Description

Technical Field

[0001] This utility model relates to the field of vehicle tarpaulin covering technology, and in particular to a road transport tarpaulin covering operation platform. Background Technology

[0002] As an important supplement to rail and water transport, road transport is characterized by its high flexibility, small footprint, adaptability to terrain conditions, low cost, and diverse types of transport equipment. However, due to environmental protection requirements or the nature of the goods themselves, road transport vehicles usually need to be covered with tarpaulins after being fully loaded. In the current technology, a considerable proportion of tarpaulin installations are done manually by climbing up and down, which is not only inefficient but also poses significant safety hazards.

[0003] Based on this, many automated tarpaulin covering platforms have emerged. For example, utility model patent CN 218431035 U discloses an automated vehicle tarpaulin covering device, which includes a device body. The device body includes multiple columns fixedly installed on the ground and arranged in a square shape, a drive mechanism installed on the top of the columns, and a moving mechanism arranged inside the columns and cooperating with the drive mechanism. The drive mechanism includes a transmission shaft arranged on the top of multiple columns on the same side and connected through it, a coupling installed on both sides of the transmission shaft of each column on the same side, and a reducer arranged between the coupling on one side and the column. The reducer has a drive motor with a brake installed at its lower end, and a control switch is provided on the outermost column. The moving mechanism includes a guide rail arranged inside the columns, a sliding component installed on the guide rail, and two tarpaulin hangers connected to the sliding component and arranged in parallel.

[0004] This patented solution largely solves the problem of tarpaulin covering; however, during operation, when the tarpaulin needs to be laid first on the hanging poles on both sides, multiple workers are still required to spread the tarpaulin from one end of the hanging pole to the other, which is time-consuming and labor-intensive. Therefore, there is an urgent need for a road transport tarpaulin covering operation platform that can assist in spreading the tarpaulin on the hanging poles. Utility Model Content

[0005] The purpose of this utility model is to provide a road transport tarpaulin covering operation platform, which can assist in the unfolding and spreading of tarpaulins on the hanging poles on both sides, improve the convenience of tarpaulin laying, and increase work efficiency.

[0006] The present invention adopts the following technical solution:

[0007] A tarpaulin covering operation platform for highway transportation includes two symmetrically arranged columns. Adjacent columns in each column are connected by connecting beams, as are adjacent columns between columns. Each column has a hanging rod controlled by a drive mechanism for lifting. Each hanging rod has two pulleys at both ends, one of which is connected to a motor. A closed annular rope is fitted between the two pulleys. An adjustment groove is formed along the length of the hanging rod's side wall. The rope is connected to a movable seat located outside the hanging rod via the adjustment groove. The movable seat has clamping components for holding the tarpaulin.

[0008] Preferably, the hanging rod has an overall cylindrical structure.

[0009] Preferably, the movable seat is a semi-ring structure, and the movable seat is coaxially sleeved on the upper part of the hanging rod.

[0010] Preferably, a ball bearing is movably provided at the end of the movable seat away from the rope, and a guide groove is provided on the side wall of the hanging rod for the ball bearing to slide.

[0011] Preferably, the clamping member includes a support plate disposed on the movable seat, and a clamping plate is elastically disposed on the support plate, wherein the clamping plate is tightly fitted to the support plate in the initial state.

[0012] Preferably, the support plates are located on the front and rear sides of the movable seat along its moving direction, and the clamping plate is not less than the length of two support plates.

[0013] Preferably, the movable seat is provided with a support rod, a sleeve is provided in the middle of the clamping plate, the sleeve is sleeved on the outside of the support rod, and a spring is provided between the support rod and the sleeve.

[0014] Preferably, the clamping plate and the support plate are provided with intermeshing positioning teeth and positioning grooves.

[0015] Preferably, a rubber pad layer is provided outside the positioning tooth and inside the positioning tooth groove.

[0016] Preferably, both ends of the hanging rod are provided with inspection plates.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model has a motor-driven pulley installed inside the hanging rod, and a rope is sleeved on the pulley. The rotation of the pulley can drive the rope to move, thereby driving the moving seat to move along the length of the hanging rod. This allows the tarpaulin connected to the clamp to be unfolded and spread along the length of the hanging rod, improving the convenience of work, reducing labor intensity, and improving work efficiency.

[0023] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0024] like Figure 1 As shown, the road transport tarpaulin covering operation platform of this utility model includes two rows of symmetrically arranged columns 1. The two adjacent columns 1 in each row and the two adjacent columns 1 between the two rows are connected by connecting beams 2. Each column 1 is provided with a drive mechanism 3, which is used to control the lifting and lowering of the hanging rod 4. Since the above contents are all conventional settings disclosed in the prior art and are not the contents to be improved in this application, the specific working principle can be referred to the contents disclosed in the patent with publication number CN218431035U, and will not be described in detail here.

