DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figures 1 to 4 , the utility model provides a technical solution:

[0025] An anchoring device for a gantry crane includes an anchor pin 1, which is slidably installed in a fixed seat 2. A handle 13 is fixedly installed on the surface of the anchor pin 1, and the handle 13 slides in cooperation with a movable groove 14 opened on the surface of the fixed seat 2. The fixed seat 2 is fixedly installed on a fixed plate 15, and the fixed plate 15 is fixedly installed on the bottom of a crane body 16. By arranging the handle 13 for use with the movable groove 14, the anchor pin 1 can be driven to move up and down inside the fixed seat 2, and the upper and lower positions of the anchor pin 1 can be fixed by moving the handle 13 to the horizontal groove on one side of the top and bottom of the movable groove 14.

[0026] It also includes an anchor seat 3, which has an anchor groove 4 inside for use with the anchor pin 1. An alignment plate 17 is fixedly installed on the top surface of the anchor seat 3, and an alignment hole 18 is provided at the center of the surface of the alignment plate 17. The alignment hole 18 is provided directly above the anchor groove 4. The alignment hole 18 is bucket-shaped with a larger top and a smaller bottom. By providing the anchor groove 4 for use with the anchor pin 1, the crane body 16 can be anchored, and by providing the alignment hole 18 on the alignment plate 17, the anchor pin 1 can be easily aligned and inserted into the anchor groove 4.

[0027] The top of the spring 7 is in contact with the bottom surface of the baffle 5, and the bottom surface of the spring 7 is fixedly connected to the bottom surface of the anchor groove 4. The baffle 5 is pushed to block the notch of the anchor groove 4 to prevent foreign matter from entering the anchor groove 4. When anchoring, the downward pressure applied to the anchor pin 1 is greater than the elastic force of the spring 7 to push the baffle 5 downward, ensuring that the anchor pin 1 can be inserted normally.

[0028] The adjusting groove 8 is fixedly provided with a threaded sleeve 9 on both sides of the adjusting groove 8, and a threaded rod 10 is installed on the inner thread of the threaded sleeve 9. A tightening plate 11 is rotatably installed on one end of the threaded rod 10, and a rotating handle 12 is fixedly installed on the other end of the threaded rod 10. By setting two groups of threaded rods 10 and the tightening plate 11, the anchor seat 3 can be tightened in the adjusting groove 8 for fixation, and the position of the anchor seat 3 can be adjusted by rotating the two groups of rotating handles 12, thereby adjusting the position of the anchor groove 4, which is convenient for aligning the anchor pin 1; limit blocks 19 are fixedly installed on both sides of the bottom of the adjusting groove 8, and the limit blocks 19 are slidably matched with the limit grooves 20 opened on both sides of the bottom of the anchor seat 3. The adjusting groove 8 is welded to the bottom plate 21, and the bottom plate 21 is fixed to the ground. By setting the limit blocks 19 and the limit grooves 20 in conjunction with each other, the stability of the anchor seat 3 can be improved.

[0029] When in use, the device is moved to the designated position, the fixing plate 15 is installed to the bottom of the crane body 16, and the bottom plate 21 is fixed to the ground at the designated position. When the crane body 16 needs to be anchored, the crane body 16 is moved to the position of the anchor seat 3, and the anchor pin 1 is aligned with the anchor groove 4 as much as possible. Then, the position of the anchor pin 1 and the anchor groove 4 is observed, and the threaded rod 10 can be driven to rotate in the threaded sleeve 9 by rotating the right rotating handle 12 in the forward direction, so that the threaded rod 10 pushes the tightening plate to push the anchor seat 3 and the anchor groove 4 to move to the left. Similarly, rotating the left rotating handle 12 in the forward direction can make the anchor groove 4 Move to the right, move the anchor groove 4 to directly below the anchor pin 1 by rotating the two sets of rotating handles 12, then rotate the handle 13 to the vertical slot position of the movable slot 14, push the handle 13 downward, the handle 13 drives the anchor pin 1 to move downward, pass through the alignment hole 18, and then push the baffle 5 to compress the spring 7. When the handle 13 moves to the bottom of the movable slot 14, rotate the handle 13 to move the handle 13 to the horizontal slot on one side of the bottom of the movable slot 14 to lock the anchor pin 1, and then rotate the two sets of rotating handles 12 to press the two sets of clamping plates against both sides of the anchor seat 3 to fix the position of the anchor seat 3 and the anchor groove 4, thereby completing the anchoring of the crane body 16.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
