In some embodiments, as shown in connection with fig. 6 and 7, second locking device 400 includes a latch 410 and a lock release assembly 420, wherein latch 410 is rotatably coupled to slewing bearing device 200 in a mating manner, and lock release assembly 420 is fixedly mounted to slewing bearing device 200. The latch 410 is controllably rotatable about a direction parallel to the radial direction of the slewing bearing device 200 to enable the second locking device 400 to lock the tray 70 or release the tray 70. The locking release assembly 420 preferably has two locking members symmetrically installed at both sides of the locking buckle 410 in the direction parallel to the radial direction of the pivoting support device 200, for being capable of simultaneously abutting against both sides of the locking buckle 410, respectively, when the locking buckle 410 locks the tray 70, so that the locking buckle 410 firmly locks the tray 70, thereby enabling the second locking device 400 to lock the tray 70, or simultaneously disengaging the locking buckle 410, so that the locking buckle 410 can release the tray 70, thereby enabling the second locking device 400 to release the tray 70.

Further, as shown in fig. 6 and 7, each lock release assembly 420 may further include a first elastic element 423, where the first elastic element 423 may be a spring, specifically, the first elastic element 423 is sleeved on the movable portion 422, and one end of the first elastic element 423 is fixedly connected to the fixed portion 421, and the other end is fixedly connected to an end of the movable portion 422 away from the latch 410, where the first elastic element 423 is configured to provide an elastic force for making the movable portion 422 approach and abut against the latch 410. When the second locking device 400 locks the tray 70, one end of the movable portion 422 is abutted against the lock catch 410 under the action of the pre-loading force of the first elastic element 423, and at this time, the lock catch 410 cannot rotate freely relative to the slewing bearing device 200, so that the tray 70 can be locked; when one end of the movable portion 422 is connected to the latch driving device 600 and is driven by the latch driving device 600 to separate from the lock catch 410, the first elastic element 423 is stretched and deformed to be restored, and at this time, the second locking device 400 is in a released state, and the lock catch 410 can rotate freely relative to the slewing bearing device 200. When the latch driving device 600 is disengaged from one end of the movable portion 422, the movable portion 422 is in a free state, and at this time, the movable portion 422 can drive the movable portion 422 to move toward the direction approaching the lock catch 410 under the action of the elastic force of the first elastic element 423, and one end of the movable portion 422 can be abutted against the lock catch 410 again, so that the lock catch 410 cannot rotate relative to the slewing bearing device 200, and the second locking device 400 can be in a state of locking the tray 70 again.
As shown in fig. 6, the tray 70 includes a tray body 710, a loading portion 720 and a connecting portion 730, the tray body 710 is in a cylindrical structure, the loading portion 720 and the connecting portion 730 are sleeved on the outer peripheral surface of the tray body 710 along the axial direction of the tray body 710 at intervals, the loading portion 720 is used for installing circumferential reinforcing steel bars, and the connecting portion 730 is used for being connected with the slewing bearing device 200.
Thus, as shown in fig. 6 and 9, when the tray 70 is coaxially mounted on the slewing bearing device 200, the lock catch 410 can rotate around the radial direction parallel to the slewing bearing device 200, so that one end of the lock catch 410 approaches the slewing bearing device 200, at this time, the lock catch 410 abuts against the surface of the connecting portion 730 of the tray 70, which is far away from the slewing bearing device 200, and a space for locking the tray 700 is formed between the lock catch 410 and the slewing bearing device 200, so that the second locking device 400 locks the tray 700, and the tray 70 is fixed on the slewing bearing device 200 and cannot move relative to the slewing bearing device 200; correspondingly, the lock catch 410 can reversely rotate around the radial direction parallel to the slewing bearing device 200, so that one end of the lock catch 410 is far away from the slewing bearing device 200, and at the moment, the lock catch 410 is separated from the tray 70, so that the second locking device 400 releases the tray 70, and the tray 70 can move relative to the slewing bearing device 200 and can be lifted by the crane.
With continued reference to fig. 7, in some embodiments, two sides of the latch 410 along a direction parallel to the radial direction of the slewing bearing device 200 are respectively provided with a concave limiting slot 411, and the shape and size of the limiting slot 411 are matched with those of one end of the movable portion 422 of the locking release assembly 420 for supporting the latch 410, so that the movable portions 422 of the two locking release assemblies 420 can be more firmly supported on two opposite sides of the latch 410 respectively.
Further, in some embodiments, the second locking device 400 further includes a second elastic element 430, and the second elastic element 430 may also be a spring. One end of the second elastic element 430 is fixedly connected to the body 210 of the slewing bearing, and the other end is fixedly connected to the latch 410, and the second elastic element 430 is configured to provide an elastic force for reversely rotating the latch 410 and releasing the tray 70. When the lock catch 410 rotates to lock the tray 70 so that the second locking device 400 locks the tray 70, the second elastic element 430 can stretch to generate recoverable deformation; when the two locking release assemblies 420 are simultaneously disengaged from the lock catch 410, the lock catch 410 can drive the lock catch 410 to reversely rotate under the elastic force of the second elastic element 430, so that the second locking device 400 releases the tray 70.
With continued reference to fig. 6 and 9, in some embodiments, the biasing apparatus 500 includes a second mount 510, a third drive assembly 520, and a ram assembly 530. The second fixing base 510 is fixedly installed on the base 100, and the second fixing base 510 has a first sliding rail 511 for supporting the ram assembly 530, so that the ram assembly 530 can slide smoothly along the first sliding rail 511.

