Description

Technical Field

[0001] This utility model belongs to the technical field of mine transport carts, and particularly relates to a mine transport cart. Background Technology

[0002] Mine transport trolleys refer to the collective term for transport vehicles and operations used in underground or surface auxiliary transport processes in mines to move ore, gangue, equipment, materials, and personnel along tracks, driven by human, mechanical, or electric power. They are an important component of the mine transport system, primarily addressing the short-distance transfer of materials and personnel within the mine, connecting key stages such as mining, tunneling, and hoisting, and ensuring the timely supply of production materials and the smooth removal of ore.

[0003] Currently, while existing mine transport carts can effectively transport coal, unloading is often difficult. The cart is typically tilted to dump the material, but this often results in material buildup requiring multiple movements of the cart to empty completely, or the use of external tools to remove the material. This not only reduces unloading efficiency but also increases the effort required, significantly impacting the cart's usability.

[0004] Therefore, we propose a mine transport trolley to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem of inconvenient unloading in the prior art, and to propose a mine transport trolley.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mine transport trolley includes a fixed frame, a material frame slidably connected to the inner wall of the fixed frame, a rotating shaft rotatably connected to the inner wall of the fixed frame, two winding drums fixedly connected to the outer surface of the rotating shaft, a steel wire rope sleeved inside each winding drum, and the bottom end of each steel wire rope fixedly connected to the upper surface of the material frame. A first servo motor is fixedly connected to the front of the rotating shaft, and the right side of the first servo motor is fixedly connected to the left side of the fixed frame. A second servo motor is fixedly connected to both the front and back of the material frame, and a gear is fixedly connected to the power output end of each second servo motor. An opening and closing door is slidably connected to the inner wall of the material frame, and racks are fixedly connected to both the front and back of the opening and closing door. The outer surface of each rack meshes with the outer surface of a gear.

[0008] Preferably, the bottom surface of the fixed frame is fixedly connected to four casters, and the outer surface of the fixed frame is fixedly connected to two counterweights.

[0009] Preferably, a handle is fixedly connected to the left side of the fixed frame, and an anti-slip pad is fixedly connected to the outer surface of the handle.

[0010] Preferably, two lamp holders are fixedly connected to the upper surface of the fixed frame, and a lighting lamp is fixedly connected to the bottom surface of each lamp holder.

[0011] Preferably, a reinforcing ring is fixedly connected to the outer surface of each lamp holder, and the bottom surface of each reinforcing ring is fixedly connected to the upper surface of the fixed frame.

[0012] Preferably, the upper surface of the fixed frame is fixedly connected to two support wheels, and the inner wall of each support wheel is in contact with the outer surface of the wire rope.

[0013] Preferably, the inner wall of the fixed frame is rotatably connected to four limiting wheels, and the inner wall of each limiting wheel is in contact with the outer surface of the wire rope.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] By setting up a first servo motor, a rotating shaft driven by the first servo motor, and a winding drum, in conjunction with the steel wire rope connecting the material frame, stable lifting and lowering of the material frame within a fixed frame can be achieved. During unloading, there is no need to tilt the entire trolley; the unloading height can be adjusted simply by raising and lowering the material frame, avoiding multiple trolley movements caused by material accumulation and significantly improving unloading efficiency. At the same time, the opening and closing door design at the bottom of the material frame, in conjunction with the second servo motor, gears, and racks, enables automated opening and closing of the door. Material can be discharged directly from the bottom of the material frame under gravity, without the need for external tools to scrape the material. This reduces the labor intensity of workers and the number of operational steps during the unloading process, further improving unloading efficiency. In addition, the overall structure achieves automated operation through mechanical transmission, ensuring stable and reliable operation and reducing the uncertainty caused by manual intervention. This helps improve the overall safety and continuity of mine transportation operations and allows for raising the unloading height as needed, such as directly raising the material frame to a certain height and unloading the material onto the conveyor belt for transport.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A mine transport trolley includes a fixed frame 1, a material frame 2 slidably connected to the inner wall of the fixed frame 1, a rotating shaft 10 rotatably connected to the inner wall of the fixed frame 1, four universal wheels 3 fixedly connected to the bottom surface of the fixed frame 1, and two counterweights 4 fixedly connected to the outer surface of the fixed frame 1. The four universal wheels 3 allow the trolley to flexibly turn and move in the narrow and complex space of the mine, greatly improving the flexibility of transportation and making it convenient for workers to adjust the direction of travel of the trolley according to actual needs. The two counterweights 4 can effectively lower the center of gravity of the trolley, enhance the stability of the trolley after loading materials, avoid dangerous situations such as tipping over due to an excessively high center of gravity, and ensure the safety of the transportation process.

