The invention discloses railway freight car static load test equipment and relates to the technical field of railway freight cars. The railway freight car static load test equipment comprises loading beams, side beams, test trolleys, an active push rod, an auxiliary push rod and a sensing device. The number of the load beams and the number of the side beams are both two. The loading beams are parallelly arranged, and the side beams are parallelly arranged. The loading beams and the side beams are arranged in a # shape. The loading beams and the side beams are connected through stop pins. The middle part of one loading beam is provided with the active push rod, and the middle part of the other loading beam is provided with the auxiliary push rod cooperated with the active push rod. The tail end of the active push rod is connected with loading beams through a hydraulic cylinder. The tail end of the auxiliary push rod is connected with the loading beams through the sensing device. The sensing device is connected with data analysis equipment. The two test trolleys are arranged just under the two loading beams respectively. The side beams are of splicing structures in the length direction. The structure is simple, the usage is safe and reliable, and the loading and unloading and the transhipment are easy.
Description
technical field [0001] The invention relates to the technical field of railway wagons. Background technique [0002] With the vigorous development of domestic rail transit, the performance requirements for vehicle components are also getting higher and higher. Freight transportation is an important part of railway transportation, and its carrying car body has a high demand for strength. The strength test of the railway freight car body is an important part of judging the overall quality of railway freight cars, which is mainly completed by static load testing equipment. Each component of the current static load testing equipment is large in size, complex in connection structure, and difficult to load, unload and transport, resulting in a long overall test cycle, which is not conducive to improving test and production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a static load test equipment for rai...
