Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The purpose of this invention is to provide a rail transport equipment for forest and mountainous areas, which improves the load-bearing capacity, can adjust the center of gravity of the goods, and ensures the stability of transportation.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 5As shown: This embodiment provides a rail transport equipment for forest and mountainous areas, used for transporting power transmission line projects. It includes an MCU, a transport track, a tractor 2, and several loading vehicles 3. The tractor 2 and the loading vehicles 3 are all mounted on the transport track. A track support 1 is installed below the transport track. The track support 1 can have various support structures. The tractor 2 provides power. The tractor 2 and the loading vehicles 3 are connected by a traction ring. Adjacent loading vehicles 3 are hinged. Each loading vehicle 3 includes a loading compartment 6, a cargo plate 7, and a pressure sensor. The cargo plate 7 carries materials such as tower materials 9. The pressure sensor is located... On the cargo platform 7, the cargo is in direct contact with the pressure sensor. When the cargo platform 7 is horizontal, the pressure value detected by the pressure sensor is equal to the weight of the cargo. When the cargo platform 7 is tilted, the pressure value detected by the pressure sensor is not equal to the weight of the cargo. By comparing the pressure value detected by the pressure sensor with the weight of the cargo, the change in the center of gravity is sensed. An adjustment structure is provided between the loading compartment 6 and the cargo platform 7. The pressure sensor transmits the detected pressure value to the MCU. When a shift in the center of gravity is detected, the MCU controls the adjustment structure to keep the cargo platform 7 horizontal, ensuring that the center of gravity always falls on the transport track. This embodiment adjusts the center of gravity of the cargo 9 on the cargo platform 7 through the pressure sensor, MCU, and adjustment structure, providing sufficient stability for the transport of heavy railcars and is suitable for complex terrains and environments.

[0031] Specifically, in this embodiment, the transport track includes a central track 4 and two side track rails 5 arranged in parallel. The central track 4 includes several sections of central track assemblies that are connected in sequence and can be disassembled. The side track rails 5 include several sections of side track assemblies that are connected in sequence and can be disassembled. The two side track rails 5 are located on both sides of the central track 4. The side track rails 5 are made of hollow square steel pipes and serve as the traveling plane of the wheels. A rack is welded to the lower surface of the central track 4, and the rack is provided with meshing teeth for engaging with the tractor 2 and the loader 3.

[0032] The transport track in this embodiment adopts a three-track design, which has better stability than a single track, and the center of gravity of the loading vehicle 3 and the cargo 9 is less likely to shift. Compared with a two-track track, the central track 4 in this embodiment allows the tractor 2, the loading vehicle 3 and the transport track to mesh, preventing slippage, and can distribute the weight on the three tracks, thus bearing greater weight. The central track 4 and the side track 5 adopt a multi-segment, detachable design, which is suitable for complex terrain and can be recycled.

[0033] In this embodiment, the tractor 2 includes a tractor carriage, within which a drive structure is installed. The power output end of the drive structure is equipped with a power gear, which meshes with the meshing teeth of the central rail 4. The bottom of the tractor carriage is equipped with a first traveling wheel and a second traveling wheel. The first traveling wheel is located on a side rail 5, and the second traveling wheel is also located on the side rail 5. The tractor 2 is also equipped with an electromagnetic brake, which can brake promptly when a stop is required.

[0034] In this embodiment, the tractor carriage is also equipped with a range extender and a battery. The range extender is electrically connected to the battery and charges the battery. The battery is electrically connected to the drive structure and provides power to the drive structure.

[0035] In this embodiment, the loading vehicle 3 also includes a meshing gear, a third traveling wheel and a fourth traveling wheel. The meshing gear, the third traveling wheel and the fourth traveling wheel are rotatably connected to the loading vehicle compartment 6. The meshing gear meshes with the meshing teeth of the central rail 4. The third traveling wheel is located on the side rail 5 of the rail, and the fourth traveling wheel is located on the side rail 5 of the rail.

[0036] In this embodiment, the adjustment structure includes two hydraulic cylinders 8, which are symmetrically arranged. The MCU controls the action of each hydraulic cylinder 8 based on the signal from the pressure sensor. When the loading vehicle 3 climbs a slope, the hydraulic cylinder 8 located at the rear end extends, keeping the cargo plate 7 level.

[0037] In this embodiment, the forest and mountain rail transport equipment is equipped with a pressure sensor on the cargo plate 7. When the slope of the transport track changes, the pressure detected by the pressure sensor will also change, and the center of gravity of the cargo will also change accordingly. The pressure value will be sent to the built-in MCU of the loading carriage 6. The MCU controls the hydraulic cylinder 8 to adjust the angle of the cargo plate 7 of the loading carriage 3 to ensure the stability of the center of gravity of the cargo 9.

[0038] Specifically, such as Figure 4 As shown, when the loading vehicle 3 is going downhill, the pressure detected by the pressure sensor will change. The value is the component F' of the cargo weight G in the direction perpendicular to the loading vehicle 3. G and F' are not equal. When this change is detected, the pressure sensor feeds back the signal to the MCU. The MCU controls the hydraulic cylinder 8 to change the angle of the cargo plate 7, such as... Figure 5 As shown, the hydraulic cylinder 8 at the front end extends and the hydraulic cylinder 8 at the rear end retracts. After the angle of the cargo plate 7 is changed by the hydraulic cylinder 8, the force F sensed by the pressure sensor is equal to the weight G of the cargo, thereby maintaining the stability of the cargo's center of gravity.

