Description

Technical Field

[0001] This utility model relates to the field of tarpaulin track technology, and in particular to an adjustable arc-shaped tarpaulin track. Background Technology

[0002] In the freight transportation industry, to ensure that goods are protected from rain, sun, and dust during transport, truck bodies are generally equipped with retractable tarpaulin structures. To ensure smooth tarpaulin deployment, an arc-shaped track structure is typically installed on the top of the truck body to guide the tarpaulin's sliding movement. This type of structure is usually installed at the front and rear ends of the truck body and works in conjunction with the tarpaulin traction mechanism to complete the covering and uncovering operations; it is an indispensable and crucial component of automated tarpaulin systems.

[0003] In existing technologies, curved track structures are mostly fixed designs. The track is fixed to the top of the carriage or a column by welding or bolting, and its position and angle are difficult to adjust after installation. The tarpaulin slides along the track and is guided by sliders, hooks, or rollers located inside the track. Although the overall structure has a certain guiding and load-bearing capacity, it is often affected by factors such as vehicle deformation and changes in load after long-term operation, which leads to problems such as increased running resistance of the tarpaulin, track misalignment, or slider jamming, affecting its service life and sealing effect.

[0004] However, existing curved track devices generally lack adjustment functions. Especially when vehicles are used for a long time and the carriage structure is slightly deformed, the track is difficult to adjust its position according to the actual situation, which leads to obstruction of tarpaulin traction, poor device stability, and insufficient adaptability. It cannot meet the technical requirements of tarpaulin system adjustability and reliability in high-intensity transportation scenarios. Therefore, an adjustable curved track for tarpaulins is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable arc-shaped track with a tarpaulin, which aims to improve the problem that existing arc-shaped track devices generally lack adjustment functions, especially when the vehicle has been used for a long time and the carriage structure has undergone slight deformation, making it difficult to finely adjust the position of the track according to the actual situation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable arc-shaped track for tarpaulins, comprising a main rod, an arc-shaped track body fixedly connected to the upper surface of the main rod, a sliding component installed inside the arc-shaped track body, and an adjustment component installed on the lower surface of the main rod;

[0007] The adjustment assembly includes a housing, a nut, and a bolt. The upper surface of the housing is fixedly connected to the lower surface of the main rod. One side of the nut is fixedly connected to the outer wall of the housing. The inner wall of the nut is threadedly connected to the outer wall of the bolt. A connecting rod is slidably connected inside the housing.

[0008] Furthermore, the sliding assembly includes a slider and a suspension block, with one side of the outer wall of the suspension block fixedly connected to one side of the outer wall of the slider, and both the outer walls of the slider and the suspension block being slidably connected along the inner wall of the arc-shaped track body.

[0009] Furthermore, a plug rod is fixedly connected to one side of the lower surface of the connecting rod, and the plug rod is used to connect to the truck canopy support column.

[0010] Furthermore, a roller is rotatably connected to one side of the slider, and the outer side of the roller abuts against the inner wall of the arc-shaped track body to pull the tarpaulin along the track.

[0011] Furthermore, both ends of the main rod and the arc-shaped track body are fixedly connected to hemispherical shells, and the inner cavity of the hemispherical shells abuts against the ends of the main rod and the arc-shaped track body to protect the tarpaulin from scratches.

[0012] Furthermore, the outer wall of the bolt is disposed through the inside of the housing, and one end of the bolt abuts against one side of the outer wall of the connecting rod.

[0013] Furthermore, the main rod and the arc-shaped track body are connected and supported by multiple support pillars.

[0014] Furthermore, the hemispherical shell is higher than the connecting rod, and multiple sets of sliding components are provided for connecting the tarpaulin to move along the arc-shaped track body.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by setting an adjustment component, a sleeve, nut, and bolt structure are arranged below the main rod. Combined with connecting rods and insert rods, the track position can be finely adjusted according to the deformation of the freight car body, adapting to different car body sizes. This effectively improves the overall installation adaptability and usage flexibility, enhancing the versatility and stability of the device. The sliding component, through the sliding cooperation of the slider and suspension block within the arc-shaped track, can smoothly unfold or retract the tarpaulin along the track, ensuring stable operation and preventing jamming. Simultaneously, the roller structure reduces running friction resistance, minimizes component wear, and improves service life and operational efficiency.

[0017] 2. In this utility model, hemispherical shell structures are set at both ends of the main rod and the track, which can effectively prevent the edges of the tarpaulin from being scratched or torn during operation, thus enhancing the protective performance of the tarpaulin. The overall track structure is connected to the main rod through the support pillars to form a stable support, with high overall strength, suitable for various truck application scenarios. In addition, the sliding components adopt multiple combination configurations, which can improve the load-bearing capacity while balancing the force, adapting to the traction needs of large-area tarpaulins. The structure is simple, easy to install, and flexible to adjust, effectively reducing the incompatibility problems caused by the deformation of the carriage during long-term use of traditional fixed tracks, and improving the durability and reliability of the device.
