[0031] Example 1

[0032] The present embodiment provides a rollover dump truck, that is, a dump truck with a car body 15 that can roll over. The rollover dump truck includes a frame 14 and a car body 15. The car body 15 is rotatably connected to the frame 14. The rotatable connection is preferably a detachable rotatable connection. The front and rear parts of the frame 14 are respectively provided with hydraulic lifting devices 1. The lower end of the hydraulic lifting device 1 is rotatably installed on the left part of the frame 14, and the upper end of the hydraulic lifting device 1 is rotatably connected to the car body 15.

[0033] Compared with the conventional side-rollover dump truck in which the side-rollover lifting device is arranged at the lower part of the car body 15, the present invention is provided with a hydraulic lifting device 1, which is arranged at the front and rear of the frame 14, that is, the hydraulic lifting device 1 is located at the front and rear of the car body 15, and the hydraulic lifting device 1 is exposed to the outside, which is convenient for the staff to disassemble, repair and maintain the hydraulic lifting device 1. At the same time, the lower end of the hydraulic lifting device 1 is rotatably connected to the frame 14, and the upper end is rotatably connected to the car body 15. The rotatable connection can be any rotatable connection mode such as the hinge seat 9 connection. The rotatable connection is located outside, and the staff can conveniently separate the hydraulic lifting device 1 from the car body 15, thereby making the car body 15 in an independent and free state. When the car body 15 is an independent body such as a container, and the rotatable connection with the frame 14 is disconnected, the staff can lift the car body 15 as a whole from the frame 14, thereby improving the convenience of use of the side-rollover dump truck.

[0034] Specifically, in the present embodiment, the rotational connection between the hydraulic lifting device 1 and the carriage 15 may be any hinge connection such as a hinge seat 9, and the carriage 15 and the upper end of the hydraulic lifting device 1 may be directly connected or indirectly connected. In order to improve the stability of the connection between the carriage 15 and the hydraulic lifting device 1, a connecting member is provided at the upper end of the hydraulic lifting device 1, and the connecting member includes a crossbeam 2, and the crossbeam 2 is used to connect the carriage 15. The connection between the crossbeam 2 and the carriage 15 may be through any existing connection method such as bolts, clamping, locking members, etc. The connection between the hydraulic lifting device 1 and the crossbeam 2, the hydraulic lifting device 1 can be directly rotatably installed on the lower part of the crossbeam 2, such as providing a hinge seat at the lower part of the crossbeam 2, through the above method, the rotational connection of the upper end of the hydraulic lifting device 1 is facilitated, and the stability of the connection is improved.

[0035] More specifically, in order to control the trajectory of the upper end of the hydraulic lifting device 1 and the angle of the hydraulic lifting device 1, a vertical beam 3 is provided at the upper end of the hydraulic lifting device 1, and the lower end of the vertical beam 3 is rotatably connected to the right part of the frame 14; of course, the upper end of the hydraulic lifting device must also be rotatably connected to the carriage. Through the above arrangement, the upper end of the hydraulic lifting device 1 can be rotated with the rotation connection at the lower part of the vertical beam 3 as the axis, avoiding the hydraulic lifting device 1 from directly lifting upward.

[0036] Specifically, in the present embodiment, in order to control the trajectory of the upper end of the hydraulic lifting device 1 and to facilitate the rotational connection with the carriage 15: a vertical beam 3 is provided at the upper end of the hydraulic lifting device 1, and the lower end of the vertical beam 3 is rotationally connected to the right part of the frame 14. The trajectory of the upper end of the hydraulic lifting device 1 is limited by the setting of the vertical beam 3, so that the hydraulic lifting device 1 pushes the carriage 15 to overturn; at the same time, a cross beam 2 extending to the left is also provided at the upper end of the vertical beam 3, and the cross beam 2 is used to connect the carriage 15, and the upper end of the hydraulic lifting device 1 is rotationally connected to the cross beam 2 or the vertical beam 3.

[0037] More specifically, in this embodiment, the rotation connection between the carriage 15 and the frame 14 can be a direct connection between the carriage 15 and the frame 14, or an indirect connection between the carriage 15 and the frame 14. The rotation connection between the carriage 15 and the frame 14 only means that the carriage 15 can be turned leftward or backward on the frame 14. This embodiment also provides the following indirect connection method: a mounting plate 11 is also provided on the inner side of the cross beam 2, and the mounting plate 11 and the carriage 15 are connected together. The carriage 15 is mounted on the cross beam 2 and the vertical beam 3 through the mounting plate 11, and the carriage 15 is turned while the hydraulic lifting device 1 pushes the cross beam 2 and the vertical beam 3 to turn over. The carriage 15 is indirectly rotationally connected to the frame 14 through the cross beam 2 and the vertical beam 3. The setting of the mounting plate 11 can not only be used to connect the carriage 15, but also can isolate the carriage 15 from the hydraulic lifting device 1, the cross beam 2 and the vertical beam 3, so as to protect the hydraulic lifting device 1, the cross beam 2 and the vertical beam 3.

[0038] More specifically, in this embodiment, in order to fix the carriage 15 and the mounting plate 11 together, the carriage 15 and the mounting plate 11 can be connected by any means such as bolts, clamps, etc. At the same time, in order to facilitate the support of the carriage 15, a new method for installing and fixing the carriage 15 is provided. The lower part of the mounting plate 11 is provided with a seat plate 12 extending toward the middle part of the frame 14. The seat plate 12 should be the mounting seat 4 for fixing the carriage 15. The seat plate 12 is provided with a locking member, and the locking member is used to connect the carriage 15.

[0039] More specifically, in the present embodiment, the locking member can be any existing device for fixing the carriage 15 and the seat plate 12 together, such as clamping, bolting, welding, etc., but in the present embodiment, a connection method that is easy to operate and easy to disassemble is provided: the locking member is a container lock 13, and the carriage 15 is provided with an installation hole that is compatible with the container lock 13.

[0040] Specifically, in this embodiment, the frame 14 and the carriage 15 can also be directly connected, that is, a hinge seat 9 is provided at the right part of the frame 14, and the hinge seat 9 is rotatably connected to the carriage 15. The hinge seat 9 is any hinge connection method in the prior art, such as two hinge plates arranged in parallel, a rotating shaft is provided between the hinge plates, and the carriage 15 is installed on the rotating shaft.

[0041] More specifically, the hinge seat 9 is subjected to a large force when the vehicle body 15 rolls over, and the present embodiment further provides an installation position of the hinge seat 9, that is, the vehicle frame 14 includes a longitudinal beam 10 and a support beam 7 extending outward from the longitudinal beam 10, and the hinge seat 9 is arranged at the outer end of the support beam 7. The support beam 7 can pass through the two longitudinal beams 10 of the vehicle frame 14, or can be a support beam 7 independently arranged on one side of the longitudinal beam 10.

[0042] More specifically, in order to improve the strength of the supporting crossbeam 7 , the supporting crossbeam 7 is also connected to an inclined beam 8 , the upper end of the inclined beam 8 is connected to the middle part or near the outer end of the crossbeam 2 , and the lower end of the inclined beam 8 is connected to the longitudinal beam 10 .

[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.
