Description

Technical Field

[0001] The utility model relates to a tensioning device, in particular to a power line tensioning device for power line release. Background Art

[0002] The wire is composed of one or more soft conductors, which are wrapped with a light and soft sheath. The wire is generally composed of three components: a core wire, an insulating layer and a protective layer. When the wire is in use, it is initially wound on a winding wheel. When the wire is released, it is easy to become loose, which makes the wire inconvenient to use or collect, and then the wire needs to be tightened. The existing tensioning device is generally tightened at a fixed position and cannot be moved, which is inconvenient for on-site operations. When the wire is released, the operating height of the wire is not the same. If the outlet position is fixed when the wire is released, the wire often gets stuck.

[0003] How to design a power line tensioning device for electric line release with a movable tensioning position has become a problem to be solved at present. Utility Model Content

[0004] In order to overcome the disadvantage that the tensioning device is fixed in position and the line is stuck when releasing the line, the utility model aims to solve the technical problem of providing a power line tensioning device for electric line release with a movable tensioning position.

[0005] In order to solve the above technical problems, the utility model provides a power line tensioning device for power line release, comprising a frame, a winding drum, a rotating shaft, a first mounting frame, a motor, a second mounting frame, a first mounting plate, a sliding frame, a fixed ring, a fixed block, a first guide rod and a first screw. A winding drum is arranged in the frame, a first mounting frame is installed at the bottom of the frame, a motor is installed on the first mounting frame, an output shaft of the motor is connected to the rotating shaft through a coupling, a second mounting frame is arranged on one side of the winding drum, a first mounting plate is installed in the middle of the second mounting frame, a sliding frame is slidably arranged in the middle of the first mounting plate, a fixed ring is installed on the sliding frame, a fixed block is movably arranged in the sliding frame, a first guide rod is slidably penetrated through the bottom of the sliding frame, the first guide rod is fixedly connected to the bottom of the fixed block, a first screw is threadedly penetrated through the bottom of the sliding frame, and the first screw is connected to the bottom of the fixed block.

[0006] Preferably, it also includes a second screw, a second guide rod and a lifting block. The second screw is installed on the side of the winding drum close to the second mounting frame, and the second guide rod is installed on the other side of the winding drum close to the second mounting frame. Lifting blocks are fixedly connected to both sides of the second mounting frame. The second guide rod slides through the lifting block, and the lifting block is threadedly connected to the second screw.

[0007] Preferably, a third mounting plate is further included, and the third mounting plates are symmetrically mounted on both sides of the bottom of the rack.

[0008] Preferably, a universal wheel is also included, and the universal wheel is installed at the bottom of the third mounting plate.

[0009] Preferably, an anti-skid pad is also included, and the anti-skid pad is pasted on the side of the fixing ring close to the fixing block.

[0010] Beneficial effect: When the wire needs to be tightened, the first screw is rotated, and the fixed block slides along the sliding frame to clamp the wire between the fixed ring and the fixed block, so that the position of tightening the wire can be moved. BRIEF DESCRIPTION OF THE DRAWINGS
