Description
Technical field
Hoisting machinery technical field is the utility model is related to, especially a kind of low speed shaft brake efficiency test static brake
Force test device.
Background technology
Low speed shaft brake refers to be arranged in the brake after transmission system reductor, is relative to high speed shaft brake
For.Turned round because the reduction of speed by slowing down increases, so transmission system rotating speed is relatively low, and the moment of torsion of transmission system is very big.Therefore,
The initial speed of braking of low speed shaft brake is low, and rotating speed at the beginning of during normal brake application is also only high speed rotating speed during brake hard close to zero
1/tens, it is or smaller；Slow-speed shaft brake braking force is larger, and generally more than 63000N, structural strength are big, volume and from
Weight is also larger, most common to be used as deadman's brake, direct brake drum flange.
Because slow-speed shaft brake initial velocity is low, some is even close to zero, so low speed shaft brake is mainly examined
Static brake power；Further, since slow-speed shaft brake braking force is big, braking work is big, if carrying out Dynamic Inertia experiment, examination
Test more dangerous, big to experimental rig destructiveness height, experiment work amount；Furthermore standard GB/T/T30221《Industry braking
Device energy efficiency test method》Also clear stipulaties, brake force can survey static brake power when being more than 63000N brake efficiency test,
Dynamic brake power is not required.Therefore, this patent specialize in one kind be suitable for low speed shaft brake test static brake power
Device.
Low speed shaft brake mainly has hydraulic caliper-disc brake, electromagnetism spot-type disc brake etc..
Test device of the prior art, to test the braking moment of high speed shaft brake, the static brake torque of test
It is smaller, generally no greater than 30000Nm.It can also be tested for the less low speed shaft brake of brake force on such device,
But slow-speed shaft brake torque is generally more than its test scope, therefore it can not typically test the static state of low speed shaft brake
Brake force.There is also following shortcoming for the device：
(1) brake disc is not suitable with all brakes.The braking width of jaw of brake varies, it is desirable to the thickness of brake disc
Degree is consistent with brake width of jaw；The diameter of brake disc is high consistent with the structure of brake and center.It is so different
Brake requires different brake discs.
(2) it is little to test brake force.Limited by structure, lever ratio, the power of test of the general device is little, static brake
The test scope of torque in 30000Nm once.
(3) take up space big.Because brake disc diameter is big, lever length, along with needed for hydraulic lever and brake installation
The space wanted so that the space that the device needs is very big.
(4) it is complicated.The apparatus structure is complicated, and parts are more, and transmission requires high, and requirement on machining accuracy is high.
(5) brake installation is inconvenient.Because brake will will be through according to theoretical friction radius, brake jaw center line
The brake disc center of circle is crossed, causes brake installation extremely complex.In most cases need individually designed frock, it is time-consuming, laborious, take
Money.
(6) precision is not high.Because installation requirement is high, friction radius, jaw center line inaccuracy easily causes measuring accuracy
It is not high.
(7) it is short to test stroke.The rotary motion of brake disc, row of hydraulic cylinder itself are changed into by the linear motion of hydraulic cylinder
Journey is just short, is converted into the rotary motion of brake disc, and the radian turned over is also short, is unfavorable for averaging.
(8) cost is high.Complicated, volume is big, it is desirable to which precision is high, and hydraulic push rod, lever are supported, brake disc supports, system
Dynamic device mounting seat etc. is required for consolidated subsoil, therefore cost is high.
(9) brake disc of multiple specifications is needed.
(10) brake disc inconvenience is changed.Slow-speed shaft brake braking force is big, and brake disc is also big, and weight is big, dismantles brake disc
It is very inconvenient.
(11) composition error is big.Test for braking moment, it is necessary to changed by theoretical friction diameter and lever ratio
It is counted as brake force.The computing of process is more, and composition error is big.

Magnetic flux crosses joystick 115 and controls turning motor 44, makes the rotary motion of crane arm 102, and brake is transported into brake installation
The correct position of slide unit 9, after revolution in place, revolution electromagnetic brake 43 brake application braking, when, turns round static, passes through joystick
115 control elevator motors, brake is set to drop on brake installation slide unit 9.
In order to avoid brake raising is too high during winding lifting and decline, encounter arm support, also avoid steel wire rope 103 from existing
Turnup on reel, therefore elevator encoder 48 is housed in motor end, to play measurement lifting altitude and position-limiting action in real time, limitation
Lifting altitude and descending depth.During revolution operation, in order to avoid angle of revolution does not get higher than safe range, in the tail of turning motor 44
Portion is equipped with rotary encoder 49, plays a part of slewing limit.
When dismantling brake, same step.Brake is sling, is turned back to the outside of slide unit 9.One can be sling again
New brake installation is tested next time.As hoisting heavy and parts when can also repair.
Above description is to explanation of the present utility model, is not the restriction to utility model, what the utility model was limited
Scope within the scope of protection of the utility model, can make any type of modification referring to claim.
