the worker places the wheel pair on the rail, then the linear moving devices 1 on the two sides of the rail drive the wheel pair positioning devices to move below the wheel pair, and then the moving mechanism 3 drives the opposite moving devices 5c to move towards the wheel pair from the two sides of the wheel pair;
the opposite moving device 5c drives the first positioning wheel 5a and the second positioning wheel 5b to move in opposite directions, and the four idler wheels abut against a wheel pair rotating shaft, so that the radial movement of the wheel pair in any direction from top to bottom and from left to right is limited, and the wheel pair is prevented from jumping out of a track due to vibration in the rolling advancing process;
after the wheel set is positioned, the servo motor 1c1 starts to drive the first sliding block 1b to slide on the bottom plate 1a, so as to drive the shaft positioning mechanism 5 to clamp the wheel set to move forward, when starting, the shaft positioning mechanism 5 compresses one elastic component 4b to obtain buffering, when stopping moving, the wheel set drives the shaft positioning mechanism 5 to continue moving forward, and the shaft positioning mechanism 5 compresses the other elastic component 4b to obtain buffering;
when the two first sliding blocks 1b move at different speeds, one of the first sliding blocks 1b leads or lags relative to the other first sliding block 1b, so that the sensing plate 2a2 moves into the sensing area of the sensor 2a1, the sensor 2a1 detects that the sensing plate 2a2 sends a signal to the microprocessor 2a3, the microprocessor 2a3 sends a signal to the servo motor 1c1, and the servo motor 1c1 is controlled to accelerate or decelerate, so that the two first sliding blocks 1b are aligned again;
when a serious fault occurs in the linear moving device 1, the servo motor 1c1 is driven to accelerate only by the microprocessor 2a3, and the problem cannot be solved, wherein one first sliding block 1b lags behind greatly, so that the induction plate 2a2 and the probe 2a4 sequentially pass through the induction area of the sensor 2a1, when the probe 2a4 in one row passes through the induction area of the sensor 2a1, the sensor 2a1 sends a series of high-frequency signals to the microprocessor 2a3, and the microprocessor 2a3 sends signals to the servo motor 1c1, so that the servo motors 1c1 on two sides of the wheel set stop working simultaneously, the microprocessor 2a3 also sends signals to the alarm 2a5, and the alarm 2a5 sends an alarm to remind workers of avoiding and inform engineers of avoiding and making a visit to overhaul.
The slight front-rear distance drop in the moving process of the two first sliding blocks 1b can be compensated through the buffer mechanism 4, the output lengths of the two elastic components 4b on the same side of the axis of the wheel pair can be automatically adjusted, and the precision requirement on the rack 1a2 is lowered.
The above description is only an embodiment of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
