Description

Technical Field

[0001] This utility model relates to the field of barrier gate technology, and in particular to a barrier gate spring hook fixing structure. Background Technology

[0002] A barrier gate, also known as a vehicle barrier, is a specialized access control device used on roads to restrict the movement of motor vehicles. It is widely used in highway toll stations and parking lot systems to manage vehicle entry and exit. Electric barrier gates can be operated independently via wireless remote control, or automatically managed through a parking management system (i.e., an IC card management system). Vehicles enter by taking a card and exit automatically after paying the parking fee. A barrier gate consists of a gearbox, motor, (or hydraulic) transmission mechanism, balancing device, housing, gate arm support, and gate arm.

[0003] Traditional barrier gate spring hooks are fixed to both sides of the bottom of the chassis by welding. However, the welding process itself can cause thermal deformation and changes in the crystal structure of the metal material. Under long-term alternating loads, fatigue cracks are prone to appear at the welded parts. In particular, the frequent start-stop operation of the barrier gate will accelerate the risk of weld cracking. Crack propagation may cause the spring to suddenly fall off and cause a safety accident. Furthermore, the welding fixing method hinders later maintenance. When the spring performance deteriorates, it is necessary to use equipment such as angle grinders to cut the weld points. This is not only time-consuming but also easy to damage the chassis. Re-welding requires professional welders, resulting in high maintenance costs.

[0004] To solve the above problems, this utility model proposes a gate spring hook fixing structure. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model proposes a gate spring hook fixing structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a barrier gate spring hook fixing structure, including a housing, in which a barrier gate motor is fixedly installed. Limiting grooves are provided on both the front and rear sides of the bottom of the housing, and hook fixing plates are movably engaged at both ends of the limiting grooves. Spring hooks are bolted to the upper surface of the hook fixing plates, and springs are provided on the spring hooks. The bottom end of the spring is snapped into the spring hook, and the top end of the spring is fixedly connected to the output shaft of the barrier gate motor through limiting bolts.

[0007] The present invention is further configured such that rectangular sliding grooves are provided on both sides of the inner bottom surface of the chassis, and limit blocks are slidably installed inside the rectangular sliding grooves. The bottom surface of the hook fixing plate is provided with positioning grooves, and the limit blocks are inserted into the positioning grooves.

[0008] The present invention is further configured such that each of the limiting blocks has an inclined surface at its top, and the inclined surface at the top of the limiting block slides in cooperation with the hook fixing plate.

[0009] The present invention is further configured such that a return spring is fixedly connected to the inner bottom surface of the rectangular slide groove, and the other end of the return spring is fixedly connected to the limiting block.

[0010] The present invention is further configured such that through slots are provided on both sides of the chassis, the through slots are connected to the interior of the rectangular sliding groove, and a connecting plate is slidably installed inside the through slot. One end of the connecting plate is fixedly connected to the limiting block, and the other end of the connecting plate extends to the outside of the chassis.

[0011] The present invention is further configured such that a guide groove is provided on the side of the through groove away from the rectangular slide groove, a guide block is slidably installed inside the guide groove, the guide block is fixedly connected to the connecting plate, and an arc-shaped pressure plate is fixedly installed on the end of the connecting plate away from the limiting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This barrier gate spring hook fixing structure consists of a limit groove inside the housing, a hook fixing plate, a limit block with an inclined surface, a return spring, a connecting plate, and a guide mechanism. The operation is as follows: when the hook fixing plate is pushed in along the limit groove, its bottom inclined surface forces the limit block to press down on the return spring. When the positioning groove is aligned, the limit block springs in and locks. During maintenance, pressing the arc-shaped pressure plate moves the limit block down and away from the positioning groove via the connecting plate, allowing the hook fixing plate to be removed. The inclined surface self-locking and spring return mechanism enable quick installation and positioning. During maintenance, only a single-handed pressing operation is needed to unlock the mechanism, eliminating the need for tools to remove the bolts, thus improving spring replacement efficiency and reducing maintenance time and labor costs.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a barrier gate spring hook fixing structure, including a housing 1, in which a barrier gate motor 2 is fixedly installed. Limiting grooves 3 are provided on both the front and rear sides of the bottom of the housing 1. Hook fixing plates 4 are movably engaged at both ends of the limiting grooves 3. This movable engagement design facilitates the disassembly and assembly of the hook fixing plates 4, improving maintenance convenience. Spring hooks 5 are bolted to the upper surface of the hook fixing plates 4. This bolted connection facilitates adjustment and replacement of the spring hooks 5, enhancing structural adjustability.

