Description

A kind of hoisting crane bottom support block
Technical field
The utility model relates to a kind of hoisting crane bottom support block.
Background technology
Hoisting crane is a kind of very conventional lifting appliance, when hoisting heavy, supported by hydraulic support leg, avoid hoisting crane run-off the straight in lifting process, hydraulic support leg of the prior art just has a very little bearing surface, and the area of contact therefore between hydraulic support leg and ground is limited, when running into comparatively soft soil, such supporting leg is easy to be absorbed in ground, causes hoisting crane to be turned on one's side.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of hoisting crane bottom support block, and this device can increase the area of contact between hydraulic support leg and ground, avoids, avoids hoisting crane to turn on one's side.
For solving the problem, the utility model adopts following technical scheme:
A kind of hoisting crane bottom support block, comprise bottom bearing block, the top of described bottom bearing block is provided with a sleeve, described sleeve and described bottom bearing block are integral type, the adapter sleeve connecting hoisting crane hydraulic pressure leg is arranged with in described sleeve, the first screw is fastened with between described sleeve and described adapter sleeve, on the outer circumference surface of described bottom bearing block, annular is provided with the bayonet socket of more than three, additional bearing block is combined with in described bayonet socket, described additional bearing block has a clamp be engaged in described bayonet socket, the second screw is fastened with between described clamp and described bayonet socket, described clamp is engaged in after in described bayonet socket, the lower surface of described additional bearing block extends to the outside of described bottom bearing block.
As preferred technical scheme, the second screw between single described clamp and described bayonet socket is provided with two or more.
As preferred technical scheme, the outer circumference surface of described adapter sleeve is provided with the fixed orifice of fixed crane hydraulic pressure leg, the wall thickness of described adapter sleeve is 8mm-12mm.
As preferred technical scheme, described bottom bearing block and additional bearing block are alloy steel and make, and described additional bearing block has the outside face of a circular arc, and described additional bearing block and described clamp are integral type structure.
As preferred technical scheme, the close bottom position place of described adapter sleeve is provided with the positioning groove coordinating described first screw, and described positioning groove and described adapter sleeve are coaxially arranged.
The beneficial effects of the utility model are: this device can increase the area of contact between hydraulic support leg and ground, avoid, hoisting crane is avoided to turn on one's side, additional bearing block simultaneously in this device can carry out selectivity dismounting according to the character of soil property, meet and use needs, the structure of this device is comparatively simple, and cost is comparatively cheap, is applicable to promoting the use of.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
