Hydraulic self-adjusting lifting balance beam

Abstract

The invention discloses a hydraulic self-adjusting lifting balance beam which includes two main beams. The main beams are connected with each other through at least two beams, each main beam is composed of at least three connecting rods connected with each other through flange connecting plates, the beams are of a retractable box body structure, telescopic oil cylinders are arranged inside the beams, the telescopic oil cylinders are electrically connected with control modules, the tops of the main beams are provided with lifting lug plates arranged at equal distance, the bottoms of the main beams are fixedly connected with lifting plates, and lifting holes are uniformly formed in the lifting plates. According to the balance beam, the problem that the levelness and width cannot be adjustedautomatically by traditional lifting balance beams can be solved, the functions of self-adjusting and flexible disassembling and assembling of the lifting balance beam are realized, and thus lifting of steel structure modules, pipe gallery modules and eccentricity equipment assemblies with different sizes is met.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a hydraulic self-adjusting hoisting balance beam. Background technique [0002] At present, there are few domestic researches on the new hydraulic self-adjusting hoisting balance device, and the traditional hoisting method is still used for the hoisting operation of larger eccentric pipe galleries and eccentric steel structure modules, that is, by connecting shackles or using wire ropes of different lengths , or use the superposition of multi-level balance beams for hoisting operations. In special cases, hoisting is carried out by making a fixed structural balance frame or a truss-type balance beam. If a multi-level balance beam system is used for hoisting, the rigging is cumbersome, labor-intensive, and different modules are hoisted each time. and rigging connections have to be reset. If a truss-type balance beam is used for hoisting, the production cost of the truss is relatively high. Th...