[0023] Two winding drums 11 are fixedly connected to the outer surface of the rotating shaft 10. Each winding drum 11 is fitted with a steel wire rope 12. A handle 5 is fixedly connected to the left side of the fixed frame 1. An anti-slip pad 6 is fixedly connected to the outer surface of the handle 5. The handle 5 provides a convenient point of force for workers to push or pull the cart, making it easy to control the movement of the cart. The anti-slip pad 6 increases the friction between the hand and the handle 5. Even in the humid environment inside the mine, workers can firmly hold the handle 5, preventing the cart from slipping and becoming out of control, thus improving the reliability of operation.

[0024] The bottom end of each wire rope 12 is fixedly connected to the upper surface of the material frame 2. The front of the rotating shaft 10 is fixedly connected to the first servo motor 13. The right side of the first servo motor 13 is fixedly connected to the left side of the fixed frame 1. Two lamp holders 7 are fixedly connected to the upper surface of the fixed frame 1. Each lamp holder 7 has a lighting lamp 8 fixedly connected to its bottom surface. Since the interior of the mine is usually dimly lit, the lighting lamps 8 supported by the two lamp holders 7 can provide sufficient lighting around the cart, illuminating the transportation path and work area, making it easier for workers to observe the road conditions, material conditions and the surrounding environment, reducing accidents such as collisions and falls caused by poor visibility, and improving the safety and efficiency of the operation.

[0025] A second servo motor 16 is fixedly connected to both the front and back of the material frame 2. A gear 18 is fixedly connected to the power output end of each second servo motor 16. A reinforcing ring 9 is fixedly connected to the outer surface of each lamp holder 7. The bottom surface of each reinforcing ring 9 is fixedly connected to the upper surface of the fixed frame 1. The reinforcing ring 9 further strengthens the connection between the lamp holder 7 and the fixed frame 1, so that the lamp holder 7 can remain stable even if it encounters bumps or vibrations during the movement of the trolley, and prevents the lighting lamp 8 from being damaged or falling off due to the shaking or loosening of the lamp holder 7, thus ensuring the continuous and stable operation of the lighting function.

[0026] The inner wall of the material frame 2 is slidably connected to an opening and closing door 17. The front and back of the opening and closing door 17 are fixedly connected to racks 19. The upper surface of the fixed frame 1 is fixedly connected to two support wheels 14. The inner wall of each support wheel 14 is in contact with the outer surface of the wire rope 12. The support wheel 14 provides good support for the wire rope 12, changes the force angle of the wire rope 12, avoids the wire rope 12 from directly rubbing against the edge of the fixed frame 1, reduces the wear of the wire rope 12, extends the service life of the wire rope 12, and also ensures the smoothness of the wire rope 12 during the winding and unwinding process, ensuring that the material frame 2 can be raised and lowered smoothly.

[0027] The outer surface of each rack 19 meshes with the outer surface of the gear 18. The inner wall of the fixed frame 1 is rotatably connected with four limiting wheels 15. The inner wall of each limiting wheel 15 is in contact with the outer surface of the wire rope 12. The four limiting wheels 15 can accurately limit the position of the wire rope 12, preventing the wire rope 12 from deviating or tangling during the winding and unwinding process, ensuring that the wire rope 12 always moves along the preset trajectory, thereby ensuring the accuracy and stability of the lifting and lowering of the material frame 2, and avoiding problems such as tilting of the material frame 2 and material falling due to the deviation of the wire rope 12.

[0028] The working principle of this utility model is as follows: When in use, the staff first connects the first servo motor 13, the second servo motor 16 and the lighting lamp 8 to the external power supply and controller, then pours the coal into the material frame 2, and then pushes and transports the material to the designated area through the handle 5, and then unloads the material as needed.

[0029] The controller starts the first servo motor 13, which drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the two winding drums 11 to rotate synchronously. The winding drums 11 wind up the wire rope 12, and the wire rope 12 pulls the material frame 2 to rise in the fixed frame 1. When the material frame 2 rises to a suitable height, the first servo motor 13 is turned off.

[0030] At this time, the second servo motor 16 is started by the controller. The second servo motor 16 drives the gear 18 to rotate. The gear 18 meshes with the rack 19 and drives the opening and closing door 17 to slide open. The coal in the material frame 2 is discharged from the opening and closing door 17 under the action of gravity, completing the unloading. After the unloading is completed, the second servo motor 16 is started again to reverse and close the opening and closing door 17. Then the first servo motor 13 is started to reverse and lower the material frame 2 to reset, ready for the next loading. The entire unloading process does not require tilting the entire cart. It can be achieved by raising and lowering the material frame 2 and adjusting the opening and closing of the opening and closing door 17. The operation is simple and quick, which greatly improves the unloading efficiency and safety. The surface of the opening and closing door 17 has a fixed sealing gasket to seal the gap between the opening and closing door 17 and the material frame 2.
