Description

Technical Field

[0001] This utility model relates to the field of three-pole gate technology, and in particular to a three-pole gate mechanism. Background Technology

[0002] Triple turnstiles play a crucial role in personnel access management and security control. As the core component of a triple turnstile, the performance of its mechanism directly impacts its operational efficiency and security. A reliable and efficient triple turnstile mechanism is essential for achieving precise personnel control and security.

[0003] In existing technologies, the three-pole brake mechanism typically employs traditional mechanical transmission and control methods. Generally, a motor drives a gear set or belt drive to rotate the three-pole brake lever. In terms of controlling the direction of rotation, either a mechanical limit device or a complex circuit is used to control the forward and reverse rotation of the motor to achieve a certain degree of directional control.

[0004] Existing tripod turnstile mechanisms often fail to achieve reliable locking when precise locking of the bearing ring's rotation direction is required. This can lead to accidental rotation or insecure locking, affecting the normal use and safety performance of the tripod turnstile. Therefore, a new tripod turnstile mechanism is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a three-roller gate mechanism, which aims to improve the existing three-roller gate mechanism, which often fails to achieve a reliable locking effect when the rotation direction of the bearing ring needs to be precisely locked, and may result in mis-rotation or insecure locking, affecting the normal use and safety performance of the three-roller gate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A three-roller brake mechanism includes a mounting plate, a mounting base two fixedly connected to the upper surface of the mounting plate, a brake fixedly connected to the upper surface of the mounting base two, a rotating shaft rotatably connected inside the brake, a gear one fixedly connected to the side wall of the rotating shaft, a one-way bearing fixedly connected to the side wall of the rotating shaft, a bearing sleeve fixedly connected to the side wall of the one-way bearing, and a brake plate fixedly connected to the lower surface of the bearing sleeve.

[0014] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] In this invention, by energizing the brake, the brake plate is attracted, thereby fixing the outer ring of the one-way bearing with the bearing sleeve, so that the one-way bearing can only rotate in one direction, and the shaft can only rotate in one direction, thus achieving the effect of locking the rotation direction of the bearing ring.

[0027] 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.

[0028] Reference Figures 1-3 This utility model provides an embodiment of a triple brake mechanism, including a mounting plate 1. A mounting base 2 5 is fixedly connected to the upper surface of the mounting plate 1. A brake 6 is fixedly connected to the upper surface of the mounting base 2 5. The brake 6 is an important component of the triple brake mechanism, capable of quickly braking the rotation of the rotating shaft 10 when needed, thereby controlling the triple brake. The rotating shaft 10 is rotatably connected inside the brake 6. The rotating shaft 10 is a key component for transmitting power and realizing the rotation of the triple brake. A gear 11 is fixedly connected to the side wall of the rotating shaft 10, and the gear 11 meshes with a gear 2 13. The power of the motor 3 is transmitted to the bearing ring 4 through gear transmission, thereby realizing the rotation of the tripod brake. A one-way bearing 8 is fixedly connected to the side wall of the rotating shaft 10. The one-way bearing 8 can control the rotation direction of the rotating shaft 10, allowing it to rotate freely in only one direction, while locking it in the other direction. It provides a guarantee for the one-way rotation of the tripod brake, ensuring that the tripod brake can only rotate in the predetermined direction when working normally, preventing the safety hazards caused by reverse rotation. A bearing sleeve 7 is fixedly connected to the side wall of the one-way bearing 8, which provides installation and protection for the one-way bearing 8. A brake plate 9 is fixedly connected to the lower surface of the bearing sleeve 7. The brake plate 9 fits against the brake 6. When the brake 6 is working, the brake plate 9 acts to brake the rotating shaft 10. The brake plate 9 has good wear resistance and braking performance, ensuring sufficient friction during braking to quickly stop the rotation of the rotating shaft 10. The side wall of the bearing sleeve 7 is rotatably connected to the inside of the brake 6. This connection method allows the bearing sleeve 7 to rotate freely inside the brake 6, while also ensuring a tight fit with the brake 6 during braking to achieve effective braking. (The last sentence appears to be incomplete and possibly refers to a different part of the mounting plate 1.) Mounting base 11 is fixedly connected to the surface. Motor 3 is fixedly connected to the upper surface of mounting base 11. Gear 314 is fixedly connected to the output end of motor 3. Gear 314 meshes with gear 213. Encoder 12 is set on the upper surface of mounting plate 1. Bearing ring 4 is set inside encoder 12. The side wall of bearing ring 4 is rotatably connected to the inside of mounting plate 1. Gear 213 is fixedly connected to the side wall of bearing ring 4. Gear 11 meshes with gear 213. Gear 314 meshes with gear 213. Power transmission of motor 3 is realized through gear transmission to ensure the normal operation of the three-roller brake mechanism.

[0029] When using this device, first start motor 3. Once motor 3 starts, it will drive the connected gear 14 to rotate. Since gear 14 and gear 13 are meshed, the rotation of gear 14 will cause gear 13 to rotate. Gear 13 plays the role of transmitting power in this process, transmitting the rotation from gear 14 to the connected bearing ring 4, thereby driving the tripod brake to rotate. During this rotation, when the left brake 6 is energized, brake 6 will generate magnetic force, and brake 6 can... A strong magnetic force is generated when electricity is applied, which attracts the brake plate 9. Once the brake plate 9 is attracted, the bearing sleeve 7 connected to it is fixed. When the bearing sleeve 7 is fixed, the outer ring of the one-way bearing 8 inside it is also fixed and cannot rotate freely. The one-way bearing 8 has special characteristics and can only rotate in one specific direction. In this situation, since gear 11 and gear 2 13 are meshed with each other, and the rotation of the bearing ring 4 is related to gear 2 13, and is also affected by the fixed outer ring of the one-way bearing 8 and its one-way rotation characteristic, the bearing... Ring 4 can only rotate clockwise along the rotation direction of the one-way bearing 8. Similarly, when the right brake 6 is energized, it generates a magnetic force. This strong magnetic force attracts the brake plate 9. Once the brake plate 9 is attracted, the connected bearing sleeve 7 is fixed. When the bearing sleeve 7 is fixed, the outer ring of the one-way bearing 8 inside it is fixed and cannot rotate freely. The one-way bearing 8 has special characteristics, allowing it to rotate only in a specific direction. In this situation… Since gear 11 and gear 2 13 are meshed with each other, and the rotation of bearing ring 4 is related to gear 2 13, and is also affected by the fixed outer ring of one-way bearing 8 and its one-way rotation characteristics, bearing ring 4 can only rotate counterclockwise along the rotation direction of one-way bearing 8. When both brakes 6 are locked, the magnetic force generated by brake 6 firmly attracts brake plate 9, so that bearing sleeve 7 and outer ring of one-way bearing 8 are completely fixed. At this time, the tripod brake will be in a locked state and cannot be rotated, ensuring the safety and stability of tripod brake under specific conditions.

[0030] Working principle: When the device is in operation, starting the motor 3 causes the gear 14 to rotate, which in turn drives the meshing gear 13 to rotate, thereby causing the bearing ring 4 to rotate and driving the tripod brake to rotate. During the rotation, the brake 6 can be energized to hold the brake plate 9, thereby fixing the bearing sleeve 7 and fixing the outer ring of the one-way bearing 8 so that it cannot rotate freely. Through the characteristics of the one-way bearing 8, it can only rotate in one direction, thereby achieving the effect of controlling the rotation direction of the tripod brake.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
