Abstract
The utility model relates to a manhole cover opening trolley with a built-in magnet, and belongs to the technical field of mechanical operations. The manhole cover opening trolley comprises a lever trolley and a cover opening device. The lever trolley comprises two metal actuating arms which are fixedly connected and a trundle used for fixing the metal actuating arms. The cover opening device is composed of a magnetic switch and the permanent magnet fixed into the magnetic switch through a screw, the inner portion of the magnetic switch is hollow, the lower end of the magnetic switch is open, and the upper end of the screw is connected with the metal actuating arms. The manhole cover opening trolley with the built-in magnet is simple in structure and convenient to use and can be widely applied to opening and moving of various cast-iron manhole covers.
Description
Technical field
The utility model relates to a kind of manhole cover opening car of built-in magnet, belongs to mechanical work technical field.
Background technology
Although it is very heavy that the manhole cover on road surface, outside is unlikely to weigh, wanting easily it to be opened and is moved not is that part is easy to thing.In the operation of opening and moving at traditional manhole cover, that can only with crowbar, to well lid, be entered to pry open and require great effort by several operating personals moves, and this method is not only wasted a large amount of manpowers and time, and well lid is had to certain destructiveness.
Summary of the invention
The utility model provides a kind of manhole cover opening car of built-in magnet, simple in structure, easy to use, can be widely used in the unlatching of various cast iron manhole cover and move.
The structure of the manhole cover opening car of built-in magnet of the present utility model is: comprise lever vehicle 4 and cover opening device, lever vehicle 4 comprises the trundle 8 of two metal arm of forces 7 that are fixedly connected with and the fixing metal arm of force 7; Cover opening device forms by the uncovered magnet-switch 1 of inner hollow, lower end with by the permanent magnet 3 that screw rod is fixed on magnet-switch 1 inside, and the upper end of screw rod is connected with the metal arm of force 7.
One end of two metal arm of forces 7 of described lever vehicle 4 is hinged by S. A. 9, and by folding little steel bar 6, both maximum angles is adjusted into 90～180 °.
Two metal arm of forces 7 of described lever vehicle 4 are fixedly mounted on two trundles 8 by base 5.
The other end of a metal arm of force 7 of described lever vehicle 4 is cylinder, and the screw tip of cover opening device is the annulus mating with cylinder.
The other end of another root metal arm of force 7 of described lever vehicle 4 is T-shaped shape cart handle 10.
During use, only need be the magnet-switch handle backspin of magnet-switch, make permanent magnet tightly hold well lid, then the metal arm of force of lever vehicle is inserted in the iron hoop of handle, utilize the lever principle of lever vehicle just manhole cover can be mentioned and move.Design can be accomplished laborsaving, object easily like this.
The utility model has the advantage of that this opening bassinet structure is simple, it is firm to attract, desorption is convenient, applied range.
