Swing type gate machine core

Abstract

The utility model relates to the technical field of gate machines, and discloses a swing type gate machine core which comprises a machine case and a swing column rod rotationally connected to the upper surface of the machine case, and a speed reducer is arranged in the middle of the inner wall of the machine case. According to the swing type gate machine core, the driving controller, the clutch, the transmission spline and the electromagnetic ring are matched for use, so that when the swing type gate machine core operates normally, the rotary spline sleeve is meshed with the transmission spline, and when the swing piece is forcibly pushed by external force, the driving controller judges whether the external force exists or not according to the angle change of the incremental encoder in the servo motor; after an external force is detected, the driving controller starts the electromagnetic ring and the clutch to move downwards, and the rotary spline housing is separated from the transmission spline, so that the servo motor can be timely separated from the transmission system when the swing sheet is forcibly pushed by the external force, the risk of over-rotation of the servo motor is further avoided, and the service life of the movement servo motor is further prolonged.

Description

Technical Field

[0001] This utility model relates to the field of turnstile technology, specifically to a swing-type turnstile mechanism. Background Technology

[0002] With the rapid development of the social economy, the public's travel demand is increasing day by day. To ensure passenger safety, control equipment such as turnstiles frequently perform automatic ticket checking and access identification tasks in crowded public places such as scenic spots, amusement parks, and subway stations. These places usually have high traffic volume, so the requirements for safety and efficiency are extremely high. Swing turnstiles are widely adopted because of their fast opening and closing action and safe passage capability. Their design aims to provide a fast and safe passage method to meet the needs of high traffic environments. However, there are some problems with current swing turnstiles. When using existing swing turnstiles, tourists often forcefully push the swing plate. The input shaft of the swing plate is connected to the servo motor. Forcibly pushing the swing plate will cause the servo motor to over-rotate, affecting the service life of the servo motor of the mechanism. Utility Model Content

[0007] The clutch includes a rotating sleeve fitted on the outer surface of the output shaft. A transmission key is fixedly connected to the outer surface of the output shaft. A transmission keyway adapted to the transmission key is opened at the bottom of the inner wall of the rotating sleeve. A spline is fixedly connected to the bottom of the outer surface of the rocker rod. A rotating spline sleeve is fixedly connected to the upper surface of the rotating sleeve.

[0008] A fixed post, which is fixedly connected to the reducer, is slidably inserted into the inner wall of the fixed collar. A limit ring is fixedly fitted in the middle of the outer surface of the fixed post. A spring is fitted in the top of the outer surface of the fixed post. A drive controller is provided on the right side of the outer surface of the chassis. An electromagnetic ring is fixedly fitted in the bottom of the outer surface of the fixed post. The output end of the drive controller is electrically connected to the input end of the servo motor and the electromagnetic ring.

[0009] Preferably, a pendulum is fitted onto the top of the outer surface of the pendulum rod, and a pendulum plate is connected to the left side of the outer surface of the pendulum rod.

[0010] Preferably, two sets of support plates are fixedly connected to the bottom of the inner wall of the chassis, and four sets of fixing bolts are inserted into the bottom of the outer surface of the reducer housing, with the fixing bolts threadedly connected to the support plates.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a swing-type gate mechanism, which has the following beneficial effects:

[0016] 1. This swing gate mechanism, through the coordinated use of a drive controller, clutch, transmission spline, and electromagnetic ring, ensures that during normal operation, the rotating spline sleeve engages with the transmission spline. When an external force forces the swing plate, the drive controller determines whether an external force is applied by observing the angle change of the incremental encoder inside the servo motor. Upon detecting the external force, the drive controller activates the electromagnetic ring, the clutch moves downward, and the rotating spline sleeve disengages from the transmission spline. This allows the servo motor to disengage from the transmission system promptly when the swing plate is forcibly pushed by an external force, further avoiding the risk of over-rotation of the servo motor and extending the service life of the mechanism's servo motor.

[0017] 2. The swing gate mechanism uses a fixed spline sleeve, a fixed collar, a fixed column, and a fixed frame in combination. This allows the rotating spline sleeve to separate from the transmission spline while simultaneously moving the fixed spline sleeve downwards via the connecting frame. The fixed spline sleeve then engages with the transmission spline and is fixedly connected to the fixed collar, preventing it from rotating. Simultaneously, the fixed spline sleeve locks the swing column rod, enabling the device to lock the swing plate the moment it is forcibly pushed by external force, thus preventing forced entry by personnel.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7This utility model provides a technical solution: a swing gate mechanism, including a housing 1 and a swing column rod 2 rotatably connected to the upper surface of the housing 1. The feature is that a reducer 3 is provided in the middle of the inner wall of the housing 1. The reducer 3 includes a reducer housing 301 and an input shaft 302 and an output shaft 303 rotatably connected to the front and rear sides of the reducer housing 301. The input shaft 302 and the output shaft 303 are connected by a gear set 304. A servo motor 4 is fixedly connected to the bottom inner wall of the housing 1. The output end of the servo motor 4 is fixedly connected to the bottom end of the input shaft 302. A clutch 5 is fitted on the top of the outer surface of the output shaft 303.

[0026] The clutch 5 includes a rotating sleeve 501 fitted on the outer surface of the output shaft 303. A transmission key 305 is fixedly connected to the outer surface of the output shaft 303. A transmission keyway 502 adapted to the transmission key 305 is opened at the bottom of the inner wall of the rotating sleeve 501. A spline 201 is fixedly connected to the bottom of the outer surface of the rocker rod 2. A rotating spline sleeve 503 is fixedly connected to the upper surface of the rotating sleeve 501. A connecting frame 504 is rotatably connected to the outer surface of the rotating spline sleeve 503. A fixed spline sleeve 505 is rotatably connected to the top of the inner wall of the connecting frame 504. Fixed collars 506 are fixedly connected to both the left and right sides of the outer surface of the fixed spline sleeve 505.

