Description

Technical Field

[0001] The present application relates to the technical field of automobile cargo boxes, and in particular to a dump truck cargo box and a dump truck. Background Art

[0002] The traditional dump truck superstructure primarily consists of a floor, front panel, side panels, tailgate, and lifting mechanism. Unloading is primarily powered by the truck chassis, with a power take-off driving a hydraulic pump that raises the lifting cylinder to a certain height for unloading. While simple and straightforward, this method has significant limitations when working with dense underground pipelines, steep slopes, or confined spaces. For example, it can easily damage surrounding facilities, posing a safety risk. Traditional unloading methods and cargo boxes, such as front or center lifts, are no longer suitable in these environments. Summary of the Invention

[0003] The purpose of the present application is to provide a dump truck cargo box and a dump truck, which are used to solve the problem that traditional dump trucks in the prior art have great limitations when encountering working conditions with dense underground pipelines, steep slopes or narrow spaces.

[0004] To solve the above technical problems, this application is implemented by adopting the following technical solutions:

[0005] On the one hand, the present application provides a dump truck cargo box, comprising: a box bottom and a first side panel and a second side panel respectively arranged perpendicularly on both sides of the box bottom, characterized in that the box bottom comprises:

[0006] A driving shaft is provided between the first side panel and the second side panel, and is axially perpendicular to the opposite side surfaces of the first side panel and the second side panel, and two ends of the driving shaft are rotatably connected to the first side panel and the second side panel respectively;

[0007] The driven assembly includes a plurality of transverse shafts, wherein the plurality of transverse shafts are arranged parallel to the driving shaft between the first side plate and the second side plate, and the plurality of transverse shafts and the driving shaft are located at the same height position as the first side plate and the second side plate, and the two ends of each transverse shaft are fixedly connected to the first side plate and the second side plate respectively, and a rolling cylinder is sleeved on the transverse shaft;

[0008] A conveyor belt is sleeved on the driving shaft and the outer wall of the rolling drum;

[0009] A driving member is used to drive the driving shaft to rotate.

[0010] In this solution, the driving shaft, the driven shaft and the conveyor belt together constitute the supporting structure of the bottom of the box, which can support the placement of goods during transportation. When unloading operations are required, the driving part starts, driving the driving shaft to rotate. Since the conveyor belt is mounted on the driving shaft and the outer wall of the rolling drum, the rotation of the driving shaft will drive the conveyor belt to start moving. The goods are placed on the conveyor belt, and as the conveyor belt moves, the goods are gradually transported out of the cargo box to achieve unloading. In some cases, this solution can also load goods by controlling the direction of operation of the driving part. For example: placing goods on the conveyor belt on the unloading side of the cargo box, the goods can be transported to the other side of the cargo box by controlling the direction of operation of the driving part. There is no need for manual entry into the cargo box for handling, which effectively improves the efficiency of loading and unloading.

[0011] Compared to traditional dump trucks that rely on lifting the cargo box to unload, this conveyor belt method eliminates the need for significant cargo box lifting. This effectively avoids collision risks in environments with dense underground pipelines, steep slopes, or confined spaces. Furthermore, by controlling the speed and direction of the drive components, the speed and direction of loading and unloading can be flexibly controlled, improving loading and unloading efficiency.

[0012] Optionally, a longitudinal beam is vertically arranged on the horizontal axis, the bottom of the longitudinal beam is connected to the subframe, the longitudinal beam includes a first longitudinal beam and a second longitudinal beam arranged in parallel, and the conveyor belt includes a first conveyor belt arranged between the first longitudinal beam and the first side panel, a second conveyor belt arranged between the first longitudinal beam and the second longitudinal beam, and a third conveyor belt arranged between the second longitudinal beam and the second conveyor belt.

