Description

Technical Field

[0001] The utility model relates to the technical field of elevator doors, in particular to a fast repair and anti-pinch device for elevator doors. Background Art

[0002] As an important means of transportation in modern buildings, the safety and convenience of elevators are crucial to people's daily lives. However, elevator doors are often damaged during use due to various reasons, such as collisions, wear, etc., which affects the overall appearance and safety of the elevator. When repairing elevator doors, the current conventional operating methods are manual maintenance or use of corresponding auxiliary tools for maintenance.

[0003] In addition, due to the structure and installation method of the elevator door itself, a component that drives the elevator door to move is set on the top of the elevator door, and the component is generally installed in the elevator shaft, or directly installed in the wall on one side of the elevator shaft. The drive component cannot be directly installed on the side of the wall that is exposed to the outside. During maintenance operations, staff are required to enter the elevator shaft or the opening and closing parts of the elevator door, which affects the repair efficiency and is not conducive to rapid repair operations. At the same time, standing at the opening and closing parts of the door body is also prone to pinching, which brings inconvenience to maintenance personnel. In view of this, we proposed a rapid repair and anti-pinch device for elevator doors. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 The utility model provides a technical solution: a quick repair and anti-pinch device for elevator doors, comprising a door frame 1, an elevator door 11 arranged on the door frame 1, and a driving assembly 2 arranged on the top of the door frame 1, wherein the driving assembly 2 is used to drive the elevator door 11 to complete the opening and closing operation, and the driving assembly 2, the elevator door 11 and the door frame 1 are all existing conventional technologies, which will not be described in detail here;

[0027] Specifically, an outer protective frame 3 is provided on the outside of the driving component 2, and the driving component 2 is fixedly mounted on the bottom wall of the outer protective frame 3. A bottom sliding hole 30 is provided on the bottom wall of the outer protective frame 3, and the bottom sliding hole 30 is used for the driving member in the driving component 2 to slide. A top flaring sleeve 31 is fixedly installed on the top of the outer protective frame 3, and an inspection chamber 32 is provided in the outer protective frame 3 and the top flaring sleeve 31. The front end of the inspection chamber 32 is connected to the outside for inspection operation, so that when performing inspection operation, the staff can stand directly in front of the elevator door 11 without standing between the two elevator doors 11, and can directly perform inspection operation on the driving component 2 in the inspection chamber 32, which is convenient for quick inspection and anti-pinch protection.

[0028] In this embodiment, a storage groove 10 is provided in the door frame 1 , and the elevator door 11 is located in the storage groove 10 and is slidably connected to the storage groove 10 , so that the elevator door 11 can slide normally in the storage groove 10 .

[0029] Specifically, grooves 111 are provided on the sides of the two elevator doors 11 that are close to each other, and infrared sensors 112 are fixedly installed on the groove walls of the grooves 111. The infrared sensors 112 are used for human body sensing operations. The infrared sensor 112 is a device that can sense infrared rays. It uses the physical properties of infrared rays to perform measurements. In the elevator door sensing system, the infrared sensor 112 determines whether there is a person near the door by emitting infrared rays and detecting the signal reflected or passing through objects. If a person or object enters the sensing range, the infrared sensor 112 will receive a reflected or blocked signal, thereby triggering the corresponding action of the elevator door, such as keeping it open or reopening it. The infrared sensor 112 and the elevator door sensing system are existing conventional technologies and will not be described in detail here.

[0030] Furthermore, side fixing frames 33 are fixedly installed at both ends of the outer protection frame 3, and the side fixing frames 33 are fixed in the wall by a plurality of fastening bolts, so as to realize portable installation operation.

[0031] In addition, a shielding cover plate 35 is hinged on the front side of the bottom plate of the outer protection frame 3 through a hinge. The shielding cover plate 35 is used to shield the inspection chamber 32 to achieve a protective effect.

[0032] It is worth mentioning that two symmetrical hooks 34 are fixedly installed on the front side surface of the top plate body of the top expansion sleeve 31, and two symmetrical buckles 36 are fixedly installed on the front side surface of the shielding cover plate 35. The buckles 36 are snap-fitted with the hooks 34 to facilitate the fixing operation, and also make it easier to open the shielding cover plate 35, thereby achieving the effect of facilitating quick maintenance.

[0033] It is worth noting that a rubber ring 351 is provided on the surface of the shielding cover plate 35, and the rubber ring 351 is pressed against the front side of the outer protection frame 3 and the top expansion sleeve 31 for sealing operation, thereby achieving a better sealing protection effect and reducing the entry of dust.

[0034] In this embodiment, two ends of the outer protection frame 3 are connected to the outside for ventilation and heat dissipation.

[0035] When the elevator door quick repair and anti-pinch device of the present invention is in use, when a fault occurs in the elevator door 11, it proves that a fault occurs in the drive assembly 2. At this time, the buckle 36 is unfastened, the shielding cover plate 35 is opened, and the staff then stands in front of the elevator door 11 and uses the corresponding ladder to climb to the height of the drive assembly 2. After the shielding cover plate 35 is opened, the maintenance chamber 32 is directly exposed to the outside, and the staff can directly perform maintenance operations on the drive assembly 2 in the maintenance chamber 32 to achieve rapid maintenance. Moreover, the staff stands in front of the elevator door 11 and does not need to stand between the two elevator doors 11, so the anti-pinch protection operation can be achieved to the greatest extent.
