Abstract
The utility model relates to the field of iron manhole cover opening, in particular to a magnetic hoist for a high-voltage cable manhole cover, which is characterized by comprising a magnetic hoist body, a portal frame and a hoisting lead screw, wherein one end of the hoisting lead screw is suspended on the portal frame through a nut, the other end of the hoisting lead screw is connected with the magnetic hoist body, roller carriers are arranged at two legs of the portal frame respectively, and at least two rollers are arranged on each roller carrier. A gasket is arranged between the nut and the portal frame, and a ratchet wrench is arranged on the nut in a matched manner. Compared with the prior art, the magnetic hoist has the advantages that the iron manhole cover can be opened conveniently and effortlessly, labor intensity of operators is relieved, personal safety during operation is guaranteed, the magnetic hoist is portable, practical and capable of preventing sparks due to knocking of the manhole cover and further preventing inflammable gas explosion in a manhole, and can also serve as a transport tool to realize short-distance movement of the manhole.
Description
Technical field
The utility model relates to the irony well lid and opens field, particularly a kind of high-tension cable well lid magnetic-type hoisting device.
Background technology
At present, at municipal construction with in safeguarding, often need handle the underground installation of departments such as plumbing, electric power and coal gas; The unlatching of general well lid all is with the crowbar sled, and the well lid edge is often bad by sled, and the well lid edge does not stitch sometimes; Also to knock, because there are fire gasess such as methane in the down-hole, when knocking well lid generation spark; The interior fire gases of well is blasted, cause sudden hurt accident.
Summary of the invention
The utility model provides a kind of high-tension cable well lid magnetic-type hoisting device, overcomes the deficiency of prior art, can open the irony well lid convenient and strength-savingly, alleviates labor intensity of operating personnel, guarantees the personal safety of working process.
The utility model is realized through following technical scheme:
High-tension cable well lid magnetic-type hoisting device; Comprise magnetic field pulse hoist, door-shaped frame and lifting leading screw; Lifting leading screw one end is hung on door-shaped frame through nut; The lifting leading screw other end is connected with magnetic field pulse hoist, and two foots of said door-shaped frame are respectively equipped with wheel carrier, minimumly on each wheel carrier is provided with two rollers.
Be provided with pad between said nut and the door-shaped frame.
Said nut is provided with supporting free wrench.
Compared with prior art, the beneficial effect of the utility model is: can open the irony well lid convenient and strength-savingly, alleviate labor intensity of operating personnel; Guarantee the personal safety of working process, light, practical, prevent because of knocking well lid; Produce spark; Cause fire gases blast in the well, can also use, realize that the short range of well lid is moved as transportation means.