[0013] In this solution, the bottom of the longitudinal beam connects to the subframe, integrating the box bottom with the vehicle chassis and improving its support capacity. Furthermore, the longitudinal beam divides the conveyor belt into three sections. Each section has supports on both sides of the horizontal axis to prevent stress concentration and bending deformation caused by prolonged cargo loading. By using multiple conveyor belts to coordinate cargo unloading, the operation is more stable. Furthermore, if a conveyor belt becomes damaged, only the corresponding belt needs to be replaced, eliminating the need to replace the entire belt, thus reducing maintenance costs.

[0014] Optionally, a first sprocket is provided on the driving shaft between the second conveyor belt and the third conveyor belt.

[0015] Optionally, the driving component includes an upper motor, which is fixedly connected to the sub-frame, and a second sprocket is sleeved on the output shaft of the upper motor, and the first sprocket is connected to the second sprocket via a chain transmission.

[0016] This solution places the sprocket between the second and third conveyor belts, fully utilizing the space at the bottom of the box and making it more compact. The upper motor and drive shaft are connected via a chain drive, which provides a precise transmission ratio and high efficiency, ensuring stable and reliable transmission of the upper motor's power to the drive shaft.

[0017] Optionally, first bearings are respectively sleeved on both ends of the driving shaft, and two outer rings of the first bearings are respectively fixedly connected to the first side plate and the second side plate.

[0018] In this solution, first bearings are sleeved on both ends of the driving shaft, and the outer rings of the bearings are fixedly connected to the side plates. The arrangement of the first bearings greatly reduces the friction resistance encountered by the driving shaft during rotation, thereby improving transmission efficiency.

[0019] Optionally, a second bearing is provided between the transverse axis and the rolling cylinder.

[0020] This solution sets a second bearing between the horizontal axis and the rolling drum, which also reduces the friction resistance encountered by the rolling drum during rotation, allowing the rolling drum to rotate more easily under the drive of the conveyor belt, reducing the driving force required for the rotation of the rolling drum, and ensuring that the rolling drum rotates more smoothly.

[0021] Optionally, the dump truck cargo box further comprises: a tailgate, rotating parts are provided on both sides of the top of the tailgate, and fixing parts hingedly connected to the rotating parts are provided on the top of the first side panel and the second side panel.

[0022] This solution hinges the rotating parts on both sides of the top of the car tailgate to the fixing parts on the top of the first side panel and the second side panel, so that the car tailgate can rotate around the hinge point to realize the opening and closing operations of the car tailgate.

[0023] Optionally, lifting rods are provided on both sides of the tailgate of the vehicle, and lifting hydraulic cylinders are provided on the first side panel and the second side panel. The movable end of the lifting hydraulic cylinder is rotatably connected to the lifting rod, and the rotating part and the fixed part can be driven to rotate relative to each other through the extension and retraction of the movable end of the lifting hydraulic cylinder.

[0024] This solution uses a hydraulic lift cylinder to automatically open and close the tailgate. Specifically, the movable end of the hydraulic lift cylinder is rotatably connected to the lift rods on either side of the tailgate. By controlling the extension and retraction of the movable end of the hydraulic lift cylinder, the rotating and fixed parts rotate relative to each other, thereby achieving automated opening and closing of the tailgate. This solution improves unloading efficiency through automated operation and reduces the labor intensity and time costs of manual operation.

[0025] On the other hand, the present application provides a dump truck comprising the above-mentioned dump truck cargo box.

[0026] Compared with the prior art, the beneficial effects achieved by the present application are as follows: the present application uses a driving shaft, a driven shaft and a conveyor belt to form a support structure for the bottom of the box, which can support and place the goods during transportation. When unloading operations are required, the driving member starts, driving the driving shaft to rotate. Since the conveyor belt is sleeved on the driving shaft and the outer wall of the rolling drum, the rotation of the driving shaft will drive the conveyor belt to start moving. The goods are placed on the conveyor belt, and as the conveyor belt moves, the goods are gradually transported out of the cargo box to achieve unloading. Compared with the traditional dump truck method of relying on lifting the cargo box to unload, the present application does not require a large lifting action on the cargo box during the unloading process. In working conditions with dense underground pipelines, steep slopes or narrow spaces, it can effectively avoid risks such as collisions with surrounding objects. At the same time, the present application can also achieve flexible control of the speed and direction of loading and unloading of goods by controlling the operating speed and direction of the driving member, thereby improving the efficiency of loading and unloading.

