Description

Technical Field

[0001] This utility model belongs to the technical field of mobile energy storage equipment, specifically relating to a chassis for self-loading and unloading of energy storage cabins. Background Technology

[0002] Energy storage containers have advantages such as high mobility and environmental adaptability, good versatility, and convenience and flexibility, and are widely used in many military and civilian fields such as communication command, emergency rescue, medical care, and life support. However, due to the large weight of energy storage containers, they require the use of cranes, forklifts, or other lifting equipment, or rely on special loading vehicles to complete the loading and unloading of equipment when transported and deployed, which requires a large construction area and high transportation and hoisting costs.

[0003] Existing self-loading and unloading devices for modular shelters mostly employ retractable vertical support legs attached to the shelter body. For example, CN216109932U discloses a self-loading and unloading modular shelter with four concealed compartments on the main body, and vertical hydraulic retractable support legs installed on the inner side of the compartment door on the other side of the concealed compartments. This method lacks versatility, requiring space within the shelter for the retractable support leg system and the necessary power drive mechanism, which significantly limits the arrangement of other equipment inside the shelter. Utility Model Content

[0004] The purpose of this utility model is to provide a chassis for self-loading and unloading of energy storage containers, so as to avoid occupying the space inside the energy storage container and avoid affecting the layout of equipment inside the container while realizing self-loading and unloading of energy storage containers.

[0005] This utility model discloses a chassis for self-loading and unloading energy storage container, comprising a chassis body with container mounting holes, a command input module, a control module, a front lifting device installed in a first housing, a rear lifting device installed in a second housing, and a power supply module. The first housing is installed at the front of the chassis body, and the second housing is installed at the rear of the chassis body. The front lifting device has the same structure as the rear lifting device, both including an oil supply module, a left lifting mechanism, and a right lifting mechanism. The left lifting mechanism has the same structure as the right lifting mechanism, both including a horizontal deployment hydraulic cylinder and a vertical lifting hydraulic cylinder connected to the oil supply module via an oil circuit. The piston rod end lug of the horizontal deployment hydraulic cylinder is connected to the vertical lifting mechanism. The cylinder body of the vertical lifting hydraulic cylinder is hinged at the end of the cylinder body; the command input module is electrically connected to the control module, and the control module is electrically connected to two oil supply modules. The control module can control the two oil supply modules to extend and retract the piston rods of the corresponding horizontally deploying hydraulic cylinders and the corresponding vertically lifting hydraulic cylinders according to the operation commands input by the command input module. The extension of the piston rod of the horizontally deploying hydraulic cylinder can completely push the corresponding vertically lifting hydraulic cylinder out of the first housing and the second housing. After the vertically lifting hydraulic cylinder is completely pushed out, it can rotate relative to the piston rod of the horizontally deploying hydraulic cylinder. The piston rods of the vertically lifting hydraulic cylinder and the horizontally deploying hydraulic cylinder can be kept vertically fixed by the limiting component. The extension of the piston rods of the four vertically lifting hydraulic cylinders can form the four support legs of the chassis body.

[0006] Preferably, support end plates are installed at the bottom of each of the four support legs. The support end plates are used to reduce the pressure on the support legs and prevent slippage. The limiting component is a limiting pin. A limiting hole is opened on the end lug of the piston rod of the horizontally deploying hydraulic cylinder, and a corresponding limiting hole is opened on the end lug of the cylinder body of the vertically lifting hydraulic cylinder. The limiting pin passes through the two limiting holes to keep the piston rods of the vertically lifting hydraulic cylinder and the horizontally deploying hydraulic cylinder vertically fixed.

