Abstract
The utility model discloses a traction machine with two traction sheaves. The two traction sheaves are arranged on a main shaft of the traction machine in a spaced and splining mode. The traction machine is provided with the two traction sheaves; when used, the traction machine is installed in an elevator system, and the two traction sheaves are distributed on the front side and the rear side of main guide rails respectively, so that spatial interference between the two traction sheaves and the main guide rails is avoided. Meanwhile, as the two traction sheaves are located on the plane perpendicular to the plane where the two main guide rails are located, space of a hoistway in the direction of the two main guide rails will not be enlarged. In addition, because the traction sheaves are not located on the plane where the two main guide rails are located, the traction machine can be very close to the main guide rails, the space of the hoistway is saved mainly, and the two traction sheaves can operate more stably.
Description
Technical field
The utility model relates to a kind of towing machine, relates in particular to the towing machine of a kind of pair of traction sheave.
Background technology
The role that elevator performer in modern architecture is important, especially, in villa, all villas are all equipped with elevator substantially.Elevator is arranged in hoistway, carry out motion guide by main guide rail and secondary guide rail, and realize up-and-down movement by towing machine traction, in the prior art, main guide rail has two main guide rails, be arranged on respectively the left and right sides of hoistway, and have respectively a secondary guide rail in the both sides, front and back of a main guide rail, secondary guide rail is also fixedly mounted in hoistway.Car guiding is arranged on main guide rail, the motion guide that main guide rail is car.Towing machine of the prior art as depicted in figs. 1 and 2, include support 1, in support, rotational support is provided with main shaft 2, main shaft 2 is driven by the motor 3 of fixed installation support one end, be equipped with a traction sheave 4 in the middle part of main shaft 2 spline, motor 3 rotates and just can drive traction sheave 4 to rotate by main shaft 2, is arranged with the steel rope that drives car on traction sheave 4.In installing in order to prevent the interference of traction sheave and main guide rail, towing machine must be contained in the outside of two main guide rails, and traction sheave is not interfered with main guide rail, like this, on the left and right directions of hoistway, just must reserve the installing space of towing machine, meanwhile, for towing machine is keeped in repair, also must in hoistway, stay the service clearance of enough towing machines, this just causes the shared space of hoistway to strengthen.Because the traction sheave of common villa ladder towing machine is mounted in the center on main shaft, whole elevator arrangement well rear traction sheave longitudinal plane of symmetry just overlaps with the longitudinal plane of symmetry of main guide rail, use common towing machine just to require to install the machine room space of this towing machine required enough, namely hoistway must be enough large, so that traction sheave and main guide rail do not interfere.This will be unfavorable for improving the degree of utilization of villa elevator hoistway space, is also unfavorable for reducing the cost of traction system.
Utility model content
The purpose of this utility model is to provide the towing machine of a kind of pair of traction sheave, because the machine room space that traditional traction sheave is mounted in the towing machine causing the center on main shaft is required enough large, be unfavorable for the problem of the degree of utilization that improves villa elevator hoistway space with solution.
In order to realize above object, the utility model adopts following technical scheme:
A towing machine for pair traction sheave, on the support of this towing machine, rotational support is provided with main shaft, and on the main shaft of described traction sheave, interval spline is provided with two traction sheaves, and two traction sheaves are in the main shaft section being between two strong points of support.
Towing machine of the present utility model has two traction sheaves, in use, towing machine is arranged in elevator device, and make two traction sheaves be distributed in the both sides, front and back of main guide rail, spatially can not interfere with main guide rail, simultaneously, because two traction sheaves are in the plane vertical with two main guide rail place planes, can not increase the hoistway space in two main guide rail directions, effectively raise the degree of utilization of hoistway, moreover, traction sheave is not in the plane at main guide rail place, towing machine just can from main guide rail very close to, towing machine is fixed on corresponding main guide rail by the top of link span, mainly can save hoistway space like this, can also make two traction sheave operations more steady, the center of gravity of car also can be all the time at the zone line of two traction sheaves, cage operation is stable, shake less.

Detailed description of the invention
An embodiment for the towing machine of pair traction sheave, in Fig. 5 and Fig. 6, in conjunction with Fig. 3 and Fig. 4, on the support 14 of this towing machine, rotational support is provided with main shaft 15, is provided with motor 12 in one end of support 14, and the motor 12 is here permagnetic synchronous motor.Motor 12 is in transmission connection with main shaft 15, can drive main shaft rotating shaft, and on main shaft 15, interval spline is provided with two traction sheaves, the first traction sheave 13 and the second traction sheave 16, and other structures of this towing machine are the same with towing machine of the prior art.
In the time that the towing machine in the present embodiment is applied in elevator device, the first guide rail 5 of elevator device and the second guide rail 6 are separately fixed at the left and right sides of the hoistway that is contained in elevator, establish respectively the first secondary guide rail 7 and the second secondary guide rail 8 in the both sides, front and back of the first guide rail 5, two secondary guide rails are also fixed in hoistway, the car guiding of elevator is arranged on main guide rail, mounting means is the same with mounting means of the prior art, be fixedly installed base 11 in the upper end of two secondary guide rails, on base 11, fixedly mount also towing machine 9, this towing machine 9 is fixed on base by support 14, on the support 14 of towing machine 9, rotational support is provided with main shaft 15, be provided with motor 12 in one end of support 14, the motor 12 is here permagnetic synchronous motor.Motor 12 is in transmission connection with main shaft 15, can drive main shaft rotating shaft, and on main shaft 15, interval spline is provided with two traction sheaves, the first traction sheave 13 and the second traction sheave 16, and other structures of this towing machine are the same with towing machine of the prior art.The both sides, front and back that are distributed in the first guide rail 5 of the first traction sheave 13 and the second traction sheave 16, like this, towing machine 9 can be close to the first guide rail 5 and arrange, be provided with link span 10 in the middle part of towing machine, link span 10 is for to bend by a plate angle steel shape structure forming, the part plate body of link span 10 corner one sides is close to towing machine and is fixed with towing machine, and the part plate body of the other side of link span 10 corners is close to the first guide rail 5 fixing with the first guide rail 5.
