Description
Technical field
The present invention relates to building hoist test equipment equipment technical fields, more specifically, being related to a kind of conical drum shaped gear
Type progressive safety catching device testboard.
Background technology
Building hoist is the capital equipment that people and goods are vertically transported in construction, and safety anti-falling device is building hoist
Anti-fall safety device, the safety of the anti-fall effect relation of anti-dropping safety device to people and goods, its detection work can not be ignored,
Its detection is mainly tested using testing stand method at present, principle is that motor provides dynamic torque and speed, and encoder is surveyed
Rotating speed is measured, catching device centrifuges spring by adjusting centrifugal brake block is thrown away in calibration velocity interval, clasps cone drum boss, cone
Drum rotation, copper nut rotation apply pressure to brake lining, carry out implementation braking brake, and system gives a calibration braking and turns round
Square, braking torque stop when increasing the value.Systematic survey goes out movement speed, torque and braking distance, is closed by testing three times
Lattice are just qualified.
Building hoist itself and the mass of object that it is carried are constant when falling, and give the gear of anti-dropping safety device
Torque is also constant, is found in detecting work, is different from by the test value for testing three times three times, the reason is that cone drum
Boss circumferentially throw away by 4 equal points of distributions, centrifugal brake block, and the position being buckled between boss is random, so action speed three times
Degree is different, and since the torque of motor is related with braking torque with speed, so torque three times is also different, therefore this method is surveyed
Amount, it is different from the practical torque for generation of falling of building hoist that driving device provides torque.
Invention content
The object of the present invention is to provide a kind of cone of gears drum type progressive safety catching device testboard, which is used for
Building hoist fall torque simulation, can be to avoid the error of traditional test platform, the constant torque of test, with situation of actually falling
It is consistent.
To achieve the goals above, the technical solution adopted by the present invention is as follows：
A kind of cone of gears drum type progressive safety catching device testboard, including printer, display, control system, frequency conversion
Device, encoder, speed reducer, catching device and handwheel, the control system by circuit respectively with display, printer, frequency conversion
Device is connected with encoder, and the encoder is connect by circuit with speed reducer, and the speed reducer is distinguished by transmission mechanism
Connect with catching device and handwheel, further include torque sensor, motor and hydraulic sensing brake, the motor by circuit with
Frequency converter connects, and the torque sensor is connect with motor and hydraulic sensing brake respectively by transmission mechanism, described
Torque sensor is also connect by circuit with control system.
The operation principle of the present apparatus is that speed simulates the acceleration that falls, speed by operating system by frequency converter change frequency
Degree reaches calibration value, and brake block is thrown away, is braked, and torque calibration value has system first to set in advance, by liquid braking device, liquid
Pressure sensor and torque sensor are automatically adjusted by control system, are kept constant.Speed reaches calibration value, and brake block is thrown away,
Cone drum is clasped, starts to brake, braking torque gradually increases, and when giving greatly to equal to calibration value, braking stops.
Compared with the prior art, beneficial effects of the present invention are as follows：
Testboard using the present invention, for building hoist fall torque simulation, can be to avoid the mistake of traditional test platform
Difference, the constant torque of test are consistent with situation of actually falling.
