[0031] In addition, if terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0032] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0033] The following will introduce in detail the specific structure of a lifting tool provided by the embodiments of the present invention in combination with the patent drawings and the corresponding technical effects brought thereby.

[0034] Please refer to Figures 1 - 3 , a lifting tool 1 provided by an embodiment of the present invention includes an upper tooling 100 and a lower tooling 200. The upper tooling 100 is used to connect with a lifting device. The lower tooling 200 is connected to the lower tooling 200 and arranged at intervals in a first direction. The lower tooling 200 is provided with a grasping member 220, and the grasping member 220 is used to grasp a structure to be grasped. A power member 300 is installed on the lower tooling 200, and the power member 300 is used to apply a force in a preset direction to the outer wall of the lower tooling 200 to ensure that the lower tooling 200 is in a balanced state during the hoisting process. The first direction forms an angle with the preset direction.

[0035] It should be noted that when the lifting tool 1 is hoisted by a lifting device and the structure to be grasped is grasped by the grasping member 220, the first direction is the height direction, and the upper tooling 100 is located above the lower tooling 200. When the lifting tool 1 in this embodiment is applied to a battery swapping station, the structure to be grasped can be a battery.

[0036] The power component 300 can apply a force in a preset direction to the outer wall of the lower tooling 200. Therefore, when the spreader 1 swings due to inertial force or wind force after being lifted by the lifting equipment and during the transfer process, the power component 300 can be activated to counteract the inertial force or wind force, so as to reduce the swing amplitude until the spreader 1 is stably transported along a preset path during the transfer process, ensuring that the grabbed battery is accurately placed at the designated position.

[0037] It should be noted that in this embodiment, the preset direction is perpendicular to the first direction, that is to say, the preset direction is parallel to the horizontal plane.

[0038] In some other embodiments, the preset direction may not be perpendicular to the first direction.

[0039] Specifically, in this embodiment, the power component 300 includes a driving component and a blade 320 connected to each other. The driving component is used to drive the blade 320 to rotate. The blade 320 is installed on the outer peripheral wall of the lower tooling 200, and the rotation axis of the blade 320 is perpendicular to the outer peripheral wall of the lower tooling 200. Specifically, the driving component of the power component 300 is installed on the lower tooling 200, and the blade 320 can be understood as a propeller blade 320. During the rotation of the blade 320, a force in a preset direction can be applied to the lower tooling 200.

[0040] It should be noted that in this embodiment, the drive shaft 310 of the driving component extends out of the outer peripheral wall of the lower tooling 200 and is connected to the blade 320 to drive the blade 320 to rotate.

[0041] The lower tooling 200 includes a first installation platform 210. The first installation platform 210 has a first side wall 211 and a second side wall 212 arranged at intervals in the second direction. The first side wall 211 and the second side wall 212 are both installed with the power component 300, and the second direction is perpendicular to the first direction.

[0042] Specifically, the above-mentioned grasping component 220 is installed on the side of the first installation platform 210 away from the upper tooling 100.

[0043] It can be understood that since the first side wall 211 and the second side wall 212 are both installed with the power component 300, and the preset direction is perpendicular to the first direction, therefore, when the blades 320 on the first side wall 211 and the blades 320 on the second side wall 212 rotate, they can change the movement trajectory of the first installation platform 210 in the horizontal direction. Therefore, the influence of inertial force or wind force that appears during the process of the spreader 1 being driven by the lifting equipment can be offset by the blades 320 on the first side wall 211 and the blades 320 on the second side wall 212, so as to reduce the swing of the spreader 1 during the transfer process and ensure that the grabbed battery can be accurately placed at the designated position.

[0044] That is to say, the rotation axis of the blade 320 is perpendicular to the outer peripheral wall of the first mounting platform 210. It can be understood that in this embodiment, the rotation axis of the blade 320 on the first side wall 211 is perpendicular to the first side wall 211, and the rotation axis of the blade 320 on the second side wall 212 is perpendicular to the second side wall 212.

[0045] The first side wall 211 is provided with a plurality of power components 300 arranged at intervals in the third direction, and the second side wall 212 is provided with a plurality of power components 300 arranged at intervals in the third direction. The first direction is perpendicular to the third direction, and the third direction forms an angle with the second direction. In this embodiment, the first direction, the second direction, and the third direction are perpendicular to each other pairwise. Among them, both the first side wall 211 and the second side wall 212 extend along the third direction.

[0046] In this embodiment, the plurality of power components 300 on the first side wall 211 are arranged in one-to-one correspondence with the plurality of power components 300 on the second side wall 212. That is to say, the plurality of blades 320 on the first side wall 211 are arranged in one-to-one correspondence with the plurality of blades 320 on the second side wall 212. It can be understood that the connection line between one blade 320 on the first side wall 211 and the corresponding blade 320 on the second side wall 212 is parallel to the second direction.

[0047] Therefore, through the power components 300 on the first side wall 211 and the power components 300 on the second side wall 212, the attitude of the lower tooling 200 can be controlled more precisely to ensure that the grabbed battery can be accurately placed at the specified position.

[0048] Specifically, in this embodiment, the first side wall 211 is provided with two power components 300 arranged at intervals in the third direction, and the second side wall 212 is provided with two power components 300 arranged at intervals in the third direction.

