[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] In the description of this application, it should be noted that the terms "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed when in use, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0031] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] The rail mobile carrying platform in this application is mainly used as a mobile carrying platform for small rails, involving the fields of railway inspection, patrol, and transportation. By changing the setting form of the walking component and the corresponding control form, the mobile carrying platform can quickly turn around while moving along the track.

[0033] The comfort of passengers is enhanced by providing a seat assembly and a backrest assembly that can be flipped relative to the seat assembly.

[0034] In the existing small rail vehicles and translation devices, there are several problems in actual use:

[0035] When the device or vehicle completes its task and needs to return to the starting point, the device cannot be turned around due to the device structure and track limitations. As a result, the driver needs to twist his body all the time to operate and control the device during the return journey. Long-term operation will cause excessive fatigue and physical injury to the driver.

[0036] If the device needs to be turned, it is usually necessary to disassemble and reassemble it to achieve the purpose of turning the direction, or manually lift the device and turn it around and put it back on the track. This operation will extend the construction period, reduce work efficiency, increase the labor intensity of the operator, and improper operation will cause personal injury and equipment damage. When encountering subway or high-speed rail operations, it is impossible to turn the direction due to the small space.

[0037] See also Figure 1-Figure 2 By setting two sets of switchable operating consoles 11 on the vehicle frame 1, the rotation direction of the running wheels at the bottom of the vehicle frame can be controlled to achieve control adjustment of the vehicle frame 1 in different travel directions, thereby quickly turning around.

[0038] At least two groups of seat assemblies 3 are arranged on the vehicle body frame 1, which can provide at least two rows of seats. Combined with the backrest assembly 4 hingedly connected to the vehicle body frame 1, the backrest assembly 4 can be flipably installed above the seat assembly 3.

[0039] With this arrangement, the backrest assembly 4 can be flexibly folded during the switching of the travel direction, and the backrest can be adaptively provided for leaning on while changing the position of the occupant on the seat assembly 3, thereby enhancing the comfort of the occupant.

[0040] The running wheels arranged at the bottom of the vehicle body frame can effectively drive the vehicle body frame to move on the track. The operating consoles are respectively arranged at the front and rear ends of the vehicle body frame, and are used to install control devices for controlling the operation of the running wheels 2. Through the control consoles 11 located at the front and rear ends of the vehicle body frame, the control devices can be conveniently controlled so that the passengers can control the operation of the running wheels 2 in a sitting position facing the direction of travel.

[0041] An articulated frame 5 is provided between the backrest assembly 4 and the vehicle body frame 1 . A baffle plate 12 is provided on the side of the vehicle body frame 1 . The root of the articulated frame 5 is hingedly connected to the baffle plate 12 .

[0042] The arrangement of the articulated frame 5 can facilitate the flipping of the backrest assembly 4 , and the folding and tilting state of the backrest assembly 4 can be flexibly adjusted based on the baffle 12 .

[0043] Furthermore, in order to enable the backrest assembly 4 to smoothly flip along with the articulated frame 5, a hinge (not shown in the figure) is provided between the articulated frame 5 and the backrest assembly 4, and the hinge is connected to the lateral middle part of the backrest assembly 4. Furthermore, the top end of the articulated frame 5 is connected to the hinge so that the backrest assembly 4 can be flexibly flipped relative to the articulated frame 5 to change the hardness of the backrest assembly 4 during the flipping process.

[0044] The articulated frame 5 includes two support rods 51 which are parallel to each other and arranged in linkage. An armrest frame 31 is provided on the side of the seat assembly 3. After the backrest assembly 4 is flipped relative to the vehicle frame 1, its flipped position is locked by a locking assembly. Specifically, the flipping locking point is limitedly locked on the armrest frame 31 to ensure reliable stability and improve passenger safety.

[0045] The armrest frame 31 is set in a manner that can provide an armrest position for the occupant when the backrest assembly 4 is flipped to different positions, which is conducive to improving the riding experience. The two support rods 51 are set to limit the flipping angle of the seat back and ensure the reliability and stability of the seat back after flipping into place.

[0046] The locking assembly includes a locking seat 32 connected to the handrail frame 31 and a locking pin 33 that can be plugged into the locking seat 32. In the locked state, the locking pin 33 passes through the locking seat 32 and is inserted into the support rod 51.

[0047] Furthermore, in the locked state, the locking pin 33 passes through the locking seat 32 and is inserted into the support rod 51, so as to lock the articulated frame 5 and prevent the position of the articulated frame 5 from changing, and can lock the flipped backrest assembly 4 to the greatest extent. At the same time, the flippable backrest assembly 4 can provide a backrest in different travel directions of the vehicle body frame, greatly improving the riding experience.

[0048] In the specific implementation process, the seat assembly 3 in the present invention includes two groups, and the armrest frames 31 are arranged on both sides of each group of seat assemblies 3. Two locking seats 32 are arranged on each side of the armrest frame 31 to respectively lock the backrest assembly 4 in the flipped position.

[0049] That is, when the backrest assembly 4 is flipped to the left, the articulated frame 5 is locked by inserting the locking pin 33 into the locking seat 32 on the left armrest frame 31, and the same is true when the backrest assembly 4 is flipped to the right.

[0050] The locking seat 32 is provided with an open notch 34 , which includes an avoidance gap on the edge of the locking seat 32 , and can quickly provide a means for the locking pin 33 to be inserted and fixed. During the insertion process, the locking pin 33 can be inserted from the avoidance gap to improve the smoothness.

[0051] On the two oppositely arranged locking seats 32, the open notches 34 are arranged facing each other, and can correspond to the locking of different flipping positions respectively.

[0052] The running wheels 2 are arranged on both sides of the length direction of the vehicle body frame 1, and each pair of running wheels 2 are respectively connected to the two ends of the wheel axle 21, and the wheel axle 21 is connected to the output end of the driving motor. Specifically, the output end of the driving motor can be driven and connected with the wheel axle 21 in different forms. It can be set to a form in which a driving wheel axle and a driven wheel axle cooperate, or it can be set to a form in which two driving wheel axles cooperate. The running wheels can also be set to a four-wheel drive form. The actual setting can be made according to specific needs, which will not be repeated here.

[0053] In order to achieve control in different directions of travel, the control device also includes two sets, and the two sets of control devices can be switched for use. By electrically connecting the control devices to the drive motors respectively, stable and reliable control can be ensured, and the influence of each other on the control devices can be avoided.

[0054] The rail-movable loading platform of the present invention can realize the function of rapid U-turn of the vehicle body frame 1 by arranging control devices in both the forward and backward directions of the vehicle body frame 1.

[0055] By adjusting the position of the seat back, the driver and other passengers can sit in the same direction or in reverse, thus improving the practicality of the device.

[0056] After the seat back is adjusted, it is locked in the flipped state through the locking assembly to improve the safety and comfort of the operator.

[0057] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0058] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
