Problems solved by technology
[0002] In the existing technology, large-scale road maintenance machinery such as SPZ-350x slag mixing and shaping car, DC-32Ⅳ tamping car, DCL-32x continuous tamping car and CDC-16x turnout tamping car are mainly used for railway projects. The mechanical air cylinder control gear removal test is generally carried out on the vehicle, and the realization of the gear removal and engagement action mainly depends on the air cylinder. Since the traditional method can only be carried out after loading the car, the air cylinder can only be tested and determined after the pneumatic system is completed. The pressure-holding effect, and if there is a problem with the air cylinder test, it will cause delays in the construction period and bring huge rework costs

A gear disengagement and engagement testing device is characterized in that a first supporting plate and a second supporting plate are welded in a rectangular test bed, and universal wheels are arranged at the bottom ends of four square metal stand columns of the rectangular test bed. A first double-pin pressure gauge, a second double-pin pressure gauge and a single-pin pressure gauge are sequentially and fixedly arranged on a top metal plate through bolts. A first cutout cock, a second cutout cock, a third cutout cock and a fourth cutout cock are sequentially and fixedly arranged on the first supporting plate in the rectangular test bed. A filter pressure reducing valve, a first manual valve and a second manual valve are fixedly arranged on the second supporting plate in the rectangular test bed. The filter pressure reducing valve, the first manual valve, the second manual valve, the first cutout cock, the second cutout cock, the third cutout cock, the fourth cutout cock, the first double-pin pressure gauge, the second double-pin pressure gauge, the single-pin pressure gauge and air cylinders are connected together through air pipes to form the gear disengagement and engagement testing device.
Description
technical field [0001] The invention relates to a gear removal test device, in particular to a gear removal test device controlled by an air cylinder of a large-scale railway maintenance machine. Background technique [0002] In the existing technology, large-scale road maintenance machinery such as SPZ-350x slag mixing and shaping car, DC-32Ⅳ tamping car, DCL-32x continuous tamping car and CDC-16x turnout tamping car are mainly used for railway projects. The mechanical air cylinder control gear removal test is generally carried out on the vehicle, and the realization of the gear removal and engagement action mainly depends on the air cylinder. Since the traditional method can only be carried out after loading the car, the air cylinder can only be tested and determined after the pneumatic system is completed. Pressure maintaining effect, and once there is a problem with the air cylinder test, it will cause delays in the construction period and bring huge rework costs. Co...
