Description

Technical Field

[0001] The utility model relates to the technical field of subway construction tools, in particular to a subway construction pipeline hanging device. Background Art

[0002] Power cables are a type of subway pipeline. During subway construction, they are used to supply power to subway construction tools, platform lighting, ventilation equipment and other facilities. These power cables carry high voltage and high current to ensure the normal operation of subway construction. During construction, power cables usually need to be suspended so that they can transmit electricity without affecting subway construction.

[0003] However, the existing power cable pipelines are usually installed in a fixed manner during subway construction. Since the fixed installation method is usually a one-time installation, the cable pipelines cannot be flexibly installed and disassembled. At the same time, the installation height of the cable pipeline cannot be flexibly adjusted, which has a certain impact on the use of the cable pipeline. Therefore, a subway construction pipeline suspension device is proposed;

[0004] To this end, this case proposes a subway construction pipeline suspension device to address the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a subway construction pipeline suspension device, which can effectively solve the technical problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A subway construction pipeline suspension device comprises a collar, an annular groove is provided on the inner side of the collar, a gear ring is arranged in the annular groove, a gear is arranged on the inner side of the collar, and the gear is meshed with the outer side of the gear ring, a turning handle is fixedly installed at the center position of the outer side of the gear, and the turning handle and the collar are movably connected.

[0008] As a further solution of the utility model, a thread groove is opened through the outside of the collar and the gear ring, a bolt is arranged in the thread groove, and the collar is connected to the gear ring through the bolt and the thread groove.

[0009] As a further solution of the utility model, a sleeve rod is fixedly installed on the top of the sleeve ring, and a connecting rod is sleeved on the outside of the sleeve rod.

[0010] As a further solution of the utility model, a movable groove is opened through the front part of the connecting rod, an insertion rod is inserted into the movable groove, and an insertion block is arranged at the end of the insertion rod.

[0011] As a further solution of the utility model, a spring is arranged outside the insertion rod, one end of the spring is fixedly connected to the connecting rod, and the other end of the spring is fixedly connected to the insertion block.

[0012] As a further solution of the utility model, the rear portion of the insert block is provided with an inclined surface, and a plurality of slots matching the insert block are provided on the outside of the sleeve rod.

[0013] As a further solution of the utility model, a connecting plate is fixedly installed on the top of the connecting rod, and a plurality of installation grooves are opened through the upper and lower parts of the connecting plate.

[0014] The beneficial effects of the utility model are as follows:

[0015] By setting the gear ring and the gear matching the sleeve ring, the installation and removal of the cable pipeline are more convenient. When installing the cable pipeline, the gear rotates by turning the handle, and the gear rotates, and the rotation of the gear drives the meshing gear ring to rotate, and one end of the gear ring will be inserted into the sleeve ring. When the gear ring cannot rotate, the sleeve ring and the thread groove of the gear ring are aligned, and then the bolt is inserted into the thread groove to fix it. When disassembling, it is only necessary to remove the bolt, turn the handle, and then take out the cable pipeline, so that the cable can be installed flexibly, and the situation that the cable pipeline is inconvenient to disassemble due to being fixedly installed can be avoided;

[0016] By arranging an insertion rod, an insertion block, a spring, a slot, a sleeve rod and a connecting rod, the height of the device can be flexibly adjusted. When in use, the insertion rod is pulled, the spring contracts, and the insertion block also contracts into the movable slot. Then the sleeve rod is pulled out or contracted. After the length of the sleeve rod is adjusted to a suitable position, the pull rod is released, and the spring resets to drive the insertion block to pop out and insert it into the slot. In this way, the height of the cable pipeline installation can be flexibly adjusted, which is more practical. BRIEF DESCRIPTION OF THE DRAWINGS
