Description

Movable type is stepped on vehicle bridge

The utility model relates to a kind of movable type and steps on vehicle bridge, and it belongs to a kind of device of wheeled mobile loading and unloading logistics.

The existing various vehicle bridge of stepping on all is fixed, can only be installed on various fixing loading and unloading places and use, in the melt pit of locating as goods platform etc.Therefore this fixed type is stepped on vehicle bridge and is existed shortcomings such as floor area is big, range of use is little and can not move.

The purpose of this utility model provides that a kind of floor area is little, range of use is wide, simple to operate and mobile movable type is stepped on vehicle bridge.

Task of the present utility model is achieved in that this steps on vehicle bridge and comprise a pontic, is located at the railing of both sides above the pontic, is located at the attachment strap of pontic front end and rear end, and wherein it also comprises chaining, draw bar, force pump device, wheel, wheel carrier and oil cylinder; Chaining is located at the front end both sides of pontic, draw bar be located at the pontic front middle part below, the force pump device is located at the side below the pontic middle part, wheel is erected at the bottom surface at pontic middle part, its front end is provided with two wheels, the bottom surface at its rear end and pontic middle part is hinged, and the afterbody of oil cylinder and the front middle part of wheel carrier are hinged, and the head of its piston rod and pontic middle part are hinged.

Because the utility model adopted technique scheme, but therefore compare with background technology have that floor area is little, range of use is wide, advantage such as simple to operate and mobile operation.Significantly enlarged the field of application of stepping on vehicle bridge.

The utility model will be further described below in conjunction with drawings and Examples.

Accompanying drawing is a structural representation of the present utility model.

As shown in drawings, it comprises a pontic 3 that made by square steel, that be shaped to truss-like the utility model, be located at the railing 7 of both sides above the pontic 3, be located at the attachment strap 8 of pontic 3 front ends and rear end, wherein it also comprises chaining 1, draw bar 2, force pump device 4, wheel 9, wheel carrier 5 and oil cylinder 6; Chaining 1 is located at the front end both sides of pontic 3, the draw bar 2 that need use when mobile complete machine is located at below pontic 3 front middle parts, force pump device 4 is located at the side below pontic 3 middle parts, wheel carrier 5 is located at the bottom surface at pontic 3 middle parts, its front end is provided with two wheels 9, the bottom surface at its rear end and pontic 3 middle parts is hinged, and the front middle part of the afterbody of oil cylinder 6 and wheel carrier 5 is hinged, and the head of its piston rod and pontic 3 middle parts are hinged.

Principle of work of the present utility model is: shake force pump, cylinder action, jack-up pontic, make anterior attachment strap be higher than the base plate of wagon box, unclamp fuel-return valve after lorry berths and puts in place and make the anterior attachment strap of pontic be overlapped on wagon box afterbody base plate reliably, chaining is hung on the lorry, prevent to slip suddenly car.Can carry out loading and unloading operation this moment.Behind the completed loading, unclamp chaining, the lorry that drives away returns to initial condition with pontic again.
