Description

Technical Field

[0001] This utility model belongs to the field of coal mining machinery technology, and in particular relates to a coal mine transfer machine. Background Technology

[0002] In the process of coal mining, since coal mine tunnels are generally narrow, the traditional method is to manually excavate within the tunnels. Although this method can complete the mining of coal in a narrow space, it requires a lot of labor and is relatively inefficient.

[0003] In some large tunnels, excavators can be used for excavation, which can effectively improve excavation efficiency. However, because conventional excavators have a large working radius, they cannot complete turning operations in relatively narrow tunnels. As a result, the coal excavated in the bucket cannot be transferred to the back of the excavator, which means that the coal cannot be transported quickly. This restricts the use of conventional excavators in coal mine tunnels.

[0004] Patent application number CN202510317134.4 discloses a multi-functional transfer machine adapted to ultra-narrow coal mine roadways, comprising: a vehicle body, including a seat, a tracked walking assembly installed at the bottom of the seat, and a mounting frame fixed to the top of the seat, with a conveying space between the mounting frame and the top of the seat; an excavation mechanism, including a turntable rotatably connected to the top of the mounting frame, an excavating arm assembly installed on the turntable, and a drive component installed on the top surface of the mounting frame for driving the turntable to rotate; a material conveying mechanism, including a fixed frame installed on the top of the seat, a conveyor belt installed on the fixed frame, and a receiving platform installed at the head of the fixed frame, wherein the material conveying mechanism is located within the conveying space, a material trough is opened at one end of the receiving platform near the fixed frame, a guide plate is fixedly connected to the inner wall of the material trough on the side away from the fixed frame, and the end of the conveyor belt extends to below the guide plate; and a scraping mechanism, which is installed in the material trough and used to clean coal slag on the guide plate.

[0005] The aforementioned structure, through the cooperation between the excavating and conveying mechanisms, can easily dump the excavated coal onto a conveyor belt, which then transports it to the rear of the excavator, thus achieving rapid coal transport within a confined space. However, it suffers from the following problems during use: due to the large weight of the transfer machine and the coal being transferred, coupled with the uneven road surface in the tunnel, the tracked walking components that drive the transfer machine are prone to wear, thereby reducing the overall service life of the transfer machine.

[0006] To solve the above problems, a new type of coal mine transfer machine is needed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example

[0026] Reference Figure 1-4As shown, this embodiment provides a coal mine transfer machine, including a belt conveyor frame 1 and guide rails 2 symmetrically arranged on both sides of the belt conveyor frame 1. The top surfaces of the guide rails 2 are provided with protruding edges 3 along the length of the belt conveyor frame 1 on both sides. Each side of the belt conveyor frame 1 is connected to a guide rail 2 via a travel drive assembly, which includes a lifting drive unit and a horizontal drive unit. The lifting drive unit includes a lifting power device 4 fixed to the side of the belt conveyor frame 1. The bottom of the lifting power device 4 has a telescopic part, and the bottom of the telescopic part has a slide groove 5 that is slidably connected to the guide rail 2. A horizontal plate 6 is fixedly connected to the opening of the slide groove 5. The top surface of the horizontal plate 6 is slidably connected to the bottom surface of the protruding edge 3. The cooperation between the horizontal plate 6 and the protruding edge 3 enables the telescopic part to drive the guide rail 2 to move up and down. When the telescopic part is fully retracted, the height of the guide rail 2 is higher than the height of the bottom of the belt conveyor frame 1, and the telescopic range of the telescopic part is greater than the distance from the bottom of the telescopic part to the bottom of the belt conveyor frame 1 when the telescopic part is fully retracted.

[0027] The lifting power unit 4 can be a hydraulic cylinder. The hydraulic cylinder is connected to the oil delivery system via an oil pump. After the oil delivery system supplies oil to the hydraulic cylinder, the telescopic part on the hydraulic cylinder extends, causing the guide rail 2 to move downward and contact the roadway floor. Subsequently, the oil delivery system continues to supply oil to the hydraulic cylinder until the telescopic part is fully extended. At this time, the belt conveyor frame 1 rises and separates from the roadway floor under the action of the hydraulic cylinder. After the oil delivery system extracts the oil from the hydraulic cylinder, the telescopic part on the hydraulic cylinder retracts, causing the belt conveyor frame 1 to move downward and contact the roadway floor. Subsequently, the oil delivery system continues to extract the oil from the hydraulic cylinder until the telescopic part is fully retracted. At this time, the guide rail 2 rises and separates from the roadway floor under the action of the hydraulic cylinder.

