Description

Tail landing leg structure for crane

Technical Field

The utility model relates to a hoist engineering machine tool field, concretely relates to tail landing leg structure that hoist was used.

Background

The lorry-mounted crane transport vehicle is widely applied to industries such as construction, industry, transportation and the like which are closely related to people as an important engineering vehicle. The truck with the crane is a special vehicle integrating lifting and transportation, the lifting capacity and the safety performance are the most important indexes of the vehicle and the most basic requirements approved by users.

However, with the improvement of the lifting capacity of the vehicle, the stability, the structural member supporting capacity and the service life of the whole vehicle are greatly tested; therefore, the stability and the supporting capability of the lorry-mounted crane become important factors for restricting the hoisting capability.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a tail landing leg structure that hoist that stability is good was used.

The technical scheme of the utility model is that: the utility model provides a tail landing leg structure that hoist was used, includes two tail landing leg systems of setting at the crane boom tail end of symmetry, and tail landing leg system includes telescopic cylinder, tail landing leg, and the fixed welding of one end of telescopic cylinder is in the crane boom, and telescopic cylinder's the other end is fixed on the tail landing leg, and telescopic cylinder drives the flexible of tail landing leg, and two tail landing legs are "eight" font and distribute.

In a further technical scheme, the angle between the two tail support legs is 10-30 degrees.

The utility model has the advantages that:

the utility model discloses a tail landing leg stretches out under the effect of flexible hydro-cylinder for the increase of the dish interval of two tail landing legs, thereby make the bearing of crane truck frame more stable, for prior art, the utility model discloses simple structure, safe and reliable.

Drawings

Fig. 1 is a schematic structural plan view of the present invention;

FIG. 2 is a schematic cross-sectional view at AA' of FIG. 1.

The crane comprises a crane support 1, a telescopic oil cylinder 2, a tail supporting leg 3.

Detailed Description

The invention will be further elucidated below by means of non-limiting examples, with the understanding that the invention is not limited thereto.

As shown in fig. 1-2, the utility model relates to a tail landing leg structure that hoist was used, including two tail landing leg systems of setting at 1 tail end of crane support of symmetry, tail landing leg system includes telescopic cylinder 2, tail landing leg 3, and the fixed welding of one end of telescopic cylinder 2 is in crane support 1, and telescopic cylinder 2's the other end is fixed on tail landing leg 3, and telescopic cylinder 2 drives the flexible of tail landing leg 3, and two tail landing legs 3 are "eight" font and distribute, and the adjustable angle between two tail landing legs 3 is 10-30.

Tail landing leg 3 stretches out under telescopic cylinder 2's effect, through adjusting telescopic cylinder 2, can be so that two tail landing legs 3's dish interval increase to make crane frame's the bearing more stable, for prior art, the utility model discloses simple structure, safe and reliable.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

Claims (2)

1. The utility model provides a tail landing leg structure that hoist was used which characterized in that: the crane support comprises two tail supporting leg systems which are symmetrically arranged at the tail end of the crane support, wherein each tail supporting leg system comprises a telescopic oil cylinder and a tail supporting leg, one end of each telescopic oil cylinder is fixedly welded in the crane support, the other end of each telescopic oil cylinder is fixed on the tail supporting leg, the telescopic oil cylinders drive the tail supporting legs to stretch out and draw back, and the two tail supporting legs are distributed in a splayed shape.

2. A tail leg structure for a crane according to claim 1, wherein: the angle between the two tail legs is 10-30 degrees.
