Crab-like type obstacle avoidance crane

Abstract

The invention discloses a crab-like type obstacle avoidance crane which comprises a lifting frame, a crab-like skeleton, a walking drive mechanism and a lifting device installed on the lifting frame;the crab-like skeleton comprises a front bracket, a back bracket and a T-shaped base; the front bracket and the back bracket are both formed by fixedly connecting two crab-like frame supporting legs through a beam and are installed on the two sides of the lifting frame through rotation pairs respectively; the top of each crab-like frame supporting leg is provided with a chute; the two wing ends ofthe T-shaped base are installed in the chutes of the two crab-like frame supporting legs on the same side through sliding shafts respectively; the middle part end of the T-shaped base is connected with the lifting frame on the corresponding side through a linear guide rail sliding block structure; opening and closing of the front bracket and the back bracket are regulated with a distance regulating device to realize lifting of the lifting frame; and the walking drive mechanism is used for driving the crab-like skeleton to walk. The displacement type crane provided by the invention is simple in lifting structure and good in flexibility, cannot cause damages on goods due to hard collision and can lift multiple goods at one time.

Description

technical field [0001] The invention belongs to the field of cranes, and relates to a displacement crane, in particular to a crab-like obstacle avoidance crane. Background technique [0002] As my country's economic development changes from extensive growth to intensive growth, the development model of port machinery is also changing. Port loading and unloading equipment is changing from the past large-scale, high-speed, and automated to specialized, intelligent, energy-saving and environmentally friendly, and drives new technological progress. Due to the limited area of ​​the port site, it is particularly important to make efficient use of the port area. At present, traditional bridge cranes can only arrange one set of hoisting mechanisms in a single working area, with low space utilization and a single path. Therefore, people pay more and more attention to the research of new cranes. Arranging multiple hoisting mechanisms in a single working area can also be used as a s...
