Description

Technical Field

[0001] This utility model belongs to the technical field of coal mining machine rocker arm reducer maintenance, specifically relating to a coal mining machine rocker arm loading test rotating cooling water collection device. Background Technology

[0002] To verify the quality of maintenance of the rocker arm reducer of the coal mining machine, a load test is conducted on the equipment after each maintenance, based on its actual operating condition. The output end of the rocker arm has a cooling water outlet for transferring cooling water to remove heat and lower the operating temperature of the reducer. During the rocker arm reducer test, the outlet rotates with the output end. If not blocked or collected, the cooling water will splash and swirl, leading to water accumulation at the test site and posing a safety hazard over time. If the outlet is blocked during the test, the cooling water cannot flow normally and will not achieve its cooling effect. Furthermore, the load test is quite heavy and can easily generate high temperatures, making it impossible to verify the quality of the equipment maintenance. Therefore, a rotating water collection device is designed to ensure unobstructed cooling water flow during equipment testing and to collect and discharge the cooling water. Loading can be applied according to actual needs to verify product quality. Utility Model Content

[0005] The rotor is rotatably mounted inside the test device housing via positioning bearings. The two ends of the rotor are used to connect the output end of the rocker arm reducer and the input end of the water power test platform, respectively. Two floating seals are installed between the test device housing and the rotor, forming a sealed cavity between the two floating seals. A drain port is opened on the test device housing at the sealed cavity. A water inlet is provided inside the rotor. One end of the water inlet is connected to the cooling water inlet at the output end of the rocker arm reducer, and the other end is connected to the sealed cavity.

[0006] Furthermore, the test apparatus housing includes two housing floating seals, and the rotor is constructed with two support shoulders. The two floating seals are limited and mounted on the two support shoulders by the housing floating seals.

[0013] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0014] like Figure 1 As shown: A rotating cooling water collection device for a coal mining machine rocker arm loading test includes a test device housing 3 and a rotor 4. The test device housing 3 is a fixed cylinder, and the two ends of the test device housing 3 are respectively used to connect the rocker arm reducer housing 1 and the water power test platform housing.

[0015] The rotor 4 is rotatably mounted inside the test device housing 3 via a positioning bearing 8. The two ends of the rotor 4 are respectively used to connect the output end 2 of the rocker arm reducer and the input end of the water power test platform. During the rocker arm test, the rotor rotates together with the output end 2 of the rocker arm reducer and the input end of the water power test platform. Two floating seals 7 are installed between the test device housing 3 and the rotor 4, forming a sealed cavity 6 for collecting cooling water. A drain port 5 is opened on the test device housing 3 at the floating seal 6. A water nozzle is installed at the drain port 5 to discharge the cooling water through the water nozzle and the water pipe. A water inlet 4.1 is provided inside the rotor 4. One end of the water inlet 4.1 is connected to the cooling water port of the output end 2 of the rocker arm reducer, and the other end is connected to the floating seal 6, so that the cooling water is led into the sealed cavity 6 through the water inlet 4.1.

[0016] During the rocker arm test, the rocker arm motor is powered on, driving the reducer to rotate, which in turn drives the rotor 4 and the water power test platform to achieve the load test of the reducer.

[0017] During the test, the external cooling water pipe is connected to the cooling water inlet. The cooling water flows through the water channel, outlet, rotor 4, and water inlet 4.1, enters the sealed cavity 6, and is discharged through the external water nozzle, thereby achieving normal circulation of cooling water and playing a role in cooling the reducer.

[0018] The test device housing 3 includes two housing floating seals 3.1, and the rotor 4 is constructed with two support shoulders. The two floating seals 7 are limited and installed on the two support shoulders by the housing floating seals 3.1.
