Description
Technical field
The utility model relates to building hoist test equipment equipment technical fields, more specifically, being related to a kind of gear
Bore drum type progressive safety catching device testboard.
Background technique
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,
Testing stand method is mainly used to test its detection at present, principle is that motor provides dynamic torque and speed, and encoder is surveyed
Revolving speed is measured, catching device is centrifuged 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, stopping when braking torque increases 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 be when falling it is constant, to the gear of anti-dropping safety device
Torque be also it is constant, find in detection work, be 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 movement 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 torque of the practical generation of falling of building hoist that driving device provides torque.
Utility model content
The purpose of the utility model is to provide a kind of cone of gears drum type progressive safety catching device testboard, the testboards
It falls torque simulation, and can actually fall to avoid the error of traditional test platform, the constant torque of test for building hoist
Situation is consistent.
To achieve the goals above, the technical solution adopted in the utility model 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 route respectively with display, printer, frequency conversion
Device is connected with encoder, and the encoder is connect by route 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 route with
Frequency converter connection, the torque sensor is connect with motor and hydraulic sensing brake respectively by transmission mechanism, described
Torque sensor also passes through route and connect with control system.
The working principle of the present apparatus is speed by operating system, changes frequency by frequency converter, simulates the acceleration that falls, speed
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 is gradually increased, and is given greatly to when being equal to calibration value, braking stops.
Compared with the prior art, the beneficial effects of the utility model are as follows:
Using the testboard of the utility model, fall torque simulation for building hoist, it can be to avoid traditional test platform
Error, the constant torque of test is consistent with situation of actually falling.
