Problems solved by technology
The driving device is arranged in the space between the hoistway wall of the elevator hoistway and the elevator car, so the space must have sufficient size to install the driving device, and an extremely flat driving device must be designed to reduce the space of the hoistway, otherwise the driving device The local space occupied will lead to the increase and waste of the space of the whole lifting channel
However, as the load of the elevator increases, the thickness of the driving device is almost unavoidable
At the same time, because the driving pulley of the driving device is parallel to the side of the car, there is a blind spot for the repair and maintenance of the driving device, that is, the side of the driving device close to the hoistway wall of the lifting passage cannot be repaired and maintained, such as the inspection of the encoder, etc.

Embodiment Construction
[0015] see figure 1 As shown, the machine-room-less elevator device of the present invention comprises a hoisting passage 1, a car 4 ascending and descending in the hoisting passage 1, a counterweight 7 or a rope tensioning device, a driving pulley 3 and a drive for lifting the car 4. device 2.
[0016] A kind of preferred embodiment is to adopt elongated driving device, and the axial dimension of driving device 2 is larger than the diameter of driving pulley 3, and driving pulley 3 is substantially perpendicular to the edge of adjacent car 4, and driving pulley 3 is perpendicular to the edge of car 4. The projections of the car 4 in the lifting direction do not overlap. The braking device 16 of the drive device 2 can be arranged in the opposite direction to the drive pulley 3 . The rope 13 of elevator device can adopt the rope that diameter is not more than 8mm, if driving pulley 3 diameters and rope 13 diameter ratios are less than or equal to 40, then the width of driving...

The invention discloses an elevator apparatus without a machine room, including an elevator car elevating in an elevating passage, a counterweight or rope tensioning device, a drive device having a drive pulley and elevating the elevator car, a rope rolling and hanging between the drive pulley, the elevator car and the counterweight or rope tensioning device, and an elevator car portal crane device. The drive device is arranged on an upper space of the top of the elevating passage. The projection portions of the drive device and the elevator car portal crane device in an elevating direction overlap, and the projection portions of the drive device and the elevator car top in the elevating direction do not overlap. At the same time the projection portion of the drive device in the elevating direction is in a shadow area a, and the shadow area a partially comprises the projection of a layer-door device in the elevating direction. The elevator apparatus without the machine room of the invention has simple structure and easy installation, convenient repair and maintenance of the drive device, small top height and pit of the elevator and small hoistway area occupied by the elevator.
Description
technical field [0001] The invention relates to a machine room-less elevator device. Background technique [0002] In traditional elevators driven by traction sheaves, the mechanical room of the driving device and control equipment often occupies the top space of the building required by the elevator, and the layout of the mechanical room has many restrictions. This influences the utilization and the attractive in appearance of the space of building on the one hand, increases the expense of building on the other hand. With the advent of machine room-less elevator technology, the problems of traditional traction sheave-driven elevators have been solved. [0003] Chinese invention patent specification CN1130303C (announcement date: December 10, 2003) discloses a machine room-less elevator. The elevator device does not have a machine room. projection overlap. According to the overlapping relationship between the driving device, the car roof pulley connected to the driving de...
