[0041] This utility model proposes a rainproof cloth covering device 100.

[0042] Please see Figures 1 to 3 In one embodiment of this utility model, the rainproof tarpaulin covering device 100 includes a crossbeam 1, a walking device 2, and a traction device 3. Specifically, the rainproof tarpaulin covering device 100 is generally used to cover the rainproof tarpaulin 200 of trucks (objects to be covered). The crossbeam 1 is usually set above the truck parking area such as warehouses and freight yards, and is fixed to the steel beams of walls, frames, canopies, etc. by bolt connection, welding, etc. The crossbeam 1 extends along a first direction. The walking device 2 is movably set on the crossbeam 1. The traction device 3 is set and connected to the walking device 2. The walking device 2 is used to drive the traction device 3 to move along the first direction on the crossbeam 1. The traction device 3 includes a lifting mechanism 31 and at least two hooks 32 driven and connected to the lifting mechanism 31. The at least two hooks 32 are spaced apart along a second direction. The lifting mechanism 31 is used to drive the hooks 32 to rise and fall along a third direction.

[0043] In this embodiment, the first direction is the length direction of the truck, the second direction is the width direction of the truck, and the third direction is the height direction of the truck. When performing the tarpaulin 200 covering operation, the lifting mechanism 31 can be controlled to lower the hook 32 to a certain height along the third direction. The short side of the tarpaulin 200 is then manually attached to the hook 32. The lifting mechanism 31 is then controlled to raise the hook 32 to a preset height. Finally, the traveling device 2 is controlled to move the lifting mechanism 31 and the hook 32 along the first direction to drag the tarpaulin 200 and cover the top of the truck. It can be understood that once the tarpaulin 200 is attached to the hook 32, the tarpaulin covering device 100 can automatically perform lifting and traction operations, eliminating the need for manual work on the truck at height, significantly improving operational safety and processing efficiency.

[0044] It should be noted that the traveling device 2 can be a guide rail electric trolley, or a device driven by a motor or other drive mechanism, and equipped with gears, racks, sprockets, guide rails, pulleys, etc., to achieve the function of movement, as long as it can drive the traction device 3 to move back and forth on the crossbeam 1 in the first direction; furthermore, the lifting mechanism 31 can be configured as an electric crane 311, which includes one or more of the following: electric hoist, winch, rack and pinion jack, screw jack, hydraulic jack, winch, electric hoisting device, etc. The corresponding connecting part 32 can be configured as a hook, hanging ring, heavy-duty clamp, etc. The connecting part 32 can be connected to the lifting mechanism 31 through wire rope, chain, etc., so as to drive the connecting part 32 to rise and fall in a third direction. The specific structure of the traveling device 2 and the traction device 3 is not specifically limited here, and can be selected according to actual needs.

[0045] Please refer to Figure 6 In another embodiment of this utility model, the first direction is set as the width direction of the truck, the second direction is set as the length direction of the truck, and the third direction is set as the height direction of the truck. The crossbeam 1 extends along the width direction of the truck, and at least two hooks 32 are spaced apart along the length direction of the truck. This structure is used to pull the tarpaulin 200 from the side of the truck, and can cover trucks in multiple parking spaces at once.

[0046] It should be noted that the first direction, the second direction, and the third direction intersect each other. The first direction can be set along either the length or the width of the object to be covered, and the second direction can be set along the other one. Of course, the first and second directions can also be set along other directions, as long as the tarpaulin can cover 200 trucks. There are no specific limitations here. The settings can be made according to the number of trucks (objects to be covered), the area to be covered, the covering method, etc.

[0047] In one embodiment of this utility model, the walking device 2 further includes a moving mechanism 21. Specifically, the moving mechanism 21 can be a component with a moving function, such as a guide rail electric trolley, and can be movably mounted on the crossbeam 1, such as... Figure 7 and Figure 8 As shown, the lifting mechanism 31 is directly connected to the moving mechanism 21. When the moving mechanism 21 moves along the first direction on the crossbeam 1, it can drive the lifting mechanism 31 and the hook 32 connected to the lifting mechanism 31 to move synchronously. If the rainproof cloth covering device 100 is equipped with multiple crossbeams 1, the walking device 2 and the traction device 3 on each crossbeam 1 do not interfere with each other, making the dragging of the rainproof cloth 200 more flexible.

[0048] Or, such as Figure 2 and Figure 3 As shown, in another embodiment of this utility model, the lifting mechanism 31 is indirectly connected to the moving mechanism 21 through an intermediate component. This intermediate component can be a connecting seat, a movable beam, etc. By adjusting the position of the lifting mechanism 31 on the intermediate component, the positional distribution of the lifting mechanism 31 and the hanging part 32 in the second direction can be controlled, so that the hanging position of the hanging part 32 and the rainproof cloth 200 is more reasonable, which is conducive to improving operating efficiency. As for whether the lifting mechanism 31 and the moving mechanism 21 are directly or indirectly connected, it can be selected according to actual needs, and no specific limitation is made here.

