[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figs. 1-3The utility model provides a technical solution: a crawler crane base with a positioning mechanism, including a crawler crane base 1 and a main body 2, a connecting seat 3 is provided in the middle of the top of the crawler crane base 1, a positioning block 4 is provided at the bottom of the main body 2, a through hole 5 is provided in the middle of the crawler crane base 1 and the connecting seat 3, a mounting block 6 is provided in the through hole 5, a positioning column 7 is provided on the top of the mounting block 6, a positioning groove 8 is provided on both sides of the positioning column 7, a mounting hole 9 is provided in the lower half of the mounting block 6, a spring 10 is provided in the mounting hole 9, a fixing rod 11 is provided at both ends of the spring 10, a through groove 12 is provided in the middle of the fixing rod 11, a positioning hole 13 is provided on the top of the mounting hole 9, a push rod 14 is provided in the positioning hole 13, and a fixing port 15 is provided on the left and right inner walls of the through hole 5. The crawler crane main body is installed, and the main body 1 is lifted and moved to the crawler The main body 1 is lifted up and gradually descends. During this process, the positioning block 4 contacts the positioning slot 8. When the bottom end of the positioning block 4 moves into the positioning slot 8, the main body 1 can be directly lowered slowly. The lower part of the positioning slot 8 cooperates with the positioning block 4. During the downward movement of the main body 1, the positioning block 4 cooperates with the positioning slot 8 to gradually correct the position of the main body 1 to ensure the rapid positioning of the main body 1 and complete the installation. When the main body 1 is about to be installed, the positioning block 4 pushes the push rod 14. The lower part of the push rod 14 is set to an inclined surface and cooperates with the inner wall of one side of the through groove 12. The push rod 14 moves downward to push the fixing rod 11 to move toward the middle of the mounting block 6. After the fixing rod 11 disengages from the fixing port 15, when the installation of the main body 1 is completed, the mounting block 6 and the connecting seat 3 fall downward under the action of gravity, and the connecting seat 3 and the mounting block 6 will not affect the rotation of the crawler crane main body.

[0016] Among them, the positioning groove 8 is gradually inclined upward from the middle to the middle of the positioning column 7, and the positioning groove 8 is gradually inclined upward from the middle to the front and rear ends of the positioning groove 8 in the front and rear directions. The upper opening size of the positioning groove 8 is larger, and the positioning block 4 is easier to install into the positioning groove 8. When the bottom of the positioning block 4 contacts the installation groove 8, there is no need to adjust the main body 1. The main body 1 is gradually moved downward, and the positioning block 4 corrects the position of the main body 1 in the gradually shrinking positioning groove 8, so that the main body 1 can be quickly installed.

[0017] The inner wall of one side of the through slot 12 is set to be inclined, and the lower side of the push rod 14 is set to an inclined surface. The positioning block 4 pushes the push rod 14 to move downward. The inclined surface set at the lower part of the push rod 14 cooperates with the inner wall of one side of the through slot 12 set to be inclined, pushing the fixing rod 11 to move.

[0018] Working principle: the main body 1 is lifted and moved to the top of the crawler crane base 1 and gradually descends. During this process, the positioning block 4 contacts the positioning slot 8. When the bottom end of the positioning block 4 moves into the positioning slot 8, the main body 1 can be directly lowered slowly. The lower part of the positioning slot 8 cooperates with the positioning block 4. During the downward movement of the main body 1, the positioning block 4 cooperates with the positioning slot 8 to gradually correct the position of the main body 1 to ensure the rapid positioning of the main body 1 and complete the installation. When the main body 1 is about to be installed, the positioning block 4 pushes the push rod 14. The lower part of the push rod 14 is set to an inclined surface and cooperates with the inner wall of one side of the through slot 12. The push rod 14 moves downward to push the fixing rod 11 to move toward the middle of the mounting block 6. After the fixing rod 11 disengages from the fixing port 15, when the installation of the main body 1 is completed, the mounting block 6 and the connecting seat 3 fall downward under the action of gravity, and the connecting seat 3 and the mounting block 6 will not affect the rotation of the crawler crane main body.
