Description

Technical Field

[0001] This utility model relates to the field of underground mining equipment technology, and in particular to a coal retaining wall and a coal conveyor with a motor-driven universal wheel reversing mechanism. Background Technology

[0002] The conveyor is a key component of the conveying equipment. When the coal mining machine is excavating the coal face, the conveyor propels the machine forward, and coal slides onto the conveyor, ending at the tail of the machine. During this process, coal chunks or gangue from the coal face may fall onto the machine body or tail. Excessive accumulation at the tail can easily damage the coal mining conveyor and may also cause injury to personnel underground. To improve the service life of the conveyor, it is necessary to improve the coal mining equipment to protect the tail section. Summary of the Invention

[0003] In order to solve the technical problems existing in the above-mentioned technologies, it is necessary to provide a solution. A coal retaining wall with a motor-driven omnidirectional wheel reversing mechanism includes a support chassis and a coal retaining wall mechanism mounted on the support chassis. The bottom of the supporting chassis is rotatably equipped with casters that allow the supporting chassis to move. The coal retaining wall mechanism includes a coal retaining plate and a support assembly. The lower end of the coal retaining plate is hinged to the upper end of the support base. The upper end of the support assembly is rotatably connected to the upper part of the coal retaining plate on the side away from the coal wall. The lower end of the support assembly extends away from the support base and contacts the ground, so that the lower end of the support assembly is resisted by the ground and avoids movement, ensuring that the coal retaining plate is inclinedly arranged above the support base.

[0004] Preferably, the support assembly includes a telescopic part and a ground-fixing part; the upper end of the telescopic part is rotatably connected to the upper part of the coal retaining plate away from the coal wall, the lower end of the telescopic part is fixedly connected to the upper end of the ground-fixing part, and the lower end surface of the ground-fixing part is in contact with the ground, so that the lower end surface of the ground-fixing part is resisted by the ground and thus avoids movement.

[0005] Preferably, the lower end face of the ground fixing part is flush with the ground fixing part, and the side end face of the ground fixing part away from the supporting chassis is perpendicular to the lower end face of the ground fixing part, so that a blocking ridge is formed between the lower end face and the side end face of the ground fixing part.

[0006] Preferably, the side of the ground fixing part facing the supporting chassis has a slope that slopes away from the supporting chassis, so that this side of the ground fixing part forms a conical structure.

[0007] Preferably, the lower end of the side face away from the supporting chassis of the ground fixing part is fixedly provided with an anti-slip claw that is flush with the lower end face of the ground fixing part.

[0012] It is also necessary to provide a coal mining conveyor.

[0013] A coal mining conveyor includes the aforementioned motor-driven omnidirectional coal retaining wall.

[0014] Compared with existing technologies, the coal retaining wall and coal conveyor with motor-driven universal wheels provided by this utility model include a supporting chassis and a coal retaining wall mechanism installed on the supporting chassis. Universal wheels are rotatably installed at the bottom of the supporting chassis to move the supporting chassis. The coal retaining wall mechanism includes a coal retaining plate and a supporting component. The lower end of the coal retaining plate is hinged to the upper end of the supporting chassis, and the upper end of the supporting component is rotatably connected to the upper part of the coal retaining plate on the side away from the coal wall. The lower end of the supporting component extends away from the supporting chassis and contacts the ground, so that the lower end of the supporting component is prevented from moving due to ground resistance, ensuring that the coal retaining plate is inclinedly arranged above the supporting chassis. By using a universal wheel-driven supporting chassis, the coal retaining wall mechanism can move forward, backward, left, and right, adjusting the position of the coal retaining plate, ensuring that fallen coal or gangue can be quickly cleared, preventing the chassis from jamming, and solving the problem of difficult-to-clean coal accumulation in the coal retaining wall.

Detailed Implementation

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] Please refer to Figures 1 to 3 In one embodiment, the present invention provides a coal retaining wall with a motor-driven universal wheel reversing mechanism, including a support chassis 01 and a coal retaining wall mechanism 02 installed on the support chassis 01. The support chassis 01 is equipped with omnidirectional casters 03 at its bottom. These casters allow the support chassis 01 to change direction, enabling the coal retaining wall mechanism 02 to move forward, backward, left, and right. By steering the casters 03, the overall position of the coal retaining wall mechanism 02 can be adjusted, ensuring that falling coal or gangue is quickly cleared and preventing the chassis from jamming. The steering control via the casters 03 reduces the overall installation space of the coal retaining wall mechanism 02, improving its utilization rate in the underground space. The casters 03 are driven by a motor to achieve movement and direction changes.

