Description

Technical Field

[0001] This utility model belongs to the technical field of telescopic gate motor heads, specifically a telescopic gate motor head that is easy to maintain. Background Technology

[0002] Retractable gates, as a common gate structure, are widely used in factories, shopping malls, residential communities, and other places. Their automatic opening and closing function, achieved through a drive unit, greatly improves passage efficiency and convenience. Traditional retractable gate drive units typically consist of a base, a drive unit, and a support unit. The drive unit provides power to move the gate along a predetermined track, while the support unit stabilizes the gate and works with the drive unit to create a passageway for the gate to pass through. However, existing retractable gate drive units have many shortcomings in design and use, particularly in terms of ease of maintenance and overall structural stability.

[0003] First, traditional telescopic gate motor heads often use a one-piece design or fixed connection for the casing, requiring the entire motor head to be disassembled for maintenance or replacement of the internal drive structure. This is complex, time-consuming, and increases maintenance costs. Second, the weight distribution of the drive unit is often unreasonable, making it prone to instability due to a shifted center of gravity, especially after prolonged use, which may lead to shaking or abnormal noises. Furthermore, existing telescopic gate motor heads have relatively simple auxiliary load-bearing structures that cannot effectively distribute the weight of the gate, thus increasing the load on the drive unit and reducing its overall lifespan.

[0004] On the other hand, the existing technology also has certain shortcomings in the arrangement of position sensors and the integration of control systems. Position sensors are usually directly exposed to the external environment and are easily affected by external factors such as dust and rain, which leads to a decrease in detection accuracy. At the same time, the connection between warning devices such as horns and buzzers in the control system and the drive structure is not optimized, the wiring is complex and prone to failure, affecting the reliability of the equipment and the user experience.

[0005] In summary, designing a retractable gate actuator that is easy to maintain, structurally stable, and highly integrated in function has become a pressing technical problem. This invention aims to improve the maintenance convenience, operational stability, and overall performance of the retractable gate actuator by enhancing the drive unit, housing structure, and auxiliary load-bearing structure, thereby meeting diverse needs in practical applications.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] Example 1: This embodiment provides a telescopic gate motor head that is easy to maintain, and has the following technical features.

[0030] Please see Figure 1-5A retractable gate motor that is easy to maintain includes a base 11, a drive unit and a support unit 12. The drive unit and the support unit 12 are fixedly mounted on the base 11 by bolts, and a space for the retractable gate to pass through is formed between them.

[0031] The base 11 has an inverted L-shaped fixing plate 29 on the side away from the support part 12 and the drive part. The fixing plate 29 has multiple bolt holes, and the base 11 is firmly fixed to the ground by bolts, thereby ensuring the stability of the entire telescopic gate motor during operation.

[0032] The base 11 is made of high-strength steel and has been treated with anti-rust coating, so it can be used for a long time in various environments without being easily damaged.

[0033] The drive unit includes a housing, a drive structure, and a counterweight 13. The housing consists of a fixed shell 14 and a shielding panel 15. The fixed shell 14 is a box-shaped structure with an opening on one side, and its interior is used to house the drive structure and other functional components.

[0034] The shielding panel 15 is detachably mounted to the opening of the fixed housing 14 by bolts. When maintenance or repair of the drive unit is required, the shielding panel 15 can be quickly removed by simply loosening the bolts, thus facilitating the operation of internal components by technicians. This design not only simplifies the maintenance process but also significantly reduces maintenance time and costs.

[0035] Both the mounting shell 14 and the shielding panel 15 are made of corrosion-resistant materials, which can effectively resist the influence of external environmental factors and extend their service life.

[0036] The drive structure is installed inside the housing and includes a frame 16, a motor 17, and a reducer 18. The frame 16 is fixed inside the fixed housing 14 by bolts, and its main function is to provide a stable mounting platform for the motor 17 and the reducer 18. The motor 17 is mounted on the frame 16, and its output end is inserted into the reducer 18, through which power is output to the outside.

[0037] The output end of the reducer 18 passes through the housing and extends into the receiving space, connecting with the transmission mechanism to drive the telescopic gate to move along a predetermined track. The transmission mechanism can be either chain drive or gear drive, with the appropriate transmission method selected based on actual needs.

[0038] The reducer 18 is designed to convert the high-speed rotation of the motor 17 into a low-speed, high-torque output, thereby meeting the driving force requirements for the operation of the telescopic gate. Furthermore, the output end of the reducer 18 and the transmission mechanism employ a keyway fit to ensure precise and efficient power transmission.

[0039] The counterweight 13 is installed inside the housing and located below the drive structure to increase the overall weight of the drive unit, thereby improving the stability and anti-tipping ability of the equipment during operation. The counterweight 13 is fixed to the base 11 by bolts, and a load-bearing space is formed between the support plate 24 and the base 11. The counterweight 13 is located in the load-bearing space and is detachably connected to the base 11.

[0040] This design makes the installation and adjustment of the counterweight 13 more convenient. Users can increase or decrease the number of counterweights 13 according to actual needs to achieve the best balance. For example, in windy environments, the weight of the counterweight 13 can be increased to enhance the equipment's anti-overturning ability; while in situations where the ground bearing capacity is limited, the weight of the counterweight 13 can be appropriately reduced to decrease the pressure on the ground.

