Abstract

An elevator ceiling wheel arrangement comprising: roof beam, car stand, damper, cross arm weldment return the rope sheave, car frame is constituteed with the car stand to the car roof beam, damper sets up between cross arm weldment and the car roof beam, the cross arm weldment sets up two, it sets up two to return the rope sheave, it sets up between two cross arm weldments to return the rope sheave, and set up in the both ends of cross arm weldment, through above-mentioned design, its technological effect is as follows: the design of two rope pulleys that return for the bearing capacity that single rope pulley received reduces half, simultaneously, makes the cornerite of driving sheave increase in the computer lab, avoids the car phenomenon of skidding.

Description

Elevator car top wheel arrangement structure

Technical Field

The utility model relates to an elevator car technical field, in particular to elevator cab wheel arrangement structure.

Background

In medium and high speed elevator, its travelling comfort and security are the very important part, and the traction sheave drives the lift car in-process, has following problem: (1) after the return rope wheel runs for a period of time under long time and high load, in general, because only one return rope wheel is arranged, the load of the return rope wheel is large, the phenomenon of slipping of the return rope wheel is easy to occur, and once the return rope wheel occurs, the comfort of passengers is greatly reduced; (2) the vibration problem brought by the traction sheave in the traction process also brings bad experience to passengers; (3) the return rope wheel may have a risk of impurities falling in, thereby causing a safety hazard.

Disclosure of Invention

For solving the technical problem, the utility model aims at providing an elevator sedan-chair top wheel arrangement structure returns the rope sheave design through two to and corresponding shock attenuation, enhancement, closed design, make the bearing capacity that the rope sheave received that singly returns halve, and stopped the rope phenomenon of skidding, make simultaneously to return the reinforcing of rope sheave assembly intensity, and impurity can not fall into, adopt technical scheme as follows.

An elevator ceiling wheel arrangement comprising: the car is put beams in place, the car stand, and damper assembly, the cross arm weldment returns the rope sheave, car skeleton is constituteed to the car is put beams in place and the car stand, damper assembly sets up between cross arm weldment and the car is put beams in place, the cross arm weldment sets up two, it sets up two to return the rope sheave, return the rope sheave and set up between two cross arm weldments, and set up in the both ends of cross arm weldment.

Preferably, damper includes cylindrical shock pad and shock attenuation steel sheet, two upper and lower faces of cylindrical shock pad all set up the shock attenuation steel sheet, eight are no less than to cylindrical shock pad quantity.

Preferably, the cross arm weldment is of a channel steel structure, notches of the cross arm weldment are designed to be opposite to each other, reinforcing ribs are arranged in the channel steel, and the number of the reinforcing ribs is at least three.

Preferably, the exposed part of the rope return wheel is respectively shielded by an upper cover plate, a lower cover plate and a side cover plate, and one side of the rope return wheel is also provided with a rope blocking plate.

Through the design, the technical effects are as follows: (1) the double-return rope wheel design reduces the bearing force borne by a single return rope wheel by half, and simultaneously increases the wrap angle of a traction wheel in a machine room to avoid the phenomenon of slipping of a lift car; (2) the cross arm weldment adopts a design that a double-groove steel notch faces the outer box bottom, and reinforcing ribs are arranged, so that the strength of the return rope wheel assembly is greatly improved; (4) the damping assembly is used, so that the damping capacity of the return rope wheel is greatly improved, and the comfort level of passengers is improved; (5) the application of the peripheral cover plate of the return rope wheel avoids the chance that impurities fall into the return rope wheel.

Detailed Description

The technical solution of the present invention will be described in detail with reference to the specific embodiments, it should be understood that these embodiments are only used for illustrating the present invention and are not used for limiting the scope of the present invention, and after reading the present invention, the modifications of the present invention in various equivalent forms by those skilled in the art all fall into the scope defined by the claims attached to the present application.

Example 1

An elevator ceiling wheel arrangement, as shown in fig. 1, 2 and 3, comprising: the car upper beam 1, the car upright post 2, the shock absorption assembly, the cross arm weldment 8 and the return rope wheel 5, wherein the car upper beam 1 and the car upright post 2 form a car framework, the shock absorption assembly is arranged between the cross arm weldment 8 and the car upper beam 1, the cross arm weldment 8 is provided with two, the return rope wheel 5 is provided with two, and the return rope wheel 5 is arranged between the two cross arm weldments 8 and is arranged at two ends of the cross arm weldment 8;

the damping assembly comprises a cylindrical damping pad 3 and damping steel plates 10, the damping steel plates 10 are arranged on the upper surface and the lower surface of the cylindrical damping pad 3, and the number of the cylindrical damping pads 3 is not less than eight;

the cross arm weldment 8 is of a channel steel structure, notches of the cross arm weldment are designed to be opposite to each other, reinforcing ribs 9 are arranged in the channel steel, and the number of the reinforcing ribs 9 is at least three;

the exposed part of the rope return wheel 5 is respectively shielded by an upper cover plate 4, a lower cover plate 7 and a side cover plate 6, and one side of the rope return wheel 5 is also provided with a rope blocking plate 11.

Through the design, the technical effects are as follows: (1) the double-return rope wheel design ensures that the bearing force borne by the single return rope wheel 5 is halved, and simultaneously, the wrap angle of a traction wheel in a machine room is increased, so that the phenomenon of slipping of a lift car is avoided; (2) the cross arm weldment 8 adopts a double-groove steel notch design towards the outer box bottom, and is provided with the reinforcing ribs 9, so that the strength of the return rope wheel assembly is greatly improved; (4) the damping assembly is used, so that the damping capacity of the return rope wheel is greatly improved, and the comfort level of passengers is improved; (5) the application of the peripheral cover plate of the return rope wheel 5 avoids the possibility that impurities fall into the return rope wheel.