[0039] This embodiment utilizes a pressure sensor in conjunction with a hydraulic cylinder 8 to adjust the center of gravity of the cargo 9, ensuring stable transportation and effectively preventing dangerous phenomena such as tipping over due to changes in the cargo's center of gravity. The transport track in this embodiment employs a three-rail design, with the traveling wheels positioned on the side rails 5 and a rack welded to the central rail 4. Power from the tractor 2 is transmitted to a power gear, which meshes with the rack on the central rail 4 to provide forward propulsion and enable movement. This embodiment maintains a stable center of gravity even in complex mountainous terrain. Even if the tractor 2 stops midway, the meshing of the power gear, meshing gear, and rack prevents slippage, resulting in better balance and enhanced load-bearing capacity compared to existing technologies. This embodiment uses multiple detachable transport tracks and a tractor 2 towing multiple loading vehicles 3, effectively handling terrain requiring turns. The detachable transport tracks can be reused. In the transportation of materials for power transmission line projects in forested mountainous areas, the forested mountainous area rail transport equipment of this embodiment is easy to construct, low in cost, and does not damage the surrounding ecosystem.

[0040] To achieve self-loading and unloading of goods, such as Figure 6As shown, this embodiment also includes two loading and unloading structures 21, which are respectively set at the beginning and end of the transport track. Each loading and unloading structure 21 includes a rotating platform 11, a base 10, a connecting rod structure, a first telescopic structure 12, a second telescopic structure 13, and a hook 14. The base 10 is set on the rotating platform 11, which is located on the ground. The base 10 and the rotating platform 11 are rotatably connected, allowing the base 10 to rotate around an axis perpendicular to the ground. The connecting rod structure includes a first connecting rod 15, a second connecting rod 16, a third connecting rod 17, a fourth connecting rod 18, and a fifth connecting rod 19. The base 10, the first connecting rod 15, the second connecting rod 16, the third connecting rod 17, the fourth connecting rod 18, and the fifth connecting rod 19 are all made of low-alloy steel Q345. The third connecting rod 17, the fourth connecting rod 18, and the fifth connecting rod 19 are connected end-to-end to form a triangular structure. One end of the first connecting rod 15 is connected to the base 10. The first link 15 is hinged to one end of the third link 17, one end of the second link 16 is hinged to the base 10, and the other end of the second link 16 is hinged to the other end of the third link 17. The distance between the two hinge points on the first link 15 and the two hinge points on the second link 16 are equal. The distance between the two hinge points on the base 10 is equal to the distance between the two hinge points on the third link 17. The first link 15, the second link 16, the third link 17 and the base 10 form a parallel four-bar linkage. The hook 14 is set at one end of the lifting arm 20. The other end of the lifting arm 20 is hinged to the fifth link 19. One end of the first telescopic structure 12 is connected to the base 10, and the other end of the first telescopic structure 12 is hinged to the middle of the first link 15. One end of the second telescopic structure 13 is connected to the fifth link 19, and the other end of the second telescopic structure 13 is hinged to the middle of the lifting arm 20.

[0041] In this embodiment, all kinematic pairs are lower pairs with surface contact, resulting in low pressure on the mechanism, easy lubrication, minimal wear between connecting parts, high load-bearing capacity, and simple component shapes. The contact between components is maintained by the geometric constraints of the connecting parts, ensuring reliable operation. Furthermore, the parallel four-bar linkage can achieve transformations between various motion forms, and multiple motion trajectories can be achieved using the linkages. Under normal operating conditions without interference, the parallel four-bar linkage will not exceed its dead point position, exhibiting a stable motion trajectory and good load-bearing capacity, making it ideal for maintaining horizontal loading and unloading operations.

[0042] In this embodiment, each hinge joint is achieved by using pins, which can bear a larger radial load, making it more suitable for low-speed heavy-load conditions. It is also lower in cost, easier to maintain, more reliable in operation, and easier to disassemble.

[0043] In this embodiment, the connection points and loading / unloading ends are simulated using virtual prototyping technology to ensure that the strength meets the requirements, and a hydraulic transmission method that combines adjustment and layout flexibility with high power density is selected.

[0044] In this embodiment, the first telescopic structure 12 includes two cylinders, and the second telescopic structure 13 includes two hydraulic cylinders. Each second telescopic structure 13 is equipped with a displacement sensor, preferably a rope displacement sensor. This embodiment employs an open-loop electro-hydraulic proportional control system. A communication radio is used to receive external control signals and transmit them to the controller. The communication radio is connected to the controller, and the controller controls the CAN bus valve to adjust the extension and retraction of the second telescopic structure 13. Figure 7 As shown, specifically: each of the second telescopic structures 13 is connected to a control valve, the oil tank is connected to the control valve and the second telescopic structure 13 respectively, the second telescopic structure 13, the displacement sensor, the control valve and the communication radio are all electrically connected to the controller, the displacement sensor collects the displacement data of the corresponding second telescopic structure 13, and the data collected by the two displacement sensors are transmitted to the controller for comparison, which can determine the consistency of the movement of the two second telescopic structures 13, and determine whether there is a large sway of the structure by the fluctuation of the data.

[0045] When the hook 14 lifts the goods, the first telescopic structure 12 extends to achieve gravity balance. When the hook 14 separates from the goods, the first telescopic structure 12 retracts. In this embodiment, the first telescopic structure 12 maintains the balance of the device. A rotating platform 11 is provided under the base 10 of this embodiment, which facilitates the free rotation of the device and allows for flexible lifting and lowering of objects. The parallel four-bar linkage is used to maintain the stability of the motion trajectory and good load-bearing capacity to complete the horizontal loading and unloading operation. The device is installed on the ground at the beginning and end of the transport track to complete the lifting of transported goods, which are then transported via the transport track. This solves the problem that current rail transport equipment still requires a crane to complete the lifting work.

[0046] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
