Detailed Implementation

[0068] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0069] like Figures 1-14 As shown, the tracked transport vehicle with bidirectional tilting cargo box of this utility model includes: a vehicle body 100; a power assembly 200, including a track assembly 210 connected to the vehicle body 100 for driving the movement of the vehicle body 100; a cargo box assembly 300, including a cargo box 310 rotatably connected to the vehicle body 100, wherein the axis of rotation of the cargo box 310 is parallel to the length direction of the vehicle body 100, and a rotating assembly for driving the cargo box 310 to rotate is provided between the cargo box 310 and the vehicle body 100; and a power source assembly 400 for providing a power source to the power assembly 200 and the rotating assembly.

[0070] With this design, the cargo box 310 tilts and unloads along its long side. Compared with the tilting and unloading method along its short side, the cargo box 310 has a smaller height change, lower space requirements, and a smaller range of center of gravity change, which improves the unloading safety of the tracked transport vehicle.

[0071] like Figure 2 Figure 3 As shown, according to one embodiment of the present invention, the cargo box 310 includes a frame 311, a bottom plate 312 fixedly connected to the frame 311, and a side plate 313 rotatably connected to the frame 311. A locking member 314 is provided between the side plate 313 and the frame 311.

[0072] This design allows the side panel 313 to be flipped open or closed.

[0088] like Figure 14 As shown, according to one embodiment of the present invention, the first drive assembly includes a second hydraulic cylinder 520, the cylinder body of the second hydraulic cylinder 520 is rotatably connected to the vehicle body 100, and the piston rod of the second hydraulic cylinder 520 is rotatably connected to the shovel plate body 510.

[0089] This design enables the shovel body 510 to rotate; when the shovel body 510 needs to operate, it can be lowered, and when not needed, it can be raised to facilitate the normal movement of the tracked transport vehicle.

[0090] like Figures 7-11 As shown, according to one embodiment of the present invention, it further includes a basket assembly 600 connected to the vehicle body 100; the basket assembly 600 includes a basket frame 610 and a horizontal adjustment component and a height adjustment component for adjusting the position of the basket frame 610.

The leveling component 660 includes a leveling arm 661 fixedly connected to the inner cylinder 633, a connecting frame 662 rotatably connected to the leveling arm 661, and a sixth hydraulic cylinder 663 disposed between the leveling arm 661 and the connecting frame 662. The cylinder body of the sixth hydraulic cylinder 663 is rotatably connected to the leveling arm 661, and the piston rod of the sixth hydraulic cylinder 663 is rotatably connected to the connecting frame 662. The axis of rotation of the sixth hydraulic cylinder 663 is horizontally oriented, and the suspended basket frame 610 is fixedly connected to the connecting frame 662.

[0107] This design ensures that the suspended platform frame 610 remains horizontal at any height and position, preventing tilting when workers are standing inside the suspended platform frame 610 and ensuring the safety of workers.

[0108] like Figure 7 Figure 8 As shown, according to one embodiment of the present invention, the outer cylinder 631 is provided with a hydraulic winch 670, and the end of the inner cylinder 633 is rotatably provided with a pulley 671 that cooperates with the winch rope of the hydraulic winch 670.

[0109] This design adds the functionality of a crane to the tracked transporter, reduces its reliance on cranes, further enhances the multi-functionality of the tracked transporter, and improves its practicality in tunnels.

[0110] Example 2

[0111] like Figures 2-6 As shown, Example 2 is based on Example 1, with the following differences:

[0112] According to one embodiment of the present invention, the cargo box 310 is configured for bidirectional tilting.

[0113] With this design, tracked transporters can choose to tilt to the left or right when unloading, depending on the actual conditions in the tunnel, avoiding the difficulty of turning around in the tunnel and improving the convenience of unloading.

