Description

Technical Field

[0001] The present application relates to the technical field of mine rail hoisting equipment, and in particular to a monorail hoisting battery replacement device. Background Art

[0002] Monorail cranes are mainly used for lifting and transporting ore and equipment in mine tunnels. Compared with diesel engines, batteries not only save energy, but are also safer and more convenient to use in mine environments, so they are used to provide energy for monorail cranes. Since the batteries of monorail cranes are large and the waiting time for charging is long, the battery replacement method is generally adopted to save charging time.

[0003] When replacing the battery of a monorail crane, a lifting platform is usually used to send the operator to the battery installation location, and the connecting mechanism and the plug and socket of the electrical connection that fix the old battery to the monorail crane are removed; after the old battery is removed, the old battery is placed on the ground using a lifting platform, and the new battery is raised to the installation location, and the operator connects the connecting mechanism and the plug and socket of the electrical connection that fixes the battery to the monorail crane, thereby completing the battery replacement of the monorail crane.

[0008] By adopting the above technical scheme, when replacing the battery of the monorail crane, the monorail crane runs along the track to the charging position of the battery, and the first movable assembly and the second movable assembly are moved to the bottom of the old battery by the lifting assembly, and then the pin is moved by the second movable assembly to cancel the fixation of the fixed hook and the movable hook, so that the old battery is detached from the monorail crane, and then the height of the first movable assembly is lowered by the lifting assembly, and the old battery falls onto the first movable assembly, and the plug is detached from the socket, and then the old battery is moved away from the battery installation position of the monorail crane by the first movable assembly, and the new battery is moved to the bottom of the battery installation position of the monorail crane, and then the height of the first movable assembly and the new battery is raised by the lifting assembly, so that the plug is inserted into the socket, and the fixed hook and the movable hook are abutted, and then the pin is moved by the second movable assembly and inserted into the fixed hook, so that the new battery and the monorail crane are fixed, and the battery replacement of the monorail crane is completed.

[0009] The automatic replacement of the storage battery of the monorail crane is realized, and the operator does not need to approach the monorail crane to remove and install the storage battery, thereby avoiding safety accidents and improving the safety of the storage battery replacement operation of the monorail crane.

[0010] Optionally, the lifting assembly includes a scissors-type lifting platform, a motor, a lead screw and a nut slider; the scissors-type lifting platform is fixedly arranged at the battery charging position, and the first moving assembly is arranged on the scissors-type lifting platform; the motor is fixedly connected to the scissors-type lifting platform; the lead screw is coaxially and fixedly connected to the motor output shaft; the nut slider is sleeved on the lead screw and threadedly connected to the lead screw, the nut slider is connected to the scissors-type lifting platform, and when the nut slider slides on the lead screw, the height of the scissors-type lifting platform changes.

[0011] By adopting the above technical solution, the first moving component is placed on the scissor lift platform, the old battery is removed and placed on the first moving component, and the new battery is placed on the first moving component. When the height needs to be adjusted, the motor is started, and the motor drives the lead screw to rotate, so that the nut slider slides along the lead screw, thereby changing the height of the scissor lift platform, and the battery is lifted and lowered by the forward and reverse rotation of the motor.

[0012] Optionally, the first moving component includes an active roller, a driven roller and a conveyor belt; the active roller is located at the top of the scissors-lifting platform and is rotatably connected to the scissors-lifting platform; at least one driven roller is provided, and the driven roller is located at the top of the scissors-lifting platform and is rotatably connected to the scissors-lifting platform; the conveyor belt is wound around the active roller and the driven roller; the scissors-lifting platform is provided with a transmission component, and the transmission component is used to transmit the power of the motor to the active roller and drive the active roller to rotate; the scissors-lifting platform is provided with an adjustment component, and the adjustment component is used to adjust the working state of the transmission component.

[0013] By adopting the above technical solution, during the battery replacement process of the monorail crane, the working state of the transmission assembly is adjusted through the adjustment assembly, so that when the old battery is removed, the transmission assembly is in a working state, and the power of the motor is transmitted to the active roller, so that the first moving assembly and the lifting assembly operate together. When there is only one battery on the conveyor belt, the transmission assembly is in a disconnected state, the power of the motor cannot be transmitted to the active roller, and the lifting assembly operates independently.

