Novel free fall test system

Abstract

The invention discloses a novel free fall test system, comprising a top plate, a rectangular frame and a fixing seat, wherein the rectangular frame is fixedly connected to the top of the top plate, acylinder is fixedly connected to the bottom of the top plate, an upright post is fixedly connected to a position at the bottom of the top plate located at the middle of the cylinder, a balancing weight matching the cylinder is movably connected to the top of the surface of the upright post, and the invention relates to the technical field of mine equipment. In the novel free fall test system, shells are movably connected to both sides of the top of the balancing weight and the both sides of the upright post, thereby facilitating the free fall of the balancing weight, the operation is simple, the reactive force is small, a free fall test can be conveniently carried out, a rotating rod is rotationally connected between the both sides of an inner wall of the rectangular frame, so that the fall height of the balancing weight can be conveniently adjusted according to the test requirements, and the balancing weight is unlikely to generate an offset phenomenon during the free fall, such thata derrick is not affected by the balancing weight, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the technical field of mine equipment, in particular to a novel free-fall test system. Background technique [0002] A mine is a general term for the shafts, chambers, equipment, ground buildings and structures that form the underground coal mine production system. Sometimes the inclined shafts, vertical shafts, and flat pits in the underground development of mines are also called mines. The size of the mine field of each mine 1. Determination of mine production capacity and service life is one of the key issues that must be solved in the design of the mine itself. The mine production capacity generally refers to the design production capacity of the mine. The original production capacity of some production mines needs to be changed due to various reasons, so It is necessary to re-verify the capacity of each production system of the mine. The comprehensive production capacity after verification is called the verified production c...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a new type of free fall test system, which solves the problem that it is inconvenient to realize the automatic falling of objects, the reaction force is relatively large, and the operation is cumbersome. There is a severe vibration, which poses a great safety hazard
