Description

Technical Field

[0001] The utility model relates to the field of equipment testing for mining vehicles, in particular to a motor cover testing machine for mining vehicles. Background Art

[0002] In mining, mine cars are often used for operations, and the motors of mine cars are usually installed on the tires, which makes the motors easily damaged by the impact of flying ore when the mine cars are in operation. Therefore, a motor cover is needed to protect it. The installation of existing motor covers needs to take into account the road conditions in the mining area. When the mine car passes over speed bumps or ditches, the mine car will have a sudden drop and rise. Therefore, it is necessary to simulate the environment and test whether the motor cover can be firmly connected to the mine car in this environment. The existing test device only simulates the vibration of the motor, and the vibration amplitude is not large, and it is impossible to achieve a real simulation effect. Therefore, a motor cover tester for mine cars is needed. Utility Model Content

[0015] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0017] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0018] See also Figure 1-2 A motor cover testing machine for a mine car comprises a base 1, on which a simulation mechanism 2 is provided, and a motor cover 3 is installed on the simulation mechanism 2 through a bracket, and the connection between the bracket and the motor cover 3 is the connection method between the mine car and the motor cover 3. The simulation mechanism 2 comprises a motor 21, and a transmission rod 22 is rotatably connected to the inside of the base 1 through a cross bar, and a pulley 23 is fixedly connected between the transmission rod 22 and the transmission shaft of the motor 21, and a turntable 24 is fixedly connected at both ends of the transmission rod 22, and a slide rod 25 is fixedly connected to the opposite sides of the two turntables 24, and each slide rod 25 is slidably connected to a U-shaped frame 26, and the ends of the two U-shaped frames 26 are slidably connected to a turntable 28, which is connected to the motor cover 3, and the bottom of the turntable 28 is rotatably connected to a support shaft 29, which is fixedly connected to the base 1, and grooves are provided on both sides of the base 1 near the turntable 24. When in use, the initial positions of the two slide bars 25 are different. When viewed from the side, they are one left and one right, and the rotation direction is the same. The operator controls the motor 21 to start, and the motor 21 drives the transmission rod 22 to rotate through the pulley 23, and the transmission rod 22 drives the two turntables 24 to rotate. The two turntables 24 respectively drive the U-shaped frame 26 to move up and down reciprocatingly through the slide bars 25. Since the movement trajectory of the two slide bars 25 is half of the turntable 24, when the U-shaped frame 26 on one side moves upward, the U-shaped frame 26 on the other side moves downward, and so on. The two U-shaped frames 26 drive the turntable 28 to swing rapidly left and right with the support shaft 29 as the center, so that the motor cover 3 swings rapidly left and right. When the turntable 28 swings, it touches the base 1, thereby simulating the real bumpy vibration scene of the mine car when passing through the ditch, and testing whether the motor cover 3 can still be firmly connected to the mine car tire when the mine car passes the speed bump or ditch. The scene simulation has high realism and significant effect.

[0019] In some embodiments, armrests 11 are provided on both sides of the base 1. When the operator needs to carry the mobile device, the armrests 11 can be used for support, helping the operator to carry and transfer, which is very convenient.

[0020] In some embodiments, spring feet 12 are provided at the bottom of the base 1. The spring feet 12 can provide a support buffer for the base 1 when the rotating plate 28 is flipped, which not only increases the overall shaking degree of the device and provides a realistic simulation environment, but also reduces the impact of the base 1 on the ground, preventing ground damage.

[0021] In some embodiments, rubber rods 13 are provided on the grooves on both sides of the base 1 near the turntable 24. The rubber rods 13 not only cushion the turntable 28 to prevent damage caused by collision with the base 1, but also give the turntable 28 a vibration feeling, thereby improving the realism of the simulation.

[0022] In some embodiments, the rotating plate 28 is provided with a slide groove 281, which is slidably connected to the U-shaped frame 26. When the rotating plate 28 is deflected by the U-shaped frame 26, the end of the U-shaped frame 26 slides on the slide groove 281, which can maximize the deflection of the rotating plate 28, impart vibration to the motor cover 3, and improve the realism and reliability of the simulation.

[0023] In some embodiments, a limit frame 27 is provided inside the base 1 near the side of the U-shaped frame 26. The limit frame 27 not only guides the U-shaped frame 26, but also limits the U-shaped frame 26 to prevent the U-shaped frame 26 from tilting and causing errors in the operation of the device.

[0024] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
