Description

Technical Field

[0001] This utility model relates to the field of gate technology, specifically to a high-speed gate mechanism. Background Technology

[0002] A turnstile is a channel blocking device (channel management equipment) widely used in urban rail transit management to manage pedestrian flow and regulate pedestrian access. It is mainly used in subway turnstile systems and fare collection turnstile systems, thus creating paid and non-paid areas. Its most basic and core function is to allow only one person to pass through at a time, and it can be used at entrances in various paid and access control situations.

[0003] With the rapid pace of urban construction, gate barriers are being installed at the entrances of various residential communities to facilitate the management of people and vehicles entering and exiting. Traditional gate barriers create lane obstructions with raised and lowerable bars, controlled by license plate recognition or ETC cards, among other methods. However, with societal development and the increasing number of vehicles passing through various entrances and exits, there is a growing need for gate barriers with longer lifespans and faster raising and lowering speeds to meet on-site operational demands.

[0004] The current gate mechanisms have the following defects and shortcomings: the existing brushless gate mechanism has a slow lifting speed, which affects the working efficiency and cannot meet the needs of entrances and exits with high vehicle flow, such as highway toll stations and large shopping malls, which can easily cause congestion; moreover, the existing high-speed gate mechanism has a complex structure and high manufacturing and maintenance costs, thus failing to meet the market demand for civilian use. Utility Model Content

[0005] Based on this, the present invention provides a high-speed barrier gate mechanism to solve the technical problem of slow lifting speed of the barrier gate arm with simple structure in the prior art.

[0006] To achieve the above objectives, this utility model provides a high-speed barrier gate mechanism, which includes:

[0007] Movement mounting plate;

[0008] The main shaft is rotatably mounted on the mechanism mounting plate via a bearing housing, and a main drive arm and a balance arm are fixedly connected to the main shaft.

[0009] A tension spring, one end of which is connected to the balance arm, and the other end which is away from the movement mounting plate and fixed relative to the movement mounting plate;

[0010] A motor is fixedly mounted relative to the mechanism mounting plate. A motor drive arm is fixedly connected to the motor shaft. The end of the motor drive arm away from the motor and the end of the main drive arm away from the main shaft are both connected to the two ends of the connecting arm via a shaft-hinged connection structure. A servo motor is preferred.

[0011] The gate arm is fixedly connected to the main shaft. When the motor drives the motor shaft to rotate, the main shaft is driven to rotate through the transmission cooperation of the motor drive arm, connecting arm and main drive arm, thereby driving the gate arm to rotate. During the gate arm raising process, the tension spring provides elastic tension to assist the main shaft to rotate.

[0012] As a further preferred technical solution of this utility model, it also includes a fixed bracket, wherein the movement mounting plate is fixedly installed on the top of the fixed bracket.

[0013] As a further preferred embodiment of this invention, the end of the tension spring furthest from the movement mounting plate is fixed to the fixed bracket, and the position on the fixed bracket for fixing the tension spring relative to the movement mounting plate is adjustable. The fixed bracket has multiple pin holes arranged at different distances from the movement mounting plate. The end of the tension spring is locked in place by inserting a pin into one of these pin holes. By changing the position of the pin inserted into different pin holes, the preload of the tension spring can be adjusted.

[0014] As a further preferred embodiment of this invention, the mounting distance of the tension spring on the balance arm relative to the main shaft is adjustable. The position on the balance arm for fixing the tension spring is also configured as a pin hole, and the tension spring is fixed to the balance arm through the engagement of the pin hole and a latch. Similarly, there are multiple pin holes, each set at a different distance from the main shaft, thereby adjusting the mounting position of the tension spring on the balance arm.

[0015] As a further preferred embodiment of this utility model, the tension springs are multiple, and the multiple tension springs are arranged in parallel. More preferably, two tension springs are arranged in parallel.

[0016] As a further preferred technical solution of this utility model, the motor is mounted on the core mounting plate by a motor mounting bracket, and the front end of the motor shaft is connected to a motor shaft mounting seat fixed on the core mounting plate.

[0017] As a further preferred technical solution of this utility model, the motor fixing frame is provided with a limiting block for limiting the rotation angle of the motor drive arm with the motor shaft.

[0018] As a further preferred technical solution of this utility model, the end of the motor drive arm away from the motor and the end of the main drive arm away from the main shaft are both provided with bearings, and the two ends of the connecting arm are respectively provided with connecting shafts, and the connecting shafts cooperate with the bearings to form a shaft rotation hinge connection.

[0019] As a further preferred technical solution of this utility model, clearance positions are respectively opened in the areas corresponding to the main drive arm and the balance arm on the mechanism mounting plate.

