Compared with the prior art, the beneficial effects of the utility model are that:
this can promote hauler for elevator of wind spring elasticity, simple structure, simple to operate need not to heavily, need not the compensation chain, reduces hauler power, need not the elevator foundation ditch, low in cost, general user can both bear.
Drawings
FIG. 1 is a diagram: the utility model has a schematic structure;
FIG. 2 is a diagram of: the utility model discloses the driving sheave left side looks sideways at the schematic diagram.
In the figure: 1. a worm gear reducer; 2. a traction sheave; 3. a coil spring shaft; 4. braking in an embracing way; 5. a gearless tractor.
The drawings are for illustrative purposes only and are not to be construed as limiting the patent; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: the traction machine for the elevator comprises a traction sheave 2, a coil spring shaft 3 is arranged in an inner cavity of the traction sheave 2, a coil spring is wound outside the coil spring shaft 3, one end, far away from the coil spring shaft 3, of the coil spring is fixedly welded to the inner wall of the traction sheave 2, a worm and gear speed reducer 1 is connected to the right side of the traction sheave 2, a gearless traction machine 5 is installed on the left side of the traction sheave 2, and a brake 4 is installed between the gearless traction machine 5 and the traction sheave 2.
Wherein: a left transmission shaft of the worm gear speed reducer 1 penetrates through the right side of the traction wheel 2 and is arranged in an inner cavity of the traction wheel, and the left side of the transmission shaft is in transmission connection with the right side of the coil spring shaft 3;
the right side of the gearless traction machine 5 is arranged on the right side of the inner cavity of the traction sheave 2 in a penetrating and extending mode, and the right side of the gearless traction machine 5 is movably connected with the spring coiling shaft 3.
The working principle is as follows: the elevator car descends, the traction sheave 2 drives the coil spring to rotate, the coil spring shaft 3 is fixed, and the coil spring is wound more tightly to accumulate elastic force; when the lift car ascends, the traction machine 2 can slightly lift the lift car without large power under the action of the elastic force of the coil spring; when the elasticity is insufficient, the worm gear speed reducer 1 drives the coil spring shaft 3, so that the number of turns of the coil spring is increased, and the elasticity of the coil spring is increased.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "disposed," "connected," "fixed," "screwed" and the like are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate medium, and may be connected through the inside of two elements or in an interaction relationship between two elements, unless otherwise specifically defined, and the specific meaning of the above terms in the present invention will be understood by those skilled in the art according to specific situations.
The utility model discloses the standard part that uses all can purchase from the market, and dysmorphism piece all can be customized according to the description with the record of drawing of description, and the concrete connection mode of each part all adopts conventional means such as ripe bolt, rivet, welding among the prior art, and machinery, part and equipment all adopt prior art, and conventional model, including circuit connection adopts conventional connection mode among the prior art, does not detailed here again.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
