Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to the laying of cables, and specifically is a height-adjustable shock-absorbing cable tube bracket. Background Art

[0002] In the prior art, with the rapid development of underground laying of power cables, higher requirements have been put forward for cable casings, which are suitable for the fields of telecommunications, power engineering, transportation, urban construction, etc. There are generally two types of casings: steel protective pipes, which are divided into thin-walled pipes and thick-walled pipes, and galvanized and non-galvanized. Plastic pipes, which are generally made of polyvinyl chloride plastic or U-PVC, are available in ordinary and flame-retardant types, are cheaper than metal pipes, are easy to construct, and will not rust. Most of the wire threading sheaths are made of plastic pipes.

[0003] At present, during the installation of cables, the cables are laid axially in cable protection tubes, and tube supports are used to support the cables and cable protection tubes. The shortcomings of existing cable tube supports are that they are all rigid fixed structures, and the height of the cable tube support points cannot be adaptively adjusted according to the direction of the cable. At the same time, they do not have seismic resistance. During vibration, the cable tube support points are easily damaged, thereby affecting the normal use of the cable. Summary of the invention

[0004] The utility model aims to solve the problems existing in the above-mentioned prior art and to provide a height-adjustable shock-absorbing cable tube bracket.

[0005] The utility model is realized through the following technical solutions:

[0006] A height-adjustable shock-absorbing cable tube bracket comprises a base and a clamp; two fixed screws arranged at intervals are vertically fixed on the base, and a compression spring is sleeved on each fixed screw; the clamp comprises an upper hoop body and a lower hoop body butted against each other, one end of the upper hoop body and the lower hoop body are hingedly connected, and the other end is detachably connected by a fastening bolt, and collars are respectively connected and fixed at both ends of the lower hoop body, and the two collars are respectively sleeved on two fixed screws, and the compression spring is placed between the base and the collar; an adjusting nut is threadedly connected to each fixed screw, and the adjusting nut is clamped on the top of the collar.

[0007] Furthermore, the fixing screw and the base are connected and fixed via a support rod, the lower rod section of the support rod is fixedly connected to the base, and the upper rod section is threadedly connected to the fixing screw.

[0008] Furthermore, the support rods adopt expansion bolts.

[0009] Furthermore, the upper hoop body and the lower hoop body are both C-shaped hoop bodies, and the two are butt-jointed to form a circular clamp.

[0010] Furthermore, the top ends of the two fixing screws are sequentially connected to a plurality of pairs of fixing screws from bottom to top through threaded sleeves, and each pair of fixing screws is also connected to a compression spring, a clamp, a collar and an adjusting nut.

[0011] The utility model has a scientific design, reasonable structure, simple manufacture and convenient use. The cable tube support point in the bracket can be adjusted up and down by adjusting the nut, thereby achieving the purpose of freely adjusting the height of the bracket according to the height of the cable direction, and improving the application range of the bracket. At the same time, due to the setting of the compression spring, the cable tube support point in the bracket becomes a flexible support. On the one hand, this can further fine-tune the position according to the direction of the cable, and on the other hand, it also enhances the anti-seismic performance of the bracket. When encountering strong vibrations, the cable tube support point can vibrate flexibly, protecting the cable tube from damage, and ensuring the normal and orderly progress of the entire project.
