[0026] Figure 2 is a schematic structural diagram of the furnace lid lifting device of the present utility model. Specific embodiments

[0027] Now, the patent of the present utility model will be further described in detail with reference to the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present utility model in a schematic manner. Therefore, they only show the parts related to the present utility model.

[0028] The embodiment of the present application provides a large battery adiabatic calorimetry system with a furnace lid lifting device, which includes a calorimeter main body and a furnace lid lifting device.

[0029] As Figure 1 shown, in the embodiment of the present application, the calorimeter main body Ⅰ is connected to the furnace lid lifting device Ⅱ. The furnace lid lifting device is fixed on the bottom plate, and the bottom plate is provided with universal wheels, which is convenient for the movement of the calorimeter main body.

[0030] As Figure 2 shown, the furnace lid lifting device includes a lifting mechanism and a translation mechanism. The lifting mechanism is vertically arranged on the translation mechanism, and its top is connected to the furnace lid 9 of the calorimeter main body.

[0031] The lifting mechanism includes a support frame 7, a linear motion actuator and a connecting rod 8. The linear motion actuator is fixed on the two support plates 7, and the linear motion actuator is fixed on the translation mechanism. One end of the linear motion actuator is connected to the support frame 7, and the other end is connected to the first driving mechanism. The support frame 7 is connected to the furnace lid 9 through the connecting rod 8.

[0032] The translation mechanism includes a pair of movable support plates 1 and a transmission plate 2. The transmission plate 2 is installed between the two movable support plates 1. The transmission plate 2 is connected to one end of the ball screw 3 through a nut 4 and an adapter. The other end of the ball screw 3 is connected to a second driving mechanism, which drives the ball screw to generate a rotational motion.

[0033] The ball screw 3 includes a screw and a ball nut. The ball nut is provided with balls. The transmission plate 2 can effectively transmit power and also play a role in supporting and stabilizing the entire lifting device structure, ensuring the stability and reliability of the lifting device.

[0034] The adapter is often used to connect transmission elements with different diameters or different types, such as the transition between the output shaft of an electric driving mechanism and the transmission component of a lifting beam.

[0035] In the embodiment of the present application, both the first driving mechanism and the second driving mechanism include a motor and a speed reducer 5. The motor provides power and is converted into a low-speed and high-torque output suitable for lifting operations through the speed reducer 5. The linear motion actuator is an electric cylinder 6. Guide rails with sliders are provided at the bottoms of the two support plates 1, which can effectively support and stabilize the frame structure of the furnace cover lifting device. The bottom of the electric cylinder 6 and above the slider is the support plate 1. The support plate 1 is used to support the electric cylinder 6. The electric cylinder 6 is connected to the support plate 1 through components such as pin shafts. This connection method can provide a more stable connection and can withstand greater loads and more complex motion requirements.

[0036] The nut 4 is used to connect between the output shaft of the electric drive mechanism (such as a motor or an electric cylinder) and the transmission component (such as a lead screw or a transmission rod) of the lifting beam. Through the threaded structure, the rotation of the electric drive mechanism can be effectively transmitted to the lifting beam, thereby driving the lifting motion of the furnace cover 9.

[0037] The electric cylinder 6 is connected to the furnace cover 9 through a lead screw arranged inside. The support frame 7 is connected to the furnace cover 9 through a connecting rod 8. The two support plates 1 on both sides are connected through a transmission plate 2. The transmission plate 2 is connected to the ball screw 3 through a nut 4 and an adapter. The end of the ball screw 3 is connected to a horizontal motor and a speed reducer 5. Driven by the motor and the speed reducer 5, the electric cylinder 6 can directly push the furnace cover 9 or the component connected to the furnace cover to achieve the lifting function. The ball screw 3 drives the slider at the bottom of the support plate 1 to achieve horizontal movement on the guide rail. Thus, the lifting and translation of the furnace cover 9 are realized, and then the battery sample can be placed, ensuring the safety of the experimental personnel.

[0038] Driven by the motor, the electric cylinder 6 converts the rotational motion into a linear motion, enabling the electric cylinder 6 to push or pull the load connected to it and achieve precise movement in a straight line direction. The motor serves as the power source to drive the electric cylinder 6. In the adiabatic calorimetry system, in order to enhance the stability and balance of the lifting device, a design of arranging two motors side by side is adopted. This layout can balance the load distribution and reduce the inclination or uneven movement of the furnace cover 9 during the lifting process. The main function of the speed reducer 5 is to reduce the output speed of the motor and increase the torque output, so as to better control the movement of the furnace cover 9, achieve more precise position control, avoid the problem of motion inertia caused by the too fast speed of the motor, and ensure that the furnace cover 9 stops stably at the required position.

[0039] In addition, the electric cylinder 6 can be replaced by a hydraulic cylinder. The piston is pushed upward by the hydraulic pressure of the oil. This linear motion can be used to push or pull the load connected to the piston, realizing the linear motion of the working mechanism. The ball screw 3 consists of balls and a screw shaft. The balls roll in the helical groove of the screw shaft, converting the rotational motion into a linear motion. Compared with the ordinary screw drive, the ball screw 3 has a higher transmission efficiency and can more quickly realize the linear motion of a large load. The transmission plate 2 is used to transmit power and motion, connecting different mechanical components or assemblies, enabling them to move in a coordinated manner. As part of the transmission system, it transmits power from one position to another.

[0040] In the embodiment of the present application, the motor is started through the control system, and the electric cylinder 6 is driven by the motor to raise the furnace cover from the closed position 9 to the required open height. The horizontal ball screw 3 is driven by the horizontal motor. The balls roll in the helical groove of the screw shaft, converting the rotational motion into an axial motion. The screw shaft drives the transmission plate 2 to achieve horizontal movement. During this process, the transmission plate 2 will maintain horizontal and stable movement, ensuring that the furnace cover 9 will not tilt or shake during movement. After the battery is installed in the measuring instrument furnace cavity, the horizontal motor is started through the control system to drive the ball screw 3 to rotate. The ball screw 3 pushes the transmission plate 2, and the furnace cover 9 is horizontally moved above the furnace top through the guide rail. Finally, the electric cylinder 6 is started through the control system to lower the furnace cover 9 to the closed state.

The matters not covered in the present utility model belong to the common general knowledge of those skilled in the art.
