Embodiment Construction

[0024] The claw testing equipment of the present invention will be further described in detail below in conjunction with the accompanying drawings. A claw testing device, comprising a jack 4, a lower anchor head 3, a loading hydraulic cylinder 2 and a test frame 1; the jack 4 is arranged outside the test frame 1, and the lower anchor head 3 and the loading hydraulic cylinder 2 are arranged Inside, the jack 4 is fixedly connected to the lower anchor head 3 through the steel strand 5, one end of the loading hydraulic cylinder 2 is connected to the lower anchor head 3, and the other end of the loading hydraulic cylinder 2 is fixedly connected to the test frame 1, as figure 1 shown.

[0025] In the jaw test equipment, the jack 4, the lower anchor head 3 and the steel strand 5 are all parts of the existing hydraulic lifting device, and the jack 4, the lower anchor head 3 and the loading hydraulic cylinder 2 are arranged on a straight line. When some hydraulic lifting devices are i...

Abstract

The invention provides a claw test instrument and a claw test system. The claw test instrument comprises a jack (4), a lower anchor head (3), a loading hydraulic cylinder (2) and an experimental frame (1), wherein the jack (4) is arranged at the outer side of the experimental frame (1), and the lower anchor head (3) and the loading hydraulic cylinder (2) are arranged at the inner side of the experimental frame (1). The claw test system further comprises a hydraulic pump station and a centralized-control box. The claw test instrument and the claw test system are of horizontal gantry structures so as to avoid the risk of aloft work. A traditional load block loading manner is replaced by a hydraulic loading manner, a fatigue life test can be performed on multiple pairs of jaws at the same time, the infinite loop work of ascending with loads and descending with the loads is achieved in the test process, and the jaw test efficiency is improved. By adopting the novel test instrument, the labor intensity can be reduced, and the whole test process can be finished by only one worker.

Description

technical field [0001] The invention relates to the technical field of jaw testing equipment, in particular to jaw testing equipment, and a jaw testing system including the jaw testing equipment. Background technique [0002] At present, in the fields of electric power construction and construction engineering, more and more super-high, super-large and over-weight large-scale building components need to be assembled on the ground and then upgraded as a whole. The hydraulic lifting device is a new type of special lifting equipment. The claw is an important load-bearing component on the hydraulic lifting device, which transmits the load of the suspended object to the jack through the steel strand. Once the jaws are damaged or fail, the consequences will be extremely serious. [0003] The force of the claws has the following characteristics: large force, taking a steel strand with a diameter of 15.2mm as an example, the force of each pair of claws is 90kN; Load conversion mu...