The ram assembly 530 includes a ram slider 531 and a ram 532, where the ram slider 531 is mounted at an end of the third driving assembly output 522 remote from the third driving assembly fixing portion 521, and the ram 532 is fixedly mounted on the ram slider 531, so that the ram slider 531 can drive the ram 532 along the first sliding rail 511 along with the third driving assembly output 522 to perform a reciprocating linear motion smoothly.
In the present embodiment, the third driving component 520 is perpendicular to the lock release component 420 in the second locking device 400, so that when the third driving component output portion 522 moves away from the third driving component fixing portion 521 relative to the third driving component fixing portion 521, the pressing head 532 can move along with the third driving component moving portion 522 relative to the second fixing base 510 toward the direction approaching the lock catch 410, so that the pressing head 532 can contact the lock catch 410 and can press against the lock catch 410, and the lock catch 410 can rotate around the direction parallel to the radial direction of the slewing bearing device 200 to abut against the connecting portion of the tray 70, thereby locking the tray 70.
Thus, when the tray 70 needs to be released, the movable portion 422 of the locking and releasing component 420 in the second locking device 400 is only driven to move in a direction away from the lock catch 410, so that the movable portion 422 is separated from the lock catch 410, and the lock catch 410 can automatically rotate under the action of the elastic force of the second elastic element 430 to release the tray 70; when the tray 70 needs to be locked, the third driving component 520 of the pressing device 500 is only required to drive the pressing head 532 of the pressing device 500 to reversely rotate and reset to be abutted against the tray 70, and meanwhile, the movable portion 422 of the locking release component 420 automatically moves towards the direction approaching to the lock catch 410 under the action of the elastic force of the first elastic element 423 to be abutted against the lock catch 410, so that the lock catch 410 can lock the tray 70. Through the design of the structure, the aim of automatically releasing and locking the material tray 70 can be achieved by sequentially moving each part, and the degree of automation of the seam welder is improved.

The fourth driving assembly 620 and the fifth driving assembly 630 may also be motors, hydraulic cylinders, or air cylinders, etc., which are not limited herein. The first latch assembly 640 is mounted to the fourth drive assembly 620 for selective insertion into a first limiting aperture 4221 in the lock release assembly 420, and the second latch assembly 650 is mounted to the fifth drive assembly 630 for selective insertion into a second limiting aperture 4222 in the lock release assembly 420 to enable the disengagement of the movable portion 422 in the lock release assembly 420 from the latch 410 and the retention of the latch 410, respectively.
Specifically, the fourth driving unit 620 includes a fourth driving unit fixing portion 621 and a fourth driving unit output portion 622, the fourth driving unit fixing portion 621 is fixedly mounted to the third fixing base 610, and the fourth driving unit output portion 622 can reciprocate relative to the fourth driving unit fixing portion 621; similarly, the fifth driving assembly 630 includes a fifth driving assembly fixing portion 631 and a fifth driving assembly output portion 632 (the fifth driving assembly output portion 632 is not shown in fig. 9), the fifth driving assembly fixing portion 631 is also fixedly mounted to the third fixing base 610, and the fifth driving assembly output portion 632 is also capable of reciprocating relative to the fifth driving assembly fixing portion 631.

