Description

Rotary cooling water collecting device for loading test of rocker arm of coal mining machine Technical Field The utility model belongs to the technical field of overhauling of a rocker arm speed reducer of a coal mining machine, and particularly relates to a rotary cooling water collecting device for a loading test of a rocker arm of the coal mining machine. Background In order to verify the overhaul quality of the rocker arm speed reducer of the coal mining machine, after each overhaul is completed, loading test is carried out on the equipment according to the actual running condition of the equipment. The output end of the rocker arm of the coal mining machine is provided with an output port of a cooling water channel for transmitting cooling water so as to take away heat and reduce the operating temperature of the speed reducer. When the rocker arm speed reducer is tested, the water outlet rotates along with the output end, if the rocker arm speed reducer is not plugged or collected, cooling water flies along with the output end and swings around, accumulated water in a test site can be accumulated for a long time, potential safety hazards exist, if the rocker arm speed reducer is tested, the water outlet is plugged, the cooling water cannot normally circulate and cannot play a role of cooling, in addition, the load is high in a loading test, high temperature is extremely easy to generate, equipment maintenance quality cannot be verified, and therefore the rotary water collecting device is designed, not only can a smooth cooling water channel be ensured in the equipment test, but also cooling water can be collected and led out, loading can be carried out according to actual requirements, and the product quality is verified. Disclosure of utility model The utility model aims to solve the problem that internal cooling water is thrown around in the test of the rocker arm speed reducer of the coal mining machine. The utility model provides a rotary cooling water collecting device for a loading test of a rocker arm of a coal mining machine, which comprises a test device shell and a rotor, wherein the test device shell is a fixed cylinder, and two ends of the test device shell are respectively used for connecting a rocker arm speed reducer shell and a water power test platform shell; The rotor is rotatably assembled in the test device shell through the positioning bearing, two ends of the rotor are respectively used for connecting the output end of the rocker arm speed reducer and the input end of the water power test platform, two floating seals are arranged between the test device shell and the rotor, a sealing cavity is formed between the two floating seals, a water outlet is formed in the test device shell at the sealing cavity, a water diversion hole is formed in the rotor, one end of the water diversion hole is communicated with a cooling water gap of the output end of the rocker arm speed reducer, and the other end of the water diversion hole is communicated with the sealing cavity.
