The bearing plate is located on top of the base, and a limit frame is integrally connected to the bottom of one end of the bearing plate.

Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, and in particular to a coal electromechanical transportation device. Background Technology

[0002] Coal mining electromechanical systems are a system of integrated electromechanical technologies and equipment formed around the entire industrial chain of coal mining, processing, transportation, and utilization. The core of this system is to solve the problems of production efficiency, safety assurance, and intelligent upgrading under high-risk, high-load, and complex working conditions in the coal industry by combining mechanical structures, electrical controls, and automation systems. It is the core support for the transformation of the modern coal industry from "manual-driven" to "mechanical-driven" and "intelligent-driven".

[0003] An existing coal mining machinery installation transport device (publication number: CN222224184U) has at least the following drawbacks: The transport device in the prior art is suitable for large coal mining machinery, allowing the transport device to enter the bottom of the machinery and lift it, thus facilitating transport away from the ground. However, the space between the bottom and the ground is limited for small and medium-sized coal mining machinery, making it impossible to accommodate the transport device for lifting and transporting. Manual handling is still required, which is time-consuming and labor-intensive, resulting in low loading and unloading efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a coal electromechanical transportation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A coal conveying device includes a base, a support plate, and a downslope. A plurality of shock absorbers are fixedly connected to the top of the base, and the tops of the shock absorbers are fixedly connected to the support plate. The support plate is located on top of the base. A limit frame is integrally connected to the bottom of one end of the support plate. The inner dimensions of the limit frame are the same as the outer dimensions of one end of the base. The downslope is located at the tail end of the support plate. A drive motor is fixedly installed inside the tail end of the support plate. A transmission shaft is fixedly connected to the output end of the drive motor. One end of the transmission shaft is fixedly connected to a protrusion on the downslope and rotatably connected to the protrusion at the tail end of the support plate. Anti-slip pads are fixedly connected to the tops of both the downslope and the support plate. A front baffle is rotatably connected to the top of the end of the support plate away from the downslope via a shaft. The front baffle is located on one side of the anti-slip pads.

[0006] As a further embodiment of this utility model, the bottom of the bearing plate is provided with two sets of limiting clamps. The limiting clamps are located on one side of the shock absorber. The limiting clamps include a first clamp and a second clamp. The first clamp and the second clamp are axially symmetrically installed on the bottom of the bearing plate. Several positioning plates are integrally installed on the bottom of the bearing plate. The structure of the second clamp is the same as that of the first clamp.

[0007] As a further embodiment of this utility model, the first clamp includes a hydraulic rod, a transmission motor, a clamping plate, and a rubber pad. The tail end of the hydraulic rod is fixedly connected to the bottom of the bearing plate, and the other end of the main body of the hydraulic rod is fixedly installed on the positioning plate. The transmission motor is fixedly connected to the telescopic end of the hydraulic rod, and the output end of the transmission motor is fixedly connected to the clamping plate.

[0008] As a further embodiment of this utility model, the clamping plate is located on one side of the positioning plate, and a rubber pad is fixedly connected to the side of the clamping plate near the transmission motor. A plurality of limiting holes are opened on one side of the rubber pad, and a plurality of positioning bolts are provided on the back side of the clamping plate. The screw thread of the positioning bolt is connected to the clamping plate, and the positioning bolt matches the limiting hole.

[0009] As a further embodiment of this utility model, a set of positioning rings is provided at the bottom of the clamping plate, and the two sets of positioning rings are respectively fixedly connected to the outer sides of the base. The base is located at the bottom of the two sets of limiting clamps, and a control box is fixedly connected to the top of one side of the base. The control box is located on the side of the front baffle, and an anti-collision sleeve is integrally connected to the edge of the control box near the front baffle.

[0010] As a further embodiment of this utility model, mounting brackets are provided on both sides of the control box, and the mounting brackets are integrally connected to the top of the base. A push bracket is provided on the top of the control box, and both ends of the push bracket are inserted into the groove in the middle of the mounting bracket and rotated and connected by expansion screws. Several casters are fixedly connected to the top of the base.

