Portable wire harness tightening tool for electric power circuit laying

Abstract

The invention relates to a portable wire harness tightening tool for electric power circuit laying. The portable wire harness tightening tool comprises a lifting device, a clamping device and a rotating device. The lifting device is installed at the lower end of the clamping device. The rotating device is installed at the lower end of the lifting device. The problems that when a drooping cable istightened, generally manual operation is needed, the cable cannot be too loose or too tight when tightened and needs to be tightened with great strength, the cable may be broken when being excessivelytightened, power transmission is affected, personal safety of an operator is greatly threatened, a traditional machine mechanically drives a winding roller through power to rotate so as to tighten the cable, a worker not only needs to straighten the cable by rotating a wheel in the operation process, but also needs to continuously prevent the wheel from rotating backwards with strength under thecounteracting force of the cable, and great inconvenience is brought to the worker can be solved.

Description

technical field [0001] The invention relates to the field of power transmission, in particular to a convenient wire harness tightening tool for laying power lines. Background technique [0002] With the development of our country's economy, our country's demand for energy is also increasing. The power grid has spread all over the country, but the power needs to rely on cables in the process of transmission. The cables are fixed on the poles. After a period of time, the cables It is easy to loosen and give people a sense of visual insecurity. In recent years, accidents causing casualties due to sagging cables have occurred frequently. The sagging cables have affected the travel safety of residents. If the sagging cables are damaged, accidents may occur, threatening people’s health. Safety of life, the cable needs to be tensioned after the cable sags so that the cable will no longer sag. [0003] However, there are the following problems in tensioning the drooping cables at p...

Problems solved by technology

[0002] With the development of our country's economy, our country's demand for energy is also increasing. The power grid has spread all over the country, but the power needs to rely on cables in the process of transmission. The cables are fixed on the poles. After a period of time, the cables It is easy to loosen and give people a sense of visual insecurity. In recent years, accidents causing casualties due to sagging cables have occurred frequently. The sagging cables have affected the travel safety of residents. If the sagging cables are damaged, accidents may occur, threatening people’s health. Safety of life, the cable needs to be tensioned after the cable sags so that the cable does not sag anymore

[0003] However, there are the following problems in tensioning the drooping cables at present. First, when the drooping cables are tensioned, manual operations are generally required, and when the cables are tensioned, they should neither be too loose nor too tight, and a larger If the tension is too high, the cable may be broken, affecting the transmission of power and posing a great threat to the safety of the operator; 2. The traditional machine uses a power mechanism to drive the take-up roller to rotate and damage the cable. To tighten, during the operation, the worker not only needs to straighten the cable by rotating the roller, but also needs to continue to use force to prevent the roller from turning under the reaction force of the cable, which brings a lot of inconvenience to the worker
