[0002] When the whole coal train is pushed by the locomotive to the unloading point at the inlet end of the dumper body, the locomotive and the whole coal train are separated. At this time, the whole coal train is freely parked on the heavy vehicle line track (the inlet end of the dumper body). When the dumper receives the instruction to allow unloading, the heavy vehicle shunting locomotive pulls the whole coal train to run in the direction of the dumper body. When it runs to the parking limit, the two heavy vehicle boxes are uncoupled from the whole coal transport train. At the same time, the heavy vehicle shunting locomotive continues to pull the two heavy vehicles into the dumper body. After reaching the specified limit, the heavy vehicle shunting locomotive uncouples the two heavy vehicles and withdraws to the outside of the unloading area of ​​the dumper body. The dumper unloads the two heavy vehicles. After unloading, the empty carriage is pushed to the transfer platform by the shunting locomotive, and is transported from the heavy vehicle line to the empty vehicle line through the transfer platform, and then pushed to the empty vehicle line by the empty vehicle pusher.

[0018] Among them, the hydraulic station is provided with pressure oil by a plunger pump and an electric motor. A stable working pressure (13MPa) is set by the electromagnetic overflow valve, and the three-position four-way reversing valve, hydraulically controlled one-way valve and one-way throttle valve are used to control the extension (clamping) and retraction action and speed of the double-acting cylinder 8, thereby providing a reliable power source for the heavy vehicle line anti-skid protection device.

[0019] The left traveling wheel fixing device includes a double-acting oil cylinder, a lever system and a fixing system, wherein the output end of the double-acting oil cylinder is connected to one end of the lever system, and the other end of the lever system is installed with the fixing system. The fixing system is arranged on the left traveling wheel side. The double-acting oil cylinder is used to output power to clamp the fixing system arranged on the left traveling wheel side through the lever system. The fixing system is used to fix the left traveling wheel.

[0020] The input end of the double-acting oil cylinder is connected to the hydraulic station via a connecting pipe 9, and the hydraulic station is used to provide input to the double-acting oil cylinder.

[0021] The lever system includes a lever bracket 3, a fixed bracket 6, a lever bracket connecting pin 5 and a cylinder connecting pin 7, wherein the output end of the double-acting cylinder is connected to one end of the lever bracket through the cylinder connecting pin, the fixed bracket is arranged above the double-acting cylinder and is welded to the track fixed base plate, and the two ends of the fixed bracket are connected to the lever bracket through the lever bracket connecting pin, the lever bracket connecting pin serves as the fulcrum of the lever bracket, and the lever bracket moves around the lever bracket connecting pin.

[0022] The fixing system includes a wear-resistant pressure plate 1, a fixing block 2 and a fixing block connecting pin 4, wherein the fixing blocks are arranged on both sides of the left walking wheel for fixing the left walking wheel, and the wear-resistant pressure plate is installed on the side of the fixing block facing the left walking wheel to ensure that the wear-resistant plate completely tightens the wheel rims of the first group of walking wheels of the entire train of heavy vehicles, so that the entire train of heavy vehicles is firmly fixed at the receiving point of the walking track, and the side of the fixing block facing away from the left walking wheel is connected to the other end of the lever bracket through the fixing block connecting pin.

[0023] Lubricating sleeves are installed at the connecting holes of the lever bracket and the above-mentioned pin shaft, and an oil filling hole and an oil filling nozzle are made at the end of the pin shaft. Grease is injected between the pin shaft and the sleeve through the oil filling hole to ensure that the entire bracket can move flexibly and reliably.

[0024] The working process of this utility model is:

[0025] 1. When a coal train arrives, the locomotive pushes the entire train along the track to the heavy vehicle loading and unloading point at the inlet end of the dumper. After the heavy vehicle stops, the locomotive and the train are uncoupled. At this time, the first set of wheels of the first set of heavy vehicle boxes of the entire train stops at the designated position of the heavy vehicle loading and unloading point.

[0026] 2. When the heavy vehicle reaches the designated position and the anti-skid protection device hydraulic station of the dumper heavy vehicle line provides a working pressure of about 15MPa through the plunger pump, and at the same time controls the system pressure at a constant 13MPa through the electromagnetic overflow valve. Through the three-position four-way reversing valve, the hydraulically controlled one-way valve and the energy storage tank, the double-acting cylinder (UY0810R100 / 56-160 stroke 150mm clamping force is about 10000N) completes the extension and retraction (tensioning) movement, and the speed of the double-acting cylinder movement is controlled by the one-way throttle valve.

[0027] 3. The double-acting cylinder controls the tensioning action of the cylinder piston rod through the three-position four-way reversing valve of the hydraulic system, drives the lever bracket to move through the fixed bracket, and drives the fixed block through the connecting pin of the fixed block. Finally, the fixed block applies the clamping force (10000N) generated by the double-acting cylinder to both sides of the rims of the first set of running wheels of the train heavy car through the wear-resistant plate, so that the heavy cars of the entire train are firmly fixed on the running track at the loading and unloading point, ensuring that the heavy car shunting machine is accurately hooked with the heavy car box coupler, and ensuring that the entire heavy car does not slip or move and other safety hazards.

[0028] 4. After the heavy vehicle shunting locomotive is successfully hooked with the heavy vehicle coupler, the anti-skid protection device of the heavy vehicle line of the tipping machine receives the command, and the hydraulic system outputs a driving force of about 6 MPAa. (The hydraulic station receives the command, the three-position four-way reversing valve and the hydraulically controlled one-way valve are activated, so that the double-acting cylinder uses hydraulic oil to act on the piston rod to recover. The cylinder piston rod drives the lever bracket to move through the cylinder connecting pin, and drives the fixed block through the fixed block connecting pin. Finally, the fixed block and the wear-resistant plate move in the opposite direction, leaving the rim of the first set of running wheels of the empty train car and reaching a safe distance). Ensure that the anti-skid protection device of the heavy vehicle line of the tipping machine is fully opened. At this time, the heavy vehicle shunting locomotive pulls the entire train of heavy vehicles into the tipping machine body. When the third set of heavy vehicle boxes reaches the unloading point, the heavy vehicle shunting locomotive stops running and unhooks the coupler between the second and third sets of cars. At this time, the heavy vehicle shunting locomotive continues to push the two sets of heavy vehicle cars to the designated position in the tipping machine body, completing one cycle of the heavy vehicle line anti-skid protection device work process.

[0029] The hydraulic station and its internal related equipment involved in the above-mentioned utility model are all existing technologies. The utility model only uses the hydraulic station as a power supply unit and does not include an internal control method.
