Description

Technical Field

[0001] This utility model belongs to the field of coal mine transportation technology, specifically referring to a residual coal transportation device. Background Technology

[0002] Currently, during the transportation of coal, workers need to first shovel the coal into a coal transport cart, then transport it to a designated location before unloading it. The unloading operation is usually carried out by rotating the cart with a cylinder. The unloading height is fixed and cannot be flexibly adjusted according to actual working conditions (such as storage bins of different heights or differences in the material receiving port height of transport vehicles).

[0003] In practical applications, if the storage silo is high or the height of the receiving vehicle changes, the device that fixes the unloading height may have difficulty accurately unloading the residual coal to the target position, which may lead to the residual coal spilling and accumulating. This not only wastes materials but also increases cleaning costs and safety hazards, affecting unloading efficiency and operational safety. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the existing technology, this utility model provides a residual coal transportation device, which effectively solves the problem of not being able to flexibly adjust the unloading height.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A residual coal transportation device includes a fixed base plate and a transportation trolley. A vertical support side plate is fixed on one side of the fixed base plate. Vertical grooves are provided on both sides of the support side plate. A threaded column is rotatably provided in the groove. A drive motor is installed on the top of the support side plate. The output end of the drive motor is connected to the threaded column. A movable base plate is threadedly connected to the threaded column. The movable base plate slides vertically relative to the support side plate through the groove. Two sets of symmetrical U-shaped brackets are rotatably connected to one end of the movable base plate. A cylinder is hinged between the bracket and the movable base plate. Two sets of inclined limiting grooves are fixed at the bottom center of the bracket. The transport trolley is placed on the movable base plate and fixed columns with horizontal through-limiting grooves are fixed on both side walls. A limiting end block is provided at one end of the fixed column.

[0006] Preferably, the cylinder body end of the cylinder is hinged to the side wall of the movable base plate, and the piston rod end is hinged to the bottom of the bracket.

[0007] Preferably, one end of the movable base plate is fixed with an inclined guide plate, the inclined angle of the guide plate is 10°-20°, and the end is smoothly connected to the upper surface of the movable base plate.

[0008] Preferably, the inclination angle of the limiting groove is 15°-30°.

[0009] Preferably, the drive motor is a geared motor with a self-locking function.

[0010] The beneficial effects achieved by adopting the above-described structure are as follows: 1. By setting a support side plate on one side of the fixed base plate, the drive motor drives the threaded column to rotate, so that the moving base plate can slide vertically along the groove, thereby accurately adjusting the unloading height. Whether unloading to a higher storage silo or docking with transport vehicles of different heights, it can be easily adapted, greatly improving the versatility and applicability of the device. 2. The transport trolley is limited by a combination of U-shaped brackets and limiting grooves. When the brackets lift the transport trolley, the fixed column on the transport trolley falls into the inclined bottom of the limiting groove under its own weight. The limiting groove provides a reliable limit to the fixed column, effectively preventing the transport trolley from shaking or shifting during unloading, and ensuring a smooth and safe unloading process.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0015] like Figure 1-4 As shown, the present invention proposes a residual coal transportation device, including a fixed base plate 1 and a transportation trolley 2. A vertical support side plate 3 is fixed on one side of the fixed base plate 1. Vertical grooves 4 are provided on both sides of the support side plate 3. Threaded columns 5 are rotatably provided in the grooves 4. A drive motor 6 is installed on the top of the support side plate 3. The output end of the drive motor 6 is connected to the threaded column 5. The drive motor 6 is a reduction motor with self-locking function and is electrically connected to the controller, so that the lifting process of the movable base plate 7 is more stable and slower, and it is convenient for the operator to accurately adjust the unloading height according to actual needs. The movable base plate 7 is threadedly connected to the threaded column 5. The movable base plate 7 slides vertically relative to the support side plate 3 through the grooves 4. like Figure 1 , 2 As shown in Figure 4, two sets of symmetrical U-shaped brackets 8 are rotatably connected to one end of the movable base plate 7. A cylinder 9 is hinged between the bracket 8 and the movable base plate 7. The cylinder body end of the cylinder 9 is hinged to the side wall of the movable base plate 7, and the piston rod end is hinged to the bottom of the bracket 8. Two sets of inclined limiting grooves 10 are fixed at the bottom center of the bracket 8. The inclination angle of the limiting grooves 10 is 15°-30°. When the cylinder 9 drives the bracket 8 to flip and unload, it ensures that the trolley is always in the correct position. The transport trolley 2 is placed on the movable base plate 7 and fixed columns 11 that are horizontally penetrating the limiting grooves 10 are fixed on both side walls. A limiting end block 12 is provided at one end of the fixed column 11.

[0016] like Figure 1-4 As shown, an inclined guide plate 13 is fixed at one end of the movable base plate 7. The inclined angle of the guide plate 13 is 10°-20°, and its end is smoothly connected to the upper surface of the movable base plate 7. This ensures that the transport trolley 2 can slide smoothly onto the movable base plate 7 by its own weight or a small external force, while avoiding the trolley's downward speed from being too fast and difficult to control due to the excessive angle.

[0017] In practical use, the transport trolley 2 containing residual coal is pushed along the inclined guide plate 13 onto the movable base plate 7. The fixed column 11 on the transport trolley 2 is aligned with the limiting groove 10 at the bottom center of the U-shaped bracket 8. When the bracket 8 completely lifts the transport trolley 2, the fixed column 11 falls into the inclined bottom of the limiting groove 10 under the action of the transport trolley 2's own weight. The limiting groove 10 limits the fixed column 11, thereby completing the fixation of the transport trolley 2.

[0018] Based on the actual unloading requirements, determine the target unloading height, start the drive motor 6, which drives the threaded column 5 to rotate. The threaded column 5 is threadedly connected to the movable base plate 7, causing the movable base plate 7 to slide vertically along the grooves 4 on both sides of the support side plate 3. After adjusting the movable base plate 7 to a suitable height, turn off the drive motor 6 and start the cylinder 9. The piston rod of the cylinder 9 extends, causing the bracket 8 to rotate around its hinge point with the movable base plate 7, thereby causing the transport trolley 2 to tilt. The residual coal is unloaded from the transport trolley 2 under the action of gravity and falls into the target location (such as a storage bin or transport vehicle). After unloading is completed, control the cylinder 9 to reverse its movement, so that the transport trolley 2 returns to its initial horizontal state. To increase flexibility and convenience, multiple casters are installed at the bottom of the fixed base plate 1, and the casters are equipped with brakes.

[0019] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
