The invention discloses an assistant tool for fastening a screw of a transmission line tower. The assistant tool is characterized by comprising a connecting bar rotating sleeve (1) which consists of a first connecting loop bar (7) and a second connecting loop bar (8), wherein the first connecting loop bar (7) is formed by connecting a first connecting bar body (7-1) and a quincuncial socket (7-2); the second connecting loop bar (8) is formed by connecting a second connecting bar body (8-1) and a double-ring sleeve (8-2); the double-ring sleeve (8-2) sleeves the quincuncial socket (7-2); the connecting bar bodies are correspondingly connected with threaded sleeves, and each threaded sleeve (2) is in thread connection with one end of the corresponding connecting bar; the other end of each connecting bar is connected with a connecting bar sleeve ring (5); a clockwise-counterclockwise rotation switching controller (6) is arranged on each connecting bar sleeve ring (5); a ratchet wheel (4) is embedded into the each connecting bar sleeve ring (5); threads in the tail end of each connecting bar body are in the direction opposite to that of the threads in one end of the corresponding connecting bar. The assistant tool for fastening the screw of the transmission line tower is reasonable in structure, and convenient to operate, and can save both time and force; the screw can be quickly and effectively fastened through the assistant tool, so that the risk of working at heights can be reduced, the working efficiency can be improved, and the power supplying reliability can be improved.
Description
Technical field: [0001] The invention relates to an auxiliary tool for fastening screws of transmission poles and towers, which belongs to the field of power system transmission line maintenance. Background technique: [0002] The assembly and maintenance of transmission line towers require repetitive screw fastening work. In the process of screw fastening, it often occurs that the bolt of the screw rotates together with the nut and cannot continue to be tightened. During the erection and maintenance of transmission line poles and towers, the screws on the main bars of the poles and towers are arranged in two or more rows in a regular shape, and the number of screws on a single main connection part can reach 40-50, which is labor-intensive and takes a long time. At present, generally adopt two wrenches to realize the fastening of screws, one wrench fixes the head of the bolt, and the other wrench tightens the nut, which is very inconvenient for workers working at heights. ...
