Description

Technical Field

[0001] This invention relates to the field of elevator door technology, and more specifically, to a high-security elevator door. Background Technology

[0002] Elevator doors are a crucial component of elevators. There are two types of doors: the one visible from the outside, fixed to each floor, is called the hall door; the one visible from the inside, fixed to the car and moving with it, is called the car door. In the prior art, patent document CN209081222U discloses a novel elevator door, comprising an elevator door body and guide rails. The elevator door body consists of two door panels. Rollers are fixed between the bottom sides of the door panels and the guide rails. The door panels extend into the guide rails, and rollers and supports are fixed to the bottom of the extended portion. Brushes are installed at the bottom of the supports. A linkage rod is installed inside the extended portion of the door panels. The device uses a shovel to clean stubborn dust in the groove and uses a dust collection box to collect the dust, making dust disposal convenient. However, existing elevator hall doors mostly use a double-track fixed structure, meaning the stress points of the hall door are mainly concentrated on the upper and lower tracks, while the middle of the hall door lacks a corresponding stress-bearing support structure. This makes the elevator hall door susceptible to deformation under external forces, thus reducing the safety of the hall door. At the same time, existing elevator hall doors lack a necessary electrical detection mechanism. Based on this, the present invention provides a high-safety elevator door to solve the technical problems mentioned in the background art. Summary of the Invention

[0031] Please see Figure 1-9 The present invention is a high-safety elevator door, the technical solution of which includes a door frame 1, a transmission module and an electrical control module respectively installed on the upper part of the door frame 1, and an annular drive belt 2 connected to the peripheral side of the transmission module.

[0032] The transmission module includes a transmission motor 7 fixed to the top surface of the gantry 1 and two symmetrically arranged and rotatably connected wheel axles 8 inside the gantry 1.

The circumferential side of both pulleys is connected to the annular drive belt 2. The pulleys are "I" shaped wheels.

[0033] The electrical control module includes an electrical control box 9 fixed to the surface of the gantry 1. The electrical control box 9 has a built-in microcontroller and a remote central control module. The end face of the electrical control box 9 is equipped with a central control panel and an audible and visual alarm. The ports of the battery, the central control panel and the audible and visual alarm are all electrically connected to the microcontroller. The data port of the remote central control module transmits data bidirectionally with the microcontroller.

[0034] Two transmission frames 3 are mounted on the surface of the annular drive belt 2. The surfaces of the two transmission frames 3 are slidably connected to the gantry 1. The two transmission frames 3 are synchronously linked in opposite directions through the annular drive belt 2. A gantry 4 is mounted on the bottom surface of the two transmission frames 3.

[0035] The upper part of the gantry 1 has two symmetrically arranged guide wheel grooves a. The surface of the transmission frame 3 is equipped with two sets of symmetrically arranged upper guide wheels. The peripheral sides of the two sets of upper guide wheels are slidably connected to the two guide wheel grooves a respectively. The lower part of the gantry 1 is fixedly provided with a guide wheel groove b.

[0047] The scissor telescopic assembly includes a set of "X"-shaped connecting frames 14 arranged in a linear array and hinged in pairs. Fixed hinge seats 15 are fixedly installed on the surfaces of both the fixed frame 10 and the movable frame 11. Movable hinge seats 16 are slidably connected inside both the fixed frame 10 and the movable frame 11. The inner walls of both the movable hinge seats 16 and the fixed hinge seats 15 are hinged to the "X"-shaped connecting frames 14 at adjacent positions.

[0048] The linkage components include a driven gear 17 fixed to the top of the roller 12 and a transmission worm gear 18 rotatably connected to the top of the fixed frame 10. A differential shaft 19 is rotatably connected to the inner wall of the gantry 1. A differential bevel gear is fixedly installed at the tail end of the differential shaft 19. An active bevel gear that meshes with the differential bevel gear is fixedly installed at the end of the wheel axle 8. The peripheral side of the differential shaft 19 is connected to the transmission worm gear 18 via a belt. The axes of the transmission worm gear 18 and the differential shaft 19 are both perpendicular to the axis of the wheel axle 8.

[0049] The vertical protection mechanism includes a horizontally arranged air cylinder 20 fixed to the surface of the gantry 1 and a vertically arranged piston cylinder 21 fixed to the surface of the gantry 1. An air-blowing piston 22 is slidably connected to the inner wall of the air cylinder 20. An air guide pipe 23 is fixedly installed at the axial position of the end face of the air-blowing piston 22 and slidably connected to the air cylinder 20. The surface of the air guide pipe 23 is fixedly connected to the transmission frame 3 at an adjacent position. A pressure relief chamber 24 is fixedly arranged between the tail face of the air-blowing piston 22 and the opposite surface of the air cylinder 20. A pressure relief port communicating with the pressure relief chamber 24 is fixedly opened at the tail end of the air cylinder 20. A pneumatic cavity is fixedly arranged between the end face of the air cylinder 20 and the opposite surface of the air cylinder 20. An air guide channel 25 is fixedly opened at the axial position of the air guide pipe 23. The tail end of the air guide channel 25 is connected to the pneumatic cavity.

The ports of the pressure probe 28 and the electromagnetic valve 29 are both electrically connected to a single-chip microcomputer.

[0051] The working principle of this invention is as follows: This elevator door is an elevator hall door. When the elevator door is working, the two doorposts 4 are driven by the ring drive belt 2 and move in opposite directions at the same speed. When the two doorposts 4 move, the roller 12 moves synchronously, thereby realizing the synchronous winding and unwinding of the inner metal mesh 13. When the doorposts 4 move, the scissor telescopic component extends and retracts automatically, thereby effectively improving the anti-collision strength of the doorposts 4 and the door panel 5. When working, when the two doorposts 4 are fully closed or when the vibration sensor 32 generates abnormal vibration feedback, the locking rod 27 penetrates into the locking groove 6, thereby locking the position of the two doorposts 4 and improving the anti-collision and anti-deformation strength of the doorposts 4. When the elevator door is powered off, the battery provides backup power for the elevator door. External maintenance personnel can control the doorposts 4 to open in the absence of external power by rotating the electric opening button 33 with a special tool.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
