Description

Technical Field

[0001] The utility model belongs to the technical field related to swing-type channel gates, and specifically relates to a transmission mechanism for a swing-type channel gate. Background Art

[0002] The channel gate is a common safety device, which is usually used to control the entry and exit of people or vehicles in a certain area. Channel gates can be divided into many types, including revolving gates, swing gates, three-roller gates, etc. These different types of channel gates have their own characteristics and applicable scenarios. The swing gate is generally called a flap gate in the rail transit industry. The shape of its blocking body (gate swing) is a plane with a certain area, perpendicular to the ground, and it blocks and releases by rotating and swinging. The material of the blocking body is commonly made of stainless steel, plexiglass, tempered glass, etc. The power source of the swing channel gate mostly uses a motor, which uses the motor drive to drive the blocking body to rotate and realize the opening and closing action. The motor drive has a response time interval and a slow response speed. The use of the motor drive requires precise control of the motor's rotation angle. Deviations in the angle control will cause the blocking door to not rotate in place, affecting the passage effect. Utility Model Content

DETAILED DESCRIPTION

[0017] like Figures 1 to 3 As shown, the swing-type channel gate transmission mechanism includes a rotating shaft 6 and a channel gate 4. The upper and lower ends of the rotating shaft 6 are both provided with mounting grooves 3, and a fixed locking buckle 5 is arranged in the mounting groove 3. The channel gate 4 and the fixed locking buckle 5 are fixedly connected by screws. An upper supporting connecting sleeve 8 is arranged on the upper end of the rotating shaft 6, and a cylindrical gear 9 is installed on the upper outer side of the upper supporting connecting sleeve 8. The cylindrical gear 9 and the fan gear 11 are meshed with each other, and an articulated connecting seat 16 is installed in the lower rotation connection of the fan gear 11. The articulated connecting seat 16 is connected to the cylinder rod end position of the telescopic cylinder 14. A cylinder fixing seat 15 is arranged on the outer side of the telescopic cylinder 14, and a rotating connecting shaft 19 is arranged on the upper end of the cylinder fixing seat 15. The upper end of the rotating connecting shaft 19 is installed in the cylinder adjusting bearing seat 13, and a fixed connecting seat 12 is fixedly arranged above the cylinder adjusting bearing seat 13 for fixing and installing the power structure of the telescopic cylinder 14.

[0018] Among them, the fixed connecting seat 12 is a F-shaped channel steel structure, and a fixed installation hole is processed on the fixed connecting seat 12. The fixed connecting seat 12 is fixed to the inner wall of the gate channel protection box 20 by bolts, thereby realizing the fixed installation of the cylinder fixing seat 15 and its connecting structure, which is convenient for the maintenance of the power component.

[0019] A reinforcing rib 18 is arranged between the top of the cylinder fixing seat 15 and the outer wall of the rotating connecting shaft 19, and a bearing assembly is arranged between the upper end of the rotating connecting shaft 19 and the cylinder adjusting bearing seat 13 for connection. During the operation of the telescopic cylinder 14, the cylinder fixing seat 15 drives the telescopic cylinder 14 to rotate along the rotating connecting shaft 19. The arrangement of the reinforcing rib 18 can effectively enhance the structural strength of the rotating position of the cylinder fixing seat 15.

[0020] The hinged connecting seat 16 is rotatably connected to the bottom surface of the sector gear 11 through the rotating shaft 17. The center position of the sector gear 11 is connected to the bearing support top seat 10 upward through the rotating rod. The sector gear 11 rotates relative to the bearing support top seat 10. The sector gear 11 and the cylindrical gear 9 are meshed with each other, and the rotating shaft 6 is driven to rotate through the cylindrical gear 9.

[0021] The lower part of the other end of the bearing support top seat 10 is connected to the upper end of the upper support connecting sleeve 8 through a bearing. The lower part of the upper support connecting sleeve 8 is a hollow structure, and the fixed sleeve is installed on the upper end of the rotating shaft 6. The upper part of the upper support connecting sleeve 8 is a solid structure, and a cylindrical gear 9 is installed through a key connection. The setting of the bearing support top seat 10 is used to ensure the stability of the rotation of the rotating shaft 6.

[0022] A snap-in groove 7 is provided on the side of the mounting groove 3, a lower support connecting sleeve 2 is sleeved on the lower end of the rotating shaft 6, a stable support seat 1 is provided below the lower support connecting sleeve 2, and the snap-in groove 7 is used to snap-in the end position of the fixed locking buckle 5 to improve the stability of the installation of the fixed locking buckle 5.

[0023] The edge of the passage gate 4 is covered with protective foam 21, which can effectively provide safety protection and avoid accidental injuries to the elderly and children.

[0024] Working principle: When the gate receives the opening and closing signal and opens the channel gate 4, the cylinder rod of the telescopic cylinder 14 extends, and its lever moves against the articulated connection seat 16. Since the sector gear 11 and the bearing support top seat 10 are rotatably connected, the articulated connection seat 16 rotates relative to the sector gear 11 during the movement of the articulated connection seat 16, and the sector gear 11 rotates relative to the bearing support top seat 10. As the cylinder rod of the telescopic cylinder 14 extends, the cylinder fixing seat 15 will also rotate relative to the cylinder adjustment bearing seat 13. The sector gear 11 and the cylindrical gear 9 are meshed with each other, driving the cylindrical gear 9 to rotate, and the cylindrical gear 9 drives the channel gate 4 to rotate through the rotating shaft 6. Since the telescopic cylinder 14 moves in a straight line with a fast response speed, the novel structure of the present invention is reasonably designed and easy to install and use. The rotation of the channel gate 4 is achieved by the cooperation of the telescopic cylinder 14 and the gear transmission assembly. The telescopic action of the telescopic cylinder 14 can achieve rapid response, and in conjunction with the fan gear 11, the rotation angle of the channel gate 4 can be accurately controlled to ensure that the opening and closing swinging rotation is in place. The telescopic cylinder 14 is fixed to the inner wall of the gate channel protection box 20 through the fixed connecting seat 12, which is convenient for disassembly, assembly and maintenance. The outer edge of the channel gate 4 is covered with a protective foam 21, which can effectively provide safety protection and avoid accidental injuries to the elderly and children.
