Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of emergency technology for mechanical transfer equipment failure, and in particular to a failure emergency system and method for power source failure of a transfer mechanical vehicle. BACKGROUND

[0002] The transfer equipment in the mechanical field is the core device for realizing continuous and automatic conveying of materials in industrial production and logistics systems. Its technical evolution can be traced back to the early 20th century, marked by the large-scale application of conveyor belt systems, which gradually developed from simple mechanical traction structures to complex systems integrating multiple technologies. With the increasing requirements of modern manufacturing for efficiency, precision, and flexible production, transfer equipment continues to iterate in structural design, driving mode, and control technology.

[0003] In terms of structural design, transfer equipment has undergone a transformation from rigid fixed type to modular reconfigurable form. Early equipment mainly used fixed guide rails and single conveying planes, suitable for the transmission of one-way and single-specification materials; modern systems widely use assembleable frames, multi-directional shunting platforms, and multi-level stacking layouts to adapt to the dynamic adjustment needs of material flow in different working conditions. In terms of driving technology, traditional hydraulic or pneumatic driving is gradually replaced by servo motors, stepper motors, and linear driving modules, combined with reduction gears and transmission belts, chains, or gears to achieve more precise torque output and speed matching. In terms of control technology, centralized scheduling systems based on PLC (Programmable Logic Controller) and industrial computers become mainstream, coordinating the collaborative operation of multiple devices through preset programs, and integrating photoelectric sensors, encoders, and vision recognition modules to improve the response accuracy of material positioning and path switching.

[0004] When the power source of the transfer mechanical vehicle fails, the suspended material hangs in the air without other rescue equipment, and the valuable suspended material is at great risk of being damaged even by a slight bump. To ensure the safety of the transfer equipment and protect the suspended material from damage, a reliable method is needed to safely and smoothly place the suspended material on the ground.

[0005] In the existing scheme, an emergency power unit or device with large power needs to be additionally configured, which increases the cost of equipment and transportation.

The sling mechanism c comprises the sling c1 and a leveling oil cylinder c2. The sling c1 is used for grabbing, fixing and releasing the hoisted object. The leveling oil cylinder c2 is used for adjusting the horizontal posture of the sling c1 in real time.

[0052] The slewing mechanism d is used for rotating the rehandling machine on the truck left and right, and adjusting the horizontal position of the hoisted object.

[0053] The amplitude changing mechanism a is used for adjusting the elevation angle of the sling mechanism c through the extension and retraction of the amplitude changing oil cylinder a2, and changing the vertical height and horizontal distance of the hoisted object. The amplitude changing mechanism a comprises a boom a1 and the amplitude changing oil cylinder a2. The boom a1 is used for connecting the sling c1 and the vertical lifting arm b1. The amplitude changing oil cylinder a2 is used for changing the vertical height and horizontal distance of the hoisted object.

[0054] The vertical lifting mechanism b is used for adjusting the elevation angle of the vertical lifting mechanism based on the horizontal position. The vertical lifting mechanism b comprises a vertical oil cylinder and the vertical lifting arm b1. The vertical oil cylinder is used for adjusting the elevation angle of the vertical lifting mechanism b through the extension and retraction driven by pressure oil. The vertical lifting arm b1 is used for connecting the vertical oil cylinder b2 and the boom a1. The vertical oil cylinder b2 is used for changing the vertical height and horizontal amplitude of the amplitude changing mechanism a and the hoisted object.

[0055] The fault emergency system for power source failure of the rehandling machine on the truck further comprises a chassis e mechanism. The chassis e mechanism comprises a chassis e and a control module. The chassis e is used for providing support for the rehandling machine on the truck. The control module is used for providing power for the rehandling machine on the truck. Under normal circumstances, the chassis e is powered by two oil pumps directly connected with the engine. The truck takes power through a power take-off. The transfer case drives the oil pump one, the oil pump two and the oil pump three to provide power oil sources.

[0056] Specifically, when the whole vehicle action is normal.

[0057] 1. The amplitude of the lifting and hoist c1 leveling cylinder c2 retracting cooperation action.

