Summary of the invention
The purpose of this utility model is that: a kind of linear transducer array automatic turning device is provided, to solve the above problems.
The technical solution of the utility model is: a kind of linear transducer array automatic turning device, including linear transducer array, feature exist
In: linear transducer array is connected with turnover bracket, and turnover bracket is connect with turnover mechanism, and turnover bracket is fixed in orbit, institute
State linear transducer array to be mounted on probe bracket, and be arranged on the outside of working track, meet train wheel perimeter one enclose more than battle array
Column arrangement.
It is furthermore that: the turnover mechanism be mechanical turnover mechanism, including stepper motor gear reducer, shaft coupling,
Limit switch and shaft.
It is furthermore that: the stepper motor speed reducer is electrically connected with data processing and control equipment, and is arranged in-orbit
Side.
It is furthermore that: on the outside of work rail, inside is equipped with guard rail, works between rail and guard rail for the probe bracket setting
Placement sensor.
It is furthermore that: the turnover bracket is equipped with limit switch, and is connected with shaft, the shaft and shaft coupling
It is connected, the shaft coupling is connected with stepper motor speed reducer.
The different probe combination of function is arranged on the probe bracket, when having detected that vehicle passes through, sends a signal to number
According to handling and controlling equipment, when the wheel for being judged to not needing detection, data processing and control equipment issue signal control and overturn
Motor so that turnover bracket flip outward, drive linear transducer array be turned to safety and do not detect position.Rolling stock has passed through
Cheng Hou issues control signal, and control turnover bracket is inwardly overturn, and drives probe bracket to be turned to close to work rail, entrance is standby
State.
Compared with the prior art, the advantage is that:
The linear transducer array automatic turning device of the railway car wheel on-line checking of the utility model to do not need detection

Rotation mechanism is fixed on the railway roadbed on the outside of track, and turnover mechanism and data processing and control equipment, be electrically connected, realization is automatically
Turn over function, the device stability is good and good reliability, service life extend.
Detailed description of the invention
Fig. 1 is the schematic diagram of the main structure of the linear transducer array automatic turning device of the utility model.
Fig. 2 is the partial schematic diagram of the linear transducer array automatic turning device of the utility model.
In figure, 1 is stepper motor speed reducer, and 2 be shaft coupling, and 3 be limit switch, and 4 shafts, 5 be turnover bracket, and 6 are
Probe bracket, 7 be guard rail, and 8 be work rail, and 9 be turnover mechanism, and 10 be linear transducer array.
Specific embodiment
The technical solution of the utility model is described further below in conjunction with the drawings and specific embodiments:
As shown in Figure 1, a kind of schematic diagram of the main structure of linear transducer array automatic turning device, including linear transducer array 10,
It further include the turnover bracket 5 for being mounted on 10 lower section of linear transducer array, turnover bracket 5 is connect with turnover mechanism 9, and turnover bracket 5
Fixed the linear transducer array 10 is mounted on probe bracket 6 in orbit, and is arranged in 8 outside of working track, meets train vehicle
Take turns the array arrangement of the circle of perimeter one or more.
Turnover mechanism 9 is mechanical turnover mechanism, including stepper motor speed reducer 1, shaft coupling 2, limit switch 3 and shaft
4。
The stepper motor speed reducer 1 is electrically connected with data processing and control equipment, and arranges in-orbit side.
As shown in Fig. 2, the partial schematic diagram of the linear transducer array automatic turning device of the utility model, probe bracket 6 is arranged
In 8 outside of work rail, inside is equipped with guard rail 7, and work placement sensor between rail 8 and guard rail 7.
The turnover bracket 9 is equipped with limit switch 3, and is connected with shaft 4, and the shaft 4 is connected with shaft coupling 2, institute
It states shaft coupling 2 and is connected 1 with stepper motor speed reducer.Machinery overturning working principle: when speed is in defined detection range, if sentencing
It is set to the vehicle for not needing detection, data processing and control equipment issue signal and controls turnover mechanism, so that turnover bracket is overturn
The position of vehicle is not contacted to the safety for meeting railway clearance condition and, does not detect this vehicle to realize.The present embodiment uses
Mechanical turnover mechanism, mechanical turnover mechanism can be various existing mechanical overturnings, and this example uses bearing-transmission, works as iron
When road vehicles wheel is unsatisfactory for testing conditions, under the action of controlling equipment, stepper motor speed reducer energization is acted in mechanism, warp
Shaft coupling, shaft drive turnover bracket to flip outward, and turnover bracket drives the linear transducer array of carrying to be turned to limit switch triggering
Afterwards, overturning stops.After crossing vehicle, control equipment control stepper motor speed reducer reversion, turnover bracket drives the probe of carrying
Array is turned to preset position, and stepper motor speed reducer stops working, and realizes turnover bracket close to work rail, entire system
System enters standby mode.A set of or several sets work in combination simultaneously may be implemented, reach its testing goal.
The above examples only illustrate the technical idea of the present invention, and this does not limit the scope of protection of the present invention, all
According to the technical idea provided by the invention, any changes made on the basis of the technical scheme each falls within the scope of the present invention
