Description

Technical Field

[0001] This utility model relates to the field of low-voltage engineering technology, specifically a wiring device for low-voltage engineering. Background Technology

[0002] In modern building and information systems, low-voltage electrical engineering is a key area for realizing functions such as information transmission, equipment control, and security. The efficiency and quality of its cabling work are of paramount importance. Low-voltage electrical engineering mainly involves the design, installation, and maintenance of low-voltage, low-current electrical systems, aiming to build an information transmission network within a building or area, encompassing multiple systems such as structured cabling, security monitoring, and building automation.

[0003] A communication cable integrated cabling device, disclosed in CN216004818U, allows for automatic correction of bent cables during cable laying via limit wheels, saving time and effort and improving cabling efficiency. Through the configuration of a rotating shaft, winding frame, drive mechanism, and reciprocating mechanism, when excessive cable needs to be retracted, the drive mechanism rotates the winding frame, and the reciprocating mechanism automatically adjusts the cable winding position, saving time and effort and improving retraction efficiency.

[0004] This communication cable cabling device can automatically correct bent cables by using limit wheels during cable laying, saving time and effort. However, if the cable becomes slack during the laying process, it is easy for the cable to get tangled, making it impossible to pull and affecting its use. Therefore, it needs to be improved.

[0015] Compared with the prior art, this utility model provides a wiring device for low-voltage engineering, which has the following beneficial effects:

[0016] 1. In the wiring device for low-voltage engineering, the moving component is provided by a drive motor that drives the threaded rod to rotate, and the threaded frame moves along the sliding groove on the inner side of the load-bearing plate, so that the positions of the first clamping plate and the second clamping plate can move left and right, thereby moving the loose low-voltage cable around the winding roller. The low-voltage cable is not easy to get tangled. The first hydraulic cylinder pushes the push plate, which, together with the sliding plate, slides in the limiting groove of the connecting plate, so that the first clamping plate and the second clamping plate can move back and forth. It is suitable for winding rollers of different lengths, so that the cable can be accurately pushed to the designated position.

[0039] Example 3

[0040] Please see Figure 1-6 Furthermore, based on Embodiment 1, the take-up mechanism 3 includes a support plate 32, which is fixedly connected to the bottom of the load-bearing plate 5. A second hydraulic cylinder 33 is fixedly connected to the front of the support plate 32, and a push plate 31 is fixedly connected to the back of the second hydraulic cylinder 33. A linkage plate 38 is fixedly connected to the top of the push plate 31, and a moving plate 37 is fixedly connected to the inner side of the linkage plate 38. A rotating disk 303 is rotatably connected to the inner side of the moving plate 37. A winding roller 36 is inserted into the inner side of the rotating disk 303. A worm gear 302 is inserted into the front side of the winding roller 36. A mounting plate 34 is rotatably connected to the back end of the worm gear 302. The mounting plate 34 is fixedly connected to the top front of the load-bearing plate 5. A worm 301 is meshed at the bottom of the worm gear 302. A connecting frame 35 is rotatably connected to the periphery of the worm 301. The connecting frame 35 is fixedly connected to the front of the mounting plate 34. A rotating motor 39 is fixedly connected to the right side of the worm 301. The rotating motor 39 is fixedly connected to the right side of the connecting frame 35.

[0041] Furthermore, a sliding groove corresponding to the movement trajectory of the linkage plate 38 is provided on the top left side of the load-bearing plate 5, and the linkage plate 38 is slidably connected inside the sliding groove. By opening the sliding groove, the push plate 31 can be moved, which can drive the moving plate 37 to move through the linkage plate 38, so that the position of the moving plate 37 can be adjusted, and the device can limit the winding roller 36 of low voltage cables of different lengths.

[0042] In actual operation, when this device is used, the front of the winding roller 36 is inserted into the worm gear 302. The operator manually opens the second hydraulic cylinder 33, which drives the linkage plate 38 to move through the push plate 31. The linkage plate 38 can drive the rotating disk 303 to move forward through the moving plate 37, so that the rotating disk 303 can be inserted into the outer periphery of the back end of the winding roller 36. The operator manually opens the first hydraulic cylinder 416, which drives the push plate 418 and the sliding plate 419 to move, so that the sliding plate 419 can move to the middle position on the right side of the winding roller 36.

[0043] Turn on the rotating motor 39, which drives the worm gear 302 to rotate via the worm 301. The worm gear 302 then drives the winding roller 36 to rotate slowly, allowing the low-voltage cable around the winding roller 36 to be pulled by the operator. The operator manually pulls the pull plate 427, which moves the second clamping plate 424 via the slide rod 425, moving the second clamping plate 424 away from the first clamping plate 422. The low-voltage cable is then passed between the first clamping plate 422 and the second clamping plate 424. The force on the pull plate 427 is released, and the elastic force of the spring 426 allows the slide rod 425 to move the second clamping plate 424. The second clamping plate 424 works in conjunction with the first clamping plate 422 to provide auxiliary clamping for the low-voltage cable, making the cable more stable during the pulling process.

[0044] When the low-voltage cable near the winding roller 36 is in a slack state, the operator manually turns on the drive motor 411 switch, so that the drive motor 411 drives the threaded frame 414 to move through the threaded rod 413, and the threaded frame 414 drives the first clamping plate 422 and the second clamping plate 424 to move through the connecting plate 415, so that the first clamping plate 422 and the second clamping plate 424 can pull the low-voltage cable to move, so that the low-voltage cable is in a taut state, and the low-voltage cable is not easy to get tangled when it is pulled.

[0045] When the low-voltage cables are not in use and need to be retrieved, the staff manually turns on the rotating motor 39, which drives the worm gear 301 to rotate the worm wheel 302 in the opposite direction. The worm wheel 302 then drives the winding roller 36 to rotate, retrieving the excess low-voltage cables for future use.

[0046] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