[0024] Each spring hook 5 is equipped with a spring 6. The bottom end of the spring 6 is snapped to the spring hook 5, and the top end of the spring 6 is fixedly connected to the output shaft of the barrier gate motor 2 by a limit bolt.

[0025] In this embodiment of the invention: Rectangular sliding grooves 7 are provided on both sides of the inner bottom surface of the chassis 1. Limiting blocks 8 are slidably installed inside each rectangular sliding groove 7. Positioning grooves 9 are provided on the bottom surface of each hook fixing plate 4, and the limiting blocks 8 are inserted into the positioning grooves 9. An inclined surface is provided at the top of each limiting block 8, and the inclined surface at the top of the limiting block 8 is slidably engaged with the hook fixing plate 4. A return spring 10 is fixedly connected to the inner bottom surface of the rectangular sliding groove 7, and the other end of the return spring 10 is fixedly connected to the limiting block 8.

[0026] In this embodiment of the invention: Both sides of the chassis 1 are provided with through slots 11, which communicate with the interior of rectangular sliding grooves 7. Connecting plates 12 are slidably installed inside each through slot 11. One end of the connecting plate 12 is fixedly connected to a limiting block 8, and the other end of the connecting plate 12 extends to the outside of the chassis 1. A guide slot 13 is provided on the side of the through slot 11 away from the rectangular sliding groove 7. A guide block 14 is slidably installed inside the guide slot 13, and the guide block 14 is fixedly connected to the connecting plate 12. An arc-shaped pressure plate 15 is fixedly installed on the end of the connecting plate 12 away from the limiting block 8. The guide slot 13 restricts the movement trajectory of the guide block 14, improving operational accuracy, while the guide block 14 enhances the movement stability of the connecting plate 12, preventing deviation.

[0027] Working principle:

[0028] In use, first slide the hook fixing plate 4 into the guide direction of the limiting slide groove 3, ensuring that the side of the hook fixing plate 4 is tightly fitted with the inner wall of the limiting slide groove 3 to avoid tilting or jamming, until the hook fixing plate 4 moves to the end of the limiting slide groove 3. At this time, the bottom inclined surface of the hook fixing plate 4 contacts the top inclined surface of the limiting block 8, and under the continuous pushing action, the limiting block 8 is forced to move downward in the vertical direction, compressing the return spring 10 and completely entering the interior of the rectangular slide groove 7. When the hook fixing plate 4 continues to move forward, so that the positioning groove 9 at its bottom is aligned with the limiting block 8, the elastic restoring force of the return spring 10 drives the limiting block 8 to move upward, so that it is embedded in the positioning groove 9, thereby achieving a stable limit on the hook fixing plate 4, ensuring that the hook fixing plate 4 is reliably locked between the two sides of the limiting slide groove 3, and preventing lateral movement.

[0029] Subsequently, the spring hook 5 is fastened to the upper end of the hook fixing plate 4 with bolts to ensure that there is no gap between the connecting surfaces. Then, the pull ring at the bottom of the spring 6 is tightly engaged with the hook of the spring hook 5. At the same time, the other end of the spring 6 is fixed to the output shaft of the barrier motor 2 with bolts to complete the overall assembly. At this time, the spring 6 is in a pre-stretched state to provide the necessary tension.

[0030] When maintenance or replacement of spring 6 is required, the operator needs to press the arc-shaped pressure plate 15 to drive the connecting plate 12 to move smoothly downward in the vertical direction. At this time, the guide block 14 slides in the guide groove 13 to ensure that the movement trajectory of the limit block 8 is precise and controllable, and to avoid deviation. The downward movement of the connecting plate 12 further drives the limit block 8 to completely disengage from the positioning groove 9, releasing the lock on the hook fixing plate 4. At this time, the hook fixing plate 4 can be slid in the opposite direction along the limit slide groove 3 to remove it, which facilitates the inspection or replacement of spring 6. The whole process does not require disassembling the bolts, which significantly improves maintenance efficiency.

[0031] The self-locking is achieved by the inclined surface of the limiting block 8 and the positioning groove 9, and the elastic reset characteristic of the return spring 10 is used to ensure the reliability of the limit. At the same time, the cooperation between the guide block 14 and the guide groove 13 ensures the stability of the operation process, making installation and maintenance more convenient and precise.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