[0007] The present invention describes another chassis for self-loading and unloading energy storage containers, comprising a chassis body with a container mounting hole, a command input module, a control module, a front lifting device installed in a first housing, a rear lifting device installed in a second housing, and a power supply module. The first housing is installed at the front of the chassis body, and the second housing is installed at the rear of the chassis body. The front lifting device has the same structure as the rear lifting device, both including an oil supply module, a left lifting mechanism, and a right lifting mechanism. The left lifting mechanism has the same structure as the right lifting mechanism, both including a linear motor and a vertical lifting hydraulic cylinder. The vertical lifting hydraulic cylinder is connected to the oil supply module via an oil circuit. The end lug of the output shaft of the linear motor is connected to the end of the cylinder body of the vertical lifting hydraulic cylinder. The chassis features hinged lugs; the command input module is electrically connected to the control module, which in turn is electrically connected to four linear motors. The control module controls the extension and retraction of the output shafts of the four linear motors according to the operation commands input by the command input module. It is also electrically connected to two oil supply modules, which, according to the operation commands input by the command input module, control the piston rods of the corresponding vertical lifting hydraulic cylinders to extend and retract. The extension of the linear motor's output shaft completely pushes the corresponding vertical lifting hydraulic cylinder out of the first and second housings. After being completely pushed out, the vertical lifting hydraulic cylinder can rotate relative to the output shaft of the linear motor. Limiting devices ensure that the vertical lifting hydraulic cylinder and the output shaft of the linear motor remain perpendicular and fixed. The extension of the piston rods of the four vertical lifting hydraulic cylinders forms the four support legs of the chassis body.

[0008] Preferably, support end plates are installed at the bottom of each of the four support legs. The support end plates are used to reduce the pressure on the support legs and prevent slippage. The limiting component is a limiting pin. A limiting hole is opened on the end lug of the output shaft of the linear motor, and a corresponding limiting hole is opened on the end lug of the cylinder body of the vertical lifting hydraulic cylinder. The limiting pin passes through the two limiting holes to keep the vertical lifting hydraulic cylinder and the output shaft of the linear motor perpendicular and fixed.

[0009] Preferably, a hinged cover plate is hinged to the edge of the orifice for the vertical lifting hydraulic cylinder of the right lifting mechanism of the front lifting device on the right side of the first housing; a hinged cover plate is hinged to the edge of the orifice for the vertical lifting hydraulic cylinder of the left lifting mechanism of the front lifting device on the left side of the first housing; a hinged cover plate is hinged to the edge of the orifice for the vertical lifting hydraulic cylinder of the right lifting mechanism of the rear lifting device on the right side of the second housing; and a hinged cover plate is hinged to the edge of the orifice for the vertical lifting hydraulic cylinder of the left lifting mechanism of the rear lifting device on the left side of the second housing. When the vertical lifting hydraulic cylinder is not extended, the hinged cover plate covers the corresponding orifice; when the vertical lifting hydraulic cylinder is extended, the hinged cover plate is opened and flipped outward by 90° by the corresponding vertical lifting hydraulic cylinder. The hinged cover plate can act as a shield to prevent debris near the chassis from entering the first and second housings and affecting the operation of the left and right lifting mechanisms.

[0010] Preferably, the instruction input module includes a remote control transmitter and a corresponding remote control receiver connected via wireless communication. The remote control transmitter is equipped with a horizontal deployment adjustment switch and a vertical lifting adjustment switch, and the remote control receiver is electrically connected to the control module. Operation instructions are sent via the remote control transmitter. After receiving the operation instructions, the remote control receiver transmits them to the control module. The control module then controls the corresponding components to operate according to the operation instructions, making the operation simple, quick, and convenient.

[0011] Compared with the prior art, this utility model has the following advantages: (1) The energy storage container is installed on the chassis through the container installation hole. The control module, front lifting device and rear lifting device realize the self-loading and unloading (i.e. self-lifting) of the energy storage container. The energy storage container does not need to be hoisted when it is installed. There is no need to rent or buy cranes, forklifts and other equipment to assist in getting on and off the vehicle, which saves transportation costs and requires a small construction area.

[0012] (2) All operating mechanisms related to loading and unloading are integrated into the chassis, which do not occupy the space inside the energy storage container and do not affect the layout of equipment inside the energy storage container. If the operating mechanisms related to loading and unloading experience malfunctions such as leakage, they will not affect the main function of the energy storage container.