[0011] Compared with the prior art, the present invention has the following beneficial effects: When loading and unloading coal mining equipment, workers start the drive motor via the control box. This starts the drive motor inside the rear end of the support plate. The motor output drives the transmission shaft to rotate, which in turn causes the downslope plate to flip downwards around the protrusion at the rear end of the support plate until the bottom of the downslope plate contacts the ground. At this point, workers use the inclined downslope plate to push the equipment from the support plate to the ground or push it onto the support plate for loading and unloading. This eliminates the need for workers to spend time and effort moving the equipment, making it easier to load and unload smaller equipment. It also avoids the need to build temporary ramps, reducing the difficulty of loading and unloading. After loading and unloading, the drive motor is started again, and the transmission shaft causes the downslope plate to flip upwards, forming a vertical position with the support plate, providing protection for the back of the equipment. If the equipment is large, the drive motor causes the downslope plate to unfold and remain at the same level as the support plate, supporting the bottom of the equipment and preventing the lack of support at the bottom from affecting the overall balance of the transport device and reducing the stability of the transport.

[0012] After the electromechanical equipment is loaded, the worker activates the limit clamps via the control box. The extension end of the hydraulic rod pushes the drive motor and clamping plate out of the bottom of the support plate. After they are moved out, the drive motor is activated, and the output end of the drive motor drives the clamping plate to rotate, making the clamping plate stand upright. At the same time, the hydraulic rod drives the clamping plate to retract again, so that the rubber pad on the inside of the clamping plate is in contact with the outer wall of the electromechanical equipment. The rubber pad has a certain degree of elasticity to prevent the clamping plate from scratching the surface of the electromechanical equipment. Meanwhile, the worker manually rotates the positioning bolt, so that one end of the positioning bolt rotates and moves the clamping pad out to press against the surface of the electromechanical equipment for clamping and positioning. The first clamp and the second clamp limit both sides of the electromechanical equipment to prevent displacement of the electromechanical equipment during transportation and to prevent it from affecting the overall balance of the transportation device.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Reference Figures 1-5A coal electromechanical conveying device includes a base 1, a bearing plate 3, and a downhill plate 4. Several shock absorbers 2 are fixedly connected to the top of the base 1, and the top of the shock absorbers 2 is fixedly connected to the bearing plate 3. The bearing plate 3 is located on the top of the base 1. A limit frame 302 is integrally connected to the bottom of one end of the bearing plate 3. The inner dimension of the limit frame 302 is the same as the outer dimension of one end of the base 1. The downhill plate 4 is located at the tail end of the bearing plate 3. A drive motor 304 is fixedly installed inside the tail end of the bearing plate 3. A transmission shaft 305 is fixedly connected to the output end of the drive motor 304. One end of the transmission shaft 305 is fixedly connected to the protrusion of the downhill plate 4 and rotatably connected to the protrusion at the tail end of the bearing plate 3. Anti-slip pads 5 are fixedly connected to the top of both the downhill plate 4 and the bearing plate 3. A front baffle 301 is rotatably connected to the top of the end of the bearing plate 3 away from the downhill plate 4 through a shaft. The front baffle 301 is located on one side of the anti-slip pad 5.

[0019] When in use, when it is necessary to load and unload coal mining machinery and equipment, the worker starts the drive motor 304 through the control box 103. The drive motor 304 inside the tail end of the bearing plate 3 starts the motor. The output end of the motor drives the transmission shaft 305 to rotate. The rotation of the transmission shaft 305 will cause the downslope plate 4 to flip down around the protrusion at the tail end of the bearing plate 3 until the bottom of the downslope plate 4 contacts the ground. At this time, the worker uses the inclined downslope plate 4 to push the machinery and equipment from the bearing plate 3 to the ground or push it along the downslope plate 4 onto the bearing plate 3 for loading and unloading. There is no need for the worker to spend time and effort to move the machinery and equipment for loading and unloading. At the same time, it avoids the need to spend time building a temporary ramp, reducing the difficulty of loading and unloading. After loading and unloading are completed, the drive motor 304 is started again, and the transmission shaft 305 drives the lower slope plate 4 to flip upward and stand vertically with the bearing plate 3, providing shielding and protection for the back of the electromechanical equipment. If the electromechanical equipment is large, the drive motor 304 drives the lower slope plate 4 to unfold and keep it on the same horizontal plane as the bearing plate 3, providing support for the bottom of the electromechanical equipment, so as to avoid the lack of support at the bottom of the electromechanical equipment affecting the overall balance of the transport device and reducing the stability of the transport.

