Description
Technical field
The invention discloses a kind of cage guide end face distance meter and measuring method.
Background technology
Under the background of modern economy fast development, the application of elevator is more and more extensive, while its security performance is constantly by public concern, people to the ride quality of elevator, as smoothness, comfort level etc. index it is also proposed more and more higher requirement.The factor affecting elevator ride comfort level mainly comprises vibration up and down in elevator cage operation process and double swerve.
Lift car is in the process run up and down along guide rail, and the change of two guide rail end face distances must not exceed setting, otherwise lift car double swerve can be made excessive, affects comfort level, even can cause derailing, cause accident.Elevator inspection related specifications requires that mostly the deviation of guide rail end face distance is within ± 2mm, be in practice examining work to carry out measuring distance with tape measure.This measuring method precision is low, can not continuous coverage, the also easy impact by narrow and small hoistway space.
Summary of the invention
The present invention conveniently elevator reviewer professionally measures, and reduces movement range at sedan-chair top space measurement to reduce potential danger, discloses a kind of pointer disc type guide rail end face distance meter and measuring method.
The technical solution used in the present invention is as follows:
Cage guide end face distance meter, comprises measuring instrument body and extension rod;
Described measuring instrument body comprises a display disc, the pointer that three energy rotate around its central point is fixed with in the center of described display disc, wherein being positioned at middle pointer is power pointer, two root pointers being positioned at both sides are non-powered pointer, and power pointer provides power by the elastic device that is connected with extension rod, non-powered pointer is under the driving of power pointer, passive offsets along the direction that power pointer drives, and the angle of two non-powered pointer formation is cage guide end face distance.
Further, described elastic device is a spring, and one end of spring is connected with extension rod, and the other end is connected with the power pointer of display disc.
Further, the on-fixed end of described power pointer is provided with a short column, described short column is for stirring the non-powered pointer of both sides, change at spring end position in the swing process caused, power pointer can according to the variation of spring, back rotation is carried out along display disc, during rotation, the non-powered pointer on both sides can be pulled out and move, the non-powered pointer on both sides is forced to rotate, the position that non-powered pointer finally indicates is exactly the maximum position of the swing deflection of middle pointer, the i.e. ultimate range of cage guide end face, the angular deviation of non-powered pointer must not be added and is greater than 4mm, if be greater than 4mm, then this elevator is defective.
Further, the part that described extension rod connects measuring instrument body is provided with pilot hole, when measuring the guide rail end face of different mounting distance, can according to the distance register pin of guide rail end face by extension rod location in place, extension rod will ensure that spring is at pressured state behind location.
Further, one end of described extension rod is connected with spring, and the other end is connected with roller I, and described roller I can slide up and down along cage guide I.
Further, the side of described display disc is stuck on cage guide I by spring, extension rod and roller I, and relative opposite side directly connects a roller II by a connecting link, and described roller II slides up and down along the cage guide II of this side.
The non-central location of described display disc between two guide rails, because elevator is in lifting process, the wire rope of its lifting is all arranged on the center of two guide rails, and in order to the impact not by wire rope, display disc is arranged at the non-central location of the centre of two guide rails by the application.
Measuring method of the present invention is as follows:
During the work of this device, between two guide rails placing it in elevator, extension rod is located in place by the distance register pin according to guide rail end face, extension rod will ensure that spring is at pressured state behind location, then the roller of these device both sides slides up and down along the guide rail of elevator, because the distance between two guide rails is not steady state value, therefore, in the process that spring moves at whole device, its end position constantly changes, power pointer can according to the variation of spring, back rotation is carried out along display disc, during power indicators turn, the non-powered pointer on both sides pulls out and moves by the short column on it, the non-powered pointer on both sides is forced to rotate, when roller slides up and down two guide rails distance maximum positions along the guide rail of elevator, the deflection of non-powered pointer also can reach maximum, the position of final non-powered pointer instruction is exactly the maximum position of the swing deflection of middle pointer, the i.e. ultimate range of cage guide end face, according to the production standard of current elevator, range deviation between two guide rails can not be greater than 4mm, therefore, as long as the angular deviation of non-powered pointer is added be greater than 4mm, then, this elevator is defective, if be less than or equal to 4mm, then this elevator is qualified.
Beneficial effect of the present invention is as follows:
When the present invention uses, only need this device card in the guide rail of elevator, then this device moves up and down along guide rail, the position that non-powered pointer finally indicates is exactly the maximum position of the swing deflection of middle pointer, the i.e. ultimate range of cage guide end face, make elevator reviewer carry out when specialty is measured so convenient, reduce movement range at sedan-chair top space measurement to reduce potential danger.
