Abstract
The utility model discloses a landing door device of an elevator, which is used for controlling a landing door for passing in and out each landing of the elevator. The landing door device of the elevator comprises an upper sill assembly, a door strap, a door hanging wheel and a locking device, wherein the upper sill assembly is provided with a guide rail, and the locking device is used for controlling to open or close the landing door. The door hanging wheel is installed on the door strap, and the door strap is fixed on the guide rail through the door hanging wheel and can slide along the guide rail. The guide rail is rectangular, or the upper and the lower end surfaces of the guide rail are cambered. The door hanging wheel is in line contact with the guide rail. Compared with the prior art, the landing door device of the elevator adopts the rectangular guide rail or the guide rail with the cambered upper and the lower end surfaces, and the door hanging wheel is in line contact with the guide rail. Compared with the point contact of the prior art, the contact is more reliable, the running of the door hanging wheel on the guide rail is more stable, and the safe performance is increased. The guide rail adopts a hollow rectangular tube or a circular tube, so that the cost of materials is saved under the premise that the strength is ensured, meanwhile the hollow structure can also absorb the shock and noises generated by the door strap moving on the guide rail, and the noise pollution is reduced.
Description
Technical field
The utility model relates to the elevator technology field, especially relates 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, and door strap is suspended on the guide rail of bank assembly through the door change gear, and can prolong guide rail and move; Existing guide rail upper surface and lower surface be shaped as arc, and the door change gear be shaped as " V " font, so contacting to point of door change gear and guide rail contacts; During operation; Fiduciary level is not high, with the time point contact, has increased the wearing and tearing of stress point place guide rail and door change gear; Make the lost of life of guide rail and door change gear parts, increased the cost of safeguarding and change.
Summary of the invention
The utility model technical matters to be solved 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 utility model 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 utility model adopts following technical scheme: a kind of elevator door device comprises 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 utility model, the described guide rail of the utility model is a rectangle, and this rectangle is a hollow structure.
Compared with prior art, the utlity model has following advantage:
1, the utility model guide rail 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 to the elevator door device of the utility model, and a door change gear contact with guide rail line, with the some exposure phase ratio of prior art, 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 the structural representation of the utility model.
Fig. 2 is the lateral plan of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model 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, a 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 along guide rail 2, guide rail 2 and last 1 detachable connection of bank are formed with certain air gap between guide rail 2 and last bank 1; This gap can solve through the mode that spacer is set between guide rail and last bank, and the number of spacer can be 2,3 even more according to stressed situation setting.
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, therefore with the external surface shape of guide rail 2; 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.
