[0001] The present invention relates to the field of rail transit, and particularly to a magnetic levitation track row linear adjustment device. Background Art

[0002] The magnetic levitation track row is formed by installing a pair of F-shaped rails on a group of sleepers. Generally, it is installed in the workshop and then transported to the site for installation. However, during the installation process, there are still some assembly tolerances that require minor adjustments. The traditional adjustment method is to manually pry the F-shaped rails for adjustment, which is difficult to operate and inconvenient for adjustment.

[0022] The following further describes the track cable line type adjusting device in detail with reference to the drawings and specific embodiments:

[0023] As Figure 1 and Figure 2The shown track wire alignment adjustment device includes a pair of telescopic rods (1a, 1b). This pair of telescopic rods (1a, 1b) are sleeved together and can move relative to each other. A driving mechanism is arranged between this pair of telescopic rods (1a, 1b) to drive the telescopic rods (1a, 1b) to move relative to each other. Here, the relative movement means that the two telescopic rods (1a, 1b) can move away from each other to increase the total length of the two telescopic rods (1a, 1b), or move closer to each other to reduce the total length of the two telescopic rods (1a, 1b). Outer push plates (3a, 3b) and inner push plates (2a, 2b) are respectively arranged at the end parts of each telescopic rod (1a, 1b). As Figure 3 shown, when the adjustment device is in use, the inner push plates (2a, 2b) and the outer push plates (3a, 3b) are respectively placed on the inner side and the outer side of the F rail on the corresponding side.

[0024] The driving mechanism in these two embodiments includes an intermediate plate (4) and a pair of baffle plates (5a, 5b). Among them, the intermediate plate (4) is installed on one of the telescopic rods (1a, 1b), and this pair of baffle plates (5a, 5b) are fixed on the other telescopic rod (1a, 1b). Generally speaking, the intermediate plate (4) is placed between the two baffle plates (5a, 5b). A jack (6) is arranged between the intermediate plate (4) and one of the baffle plates (5a, 5b). By driving the distance between the baffle plate (5a, 5b) and the intermediate plate (4) through the jack (6), the two telescopic rods can be extended or contracted.

[0025] For clear and better differentiation and understanding, these two telescopic rods (1a, 1b) are respectively named the left telescopic rod (1a) and the right telescopic rod (1b). The outer push plates (3a, 3b) and the inner push plates (2a, 2b) installed on the left telescopic rod (1a) are respectively named the left outer push plate (3a) and the left inner push plate (2a). Similarly, the outer push plates (3a, 3b) and the inner push plates (2a, 2b) installed on the right telescopic rod (1b) are respectively named the right outer push plate (3b) and the right inner push plate (2b). The baffle plates (5a, 5b) located on both sides of the intermediate plate (4) are respectively named the left baffle plate (5a) and the right baffle plate (5b).

[0026] As Figure 1 shown in Embodiment 1, both the left baffle plate (5a) and the right baffle plate (5b) are fixed on the right telescopic rod (1b), and the intermediate plate (4) is fixed on the left telescopic rod (1a). When the jack (6) is placed between the left baffle plate (5a) and the intermediate plate (4) as Figure 1 shown, the jack (6) can drive the left telescopic rod (1a) and the right telescopic rod (1b) to move closer to the center, that is, to reduce the distance between the left outer push plate (3a) and the right outer push plate (3b). Refer to Figure 3It can be seen that the distance between the F rails can be reduced at this time, and when the jack (6) is placed between the middle plate (4) and the right baffle (5b), the jack (6) can drive the left telescopic rod (1a) and the right telescopic rod (1b) to extend outward, even if the distance between the left inner push plate (2a) and the right inner push plate (2b) is increased. Figure 3 It can be seen that the spacing between the F rails can be increased at this time, and the linear shape of the rail array can be adjusted in this way. Figure 2 The embodiment 2 shown is only to adjust the positions of the middle plate (4) and the baffles (5a, 5b), that is, the middle plate (4) is fixed on the right telescopic rod (1b), and the left baffle (5a) and the right baffle (5b) are fixed on the left telescopic rod (1a). The positional relationship between the left baffle (5a) and the right baffle (5b) and the middle plate (4) remains unchanged. Under the structure of this embodiment, when the jack (6) is located between the left baffle (5a) and the middle plate (4), the left telescopic rod (1a) and the right telescopic rod (1b) can be driven to extend, so that the distance between the left inner push plate (2a) and the right inner push plate (2b) is increased, thereby increasing the distance between the F rails. Conversely, when the jack (6) is located between the right baffle (5b) and the middle plate (4), the distance between the left outer push plate (3a) and the right outer push plate (3b) can be driven to decrease, thereby reducing the distance between the F rails.