[0114] According to one embodiment of the present invention, both ends of the first mounting base 320 are provided with pivot holes 321, and both ends of the frame 311 are fixedly provided with third mounting bases 360. The third mounting base 360 ​​is provided with a pin hole coaxial with the pivot hole 321; it also includes a pin that passes through the pin hole and the pivot hole 321, and the pin is detachably fixedly connected to the pivot hole 321.

[0115] With this design, both sides of the cargo box 310 can be rotatably connected to the first mounting base 320. Simply insert the pin into the pivot hole 321 on the corresponding side to achieve the purpose of rotating the cargo box 310 along that side.

[0116] According to one embodiment of the present invention, the pin includes a pin body 371 and a limiting block 372 fixedly connected to the pin body 371. The pin body 371 passes through the rotating shaft hole 321. The limiting block 372 abuts against the side wall of the first mounting base 320. The limiting block 372 and the first mounting base 320 are fixedly connected by bolts 373.

[0117] With this design, the pin body 371 is fixed to the first mounting base 320 by a fixed connection between the limiting block 372 and the first mounting base 320. The limiting block 372 and the first mounting base 320 are fixedly connected by bolts 373. Since the pin body 371 is fixedly connected to the limiting block 372, the pin body 371 is fixedly connected to the first mounting base 320. The setting of bolts 373 achieves the purpose of making the pin detachable.

[0118] According to one embodiment of the present invention, a limiting arc plate 322 is fixedly provided on the side wall of the first mounting base 320, and the limiting arc plate 322 is abutted against the limiting block 372.

[0119] With this design, the limiting block 372 is limited by the arc-shaped limiting plate 322, which prevents the pin from rotating. The pin is limited by the bolt 373 and the arc-shaped limiting plate 322, which reduces the pressure between the pin body 371 and the shaft hole 321.

[0120] According to one embodiment of the present invention, the pin body 371 is provided with a lubricating oil channel 374 and a lubricating oil inlet 375, and the side wall of the pin is provided with a lubricating oil receiving groove 376, which is connected to the lubricating oil channel 374.

[0121] With this design, lubricating oil can enter the pin body 371 from the lubricating oil inlet 375, and flow to the lubricating oil receiving groove 376 through the lubricating oil channel 374, which ensures the lubrication of the pin body 371, reduces the wear of the pin body 371, and extends the service life of the pin 371.

[0122] According to one embodiment of the present invention, two lubricating oil receiving grooves 376 are arranged opposite each other.

[0123] This design further improves the lubrication of the pin body 31.

[0124] According to one embodiment of the present invention, the first mounting base 320 is detachably provided with a support rod 380, and the support rod 380 is rotatably connected to the first mounting base 320.

[0125] With this design, the support rod 380 can provide auxiliary support for the cargo box 310 when it tilts to the side, reducing the pressure of the cargo box on the first hydraulic cylinder 340; the detachable nature of the support rod 380 and the first mounting base 320 ensures that the support rod 380 can provide support when the cargo box 310 is tilted in both directions.

[0126] Example 3

[0127] like Figures 15-20As shown, Example 3 is based on Example 1, with the following differences:

[0128] According to one embodiment of the present invention, it further includes a mounting frame 110 fixedly connected to the vehicle body 100 and a support leg assembly 700 connected to the mounting frame 110. The two sets of support leg assemblies 700 are respectively disposed on both sides of the vehicle body 100. The support leg assembly 700 includes a support leg body 710, which has two working positions. In the first working position, the support leg body 710 is adjacent to the mounting frame 110 and is in a retracted state. In the second working position, the support leg body 710 is far away from the mounting frame 110 and is in a supporting state.

[0129] With this design, when the tracked transporter is in operation, the outrigger body 710 can extend to both sides of the vehicle body 100 and play a supporting role. Compared with the outrigger body 710 directly supporting the vehicle body 100 by sticking close to it, the above-described embodiment provides more stable support for the vehicle body 100 and is less prone to tipping over.

