Description

Technical Field

[0001] This utility model relates to the field of transportation technology in hilly and mountainous areas, specifically to a transportation vehicle for use in hilly and mountainous environments. Background Technology

[0002] In power transmission line construction, the main components that need to be transported include insulators and conductors. Insulators support or suspend conductors, insulating them from the towers and ensuring insulation between the conductors and the ground, as well as insulation between the three phases. When transportation needs to cross rivers, deep valleys, or when towers are located in swamps, steep slopes, high mountains, snow-capped mountains, or environmentally sensitive areas, traditional human and animal-powered transportation is very difficult, and may even be impossible. Material transportation in hilly and mountainous areas typically involves road transport and cableway transport. Tracked vehicles have a greater advantage in hilly and mountainous areas. The large contact area between the tracks and the ground provides greater mechanical traction to cope with rugged mountain roads; moreover, tracks can easily cross obstacles, especially in scenarios involving climbing slopes and crossing ditches. Insulators are relatively fragile and easily damaged. Therefore, during transportation, it is necessary to minimize the impact of vibration on the insulators to ensure their integrity and prevent damage to the insulator's outer sheath and core, which would affect its electrical performance. Hilly and mountainous areas typically have steep mountains, treacherous mountain roads, and harsh climate conditions. Tracked vehicles are prone to bumps when transporting insulators, causing the insulators to shake and collide, resulting in damage to the insulators. Utility Model Content

[0003] The purpose of this utility model is to provide a transport vehicle for hilly and mountainous environments, which can address the problem in the prior art that insulators are easily damaged by collisions during transportation, and propose a solution to reduce the shaking amplitude of insulators during transportation and avoid damage to insulators caused by collisions.

[0004] This utility model is achieved through the following technical solution:

[0005] A transport vehicle for hilly and mountainous environments includes: a tracked vehicle; a cargo box: the cargo box is mounted on the tracked vehicle and has a first storage area and a second storage area inside the cargo box, and multiple support frames are installed sequentially from top to bottom in the first storage area; multiple rotating rollers are installed sequentially on the inner side of the support frames, and the multiple rotating rollers form a first path for transporting goods; a first limiting plate, at least one of which is installed on the support frame, and the first limiting plate divides the support frame into multiple independent third storage areas, through which goods can be transported from the first path to the third storage areas, and the size of the space in the third storage areas can be adjusted to accommodate goods of different sizes.

[0006] Furthermore, in this utility model, the above also includes a limiting component; both ends of the first limiting plate are equipped with sliders, and both ends of the support frame are provided with first mounting grooves. A guide rail that slides and engages with the slider is installed in the first mounting groove, and the slider can slide back and forth along the extension direction of the guide rail; the bottom end of the slider is provided with a second mounting groove, and the surface wall of the second mounting groove is connected to a first return spring. The free end of the first return spring is connected to a limiting member, and both sides of the bottom end of the limiting member are inclined structures; the support frame is provided with multiple limiting grooves, which are arranged along the sliding direction of the slider. The limiting member can engage with the limiting groove at a preset position to adjust the size of the space in the third storage area; the limiting component is used to prevent the limiting member from disengaging from the limiting groove.

[0007] Furthermore, in this utility model, the aforementioned limiting component includes: a first through hole, which is disposed on the slider; a second through hole, which is disposed on the limiting member, wherein when the first return spring is in its original state, the first through hole and the second through hole are aligned; and a limiting rod, which can pass through the first through hole, and the limiting rod and the second through hole are engaged by a thread.

[0008] Furthermore, in this utility model, the above also includes a second limiting plate; both sides of the first limiting plate are provided with multiple snap-fit ​​grooves along the direction of the first path, and the inner sidewalls on both sides of the cargo compartment are provided with multiple snap-fit ​​grooves along the direction of the first path, and the second limiting plate can be snapped into two oppositely arranged snap-fit ​​grooves.

[0009] Furthermore, in this utility model, a third mounting groove is provided on both sides of the second limiting plate, a second reset spring is connected to the surface wall of the third mounting groove, and a telescopic plate is connected to the free end of the second reset spring.

[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0012] During power transmission line construction, workers first package the insulators to ensure they are not damaged during transportation. Wooden crates can be used, lined with cushioning materials such as foam plastic to protect the insulators from vibration during transport. After packaging, the first crate is placed in the third storage area of ​​the support frame. During transport by the tracked vehicle, the crates inside the cargo compartment are confined within this third storage area, preventing shaking and collisions between crates in adjacent third storage areas, thus reducing the probability of collisions and maximizing the safety of the packaging.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0025] Example

[0026] Please refer to Figures 1 to 8 .

[0027] Please refer to Figure 1 and Figure 2This embodiment provides a transport vehicle for hilly and mountainous environments, including: a tracked vehicle 1; a cargo box 2: the cargo box 2 is mounted on the tracked vehicle 1, and the cargo box 2 has a first storage area 4 and a second storage area 3. Multiple support frames 5 are installed sequentially from top to bottom in the first storage area 4; multiple rotating rollers 11 are installed sequentially on the inner side of the support frames 5, forming a first path for transporting goods; and a first limiting plate 6, at least one of which is installed on the support frame 5, dividing the support frame 5 into multiple independent third storage areas 7. Goods can be transported from the first path to the third storage area 7, and the size of the space within the third storage area 7 is adjustable to accommodate goods of different sizes.

