Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle battery component replacement, and in particular relates to a battery replacement device for a mine electric monorail transport crane. Background Art

[0002] The battery replacement equipment of the mine electric monorail transport crane is to ensure that the crane can continue to supply power during long-term operation and avoid downtime caused by battery exhaustion. It usually includes components such as battery replacement system, charging station, and automatic control system. The battery of the mine electric monorail transport crane is usually removed from the bottom of the crane for replacement. The existing technology generally turns off the power supply and disconnects the battery first, opens the quick-opening protective cover of the battery box to expose the internal battery, and then unties the lugs and pins connecting the battery beam and the load-bearing trolley, slowly lowers the battery beam, disconnects the explosion-proof plug connection between the battery and the electric control box, removes the old battery pack from the battery beam, and properly places it. Then install the new battery pack on the battery beam and ensure that the connection is firm. Finally, the battery beam is connected to the load-bearing trolley through the lugs and pins, and slowly rises to the appropriate position, connects the explosion-proof plug between the battery and the electric control box, ensures a tight connection, and performs a test to complete the battery replacement process of the mine electric monorail transport crane. The entire process requires skilled operators to accurately install the battery pack into the battery beam, and then install the battery beam into the battery box at the bottom of the crane. If they cannot be placed in one go, and there is a slight misalignment between the three, the battery replacement process will have to be completed through multiple adjustments, which seriously affects work efficiency.

[0003] The existing Chinese patent document with publication number CN114132217B proposes an electric vehicle battery replacement device. Through the cooperation of a fixing device, the baffle on the movable seat can limit and fix one battery box, and the other battery box can be squeezed and fixed by opening the movable seats, thereby meeting the needs of quickly removing the old battery and quickly installing the new battery to solve the above problem. However, the battery pack is easily damaged due to position error during the lifting and squeezing limit process.

[0004] Therefore, the present invention proposes a battery replacement device for an electric monorail transport crane in a mine, so as to solve the problem in the prior art that a simple limiting and fixing structure is used to assist in the battery replacement operation, which easily causes squeezing and bumping of the battery pack due to position errors. The battery installation area, battery replacement area and unloading area are designed to use position sensors for position identification and cooperate with the battery replacement mobile components to assist in completing the replacement of the battery at the bottom of the crane. At the same time, an error locking component is installed in the battery replacement area to block and protect the bottom of the battery in case of misalignment to prevent the battery from being damaged by bumps.

The battery installation guide rails 24 are fixedly installed on the upper surface of the crane battery exchange platform 21, and the interior of the battery installation guide rails 24 are evenly provided with guide sliding wheels. An installation area positioning sensor 27 and an unloading area positioning sensor 29 are symmetrically arranged on both sides of the lower surface. The installation area positioning sensor 27 is arranged on the side close to the battery installation area limit protection frame 22, and the unloading area positioning sensor 29 is arranged on the side close to the battery unloading area limit protection frame 23. A battery swap area positioning sensor 28 is fixedly installed in the middle of the lower surface of the battery swap operating platform 2, and a battery box landing area limit grating 25 is fixedly installed in the middle of the upper surface of the battery swap operating platform 2. The battery beam lifting and adjusting frame 3 includes a sliding installation platform 31 fixedly installed on both sides of the middle of the battery swap operating platform 2, and a sliding installation platform 31 is slidably installed above the battery beam lifting and adjusting frame 3. The battery beam lifting and adjusting frame 3 is internally provided with a driving The sliding installation platform 31 slides with an adjustment transmission assembly 32, a lifting telescopic rod 33 is fixedly installed above the sliding installation platform 31, an automatic mechanical clamp assembly 34 is arranged at the upper end of the lifting telescopic rod 33, a grating baffle 341 adapted to the position of the limiting grating 25 of the battery box landing area is arranged on the inner side of the automatic mechanical clamp assembly 34, and the inner surface of the power exchange operating platform 2 is symmetrically provided with limiting slide rails adapted to the rollers on both sides of the power exchange mobile trolley 41, a rack 411 is fixedly installed on the lower surface of the power exchange mobile