Abstract

The utility model relates to a detecting device for bridge type cranes, which belongs to the field of detecting crane positions; the utility model is suitable for detecting positions of bridge type cranes; an approaching inductive switch 3 is arranged on a switch lower cover plate 1 of an end beam of the bridge type crane, a metal inductive sheet 4 is arranged at the position of the edge part of a big track 2 of the bridge type crane, and the position corresponds to that of being detected; the utility model uses the principle of electromagnetic induction to automatically complete detecting the position of the bridge type crane, and an electronic scale of the bridge type crane in various workshops can automatically measure materials according to positions; the utility model has the advantages of simple device and strong interference resistance ability.

Description

The crane in bridge type position detecting device

The utility model is a kind of crane in bridge type position detecting device, belongs to hoisting crane position probing field, is applicable to all kinds of crane in bridge type position probing.

For a long time, the data acquisition of crane in bridge type electronic scales is an insoluble problem always, and detects particularly difficulty of crane in bridge type run location location metering automatically; For the location metering of the employed crane in bridge type electronic scales of steelshop, because the abominable difficulty of steelshop environment is bigger.And detection crane in bridge type run location, thereby make crane in bridge type electronic scales opsition dependent automatic gauge material be related to this problem in the inputoutput of the material of different operations in the production practice, the accounting of cost, particularly STEELMAKING PRODUCTION and relate to the stable of steel-making controlling level and quality.

The purpose of this utility model is to provide a kind of crane in bridge type position detecting device, and this device is applicable to the crane in bridge type position probing of all kinds of workshops, is particularly useful for the location metering of the crane in bridge type electronic scales under the steelshop harsh environment.

The purpose of this utility model is achieved in that

The utility model utilizes electromagnetic induction principle, the non-contact detection probe is installed in the end girders of overhead traveling crane bottom, and in the position that bridge crane track limit portion will detect sheetmetal is installed.When crane in bridge type travels when putting in place, detection probe is sent signal to transmitter, and transmitter is sent into from the radio station after with signal conditioning, sends into computing machine through control station and carries out data handing.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the scheme drawing of end girders of overhead traveling crane and crane track.

Fig. 2 is that the A of Fig. 1 is to view.

Fig. 3 is a fundamental diagram of the present utility model.

Crane in bridge type position detecting device of the present utility model is to be equipped with near inductive switch 3 on the end carriage lower cover 1 of crane in bridge type, corresponding to the position that will detect metal sensing chip 4 is installed in the limit of bridge crane track 2 one.

Its working process is: when crane in bridge type travels near the detection position, be installed in approaching with the metal sensing chip 4 in the limit portion that is installed in bridge crane track 2 on the end carriage lower cover 1 of crane in bridge type this moment near inductive switch 3, at this moment in metallic object, produced eddy current, to such an extent as to thereby the energy that has absorbed vibration makes oscillation amplitude weaken failure of oscillation, makes near the inductive switch counter-rotating and forms binary switched electrical signal.This electric signal is delivered to on-the-spot radio station after being handled by the signal transmitting device by the detection position, delivers to key station by on-the-spot radio station through wireless telecommunications, sends into center industrial computer (computing machine) again and carries out data handing.

The utility model can be finished the position probing of crane in bridge type automatically, especially solved the steelshop harsh environment (high temperature, forceful electric power, strong magnetic, by force shake and dense smoke) Position automatic detection of crane in bridge type down, thereby make the crane in bridge type electronic scales in all kinds of workshops can opsition dependent automatic gauge material.Solved the measuring cost examination of each inter process of workshop, made production control that data accurately and reliably arranged.The utility model is employed near inductive switch and metal sensing chip, have no touch, no pressure, no spark, and can send rapidly detection signal and highly sensitive, high temperature resistant, frequency fast and the precision advantages of higher, and this device is simple, and antijamming capability is strong, is easy to apply.

Claims

1, a kind of crane in bridge type position detecting device is characterized in that being equipped with near inductive switch (3) on the end carriage lower cover (1) of crane in bridge type, corresponding to the position that will detect metal sensing chip (4) is installed in the limit portion of bridge crane track (2).
