Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction equipment, in particular to a construction cable retracting and releasing device. Background Art
[0002] Cables are essential for construction work. When retracting and releasing cables, pay attention to their bend radius. A bend radius that is too small can damage the cable, so it's important to maintain an appropriate bend radius to ensure its integrity and service life. Care should also be taken to avoid obstacles within the work area, such as pipes and wires. During cable retraction and release, the cable can sometimes become tangled. In such cases, it's necessary to stop retracting and carefully resolve the tangling issue. Retracting and releasing cables too quickly can cause them to become tangled or even damaged. Therefore, when retracting and releasing cables, not only must you be able to stop immediately, but you must also control the cable's winding direction to prevent damage from tangling or bending. Utility Model Content

[0016] The lock 10 includes a support frame 11, a spring 12 and a latch 13. The support frame 11 is fixed to the support frame 1 corresponding to the position of the through hole 9. The support frame 11 is provided with a mounting hole along the axial direction of the winding drum 8. The latch 13 passes through the mounting hole and is aligned with the through hole 9. A group of connecting holes 20 are also provided on the latch 13 to facilitate the insertion of bolts to adjust the moving position of the latch 13. The spring 12 is sleeved on the latch 13 and is located in the support seat. The end of the spring 12 close to the through hole 9 is limited by a clamp so that the latch 13 is normally extended and connected to the through hole 9. When the line is retracted, the latch 13 is pulled out. When the through hole 9 is aligned with the axis of the latch 13, the bolt on the latch 13 can be contacted, so that the latch 13 is reset inward under the action of the spring 12 and connected with the through hole 9, which limits the winding drum 8 and completes the retraction and extension action.
[0017] The guide frame 3 includes a bearing seat 14, a connecting shaft 15, a sleeve 16 and a guide ring 17. The bearing seats 14 are oppositely arranged at the top of the support frame 1. The connecting shaft 15 is rotatably installed between the two bearing seats 14. The sleeve 16 is sleeved on the connecting shaft 15. The guide ring 17 is vertically connected to the outer contour of the sleeve 16. The cable is first initially guided by the limiter 4, and then guided to the winding drum 8 by the guide frame 3 for the second time. This guidance can control the position of the cable on the winding drum 8 during winding, and prevent uneven cable stacking during winding.
[0018] The limiter 4 includes a slide 18 that is sleeved on the support frame 1 and slidably connected to the support frame 1. A fastening bolt 19 is provided at the front end of the slide 18, and a group of connecting holes 20 connected to the fastening bolt 19 are opened on the corresponding support frame 1. The top of the slide 18 is connected to a guide ring 17. The cable on the ground first passes through the guide ring 17 and then is wound onto the winding drum 8. Conversely, the guidance of the cable can be controlled to prevent the cable from bending and dragging and causing losses. At the same time, the position of the slide 18 on the support frame 1 can be changed by the fastening bolt 19, so that the guide ring 17 can be freely adjusted along the winding drum, which is convenient for controlling the winding and unwinding direction and improving the winding and unwinding efficiency.
[0019] The winding drum 8 is also provided with a partition plate 21 parallel to both ends, which divides the winding drum 8 into a large and a small winding space. During construction, cables, optical cables or other cables can be retracted and released at the same time, which is suitable for the simultaneous retraction and release of cables over a shorter distance.