trolley 41, and a gear driving moving assembly 42 for driving the rack 411 to slide is arranged at the bottom of the power exchange operating platform 2, the power exchange area bearing platform 43 and the installation area bearing platform 44 are symmetrically slidably installed above the power exchange mobile trolley 41,The surface of the crane battery swap platform 21 is provided with slide grooves compatible with the battery swap area bearing platform 43 and the installation area bearing platform 44. The battery swap area bearing platform 43 has the same structure as the installation area bearing platform 44. The battery swap area positioning sensors 46 are symmetrically arranged on both sides of the battery swap area bearing platform 43, and the installation area positioning sensors 45 are symmetrically arranged on both sides of the installation area bearing platform 44. The upper surface of the battery swap mobile vehicle 41 is provided with an electromagnetic control driving lifting component 47 for driving the installation area bearing platform 44 and the battery swap area bearing platform 43 to lift. In this embodiment, the battery swap operating frame 1 is used to fix the battery swap operating table 2. Manual working standing platforms are arranged all around the battery swap operating frame 1 to facilitate manual delicate operations of battery disassembly and installation. The top of the battery platform 21 is divided into three areas: the battery installation area, the battery exchange area and the battery unloading area. The battery installation area and the battery unloading area are limited by the battery installation area limit protection frame 22 and the battery unloading area limit protection frame 23 respectively. The edge anti-static buffer strip 221 mainly wraps the upper edge of the battery to prevent bumps when the battery exchange area bearing platform 43 and the installation area bearing platform 44 are lifted to fix the battery. The buffer pad 231 mainly plays an elastic support role for the battery unloading area limit protection frame 23, and provides a certain degree of buffer protection when the battery exchange mobile cart 41 moves to transport the disassembled old battery to the battery unloading area. The battery box landing area limit grating 25 is in the middle of the battery exchange area, and the automatic mechanical clamp With the cooperation of the lifting telescopic rod 33, the component 34 extends into the battery box at the bottom of the mine electric monorail transport crane to clamp the crane battery beam 5. When the lifting lug of the crane battery beam 5 is untied, the crane battery beam 5 is slowly pulled down vertically, and the grating baffle 341 shields the grating of the battery box landing area limit grating 25. The optical signal sensor cooperates to work. When the grating baffle 341 completely blocks the grating of the battery box landing area limit grating 25, it means that the battery box 51 under the crane battery beam 5 is in the correct position of the battery replacement area. This is the first repositioning. The adjustment transmission component 32 inside the battery beam lifting adjustment frame 3 can adjust the position of the sliding mounting platform 31 by using the motor threaded rod. In cooperation with the first repositioning The battery box 51 is in the correct position for battery replacement. The position information of the installation area positioning sensor 27 can be recorded as y1, the position information of the battery replacement area positioning sensor 28 can be recorded as y2, and the position information of the unloading area positioning sensor 29 can be recorded as y3. The three represent the correct position information of the battery installation area, the battery replacement area and the battery unloading area respectively. The gear-driven moving component 42 uses the motor, chain and gear to drive the rack 411 to move so as to achieve the purpose of moving the battery replacement mobile vehicle 41 inside the battery replacement operating table 2. First, make the installation area bearing platform 44 in the battery installation area, and the battery replacement area bearing platform 43 in the battery replacement area. Place the new battery in the battery installation area and loosen the mounting screws of the old battery and the battery box 51.Ensure that the battery installation area limit protection frame 22 and the new battery are installed in place. The battery installation guide rail 24 mainly serves as a guide for the sliding installation of the battery, which is convenient for the installation and unloading of the battery. Then, the position identification is performed. The position information of the installation area positioning sensor 45 can be recorded as Y1, and the position signal of the battery exchange area positioning sensor 46 can be recorded as Y2. When the vertical coordinate positions of Y1 and y1, and Y2 and y2 coincide, it means that the positions of the installation area bearing platform 44 and the battery exchange area bearing platform 43 are correct. This is the second repositioning. At this time, the electromagnetic control drive lifting component 47 uses the principle of mutual repulsion between the electromagnets installed at the bottom of the installation area bearing platform 44 and the battery exchange area bearing platform 43 and the electromagnets on the battery exchange mobile cart 41 to