[0001] This utility model relates to the field of transportation equipment technology, specifically a device suitable for transporting goods on mountain roads. Background Technology
[0002] Mountainous areas have complex terrain and inconvenient transportation, making it difficult for ordinary trucks to carry out material transportation tasks. At the same time, due to the harsh environment, many mountain roads are poorly constructed, with steep slopes and many bends, making it difficult for many vehicles to pass. Therefore, transporting materials in mountainous areas is a very complex and challenging problem.
[0003] Currently, when transporting supplies in mountainous areas, traditional methods such as handcarts, stretchers, or carrying have the following shortcomings due to the complex terrain, narrow roads, and steep slopes:
[0004] 1. Manual carrying is a heavy burden, and carrying it for a long time can easily cause fatigue and injury.
[0005] 2. Ordinary wheeled handcarts have poor adaptability and are difficult to move smoothly on rugged mountain roads, and are prone to tipping over or getting stuck.
[0006] 3. Some of the transport equipment is bulky and inconvenient to carry, making it unable to meet the needs of transporting goods on mountain trails. Summary of the Invention
[0007] The purpose of this invention is to provide a device suitable for transporting goods on mountain roads, so as to solve the problems mentioned in the background art.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please refer to Figure 1. In this embodiment of the present invention, a device suitable for transporting goods on mountain roads includes a platform 1. A tracked chassis 2 is installed at the bottom of the platform 1. Fixed beams 3 and movable plates 4 are respectively arranged front and rear on the bottom surface of the platform 1. The fixed beams 3 are welded to the bottom of the platform 1. A front wheel frame 6 is hinged to the rear end of the fixed beams 3. A front wheel 7 is installed at the bottom of the front wheel frame 6. A first telescopic cylinder 8 is provided between the front wheel frame 6 and the front end of the fixed beams 3. The two ends of the first telescopic cylinder 8 are respectively hinged to the front wheel frame 6 and the fixed beams 3. A rotating shaft 5 is installed on the movable plate 4. The rotating shaft 5 is rotatably connected to a bearing seat at the bottom of the movable plate 4. A rear wheel frame 9 is hinged to the front end of the movable plate 4. A rear wheel 11 is installed at the bottom of the rear wheel frame 9. A second telescopic cylinder 10 is provided between the rear wheel frame 9 and the rear end of the movable plate 4. The two ends of the second telescopic cylinder 10 are respectively hinged to the rear wheel frame 9 and the movable plate 4. Extension frames 13 are movably installed on the left and right sides of the platform 1.
[0023] Please refer to Figures 1-3. Two fixed railings 15 are installed between the two extension frames 13, one in front of the other. Movable railings 14 are fitted on the fixed railings 15. The bottom of the movable railings 14 is fixedly connected to the vehicle platform 1. The cooperation between the fixed railings 14 and the movable railings 15 can protect the materials on the vehicle platform 1 in the front-to-back direction, preventing the materials from falling off the vehicle platform 1 during the handling process due to sudden stops or accelerations of the equipment.
[0024] The bottom end of the extension frame 13 is movably inserted into the insertion hole opened on the vehicle plate 1. The limiting component is located between the vehicle plate 1 and the extension frame 13 to limit the extension frame 13 from sliding on the vehicle plate 1. This design makes it easy to pull the extension frame 13 out of the vehicle plate 1, and facilitates the adjustment of the equipment handling space through the extension frame 13, thereby better meeting the handling needs of materials of different sizes.
[0025] The limiting component includes multiple bolts 16, and multiple through holes are provided on the vehicle plate 1. The extension frame 13 has the same number of threaded holes 17 as the through holes and they are one-to-one corresponding. The bolts 16 pass through the corresponding through holes and are threadedly connected to the corresponding threaded holes 17. The threaded holes 17 can realize multi-level adjustment of the extension length of the extension frame 13, so as to avoid the extension frame 13 extending too far, causing the materials to shift on the vehicle plate 1 and causing the equipment to become unstable.
[0026] Two directional handles 12 are welded to the rear of the movable plate 4. The directional handles 12 can be used by personnel to manually control the direction of movement during wheel drive. It should be noted that the tracked chassis 2 usually comes with a steering system and does not require manual control.
[0027] A control panel 18 is installed between the two directional handles 12, and the control panel 18 is electrically connected to the first telescopic cylinder 8 and the second telescopic cylinder 10. A drive motor is installed on the two rear wheels 11. The control panel 18 is electrically connected to the drive motor, the drive motor installed on the tracked chassis 2, the diesel engine or hydraulic motor, the first telescopic cylinder 8, and the second telescopic cylinder 10 to control the operation of different equipment. It should be noted that the rear wheel frame 9 maintains a certain distance from the track of the tracked chassis 2 to prevent the rear wheel frame 9 from colliding with the track during rotation. The first telescopic cylinder 8 and the second telescopic cylinder 10 are both electric push rods.
[0028] The working principle of this utility model is as follows:
[0029] When in use, first place the goods to be transported on the platform 1. The surrounding area is protected by the extension frame 13 and the fixed railing 14. When traveling on steep slopes, gravel, or muddy roads, select track drive. At this time, simply turn on the drive unit of the tracked chassis 2 by using the start switch on the control panel 18. The drive unit drives the drive wheel to rotate, thereby moving the entire equipment forward. When using on flat or gentle slope terrain, select wheel drive. At this time, first control the extension of the first telescopic cylinder 8 and the second telescopic cylinder 10 at the bottom of the platform 1 by the control panel 18. This will drive the front wheel frame 6 and the rear wheel frame 9 to rotate downwards synchronously until the front wheel 7 and the rear wheel 11 touch the ground and lift the tracked chassis 2 off the ground to a certain height. Then, start the drive motors installed on the two rear wheels 11. The drive motors drive the rear wheels 11 to rotate forward, thereby moving the equipment forward. At this time, the personnel need to hold the handle 12 to control the rotation direction of the two rear wheels 11 in order to control the direction of movement.
[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