DETAILED DESCRIPTION

[0032] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application, its application, or use.

[0033] Example 1

[0034] This embodiment introduces a dump truck container and a dump truck device. Figures 1 to 3 The dump truck cargo box in this embodiment includes: a box bottom 1 and a first side panel 2 and a second side panel 3 respectively arranged perpendicularly on both sides of the box bottom. The box bottom 1 includes: a driving shaft 11, a driven assembly 12, a conveyor belt 13, and a driving assembly. The driving shaft 11 is arranged between the first side panel 2 and the second side panel 3 and is axially perpendicular to the opposite sides of the first side panel 2 and the second side panel 3. The two ends of the driving shaft 11 are respectively rotatably connected to the first side panel 2 and the second side panel 3. The driven assembly 12 includes a plurality of transverse shafts 121. The plurality of transverse shafts 121 are arranged parallel to the driving shaft 11 and between the first side panel 2 and the second side panel 3. The plurality of transverse shafts 121 and the driving shaft 11 are located at the same height as the first side panel 2 and the second side panel 3. The two ends of each transverse shaft 121 are respectively fixedly connected to the first side panel 2 and the second side panel 3. A roller 122 is sleeved on the transverse shaft 121. The conveyor belt 13 is sleeved on the outer walls of the driving shaft 11 and the roller 122. The driving member 15 is used to drive the driving shaft 11 to rotate.

[0035] In this embodiment, the driving shaft 11, the driven shaft and the conveyor belt 13 together constitute the support structure of the bottom 1 of the box, which can support the placement of goods during transportation. When unloading operations are required, the driving member 15 is started to drive the driving shaft 11 to rotate. Since the conveyor belt 13 is sleeved on the driving shaft 11 and the outer wall of the rolling drum 122, the rotation of the driving shaft 11 will drive the conveyor belt 13 to start moving. The goods are placed on the conveyor belt 13, and as the conveyor belt 13 moves, the goods are gradually transported out of the cargo box to achieve unloading. In some cases, this embodiment can also load goods by controlling the running direction of the driving member 15. For example: the goods are placed on the conveyor belt 13 on the unloading side of the cargo box, and the running direction of the driving member 15 can be controlled to transport the goods to the other side of the cargo box, without the need for manual entry into the cargo box for handling, which effectively improves the efficiency of loading and unloading. Compared to traditional dump trucks that rely on lifting the cargo box to unload, this embodiment's unloading method using conveyor belt 13 eliminates the need for significant cargo box lifting. This effectively avoids risks such as collisions with surrounding objects in environments with dense underground pipelines, steep slopes, or confined spaces. Furthermore, by controlling the speed and direction of the drive element 15, the speed and direction of loading and unloading can be flexibly controlled, improving loading and unloading efficiency.

[0036] Example 2:

[0037] Based on the same inventive concept as the first embodiment, refer to Figure 2 and Figure 3 In this embodiment, a longitudinal beam 14 is perpendicularly mounted on the transverse axis 121. The bottom of the longitudinal beam 14 is connected to the subframe 7, integrating the box bottom 1 with the vehicle chassis and enhancing its support capacity. The longitudinal beam 14 includes a first longitudinal beam 141 and a second longitudinal beam 142 arranged in parallel. The conveyor belt 13 includes a first conveyor belt 131 disposed between the first longitudinal beam 141 and the first side panel 2, a second conveyor belt 132 disposed between the first longitudinal beam 141 and the second longitudinal beam 142, and a third conveyor belt 133 disposed between the second longitudinal beam 142 and the second conveyor belt 132. In this embodiment, the longitudinal beam 14 divides the conveyor belt 13 into three sections. Each section of the conveyor belt 13 has supports on both sides of the transverse axis 121 to prevent stress concentration and bending deformation caused by prolonged cargo loading. It should be noted that in this embodiment, the top of the longitudinal beam 14 does not protrude from the outer surface of the conveyor belt 13. By using multiple conveyor belts 13 to coordinate cargo unloading, the operation is more stable. Furthermore, when a certain conveyor belt 13 is damaged, only the corresponding conveyor belt 13 needs to be replaced, without replacing the entire conveyor belt 13, thereby reducing maintenance costs.