[0028] The horizontal drive unit includes an inclined first telescopic rod 7. One end of the first telescopic rod 7 is rotatably connected to the guide rail 2, specifically to a first rotating shaft fixed on the guide rail 2. The other end of the first telescopic rod 7 is rotatably connected to the belt conveyor frame 1, specifically to a second rotating shaft fixed on the belt conveyor frame 1. Both the first and second rotating shafts are horizontally arranged and perpendicular to the material conveying direction of the belt conveyor frame 1.

[0029] The first telescopic rod 7 can be a hydraulic cylinder. The hydraulic cylinder is connected to the oil delivery system through an oil pump. After the oil delivery system supplies oil to the hydraulic cylinder, the length of the first telescopic rod 7 increases. After the oil delivery system extracts the oil from the hydraulic cylinder, the length of the first telescopic rod 7 decreases. The change in the length of the first telescopic rod 7 causes a relative displacement between the guide rail 2 and the belt conveyor frame 1.

[0030] In operation, the telescopic part on the lifting power device 4 first extends, causing the guide rail 2 to descend and contact the roadway ground, while the belt conveyor frame 1 rises and separates from the ground. Then, the first telescopic rod 7 extends, causing the bottom of the telescopic part to slide on the guide rail 2, achieving relative movement between the belt conveyor frame 1 and the guide rail 2, i.e., the forward movement of the belt conveyor frame 1. Subsequently, the telescopic part on the lifting power device 4 retracts back to its original position, causing the belt conveyor frame 1 to descend and contact the roadway ground, while the guide rail 2 rises and separates from the ground. Then, the first telescopic rod 7 returns to its original position, causing the guide rail 2 to slide within the chute 5, achieving relative movement between the guide rail 2 and the belt conveyor frame 1, i.e., the forward movement of the guide rail 2. This completes the forward movement of the entire coal mine transfer machine.

[0031] In a further preferred embodiment, a belt conveyor assembly is provided on the top of the belt conveyor frame 1. The belt conveyor assembly includes a front roller 8, an upper support roller 9, and a first guide roller 10, which are rotatably connected to the top surface of the top plate of the belt conveyor frame 1 along its length. One end of the first guide roller 10 is connected to a belt drive motor, and multiple upper support rollers 9 are provided. The belt conveyor assembly also includes a second guide roller 11 and several lower support rollers 12, which are rotatably connected to the bottom surface of the top plate of the belt conveyor frame 1 along its length. The second guide roller 11 is arranged parallel to and directly below the first guide roller 10. The front roller 8, upper support roller 9, first guide roller 10, second guide roller 11, and lower support rollers 12 are all arranged perpendicular to the conveying direction of the belt conveyor frame 1, and are all connected to the belt conveyor frame 1 via a conveyor belt.

[0032] When in use, the conveyor belt is fitted onto the front roller 8, the upper support roller 9, the first steering roller 10, the second steering roller 11, and the lower support roller 12. The upper support roller 9 and the lower support roller 12 can support the conveyor belt. The front roller 8 transmits the power of the belt drive motor to the conveyor belt, so that the conveyor belt can run, thereby achieving stable transportation of coal in the mine.

[0033] In a further preferred embodiment, both ends of the front roller 8 are rotatably connected to the first bearings within the first bearing housing 13, and the first bearing housing 13 is slidably connected to the top surface of the top plate of the belt conveyor frame 1. The first bearing housing 13 is connected to the first horizontal drive assembly 14, which provides power for the movement of the first bearing housing 13 on the top plate of the belt conveyor frame 1. The first horizontal drive assembly 14 drives the first bearing housing 13 to slide on the top plate of the belt conveyor frame 1, thereby driving the front roller 8 to move.

