The base includes two brackets 110, which are spaced apart from each other. The hook box body 120 is rotatably arranged between the two brackets 110, so that the hook box body 120 can rotate to adjust the position and attitude of the hook box when the hook 230 enters and exits the hook box. The hook box 100 for the hook 230 can be fixed to equipment such as a wind power installation platform and a heavy lift ship through the brackets 110. At least one bracket 110 is provided with a plurality of position adjustment holes 111, and the plurality of position adjustment holes 111 are spaced along the rotation direction of the hook box body 120. Elastic members 140 are provided in the plurality of position adjustment holes 111. The hook box body 120 is provided with insertion holes. During the rotation of the hook box body 120, the insertion holes can be sequentially aligned with each position adjustment hole 111. When the insertion holes and the position adjustment holes 111 are aligned, the limit pins 130 can be inserted into the insertion holes. The new type of hook box 100 for the hook 230 further includes a plurality of limit pins 130, and the plurality of limit pins 130 are correspondingly inserted into the plurality of position adjustment holes 111. The limit pins 130 cooperate with the elastic members 140, and the elastic members 140 provide an elastic force for the limit pins 130 to move in the direction towards the hook box body 120. The limit pins 130 are movably arranged to switch between an avoidance state and a rotation stopping state, and the normal state of the limit pins 130 is the avoidance state. In the rotation stopping state, the limit pins 130 form an elastic contact between the driving member of the elastic member 140 and the hook box body 120 and extend into the insertion holes when passing through the insertion holes. When the limit pins 130 are inserted into the insertion holes, the position limit of the hook box body 120 is realized, and at this time, the hook box body 120 cannot rotate. In the avoidance state, there is a distance between the limit pins 130 and the hook box body 120 to avoid the limit pins 130 interfering with the rotation of the hook box body 120.

[0026] In this embodiment, on the one hand, by rotatably arranging the hook box body 120 relative to the base, the hook box body 120 can rotate to adjust the position and attitude of the hook box when the hook 230 enters and exits the hook box, reducing the difficulty of the hook 230 entering and exiting the hook box, and further reducing the operation difficulty of the crane when the hook 230 enters and exits the hook box; on the other hand, by arranging an elastic member 140 and a limit pin 130 in each position adjustment hole 111, the limit pin 130 cooperates with the elastic member 140 and the elastic member 140 provides an elastic force for the limit pin 130 to move towards the hook box body 120, and the limit pin 130 can switch between an avoidance state and a rotation stop state. When the limit pin 130 is in the avoidance state, there is a distance between it and the hook box body 120 to avoid interfering with the rotation of the hook box body 120. When the limit pin 130 is in the rotation stop state, it is elastically in contact with the hook box body 120 and extends into the jack when passing through the jack. There is no need for the staff to observe and determine whether the jack and the position adjustment hole 111 are aligned and then manually insert the limit pin 130 into the jack, making the operation of fixing the position of the hook box body 120 simple and convenient, and reducing the work burden of the operator.

[0027] Among them, Figure 2 the limit pin 130 is not shown.

[0030] Release the limit of the hook box body 120 by the limit pin 130 (that is, switch the limit pin 130 to the avoidance state), and the boom 210 of the crane swings to the resting position. During this period, the hook box body 120 rotates under the drive of the hook 230 and is in an inclined state;

[0031] Switch the limit pin 130 in the position adjustment hole 111 closest to the jack to the rotation stop state (if the jack is located between two adjacent position adjustment holes 111, the limit pins 130 in these two position adjustment holes 111 can be switched to the rotation stop state), and then drive the hook box body 120 to rotate a small range by the rope 220 of the crane until the limit pin 130 in the rotation stop state is inserted into the jack.

[0032] The process of the hook 230 exiting the box is as follows:

[0033] Switch the limit pin 130 inserted into the jack to the avoidance state, and swing the boom 210 to make the hook box body 120 in the initial state;

[0034] One of the limit pins 130 is cut and inserted into the insertion hole to fix the hook box body 120 in the initial state, and the crane lifts the hook 230 out of the hook box body 120.