[0013] (3) The chassis adopts a modular and universal design, which solves the problem of on-site self-loading and unloading of energy storage cabins, while improving applicability. It is also easy to operate and suitable for promotion and application. Attached Figure Description

[0023] Example 1: As Figures 1 to 7As shown, the chassis for self-loading and unloading of the energy storage container in this embodiment includes a chassis body 1, a command input module 2, a control module 3, a front lifting device installed in the first housing 4, a rear lifting device installed in the second housing 5, and a power supply module 13 for power supply. Each of the four corners of the chassis body 1 has a container mounting hole 101. The first housing 4 is installed at the front of the chassis body 1, and the second housing 5 is installed at the rear of the chassis body 1. The command input module 2 includes a remote control transmitter 21 and a remote control receiver 22 connected by wireless communication. The remote control transmitter 21 is equipped with a horizontal deployment adjustment switch and a vertical lifting adjustment switch. The remote control receiver 22, the control module 3, and the power supply module 13 are installed on the chassis body 1. The structure of the front lifting device is the same as that of the rear lifting device, both including an oil supply module 6 and parallel left and right lifting mechanisms. The structure of the left lifting mechanism is the same as that of the right lifting mechanism, both including a horizontally deploying hydraulic cylinder 7 and a vertically lifting hydraulic cylinder 8 connected to the oil supply module 6 via an oil circuit. The end lug of the piston rod 71 of the horizontally deploying hydraulic cylinder 7 is hinged to the end lug of the cylinder body of the vertically lifting hydraulic cylinder 8. A limit hole is provided on the end lug of the piston rod 71 of the horizontally deploying hydraulic cylinder 7, and a corresponding limit hole is provided on the end lug of the cylinder body of the vertically lifting hydraulic cylinder 8. The power module 13 is electrically connected to the remote control receiver 22, the control module 3, and the oil supply module 6, providing power to the remote control receiver 22, the control module 3, and the electrical equipment (such as oil pumps, solenoid valves, etc.) within the oil supply module 6. The remote control transmitter 21 is powered by a battery. The remote control receiver 22 is electrically connected to the control module 3, and the control module 3 is electrically connected to the two oil supply modules 6. The control module 3 can control the two oil supply modules 6 to extend and retract the piston rod of the corresponding horizontally deploying hydraulic cylinder 7 and extend and retract the piston rod 81 of the corresponding vertically lifting hydraulic cylinder 8 according to the operation command input by the remote control receiver 22 (issued by the remote control transmitter 21). The extension of the piston rod of the horizontally deploying hydraulic cylinder 7 can completely push the corresponding vertically lifting hydraulic cylinder 8 out of the first housing 4 and the second housing 5 (the left and right sides of the first housing 4 and the left and right sides of the second housing 5 are provided with holes for the vertically lifting hydraulic cylinder 8 to be pushed out). After the vertically lifting hydraulic cylinder 8 is completely pushed out, it can rotate relative to the piston rod 71 of the horizontally deploying hydraulic cylinder 7. The limit pin 11 passes through the two limit holes to keep the vertically lifting hydraulic cylinder 8 and the piston rod 71 of the horizontally deploying hydraulic cylinder 7 vertically fixed. The extension of the piston rod 81 of the four vertically lifting hydraulic cylinders 8 can form the four support legs of the chassis body 1. The bottom of the four support legs can be equipped with support end plates 10.A hinge cover plate 9 is hinged to the edge of the orifice of the vertical lifting hydraulic cylinder 8 of the right lifting mechanism of the front lifting device on the right side of the first housing 4; a hinge cover plate 9 is hinged to the edge of the orifice of the vertical lifting hydraulic cylinder 8 of the left lifting mechanism of the front lifting device on the left side of the first housing 4; a hinge cover plate 9 is hinged to the edge of the orifice of the vertical lifting hydraulic cylinder 8 of the right lifting mechanism of the rear lifting device on the right side of the second housing 5; a hinge cover plate 9 is hinged to the edge of the orifice of the vertical lifting hydraulic cylinder 8 of the left lifting mechanism of the rear lifting device on the left side of the second housing 5.

[0024] The energy storage container 14 is mounted on the chassis through four container mounting holes 101.

