Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a simple dump truck tarpaulin device. Background Technology

[0002] Dump trucks play a vital role in engineering construction, their unique structure and functions making them indispensable transportation equipment in modern construction. In fields such as earthwork engineering, mining, road construction, and water conservancy projects, dump trucks, with their automatic unloading hydraulic systems, can quickly complete the loading and unloading of bulk materials such as sand, gravel, earth, and concrete aggregates. For example, in large-scale infrastructure projects, a single 30-ton dump truck can complete dozens of round trips daily, increasing efficiency by more than five times compared to traditional manual unloading. Its U-shaped cargo box and reinforced chassis design can adapt to rugged construction site conditions, forming a mechanized operation chain in conjunction with excavators and loaders. Especially in scenarios such as deep foundation pit excavation and tunnel spoil transportation, dump trucks, through reasonable grouping and scheduling, can ensure that construction progress and safety standards are advanced simultaneously. With intelligent upgrades, some new dump trucks are equipped with Beidou positioning, load monitoring, and anti-rollover early warning systems, further reducing operating costs while promoting the transformation of engineering construction towards green and intelligent directions.

[0003] To prevent cargo spillage and meet environmental protection requirements, tarpaulins need to be installed on the top of the truck bed to cover the cargo. In actual operation, sometimes the tarpaulin fails to completely cover the cargo at the rear of the truck bed, which can easily cause cargo spillage, dust, and certain safety hazards. Therefore, this utility model provides a simple tarpaulin device for dump trucks. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model discloses a simple dump truck tarpaulin device, comprising a cargo box, a motor fixedly installed at the upper front end of the motor of the cargo box, and a tarpaulin assembly for raising and laying the dump truck tarpaulin connected to the motor. The tarpaulin assembly includes two sets of symmetrically distributed linkage mechanisms for assisting in raising and laying the tarpaulin. The tarpaulin assembly also includes a tarpaulin, which includes a front part and a rear part. A suspension beam is fixedly connected to one end of the rear part of the tarpaulin, and the suspension beam itself is heavy.

[0005] Furthermore, a tarpaulin winding tube is fixedly connected to one end of the front of the tarpaulin. The tarpaulin winding tube is rotatably installed on the upper part of the front end of the box body, and the tarpaulin winding tube is connected to the output end of the motor through a coupling.

[0006] Furthermore, the linkage mechanism includes a fixing member and a swing arm. The fixing member is fixedly installed on the side of the compartment, and a cylinder is rotatably installed on the fixing member. One end of the swing arm is rotatably installed on the side of the compartment, and the cylinder arm of the cylinder is rotatably connected to one end near the swing arm.

[0007] Furthermore, the tarpaulin assembly also includes a swing arm beam, which is connected to the rear of the tarpaulin, and both ends of the swing arm beam are rotatably connected to the other ends of the two swing arms, respectively.

[0008] Furthermore, the motor is a waterproof motor.

[0009] The advantages of this utility model compared with the prior art are: This utility model uses a motor, cylinder, swing arm, swing arm beam and suspension beam to completely cover the goods with tarpaulin, which not only saves manpower, but also ensures that environmental protection requirements are met and prevents the goods from spilling. At the same time, the device can be used multiple times. Attached Figure Description

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] Example: Figure 1 , Figure 2 As shown, a simple dump truck tarpaulin device includes a body 10. A motor 1 is fixedly installed on the upper front end of the motor 1 of the body 10. The motor 1 is a waterproof motor. A tarpaulin assembly for raising and lowering the dump truck tarpaulin is connected to the motor 1. The tarpaulin assembly includes two sets of symmetrically distributed linkage mechanisms for assisting in raising and lowering the tarpaulin. The tarpaulin assembly also includes a tarpaulin, which includes a front part 3 and a rear part 5. A suspension beam 6 is fixedly connected to one end of the rear part 5. The suspension beam 6 has a large weight. Through the above scheme, the suspension beam 6 keeps the tarpaulin in a taut state during the laying and raising process. The taut tarpaulin during the raising process is easy to wrap around the tarpaulin winding tube 2.

[0017] One end of the front part 3 of the tarpaulin is fixedly connected to the tarpaulin winding tube 2. The tarpaulin winding tube 2 is rotatably installed on the upper part of the front end of the box body 10. The tarpaulin winding tube 2 is connected to the output end of the motor 1 through a coupling. Through the above scheme, during the process of folding up the tarpaulin, the motor 1 drives the tarpaulin winding tube 2 to rotate in the opposite direction through the coupling. The tarpaulin winding tube 2 winds the tarpaulin. During the process of laying the tarpaulin, the motor 1 drives the tarpaulin winding tube 2 to rotate through the coupling. The tarpaulin wound on the tarpaulin winding tube 2 is released. Then, through the cooperation of the linkage mechanism and the suspension beam 6, the tarpaulin is laid on the box body 10.

[0018] The linkage mechanism includes a fixing member 9 and a swing arm 7. The fixing member 9 is fixedly installed on the side of the body 10. A cylinder 8 is rotatably installed on the fixing member 9. One end of the swing arm 7 is rotatably installed on the side of the body 10. The cylinder arm of the cylinder 8 is rotatably connected to one end of the swing arm 7. Through the above scheme, the cylinder 8 drives the swing arm 7 to rotate around the fixing member 9, which assists in the laying and taking down of the tarpaulin.

[0019] The tarpaulin assembly also includes a swing arm beam 4, which is connected to the rear part 5 of the tarpaulin. Both ends of the swing arm beam 4 are rotatably connected to the other ends of two swing arms 7 respectively. Through the above scheme, the swing arm beam 4 and the suspension beam 6 work together to keep the tarpaulin taut during the folding and laying process.

[0020] In daily use, when the dump truck needs to use a tarpaulin, the motor 1 and cylinder 8 are started. The output of the motor 1 drives the tarpaulin winding tube 2 to rotate via a coupling. The rotation of the tarpaulin winding tube 2 releases the tarpaulin. The cylinder arms of the two cylinders 8 drive the two swing arms 7 to rotate on the body 10. The two swing arms 7 together drive the swing arm beam 4 to rotate. The swing arm beam 4 assists in releasing the tarpaulin from the tarpaulin winding tube 2. During the movement of the swing arm beam 4, the suspension beam 6 always hangs naturally due to its own weight, thus keeping the tarpaulin in a tight position. In the taut state, after the swing arm beam 4 moves to its position, the tarpaulin completely covers the body 10. When the dump truck does not need to use the tarpaulin, the motor 1 and cylinder 8 are started when the tarpaulin is retracted. The motor 1 reverses, and the motor 1 drives the tarpaulin winding tube 2 to reverse through the coupling, so that the tarpaulin is wrapped around the tarpaulin winding tube 2. The cylinder arm of the cylinder 8 retracts, and the cylinder arm of the cylinder 8 pulls the swing arm 7 to move, so that the other end of the swing arm 7 moves from the rear end of the body 10 to the front end of the body 10, thereby assisting the tarpaulin to be wrapped into the tarpaulin winding tube 2, so as to realize the tarpaulin recovery.

[0021] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. The waterproof motor, cylinder, and coupling proposed in this embodiment are all commercially available products, and their working principles and usage methods will not be elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
