Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a coal mining machine walking auxiliary mechanism suitable for complex geological conditions. Background Technology

[0002] A coal mining machine is a large, complex system integrating mechanical, electrical, and hydraulic systems. It is one of the key pieces of equipment for realizing the mechanization and modernization of coal mine production. Mechanized coal mining significantly reduces manual labor, improves work safety, and achieves high output, high efficiency, and low consumption. The application of coal mining machines not only improves the efficiency of coal mine production but also improves the working environment for miners, reducing labor costs and safety hazards.

[0003] A coal mining machine typically consists of the following main parts: a traveling mechanism, which is crucial for the machine's movement within the mining area, supporting it and enabling it to move across the coal seam; a cutting mechanism, the core of the machine, responsible for cutting the coal seam and separating the coal from it; a loading mechanism, responsible for loading the cut coal into transport equipment for delivery to a designated location; and a control system, which controls all parts of the coal mining machine, ensuring coordinated operation and achieving efficient and safe mining operations.

[0004] However, under complex geological conditions, parameters such as the height, dip angle, and hardness of coal seams vary significantly, and traditional traveling mechanisms may not be able to adequately adapt to these diverse geological conditions. This can lead to the coal mining machine malfunctioning in certain areas, and when traveling on uneven coal seams, it is prone to swaying, tilting, or even overturning. These problems not only affect the working efficiency of the coal mining machine but also increase safety hazards in the mine. Utility Model Content

[0005] To address the technical problem of coal mining machines struggling to navigate in complex geological conditions, this utility model provides a coal mining machine walking assistance mechanism suitable for complex geological conditions. This mechanism enables the coal mining machine to maintain stable movement under complex geological conditions, reduces the risk of overturning, ensures the safety of equipment and personnel, and enhances the adaptability of the coal mining machine, allowing it to operate normally in a wider range of geological conditions.

[0006] This utility model provides a walking auxiliary mechanism for a coal mining machine suitable for complex geological conditions. It includes a mounting plate, and a lifting protection groove is connected to the lower end of the mounting plate through a lifting adjustment mechanism. A track walking mechanism is installed at the lower end of the lifting protection groove. The track walking mechanism includes a motor and a connecting shaft. The outer housing of the motor is fixedly connected to a fixed plate. A fixing block is fixed in the middle of the connecting shaft. The upper end of the fixed plate and the fixing block are both fixed to the lower end of the lifting protection groove. The motor is provided with two output shafts. A first drive wheel is fixedly connected to the outer surface of each of the two output shafts. Two second drive wheels are fixedly connected to the outer surface of the connecting shaft. Tracks are rotatably connected between each of the two second drive wheels and the adjacent first drive wheel. The two tracks are symmetrically distributed.

[0007] Furthermore, the lifting adjustment mechanism includes two fixed seats and two rails. The two fixed seats and two rails are all fixedly connected to the inner bottom wall of the lifting protective groove. The two fixed seats are rotatably connected to a first connecting arm. The outer surfaces of the two rails are slidably connected to an H-shaped slide. The two H-shaped slides are rotatably connected to a second connecting arm. A first connecting rod is fixedly connected between the two second connecting arms. A first connecting seat is rotatably connected to the outer surface of the first connecting rod. A hydraulic telescopic rod is fixedly connected to one side of the first connecting seat. A second connecting rod is rotatably connected between the two first connecting arms and the two second connecting arms. A second connecting seat is rotatably connected to the outer surface of the second connecting rod. The output end of the hydraulic telescopic rod is fixedly connected to the second connecting seat.

[0008] Furthermore, each of the two first connecting arms and the two second connecting arms is rotatably connected to a connecting block at its upper end, and the upper end face of the four connecting blocks is fixedly connected to the lower end face of the mounting plate.

[0009] Furthermore, the fixing plate has an arc-shaped lower end face, which is tightly fitted and fixedly connected to the outer housing of the motor.

[0010] Furthermore, the outer surface of the track has a V-shaped pattern. This serves to increase the friction between the track and the coal seam during movement.

[0011] Furthermore, the bottom ends of the two first connecting arms are hinged to the fixed base by pins, and the bottom ends of the two second connecting arms are hinged to the H-shaped slide by pins.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) This utility model is equipped with a track walking mechanism, which has a simple structure, good adhesion of the track to the ground, large support area, and stable walking, reducing the risk of the coal mining machine overturning. At the same time, this utility model drives two tracks to walk at the same speed and trajectory, reducing the risk of yaw and walking instability, and more precise power distribution, further improving walking performance and efficiency.

