Embodiment Construction

[0019] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0020] Such as Figure 1 to Figure 3 As shown, a crawler walking device includes crawler frames and track shoes 3 on the left and right sides. The crawler frame includes an outer box body 2 and an inner box body 1. The inner box body 1 is located in the middle of the outer box body 2 to form a crawler frame together. Track shoes 3 are also wound around the outer circumference of the body 2 and the inner box body 1 .

[0021] Outer box body 2 two ends are provided with guide wheel 21 and drive wheel 23, and the bottom of outer box body 2 two ends is equipped with track roller 20, and middle part does not have track wheel 20, and box body 2 central planes are arranged symmetrically outside track w...

Abstract

The invention discloses a crawler belt traveling device comprising a left crawler belt frame, a right crawler belt frame and crawler belt plates. The crawler belt plates are arranged on the peripheries of the crawler belt frames. Each crawler belt frame comprises an outer box and an inner box, a guide wheel and a driving wheel are arranged at two ends of the outer box, bearing wheels are arranged at the bottoms of the inner box and the outer box and located on the crawler belt plates, the bearing wheels at the inner box are arranged between the bearing wheels at the bottom of the outer box, and a hydraulic oil cylinder is arranged between the outer box and the inner box and used for driving the outer box to move upwardly relative to the inner box. The invention further provides a steering method of a crawler belt crane. The steering method of the crawler belt crane has steering assisting performance and improves steering performance of the crawler belt crane.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a crawler traveling device and a steering method for a crawler crane. Background technique [0002] The overall weight of crawler cranes is generally relatively large. In order to increase the grounding area and reduce the grounding specific pressure, the length and width of the crawler frame and track shoes are generally increased as much as possible within the allowable range, and the crawler frame is a whole, but The resulting result is that when the crawler frame performs unilateral steering, the resistance torque often exceeds the torque provided by the travel reducer, and the crawler crane cannot turn. [0003] In view of the above situation, the commonly used solution is to replace the motor and travel reducer to increase its output torque, but this will cause a sharp increase in cost, and the ability of the hydraulic system cannot be fully utilized during normal trave...
