[0041] See also Figure 2 and Figure 5The fixed frame 35 includes a vertical beam 22 and a second horizontal beam 21. The second horizontal beam 21 on the top of the fixed frame 35 is equidistantly fixedly connected between the two groups of vertical beams 22. The vertical beam 22 at the bottom of the fixed frame 35 is fixedly connected through the main vertical beam 9 of the transfer frame and the second horizontal beam 21 on the top of the fixed frame 35. A reinforcement beam 20 is fixedly connected between two adjacent groups of main vertical beams 9 of the transfer frame and located at the bottom of the fixed frame 35. A universal hanger 11 is arranged on one side of the reinforcement beam 20. A passive running wheel 10 is rotatably installed on the surface of the universal hanger 11. The surface of the passive running wheel 10 is symmetrically provided with a running wheel limiting plate 24. The passive running wheel 10 is respectively matched with the inner track and the outer track.

[0042] In this embodiment, the corresponding main vertical beams 9, second cross beams 21 and vertical beams 22 of the vehicle body are sequentially arranged and welded to form an integrated frame structure fixing frame 35, which is convenient for installing the passive running wheels 10 and the universal hanger 11, and the passive running wheels 10 and the universal hanger 11 are used for support.

[0043] It should be noted that a support shaft with a U-shaped frame is rotatably installed in the universal hanger 11, and the support shaft rotates in the extension plate 13. Therefore, when the transfer frame moves to the position of the outer track arc rail 7 and the inner track arc rail 8, the passive walking wheel 10 can follow the rotation and roll along the trajectory of the outer track arc rail 7 and the inner track arc rail 8.

[0044] It should be noted that, since the fixed frame 35 and the movable frame 36 are both welded structures, the outside of the transfer frame is wrapped with a body panel 32, which can not only beautify the appearance, but also protect the electrical appliances and lines in the transfer frame.

[0045] See also Figure 1 and Figure 3 The movable frame 36 includes a first cross beam 18, a third cross beam 33 and a top beam 34, wherein two groups of first cross beams 18 are fixedly connected between two groups of third cross beams 33, and another two groups of first cross beams 18 are fixedly connected between two groups of top beams 34, and a vertical beam 19 is fixedly connected between the third cross beams 33 and the top beam 34. The first mounting plate 14 is fixedly installed at one end of the two groups of second cross beams 21, and the first mounting plate 14 is also fixedly connected to the two groups of first cross beams 18. A plane bearing 26 is arranged between the two groups of first mounting plates 14, and a mounting plate 25 is fixedly installed on the surface of the first mounting plate 14 between the first cross beams 18, and the plane bearing 26 is arranged in the mounting plate 25.

[0046] In this embodiment, the corresponding first cross beam 18, vertical beam 19, third cross beam 33 and top beam 34 are sequentially arranged and welded to form an integrated frame structure movable frame 36, and the first mounting plate 14 is fixedly connected to one side of the fixed frame 35 and the top of the movable frame 36 respectively, and the mounting plate 25 is fixedly mounted on the first mounting plate 14 at the top of the movable frame 36, and the plane bearing 26 is connected by the mounting plate 25, and the fixed frame 35 and the movable frame 36 are connected by the plane bearing 26. After the track bending position, the active walking wheel 12 at the bottom of the movable frame 36 can follow the rotation by the plane bearing 26 at the top of the movable frame 36, thereby driving the passive walking wheel 10 to follow the rotation, realizing the universal rotation mechanism of the movable frame 36, and realizing the movement of the transfer frame at the outer track arc rail 7 and the inner track arc rail 8.

[0047] It should be noted that a Yu'ou reinforcement sleeve 28 is provided in the third cross beam 33 at the position where the transmission shaft 27 passes through to ensure the stability of the rotation support structure of the transmission shaft 27 , and a second mounting plate 29 is provided to support the motor 15 .

[0048] See also Figure 3 A transmission shaft 27 is rotatably mounted between the third cross beam 33, and active travel wheels 12 are fixedly mounted at both ends of the transmission shaft 27. Two sets of travel wheel limit plates 24 are also symmetrically arranged on the surface of the active travel wheel 12.

The transmission shaft 27 is connected to the output shaft of the dual-axis reducer 16, and the dual-axis reducer 16 is fixedly mounted in the fixed frame 35 through a support plate 17.

[0049] In this embodiment, the motor 15 is started. Since the motor 15 is connected to the dual-axis reducer 16, it should be noted that the dual-axis reducer 16 is connected to the motor 15 and the transmission chain 23, and the internal reduction transmission structure of the dual-axis reducer 16 drives the transmission shaft 27 to rotate, thereby realizing the rotation of the active walking wheel 12, thereby driving the entire transfer frame to move on the track.

