Embodiment 1

[0021] See Figure 1 and image 3 , shows the structure of the present invention which is installed horizontally in the state of use. When the width of the hoistway is sufficient, it is installed horizontally in the hoistway, otherwise it is installed vertically in the hoistway or placed in the set machine room . The combination of the motor 1 and the reduction box 2 is the transmission connection, specifically through the brake drum 11 and the reduction box 2. The connection method belongs to the known technology, for example, you can refer to the text description of the publication number CN101020552A and the patent application figure 2 . The reduction box output shaft 21 is driven by the worm wheel 23, and one end of the reduction box output shaft 21 is supported on the second output shaft support 9b through the bearing 215. The casing is fixed; the other end of the reduction box output shaft 21 is supported on the first output shaft support 9a by inner and outer bearings...

Embodiment 2

[0026] please see figure 2 , provides the structure of the present invention which is shown as a vertical installation in the state of use, the first mounting base 4 plays the role of mounting and fixing, and the rest are the same as the description of the first embodiment.

Abstract

The invention relates to a passenger and goods elevator tractor suitable for frame-type machine-roomless installation, belonging to the technical field of lifting facilities. The tractor comprises a motor provided with a brake drum, a reduction gearbox which is linked with the motor in a transmission way and provided with a brake arm bracket, a traction sheave fixedly arranged at an output shaft of the reduction gearbox, a first mounting seat and a second mounting seat that are constructed on the reduction gearbox, and a power loss braking device comprising a brake arm and a power loss braker;wherein, the two ends of the output shaft of the reduction gearbox are propped against a first output shaft supporting seat and a second output shaft supporting seat which are fixed at the two sidesof the reduction gearbox and corresponding to each other; one end of the output shaft of the reduction gearbox extends out of the first output shaft supporting seat, and the traction sheave is fixed at the shaft end of the output shaft of the reduction gearbox extended out of the first output shaft supporting seat. The passenger and goods elevator tractor has the characteristic that the first andthe second output shaft supporting seats are of circular truncated cone shapes. And the passenger and goods elevator tractor has the advantages of simplifying the structure, being beneficial for processing, manufacturing and installing, in particular suitable for frame-type machine-roomless installation.

Description

technical field [0001] The invention belongs to the technical field of lifting facilities, and in particular relates to a traction machine for passenger and freight elevators suitable for frame-type machine room-less installation. Background technique [0002] As known in the industry, frame-mounted traction machines for passenger and freight elevators do not need to be equipped with a machine room, as long as the car and the guide rails in the hoistway form a sliding pair or a rolling pair. However, for traction machines of passenger and freight elevators installed without machine rooms, the structure is often required to be more concise. Of course, the prerequisite must be to ensure the safety and stability of operation. [0003] Chinese Utility Model Patent Authorization Announcement No. CN200974733Y discloses a traction machine for passenger and freight elevators (proposed by the applicant), the structure of which is shown in Figure 5, including a motor 1, a gear box 2 c...