[0058] The oil pump 2 is taken by the engine through the transfer case, when the amplitude of the lifting, the oil pump 2 pumps high pressure oil into the one-way valve 3 into the electric proportional valve with manual operation lever 6 P, one of the electric proportional valve with manual operation lever 6 proportional solenoid is powered, high pressure oil from the electric proportional valve with manual operation lever 6 P to A, and then into the balance valve 8 and balance valve 9 into the left amplitude cylinder 7 and right amplitude cylinder 10 without rod cavity, the left amplitude cylinder 7 and right amplitude cylinder 10 with rod cavity oil through the B port of the electric proportional valve with manual operation lever 6 into T port, and then into the hydraulic oil tank 1 return port, realize the amplitude of the lifting action amplitude cylinder a2 stretch out. At the same time, the amplitude of the lifting action, the oil pump 2 28 pumps high pressure oil through the one-way valve 27, and then into the electric control leveling control valve group 25, one of the electric control leveling control valve group 25 proportional solenoid is powered, high pressure oil from the electric control leveling control valve group 25 P through B into the two-way balance valve 15 B1 to B2 into the left leveling cylinder 13 and right leveling cylinder 14 with rod cavity, the left leveling cylinder 13 and right leveling cylinder 14 without rod cavity oil through the two-way balance valve 15 A2 port to A1 port, and then through the electric control leveling control valve group A to T port into the hydraulic oil tank 1 return port with oil return filter, no longer described here, realize the hoist c1 leveling cylinder c2 retracting action because in the process of amplitude of the lifting, the hoist c1 in order to maintain the level at all times, leveling cylinder c2 must retract.

[0059] 2. The amplitude of the falling and hoist c1 leveling cylinder c2 stretch out cooperation action.

[0060] The oil pump 2 is powered by the engine through the transfer case. When the boom is falling, the oil pump 2 pumps high pressure oil into the one-way valve 3, and then into the P port of the electro-hydraulic proportional directional valve 6. The proportional solenoid of the electro-hydraulic proportional directional valve 6 is energized, and the high pressure oil flows from the P port to the B port of the electro-hydraulic proportional directional valve 6, and then enters the rod cavity of the left and right luffing cylinders 7 and 10. At this time, the control oil from the MX port of the electro-hydraulic proportional directional valve 6 with a manual operating lever enters the P port to the X1 port of the electro-proportional control valve 11 with a manual operating knob, and then enters the balance valve control port, which opens the balance valve. The oil in the rodless cavity of the left and right luffing cylinders 7 and 10 flows through the balance valves 8 and 9, and then enters the A port of the electro-hydraulic proportional directional valve 6, and then enters the T port, and then enters the return port of the hydraulic tank 1, realizing the luffing down action and the retraction of the luffing cylinder a2. At the same time of the luffing down action, the oil pump 28 pumps high pressure oil, which flows through the one-way valve 27, and then enters the electro-controlled leveling control valve group 25. The proportional solenoid of the electro-controlled leveling control valve group 25 is energized, and the high pressure oil flows from the P port to the A port of the electro-controlled leveling control valve group 25, and then enters the A1 to A2 of the two-way balance valve 15, and then enters the rodless cavity of the left and right leveling cylinders 13 and 14. The oil in the rod cavity of the left and right leveling cylinders 13 and 14 flows through the B2 port to the B1 port of the two-way balance valve 15, and then flows through the B port to the T port of the electro-controlled leveling control valve group, and then enters the return port of the hydraulic tank 1 with an oil return filter, which is not described here. This realizes the extension of the leveling cylinder c2 of the spreader c1. During the luffing down process, the leveling cylinder c2 must be extended in order to keep the spreader c1 always horizontal.

[0061] 3. Left rotation. The oil pump 23 pumps high pressure oil, which flows through the one-way valve 22, and then enters the P port of the rotation buffer valve 20. At this time, the solenoid of the electro-proportional control valve 21 with a manual operating button is energized, and the control oil from the MX port of the electro-hydraulic proportional directional valve 6 with a manual operating lever enters the P port to the X1 port of the electro-proportional control valve 21 with a manual operating button, and then enters the control oil port of the rotation buffer valve 20. The control oil of this oil port pushes the valve core of the rotation buffer valve to move and change direction, and then enters the P port of the rotation buffer valve 20, and then enters the A port, and then enters the B port of the variable displacement motor 18 and 19. At the same time, the control oil of the control oil port Y of the rotation buffer valve flows out, which opens the brake of the main rotation mechanism d. At the same time, the pressure oil provided by the oil pump 28 flows through the one-way valve 27, and then enters the P port of the control valve group 24. The solenoid Y5 of the control valve group 24 is energized, and the control oil from the P port flows through the pressure reducing valve 101, and then flows through the right position of the solenoid Y5 102, and then enters the Y port, and then enters the A port of the shuttle valve 16, and then flows through the C port, which opens the brake of the auxiliary rotation mechanism d, realizing the left rotation.

[0062] 4、Right rotation, the high pressure oil of the oil pump three 23 is pumped out through the one-way valve 22, flows to the P port of the rotation buffer valve 20, at this time the other solenoid of the electric proportional control valve 21 with the manual operation button is powered, the control oil flows from the MX port of the electric hydraulic proportional reversing valve one 6 to the P port of the electric proportional control valve 21 with the manual operation button to the X2 port, and then flows into the control oil port of the rotation buffer valve 20, the control oil of the oil port pushes the valve core of the rotation buffer valve to move the reversing, flows into the P port of the rotation buffer valve 20, flows into the B port, and then flows into the A port of the variable motor one 18 and the variable motor two 19, at the same time the control oil of the control oil port Y of the rotation buffer valve flows out to open the brake of the main rotation mechanism d, at the same time the pressure oil provided by the oil pump two 28 flows into the P port of the control valve group three 24 through the one-way valve 27, the solenoid Y5 of the control valve group three 24 is powered, the control oil from the P port flows into the Y port through the right position of the electromagnetic valve Y5 102 after pressure reduction through the pressure reducing valve 101, and then flows into the A port of the shuttle valve 16 through the C port, opens the brake of the auxiliary rotation mechanism d, and realizes right rotation.

