[0018] 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.

[0019] like Figure 1-5 As shown, the tracked transport vehicle of this utility model includes a vehicle body 1, a cargo box 2 connected to the vehicle body 1, a power source assembly 3, and track wheels 4. The vehicle body 1 is fixedly equipped with a lifting bracket 5, and the cargo box 2 is connected to the lifting bracket 5 and positioned above the lifting bracket 5. The power source assembly 3 is positioned between the lifting bracket 5 and the vehicle body 1. The track wheels 4 are used to drive the vehicle body 1 to move, and the power source assembly 3 is used to provide power to the track wheels 4.

[0020] With this design, the tracked transport vehicle has a wide range of applications: the vehicle body has only a cargo box on top and no other obstructing structures, which can place and transport extra-long goods such as pipes, solving the problem that some existing tracked transport vehicles cannot transport extra-long items due to structural limitations such as the shell.

[0021] Reasonable spatial layout: By setting up a raised support, the power source components are cleverly arranged between the raised support and the vehicle body, which not only provides installation space for the power source components, but also avoids the power source components occupying the load-bearing space of the carriage, so that the carriage can focus on the placement and transportation of goods. The overall structural design is compact and practical.

[0022] According to one embodiment of the present invention, the vehicle body 1 includes a main beam 11 and a baffle plate 12 fixedly connected to the main beam 11. The baffle plate 12 is disposed above the track wheel 4, and a mounting plate 13 is fixedly disposed at the rear end of the baffle plate 12.

[0023] Through this design, the main beam, shielding plate, and mounting plate provide the main load-bearing structure for the fixed installation of the raised support. At the same time, the main beam, as the core load-bearing structure of the vehicle body, provides a stable support foundation for the entire vehicle body and the components above it, ensuring the stability of the overall structure. The shielding plate can protect the track wheels, reducing the chance of the track wheels being hit by debris such as gravel and mud during transportation. The mounting plate is fixed to the rear end of the shielding plate, which can prevent gravel from flying backward.

[0024] According to one embodiment of the present invention, the lifting bracket 5 includes a support rod 51 disposed above the two track wheels 4 and a connecting rod 52 fixedly connected between the two support rods 51. The connecting rod 52 is fixedly connected to the main beam 11 through a support column 53. The support rods 51 and the connecting rod 52 cooperate to support the carriage 2.

[0025] This design provides stable support for the carriage: the support rods are positioned above the two track wheels and are fixedly connected to the connecting rods to form a frame structure. The two work together to provide stable support for the carriage, ensuring that the carriage does not sway when carrying goods and guaranteeing the stability of the transportation process.

[0026] Optimized spatial layout: The connecting rod and the main beam are fixedly connected by the support column. This connection method not only firmly installs the lifting bracket on the vehicle body, but also creates a certain space between the lifting bracket and the vehicle body, providing a reasonable position for the placement of the power source components, avoiding the power source components occupying the space of the carriage, and allowing the carriage to focus on carrying the cargo.

[0027] According to one embodiment of the present invention, the carriage 2 includes a frame 21, a bottom plate 22 fixedly connected to the frame 21, and a side plate 23 rotatably connected to the frame 21, wherein the rotation axis of the side plate 23 is horizontally arranged.

[0028] Stable and reliable structure: The frame, as the basic support structure of the carriage, is fixedly connected to the floor plate to form a stable load-bearing frame, providing a solid foundation for placing goods and ensuring that the goods are not easily deformed due to their weight during transportation.

[0029] Convenient loading and unloading: The side panels are rotatably connected to the frame, allowing them to open around a horizontal axis. When loading or unloading is required, the side panels can be flipped open to increase the loading and unloading opening, making it easier for personnel or equipment to put goods into or take them out of the carriage. This is especially effective in improving loading and unloading efficiency for large or irregularly shaped goods.

