Abstract
The utility model provides a tensioning device of an elevator compensating rope. The tensioning device is characterized in that: the tensioning device comprises a guide rail and a crossbeam; the guiderail is vertically arranged on a well way bottom pit, the crossbeam is fixed on the side wall of the bottom pit, the upper end of the guide rail is fixed with the crossbeam, and a fixed seat which can move up and down along the guide rail is arranged on the guide rail; a rope wheel box, a counter poise and a damper are fixed on the fixed seat; the compensating rope is arranged in the rope wheel box, the two ends of the compensating rope are respectively connected with the bottom part of an elevator car and a frame of the counter poise, one end of the damper is fixed on the fixed seat, and theother end of the damper is fixed on the crossbeam. The beneficial effects of the tensioning device are as follows: under the function of the damper, the compensating rope of the rope wheel box is intensioning state at any time when the fixed seat moves up and down along the guide rail, which not only can exert good effect of shock absorption, but also can achieve the effects of lowering noise, improving comfort degree of taking an elevator, prolonging the service life of the elevator and ensuring safe running of the elevator; therefore, the tensioning device has promising market prospect.
Description
[technical field]
The utility model relates to manufacturing industry of the lift, relates to a kind of express elevator compensation rope tightening device in particular.
[background technology]
At present, existing express elevator system generally all includes car and counterweight, and they are suspended on the hoisting rope two ends that are arranged in elevator hoistways separately.Compensation rope one end be fixed on lift car below, the other end is captiveed joint with the bottom of counterweight, the compensation rope is walked around the rope sheave that is positioned at bottom the hoistway.When car and counterweight when alternatively up and down moves in hoistway, because the tension of compensation rope makes the vibration weakening of car in lifting process.
Yet the existing slack-free device of rope that will compensate mostly is spring structure, and spring often can play tension preferably in the car uphill process.But when car descended, it is relatively poor that the tension of spring just seems, the high vibration of car in the decline process can influence passenger's comfort.
Therefore, the utility model is further improved the compensating rope of elevator tightening device at above-mentioned deficiency.
[utility model content]
The purpose of this utility model provides a kind of good damping effect, and is simple in structure, improves the tightening device of the compensating rope of elevator of elevator comfort level.
For achieving the above object, the utility model by the following technical solutions:
A kind of tightening device of compensating rope of elevator is characterized in that including the guide rail that vertically is arranged on the well pit, is fixed on the crossbeam on the pit sidewall, and the upper end and the crossbeam of described guide rail fix; On guide rail, be provided with and be fixed with rope sheave case, counterweight and damper on the described permanent seat along the upper and lower mobile permanent seat of guide rail; Be provided with the compensation rope that two ends are connected with the counterweight framework respectively in the described rope sheave case bottom car; One end of described damper is fixed on the permanent seat, and the other end is fixed on the crossbeam.
The tightening device of aforesaid a kind of compensating rope of elevator is characterized in that described damper includes base, cylinder shell, cushion cylinder and piston sleeve; Described cylinder shell is arranged on the base; Described cushion cylinder is arranged in the cylinder shell, and and cylinder shell between have oil storage space, described cushion cylinder upper end is provided with the oilhole that communicates with oil storage space; Described piston sleeve one end inserts cushion cylinder inside, and is provided with orifice plug in the end, is provided with the cutoff port that communicates bottom cushion cylinder in the described orifice plug; Formed oily passage between the sidewall of described piston sleeve and the cushion cylinder, the sidewall of described piston sleeve is provided with and crosses the oilhole that oily passage communicates.
The tightening device of aforesaid a kind of compensating rope of elevator is characterized in that described cylinder shell upper end is provided with sealing plug.
The tightening device of aforesaid a kind of compensating rope of elevator is characterized in that piston sleeve upper end is provided with crossbeam fixes to be connected and fixed plate.
The beneficial effects of the utility model are: because the effect of damper, when permanent seat when guide rail moves up and down, the compensation of the rope sheave case in tension at any time of restricting, can not only play good damping effect, also has the reduction noise, improve the comfort level of taking elevator, increase the service life of elevator and the effect of guarantee elevator safety operation, therefore have good market outlook.
[description of drawings]
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated;
Fig. 1 is installed in scheme drawing in the hoistway for the utility model;
Scheme drawing when Fig. 2 opens for the utility model control desk;
Fig. 3 is the utility model axonometric drawing;
Fig. 4 is a cutaway view of the present utility model;
[specific embodiment]
As shown in the figure, a kind of tightening device of compensating rope of elevator includes the guide rail 1 that vertically is arranged on the well pit, is fixed on the crossbeam 2 on the pit sidewall, and the upper end of described guide rail 1 and crossbeam 2 fix; On guide rail 1, be provided with and be fixed with rope sheave case 4, counterweight 5 and damper 6 on the described permanent seat 3 along guide rail 1 upper and lower mobile permanent seat 3; Be provided with the compensation rope 7 that two ends are connected with the counterweight framework respectively in the described rope sheave case 4 bottom car; The action of gravity of described counterweight 5 makes the tension of compensation rope.One end of described damper 6 is fixed on the permanent seat 3, and the other end is fixed on the crossbeam 2, when elevator in lifting process, because the mitigation of damper 6 makes tightening device play damping effect.
In the present embodiment, described damper 6 includes base 8, cylinder shell 9, cushion cylinder 10 and piston sleeve 11; Described cylinder shell 9 is arranged on the base 8; Described cushion cylinder 10 is arranged in the cylinder shell 9, and and cylinder shell 9 between have oil storage space 12, described cushion cylinder 10 upper ends are provided with the oilhole 13 that communicates with oil storage space; Described piston sleeve 11 1 ends insert cushion cylinder 10 inside, and are provided with orifice plug 14 in the end, are provided with the cutoff port 15 that communicates with cushion cylinder 10 bottoms in the described orifice plug 14; Formed oily passage 16 between the sidewall of described piston sleeve 11 and the cushion cylinder 10, the sidewall of described piston sleeve 11 is provided with and crosses the oilhole 17 that oily passage communicates.Described cylinder shell 9 upper ends are provided with sealing plug 18.Described piston sleeve 11 upper ends are provided with crossbeam 2 fixes and are connected and fixed plate 19.
