Description
Technical Field
[0001] The utility model relates to the technical field of crawler vehicles, in particular to a crawler vehicle with load protection. Background Art
[0002] Crawler vehicles refer to vehicles that use crawler tracks instead of wheels. This type of vehicle has low ground pressure, small sinking, strong adhesion and strong driving ability, so it is generally used in environments with poor road conditions. For example, when transporting food to remote rural areas or transporting wood to mountain forests, the roads are rugged and muddy, and ordinary vehicles are prone to slipping and difficult to pass. Crawler vehicles have stronger grip and can better adapt to harsh road conditions.
[0003] However, existing tracked vehicles are basically of the open-top type. When transporting bags of grain and other goods that need to be kept dry, the goods cannot be protected from rain, and there is no barrier for the part of the goods that exceeds the height of the cargo box. When going uphill, the goods on the top are easy to slide off the cargo box and cause losses.
[0004] Based on the above situation, the utility model proposes a crawler vehicle with load protection. Utility Model Content

DETAILED DESCRIPTION
[0021] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0022] Example 1
[0023] A crawler trolley with load protection, such as Figure 1-Figure 4As shown, it includes a chassis 1, a cargo box 2, a track wheel set 3, a door panel 4, a waterproof cloth 7, a cylindrical rod 8, a connecting block 9 and a long cylinder 10. The cargo box 2 is fixedly connected to the top of the chassis 1, and a pair of track wheel sets 3 are fixedly connected to the bottom of the left and right sides of the chassis 1. The track wheel sets 3 are used to provide power to the crawler vehicle. The rear side of the cargo box 2 is rotatably connected to the door panel 4, and a pair of long cylinders 10 are fixedly connected to the inside of the cargo box 2. A plurality of cylindrical rods 8 distributed longitudinally front and back are slidably connected to the top of the cargo box 2, and waterproof cloths 7 are fixedly connected between the tops of the cylindrical rods 8. The waterproof cloth 7 is used to shield the goods from rain. A connecting block 9 is fixedly connected to the inner side of the cylindrical rod 8 on the rearmost side, and the front side of the connecting block 9 is fixedly connected to the output end of the long cylinder 10. The long cylinder 10 is used to drive the cylindrical rod 8 to slide on the top of the cargo box 2.
[0024] like Figure 3 and Figure 4 As shown, it also includes support rods 801 , and a pair of support rods 801 are fixedly connected to the inner side of the cylindrical rod 8 to increase the stability of the cylindrical rod 8 .
[0025] When the tracked trolley is used to transport bagged grain and other goods that need to be kept dry, if it rains on the way, the driver can start the long cylinder 10, and the long cylinder 10 will move the connecting block 9 and the last cylindrical rod 8 backward. After the last cylindrical rod 8 stretches the folded waterproof cloth 7, it drives the second-to-last cylindrical rod 8 to move backward. After the second-to-last cylindrical rod 8 stretches the folded waterproof cloth 7, it drives the third-to-last cylindrical rod 8 to move backward, and so on, until the entire cargo box 2 is covered with the waterproof cloth 7, wherein the cylindrical rod 8 is not only used to support the waterproof cloth 7, but also to prevent the cargo from falling from both sides of the cargo box 2 when the tracked trolley is bumpy; when the cargo does not need to be covered by the waterproof cloth 7, the long cylinder 10 can also be started to drive multiple cylindrical rods 8 to move forward, and the waterproof cloth 7 is also folded up and restored to its original position.
[0026] Example 2
[0027] On the basis of Example 1, Figure 1 and Figure 5 As shown, it also includes connecting rods 11 and rounded wheels 12. A plurality of connecting rods 11 longitudinally distributed front and rear are fixedly connected to the bottom of the cargo box 2, and the middle of the connecting rods 11 is rotatably connected to the rounded wheels 12 distributed axially.
[0028] When people are loading and unloading bagged grain and other goods, the multiple rounded wheels 12 at the bottom of the cargo box 2 can reduce the friction between the goods and the cargo box 2, making it easier for workers to load and unload goods.
[0029] like Figure 1 and Figure 5 As shown, it also includes vertical long rods 13 and long cylinders 14. Multiple vertical long rods 13 distributed longitudinally front and back are fixedly connected to the left and right sides of the cargo box 2, and the middle part of the vertical long rods 13 is rotatably connected to the long cylinders 14.
[0030] When the tracked vehicle transports bags of grain and other goods, the grain bags will slide back and forth in a small range in the cargo box 2 due to the inertia of the vehicle starting and stopping. The presence of the long cylinder 14 can reduce the friction between the grain bags and the two sides of the cargo box 2 to prevent damage to the goods due to wear.
[0031] like Figure 2 As shown, it also includes a top plate 5 and supporting square rods 6. The top plate 5 is fixedly connected to the top of the cargo box 2, and the top plate 5 can be used to stack waterproof cloth 7. A plurality of axially distributed supporting square rods 6 are fixedly connected between the cargo box 2 and the chassis 1.
[0032] When the waterproof cloth 7 is not used to cover the goods, it will be folded and piled on the roof, and the top plate 5 can be used to stack the waterproof cloth 7 to prevent the waterproof cloth 7 from blocking the driver's line of sight. At the same time, due to the existence of the supporting square rod 6, the top plate 5 is more solid and can protect the driver's safety to a certain extent in sudden situations such as falling rocks.
[0033] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all modifications and equivalent structures and functions.