[0130] According to one embodiment of the present invention, the support leg assembly 700 further includes a mounting plate 730, the support leg body 710 is connected to the mounting plate 730, and a second driving assembly for driving the mounting plate 730 to slide is provided between the mounting plate 730 and the mounting frame 110.

[0131] This design enables the outrigger body 710 to move away from the vehicle body 100.

[0132] According to one embodiment of the present invention, the outrigger assembly 700 further includes a slide cylinder 740 slidably disposed within the mounting frame 110, and the mounting plate 730 is fixedly disposed at the end of the slide cylinder 740; the second drive assembly includes an eighth hydraulic cylinder 750, the cylinder body of the eighth hydraulic cylinder 750 is fixedly connected to the mounting frame 110, the piston rod of the eighth hydraulic cylinder 750 is fixedly connected to the slide cylinder 740, and the extension and retraction direction of the piston rod of the eighth hydraulic cylinder 750 is horizontally arranged.

[0133] According to one embodiment of the present invention, the outrigger assembly 700 further includes a seventh hydraulic cylinder 720 and a rotating plate 760. The cylinder body of the seventh hydraulic cylinder 720 is fixedly connected to the rotating plate 760, and the piston rod of the seventh hydraulic cylinder 720 is fixedly connected to the outrigger body 710. The rotating plate 760 is rotatably connected to the mounting plate 730. The rotation axis of the rotating plate 760 is horizontally oriented, and a locking component for locking the rotating plate 760 in a fixed position is provided between the rotating plate 760 and the mounting plate 730.

[0134] With this design, the rotation setting of the outrigger body 710 can ensure that the outrigger body 710 is farther away from the ground when not in use, reducing the interference of the outrigger body 710 on the tracked transport vehicle during its movement (such as accidental collision between the outrigger body 710 and ground protrusions).

[0135] According to one embodiment of the present invention, the locking component includes a locking pin 771 and a limiting component. The mounting plate 730 is provided with a locking hole 731 that engages with the locking pin 771. The limiting component is used to limit the locking pin 771 within the locking hole 731.

[0136] Through this design, the locking pin 771 and the locking hole 731 cooperate to limit the movement and achieve the purpose of locking the rotating plate 760 in the current position.

[0137] According to one embodiment of the present invention, the locking assembly further includes a housing 772 fixedly connected to the rotating plate 760. The housing 772 is provided with a slide groove 773 that is slidably connected to the locking pin 771. The limiting assembly includes a compression spring 774 disposed in the slide groove 773. The two ends of the compression spring 774 abut against the bottom of the slide groove 773 and the protruding ring of the locking pin 771, respectively.

[0138] With this design, in a natural state without external force, due to the elastic force of the compression spring 774, the locking pin 771 protrudes out of the outer shell 772 and is limited to the locking hole 731.

[0139] According to one embodiment of the present invention, a separation component is provided between the locking pin 771 and the outer casing 772 to facilitate the separation of the locking pin 771 from the locking hole 731.

[0140] This design achieves the separation of the locking pin 771 from the locking hole 731, allowing the rotating plate 760 to rotate.

[0141] According to one embodiment of the present invention, the separation component includes a handle 780 fixedly connected to the locking pin 771. A matching inclined surface 781 is provided between the handle 780 and the housing 772. The length of the projection of the inclined surface 781 on the horizontal plane is not less than the depth of the locking pin 771 located in the locking hole 731.

[0142] With this design, under the action of the inclined surface 781, the rotation of the handle 780 causes it to move outward in a horizontal position, thereby driving the locking pin 771 to move outward, and the locking pin 771 separates from the locking hole 731.

[0143] According to one embodiment of the present invention, the end of the inclined surface 781 is provided with a vertical plane 782 that abuts and engages with it.

[0144] With this design, when the locking pin 771 is separated from the locking hole 731, the two vertical planes 782 are in face-to-face contact and abut against each other. Without external force, the handle 780 can remain in the current position, making it convenient for the operator to rotate the outrigger body 710.

[0145] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