[0050] Embodiment 2:

[0051] See also Figure 7 and Figure 8Based on the first embodiment, due to the working environment of the above-mentioned track and transfer frame, and the influence of the components of the transfer limit, dust and dirt are easily accumulated on the surface of the track, which will hinder the rolling of the travel wheels of the transfer frame, reduce the transportation speed of the rail vehicle, and reduce the transportation efficiency. Therefore, a slidingly mounted brush cleaning assembly is provided on the front side of the movable frame 36, and the brush cleaning assembly includes a brush roller 38 and a brush head rotatably mounted on both ends of the brush roller 38. A first ear plate 41 is fixedly mounted on one side of the bottom end of the vertical beam 19, and the brush roller 38 is slidably mounted between the two groups of first ear plates 41. A linkage plate 40 is fixedly mounted on the surface of the brush roller 38, and the linkage plate 40 is slidably mounted on one side of the first cross beam 18. A spring 39 is fixedly connected between the linkage plate 40 and the first ear plate 41 and located outside the brush roller 38. A first synchronous pulley 37 is fixedly mounted on the surface of the transmission shaft 27, a transition shaft 48 is rotatably mounted on the upper surface of the first beam 18 through a second ear plate 42, a second synchronous pulley 43 is fixedly mounted on the surface of the transition shaft 48, a bevel gear 44 is fixedly mounted on one end of the third beam 33, a shaft 45 is rotatably mounted on one side of the first beam 18, a bevel gear 44 is also fixedly mounted on one end of the shaft 45, the two sets of bevel gears 44 are transmission connected, one end of the shaft 45 is connected to a ball head lever 47 through a fixed sleeve 46, and when the ball head lever 47 rotates, it will push the linkage plate 40 to drive the brush roller 38 to move back and forth horizontally.

[0052] In this embodiment, after the entire transfer frame is started, the transmission shaft 27 is driven by the motor 15 and the dual-axis reducer 16, and the transmission shaft 27 rotates. Due to the transmission connection between the first synchronous pulley 37 and the second synchronous pulley 43, the transmission shaft 27 drives the transition shaft 48 to rotate, so that the meshing of the two sets of bevel gears 44 drives the shaft 45 to rotate. Since the surface of the shaft 45 is fixedly connected with the fixing sleeve 46 and the ball head lever 47 in sequence, during the rotation of the ball head lever 47, the ball head lever 47 will push the linkage plate 40 to drive the brush roller 38 to move horizontally on one side of the transfer frame. Since the spring 39 is fixedly connected between the linkage plate 40 and the first ear plate 41, when the linkage plate 40 drives the brush roller 38 moves the passive walking wheel 10 to one side, the spring 39 is extended by the tension, and the brush heads at both ends slide on the upper surface of the track top plate 6. When the ball head lever 47 is turned to the away side of the linkage plate 40, the spring 39 is reset, driving the brush roller 38 to reset, thereby realizing the reciprocating movement of the brush roller 38 in the horizontal direction, thereby cleaning the surface of the track top plate 6. During the movement, the brush head and the brush roller 38 are rotationally connected. Therefore, when not being moved by the ball head lever 47, a certain friction force will be generated with the inner track and the outer track, that is, the surface of the track top plate 6 of the inner track and the outer track can be cleaned, thereby ensuring the smooth rolling of the walking wheels of the transfer frame, thereby ensuring the transportation speed and efficiency of the rail vehicle.

[0053] Working principle: During use, the device uses the power slotted sliding line 4 and the power connection part 31 to draw power, start the motor 15, and drive the transmission shaft 27 connected between the active walking wheels 12 to rotate through the transmission of the motor 15 and the double-axis reducer 16, thereby driving the active walking wheels 12 to rotate, and driving the entire transfer frame to move on the track;

[0054] Since the present application has two sets of first mounting plates 14 between the movable frame 36 and the fixed frame 35, and a plane bearing 26 is installed on the surface of the lower first mounting plate 14, a central axis rotation structure is formed between the movable frame 36 and the fixed frame 35. When the transfer frame travels to the setting position of the outer track arc rail 7 and the inner track arc rail 8 at the track bending position, the active running wheel 12 at the bottom of the movable frame 36 can follow the rotation using the plane bearing 26 at the top of the movable frame 36, thereby driving the passive running wheel 10 to follow the rotation, realizing the universal rotation mechanism of the movable frame 36, and realizing the travel of the transfer frame at the position of the outer track arc rail 7 and the inner track arc rail 8;

[0055] At the same time, considering that dust and dirt are easily accumulated on the upper surface of the track top plate 6, which will hinder the rolling of the running wheels of the transfer frame, the ball head lever 47 is used to move the linkage plate 40 to drive the brush roller 38 and the brush heads at both ends to reciprocate horizontally on the front side of the frame. During the movement, the brush head and the brush roller 38 are rotationally connected. Therefore, when not moved by the ball head lever 47, a certain friction force will be generated with the inner track and the outer track, that is, the surface of the track top plate 6 of the inner track and the outer track can be cleaned, ensuring the smooth rolling of the running wheels of the transfer frame, thereby ensuring the transportation speed and efficiency of the rail vehicle.

[0056] It should be noted that the contacts of the power slot-shaped sliding line 4 and the power connection part 31 are always arranged in close contact and are supporting facilities.

[0057] It should be noted that the motor is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
