Abstract

The utility model provides a vehicle frame rear segment and an auto-crane. The vehicle frame rear segment comprises a front landing leg box, a back landing leg box, a first girder and a second girder, wherein the first girder and the second girder are arranged on the front landing leg box and the back landing leg box. Compared with an existing monospar, the first girder and the second girder have small sizes, and therefore the weight of the vehicle frame rear segment can be reduced, materials are saved, and the production cost is lowered. In addition, on the basis of achieving the purposes, the vehicle frame rear segment is provided with two girders, namely, the first girder and the second girder, and therefore the torsion resistant performance of the vehicle frame rear segment is improved.

Further, described the first beam is positioned at the left side of described front leg strut case and described rear support leg case, and described the second beam is positioned at the right side of described front leg strut case and described rear support leg case.
Further, the two ends of described the first beam are separately fixed on described front leg strut case and the described rear support leg case, and the two ends of described the second beam are separately fixed on described front leg strut case and the described rear support leg case.
Further, described the first beam, described the second beam are welded in described front leg strut case and described rear support leg case.
Further, the junction of described the first beam, this second beam and described front leg strut case and described rear support leg case is provided with reinforced rib.
Further, described vehicle frame back segment also comprises crossbeam, and the two ends of described crossbeam are connected on described the first beam and described the second beam.
Further, described vehicle frame back segment also comprises connector, and the two ends of described connector are connected on described the first beam and described the second beam.
Further, described connector is the revolution support ring.
Further, described connector is welded on described the first beam and described the second beam.
The first beam of the present utility model and the second beam have less volume with respect to existing single-spar construction, therefore, can reduce the weight of this vehicle frame back segment, save materials, reduce cost of manufacture.In addition, on the basis that achieves the above object, this vehicle frame back segment is provided with two beams, i.e. this first beam and this second beam can improve the torsional property of this vehicle frame back segment.
A kind of car hosit that is provided with above-mentioned vehicle frame back segment that the utility model provides, because above-mentioned vehicle frame back segment has above-mentioned technique effect, therefore, the car hosit that is provided with this vehicle frame back segment also has corresponding technique effect.
Description of drawings
The accompanying drawing that consists of a part of the present utility model is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Figure 1 shows that the structural representation of existing vehicle frame back segment.
Figure 2 shows that the structural representation of the vehicle frame back segment of the utility model embodiment.
Figure 3 shows that the structural representation of the vehicle frame back segment of another embodiment of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 2, the utility model embodiment provides a kind of vehicle frame back segment, and this vehicle frame back segment is applied in the hoisting crane.This vehicle frame back segment comprises front leg strut case 3, rear support leg case 4, the first beam 5, the second beam 6 and connector 7.
This front leg strut case, rear support leg case are used for supporting this first beam 5 and this second beam 6.
This first beam 5 is arranged on this front leg strut case 3 and this rear support leg case 4 with this second beam 6.Particularly, the two ends of this first beam 5 are separately fixed on this front leg strut case 3 and this rear support leg case 4.The two ends of this second beam 6 are separately fixed on this front leg strut case 3 and this rear support leg case 4, and this first beam 5 is positioned at the left side of this front leg strut case 3 and this rear support leg case 4, and this second beam 6 is positioned at the right side of this front leg strut case 3 and this rear support leg case 4.
Preferably, this first beam 5 is arranged on this front leg strut case 3 and this rear support leg case 4 abreast with this second beam 6.Above-mentioned this first beam 5, this second beam 6 are preferably welding with the connection mode of this front leg strut case 3 and this rear support leg case 4.For the rigidity and stability that improves this vehicle frame back segment, this first beam 5, this second beam 6 are provided with reinforced rib 9 with the junction of this front leg strut case 3 and this rear support leg case 4.
The two ends of this connector 7 are connected on this first beam 5 and this second beam 6.This connector 7 is preferably the revolution support ring, and the swing type mechanism of this car hosit is arranged on this connector 7 rotationally.This connector 7 is preferably welding with the connection mode of this first beam 5 and this second beam 6.