[0025] The operator presses the horizontal deployment adjustment switch on the remote transmitter 21 upwards to send a command to the remote receiver 22 to extend the piston rod of the horizontal deployment hydraulic cylinder. Stopping the upward press of the horizontal deployment adjustment switch during the extension process sends a command to the remote receiver 22 to stop the extension. The operator presses the horizontal deployment adjustment switch on the remote transmitter 21 downwards to send a command to retract the piston rod of the horizontal deployment hydraulic cylinder. Stopping the downward press of the horizontal deployment adjustment switch during the retraction process sends a command to the remote receiver 22 to stop the retraction. The operator presses the vertical lifting adjustment switch on the remote transmitter 21 upwards to send a command to extend the piston rod of the vertical lifting hydraulic cylinder. Stopping the upward press of the vertical lifting adjustment switch during the extension process sends a command to the remote receiver 22 to stop the extension. The operator presses down the vertical lifting adjustment switch on the remote transmitter 21 to send a command to the remote receiver 22 to shorten the piston rod of the vertical lifting hydraulic cylinder. Stopping the downward press of the vertical lifting adjustment switch during the shortening process sends a command to the remote receiver 22 to stop the shortening. After receiving the above operation commands, the remote receiver 22 transmits them to the control module 3. The control module 3 then controls the oil supply module 6 to cause the horizontal deployment hydraulic cylinder 7 and the vertical lifting hydraulic cylinder 8 to perform corresponding actions.

[0026] In the initial state, the front lifting device is folded into the first housing 4, and the rear lifting device is folded into the second housing 5. When the energy storage container 14 is transported to the designated location by the transport vehicle 15 and the container lowering operation begins, the control module 3 controls the two oil supply modules 6 according to the operation command to extend the piston rods 71 ​​of the four horizontally deploying hydraulic cylinders 7, and slowly pushes out the corresponding four vertically lifting hydraulic cylinders 8 from the first housing 4 and the second housing 5. When the four vertically lifting hydraulic cylinders 8 are fully pushed out and part of the piston rods 71 ​​of the four horizontally deploying hydraulic cylinders 7 extends out of the first and second housings, the control module 3 controls the two oil supply modules 6 according to the operation command to stop the extension of the piston rods 71 ​​of the four horizontally deploying hydraulic cylinders 7. The four vertically lifting hydraulic cylinders 8 rely on gravity to rotate downward along the hinge axis until they are perpendicular to the ground. At this point, four limiting pins 11 are inserted into the corresponding limiting holes to keep the piston rods 711 of the vertical lifting hydraulic cylinder 8 and the horizontal unfolding hydraulic cylinder 7 vertically fixed, and the support end plate 10 is installed at the end of the piston rod 81 of the vertical lifting hydraulic cylinder 8. Then, the control module 3 controls the two oil supply modules 6 according to the operation command to extend the piston rods 81 of the four vertical lifting hydraulic cylinders 8 to form the four support legs of the chassis body 1. As the piston rods 81 of the vertical lifting hydraulic cylinders 8 continue to extend, they will drive the upper chassis body 1 and the energy storage container 14 to move upward (i.e., start lifting). When the lifting stroke is reached, the control module 3 controls the two oil supply modules 6 according to the operation command to stop the extension of the piston rods 81 of the four vertical lifting hydraulic cylinders 8, the transport vehicle separates from the chassis, and the transport vehicle drives away. Finally, the control module 3 controls the two oil supply modules 6 according to the operation command to shorten the piston rods 81 of the four vertical lifting hydraulic cylinders 8 until the piston rods 81 return to the initial state and stop, and the lowering operation is completed.

[0027] When the energy storage container 14 needs to be moved, the control module 3 controls the two oil supply modules 6 according to the operation command to extend the piston rods 81 of the four vertical lifting hydraulic cylinders 8, thereby driving the upper chassis body 1 and the energy storage container 14 to move upward (i.e., start lifting). After reaching the lifting stroke, the transport vehicle 15 drives in and aligns with the chassis body 1; then, the control module 3 controls the two oil supply modules 6 according to the operation command to shorten the piston rods 81 of the four vertical lifting hydraulic cylinders 8, and the energy storage container 14 and the chassis body 1 fall onto the transport vehicle 15, and the four vertical... The piston rod 81 of the lifting hydraulic cylinder 8 continues to shorten until the four support legs are off the ground and then stops; then the four limit pins 11 are removed and the four support end plates 10 are removed; then, the control module 3 controls the two oil supply modules 6 according to the operation command to make the piston rod 81 of the four vertical lifting hydraulic cylinders 8 continue to shorten back to the initial state and then stops; finally, the control module 3 controls the two oil supply modules 6 according to the operation command to make the piston rod 71 of the four horizontal unfolding hydraulic cylinders 7 shorten back to the initial state and then stops, and the vertical lifting hydraulic cylinder 8 returns to the first housing 4 and the second housing 5.

