Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to description literary composition
Word can be implemented according to this.
As depicted in figs. 1 and 2, the present invention provides a kind of assay device for train bogie, including: frame 1, its tool
There is the space for installing bogie and load maintainer；Four load maintainers 4, are arranged in described frame 1, to turn to described
Frame 7 imposed load；Four pressure-bearing sensors 6, each pressure-bearing sensor 6 be arranged on a load maintainer and described bogie it
Between, to detect the load that this load maintainer applies to described bogie；Controller, its communication be connected to four load maintainers and
Four pressure-bearing sensors, wherein, prestore load theoretical value in described controller, described controller is according to described pressure-bearing sensor
The load detected, controls corresponding load maintainer and adjusts the load applied to bogie, until described pressure-bearing sensor is examined
The load surveyed is consistent with load theoretical value.
The present invention is provided with a pressure-bearing sensor between load maintainer and bogie, utilizes the detection of pressure-bearing sensor to be somebody's turn to do
The load that load maintainer is applied to bogie, the load that controller is detected according to this pressure-bearing sensor, controlled loading machine
Structure adjusts the load applied to bogie, until the load detected by pressure-bearing sensor is consistent with load theoretical value, and explanation
The load that load maintainer is applied to bogie is consistent with load theoretical value.The load detected when each pressure-bearing sensor all with
When load theoretical value is consistent, then the load that four load maintainers of explanation are applied to bogie is consistent with each other, such that it is able to turning
Test to frame, and then obtain the highest result of the test.
Four load maintainers are individually regulated by the present invention, and the load making each load maintainer be applied can meet to be wanted
Asking, response time is short, and governing speed is fast, it is ensured that four load Complete Synchronizations load.
For example, load theoretical value is 18 tons, and the load detected when 3 pressure-bearing sensors is 18 tons, and is left
The load that detected of a pressure-bearing sensor be only 16 ton hours, then controller controls last load maintainer and increases load,
The load detected when last pressure-bearing sensor is also 18 tons, illustrates that the load of last load maintainer increases to properly
Amplitude, the load that now 4 load maintainers are applied is equal.
The frame 1 of the present invention includes a crossbeam 2, column 3 and a base 9, and crossbeam 2 is fixed on a column
On, and supported by a column, a column is fixed on base, and crossbeam, a column and base form an envelope
The framework closed, bogie 7 is arranged in the space 10 that this framework is surrounded, and four load maintainers 4 are fixed on this crossbeam, thus
To the bogie imposed load being positioned at below crossbeam.
In one embodiment, in the described assay device for train bogie, described load maintainer 4 is oil cylinder.
The advantage that this assay device has simple in construction.
Please see Figure 1, in one embodiment, in the described assay device for train bogie, described controller root
The load detected according to described pressure-bearing sensor, controls corresponding load maintainer and adjusts the load applied to bogie, specifically lead to
Cross procedure below to realize: described controller is connected with four oil cylinder communications by four electro liquid proportion pressure valves 11, described control
Device, according to the load detected by described pressure-bearing sensor, adjusts the oil pressure of described electro liquid proportion pressure valve, thus adjusts correspondence
The load that applies to described bogie of oil cylinder.Specifically, when needs increase load, then increased by electro liquid proportion pressure valve
Add the oil pressure to oil cylinder, otherwise, then reduce the oil pressure to oil cylinder by electro liquid proportion pressure valve.At controller to electric-hydraulic proportion pressure
When power valve is controlled, control signal is first delivered to a digital to analog converter by controller, and control signal is turned by digital to analog converter
Be changed to control control current or voltage, electro liquid proportion pressure valve according to control control current or voltage carry out action, with adjust to
The oil pressure of oil cylinder.Preferably, controller is realized by PLC.Otherwise, the signal that pressure-bearing sensor is generated is also via analog-digital converter
After changing into digital signal, enter back into controller.It addition, control parameter also by man machine interface to controller input.
In one embodiment, in the described assay device for train bogie, described controller has pre-build
Oil pressure and the functional relationship of oil cylinder institute imposed load, described controller, according to this functional relationship, adjusts described electric-hydraulic proportion pressure
The oil pressure of power valve, thus the load that the oil cylinder adjusting correspondence applies to described bogie.For example, load theoretical value 18
Ton, the load detected when a pressure-bearing sensor is 16 tons, then controller can determine 18 tons of institutes of load according to functional relationship
Corresponding oil pressure standard value, and then make the oil pressure of electro liquid proportion pressure valve increase, until it reaches above-mentioned oil pressure standard value.
In one embodiment, in the described assay device for train bogie, described load maintainer 4 pushes away for electronic
Bar.When load maintainer uses electric pushrod, then the load that controller is detected according to pressure-bearing sensor, control electric pushrod and increase
Add deduct its load applied few.Such as, load theoretical value 18 tons, the load detected when a pressure-bearing sensor is 16
Ton hour, controller directly exports control signal to electric pushrod, and the load making electric pushrod be applied increases to 18 tons.
In one embodiment, in the described assay device for train bogie, described load maintainer includes power
Output unit 8 and be arranged at the pressure head 5 of end of described power output unit, described pressure-bearing sensor 6 is arranged at the output of described power
Between end and the described pressure head 5 in portion 8.Pressure-bearing sensor is arranged between power output unit and pressure head, can accurately detect
The load that this load maintainer is applied.
Although embodiment of the present invention are disclosed as above, but it is not restricted in description and embodiment listed
Using, it can be applied to various applicable the field of the invention completely, for those skilled in the art, and can be easily
Realizing other amendment, therefore under the general concept limited without departing substantially from claim and equivalency range, the present invention does not limit
In specific details with shown here as the legend with description.
