These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0021] Embodiment 1:

[0022] As Figure 1 is a schematic structural diagram of the present utility model. A port crane anchoring device includes an anchoring mechanism 1, the anchoring mechanism 1 is installed on the frame 2 of the crane, a roller 21 is installed on the frame 2 of the crane, the anchoring mechanism 1 includes a control member 11, a connecting seat 12, a main support foot 13 and an auxiliary support assembly 14. The control member 11 is threadedly connected to the frame 2. The control member 11 has a rod-shaped structure and has an external thread on it, and the frame 2 has an internal threaded hole matching the external thread on the control member 11. The connecting seat 12 is installed at the bottom end of the control member 11. A fixed connection (such as welding, bolt fixation, etc.) and a rotational connection can be adopted between the connecting seat 12 and the control member 11. The main connecting rod 15 is installed on the main support foot 13, and the main connecting rod 15 is slidably connected to the connecting seat 12. Through the design of the control member 11, the connecting seat 12, the main connecting rod 15, the main support foot 13 and the auxiliary support assembly 14, the crane can be moved to any position for anchoring, and there is no need to set an anchoring pit, which improves the use range of the equipment. And through the design of the auxiliary support assembly 14, the stress in the moving direction of the lifting mechanism can be eliminated, and the anchoring effect is improved;

[0023] As Figure 2 、 Figure 3As shown, the auxiliary support assembly 14 includes an auxiliary support foot 141, an auxiliary connecting rod 142, a sliding sleeve 143, and a transmission rod 144. The tail end of the auxiliary connecting rod 142 is rotatably connected to the auxiliary support foot 141, and the head end of the auxiliary connecting rod 142 is rotatably connected to the outer wall surface of the connecting seat 12. The sliding sleeve 143 is slidably sleeved on the auxiliary connecting rod 142. One end of the transmission rod 144 is rotatably connected to the sliding sleeve 143, and the other end is rotatably connected to the main connecting rod 15. Under the action of gravity, due to its center of gravity, the support surface of the auxiliary support foot 141 faces the ground, and after contacting the ground, the support surface of the auxiliary support foot 141 fits the ground.

[0024] As Figure 2 , Figure 3 shown, a sliding cavity 121 is formed in the connecting seat 12 for accommodating the main connecting rod 15. The head end of the main connecting rod 15 extends into the sliding cavity 121 and is slidably connected to the connecting seat 12. After the main connecting rod 15 retracts into the sliding cavity 121, the auxiliary support foot 141 can contact the ground.

[0025] As Figure 2 , Figure 3 shown, a limiting block 16 is installed on the head end of the main connecting rod 15. The limiting block 16 is located in the sliding cavity 121, and the outer wall surface of the limiting block 16 fits the inner wall of the sliding cavity 121, and the limiting block 16 is in sliding contact with the sliding cavity 121;

[0026] A through hole 122 for the main connecting rod 15 to pass through is formed in the connecting seat 12. The through hole 122 matches the main connecting rod 15. The diameter of the through hole 122 is smaller than the diameter of the sliding cavity 121. The through hole 122 is communicated with the sliding cavity 121. Through the cooperation of the limiting block 16 and the through hole 122, the limiting function is realized, and the main connecting rod 15 can be prevented from detaching from the connecting seat 12.

[0027] As Figure 3 shown, the anchoring mechanism 1 includes an elastic element 17. The elastic element 17 is located in the sliding cavity 121. One end of the elastic element 17 abuts against the connecting seat 12, and the other end abuts against the main connecting rod 15, which can provide the functions of stress elimination and shock absorption for the anchoring of the crane, thereby improving the anchoring effect.

[0028] The anchoring mechanism 1 includes a holding rod 18. The control member 11 has a connecting hole for the holding rod 18 to pass through. The holding rod 18 is located in the connecting hole of the control member 11, and the holding rod 18 is slidably connected to the control member 11, which is convenient for applying force to rotate the control member 11.

[0029] Bolts 181 are installed at both ends of the holding rod 18, which can prevent the holding rod 18 from falling off.

[0030] In the initial state, the main support feet 13 and the auxiliary support feet 141 are away from the ground. At this time, the rollers 21 are in contact with the ground, and the crane can move with the assistance of the rollers 21.

[0031] In the anchoring state, rotate the control member 11 to make the main support feet 13 approach the ground until the main support feet 13 contact the bottom surface, and then continue to rotate the control member 11 in the same direction to retract the main connecting rod 15 into the sliding cavity 121. At this time, the auxiliary support feet 141 approach the ground until the auxiliary support feet 141 contact the ground. During the descent of the auxiliary support feet 141, due to the support of the transmission rod 144, the auxiliary support feet 141 can be made to move away from the main support feet 13, so that an angle is formed between the auxiliary support feet 141 and the main support feet 13, thus better forming a support anchor.

[0032] Embodiment 2:

[0033] The distinguishing technical feature between Embodiment 2 and Embodiment 1 lies in: the connection manner between the control member 11 and the connection seat 12.

[0034] The control member 11 is rotatably connected to the connection seat 12, which can prevent the auxiliary support assembly 14 from rotating synchronously with the control member 11, so that the support position thereof changes and the support effect is altered.

[0035] Embodiment 3:

[0036] There are two auxiliary support assemblies 14. The auxiliary support assemblies 14 are located on the left and right sides of the connection seat 12, and one of the auxiliary support assemblies 14 is located between the connection seat 12 and the rollers 21. The auxiliary support assemblies 14 in this application may also have three or more, and the auxiliary support assemblies 14 are distributed at intervals along the circumferential direction of the connection seat 12.
