[0030] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] Please refer to the attached Figure 1-Figure 5The embodiments of the present application provide a tarpaulin mechanism suitable for installation on a vehicle, such as a dump truck or a van. The tarpaulin mechanism includes a tarpaulin 400, poles 300 disposed on both sides of the tarpaulin 400, guide rails, a pulley 100 connected to the poles 300 and moving along the guide rails, and a traction device for driving the pulley 100. The traction device specifically includes a power member and a traction rope, such as a chain or rope, connected to the pulley 100. Thus, the traction device drives each pulley 100 along the guide rails, allowing each pole 300 to unfold or retract with the tarpaulin 400. In the present application, the pulley 100 includes a frame 10 and rollers 17. The frame 10 includes a base plate 11, a connecting portion disposed on the base plate 11 for connecting to the poles 300, a support portion disposed on the base plate 11, and a fixing plate 14 connected to the support portion for fixing the rollers 17. As a result, the frame 10 of the pulley 100 is clearly structured and stable. At the same time, the frame 10 is an integrated structure, that is, the bottom plate 11, the connecting part, the supporting part and the fixing plate 14 are an integrated structure. These parts are formed as one piece and do not need to be connected by welding. Therefore, the frame 10 is not only structurally stable, but also has high overall structural strength and is not easy to deform, thereby enhancing the deformation resistance of the pulley 100 and improving the problem that the pulley 100 is easily deformed after long-term use, resulting in operation jamming, thereby affecting the normal unfolding or folding of the tarpaulin 400.

[0032] At the same time, the integral molding of the frame 10 also facilitates the lightweight design of the frame 10. In the field of vehicles, the lightweight design of the vehicle body has always been an important factor in terms of load and transportation performance. In this application, the structure of the pulley 100 is optimized and integrally molded, which not only enhances the deformation resistance of the frame 10, but also helps reduce the weight of the frame 10 compared to welding various components, thus meeting the requirements of lightweight design. For example, the material of the frame 10 is aluminum alloy, which not only facilitates the integral molding of the frame 10 and facilitates the processing of various parts such as the bottom plate 11, the support portion, and the fixing plate 14, but also is lightweight. At the same time, compared to welded parts, the integral molding or integrally structured aluminum alloy parts can also improve corrosion resistance.

[0033] like Figure 1 and Figure 2 As shown, the base plate 11 is exemplarily a plate structure, and the support portion includes a support plate 13 and support legs 12 spaced apart along a first direction. The support legs 12 include at least two support legs spaced apart along a second direction. The support plates 13 and support legs 12 are located at both ends of the fixed plate 14. This allows for the spacing between the support plates 13 and support legs 12, as well as the spacing between the two support legs, to facilitate the installation of the roller 17 onto the fixed plate 14. Furthermore, the structural combination of the support plates 13 and support legs securely connects the fixed plate 14 and the base plate 11, enhancing the overall structural stability and strength of the integrated vehicle frame 10.

[0034] In a further embodiment, the support leg includes a first section connected to the bottom plate 11 and a second section connecting the first section and the fixing plate 14, and the support leg is L-shaped or L-like as a whole, such as Figure 1 As shown, the supporting legs not only have a longer section that is closely connected to the base plate 11 , but also firmly support the fixing plate 14 with high strength.

[0035] In some embodiments, the fixing plate 14 includes a main board and a wing plate 141 arranged between the supporting legs. The wing plate 141 is connected to both the main board and the supporting legs. In addition, the fixing plate 14 and the supporting legs are an integrated structure. It can be seen that this structural setting has a stable structure, high strength, and strong anti-deformation ability.

[0036] In some embodiments, the support portion further includes a reinforcing rib 15 . The reinforcing rib 15 is located on a side of the support plate 13 away from the support legs and is connected to the support plate 13 and the fixing plate 14 .

[0037] like Figure 1 As shown, for example, the connection portion includes two vertical plates 16 erected on the bottom plate 11 and spaced apart, and the two vertical plates 16 are each provided with a first connection hole 161 arranged opposite to each other. The two vertical plates 16 are spaced apart and arranged opposite to each other, and the spacing between the two vertical plates 16 forms a plug-in space for the shed pole 300 to be inserted. After the shed pole 300 is inserted, the two vertical plates 16 are connected to the shed pole 300 on both sides of the shed pole 300. For example, through the setting of the first connection hole 161, the bolts pass through the vertical plates 16, the shed pole 300 and the vertical plates 16 in sequence, thereby realizing a stable connection between the pulley 100 and the shed pole 300. In this way, the pulley 100 can be firmly connected to the shed pole 300, and the shed pole 300 can be limited in the horizontal direction to prevent the shed pole 300 from shaking left and right or misaligning.

[0038] Specifically, in some embodiments, in the length direction, the vertical plate 16 includes a recessed portion and raised portions located at both ends of the recessed portion, and the first connection hole 161 is provided on the raised portion.

[0039] The areas on both sides of the connecting portion of the bottom plate 11 are also provided with second connecting holes 111 for connecting to the shed rod 300. In this way, when the portion of the shed rod 300 for connecting to the bottom plate 11 is a flat plate structure, it can also be directly connected to the bottom plate 11.

[0040] The roller 17 includes a single roller and a double roller for respectively clamping on the upper and lower sides of the guide rail. The double roller consists of two rollers 17. A pressure plate 18 is provided on the side of the double roller away from the fixed plate 14. Bolts pass through the pressure plate 18 and the roller 17 to connect with the fixed plate 14, thereby fixing the double roller on the fixed plate 14, while the single roller can be fixed on the fixed plate 14 by bolts and washers.

[0041] The cross section of the guide rail is I-shaped or circular. The surface of the roller 17 has a groove for the guide rail to be embedded in. The cross section of the groove can be trapezoidal or arc-shaped accordingly.

[0042] The roller 17 can be a nylon wheel; this is also conducive to lightweight configuration.

[0043] The tarpaulin mechanism also includes a cornering device 200 for changing the direction of the traction cable. The cornering device 200 comprises a bracket 20, a cornering wheel 21 mounted on the bracket 20, and a protective baffle 22 positioned radially to one side of the cornering wheel 21 to partially cover the wheel surface. The cornering wheel 21 is provided with a positioning groove for the traction cable to fit into and prevent misalignment. The protective baffle 22 prevents the traction cable from falling off in the corner area.

[0044] In a further embodiment, Figure 5 As shown, the protective baffle 22 includes an arc segment, which includes an arc plate set in the corner area for the traction rope to change direction; the arc plate matches the angle of the corner wheel 21, which can increase the angle area and enhance protection.

[0045] In some embodiments, the protective baffle 22 has a U-shaped cross-section, comprising a baffle and side panels arranged on either side of the baffle. The baffle comprises a curved panel and a straight panel connected to the curved panel. This provides a protective covering for the corner area and the rope-traveling area behind the corner, increasing the protective corner area and the protective structure. This effectively prevents mud and sand from entering the cornering wheel 21 and causing blockage, and also prevents other components from contacting and interfering with the traction rope.

[0046] In some embodiments, the turning device 200 further includes a guide wheel 23, which is located in front of the turning wheel 21, that is, the traction rope first passes through the guide wheel 23, is guided by the guide wheel 23 and ensures the direction is accurate, and then passes through the turning wheel 21 to change direction.