[0041] The drive unit's housing also houses a control structure, including a control box 25, a horn 26, and a buzzer 27. The control box 25 is bolted to the inside of the fixed housing 14 and contains a control circuit board for intelligent control of the entire telescopic gate mechanism. The control circuit board is connected to the horn 26, buzzer 27, motor 17, and position sensor 23 via wires, thereby enabling audible alerts, alarm signal output, and precise displacement control of the telescopic gate.

[0042] Position sensor 23 is mounted on frame 16, with one end penetrating the housing and working in conjunction with the telescopic gate within the housing space. Position sensor 23 can detect the position information of the telescopic gate in real time and feed the data back to the control circuit board, thereby achieving precise control of the telescopic gate's displacement. For example, when the telescopic gate reaches a preset position, position sensor 23 sends a signal to the control circuit board, which then stops the operation of motor 17, thus preventing the telescopic gate from exceeding the predetermined range.

[0043] The accommodating space is equipped with an auxiliary load-bearing structure, the specific structure of which is as follows: Figure 3 As shown. The auxiliary support structure includes a support plate 19, a fixing plate 20, and rollers. The support plate 19 is fixedly connected to the base 11 via the fixing plate 20, providing auxiliary support for the lower part of the telescopic gate.

[0044] The rollers are mounted on the support plate 19 and contact the lower part of the telescopic gate. The rollers include a support roller 21 and an auxiliary roller 22. The outer edge of the support roller 21 is projected onto the base 11 parallel to the base 11, providing support for the main load. The outer edge of the auxiliary roller 22 is perpendicular to the base 11, assisting in guidance and distributing lateral forces, thus ensuring smoother and more stable movement of the telescopic gate. Both the support roller 21 and the auxiliary roller 22 are made of high-strength, wear-resistant rubber, effectively reducing friction and vibration, and extending the service life of the equipment.

[0045] In addition, the installation position and number of rollers can be adjusted according to the actual size and weight of the sliding gate to meet the usage needs in different scenarios.

[0046] The support part 12 is arranged parallel to the drive part and is fixed to the base 11 by bolts. The upper end of the support part 12 is connected to the drive part through the connecting plate 28. The connecting plate 28 is parallel to the base 11, thereby ensuring the symmetry and stability of the overall structure.

[0047] The two ends of the connecting plate 28 are fixedly connected to the support part 12 and the drive part by bolts, respectively. A reinforcing rib can be added to the middle of the connecting plate 28 to enhance its bending resistance and overall rigidity.

[0048] The connecting plate 28 is made of high-strength aluminum alloy, which ensures structural strength while reducing overall weight, making it easy to transport and install.

[0049] The operating principle of this utility model is as follows: After S1 starts the motor 17, the output end of the motor 17 drives the reducer 18 to run. The reducer 18 converts the high-speed rotation into low-speed, high-torque output, and transmits the power to the telescopic gate through the transmission mechanism, so that the telescopic gate moves along the predetermined track.

[0050] During the movement of the telescopic gate, the position sensor 23 detects the position information of the telescopic gate in real time and feeds the data back to the control circuit board. The control circuit board controls the start and stop of the motor 17 according to the preset program, thereby realizing precise control of the displacement of the telescopic gate.

[0051] When the sliding gate reaches the preset position, the position sensor 23 sends a signal to the control circuit board, which then stops the operation of the motor 17 and simultaneously emits a prompt sound through the horn 26 or buzzer 27 to remind the user that the sliding gate has reached the designated position.

[0052] Throughout the operation of the S4, the support wheel 21 and auxiliary wheel 22 in the auxiliary load-bearing structure provide stable support and guidance for the telescopic gate, effectively reducing friction and vibration, and ensuring smooth operation of the telescopic gate.

[0053] This invention is applicable to various types of retractable gate systems, and is especially suitable for use in commercial buildings, industrial parks, and other similar locations. Its modular design and optimized functional configuration significantly improve the maintainability, operational stability, and overall structural stability of the equipment, giving it high practical value and promising market prospects.

[0054] This easy-to-maintain telescopic gate motor head adopts a combination shell of "fixed shell 14 and detachable shielding panel 15" and a modular bolt fixing design (the drive structure, counterweight 13, and control box 25 are all bolted together), which solves the problems of traditional integrated shell motor heads requiring disassembly of the entire machine for maintenance, complicated and time-consuming operation, high maintenance costs, and easily damaged parts.

[0055] This easy-to-maintain telescopic gate motor head adopts a keyway structure with a flexibly adjustable counterweight 13, a reinforced aluminum alloy connecting plate 28, a steel rust-proof base 11 (with an inverted L-shaped multi-point fixing plate 29), and a reducer 18. This solves the problems of uneven weight distribution in traditional motor heads leading to center of gravity shift, shaking and abnormal noise, easy overturning, and easy deformation of the support part 12 connection.

[0056] This easy-to-maintain telescopic gate motor head adopts a combined roller structure consisting of a bearing plate 19, a fixing plate 20, a support wheel 21 (bearing vertical weight), and an auxiliary wheel 22 (resisting lateral force) (the rollers are made of wear-resistant rubber). This solves the problems of traditional motor heads having simple auxiliary bearing, high load on the drive unit causing the motor 17 to overheat, rapid wear of the reducer 18, and easy jamming of the gate.