lift the installation area bearing platform 44 and the battery exchange area bearing platform 43. The installation area bearing platform 44 fixes the bottom of the new battery, and the battery exchange area bearing platform 43 fixes the bottom of the old battery inside the battery box 51. Finally, the replacement The electric mobile trolley 41 moves. During the movement of the battery-changing mobile trolley 41, the old battery is taken away by the battery-changing area carrying platform 43 and moved to the battery unloading area. The new battery is taken away by the installation area carrying platform 44 and moved to the battery-changing area, and is slid and installed to the inner side of the battery box 51. When the Y1 and y2, Y2 and y3 vertical coordinate positions coincide, it means that the new battery is installed in place. This is the third repositioning. Finally, the new battery is fixed to the battery box 51, and the electromagnetic control drives the lifting component 47 to work so that the installation area carrying platform 44 and the battery-changing area carrying platform 43 cancel the bottom fixation of the battery, so that the battery is left on the crane battery-changing platform 21. At this time, the new battery is replaced, and the old battery can be directly slid out from the battery unloading area along the battery installation guide rail 24. After triple positioning and identification, the three processes of battery beam pulling down, new battery installation and old battery replacement are completed. Each position is accurately positioned and identified, and the battery replacement process is completed at one time, which improves the working efficiency of the mine electric monorail transport crane.

[0039] For example 2, please refer to Figures 1 to 18On the basis of the first embodiment, in order to prevent the bottom of the old battery from being damaged by the lifting of the battery exchange area carrying platform 43 when the battery is misplaced, the present embodiment further proposes that the error locking assembly 26 is arranged on the inner side of the limiting grating 25 of the battery box landing area, and the error locking assembly 26 includes a battery box touch plate 261 slidably mounted on the inner wall of the crane battery exchange platform 21, a spring is arranged between the upper surface of one side of the battery box touch plate 261 and the lower surface of the crane battery exchange platform 21, a square spring gasket 2612 is fixedly mounted on the top of the inner surface of the battery box touch plate 261, a push plate 2611 is fixedly mounted on the lower end of the square spring gasket 2612, and the push plate 2611 is slidably mounted inside the battery box touch plate 261, and a rotating The rotary locking column 262 is rotatably installed on the inner wall of the crane power exchange platform 21. A sliding column 2621 is slidably installed at the lower part of the rotary locking column 262. A sliding protrusion 2622 is arranged above the outer surface of the sliding column 2621. An inner spiral slideway 2623 is arranged on the inner surface of the rotary locking column 262. Both sides of the lower end of the push plate 2611 are respectively fixedly connected to the lower outer surface of the sliding column 2621. A limiting sleeve 263 is arranged on the outside of the rotary locking column 262. The upper end of the limiting sleeve 263 is fixedly connected to the lower surface of the crane power exchange platform 21. A locking protection rod 264 is fixedly installed above the outer surface of the rotary locking column 262. A hinged frame 2642 is movably installed inside the locking protection rod 264. , anti-collision pads 2641 are movably installed at the upper and lower ends of the articulated frame 2642; in the present embodiment, the error locking assembly 26 is arranged on the inner side of the limit grating 25 of the battery box landing area. When the crane battery beam 5 is not pulled down, the battery box touch plate 261 will protrude out of the plane of the crane battery exchange platform 21 under the pull of the outer spring. At this time, the push plate 2611 pulls the sliding column 2621 to be located above the inner part of the rotating locking column 262, and the sliding protrusion 2622 is located in the upper section of the inner spiral slide 2623. The locking protection rod 264 is parallel to the slide groove direction of the crane battery exchange platform 21. When the crane battery beam 5 is pulled down, the bottom of the battery box 51 squeezes the battery box touch plate 261. At this time, the push plate 2611 pulls the sliding column 2621 to slide downward. The cooperation between the sliding protrusion 2622 and the inner spiral slideway 2623 converts the sliding friction force of the push plate 2611 into a torsional force to rotate the rotary locking column 262. The locking protection rod 264 will be perpendicular to the slide groove direction of the crane battery exchange platform 21, and the bottom of the battery pack 52 inside the battery box 51 will be protected and locked to prevent the battery exchange area bearing platform 43 from lifting and causing damage to the bottom of the battery pack 52 when it is misaligned. In this embodiment, it is particularly noted that the size of the inner spiral slideway 2623 inside the rotary locking column 262 is adapted to the size of the sliding protrusion 2622, and the sliding protrusion 2622 is beveled