[0014] The battery is moved by utilizing the power of the motor, and the working state of the transmission component is adjusted by the adjusting component, so that when the old battery is installed on the monorail crane, the lifting component operates alone, and when the old battery is removed from the monorail crane and placed on the slide in the first installation box, the lifting component and the first moving component operate together.

[0015] Optionally, the second moving component includes a first installation box, a second installation box, a magnetic block, a slide plate and a first spring; the first installation box and the second installation box are both top-opening structures, and the first installation box is used to place the old batteries, and the second installation box is used to place the new batteries, and the first installation box and the second installation box are both placed on the conveyor belt; at least one magnetic block is fixedly provided on the first installation box and the second installation box, respectively, there is an interaction force between the magnetic block and the latch, and the magnetic poles of the magnetic block on the first installation box and the magnetic block on the second installation box are opposite; two slide plates are provided, which are slidably provided in the first installation box and the second installation box respectively; at least one first spring is provided in the first installation box and the second installation box, respectively, and the first spring is fixedly provided at the bottom of the slide plate.

[0016] By adopting the above technical solution, during the disassembly of the old battery, after the first installation box is moved upward to the bottom of the old battery by the lifting assembly, when the slide plate in the first installation box abuts against the old battery, the first installation box continues to move upward by the lifting assembly, and the old battery compresses the first spring in the first installation box so that the slide plate in the first installation box slides downward relative to the first installation box, so that the magnetic block and the latch on the first installation box are at the same height, and under the action of the mutual attraction between the magnetic block and the latch on the first installation box, the latch slides out of the fixed hook, so that the fixed hook and the movable hook are unfixed.

[0017] During the installation of the new battery, the second installation box is moved to the lower part of the battery installation position of the monorail crane by the lifting assembly and the first moving assembly, and then the second installation box and the new battery are raised by the lifting assembly, the plug is first inserted into the socket, and then the fixed hook is abutted with the movable hook, and then the second installation box and the new battery are further raised by the lifting assembly, so that the magnetic block on the second installation box is at the same height as the latch, the latch is inserted into the fixed hook, and the fixed hook and the movable hook are locked and fixed, and the installation of the new battery is completed. The control of the movement of the latch is realized, thereby realizing the control of the opening and locking of the Jane's coupler.

[0018] Optionally, the transmission assembly includes a pulley, a first magnetic wheel, a belt, a second magnetic wheel and a tensioning component; the pulley is coaxially fixed on the motor output shaft; the first magnetic wheel is coaxially arranged with the active roller and is rotatably connected to the scissors-type lifting platform; the belt is wound around the pulley and the first magnetic wheel; the second magnetic wheel is coaxially connected with the active roller, and there is an interaction force between the second magnetic wheel and the first magnetic wheel; the adjustment assembly is used to adjust the distance between the first magnetic wheel and the second magnetic wheel; the tensioning component is arranged on the scissors-type lifting platform, and the tensioning component is used to keep the belt in a tensioned state at all times; a limiting assembly is arranged on the scissors-type lifting platform, and the limiting assembly is used to limit the second mounting box.

[0019] By adopting the above technical solution, during the battery replacement process of the monorail crane, the distance between the first magnetic wheel and the second magnetic wheel is adjusted by the adjustment component. When the first magnetic wheel and the second magnetic wheel are close to each other, an interaction force is generated between the first magnetic wheel and the second magnetic wheel. When the motor drives the lead screw to rotate, the pulley also rotates, and the first magnetic wheel is driven to rotate by the belt, and the first magnetic wheel drives the second magnetic wheel to rotate, so that the active roller rotates, thereby realizing the transmission of the power of the motor to the active roller and driving the active roller to rotate. In this process, the belt is always in a tensioned state through the tensioning component. During the movement of the new battery and the old battery, the new battery is limited by the limit assembly, so that when installed, the new battery is located below the installation position of the battery of the monorail crane.

[0020] Optionally, the adjustment component includes an adjusting telescopic rod, a second spring and a connecting tube; the adjusting telescopic rod is coaxially arranged with the active roller, the fixed end of the adjusting telescopic rod is fixedly connected to the active roller, and the movable end of the adjusting telescopic rod is fixedly connected to the second magnetic wheel; the movable end of the adjusting telescopic rod divides the interior of the fixed end of the adjusting telescopic rod into a first rod-containing cavity and a first rodless cavity; the second spring is fixedly arranged in the first rod-containing cavity; the connecting tube connects the interior of the first installation box, the interior of the second installation box and the first rodless cavity, and the connection points with the interior of the first installation box and the interior of the second installation box are both located at the bottom of the slide; liquid is preset in the first installation box, the interior of the second installation box, the first rodless cavity and the connecting tube at the bottom of the slide.

