Description
Technical field
The utility model belongs to elevator accessory technical field, is specifically related to a kind of car band rope socketing device of weighing.
Background technology
Fag end combination is used for being connected of elevator rope and car, counterweight and machine room bearing beam, the combination of car fag end is exactly to be used for connecting car and steel rope, in elevator industry years of development, the structural change of fag end combination is little, just ways of connecting has changed, connect by original Babbitt matal casting to become present wedge shape and carve piece and connect, and according to the quantity of elevator wire rope, fag end combination is carried out integrated, make install convenient.
It is to be used for detecting elevator overload in service that car is weighed, fully loaded, semi-load, the underloading situation, the safe operation of elevator is played a very important role.Its principle of work is that LOAD CELLS converts weight signal to electric signal and gives the controller part through transmission cable, partly carries out calculation process by controller, finishes elevator weighing.At the bottom of exhausted big number weighting apparatuss are installed on the car sedan-chair of elevator, elevator rope hitch plate place, elevator crosshead sheave axle place, above the elevator sedan-chair head piece, staircase pedal place etc., be used with controller.
Existing elevator weighing generally uses the Hall type sensor, the Hall type sensor application be electromagnetic induction principle, utilize the variable in distance between sensor sensing plane and the interior cab base plate to obtain the elevator weight variable signal, these characteristics have just determined the accuracy of detection of this type sensor not only to depend on the quality of himself, the influence of cab bottom buffering rubber in also will being subjected to, and yielding rubber in use for some time its elasticity must change, cause the distance between sensor sensing plane and the interior cab base plate to diminish, directly have influence on testing result, cause maintenance times increase in the use.
Still there are some drawbacks in the mounting means of weighting apparatus and the use of sensor.As Hall element being placed on middle part at the bottom of the sedan-chair, weigh up the weight of cab inherence according to the variable in distance of magnetics at the bottom of hall sensing head and the sedan-chair, its weighing results is relevant with sedan-chair bottom buffering caoutchouc elasticity, when yielding rubber after extruding after a while certain compression can take place.Cause Hall element and magnetics distance to change, cause the load of elevator more and more littler, influence accuracy of detection.
The utility model content
The purpose of this utility model is: the car band that provide a kind of precision height, favorable repeatability, simple installation, is easy to the safeguard rope socketing device of weighing.
The purpose of this utility model is achieved in that the car band rope socketing device of weighing, comprise framework, the bottom of described framework fixedly installs at least two hitch rods, the middle part of described framework fixedly installs slack rope and re-packs, the end that described slack rope re-packs is hinged the switch end that re-packs, the described switch other end that re-packs connects switch, the sidewall of described framework is provided with opening, the side of described framework fixedly installs the fag end adapter plate, described fag end adapter plate is arranged in the opening of frame side wall, the top of described framework fixedly installs the bridge-type strain-ga(u)ge transducer that is provided with groove, and the upper end of described fag end adapter plate is arranged in the groove of bridge-type strain-gauge.
The utility model is installed in the bridge-type strain-ga(u)ge transducer on the rope hitch plate, according to physics principle: a plane has some stressed simultaneously, its center of gravity necessarily drops within the polygon of this some composition, so my company is placed on sensor between each fag end, can not change as the long-term use comfort.Drag when elevator and to draw when being 1: 1, the weight that sensor bore is the weight (1: 1) of whole cab, drags when elevator and draws when being 2: 1, and what sensor bore is the weight of 1/2 cab.Can measure because added weights such as elevator compensating chain, trailing cable change with the different elevator deadweights that produce of elevator parking stop.
The characteristics of bridge-type strain-ga(u)ge transducer are: weigh and the independent control use of torque compensation employing, have compensate function successively; Instrument is shown as weight in the elevator cage when promptly weighing, and compensation value is the weight of bearing in the elevator cage, and the weight summation of generations such as collet cable, compensated chain, traction steel-cable and track friction resistance offers frequency converter, make elevator more accurately, smooth operation.
The beneficial effects of the utility model are: survey precision height, favorable repeatability, simple installation, be easy to safeguard, have bigger overload scope.
As a kind of improvement of the present utility model, described bridge-type strain-ga(u)ge transducer comprises overhead guard, sensor, effector, wool pad, rubber pad, metal platen, described sensor, effector, wool pad, rubber pad, metal platen are arranged in the gap between described overhead guard and the fag end adapter plate, the upper end of described fag end adapter plate is provided with sensor, the top of described sensor is provided with effector, the top of described effector is provided with wool pad, the top of described wool pad is provided with rubber pad, and the top of described rubber pad is provided with metal platen.