[0027] A fixed post 6, which is fixedly connected to the reducer 3, is slidably inserted into the inner wall of the fixed collar 506. A limit ring 7 is fixedly installed in the middle of the outer surface of the fixed post 6. A spring 8 is installed on the top of the outer surface of the fixed post 6. A drive controller 9, model FX3SA-14MT, is set on the right side of the outer surface of the housing 1. An electromagnetic ring 15 is fixedly installed on the bottom of the outer surface of the fixed post 6. The output end of the drive controller 9 is electrically connected to the servo motor 4 and the input end of the electromagnetic ring 15.

[0028] In this invention, in order to enable the device to block people, a swing column 10 is fitted on the top of the outer surface of the swing column rod 2, and a swing plate 11 is connected to the left side of the outer surface of the swing column 10, so that the swing plate 11 can block people.

[0029] In this utility model, in order to further facilitate the installation of the reducer 3, two sets of support plates 12 are fixedly connected to the bottom of the inner wall of the housing 1, and four sets of fixing bolts 13 are inserted into the bottom of the outer surface of the reducer housing 301. The fixing bolts 13 are threadedly connected to the support plates 12, so that the reducer 3 can be installed on the support plates 12 through the fixing bolts 13, thereby further facilitating the installation of the reducer 3.

[0030] In this invention, in order to further enhance the stability of the fixed column 6, a fixing frame 14 is fixedly connected to the outer surface of the fixed column 6. The outer surface of the fixing frame 14 is fixedly connected to the inner wall of the chassis 1, so that the fixing frame 14 plays a stable supporting role on the top of the fixed column 6, thereby further enhancing the stability of the fixed column 6.

[0031] In this invention, in order to further enhance the stability of the connection between the rotating spline sleeve 503 and the fixed spline sleeve 505 and the connecting frame 504, two sets of annular slide bars are fixedly connected to the outer surfaces of both the rotating spline sleeve 503 and the fixed spline sleeve 505. An annular groove adapted to the annular slide bars is provided on the inner wall of the connecting frame 504. The annular slide bars cooperate with the annular grooves, thereby further enhancing the stability of the connection between the rotating spline sleeve 503 and the fixed spline sleeve 505 and the connecting frame 504.

[0032] In this invention, in order to further enhance the rotational stability of the pendulum rod 2, a ball bearing is provided on the top of the outer surface of the housing 1. The housing 1 is rotatably connected to the pendulum rod 2 through the ball bearing. By providing the ball bearing, the rotational stability of the pendulum rod 2 is further enhanced.

[0033] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0034] In operation, the housing 1 is installed inside the turnstile. When the swing plate 11 needs to be opened, the drive controller 9 starts the servo motor 4. The output end of the servo motor 4 drives the input shaft 302 to rotate. The input shaft 302 drives the output shaft 303 to rotate through the gear set 304. The output shaft 303 drives the rotating sleeve 501 to rotate. At this time, the rotating spline sleeve 503 meshes with the transmission spline 201. The rotating sleeve 501 drives the rotating spline sleeve 503 to rotate. The rotating spline sleeve 503 drives the transmission spline 201 and the swing rod 2 to rotate, thereby driving the swing plate 11 to rotate. When an external force forcibly pushes the swing plate 11, the drive controller 9 determines whether there is an external force by the angle change of the incremental encoder inside the servo motor 4. After detecting the external force... The drive controller 9 activates the electromagnetic ring 15, which attracts the bottom of the rotating sleeve 501, thereby driving the clutch 5 to move downward. The rotating spline sleeve 503 separates from the transmission spline 201, and the servo motor 4 disengages from the transmission system. At the same time, the rotating spline sleeve 503 drives the fixed spline sleeve 505 to move downward through the connecting bracket 504. The fixed spline sleeve 505 engages with the transmission spline 201 and cannot rotate. While engaging with the transmission spline 201, the fixed spline sleeve 505 locks the swing rod 2, and the spring 8 is compressed. When it is necessary to reopen the gate, the drive controller 9 closes the electromagnetic ring 15, the spring 8 resets, the clutch 5 moves upward, and the rotating spline sleeve 503 re-engages with the transmission spline 201.

[0035] In summary, this swing gate mechanism, through the coordinated use of drive controller 9, clutch 5, transmission spline 201, and electromagnetic ring 15, ensures that during normal operation, the rotating spline sleeve 503 engages with the transmission spline 201. When an external force forcibly pushes the swing plate 11, drive controller 9 determines whether an external force is applied by observing the angle change of the incremental encoder inside the servo motor 4. Upon detecting the external force, drive controller 9 activates the electromagnetic ring 15, the clutch 5 moves downward, and the rotating spline sleeve 503 disengages from the transmission spline 201. This allows the servo motor 4 to disengage from the transmission system promptly when an external force forcibly pushes the swing plate 11, further avoiding the risk of over-rotation of the servo motor 4 and extending the service life of the mechanism's servo motor 4.

[0036] The swing gate mechanism, through the coordinated use of a fixed spline sleeve 505, a fixed collar 506, a fixed column 6, and a fixed frame 14, allows the rotating spline sleeve 503 to separate from the transmission spline 201 while simultaneously driving the fixed spline sleeve 505 downwards via the connecting frame 504. The fixed spline sleeve 505 then engages with the transmission spline 201 and is fixedly connected to the fixed collar 506, preventing it from rotating. Simultaneously, the fixed spline sleeve 505 locks the swing column rod 2, thus enabling the device to lock the swing plate 11 immediately upon being forcibly pushed by external force, preventing forced entry by personnel.