[0021] By adopting the above technical solution, in the initial state, the old battery is installed on the monorail crane, and only the new battery is placed in the second installation box. At this time, the adjustment telescopic rod is in a retracted state, and there is a certain distance between the second magnetic wheel and the first magnetic wheel, so that the first magnetic wheel cannot drive the second magnetic wheel to rotate. When the old battery is removed and placed on the slide in the first installation box, the liquid in the first installation box and the second installation box is affected by the gravity of the battery, and is squeezed through the connecting pipe into the first rodless cavity, so that the adjustment telescopic rod extends, driving the second magnetic wheel to move in the direction close to the first magnetic wheel, thereby realizing the adjustment of the distance between the first magnetic wheel and the second magnetic wheel.

[0022] Optionally, the tensioning component includes a tensioning wheel, a tensioning telescopic rod and a third spring; the tensioning wheel is arranged between the pulley and the first magnetic wheel, and the tensioning wheel abuts against the belt; at least one tensioning telescopic rod is provided, the fixed end of the tensioning telescopic rod is fixedly connected to the scissors lift platform, and the tensioning wheel is rotatably connected to the movable end of the tensioning telescopic rod; the movable end of the tensioning telescopic rod divides the interior of the fixed end of the tensioning telescopic rod into a second rod-containing cavity and a second rodless cavity; at least one third spring is provided, and corresponds one-to-one with the tensioning telescopic rod, the third spring is fixedly arranged in the second rod-containing cavity, and the third spring is in a compressed state.

[0023] By adopting the above technical solution, when the motor drives the lead screw to rotate, the height of the top plate of the scissors lift platform will change, thereby changing the distance between the first magnetic wheel and the pulley. By setting the third spring, the tensioning telescopic rod can be adaptively extended and retracted, thereby driving the tensioning wheel to move, so that the belt is always in a tensioned state.

[0024] Optionally, the limit assembly is provided with at least one group, and the limit assembly includes a rotating rod, a limit rod and a limit spring; the rotating rod is rotatably connected to the scissors-type lifting platform; the limit rod is fixedly connected to the scissors-type lifting platform; and both ends of the limit spring are respectively fixedly connected to the rotating rod and the limit rod.

[0025] By adopting the above technical solution, during the battery replacement process of the monorail crane, when the lifting assembly raises the height of the second installation box and the new battery, since the lifting assembly and the first moving assembly operate together, the conveyor belt is in a moving state, which will drive the second installation box to move horizontally toward the rotating rod, and the rotating rod is limited by the limiting rod so that the rotating rod cannot rotate, thereby making the rotating rod abut against the second installation box, causing the second installation box and the conveyor belt to slide relative to each other, thereby keeping the horizontal positions of the second installation box and the new battery unchanged, and the new battery is below the installation position of the monorail crane.

[0026] Optionally, a first magnetic ring is fixedly provided on the plug; a second magnetic ring is fixedly provided on the socket, and there is a mutual attraction between the second magnetic ring and the first magnetic ring; a buffer spring is provided between the socket and the monorail crane, and both ends of the buffer spring are fixedly connected to the socket and the monorail crane respectively.

[0027] By adopting the above technical solution, during the use of the monorail crane, the first magnetic ring and the second magnetic ring attract each other, so that the plug and the socket remain fixedly connected. The buffer spring provides a buffering effect for the plug and the socket, and cooperates with the first magnetic ring and the second magnetic ring to prevent vibration during the operation of the monorail crane, which causes the plug and the socket to be disconnected.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] By providing a lifting assembly, a first moving assembly and a second moving assembly, the automatic replacement of the storage battery of the monorail crane is realized, and the operator does not need to approach the monorail crane to remove and install the storage battery, thereby avoiding safety accidents and improving the safety of the battery replacement operation of the monorail crane;

[0030] By setting the transmission assembly and the adjustment assembly, the vertical and horizontal movement of the battery is realized by the motor, and the working state of the transmission assembly is adjusted by the adjustment assembly, so that when the old battery is installed on the monorail crane, the lifting assembly operates alone, and when the old battery is removed from the monorail crane and placed on the slide in the first installation box, the lifting assembly and the first moving assembly operate together;

[0031] Through the cooperation of the second moving component and the adjusting component, when the old battery falls into the first installation box, if the old battery has electrolyte loss due to long-term use, the distance between the first magnetic wheel and the second magnetic wheel is made farther through the adjusting component, and the first magnetic wheel and the second magnetic wheel do not generate interaction force, that is, the first moving component does not work, thereby reminding the operator that the old battery is damaged and the operator should take corresponding measures.