[0025] The coal retaining wall mechanism 02 includes a coal retaining plate 21 and a support component 22. The lower end of the coal retaining plate 21 is hinged to the upper end of the support chassis 01. The upper end of the support component 22 is rotatably connected to the upper part of the coal retaining plate 21 on the side away from the coal wall. The lower end of the support component 22 extends to the side away from the support chassis 01 and contacts the ground, so that the lower end of the support component 22 is prevented from moving due to ground resistance, thus ensuring that the coal retaining plate 21 is inclinedly arranged above the support chassis 01.

[0026] In one embodiment, the support assembly 22 includes a telescopic part 221 and a ground-fixing part 222. The upper end of the telescopic part 221 is rotatably connected to the upper part of the coal retaining plate 21 on the side away from the coal wall, and the lower end of the telescopic part 221 is fixedly connected to the upper end of the ground-fixing part 222. The lower end face of the ground-fixing part 222 contacts the ground, so that the lower end face of the ground-fixing part 222 is prevented from moving due to ground resistance. The length of the telescopic part 221 is adjustable. When the telescopic part 221 extends or retracts, the angle between the support assembly 22 and the coal retaining plate 21 can be adjusted, thereby controlling the tilt angle of the coal retaining plate 21. Of course, the telescopic part 221 can be any one of a hydraulic cylinder, an electric telescopic rod, or a pneumatic cylinder. The above structures and methods are all prior art and will not be described in detail here.

[0027] In this design, the ground-fixing part 222 can be installed in two different ways. The first method involves directly contacting the lower end face of the ground-fixing part 222 with the ground surface. The lower end face of the ground-fixing part 222 has a rectangular structure, which increases the contact area with the ground. The resistance provided by the large contact surface between the ground-fixing part 222 and the ground ensures that the support component 22 will not move. The second method involves embedding the lower end of the ground-fixing part 222 into the ground for fixation; a recess in the ground can be pre-drilled to allow the ground-fixing part 222 to embed.

[0028] Specifically, the lower end face of the ground fixing part 222 is flush with the ground, and the side end face of the ground fixing part 222 away from the supporting chassis 01 is perpendicular to the lower end face of the ground fixing part 222, so that a blocking ridge 223 is formed between the lower end face and the side end face of the ground fixing part 222. When the coal retaining plate 21 is impacted by falling coal, the blocking ridge 223 can prevent the ground fixing part 222 from sliding relative to the ground, so as to ensure the stability of the support; and when the lower end of the ground fixing part 222 is driven into the reserved pit, the blocking ridge 223 can block the ground fixing part 222 from the side to prevent slippage.

[0029] The ground fixing part 222 has a slope that slopes away from the support chassis 01 on the side facing the support chassis 01, forming a conical structure on this side of the ground fixing part 222, which can reduce the weight of the ground fixing part 222.

[0030] Of course, to increase the resistance between the lower end face of the ground fixing part 222 and the ground surface, several small cones can be added to the lower end face of the ground fixing part 222.

[0031] Please refer to Figure 4 In one embodiment, the lower end of the ground fixing part 222 on the side away from the supporting chassis 01 is fixedly provided with an anti-slip claw 04 that is flush with the lower end surface of the ground fixing part 222.

[0032] Of course, to increase the stability and anti-slip effect, the anti-slip claws 04 can be arranged at equal intervals along the length of the ground fixing part 222.

[0033] Specifically, the anti-slip claw 04 includes a connecting part 41 and a gripping part 42. The connecting part 41 is detachably installed on the lower end of the side face of the ground fixing part 222 away from the supporting chassis 01. The left end of the gripping part 42 is connected to the connecting part 41, and the right end of the gripping part 42 is bent towards the lower end face of the ground fixing part 222, and the right end of the gripping part 42 is flush with the lower end face of the ground fixing part 222. The gripping part 42 can cooperate with the blocking edge 223 to further prevent the ground fixing part 222 from slipping relative to the ground, so as to ensure the stability of the support. When the lower end of the ground fixing part 222 is inserted into the reserved groove, the gripping part 42 can be inserted into the ground to enhance the stability of the fixation.

[0034] The gripping part 42 and the connecting part 41 are integrally formed, and the gripping part 42 and the connecting part 41 are arranged at an obtuse angle.

[0035] The right end of the gripping part 42 has a conical structure.

[0036] Please refer to Figure 5 The coal retaining plate 21 has a rubber pad on its coal-retaining side surface. The rubber pad can reduce the direct impact of coal blocks on the coal retaining plate 21, providing a certain buffering effect, while also preventing the coal blocks from abrading the coal retaining plate 21.

[0037] In one embodiment, the present invention provides a coal mining conveyor, including a coal retaining wall with a universal wheel driven by the motor for reversing direction.

[0038] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
