Problems solved by technology

The brake bracket of the clamp unit and the bottom of the clamp are in contact with the wooden pallet. The friction generated by the contact will affect the test results to a certain extent, which does not conform to the loading state of the clamp unit during actual use, and cannot provide accurate reference. meaningful test results

Abstract

The invention provides a clamp unit hoisting component and a clamp unit test device comprising the same. The clamp unit hoisting component comprises a cross beam, a first hoisting sub component and ahoisting plate, the first hoisting sub component and the hoisting plate are arranged two ends of the cross beam respectively, the first hoisting sub component is detachably arranged at one end of thecross beam to hoist a hoisting arm of a clamp unit, and the hoisting plate has a plate face which contacts with the cross beam and is fixedly arranged on the same. The clamp unit hoisting component can realize hoisting of a clamp unit and can really simulate state of the clamp unit after being loaded actually; the clamp unit test device can improve accuracy of a test result and meet mounting requirements of the clamp unit different in type and size and is high in universality and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of railway locomotives, and in particular relates to a clamp unit hoisting assembly and a clamp unit test device containing the assembly. Background technique [0002] The clamp unit is an important component in the braking system of railway rolling stock, and is mainly used in rolling stock such as locomotives, EMUs, and urban rails that use disc brakes. As the main component of the foundation brake, the clamp unit needs to undergo harsh environmental tests before practical application to ensure the safety of train running. [0003] The current standards involving the environmental test of the clamp unit require the clamp unit to be tested for air tightness, sensitivity, manual reset, and adjustment in a low-temperature environment, and the ambient temperature is as low as -40°C. In a low-temperature environment, the low-temperature characteristics of the brake cylinder seal or lubricating grease have a hu...
