Abstract

The utility model relates to the technical field of an elevator and provides a balance adjustment device for an elevator lift car. The balance adjustment device for the elevator lift car comprises a supporting frame and a clump weight; the supporting frame is arranged at the bottom of the lift car; the supporting frame is ring-shaped; the circle center of the supporting frame is positioned on the center line of the bottom surface of the lift car; a rotating shaft is vertically arranged at the center position of the bottom surface of the lift car; the lower end of the rotating shaft is connected with an oscillating bar; one end of the oscillating bar is fixed or hinged with the rotating shaft; a roller is arranged at the other end of the oscillating bar; the roller is positioned on the ring-shaped plane of the supporting frame; the roller can perform the circular motion in the ring-shaped plane of the supporting frame around the rotating shaft; and the clump weight is movably hung on the oscillating bar. By the structure, the clump weight carries out balance regulation on the lift car in the range of the integral supporting frame.

Description

The lift box balance control apparatus
Technical field
The utility model relates to the elevator technology field, particularly a kind of lift box balance control apparatus.
Background technology
Elevator is subjected to force unbalance if there is car in operational process, then elevator lead boots and other parts discontinuity, affect service life.Unbalanced lift car is in operation also can produce vibration and noise, and environment is taken in impact.For head it off, be in the car bottom a fixing erecting frame to be set in the prior art, hang clump weight at erecting frame, when elevator used, according to the stressing conditions of leading boots, the position of self-balanced upper rotary made the stress balance of leading boots.But because erecting frame is for fixing, clump weight can only carry out single direction mobilely regulates stressedly, and setting range is limited.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of lift box balance control apparatus, in the scope of whole bracing frame car is carried out balance adjustment in the hope of making clump weight.
The technical scheme that the utility model is taked is:
A kind of lift box balance control apparatus, comprise bracing frame and clump weight, support frame as described above is arranged on the bottom of car, it is characterized in that, support frame as described above is annular, its center of circle is positioned on the line of centers of bottom surface of described car, center in the bottom surface of described car vertically arranges a rotating shaft, lower end in described rotating shaft connects a fork, one end of described fork fixes with described rotating shaft or twisted branch is connected, and the other end of described fork arranges a roller, and described roller is positioned on the planar annular of bracing frame, described roller can move in a circle around the planar annular of described rotating shaft at support frame as described above, and described clump weight is removable to be hung on the described fork.
Further, the rotation of described rotating shaft and the movement of clump weight provide power by motor, the boots place that leads at car arranges force checking device, the control system of elevator is according to described stressing conditions of leading boots, drive the rotation of described rotating shaft and the movement of described clump weight and make clump weight move to suitable position, make the described boots stress balance of leading.
Further, at the planar annular of support frame as described above rolling groove is set, described roller rolls in described rolling groove.
The beneficial effects of the utility model are:
By the rotation of fork and the movement of clump weight, in whole bracing frame scope car is regulated;
By before the elevator operation position of clump weight is regulated at every turn, after leading boots force bearing adjustment balance, the operation elevator reduces vibration and noise in the cage operation.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is that A in the accompanying drawing 1 is to view.
Mark in the accompanying drawing is respectively:
1. steel rope; 2. car;
3. bracing frame; 4. roller;
5. fork; 6. rotating shaft;
7. clump weight.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model lift box balance control apparatus.
Referring to accompanying drawing 1,2, car 2 carries out lifting by steel rope 1 traction, bottom at car 2, bracing frame 3 is installed, bracing frame 3 is annular, the width of the diameter of annular outer ring and car 2 approaches, bracing frame 3 is installed in the middle of the bottom surface of car 2, its center of circle is positioned on the line of centers of bottom surface of car 2, rotating shaft 6 is vertically installed in center in the bottom surface of car 2, and the lower end of rotating shaft 6 is fixed or twisted branch connects fork 5, one end of fork 5 links to each other with rotating shaft 6, the other end is installed a roller 4, and the position of roller 4 is on the planar annular of bracing frame 3, and roller 4 can rotate by axle centered by rotating shaft 6, planar annular at bracing frame 3 arranges rolling groove, and roller 4 rolls in rolling groove.The position of fork 5 is level, and clump weight 7 mobile cranes hang on the fork 5, and when roller 4 rotated, clump weight 7 was driven together by fork 5 and 6 rotates around the shaft.
Rotating shaft 6 is by motor-driven rotation, belt is set or chain makes clump weight make traveling priority along fork 5 at fork 5, and the power of belt or chain also can be provided by motor.Motor is by the control system control of elevator, the boots place that leads at elevator is provided with force checking device, force checking device is for detection of the stressing conditions of leading the boots place, lead stressed the stressed of car 2 that reflect at boots place, control system is according to the feedback of force checking device, and control motor-driven fork 5 rotates, and drives belt or chain and rotates, make clump weight 7 move to suitable position, to the stressed balance of carrying out of car.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
