Abstract

The invention provides a test device for a hopper vehicle bottom door and an opening-closing mechanism. The test device is composed of a supporting frame, a bottom door mounting base, a baffle, a bottom door, an opening and closing mechanism and first driving cylinders. The bottom door mounting base and the support frame are fixedly connected. The baffle is arranged at the side along the longitudinal direction of the bottom door mounting base. The baffle is arranged on the support frame; a discharge port is formed between the baffle and the bottom door mounting base; and the bottom door is arranged at the discharge port. The two ends of the bottom door are connected with the bottom door mounting base and the baffle respectively. The opening and closing mechanism is arranged on the bottom door mounting base and is connected with the bottom door. The first driving cylinders are arranged in a direction perpendicular to the bottom door; cylinder rod parts of the first driving cylinders are connected with the bottom door in a spherical hinge manner; and the cylinder body parts of the first driving cylinders are connected with the support frame in a spherical hinge manner. Therefore, the opening and closing forces of the hopper vehicle bottom door can be increased and accuracy of the fatigue intensity test result of the opening and closing mechanism is improved.

Description

technical field [0001] The invention belongs to the technical field of railway funnel car test devices, in particular to a test device for a bottom door of a funnel car and an opening and closing mechanism. Background technique [0002] Since the bottom door of the hopper car and the opening and closing mechanism are the core components of the hopper car, in order to ensure the stability of the operation of the hopper car, according to the standard AAR S-233-2014 "Technical Conditions for the New Gravity Unloading Port of the Covered Funnel Car", It is necessary to test the opening and closing force of the bottom door of the hopper car and the fatigue strength of the opening and closing mechanism. [0003] However, the existing test device for the bottom door of the hopper car and the opening and closing mechanism can only simulate the working environment of the bottom door of the hopper car and the opening and closing mechanism of the hopper car under the condition of no lo...
