Description
Technical field:
The present invention relates to a kind of device that detects the bucket wheel machine luffing angle on the employed bucket wheel machine equipment in a kind of stock ground that is applied in industrial enterprises such as harbour, metallurgy, electric power, coal, building materials.
Background technology:
At present, at the harbour, the boom type bucket wheel stacker of the whole hydraulic pressure pitching pattern used of the stock ground of industrial enterprises such as metallurgy, electric power, coal, building materials develops towards automatic program control, if will finish the bucket wheel machine automatic program control, the angle state signal of bucket wheel machine luffing mechanism must offer the programmable controller of bucket wheel machine, and programmable controller is called for short PLC (PLC is the abbreviation of English Program Logic Control).Owing to require to adopt the programmed control maneuvering device, this just requires bucket wheel machine to want to detect angular signal automatically when doing the pitching action.But because the pitching on bucket wheel machine top is to finish round the hinge of a fixing hinge.This feasible method of the corner of conventional detection axle of using can not be finished this testing.This has influenced bucket wheel machine and has realized the programmed control manipulation.Therefore, develop a kind of device that detects the bucket wheel machine luffing angle is new problem anxious to be solved always.
Summary of the invention:
The object of the present invention is to provide a kind of boom type bucket wheel stacker for whole hydraulic pressure pitching pattern, the pitching on its complete machine top is a kind of device that detects the bucket wheel machine luffing angle of finishing round the hinge of a fixing hinge.
The object of the present invention is achieved like this: a kind of device that detects the bucket wheel machine luffing angle, whole device is by mandrel, first nut, screw, the U-shaped body, scrambler, little minor axis, holding screw, copper sheathing, bearing, the bolt pair, the mounting hole support, fork, second nut, fixing hinge, frame is formed, utilize screw thread to be screwed into the fixedly axle head of hinge mandrel, and mandrel is equipped with tight with first nut, make mandrel and fixedly hinge be one, be milled with two planes in the outer radius symmetry of mandrel and be screwed the U-shaped body, scrambler is fixed on the U-shaped body, the rotatable axle of scrambler has an endoporus, one end of this endoporus and little minor axis is fixed with holding screw, the other end of little minor axis and the copper sheathing in the mandrel form clearance fit, the bearing scene is welded on the frame of bucket wheel machine and by the secondary fixedly mounting hole support of bolt, when the pitching of bucket wheel machine frame, waist hole support just can drive fork, and fork is to be fixed on the little minor axis by second nut; The effect of bucket wheel device is to take material by the swiveling wheel bucket, owing to will take the material of differing heights, the frame at bucket wheel device place will be rotated pitching round fixing hinge, when swinging, can fork the axle rotation of editor's code pressing device by little minor axis band, import owing to relatively rotating the pulse signal that produces to the PLC of bucket wheel machine main frame, how much being directly proportional of number of pulses with the angle of rotating, after PLC accepts pulse signal, just satisfied the programme controlled condition of bucket wheel machine, utilization is fixed on the bearing on the bucket wheel machine pitching frame, have the mounting hole support and stir fork, make and the rotating shaft rotation of scrambler obtain the rotating shaft of scrambler and relatively rotating of scrambler; The short hole pitch-row that has the waist hole of mounting hole support equates that with the diameter of fork when having the rotation of mounting hole supporting band movable pendulum bar, because of it is the minor face drive fork of waist shape, the two can not produce the gap, promptly can not produce stagger; And simultaneously because alignment error appears at the slotted hole direction of support mounting hole, the mounting hole support can also be eliminated the error of bringing is installed.
Main points of the present invention are its structure and principle of work.Its principle of work is: for the boom type bucket wheel stacker of whole hydraulic pressure pitching pattern, the pitching on its complete machine top is to finish round the hinge of a fixing hinge.Because the hinge of this hinge is fixed, this feasible method of the corner of conventional detection axle of using can not be finished this testing.And to finish the corner that bucket wheel machine programmed control mode of operation must detect the bucket wheel machine pitching.Detect the corner of bucket wheel machine pitching, at first, utilize parts such as screw thread fixed central spindle, U type body, scrambler in the fixing center of hinge axle head; Next part such as hold-down support, support, fork, little minor axis on the bucket wheel frame, the rotating shaft endoporus of little minor axis and scrambler is fixed together.Because the frame of bucket wheel machine has luffing, so can make the rotating shaft of scrambler and scrambler produce relative rotation, this relatively rotates the meeting output pulse signal, finishes the detection and the output of angular signal.
A kind of device that detects the bucket wheel machine luffing angle compared with prior art, has boom type bucket wheel stacker for whole hydraulic pressure pitching pattern, the pitching on its complete machine top is advantage such as to finish round the hinge of a fixing hinge, will be widely used in harbour, metallurgy, electric power, coal, the building material industry.
