Embodiment 1

[0033] see figure 1As shown, in Embodiment 1 of the present invention, the machine room-less elevator device includes a hoistway 1, a car 4 ascending and descending in the hoistway 1, a car door machine device 11, a car frame 17, and a counterweight 7 . A driving device 2 that drives the pulley 3 and lifts the car 4 up and down. The bottom of car 4 is equipped with two car undercarriage wheels 5. A counterweight wheel 6 is installed on the top of the counterweight 7 .

[0034] Described driving device 2 adopts the driving device of elongated shape, 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 connected with the car. 4 The projections 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 the elevator device can ...

Embodiment 2

[0045] see image 3 , 4 As shown, the machine room-less elevator device is basically the same as the first embodiment. The difference is that the drive device 2 is connected to the support beam 18 . The support beams 18 are supported by the front and rear walls of the hoistway 1 . Two anti-vibration rubbers 19 are respectively installed at the bottom of the support beam 18 . Two anti-vibration rubbers 19 can improve the vibration situation of the whole elevator system. Since the projection of the support beam 18 and the maintenance plane (shaded area b) at the top of the elevator car 4 in the lifting direction does not overlap, it will not affect the maintenance plane at the top of the elevator car 4 . The counterweight side rope head can be installed on the support beam 18 .

[0046] Compared with Embodiment 1, the advantage is that the counterweight guide rail 8 does not bear the external load brought by the driving device 2, so the strength requirement of the counterwe...

Embodiment 3

[0048] see Figure 5 , 6 As shown, the difference from Embodiment 1 is that the projection part of the driving device 2 and the elevator car door machine device 11 in the lifting direction overlaps, and the counterweight 7 is located in front of the side of the car 4 .

[0049] The car door machine device 11 and landing door device 12 of the elevator generally occupy a part of the cross-sectional area of ​​the hoistway 1 , especially they occupy more space on both sides of the elevator car 4 . Such as Figure 6 As shown, the size it occupies is about 300mm. The shaded area a in the figure is the area they occupy. Therefore, the present invention makes full use of this area, and partially arranges the driving device 2 within the area of ​​this area. When the load capacity of the elevator increases, only the axial dimension of the driving device 2 needs to be increased. The increased size of the driving device 2 can be arranged in the shaded area a, so that the driving devi...

Abstract

The invention discloses an elevator device, including a lifting channel, a car which is lifted in the lifting channel, a balance weight and a drive device which is provided with a drive pulley and drives the car to lift, a rope coiled and hung between the drive pulley, the car and the balance weight, a car gate machine device and a car frame. The drive device is arranged on the top part of the lifting channel and the part of the drive device is higher than the top part of the lifting channel space needed by the car along the lifting direction; and the projections of the drive device and the car are not overlapped on the lifting direction. The drive device is arranged at the upper side of the balance weight and at least partial projections of the drive pulley and the balance weight are overlapped on the lifting direction. The drive pulley is basically vertical to the edge of a neighboring car. The projections of the drive pulley and the car are not overlapped on the lifting direction. The elevator device of the invention has simple structure and is easy to mount; the repair and maintenance of the drive device is convenient; the top layer height and a pit of the elevator are small; the well area occupied by the elevator is small.

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...