[0063] The whole vehicle is in a normal working state, the three-way ball valve 202 in the control valve group two 5 is in a horizontal state (the oil circuit A to B is conducted), and the P port oil of the electric hydraulic proportional reversing valve one 6 is disconnected through the right position of the solenoid Y3 101 in the control valve group two 5. The three-way ball valve 202 oil circuit B to C is cut off, and is separated from the oil circuit of the oil pump three 23. The shuttle valve 16, the two-way ball valve 26 and the two-way ball valve 203 are all in a cut-off state.

[0064] When the upper vehicle loses power or the transfer case cannot normally operate, the upper vehicle cannot be provided with a power oil source, the suspended object is suspended in the air, and the suspended object needs to be safely placed on the ground through manual operation. On the other hand, the suspended object is suspended in the air, and there is an obstacle below, and the suspended object cannot be directly placed on the ground by amplitude falling and cooperating with the spreader c1 to level, at this time, the suspended object needs to be placed on the ground by rotating a certain angle and then falling and cooperating with the spreader c1 to level.

[0077] At the same time of the amplitude falling action, the chassis oil pump 29 pumps out high-pressure oil flowing through the P2 to B2 port of the control valve group 4, and then through the P2 to B2 of the control valve group 5, and then through the two-way ball valve 203 to the two-way ball valve 26 to the electro-hydraulic proportional directional valve 12 with a manual operating lever, and then the operating lever of the electro-hydraulic proportional directional valve 12 with a manual operating lever is pulled, and the electro-hydraulic proportional directional valve 12 with a manual operating lever is reversed, and the high-pressure oil flows from the P port of the electro-hydraulic proportional directional valve 12 with a manual operating lever to the A1 to A2 of the double-way balance valve 15 to the rod cavity of the left leveling cylinder 13 and the right leveling cylinder 14, and the oil in the rod cavity of the left leveling cylinder 13 and the right leveling cylinder 14 flows through the B2 port to the B1 port of the double-way balance valve 15, and then flows through the B port to the T port of the electro-hydraulic proportional directional valve 12 with a manual operating lever to the hydraulic oil tank 1 return port, realizing the lifting appliance c1 leveling cylinder c2 extension action. The amplitude slowly descends and cooperates with the lifting appliance c1 leveling to place the lifted object on the ground.

[0078] The electro-proportional control valves 11 and 21 with manual operating knobs can adjust the stroke of the proportional control valve by rotating the knob into the number of turns, control the opening degree of the balance valve, and make the amplitude slowly descend, so that the amplitude descending speed is not too fast to cause stall and damage the lifted object, causing unnecessary loss or risk.

[0079] In summary, the application provides a kind of reprinted machinery upper car power source failure fault emergency system and method, is realized by manual operation to realize the leveling of lifting appliance, rotation adjustment and amplitude drop, ensure that the lifting object is safely and smoothly placed on the ground, effectively avoid equipment damage or safety accident.The horizontal posture of lifting appliance is adjusted, the position of lifting object is corrected, and the vertical height and horizontal amplitude are controlled by manually operating valve group and oil way, to ensure that the lifting object can be accurately and safely landed in emergency state.In the event of power failure, the system can monitor whether there is an obstacle under the lifting object, and adjust the angle of the lifting object by manual rotation, to ensure that the falling path of the lifting object is unobstructed, further improve the safety of emergency operation.The travel of proportional control valve is adjusted by rotating the knob, the opening of balance valve is controlled, the amplitude is slowly lowered, and the lifting object is not damaged due to oversize opening and too fast amplitude drop speed, causing unnecessary loss or risk.

[0082] When the whole vehicle action is normal, three-way ball valve one 205, three-way ball valve two 207 and three-way ball valve three 208 are in B to A conduction and B to C cut-off state.One-way valve 206 separates the high-pressure oil pumped by oil pump one from the oil way between control valve group two 5, to ensure the normal operation of amplitude and rotation and other actions.

[0083] When emergency operation of amplitude drop and lifting appliance c1 leveling is needed, three-way ball valve one 205 in control valve group two 5 is in B to C conduction and B to A cut-off state, three-way ball valve two 207 is in B to A conduction and B to C cut-off state, and three-way ball valve three 208 is in B to C conduction and B to A cut-off state.
