Abstract

The invention relates to a track type self-advancing device, comprising a thrusting mechanism, sliding rails, pad beam lift-up devices, roller outriggers and a pad beam device. The track type self-advancing device is characterized in that a front fulcrum and a back fulcrum are arranged on the longitudinal position of the gravity center of hoisting equipment, the pad beam device is placed on the front fulcrum, two sliding rails are symmetrically distributed on two sides of the lower part of a pad beam of the pad beam device, the sliding rails are connected with the pad beam through pins, the pad beam lift-up devices are vertically arranged on the outer sides of the sliding rails, and the back fulcrum uses multiple rows of directional nylon roller outriggers as a driven fulcrum. The power device of the invention is installed on the front fulcrum, the alternative advance of the equipment and the rails is achieved through the expansion of a jack, the back fulcrum uses multiple rows of the nylon roller outriggers as the driven fulcrum, and the linear move of the equipment can be ensured in the process of forward move. The device has the advantages of simple operation and high move speed.

Description

technical field [0001] The invention relates to a walking displacement device for equipment, in particular to a self-propelled displacement device suitable for large hoisting equipment. Background technique [0002] In large-scale structural hoisting projects, in addition to general-purpose hoisting equipment such as crawler cranes, truck cranes, and floating cranes, most non-universal equipment is used. In the design of non-universal lifting equipment, the walking displacement device is a very important part. The walking method can usually be dragged by a winch, a walking hydraulic jacking device, or other wheeled power devices. Reasonable and applicable design can greatly facilitate the mobile positioning of large-scale equipment. The walking and moving device can not only realize the function of moving the equipment, but also realize the function of self-propelling. But at present, the shifting method and moving speed of the walking shifting device of large-scale non-un...
