Description

Technical Field

[0001] This utility model relates to the technical field of vehicle cover tarpaulin devices, and more particularly to material vehicle cover tarpaulin devices. Background Technology

[0002] In industrial sectors such as coal mining, material transport vehicles are indispensable transportation tools in daily operations. To ensure safety and environmental protection during transportation, covering the materials on the transport vehicles is a necessary measure.

[0003] In practical use, traditional covering methods mostly involve manually laying tarpaulins. This method is not only inefficient, but also poses safety hazards under inclement weather conditions. In addition, coal mine material transport vehicles tend to accumulate dust and dirt on the vehicle body and the loaded materials during long-term use, requiring regular cleaning and maintenance. Traditional cleaning methods also rely on manual operation, which is not only time-consuming and labor-intensive, but also difficult to guarantee the cleaning effect. Therefore, it is necessary to improve the automatic unfolding and storage of the covering tarpaulins and achieve efficient cleaning functions.

[0004] Therefore, to address the aforementioned inconveniences in automatically unfolding and retracting the tarpaulin and achieving efficient cleaning, a material transport vehicle tarpaulin device can be designed. During use, the drive motor first rotates the gear via the drive shaft. The drive gear meshes with the fixed gear plate, causing the guide block to slide parallel on the guide rod. The movement of the guide block further pulls one end of the connecting bracket to move horizontally along the guide rod, while the other end of the connecting bracket moves synchronously parallel via a sliding component. This series of mechanical actions causes one end of the tarpaulin to unfold horizontally, thus automatically and smoothly unfolding the entire tarpaulin to form a sealed cover for the material transport vehicle. Simultaneously with the unfolding of the tarpaulin, the connecting bracket also carries the water pipe, which moves parallel to the material transport vehicle. The water pipe is connected to a water pump via a connecting hose, which is rotated, unfolded, and extended using a connecting component. This design ensures that the water pipe can extend as the tarpaulin unfolds. The device extends to prepare for subsequent cleaning work. When the material transport vehicle needs cleaning, the water pump is started, and water is drawn in and delivered through the pumping pipe to the connecting hose, then flows through the water supply pipe to the spray pipes on both sides. At this time, the pressure valves on both sides are opened, and high-pressure water is sprayed out through multiple sets of spray heads to efficiently clean both sides of the material transport vehicle. After the covering or cleaning task is completed, the drive motor is started, which drives the drive gear to reverse through the drive shaft. The reverse drive gear drives the connecting bracket to move in the opposite direction through the fixed tooth plate, thereby causing the covering tarpaulin and the water supply pipe to retract in the opposite direction. By installing the assembly, the covering tarpaulin can be rotated and wrapped for storage. At the same time, by connecting the assembly, the connecting hose can be rotated and wrapped for storage. The entire device returns to its initial state, ready for the next use. In summary, this device not only realizes the automatic unfolding and storage of the covering tarpaulin, but also integrates a high-efficiency cleaning function, greatly improving the operating efficiency and practicality of coal mine material transport vehicles. Utility Model Content

[0005] To address the challenges of using vehicle cover tarpaulins, traditional methods often involve manually laying the tarpaulin, which is inefficient and poses safety hazards in inclement weather. Furthermore, coal mine material transport vehicles accumulate dust and dirt on the vehicle body and loaded materials over long periods, requiring regular cleaning and maintenance. Traditional cleaning methods also rely on manual operation, which is time-consuming, labor-intensive, and ineffective. Therefore, improvements are urgently needed to address the issues of automatically unfolding and retracting the tarpaulin and achieving efficient cleaning.

From there, it flows through the delivery pipe to the spray pipes on both sides. At this time, the pressure valves on both sides are opened, and high-pressure water is sprayed out through multiple spray nozzles to efficiently clean both sides of the material transport vehicle. After the covering or cleaning task is completed, the drive motor is started, which drives the drive gear to reverse through the drive shaft.

By using the installation component, the covering tarpaulin can be rotated and wrapped for storage. At the same time, by using the connecting component, the connecting hose can be rotated and wrapped for storage. The entire device returns to its initial state, ready for the next use.

The drive gear meshes with the fixed gear plate, causing the guide block to slide parallel on the guide rod. The movement of the guide block further pulls one end of the connecting bracket to move horizontally along the guide rod, while the other end of the connecting bracket moves synchronously parallel via a sliding component.

The other end of the connecting hose 15 is rotated and wound around and stored under the action of the connecting spiral spring 304.

