Description

A kind of novel multifunctional cable bracket

Technical field

The utility model belongs to power cable construction equipment field, and in particular to a kind of novel multifunctional cable bracket.

Background technique

With Nanning City's socio-economic development and intelligent urban construction, regional international big city positioning requirements are created, Also to Construction of Intercity Network, more stringent requirements are proposed for city appearance and beautification work, and the chemical conversion of power overhead network cable underground is The trend of the times of Construction of Intercity Network.Power circuit pushes cable undergroundization that can improve equipment operating environment, improves city and supplies Electric reliability promotes power equipment and beautifying city landscape while enhancing power supply capacity.As urban development power construction is used Ground is more and more limited, and cable undergroundization usually using both sides of the road greening and pavement plot, is laid in cable duct and tunnel. Since the underground utilities such as both sides of the road communication, combustion gas are numerous, it is limited to that channel space is limited, and cable shaft is very narrow, cable applies And if difficulty of construction is all difficult, cable is generally fixed using bracket power cable all the time, conveniently recognized and avoid electricity Cable winding when being laid with is entangled with, therefore more stringent requirements are proposed for the performance of cable bearer, need to have certain intensity, Fire prevention, corrosion resistant performance, and can adapt to different cable passages.Cable passage currently on the market is largely pre-buried Formula, it has fixed, can not change depending on the site environment.Pre-embedded cable bracket can hurt during payout, scratch Staff.Cable bearer is that fixation is welded, and causes construction in cable shaft, the limited space inner support of ditch and O&M is not in the future Just, it therefore needs to research and develop a kind of electric cable support that can solve the above problem, meets the requirement of distribution project construction.

Summary of the invention

The purpose of the utility model is to provide a kind of novel multifunctional cable bracket, realize that urban distribution network cable bearer is removable It is dynamic, foldable, the utilization rate and flexibility in buried cable channel are promoted, power system security production and construction are further pushed.

The purpose of the present invention is what is be achieved through the following technical solutions:

A kind of novel multifunctional cable bracket, including cable bearer, horizontal trailing arm (being commonly called as cross-arm), base；The cable Track is provided on bracket, base is flexibly connected in orbit；Horizontal trailing arm is movably connected in base；The horizontal trailing arm with Limiting card is provided with below base junction.Increase the load capacity of horizontal trailing arm, and its shaking can be prevented, plays firm make With.

The back of the cable bearer is provided with several fixing glues as a further improvement of the utility model,.Fixing glue For entire cable bearer to be fixed in cable shaft.

The base is a sliding block as a further improvement of the utility model, and the center of sliding block is provided with convex block, water Arm is lifted to be flexibly connected with convex block.