[0034] A translation roller 15 is rotatably connected to the bottom surface of the top plate of the belt conveyor frame 1. The translation roller 15 is also connected to the conveyor belt. Specifically, the conveyor belt is arranged as follows: it extends from the side of the first steering roller 10 away from the front end roller 8, wraps around the translation roller 15 on the side near the front end roller 8, and then wraps around the side of the second steering roller 11 away from the front end roller 8. The translation roller 15 is located between the second steering roller 11 and the lower support roller 12 located near the second steering roller 11, and the height of the translation roller 15 from the ground is lower than that of the first steering roller 10 but higher than that of the second steering roller 11. Both ends of the translation roller 15 are rotatably connected to the second bearings in the second bearing housing 16. The second bearing housing 16 is slidably connected to the top plate of the belt conveyor frame 1 and is connected to the second horizontal drive assembly 17. The second horizontal drive assembly 17 drives the second bearing housing 16 to slide on the top plate of the belt conveyor frame 1, thereby driving the translation roller 15 to move.

[0035] When in use, the translation roller 15 moves along the conveying direction of the coal mine, and the front roller 8 moves in the opposite direction of the conveying direction of the coal mine. At this time, the front end position of the conveyor belt can be adjusted without the belt conveyor frame 1 being stationary, which is convenient for use. When in use, it should be noted that the moving speed of the front roller 8 driven by the first horizontal drive component 14 is twice the moving speed of the translation roller 15 driven by the second horizontal drive component 17, so as to ensure the stability of the conveyor belt.

[0036] In a further preferred embodiment, the first horizontal drive assembly 14 includes a second telescopic rod 141 fixed on the belt conveyor frame 1. The second telescopic rod 141 is parallel to the length direction of the belt conveyor frame 1. A transmission rod 142 is fixedly connected to the end of the telescopic part of the second telescopic rod 141. The transmission rod 142 is fixedly connected to the first bearing seat 13.

[0037] In use, the second telescopic rod 141 can be a hydraulic cylinder. After the first telescopic rod 7 extends, it drives the first bearing seat 13 to move in the opposite direction along the coal mine conveying direction. After the first telescopic rod 7 extends and retracts, it drives the first bearing seat 13 to move along the coal mine conveying direction, thereby realizing the movement of the front roller 8.

[0038] In a further preferred embodiment, the second horizontal drive assembly 17 includes a rack 171 and a guide groove 172 fixed parallel to the belt conveyor frame 1. The rack 171 is parallel to the length direction of the belt conveyor frame 1. The rack 171 meshes with a gear 173, which is fixed to the output shaft of a translation drive motor 174. The translation drive motor 174 is fixedly connected to a second bearing housing 16, which is slidably connected within the guide groove 172.

[0039] In use, the translation drive motor 174 drives the gear 173 to rotate, so that the gear 173 moves along the length direction of the rack 171. At this time, the translation drive motor 174 and the second bearing seat 16 move synchronously with the gear 173, thereby realizing the movement of the translation roller 15.

[0040] In a further optimized design, limit blocks 18 are fixedly connected to both ends of the guide rail 2, and the height of the limit blocks 18 gradually increases from the end closer to the guide rail 2 to the end farther away from the guide rail 2.

[0041] When in use, the limiting block 18 can limit the movement of the guide rail 2 or the belt conveyor frame 1, preventing the guide rail 2 from coming out of the slide 5, and thus preventing the guide rail 2 from separating from the belt conveyor frame 1.

[0042] In a further optimized design, a roller is rotatably connected to the chute 5 via a horizontally set rotating shaft. The rotating shaft is perpendicular to the length direction of the belt conveyor frame 1, and the bottom of the roller contacts the top surface of the guide rail 2.

[0043] When in use, the rollers can reduce the frictional resistance and wear between the slide 5 and the guide rail 2.

[0044] In a further optimized design, a lifting frame 19 is fixedly connected to the conveying start end of the belt conveyor frame 1. A robotic arm 20 with a bucket is movably connected to the top surface of the lifting frame 19. A material conveying area is provided between the bottom surface of the lifting frame 19 and the conveyor belt. The robotic arm 20 is used to collect coal and place it on the material conveying area. The structure of the robotic arm 20 is common in existing technologies and will not be elaborated upon here.

[0045] Therefore, this utility model adopts the above-mentioned structure of a coal mine transfer machine, which utilizes a lifting drive unit and a horizontal drive unit to divide the overall movement of the equipment into two parts: the belt conveyor frame 1 and the guide rail 2. This reduces the friction between the equipment and the roadway floor, thereby reducing the wear of the equipment and improving its service life.

[0046] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0047] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