to fit the torsional direction of the inner spiral slideway 2623. The limiting sleeve 263 mainly limits the bottom of the rotary locking column 262.The square spring gasket 2612 mainly serves to connect the battery box touch plate 261 and the square spring gasket 2612, and provides the push plate 2611 with space to be squeezed and lifted when the battery box touch plate 261 is pressed and kept stationary, thereby avoiding motion interference. At the same time, when the old battery is taken away, as the new battery moves into the battery box 51, the side of the supporting platform 44 in the installation area pushes the locking protection rod 264, so that the rotating locking column 262 maintains the same rotation state as before. At this time, the sliding column 2621 is driven to rise. At this time, the battery box touch plate 261 is pressed and kept stationary, but the square spring gasket 2612 is squeezed. In short, it plays a locking and protective role on the bottom of the old battery without causing motion interference. In this embodiment, the unlocking process of the error locking assembly 26 is that the locking protection rod 264 is perpendicular to the slide groove direction of the crane power exchange platform 21 to protect the bottom of the old battery, thereby preventing To prevent the battery swap area carrying platform 43 from being lifted and bumped, the anti-collision pad 2641 and the articulated frame 2642 further play a buffering and protective role inside the locking protection rod 264, strengthen the protection of the bottom of the battery, and reduce friction. However, once the Y2 and y2 vertical coordinate positions coincide, it means that the positions of the installation area carrying platform 44 and the battery swap area carrying platform 43 are correct. At this time, the wing plate 431 corresponds to the position of the sliding column 2621. At this time, when the battery swap area carrying platform 43 is lifted under the drive of the electromagnetic control drive lifting component 47, when unlocked, the sliding column 2621 is lifted by the wing plate 431, and the push plate 2611 pulls the sliding column 2621 back to the upper part of the inner part of the rotating locking column 262, so that the rotating locking column 262 rotates to reset and unlock. At this time, the locking protection rod 264 is parallel to the slide groove direction of the crane battery swap platform 21, canceling the locking state between the battery swap area carrying platform 43 and the bottom of the old battery.

[0040] For example 3, please refer to Figures 1 to 18On the basis of the second embodiment, in order to enable the battery swap area carrying platform 43 and the installation area carrying platform 44 to automatically fix the bottom of the battery, this embodiment further proposes that wing plates 431 are fixedly installed on both sides of the lower side of the battery swap area carrying platform 43, and a battery locking pad 432 is movably installed on the upper inner side of the battery swap area carrying platform 43, and clamping plates 4322 are hingedly installed at both ends of the battery locking pad 432, and short gears 4321 are fixedly installed on both sides of the lower surface of the battery locking pad 432. Locking buckle plates 433 are symmetrically installed on both sides of the interior for rotation. Pinions 4331 are fixedly installed on both sides of the rotating shaft of the locking buckle plate 433. The side surface of the pinion 4331 meshes with the side surface of the short gear 4321. A buffer spring 434 is fixedly installed at the lower part of the battery exchange area bearing platform 43. The upper end of the buffer spring 434 is fixedly connected to the middle part of the lower surface of the battery locking pad 432. The interior of the battery exchange area bearing platform 43 is provided with an active groove adapted to the clamping plate 4322 and the locking buckle plate 433. In this embodiment, because The installation area supporting platform 44 has the same structure as the battery exchange area supporting platform 43. Therefore, this embodiment mainly describes the battery fixing process of the battery exchange area supporting platform 43. Under normal conditions, the battery exchange area supporting platform 43 falls freely under gravity and is located below the battery. After the position is correctly identified, the battery exchange area supporting platform 43 is lifted. At this time, the battery locking pad 432 is in direct contact with the bottom of the battery. The buffer spring 434 plays a role of buffering and shock absorption, and cooperates with the buffer pad on the upper surface of the battery locking pad 432 to maximize the bottom of the battery. It plays a buffering and protective role. As the battery exchange area carrying platform 43 is lifted as a whole, the battery locking pad 432 is squeezed to make the clamping plate 4322 rotate under the limit of the inner groove, which plays a clamping and limiting role on the bottom side of the battery, making it convenient for the battery exchange area carrying platform 43 to transport the battery out. Because the battery locking pad 432 is squeezed, the short gear 4321 pushes the small gear 4331, causing the locking buckle plate 433 to flip upward and fix the upper surface of the bottom of the battery, thereby increasing the stability of the battery fixation by the battery exchange area carrying platform 43.

