Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of locomotive electrical appliances, and particularly relates to a reversing handle mechanism for preventing misoperation of gear positions of a driver controller. BACKGROUND

[0002] The driver controller is used on a railway electric locomotive and an internal combustion locomotive, and serves as a main order electrical appliance for controlling traction, braking and direction of the locomotive vehicle. At present, the positioning mode of the reversing handle of the driver controller is spring type. When the driver operates the reversing handle to return from the forward position (forward running) to the zero position, if the operation force of the driver is slightly large, the reversing handle is prone to directly jump over the zero position and enter the rear position (reverse running), thereby causing reverse current in the electric circuit of the locomotive and bringing great safety hazards to the operation of the locomotive. CONTENT OF THE UTILITY MODEL

The right side of the convex arc surface is sequentially provided with a round hole and a groove. The limiting lever is connected with the limiting seat through the round hole and a pin shaft. The limiting lever is provided with a stop block at one end and a lever at the other end. A spring is arranged in the groove.

Figure 3 A gear diagram of the reversing handle mechanism for preventing gear misoperation of the driver controller provided by the embodiment of the application is shown. Figure 4 An internal part schematic diagram of the reversing handle mechanism for preventing gear misoperation of the driver controller provided by the embodiment of the application is shown.Figures 1-4 As shown, the driver controller prevents the reverse handle mechanism from misoperation of gear position, and the reverse handle mechanism comprises, from top to bottom, a reverse handle 1, a limiting seat 2, a limiting lever 3 and a cover plate 6. Figure 5 A structural schematic diagram of the reverse handle 1 is provided for the embodiment of the present application, as shown in Figure 5 As shown, the side surface of the bottom cylindrical surface of the reverse handle 1 is provided with a boss 11, the shape of the first through hole 8 in the middle of the limiting seat 2 is adapted to the boss 11 of the side surface of the bottom cylindrical surface of the reverse handle 1, the boss 11 is allowed to pass through, and the boss 11 is clamped at the bottom of the limiting seat 2.

[0029] Figure 6 A structural schematic diagram of the limiting seat 2 is provided for the embodiment of the present application, as shown in Figure 7 A structural schematic diagram of the limiting lever is provided for the embodiment of the present application, and the limiting seat 2 is fixed on the driver controller, as shown in Figure 6 As shown, the bottom of the limiting seat 2 is provided with a convex arc surface 21, and the right side of the convex arc surface 21 is provided with a circular hole 12 and a groove 9, as shown in Figure 7 As shown, the main part of the limiting lever 4 is a concave arc surface 42, one end of the concave arc surface 42 is provided with a stop block 41, the other end is provided with a lever 43, the inner side close to the one end of the lever 43 is provided with a clamping position 44, the second through hole 10 on the clamping position 44 of the limiting lever 4 is connected with the circular hole 12 on the limiting seat 2 through a pin shaft, the limiting lever 4 can rotate around the pin shaft 3, the spring 5 is located in the groove 9, one end of the spring 5 abuts against the inner side wall of the groove 9, and the other end abuts against the clamping side surface of the limiting lever 4, the convex arc surface 21 on the limiting seat 2 is tightly attached to the concave arc surface 42 on the limiting lever 4, so as to limit the counterclockwise rotation and reset of the limiting lever 4 in the limiting seat, and the direction is as shown in Figure 3 As shown.

[0030] As shown, the cover plate 6 is fixedly connected with the limiting seat 2 through the screw 7, the limiting lever 4 and the spring 5 are limited in the axial direction of the limiting seat 2, and the limiting lever 4 and the spring 5 are prevented from falling.

[0031] The lever 43 is perpendicular to the projection plane of the main part of the limiting lever 4, which is beneficial to operation.

[0032] The boss 11 of the side surface of the bottom cylindrical surface of the reverse handle 1 is square, and the square is more beneficial to accurate positioning of the gear position, and the adverse phenomenon of gear sliding is not caused.

[0033]

[0034] ​When the driver operates the reversing handle 1 from the forward position to the zero position, the block 41 blocks the boss 11 on the side of the reversing handle 1, preventing the reversing handle 1 from passing the zero position. When the driver turns the reversing handle 1 from the zero position to the rear position (reverse), the spring 5 is compressed by the lever 43 being pulled counterclockwise, and the limiting lever 4 rotates around the pin shaft by a certain angle, moving the block 41 away. At this time, the reversing handle 1 is operated clockwise to enter the rear position. When the driver needs to turn the reversing handle 1 from the rear position to the zero position, the reversing handle 1 can be directly turned counterclockwise to enter the zero position, and the limiting lever 4 does not affect the counterclockwise rotation of the reversing handle.

[0035] The structure and installation of the present application are simple, and the safety accidents caused by the reversing handle jumping the zero position and directly entering the reverse position from the forward position when the driver operates the driver controller are solved.
