Description

Technical Field

[0001] The utility model relates to the technical field of truck tarpaulin laying, in particular to a tarpaulin laying structure for general cargo transport vehicles. Background Art

[0002] Existing truck tarpaulins are all automatically laid and stored using automated devices, which greatly improves efficiency and also improves safety because there is no need for manual climbing on the truck. However, in actual use, it is found that this automated device still has some defects.

[0003] For example, an electric device for folding and storing tarpaulins on a warehouse truck with application number CN202220643678.1 is used for automatically laying and storing tarpaulins on the top of the truck. The device includes a front bracket and a rear bracket arranged on both sides of the width of the truck top, as well as a groove wheel arranged on the front bracket, a driven pulley arranged on the rear bracket, and a steel wire rope wound around the groove wheel and the driven pulley. One side of the tarpaulin is fixed to the front bracket, and the other side is fixed to the steel wire rope. The steel wire rope is driven by driving the groove wheel to rotate, thereby realizing automatic laying and storage of the tarpaulin on the top of the truck, replacing traditional manual operation and improving work efficiency.

[0004] The defect of the above device is that, in order to facilitate the loading of cargo by crane, a fixed seat is provided on the rear bracket, and an L-shaped slide groove is provided on the fixed seat. One end of the bayonet is slidably matched with the fixed seat through the slide groove, and the driven pulley is rotated on the other end of the bayonet (such as Figure 1 As shown in the figure, when removing the wire rope before overhead crane loading, it is necessary to manually push the bayonet to rotate at least 90 degrees, and then remove the bayonet from the fixed seat for overhead crane loading. Although this makes it very convenient to remove the bayonet from the fixed seat, since the wire rope is usually in a taut state, the bayonet requires a lot of force to complete the removal and subsequent assembly process, which undoubtedly increases the difficulty of operation and reduces work efficiency. Utility Model Content

When in use, the wire rope can be loosened or tightened by adjusting the gap between the fixed block and the movable block, so that the pin can be easily rotated to remove it from the fixed seat, and the wire rope can be easily and conveniently locked, thereby reducing the difficulty of operation and greatly improving efficiency.

[0009] Furthermore, the movable block and the fixed block are connected by a laterally arranged adjusting rod, and the lateral spacing is adjusted by the adjusting rod. Specifically, the adjusting rod is located on the lower side of the driven pulley, the middle part of which is rotatably connected to the movable block, the two ends extend out on both sides of the movable block, and the end close to the fixed block is threadedly connected to the fixed block. When in use, the spacing between the movable block and the fixed block can be adjusted by rotating the adjusting rod, so that the pin can be easily rotated, and the wire rope can be easily loosened or tightened. The structure is simple and easy to process.

[0010] For ease of use, a boss abutting against one side of the movable block is further provided on the side of the adjusting rod facing away from the fixed block.

[0011] Furthermore, the driven pulley is arranged on the rear side of the fixed seat to prevent the driven pulley part from extending into the inside of the truck and obstructing the overhead crane loading.
