Embodiment Construction

[0014] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0015] Such as figure 1 , 2 As shown, the large-scale test hanger provided in this embodiment is mainly composed of a hook connecting part 9, an upper welded box 7, a weight frame 1, and upper and lower pulley assemblies. The upper and lower pulley assembly is made of pulley frame 3, block pulley 5 and steel wire rope 6. The upper welded box type is a frame structure with a hollow in the middle, and a mounting frame 10 is connected to the middle position of the top, and the hook connecting part is connected to the mounting frame through a pin shaft 11 . The four corners of the mounting bracket are respectively connected with one end of the slanting brace 8 by pins, and the other end of the slanting brace is connected with the convex plate 12 on the upper welding box type by pins. The four corners of the upper welding box bottom are provided with the pulley frame 3 ...

Abstract

The invention relates to a large test run hanging bracket with adjustable balance weight space. The large test run hanging bracket comprises a lifting hook connecting component, an upper welding box pile, a weight rack and steel wire ropes, and is characterized in that upper and lower pulley assemblies are correspondingly arranged at the four corners of the bottom of the upper welding box pile and the four corners of the surface of the weight rack respectively; the steel wire ropes are wound at the positions between pulley sets of the corresponding upper and lower pulley assemblies, and the length of the steel wire ropes can be adjusted; and weight rack extending arms are connected to the peripheral side walls of the weight rack respectively, wherein a 90-degree included angle is formed between the folded weight rack extending arms and the weight rack, and the weight rack extending arms and the weight rack are located on the same plane when the weight rack extending arms are put down. According to the test run hanging bracket, the balance weight arrangement space can be increased or reduced according to needs, the requirements for different balance weights are met, and the equipment cost is reduced; the size of the weight rack is reduced by means of folding of the weight rack extending arms, and the requirement for highway transport can be met; and the structure is simple, mounting and demounting are convenient, and maintenance is facilitated.

Description

technical field [0001] The invention relates to a mechanical hoisting device, in particular to a large-scale test hanger with adjustable counterweight space for nuclear industry construction. Background technique [0002] In the process of nuclear power plant construction, in order to ensure the safety of the construction, the lifting equipment must be tested for load before hoisting work on the construction site. [0003] At present, the existing test run hangers are generally designed according to the weight to be hoisted in nuclear power construction. A test run hanger of one specification can only carry the corresponding counterweight due to the limitation of the counterweight installation space. When it is heavy, it is necessary to replace the test run hanger of another specification, and configure the test run hanger of different specifications, which increases the equipment cost and brings inconvenience to transportation. [0004] The Chinese invention patent disclos...