[0049] like Figures 2 to 4 As shown, in one embodiment of this utility model, the walking device 2 further includes a movable beam 22. Specifically, both the crossbeam 1 and the movable beam 22 adopt an I-beam structure. The movable beam 22 is connected to the moving mechanism 21 by bolts. The lifting mechanism 31 is located on the movable beam 22. The moving mechanism 21 moves along the first direction on the crossbeam 1, which can drive the movable beam 22 and the lifting mechanism 31 to move along the first direction and cause the hanging part 32 to pull the rainproof cloth 200.

[0050] I-beams possess excellent structural strength. By connecting the lifting mechanism 31 and the moving mechanism 21 with the movable beam 22, they provide stable support for the traction device 3 and position the mounting bracket 32 ​​appropriately for lifting. Of course, the crossbeam 1 and the movable beam 22 can also be made of steel of other shapes, as long as they possess the required structural strength. Furthermore, the lifting mechanism 31 can be positioned at different locations on the movable beam 22 to accommodate trucks of different sizes and rainproof cloths 200, making it suitable for various types of operations and greatly improving the equipment's adaptability.

[0051] like Figure 3 and Figure 4As shown, in one embodiment of this utility model, the movable beam 22 extends along a second direction, and the lifting mechanism 31 includes at least two electric cranes 311. The number of hooks 32 is the same as the number of electric cranes 311 and they are connected one-to-one. The at least two electric cranes 311 are arranged at intervals along the second direction on the movable beam 22, so that the at least two hooks 32 are arranged at intervals along the second direction for hanging at least two points on the side of the rainproof cloth 200. It can be understood that each hook 32 corresponds to one electric crane 311, which can evenly distribute the load and avoid the electric cranes 311 from being overloaded or even damaged due to the excessive weight of the rainproof cloth 200, thus helping to improve the operational stability of the system.

[0052] Of course, in some other embodiments of this utility model, if the power of the electric crane 311 is high enough or the weight of the rainproof cloth 200 is small, a single electric crane 311 can be connected to at least two hangers 32, or the number of electric cranes 311 can be less than the number of hangers 32, and there is no specific limitation.

[0053] like Figure 2 and Figure 6 As shown, in one embodiment of this utility model, the rainproof tarpaulin covering device 100 includes at least two crossbeams 1 spaced apart along a second direction. Each crossbeam 1 is equipped with a moving mechanism 21. A movable beam 22 extends along the second direction and is connected to the moving mechanism 21 on each crossbeam 1. The moving mechanism 21 on each crossbeam 1 moves synchronously, so that the movable beam 22 moves along a first direction. It can be understood that by providing at least two crossbeams 1, the weight of the movable beam 22 and the traction device 3 on the movable beam 22 can be evenly distributed, avoiding deformation or breakage of the crossbeams 1 and improving the safety of the rainproof tarpaulin covering device 100.

[0054] Furthermore, such as Figure 2 In the embodiment shown, the rainproof cloth 200 is covered by pulling along the length of the truck. The pulling device 3 only needs to be equipped with two lifting mechanisms 31 and a hook 32 on the short side of the rainproof cloth 200, and two crossbeams 1 are spaced apart along the second direction. This pulling method is suitable for operation of a single truck.

[0055] like Figure 6In the illustrated embodiment, when dealing with multiple trucks, the rainproof cloth 200 is pulled along the width of the truck for covering, which is more efficient than pulling along the length of the truck. In this embodiment, the traction device 3 is equipped with four lifting mechanisms 31 and four hooks 32 on the long side of the rainproof cloth 200. The movable beam 22 extends along the second direction. To ensure the stable operation of the traction device 3, four crossbeams 1 are spaced apart along the second direction to support the movable beam 22 and the traction device 3. The longer the crossbeam 1 is, the more parking spaces the rainproof cloth covering device 100 can cover, which helps to reduce costs.

[0056] Of course, in some other embodiments of this utility model, the number of crossbeams 1 can be three, five, six, etc., and there is no specific limitation. It can be adapted to factors such as the traction method of the rainproof cloth 200, the length of the truck, the number of parking spaces, and the load-bearing weight.

[0057] like Figure 7 and Figure 8 As shown, in one embodiment of this utility model, the rainproof tarpaulin covering device 100 includes at least two crossbeams 1 spaced apart along a second direction. Each crossbeam 1 is equipped with a moving mechanism 21, and the lifting mechanism 31 includes at least two electric cranes 311. Each moving mechanism 21 is connected to an electric crane 311, and each electric crane 311 is drivenly connected to a hook 32. When it is necessary to pull the rainproof tarpaulin 200, the corresponding electric crane 311 can be controlled to drive the hook 32 connected to it to lift and lower, thus performing the covering operation of the rainproof tarpaulin 200. It can be understood that each moving mechanism 21 is connected to an electric crane 311, so that the traveling device 2 and the traction device 3 on each crossbeam 1 do not interfere with each other, and the corresponding moving mechanism 21 and electric crane 311 can be activated as needed, making the operation more flexible.

