Abstract
The utility model discloses a hoistway door toe guard and belongs to lift mechanical parts. The hoistway door toe guard comprises a guard board. A groove is formed in the guard board, and at least three connection rods which are arranged in parallel are connected to the interior of the groove. The groove is formed in the guard board, the connection rods are connected to the interior of the groove, and therefore a ladder is formed. Maintenance staff can conveniently go out of a lift car and reach a ladder stand of a well. The hoistway door toe guard is simple in structure, convenient to use, capable of effectively playing a role of protection and isolation and being used as the ladder, convenient for the maintenance staff to move towards the well from the interior of the lift car, and capable of improving safety.
Description
Technical field
The utility model and elevator machine parts are used in particular for the toeguard of car Room door.
Background technology
Landing apron is mounted in the bottom of car sill, generally all is that fixed type is installed.Toeguard act on lift car not corresponding with layer door position the time, between car ground and the layer ground spacing is arranged, prevent that the passenger from falling in the hoistway from spacing.
A variety of landing aprons are arranged in the market, be a kind of rotatable toe guard of elevator car of CN102701057A such as publication number, it discloses sheet under a kind of toeguard upper slice that is hinged and the toeguard, be provided with the lever mechanism that rotates with elevator operation downwards at toeguard upper slice, on toeguard upper slice, also be provided with the coaxial cam that links to each other with lever mechanism, be provided with the connecting rod mechanism that spurs sheet upset under the toeguard with the cam rotation at cam, so that toeguard carries out the certain angle rotation, reduced the pit depth demand, toeguard need not to collide pit ground, avoids damaging toeguard and personnel's unexpected injury.
The most condition of service of landing apron is in elevator reparing, and when the maintainer entered the hoistway maintenance from car, the Room that need to walk around unlatching just can get at the cat ladder of hoistway both sides behind the door, and was very inconvenient, and has potential safety hazard.
The utility model content
The purpose of this utility model is to solve the problems of the technologies described above, and provides a kind of simple in structure, is conducive to the landing apron that the maintainer out gets at cat ladder in the car.
Technical solution of the present utility model is: a kind of landing apron, comprise backplate, and offer groove on the described backplate, connect the pipe link that be arranged in parallel more than at least two in the groove.
By offering groove at backplate, many pipe links of captive joint in the groove, the maintainer can be in the car out,, directly just climbs down and enter in the hoistway as ladder by pipe link.Need not walk around Room door like this, the maintainer just can get at cat ladder.
As preferably, the recess edge connection reinforcement bar of described backplate.Because groove need to connect pipe link, and pipe link needs the weight that can bear at least an adult, and the thickness of general backplate or intensity also are not enough to the bearing force that provides enough, so add strap stiffener, are used for improving firm intensity.
As preferably, offer the strip shape through hole in the both sides of described groove.For some especially big elevators, because middle recess width just can not play the original protective effect of toeguard by actv. too greatly, thus also offer through hole in the groove both sides, when moving to cat ladder for the convenient for maintaining personnel, as an acting point.
As preferably, a side of described backplate connects ladder moving up and down.
As further preferred, described ladder is positioned at the one or both sides of groove.For some especially big elevators, hoistway space is very large, and the ladder except intermediate groove place pipe link forms also need to add in both sides acting point again.For more convenient maintainer's motion, connect again chair moving up and down.Ladder just can be accepted when not using like this, guarantees that the length of toeguard can not exceed the degree of depth of pit.
As further preferred, backplate connects ladder by coupling assembling; Described coupling assembling comprises two guiding mechanisms that are fixed on the backplate, two orienting lugs that ladder upper end captive joint and guiding mechanism are connected, captive joint hydraulic actuating cylinder on the ladder.
As further preferred, described guiding mechanism comprises two fixed blocks that are fixedly connected on the backplate, connects pilot bar between two fixed blocks; The orienting lug of described ladder is socketed on the pilot bar.
As preferably, anti-skidding projection is set on the described pipe link.
As preferably, captive joint fastener on the described backplate.Fastener is used for backplate more firmly is fixed on lift car.
The utility model beneficial effect is: by offering groove at backplate, connect pipe link in the groove, form like this a ladder, the convenient for maintaining personnel out, can get at the cat ladder of hoistway in the car.This landing apron is simple in structure, and is easy to use, both can play the protective separation effect by actv., can work as again ladder and use, and the convenient for maintaining personnel move to hoistway in car, improve safety.

The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
The radial width of some large-scale cars is very large, the maintainer by the pipe link in the middle of the backplate in the car out, but the cat ladder from the hoistway limit still has a segment distance, so as shown in Figure 2, backplate 1 connects the ladder 5 that can move up and down again in the side back to layer door, is used for convenient for maintaining personnel's transverse shifting.And ladder 5 can move up and down, and obsolete the time, can draw ladder 5 in, and ladder 5 and backplate are closed up, and in the time of can guaranteeing pit like this, the length of backplate 1 is less than the degree of depth of pit, and backplate 1 need not to collide pit ground.Go back one on the backplate 1 and connected fastener 7, backplate 1 is fixed by fastener 7 and car, strengthens the intensity of backplate 1.
As described in Figure 3, ladder 5 can be connected to groove 1 residing position.The maintainer can continue to move down like this.