[0020] The high-speed barrier gate mechanism of this utility model, by adopting the above-mentioned technical solution, can achieve the following beneficial effects:

[0021] 1) The high-speed barrier gate mechanism of this utility model uses a tension spring to provide action and reaction forces during the raising / lowering of the gate arm, which ensures the smooth operation of the gate arm, thereby increasing its service life and reducing maintenance costs; moreover, the smooth operation reduces operating noise and improves the user experience.

[0022] 2) The high-speed barrier gate mechanism of this utility model uses a tension spring to provide force during the lifting process, which enables the barrier arm to rise and fall quickly, up to 0.3 seconds, thereby ensuring the passage efficiency of the barrier.

[0023] 3) The working cycle angle of the entire linkage mechanism (transmission coordination of the motor drive arm, connecting arm, and main drive arm) of this utility model high-speed barrier gate core can be flexibly set according to the limit block. For example, if it is set to 90 degrees, the mechanism only needs to rotate 90 degrees from the starting position to the landing position to complete the work. Similarly, the main shaft also rotates 90 degrees accordingly, thereby improving the gate arm raising and lowering speed. In actual use, the working cycle angle of the linkage mechanism can be set to 30 to 180 degrees as needed, such as 30, 45, 60, 90, 120 degrees, etc. Attached Figure Description

[0030] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Terms such as "upper," "lower," "left," "right," "middle," and "one" used in the preferred embodiments are merely for clarity of description and are not intended to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of the present invention.

[0032] like Figures 1 to 4 As shown, this utility model provides a high-speed barrier gate mechanism, comprising:

[0033] Fixed bracket 7;

[0034] The mechanism mounting plate 1 is fixed to the top of the fixed bracket 7 to serve as a support platform for the transmission part of the barrier gate mechanism;

[0035] The main shaft 16 is rotatably mounted on the mechanism mounting plate 1 via two bearing seats 4. The main shaft 16 is fixedly connected with a separately arranged main drive arm 2 and a balance arm 13.

[0036] The tension spring 14 has one end fixedly connected to the balance arm 13 away from the main shaft 16 by a rotatable pin, and the other end fixedly connected to the fixed bracket 7 away from the movement mounting plate 1 by a rotatable pin. The fixed bracket 7 and the balance arm 13 are respectively provided with pin holes 11 for matching pins; two tension springs 14 are arranged in parallel.

[0037] Motor 10 is mounted on the mechanism mounting plate 1 via motor mounting bracket 9. The front end of the motor shaft of motor 10 is also connected to a motor shaft fixing seat 15 fixed on the mechanism mounting plate 1. The motor mounting bracket 9 and the motor shaft fixing seat 15 work together to stably fix motor 10 relative to the mechanism mounting plate 1, ensuring operational stability. A motor drive arm 6 is fixedly connected to the motor shaft. The motor drive arm 6 is connected to the main drive arm 2 via a connecting arm 5. Bearings are provided at both ends of the motor drive arm 6 away from the motor 10 and at both ends of the main drive arm 2 away from the main shaft 16. Connecting shafts 3 are provided at both ends of the connecting arm 5, and the connecting shafts 3 cooperate with the bearings for a hinged connection.

[0038] The gate arm 12 is fixedly connected to the main shaft 16. When the motor 10 drives the motor shaft to rotate, the main shaft 16 is driven to rotate by the planar folding of the motor drive arm 6, the connecting arm 5 and the main drive arm 2. This drives the gate arm 12 to rotate, that is, the gate arm 12 is raised and lowered by the forward and reverse rotation of the motor 10.

[0039] In order to achieve rapid lever raising, the tension spring 14 is configured via the balance arm 13 to provide force when the lever 12 is in the lever raising state (e.g., Figure 1 When the lever 12 is stretched to its maximum, the tension spring 14 provides elastic tension to assist the main shaft 16 in rotating during the lever raising process, thereby increasing the lever raising speed; conversely, during the screwing process, the weight of the lever 12 and the torsional force generated by the motor 10 cause the lever 12 to descend rapidly into the lowered state (e.g., when the lever is stretched to its maximum). Figure 2 During this process, the tension spring 14 provides a reaction force, thereby ensuring the smoothness of the movement and effectively reducing mechanical impact, thus avoiding equipment damage.

[0040] To ensure precise raising and lowering positions of the gate arm 12, the motor mounting bracket 9 is equipped with a limit block 8 of an arc structure to restrict the angle of rotation of the motor drive arm 6 with the motor shaft. Both ends of the limit block 8 can stop the motor drive arm 6. For example, when the motor drive arm 6 rotates counterclockwise until it contacts the limit block 8 and forms a block, the gate arm 12 is raised at 90 degrees; when the motor drive arm 6 rotates clockwise until it contacts the limit block 8 and forms a block, the gate arm 12 is lowered at 90 degrees.

[0041] Although specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and various changes or modifications can be made to these embodiments without departing from the principles and essence of the present invention. The scope of protection of the present invention is defined only by the appended claims.
