Problems solved by technology
[0002] With the rapid development of economy and society, the lines in urban areas are gradually shifting from overhead lines to cables. Due to the increase of cable lines and pipelines, it brings great challenges to the work of cable inspection. Due to the increase of cable pipelines, manual opening of cable manhole covers It is time-consuming and labor-intensive, and the safety is not good, which poses a certain safety hazard to the well-opening personnel and the underground cables

Embodiment 2
[0016] Such as figure 2 Shown here is the preferred embodiment 2 of a trolley-type cable manhole cover opener of the present invention. Its structure is basically similar to that of embodiment 1, except that:
[0017] The upper surface of the lower crossbar 4 is provided with a placing plate 8 for placing a cable manhole cover. After the hand hoist 7 lifts the cable manhole cover to a certain height, pass the placement plate 8 through the lower crossbar 4 and erect it on the upper surface of the lower crossbar 4, then place the manhole cover on the placement plate 8, and then push the frame to prevent The manhole cover was hung under the hand hoist 7 to move, causing shaking and hitting the staff. Compared with pushing the trolley in the suspended state of the manhole cover, it is safer to place the manhole cover on the placement plate 8 to push the trolley.
[0018] An armrest 9 for staff pushing by hand is installed on the frame. Specifically, the armrest 9 can be installed o...

The invention relates to a trolley type cable well lid opener. The trolley type cable well lid opener comprises a frame, universal wheels and chain blocks, wherein the universal wheels are arranged at the bottom of the frame, and the chain blocks for hoisting a cable well lid are mounted on the frame. The frame comprises a top cross rod, four diagonal rods, two parallel upper cross rods, four vertical rods and two parallel lower cross rods, wherein the top cross rod is parallel to the upper cross rods, the upper cross rods are perpendicular to the lower cross rods, and the top cross rod is fixedly connected with the two upper cross rods through the four diagonal rods. The chain blocks are mounted on the top cross rod, two ends of the two upper cross rods and the upper ends of the four vertical rods are welded, two ends of the two lower cross rods and the lower ends of the four vertical rods are welded, and the universal wheels are arranged at the bottoms of the lower cross rods. The trolley type cable well lid opener has the advantages that the chain blocks are used for opening and hoisting the cable well lid, the hoisted cable well lid is moved by a trolley, and accordingly, cable inspection efficiency is improved greatly, and labor intensity of working personnel is relieved greatly; meanwhile, the working personnel is protected from being injured during manual carrying of the cable well lid.
Description
Technical field [0001] The invention belongs to the technical field of power cables, and specifically relates to a trolley-type cable manhole cover opener. Background technique [0002] With the rapid economic and social development, the lines in urban areas have gradually changed from overhead lines to cables. The increase in cable lines and pipelines has brought greater challenges to the work of cable inspections. Due to the increase in cable pipelines, the cable manhole covers have been opened manually The board is time-consuming and labor-intensive, and the safety is not good, which poses certain safety risks to the personnel and underground cables. Summary of the invention [0003] The invention provides a trolley-type cable manhole cover opener, which changes the current situation of manually opening cable manhole covers in the prior art, is more reasonable and effective for cable patrol planning, and greatly improves the efficiency of cable patrol. [0004] In order to solve...
