Lock, spring brake application.
Manipulate in the present invention and the process of test data is electrical control cubicles with Programmable Logic Controller (PLC) as core, industry control
Electrical control that machine, operating board are constituted and data acquisition processing system are completing, and are provided with monitored picture.
The specific work process of the present invention is as follows：
With regard to taking turns brake：
As shown in Figure 1, Figure 2 and Figure 3, the brake 22 of tested wheel is arranged on bogie frame 7 by taking turns brake mounting interface 21
Left end, tested wheel brake 22 install after by rated condition by it is tested wheel brake 22 close, wheel load simulation oil cylinder 9 press
Regulation pressurization produces normal thrust, and the normal thrust is acted on to crossbeam 11 by the double bracket roller 14 on coaster 13, due to crossbeam 11
Ground is acted on by support 2, therefore crossbeam 11 produces a downward reaction force and is transferred to test chassis, so as to simulate
Heavy-duty machine wheel wheel load.Wheel load simulates the pressure transducer of 9 control loop of oil cylinder and pressure transmitter (not shown) by wheel load
Simulation oil cylinder normal thrust signal is delivered in the Programmable Logic Controller (PLC) of electrical control and data acquisition processing system.Wheel load
When increasing to rated value, oil cylinder 10 is simulated by wind-force and applies horizontal thrust (simulated wind load thrust and chassis to test chassis
Horizontal force suffered by frame 7), produce and horizontal thrust adhesion resistance in opposite direction between the wheel of wheel group 6 and track 5, should
The anti-wind resistance that adhesion resistance is as produced.As track 5 is free state along horizontal thrust direction, adhesion resistance is simultaneously to rail
The equal thrust of 5 one numerical value of road, gathers the thrust in 5 free end of track by first pressure sensor 17, and this thrust is as anti-
Windage force value.Wind-force simulation oil cylinder 10 is slow to apply horizontal thrust to test chassis, when horizontal thrust overcomes tested wheel brake
During anti-wind resistance produced by 22, the horizontal thrust that wind-force simulation oil cylinder 10 applies is transferred to test chassis by horizontal push 15,
Wheel group 6 is made to start to slide on the rail 5 or rotate, when chassis shake-up displacement limits limit switch is tested, PLC makes Hydraulic Station
Motor power-off, closes valve.The horizontal thrust signal transmission collected by first pressure sensor 17 is processed to computer
And the result of the test (generating trial curve and test report) needed for exporting.
With regard to rail clamping device：
As shown in figure 4, tested rail clamping device 24 is connected with bogie frame 7 by rail clamping device mounting interface 23, by wind-force simulation oil
Cylinder 10 applies a horizontal thrust to test chassis, produces and horizontal thrust phase between the brake pad and track 5 of tested rail clamping device 24
Anti- frictional resistance, the anti-wind resistance that the frictional resistance is as produced, frictional resistance is simultaneously to the thrust that 5 one numerical value of track is equal
(track 5 is free state along thrust direction), gathers thrust magnitude in the free end of track 5 by first pressure sensor 17, should
Thrust magnitude is Radix Saposhnikoviae Resistance Value.The thrust signal collected by first pressure sensor 17 is transferred to computer and is processed simultaneously
Result of the test (generating trial curve and test report) needed for output.Exerted a force by wind-force simulation hydraulic cylinder 10 and gradually slow increasing
Plus thrust, the horizontal thrust that wind-force simulation oil cylinder 10 applies is transferred to test chassis by horizontal push 15, until test chassis exists
Stop increasing thrust when producing rotation or slide displacement on track 5.
When above-mentioned test chassis produces rotation on the rail 5 or slides, cut with scissors with Slidable pressure stand 8 in bogie frame 7
The roller 31 for meeting place is also rolled on guided in translation support 19, and the arrangement of roller 31 does not shift when ensureing that bogie frame 7 is moved
Rollover.When above-mentioned test chassis produces rotation on the rail 5 or slides simultaneously, coaster 13 is by double bracket roller 14 also in crossbeam 11
Bottom is servo-actuated, and thereby guarantees that the synchronous operation with test chassis.
With regard to top rail machine：
As shown in figure 5, will test chassis, Slidable pressure stand 8, wheel load simulation oil cylinder 9, coaster 13, double bracket roller 14
Overall structure be moved on the right side of track, by test chassis, wheel load are simulated the overall knot of oil cylinder 9, coaster 13, double bracket roller 14
Structure is moved, and is used for the installation test of tested top rail machine 26 so as to save out work space.Head track will be passed through by formula top rail machine 26
Device attachment means 25 are connected with top rail machine mounting interface 30, adjust the height that wind-force simulates oil cylinder 10, will be tested by rated condition
The brake pad top of top rail machine 26 applies horizontal thrust by thrust shaft coupling 29 to track 5 from wind-force simulation oil cylinder 10 to rail level, this
When produce between track 5 and brake pad and the contrary frictional resistance of the horizontal thrust, the frictional resistance is anti-wind resistance, second
Pressure transducer 27 gathers the thrust magnitude and is Radix Saposhnikoviae Resistance Value.The thrust signal that second pressure sensor 27 is collected is transferred to
Computer is processed and is exported required result of the test (generating trial curve and test report).Wind-force simulation oil cylinder 10 applies
Horizontal thrust is transmitted to track 5 from thrust shaft coupling 29 through thrust coupling base 28, until track 5 stops increasing when producing slide displacement
Plus thrust.
As shown in the above, the present invention can be in the crane running wheel wheel load of laboratory simulation outside work and wind
Load is acted on, and can complete various crane wind prevention braking products (wheel brake, rail clamping device, top rail machine) using same detection means
Technical performance is tested, easy to operate, data reliability, saves man power and material.
Above description is explanation of the invention, is not the restriction to inventing, and limited range of the present invention is referring to right
Require, in the case of the basic structure without prejudice to the present invention, the present invention can make any type of modification.
