Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of covering environmental protection devices for vehicle, which is a device mainly used for covering materials in vehicle cargo compartment, belonging to vehicle technical field. BACKGROUND

[0002] When transporting materials such as sand and soil, engineering vehicles generate a large amount of dust, which affects the environment.

[0003] To avoid dust pollution, existing engineering vehicles mostly use dust-proof tarpaulins to cover the upper part of the vehicle compartment and fix the tarpaulins with ropes when transporting materials such as sand and soil. Although this dust-proof method can achieve a certain dust-proof effect, the installation and removal of the tarpaulin need to be operated manually, which is troublesome, time-consuming and labor-intensive.

[0004] There are also automatic tarpaulin covering mechanisms for covering vehicle compartments in the prior art. For example, Chinese patent document CN114312547A discloses a truck automatic tarpaulin covering device, which includes a housing, a drive device, a transmission assembly, a leveling mechanism, a lifting assembly, and a pulling assembly. The drive device includes a motor, a shaft, a roller, and a tarpaulin. The motor drives the roller to rotate to wind and unwind the tarpaulin. The transmission assembly includes a worm gear, a threaded rod, and a moving frame. The threaded rods are arranged on both sides of the housing. The side wall of the moving frame is slidably connected to the inner side wall of the housing. The two ends of the moving frame are connected to the two threaded rods. When the threaded rods rotate, they can drive the moving frame to move, thereby covering the tarpaulin on the top of the vehicle compartment. During the movement of the moving frame, the leveling mechanism levels the materials accumulated on the top of the truck, and the lifting assembly lifts the tarpaulin to prevent rainwater from accumulating on the top of the tarpaulin and affecting the materials inside the truck. This automatic tarpaulin covering structure not only has a complex structure and high cost, but also is limited by the height of the moving frame. The height of the material accumulation in the vehicle compartment is limited, otherwise it will limit the normal movement of the moving frame. Therefore, it must be equipped with a leveling mechanism to ensure the normal operation of the automatic tarpaulin covering mechanism. There is a significant limitation in its use. SUMMARY

[0005] In view of the above-mentioned defects in the prior art, the utility model provides a vehicle covering environmental protection device with simple structure, low cost and strong adaptability.

[0006] The utility model discloses a vehicle covering environmental protection device, characterized by comprising tarpaulin winding mechanism A set in the front end of the cargo compartment and tarpaulin winding mechanism B set in the rear end of the cargo compartment, tarpaulin winding mechanism A sets on the upper portion of the compartment body board of the front end of the cargo compartment, tarpaulin winding mechanism A includes first rotary shaft, and one end of first rotary shaft is connected with the output shaft of the driving device that drives it to rotate through sleeve, and the other end of first rotary shaft is connected with first bearing assembly, and tarpaulin winding mechanism B sets on the lifting mechanism, and tarpaulin winding mechanism B includes second rotary shaft, and one end of second rotary shaft is connected with the output shaft of the driving device that drives it to rotate through sleeve, and the other end of second rotary shaft is connected with second bearing assembly, and the second bearing assembly end of second rotary shaft and the driving device end of second rotary shaft are connected with a support rod respectively, and the lifting mechanism includes two lifting oil cylinders, and the two lifting oil cylinders are arranged in the two cargo compartment square tubes of the rear part of the cargo compartment respectively, and the two ends of second rotary shaft are connected with the telescopic ends of the two lifting oil cylinders through the two support rods respectively, and one end of tarpaulin is wound on first rotary shaft, and the other end of tarpaulin is connected with a tarpaulin traction rope on both sides respectively, and the two tarpaulin traction ropes are wound at the traction rope groove at the two ends of second rotary shaft, and a plurality of lead sinkers are fixed at the length direction interval of the two side edges of tarpaulin.

The two tarpaulin traction ropes are wound at the two traction rope grooves of the second rotary shaft at the end of tarpaulin, and one function is that when the second rotary shaft rotates to make tarpaulin cover the top of the cargo compartment, the traction rope is first wound in the traction rope groove and does not protrude from the surface of the rotary shaft, so that the winding of tarpaulin on the second rotary shaft is smooth, and the collection and release of tarpaulin by tarpaulin winding mechanism B are smooth, and the second function is that when tarpaulin is completely collected, the two tarpaulin traction ropes do not block the cargo compartment and do not affect the loading and unloading of materials.