[0058] like Figure 4 and Figure 5 As shown, in one embodiment of this utility model, the moving mechanism 21 includes a mounting base 211 and a first power component 212 and a transmission component 213 disposed on the mounting base 211. Specifically, the transmission component 213 is movably disposed on the crossbeam 1 and drivenly connected to the first power component 212. When the first power component 212 drives the transmission component 213 to move, it can drive the moving mechanism 21 to move back and forth on the crossbeam 1 along a first direction. It should be noted that the first power component 212 can be a motor or other driving mechanism, and the transmission component 213 can be configured as a roller 2131, gear, chain, or other components. The crossbeam 1 is provided with a transmission structure that cooperates with the transmission component 213 to realize the moving function of the moving mechanism 21. No specific limitations are made here.

[0059] like Figure 4 and Figure 5As shown, in one embodiment of this utility model, the crossbeam 1 is provided with a track 1a on each of its opposite sides along the second direction. The track 1a extends along the first direction. The mounting base 211 of the moving mechanism 21 is provided with a clearance groove. Rollers 2131 are provided on the two opposite side walls of the clearance groove in the second direction. The axis of the rollers 2131 is arranged along the second direction and is driven and connected to the first power member 212. The crossbeam 1 passes through the clearance groove so that the rollers 2131 abut against the side walls of the track 1a. When the first power member 212 drives the rollers 2131 to rotate, the moving mechanism 21 can be driven to move along the track 1a on the crossbeam 1.

[0060] like Figure 4 As shown, in one embodiment of this utility model, the lifting mechanism 31 includes at least one electric crane 311 and at least two slings 312. Specifically, the electric crane 311 includes a second power component 3111 and a winding assembly 3112 driven and connected to the second power component 3111. The number of slings 312 is the same as the number of hooks 32. One end of each sling 312 is connected to a hook 32, and the other end is connected to the winding assembly 3112. When the second power component 3111 drives the winding assembly 3112 to rotate, the winding assembly 3112 winds or releases the sling 312, so that the hook 32 rises or falls in a third direction. It should be noted that the slings 312 adopt connecting parts with winding and coiling properties, such as chains, wire ropes, nylon ropes, etc., and are not specifically limited, and can be selected according to actual needs.

[0061] like Figure 1 As shown, in one embodiment of this utility model, the rainproof cloth covering device 100 also includes a canopy 4, which can be installed on the outer wall of a freight yard or warehouse or on a support column 5. A crossbeam 1 is located below the canopy 4. The crossbeam 1 can be fixed to the wall by expansion screws, or connected to the support column 5 or the steel beam below the canopy 4 by bolts or welding. The installation method depends on the location of the canopy 4.

[0062] like Figure 7 As shown, in another embodiment of this utility model, the parking area of ​​the truck is located in an open-air scene, and the rainproof cloth covering device 100 also includes a frame 6. The frame 6 is made of steel, the canopy 4 is located at the upper end of the frame 6, and the crossbeam 1 can be connected to the frame 6 by bolts or welding.

[0063] In one embodiment of this utility model, the rainproof cloth 200 has a hooking part that cooperates with the hooking member 32. One of the hooking member 32 and the hooking part is configured as a hook, and the other is configured as a hanging ring. Of course, the hooking member 32 and the hooking part can also be configured as hanging lugs, straps, or other components, as long as the rainproof cloth 200 can be hung on the hooking member 32, and there is no specific limitation.

[0064] In one embodiment of this utility model, a limiting device is also provided at the end of the crossbeam 1. This limiting device is used to abut against the limiting travel device 2 to prevent the travel device 2 from moving beyond a preset stroke. Specifically, the limiting device may be a stop block provided in the track 1a. The stop block is provided at the end of the crossbeam 1 to abut against the roller 2131 of the moving mechanism 21; or, structures such as limiting pins, gaskets, and limiting posts may also be provided to abut against the travel device 2.

[0065] In one embodiment of this utility model, the rainproof cloth covering device 100 also includes a control system. The walking device 2 and the traction device 3 are provided with interfaces connected to the control system, which can receive remote control commands so that the control system can accurately control the moving direction, speed, distance, etc. of the walking device 2 to achieve accurate coverage of the rainproof cloth 200.

[0066] Furthermore, the tarpaulin covering device 100 is also equipped with an overload protection device. When the load on the traction device 3 exceeds a preset value, the overload protection device cuts off the power supply to prevent the traction device 3 from being damaged due to overload operation. This overload protection device can be a circuit breaker installed in the power supply and traction device 3 circuit. When an overload is detected in the traction device 3, the circuit breaker triggers a disconnect operation to achieve protection. In addition to circuit breakers, the overload protection device can also be a thermal magnetic switch, relay, or other devices, and there is no specific limitation.

[0067] In one embodiment of this utility model, the tarpaulin covering device 100 further includes a fall prevention device. This fall prevention device is located on the traction device 3. When the sling 312 breaks inside the electric crane 311, the fall prevention device locks the sling 312 to prevent the hook-and-loop fastener 32, the tarpaulin 200, and the broken sling 312 from falling and injuring people. This fall prevention device can be equipped with mechanical components such as springs, clutches, or sliders to quickly lock the sling 312 or other connecting devices, thereby preventing falls.

[0068] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
