One end of the tipping oil cylinder is hinged to the bottom surface of the carriage, and the other end of the tipping oil cylinder is hinged to the vehicle frame.

[0004] The above-mentioned crawler transport vehicle uses the traditional backward tipping method for unloading, which has the problem of high risk of center of gravity imbalance.

Detailed implementation manners

[0048] The following combines the accompanying drawings and embodiments to further describe the detailed implementation manners of the present invention. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention.

[0049] As Figure 1-14As shown in the figure, the crawler transporter of the present invention includes: a vehicle body 100; a power assembly 200, including a crawler assembly 210 connected to the vehicle body 100 for driving the movement of the vehicle body 100; a carriage assembly 300, including a cargo box 310 rotatably connected to the vehicle body 100, the axis of the rotation shaft of the cargo box 310 being parallel to the length direction of the vehicle body 100, and a rotation assembly for driving the rotation of the cargo box 310 is provided between the cargo box 310 and the vehicle body 100; a power source assembly 400 for providing a power source to the power assembly 200 and the rotation assembly.

[0050] With such a design, the cargo box 310 is tilted for unloading along its long side. Compared with the way of tilting and unloading along its short side, the height change of the cargo box 310 is small, the space requirement is low, and at the same time, the change range of the center of gravity is small, improving the unloading safety of the crawler transporter.

[0051] As Figure 2 Figure 3 As shown in the figure, according to an embodiment of the present invention, the cargo box 310 includes a frame 311, a bottom plate 312 fixedly connected to the frame 311, and side plates 313 rotatably connected to the frame 311, and a locking member 314 is provided between the side plates 313 and the frame 311.

[0052] With such a design, the purpose of the side plates 313 being rotatable to open or close is achieved. When the crawler transporter needs to unload, the locking member 314 is opened, and the side plates 313 are turned down to facilitate the dumping of goods; when the crawler transporter is transporting, the side plates 313 are turned up and fixed to the frame 311 through the locking member 314, achieving the purpose of closing and locking the side plates 313, and the cargo box 310 is closed to facilitate the transportation of goods.

[0053] As Figure 2 Figure 3 As shown in the figure, according to an embodiment of the present invention, the locking member 314 is a seven - character lock. The seven - character lock is a common locking member for cargo boxes, with a simple and durable structure, which not only meets the locking requirements of the locking member 314 but also reduces the cost of the whole vehicle.

[0054] As Figure 2 Figure 3 As shown in the figure, according to an embodiment of the present invention, it further includes a first mounting seat 320 and a second mounting seat 330 fixedly connected to the vehicle body 100, the frame 311 or the bottom plate 312 is rotatably connected to the first mounting seat 320, and the rotation assembly is provided between the second mounting seat 330 and the frame 311 or the bottom plate 312.

[0055] With such a design, the purpose of the rotatable connection between the cargo box 310 and the vehicle body 100 is achieved, and the rotation assembly can drive the cargo box 310 to perform lateral dumping operations.

[0056] As Figure 2 Figure 3 shown, according to an embodiment of the present invention, the rotating assembly includes a first oil cylinder 340. The cylinder block of the first oil cylinder 340 is rotatably connected to the second mounting seat 330, and the piston rod of the first oil cylinder 340 is rotatably connected to the bottom plate 312.

[0057] With such a design, the telescoping of the first oil cylinder 340 can apply a lifting force to the cargo box 310. However, since one side of the cargo box 310 is rotatably connected to the vehicle body 100, the cargo box 310 can only perform a rotational movement, thus achieving the purpose of the lateral tipping of the cargo box 310.

[0058] As Figure 2-4 shown, according to an embodiment of the present invention, a shock-absorbing cushion block 350 is provided between the frame 311 and the first mounting seat 320.

[0059] With such a design, when the cargo box 310 is reset, direct impact between the cargo box 310 and the vehicle body 100 is avoided, and the shock-absorbing cushion block 350 plays a buffering role; at the same time, the shock-absorbing cushion block 350 also plays a role in bearing the cargo box 310.

[0060] As Figure 12 shown, according to an embodiment of the present invention, the power assembly 200 includes a driving wheel 220 and a guide wheel 230 that are rotatably connected to the vehicle body 100.

The axial line direction of the rotation shaft of the shovel plate body 510 is parallel to the width direction of the vehicle body 100.

[0067] Through such a design, the newly added shovel plate assembly 500 enables the tracked transporter to independently complete the tasks of shoveling materials, loading, and transporting, reducing the dependence on additional shoveling equipment, shortening the time-consuming of the operation process, and further achieving the purpose of the multi-function of the tracked transporter.

[0068] As Figure 14 shown, according to an embodiment of the present invention, the first driving assembly includes a second oil cylinder 520. The cylinder body of the second oil cylinder 520 is rotatably connected to the vehicle body 100, and the piston rod of the second oil cylinder 520 is rotatably connected to the shovel plate body 510.

[0069] Through such a design, the purpose of the rotation of the shovel plate body 510 is achieved. When the shovel plate body 510 needs to operate, the shovel plate body 510 is lowered, and when it is not needed, the shovel plate body 510 can be lifted to facilitate the normal movement of the tracked transporter.

[0070] As Figure 7-11 shown, according to an embodiment of the present invention, it further includes a hanging basket assembly 600 connected to the vehicle body 100. The hanging basket assembly 600 includes a hanging basket frame 610, a horizontal adjustment assembly, and a height adjustment assembly for adjusting the position of the hanging basket frame 610.

[0071] Through such a design, the purpose of the multi-functional crawler transporter is achieved. It not only meets the basic transportation function of the crawler transporter but also adds the function of lifting people, and can be used as a temporary manual lift, with strong flexibility.

[0072] As Figure 7 Figure 8 shown, according to an embodiment of the present invention, the hanging basket assembly 600 includes a main arm base 620 and a telescopic arm assembly 630.
