Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction, in particular to a height-adjustable cable pay-off rack for electric power construction. Background Art

[0002] In the cable laying of various projects, the cables are usually wound on cable drums. The cables are laid out from the cable drums. In order to ensure that the cables are straight during the laying process, the cable drums need to be placed on the pay-off racks to lay the cables. Most cable drums are heavy and cannot be moved for laying. Usually, the cable drums are lifted by hoisting machinery before laying the cables.

[0003] When workers are carrying out power construction, sometimes the area for laying cables is small and the hoisting machine cannot be used, so a cable pay-off rack is used for construction. However, the existing cable pay-off rack cannot adjust its height during construction. When workers are laying cables at a higher position, the cable pay-off rack is low, which causes the workers to use greater force to pull the cables for laying. This is inconvenient and also poses a safety hazard.

Two guide grooves are provided on the inner sides of the two guide bases 10, and the four guide metal blocks 9 are slidably installed in the corresponding guide grooves respectively. Two clamping clips 12 are fixedly installed on the top of the corresponding lifting columns 8, so that the corresponding clamping clips 12 can be driven to rise and fall by the lifting and falling of the two lifting columns 8.

[0025] In this embodiment, a driving shell 2 is fixedly installed on the top of the bracket base 1, and a dual-axis motor 3 is fixedly installed on the bottom inner wall of the driving shell 2. The two output shafts of the dual-axis motor 3 are respectively fixedly connected to the corresponding worm gears 5, and the two worm gears 5 can be driven to rotate by the dual-axis motor 3.

[0026] In this embodiment, a fixed shell 13 is slidably installed on the inner side of the two clamping clips 12. The fixed shell 13 on the right side is rotatably connected to the main shaft 16, and the fixed shell 13 on the other side is detachably connected to the main shaft 16. A motor slot is opened inside the fixed shell 13 on the right side, and a servo motor 15 is fixedly installed on the bottom inner wall of the motor slot.

Two grooves are provided on the outer side of the main shaft 16, and the two grooves are respectively matched with the corresponding protrusions, so that the main shaft 16 can drive the cable drum 17 to rotate.

[0029] Working principle: When in use, the staff pushes the cable drum 17 to the specified position of the bracket base 1, passes the main shaft 16 through the rotating hole 18 on one side of the cable drum 17, installs the fixed shell 13 with it, passes the two fixed shells 13 through the gaps of the corresponding clamping clips 12 respectively, aligns the positioning holes on the two fixed metal blocks 14 with the fixing holes on the two clamping clips 12, and then fixes and connects them with bolts to complete the assembly.