[0027] The left telescopic rod (1a) and the right telescopic rod (1b) are specifically arranged as follows Figure 1 and Figure 2 As shown, the left telescopic rod (1a) is a square tube, and the right telescopic rod (1b) is a channel steel. The square tube is slidably placed in the channel steel. Since the upper end of the channel steel is open, in order to prevent the left telescopic rod (1a) from separating from the right telescopic rod (1b), a limiter is required to limit the left telescopic rod (1a) from tilting upward and separating from the right telescopic rod (1b). The left baffle (5a) and the right baffle (5b) in Example 1 are in a 匚 shape and sit on top of the left telescopic rod (1a) to act as a limiter. Similarly, in Example 2, the middle plate (4) is in a 匚 shape and sits on top of the left telescopic rod (1a) to act as a middle limiter to prevent the left telescopic rod (1a) from separating upward from the right telescopic rod (1b).

[0028] Of course, in addition to the embodiment shown in the figure, which realizes telescopic movement by combining square tubes and channel steel, inner tubes with outer tubes of different diameters can also be used as the left telescopic rod (1a) and the right telescopic rod (1b), as well as conventional structures for assembling two telescopic rods (1a, 1b) to enable relative movement. The specific structure is no longer shown in the figure.

[0029] Figure 1 and Figure 2 The middle and outer push plates (3a, 3b) are arranged in an L-shape at the bottom of the telescopic rods (1a, 1b). In order to increase the strength of the outer push plates (3a, 3b), reinforcing ribs are provided between the outer push plates (3a, 3b) and the telescopic rods (1a, 1b) at their respective positions.Figure 1 and Figure 2 As shown, it is symmetrically fixed on both sides of the telescopic rods (1a, 1b), and the bottom plane protrudes from the lower plane of the telescopic rods (1a, 1b). When moving, it can contact and push the inner side of the F-rail, and on the one hand, it can also provide support for the telescopic rods (1a, 1b) on the sleeper (B).

[0030] During specific operation, refer to Figure 3 , first loosen the connecting piece between the F-rail (A) and the sleeper (B) on the side that needs to be adjusted. Place the device above the sleeper at the position where the gauge needs to be adjusted, so that the left outer pushing plate (3a) and the left inner pushing plate (2a) are respectively placed on the outside and inside of the left F-rail, and the right outer pushing plate (3b) and the right inner pushing plate (2b) are respectively placed on the outside and inside of the right F-rail. When it is necessary to reduce the distance between the two F-rails, place the jack (6) between the left baffle (5a) and the middle plate (4), and drive the jack (6) to make the loose F-rail approach the fixed F-rail through the extrusion between the left outer pushing plate (3a) and the right outer pushing plate (3b) to realize the gauge reduction and adjust the linearity of the track panel. When it is necessary to increase the distance between the two F-rails, place the jack (6) between the middle plate (4) and the right baffle (5b), and drive the jack (6) to make the loose F-rail move away from the fixed F-rail through the outward tension between the left inner pushing plate (2a) and the right inner pushing plate (2b) to realize the gauge increase and adjust the linearity of the track panel.

[0031] The forms of the driving mechanism are diverse. In addition to using the above jack for driving, other methods such as screw rod and nut, gear, chain, and electric push rod can also be used to control the telescoping of the left telescopic rod (1a) and the right telescopic rod (1b), so as to realize the adjustment of the track panel spacing. The following gives two embodiments in conjunction with the drawings:

[0032] As Figure 4 shown in Embodiment 3 of, a mounting seat (1a) is fixedly installed on the right telescopic rod (1b), a fixed seat (8) is fixedly installed on the left telescopic rod (1a), a screw rod (9) is arranged on the mounting seat (7), and a nut (10) cooperating with the screw rod (9) is fixed on the fixed seat (8). The screw rod (9) is movably arranged on the mounting seat (7) so that the screw rod can freely rotate on the mounting seat (7) but cannot move axially. During operation, by rotating the screw rod (9), the nut (10) is driven to move axially along the screw rod (9), thereby driving the telescopic rods (1a, 1b) to telescopic and realizing the linear adjustment of the track panel. In this embodiment, unlike in Embodiment 1 and Embodiment 2, it is not necessary to adjust the jack to realize the extension or contraction of the telescopic rod, but only by rotating the screw rod (9) clockwise or counterclockwise, the extension or contraction of the telescopic rod can be realized, and the operation is more convenient. Of course, the relative positions of the nut (10) and the screw rod (9) can also be interchanged in this embodiment.

[0033] As Figure 5As shown in Embodiment 4, a rack (12) is fixed on the left telescopic rod (1a), and a mounting bracket (11) is fixed on the right telescopic rod (1b). A rotatable gear (13) is movably arranged on the mounting bracket (11). The gear (13) meshes with the rack (12). During operation, driving the gear (13) to rotate forward and backward can drive the rack (12) to move left and right, thereby driving the telescopic rods (1a, 1b) to expand and contract to achieve the linear adjustment of the track panel, which is more convenient compared to the operation of the jack. Similarly, the installation positions of the gear (13) and the rack (12) can also be interchanged. Further, in order to prevent the gear (13) from disengaging from the rack (12), limit plates (14) are provided at both ends of the rack (12).

[0034] For the driving mechanism using the screw rod (9) or the gear (13) as described above, the screw rod (9) or the gear (13) can be driven to rotate by a motor, or manually rotated by a wrench to adjust the track panel.