[0028] Example 2: Figure 8 , Figure 9 As shown, the chassis for self-loading and unloading of the energy storage container in this embodiment has most of the same structure as in Embodiment 1, except that: both the left and right lifting mechanisms include a linear motor 12 and a vertical lifting hydraulic cylinder 8. The vertical lifting hydraulic cylinder 8 is connected to the oil supply module 6 via an oil circuit. The end lug of the output shaft of the linear motor 12 is hinged to the end lug of the cylinder body of the vertical lifting hydraulic cylinder 8. A limit hole is provided on the end lug of the output shaft of the linear motor 12, and a corresponding limit hole is provided on the end lug of the cylinder body of the vertical lifting hydraulic cylinder 8. The power module 13 is electrically connected to the remote control receiver 22, the control module 3, the four linear motors 12, and the two oil supply modules 6, providing power to the remote control receiver 22, the control module 3, the linear motors 12, and the electrical equipment (such as oil pumps, solenoid valves, etc.) in the oil supply module 6. The control module 3 is electrically connected to four linear motors 12. The control module 3 can control the extension and retraction of the output shafts of the four linear motors 12 according to the operation commands input by the remote control receiver 22. The extension of the output shaft of the linear motor 12 can completely push the corresponding vertical lifting hydraulic cylinder 8 out of the first housing 4 and the second housing 5. After the vertical lifting hydraulic cylinder 8 is completely pushed out, it can rotate relative to the output shaft of the linear motor 12. The limit pin 11 passes through two limit holes to keep the vertical lifting hydraulic cylinder 8 and the output shaft of the linear motor 12 perpendicular and fixed.

[0029] The operator presses the horizontal extension adjustment switch on the remote transmitter 21 upwards to send an extension command to the output shaft of the linear motor to the remote receiver 22. Stopping the upward press of the horizontal extension adjustment switch during the extension process sends a stop command to the output shaft of the linear motor to the remote receiver 22. The operator presses the horizontal extension adjustment switch on the remote transmitter 21 downwards to send a retraction command to the output shaft of the linear motor to the remote receiver 22. Stopping the downward press of the horizontal extension adjustment switch during the retraction process sends a stop command to the output shaft of the linear motor to the remote receiver 22.

[0030] Initially, the front lifting device is folded into the first housing 4, and the rear lifting device is folded into the second housing 5. When the energy storage container 14 is transported to the designated location by the transport vehicle and the unloading operation begins, the control module 3 controls the output shafts of the four linear motors 12 to extend according to the operation command, slowly pushing out the corresponding four vertical lifting hydraulic cylinders 8 from the first housing 4 and the second housing 5. When the four vertical lifting hydraulic cylinders 8 are fully extended and part of the output shafts of the four linear motors 12 extend out of the first and second housings, the control module 3 controls the output shafts of the four linear motors 12 to stop extending according to the operation command. The four vertical lifting hydraulic cylinders 8 rotate downward along the hinge axis until they are perpendicular to the ground under the action of gravity. At this time, the four limit pins 11 are inserted into the corresponding limit holes to keep the vertical lifting hydraulic cylinders 8 and the output shafts of the linear motors 12 vertically fixed, and the support end plate 10 is installed at the end of the piston rod 81 of the vertical lifting hydraulic cylinder 8.

[0031] When the energy storage container 14 needs to be moved and the piston rods 81 of the four vertical lifting hydraulic cylinders 8 shorten back to the initial state, the control module 3 controls the output shafts of the four linear motors 12 to shorten to the initial state and stop, and the vertical lifting hydraulic cylinders 8 return to the first housing 4 and the second housing 5.