[0041] Example 4, please refer to Figures 1 to 18On the basis of Example 3, in order to make the wing plate 431 push the sliding column 2621 to a more accurate position, this embodiment also proposes that push columns 4311 are fixedly installed at both ends of the inner side of the upper surface of the wing plate 431, and an offset groove 4312 is opened on the upper surface of the wing plate 431, and the push column 4311 and the offset groove 4312 are located on the same straight line; in this embodiment, the wing plate 431 mainly plays the role of installing the battery exchange area positioning sensor 2 46. Only when the position of the battery exchange area bearing platform 43 is correct, the push column 4311 can be exactly at the bottom of the square spring gasket 2612, and the square spring gasket 2612 can be pushed to unlock as the battery exchange area bearing platform 43 is lifted. When the position is wrong, the bottom of the square spring gasket 2612 will only be in the offset groove 4312 area when the battery exchange area bearing platform 43 is lifted, and the square spring gasket 2612 cannot be immediately pushed to unlock, further enhancing the role of precise positioning and protection of the bottom of the battery.

[0042] For example 5, please refer to Figures 1 to 18On the basis of the fourth embodiment, this embodiment further proposes a battery replacement method for a battery replacement device of a mine electric monorail transport crane, comprising the following steps: Step 1, pull down the crane battery beam 5, and the automatic mechanical clamp assembly 34, in cooperation with the lifting telescopic rod 33, extends into the battery box at the bottom of the mine electric monorail transport crane to clamp the crane battery beam 5, and when the lifting lug of the crane battery beam 5 is untied, slowly pull the crane battery beam 5 vertically downward, and the grating baffle 341 shields the grating of the battery box landing area limit grating 25, and uses the optical signal sensor to cooperate with the work , when the grating baffle 341 completely blocks the grating of the battery box landing area limit grating 25, it means that the battery box 51 under the crane battery beam 5 is in the correct position of the battery replacement area; step two, install the new battery, make the installation area bearing platform 44 in the battery installation area, and the battery replacement area bearing platform 43 in the battery replacement area, place the new battery in the battery installation area and loosen the mounting screws between the old battery and the battery box 51, ensure that the battery installation area limit protection frame 22 and the new battery are installed in place; step three, lift and fix the battery, perform position identification, when Y1 is aligned with y1, Y2 When it coincides with the y2 vertical coordinate position, it means that the positions of the installation area bearing platform 44 and the battery exchange area bearing platform 43 are correct. The electromagnetic control drives the lifting component 47 to lift the installation area bearing platform 44 and the battery exchange area bearing platform 43. The installation area bearing platform 44 fixes the bottom of the new battery, and the battery exchange area bearing platform 43 fixes the bottom of the old battery inside the battery box 51. Step 4: Move and exchange batteries. The gear-driven moving component 42 drives the battery exchange mobile cart 41 to move. As the battery exchange mobile cart 41 moves, the old battery is brought by the battery exchange area bearing platform 43. Move to the battery unloading area, the new battery is taken away by the installation area carrying platform 44 and moved to the battery exchange area, and is slid and installed to the inner side of the battery box 51. When the vertical coordinate positions of Y1 and y2, Y2 and y3 coincide, it means that the new battery is installed in place. Fix the new battery to the battery box 51, and the electromagnetic control drives the lifting assembly 47 to make the installation area carrying platform 44 and the battery exchange area carrying platform 43 cancel the bottom fixation of the battery, so that the battery is left on the crane battery exchange platform 21. At this time, the battery exchange of the new battery is completed, and the old battery can be directly slid out from the battery unloading area along the battery installation guide rail 24.
