Description
Technical field
The present invention relates to cable laying device, more particularly, to a kind of support meanss for installing cable, in addition, also relate to
And the installation method of this kind of cable support device.
Background technology
Cable is used for transmitting electric power or information, is the main ingredient of modern circuit configurations, especially in business or work
The electricity consumption close quarters such as industry, need to install a large amount of cables to ensure the normal conveying powered or communicate.
In order to ensure cable energy normal work, stress and the deformation of cable must be reduced when cable is installed as far as possible, and pacify
Assembling structure should be economical and practical.
If number of cables is more, cable testing bridge can be laid and be used for supporting cable, according to line arrangement design and reality electricity
The installation trend of cable, after cable testing bridge installation, then by cable laying on cable testing bridge, so, cable stress is less, and
Self-deformation amount is little, is easy to ensure the service life of cable.
When number of cables is less, installed according to cable testing bridge, then installation cost is big；Enter according to common wire clamp
Row is fixed, and because each wire clamp need to be fixed by steel nail, then workload when installing is big, and can break for fixing steel nail
Bad building or the aesthetic feeling of other fixations.
In order to be fixed to the cable of negligible amounts, people develop, design and be manufactured that different types of cable props up
Frame, cable bearer can increase the area of cable supporting surface when fixing, thus reducing the pressure of cable, reduces the change of cable
Shape, and then the safe service life of cable is effectively ensured.Typically first fix cable bearer during installation, then cable one end is passed through electricity
Cable support and along arranged direction stretching sequentially pass through each cable bearer thus installing to cable.
Notification number is that the Chinese utility model patent of CN202140692 U discloses a kind of low-voltage return wire fixed support, bag
Include two spool intermediate plates, the two ends of described two intermediate plates are all connected by fastening bolt, the back of one of which spool intermediate plate sets
It is equipped with fixing connecting rod, be provided with fixed seat in the end of fixing connecting rod.During installation, spool intermediate plate is stuck in certain being fixed cable
At individual position, pass through the two ends of spool intermediate plate with two fastening bolts and so that two spool intermediate plates is fixed as one, finally by
Spool intermediate plate is fixed at reserved position fixed seat.
The cable stationary barrier that above-mentioned utility model provides is although structure is relatively simple, but need to tighten two when being fixed
Individual clamping screw, time-consuming for installation, leads to inefficiency.
