Description

Technical Field

[0001] The utility model relates to the technical field of municipal construction equipment, in particular to a municipal public municipal pipe well construction auxiliary device. Background Art

[0002] Municipal pipe well construction refers to a series of underground space excavation and backfilling engineering activities carried out in the process of urban planning, construction and renovation to meet the needs of underground pipeline installation, repair, renewal and expansion, so as to ensure the safety and normal operation of underground pipelines and protect surrounding buildings and underground facilities from damage;

[0003] It has been found in actual use that the existing municipal pipe well construction has the following deficiencies:

[0004] During construction work, underground workers are tied with safety ropes from waist to shoulder to enter the pipe well. However, in case of accidents, they can only climb by themselves without external force, which makes it impossible to be lifted up from underground in time, affecting the safety of underground work.

[0005] The wellhead is lower than the ground and cannot be protected. If there is water, sand, mud, etc. around the wellhead, the pipeline may be buried, and objects falling from the wellhead may easily injure the personnel underground, affecting the safety of underground operations;

[0006] Therefore, the present application provides a municipal utility pipe well construction auxiliary device to meet the needs. Utility Model Content

[0007] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology, and to propose a municipal public municipal pipe well construction auxiliary device.

[0008] The technical problem to be solved by the utility model is to provide a municipal public municipal pipe well construction auxiliary device to solve the problems of the existing municipal public municipal pipe well construction auxiliary device.

[0009] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0010] A municipal public municipal pipe well construction auxiliary device comprises: a base, a protective cylinder, a fixed block, a support rod, a connecting rod, a fixed seat, a cross bar, a rotating shaft, a frame, a traction shaft, a drum wheel and a crank, wherein a protective cylinder is installed at the upper end of the base, a fixed block is installed at the side of the base, a support rod is vertically installed at the top of the fixed block, a fixed seat is installed at the side of the support rod through a connecting rod, a cross bar is installed on the inner side of the fixed seat, a frame is installed on the cross bar through a rotating shaft, a traction shaft is installed at the inner upper end of the frame, a drum wheel is installed at the inner upper end of the frame, and a crank is installed on the outer side of the frame.

[0011] Preferably, the base is in a truncated cone shape, and a cavity is provided inside the base.

[0012] Preferably, the protective tube is in a circular ring shape, and is located at the upper opening of the base.

[0013] Preferably, two groups of fixing blocks are provided, and the two groups of fixing blocks are respectively located at the left and right ends of the base in a mirror-symmetrical manner.

[0014] Preferably, the fixing seat is erected in parallel directly above the protective tube via a supporting rod and a connecting rod, and the fixing seat is in a circular ring shape.

[0015] Preferably, the cross bar spans across the left and right sides of the fixing seat, the rotating shaft vertically penetrates the cross bar and extends downward to the bottom of the fixing seat, and the frame is movably connected to the cross bar through the rotating shaft.

[0016] Preferably, the crank is connected to the shaft roller of the traction shaft, and the crank extends outward to the outer end of the support rod.

[0017] Compared with the prior art, the utility model has at least the following beneficial effects:

[0018] 1. It can be erected above the well opening. By binding the safety rope to the traction shaft of the frame and then winding the safety rope around the drum disc, the frame can be rotated on the crossbar of the fixed seat through the rotating shaft, so that the direction of the frame at the lower end of the rotating shaft can be adjusted, which is convenient for working in different well directions. As the construction personnel move, the safety rope on the drum disc is gradually released. The guard outside the well can rotate the traction shaft and the drum disc by shaking the crank, so as to rewind the safety rope and pull the construction personnel to move outward, thereby assisting the underground personnel to quickly lift up from the well, effectively improving the safety of underground operations;

[0019] 2. The truncated cone-shaped base can be erected at the opening of the manhole cover of the pipe well to surround the opening of the manhole cover to form a protective structure, which can prevent the opening from being buried by debris around the wellhead and prevent objects from falling from the wellhead, thereby improving the safety of pipe well construction.
