Description

TECHNICAL FIELD

[0001] The utility model belongs to the transmission line stringing technical field, concretely relates to a construction pulley for transmission line stringing. BACKGROUND

However, the connecting frame of the cable pulley on the market is usually in U-shaped structure, when the power cable is connected with the cable pulley, the staff needs to pass the power cable through the connecting frame, which will cause great inconvenience when the power cable is connected with the cable pulley. Since the connecting frame of the cable pulley is in U-shaped structure, the pulley and the connecting frame can form a rectangular structure, when the cable pulley pulls the power cable, it is not convenient for the staff to separate the pulled power cable from the cable pulley, which will cause great inconvenience when the cable pulley is disassembled. At the same time, the connecting frame on the existing cable pulley usually needs to be fixed with external equipment by bolts, when used on some stone wall, there will be gaps between the stones in the stone wall, which are not convenient for installing bolts, which will cause the connecting frame of the cable pulley to be inconveniently fixed with the stone wall.

After the end of the upper insertion piece and the end of the lower insertion piece are inserted into the gap of the stone wall, the repulsive force generated by the extrusion spring drives the end of the upper insertion piece to separate, achieving the effect of maintaining overall stability.

[0004] However, there is a large gap between the end of the upper insertion piece and the end of the lower insertion piece in the above technology, which causes the requirement for the gap width of the stone wall when they are inserted into the gap of the stone wall, and it is difficult to determine the insertion position in practice.
