It should be noted that the second linear driving member 300 is indirectly connected to the frame 100 through the first push rod 310 and the second push rod 320, and since the first push rod 310 and the second push rod 320 can rotate relative to the frame 100, the body of the second linear driving member 300 can float back and forth relative to the frame 100.

In this embodiment, the second linear driving member 300 is a cylinder, which has the advantages of large load, high torque output, fast action, fast response, good adaptability to working environment, etc.

It can be understood that, in this embodiment, when the output shaft of the second linear driving component 300 extends, the rear end of the first push rod 310 and the rear end of the second push rod 320 are away from each other, the first push rod 310 and the second push rod 320 respectively drive the two first positioning plates 400 to rotate, and under the action of the linkage component, the two second positioning plates 500 are driven to rotate, so that the two first positioning plates 400 and the two second positioning plates 500 all rotate to the positions extending along the front-back direction, and the two spreaders 600 entering the hoisting station are positioned.

And when the output shaft of the second linear driving part 300 shortens, the rear end of the second push rod 320 and the rear end of the first push rod 310 are close to each other, the first push rod 310 and the second push rod 320 respectively drive the two first positioning plates 400 to rotate, and drive the two second positioning plates 500 to rotate under the action of the linkage part, the two groups of first positioning plates 400 and the two groups of second positioning plates 500 respectively rotate in the opposite directions, the hanger 600 of the lifting station is loosened, and the hanger 600 can leave the lifting station from the left end or the right end of the rack 100.

When the output shaft of the second linear driving part 300 is shortened, the rear end of the second push rod 320 and the rear end of the first push rod 310 are close to each other, the first push rod 310 and the second push rod 320 respectively drive the two first positioning plates 400 to rotate, and under the action of the linkage part, the two second positioning plates 500 are driven to rotate, so that the two first positioning plates 400 and the two second positioning plates 500 are both rotated to the positions extending along the front-back direction, and the two lifting appliances 600 entering the lifting station are positioned.

And when the output shaft of the second linear driving part 300 extends, the rear end of the first push rod 310 and the rear end of the second push rod 320 are away from each other, the first push rod 310 and the second push rod 320 respectively drive the two first positioning plates 400 to rotate, and under the action of the linkage part, the two second positioning plates 500 are driven to rotate, the two groups of first positioning plates 400 and the two groups of second positioning plates 500 respectively rotate in the opposite directions, the lifting tool 600 of the lifting station is loosened, and the lifting tool 600 can leave the lifting station from the left end or the right end of the rack 100.

In the present embodiment, the second linear driving member 300 and the first push rod 310 and the second linear driving member 300 and the second push rod 320 are connected by a joint bearing, respectively. The joint bearing can bear larger load, has good shock resistance, and has the characteristics of corrosion resistance, wear resistance, self-aligning and good lubrication.

In some embodiments, each set of first positioning assemblies further includes a limiting rod 120 and a limiting block 130 for limiting the rotation angle of the first positioning plate 400 and the rotation angle of the second positioning plate 500.

Specifically, the limiting rod 120 is mounted on the frame 100, and the limiting rod 120 is disposed between the first positioning plate 400 and the second positioning plate 500 of the set of first positioning assemblies and extends in the left-right direction.

When the first positioning plate 400 and the second positioning plate 500 rotate to positions extending in the front-rear direction, the stopper rod 120 can restrict the first positioning plate 400 and the second positioning plate 500 from continuing to rotate toward each other.

The limiting block 130 is installed on the rack 100, and is located at the same side of the rack 100 as the rotating end of the first positioning plate 400, and the limiting block 130 is provided with an inclined surface which is arranged towards the limiting rod 120.

In this embodiment, the limiting rod 120 is provided with a butting surface, the butting surface is disposed towards one side of the second positioning plate 500, the limiting block 130 is located on one side of the second positioning plate 500 away from the first positioning plate 400, and the second positioning plate 500 can rotate at an angle defined by the limiting block 130 and the limiting rod 120 together.

It can be understood that, since the first positioning plate 400 and the second positioning plate 500 are linked, the rotation angle of one of the first positioning plate 400 and the second positioning plate 500 can be limited, and the rotation angle of the other can be limited.

Of course, the abutting surfaces may be disposed on the left and right sides of the limiting rod 120, and the limiting blocks 130 may be disposed on two sides, respectively, to limit the rotation angles of the first positioning plate 400 and the second positioning plate 500.

One of the second positioning plates 500 can rotate to the position abutting against the limiting rod 120, so that the first positioning plate 400 and the second positioning plate 500 of the group can not rotate in opposite directions.

And the output shaft of the second linear driving member 300 can move continuously, so as to push the first positioning plate 400 and the second positioning plate 500 of the other set of first positioning assembly to rotate continuously in opposite directions until the other second positioning plate 500 rotates to the position abutting against the limiting rod 120. At this moment, the lifting tools 600 located at the two lifting stations are respectively clamped by the two groups of first positioning plates 400 and the second positioning plates 500 and cannot leave the lifting stations, so that automatic lifting can be stably carried out at a preset position.

When the second linear driving part 300 drives the two sets of the first positioning plates 400 and the second positioning plates 500 to rotate back to back, respectively, one of the second positioning plates 500 can rotate to the position abutting against the inclined surface first and no longer rotate.

And the output shaft of the second linear driving part 300 can move continuously, so as to push the first positioning plate 400 and the second positioning plate 500 of another set of first positioning assemblies to rotate back to back continuously until another second positioning plate 500 rotates to the position abutting against the limiting block 130. At this time, the spreader 600 located at the two hoisting stations can move left and right and leave the automatic positioning mechanism.

It can be understood that, although two sets of first positioning assemblies have difference to the positioning time of the lifting appliance 600, the time difference is very short, generally not more than 1 second, and will not affect the actual lifting operation, that is, after the lifting appliance 600 of one of the lifting stations is positioned, no long-time waiting is needed, the lifting appliance 600 of the other lifting station can also be positioned, and after the lifting operation is completed, after one of the first positioning assemblies loosens the lifting appliance 600, no long-time waiting is needed, the lifting appliance 600 can also be completely loosened by the other first positioning assembly, and the two lifting appliances 600 leave the automatic positioning mechanism.

In this embodiment, the second linear driving member 300 is a cylinder with a magnetic ring, and is switched by a solenoid valve. After the detection assembly senses that the lifting appliance 600 enters the lifting station, the controller controls the electromagnetic valve to be opened, so that the second linear driving component 300 is started.

It can be understood that the controller may be a single chip, a PLC controller, etc., and may implement a simple function of controlling the start and stop of the second linear driving part 300.
