The principle of work of hoistable platform is:
Detent according to different size, detent is fixed in the "T"-shaped groove 12-1 on the workbench 12-3 by securing member, particular location can move along the horizontal direction of "T"-shaped groove 12-1 or perpendicular to "T"-shaped groove 12-1 direction, and its installation can be adjusted and install by " L " shape fixture 12-2; According to needed height and position in the detent practical application, control hydraulic cylinder 12-5 work, the piston rod of hydraulic cylinder 12-5 is protruded upward, stretching out of piston rod risen workbench 12-3 in short transverse, and can accurately determine height value by scale 12-11, when reaching the desired height position, hydraulic cylinder 12-5 quits work, and utilizes this moment many group bolt 12-8 to be connected fastening with sliding panel 12-9 fixed head 12-10 with bearing pin 12-7.Namely finish the rising work of the utility model hoistable platform, adopted identical method, when hydraulic cylinder 12-5 controls its piston rod and retracts, can finish the decline work of hoistable platform downwards.Easy to operate, reliable and stable.
In the utility model practical work process:
According to by the dissimilar and specification of test detent, at first operate hoistable platform 12, adjust the height of hoistable platform 12, the mounting center of control detent is high; Then according to the specified braking moment of tested detent, select high speed shaft 4 tests or slow-speed shaft 10 tests, when specified braking moment is not more than 30000Nm, the clutch coupling 3 that is positioned at reductor 7 left sides breaks away from, slow-speed shaft 10 pilot systems break away from high speed shaft 4, carry out the dynamic brake force moment test of detent this moment at high speed shaft 4 places, when specified braking moment during greater than 30000Nm, the clutch coupling 3 and reductor 7 combinations of slow-speed shaft 10 pilot systems by being positioned at reductor 7 left sides carries out the dynamic brake force moment test of detent this moment in the slow-speed shaft system.
During the dynamic brake force moment test, make inertial flywheel 6 break away from high speed shaft 4 by operating grip 13-15, the approach switch 13-16-2 in left side and operating grip 13-15 approach, and system senses static brake torque test device breaks away from, and this moment, motor 2 turned round under default parameter, after reaching the setting rotating speed, motor 2 dead electricity, the while detent is the dead electricity brake application also, and the friction disc of detent clamps the braking couple, under the effect of drag friction power, high speed shaft 4 slowly slows down and stops.By at the constantly variation of speed of difference and the numerical value of moment of inertia, control system calculates dynamic brake force moment automatically.
During the test of static brake moment, pass through shifting fork mechanism, operating grip 13-15 stirs right side approach switch 13-16-1, this moment tooth clutch and inertial flywheel 6 combinations, the effect of approach switch 13-16-1 by the right side, system senses and is in static brake moment trystate, and motor 2 can not start.By the primer fluid pressing system, control hydraulic means 13-9 supplies with hydraulic oil, makes the action of locked rotor torque proving installation, thereby finishes the test of static brake moment.
The utility model is provided with multiple electric interlock protection and mechanical interlocking protection at test unit, and the test of static brake moment and dynamic brake force moment test can not be carried out simultaneously by the approach switch electrical interlocks; High speed shaft test and slow-speed shaft test are by the clutch mechanism interlocking, and the two can only carry out a kind of test; The static brake torque test device is prepared not in place, and hydraulic system does not start, and can not test.The detent hydraulic elevating platform also has multiple mechanical interlocking and electric interlock simultaneously, and inertial flywheel also has stationary installation, makes security of system, is difficult for maloperation, protection equipment and personal safety.
Because deadman's brake is installed on the slow-speed shaft, braking procedure is large to the impact on test platform structure and basis; The brake disc diameter is large, generally between 1600～3150mm, may reach more than the 10000mm on the part specialities (such as ship lift); Braking just rotating speed is low, during normal brake application at the beginning of rotating speed approach zero, also only be 1/tens of high speed shaft rotating speed during brake hard, or less; Different from the structure of high speed shaft service brake, mounting means is also different, and both structure differences have determined that method of testing and means also are not quite similar.So, can not carry out the deadman's brake test with the testing table of high speed shaft detent, special-purpose deadman's brake pilot system must be arranged.
Deadman's brake described in the utility model, its deadman's brake claims again slow-speed shaft detent and accident brake, slow-speed shaft 10 in reductor 7 outputs is installed slow-speed shaft brake disc 11, perhaps slow-speed shaft 10 connect spool shaft or by the ring flange of reel one end detent be installed, when a certain link of the driving-chain of lifting mechanism breaks down or service brake when losing efficacy, can be in time with article that crane hangs braking with maintain, thereby effectively avoid the generation of the major accident that article fall suddenly.Avoided in the prior art braked wheel or brake disc being installed on the high speed shaft, had the defective of larger potential safety hazard, improved security.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
