The clamping plate 6 is moved to drive the limiting block 13 to move. The movement of the limiting block 13 is matched with the limiting groove 12 to limit the movement of the clamping plate 6, facilitating the disassembly, installation, and adjustment of the clamping plate 6.

[0030] Reference Figure 1 and Figure 2 , a reinforcing plate 14 is fixedly installed at the bottom inside the connecting plate 8. A support plate 15 is fixedly installed at the bottom of the connecting plate 8. The bottom of the support plate 15 is fixedly connected to the top of the hook 3.

[0031] As a technical optimization solution of the utility model, a reinforcement plate 14 is set at the inner bottom of the connecting plate 8, and the connecting plate 8 is connected to the reinforcement plate 14 to reinforce the connecting plate 8, and the supporting plate 15 and the hook 3 are connected through the connecting plate 8.

[0032] The working principle and use process of the utility model are as follows: when using, the hook 3 is installed so that the connecting plate 8 drives the connecting rod 53 to move through the first slide groove 51 to the inside of the second slide groove 52. The second slide groove 52 is vertically opened to facilitate the support work of the connecting rod 53. The second slide groove 52 cooperates with the connecting rod 53 to connect the connecting plate 8. The movable clamping plate 6 is installed so that the clamping plate 6 drives the limit block 13 to move. The limit block 13 moves and cooperates with the limit groove 12 to limit the movement of the clamping plate 6, which is convenient for disassembly and assembly of the clamping plate 6. The movement of the clamping plate 6 drives the positioning rod 71 to be plugged and matched with the positioning groove 72 to limit the clamping plate 6. Then, tighten the positioning bolt 73 to position the clamp plate 6, and use the clamp plate 6 to position the other end of the connecting rod 53. Install the clamp plate 6 so that the clamp plate 6 drives the baffle plate 9 to move into the first slide groove 51 to close the first slide groove 51, block the connecting rod 53 to prevent the connecting rod 53 from detaching from the second slide groove 52 when shaking, resulting in the inability to connect to the hook 3, and insert the connecting rod 53 with the other end of the connecting rod 53 through the slot 10 to position the end of the connecting rod 53 away from the second slide groove 52, reinforce the connection of the connecting plate 8 through the reinforcement plate 14, and connect the support plate 15 and the hook 3 through the connecting plate 8.

[0033] In summary, for the auxiliary connection structure for a crane hook, by providing the first chute 51, positioning rod 71 and baffle 9, the first chute 51 and the second chute 52 are opened through the mounting base 4. When installing the hook 3, the connecting plate 8 drives the connecting rod 53 to move through the first chute 51 into the second chute 52. The vertically opened second chute 52 facilitates the support work for the connecting rod 53. The second chute 52 and the connecting rod 53 cooperate to connect the connecting plate 8. When installing the clamping plate 6, the clamping plate 6 drives the positioning rod 71 to be inserted into and cooperate with the positioning groove 72 to limit the clamping plate 6. Subsequently, the positioning bolt 73 is tightened to position the clamping plate 6. The clamping plate 6 positions the other end of the connecting rod 53. When installing the clamping plate 6, the clamping plate 6 drives the baffle 9 to move into the first chute 51 to close the first chute 51 and block the connecting rod 53 to prevent the connecting rod 53 from disengaging from the second chute 52 when shaking, resulting in the inability to connect the hook 3. The other end of the connecting rod 53 away from the second chute 52 is positioned by inserting and cooperating with the slot 10. This solves the problems that many hook designs are complex or the fixing methods make the disassembly and replacement processes cumbersome. When regular inspections or repairs are required, operators may need to spend more time and labor. And when hook replacement or repair is needed, it may cause the entire crane to stop using temporarily, thus affecting the production schedule and operation efficiency.
