Description
Technical field
This utility model relates to hydropower gate machine control system, especially relates to hydropower gate machine walking total travel Precise Position System.
Background technology
The main task of water-control project is generating, flood discharge, water supply irrigation etc., and power station is provided with the diversion tunnels such as power tunnel, flood discharging tunnel, irrigation tunnel, and owing to diversion tunnel is more, hydraulic structure is up to hundreds of meters.The import of diversion tunnel is provided with trash rack, maintenance door, gate and the equipment such as grab bucket of removing contamination, and the gantry gate hoists (being called for short: door machine) operating these equipment to come and go operation along track on the hydraulic structure that hundreds of rice is long.When the gate of door certain diversion tunnel of confidential lifting, need first to run above the gate slot of this gate, adjust the position of door machine the most back and forth, after making the hanger centering location hanging head and gate of a machine, then with hanging axis, they are coupled together, finally gate is sling and transport or put into gate slot, its job order is: combustion adjustment location is worn axle lifting and run, so to be run to operating position rapidly by door machine, and adjust location exactly, not easy.When gate does not works, generally it is locked on inspection platform, inspection platform is located in the hydraulic structure below dam crest, in hydraulic structure rather dark, in addition door machine operator limited view in drivers' cab, cannot be clearly observed the accurate location of gate lifting eye, all can only rely on the commander of surface personnel to operate a machine at all.Therefore, in the work process of whole door machine, wear the location of the adjustment before axle wastes time and energy very much.
Summary of the invention
This utility model purpose is to provide a kind of hydropower gate machine walking total travel Precise Position System.
For achieving the above object, this utility model takes following technical proposals:
Hydropower gate machine described in the utility model walking total travel Precise Position System, including the door machine being arranged on hydraulic structure track, in the wheel hub end of described door machine travelling mechanism, absolute rotary encoder is installed, the door frame of door machine is provided with proximity transducer；The signal output part of described absolute rotary encoder and proximity transducer is electrically connected by the PLC electrical control cabinet signal input part of signal cable with door machine respectively；Side along described hydraulic structure track is provided with the many groups of positioning components being made up of three metal inductors, described often group positioning component lays respectively at above a gate of correspondence and along the transversely arranged setting of this gate, and middle metal inductor is positioned at the midline position of corresponding gate.
The driving motor of described door machine travelling mechanism is frequency control motor.
This utility model advantage is to improve automatization level and the work efficiency of hydraulic structure door machine; realize the long-range control of door machine; make full use of the frequency control function of a machine travelling mechanism; with absolute rotary encoder, proximity transducer, positioning component with the use of; achieve a machine by the most quickly running near operating position; slow down the most again, automatic accurate shutdown after eventually arriving at operating position.Door machine quickly runs the time of having saved, and improves work efficiency, and slow down is that the operation inertia of reduction door machine, raising location accuracy provide guarantee before shutting down location, it is ensured that it is safe efficient, accurate that door machine runs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, hydropower gate machine described in the utility model walking total travel Precise Position System, including the door machine 2 being arranged on hydraulic structure track 1, the driving motor of door machine travelling mechanism is frequency control motor, axle ends at door machine travelling mechanism adhesion wheel 3 is provided with absolute rotary encoder 4, and the door frame of door machine 2 is provided with proximity transducer 5；The signal output part of absolute rotary encoder 4 and proximity transducer 5 is electrically connected by the PLC electrical control cabinet signal input part of signal cable with door machine 2 respectively；Side along hydraulic structure track 1 is provided with the many groups of positioning components being made up of three metal inductors 6.1,6.2,6.3, often group positioning component lays respectively at above a gate 7 of correspondence and arranges along the horizontal rods arranged in horizontal line of this gate 7, and middle metal inductor 6.2 is positioned at center line 8 position of corresponding gate 7.
Absolute rotary encoder 4 and adhesion wheel 3 wheel shaft coordinated testing rotating cycle, the range ability being responsible for opposite house machine 2 measures and record, and the operating range of opposite house machine 2 and position have power failure memory function.Proximity transducer 5 coordinates with three the metal inductors 6.1,6.2,6.3 often organizing positioning component; it is responsible for after door machine 2 arrives setting position, sending instruction and then changing the travel speed of door machine 2; middle metal inductor 6.2 is used for shutting down location, and two metal inductors 6.1,6.3 of both sides are used for slowing down.
As it is shown in figure 1, when door machine 2 needs the gate 7 lifting by crane No. two tunnels, door machine 2 operator press No. two start buttons, door machine 2 quickly runs to No. two tunnels, and now absolute rotary encoder 4 works, and proximity transducer 5 shields, and door machine runs the most forward；When door machine 2 run L1 apart from after (near No. two hole gates, the distance that i.e. absolute rotary encoder 4 sets away from metal inductor 6.1), absolute rotary encoder 4 sends instruction, and work opened by proximity transducer 5, and door machine 2 continues the most quickly to run；After proximity transducer 5 overlaps with metal inductor 6.1, proximity transducer 5 sends deceleration instruction makes a machine 2 by quickly running the slow running being changed into setting；After proximity transducer 5 overlaps with middle metal inductor 6.2, proximity transducer 5 sends cutoff command, and door machine stops and positions.
Equally, when door machine 2 needs the gate 7 lifting by crane No. three tunnels, door machine 2 operator press No. three start buttons, and door machine 2 quickly runs to No. three tunnels, and now absolute rotary encoder 4 works, and proximity transducer 5 shields, and door machine runs the most forward；When door machine 2 run L2 apart from after (near No. three hole gates, the distance that i.e. absolute rotary encoder 4 sets away from metal inductor 6.1), absolute rotary encoder 4 sends instruction, and work opened by proximity transducer 5, and door machine 2 continues the most quickly to run；After proximity transducer 5 overlaps with metal inductor 6.1, proximity transducer 5 sends deceleration instruction makes a machine 2 by quickly running the slow running being changed into setting；After proximity transducer 5 overlaps with middle metal inductor 6.2, proximity transducer 5 sends cutoff command, and door machine stops and positions.
Between the distance set on the right side of the distance set on the left of metal inductor 6.1 and metal inductor 6.3, constitute the work section L3 of proximity transducer 5, for the location of running slowly and stop of the positive and negative both direction of door machine 2.