[0051] The following is combined with Figure 1-9 This application is described in further detail.

[0052] The present application embodiment discloses a monorail hanging battery replacement device. Figure 1 and Figure 2 The monorail crane battery replacement device is used to replace the battery 2 of the monorail crane 1. The monorail crane 1 is connected to a socket 11, and the battery 2 is fixedly connected to a plug 21. The plug 21 and the socket 11 are used together. When the plug 21 is inserted into the socket 11, the battery 2 is electrically connected to the monorail crane 1.

[0053] Reference Figure 1 and Figure 2The monorail crane battery replacement device includes a Zhan's coupler 3, a lifting assembly 4, a first movable assembly 5 and a second movable assembly 6. Two Zhan's couplers 3 are provided, and the Zhan's coupler 3 includes a fixed hook 31, a movable hook 32 and a latch 33. The two fixed hooks 31 are respectively located at both ends of the monorail crane 1, and the fixed hooks 31 are fixedly connected to the monorail crane 1. The two movable hooks 32 are respectively located at both ends of the battery 2, and the movable hooks 32 are fixedly connected to the battery 2. The latch 33 is slidably inserted on the fixed hook 31, and the latch 33, the movable hook 32 and the fixed hook 31 are used in combination. When the movable hook 32 and the fixed hook 31 abut against each other, and the latch 33 is inserted into the fixed hook 31, the fixed hook 31 and the movable hook 32 are fixed.

[0054] The lifting assembly 4 is arranged at the charging position of the battery 2 and is used to drive the battery 2 to lift. The first moving assembly 5 is arranged on the lifting assembly 4 and is used to move the battery 2. The second moving assembly 6 is arranged on the first moving assembly 5 and is used to move the latch 33.

[0055] During the use of the monorail crane 1, the pin 33 is inserted into the fixed hook 31, so that the fixed hook 31 is fixed to the movable hook 32, so that the battery 2 is fixedly connected to the monorail crane 1, and the plug 21 is inserted into the socket 11, so that the battery 2 is electrically connected to the monorail crane 1, and the battery 2 provides power for the monorail crane 1. A new battery 2 is arranged on the first moving component 5.

[0056] When the power stored in the old battery 2 is exhausted and needs to be replaced, the monorail crane 1 runs along the track to the charging position of the battery 2, and the first movable assembly 5 and the second movable assembly 6 are moved to the bottom of the old battery 2 through the lifting assembly 4, and the latch 33 is moved by the second movable assembly 6 to slide out of the fixed hook 31, so that the fixed hook 31 and the movable hook 32 are unfixed, so that the old battery 2 is detached from the monorail crane 1, and then the height of the first movable assembly 5 is lowered by the lifting assembly 4, and the old battery 2 falls onto the first movable assembly 5 under the action of its own gravity, and the plug 21 is detached from the socket 11, and then the first movable assembly 5 is used to release the plug 21. The component 5 moves the old battery 2 away from the battery 2 installation position of the monorail crane 1, and moves the new battery 2 to the bottom of the battery 2 installation position of the monorail crane 1, and then the first moving component 5 and the new battery 2 are raised by the lifting component 4, so that the plug 21 is inserted into the socket 11, and the fixed hook 31 and the movable hook 32 are abutted, and then the second moving component 6 moves the pin 33 and inserts it into the fixed hook 31, so that the new battery 2 and the monorail crane 1 are fixed, and the battery 2 of the monorail crane 1 is replaced, and then the first moving component 5 and the old battery 2 are lowered by the lifting component 4.

[0057] Reference Figures 3 to 5A first magnetic ring 111 is fixedly disposed on the plug 21. A second magnetic ring 211 is fixedly disposed on the socket 11, and there is mutual attraction between the second magnetic ring 211 and the first magnetic ring 111. A buffer spring 12 is disposed between the socket 11 and the monorail crane 1, and both ends of the buffer spring 12 are fixedly connected to the socket 11 and the monorail crane 1, respectively.

