Rail wheel engaging and releasing mechanism

Abstract

This utility model discloses a track wheel locking and releasing mechanism, including a plate body. A first groove is formed at the top of the plate body, and a linear drive device is fixed to the top of the plate body. A rotating plate is inserted into the first groove, and the rotating plate is rotatably connected to the plate body via a connecting device. A locking block is provided at the bottom of the rotating plate. An oblong hole is formed on the side of the rotating plate above the plate body, and a first shaft is disposed within the oblong hole. A connecting plate is fixed to the output shaft of the linear drive device, and the connecting plate is fixedly connected to the first shaft. Compared with the prior art, the linear drive device of this utility model can indirectly cause the locking block to rotate counterclockwise. At this time, the locking block can apply a force to the track wheel inside and open the movement path of the track wheel. Combined with the gravitational potential energy of the track wheel, it ensures smooth disengagement and prevents the track wheel from remaining stationary due to insufficient gravitational potential energy to overcome the friction between the track wheel and the track.

Description

Technical Field

[0001] This utility model relates to the field of track conveying technology, and in particular to a track wheel locking and release mechanism. Background Technology

[0002] In the textile production, warehousing, and retail sectors, hanger hanging conveyor systems are core equipment for realizing the bulk flow of garments. Among these systems, the track wheels, as key components that drive the hangers along the track, directly affect the system's operational efficiency through the smoothness of their engagement and disengagement. Currently, the commonly used track wheel engagement and disengagement structures in this field mostly rely on the simple adaptation of the track wheels and engagement components to achieve positioning. During disengagement, the engagement constraint is simply released, and the hangers and track wheels themselves are driven by gravity potential energy to slide along the track to complete the transfer, sorting, or storage of garments. However, due to the differences in weight between textile hangers and garments, and the accumulation of fiber dust and slight wear on the track over long-term use, the frictional resistance between the track wheels and the track becomes unstable. When the frictional resistance is high or the load is low, the gravitational potential energy of the track wheels and hangers alone is often insufficient to overcome the frictional resistance, which can easily lead to the track wheels becoming stuck and causing the hanger conveying to be interrupted. This not only affects the efficiency of textile circulation but may also cause subsequent hanger accumulation and track blockage, requiring frequent manual intervention and adjustment, which increases labor costs and operational risks. Utility Model Content

[0003] The main purpose of this utility model is to provide a track wheel locking and releasing mechanism. The linear drive device can indirectly make the locking block rotate counterclockwise. At this time, the locking block can apply force to the track wheel inside and open the track wheel's movement path. The track wheel's gravitational potential energy is used to ensure its smooth release and prevent the track wheel from being unable to overcome the friction between the track wheel and the track due to the track wheel's gravitational potential energy being unable to overcome the friction between the track wheel and the track, thus causing the track wheel to remain stationary.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A track wheel locking and releasing mechanism includes a plate body, a first groove on the top of the plate body, a linear drive device fixed on the top of the plate body, a rotating plate inserted in the first groove, the rotating plate being rotatably connected to the plate body via a connecting device, a locking block at the bottom of the rotating plate, an oblong hole on the side of the rotating plate located above the plate body, a first shaft body disposed in the oblong hole, and a connecting plate fixed on the output shaft of the linear drive device, the connecting plate being fixedly connected to the first shaft body.

[0005] Furthermore, the connecting device includes a mounting plate disposed at the bottom of the plate body, a second groove being provided on the mounting plate, positioning plates being provided on both sides of the bottom of the mounting plate, and the rotating plate passing through the second groove and rotatably connected between the two positioning plates via a second rotating shaft.

[0006] Furthermore, it also includes two L-shaped plates arranged opposite each other, the two L-shaped plates being fixed to the bottom of the plate body to form a slot, and the mounting plate being inserted into the slot.

[0007] Furthermore, the bottom of the L-shaped plate is threaded with several fixing screws for locking the mounting plate.

[0008] Furthermore, the connecting plate is U-shaped, and its two sides are fixedly connected to both ends of the first shaft.

[0009] Furthermore, the card block is figure-eight shaped, and the card slot of the card block is arc-shaped.

[0010] Furthermore, the linear drive device is a cylinder.

[0011] Furthermore, the second tank and the first tank are positioned to match.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The linear drive device of this utility model can indirectly make the locking block rotate counterclockwise. At this time, the locking block can apply force to the internal track wheel and open the movement path of the track wheel. With the gravitational potential energy of the track wheel, it can ensure that the track wheel can be smoothly released and prevent the track wheel from being unable to overcome the friction between the track wheel and the track due to the gravitational potential energy of the track wheel.

[0013] In the connecting device of this utility model, the mounting plate can be inserted into the slot formed by the L-shaped plate. By adjusting the position of the mounting plate, the position of the second slot relative to the first slot can be changed, thereby controlling the maximum angle of counterclockwise rotation of the rotating plate. This avoids the jamming block from failing to reset in time due to excessive rotation angle of the rotating plate, thus limiting the subsequent track wheel.

[0014] The locking block of this utility model is designed in the shape of an "eight" and the slot is arc-shaped, which can increase the contact area with the track wheel, effectively improve the locking stability, and prevent the track wheel from loosening or shifting when it is ready to be transported.

