Description

Technical Field

[0001] The utility model relates to a tarpaulin covering device for a muck truck, belonging to the technical field of muck truck equipment. Background Technique

[0002] In recent years, with the development of urban construction and the comprehensive utilization of land, muck trucks shuttle on urban roads, causing great harm to the urban environment and people's lives. Therefore, existing muck trucks are all equipped with tarpaulin covering devices to block with tarpaulins to prevent muck from leaking and flying.

[0003] Existing automatic tarpaulin covering devices for muck trucks have the ways of covering the tarpaulin by wire dragging and covering the tarpaulin by the rotation of a steel frame. There are problems that the sealing around is not tight, and due to reasons such as wind force and bumpiness, there will still be situations of spilling and dusting. Moreover, these two covering methods have simple structures and insufficient restraint on the tarpaulin. When the vehicle is driving at a high speed, due to the large wind force and unstable wind direction, the tarpaulin will shift to the side of the vehicle or even fall off, seriously affecting the safety of itself and other vehicles and pedestrians, and the use effect is not ideal. If the soil pile in the muck truck carriage is relatively high, it is not convenient to cover, and the tarpaulin is exposed in the retracted state. Over time, it is easy to reduce the service life of the tarpaulin due to weather factors. Therefore, it is very necessary to improve the existing tarpaulin covering device for muck trucks.

The rotating shaft 5 drives the driving sprocket 7 to rotate. The driving sprocket 7 meshes with the chain 8 to drive the chain 8 to move. The chain 8 drives the outermost tarpaulin moving bracket 10 to move. During this process, the pulley 16 in the slider 9 slides in the chute of the slide rail 3. When the tarpaulin moving bracket 10 moves, it drives the tarpaulin 2 to move. With the movement of the tarpaulin 2, the slider 9 at the lower part of the subsequent tarpaulin moving bracket 10 is pulled to slide inside the slide rail 3. When the rotating bracket 11 moves to a position in contact with the baffle 21, with the movement of the chain 8, the rotating bracket 11 rotates until the tarpaulin support rod 12 on the rotating bracket 11 completes the flipping, so that the tarpaulin 2 on the tarpaulin support rod 12 is hermetically attached to the other end of the carriage 1, thus completing the covering of the tarpaulin body 2. When it is necessary to wind up the tarpaulin 2, the double-shaft extended asynchronous motor 4 is started, and the double-shaft extended asynchronous motor 4 is driven in the reverse direction until the tarpaulin 2 is stored in the storage seat 17.