[0058] During the use of the monorail crane 1, the first magnetic ring 111 and the second magnetic ring 211 attract each other, so that the plug 21 and the socket 11 remain fixedly connected. The buffer spring 12 provides a buffering effect for the plug 21 and the socket 11, and cooperates with the first magnetic ring 111 and the second magnetic ring 211 to prevent vibration during the operation of the monorail crane 1, which may cause the plug 21 and the socket 11 to be disconnected.

[0059] Reference Figure 1 and Figure 6 The lifting assembly 4 includes a scissor lift 41, a motor 42, a lead screw 43 and a nut slider 44. The scissor lift 41 is horizontally fixed at the charging position of the battery 2, and the first moving assembly 5 is arranged on the top plate of the scissor lift 41. The motor 42 is fixedly connected to the bottom plate of the scissor lift 41. One end of the lead screw 43 is coaxially fixedly connected to the motor 42, and the other end is rotatably connected to the bottom plate of the scissor lift 41. The nut slider 44 is sleeved on the lead screw 43 and is threadedly connected to the lead screw 43. The nut slider 44 is fixedly connected to the movable hinge rod of the scissor lift 41. When the nut slider 44 slides, the height of the top plate of the scissor lift 41 changes.

[0060] During the replacement of the battery 2 of the monorail crane 1, when the battery 2 and the first movable assembly 5 need to be raised or lowered, the motor 42 is started, and the motor 42 drives the screw 43 to rotate, so that the nut slider 44 slides along the screw 43, thereby changing the height of the top plate of the scissors lift 41. By adjusting the forward and reverse rotation of the motor 42, the top plate of the scissors lift 41 can be raised and lowered, thereby driving the first movable assembly 5 and the battery 2 to rise and fall.

[0061] Reference Figure 1 and Figure 3 The first moving assembly 5 includes an active roller 51, a driven roller 52 and a conveyor belt 53. The active roller 51 is located above the top plate of the scissor lift 41 and is rotatably connected to the top plate of the scissor lift 41. The axis of the active roller 51 is arranged parallel to the axis of the output shaft of the motor 42. Two driven rollers 52 are provided. The driven rollers 52 are located above the top plate of the scissor lift 41 and are rotatably connected to the top plate of the scissor lift 41. The axis of the driven roller 52 is arranged parallel to the axis of the active roller 51. The conveyor belt 53 is wound around the active roller 51 and the driven roller 52.

[0062] Reference Figure 1The scissor lift platform 41 is provided with a transmission assembly 7, which includes a pulley 71, a first magnetic wheel 72, a belt 73, a second magnetic wheel 74 and a tensioning member 75. Figure 3 The pulley 71 is coaxially arranged between the motor 42 and the lead screw 43, and the pulley 71 is fixedly connected to the output shaft of the motor 42. Figure 6 and Figure 7 The first magnetic wheel 72 is coaxially arranged with the active roller 51 and is rotatably connected with the scissor lift 41. Figure 1 A through slot is vertically arranged on the top plate of the scissor lift platform 41, and the belt 73 passes through the through slot and is wound around the first magnetic wheel 72 and the pulley 71. Figure 6 and Figure 8 The second magnetic wheel 74 is coaxially connected to the active roller 51 , and there is an interaction force between the second magnetic wheel 74 and the first magnetic wheel 72 .

[0063] Reference Figure 1 and Figure 3 The tensioning member 75 includes a tensioning wheel 751, a tensioning telescopic rod 752 and a third spring 753. The tensioning wheel 751 is disposed between the pulley 71 and the first magnetic wheel 72, the axis direction of the tensioning wheel 751 is parallel to the axis direction of the pulley 71, and the tensioning wheel 751 abuts against the belt 73. Fig. 9 Two tensioning and telescopic rods 752 are arranged in parallel and are respectively located at the two ends of the axis direction of the tensioning wheel 751. The fixed end of the tensioning and telescopic rod 752 is fixedly connected to the bottom plate of the scissor lift 41, and the tensioning wheel 751 is rotatably connected to the movable end of the tensioning and telescopic rod 752. The movable end of the tensioning and telescopic rod 752 divides the interior of the fixed end of the tensioning and telescopic rod 752 into a second rod cavity 7521 and a second rodless cavity 7522. The second rod cavity 7521 is located between the second rodless cavity 7522 and the tensioning wheel 751. Two third springs 753 are arranged. The third springs 753 correspond to the tensioning and telescopic rods 752 one by one. The third spring 753 is located in the second rod cavity 7521, and the two ends are respectively fixedly connected to the fixed end of the tensioning and telescopic rod 752 and the movable end of the tensioning and telescopic rod 752. The third spring 753 is always in a compressed state.

