Municipal engineering cable insertion device

Abstract

The invention relates to the field of municipal engineering, and aims to provide a municipal engineering cable insertion device. The device comprises a bottom plate, a lifting groove is formed in the outer wall of the top of the bottom plate, a supporting frame is welded to the position, close to the lifting groove, of the outer wall of the top of the bottom plate, and a lifting motor is installed on the outer wall of the top of the supporting frame through screws; a lead screw is fixedly installed at the output end of the lifting motor through a coupler, the exterior of the lead screw is in threaded connection with a lifting mechanism, and the lifting mechanism is slidably connected into the supporting frame; and the lifting mechanism comprises a lifting frame, and a screw hole is formed in the outer wall of the top of the lifting frame. The device has the beneficial effects that through the arranged lifting mechanism, the lifting frame of the lifting mechanism can be driven by the lifting motor to automatically go deep into a well during use, and a cable is guided through a first reversing roller and a second reversing roller, so that friction between the cable and an underground turning point can be effectively prevented, an operator does not need to manually place the device underground, and the device is convenient to use.

Description

technical field [0001] The invention relates to the field of municipal engineering, in particular to a municipal engineering cable insertion device. Background technique [0002] Cable construction is very common in municipal engineering. The usual practice is that one to three people grab the cable extension and stretch it outward after the cable protrudes from the well. During the stretching process, due to the end of the pipe and the inner wall of the inspection well The place is usually a sharp corner, so there will be a large frictional resistance. To overcome this frictional force, more people need to participate in the stretching to pull the cable out. In addition, the cable skin is often scratched, which affects its performance. and safety performance. [0003] Chinese Patent No. CN107221884B provides an auxiliary device for interspersed cables in municipal engineering, including a base plate, universal wheels are provided at the four corners of the bottom of the ba...

Problems solved by technology

[0004] The existing cable penetration device can generally guide the cable after the cable is threaded into the cable well to avoid contact between the cable and the edge of the cable well. However, the wellhead of the cable well is generally small, and the underground space is large. , so there will be two turning friction points in the process of cable threading, downhole and uphole, and a cable penetration bracket for municipal engineering can only solve the friction point above the well, but cannot solve the friction point downhole; Although the device can solve the two turning friction points of downhole and uphole, it needs to be placed downhole, which is inconvenient to use
