Description

Technical Field

[0001] This utility model relates to the field of cable fixing, and in particular to a tower crane cable fixing device. Background Technology

[0002] Currently, Chinese utility model patent CN220950922U discloses a tower crane cable fixing device. While this device can clamp the cable with pressure plates to prevent it from falling off, it has other problems during use. For example, it lacks a strong magnetic quick-release function, and the device base is usually fixed to the tower crane steel structure with screws. Although this is stable and reliable, it is time-consuming and labor-intensive to install and remove, making it unsuitable for construction scenarios requiring frequent adjustments to cable layout. Furthermore, it lacks spacing adjustment functionality, and the protruding position of the fixing components is fixed after installation. When the cable hangs down from above and there is a difference in distance from the fixing components, the cable can only be bent and pushed into the fixing components, which can easily damage the cable's surface sheath, resulting in low flexibility. To solve these problems, we propose a tower crane cable fixing device. Utility Model Content

[0003] The purpose of this utility model is to provide a tower crane cable fixing device that solves the problems of existing fixing devices not having a strong magnetic quick-release function and not having a spacing adjustment function.

[0006] The present invention is further configured such that: the fixing mechanism includes a fixing frame, the fixing frame is bolted to the top of the fixing frame, the fixing frame has a fixing seat bolted to the fixing frame inside, the top of the fixing frame is threadedly connected to a first screw, and the bottom end of the first screw is rotatably connected to a pressure plate through a bearing.

[0007] By adopting the above technical solution, the cable placed in the arc groove of the fixing seat can be fixed by setting up the fixing frame, fixing seat, first screw and pressure plate, and preventing the cable from slipping out of the arc groove inside the fixing seat.

[0008] The present invention is further configured such that a through hole is provided on the back of the cast iron base.

[0009] By adopting the above technical solution, through the setting of the through hole, a tool can be inserted from the rear to push the permanent magnet out of the cast iron base.

[0010] The present invention is further configured such that: the other end of the connecting rod extends through to the outside of the baffle and is equipped with a rotating plate.

[0011] By adopting the above technical solution, the rotating plate allows personnel to easily rotate the permanent magnet by manually driving the connecting rod and the insert plate.

[0012] The present invention is further configured such that a spring washer is slidably sleeved on the surface of the second screw.

[0013] By adopting the above technical solution and setting the spring washer, the fixing effect of the nut after tightening can be improved, and it can play a role in shock prevention and loosening prevention.

[0014] The present invention is further configured such that: a guide rod is symmetrically welded to the top of the pressure plate, and the other end of the guide rod passes through and extends to the top of the fixing frame.

[0015] By adopting the above technical solution, the guide rod can limit the pressure plate and prevent it from rotating during the up and down movement.

[0016] The present invention is further configured such that rubber pads are bolted to the bottom of the pressure plate and the arc-shaped groove inside the fixing seat.

[0017] By adopting the above technical solution, the installation of rubber pads can protect the cable sheath and prevent scratches from being caused to the sheath when clamped.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. This utility model involves first placing the device next to the steel structure of the tower crane, then attaching the bottom of the cast iron base to the steel structure and manually rotating the rotating plate. The rotation of the plate will cause the permanent magnet to rotate. After the permanent magnet rotates, the south and north poles of the permanent magnet will be reversed, generating magnetic force. Once the magnetic force is formed, the cast iron base will be attracted to the steel structure. When removing it, simply continue to rotate the plate to reverse the permanent magnet again. It has a strong magnetic quick-release function, which can facilitate personnel to quickly change the installation position, eliminate the burden of temporary drilling of the steel structure, and improve work efficiency.

[0020] 2. This utility model allows for easy and convenient operation when a cable droops and cannot enter the fixing frame. By using your hand or a tool to loosen the nut, the fixing frame is released. Then, by pulling the fixing frame outward, the fixing seat moves outward along with the fixing frame. Once the fixing seat has moved to the appropriate distance, the nut is tightened again. This design provides a spacing adjustment function, is simple and convenient to operate, improves the fixing effect of the cable, and is highly practical. Attached Figure Description
