Description

Technical Field

[0001] The present invention relates to the field of metal casting, and in particular to an automatic power connection device and method for a battery pack of an iron ladle car. Background Art

[0002] At present, under the development trend of intelligent and unmanned operation in iron and steel enterprises, most iron ladle cars in enterprises are equipped with devices such as automatic positioning devices, cover adding and removing devices, automatic hook unhooking and automatic parking devices. Currently, the devices installed on the iron ladle cars above all use additional battery packs for power supply. Due to the limited space of the iron ladle car frame, the space for installing the battery pack is limited, resulting in a small capacity of the battery pack. In the prior art, when the battery pack is charged, the operator needs to remove the battery pack from the iron ladle car frame and then put it into the battery charging cabinet for charging. This charging method requires frequent removal and placement of the battery for charging. The problems existing in this situation are as follows: ① When charging, all the electrical equipment on the iron ladle car cannot be used normally and loses various functions; ② It is easy to occur that the battery pack is not removed in time, resulting in detection errors in the intelligent transportation system and the information data not matching the actual situation; ③ Since the battery is not charged in time, the battery is in a power-off state for a long time, causing damage to the battery, increasing the production cost of the enterprise, being not conducive to the operation and use of users, and also not conducive to the development of the enterprise.

[0003] In the invention patent with the publication number of CN 113385663 B and the patent name of a self-power generation and power supply system installed on an iron ladle car, a power generation unit, a power supply unit, a controller and an electric control cabinet are disclosed; the power generation unit is installed under the iron ladle car frame; the power generation unit is provided with a driving wheel, a driving wheel auxiliary wheel, a belt, a driven wheel, a clutch and a low-speed generator, and uses the kinetic energy generated during the transportation of the iron ladle car towed by a gas locomotive to convert it into electric energy, and after converting the alternating current into direct current through the charging controller in the power supply unit, it charges the storage battery; that is, the tank car charges the storage battery during transportation, and the storage battery controls the cover adding and removing action of the iron ladle through the motor controller; since its storage battery only needs to supply the power consumption of the cover adding and removing device, charging the storage battery only during transportation can meet its power supply.

Specific embodiments

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0021] As Figure 1 and Figure 2 shown, an automatic power connection device for the battery pack of an iron water tanker is proposed in an embodiment of the present invention, which includes a generator arranged on one side of the locomotive of the iron water tanker. The diesel locomotive is also equipped with a generator as the power transmission source. The device further includes a plug assembly 1 and a socket assembly 2. The plug assembly 1 and the socket assembly 2 are respectively installed at relative positions between the locomotive and the iron water tanker or between two iron water tankers that can be coupled. The plug assembly 1 includes a linear sliding mechanism, a first insulating plate 113, and a plug power connection assembly. The first insulating plate 113 is fixedly installed at the sliding end of the linear sliding mechanism, and the plug power connection assembly is fixed on the first insulating plate 113. The socket assembly 2 includes a second insulating plate 212 and a socket power connection assembly. The second insulating plate 212 is fixedly connected to the socket power connection assembly and is arranged opposite to the plug power connection assembly. The plug power connection assembly is electrically connected to the generator or the battery pack, and the socket power connection assembly is electrically connected to the battery pack.

[0022] In order to solve the problem in the prior art that the battery needs to be frequently taken on and off the hot metal car frame for charging, a generator is configured on one side of the locomotive. Plug assemblies 1 and socket assemblies 2 are respectively installed at the relative positions on the side of the locomotive close to the hot metal car or the adjacent two hot metal cars. The plug power connection assembly is electrically connected to the generator or the battery pack, and the socket power connection assembly is electrically connected to the battery pack. The first insulating plate 113 and the plug power connection assembly are driven by a linear sliding mechanism to perform an extending action until they contact the socket power connection assembly on the opposite side, realizing the power connection between the plug assembly 1 and the socket assembly 2, so as to realize the transmission of the electricity generated by the generator to the battery pack on the hot metal car frame through the plug power connection assembly and the socket power connection assembly for power supply.