[0038] In this embodiment, a first sprocket 112 is provided on the driving shaft 11 between the second conveyor belt 132 and the third conveyor belt 133. By arranging the sprocket between the second conveyor belt 132 and the third conveyor belt 133, the spatial structure of the box bottom 1 is fully utilized, making the structure of the box bottom 1 more compact. Furthermore, the driving member 15 includes an upper motor 151, which is fixedly connected to the subframe 7. A second sprocket 152 is sleeved on the output shaft of the upper motor 151, and the first sprocket 112 and the second sprocket 152 are connected by a chain 153. In this embodiment, the upper motor 151 is connected to the driving shaft 11 by a chain 153, and the transmission ratio is accurate and the efficiency is high, which can ensure that the power output by the upper motor 151 is stably and reliably transmitted to the driving shaft 11.

[0039] To improve the transmission efficiency of the drive shaft 11 and the rolling drum 122, in this embodiment, first bearings 111 are mounted on both ends of the drive shaft 11, with the outer rings of the bearings fixedly connected to the side plates. The provision of the first bearings 111 significantly reduces the frictional resistance experienced by the drive shaft 11 during rotation, thereby improving transmission efficiency. A second bearing 123 is positioned between the transverse shaft 121 and the rolling drum 122. This second bearing 123 also reduces the frictional resistance experienced by the rolling drum 122 during rotation, allowing it to rotate more easily under the drive of the conveyor belt 13. This reduces the driving force required to rotate the rolling drum 122 and ensures smoother rotation.

[0040] Example 3:

[0041] Based on the same inventive concept as the first embodiment, refer to Figure 1 The dump truck cargo box of this embodiment further includes a tailgate 4 and a front panel 5. The front panel 5 is connected to the first side panel 2 and the second side panel 3, and the tailgate is disposed opposite the front panel 5. Rotating members 41 are disposed on either side of the top of the tailgate 4, and fixed members 42 are hingedly connected to the rotating members 41 at the tops of the first and second side panels 2 and 3. The hinged connection between the rotating members 41 disposed on either side of the top of the tailgate 4 and the fixed members 42 disposed on the tops of the first and second side panels 2 and 3 allows the tailgate 4 to rotate about the hinge point, thereby enabling the tailgate 4 to be opened and closed.

[0042] Furthermore, this embodiment utilizes a lifting hydraulic cylinder 6 to automatically open and close the tailgate 4. Specifically, lifting rods 43 are located on either side of the tailgate 4. Lifting hydraulic cylinders 6 are installed on the first and second side panels 2 and 3. The movable end of the lifting hydraulic cylinder 6 is pivotally connected to the lifting rod 43. The extension and retraction of the movable end of the lifting hydraulic cylinder 6 drives the relative rotation of the rotating member 41 and the fixed member 42, thereby achieving automated opening and closing of the tailgate 4. This embodiment improves unloading efficiency through automated operation and reduces the labor intensity and time costs of manual operation.

[0043] Example 4:

[0044] This embodiment introduces a dump truck. The dump truck in this embodiment includes the dump truck cargo box provided by any one of the first to third embodiments.

[0045] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present disclosure / application. These improvements and modifications should also be regarded as the scope of protection of the present disclosure / application.
