Abstract
Description
Technical Field
[0001] This utility model relates to the field of freight vehicles, and in particular to a freight vehicle for complex road conditions. Background Technology
[0002] Most existing freight vehicles in China are single-function vehicles. For example, flatbed trucks (with round wheels under the cargo flatbed) are only suitable for transporting goods on flat surfaces, while stair climbers (with a tracked stair-climbing structure under the cargo flatbed) are suitable for transporting goods on stairs (they can also be used on flat surfaces, but at a slower speed). Thus, the functions of existing freight vehicles are relatively limited. Some can only transport goods on flat surfaces, while others are only suitable for climbing stairs, and they cannot adapt to freight use in different environments. Utility Model Content

[0033] 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.
[0034] To achieve the above-mentioned utility model objectives, such as Figure 1-7 As shown, this utility model provides a freight vehicle for complex road conditions, including a cargo flatbed 1 and a track component 6. The track component 6 is installed on the bottom left and right sides of the cargo flatbed 1. A control box 9 is embedded in the front part of the cargo flatbed 1. The control box 9 includes a battery, a track drive motor controller, and a control switch.
[0035] In this embodiment, the track drive motor controller and the battery are electrically connected via a power source, and the track drive motor controller and the track component 6 are connected via a belt drive (not shown in the figure). When the power switch on the control switch is turned on, the battery will supply power to the track drive motor controller. At this time, the track drive motor controller will drive the track component 6 to rotate via the belt, thereby realizing the movement of the freight vehicle. At this time, the goods can be placed on the cargo platform 1, thereby realizing the transfer of goods.
[0036] As another implementation method, such as Figure 3 , 4As shown in Figure 5, the rear directional wheel 5 is installed at the bottom of the cargo flatbed 1 and located on the outer side of the track component 6. The rear directional wheel 5 and the bottom of the cargo flatbed 1 are rotatably connected through the rear wheel axle 2. The front universal wheel 7 is installed at the bottom of the cargo flatbed 1 and located in the middle of the two track components 6. The front universal wheel 7 and the bottom of the cargo flatbed 1 are rotatably connected through the front wheel axle 4. The front wheel axle 4 and the rear wheel axle 2 are connected through the connecting rod 8. An electric push rod 3 is provided at the bottom of the cargo flatbed 1. The electric push rod 3 is rotatably connected to the bottom of the cargo flatbed 1 and rotatably connected to the rear wheel axle 2.
[0037] In this embodiment, the rear axle 2 and the front axle 4 are linked by the connecting rod 8. The electric push rod 3 can be extended and retracted by control, thereby controlling the extension and retraction of the rear directional wheel 5 and the front swivel wheel 7. Thus, when the bottom surface is relatively flat, the electric push rod 3 can drive the rear directional wheel 5 and the front swivel wheel 7 to extend, so that the rear directional wheel 5 and the front swivel wheel 7 contact the bottom surface, making the entire freight vehicle move more quickly. When the ground is uneven or needs to climb stairs, the electric push rod 3 can retract the rear directional wheel 5 and the front swivel wheel 7, so that the track component 6 contacts the bottom surface, thereby enabling transportation on uneven ground or when climbing stairs, and making the transportation of the entire freight vehicle more diversified.
[0038] Specifically, it should be noted that, such as Figure 3 As shown, the tops of the rear directional wheel 5 and the front universal wheel 7 are fixedly connected to the rear wheel axle 2 and the front wheel axle 4 via a support frame. The side of the support frame is rotatably connected to the connecting rod 8 via a rotating shaft. A U-shaped frame is welded at the bottom middle position of the rear wheel axle 2. One end of the electric push rod 3 is rotatably connected to the U-shaped frame via a rotating shaft. A U-shaped frame is also welded to the bottom of the cargo platform 1. The other end of the electric push rod 3 is also rotatably connected to the U-shaped frame via a rotating shaft.
[0039] The rear axle 2 of the cargo vehicle is connected to a drive motor (not shown in the figure). The drive motor is electrically connected to the battery inside the control box 9. When the corresponding power switch on the control switch is turned on, the battery can supply power to the drive motor, so that the drive motor can drive the rear axle 2 to rotate, thereby driving the entire cargo vehicle to move.
[0040] Preferably, a pusher 10 is fixedly connected to the front end of the cargo flatbed 1 by welding. With the pusher 10, the entire cargo vehicle can also be manually driven to move, and the direction of movement of the cargo vehicle can be changed by pushing the pusher 10.
[0041] As another implementation method, such as Figure 1As shown, a front cargo fixing frame 12 is provided at the upper front end of the cargo flatbed 1, and a rear cargo fixing frame 11 is provided at the upper rear end of the cargo flatbed 1. Thus, the front cargo fixing frame 12 and the rear cargo fixing frame 11 can be used to clamp and position the cargo, thereby making the placement of the cargo more stable.
[0042] Specifically, such as Figure 7 As shown, the rear cargo fixing frame 11 includes a fixing clamp 111, a telescopic rod 112, and a positioning support frame 113. The positioning support frame 113 is fixedly installed at the upper end of the cargo flatbed 1. The telescopic rod 112 is connected to one side of the positioning support frame 113, and the fixing clamp 111 is connected to the side of the telescopic rod 112 away from the positioning support frame 113. In this way, the position of the fixing support frame 111 can be adjusted by setting the telescopic rod 112, thereby enabling the clamping and fixing of goods of different volumes.
[0043] Preferably, the telescopic rod 112 includes a telescopic inner rod, a telescopic outer rod, and a fastening nut. The telescopic inner rod is inserted into the interior of the telescopic outer rod, and the telescopic inner rod is fixedly connected to the positioning support frame 113. The telescopic outer rod is fixedly connected to the fixed clamping frame 111. The telescopic outer rod has a threaded hole, and a fastening nut is screwed into the threaded hole. The fastening nut can abut against the telescopic inner rod when screwed inward. By adjusting the relative position of the telescopic inner rod and the telescopic outer rod, and then tightening and fixing them by the fastening nut, the position of the fixed clamping frame 111 can be adjusted, thereby enabling the clamping and fixing of goods of different volumes.
[0044] It should also be noted that the front cargo fixing frame 12 and the rear cargo fixing frame 11 are set up to make the placement of the cargo more stable, not to completely prevent the cargo from tipping over. Limiting devices can also be set on both sides of the cargo platform 1 to clamp the sides of the cargo, thereby making the placement of the cargo more stable.
[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
