Problems solved by technology

Its disadvantages are: 1) It is difficult to build a frame, and it is time-consuming and expensive
2) The removal of the above tools is time-consuming and labor-intensive
3) It is very difficult to dock the semicircular drainage tube at high altitude, which is time-consuming and labor-intensive, and the efficiency is extremely low
4) It is time-consuming and labor-intensive for the lead wire of the above tools to be injected into the self-target lock, and the operator needs to be at the upper end of the bracket to control the rope shooting robot at high altitude and the shooting accuracy is poor

Abstract

The invention discloses a high voltage power transmission and distribution cable road-crossing machine tool and a cable erecting method. The high voltage power transmission and distribution cable road-crossing machine tool includes a stay wire tension device, a laying tension mechanism, a quick tensioning mechanism, a lead ejection device, a cable pulling rope and at least two wire erecting brackets, wherein a lead and the cable pulling rope are sequentially connected with the cable through a mouse-type wire connector; each wire erecting bracket includes a base, an upright and a wire erecting cross rod. According to the invention, compared with the prior art that the tool needs at least 5 persons for cable erecting, while the machine tool provided by the invention only needs 2 operators and the time consumed is only one fourth of the time consumed in the prior art, more importantly, the lead, the pulling rope and the cable are suspended all the time, thereby not influencing road transportation at all.

Description

technical field [0001] The invention belongs to the technical field of high-voltage power transmission and transformation stringing equipment, and in particular relates to a high-voltage power transmission and distribution cable cross-road erection machine tool and a stringing method. Background technique [0002] With the development of the power grid, the reliability requirements of electrical equipment in the power system are getting higher and higher. The increase in the number of operations of power equipment due to power outages and restorations may lead to negative impacts on safety production and personal injury due to long power outages and fatigue operations in power transmission engineering installations. Therefore, in order to ensure the installation and construction quality of personnel operations, it is necessary to use scientific operation modes and new construction inspection methods to ensure personal safety and equipment operation reliability, so that when ...
