Description

Technical Field

[0001] The present invention relates to the technical field of arrangement or installation of electric power devices, and in particular to a battery quick-entry device. Background Art

[0002] In the field of new energy storage, it is necessary to install energy storage batteries in the battery racks of container-type container houses. Since the weight of the batteries is generally around 300 kilograms, the number of batteries installed in each container house is between dozens and hundreds. The number is large, involving the lifting and propulsion of the batteries, which makes the installation difficult and there are hidden dangers in the installation.

[0003] The existing battery loading device is generally transported to the battery compartment by a lifting mechanism. The lifting mechanism is provided with a supporting platform for supporting the battery. The battery is placed on the supporting platform, and the battery is lifted to the entrance of the battery compartment by the lifting mechanism on the supporting platform. The battery is pushed into the battery compartment with manual assistance, but the manual pushing stroke is not stable enough, and when the relative position of the supporting platform and the battery compartment deflects, the battery is easily deflected when manually pushed, making it difficult to accurately fine-tune the battery status. It is also time-consuming, labor-intensive, and labor-intensive. Summary of the invention

[0004] The purpose of the present invention is to provide a battery rapid entry device to solve the problems that the existing battery entry device is easily deflected by manual assisted propulsion, is difficult to accurately fine-tune the battery state, and is time-consuming, labor-intensive and labor-intensive.

[0005] The battery rapid entry device of the present invention adopts the following technical solution: a battery rapid entry device, including a support platform, on which a propulsion mechanism for pushing the battery into the cabin is arranged, the support platform has a constraint structure for constraining the battery travel trajectory perpendicular to the propulsion direction, the constraint structure satisfies the requirement that the battery can float and deflect perpendicular to the propulsion direction, and the propulsion mechanism has a propulsion member for deflecting along with the change of the battery posture to push the battery into the battery cabin.

[0006] The battery rapid cabin entry device of the present invention is a newly designed battery rapid cabin entry device. When the battery rapid cabin entry device of the present invention is used, the battery is placed on the supporting platform, and the battery is moved to the entrance of the battery cabin along the propulsion direction under the action of the propulsion mechanism. When the supporting platform and the battery cabin are not facing each other in position or direction, the battery contacts the battery cabin wall during the propulsion process and is blocked by the cabin wall and deflected relative to the original propulsion direction, the propulsion member deflects accordingly with the change of the battery posture, and still maintains a thrust force on the battery in the deflection direction to ensure that the battery is effectively and quickly pushed into place.

[0007] Furthermore, the propulsion member is a push rod arranged in the horizontal direction, and the middle part of the push rod is rotatably connected to the propulsion mechanism. The push rod has a large contact area with the battery, a large force range on the battery during the propulsion process, and a relatively smooth propulsion process, ensuring effective and rapid propulsion into place.

[0008] Furthermore, the constraint structure includes two vertical plates arranged at a relative interval perpendicular to the propulsion direction, the propulsion mechanism is located in the middle of the two vertical plates, and the length of the push rod is less than the distance between the two vertical plates. The vertical plates constrain the battery to move within the vertical plates, ensuring the accuracy of the propulsion process. The propulsion mechanism is located in the middle of the two vertical plates, ensuring that the battery is evenly stressed during the propulsion process, and the trajectory of the battery propulsion process is stable. The length of the push rod is less than the distance between the two vertical plates and does not contact the vertical plates to generate friction, ensuring that the propulsion process is more labor-saving and convenient.

[0009] Furthermore, the support platform is provided with guide rails for supporting the battery to slide in parallel and spaced along the propulsion direction on both sides of the propulsion mechanism. The support platform is provided with guide rails, and the friction of the battery moving on the guide rails is small, making the propulsion more labor-saving and convenient.

[0010] Furthermore, there are two guide rails and they are symmetrically arranged on both sides of the propulsion mechanism, and the two vertical plates are respectively arranged on the sides of the two guide rails that are far away from each other. There are two guide rails and they are symmetrically arranged on both sides of the propulsion mechanism to ensure that the battery is supported stably during the movement. The battery moves on the guide rails, and the two vertical plates are respectively arranged on the sides of the two guide rails that are far away from each other, which has a better restraining effect on the battery. This arrangement is easy to manufacture and saves materials.

