Motor test platform

Abstract

The invention relates to a testing device of a motor, in particular to a motor test platform which comprises a butt joint guide rail and a movable platform, wherein the butt joint guide rail backward and forward extends along the butt joint direction and is arranged on the test platform, the movable platform is capable of moving on the butt joint guide rail in a guiding mode due to the fact that the movable platform is provided with a platform guide rail which fits in with the butt joint guide rail. At least two pairs of idler wheels are arranged at the bottom of the movable platform along the backward and forward direction. Rollaway nests which are used for the idler wheels to roll and move backward and forward are arranged on the test platform. Each rollaway nest is provided with steps which are used for enabling each idler wheel to drop, wherein the drop height is higher than height difference between the butt joint guide rail and the platform guide rail when the movable platform is supported on the rollaway nests through the idler wheels. A lifting mechanism is provided with the butt joint guide rail, the platform guide rail, the rollaway nests or the idler wheels, the lifting mechanism is provided with vertical displacement output and enables the idler wheels to be supported on the rollaway nests, and the butt joint guide rail and the platform guide rail move and are close to each other to form sliding fitting through the lifting mechanism or the butt joint guide rail and the platform guide rail move and separate in the opposite direction through the lifting mechanism. The motor test platform has the advantages of being capable of easily achieving transfer of the movable platform from a preparation room to a test room and butt joint when the motor test platform is used for testing.

Description

technical field [0001] The invention relates to a test device for an engine, in particular to an engine test stand. Background technique [0002] Engine performance testing is required during engine R&D and production. This test is generally carried out in an engine test room. Due to the high cost of the engine test room, its utilization rate needs to reach a high level. The test bench used in the traditional engine test room includes test equipment such as a dynamometer, and the engine bench on which the engine is installed. It takes a long time to disassemble and assemble the engine on the engine bench, and the dynamometer and the engine are installed on the engine bench. For pre-installation work such as centering and coupling butt joint, if the temperature control system, pressure control system, sensor installation, etc. are to be carried out, the pre-installation time even needs to reach 1~2 days. The test equipment is vacant during the time when the engine is on and ...

Problems solved by technology

However, the pre-installed platform system must rely on tools such as forklifts to move the pre-installed platform system to the docking rail, and the angle needs to be adjusted repeatedly to accurately place the pre-installed platform on the docking rail. The actual operation is very inconvenient. The platform and engine are also prone to accidents such as collisions and falls during the transfer process, posing safety hazards