[0020] In this embodiment, the bottom of the bearing plate 3 is provided with two sets of limiting clamps 6. The limiting clamps 6 are located on one side of the shock absorber 2. The limiting clamps 6 include a first clamp 7 and a second clamp 8. The first clamp 7 and the second clamp 8 are axially symmetrically installed on the bottom of the bearing plate 3. Several positioning plates 303 are integrally installed on the bottom of the bearing plate 3. The structure of the second clamp 8 is the same as that of the first clamp 7.

[0021] When in use, when the device moves on uneven road surfaces in a coal mine, the shock absorber 2 absorbs the impact force generated by the road bumps through its own elastic deformation, reducing the transmission of the impact force to the bearing plate 3. At the same time, the limit frame 302 limits the swaying of the bearing plate 3, preventing the bearing plate 3 from causing large-scale swaying of the electromechanical equipment and affecting the overall balance of the transport device. It also prevents equipment collisions and component loosening caused by bumps.

[0022] In this embodiment, the first clamp 7 includes a hydraulic rod 701, a drive motor 702, a clamping plate 703, and a rubber pad 704. The tail end of the hydraulic rod 701 is fixedly connected to the bottom of the bearing plate 3, and the other end of the main body of the hydraulic rod 701 is fixedly installed on the positioning plate 303. The drive motor 702 is fixedly connected to the telescopic end of the hydraulic rod 701, and the output end of the drive motor 702 is fixedly connected to the clamping plate 703.

[0023] During use, after the electromechanical equipment is loaded, the worker starts the limit clamp 6 through the control box 103. The extension end of the hydraulic rod 701 pushes the transmission motor 702 and the clamping plate 703 to move out of the bottom of the bearing plate 3. After moving out, the transmission motor 702 is started. The output end of the transmission motor 702 drives the clamping plate 703 to rotate, so that the clamping plate 703 is in an upright state. At the same time, the hydraulic rod 701 drives the clamping plate 703 to retract again, so that the rubber pad 704 on the inner side of the clamping plate 703 is attached to the outer wall of the electromechanical equipment for clamping.

[0024] In this embodiment, the clamping plate 703 is located on one side of the positioning plate 303. A rubber pad 704 is fixedly connected to the side of the clamping plate 703 near the drive motor 702. A plurality of limiting holes 705 are opened on one side of the rubber pad 704. A plurality of positioning bolts 706 are provided on the back side of the clamping plate 703. The screw thread of the positioning bolt 706 is connected to the clamping plate 703. The positioning bolt 706 matches the limiting holes 705.

[0025] During use, the rubber pad 704 has a certain degree of elasticity to prevent scratches on the surface of the electromechanical equipment when clamped by the clamping plate 703. At the same time, the worker manually rotates the positioning bolt 706, causing one end of the positioning bolt 706 to rotate and move out of the rubber pad 704 to clamp and position the electromechanical equipment. The first clamp 7 and the second clamp 8 limit the two sides of the electromechanical equipment to prevent displacement of the electromechanical equipment during transportation and affect the overall balance of the transportation device.

[0026] In this embodiment, a set of positioning rings 105 are provided at the bottom of the clamping plate 703. The two sets of positioning rings 105 are fixedly connected to the outer sides of the base 1. The base 1 is located at the bottom of the two sets of limiting clamps 6. A control box 103 is fixedly connected to the top of one side of the base 1. The control box 103 is located on one side of the front baffle 301. An anti-collision sleeve 104 is integrally connected to the edge of the control box 103 near the front baffle 301.

