The elevator door protective device
The utility model relates to the elevator technology field, is specifically related to a kind of elevator door protective device.
In the elevator manufacturing, usually be collectively referred to as the elevator door protective device with elevator cage, toeguard and with the attaching parts that elevator cage and toeguard link together.Related request according to standard GB 7588-2003, elevator hoistways wall under each landing sill of elevator must have one and the direct coupled vertical surface of landing sill, this surface should be continuous, constitute by smooth and hard material, and when being subjected to being evenly distributed on the power of the 300N on 5 sq cm circles or the square-section perpendicular to any point on it, should not have permanent deformation, its elastic deformation is not more than 10mm.In addition, this hoistway arm is answered: the door eyebrow that 1) is connected to next door; Or 2) adopt hard smooth inclined-plane to extend downwards.Generally, the fixed form of toeguard links together by sill support channel and sill on the toeguard as shown in Figure 3, captives joint with two fixed support 3a on being fixedly connected on the elevator hoistways sidewall in the lower end of toeguard; In addition, as shown in Figure 4, be used for fixing sill about two sill support channel 1a, 1b complex structure, therefore above-mentioned elevator door protective device installation procedure complexity not only, the cost of installation height, and, because of adopting steel plate, makes toeguard, so the Heavy Weight of toeguard, the price height, thus increased productive costs.
The utility model content
The utility model is in order to solve the installation procedure complexity that exists in the elevator door protective device of the prior art and toeguard Heavy Weight, problem of ultra-high price, provide a kind of simple in structure, easy for installation, and the intensity height of toeguard, in light weight, elevator door protective device that price is low.
To achieve these goals, the utility model is by the following technical solutions: a kind of elevator door protective device, comprise the sill support channel that is fixedly connected on the elevator hoistways sidewall, the toeguard that is arranged on the sill on plane on the sill support channel and is located at the sill support channel side, described sill support channel one side is captiveed joint with the elevator hoistways sidewall, opposite side is captiveed joint with toeguard, and described toeguard is hanging shape away from an end of sill.The utility model is arranged by rational structure, simplified the mode that installs and fixes of toeguard, two fixed supports that are used for fixing the toeguard lower end in the existing elevator door protective device have been saved, only need during installation toeguard is connected on the sill support channel with bolt and get final product, thereby simplified erection procedure greatly.
As preferably, described sill support channel quantity is 3, and shape is together the crotch shape that is made of three right angle flangings, and in the equidistant arrangement of elevator hoistways sidewall horizontal.Because toeguard has saved two fixed supports when mounted and directly has been fixed on the sill support channel, therefore the contour structures with two sill support channels about original changes into and middle three the same straight flange crotch shapes of sill support channel, not only simplified the structure of sill support channel, make things convenient for the installation of toeguard and sill support channel simultaneously, reduced installation requirement; The equidistant arrangement of three sill support channels helps the stressed even of toeguard.
As preferably, described toeguard is shaped on an inclined-plane away from an end of sill, and the end on inclined-plane is hanging shape.Save fixed support, simplified the structure and the erection procedure of toeguard.
As preferably, the thickness of described toeguard is 2mm～4mm, when satisfying requirement of strength, alleviates its weight with cost-cutting as far as possible.
As preferably, the material of described toeguard is a glass-felt plastic.The mechanical strength of glass-felt plastic is 1.4 times of steel approximately, therefore, the toeguard that its intensity of toeguard that the employing glass-felt plastic is made and rigidity are higher than steel significantly, the correlation technique that not only can satisfy fully in the national standard requires and regulation, but also two fixed supports that are used for fixing the toeguard downside in the existing elevator door protective device have been saved, only need during installation toeguard is fixedly connected on the sill support channel and get final product, thereby simplified erection procedure greatly.In addition, that glass-felt plastic has is in light weight, price is low, the advantage of withstanding corrosion and good insulating, and therefore, the toeguard made from glass-felt plastic has also obviously reduced the manufacturing and the cost of installation of whole elevator door protective device except having the favorable mechanical physical property.
In sum, the utlity model has following beneficial effect: (1) has saved the fixedly fixed support of toeguard, and the structure of two sill support channels has reduced manufacturing cost about having simplified, and has simplified erection procedure; (2) toeguard adopts glass-felt plastic to make, and has improved mechanical strength, has reduced manufacturing cost.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
At Fig. 1, among the embodiment shown in Figure 2, elevator door protective device of the present utility model comprises three crotch shape sill support channels 1 that are made of three right angle flangings, three sill support channels 1 are equidistant horizontally on the elevator hoistways sidewall, and the flanging of sill support channel 1 one sides is captiveed joint with the elevator hoistways sidewall with expansion bolt 5, flanging in the middle of the sill support channel 1 up, its upper side is captiveed joint with sill 2, on the flanging of sill support channel 1 opposite side, be provided with the toeguard made from glass-felt plastic 3, the inclined-plane 32 that toeguard 3 is extended by a upright plane 31 and upright plane 31 lower ends downward constitutes, its thickness is 2.2mm, captive joint with sill support channel 1 with bolt 4 in the top of toeguard 3, inclined-plane, its underpart 32 1 ends are unsettled.Because of the price of glass-felt plastic low, and has the mechanical strength height, in light weight, advantage such as withstanding corrosion and good insulating, therefore, the correlation technique that every mechanical and physical performance of the toeguard 3 that the employing glass-felt plastic is made can satisfy in the national standard fully requires and regulation, two fixed support 3a that are used for fixing toeguard 3 lower ends in the existing elevator door protective device have also been saved simultaneously, and three sill support channels 1 are all made the crotch shape that constitutes by three right angle flangings, only toeguard 3 usefulness bolts 4 need be fixedly connected on three sill support channels 1 during installation and get final product, thereby obviously reduced the manufacturing cost of whole elevator door protective device, simplified erection procedure greatly.
