Description

Door machine structure for full-circle passenger elevator

Technical Field

The utility model relates to an elevator door machine structure, in particular to a door machine structure for a full-circle passenger elevator.

Background

Compared with the conventional square passenger elevator, the full-circle elevator has unique visual aesthetic feeling and use environment, and is widely applied to villa elevators. The door machine structure of the traditional full-circle elevator drives the door plate to rotate to open and close by means of the cooperation of the motor and the gear rack, but the door machine structure is relatively complex, occupies large space and cannot meet the design requirements of manufacturers. To above-mentioned defect, present full circle elevator adopts swing arm structure to replace gear structure to drive the door plant, and this swing arm structure is as shown in patent 201710770736.0, through rotating the one end of swing arm and connecting at the car top, the door plant top is connected to the other end for the rotation of swing arm's around the axle can drive the door plant and make circumferential direction rotate and realize the function of opening and shutting. On the basis, the swing arms can be directly driven to rotate through the motor, and synchronous rotation of the swing arms at two sides can be realized through a chain transmission mechanism in the patent, so that mirror image opening and closing work of two door plates is realized.

When the structure is in actual use, because the weight of the door plate is large, if the door plate is supported only by the swing arm, a cantilever structure can be formed, namely the downward inclination of the swing arm at one end close to the door plate is easy to cause, and the rotation stability and the safety of the door plate are reduced. Under the above limitation, the current door machine system needs to adopt a rail to support and rotate the door plate to limit, namely, the upper end and the lower end of the door plate are connected onto the rails of the upper sill and the lower sill of the elevator through brackets in a sliding manner, and the end part of the swing arm is connected onto the top bracket. Under this state, the swing arm only provides the circumference drive function to the door plant, and the support of door plant and slip spacing then rely on both sides track to guarantee the stability of door plant height position and rotation position. However, the structure has the defect that the door plate is limited by three positions in the actual rotation process due to the installation mode, namely, the sliding limit of the upper sill rail, the sliding limit of the lower sill rail and the direct driving of the swing arm; the door plate of the full-circle elevator needs to rotate circumferentially, so that the rotation smoothness of the door plate is greatly related to the roundness and concentricity of the upper sill track and the lower sill track, and the driving route of the swing arm to the door plate is required to be ensured to be consistent with the sliding route of the tracks on the two sides; once the three parts have route deviation due to processing or installation errors, the problem of clamping stagnation and noise of the door plate can be caused, and the door plate can be bent and deformed when serious. But in the actual processing process, the upper ridge track and the lower ridge track are required to be bent into circular arc shapes by straight plates, so that the roundness and concentricity of the two tracks after bending are difficult to be completely consistent, and the perfect circular arc shapes are difficult to be formed by bending, namely, the circular arc shapes are different from the driving route of the swing arm. Under the limitation of the factors, the processing and installation difficulty of the existing full-circle elevator door machine structure is extremely high, and the smoothness of the door plate during rotation cannot be guaranteed.

Therefore, the door machine structure of the existing full-circle elevator has the problems of difficult processing and installation and poor rotation stability of the door plate.
