Description

Elevator door anti-falling device

Technical Field

The utility model relates to the technical field of elevators, in particular to an elevator door anti-falling device.

Background

The elevator is an indispensable important component in modern buildings, and is convenient and quick to become the best choice for people to walk in the buildings. However, in the face of the increasingly large number of elevators, the safety of the elevators is more and more emphasized by people, and especially, the elevator door is separated from the door leaf due to the impact of abnormal external force, so that the elevator falling accident is most concerned.

Among the current lift-cabin door guide structure, the door slider is generally from last down the disect insertion sill guide way in, when the door receives unusual external force impact in the in-service use process, the door leaf can take place to warp, makes the door slider drop from the guide way easily, has the potential safety hazard or the loss of property that the personnel fell.

In order to avoid the emergence of above-mentioned falling ladder accident, many industry producers set up the boss through setting up on the sill guide way, set up the metal on the door slider and hinder the piece, and the boss clearance on the guide way is less than the metal and hinders piece size, and when the door received unusual external force and assaulted, the door slider was followed to the ascending in-process in the guide way, and the metal hinders the piece and is met the boss on the sill guide way and be blocked to reach the mesh that prevents that the door slider from droing from the guide way.

Because the boss clearance on the sill guide way is less, is difficult for clearing up below the boss, and door slider and sill are easily by the foreign matter winding, lead to the card between door slider and sill to die.

Detailed Description

For a further understanding of the present invention, reference is made to the following detailed description taken in conjunction with the accompanying drawings 1-3.

With reference to fig. 1-3, the elevator door anti-drop device of the present embodiment includes a sill 1 having a sill guide groove 1 a; the door sliding block 2 is fixedly connected with a hoistway door above the door sliding block 2, the bottom of the door sliding block is provided with a flexible sliding block 3 capable of sliding in the sill guide groove 1a, and the flexible sliding block 3 can slide along the length direction of the sill guide groove 1a and can also slide up and down along the height direction of the sill guide groove 1a, so that the door sliding block 2 can be vertically arranged and can be conveniently installed; a plurality of damping grooves 1b are distributed on the side wall of the sill guide groove 1a along the height direction, a damping boss 4 arranged towards the damping groove 1b is fixedly connected to the bottom of the door slider 2, the damping boss 4 can be arranged upwards or downwards or horizontally, the damping boss 4 is covered in the flexible slider 3, when the door slider is not impacted, the damping boss 4 slides in the sill guide groove 1a and cannot enter the damping groove 1b, when the hall door is impacted by abnormal external force and the hall door deforms little, the damping boss 4 on the door slider 2 contacts with the side wall of the sill guide groove 1a, the door slider 2 bears a large horizontal force in the sill guide groove 1a and moves upwards, at the moment, the horizontal force can press the damping boss 4 of the door slider 2 into the damping groove 1b on the guide groove 1a (the damping boss 4 extrudes the flexible slider 3 on the corresponding side), after continuously passing through the plurality of damping grooves 1b, energy of abnormal external force impact is absorbed, thereby preventing the door slider 2 from falling off from the sill guide groove 1 a.

This lift-cabin door anticreep device can effectively be anticreep, improves the security when anticreep device uses, simple to operate simultaneously, and the door slider 2 is straight up-down installs in sill guide way 1a, and is convenient for clear up the foul in sill guide way 1 a.

As an alternative of the present invention, a plurality of damping grooves 1b are uniformly distributed on the side walls of both sides of the sill guide groove 1a, and at this time, the damping bosses 4 are respectively arranged on both sides of the bottom of the door slider 2, so that a good anti-falling function can be realized regardless of the inside and outside impact force applied to the hall door.

As an alternative scheme of the utility model, the door slider 2 and the damping boss 4 are integrally formed, the door slider 2 and the damping boss 4 are both made of metal materials, and the integrally formed door slider 2 and the damping boss 4 have high strength, so that when the hall doors are impacted, the door slider 2 can effectively drive the damping boss 4 to enter the damping groove 1b to achieve the purpose of preventing falling.

As an alternative of the present invention, the damping boss 4 is disposed downward, so that when the hall door is hit, the damping boss 4 located downward can enter the damping groove 1b more quickly for the purpose of coming off, and the damping boss 4 disposed upward or horizontally can also serve the purpose of coming off, but the damping boss 4 disposed downward does not come off quickly when it comes into effect.

As an alternative of the present invention, the door slider 2 is a straight-plate type, the top of the door slider is provided with a door plate connecting structure, and the door plate connecting structure may be a bent structure, that is, the door slider 2 is a vertical plate structure, and when the hall door is impacted, the straight-plate type door slider 2 can more rapidly transmit a horizontal impact force to the damping boss 4, so that the damping boss 4 can more rapidly enter the damping groove 1b to achieve the purpose of preventing falling.

As an alternative of the present invention, the flexible sliding block 3 is made of a flexible wear-resistant material, such as a polyurethane elastomer or natural rubber, so as to effectively improve the wear-resistant performance of the flexible sliding block 3 when sliding in the sill guide groove 1a, and simultaneously ensure that the damping boss 4 can press the flexible sliding block 3 into the damping groove 1b when being impacted.

As an alternative of the present invention, in order to facilitate cleaning of the damping groove 1b and avoid dead cleaning corners, the groove depth of the damping groove 1b is 0.5-3mm, the groove width of the damping groove 1b is 0.5-3mm, for example, the groove depth and the groove width are both 1mm, or the groove depth and the groove width are both 0.5mm and 3mm, or the groove depth and the groove width are both 3mm and 0.5mm, etc.

The present invention and its embodiments have been described above schematically, without limitation, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching, without departing from the spirit of the utility model, the person skilled in the art shall not inventively design the similar structural modes and embodiments to the technical solution, but shall fall within the scope of the utility model.
