Description

Technical Field

[0001] This utility model belongs to the technical field of coal mining equipment, specifically, it relates to a driving device for a horizontal loading coal bunker conveyor belt. Background Technology

[0002] In coal mining operations, horizontal coal bunker conveyor belts play a crucial role in transporting coal from the mining face to storage areas or other transportation stages. Traditional mining horizontal coal bunker conveyor belt drive systems mostly employ a single motor drive.

[0003] This horizontal coal bunker represents a significant improvement over conventional horizontal coal bunkers in its belt drive system. It applies the "clamping-pushing" drive principle of hydraulic cylinders to the belt drive, a method widely used in hydraulic belt winding devices. Our company has improved and optimized this design, effectively reducing belt damage by rationally controlling the clamping force while ensuring stable, non-slipping belt movement. The drive actuator is a hydraulic cylinder, powered by a hydraulic pump station. The pump station's drive motor power is significantly reduced compared to conventional coal bunkers, greatly contributing to lower operating costs. By reducing motor power and eliminating the need for a bulky reducer, the amount of tunnel excavation work can be reduced when laying horizontal coal bunkers, lowering labor intensity and construction costs.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To address the significant improvements made to the belt drive system of this horizontal coal bunker compared to conventional horizontal coal bunkers, the "clamping-pushing" drive principle of hydraulic cylinders is applied to the belt drive. This drive method is widely used in hydraulic belt winding devices. Our company has improved and optimized this method, effectively reducing belt damage by reasonably controlling the clamping force while ensuring stable and non-slipping during belt pushing. The drive actuator of this type of drive is a hydraulic cylinder, powered by a hydraulic pump station. The power of the pump station's drive motor is significantly reduced compared to the drive motor power of conventional coal bunkers, greatly contributing to reducing enterprise operating costs. Due to the reduced motor power and the elimination of the bulky reducer, the amount of tunnel excavation work can be reduced when laying horizontal coal bunkers in coal mines, thus reducing the labor intensity of workers and construction costs. The basic concept of the technical solution adopted by this utility model is:

[0006] A driving device for a horizontal loading coal bunker conveyor belt in a mine includes a support frame and a conveyor belt mounted on the support frame. A base plate is provided on one side of the support frame, and a clamping cylinder and a pushing cylinder are provided above the base plate. The clamping cylinder is used to clamp the conveyor belt, and the pushing cylinder is used to push the clamping cylinder to move.

[0007] In a preferred embodiment of this utility model, a loading bin is provided above the conveyor belt, a loading end is provided on one side of the loading bin, a first support roller is connected to the bottom end of the loading bin, a guide rail is connected to the top surface of the bottom plate, rollers are rolled on the guide rail, a connecting shaft is connected between the rollers, an upper clamping crossbeam is connected to both ends of the connecting shaft, the bottom end of the clamping cylinder is installed on the top surface of the upper clamping crossbeam, and the output end of the clamping cylinder is connected to the lower clamping crossbeam.

[0008] In a preferred embodiment of this utility model, a fixed horizontal plate is connected to the inner side of the support rods on both sides of the base plate, a first hinge seat is connected to the outer wall of the fixed horizontal plate, one end of the push cylinder is movably mounted on the first hinge seat, the output end of the push cylinder is movably mounted on a second hinge seat, one side of the outer wall of the second hinge seat is connected to the outer side of the upper clamping crossbeam, and a second support roller is movably mounted at the bottom end of the base plate.

[0009] In a preferred embodiment of the present invention, there are several first support rollers, which are evenly and equidistantly distributed at the bottom of the loading bin, and the top surface of the first support rollers is attached to and supported on the bottom of the conveyor belt.

[0010] In a preferred embodiment of this utility model, the lower belt surface of the conveyor belt is disposed between the upper clamping beam and the lower clamping beam.

[0011] In a preferred embodiment of this utility model, the extension and retraction of the output end of the push cylinder constitutes one push stroke.

[0012] In a preferred embodiment of this utility model, the number of the pushing cylinders is two, and the pushing cylinders are symmetrically distributed on the outer walls of both sides of the upper clamping crossbeam.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This invention utilizes a hydraulic cylinder to move the lower clamping beam upwards, bringing it closer to the upper clamping beam. The upper and lower clamping beams then clamp the lower surface of the conveyor belt. Subsequently, a pushing cylinder moves both beams to the right, causing the upper surface of the conveyor belt to move to the left, thus moving the conveyor belt and completing the material transport. The entire drive system is powered by a hydraulic pump station, which significantly reduces the power of the pump station's drive motor compared to conventional coal bunker drive motors, greatly contributing to lowering enterprise operating costs.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0024] like Figures 1 to 5 As shown, a conveyor belt drive device for a horizontal loading coal bunker in a mine includes a support 1 and a conveyor belt 2 installed on the support 1. A base plate 6 is provided on one side of the support 1, and a clamping cylinder 11 and a pushing cylinder 15 are provided above the base plate 6. The clamping cylinder 11 is used to clamp the conveyor belt 2, and the pushing cylinder 15 is used to push the clamping cylinder 11 to move.

