WHEELED ENGINEERING VEHICLE CAPABLE OF IMPROVING OPERATION EFFICIENCY

摘要

Disclosed is a wheeled engineering vehicle capable of improving the operation efficiency. The wheeled engineering vehicle comprises: a frame; first telescopic cylinders arranged on the frame; and support leg assemblies which are connected to the first telescopic cylinders and are configured to rotate relative to the frame under the drive of the first telescopic cylinders. Each support leg assembly comprises: a first support leg configured to be of a hollow structure, wherein a first end of the first support leg is hinged to the frame, and a second end thereof is a free end; a second telescopic cylinder arranged in the first support leg; a second support leg, wherein a first end of the second support leg is located in the first support leg and is connected to the second telescopic cylinder, a second end of the second support leg is located outside the first support leg by means of the second end of the first support leg, the second support leg is configured to stretch out and draw back relative to the first support leg under the drive of the second telescopic cylinder, and the first support leg is configured to limit the second support leg in a radial direction; and a support disk which is connected to the second end of the second support leg and is configured to be in contact with the ground so as to support the wheeled engineering vehicle. The first support leg, the second support leg and the support disk cooperate to support the whole vehicle, thereby being capable of improving the stability of the whole vehicle.
