Description
Technical field
This utility model relates to elevator technology field, specifically a kind of crosshead sheave device.
Background technology
The car of elevator moves up and down, and mainly drives car to realize by moving up and down of hawser, wherein needs
The top of elevator is configured with car wheel assembly.
At present, when counterweight system is arranged on the both sides on sedan-chair top, its crosshead sheave typically has single crosshead sheave and double car roof wheels two
Plant arrangement, wherein, when using the arrangement of single crosshead sheave, owing to being limited by traction cornerite, may be only available for
The elevator that car width is less；And the arrangement of double car roof wheels, then there is no the restriction of car width, use the most widely
In various types of elevators.
Double car roof wheels arrangement of the prior art, it is directly rigidly connected in the upper master on sedan-chair top by crosshead sheave axle
Beam, or utilize rubber bodies to carry out primary damping simply, be so easily generated in running process of elevator elevator shake and
Noise, and elevator is when being turned to halted state by kinestate, the inertia of car can produce significantly vibrations, owing to not subtracting
Shake measure, or damping effect is poor, makes passenger produce sense of discomfort when taking elevator, and the speed that elevator runs is the highest, this
Uncomfortable vibrations are the most obvious, and these all have impact on the comfort of elevator, also directly affects quality and the city of elevator
?.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of stress and more equalizes, the crosshead sheave that structure is more stable
Device.
In order to solve above-mentioned technical problem, this utility model takes techniques below scheme:
A kind of crosshead sheave device, including top wheel carrier, clamping plate and the crosshead sheave assembly being located in clamping plate, clamping plate and top wheel carrier peace
Load connects, and is provided with connection main shaft in the wheel carrier of top, and this connection main shaft downwardly extends, and described connection main shaft lower end is set with locking screw
Mother, connects and is provided with clamp and lower clamp on main shaft, this is provided with between clamp and lower clamp main spring and two auxiliary springs,
Main spring is sleeved on connection main shaft and this main spring upper end rest against clamp, lower end rest against lower clamp, two auxiliary springs
It is separately positioned on main spring both sides, and the upper end of these two auxiliary springs rest against clamp, lower end rest against lower clamp.
The line footpath of described main spring is more than the line footpath of auxiliary spring.
Described main spring and auxiliary spring are torsion spring.
The auxiliary spring of said two is symmetricly set on the both sides of main spring.
Described connection main shaft is provided with shock-reducing rubber with the link position of top wheel carrier.
Locked by bolt between described top wheel carrier and clamping plate.
Described connection main shaft lower end is provided with split pin.
This utility model by arranging the different main spring in line footpath and two auxiliary springs, make top wheel carrier stress more balance and
Concentrate, it is ensured that integrally-built stability.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model cross-sectional view.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, the utility model will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, this utility model discloses a kind of crosshead sheave device, including pushing up wheel carrier 9, clamping plate 10 and being located at folder
Crosshead sheave assembly 11 in plate 10, clamping plate 10 are installed with top wheel carrier 9 and are connected, are provided with connection main shaft 1, this connection master in the wheel carrier 9 of top
Axle 1 downwardly extends, and described connection main shaft 1 lower end is set with locking nut 6, connects and is provided with clamp 2 and lower clamp on main shaft 1
4, this is provided with between clamp 2 and lower clamp 4 main spring 5 and two auxiliary springs 3, main spring 5 is sleeved on connection main shaft 1 and should
Main spring upper end rest against clamp, lower end rest against lower clamp, and two auxiliary springs 3 are separately positioned on main spring 5 both sides, and
The upper end of these two auxiliary springs rest against clamp, lower end rest against lower clamp.The line footpath of main spring is more than the line footpath of auxiliary spring.
Main spring and auxiliary spring are torsion spring.Main spring is more than auxiliary spring, and main spring is as main stress load, and two auxiliary springs are as auxiliary
Help stress load.Two auxiliary springs are symmetricly set on the both sides of main spring.
It is provided with shock-reducing rubber 8 additionally, connect main shaft 1 with the link position pushing up wheel carrier 9, reduces vibration.Top wheel carrier 9 and clamping plate 10
Between locked by bolt, bolt is locked with corresponding nut, the grade of this bolt is not less than 8.8 grades.Connect main shaft
Lower end is provided with split pin.
Main spring is as Main Load point, and its line footpath is bigger, it is possible to make crosshead sheave device more balance.Two auxiliary springs
Line footpath is less relative to main spring, crosshead sheave device stress can be made more to concentrate as auxiliary loads.Thus utilize one big two
It is more reliable and more stable that little spring structure makes to put forward overall structure.
It should be noted that the above is not the restriction to technical solutions of the utility model, without departing from this practicality
On the premise of novel creation design, any obvious replacement is all within protection domain of the present utility model.