[0027] In use, the positioning ring 105 facilitates workers to use ropes to tie the electromechanical equipment to the bearing plate 3, thus fixing the equipment in place. When the coal-fired electromechanical equipment is loaded on top of the bearing plate 3, the front end of the equipment passively abuts against the front baffle 301 and is passively pushed by the thrust to rotate the front baffle 301 around the shaft. This causes the top of the front baffle 301 to tilt and rest on the anti-collision sleeve 104 on the top edge of the back side of the control box 103, reducing the impact force and preventing damage to the internal electronic structure of the control box 103. At the same time, the front baffle 301 and the vertical downslope plate 4 clamp and limit the front and rear sides of the equipment, preventing the equipment from shifting forward or backward during transportation.

[0028] In this embodiment, mounting brackets 101 are provided on both sides of the control box 103. The mounting brackets 101 are integrally connected to the top of the base 1. A push bracket 102 is provided on the top of the control box 103. Both ends of the push bracket 102 are inserted into the groove in the middle of the mounting bracket 101 and are rotatably connected by expansion screws. Several universal wheels 9 are fixedly connected to the top of the base 1.

[0029] When in use, the worker stretches the pusher 102. The pusher 102 rotates around the expansion bolt under the influence of external force, which makes it convenient for the worker to adjust the angle of the pusher 102 to push and pull the transport device. The universal wheels 9 at the bottom of the base 1 are subjected to force, which drives the entire base 1 device and the loaded electromechanical equipment to move and transport.

[0030] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: During loading and unloading, the worker starts the drive motor 304 at the tail end of the support plate 3 through the control box 103. The motor drives the transmission shaft 305 to rotate, causing the downslope plate 4 to flip down around the protruding post at the tail end of the support plate 3 until it touches the ground. The worker uses the inclined ramp to push the mechanical and electrical equipment for loading and unloading, without having to move the equipment or build a temporary ramp, thus reducing the difficulty. After loading and unloading, if the mechanical and electrical equipment is small and located in the support plate 3, the drive motor 304 drives the downslope plate 4 to rotate and stand upright at the tail end of the support plate 3, providing shielding and protection for the back of the equipment. If the mechanical and electrical equipment is large and exceeds the top space of the support plate 3, the drive motor 304 drives the downslope plate 4 to rotate, making the top surface of the downslope plate 4 level with the support plate 3, providing support for the bottom of the mechanical and electrical equipment to prevent imbalance. After the mechanical and electrical equipment is installed on the support plate 3, the front end of the mechanical and electrical equipment pushes against the front baffle 301, causing it to rotate around the shaft, and the top end rests on the anti-collision sleeve 104 on the back of the control box 103, reducing the impact and protecting the electronic structure. Simultaneously, the front baffle 301 and the vertical downslope plate 4 clamp the equipment to prevent forward and backward displacement during transportation. Then, the worker activates the limit clamp 6 via the control box 103. The hydraulic rod 701 pushes the drive motor 702 and clamp 703 out of the bottom of the support plate 3. The drive motor 702 drives the clamp 703 to stand upright. The hydraulic rod 701 then pulls the clamp 703 back, causing the inner rubber pad 704 of the clamp 703 to adhere to the outer wall of the equipment. The positioning bolt 706 is manually turned, allowing the end of the bolt to pass through the rubber pad 704 and position the equipment. The clamps on both sides limit the equipment's displacement. The worker stretches the push frame 102, allowing it to rotate around the expansion bolt to adjust the angle for easier pushing and pulling. The casters 9 on the base 1 drive the device and equipment to move. On uneven surfaces, the shock absorber 2 absorbs the impact force through elastic deformation, reducing the transmission to the support plate 3. The limit frame 302 restricts the swaying of the support plate 3, preventing large-scale equipment swaying from affecting balance and avoiding equipment collisions and component loosening.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
