Abstract
Description
Technical Field
[0001] This utility model relates to the field of suspended door technology, and in particular to an intelligent sensor-activated energy-saving suspended door. Background Technology
[0002] A cantilever gate is a security measure, a device used to stop vehicles, primarily used at railway crossings, industrial parks, factories, and residential areas. Existing cantilever gates utilize casters mounted on fixed gate arms, allowing the gate to slide along these casters.
[0003] During the sliding process, the suspended gate experiences uneven force due to its own weight, causing instability. If a gust of wind blows from the side, the suspended gate may sway, making it impossible to enter the gatepost and affecting its use. To address this technical problem, this application proposes an intelligent sensor-based energy-saving suspended gate. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an intelligent, energy-saving, suspended gate. During the movement of the lower beam, the support wheels are always attached to the upper and lower sides of the inner wall of the lower beam, limiting the vertical direction of the lower beam and supporting it in conjunction with the rear support wheels to prevent the suspended gate from becoming unstable due to its own weight. At the same time, the limiting wheel group also limits the horizontal direction of the suspended gate to prevent it from shaking due to strong winds and being unable to enter the gatepost.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A smart, energy-saving, suspended gate includes a gantry frame and gateposts. The bottom of the gantry frame is connected to a lower beam via a drive assembly.

Two closing magnets are fixedly connected to the left side of the inner wall of the top of the upper beam, and two opening magnets are fixedly connected to the right side of the inner wall of the top of the upper beam. Limiting wheel assemblies are fixedly connected to the inner walls of both the front and rear ends of the gantry frame. A fixed seat is fixedly connected to the left side of the inner wall of the bottom end of the gantry frame, and a support wheel is fixedly connected to the top of the fixed seat. Limiting components are provided on the inner wall of the gateposts.
[0007] Furthermore, the drive assembly includes a drive motor fixedly connected to the right side of the inner wall at the bottom end of the gantry frame, a rotating shaft fixedly connected to the drive end of the drive motor, and a drive wheel fixedly connected to the outer wall of the rotating shaft.
[0008] Furthermore, the outer wall of the drive wheel is disposed on the inner wall of the lower beam, and the drive wheel is used to drive the lower beam to move.
[0009] Furthermore, a partition is provided between each two adjacent connecting rods, and a reinforcing rod is fixedly connected to both the front and rear ends of each connecting rod.
[0010] Furthermore, the outer wall of the support wheel is set on the inner wall of the lower beam, a rear support wheel is set on the right side of the bottom end of the lower beam, a tail diagonal tie rod is fixedly connected to the right side of the top end of the lower beam, and the other end of the tail diagonal tie rod is fixedly connected to the right end of the upper beam.
[0011] Furthermore, a limit sensor is provided on the inner wall of the top of the gantry frame, and the inner end of the upper limit wheel set is provided on the outer wall of the upper beam, while the inner end of the lower limit wheel set is provided on the outer wall of the lower beam.
[0012] Furthermore, the limiting component includes a limiting seat fixedly connected to the inner wall at both ends of the door column. Each limiting seat is provided with an inward-facing guide wheel assembly, and the right ends of the two guide wheel assemblies are respectively fixedly connected to the left ends of the upper beam and the lower beam.
[0013] This utility model has the following beneficial effects:
[0014] During the movement of the lower beam, the support wheels always adhere to the upper and lower sides of the inner wall of the lower beam, limiting the vertical direction of the lower beam and supporting it in conjunction with the rear support wheels to prevent the suspended gate from becoming unstable due to its own weight. At the same time, the limiting wheel group will also limit the horizontal direction of the suspended gate to prevent it from shaking due to strong winds and being unable to enter the gate pillar.

Detailed Implementation
[0021] 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.
[0022] Reference Figure 1-4 An embodiment of this utility model is provided: an intelligent sensing energy-saving suspended door, including a gantry frame 1 and a door post 9. The bottom end of the gantry frame 1 is connected to a lower beam 10 through a drive assembly. The drive assembly includes a drive motor 15 fixedly connected to the right side of the inner wall of the bottom end of the gantry frame 1. The drive end of the drive motor 15 is fixedly connected to a rotating shaft 16. The outer wall of the rotating shaft 16 is fixedly connected to a drive wheel 17. The outer wall of the drive wheel 17 is set on the inner wall of the lower beam 10. The drive wheel 17 is used to drive the lower beam 10 to move. Multiple connecting rods 6 are fixedly connected to the top end of the lower beam 10. A partition 5 is provided between two adjacent connecting rods 6. Reinforcing rods 7 are fixedly connected to both the front and rear ends of the connecting rods 6. An upper beam 4 is fixedly connected to the top end of the connecting rods 6. Two closing magnets 8 are fixedly connected to the left side of the inner wall of the top end of the upper beam 4. Two opening magnets 3 are fixedly connected to the right side of the inner wall of the top end of the upper beam 4.
