Manhole cover electromagnetism uncovering trolley

Abstract

The invention discloses a manhole cover electromagnetism uncovering trolley. The manhole cover electromagnetism uncovering trolley comprises a trolley frame, four trolley wheels, an upper fixing block, a lower fixing block, a movable pulley, a fixed pulley, a traction main rope, a traction auxiliary rope, a rope coiling wheel, a fixing blot, an electromagnetic chuck and a power source, wherein thefour trolley wheels are fixed at bottoms of four supporting legs of the trolley frame, a cross beam horizontally arranged is fixed on the trolley frame, a supporting block is fixed in the middle of the cross beam, the rope coiling wheel is connected onto the supporting block through a middle shaft, the traction main rope is wound around the rope coiling wheel, and the lower end of the traction main rope is connected with a pulley block mechanism, and connected with the electromagnetic chuck through the pulley block mechanism. The manhole cover electromagnetism uncovering trolley drives a pulley block to perform transmission by shaking the rope coiling wheel through a crank handle, realizes the effect of sucking up and placing a manhole cover by utilizing rising and falling of the tractionmain rope, saves time and labor, cannot damage the manhole cover, and improves safety and stability of the manhole cover when the manhole cover is carried.

Description

technical field [0001] The present invention relates to the field of municipal facilities manufacturing, and more specifically, relates to a manhole cover electromagnetic opening vehicle. Background technique [0002] Along with the development of city, need more and more underground pipelines such as telecommunications, electric power, water supply and drainage, thereby the inspection well cover on the road is also more and more. In order to be firm and anti-theft, the manhole cover is usually heavy and tightly installed. The manufacture of present manhole cover generally adopts cast iron and concrete, and the sewer manhole cover weight is generally 50-70kg, and the cable manhole cover weight is generally 90-120kg. During use, the gap between the well and the manhole cover will be filled with impurities, making it very difficult to open the manhole cover. [0003] In order to facilitate the opening of the manhole cover, most of the manhole covers are at least provided wit...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the existing iron manhole cover basically depends on construction personnel using picks to open it manually, which is not only time-consuming and laborious but also easy to damage the manhole cover. A kind of manhole cover electromagnetic opening vehicle is proposed, which can Save time and effort to open and carry the manhole cover without causing damage to the manhole cover
