Problems solved by technology

At present, the hydraulic support test benches with comprehensive performance tests of hydraulic supports are all internal loading test benches, such as figure 1 As shown, it mainly includes a base 1 fixed on the foundation by anchor bolts, a column 6 fixedly connected to the base 1, and a movable beam 20 that can slide up and down on the column 6. During the test, the column 6 and the movable beam 20 pass through the bolt. Fixed connection, does not have the vertical external loading function of the hydraulic support at the same time, that is, the hydraulic support test bench only has the function of fixing the frame during the test, and cannot carry out the loading test through its own active movement
With the promotion and application of powerful hydraulic supports in high-yield and high-efficiency working faces, the existing hydraulic support test bench can no longer meet the needs of the development of hydraulic supports

Abstract

The invention discloses a vertical imposed load device of a hydraulic support, relates to the field of a test device of the hydraulic support, and aims at providing an adaptive test device for the hydraulic support. A test device for a vertical imposed load of the hydraulic support comprises a base (1), a double-spherical-hinge oil cylinder (2), a loading platform (3), a gas adjustment mechanism (4), a first guide rail (5) and a stand column (6), wherein the stand column (6) is inserted into the base (1) and is fixed in the base (1) through a hinge pin or welding; the first guide rail (5) is fixed on the stand column (6); the gap adjustment mechanism (4) is fixed on the loading platform (3); one end of the double-spherical-hinge oil cylinder (2) is fixed on the loading platform (3), and the other end of the double-spherical-hinge oil cylinder (2) is fixed in the base (1); the loading platform (3) can slide along the first guide rail (5) up and down. The test device for a vertical imposed load of the hydraulic support can perform tests of support performance and contraction allowance performance of the hydraulic support, has the characteristics of strong bias load resisting ability and gap adjustability, and can be effectively leveled.

Description

technical field [0001] The invention relates to a hydraulic support test device, in particular to a vertical external loading test device for a hydraulic support test bench. Background technique [0002] A new type of hydraulic support must undergo type inspection before it is put into use. This is a practice commonly used by countries all over the world to verify and assess the performance, reliability and safety of hydraulic support structures and components. my country's mining product safety mark management requirements All new brackets must pass the product type test organized by the national authorized inspection agency according to the relevant national standards and industry standards. The hydraulic support test bench is an essential facility for the safety supervision and inspection of the hydraulic support in the coal mine fully mechanized mining face and the factory inspection of the products of the production enterprise. It is the key testing equipment in the prod...
