The landing door collision-prevention device is 1.5 meters long and in large area contact with the landing doors, and when the landing doors are under external impact, the collision-prevention device can uniformly bear stress, can prevent effectively the landing doors from falling off under force impact, is simple in structure and convenient to assemble.
Description
Technical field
The present invention relates to the elevator field, especially a kind of elevator door anticollision device.
Background technology
Layer door is mounted in the elevator door of each floor position, and its Main Function arranges in order to prevent personnel from falling elevator hoistways, can only be when lift car be positioned at dock floor when normal the use, and the layer Men Caihui of this dock floor opens.
At present personnel fall elevator hoistways and the injures and deaths event that causes has the overwhelming majority all because layer door problem causes.Wherein mainly contain following reason: the one, the passenger, due to drunk or the other reasons shock layer door of exerting oneself, makes the distortion of layer door or damages; The 2nd, due to product quality problem, make layer door below door slide block come off, while causing someone to rely on layer door, layer door starts in hoistway.
Common layer door fixed form as shown in Figure 1 in the market: layer door upper end is connected with fixing layer door gear on the wall by bolt, the door slide block is installed by bolt in lower end, in the insert layer gate sill of door slide block below, layer door lower end is stuck in the landing sill sliding tray and is fixed.Landing door structure is as shown in Figure 2: layer door generally consists of layer door board, layer door upper plug head, layer door lower end cap, reinforced rib, a door slide block, layer door upper plug head, lower end cap and reinforced rib all are connected with layer door board by Type of Welding, the upper plug head perforate is for the articulamentum door gear, and the lower end cap perforate is for the connection door slide block.
By above structure, can find out, the welding of a layer lower end cap, a slide block are fixed with layer door lower end cap, and the problems such as intensity of a slide block itself all likely cause the anchor fitting inefficacy of layer door below, initiation safety misadventure.
In the technical scheme of patent No. KP10-20070032278, the collision prevention function that discloses layer door is by the situation that a guide groove of traditional sill increases guide groove, in new guide groove, midway location is installed two permanent seats, in the door and window lower middle position, a L-type hook is set, the L-type hook is slided in newly-increased guide groove.In layer door locking position, the L-type hook on the door leaf of both sides is inserted respectively permanent seat, thereby realizes the collision prevention function of layer door.But this technology exists significantly not enough: at first, the guide groove that sill newly increases has strengthened the width of sill, and cost raises; Secondly, because the sill width increases, must make layer door occupy larger hoistway space, cause the cage side sill to increase with respect to the well enclosure gap.Therefore, when occurring that car layer door unscheduled call is opening the door beyond zone, and sentence while opening the door situation, in car, the passenger is easy to occur the terraced accident of pendant.In addition, according to the requirement of elevator industry standard, when the cage side sill is greater than 120mm with respect to the well enclosure gap, side needs to increase cage door locking apparatus on car door again, will further increase cost.
In the technical scheme that is KR10-20070049692 in the patent No., set forth and a kind ofly closed the inferior horn place of the door leaf of side near layer door, a special door slide block with latch hook structure is installed or is directly set up a latch hook, latch hook slides in guide groove, in guide groove, midway location arranges a lock, at layer door, during in locked position, latch hook inserts lock, thereby realizes a layer door anticreep.The disadvantage that this technical scheme exists is: the inferior horn place (door pocket position) that closes the door leaf of side away from layer door can not realize anticreep, door slide block hauling-out sill guide groove herein still likely occurs, is stuck in above sill the fault while causing layer door to open the door.
In the technical scheme that is KP10-20070052003 in the patent No., mention at the midway location in the lading door dill outside and set up a lock, on layer every fan, a latch hook is installed, at layer door during in locked position, latch hook inserts lock, thereby realizes layer door anti-drop function.There is above-mentioned shortcoming equally in this scheme, in the position that latch hook is not set, the problem of the de-groove of slide block easily occurs, and, along with the increase of door opening width, de-groove problem is more outstanding.
In existing scheme in sum, the collision prevention function of the elevator door proposed, being based on the preventing layer door comes off in the situation of the slideway on sill and to propose, the enforcement of such scheme will inevitably increase the weight of elevator door and increase corresponding actuating device, increase the cost of whole elevator, although such scheme is the preventing layer door sill slideway that comes off to a certain extent, but what because of anti-collision facility, all adopt is a contact, if, in the situation that the larger situation that so there will be layer door inwardly to open of appointing of external force, crashproof effect is undesirable.
Summary of the invention
The objective of the invention is to solve above-mentioned prior art problem, a kind of elevator door anticollision device is provided, the form of employing face contact arranges anticollision device on original layer of door, increase crashproof contact surface in the situation that do not change existing elevator structure, better solve the problem that current elevator door comes off, farthest guaranteed the safety of layer door, avoided the user to fall into because of carelessness well, ensure passenger's safety, improve the safety factor of elevator.
The technical solution used in the present invention is: a kind of elevator door anticollision device, and comprise sill and be arranged on the fan of two on sill layer door and landing door jamb, described layer door lower end is provided with a slide block, and the door slide block inserts in the sliding tray of sill; The upper end of described layer door is connected with fixing layer door gear on the wall, and this device comprises layer door anticollision device, and described anticollision device is fixedly installed on respectively the side of two fan layer door.
In technique scheme, described layer door anticollision device is the bending part with spill.
In technique scheme, one side of described bending part is connected with the side of layer door, and when layer door closed, concave portions tips upside down on the U-shaped mouth of door pocket.
In technique scheme, the side opening of described layer door is provided with tapped bore, and described bending part is connected with the side of layer door by bolt.
In technique scheme, described layer door anticollision device length is 1.5mm.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows: with traditional anticollision device, compare, traditional anticollision device is all increase slide block or increase corresponding anti-collision facility on the slide block side in sill slides, the anticollision device that all belongs to a contact, and the anticollision device that this programme adopts is to belong at whole installation anticollision device contacted fully of layer reveal face, to belong to the face contact, from the mechanics angle, consider, the stressed degree of uniformity of face contact is greater than a contact certainly, under same large external force collision, the contact of layer door bearing surface more can be driven power than the some contact certainly.Therefore under onesize External Force Acting the crashproof effect of this programme than traditional crashproof successful many, the probability of layer Men Tuoli sill slideway is also just known many, therefore this programme has more crashproof effect, secondly enforcement of the present invention does not need to change the structure of existing elevator, order is installed, particularly layer door anticollision device can adopt the sheet material of any material, does not need special material, with low cost.
