The invention discloses a lateral three-support-point multiple-caterpillar-band guiding support device which comprises two steering lateral caterpillar bands, a fixed lateral caterpillar band and a portal frame. The fixed lateral caterpillar band is fixed on the lower end face of the front portion of the portal frame, and the two steering lateral caterpillar bands are symmetrically distributed on two sides of a central line of the portal frame. An oil cylinder is fixed on the lower end face of the middle portion of the portal frame, and the other end of the oil cylinder is connected with a steering arm I through a hinge shaft I. The steering arm I is connected with a steering arm II through a hinge shaft II. Ball bases are fixed on the upper end faces and the lower end faces of the steering arm I and the steering arm II, and balls are fixed on the ball bases through retaining frames in a clamping-connection mode. The hinge connecting position of the steering arm I and the steering arm II is clamped between an upper plate and a lower plate of the portal frame. A guide structure is changed to enable mechanism internal friction in the lateral three-support-point multiple-caterpillar-band steering process to be rolling friction, the efficiency of a steering mechanism is greatly improved, face guide is changed into linear guide, freedom degree of a guide pair is increased, and susceptibility of ground unevenness is reduced.
Description
technical field [0001] The invention relates to multi-crawler equipment in an open-pit mine, in particular to a running guide support device for a large-scale multi-crawler earthmover. Background technique [0002] At present, the problem of severe wear can only be solved by embedding special wear-resistant materials on the steering arm structure plane for the three-point multi-track guide support device on the side. It has the following disadvantages: [0003] 1. The production process is difficult; [0004] 2. With the deterioration of the on-site use environment, the friction force during the steering process will increase sharply, which will greatly reduce the steering efficiency of the mechanism and have an impact on the structure; [0005] 3. Once the wear-resistant material fails, it is difficult to repair; [0006] 4. Poor ground adaptability. Contents of the invention [0007] The technical problem to be solved by the present invention is to provide a side thr...
