Description

Height-adjustable cable support for electric power design Technical Field The invention relates to the technical field of power engineering, in particular to a height-adjustable cable support for power design. Background In the power system construction and maintenance process, cable laying is a basic and key construction link. In order to ensure that the cable is orderly routed and uniformly stressed, and avoid the influence on the transmission safety caused by mopping, excessive bending or external force damage, a cable support is usually required to temporarily support the cable. The traditional cable support is of a fixed-height structure, the supporting height of the traditional cable support is not adjustable, the traditional cable support is difficult to adapt to diversified requirements of different construction environments on the cable laying height, and secondly, when cables of different specifications are faced, the traditional cable support lacks an effective clamping and limiting mechanism, so that the cables are easy to slide, deviate and even fall off, the construction quality is influenced, and safety accidents are possibly caused. In order to solve the problems, the hydraulic lifting or electric push rod structure is introduced into the bracket on the market at present, however, the device depends on an external power supply or a hydraulic system, has limited applicability in complex or power-free operation environments such as the field, a tunnel, a transformer substation and the like, has complex structure and higher cost, and has risks of oil leakage, motor failure, control failure and the like, and serious potential safety hazards. Disclosure of Invention The invention aims to solve the technical problems and provide the technical task of perfecting and improving the prior art scheme, and provides the height-adjustable cable support for electric power design, so as to achieve the purpose of conveniently adjusting the fixing and supporting heights of cables with different specifications.
