Description

Technical Field

[0001] The utility model relates to the technical field of wire-paying racks, in particular to a wire-paying rack for electric power engineering. Background Art

[0002] Power engineering construction refers to the actual construction work carried out when building, renovating and expanding power system facilities. Its purpose is to enable the power system to operate normally and provide effective power supply. Power engineering construction mainly includes the following aspects: Design: formulate power engineering design plan, determine the specific construction content and objectives of the project; Preparation: carry out preparatory work before power construction, including site selection, environmental impact assessment, fundraising, etc.; Construction: carry out actual construction work in accordance with the power construction design plan, including the laying of power lines, construction of substations, etc.; Commissioning: perform performance testing and commissioning of the built facilities to ensure their normal operation; Acceptance: complete the project acceptance procedures to ensure the safety, reliability, economy, etc. of power facilities.

[0003] During the construction process, a cable pay-off rack is often used. The specific operation is that when placing the cable drum, the middle part of the cable drum needs to be manually inserted into the fixed shaft. Then, the cable drum needs to be lifted by a forklift or other means, and the two ends of the rotating shaft need to be inserted into the corresponding plug-in parts of the cable pay-off rack, so that there is a distance between the drum and the ground, which is convenient for placing or retracting the cable.

[0004] However, we found in actual use that the existing pay-off stand will rotate the cable drum to achieve cable retraction and release during use. However, during the rotation process, the drum may gradually shift to one side of the fixed axis due to uneven cable reeling, thereby affecting the stable operation of the pay-off stand and posing certain safety hazards. For this reason, we propose a pay-off stand for power engineering. Utility Model Content

[0035] A synchronous shift unit 4, wherein two synchronous shift units 4 are provided, and the two synchronous shift units 4 are respectively provided on opposite sides of the two frames 1, and are used to position the cable barrel 3 to prevent it from shifting when rotating;

[0036] The synchronous displacement unit 4 includes an installation box 41 arranged on the fixed rod 10, and a self-locking telescopic assembly 5 connected to the extrusion seat 9 is arranged in the installation box 41, which is used to drive the displacement adjustment of the extrusion seat 9 and the real-time self-locking positioning after the adjustment is completed;

[0037] The self-locking telescopic assembly 5 includes a rotating shaft 51 rotatably arranged on the installation box 41, one end of the rotating shaft 51 extends to the outside of the installation box 41, and a driving member 6 for driving the rotating shaft 51 to rotate is arranged on the rotating shaft 51. A displacement member 7 connected to the extrusion seat 9 is arranged in the installation box 41, and is used to drive the extrusion seat 9 to shift and adjust in the installation box 41.

Specifically, rotating the driving disk 61 drives the rotating shaft 51 to rotate, and the rotating shaft 51 drives the worm 82 to rotate, and the worm 82 drives the worm wheel 81 meshing therewith to rotate. Driven by the rotating shaft 74, the gear 75 rotates, driving the rack 73 and the sliding rod 72 to shift in the sliding frame 71, thereby pushing the extrusion seat 9 out until it stops after approaching the cable drum 3.

[0045] When in use, the staff installs the cable drum 3 together with the fixed shaft 2 in place, and then rotates the driving disk 61 from both sides to drive the fixed plate 91 and the movable plate 93 to shift inward to ensure that the cable drum 3 is located between the two frames 1. Specifically, rotating the driving disk 61 drives the rotating shaft 51 to rotate, and the rotating shaft 51 drives the worm 82 to rotate, and the worm 82 drives the worm wheel 81 meshing therewith to rotate. Driven by the rotating shaft 74, the gear 75 rotates, driving the rack 73 and the sliding rod 72 to shift in the sliding frame 71, thereby pushing out the fixed plate 91 and the movable plate 93 until the ball 94 fits the cable drum 3 and the spring 92 is not squeezed and deformed. When the cable drum 3 is offset, it will directly squeeze the ball 94 on that side, and then provide a reverse force to drive it to reset under the squeezing of the spring 92 on that side.
