Description

Technical Field

[0001] The utility model relates to the technical field of conveying track equipment, in particular to an elastic sliding bed plate with an automatic resetting function. Background Art

[0002] At present, mining is mainly carried out by rail transportation. In some small mines, since there is no signal collection and closing system during infrastructure construction, manual switchmen are installed at the switches, and the manual switchmen are used to convert the switches. However, the safety factor of the manual switchmen is low when used.

[0003] In response to this technical problem, the Chinese utility model patent application number 2019220600393 discloses an automatic reset transport track. Figure 8 , which includes a straight base rail (1), a curved base rail (2), a straight connecting rail (3), a curved connecting rail (4), a straight auxiliary rail (5), a curved auxiliary rail (6), a fixed column (8), a spring (9), a connecting rod (7), and a connecting column (10). A straight connecting rail (3) and a curved connecting rail (4) are installed between the straight base rail (1) and the curved base rail (2). The straight connecting rail (3) and the curved connecting rail (4) are hinged to the ground at the fork through the connecting column (10); the end of the straight connecting rail (3) and the end of the curved connecting rail (4) are connected through the connecting rod (7). A fixed column (8) is provided on the outside of the curved base rail (2). The bottom end of the fixed column (8) is fixed to the ground. One end of the spring (9) is connected to the fixed column (8) and the other end is connected to the connecting rod (7). By adopting the above method, the spring 9 can provide elastic tension to the curved connecting rail 4 and the straight connecting rail 3. Under the action of the elastic force, the state of the curved connecting rail 4 and the straight connecting rail 3 is as follows Figure 1 As shown in the figure, when the vehicle runs from A to B, the straight connecting rail 3 is separated from the straight base rail 1. At this time, the vehicle can pass through the straight base rail 1 and the curved connecting rail 4 to B. When the vehicle runs from C to A, when the vehicle passes through the curved base rail 2 and the straight connecting rail 3, the vehicle can apply a thrust to the straight connecting rail 3 under the action of its own gravity, causing the straight connecting rail 3 to displace and rest against the straight base rail 1, stretching the spring 9, and pulling the curved connecting rail to separate from the curved base rail 2. After the vehicle passes, it resets under the tension of the spring, thereby achieving the purpose of automatic reset.

[0004] However, since the end of the spring is fixed to the fixing column 8, the fixing column is generally set on the sleeper and is a fixed setting. After the spring is used for a long time and stretched repeatedly, there will be insufficient rebound force, resulting in the curved connecting rail 4 not fitting tightly with the curved base rail. When the vehicle moves from A to B, when the curved connecting rail 4 does not fit tightly, the wheel will impact the tip of the curved connecting rail, causing the tip to wear quickly: the current solution is to replace the spring 9 or set a fixed column 8 at a longer distance on the sleeper again, and set a fixed column 8 at a longer distance to connect with the spring again, so as to increase the stretching amount of the spring. The method of replacing the spring 9 is wasteful. By setting multiple fixing columns 8, multiple fixed positions need to be set on the sleeper, and the setting method of the fixing column mostly adopts the setting of drilling fixing holes on the sleeper, which will affect the overall strength of the sleeper.

DETAILED DESCRIPTION

[0024] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0025] Please refer to Figure 1-5 To achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an elastic sliding bed plate with automatic reset function, comprising a sleeper 21, a pad 22 and a table 23 arranged on the sleeper, and further comprising:

[0026] Adjustment assembly 25; a mounting frame 253 capable of displacement adjustment along the length direction of the sleeper 21, wherein the mounting frame 253 is provided with a mounting hook 254 for engaging with the spring 9.

[0027] Specifically, refer to Figure 1The sleeper is a strip structure, one end of the sleeper is provided with a pad 22, a table 23 and an adjustment assembly 25, and the other end of the sleeper is provided with a pad 22 and a table 23, wherein the pad 22 is locked on the sleeper by a first fixing bolt 24. When in use, the arrangement of the sleeper is consistent with that in the prior art, and is arranged directly below the straight base rail 1, the curved base rail 2, the straight connecting rail 3 and the curved connecting rail 4, and the straight connecting rail 3 and the curved connecting rail 4 are respectively arranged directly above the two pads 22, and the straight connecting rail 3 and the curved connecting rail 4 can respectively slide with the two table plates 23, and one end of the spring 9 is connected to the hook 254 The hook connection, the other end is connected to the curved connecting rail 4, the curved connecting rail 4 and the straight connecting rail are connected by a connecting rod 7, and the spring 9 provides elastic force for the curved connecting rail 4 and the straight connecting rail. Through this setting, when the spring is stretched and the rebound force is insufficient after a period of use, the spring 9 can be separated from the hanging frame first, and then the displacement adjustment is performed through the adjustment component 25 to adjust the position of the hanging frame away from the curved connecting rail, and then the end of the spring 9 is hung on the hanging frame again to increase the stretching amount of the spring 9. The displacement adjustment can be performed through the adjustment component 25 to perform displacement compensation to ensure that the spring has sufficient elastic force.

