Description

Technical Field

[0001] This utility model relates to the field of turbine high-speed door technology, and in particular to a turbine high-speed door and its counterweight mechanism. Background Technology

[0002] The turbine high-speed door consists of a mechanical structure composed of a door panel and a door frame, a drive mechanism, a control mechanism, a safety protection mechanism, and a counterweight mechanism. The counterweight mechanism of existing turbine high-speed doors generally adopts the spring counterweight method or the counterweight block counterweight method. Among them, the spring counterweight method uses the elastic force of the spiral tension spring to balance the weight of the garage door panel. Through the process of "spring tension-energy storage-energy release", it coordinates with the movement trajectory of the door panel. For example, when the door panel moves from the closed state to the fully open direction, the spring gradually releases the elastic potential energy, and the tension decreases as the tension decreases. However, the spring counterweight method has the following problems: (1) The spring will become fatigued after long-term use, resulting in a decrease in elasticity. It needs to be checked regularly (e.g., once a year). If the spring breaks, it needs to be replaced immediately, otherwise the door panel will be at risk of losing control; (2) The spring will collide and generate noise when the door panel is running, resulting in a poor user experience; (3) When the power is off, the door can only be opened in an emergency, but it is difficult to close, resulting in inconvenience.

[0003] Current counterweight methods apply the counterweight force directly to the door panel roller, as in existing technologies 202021600280.7 and 201220625541.X. However, this existing counterweight mechanism fails to prevent the door panel from falling if the chain connecting the roller to the door panel breaks; furthermore, it requires extending the roller's length, making installation inconvenient and costly.

[0004] Therefore, it is evident that the existing counterweight mechanisms of turbine high-speed doors still have inconveniences and defects in terms of structure, method, and use, and urgently need further improvement. How to create a new turbine high-speed door and its counterweight mechanism that can easily and conveniently balance the weight of the garage door panel, with low noise, maintenance-free operation, manual opening and closing of the door panel during power outages, good anti-fall performance, small footprint, and aesthetic and safety features has become a pressing goal for the industry. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a counterweight mechanism for a turbine high-speed door, which can easily and conveniently balance the weight of the garage door panel, with low noise, no maintenance, manual opening and closing of the door panel during power outages, good anti-fall effect of the door panel, small space occupation, and beautiful and safe appearance, thereby overcoming the shortcomings of the existing counterweight mechanism of turbine high-speed door.

[0006] To solve the above-mentioned technical problems, this utility model provides a counterweight mechanism for a turbine high-speed door. The turbine high-speed door includes a door beam and doorposts disposed on both sides thereon, as well as a door panel and a drive mechanism for driving the door panel to open and close. The counterweight mechanism includes a counterweight block, a steel wire rope, a pulley block, and a fixed hanging block. The counterweight block is slidably disposed inside the doorposts. The pulley block is disposed on the upper part of the doorposts. One end of the steel wire rope is connected to the counterweight block, and the other end of the steel wire rope passes around the pulley block and is connected to the fixed hanging block. The fixed hanging block is also fixedly connected to the bottom of the door panel. The counterweight block moves up and down in the opposite direction to the door panel when the door panel is opened and closed.

[0007] In a further improvement, the counterweight mechanism also includes a slide rail and a slider disposed therein, the slide rail being vertically disposed inside the doorpost, and the slider being fixedly connected to the counterweight block.

[0008] As a further improvement, the slider is made of self-lubricating nylon.

[0009] In a further improvement, the slide rail adopts a C-shaped guide rail, and the slider adopts a convex-shaped structure that matches the C-shaped guide rail.

[0010] In a further improvement, the slide rail includes at least two sliders, which are respectively connected to the upper and lower ends of the counterweight.

[0011] In a further improvement, the counterweight adopts a split structure consisting of multiple cuboid structures connected in parallel, with the multiple cuboid structures fixedly connected by bolts, wherein the innermost cuboid structure is fixedly connected to the slider.

[0012] As a further improvement of this utility model, this utility model also provides a turbine high-speed door. The turbine high-speed door includes the counterweight mechanism of the aforementioned turbine high-speed door.

[0013] In a further improvement, the turbine-style high-speed door includes two symmetrically arranged counterweight mechanisms, and the total weight of the counterweight blocks in the two counterweight mechanisms is equal to the weight of the door panel.

[0014] With this design, the present invention has at least the following advantages:

[0015] 1. The counterweight mechanism of this utility model turbine high-speed door, by setting the counterweight block in the door post and connecting it to the bottom of the door panel with a steel wire rope and pulley system, allows the counterweight to act directly on the door panel instead of on the door panel roller. This enables the door panel drive mechanism to be driven by a small motor, which requires less power, is more energy-efficient, and has a lower cost. It also avoids the need to extend the door panel roller, making it convenient and quick to improve existing turbine high-speed doors, with low upgrade costs.

[0016] 2. Furthermore, the cooperation between the slider and the slide rail, along with the selection of self-lubricating nylon sliders, ensures noiseless movement and smoother operation of the counterweight. This configuration has a simple structure, requires no maintenance, and greatly reduces unnecessary maintenance costs.