[0049] It can be understood that under the action of the two power components 300 of the blade 320 arranged at intervals in the third direction on the first side wall 211 or the two power components 300 of the blade 320 arranged at intervals in the third direction on the second side wall 212, the first mounting platform 210 can be driven to move in the second direction. Furthermore, under the action of only turning on the power components 300 on the first side wall 211 or the second side wall 212, the attitude of the first mounting platform 210 in the second direction can be changed. That is to say, when only the power components 300 on the first side wall 211 or the second side wall 212 are turned on, the inertia or wind force in the second direction can be offset, thereby reducing the swing during the transfer process by the lifting tool 1.

[0050] When one power component 300 on the first side wall 211 is started and one non-corresponding power on the second side wall 212 is started, the first mounting platform 210 can be driven to rotate around a preset axis, and the preset axis is parallel to the first direction.

[0051] It can be understood that through the power components 300 on the first side wall 211 and the second side wall 212, the inertia of the spreader 1 itself or the external wind force can be effectively offset to ensure the attitude of the first installation platform 210 during transfer, so that the spreader 1 moves as smoothly as possible along the preset path when transferring the battery.

[0052] It should be noted that in this embodiment, both the first side wall 211 and the second side wall 212 are perpendicular to the second direction.

[0053] Specifically, for the two power components 300 on the first side wall 211, the two power components 300 are respectively close to both ends of the first side wall 211 in the third direction. For the two power components 300 on the second side wall 212, the two power components 300 are respectively close to both ends of the second side wall 212 in the third direction. It can be understood that since the two power components 300 on the first side wall 211 are respectively located at both ends of the first side wall 211, when any one of the power components is started, it is convenient to drive the first installation platform 210 to rotate along the preset axis. Similarly, since the two power components 300 on the second side wall 212 are respectively located at both ends of the second side wall 212, when any one of the power components is started, it is convenient to drive the first installation platform 210 to rotate along the preset axis.

[0054] The first installation platform 210 further includes a third side wall 213 and a fourth side wall 214 arranged at intervals in the third direction. Specifically, in this embodiment, the third side wall 213, the first side wall 211, the fourth side wall 214 and the second side wall 212 are sequentially connected end to end, that is, the first installation platform 210 is generally in the shape of a cuboid.

[0055] Optionally, at least one of the third side wall 213 and the fourth side wall 214 is provided with a power component 300. The third direction forms an angle with the second direction and is perpendicular to the first direction.

[0056] In this embodiment, the lower tooling 200 is further equipped with a camera 400 for detecting the relative position between the lower tooling 200 and the external environment to assist the spreader 1 in positioning during the transfer process. Specifically, the camera 400 is installed on the first installation platform 210.

[0057] The lower tooling 200 is further installed with an angular velocity gyroscope 500 and a controller 600. The controller 600 is communicatively connected to the angular velocity gyroscope 500, the camera 400 and the power component 300. It can be understood that the controller 600 can obtain the signals acquired by the angular velocity gyroscope 500 and the camera 400 and then control the power component 300 to achieve the smooth transfer of the spreader 1.

[0058] In this embodiment, the upper tooling 100 includes a second mounting platform 110. The second mounting platform 110 is located above the first mounting platform 210. The spreader 1 further includes a plurality of connecting members 700. The connecting members 700 are connected to both the lower tooling 200 and the second mounting platform 110, that is, the connecting members 700 are connected to both the first mounting platform 210 and the second mounting platform 110.

[0059] The connecting member 700 can adjust the distance between the second mounting platform 110 and the lower tooling 200 in the first direction. It can be understood that in this embodiment, the connecting member 700 includes a winding machine 710 and a connecting rope 720 which are connected to each other. The winding machine 710 is installed on the first mounting platform 210. The connecting rope 720 is wound around the winding machine 710. One end of the connecting rope 720 is connected to the second mounting platform 110. The winding machine 710 can control the telescopic amount of the connecting rope 720, that is, the connecting member 700 can adjust the distance between the second mounting platform 110 and the first mounting platform 210 in the first direction by controlling the telescopic amount of the connecting rope 720.

[0060] To facilitate the rotation of the spreader 1 when it is transported by the lifting equipment, a rotating hook 120 is further provided at one end of the second mounting platform 110 away from the lower tooling 200. The rotating hook 120 is used to connect with the lifting equipment.

[0061] In summary, a spreader 1 provided by an embodiment of the present invention includes an upper tooling 100 and a lower tooling 200. The upper tooling 100 is used to connect with the lifting equipment. The lower tooling 200 is connected to the lower tooling 200 and arranged at intervals along the first direction. The lower tooling 200 is provided with a grasping member 220. The grasping member 220 is used to grasp the structure to be grasped. A power member 300 is installed on the lower tooling 200. The power member 300 is used to apply a force along a preset direction to the outer wall of the lower tooling 200 to ensure that the lower tooling 200 is in a balanced state during the hoisting process. Therefore, when the spreader 1 swings due to inertial force or wind force after being lifted by the lifting equipment and during the transportation process, the power member 300 can be started to offset the inertial force or wind force to reduce the swing amplitude until the spreader 1 is stably transported along the preset path during the transportation process to ensure that the grasped battery is accurately placed at the designated position.

[0062] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
