Abstract
The utility model relates to an elevator landing door device, it is including the door guide rail, the initiative door strap, passive door strap, the door change speed gear, go up the nip drum wheel, return rope sheave bearing member, linkage wire rope, the wire rope mount, pressing plates, linkage wire rope walks around the rope sheave that returns that returns among the rope sheave bearing member respectively and forms cyclic annular return circuit, the middle part is equipped with with the clamp plate of wire rope assorted flute profile fixedly with the hookup of initiative door strap through the surface below the linkage wire rope, wire rope's the higher authority is passed through the wire rope mount and is fixed with passive door strap hookup, the initiative door strap is connected on the door guide rail with passive door strap difference passing -through door change speed gear and last nip drum wheel, the slide rail AND gate change speed gear of door guide rail and the race of last nip drum wheel cooperate, the slide rail of door guide rail is the slide rail of two -sided U -shaped. The utility model discloses because the two sides is the slide rail of U -shaped about the slide rail of its guide rail to drop reduced safety accident when what layer door received that external force collides that the disjunction gate change speed gear is difficult for leading to layer door when ageing.
Description
Technical field
The utility model relates to elevator field, particularly relates to a kind of elevator door device.
Background technology
Elevator door device is arranged on elevator hoistways side, supports the use with the door opener in elevator car door system, it is achieved the opening and closing of elevator door, plays protection passenger and passes in and out the personnel safety of lift car and close the effect waiting ladder mouth.
Existing elevator door device mainly comprises upper sill frame, door guide rail, door strap assembly, returns rope wheel component, linkage wireline, door lock, and door strap assembly comprises the active door link plate and passive door link plate that are arranged in a guide rail, and door guide rail is fixedly connected with upper sill frame; Active door link plate and passive door link plate are equipped with fixation rack for steel wire rope respectively; Two door straps are connected with linkage wireline by fixation rack for steel wire rope respectively, linkage wireline is walked around the rope wheel component that returns being arranged on a guide rail two ends respectively and is formed loop, and the tie point of the tie point of active door link plate and linkage wireline and passive door link plate and linkage wireline is just reverse in the direction of motion of linkage wireline. When active door link plate is carried out switch door action by sedan-chair railway carriage or compartment door machine, passive door link plate is by the effect also synchro-switch of linkage wireline. Active door link plate and passive door link plate hang wheel by door respectively and upper pressing roller is connected on a guide rail, the slide rail of door guide rail is hung with door and taken turns the upper slide rail contacted is U shape, the glidepath contacted with upper pressing roller of door guide rail is plane, active door link plate and passive door link plate drive door to hang the slide rail taken turns along door guide rail and move, door hangs wheel and upper pressing roller clamping door guide rail, thus prevents active door link plate or the passive door link plate door strap when being subject to big impact from departing from door guide rail.
There is following problem in said structure, upper pressing roller is that plane cooperation contacts with the slide rail of door guide rail, easily causes coming off of layer door when layer door is hung take turns aging by external force collision or door, causes security incident. Fixation rack for steel wire rope and linkage wireline, for being rigidly connected, are inconvenient to adjust the tensioning power of linkage wireline, and can be produced bigger shake when being subject to resistance when running during installation. Link the position deviation door extension wheel of wireline and the central horizontal line of upper pressing roller in addition, and during operation, door hangs the pressure that wheel is subject to vertical direction, and between door guide rail, frictional force increases, and operation resistance strengthens.
Practical novel content
The purpose of this utility model be to provide a kind of structure simple, operate steadily, elevator door device convenient for installation and maintenance.
The technical solution of the utility model is: a kind of elevator door device, it comprises a guide rail, active door link plate, passive door link plate, door hangs wheel, upper pressing roller, return rope wheel component, linkage wireline, fixation rack for steel wire rope, pressing plate, linkage wireline is walked around the rope sheave that returns returning in rope wheel component respectively and is formed cyclic loop, the following middle part of linkage wireline is provided with the pressing plate of the flute profile mated mutually with wireline by surface and active door link plate is connected and fixed, the top of wireline is connected and fixed by fixation rack for steel wire rope and passive door link plate, active door link plate and passive door link plate hang wheel by door respectively and upper pressing roller is connected on a guide rail, the race that the slide rail of door guide rail hangs wheel and upper pressing roller with door matches, the slide rail of described door guide rail is the slide rail of two-sided U shape.
In order to convenient adjustment steel wire tensioning power, also comprising spring, described spring is arranged on the junction of wireline end and fixation rack for steel wire rope, adjusts the degree of tightness of wireline by tightening the nut of spring afterbody.
Coming off to prevent door-plate and the upper gap between pressing roller and door guide rail U shape slide rail of convenient adjustment, described upper pressing roller is eccentric wheel.
Compared with prior art, the beneficial effects of the utility model are: owing to the slide rail upper and lower surface of its guide rail is the slide rail of U shape, thus when layer door collide by external force or door hang wheel aging time not easily cause coming off of layer door, reduce security incident. Particularly, spring is set in the junction of wireline end and fixation rack for steel wire rope, thus installs or the convenient elasticity regulating linkage wireline during repair and maintenance at layer door, during operation also can shock absorbing better, reduce vibration. In addition, upper pressing roller is eccentric wheel, thus the upper gap between pressing roller and door guide rail U shape slide rail of convenient adjustment.