[0064] During the replacement of the battery 2 of the monorail crane 1, when the battery 2 needs to be moved, there is an interaction force between the first magnetic wheel 72 and the second magnetic wheel 74. When the motor 42 drives the screw 43 to rotate, the pulley 71 also rotates, thereby driving the first magnetic wheel 72 to rotate through the belt 73, and the first magnetic wheel 72 drives the second magnetic wheel 74 to rotate, so that the active roller 51 rotates, and the driven roller 52 rotates under the drive of the active roller 51, and the conveyor belt 53 rotates around the active roller 51 and the driven roller 52, thereby driving the battery 2 to move.

[0065] When the motor 42 drives the lead screw 43 to rotate, the height of the top plate of the scissors-type lifting platform 41 will change. Since the first magnetic wheel 72 is rotatably connected to the top plate of the scissors-type lifting platform 41, the distance between the first magnetic wheel 72 and the pulley 71 will change. Under the action of the third spring 753, the tensioning telescopic rod 752 adaptively retracts and retracts, and the tensioning wheel 751 moves, so that the belt 73 is always in a tensioned state.

[0066] Reference Figure 4 and Figure 6 The scissor lift 41 is provided with a second moving assembly 6, which includes a first installation box 61, a second installation box 62, a magnetic block 63, a slide plate 64 and a first spring 65. The first installation box 61 and the second installation box 62 are both fixedly arranged on the conveyor belt 53, and both are top-opening structures. The first installation box 61 is used to place old batteries 2, and the second installation box 62 is used to place new batteries 2. Two magnetic blocks 63 are fixedly arranged on the first installation box 61, and are respectively located on both sides of the first installation box 61. Two magnetic blocks 63 are fixedly arranged on the second installation box 62, and are respectively located on both sides of the second installation box 62. The magnetic poles of the magnetic blocks 63 on the first installation box 61 and the second installation box 62 are opposite. There is a mutual attraction between the magnetic block 63 on the first installation box 61 and the latch 33, and there is a mutual repulsion between the magnetic block 63 on the second installation box 62 and the latch 33.

[0067] Two slide plates 64 are horizontally arranged and are located in the first installation box 61 and the second installation box 62 respectively. The slide plate 64 in the first installation box 61 is slidably connected to the first installation box 61, and the slide plate 64 in the second installation box 62 is slidably connected to the second installation box 62. The new battery 2 is placed in the second installation box 62 and is located above the slide plate 64 in the second installation box 62. At least one first spring 65 is vertically arranged in the first installation box 61 and the second installation box 62 respectively. The two ends of the first spring 65 in the first installation box 61 are fixedly connected to the first installation box 61 and the slide plate 64 in the first installation box 61 respectively, and the two ends of the first spring 65 in the second installation box 62 are fixedly connected to the second installation box 62 and the slide plate 64 in the second installation box 62 respectively.

[0068] Reference Figure 6 and Figure 8The scissor lift 41 is provided with an adjustment assembly 8, which includes an adjustment telescopic rod 81, a second spring 82 and a connecting pipe 83. The adjustment telescopic rod 81 is located between the second magnetic wheel 74 and the active roller 51, and the axis direction of the adjustment telescopic rod 81 is coaxially arranged with the axis of the active roller 51. The fixed end of the adjustment telescopic rod 81 is fixedly connected to the active roller 51, and the movable end of the adjustment telescopic rod 81 is fixedly connected to the second magnetic wheel 74. The movable end of the adjustment telescopic rod 81 divides the interior of the fixed end of the adjustment telescopic rod 81 into a first rod cavity 811 and a first rodless cavity 812, and the first rodless cavity 812 is located between the first rod cavity 811 and the active roller 51.

