Description

Technical Field

[0001] The present invention relates to the field of auxiliary communication installation, and particularly relates to an auxiliary device facilitating communication installation. Background Art

[0002] Communication cables are usually composed of a cable core, a sheath and a protective layer. According to the different structures of the cable core, they can be divided into symmetrical cables and coaxial cables. In the former, the mutually insulated wires in the cable core adopt the structural form of two-wire pairs twisted into groups or four-wire star-twisted into groups, and in the latter, the cylindrical inner and outer conductors are coaxially sleeved with each other and insulated from each other. If there are both symmetrical wire pairs and coaxial tubes in the cable core, it is called a composite cable. Communication optical cables are usually composed of several optical fibers, reinforcing members, etc. Compared with cable communication, optical fiber communication has the advantages of large communication capacity, small volume, light weight, anti-interference, strong confidentiality and saving non-ferrous metals.

[0003] When installing these cables, a cable trough will be embedded first, and then the cables will be installed into it. It is relatively convenient to install in places where people can reach, but it is still not possible to install quickly, and it is very troublesome in places such as ceilings at higher positions. Therefore, we have designed an auxiliary device facilitating communication installation. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, meet the actual needs, and provide an auxiliary device facilitating communication installation.

[0005] To achieve the purpose of the present invention, the technical solution adopted by the present invention is: an auxiliary device facilitating communication installation, including a pushing trolley and installation rollers. An annular wiring groove is arranged on the circular arc surface of the installation rollers. The main body of the pushing trolley is in a rectangular plate-like structure, and there are two pairs of pushing wheels arranged around it; a support column is arranged above the middle of the pushing trolley, and an installation roller is arranged above the support column. Vertical plates are rotatably arranged on both sides of the installation roller, and a cross plate is arranged at the bottom of the two vertical plates. The middle of the bottom of the cross plate is fixedly connected to the upper end of the support column. A wire reel is arranged at the front end of the pushing trolley for pushing and installing cables. One side of the wire reel is rotatably arranged on a support plate, and the support plate is fixed on the pushing trolley. The cable of the wire reel is limited on the wiring groove for pushing and wiring.

[0006] The tires of the pushing wheels are pneumatic tires.

[0007] The support column includes a fixed column and a movable column. A cavity is arranged inside the fixed column, and a telescopic opening with a diameter smaller than the inner diameter of the cavity is arranged at the upper end of the fixed column. The lower end of the movable column extends into the fixed column from the telescopic opening and is limited to move up and down inside the fixed column.

[0008] Inside the cavity of the fixed column, there is a spring tube that fits it and can move up and down. The main body of the spring tube is a cylindrical closed tube structure. There is an opening above the spring tube with the same diameter as the telescopic opening. The movable column extends into the spring tube from the opening. A piston block is provided at the end of the movable column that extends into the spring tube. The piston block fits the spring tube. A spring is sleeved outside the movable column between the piston block and the opening. The fixed column is vertically arrayed with horizontally penetrating jacks. At the position corresponding to the jacks of the fixed column at the bottom of the spring tube, there are jacks. After setting the position of the spring tube, the spring tube is limited by inserting pins into the fixed column and the spring tube.

[0009] On the side of the installation roller close to the installation cable, there is an auxiliary wheel. The diameter of the auxiliary wheel is smaller than that of the installation roller. The arc surface of the auxiliary wheel is provided with an auxiliary groove having the same shape as the installation roller. The installation roller and the auxiliary wheel fit together, and the height of the auxiliary wheel is lower than that of the installation roller.

[0010] The beneficial effects of the present invention are as follows:

[0011] According to different height scenarios, set the position of the spring tube and fix it with pins. When the installation roller is rolling and wiring, the spring of the spring tube can adapt to the terrain fluctuations of the top wall part of the wiring loop, combining rigid connection and ordinary spring connection. It can not only be suitable for installations at different heights but also take into account terrain fluctuations, thus better meeting various installation environments. Description of the Drawings
