to the safety and stability of subway operation.

[0003] Patent CN217867520U discloses a cable winding and unwinding device for subway electromechanical construction, including a positioning base plate. Two horizontally opposite fixed frames are fixedly mounted on the top of the positioning base plate. A winding and unwinding roller is provided between the two fixed frames. The two ends of the winding and unwinding roller are rotatably mounted on the fixed frames through clamping mechanisms. The clamping mechanism includes two mounting seats for mounting the corresponding ends of the winding and unwinding roller. At least one of the mounting seats has a mounting component that can extend and retract along the axial direction of the winding and unwinding roller at one end connected to the fixed frame. The mounting component is connected to the fixed frame. A number of partitions are fixedly mounted at intervals along the longitudinal direction of the outer wall of the winding and unwinding roller. The interval between adjacent partitions is used for winding the cable. A cleaning mechanism is provided on one side of the winding and unwinding roller for cleaning the cable.

[0034] The working principle of the cable winding and unwinding device for subway electromechanical construction in this embodiment is as follows: In use, the user can move the device to any position by using the movable wheel 3 in conjunction with the push rod 4. When installing the winding roller 5, first insert the locking block 22 at one end of the winding roller 5 into the locking groove 23 of the first clamping frame 16, pull the pull rod 26, the pull rod 26 slides along the first handle 25, the baffle 27 moves with the pull rod 26, and the insert block 28 moves out of the insertion hole with the baffle 27. Rotate the first handle 25, the first one-way screw 24 rotates with the first handle 25, the sliding support 15 rotates with the first one-way screw 24 and slides along the second sliding groove 19, the second rotating shaft 21 moves with the sliding support 15, and the second clamping frame 18 moves with the second rotating shaft 21 until the locking groove 23 of the second clamping frame 18 is fitted onto the winding roller 5. On the other end, the lever 26 is pushed by the locking block 22. The baffle 27 moves with the lever 26, and the insert block 28 moves with the baffle 27 and inserts into the insertion hole on the side wall of the base plate 1, locking the first handle 25 and clamping the winding roller 5. When laying the cable, the servo motor 17 rotates the output shaft, the first rotating shaft 20 rotates with the output shaft, the first clamping frame 16 rotates with the first rotating shaft 20, and the winding roller 5 rotates with the first clamping frame 16 to perform the laying operation. At this time, after the cable passes through the first guide roller 8, it slides on the outer wall of the second guide roller 10. Thus, through the elastic action of the return spring 11, the second slider 30 drives the second guide roller 10 to move elastically, thereby causing the second guide roller 10 to squeeze the cable. The cable slides upwards, keeping it taut under the direction and pull of the first guide roller 8. When storing the cable, rotating the third handle 47 causes the second one-way screw 46 to rotate with the third handle 47, and the third slider 42 to slide along the positioning frame 41 with the second one-way screw 46. The positioning block 43 moves out of the slot 45 with the third slider 42. Rotating the second handle 40 causes the rotating rod 38 to rotate with the second handle 40, and the second bevel gear 39 to rotate with the rotating rod 38. The first bevel gear 37 rotates with the second bevel gear 39, and the double-acting screw 35 rotates with the first bevel gear 37. The second slider 30 rotates along the third slide groove 33 with the double-acting screw 35, and the mounting bracket 31 moves with the second slider 30 until the two mounting brackets 31 contact each other. The arc-shaped groove 34 closes to form a through hole, and the cleaning cotton 32 contacts the outer wall of the cable. When the third handle 47 is rotated, the second one-way screw 46 rotates with the third handle 47, and the third slider 42 rotates with the second one-way screw 46 and slides along the positioning frame 41. The positioning block 43 moves with the third slider 42, passes through the slot 45 and inserts into the insertion hole on the side wall of the second slider 30, fixing the position between the second slider 30 and the vertical plate 6. The servo motor 17 reverses the output shaft, the first rotating shaft 20 rotates with the output shaft, the first clamping frame 16 rotates with the first rotating shaft 20, and the winding roller 5 rotates with the first clamping frame 16 to store the cable. The cleaning cotton 32 cleans the dust and water stains on the outer surface of the cable, reducing the potential hazards after the cable is stored.
