DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The self-moving rail flatbed vehicle of the utility model runs on the track 6 used in the existing rail transportation, and the track 6 can be a railway track, a subway track or a light rail track.

[0025] like Figure 1 and 2As shown, a self-propelled rail flatbed vehicle includes a vehicle body, the vehicle body includes a load-bearing plate 1 and a power mechanism for driving the load-bearing plate 1 to move, the power mechanism includes a plurality of running wheels 4 and a driving motor 18 for driving some of the running wheels 4 to rotate, at least two swing arms 14 are rotatably connected below the load-bearing plate 1, the swing arms 14 are fixedly connected to friction blocks 8, and during the rotation of the swing arms 14, the friction blocks 8 can be pressed tightly against the lower edge 7 of the track 6, the two swing arms 14 are also commonly connected to an electric push rod 13 for driving the swing arms 14 to rotate, a battery box 20 is fixedly arranged above the load-bearing plate 1, and a power battery pack 21 for supplying power to the driving motor 18 and the electric push rod 13 is detachably arranged in the battery box 20.

[0026] When transporting articles, the utility model first places the articles on the carrying plate 1, and then utilizes the driving motor 18 to drive the running wheel 4 to rotate. During the rotation of the running wheel 4, it moves along the track 6, thereby driving the vehicle body to move as a whole, and realizing the transportation of the articles; when braking is needed, the electric push rod 13 is utilized to drive the swing rod 14 to rotate until the friction block 8 is pressed against the lower edge 7 of the track, thereby utilizing the friction force between the friction block 8 and the lower edge 7 of the track to lock the vehicle body, and because the friction block 8 is pressed against the lower edge 7 of the track, the vehicle body can be limited to prevent the vehicle body from tilting or even falling on the inclined track 6, thereby realizing the protection of the vehicle body and the articles; when the power battery pack 21 is insufficient in power, the power battery pack 21 can be removed for charging, and a new power battery pack 21 can be replaced, thereby ensuring that the articles can be transported normally.

[0027] The utility model can utilize the driving motor 18 to drive the vehicle body to move, and does not need to be towed by a traction vehicle, so it is more convenient to use. When braking is needed, the utility model can utilize the cooperation of the electric push rod 13, the swing rod 14 and the friction block 8 to achieve deceleration and braking. After braking is completed, the vehicle body can also be protected to prevent the vehicle body from tilting or even tipping over on the inclined track 6.

[0028] The specific structure of the power mechanism is as follows: four vertically arranged mounting plates 2 are fixedly connected to the lower surface of the carrier plate 1, two mounting plates 2 form a group, and the two mounting plates 2 in the same group are rotatably connected to the wheel axle 3, two running wheels 4 are fixedly sleeved on the wheel axle 3, one of the wheel axles 3 is fixedly sleeved with a driven gear 9, and the driving motor 18 is drivingly connected to the driving gear 10 meshing with the driven gear 9. That is, the power mechanism includes four running wheels 4, and every two running wheels 4 are arranged on one wheel axle 3. When the driving motor 18 is actuated, the driving gear 10 is driven to rotate, and then the driving gear 10 drives the driven gear 9 to rotate. During the rotation of the driven gear 9, the wheel axle 3 and the running wheel 4 are driven to rotate synchronously, thereby achieving the effect of driving the vehicle body to move.

[0029] In order to ensure that the vehicle body can move smoothly on the track 6 and avoid derailment, the running wheel 4 is coaxially fixedly connected with an annular limit plate 5, and the limit plate 5 is attached to the inner wall of the track 6.

[0030] like Figure 3 As shown, the specific structure of the mounting plate 27 is as follows: the two mounting plates 2 in the same group are both provided with a center hole 25 and a mounting hole 27, the wheel axle 3 is passed through the center hole 25 and connected to the mounting plate 2 through a bearing 26, a rotating shaft 15 is rotatably passed through the mounting hole 27, two swinging rods 14 are provided, and the two swinging rods 14 are correspondingly fixedly connected to the rotating shaft 15. In order to ensure that the rotating shaft 15 can rotate smoothly, the rotating shaft 15 can also be connected to the mounting plate 2 through a bearing 26.