[0030] Adaptable to various cargo transportation: This structure not only ensures the load-bearing capacity of the carriage, but also enhances the flexibility of use through the rotatable side panels. It can be well adapted to both long cargo such as pipes and conventional materials such as anchor bolts and anchor nets, further expanding the application range of tracked transport vehicles.

[0031] According to one embodiment of the present invention, the carriage 2 is configured to tilt in both directions, and the axis of rotation of the carriage 2 is parallel to the length direction of the vehicle body 1.

[0032] High and flexible unloading efficiency: The bidirectional tilting design allows the cargo compartment to tilt to both sides of the vehicle body, and the cargo can be unloaded to one side according to the actual situation, which greatly improves the convenience and efficiency of unloading.

[0033] Adaptable to various operating scenarios: In different operating environments such as underground roadways and narrow working faces, the vehicle can be tilted to the left or right to unload according to the on-site space conditions, avoiding the problem of being unable to unload smoothly due to limited space on one side, thus enhancing the applicability of the transport vehicle in complex environments.

[0034] According to one embodiment of the present invention, a first rotating shaft 24 is fixedly provided on the frame 21 or the base plate 22, and a hydraulic cylinder 6 is fixedly provided on the vehicle body 1 or the connecting rod 52, wherein the piston rod of the hydraulic cylinder 6 is rotatably connected to the first rotating shaft 24.

[0035] Achieving stable tilting of the cargo compartment: The hydraulic cylinder, as the power component, has its piston rod rotatably connected to the first rotating shaft, providing a reliable driving force for tilting the cargo compartment. When the hydraulic cylinder extends or retracts, it can drive the cargo compartment to tilt smoothly, ensuring a smooth and controllable unloading process.

[0036] According to one embodiment of the present invention, the end of the support rod 51 is provided with a pivot hole 511, the frame 21 is fixedly provided with a pivot plate 25, the pivot plate 25 is provided with a through hole 251, the through hole 251 and the pivot hole 511 are arranged coaxially; it also includes a pin 7 passing through the through hole 251 and the pivot hole 511, the pin 7 being detachably connected to the pivot plate 25.

[0037] Achieving a reliable connection between the carriage and the raised support: The through hole and the pivot hole are set on the same axis, and the pin passes through them, which can firmly connect the carriage and the raised support, ensuring that the carriage is not easy to detach from the raised support during the loading and transportation of goods, thus ensuring structural stability.

[0038] Providing a rotating basis for tipping the carriage: The pin shaft, as the core component of the rotating shaft, allows the carriage to rotate flexibly around it. In conjunction with power components such as hydraulic cylinders, it realizes the bidirectional tipping function of the carriage to meet unloading needs. When tipping is required, simply pull out the pin shaft on one side, the hydraulic cylinder extends, and the carriage can rotate around the pin shaft on the other side.

[0039] According to one embodiment of the present invention, a reinforcing rib 531 is fixedly provided between the support column 53 and the baffle plate 12.

[0040] Enhanced structural stability and load-bearing capacity: The reinforcing ribs effectively connect the support columns and the baffles, forming a more stable stress structure. They can disperse the pressure transmitted from the support columns to the baffles, thereby extending the service life of related vehicle components and ensuring the overall structural reliability of the transport vehicle under heavy loads or complex working conditions.

[0041] According to one embodiment of the present invention, the vehicle body 1 is further provided with a boom 8, the width of which is smaller than the width of the carriage 2.

[0042] Expanding functionality: The boom can be used to assist in loading and unloading goods, such as lifting heavy or difficult-to-handle materials like anchor bolts and anchor nets, reducing labor intensity and improving work efficiency. This allows the handling vehicle to not only have transportation functions but also to undertake certain lifting operations, enhancing the overall practicality of the equipment.

[0043] To avoid interference: Since the width of the crane boom is smaller than the width of the carriage, when loading extra-long goods into the carriage, the goods can be placed close to the crane boom, which can avoid spatial interference with the goods and ensure smooth placement and transportation of the goods.

[0044] 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.
