Summary of the invention
The purpose of this utility model provides a kind of crawler type hitch that is applicable to engineering truck for existing weak point in above-mentioned prior art just.Hitch of the present utility model can significantly improve the load-carrying capacity of single suspension, reduces the average unit pressure of ground of complete machine, improves the crossing ability of complete machine.
The purpose of this utility model can realize by following technique measures:
Crawler type hitch of the present utility model comprises creeper undercarriage, the crossbeam combined with creeper undercarriage wheel carrier middle part in hinged way, vertical tie-beam that one end combines with crossbeam, the other end combines with suspension main structure lower end in hinged way, and the hydraulic actuating cylinder that an end is connected with suspension main structure top, the other end is connected with crossbeam or vertical tie-beam; And described suspension main structure, hydraulic actuating cylinder and vertical tie-beam form triangular structure in the luffing plane of vertical tie-beam.
The utility model is separately installed with a set of creeper undercarriage at the two ends of described crossbeam in symmetrically arranged mode; Described crossbeam combines with vertically between tie-beam, adopting articulated manner.
The utility model also can be installed a set of creeper undercarriage in the mode of one-sided setting at an end of described crossbeam; Described crossbeam combines with vertically between tie-beam, adopting affixed mode.
The beneficial effects of the utility model are as follows:
The crawler type provided by the utility model hangs, and can significantly improve the load-carrying capacity of single suspension, reduces complete machine axis quantity, reduces the length dimension of complete machine and the average unit pressure of ground of complete machine, improves maneuverability and the crossing ability of complete machine.

The specific embodiment
The utility model is elaborated below in conjunction with embodiment (accompanying drawing).
Embodiment 1
As shown in Figure 1, 2, 3, the crawler type hitch that is applicable to engineering truck of the present utility model comprises creeper undercarriage 5, the crossbeam 4 combined with creeper undercarriage wheel carrier middle part in hinged way, one end combines with crossbeam 4 in hinged way, the other end in hinged way with the vertical tie-beam 3 that hangs main structure 1 lower end and combine, and an end with hang that main structure 1 top is connected, the other end with crossbeam 4(referring to Fig. 4) or vertical tie-beam 3(referring to Fig. 1,8) hydraulic actuating cylinder 2 be used to regulating suspension height that is connected; And described suspension main structure 1, hydraulic actuating cylinder 2 and vertical tie-beam 3 form triangular structure (referring to Fig. 4) in the luffing plane of vertical tie-beam 3; Wherein said creeper undercarriage 5 is two covers, in symmetrically arranged mode, is hinged on respectively the two ends of crossbeam (4).
More specifically, the upper surface of described suspension main structure 1 connects with chassis, is generally to support with engineering vehicle chassis and connect by revolution, realizes the rotation of hanging to facilitate, and completes turning to of complete machine.In suspended structure, hang main structure 1, hydraulic actuating cylinder 2 and vertical tie-beam 3 and can form a stable triangle, the pressure that hangs main structure 1 upper surface can reach crossbeam 4 and finally reach creeper undercarriage 5 by this stable triangle.Because the ground contact area of creeper undercarriage 5 is more much bigger than the ground contact area of tire, therefore can greatly reduce the grounding pressure of complete machine, improve the crossing ability of complete machine.
The hinged purpose of crossbeam described in the utility model 4 and vertical tie-beam 3 can realize that crossbeam 4 is around this hinge rotation (as shown in Figure 7), have on the road surface of horizontal wall inscription, this suspension can, in the situation that the upper surface level of main structure 1 is hung in maintenance, be distributed in by designing requirement the bearing capacity that hangs main structure 1 on two creeper undercarriages 5.
The structure of the present embodiment as shown in Figure 5,6, is with the difference of embodiment 1: at an end of described crossbeam 4, in the mode of one-sided setting, a set of crawler travel machine 5 is installed, and described crossbeam 4 and vertical tie-beam 3 rigid attachment; Can regard a member as, therefore in order to make the stressed less of described hydraulic actuating cylinder 2, the other end of hydraulic actuating cylinder 2 is articulated in to crossbeam 4.
As shown in Fig. 9,10, the engineering truck of the utility model mechanism to be installed and with the construction machinery and equipment that uses rubber-tyred to hang, to be compared, this project machinery has larger load-carrying capacity, less grounding pressure and better crossing ability, and traveling gear is not prone to skidding.This project machinery can also be in certain gradient scope, and the height hung by regulating each, make chassis remain on horizontality, and in the time of can guaranteeing like this on complete machine Zai Po road to walk, each hangs still has equal load.