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] like Figure 1-5As shown, a track wheel locking and releasing mechanism includes a plate 1, a first groove 2 on the top of the plate 1, a linear drive device 5 (a cylinder) fixed to the top of the plate 1, a rotating plate 3 inserted into the first groove 2, the rotating plate 3 being rotatably connected to the plate 1 via a connecting device, a U-shaped connecting plate 4, the two sides of the connecting plate 4 being fixedly connected to the two ends of a first shaft 8 by bolts, a locking block 11 at the bottom of the rotating plate 3, and a waist-shaped hole 301 on the side of the rotating plate 3 above the plate 1, the first shaft 8 being disposed within the waist-shaped hole 301 and movable within the waist-shaped hole 301, the connecting plate 4 being fixedly connected to the first shaft 8, as shown. Figure 1 As shown, when the linear drive device 5 retracts, it will drive the rotating plate 3 to rotate counterclockwise, so that the track wheel fixed by the locking block 11 can slide on the track. During this process, the first shaft 8 will move in the waist-shaped hole 301, thereby overcoming the height change caused by the rotation of the rotating plate 3. When the linear drive device extends and resets, the locking block 11 is also reset, thereby continuing to engage the corresponding track wheel.

[0026] Specifically, the elongated track wheel is fixed by the locking block 11. When the linear drive device 5 retracts, the rotating plate 3 rotates counterclockwise, causing the locking block 11 to rotate counterclockwise by a certain angle. This allows the track wheel locked by the locking block 11 to disengage from the locking block 11 and move on the track. Furthermore, as the locking block 11 rotates counterclockwise, the distance between the bottom of the locking block 11 and the track is greater than the diameter of the track wheel. Therefore, subsequent track wheels can re-enter the locking block 11. At this time, the linear drive device 5 drives the rotating plate 3 to rotate clockwise, thereby resetting the angle of the locking block 11. This allows the locking block 11 to lock the track wheels that subsequently enter it, preventing multiple track wheels from being transported on the track at the same time.

[0027] In this embodiment, such as Figure 1 , Figure 3 and Figure 4As shown, the connecting device includes a mounting plate 7 located at the bottom of the plate 1. A second groove 701 is provided on the mounting plate 7, and the second groove 701 is matched with the first groove 2. Positioning plates 10 are provided on both sides of the bottom of the mounting plate 7. The rotating plate 3 passes through the second groove 701 and is rotatably connected between the two positioning plates 10 via the second rotating shaft 9. It also includes two L-shaped plates 6 arranged opposite each other. The two L-shaped plates 6 are fixed to the bottom of the plate 1 to form a slot. The mounting plate 7 is inserted into the slot, which makes the mounting plate 7 easy to install and remove. Furthermore, by changing the installation position of the mounting plate 7, the position of the second groove 701 relative to the first groove 2 is adjusted, thereby controlling the maximum rotation angle of the rotating plate 3 when it rotates counterclockwise (when the rotating plate 3 touches the inner wall of the second groove 701 when it rotates, it cannot rotate again. In this scheme, the linear drive device is a cylinder with adjustable stroke selection). This avoids the rotating plate 3 from rotating too much, which would cause the locking block 11 to fail to reset in time and limit the subsequent track wheel.

[0028] Among them, such as Figure 4 As shown, the bottom of the L-shaped plate 6 is threaded with several fixing screws 13 for locking the mounting plate 7. Once the position of the mounting plate 7 is determined, the operator can rotate the fixing screws 13 so that their tops press against the mounting plate 7, thereby fixing the position of the mounting plate 7.

[0029] Among them, such as Figure 5 As shown, the locking block 11 is figure-eight shaped, and the locking groove 12 of the locking block 11 is arc-shaped. The arc shape has a larger contact area with the track wheel, resulting in better locking stability. Furthermore, when the locking block 11 rotates counterclockwise, it can apply a certain force to the track wheel, which, combined with the gravitational potential energy of the track wheel, allows the track wheel to slide on the track.

[0030] Working principle: In the initial state, the track wheel is locked and fixed by the locking block 11. When the linear drive device 5 retracts, its output shaft drives the connecting plate 4 to move, and the first shaft 8 fixed to the connecting plate 4 moves accordingly. Since the first shaft 8 is located in the waist-shaped hole 301 of the rotating plate 3, it will move within the waist-shaped hole 301 to overcome the height change when the rotating plate 3 rotates, thereby driving the rotating plate 3 to rotate counterclockwise around the second rotating shaft 9. When the rotating plate 3 rotates counterclockwise, it drives the locking block 11 at the bottom to rotate counterclockwise at a certain angle. On the one hand, it no longer locks the track wheel inside and applies a force to the track wheel. Combined with the gravitational potential energy of the track wheel, it causes the track wheel to detach from the locking block 11 and slide on the track. On the other hand, the distance from the bottom of the locking block 11 to the track is greater than the diameter of the track wheel, which facilitates the subsequent track wheel to enter the locking block 11. When the linear drive device 5 extends and resets, it will drive the rotating plate 3 to rotate clockwise, so that the angle of the locking block 11 is reset and the subsequent track wheel is locked again, avoiding multiple track wheels from being transported at the same time, so as to realize the locking and release operation of the track.
