Abstract
The invention discloses a shoulder-bag type car frame system on an elevator. The system comprises a lift car and a car frame, wherein the car frame is used for supporting the lift car and comprises two vertical beams and an upper beam; the two vertical beams are arranged on one side of the lift car simultaneously and also arranged on other two opposite sides of the lift car respectively; the upper beam is arranged between the two vertical beams and above the lift car; the upper beam comprises a main upper beam and an auxiliary upper beam; the two end parts of the main upper beam are connected to the two vertical beams respectively; the auxiliary upper beam is vertically arranged in the middle of the main upper beam and faces the lift car; the auxiliary upper beam is provided with a rope sheave; the direction of the axial lead of the rope sheave is vertical to that of the symmetrical central line of the two vertical beams; and a hoisting rope is wound on the rope sheave downwards, wherein the movement velocity of the hoisting rope is two times that of the lift car, namely the rope winding ratio is 2 to 1. Due to the arrangement of the rope sheave, moment generated when the rope sheave is wound by the hoisting rope can be basically counteracted by unbalance loading moment generated when a guide shoe is pressed in a guide rail by a car frame system in the horizontal direction, so that the applied force between the guide shoe and the guide rail in the horizontal direction can be reduced or eliminated, the abrasion of the guide shoe can be reduced, and the comfortable feeling when a person is in an elevator is improved by balancing the moment generated by the unbalance loading of the elevator.

In the lift facility, existing Backpack type crane bridging system, comprise car, be used to support the sedan-chair frame of car, the sedan-chair frame comprises two upright beams that are arranged on car one side simultaneously, be arranged between two upright beams and be positioned at the upper beam of car top, be arranged between two upright beams and be positioned at the underbeam of car below, these two upright beams lay respectively at the other relative both sides of car, carriage is installed on the underbeam, be placed with car on this carriage, the base plate of carriage and car is fixedly connected, upper beam is provided with the clamping unit that is stuck on the car top board, this clamping unit is used for fixing the position of car, the upper and lower end parts of upright beam is provided with leads boots, leading boots matches with guide rail, be used to guide crane bridging system to carry out dipping and heaving along guide rail, guide rail is installed in the elevator hoistways by support, the middle part of putting the beams in place is connected with an end of hauling rope, hauling rope is walked around traction sheave, the other end counterweight of ining succession, friction force on dependence hauling rope and the traction sheave between the grooving drives the car lifting, the kinematic velocity of hauling rope is identical with the rising or falling speed of car, be that the wiring ratio is 1: 1, on elevator with this Backpack type crane bridging system, because the direction of the line of centers of crane bridging system is to depart from the force direction that is subjected to of crane bridging system, having bigger application force will lead boots in the horizontal direction during the crane bridging system lifting like this is pressed on the guide rail, boots are led in wearing and tearing easily, especially when the car unbalance loading is serious, it is severe to lead the boots wearing and tearing, need often to change to lead boots, and the comfort level of elevator ride is poor.
Summary of the invention
Thereby providing, the object of the invention a kind ofly comes the stressed Backpack type crane bridging system that reduces to lead the boots wearing and tearing and improve ride quality of balance car and sedan-chair frame by rope sheave is set.
For achieving the above object, the technical solution used in the present invention is: Backpack type crane bridging system on a kind of elevator, comprise car, be used to support the sedan-chair frame of described car, described sedan-chair frame comprises two upright beams that are arranged on described car one side simultaneously, be arranged between described two upright beams and be positioned at the upper beam of described car top, be arranged on the underbeam between described two upright beams, described two upright beams lay respectively at the other relative both sides of described car, described upper beam comprises that both ends are connected the Your Majesty's beam on described two upright beams respectively, be vertically set in the middle of described Your Majesty's beam and towards the auxilliary upper beam of described car, described auxilliary upper beam is provided with rope sheave, and the symmetrical center line of the direction of axis line of described rope sheave and described two upright beams is perpendicular.
Preferably, the axial line of described rope sheave parallels setting with described Your Majesty's beam.
As a kind of concrete embodiment, described underbeam is provided with carriage, and described carriage is held the base plate of described car, and described upper beam is provided with clamping unit, and this clamping unit blocks the top board of described car.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage: be arranged on the rope sheave on auxilliary the upper beam and walked around hoist ropes downwards, hoist ropes drives car by rope sheave and the sedan-chair frame moves along lifting rail, the kinematic velocity of hoist ropes is 2: 1 with the ratio of the kinematic velocity of car, be that the wiring ratio is 2: 1, by rope sheave is set, hoist ropes is walked around moment that rope sheave produces and can will be led boots with crane bridging system and be pressed in unbalance loading moment basic neutralisation in the horizontal direction on the guide rail, can reduce like this or eliminate the application force of leading horizontal direction between boots and the guide rail, reduction is to leading the wearing and tearing of boots, by the moment that can balance elevator unbalance loading produces, improved the comfort of elevator ride.
Description of drawings
Accompanying drawing 1 is looked scheme drawing for the master of sedan-chair frame among the present invention;
Accompanying drawing 2 is the schematic side view of sedan-chair frame among the present invention;
Accompanying drawing 3 is for having the schematic side view of elevator of the present invention.
The specific embodiment
Further set forth structure of the present invention below in conjunction with accompanying drawing.
Referring to Fig. 1-3, Backpack type crane bridging system on a kind of elevator, comprise car 1, be used to support the sedan-chair frame 2 of car 1, sedan-chair frame 2 comprises two upright beams 3 that are arranged on car 1 one sides simultaneously, be arranged between two upright beams 3 and be positioned at the upper beam 4 of car 1 top, be arranged on two underbeams between the upright beam 3, two upright beams 3 lay respectively at the other relative both sides of car 1, underbeam is provided with carriage 9, carriage 9 is held the base plate of car 1, upper beam 4 comprises that both ends are connected two Your Majesty's beams 6 on the upright beam 3 respectively, be vertically set in the middle of Your Majesty's beam 6 and towards the auxilliary upper beam 7 of car 1, auxilliary upper beam 7 is provided with rope sheave 8, and the symmetrical center line of the direction of axis line of rope sheave 8 and two upright beams 3 is perpendicular.The end of stretching out on the auxilliary upper beam 7 is provided with clamping unit 10, and this clamping unit 10 blocks the top board of car 1, fixes by last underbeam and supports car 1.