[0025] like Figures 2 to 5 As shown, in this embodiment, each hanging rod 4 has two pulleys 5 movably installed at both ends inside. One of the pulleys 5 is connected to a motor 6 via a right-angle reducer. A closed annular rope 7 is fitted onto the groove between the two pulleys 5. An adjustment groove 8 is provided on the side wall of the hanging rod 4 along its length. A connecting rod 9 is provided on the rope 7. The connecting rod 9 passes through the adjustment groove 8 and connects to a movable seat 10 located outside the hanging rod 4. The movable seat 10 is provided with clamping components for clamping the tarpaulin. The length of the adjustment groove 8 and the rope 7 is usually greater than the length of the tarpaulin. During operation, the two sides of one end of the tarpaulin are clamped onto the clamping components on the two hanging rods 4. Then, the two motors 6 are started simultaneously to drive the pulleys 5 to rotate. The rope 7 will drive the movable seat 10 to move from one end of the hanging rod 4 to the other end along the length of the adjustment groove 8 via the connecting rod 9. This completes the spreading of the tarpaulin on the hanging rod 4. The operation is simple and quick. Compared with the prior art that relies entirely on manual pulling, it greatly reduces labor intensity and improves work efficiency.

[0026] In this embodiment, the hanging rod 4 is preferably designed as a cylindrical structure, so that both ends of the hanging rod 4 are rounded, avoiding the presence of sharp edges and preventing wear and tear during the movement of the tarpaulin. Both ends of the hanging rod 4 are detachably equipped with inspection plates for easy inspection and maintenance of the internal pulleys 5 and ropes 7. Furthermore, the movable seat 10 is a semi-ring structure and is coaxially sleeved on the upper part of the hanging rod 4. The bottom of the hanging rod 4 is provided with spaced supports 11 for connecting a guide mechanism, which is slidably connected to a guide rail on the column 1. Multiple arc-shaped retaining rings 12 are also spaced at the bottom of the hanging rod 4 between the supports 11, so that after the tarpaulin is spread out, the retaining rings 12 can be used to secure the tarpaulin above the hanging rod 4, achieving a tight connection between the tarpaulin and the hanging rod 4 and preventing the tarpaulin from falling off when the hanging rod 4 is raised. In addition, a ball bearing 13 is movably provided at the end of the movable seat 10 away from the rope 7, and a guide groove 21 is provided on the side wall of the hanging rod 4 for the ball bearing 13 to slide. The sliding of the ball bearing 13 in the guide groove 21 can provide guidance support for the movable seat 10 and improve the stability of the movable seat 10 movement.

[0027] Furthermore, the clamping component includes a support plate 14 disposed on the movable base 10, and a clamping plate 15 elastically disposed on the support plate 14. In the initial state, the clamping plate 15 is tightly fitted with the support plate 14. A space for accommodating the tarpaulin is formed between the clamping plate 15 and the support plate 14. In use, the upper clamping plate 15 is pulled up to disengage it from the support plate 14, and then the tarpaulin is placed inside. Preferably, the support plate 14 is located on the front and rear sides of the movable base 10 along its moving direction, and the clamping plate 15 is not less than the length of two support plates 14; this arrangement ensures that the tarpaulin can be spread out when placed at different ends of the hanging rod 4.

[0028] Specifically, the clamping component includes a support rod 16, which is mounted on the movable seat 10. A sleeve 17 is provided in the middle of the clamping plate 15, which is sleeved on the outside of the support rod 16. A spring 18 is provided between the support rod 16 and the sleeve 17. The top of the spring 18 is connected to the fixed plate on the support rod 16. In the initial state, the spring 18 is in a natural state. When it is necessary to clamp the tarpaulin, the sleeve 17 is moved upward, the spring 18 is compressed, the clamping plate 15 is separated from the support plate 14, and the tarpaulin is placed in the space between the clamping plate 15 and the support plate 14. The clamping plate 15 is released and reset under the restoring force of the spring 18. In addition, a positioning tooth 19 and a positioning groove 20 that mesh with each other are provided between the clamping plate 15 and the support plate 14. The positioning tooth 19 and the positioning groove 20 are preferably arranged in an orientation perpendicular to the direction of movement of the tarpaulin, and multiple such arrangements are spaced apart along the direction of movement of the tarpaulin. This arrangement can increase friction and reduce the probability of the tarpaulin falling off between the clamping plate 15 and the support plate 14 when the tarpaulin moves. Rubber pads are provided on the outside of the positioning tooth 19 and inside the positioning groove 20 to reduce wear on the tarpaulin.

[0029] In operation, this invention first controls the hanging rod 4 to descend, clamping one end of the tarpaulin between the clamping plate 15 and the support plate 14 on the two hanging rods 4. Then, the motor 6 is turned on to move the tarpaulin to the other end of the hanging rod 4. After the tarpaulin is fully unfolded, the motor 6 is turned off. The tarpaulin is tightly connected to the hanging rod 4 by using the locking ring 12. Finally, the drive mechanism 3 is controlled to move the hanging rod 4 upward. When the tarpaulin is raised to a height higher than the vehicle, the vehicle travels to the platform formed by the two pillars 1. The drive mechanism 3 is then controlled to reverse and move the hanging rod 4 downward. The middle part of the tarpaulin will cover the cargo behind the vehicle, while the two sides will be located on both sides of the cargo compartment as the hanging rod 4 continues to descend. Finally, the locking ring 12 is removed to release the connection between the tarpaulin and the hanging rod 4, and the tarpaulin is then reinforced to the cargo compartment.
