Description
Technical field
The utility model relates to a kind of test devices of brake, and in particular to arrive a kind of brake tightness pressure test
Auxiliary test unit.
Background technique
Brake is a kind of indispensable key device of turbine-generator units, it is main, and there are two effects: first, sending out
During motor stopping, when revolving speed is reduced to the 30%~40% of rated speed, is continuously braked, made for generator amature
Unit can be shut down rapidly；Second, jacking up rotor using high pressure oil in unit maintenance and installation process.Brake quality
Superiority and inferiority will directly affect the overall performance index of turbine-generator units, so must carry out tightness pressure resistance to it in a pre-installation
Test the quality to check product.Generally doing the conventional method of tightness pressure test is that will directly live in cavity of resorption cut-in pressure oil
Then at top to upper cylinder cover oil pressure is gradually increased to test pressure in plug, directly high pressure oil is transferred at upper cylinder cover.Some hydropower station
Test pressure in brake tightness pressure test has reached 16Mpa, and so big test pressure is according to traditional test
Method easily causes upper cylinder cover and cylinder body and conjunction bolt deformation fracture or even upper cylinder cover is collapsed out, to cause major accident.
Utility model content
The utility model provides a kind of brake tightness pressure test auxiliary test unit, so that big pressure be avoided to survey
Piston is directly contacted with upper cylinder cover in examination, avoids the occurrence of conjunction bolt deformation fracture or the case where upper cylinder cover collapses out.
In order to solve the above technical problems, the technology employed by the present utility model is
A kind of brake tightness pressure test auxiliary test unit, it is characterised in that: including vertically arranged door shape
Position-limited rack and the groove profile sliding rail for being connected to position-limited rack lower part；Groove profile sliding rail offers sliding slot in the middle part of upper surface, and sliding block is assemblied in
It can slide back and forth in sliding slot and along the chute, the left and right side edge of slider top is equipped with rack gear；Motor is fixed on position-limited rack
On, the end of motor rotary shaft is connected with the rack gear meshed gears with slider top.
According to above scheme, the cross section of the sliding slot on the groove profile sliding rail is convex；The cross section of the sliding block is convex
Shape.
According to above scheme, the end of the groove profile sliding rail is equipped with limit switch；The sliding block, which is equipped with, can trigger limit
The block of switch.
Compared with prior art, the utility model has the beneficial effects that providing outside by installing position-limited rack additional for brake
Restraining force, the safety of guarantee test personnel and test specimen；Drive wheel and rack transmission that brake is moved to examination by motor
Position is tested, human input is reduced, improves test efficiency；The groove profile sliding rail and sliding block of convex can anti-limited slip block during exercise
It topples；Design limit switches can limit the horizontal displacement of sliding block in order to avoid derailing.
Detailed description of the invention
Fig. 1 is the positive structure diagram of the utility model；
Fig. 2 is the left view structural representation of the utility model；
Fig. 3 is the overlooking structure diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing, the paraphrase of each label in figure
Are as follows: 1- position-limited rack, 2- motor, 3- support of motor, 4- gear, 5- sliding block, 6- groove profile sliding rail, 7- limit switch, 8- block.
The utility model includes vertically arranged door shape position-limited rack 1, position-limited rack 1 by the Q235 steel plate production of thick 20mm and
At to provide external constraint power for brake.The bottom of the inside of position-limited rack 1 is fixedly connected with the slot being arranged afterwards horizontally forward
Type sliding rail 6, the middle part of 6 upper surface of groove profile sliding rail are equipped with the sliding slot that cross section is convex.Cross section is that the sliding block 5 of convex is assemblied in
It can slide back and forth in sliding slot and along the chute.The left and right side edge at 5 top of sliding block is equipped with rack gear.Motor 2 passes through motor
Support 3 is fixed on position-limited rack 1, and the end of the shaft of motor 2 is connected with the rack gear meshed gears 4 with 5 top of sliding block, by
Motor 2 slides back and forth with movable slider 5.
The end of groove profile sliding rail 6 is additionally provided with limit switch 7, and sliding block 5 is equipped with the block 8 that can trigger limit switch 7.Limit
Switch 7 and block 8 can monitor the displacement of sliding block 5, and sliding block 5 is avoided to skid off groove profile sliding rail 6.
The specific time implementation steps of the utility model are as follows:
Step 1: position-limited rack 1, groove profile sliding rail 6, sliding block 5, motor 2, limit switch 7 and block 8 etc. are successively assembled
It is good；
Step 2: connecting the power supply of motor 2 and limit switch 7, debugs motor 2 and limit switch 7, checks entire pass
Whether motivation structure can work normally；
Step 3: after bug check, the starting rotating forward of motor 2 removes sliding block 5, then utilizes crane by brake
It is placed on sliding block 5, then starts the reversion of motor 2 for brake and move to testing position, brake is made to be located at position-limited rack 1 just
Lower section；
Indicator bracket: being located at the top of position-limited rack 1 by step 4, is then made using the piston that high pressure oil jacks up brake
The upper end of brake is contacted with position-limited rack 1, is then gradually increased oil pressure and is observed the variation of dial gauge simultaneously；If position-limited rack 1
Deflection is larger, stops testing, and then adds after stiffening plate improves intensity for position-limited rack 1 and restarts to be tested again；
Step 5: after the test, the starting rotating forward of motor 2 removes brake to brake, then according to step 1
~step 4 carries out the tightness pressure test of next brake.