Similarly, the second latch assembly 650 has the same structure as the first latch assembly 640, and the second latch assembly 650 includes a second latch slide 651 and a second latch 652 (not shown in fig. 9), the second latch slide 651 being mounted at one end of the fifth driving assembly output 632 remote from the fifth driving assembly fixing portion 631, the second latch 652 being fixedly mounted on the second latch slide 651, such that the second latch slide 651 can smoothly reciprocate with the second latch 652 along the other second slide rail 611 of the third fixing base 610 along with the fifth driving assembly output 632. Thus, with the above arrangement, the first latch assembly 640 and the second latch assembly 650 can each be independently moved toward or away from the movable portion 422 in the lock release assembly 420 by the fourth drive assembly 620 and the fifth drive assembly 630, respectively.
In some embodiments, as shown in fig. 8, the first latch 642 is an elongated plate-shaped structure having a thickness, the thickness direction of which is consistent with the axial direction of the slewing bearing device 200, both sides of the first latch 642 along the thickness direction are planar, and one end of the first latch 642 near the lock release assembly 420 has a first inclined surface 6421 and a second inclined surface 6422 intersecting with each other, and the distance between the first inclined surface 6421 and the second inclined surface 6422 gradually decreases from the fourth driving assembly fixing portion 621 toward the fourth driving assembly output portion 622. The second latch 652 is identical in construction to the first latch 642, having intersecting third and fourth inclined surfaces 6521, 6522 at one end adjacent the lock release assembly 420, and a distance between the third and fourth inclined surfaces 6521, 6522 gradually decreases from the fifth drive assembly securing portion 631 toward the fifth drive assembly output 632.

Referring to fig. 1 to 9, the above positioning and locking mechanism 10 has the following operation procedures:
first, as shown in fig. 1, 3 and 5, the slewing bearing device 200 is rotated to an initial position, and the second driving assembly 320 in the first locking device 300 is started, so that the second driving assembly 320 drives the positioning pin 330 to be limited in the origin positioning slot 241 of the slewing bearing device 200, thereby fixing the slewing bearing device 200 in the initial position and preventing the slewing bearing device from rotating relative to the stand 100.

At this time, the fourth driving component 620 of the latch driving device 600 is started, so that the fourth driving component 620 drives the first latch 642 to be inserted into the first limiting hole 4221 of the lock release component 420, and drives the movable portion 422 of the lock release component 420 to move in a direction away from the lock catch 410, so that the movable portion 422 is separated from the lock catch 410, and the lock catch 410 rotates around a direction parallel to the radial direction of the slewing bearing device 200 under the action of the second elastic element 430, so that one end of the lock catch 410 is away from the fixed bearing device, and the second locking device 400 is in a release state, and meanwhile, the first elastic element 423 is compressed to generate recoverable deformation.
In the third step, as shown in fig. 1 to 3, the tray 70 to be replaced is lifted away, and the tray 70 to be mounted on the slewing bearing device 200 is placed and mounted on the slewing bearing device 200 through the lugs 220 of the slewing bearing device 200, the tray positioning block 230 and the third fixing seat 610510 of the second locking device 400.
In a fourth step, as shown in fig. 6, 7, 8 and 9, the third driving unit 520 of the pressing device 500 is activated, so that the third driving unit 520 drives the pressing head 532 to move in a direction approaching the lock catch 410, the pressing head 532 contacts the lock catch 410, and is further capable of pressing against the lock catch 410, so that the lock catch 410 can rotate around a direction parallel to the radial direction of the slewing bearing device 200, at this time, the lock catch 410 abuts against a side surface of the loading portion 720 of the tray 70, which is far away from the slewing bearing device 200, and at the same time, the fourth driving unit 620 is driven again, the first latch 642 of the latch driving device 600 moves reversely in a direction approaching the fourth driving unit 620 to the outside of the first limiting hole 4221, so that the movable portion 422 of the lock release assembly 420 is in a free state, at this time, the movable portion 422 moves in a direction approaching the lock catch 410 under the elastic force of the first elastic element 423, so that one end of the movable portion 422 abuts against the lock catch 410, so that the second locking device 400 remains locked, and the tray 70 is fixed on the slewing bearing device 200, and cannot move relative to the slewing bearing device 200.
In the fifth step, in order to further ensure that the movable portion 422 can firmly abut against the lock catch 410, the fifth driving component 630 of the latch driving device 600 is started, so that the fifth driving component 630 drives the second latch 652 to be inserted into the second limiting hole 4222 of the lock release component 420, and drives the movable portion 422 of the lock release component 420 to move further towards the direction close to the lock catch 410, so that one end of the movable portion 422 can further abut against the lock catch 410, and the condition that the movable portion 422 of the lock release component 420 cannot abut against the lock catch 410 in place is prevented, so that the lock catch 410 can be ensured to firmly lock the tray 70. Thus, the entire operation flow of the positioning and locking mechanism 10 is completed.
It should be noted that, when the movable portion 422 of the lock release assembly 420 is already firmly held against the latch 410 in the fourth step, the fifth step may not be performed. When the dimensions of the tray 70 and the slewing bearing device 200, or the length of the origin positioning block 240 are changed, as shown in fig. 5, the first locking device 300 of the second embodiment may be used, and the positioning pins 330 may be positioned at the initial positions for the slewing bearing devices 200 with different dimensions by adjusting the angles of the second driving assembly 320 and the second fixing seat 510 in the first locking device 300.
