[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 4 , the utility model provides a technical solution:

[0026] The pallet positioning device includes a pallet body, four groups of lifting ears 14 are arranged around the pallet body, and the lifting ears 14 are welded to the pallet body. By setting the lifting ears 14, it is convenient to lift the pallet and the iron ingot; the pallet body includes a support frame 1, a top plate 2 is fixedly installed on the top of the support frame 1, and two groups of movable grooves 3 are symmetrically opened on the top surface of the top plate 2.

[0027] It also includes a positioning component, which includes two groups of symmetrically arranged chucks 4. The side of the chuck 4 that contacts the iron ingot is glued with a rubber pad 13, and the rubber pad is provided with an anti-slip groove. A moving seat 5 is fixedly installed at the bottom of the chuck 4. The moving seat 5 slides with the moving groove 3. The moving seats 5 at the bottom of the two groups of chucks 4 are respectively threaded with two groups of reverse thread grooves of the bidirectional screw rod 6. The two ends of the bidirectional screw rod 6 are rotationally matched with the inner walls of the two sides of the support frame 1. A card slot 10 is provided at one end of the bidirectional screw rod 6. The card slot 10 is used in conjunction with a card key 8 fixedly installed in a sleeve 9. The sleeve 9 is fixedly connected to a crank 11. By setting the bidirectional screw rod 6, the two groups of moving seats 5 and the chuck 4 can be driven to move toward each other synchronously to clamp the iron ingot and position it at the center of the top surface of the tray body to prevent the iron ingot from shifting and falling during hoisting.

[0028] The locking member 7 is also included. The locking member 7 is arranged at the other end of the bidirectional screw rod 6. The locking member 7 includes a fixed seat 701 and a locking head 702. The fixed seat 701 is fixedly connected to one end of the bidirectional screw rod 6. The locking head 702 and the inner cavity 703 opened by the fixed seat 701 have a sliding clearance. The limiting plate 704 fixedly installed at one end of the locking head 702 is slidably matched with the inner cavity 703. A through hole is opened inside the locking head 702. The locking head 702 is slidably matched with the bidirectional screw rod 6 through the through hole. The locking member 7 also includes a spring 705. The spring 705 is arranged in the inner cavity 703, and the spring 705 is slidably sleeved on the surface of the bidirectional screw rod 6. One end of the spring 705 It is fixedly connected to the inner wall of the inner cavity 703, and the other end of the spring 705 abuts against the limit plate 704. The limit plate 704 can prevent the locking head 702 from being separated from the fixing seat 701; a locking groove 12 is provided in the middle of one side of the support frame 1, and the locking groove 12 is slidably matched with the locking head 702. By setting the locking groove 12 and using it in conjunction with the locking head 702, when the sleeve 9 is inserted into the locking groove 12, the locking head 702 is pushed to separate from the locking groove 12 at the same time, and the bidirectional screw rod 6 is unlocked; and when the sleeve 9 is pulled out, after aligning the locking head 702 and the locking groove 12, the locking groove 12 automatically pops out and is inserted into the locking groove 12 to lock the bidirectional screw rod 6.

[0029] When in use, the device is moved to a designated position, the iron ingot is placed in the middle of the tray body, the crank handle 11 is moved, the sleeve 9 is aligned with the locking groove 12, and the card slot 10 and the card connection key 8 are aligned, the sleeve 9 is inserted into the locking groove 12, and at the same time, the sleeve 9 pushes the locking head 702 to move inside the fixed seat 701, so that the locking head 702 is disengaged from the locking groove 12, and the crank handle 11 is shaken to rotate the sleeve 9, and the sleeve 9 drives the bidirectional screw rod 6 to rotate through the card slot 10 and the card connection key 8, respectively cooperating with the two sets of reverse thread grooves of the bidirectional screw rod 6. The moving seat 5 drives the two groups of chucks 4 to start moving towards each other until the rubber pad 13 on one side of the chuck 4 contacts the surface of the iron ingot and clamps it in the center of the tray body. By slightly turning the handle and the sleeve 9, the locking head 702 is rotated and aligned with the locking groove 12, and the crank 11 and the sleeve 9 are pulled out. After the locking head 702 loses the resistance of the sleeve 9, the compressed spring 705 pushes the limit plate 704 and the locking head 702 to pop out, and the locking head 702 is stuck in the locking groove 12, locking the position of the bidirectional screw rod 6, thereby locking the position of the chuck 4.