[0069] The second spring 82 is located in the first rod cavity 811, and the second spring 82 has the same length direction as the adjustable telescopic rod 81. The two ends of the second spring 82 are respectively fixedly connected to the movable end of the adjustable telescopic rod 81 and the fixed end of the adjustable telescopic rod 81. The connecting pipe 83 connects the inside of the first installation box 61, the inside of the second installation box 62 and the first rodless cavity 812, and the connection points with the inside of the first installation box 61 and the inside of the second installation box 62 are both located at the bottom of the slide 64. Liquid is preset in the first installation box 61, the second installation box 62, the first rodless cavity 812 and the connecting pipe 83 at the bottom of the slide 64.

[0070] In the initial state, the old battery 2 is installed on the monorail crane 1, and only the new battery 2 is placed in the second installation box 62. At this time, the telescopic rod 81 is adjusted to be in a retracted state, and there is a certain distance between the second magnetic wheel 74 and the first magnetic wheel 72, so that the first magnetic wheel 72 cannot drive the second magnetic wheel 74 to rotate, that is, the lifting assembly 4 operates alone. During the replacement process of the battery 2 of the monorail crane 1, when the old battery 2 is removed from the monorail crane 1 and placed on the slide 64 in the first installation box 61, under the gravity of the new battery 2, the slide 64 in the first installation box 61 slides downward, so that the liquid in the first installation box 61 is squeezed through the connecting pipe 83 into the first rodless cavity 812. At the same time, under the gravity of the old battery 2, the slide 64 in the second installation box 62 slides downward, so that the liquid in the second installation box 62 is squeezed through the connecting pipe 83 into the first rodless cavity 812, thereby extending the adjustment telescopic rod 81, driving the second magnetic wheel 74 to move in the direction close to the first magnetic wheel 72, so that the second magnetic wheel 74 and the first magnetic wheel 72 can interact with each other, and when the motor 42 drives the screw 43 to rotate, the power of the motor 42 is transmitted to the active roller 51 through the transmission assembly 7, so that the lifting assembly 4 and the first moving assembly 5 operate together.

[0071] Reference Figure 1 and Figure 2Two sets of limit assemblies 9 are provided on the scissor lift 41, and are respectively located on both sides of the conveyor belt 53. The limit assemblies 9 include a rotating rod 91, a limit rod 92 and a limit spring 93. The rotating rod 91 is vertically arranged and rotatably connected to the top plate of the scissor lift 41, and the rotation axis is vertically arranged. The limit rod 92 is vertically arranged and fixedly connected to the top plate of the scissor lift 41. In the initial state, the limit rod 92 is located between the first installation box 61 and the second installation box 62. The two ends of the limit spring 93 are respectively fixedly connected to the rotating rod 91 and the limit rod 92.

[0072] During the replacement of the storage battery 2 of the monorail crane 1, after the monorail crane 1 runs along the track to the charging position of the storage battery 2, the old storage battery 2 is still installed on the monorail crane 1, so the lifting assembly 4 operates alone, and the first installation box 61 is moved upward to the bottom of the old storage battery 2 through the lifting assembly 4. When the slide plate 64 in the first installation box 61 abuts against the old storage battery 2, the first installation box 61 is moved upward by the lifting assembly 4, and the old storage battery 2 compresses the first spring 65 in the first installation box 61 so that the first storage battery 2 is charged. The slide plate 64 in the first installation box 61 slides downward relative to the first installation box 61, so that the magnetic block 63 and the latch 33 on the first installation box 61 are at the same height. Under the mutual attraction between the magnetic block 63 and the latch 33 on the first installation box 61, the latch 33 slides out from the fixed hook 31, so that the fixed hook 31 and the movable hook 32 are unfixed. Under the action of its own gravity, the old battery 2 falls onto the slide plate 64 in the first installation box 61, and the plug 21 slides downward away from the socket 11, completing the removal of the old battery 2.

[0073] When the old battery 2 is removed, the old battery 2 is located in the first installation box 61, and the new battery 2 is located in the second installation box 62. Therefore, the lifting assembly 4 and the first moving assembly 5 operate together to lower the height of the conveyor belt 53 while moving the first installation box 61 and the second installation box 62 in the horizontal direction. When the second installation box 62 abuts against the rotating rod 91 during the movement, the rotating rod 91 is pushed to stretch the limit spring 93 to rotate. When the second installation box 62 moves to the lower part of the battery 2 installation position of the monorail crane 1, the rotating rod 91 rotates and recovers under the action of the limit spring 93.