[0031] The specific method of the electric push rod 13 driving the swing rod 14 is as follows: the electric push rod 13 is driven and connected to the accommodating tube 12, and the two swing rods 14 extend into the accommodating tube 12, and the inner diameter of the accommodating tube 12 is larger than the diameter of the swing rod 14. During the operation of the electric push rod 13, the accommodating tube 12 is driven to move, and then the accommodating tube 12 drives the end of the swing rod 14 extending into the accommodating tube 12 to rotate, so that the swing rod 14 as a whole rotates around the axis of the rotating shaft 15. During the process, the other end of the swing rod 14 also rotates, thereby driving the friction block 8 to rotate synchronously, so that the friction block 8 is pressed against the lower edge 7 of the track or separated from the lower edge 7 of the track. Specifically, Figure 1 and 2 As shown, in Figure 1 In the process, the friction block 8 is pressed against the lower edge 7 of the track, and the whole is in a braking state. Figure 2 By making the inner diameter of the housing tube 12 larger than the outer diameter of the swing rod 14, the end of the swing rod 14 extending into the housing tube 12 has a certain amount of space for movement, thereby changing the contact state with the housing tube 12 during the rotation process, and further changing the contact state between the friction block 8 and the lower edge 7 of the track.

[0032] Considering that when the carrying plate 1 carries items, some items are large in size and heavy in weight, if they are directly pressed on the battery box 20, the battery box 20 may be damaged and deformed, and then the power battery pack 21 may be damaged. In order to protect the battery box 20 and the power battery pack 21, a protective box 19 is fixedly arranged on the carrying plate 1, and the battery box 20 is fixedly arranged in the protective box 19. A certain gap can be left between the protective box 19 and the battery box 20 to prevent the vibration from being transmitted to the power battery pack 21 when the items vibrate, causing poor contact or damage to the power battery pack 21. The gap can also be further filled with materials such as sponges with shock absorption capabilities to further protect the battery box 20 and the power battery pack 21.

[0033] In order to more effectively protect the power battery pack 21 and prevent corrosion factors such as water vapor from entering the battery box 20 and causing damage to the power battery pack 21, the power battery pack 21 is fixedly connected to a cover plate 23, which can close the battery box 20. A sealing gasket 22 is fixedly arranged on the inner side of the cover plate 23, and a pull ring 24 is fixedly connected to the outer side of the cover plate 23. The sealing gasket 22 can be made of rubber material to improve the sealing performance of the battery box 20. The pull ring 24 can easily remove the cover plate 23. Because the cover plate 23 and the power battery pack 21 are fixedly connected, the power battery pack 21 can also be easily removed and replaced.

[0034] like Figure 4 and 5 As shown, in order to prevent the power battery pack 21 from being loosened due to the vibration of the vehicle body during movement, at least one locking mechanism is fixedly connected to the outer wall of the battery box 20, and the locking mechanism is used to lock the cover plate 23. The locking mechanism includes a base plate 28 fixedly connected to the battery box 20, and the base plate 28 is fixedly connected to two mutually parallel side plates 30, and a movable groove 34 is opened on the side plate 30, and a movable shaft 33 is passed through the two movable grooves 34. A spring 35 is connected between the movable shaft 33 and the base plate 28, and the movable shaft 33 is also rotatably connected to the connecting rod 31. At least one hook 32 is fixedly connected to the peripheral side wall of the cover plate 23, and a hanging hole matching the hook 32 is opened on the cover plate 23. After the power battery pack 21 is placed into the battery box 20 and the battery box 20 is closed with the cover 23, the cover 23 is locked with a locking mechanism. Specifically, the connecting rod 31 is first pulled to move, during which the electric movable shaft 33 of the connecting rod 31 moves synchronously in the movable groove 34 and stretches the spring 35. After the connecting rod 31 moves to a certain position, the connecting rod 31 is rotated to rotate around the axis of the movable shaft 33, so as to be staggered with the hook 32, and then the hook 32 is correspondingly inserted into the hanging hole, so that the connecting rod 31 is hung on the hook, and finally the connecting rod 31 is released. Under the rebound action of the spring 35, the spring 35 can pull the movable shaft 33 and the connecting rod 31 to move synchronously in the direction of the substrate 28, and the connecting rod 31 pulls the hook 32 and the cover 23 to move synchronously in the direction of the battery box 20 until the cover 23 is tightly attached to the battery box 20, thereby ensuring that the battery box 20 can be closed.

[0035] A protective plate 29 is also fixedly connected between the two side plates 30. A storage space is enclosed between the protective plate 29, the two side plates 30, the base plate 28 and the battery box 20. The spring 35, the movable shaft 33 and a part of the connecting rod 31 are all located in the storage space, thereby protecting the spring 35, the movable shaft 33 and a part of the connecting rod 31. Similarly, in order to protect the drive motor 18, a motor bracket 11 is fixedly connected to the lower surface of the carrier plate 1. The motor bracket 11 includes a support plate for supporting the drive motor 18. The support plate is fixedly connected to the carrier plate 1 through two mutually parallel baffles, and the drive motor 18 is located between the two baffles.

[0036] In order to facilitate the movement of the staff with the vehicle, two vertical poles 16 are vertically fixedly arranged on the carrying plate 1 , and a handrail 17 is fixedly connected between the two vertical poles 16 .

[0037] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