[0017] 3. The split structure of the counterweight allows for easy adjustment of its mass to suit different door panel requirements. It easily meets the requirement of a 1:1 weight ratio between the counterweight and the door panel, and also allows the door panel to be manually opened and closed after a power outage, making it flexible and convenient.

[0018] 4. Furthermore, since the door panel is connected to the counterweight via steel wire rope, even if the door panel drive chain breaks simultaneously, the door panel will not suddenly fall, providing a good anti-fall effect and ensuring safety and reliability.

[0019] 5. The counterweight mechanism of this utility model occupies little space, and the improved turbine high-speed door has a beautiful overall visual effect and a better user experience. Attached Figure Description

[0020] The above is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model, the following describes this utility model in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Figure 1 This is a schematic diagram of the counterweight mechanism of the turbine high-speed door of this utility model.

[0022] Figure 2 This is a partial structural diagram of the counterweight mechanism of the turbine high-speed door of this utility model (counterweight block removed).

[0023] Figure 3 This is a schematic diagram of the slide rail and slider in the counterweight mechanism of the turbine high-speed door of this utility model. Detailed Implementation

[0024] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0025] The improved counterweight mechanism of this invention is used in a turbine high-speed door, as shown in the attached figure. Figure 1 As shown, the turbine high-speed door includes a door beam 1 and door posts 2 disposed on both sides thereon, as well as a door panel 3 and a drive mechanism 4 for moving the door panel 3. It should be noted that the door beam, door panel and drive mechanism all adopt existing turbine high-speed door structures, and this application does not limit them.

[0026] The counterweight mechanism described in this embodiment includes a counterweight block 11, a wire rope 12, a pulley block 13, and a fixed lifting block 14. (See attached diagram) Figure 1 As shown, the counterweight 11 is slidably disposed inside the doorpost 2, the pulley assembly 13 is disposed on the upper part of the doorpost 2, one end of the steel wire rope 12 is connected to the counterweight 11, and the other end of the steel wire rope 12 passes through the pulley assembly 13 and is connected to the fixed hanging block 14. The fixed hanging block 14 is also fixedly connected to the bottom of the door panel 3. Therefore, when the door panel 3 is opened and closed, the counterweight 11 moves up and down in the opposite direction to the door panel 3; for example, when the door panel 3 rises, the counterweight 11 falls, and when the door panel 3 falls, the counterweight 11 rises. That is, the counterweight 11 can provide a reverse torque to the door panel, forming a weight balance between the counterweight 11 and the door panel 3.

[0027] The better ones are as follows: Figure 2 As shown in Figure 3, the counterweight mechanism in this embodiment further includes a slide rail 15 and a slider 16 disposed therein. The slide rail 15 is vertically disposed inside the doorpost 2, and the slider 16 is fixedly connected to the counterweight block 11 to ensure the vertical movement of the counterweight block.

[0028] The slider 16 is made of self-lubricating nylon, which ensures that the counterweight moves without noise and runs more smoothly.

[0029] For details, see attached. Figure 3 As shown, the slide rail 15 adopts a C-shaped guide rail, and the slider 16 adopts a convex-shaped structure that matches the C-shaped guide rail. More preferably, the slide rail 15 includes at least two sliders 16, and the two sliders 16 are respectively connected to the upper and lower ends of the counterweight 11 to ensure that the counterweight does not sway left and right.

[0030] In this embodiment, the counterweight 11 adopts a split structure consisting of multiple cuboid structures connected in parallel. This allows the amount of counterweight to be adjusted according to the weight of the door panel, providing flexibility and convenience. More specifically, the multiple cuboid structures are all fixedly connected by bolts, facilitating disassembly and installation. The innermost cuboid structure is fixedly connected to the slider 16.

[0031] When using the aforementioned counterweight mechanism for existing turbine high-speed doors, only the existing doorposts need to be modified, which is simple and convenient.

[0032] To ensure the effective counterweighting of the counterweight mechanism, each of the doorposts 2 on both sides of the turbine high-speed door includes a counterweight mechanism, and the two counterweight mechanisms are symmetrically arranged. Furthermore, the total weight of the counterweight blocks 11 in the two counterweight mechanisms is equal to the weight of the door panel 3, forming a 1:1 ratio between the counterweight and the door panel weight. This allows the door panel drive mechanism 4 to be driven by a small motor, requiring less power, resulting in greater energy efficiency and lower cost.

[0033] This utility model's counterweight mechanism is simple in structure, low in cost, maintenance-free, noiseless, and operates more smoothly. Because the counterweight and door panel weight are in a 1:1 ratio, the garage door opens and closes faster, and the door can be manually opened and closed during a power outage. Furthermore, since the door panel is connected to the counterweight via steel cables, the force of the counterweight mechanism is actually applied to the door panel. Even if the transmission chain between the drive mechanism and the door panel breaks simultaneously, the door panel will not fall directly, providing excellent anti-fall performance.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the above-disclosed technical content shall fall within the protection scope of the present utility model.