[0026] During the use of the tarpaulin device, firstly, the drive motor 7 is started, which drives the gear 9 to rotate via the drive shaft 8. The drive gear 9 meshes with the fixed toothed plate 10, thereby causing the guide block 4 to slide parallel on the guide rod 3. The movement of the guide block 4 further pulls one end of the connecting bracket 19 to move horizontally along the guide rod 3, while the other end of the connecting bracket 19 moves synchronously parallel on the sliding rod 102 via the sliding block 103. This series of mechanical actions causes one end of the tarpaulin 11 to unfold in parallel. At the same time, the other end of the tarpaulin 11, connected to the mounting spiral spring 204 via the mounting shaft 203, achieves reverse rotation during the unfolding of the tarpaulin, thereby automatically and smoothly unfolding the entire tarpaulin to form a sealed cover for the material transport vehicle 1.

[0027] As the tarpaulin 11 unfolds, the connecting bracket 19 also supports the parallel movement of the water pipe 16. The water pipe 16 is connected to the water pump 13 via a connecting hose 15. The connecting hose 15 is rotated, unfolded, and extended using the connecting shaft 303 and its connecting spiral spring 304. This design ensures that the water pipe 16 can extend as the tarpaulin 11 unfolds, preparing for subsequent cleaning work.

[0028] When it is necessary to clean the material transport vehicle 1, the water pump 13 is started, and water is drawn in and delivered through the water pumping pipe 14 to the connecting hose 15, and then flows through the water delivery pipe 16 to the spray pipes 17 on both sides. At this time, the pressure valves 5 on both sides are opened, and high-pressure water is sprayed out through multiple sets of spray heads 18 to efficiently clean both sides of the material transport vehicle 1.

[0029] After completing the covering or cleaning task, the drive motor 7 is restarted, which drives the drive gear 9 to reverse via the drive shaft 8. The reversed drive gear 9, through the fixed gear plate 10, drives the connecting bracket 19 to move in the opposite direction, thereby causing the covering tarpaulin 11 and the water pipe 16 to retract in the opposite direction. The other end of the covering tarpaulin 11 is rotated and wound back under the action of the installed spiral spring 204. At the same time, the connecting hose 15 is also rotated and wound back under the action of the connecting spiral spring 304. The entire device returns to its initial state, ready for the next use.

[0030] In summary, this device not only enables the automatic unfolding and storage of the tarpaulin 11, but also integrates a highly efficient cleaning function, greatly improving the operating efficiency and practicality of the coal mine material transport vehicle 1.

[0031] Through the above steps, during the use of the tarpaulin device, firstly, the drive motor 7 is started, which drives the gear 9 to rotate via the drive shaft 8. The drive gear 9 meshes with the fixed toothed plate 10, thereby causing the guide block 4 to slide parallel on the guide rod 3. The movement of the guide block 4 further pulls one end of the connecting bracket 19 to move horizontally along the guide rod 3, while the other end of the connecting bracket 19 moves synchronously in parallel through the sliding component. This series of mechanical actions causes one end of the tarpaulin 11 to unfold in parallel, thus automatically and smoothly unfolding the entire tarpaulin to form a sealed cover for the material transport vehicle 1. While the tarpaulin 11 unfolds, the connecting bracket 19 also carries the water pipe 16, which moves in parallel. The water pipe 16 is connected to the water pump 13 through the connecting hose 15, and the connecting hose 15 is rotated, unfolded, and extended using the connecting component. This design ensures that the water pipe 16 can extend as the tarpaulin 11 unfolds, preparing for subsequent cleaning work. When cleaning materials is required... When transporting vehicle 1, the water pump 13 is started, water is drawn in and delivered through the water pumping pipe 14 to the connecting hose 15, and then through the water delivery pipe 16 to the spray pipes 17 on both sides. At this time, the pressure valves 5 on both sides are opened, and high-pressure water is sprayed out through multiple sets of spray heads 18 to efficiently clean both sides of the material transport vehicle 1. After the covering or cleaning task is completed, the drive motor 7 is started, which drives the drive gear 9 to reverse through the drive shaft 8. The reversed drive gear 9 drives the connecting bracket 19 to move in the opposite direction through the fixed tooth plate 10, thereby driving the covering tarpaulin 11 and the water delivery pipe 16 to retract in the opposite direction. By installing the component, the covering tarpaulin 11 can be rotated and wrapped for storage. At the same time, by connecting the component, the connecting hose 15 can be rotated and wrapped for storage. The entire device returns to its initial state and is ready for the next use.