[0074] When the second installation box 62 moves to below the installation position of the battery 2 of the monorail crane 1, the second installation box 62 and the new battery 2 are raised by the lifting assembly 4. During the rising process, the plug 21 is first inserted into the socket 11 to electrically connect the new battery 2 to the monorail crane 1, and then the fixed hook 31 abuts against the movable hook 32. At this time, the second installation box 62 and the new battery 2 continue to rise by the lifting assembly 4, so that the magnetic block 63 and the latch 33 on the second installation box 62 are at the same height. Under the action of the mutual repulsive force between the magnetic block 63 and the latch 33 on the second installation box 62, when the latch 33 is inserted into the fixed hook 31, the fixed hook 31 is fixed to the movable hook 32, so that the new battery 2 is fixed to the monorail crane 1, completing the installation of the new battery 2. Finally, the height of the first movable assembly 5 and the second movable assembly 6 is lowered by the lifting assembly 4, and the monorail crane 1 can continue to operate.

[0075] When the lifting assembly 4 raises the height of the second installation box 62 and the new battery 2, since the lifting assembly 4 and the first moving assembly 5 operate together, the conveyor belt 53 is in a moving state, which will drive the second installation box 62 to move horizontally toward the rotating rod 91, and the rotating rod 91 is limited by the limiting rod 92, so that the rotating rod 91 cannot rotate, so that the rotating rod 91 abuts against the second installation box 62, and the second installation box 62 and the conveyor belt 53 slide relative to each other, so that the horizontal position of the second installation box 62 and the new battery 2 remains unchanged.

[0076] During the replacement of the battery 2 of the monorail crane 1, after the old battery 2 falls into the first installation box 61, if the old battery 2 has electrolyte loss due to long-term use, the weight of the old battery 2 is relatively small, resulting in the slide plate 64 in the first installation box 61 compressing the first spring 65 to slide downward for a smaller distance, so that less liquid enters the first rodless cavity 812 from the first installation box 61, and the extension distance of the adjusting telescopic rod 81 is shorter, so that the distance between the first magnetic wheel 72 and the second magnetic wheel 74 is farther, and the first magnetic wheel 72 and the second magnetic wheel 74 do not generate interaction force, that is, the first moving component 5 does not work, thereby reminding the operator that the old battery is damaged and the operator should take corresponding measures.

[0077] The implementation principle of a monorail battery replacement device in the embodiment of the present application is as follows:

[0078] When the power stored in the old battery 2 is exhausted and needs to be replaced, the monorail crane 1 runs along the track to the charging position of the battery 2, and the lifting component 4 operates independently to raise the height of the conveyor belt 53 and the first installation box 61. When the first installation box 61 reaches the bottom of the old battery 2 and the old battery 2 abuts against the slide plate 64 in the first installation box 61, the lifting component 4 causes the first installation box 61 to continue to move upward, and the old battery 2 compresses the first spring 65 in the first installation box 61 so that the slide plate 64 in the first installation box 61 slides downward relative to the first installation box 61, so that the magnetic block 63 on the first installation box 61 is at the same height as the pin 33, thereby opening the James coupler 3, and under the action of its own gravity, the old battery 2 falls onto the slide plate 64 in the first installation box 61, and the plug 21 slides downward away from the socket 11, completing the removal of the old battery 2.

[0079] When the old battery 2 is removed, the lifting assembly 4 and the first moving assembly 5 operate together to lower the height of the conveyor belt 53, and at the same time, the first installation box 61 and the second installation box 62 move in the horizontal direction, so that the first installation box 61 is away from the installation position of the battery 2 of the monorail crane 1, and then the lifting assembly 4 and the first moving assembly 5 operate in the reverse direction, so that the height of the first installation box 61 and the second installation box 62 is increased, and the first installation box 61 and the second installation box 62 move in the reverse direction in the horizontal direction, and cooperate with the limit assembly 9, so that the second installation box 62 is located on the monorail Below the battery 2 installation location of the crane 1, when the second installation box 62 rises in height, the plug 21 is first inserted into the socket 11, and then the fixed hook 31 abuts against the movable hook 32. At this time, the second installation box 62 and the new battery 2 continue to rise in height through the lifting component 4, so that the magnetic block 63 on the second installation box 62 and the pin 33 are at the same height, so that when the pin 33 is inserted into the fixed hook 31, the Jane's coupler 3 is locked, completing the installation of the new battery 2. Finally, the height of the first movable component 5 and the second movable component 6 is lowered through the lifting component 4, and the monorail crane 1 can continue to operate.

[0080] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
