Embodiment Construction

[0013] Examples see figure 1 As shown, the sliding device of this double tower mast giant self-elevating lifting equipment is composed of a PTFE plate 1, an elastic backing plate 2 and a steel bottom plate 3 bonded from top to bottom. The PTFE plate The upper surface is uniformly covered with granular micro-protrusions 5, the gaps between the micro-protrusions are oil injection holes 4, and a circle of guards 6 is formed around the tetrafluoro plate, and the height of the guards is the same as that of the micro-protrusions 5 . The above-mentioned elastic backing plate 2 can be rubber or plastic.

[0014] The invention can be processed into a square shape, and the use is not limited by the direction, as long as the direction of the force is changed, it will walk in the opposite direction of the force, which is very convenient to use.

Abstract

The invention relates to a sliding device of a dual-tower-mast giant self-lifting crane, the device is formed by the combination of a polytetrafluoroethylene plate, an elastic padding plate and a steel bottom plate in a layered adhesion manner from top to bottom, granular micro-bumps are evenly and fully distributed on the upper surface of the polytetrafluoroethylene plate, a gap among the micro-bumps is an oil filling hole cavity, the periphery of the polytetrafluoroethylene plate is enclosed to form a circle of protective sides, and the height of the protective sides is the same with the height of the micro-bumps. One surface of the polytetrafluoroethylene plate is fixed on a steel plate, thereby having the performances of pressure resistance and difficult breakage. The polytetrafluoroethylene plate and the steel plate are connected by adopting elastic material, thereby being capable of playing the buffer role on uneven planes and being applicable to construction fields with harsh conditions. The sliding device can bear and move thousands of tons of heavy things to designated place by sliding, thereby greatly reducing friction resistance and significantly improving sliding efficiency.

Description

technical field [0001] The invention relates to a displacement device for heavy objects in the hoisting construction process of lifting equipment. Background technique [0002] Double tower mast giant self-elevating lifting equipment is a shipbuilding gantry crane. During the hoisting process, the lifting equipment is transported to the designated position by the method of overall sliding. The lifting equipment and the plane need to be carried by devices that can withstand pressure, not deform, and have a small friction coefficient. The material used in the existing sliding device is difficult to withstand the huge pressure of heavy objects, and the frictional resistance is large. How to reduce the frictional resistance so that the sliding material does not deform or break when it is subjected to huge pressure, and can stand up on uneven ground. The buffering effect is a difficult point in the sliding construction. Contents of the invention [0003] The present invention...