[0028] In this embodiment, the road conditions in hilly and mountainous areas may include narrow roads, numerous bends, and steep slopes. Tracked vehicles 1 have a greater advantage in transporting goods in such conditions. Tracked vehicles 1 have a large contact area with the ground, thus providing greater mechanical traction to cope with rugged mountain roads. Furthermore, the tracks can easily cross obstacles, especially in scenarios such as climbing slopes and crossing ditches. The tracked vehicle 1 is equipped with a cargo box 2, which is divided into a first storage area 4 and a second storage area 3 by a partition. The first storage area 4 can be used to store insulators; the second storage area 3 can be used to store wires, etc. Multiple support frames 5 are installed sequentially from top to bottom in the first storage area 4. Each support frame 5 can be composed of two opposing first support rods 9 and two opposing second support rods 10, which are connected sequentially to form a "U"-shaped structure. Multiple rotating rollers 11 are sequentially installed on the inner side of the support frame 5. The two ends of each rotating roller 11 are rotatably connected to the second support rod 10. These multiple rotating rollers 11 form an insulator conveying device, making it easier for the insulators to move on the support frame 5. The two ends of the first limiting plate 6 are respectively installed on the first support rod 9. The support frame 5 has N first limiting plates 6 (N≥1, and N is an integer). These N first limiting plates 6 divide the support frame 5 into N+1 independent third storage areas 7, each capable of storing insulators. The first limiting plates 6 can be installed at different positions on the support frame 5 to adjust the size of the third storage area 7, suitable for different types of insulators (suspension insulators, post insulators, tension insulators, and polymer insulators, etc.). Specifically, before transportation, the construction personnel first pack the insulators to ensure they are not damaged during transport. Wooden crates can be used for packaging, with cushioning materials such as foam plastic placed inside to prevent damage from vibration during transport. After packaging, the first box is placed in the third storage area 7 of the support frame 5. Workers can push the first box to slide it along the first path until it reaches the innermost part of the third storage area 7. Then, the second box is placed in the same third storage area 7, ensuring it is pressed tightly against another box (to prevent significant shaking during transport). This process is repeated. Once the third storage area 7 is full, the remaining boxes are placed in another third storage area 7 until it is full. Hooks can be installed on the side wall of the boxes facing the exit of the cargo compartment 2. During unloading, the boxes can be pulled out using a lever by pulling the hooks. During transport by the tracked vehicle 1, the boxes inside the cargo compartment 2 are confined within the third storage area 7, preventing shaking and collisions between boxes in adjacent third storage areas 7, reducing the probability of collisions and ensuring greater safety.

[0029] Please refer to Figure 3Furthermore, this utility model also includes a limiting component; both ends of the first limiting plate 6 are equipped with sliders 14, and both ends of the support frame 5 are provided with first mounting grooves 12. A guide rail 13 that slides and engages with the slider 14 is installed in the first mounting groove 12, and the slider 14 can slide back and forth along the extension direction of the guide rail 13; the bottom end of the slider 14 is provided with a second mounting groove 20, and the surface wall of the second mounting groove 20 is connected to a first return spring 21. The free end of the first return spring 21 is connected to a limiting member 17, and both sides of the bottom end of the limiting member 17 are inclined structures; the support frame 5 is provided with multiple limiting grooves 15, which are arranged along the sliding direction of the slider 14. The limiting member 17 can engage with the limiting groove 15 at a preset position, thereby adjusting the space size in the third storage area 7; the limiting component is used to prevent the limiting member 17 from disengaging from the limiting groove 15.

[0030] In this embodiment, the first supporting rod 9 is provided with a first mounting groove 12, which is arranged along the extension direction of the first supporting rod 9. A guide rail 13 is installed in the first mounting groove 12. The two ends of the first limiting plate 6 are slidably connected to the guide rail 13 through sliders 14. The position of the first limiting plate 6 can be adjusted along the direction of the guide rail 13, thereby adjusting the size of the third storage area 7. The first supporting rod 9 is provided with multiple limiting grooves 15 along the sliding direction of the slider 14. During the sliding process, the first limiting plate 6 can drive the limiting member 17 to slide, and the limiting member 17 can cooperate with the limiting groove 15 during the sliding process. When the limiting member 17 slides into the limiting groove 15, the first return spring 21 in a compressed state will push the limiting member 17 into the limiting groove 15. The limiting member 17 can be fixed by the limiting component, thereby limiting the size of the third storage area 7. If it is necessary to adjust the size of the third storage area 7, the limiting component can be released from the limitation of the limiting member 17. Then the first limiting plate 6 can be slid to the left or right to drive the limiting member 17 to slide (both sides of the limiting member 17 are inclined structures). The limiting member 17 abuts against the surface wall of the limiting groove 15. The side wall of the limiting groove 15 applies pressure to the inclined surface of the limiting member 17, causing the limiting member 17 to press against the first return spring 21. After the first return spring 21 is compressed, the limiting member 17 enters the second mounting groove 20, so that the slider 14 can continue to slide on the guide rail 13 to adjust the position of the first limiting plate 6, thereby adjusting the size of the space in the third storage area 7. After the first limiting plate 6 moves to the preset position, the first reset spring 21 pushes the limiting member 17 into the corresponding limiting groove 15, and then the limiting component restricts the limiting member 17, thereby fixing the position of the first limiting plate 6 and improving the stability of the goods in the third storage area 7 during cargo transportation.