[0025] Furthermore, a loading bin 3 is provided above the conveyor belt 2, and a loading end 4 is provided on one side of the loading bin 3. A first support roller 5 is connected to the bottom end of the loading bin 3. A guide rail 7 is connected to the top surface of the bottom plate 6. Rollers 8 are rolled on the guide rail 7. A connecting shaft 9 is connected between the rollers 8. An upper clamping crossbeam 10 is connected to both ends of the connecting shaft 9. The bottom end of the clamping cylinder 11 is installed on the top surface of the upper clamping crossbeam 10. The output end of the clamping cylinder 11 is connected to the lower clamping crossbeam 12.

[0026] Furthermore, there are several first support rollers 5, which are evenly and equidistantly distributed at the bottom of the loading bin 3. The top surface of the first support rollers 5 is attached to the bottom of the upper surface of the conveyor belt 2. By setting multiple first support rollers 5, the upper surface of the conveyor belt 2 can be supported, thereby ensuring that the material can be transported normally.

[0027] Furthermore, the lower belt surface of the conveyor belt 2 is positioned between the upper clamping beam 10 and the lower clamping beam 12, which allows the lower clamping beam 12 to move upward and cooperate with the upper clamping beam 10 to clamp the lower belt surface of the conveyor belt 2.

[0028] The inner sides of the support rods on both sides of the base plate 6 are connected to a fixed horizontal plate 13. The outer wall of the fixed horizontal plate 13 is connected to a first hinge seat 14. One end of the outer wall of the pushing cylinder 15 is movably mounted on the first hinge seat 14. The output end of the pushing cylinder 15 is movably mounted on a second hinge seat 16. One side of the outer wall of the second hinge seat 16 is connected to the outer side of the upper clamping crossbeam 10. The bottom end of the base plate 6 is movably mounted on a second support roller 17.

[0029] Furthermore, the extension and retraction of the output end of the push cylinder 15 constitutes one push stroke, thereby repeatedly controlling the push cylinder 15 to extend and retract, thus driving the conveyor belt 2 to move.

[0030] Furthermore, there are two pushing cylinders 15, which are symmetrically distributed on the outer walls of both sides of the upper clamping beam 10. This allows for uniform support of the upper clamping beam 10 from both sides, ensuring uniform stability during movement.

[0031] The implementation principle of a mine horizontal loading coal bunker conveyor belt drive device in this embodiment is as follows: The lower belt surface of the conveyor belt 2 is placed between the upper clamping beam 10 and the lower clamping beam 12. Then, the material is placed on the conveyor belt 2. Subsequently, the clamping cylinder 11 is activated, and its output end will drive the lower clamping beam 12 to move upward, so that the lower clamping beam 12 and the upper clamping beam 10 gradually approach each other. In this way, the conveyor belt 2 placed between the two can be clamped. After the lower belt surface of the conveyor belt 2 is clamped, the pushing cylinder 15 is activated, and its output end will extend, and then push the roller 8 to move on the guide rail 7. As the roller 8 moves, it will drive the upper clamping beam 10, the lower clamping beam 12, and the clamping cylinder 11 to move. With the movement of the three, the lower belt surface of the clamped conveyor belt 2 can be driven to move to the right. Moving to the right will cause the upper belt to move to the left, thus conveying the material on its top surface. This completes one push stroke. After completing one push stroke, the clamping cylinder 11 can be activated to extend the output end downward, thereby moving the lower clamping beam 12 downward and moving it away from the upper clamping beam 10. This releases the clamping limit on the lower surface of the conveyor belt 2. Then, the push cylinder 15 is activated to retract its output end, moving the upper clamping beam 10 and the lower clamping beam 12 back to their initial positions before starting the next push stroke. This process is repeated to push the conveyor belt 2 until the entire loading bin 3 is filled with material. The power source for this entire drive system is provided by a hydraulic pump station. The power of the pump station's drive motor is significantly reduced compared to the drive motor power of a conventional coal bin, which greatly helps to reduce the company's operating costs.
