Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and particularly to an arrangement method of a junction box in a traction machine. Background Art

[0002] In recent years, the demand for machine-room-less elevators has been increasing day by day. In the prior art, the designs for machine-room and machine-room-less traction machines often adopt different solutions, resulting in the non-universalization of the traction machine structure. Among them, in machine-room-less elevators, the wrap angle of the traction steel wire rope is mostly 180°. For the convenience of maintenance in the machine room, the junction box is often arranged at the end face position. However, in machine-room elevators, based on the requirements of civil engineering layout, the wrap angle of the steel wire rope is often set to be less than 180°. If the arrangement method of the junction box of the machine-room-less traction machine is adopted, the steel wire rope will interfere with the junction box, thus making it impossible to unify the specifications of machine-room and machine-room-less traction machines, and increasing the production manufacturing and maintenance costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an arrangement method of a junction box of a traction machine that can achieve the unified arrangement of the structures of machine-room and machine-room-less traction machines and can meet the maintenance requirements of the traction machine.

[0004] To solve the above technical problem, the present invention provides a traction machine, including a machine base, a motor junction box, a brake junction box, a brake assembly, and a traction wheel. Both sides of the machine base have a first mounting surface and a second mounting surface; the front of the machine base is perpendicular to the axis of the traction wheel; the motor junction box is installed on the first mounting surface of the machine base; the brake junction box is installed on the second mounting surface of the machine base; the brake assembly is installed on the machine base and is located above the center line of the machine base; the projections of the traction wheel on the motor junction box and the brake junction box do not overlap in all directions.

[0005] Preferably, the projections of the motor junction box and the brake junction box in the vertical direction completely fall within the projection of the machine base in the vertical direction.

[0006] Preferably, the first mounting surface and the second mounting surface on the machine base are located below the brake assembly.

[0007] Preferably, the first mounting surface and the second mounting surface intersect with the horizontal plane where the center line of the machine base is located.

[0008] Preferably, the first mounting surface and the second mounting surface are perpendicular to the rotation plane of the traction wheel.

[0009] Compared with the prior art, in the present invention, the installation position of the junction box is arranged staggeredly with the position of the traction sheave, and the projections of the junction box and the traction sheave in all directions do not coincide. The installation surface is located near the center line position of the machine base, and the installation surface is perpendicular to the rotation plane of the traction sheave. Under various wire rope wrap angles, the wire rope and the traction sheave will not interfere with each other, and the junction box does not affect the external dimensions of the traction machine after installation. While facilitating installation and maintenance, the unified structural layout of the traction machines with machine rooms and without machine rooms is realized. BRIEF DESCRIPTION OF THE DRAWINGS