[0028] Furthermore, the adjustment assembly 25 includes an adjustment member 250 , which is provided with a wing plate 2500 that slides with the pad 22 , and a strip hole 2501 is provided on the wing plate 2500 , and the pad 22 is provided with a threaded hole 221 corresponding to the strip hole 2501 .

[0029] Specifically, by setting a wing plate 2500, the wing plate 2500 slides with the pad 22, and a strip hole 2501 is set on the wing plate 2500. When fixing the adjusting member 250, the second fixing bolt 2502 can be extended into the strip hole 2501 and threadedly connected to the threaded hole 221, and then the wing plate 2500 is locked by the second fixing bolt 2502 to achieve a locking effect. When adjusting the position of the adjusting member 250, it is only necessary to loosen the second fixing bolt 2502, then slide it along the length direction of the strip hole, and then lock it again.

[0030] Further, as a specific embodiment, refer to Figure 3-Figure 7 The adjustment assembly 25 further includes a first one-way ratchet 2510 disposed on the backing plate 22, and the adjustment member 250 is provided with a second one-way ratchet 2520 that cooperates with the first one-way ratchet 2510 to limit the position in one direction. Specifically, the second one-way ratchet 2520 disposed on the adjustment member 250 unidirectionally cooperates with the first one-way ratchet 2510 to limit the position of the adjustment member 250 in one direction. This cooperation method is simple and reliable in structure, and facilitates subsequent position adjustment of the adjustment member 250 through the one-way ratchet cooperation.

[0031] Furthermore, as a specific embodiment, a guide cavity 2504 is vertically arranged on the lower surface of the adjusting member 250, a second plate 252 is guided in the guide cavity 2504, an elastic member is arranged between the second plate and the adjusting member, the elastic member can provide a downward elastic force to the second plate, and the second one-way ratchet 2520 is arranged on the lower surface of the second plate.

[0032] Specifically, by setting a guide cavity 2504, the second plate is set in the guide cavity 2504, and the second one-way ratchet 2520 is set on the lower surface of the second plate. The elastic member provides a downward elastic force to the second plate 252, so that the second plate 252 is fitted on the first one-way ratchet 2510. Through this setting, when adjusting the adjusting member 250 in the direction away from the curved connecting rail 4, it is only necessary to separate the adjusting member 250 from the pad 22, and then slide the adjusting member 250. During the sliding process, the elastic member can be compressed to drive the second plate 252 to move synchronously during the movement, thereby facilitating the adjustment of the adjusting member 250.

[0033] Further, as a preferred embodiment, refer to Figure 6 The bottom surface of the guide cavity 2504 is provided with at least one guide post 2503, and the second plate 252 is provided with a guide hole 2521 for guiding and cooperating with the guide post. Specifically, through this arrangement, the adjustment member 250 and the second plate 252 can be better guided and matched.

[0034] Furthermore, as a preferred embodiment, the elastic member is a compression spring 255 provided between the second one-way limiting plate and the bottom surface of the guide cavity 2504 .

[0035] Furthermore, as a specific embodiment, a first plate 251 is provided on the backing plate 22, and the first one-way ratchet is integrally provided with the first plate 251. Avoidance openings 2505 communicating with the guide cavity 2504 are provided on opposite sides of the adjusting member 250. Specifically, the first plate 251 can be detachably fixedly connected to the backing plate 22 via screws, or can be welded to the backing plate 22. In this manner, the first one-way ratchet can be manufactured on the first plate, and then the first plate can be connected to the backing plate 22, thereby facilitating the processing of the first one-way ratchet on the backing plate 22. The avoidance openings 2505 are provided to avoid the first plate 251, so that the first plate does not hinder the position adjustment of the adjusting member.

[0036] The working principle of the elastic sliding bed plate with automatic reset function provided by the present application is as follows: the first plate 251 is set on the pad 22, and then the second plate 252 is placed above the first plate 251, and the first one-way ratchet and the second one-way ratchet are matched in one direction, and then the compression spring 255 is placed on the first plate and corresponds to the guide hole 2521, and then the adjustment member 250 is buckled on the second plate 252, and the guide column 2503 is passed through the compression spring and the guide hole, and the second plate is placed in the guide cavity 2504, and the adjustment member 250 is provided with downward pressure to squeeze the compression spring 255, so that the lower surface of the wing plate is aligned with the pad The upper surface of the plate 22 is in contact, and then the second fixing bolt 2502 is used to fix and lock the wing plate, thereby fixing the adjusting member 250, and then the spring 9 connected to the curved connecting rail 4 is hung on the hanging hook 254 to achieve the connection of the spring 9. When the stretching amount of the spring 9 needs to be adjusted, first separate the spring 9 from the hanging hook 254, then loosen the second fixing bolt 2502 by 3-5 mm, and then push the adjusting member to slide away from the curved connecting rail. After sliding to the appropriate position, tighten the second fixing bolt 2502 again to hang the spring 9 on the hanging hook.
