Abstract

A wheeled engineering vehicle includes a frame; a first telescopic cylinder disposed on the frame; and a stabilizer assembly connected with the first telescopic cylinder and configured to rotate relative to the frame under drive of the first telescopic cylinder. The stabilizer assembly includes: a first stabilizer leg having a hollow structure; a second telescopic cylinder disposed in the first stabilizer leg; a second stabilizer leg configured to extend or retract relative to the first stabilizer leg under drive of the second telescopic cylinder, and the first stabilizer leg configured to radially limit the second stabilizer leg; and a stabilizer foot connected to the second end of the second stabilizer leg and configured to be in contact with the ground to support the vehicle. The first stabilizer leg, the second stabilizer leg and the stabilizer foot cooperate to support the whole vehicle to improve the stability of the vehicle.

First claim

The invention claimed is:

1. A wheeled engineering vehicle for improving operation efficiency, comprising:
a frame;
a first telescopic cylinder disposed on the frame; and
a stabilizer assembly connected with the first telescopic cylinder and configured to rotate relative to the frame under a drive of the first telescopic cylinder, the stabilizer assembly comprising:
a first stabilizer leg constructed to be of a hollow structure, of which a first end is articulated with the frame, and of which a second end is a free end;
a second telescopic cylinder disposed in the first stabilizer leg;
a second stabilizer leg, of which a first end in a telescoping direction is located in the first stabilizer leg and connected to the second telescopic cylinder, and of which a second end in the telescoping direction is located outside the first stabilizer leg via the second end of the first stabilizer leg, the second stabilizer leg being configured to extend or retract relative to the first stabilizer leg under a drive of the second telescopic cylinder, and the first stabilizer leg being configured to limit the second stabilizer leg, wherein the second stabilizer leg and the second telescopic cylinder are rotatably connected, and wherein the stabilizer assembly comprises a bearing, through which the second stabilizer leg is connected to the second telescopic cylinder; and
a stabilizer foot connected to the second end of the second stabilizer leg and configured to be in contact with the ground to support the wheeled engineering vehicle.

2. The wheeled engineering vehicle according to claim 1 , wherein the stabilizer assembly further comprises a first supporting member, wherein the first supporting member is disposed in the first stabilizer leg and is in clearance fit with a part of the second stabilizer leg located inside the first stabilizer leg.

3. The wheeled engineering vehicle according to claim 2 , wherein the first supporting member comprises a shaft sleeve.

4. The wheeled engineering vehicle according to claim 1 , wherein a first end of the first telescopic cylinder is articulated with the frame, and a second end of the first telescopic cylinder is articulated with the first stabilizer leg.

5. The wheeled engineering vehicle according to claim 4 , wherein the first telescopic cylinder is articulated with the second end of the first stabilizer leg.

6. The wheeled engineering vehicle according to claim 1 , wherein the stabilizer foot is rotatably connected to the second end of the second stabilizer leg.

7. The wheeled engineering vehicle according to claim 6 , wherein the stabilizer foot is provided with at least two second supporting members, and the stabilizer foot is rotatable so that one of the at least two second supporting members contacts the ground for supporting.

8. The wheeled engineering vehicle according to claim 7 , wherein at least one of the at least two second supporting members is different from the other second supporting members in structure.

9. The wheeled engineering vehicle according to claim 7 , wherein the second supporting member comprises a resilient member, a toothed member, or a hooked member.

10. The wheeled engineering vehicle according to claim 7 , wherein the stabilizer assembly further comprises a positioning structure, which is configured to lock the stabilizer foot and the second stabilizer leg when the stabilizer foot rotates to cause one of the second supporting members supports the ground.

11. The wheeled engineering vehicle according to claim 10 , wherein the positioning structure comprises a positioning member, at least two first positioning holes formed in the stabilizer foot, and a second positioning hole formed in the second stabilizer leg; one of the at least two first positioning holes being aligned with the second positioning hole when one of the second supporting members supports the ground, and the positioning member being configured to be inserted into the first positioning hole and the second positioning hole to lock the stabilizer foot and the second stabilizer leg.

12. The wheeled engineering vehicle according to claim 1 , comprising an excavating side, wherein the stabilizer assembly is disposed at the excavating side.
