The invention discloses a center-of-gravity-adjustable counterweight tooling used for the test of a support vehicle in a coal mine, relates to the technical field of roadway transportation, and solves the problem of how to simulate the position of the center of gravity of multiple types of hydraulic supports in the prior art to test the transport adaptation of the support vehicle Technical issues of sex and maximum transport slope. It includes a base, a fence and several counterweights, the fence is fixedly installed on the base, the base has a first direction distributed along the horizontal, the base and the fence cooperate to form at least two accommodating cavities arranged along the first direction, and several counterweights are arranged in a row It is stacked in the storage cavity, and the hook hanging point is fixed along the periphery of the base, and the hook hanging point is used for the tooling to be lifted and transferred. By adjusting the center of gravity of the tooling, various working conditions can be tested on the ground by simulating the vehicle carrying the target bracket, which improves the safety and reliability of the vehicle's underground operation, and it is also convenient to adjust the weight of the counterweight to adapt to various weight hydraulic supports underground.
Description
technical field [0001] The invention relates to the technical field of roadway transportation, in particular to a center-of-gravity-adjustable counterweight frock for the test of a support truck in a coal mine. Background technique [0002] The hydraulic support truck is a special transportation equipment specially used for long-distance transportation or reverse transportation of the hydraulic support during the retraction and installation process of the fully mechanized mining face in the coal mine. In recent years, with the continuous development of fully mechanized mining technology, the types of hydraulic supports used for the support and management of the roof of the working face have been increasing, and the height of the support has been increasing. The weight and structural size of the hydraulic supports are constantly changing. The change, such as the chopping bracket, the position of the center of gravity is very rearward, and it is easy to cause the front wheel o...