[0011] Furthermore, the guide rail is an "J"-shaped profile, the open end of the "J"-shaped profile is connected to the support platform, and the closed end of the "J"-shaped profile is used to support the battery to slide. The "J"-shaped profile includes two vertical edges to ensure the stability of the support, and the open end of the "J"-shaped profile includes a folded edge for easy assembly with the support platform. The closed end surface of the "J"-shaped profile is smooth, and the friction of the battery is small during the movement of the battery on it, ensuring that the battery is labor-saving and convenient during the propulsion process, and the movement is stable.

[0012] Furthermore, the propulsion mechanism includes a propulsion screw nut mechanism, the propulsion screw nut mechanism is connected to a propulsion motor, and the propulsion motor and the propulsion screw nut mechanism are arranged side by side on the support platform in the propulsion direction. The propulsion motor drives the propulsion screw nut mechanism to drive the battery to move, which has a simple structure and is easy to operate. The propulsion motor and the propulsion screw nut mechanism are arranged side by side on the support platform in the propulsion direction to reduce the length of the support platform and make rational use of space.

[0013] Furthermore, the support platform is a lifting support platform, which is more convenient to use in adapting to battery compartments of different heights.

[0014] Furthermore, the support platform is provided with lifting screw nut mechanisms on both sides, and the lifting screw nut mechanisms share a lifting motor through a coupling to drive the support platform to lift. One motor drives the lifting screw nut mechanism to rotate, ensuring the synchronization of the lifting screw nut mechanism and ensuring that the support platform is stable during the lifting process.

[0015] Furthermore, the lifting screw nut mechanism is fixed on the support frame, and guide columns are arranged on both sides of the support platform on the support frame, and the support platform is slidably arranged on the guide columns. When the support platform is lifted or lowered on the lifting screw nut mechanism, the moving nut and the screw rotate relative to each other, and the guide columns are arranged to ensure the stability of the support platform during the lifting process.

[0021] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0022] Specific embodiment 1 of the battery quick entry device of the present invention:

[0023] The battery quick entry device of the present invention is as follows Figure 1-4As shown, a battery rapid entry device includes a support frame 1 and a support platform 2. A lifting motor 11 is arranged at the bottom end of the support frame 1. The output shaft of the lifting motor 11 is switched to both sides of the bottom end of the support frame 1 through a coupling. Couplings are arranged on both sides of the bottom end of the support frame 1 to switch the output shaft to the four corners of the bottom end of the support frame 1 again. Four longitudinal lifting screw nut mechanisms 12 are connected to the four corners of the bottom end of the support frame 1 through couplings. The four longitudinal lifting screw nut mechanisms 12 are surrounded by a rectangular structure. The support platform 2 is lifted and lowered in the support frame 1 by sliding guided by the movable nut of the lifting screw nut mechanism 12.

[0024] The support platform 2 includes a rectangular bottom plate and side plates arranged on the edge of the bottom plate along the length direction. The support platform 2 is located inside the support frame 1 and partially cantilevers out of the support frame 1 along the length direction. The support platform 2 is used to support and constrain the battery. A propulsion mechanism for pushing the battery into the cabin is provided on the support platform 2. The propulsion mechanism has a propulsion member for deflecting along with the change of the battery posture to push the battery into the battery cabin. Specifically, the propulsion member includes a push rod 21 arranged along the horizontal direction. The middle part of the push rod 21 is rotatably mounted on the propulsion mechanism through a rotating shaft. The push rod 21 pushes the battery into the cabin. When the battery is deflected during the propulsion process and the battery cabin, the push rod 21 can deflect along with the change of the battery posture. The push rod 21 is always in contact with the surface of the battery to ensure effective and rapid propulsion into place.

