Abstract
The utility model discloses a landing door device for an elevator, which is used for controlling a landing door through which people go in and go out of each landing of the elevator. The landing door device comprises an upper sill component provided with a guide rail, a door hanging plate, a door hanging gear and a locking device for controlling the opening or the closing of the landing door, wherein the door hanging gear is installed on the door hanging plate; the door hanging plate is fixed on the guide rail through the door hanging gear and can slide along the guide rail; the guide rail is rectangular or the upper end surface and the lower end surface of the guide rail are arc-shaped; and the door hanging gear is in line contact with the surface of the guide rail. Compared with the prior art, the landing door device for the elevator adopts the rectangular guide rail or the guide rail of which the upper end surface and lower end surface are arc-shaped, and the door hanging gear is in line contact with the guide rail; compared with the point contact in the prior art, the line contact is more reliable, and the door hanging gear is more stable to run on the guide rail, so that the safety performance is improved; as the guide rail adopts a hollow rectangular pipe or a circular pipe, on one hand, the material cost is saved on the premise of ensuring the strength; and meanwhile, with the adoption of a hollow structure, the vibration and the noise generated by the door hanging plate moving on the guide rail also can be absorbed, so that the noise pollution is reduced.
Description
Technical field
The present invention relates to the elevator technology field, especially relate to the elevator door device of the layer door of each stop of control turnover elevator.
Background technology
The elevator door device comprises bank assembly, door strap, door change gear and closing appliance; Door strap is suspended on the guide rail of bank assembly through the door change gear; And can prolong guide rail moves; Existing guide rail upper surface and lower surface be shaped as arc; And the door change gear be shaped as " V " font; So the door change gear is the some contact with contacting of guide rail; During operation; Fiduciary level is not high; Contact with time point; Increase the wearing and tearing of stress point place guide rail and door change gear, made the lost of life of guide rail and door change gear parts, increased the cost of safeguarding and change.
Summary of the invention
Technical matters to be solved by this invention is the deficiency to above-mentioned prior art, and provides a kind of operational reliability high elevator door device.
The further technical matters to be solved of the present invention provides a kind of elevator door device that reduces manufacturing cost and use cost and can effectively reduce noise.
For solving the problems of the technologies described above; The present invention adopts following technical scheme: a kind of elevator door device; Comprise the last bank assembly that is provided with guide rail; Door strap, door change gear and be used for the closing appliance that the key-course door opens or closes, described door change gear is installed on the door strap; Door strap is fixed on the guide rail through the door change gear; And can slide along guide rail, guide rail is connected with last bank is detachable, between described guide rail and last bank, is formed with certain air gap.
Described guide rail is that rectangle or guide rail upper and lower end face are arc, and described door change gear contacts with the guide rail surface line.
For solving the further technical matters to be solved of the present invention, described guide rail of the present invention is a rectangle, and this rectangle is a hollow structure.
Compared with prior art, the present invention has following advantage:
1, guide rail of the present invention is connected with last bank is detachable; Hollow structure has not only reduced material cost; This detachable designs simplification the technology of making; Simultaneously; Between guide rail and last bank, leave certain air gap; When the elevator door device moves, the vibration that air gap produces in the time of well absorbing the operation of elevator door device, thus reduced noise.
2, to adopt rectangle or upper and lower end face be the guide rail of arc for elevator door device of the present invention, and a door change gear contact with guide rail line, contacts with the point of prior art and compare, and contacts more reliably, and the operation of change gear on guide rail is more steady, the safety performance raising.
3, guide rail adopts hollow rectangular tube or pipe, on the one hand, under the prerequisite of proof strength, has saved material cost, and simultaneously, hollow structure also can absorb door strap and on guide rail, move vibrations and the noise that is produced, and has reduced noise pollution.
Figure of description
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the lateral plan of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing; The present invention is elaborated; With reference to figure 1 and Fig. 2; A kind of elevator door device; Comprise bank assembly 1; Door strap 3, door change gear 5 and be used for the closing appliance 4 that the key-course door opens or closes, last bank assembly 1 comprise with its on guide rail 2 through being threaded; Door change gear 5 is installed on the door strap 3; Door strap 3 is fixed on the guide rail 2 through door change gear 5, and can slide guide rail 2 and last 1 detachable connection of bank along guide rail 2; Between guide rail 2 and last bank 1, be formed with certain air gap; This gap can solve through the mode that spacer is set between guide rail and last bank, and the number of spacer can be 2 according to stressed situation setting; 3 even more.
The end face that is shaped as rectangle or contacts with the door change gear about it of guide rail 2 is an arc; The slot form of door change gear 5 is consistent with the shape of guide rail contact surface; Be plane or arcwall face; Just in time coincide with the external surface shape of guide rail 2; Therefore; When door change gear 5 moves on guide rail 2, just in time form line and contact with guide rail 2.
For the deadweight that reduces material cost and reduce the elevator door device, it is the hollow tubular of arc that guide rail 2 also can adopt upper and lower end faces such as hollow rectangle pipe, pipe, oval tube, and simultaneously, hollow structure also has the effect of good absorbing vibration and noise.