[0023] An automatic power connection device for the battery pack of a hot metal car proposed by the present invention can charge the battery pack on any hot metal car. During the charging operation, the plug power connection assembly at the rear of the locomotive can be electrically connected to the generator, and the socket power connection assembly at the front of the hot metal car to be charged can be electrically connected to the battery pack on the hot metal car to be charged. Controlling the action of the linear sliding mechanism can perform the charging. It can also charge all the battery packs of a whole train of hot metal cars. During the charging operation, the plug power connection assembly at the rear of the locomotive can be electrically connected to the generator, the front socket power connection assembly of the first hot metal car close to the locomotive can be electrically connected to the battery pack, the battery pack of the first hot metal car is simultaneously electrically connected to the plug power connection assembly at the rear of the first hot metal car, the front socket power connection assembly of the second hot metal car is electrically connected to the battery pack, and the battery pack of the second hot metal car is simultaneously electrically connected to the plug power connection assembly at the rear of the second hot metal car. Connecting in series in this way and controlling the action of each linear sliding mechanism can charge all the battery packs of a whole train of hot metal cars.

[0024] Through an automated mechanical device and a supporting control system, the present invention can control the action of the linear sliding mechanism to connect the plug assembly 1 and the socket assembly 2 for power supply to the battery pack whether during transportation or when parked, as long as the locomotive and at least one hot metal car are in a coupled and close state, so as to meet the power consumption requirements of multiple electrical devices on the hot metal car. This charging method does not require removing the battery pack from the hot metal car frame. All the electrical devices on the hot metal car can be used normally during charging, which can ensure the functionality of various devices on the hot metal car. At the same time, it reduces the labor load of the operator for frequently taking on and off the battery pack and improves work efficiency. In addition, this charging method can continuously supply power to the battery pack, and automatically stops when the battery pack is fully charged, ensuring the timeliness of battery charging, avoiding the battery damage caused by the battery being in a discharged state for a long time due to untimely charging, reducing the enterprise losses, and lowering the production cost of the enterprise.

[0025] The specifications of the components of the plug assembly 1 and the socket assembly 2 are specifically set according to the distance between the adjacent sides of the two car bodies in the coupled state. It should be noted that the specifications of the components need to ensure a certain distance between the plug power connection component and the socket power connection component after installation. This distance needs to ensure that there is no contact or impact between the plug power connection component and the socket power connection component during the coupling process of the two cars, which can avoid the problem that the plug power connection component or the socket power connection component is damaged by the great impact generated when the two cars are coupled.

[0026] As a specific embodiment of the present invention, the linear sliding mechanism includes a first base plate 11, a first outer sleeve 12, a first inner sleeve 13, a first connecting plate 14, a universal buffer mechanism, a first insulating plate 113, a plug power connection component, and a power push rod 117. The first base plate 11 is welded and fixedly installed on the side of the hot metal car. The first outer sleeve 12 is welded and fixed on the first base plate 11.

The side of the second connecting plate 213 deviating from the second inner sleeve 24 is fixedly connected to a second insulating plate 212, and the socket power connection component is fixed on the outer side of the second insulating plate 212.

[0028] As a specific embodiment of the present invention, the universal buffer mechanism includes a buffer rear plate 15, a first ear plate 16, a universal connecting frame 17, a second ear plate 111 and a buffer front plate 112, the buffer rear plate 15 is installed on the first connecting plate 14, the first ear plate 16 is connected to the middle of the front side of the buffer rear plate 15, the first ear plate 16 is connected to the second ear plate 111 through the universal connecting frame 17, the side of the second ear plate 111 deviating from the universal connecting frame 17 is fixedly connected to the middle of the buffer front plate 112, and the side of the buffer front plate 112 deviating from the second ear plate 111 is fixedly connected to the first insulating plate 113; through the universal buffering effect between the first ear plate 16, the universal connecting frame 17 and the second ear plate 111, the power connection action of the plug power connection assembly and the socket power connection assembly can better adapt to the relative position changes such as the inclination and height of the plug assembly 1 and the socket assembly 2, ensuring that the power connection action of the plug power connection assembly and the socket power connection assembly can be effectively performed regardless of whether it is in the parking state or the transportation state.

