[0062] In use, the driving assembly 2 is connected with the input shaft of the opening and closing machine through the shaft coupling, and the driving assembly 2 is driven to rotate by the hydraulic assembly 4, so as to drive the opening and closing machine. When the opening and closing machine stops running, the output shaft of the driving assembly 2 is clamped and fixed by the hydraulic assembly 4 and the brake assembly 3, so as to bear the load of the output shaft of the opening and closing machine, and thus the stable operation of the device is ensured.

[0063] When the hydraulic assembly 4 drives the driving assembly 2 to run, the hydraulic oil pump 402 delivers the hydraulic oil to the oil inlet connecting nozzle 231 through the driving oil pipe 403. The hydraulic oil enters the through hole 221 through the oil inlet connecting nozzle 231, the oil inlet communication pipe 228, the oil inlet guide pipe 224 and the oil inlet pipe 222 in turn. At this time, the hydraulic oil in the oil inlet nozzle 216 enters the plunger 212, and the pressure of the hydraulic oil in the plunger 212 increases, so that the bearing seat 210 and the plunger 212 move away from each other. The bearing seat 210 can drive the sliding block 211 to move, because one end of the sliding block 211 is attached to the inner wall of the guide groove 209, and the guide groove 209 is arranged in an arc shape, and a plurality of guide grooves 209 form a ring wave structure. Therefore, when the bearing seat 210 moves away from the plunger 212, the sliding block 211 can move along the inner wall of the guide groove 209. At this time, the bearing seat 210 rotates, and the bearing seat 210 drives the plunger 212 to move, and thus drives the oil inlet nozzle 216 to rotate, until the oil inlet nozzle 216 rotates to the next through hole 221. At this time, the hydraulic oil with high pressure in the plunger 212 can enter the oil outlet pipe 223 through the through hole 221. The hydraulic oil in the oil outlet pipe 223 flows back to the hydraulic oil pump 402 and the hydraulic oil tank 401 through the oil outlet delivery pipe 227, the oil outlet communication pipe 229, the oil outlet connecting nozzle 230 and the oil return pipe 405. A plurality of bearing seats 210 move under the action of the hydraulic oil. The bearing seat 210 rotates in the inside of the fixed frame 201. The bearing seat 210 drives the plunger 212 to move. The plunger 212 drives the transmission plate 205 to rotate through the connecting block 213 and the connecting seat 214, and thus drives the transmission shaft 206 to rotate, so as to realize the traction of the opening and closing machine.

[0064] When the motion direction of the input shaft of the switch machine is switched, the hand wheel is rotated, the hand wheel drives the rotating rod 235 to rotate, the rotating rod 235 drives a drive gear 234 to rotate, at this time, the two drive gears 234 rotate in opposite directions, at the same time, the drive gear 234 drives the transmission gear 233 below it to rotate, at this time, the adjacent two transmission gears 233 rotate in opposite directions, at this time, the motion state of the four ball valves 232 is that the motion state of the adjacent two ball valves 232 is opposite, at this time, the motion direction of the hydraulic oil in the oil inlet pipeline and the oil outlet pipeline changes, because the motion direction of the hydraulic oil changes, therefore, the motion direction of the carrier seat 210 and the plunger 212 changes, thereby the rotation direction of the transmission shaft 206 changes, and then the reverse traction of the switch machine can be realized.

[0065] When the switch machine stops running, the transmission shaft 206 can be clamped and braked by the brake assembly 3, at this time, the hydraulic oil pressure in the hydraulic rod 307 is adjusted by the hydraulic oil pump 402 and the hydraulic rod oil pipe 404, so that the hydraulic rod 307 shortens, and the hydraulic rod 307 can drive the connecting frame 305 to move, so that the connecting frame 305 rotates around the pin shaft, and the connecting frame 305 can drive one end of the connecting frame 304 to move, the connecting frame 304 drives an activity frame 302 to move, so that the two activity frames 302 move close to each other, and the activity frame 302 can drive the clamp seat 303 to move, so that the two clamp seats 303 are clamped on the outside of the transmission shaft 206, thereby the clamping and braking of the transmission shaft 206 can be realized, at the same time, when the clamp seat 303 clamps the transmission shaft 206, if the transmission shaft 206 does not stop rotating after a long time of friction between the clamp seat 303 and the transmission shaft 206, at this time, the temperature between the clamp seat 303 and the transmission shaft 206 rises after friction, the resistance value of the thermistor decreases, the magnetic force of the electromagnetic cavity 3033 increases, the control clamping column 3031 extends, and the return spring 3032 is stretched, and in the process of extension of the clamping column 3031, the clamping columns 3031 on both sides first rub and engage with the protrusion 207, and then the clamping column 3031 at the middle position further restricts the transmission shaft 206, so that the transmission shaft 206 can be quickly braked when the clamp seat 303 does not stop in time, when the transmission shaft 206 completely stops, the temperature on the clamp seat 303 decreases, at this time, the resistance value of the thermistor returns, the magnetic force in the electromagnetic cavity 3033 disappears, and then the clamping column 3031 can be reset under the action of the return spring 3032, facilitating the next work of the transmission shaft 206.

Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that the technical solutions described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalent features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
