[0030] like Figure 1-5 As shown, a driver controller modification structure comprises a mounting plate 1, a panel 2 is buckled on the top surface of the mounting plate 1, a speed regulating unit 3 is further arranged on the mounting plate 1, and a reversing unit 4 is arranged on the mounting plate 1, and the speed regulating unit 3 and the reversing unit 4 are mechanically interlocked, characterized in that: the speed regulating unit 3 comprises a speed regulating hand wheel 3-1 and a cam controller 10 matched with the speed regulating hand wheel 3-1, the cam controller 10 comprises a rotating shaft 11 and a cam piece 12 arranged on the rotating shaft 11, the cam piece 12 is arranged on the rotating shaft at intervals, the cam controller comprises a rotating shaft and a cam piece arranged on the rotating shaft, the cam piece is arranged on the rotating shaft at intervals, and the cam controller comprises a 0 position-start protection position 5, a 1 position-low speed operation position 6, a 3 position-protection position 7, a 4 position lowering position 8, and a 5 position-increasing speed position 9;

[0031] The cam pieces are provided with six pieces, and grooves are formed on the cam pieces, and the angles and sizes of the grooves are different.

[0032] The present invention realizes the speed regulation and steering of the driver controller through the cooperation of the speed regulation unit 3 and the reversing unit 4 (disclosed in the prior art).

[0033] To avoid the situation when the hand wheel is driven by the rotating shaft to rotate, when the contacts are opened or closed, the normal closure of the contacts cannot be guaranteed. The length of the groove at the speed regulating position on the 5th position - the increased speed position 9 corresponding to the cam piece is greater than the length of the other grooves.

[0034] The 0-position-start protection position 5, the 1-position-low speed operation position 6, the 3-position-protection position 7, the 4-position-reducing position 8, and the 5-position-increasing speed position 9 correspond to cam pieces with different corresponding slots.

[0035] One end of the speed regulating hand wheel machine 3-1 passes through the mounting plate 1 and the panel 2 and protrudes from the panel 2. The other end of the speed regulating hand wheel machine 3-1 is connected to the cam controller 10. The outer peripheral surface of the cam controller 10 along the clockwise rotation direction is connected to the quick-acting switch 3-2 to drive the quick-acting switch 3-2 to operate when rotating in the clockwise direction.

[0036] Among the 0 position - start protection position 5, 1 position - low speed operation position 6, 3 position - holding position 7, 4 position reducing position 8, and 5 position - increased speed position 9 on the cam controller 10, the 4 position reducing position 8 and the 5 position - increased speed position 9 can self-reset to the 3 position - holding position 7.

[0037] When in use, the cam quick-acting switch signal is received by a micro-integrated control system based on PLC. The mounting plate 1 is provided with a micro-integrated control system based on PLC. The micro-integrated control system based on PLC is connected to the signal output end of the quick-acting switch 3-2 through a connecting line to transmit the signal output by the quick-acting switch 3-2. The micro-integrated control system based on PLC is installed at a suitable position on the inner side of the mounting plate 1. The micro-integrated control system based on PLC can be connected to the display screen through a connecting line, and the display screen is set on the mounting plate 1.

[0038] A sensor module 13 is provided on the end surface of the cam controller 10 adjacent to the cam piece 12, and the sensor module 13 is connected to a micro integrated control system based on a PLC via a wireless method;

The position information is sent to the micro-integrated control system based on PLC through a feedback loop. The micro-integrated control system based on PLC can monitor the horizontal position of the cam controller 10 in real time and accurately control it. The sensor module 13 is used to measure the horizontal angle change of the cam piece to be detected.

[0040] A method for modifying the structure of a driver controller, specifically comprising the following steps;

[0041] Use a special wrench to loosen the locking nuts at both ends of the camshaft on the speed control handle of the driver controller;

[0042] Remove the cam pieces from the camshaft one by one, install the cam piece with the longer groove at the lifting position according to the corresponding speed adjustment position of the cam piece, swap the positions of the cam pieces, and reinstall all the cam pieces;

[0043] Finally, tighten the locking nuts at both ends and use a special wrench to adjust the cam to the required angle;

[0044] Put the driver controller in the vehicle for testing.

[0045] When the Su Sohu driver controller issues a traction or braking command, it controls the speed control hand wheel to achieve speed control, causing the control shaft to rotate and drive the speed control cam ( Figure 3 , Figure 4) rotates, replaces the adjacent cam pieces, and according to the speed regulation position corresponding to the cam piece adjacent to the lifting point, replaces the cam piece with a relatively long groove and installs it at the lifting point position to ensure the normal closure of the contacts.

[0046] The groove lengths of each cam piece are different, and the movement of the roller is accurately transmitted to the contact point by changing the position of the cam piece, so that it is closed.

[0047] A driver controller modification structure is applied to the driver controller of Dongfeng 7G locomotive and can monitor the position of the cam controller in real time and precisely control it through a micro integrated control system based on PLC.

[0048] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0049] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
