[0032] The present embodiment provides a rear-flip dump truck, which includes a frame and a carriage, the front part of the frame is provided with a rear-flip lifting device 9, and the lower part of the rear-flip lifting device 9 is rotatably connected to the frame. The rear part of the carriage is rotatably connected to the rear part of the frame in a detachable manner, and the upper part of the rear-flip lifting device 9 is rotatably mounted on the carriage in a detachable manner. The frame includes two longitudinal beams arranged longitudinally, and a mounting seat 1 is mounted on the upper part of the longitudinal beams. A hinge seat is also provided on the mounting seat 1, and the lower part of the rear-flip lifting device 9 is rotatably mounted on the hinge seat; the frame is detachably mounted with a hoisting device.

[0033] In the above rear dump truck, the rear part of the carriage is rotatably mounted on the rear part of the frame in a detachable manner, and the detachable manner may be any manner such as the rear rotating shaft can be withdrawn, the rotatable connection seat between the carriage and the frame is detachably mounted by bolts, etc.; at the same time, the upper part of the rear dump lifting device 9 is also rotatably connected to the carriage in a detachable manner. In the above manner, the connection between the carriage and the hydraulic lifting device and the connection between the carriage and the frame can be released, thereby making the carriage independent.

[0034] The frame is also detachably mounted with a lifting device, which can be any lifting device in the prior art that can be mounted on the frame and can lift the car body on the frame, such as an aerial crane, a side arm crane, etc. The lifting device is used to lift the car body from land to the car body, or to lift the car body from the frame. When the car body is in an independent state, the rotation connection between the rear part of the car body and the rear part of the frame is disconnected, and the connection between the upper part of the rear flip lifting device 9 and the car body is disconnected. The lifting device can be mounted on the frame, and the independent car body can be lifted by the lifting device. When the rear flip function needs to be used, the lifting device or the part of the lifting device that affects the rear flip, such as the partial structure of the lifting device at the rear part of the frame, can be removed, the rear part of the frame and the rear part of the car body are rotationally connected, the upper part of the rear flip lifting device 9 is connected to the car body, and the rear flip of the car body is realized by the rear flip lifting device 9. The above-mentioned rear tipping dump truck can select different modes as needed to enable the rear tipping dump truck to realize the function of rear tipping or the function of hoisting the carriage by the side arm. Of course, when the carriage needs to be hoisted, the carriage should preferably be a container-type carriage.

[0035] Specifically, in this embodiment, when the lifting device is a side arm lifting structure, in order to install the side arm lifting structures located at the front and rear of the frame respectively, the mounting seat 1 includes a front mounting seat 1 located at the front and a rear mounting seat 1 located at the rear. The side arm lifting structure is installed on each mounting seat 1, and the rear mounting seat 1 is installed on the frame in a detachable manner. That is, when the rear-flip dump truck needs to be flipped backward, the rear mounting seat 1 and the side arm lifting structure thereon should be removed. When it is not necessary to flip backward, the side arm lifting structures are respectively arranged on the front mounting seat and the rear mounting seat. At this time, the rear-flip dump truck appears as follows: Figure 1 The style shown forms a side self-loading semi-trailer.

[0036] More specifically, in this embodiment, the side arm suspension structure includes a vertical beam 2 extending upward from the left end of the mounting seat 1 , and a horizontal beam 3 extending to the right is provided at the upper end of the vertical beam 2 .

[0037] More specifically, the side arm crane structure further includes a cross beam 3 lifting device for lifting the cross beam 3 and a hoisting machine or supporting equipment located on the cross beam 3, and the cross beam 3 lifting device and the hoisting machine or supporting equipment are detachably mounted on the rear tipping dump truck. That is, when disassembly is required, all components other than the cross beam 3 and the vertical beam 2 on the side arm crane structure that affect the rear tipping can be removed.

[0038] More specifically, in the present embodiment, a support beam 6 extending upward is further provided in the middle of the mounting seat 1 , and the hinge seat is provided on the support beam 6 .

[0039] More specifically, the present embodiment also provides a specific form of the hinge seat, that is, the hinge seat includes a mounting plate 7, and the mounting plate 7 is fixed on the support beam 6; the mounting plate 7 is provided with a hinge plate 8 extending away from the middle of the frame, and the hinge plate 8 is provided with a pin shaft hole, and the pin shaft hole is provided with a pin shaft, and the mounting seat 1 of the rear flip lifting device 9 is rotatably installed on the pin shaft.

[0040] More specifically, in order to improve the installation stability of the hinge seat, two support beams 6 are provided, and the mounting plate 7 is fixed on the two support beams 6 .

[0041] More specifically, in order to improve the strength of the support beam 6, the upper part of the support beam 6 is connected to the cross beam 3 in a detachable manner. That is, when the back flip is required, the support beam 6 is used to support the back flip lifting device 9. At this time, the support beam 6 is subjected to a large force. For this reason, when the lifting device is a side arm lifting structure arranged on the mounting seat 1, the side arm lifting structure includes a vertical beam 2 extending upward from the left end of the mounting seat 1, and the upper end of the vertical beam 2 is provided with a cross beam 3 extending to the right, and the upper part of the support beam 6 is installed on the cross beam 3. Of course, when the car needs to be lifted, in order to avoid interfering with the movement of the cross beam 3, the connection between the support beam 6 and the cross beam 3 should be disconnected.

[0042] Specifically, in this embodiment, the connection strength between the car body and the frame must be ensured during normal driving of the rear-flip dump truck, but during lifting and rollover, the front of the car body and the frame do not need to be connected. For this purpose, an extension portion 4 is provided on one side of the mounting seat 1 close to the middle of the car body, and a container lock 5 is provided on the extension portion 4, and a lock hole corresponding to the container lock 5 is provided on the car body.

[0043] Of course, the above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept of the utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the utility model and should be protected by the utility model.
