Line, 9 one end of torque sensor are connected via first shaft coupling 8 with the second roll shaft 6, and 9 other end of torque sensor is via second
Axis device 10 is connected with magnetic powder brake 11, is equipped between the first roll shaft 3 and the second roll shaft 6 and lifts plate 12, lifts 12 one end of plate warp
It is connected by the first guide rail 13 with main support 1, lifts 12 other end of plate and be connected via the second guide rail 18 with main support 1, secondary support 19
It is fixed on inside main support 1, load cylinder 16, which is located at, to be lifted immediately below 12 middle position of plate and be fixed on secondary support 19, electromagnetism
Iron 15 is connected with the piston end of load cylinder 16, lifts and is equipped with first close to 13 side of the first guide rail between plate 12 and secondary support 19
Cylinder 14 is lifted, first lifts 14 cylinder body end of cylinder is connected with secondary support 19, and first lifts 14 piston end of cylinder and lift plate 12
It is connected, lifts and lift cylinder 17 equipped with second close to 18 side of the second guide rail between plate 12 and secondary support 19, second lifts cylinder
17 cylinder body ends are connected with secondary support 19, and second lifts 17 piston end of cylinder is connected with plate 12 is lifted.
As shown in Figure 1,3, snowplough torque master lifts 12 middle position of plate and is equipped with opening, which can be with
Ensure to load 16 pistons end of cylinder and electromagnet 15 and pass through.
As shown in Figure 2,3, the load cylinder 16 of snowplough torque master is twin shaft or three axis cylinders, in order to ensure electricity
Magnet 15 adsorbs normally, therefore, to assure that load 16 piston of cylinder cannot rotate during the work time；Uniaxial cylinder nothing itself
Method anti-rotation needs that guide rail is cooperated to realize this function, this can significantly increase system bulk, and then causes to lift 12 middle opening of plate
Increase, and then influences intensity；Therefore the twin shaft or three axis cylinders for selecting high integration are as load cylinder 16, to avoid above-mentioned
The generation of problem.
The magnetic loaded type torque sensing approach of snowplough torque master the following steps are included:
1) as shown in Fig. 1,4, snowplough torque master is resetted, it is ensured that first lifts cylinder 14, second lifts cylinder
17, load cylinder 16 is in retracted mode, and electromagnet 15, magnetic powder brake 11 are not powered on；
2) as shown in figure 8, snowplough to be detected is pushed to snowplough torque master, and ensure the wheel position of foetus of snowplough
Between the first roll shaft 3 and the second roll shaft 6, when being pushed into snowplough to be measured according to from the second roll shaft 6 to the side of the first roll shaft 3
To snowplough being caused to go out to avoid because of maloperation since the first roll shaft 3 is always maintained at idle running；
3) as shown in Fig. 5,7, load cylinder 16 eject, drive be fixed on load 16 pistons end of cylinder electromagnet 15 to
Upper movement simultaneously holds out against snowplough bottom end to be measured metal shell；
4) it is powered to electromagnet 15, snowplough to be measured is adsorbed on electromagnet 15 by magneticaction；
5) load cylinder 16 is shunk, and electromagnet 15 moves downward, and snowplough to be measured is tensed in the first roll shaft 3 and the second roller
On axis 6, this step completes load to snowplough to be measured, thus increase snowplough tire and the first roll shaft 3 and the second roll shaft 6 it
Between maximal friction, avoid the problem that occurring tyre slip in measurement process；
6) start snowplough to be measured, adjust throttle and speed changer to extremely operating condition to be measured；
7) 11 power supply of magnetic powder brake is connected, and incrementally increases the braking moment of magnetic powder brake 11, is turned in this step
Square sensor 9 records torque numerical value in real time；
8) after torque record, snowplough to be measured is closed, while loading the ejection of cylinder 16, electromagnet 15 and magnetic powders brake
11 power supply of device disconnects；Electromagnet power supply disconnection movement carries out after the ejection completely of load cylinder 16, so that moment be avoided to unload
Cause system shock；
9) as shown in fig. 6, load cylinder 16 retract, while first lift cylinder 16 and second lift cylinder 17 ejection, band
It is dynamic to lift the rising of plate 12, snowplough is jacked up；Gap between first roll shaft 3 and the second roll shaft 6 causes snowplough to be difficult to directly
Release, therefore after measurement, by lift plate (12) by snowplough tire jack up to the first roll shaft 3 and the second roll shaft 6
Apex height, consequently facilitating snowplough is released equipment by worker；
10) as shown in figure 4, after snowplough is pushed away detection device, first, which lifts cylinder 16 and second, lifts the receipts of cylinder 17
It returns, device reset；
11) step 2) -10 is repeated), until completing the Rotating speed measring of all snowploughs.
As shown in figure 9, for the ease of the push-in and release of snowplough to be measured, snowplough torque master can be arranged in
Floor is hereinafter, detection of the floor in 6 range inner opening of the first roll shaft 3 and the second roll shaft, for snowplough.