[0029] To be more specific, the first ear plate 16 and the buffer rear plate 15 are perpendicular to each other, the second ear plate 111 and the buffer front plate 112 are perpendicular to each other, and the directions of the first ear plate 16 and the second ear plate 111 are perpendicular to each other, a hinge rod 119 is passed through the through hole on the first ear plate 16, and a hinge rod 2 120 is passed through the through hole on the second ear plate 111, and the directions of the hinge rod 119 and the hinge rod 2 120 are perpendicular to each other, and clearance grooves are respectively provided at both ends of the universal connecting frame 17 corresponding to the positions of the first ear plate 16 and the second ear plate 111, and clearance holes are respectively provided at the positions of the hinge rod 119 and the hinge rod 2 120, and the two ends of the universal connecting frame 17 are respectively hinged to the first ear plate 16 and the second ear plate 111 through the hinge rod 119 and the hinge rod 2 120 to achieve a universal buffering effect.

[0030] As a preferred embodiment of the present invention, the universal buffer mechanism also includes a rear locating pin 18, a front locating pin 19 and a first spring 110. The front side of the buffer rear plate 15 is located on both sides of the first ear plate 16 and is respectively connected to at least two rear locating pins 18. The buffer front plate 112 is located on the opposite sides of the rear locating pins 18 and is respectively connected to the front locating pins 19. The first spring 110 is connected between the corresponding rear locating pins 18 and the front locating pins 19. Through the elastic action of the first spring 110, the universal buffer mechanism can play a better buffering role, enhance the stability of the power-on action, effectively increase the contact force of the copper plate, avoid poor contact problems, and can effectively adapt to the changes in the spacing between the front and rear vehicles during the running process.

[0031] As a specific embodiment of the present invention, the plug power connection assembly includes a first wiring copper sheet 114 and a first contact copper plate 115. The first wiring copper sheet 114 is fixedly connected to the outside of the first insulating plate 113, and the first contact copper plate 115 is fixedly connected to the side of the first wiring copper sheet 114 deviating from the first insulating plate 113.

[0032] As a preferred embodiment of the present invention, a guiding assembly is connected between the second outer sleeve 23 and the second connecting plate 213. The guiding assembly includes a fifth ear plate 26, a guiding rod 27 and a sixth ear plate 29.

During the process of the plug power connection assembly squeezing the socket power connection assembly, the socket power connection assembly drives the second insulating plate 212, the second connecting plate 213 and the second inner sleeve 24 to compress backward. Under the limiting action of the fifth ear plate 26 and the sixth ear plate 29, the guiding rod 27 plays a guiding role in the socket power connection assembly, preventing the direction of the socket power connection assembly from rotating, and effectively avoiding the problem of poor power connection. In one embodiment, one end of the guiding rod 27 is fixedly connected to the sixth ear plate 29 through a locking nut 28, and the other end is movably inserted into a through hole on the fifth ear plate 26.

[0033] As a specific embodiment of the present invention, the socket power connection assembly includes a second wiring copper sheet 211 and a second contact copper plate 210. The second wiring copper sheet 211 is fixedly connected to the outside of the second insulating plate 212, and the second contact copper plate 210 is fixedly connected to the side of the second wiring copper sheet 211 deviating from the second insulating plate 212.

[0034] During the dynamic walking process of the front and rear vehicles, since the relative positions between the plug assembly 1 and the socket assembly 2 are constantly changing, as a preferred embodiment of the present invention, both the first contact copper plate 115 and the second contact copper plate 210 are flat plates with a certain extended area and the peripheries of the flat plates are in a structure of inverted round corners. This structure can ensure that when the relative positions of the plug assembly 1 and the socket assembly 2 change, a certain area of the copper plate surface is in contact, thereby solving the problem of automatic power connection during the dynamic change of positions. Further preferably, when the first contact copper plate 115 and the second contact copper plate 210 are in contact, they are in a cross-shaped state. This design method can reduce the usage amount of copper plate materials while increasing the possibility of contact between the first contact copper plate 115 and the second contact copper plate 210, so as to be more helpful in dealing with the dynamic change of positions.