[0023] Specifically, in actual use, the drive motor 15 drives the rotating shaft 16 to rotate, causing the drive wheel 17 to rotate, which controls the movement of the lower beam 10. During the movement of the lower beam 10, the upper beam 4 will also move. The limit sensor 2 detects the opening magnet 3 and closing magnet 8 on the upper beam 4. When the limit sensor 2 detects the left opening magnet 3, it means that the left end of the upper beam 4 is about to enter the door post 9. At this time, the limit sensor 2 sends an electrical signal to control the drive motor 15 to slow down. When the limit sensor 2 detects the right opening magnet 3... When the upper beam 4 is fully inserted into the doorpost 9, the drive motor 15 can be controlled to stop and complete the closing. Similarly, when the limit sensor 2 detects the right closing magnet 8, it means that the door is about to open to its maximum range. When the left closing magnet 8 is detected, the drive motor 15 will be controlled to stop and complete the opening. The upper beam 4 and the lower beam 10 are connected by a connecting rod 6. The two adjacent connecting rods 6 are reinforced by a partition 5 and a reinforcing rod 7, which improves the stability of the suspended door and allows wind to pass through normally, thus enhancing its wind resistance.
[0024] Limit wheel sets 20 are fixedly connected to the inner walls of both the front and rear ends of the gantry frame 1. Limit sensor 2 is installed on the inner wall of the top end of the gantry frame 1. The inner end of the upper limit wheel set 20 is installed on the outer wall of the upper beam 4, and the inner end of the lower limit wheel set 20 is installed on the outer wall of the lower beam 10. A fixed seat 13 is fixedly connected to the left side of the inner wall of the bottom end of the gantry frame 1. A support wheel 14 is fixedly connected to the top of the fixed seat 13. The outer wall of the support wheel 14 is installed on the inner wall of the lower beam 10. A rear support wheel 12 is installed on the right side of the bottom end of the lower beam 10. A tail diagonal tie rod 11 is fixedly connected to the right side of the top end of the lower beam 10. The other end of the tail diagonal tie rod 11 is fixedly connected to the right end of the upper beam 4. A limit component is installed on the inner wall of the gate post 9. The limit component includes a limit seat 18 fixedly connected to the inner walls of both the front and rear ends of the gate post 9. An inlet wheel set 19 is installed on the inner end of each limit seat 18. The right ends of the two inlet wheel sets 19 are fixedly connected to the left ends of the upper beam 4 and the lower beam 10, respectively.
[0025] Specifically, during the movement of the lower beam 10, the support wheels 14 are always attached to the upper and lower sides of the inner wall of the lower beam 10, limiting the vertical direction of the lower beam 10, and supporting it in conjunction with the rear support wheels 12 to prevent the suspended gate from becoming unstable due to its own weight. At the same time, the limiting wheel group 20 also limits the horizontal direction of the suspended gate to prevent it from shaking due to strong winds and being unable to enter the gatepost 9. The guide wheel group 19 installed on the left end of the upper beam 4 and the lower beam 10 can guide the suspended gate, so that it can be limited by the limiting seat 18 after entering the gatepost 9, further improving the stability of the suspended gate during daily use, preventing it from shaking due to wind and hitting the inside of the gatepost 9 and causing damage, and extending the service life of the device.
[0026] Working Principle: In actual use, the drive motor 15 drives the rotating shaft 16 to rotate, causing the drive wheel 17 to rotate, which controls the movement of the lower beam 10. During the movement of the lower beam 10, the upper beam 4 will also move. The limit sensor 2 detects the opening magnet 3 and closing magnet 8 on the upper beam 4. When the limit sensor 2 detects the left opening magnet 3, it means that the left end of the upper beam 4 is about to enter the door pillar 9. At this time, the limit sensor 2 sends an electrical signal to control the drive motor 15 to slow down. When the limit sensor 2 detects the right opening magnet 3, it means that the left end of the upper beam 4 has completely entered the door pillar 9. At this time, the drive motor 15 can be controlled to stop and complete the closing. Similarly, when the limit sensor 2 detects the right closing magnet 8, it means that the door is about to open to its maximum. When the left-side closing magnet 8 is detected, the drive motor 15 will be controlled to stop and complete the opening. During the movement of the lower beam 10, the internal support wheel 14 will limit the vertical direction of the lower beam 10 to prevent the suspended door from becoming unstable due to its own weight. The rear support wheel 12 on the left side of the bottom of the lower beam 10 provides support and further improves the stability of the lower beam 10 during movement. The limiting wheel set 20 installed inside the gantry frame 1 can limit the horizontal direction of the upper beam 4 and the lower beam 10 during the movement of the suspended door to prevent the suspended door from shaking and being unable to enter the door head column 9 when strong winds blow. After the suspended door is closed, the limiting seat 18 inside the door head column 9 will also work with the guide wheel set 19 to limit the upper beam 4 and the lower beam 10 to ensure the stability of the suspended door.
[0027] 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.