[0014] (2) This utility model is equipped with a lifting and adjusting mechanism to provide stable support by adjusting the height under different conditions, so that the coal mining machine can still maintain stable movement under complex geological conditions, reduce the risk of overturning caused by excessive height, and ensure the safety of equipment and personnel. At the same time, the lifting and adjusting mechanism enhances the adaptability of the coal mining machine, and can adjust the optimal working height of the coal mining machine to ensure that the coal mining machine maintains optimal contact with the coal seam.

[0022] Example 1

[0023] Combination Figures 1-4 This utility model provides a walking auxiliary mechanism for a coal mining machine suitable for complex geological conditions, including a mounting plate 4. The lower end face of the mounting plate 4 is connected to a lifting protection groove 1 through a lifting adjustment mechanism 2. A track walking mechanism 7 is installed at the lower end of the lifting protection groove 1. The track walking mechanism 7 includes a motor 71 and a connecting shaft 72. The outer shell of the motor 71 is fixedly connected to a fixing plate 5. The fixing plate 5 has an arc-shaped lower end face, which is tightly fitted and fixedly connected to the outer shell of the motor 71. A fixing block 6 is fixed in the middle of the connecting shaft 72. The upper end faces of the fixing plate 5 and the fixing block 6 are both fixed to the lower end face of the lifting protection groove 1. The motor 71 is provided with two output shafts 73. The outer surfaces of the two output shafts 73 are fixedly connected to first drive wheels 74. The outer surface of the connecting shaft 72 is fixedly connected to two second drive wheels 75. Tracks 76 are rotatably connected between the two second drive wheels 75 and the adjacent first drive wheels 74. The two tracks 76 are symmetrically distributed and the outer surface of the tracks 76 has a V-shaped pattern.

[0024] The lifting and adjusting mechanism 2 includes two fixed seats 21 and two rails 22. Both fixed seats 21 and rails 22 are fixedly connected to the inner bottom wall of the lifting protective groove 1. Each fixed seat 21 is rotatably connected to a first connecting arm 23. Each rail 22 has an H-shaped slide block 24 slidably connected to its outer surface. Each H-shaped slide block 24 is rotatably connected to a second connecting arm 25. A first connecting rod 26 is fixedly connected between the two second connecting arms 25. A first connecting seat 27 is rotatably connected to the outer surface of the first connecting rod 26. A hydraulic telescopic rod 28 is fixedly connected to one side of the first connecting seat 27. A second connecting rod 29 is rotatably connected between the two first connecting arms 23 and the two second connecting arms 25. A second connecting seat 210 is rotatably connected to the outer surface of the second connecting rod 29. The output end of the hydraulic telescopic rod 28 is rotatably connected to the second connecting seat 210. Connecting blocks 3 are rotatably connected to the upper ends of each of the two first connecting arms 23 and the two second connecting arms 25. The upper surfaces of the four connecting blocks 3 are fixedly connected to the lower surface of the mounting plate 4.

[0025] For ease of installation, the bottom ends of the two first connecting arms 23 are hinged to the fixed base 21 by pins, and the bottom ends of the two second connecting arms 25 are hinged to the H-shaped slide 24 by pins, making installation convenient.

[0026] The working process and principle of this utility model are as follows: First, the hydraulic telescopic rod 28 is started to work. The telescopic movement of the hydraulic telescopic rod 28 drives the second connecting seat 210, which is fixedly connected to it, to move. Since the second connecting seat 210 is rotatably connected to the second connecting rod 29, and the second connecting rod 29 is also rotatably connected to the two second connecting arms 25, the second connecting rod 29 will push the two second connecting arms 25 to move around it. At the same time, the two second connecting arms 25 slide on the two track bars 22 through their respective adjacent H-shaped slides 24, and drive the first connecting rod 26 and the first connecting seat 27 to move together. At this time, the second connecting rod 29 also drives the two first connecting arms 23 on its outer surface to move on the inner walls of the two fixed seats 21. The two first connecting arms 23 and the two second connecting arms 25 rotate synchronously. The synchronous movement of the two connecting blocks 3 drives the mounting plate 4, causing the height of the mounting plate 4 to change, thereby realizing the height adjustment of the lifting and protective groove 1. Then, the motor 71 is started, and its two output shafts 73 drive the two first drive wheels 74 to rotate respectively. At the same time, the two second drive wheels 75 on the connecting shaft 72 also rotate because they are connected to the first drive wheels 74 through the track 76. When the first drive wheels 74 and the second drive wheels 75 rotate, the friction drives the track 76 to circulate between them. The track 76 contacts the ground and moves, enabling the coal mining machine installed on the mounting plate 4 to walk under complex geological conditions.

[0027] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