[0035] As a preferred embodiment of the present invention, the automatic power connection device for the ladle car battery pack of the present invention further includes a positioning identifier 3, a magnetic induction switch 4, a delay controller 5 and a control system 6. The positioning identifier 3 is installed on one side where the locomotives that can be coupled are close to the ladle car or between two ladle cars, and is used to detect the distance between the two vehicles. Specifically, the positioning identifier 3 can be a laser rangefinder. The delay controller 5 is installed on one side of the positioning identifier 3 and is electrically connected to the power push rod 117, and is used to control the action of the power push rod 117 with a time delay. The magnetic induction switch 4 is installed at the extreme positions at both ends of the main body of the power push rod 117, and is used to detect and feedback information on whether the action stroke of the power push rod 117 is in place. The positioning identifier 3, the magnetic induction switch 4, and the delay controller 5 are respectively signal-connected to the control system 6.

[0036] As a preferred embodiment of the present invention, the automatic power connection device for the ladle car battery pack of the present invention further includes an arc extinguisher, which is installed on the locomotive or the ladle car on one side of the plug assembly 1 or the socket assembly 2, and is used to prevent the generation of electric sparks when the plug assembly 1 and the socket assembly 2 are in contact.

[0037] As a preferred embodiment of the present invention, a torque sensor 7 is installed at the tail of the power push rod 117, and is used to detect the torque value during the process that the power push rod 117 drives the plug power connection assembly to extend and contact the socket power connection assembly, so as to effectively prevent damage to the plug assembly 1 or the socket assembly 2 due to excessive torque. After the first contact copper plate 115 and the second contact copper plate 210 are in contact when the plug power connection assembly extends, during the continuous compression process, when the torque sensor 7 detects that the preset torque value is reached, the power push rod 117 stops acting. Although the first contact copper plate 115 and the second contact copper plate 210 are in contact, the power push rod 117 does not necessarily reach the full stroke. Since the front and rear vehicles are kept powered on during the dynamic walking process, and the distance between the plug assembly 1 and the socket assembly 2 is constantly changing, the torque sensor 7 can be set to detect the real-time torque magnitude at intervals of a certain time. If the real-time torque is greater than or equal to the preset torque value, the power push rod 117 will not continue to perform the extension action. If the real-time torque is less than the preset torque value, the power push rod 117 will continue to perform the extension action, and this cycle of detection and extension will continue until it is fully extended in place, thus solving the problem of automatic and stable power connection during the dynamic change of the distance.

[0038] An automatic power connection method for a ladle car battery pack according to an embodiment of the present invention is as Figure 3As shown, it is realized by an automatic power connection device for the battery pack of a ladle car according to the present invention. After the locomotive is coupled with at least one ladle car, first, the positioning identifier 3 will detect that the distance between the two cars has been reduced to within the set distance range and transmit the signal to the control system 6. The control system 6 determines that the two cars are coupled and in a power-connectable state based on this signal and transmits a control signal to the delay controller 5. After a certain delay, the delay controller 5 starts to control the power push rod 117 to be energized and extend forward. The power push rod 117 drives the first connecting plate 14 together with the first insulating plate 113 and the plug power connection assembly to perform the extending action until it contacts the socket power connection assembly on the opposite side. As the power push rod 117 continues to extend forward, the plug power connection assembly further presses the socket power connection assembly and drives the second insulating plate 212, the second connecting plate 213, and the second inner sleeve 24 to compress backward by a certain distance, thereby compressing the second spring 25 and increasing the top force between the plug power connection assembly and the socket power connection assembly to achieve a fully tight contact effect. At this time, the electricity generated by the generator is transmitted to the battery pack on the ladle car frame through the plug power connection assembly and the socket power connection assembly for power supply; The torque sensor 7 detects the real-time torque magnitude at regular intervals. If the real-time torque is greater than or equal to the preset torque value, the power push rod 117 will not continue to perform the extending action; if the real-time torque is less than the preset torque value, the power push rod 117 will continue to perform the extending action, and this cycle of detection and cyclic extension will continue until it is fully extended in place; Before the two cars are separated, a power-off control instruction is issued by the control system 6. The power push rod 117 is energized and retracts backward, driving the first connecting plate 14 together with the first insulating plate 113 and the plug power connection assembly to perform the retracting action. The plug power connection assembly is separated from the socket power connection assembly, and the socket power connection assembly, the second insulating plate 212, the second connecting plate 213, and the second inner sleeve 24 are reset outward to their original positions under the action of the second spring 25 to achieve the power-off operation.
