Problems solved by technology

At present, the NSW type hand brake test device can be divided into two categories, one type is simple in structure, but its operation is complicated, and cannot fully meet the performance test requirements of NSW type hand brake; the other type requires the NSW type hand brake The test can only be carried out after assembly and loading on the vehicle. Because of the high installation seat of the hand brake, it may bring safety hazards to the workers, and may also affect the hand brake performance of the NSW type hand brake after loading, resulting in the failure of railway freight cars. Safety hazards in parking or shunting operation

Abstract

The invention relates to a manual brake test device and a use method of the manual brake test device. The manual brake test device comprises a bracket, wherein a fixed plate is perpendicularly arranged on one end of the bracket, four bolt holes are formed in the fixed plate at intervals, the lower part of the fixed plate is provided with an opening, and a steering gear is arranged at the opening; and the other end of the bracket is connected with one end of a tension spring, the other end of the tension spring is connected with one end of an adjustment pull rod, and the other end of the adjustment pull rod is connected with a first chain lifting ring by a first round pin. The manual brake test device and the use method of the manual brake test device have the advantages of simplicity in structure, easiness in operation and good safety performance, and can be widely used for the performance tests on NSW type manual brakes of rail wagons.

Description

technical field [0001] The invention relates to a test device and its use method, in particular to a railway wagon NSW type hand brake test device and its use method. Background technique [0002] NSW hand brake is a device that uses manpower to turn the hand wheel to make the brake shoe press the wheel of the railway freight car to achieve the purpose of braking, and it is used for parking or shunting. NSW type hand brake has the functions of braking, relief and force regulating braking. In order to ensure the good performance of the hand brake of the railway freight car, the performance test of the NSW type hand brake is required before the NSW type hand brake is overhauled and loaded. At present, the NSW type hand brake test device can be divided into two categories, one type is simple in structure, but its operation is complicated, and cannot fully meet the performance test requirements of NSW type hand brake; the other type requires the NSW type hand brake The test ca...
