[0019] Embodiment:

[0020] As Figures 1 - 3 shown, this embodiment provides a main frame limit component for a sleeper separation platform, including a fixed bracket 1, a linear guide rail 2, an electric push rod 3, and a conical guide plate 4. The linear guide rail 2 includes a positioning block 201 and a slide bar 202. The positioning block 201 is installed on the fixed bracket 1, and a limit chute extending in the vertical direction is provided on the positioning block 201. The slide bar 202 is slidably connected in the limit chute. The matching structure of the positioning block 201 and the slide bar 202 belongs to a conventional linear guide rail structure, with simple and stable technology. The conical guide plate 4 is installed on the slide bar 202, and the upper part of the conical guide plate 4 is a conical limit part with a width gradually increasing from top to bottom. In practice, when the sleeper is placed on the sleeper separation platform, the linear guide rail 2 controls the conical guide plate 4 to rise, and then the position of the sleeper is adjusted. The conical limit part is used as the limit when the sleeper moves. As long as the sleeper contacts the conical limit part, the positions of all sleepers can be adjusted in place. The width of the conical limit part gradually increases from top to bottom, which can avoid damage to the sleeper as much as possible when the sleeper contacts the conical limit part. The height of the conical limit part in the horizontal direction is higher than the height of the upper end of the slide bar 202 in the horizontal direction, thereby ensuring that the sleeper contacts the conical limit part. The electric push rod 3 is installed on the fixed bracket 1, and the telescopic rod of the electric push rod 3 is connected to the slide bar 202 to control the slide bar 202 to slide up and down along the limit chute through the electric push rod 3, and the lifting adjustment of the conical guide plate 4 can be easily realized.

[0021] When the utility model is in use, it can be installed in advance at a position on the side of the sleeper separation platform as needed. The electric push rod 3 is used to control the lifting of the sliding rod 202 of the linear guide rail 2, and then the conical guide plate 4 can be driven to lift. Before placing the sleeper on the sleeper separation platform, the conical guide plate 4 remains at a relatively low position on the side of the sleeper separation platform, thus not affecting the placement of the sleeper on the sleeper separation platform. Then, the sleeper separation platform is controlled to rise through the linear guide rail 2, and then the position of the sleeper is moved so that the sleeper contacts the conical limiting part of the conical guide plate 4, and the sleeper can be limited. Furthermore, through the limitation, all sleepers can be accurately positioned to the specified position, ensuring the accuracy of the spacing between sleepers, and thus ensuring that subsequent operations are not affected.

[0022] As a preferred implementation in this embodiment, it should be further noted that the fixed bracket 1 is of a U-shaped structure. Both ends of the fixed bracket 1 are connected to the side surface of the sleeper separation platform. The positioning block 201 is installed on the surface of the fixed bracket 1 near the sleeper separation platform and close to the middle part. The limiting chute is opened on the surface of the positioning block 201 near the sleeper separation platform. The conical guide plate 4 is installed on the surface of the sliding rod 202 near the sleeper separation platform, so that the conical guide plate 4 is as close as possible to the sleeper separation platform, thus ensuring that the conical guide plate 4 can contact the sleeper and achieve the limiting effect.

[0023] As a preferred implementation in this embodiment, it should be further noted that the electric push rod 3 is installed on a positioning plate 5. The positioning plate 5 is located on the other side of the middle part of the fixed bracket 1. The positioning plate 5, the fixed bracket 1 and the positioning block 201 are connected by the first bolt 6. The structural layout is reasonable and the overall length is not too long, thus not affecting the height adjustment of the sleeper separation platform. The connection between the electric push rod 3 and the sliding rod 202 can select connecting plates or connecting rods of different shapes according to needs.

[0024] As a preferred implementation in this embodiment, it should be further noted that the positioning plate 5 is provided with a first bolt connection hole. The middle part of the fixed bracket 1 is provided with a horizontal long hole extending towards its two side plates. The first bolt 6 passes through the first bolt connection hole and the horizontal long hole in sequence and is threadedly connected to the positioning block 201. Furthermore, by adjusting the screw part of the first bolt 6 in the horizontal long hole, the position of the conical guide plate 4 can be appropriately adjusted. In practice, it can be adjusted according to different requirements, improving the applicability.

[0025] As a preferred implementation scheme in this embodiment, it needs to be further explained that the telescopic rod of the electric push rod 3 is connected to the slide rod 202 through an L-shaped frame 7, one end of the L-shaped frame 7 is connected to the telescopic rod of the electric push rod 3, and the other end of the L-shaped frame 7 is connected to the lower end of the slide rod 202. The middle part of the L-shaped frame 7 and the lower end of the fixed bracket 1 and the lower end of the positioning block 201 all maintain a sliding distance that facilitates the conical limiting part to slide upward to above the pillow sub-platform, ensuring that the electric push rod 3 can stably control the slide rod 202 to slide in the limiting groove of the positioning block 201.

[0026] As a preferred implementation scheme in this embodiment, it needs to be further explained that a retaining ring 8 is installed on the fixed bracket 1, and the retaining rings 8 cooperate with each other to form an annular protective chamber. The electric push rod 3 is installed in the annular protective chamber, which can provide a certain protection effect for the electric push rod 3 and prevent the electric push rod 3 from being damaged by contact with foreign objects.

[0027] As a preferred implementation scheme in this embodiment, it needs to be further explained that the conical guide plate 4 is detachably connected to the slide rod 202 through the second bolt 9, and at least one vertical long hole is opened on the conical guide plate 4. The screw portion of the second bolt 9 passes through the vertical long hole and is threadedly connected to the slide rod 202, and the nut portion of the second bolt 9 abuts against the conical guide plate 4. Then, the height of the conical limiting portion can be appropriately adjusted according to actual conditions to improve applicability.

[0028] As a preferred implementation scheme in this embodiment, it needs to be further explained that the two sides of the conical limiting part are respectively arranged corresponding to the two ends of the sleeper platform, and both sides of the conical limiting part are inclined surfaces, so that the conical limiting part can avoid damage as much as possible when contacting with the sleeper.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
