Abstract
The invention relates to an elevator crosshead sheave device which comprises diversion sheaves, a sheave cover, a damping device and an upper beam. The diversion sheaves are installed at two ends of the sheave cover, the sheave cover is connected with the upper beam through the damping device, the damping device is installed at two ends of the upper beam, and the center line of the sheave cover and the center line of an elevator guide rail coincide. The elevator crosshead sheave device is characterized in that the car unbalance loading can be reduced, so that an elevator can be more stable in operation. In addition, due to the fact that the damping device is arranged, vibration generated during elevator operation is effectively reduced, and elevator comfort sensation is improved.
Description
Technical field
The present invention relates to elevators field, particularly a kind of elevator car top wheel device.
Background technology
In existing elevator technology, lift car is that crosshead sheave axle directly passes through anchor ear, be connected directly between the upper beam of car rigidly, owing to lacking glissando, when lift car transfers stopping to from motion, because the inertia of car produces larger vibrations, and easily can produce shake and noise in running process of elevator, reduce the comfort of passenger.
Summary of the invention
In order to solve the deficiencies in the prior art, the object of this invention is to provide a kind of can be elevator smooth running and provide the elevator car top wheel device of elevator comfort more.
To achieve these goals, a kind of elevator car top wheel device provided by the invention, comprise diversion sheave, rope sheave cover, shock absorption device and upper beam, described diversion sheave is arranged on the two ends of described rope sheave cover, described rope sheave cover is connected with described upper beam by described shock absorption device, described shock absorption device is arranged on the two ends of described upper beam, and the line of centers of described rope sheave cover overlaps with cage guide line of centers.
Advantageously, described diversion sheave line of centers overlaps with cage guide line of centers.
Preferably, described rope sheave cover is connected with described upper beam by spring.
Preferably, described rope sheave cover is connected with described upper beam by rubber.
A kind of elevator car top wheel device provided by the invention, can reduce cabin uneven loading, more steady when elevator is run, and in addition, owing to being provided with shock absorption device, efficiently reducing the vibrations produced when elevator runs, improves the comfort of elevator.
Accompanying drawing explanation
Fig. 1 is the structural representation of the preferred embodiment of the present invention;
Fig. 2 is preferred embodiment of the present invention scheme of installation.
Wherein,
1, diversion sheave; 2, rope sheave cover; 3, shock absorption device; 4, upper beam.
Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of elevator car top wheel device provided by the invention, comprise diversion sheave 1, rope sheave cover 2, shock absorption device 3 and upper beam 4, described diversion sheave 1 is arranged on the two ends of described rope sheave cover 2, described rope sheave cover 2 is connected with described upper beam 4 by described shock absorption device 3, described shock absorption device 3 is arranged on the two ends of described upper beam 4, and the line of centers of described rope sheave cover 2 overlaps with cage guide line of centers, is arranged on front and back upper beam that two pieces is told 4 after rotating.Preferably, described diversion sheave 1 line of centers overlaps with cage guide line of centers, thus reduces cabin uneven loading, more steady when elevator runs, and the mode that more traditional center connects is stressed at two ends when elevator runs, and there will not be stressed bending phenomenon.
Preferably, shown shock absorption device 3 can make spring, also can select rubber, thus efficiently reduces the vibrations produced when elevator runs, and improves the comfort of elevator.
The invention has the advantages that, can cabin uneven loading be reduced, more steady when elevator is run, in addition, owing to being provided with shock absorption device, efficiently reducing the vibrations produced when elevator runs, improve the comfort of elevator.
More than describe preferred specific embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design concept according to the present invention can make many modifications and variations without the need to creative work.Therefore; all technical personnels in the art according to design concept of the present invention on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should within the scope of the present invention and/or by the determined protection domain of claims.
