[0031] The present invention will be further described below with reference to the drawings. It should be noted that this embodiment is based on the present technical solution and gives detailed implementation manners and specific operation processes, but the protection scope of the present invention is not limited to this embodiment.

[0032] Embodiment 1

[0033] This embodiment provides a link-type carrier plate trolley. As Figures 1-8 shown, it includes a trolley frame 131, a traveling mechanism and a lifting mechanism;

[0034] The walking mechanism includes track wheels, drive motors, motor stabilizing seats, and motor connecting rods. On both sides of the trolley frame 131, there are at least track wheels located at the front and rear. The track wheels on one side are all flat wheels 1111, and the track wheels on the other side are all guide wheels 1112. A card slot 1113 is circumferentially arranged on the outer peripheral surface of the guide wheel 1112, and the card slot 1113 is used to engage with the track for cooperation. The front track wheels and / or rear track wheels on both sides are all drivingly connected to a drive motor 112, and each drive motor 112 is fixed to the trolley frame 131 through a motor stabilizing seat 114.

[0035] It should be noted that the card slot on the guide wheel plays a role in walking deviation correction, enabling the trolley to walk along the track without derailing. Each drive motor is used to provide the power for walking to the corresponding track wheel. The motor stabilizing seat and the motor connecting rod are used in combination. One of their functions is to eliminate the reaction force during the output of torque by the drive motor, making the drive motor stable. Another function is that during the up and down movement of the trolley lifting plate frame, the drive motor can be kept horizontal through the cooperation of the connecting rod.

[0036] In this embodiment, as Figure 8 shown, the drive motor 112 is drivingly connected to the axle 1121 of the track wheel and is fixedly connected with an anti-overturning shaft pin 1122. The motor stabilizing seat 114 is fixed to the trolley frame 131. The walking mechanism further includes a motor connecting rod 113, and both ends of the motor connecting rod 113 are rotatably connected to the motor stabilizing seat 114 and the anti-overturning shaft pin 1122 respectively.

[0037] More specifically, both ends of the motor connecting rod 113 are provided with shaft holes, and the motor stabilizing seat 114 is provided with a matching shaft hole 1141. The motor stabilizing seat 114 is connected to the shaft hole at one end of the motor connecting rod 113 by a pin through its shaft hole 1141, and the shaft hole at the other end of the motor connecting rod 113 is coaxially connected to the anti-overturning shaft pin 1122.

[0038] It should be noted that during the lifting process of the trolley frame 131, the motor stabilizing seat 114 will move up and down accordingly, affecting the level of the drive motor. By setting the motor connecting rod 113 to make a transitional connection between the motor stabilizing seat 114 and the anti-overturning shaft pin 1122, and both ends of the motor connecting rod 113 are rotatably connected, the drive motor can be prevented from rotating during the driving process of walking, and the drive motor can also be kept in a horizontal state during the lifting process.

[0039] The lifting mechanism is composed of a lifting swing arm 121, a swing arm connecting piece 126, a swing arm connecting rod 122, a connecting rod connecting seat 123, an electro-hydraulic push rod 124, and an electro-hydraulic push rod fixing seat 125; each track wheel is rotatably connected to a lifting swing arm through a rotating shaft; one end of each lifting swing arm 121 is fixedly connected to the trolley frame 131 through a fixed shaft 133 on the trolley frame 131; between the other ends of the front lifting swing arms 121 and between the other ends of the rear lifting swing arms 121 are respectively connected through a swing arm connecting piece 126; the other ends of the lifting swing arms 121 on the same side are connected through a swing arm connecting rod 122, and both ends of the swing arm connecting rod 122 are respectively rotatably connected to the corresponding lifting swing arm 121 through a connecting rod connecting seat 123; the swing arm connecting piece 126 located in the front or rear is connected to the electro-hydraulic push rod 124, and the electro-hydraulic push rod 124 can drive the swing arm connecting piece 126 to move back and forth; the electro-hydraulic push rod 124 is fixed on the trolley frame 131 through the electro-hydraulic push rod fixing seat 125.

[0040] Specifically, the lifting swing arm 121 is provided with a shaft mounting hole 1211 for connecting the wheel shaft of the corresponding track wheel, and a mounting hole 1212 for connecting the fixed shaft 133 on the trolley frame 131.

[0041] It should be noted that under the extension action of the electro-hydraulic push rod, the synchronous movement of the four lifting swing arms can be realized through the swing arm connecting piece and the swing arm connecting rod. When lowering each track wheel by using the lifting swing arm, each track wheel acts on the track, and thus the entire trolley frame can be lifted.

[0042] On both sides of the bottom of the trolley frame 131, there are respectively provided hanging plate planes 132 extending in the front-rear direction, and the hanging plate planes 132 on both sides are arranged oppositely.

[0043] Specifically, in this embodiment, the hanging plate planes on both sides are respectively in an L shape and an inverted L shape.

[0044] It should be noted that the trolley frame is the key frame connecting each component and is also a movable frame, while the hanging plate plane is the support point for lifting the electrode plate, and the shape structure of the hanging plate plane can be set according to the specific electrode plate to be transported.

[0045] Embodiment 2

[0046] This embodiment provides a method for loading plates using the link-type plate-carrying trolley described in Embodiment 1. The specific process is as follows:

[0047] As Figures 9-10As shown in the figure, tracks 2 are respectively provided on both sides of the top of the frame 3, and the bottom is supported by frame legs 4. The plate arrangement racks waiting for transfer are arranged on the frame 3; the link-type plate-carrying trolley 1 can move back and forth on the tracks 2 on both sides through the traveling mechanism 11; during movement, the driving motor is used to drive the rotation of the track wheels connected thereto, so as to realize the movement of the track wheels on the tracks.

[0048] When the link-type plate-carrying trolley 1 starts to move towards the direction of the plates, the trolley frame is in a low position state, and the hanging plate planes on both sides of its bottom correspond to the ears on both sides of the plates; after the link-type plate-carrying trolley 1 reaches the position where the plates are located, while continuing to move, the ears on both sides of each plate respectively enter the hanging plate planes on both sides of the trolley frame; after the ears of all the plates to be transferred have entered the hanging plate planes, the electro-hydraulic push rod is controlled to start. The electro-hydraulic push rod performs an extension action, and drives the other ends of each lifting swing arm to move downward through the swing arm connecting piece and the swing arm link, so that the lifting swing arm rotates around the axle of the track wheel, and one end of the lifting swing arm moves upward, and finally the trolley frame is lifted upward to a high position state. At this time, the hanging plate planes on both sides serve as the supports at both ends of the plates and also lift the plates together.

[0049] It should be noted that the frame and the tracks are both the original unit configurations. In actual application, the link-type plate-carrying trolley can be matched with the unit.

[0050] For those skilled in the art, various corresponding changes and deformations can be given according to the above technical solutions and concepts, and all these changes and deformations should be included within the protection scope of the claims of the present invention.