[0031] Please refer to Figure 5 and Figure 6Furthermore, in this utility model, the limiting component includes: a first through hole 18, which is disposed on the slider 14; a second through hole 19, which is disposed on the limiting member 17, wherein when the first return spring 21 is in its original state, the first through hole 18 and the second through hole 19 are aligned; and a limiting rod 16, which can pass through the first through hole 18, and the limiting rod 16 and the second through hole 19 are threaded together.

[0032] In this embodiment, the slider 14 has a first through hole 18, which passes through the second mounting groove 20, and the limiting member 17 has a second through hole 19. After the first return spring 21 pushes the limiting member 17 into the preset limiting groove 15, the first return spring 21 returns to its original state, and the first through hole 18 of the slider 14 aligns with the second through hole 19 of the limiting member 17. Then, the limiting rod 16 passes through the first through hole 18 and the second through hole 19 in sequence. When the limiting rod 16 passes through the second through hole 19, it needs to be rotated to pass through the second through hole 19. After completion, the limiting member 17 can be restricted to prevent it from detaching from the preset limiting groove 15, thereby improving the stability of the goods in the third storage area 7 during cargo transportation. When it is necessary to change the size of the space in the third storage area 7, the limiting rod 16 is removed from the first through hole 18 and the second through hole 19, and then the limiting member 17 is moved to cooperate with the preset limiting groove 15. Finally, the above operation is repeated.

[0033] Please refer to Figure 7 Furthermore, this utility model also includes a second limiting plate 23; both sides of the first limiting plate 6 are provided with multiple snap-fit ​​grooves 22 along the direction of the first path, and the inner sidewalls on both sides of the cargo box 2 are provided with multiple snap-fit ​​grooves 22 along the direction of the first path, and the second limiting plate 23 can be snapped into two oppositely arranged snap-fit ​​grooves 22.

[0034] In this embodiment, when packing boxes are placed in the third storage area 7, multiple packing boxes are placed close together in sequence to reduce the space between adjacent packing boxes. After loading, the two sides of the second limiting plate 23 are inserted into the corresponding snap-fit ​​slots 22. The second limiting plate 23 can limit the packing boxes in the third storage area 7, preventing them from shaking along the first path direction during transportation and causing collisions that could damage the insulators. If the third storage area 7 is not full of packing boxes during transportation, there will be empty space. When the vehicle travels on bumpy roads, the packing boxes in the third storage area 7 may shake. The second limiting plate 23 can limit the packing boxes in the third storage area 7, solving the problem of packing box shaking.

[0035] Please refer to Figure 8Furthermore, in this utility model, a third mounting groove 24 is provided on both sides of the second limiting plate 23, a second reset spring 8 is connected to the surface wall of the third mounting groove 24, and a telescopic plate 25 is connected to the free end of the second reset spring 8.

[0036] In this embodiment, the second limiting plate 23 and the telescopic plates 25 on both sides constitute a telescopic limiting plate. The telescopic limiting plate can adjust its width to adapt to different working conditions. When adjusting the size of the third storage area 7, the first limiting plate 6 needs to be slid to a preset position. If the distance between two adjacent first limiting plates 6 decreases, the two telescopic plates 25 can be pressed against the second limiting plate 23 to reduce the overall width of the telescopic limiting plate. Then, the two telescopic plates 25 are inserted into the corresponding snap-fit ​​slots 22 respectively. At the same time, the telescopic limiting plate is also suitable for adjusting the distance between the inner side wall of the cargo compartment 2 and the first limiting plate 6.

[0037] Furthermore, in this utility model, the rotating roller 11, the first limiting plate 6, and the inner sidewall of the cargo box 2 are all provided with a buffer layer.

[0038] In this embodiment, the inner walls of the rotating roller 11, the first limiting plate 6, and the cargo box 2 can be provided with a rubber layer, which has high elasticity and flexibility and can play a buffering role when impacted, reducing damage to objects and thus reducing damage to the packaging box.

[0039] In summary, the embodiments of this utility model provide a transport vehicle for hilly and mountainous environments. Before transportation, construction personnel first pack the insulators to ensure they are not damaged during transport. Wooden crates can be used for packaging, and cushioning materials such as foam plastic can be placed inside to prevent damage from vibration during transport. After packaging, the first crate is placed in the third storage area 7 of the support frame 5. During transport by the tracked vehicle 1, the crates in the cargo box 2 are confined within the third storage area 7, preventing shaking and collisions between crates in adjacent third storage areas 7, reducing the probability of collisions, and ensuring greater safety of the crates.
