AI Technical Summary
Existing industrial doors cannot sense foreign objects across the entire range during their up and down movement, and lack anti-pinch functions, resulting in an inability to effectively protect people or objects.
Using wireless light barriers and micro switches in conjunction with a transmission mechanism, the movement of door and window components drives the wireless light barriers to sense objects or people, and transmits signals to the servo motor to pause the movement of the door. Combined with counterweights and guide plates, full-range sensing and anti-pinch functions are achieved.
The wireless grating realizes full-range sensing during the movement of doors and windows, effectively preventing objects or people from being clamped, improving safety and simplifying structural design.

[0002] Industrial doors are commonly used facilities in enterprises. They are suitable for large warehouses, logistics industries, medicine, food, factories and mining enterprises and other industries that have relatively high requirements for opening speed, insulation, sound insulation, sealing, wind resistance, etc., especially in places with large door openings and inconvenient to install ground doors, which can provide convenient and quick opening.
[0003] At present, there are still some problems in the use of industrial doors in factories or warehouses. That is, the industrial doors in the existing technology install gratings or other sensor heads at the upper or lower end of the door to sense foreign objects at the upper or lower end. If foreign objects need to be sensed throughout the entire up and down process of the door, a long grating needs to be installed in the side groove of the door to cover the entire range for full-range sensing. This structure is too complicated as a whole and only simply moves up and down without an anti-pinch function. Therefore, it cannot provide protection for people or objects moving back and forth. For this reason, we have proposed an anti-pinch industrial door to solve the above problems. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0023] The utility model provides a technical solution: Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, in this embodiment, an anti-pinch industrial door includes a door head cover 1, a door post 2 is fixedly provided at the bottom of the door head cover 1, a door window part 3 is provided on one side of the door post 2, a bottom beam 4 is provided on the door window part 3, both ends of the bottom beam 4 are inserted into the interior of the door post 2, an inner strip 5 is fixedly provided on the outside of the bottom beam 4, an outer strip 6 is fixedly installed on the outside of the inner strip 5, a convex strip 7 is fixedly installed on the outside of the outer strip 6, a bracket plate 8 is abutted on the outside of the outer strip 6, a wireless grating 9 is fixedly provided on the bracket plate 8, and the wireless grating 9 is located on one side of the bottom beam 4. There is a micro switch 10, and a guide plate 11 is fixedly installed on the bracket plate 8. The guide plate 11 is inserted into the inside of the limit rod 12, and the limit rod 12 is fixedly set on the inner wall of the door column 2. A transmission mechanism for rolling up the door and window parts 3 is provided in the door head cover 1. When the door and window parts 3 are started to roll up by the transmission mechanism, the bottom beam 4 drives the inner strip plate 5 and the outer strip plate 6 to move, that is, the inner strip plate 5 and the outer strip plate 6 can be on the outside of the bracket plate 8 for sliding. As the bottom beam 4 continues to rise, the convex strip plate 7 can press against the switch on the micro switch 10, thereby being able to control the wireless The grating 9 is opened. When the door and window parts 3 are lowered, when the wireless grating 9 senses an object or a person, it can send a signal to the servo motor 23 on the transmission mechanism to suspend work, thereby effectively avoiding pressing the object or the person. The idea of this structure is to let the wireless grating 9 move with the door and window parts 3, so that the entire range of sensing can be achieved. A counterweight 13 is fixedly installed on the outside of the bracket plate 8. The counterweight 13 is located on one side of the wireless grating 9 and below the limit rod 12. By providing the counterweight 13, the bracket plate 8 can be forced to fall downward by gravity. The outer side of the inner strip plate 5 is in contact with the bracket plate 8, and the inner strip plate 5 and the outer strip plate 6 can slide on the outer side of the bracket plate 8. The convex strip plate 7 is located directly below the micro switch 10, so that when the bottom beam 4 moves upward, the inner strip plate 5 and the outer strip plate 6 can slide on the outer side of the bracket plate 8, and can subsequently drive the bracket plate 8 to be pulled upward. The guide plate 11 can slide on the outer side of the limit rod 12, and a square body is extended to the outer side of the limit rod 12, which can guide the bracket plate 8 moving up and down, so that the bracket plate 8 can move smoothly in the door post 2.
[0024] like Figure 2 and Figure 5As shown, the door and window component 3 includes a wind-resistant strip 14, a slide groove 15 is provided on the wind-resistant strip 14, a slider 16 is inserted in the slide groove 15, a door curtain 17 is fixedly provided on the slider 16, and the door curtain 17 is fixedly connected to the bottom beam 4. The wind-resistant strip 14 is arranged in an arc shape. By providing the door and window component 3, the slider 16 and the door curtain 17 are fixedly connected, so that personnel can quickly insert the slider 16 into the slide groove 15, so as to replace the door curtain 17 that is damaged after long-term use. A square groove is provided on the door curtain 17, and a window 18 is fixedly provided in the square groove. Through the window 18, personnel can observe the situation on the opposite side.
[0025] like Figure 6 As shown, the transmission mechanism includes a winding shaft 19, which is rotatably connected to the inside of the door head cover 1, and a rotating shaft 20 is fixedly installed on the outside of the winding shaft 19, and a large conical tooth 21 is fixedly installed on the outside of the rotating shaft 20, and the outside of the large conical tooth 21 is meshed with a small conical tooth 22, and the bottom end of the small conical tooth 22 is fixedly connected to the end of the rotating shaft of the servo motor 23, and the servo motor 23 is fixedly arranged in the inside of the motor cover 24, and the motor cover 24 is fixedly installed on the outside of the door head cover 1. By providing this structure, as the servo motor 23 drives the small conical tooth 22 to rotate, the small conical tooth 22 and the large conical tooth 21 engage and rotate, so that the winding shaft 19 can be rotated in the door head cover 1, thereby rolling up and lowering the door and window parts 3.
[0026] The utility model provides an anti-pinch industrial door, the specific working principle of which is as follows:
[0027] When the device is in use, as the servo motor 23 drives the small conical teeth 22 to rotate, the small conical teeth 22 and the large conical teeth 21 engage and rotate, so that the reel 19 can be rotated in the door head cover 1, so that the door curtain 17 can be rolled up on the outside of the reel 19. During this period, the door curtain 17 can pull the bottom beam 4 to move upward, so that the inner strip plate 5 and the outer strip plate 6 can slide on the outside of the bracket plate 8. As the bottom beam 4 continues to rise, the convex strip plate 7 can press against the switch on the micro switch 10, thereby turning on the bracket plate 8. A wireless light barrier 9 is provided for opening work. When the door and window parts 3 are lowered, when the wireless light barrier 9 senses an object or a person, it can send a signal to the servo motor 23 on the transmission mechanism to suspend work, thereby effectively avoiding pressing the object or the person. When the object or the person walks out of the range, the servo motor 23 continues to work, so that the door curtain 17 is closed. In this article, the wireless light barrier 9, the micro switch 10 and the servo motor 23 are electrically connected, and their structure and principle are relatively mature in the existing technology, so they are not elaborated in detail here.