[0025] Specifically, the propulsion mechanism includes a propulsion screw nut mechanism 25, a push rod 21 is arranged on the propulsion screw nut mechanism 25, a propulsion motor 24 is connected to the propulsion screw nut mechanism 25, the propulsion motor 24 and the propulsion screw nut mechanism 25 are arranged side by side on the support platform 2 in the propulsion direction, and the propulsion screw nut mechanism 25 and the propulsion motor 24 are connected by a synchronous belt 26. This arrangement can reduce the length of the support platform 2 and make rational use of space. The upper ends of the support platform 2 are respectively provided with a "J"-shaped profile 22 along the propulsion direction. The "J"-shaped profile 22 includes two vertical edges to ensure the stability of the support. The folded edge of the open end of the "J"-shaped profile 22 is assembled and connected with the support platform 2. The closed end of the "J"-shaped profile 22 is smooth for battery sliding. The friction of the battery is small during the movement of the battery on it, ensuring that the battery is labor-saving and convenient during the propulsion process and stable movement. Vertical plates 23 perpendicular to the propulsion direction are arranged at positions far apart on the "J"-shaped profile 22. The battery slides guided by the "J"-shaped profile 22. The battery is located inside the two vertical plates 23. The two vertical plates 23 constrain the battery travel trajectory. The distance between the two vertical plates 23 is slightly less than or equal to the width of the battery compartment, which ensures that the battery can float and deflect perpendicular to the propulsion direction, ensuring that the sliding friction between the battery and the push rod 21 on the "J"-shaped profile 22 is small, ensuring that the propulsion process is labor-saving and efficient.

[0026] Specifically, the support frame 1 is a tubular frame. The support frame 1 is provided with support columns on both sides of the frame in the length direction of the support platform 2. The support frame 1 is provided with a guide column 15 between the two lifting screws in the length direction of the support platform 2. The support platform 2 and the guide column 15 are set to slide in a guided manner. Adjustable feet 13 are provided on the columns above the four corners of the bottom end of the support frame 1. The adjustable feet 13 can adjust the height of the support frame 1 to make the lifting range of the support platform 2 larger. When the range is not too high, it can be retracted to save space, and the stability of the support frame 1 can be adjusted to ensure the stability and balance of the support platform 2. Moving pulleys 14 are provided on the horizontal columns below the four corners of the bottom end of the support frame 1. The moving pulleys 14 facilitate moving the support frame 1 to different positions, which is labor-saving and easy to use.

[0027] The screw nut mechanism is a servo motor control program, which is controlled by Mitsubishi FX series PLC. The acceleration time, deceleration time, base speed and other parameters are set through special registers. The push rod 21 is pushed forward by triggering the X0 port through the wireless remote control, and the push rod 21 is retreated and reset by triggering X1 through the wireless remote control. At the same time, limit switches are installed. By triggering X5 and X6, the extreme position of the push rod 21 is guaranteed to avoid the risk of collision caused by excessive movement. The contactor is controlled by the wireless remote control to realize the electric lifting control of the battery.

[0028] When the battery rapid entry device of the present invention is used, the battery is placed on the "J"-shaped profile 22 of the support platform 2, and the battery is raised and lowered to a suitable height along with the support platform 2. The battery is pushed toward the battery compartment along the pushing direction by the push rod 21 under the action of the pushing mechanism, and the vertical plate 23 on the support platform 2 constrains the moving stroke of the battery. When the support platform 2 is not directly facing the battery compartment or the direction is not directly facing the battery compartment, the battery contacts the battery compartment wall during the pushing process and is blocked by the compartment wall and deflected relative to the original pushing direction, the push rod 21 deflects accordingly with the change in the battery posture, the push rod 21 is always in contact with the battery surface, the battery slips relative to the center of the push rod 21, and the force application point of the push rod 21 on the battery moves in the deflection direction to ensure that the battery is effectively and quickly pushed into place.

[0029] Through the above description of the specific embodiment 1 of the battery rapid entry device of the present invention, it can be seen that the battery rapid entry device of the present invention solves the problem that manual assisted propulsion is easy to be misplaced and it is difficult to accurately fine-tune the battery status by arranging a propulsion mechanism on the supporting platform. The propulsion mechanism has a propulsion member for deflecting along with the change of the battery posture to push the battery into the battery compartment, thereby saving labor intensity.

[0032] For example, in other implementations, different from the above-mentioned embodiment 1, the side panels on both sides of the support platform are higher than the "J"-shaped profile, the side panels constitute a restraining structure, and no vertical panels are provided on the "J"-shaped profile.
