Abstract
The utility model relates to the technical field of elevators, and discloses a novel elevator landing door device which comprises an upper base plate component and a landing door hanging plate component, and the landing door hanging plate component is connected to a guide rail of the upper base plate component in a hanging mode. A bar-shaped groove extends from the lower edge of the guide rail and limits a hanging plate pressing wheel component in the up-down direction and the front-back direction, and the hanging plate pressing wheel component is located in the bar-shaped groove and can move in a reciprocating mode in the left-right direction of the bar-shaped groove. The novel elevator landing door device solves the technical problem that an existing landing door device is poor in using safety, when the novel elevator landing door device is actually applied to an overall elevator landing door system, a landing door which is mounted through the hanging plate pressing wheel component and the upper base plate component can move left and right freely in a reciprocating mode, even if the landing door is forcedly pushed by external force, the landing door can only slightly shake back and forth, and the novel elevator landing door device accords with all indexes about elevator landing door device safety requirements in the GB7588 elevator manufacturing and mounting safety specification.
Description
Technical field
The utility model relates to the novel elevator layer door gear in a kind of elevator technology field.
Background technology
Elevator landing door comprises upper sill frame assembly, layer door hanging plate assembly, weight steel rope assembly and closing appliance, and layer door hanging plate assembly is suspended on the guide rail of upper sill frame assembly by door change gear, and can move along guide rail.
As shown in Figure 1; upper sill frame assembly 1 in existing elevator landing door; its guide rail 2 parts are positioned at the waist of upper sill frame assembly 1 integral body; this guide rail 2 parts belows conventionally have an extension 7 in order to layer door hanging plate assembly 3 on link plate pinch roller assembly 4 coordinate, to avoid layer door hanging plate assembly 3 guide rail 2 parts from upper sill frame assembly 1 under the effect of external force to come off.But due to above-mentioned layer door hanging plate assembly 3 with upper sill frame assembly 1 does not carry out any cross spacing between the two or be unidirectional cross spacing, therefore after layer door installed with layer door hanging plate assembly 3, when external force is thrusted layer door, layer door there will be the situation of rocking back and forth, still there is the risk coming off in the layer door in the excessive said structure of horizontal thrust even, affects the usage safety performance of whole elevator landing door.
Summary of the invention
The purpose of this utility model is to provide a kind of working stability and safe novel elevator layer door gear in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the novel elevator layer door gear that the present invention is designed, comprise upper sill frame assembly and be articulated in the layer door hanging plate assembly on the guide rail of upper sill frame assembly, the lower edge of this guide rail is also extended with one can be to carrying out spacing bar-shaped trough on the above-below direction of link plate pinch roller assembly and fore-and-aft direction, link plate pinch roller assembly is positioned at this bar-shaped trough, and can move reciprocatingly on the left and right directions of bar-shaped trough.
Under there is under external force situation that layer door hanging plate assembly up lifted in elevator door, in order to guarantee that the layer door hanging plate assembly in the utility model still can normally move on upper sill frame assembly, the groove sidewall of described bar-shaped trough upper end is interior low outer high skewed, in described link plate pinch roller assembly, the outer ring of pinch roller is similarly dip plane, and matches with direction of tilt and the degree of dip of above-mentioned groove sidewall.
The novel elevator layer door gear that the utility model obtains, can be to carrying out spacing bar-shaped trough on the above-below direction of link plate pinch roller assembly and fore-and-aft direction along being also extended with one under the guide rail of upper sill frame assembly in its structure, link plate pinch roller assembly is positioned at this bar-shaped trough, and can move reciprocatingly on the left and right directions of bar-shaped trough.Therefore the elevator landing door of said structure is in whole elevator landing door system during actual use, the layer door of installing by link plate pinch roller assembly and upper sill frame assembly can not only be made left and right reciprocating action freely, even if there be thrust layer door of external force, layer door also only there will be the slight situation of rocking back and forth, meets GB7588 < < elevator and manufactures and the indices of installing in safety standard > > about elevator landing door safety requirements.
Accompanying drawing explanation
Fig. 1 is the side schematic view of existing elevator landing door;
Fig. 2 is the structural representation that the utility model provides novel elevator layer door gear;
Fig. 3 is the schematic cross-section at D-D place in Fig. 2.
In figure: upper sill frame assembly 1, guide rail 2, lower to 2-1, layer door hanging plate assembly 3, link plate pinch roller assembly 4, closing appliance 5, weight steel rope assembly 6, extension 7, door change gear 8, the capable groove 9 of bar, groove sidewall 9-1, pinch roller 10, outer ring 10-1.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
Embodiment:
As shown in Figures 2 and 3, the novel elevator layer door gear that the present embodiment provides, comprise upper sill frame assembly 1, by door change gear 8, be articulated in a pair of layer door hanging plate assembly 3 on the guide rail 2 of upper sill frame assembly 1, for realizing this to the closing appliance 5 of layer door hanging plate assembly 3 interlockings and driving this weight steel rope assembly 6 to layer door hanging plate assembly 3 closures, on described layer door hanging plate assembly 3, link plate pinch roller assembly 4 has also been installed, this guide rail 2 lower is also extended with one along 2-1 can be to carrying out spacing bar-shaped trough 9 on the above-below direction of above-mentioned link plate pinch roller assembly 4 and fore-and-aft direction, link plate pinch roller assembly 4 is positioned at this bar-shaped trough 9, and can move reciprocatingly on the left and right directions of bar-shaped trough 9, the groove sidewall 9-1 of described bar-shaped trough 9 upper ends is interior low outer high skewed, in described link plate pinch roller assembly 4, the outer ring 10-1 of pinch roller 10 is similarly dip plane, and match with direction of tilt and the degree of dip of above-mentioned groove sidewall 9-1.
