Description

Technical Field

[0001] The utility model relates to the technical field of cranes for claw machines, and in particular to a rotatable crane for claw machines. Background Art

[0002] In the prior art, circular claw machines still use horizontal and vertical overhead cranes, and the movable area is generally square. In circular or fan-shaped claw machines, there are many blind spots for the grippers, which makes it impossible for the grippers to reach the edge, resulting in the dolls that fall off the edge not being touched by the grippers.

[0003] In the prior art, there is a rotating overhead crane with the announcement number "CN 220695819". This patent sets a motor to drive the aluminum guide rail to swing, so that the aluminum guide rail can move in an arc, which facilitates the aluminum guide rail to be adjusted to the required moving position, so as to facilitate the claw assembly to move along the direction of the aluminum guide rail and reach the required position. However, in this patent, compared with the horizontal and vertical overhead cranes in the existing claw machines, the driving method of the existing overhead crane is changed, so that the driving mechanism of the existing overhead crane needs to be replaced at a higher cost. Moreover, the aluminum guide rail in this patent is not provided with a support mechanism during the arc motion, which reduces its stability and is not conducive to user play. Summary of the Invention

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a rotatable crane for a claw machine.

DETAILED DESCRIPTION

[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0017] like Figure 1-4 The rotatable doll machine crane shown in the figure includes a first mounting seat 5 and a second mounting seat 12, and a clamping claw moving mechanism is provided between the first mounting seat 5 and the second mounting seat 12. One side of the first mounting seat 5 is movably connected with a sleeve seat 3, and a fixed bearing 17 is tightly installed inside the sleeve seat 3. The inner ring of the fixed bearing 17 is tightly fitted with the main shaft 1, and a plane thrust ball bearing 2 is provided between the bottom end of the main shaft 1 and the bottom of the sleeve seat 3. One side of the second mounting seat 12 is movably connected with a slide rail 16, and the slide rail 16 is in an arc shape. During the circular motion of the driving wheel 11 on the slide rail 16, the driving wheel 11 drives the first mounting seat 5 to move synchronously in an arc through the second mounting seat 12 and the two slide rods 9. The first mounting seat 5 drives the sleeve seat 3 to move in an arc on the surface of the main shaft 1 through the fixed bearing 17, thereby improving the stability of the crane during the circular motion.

[0018] The clamping jaw moving mechanism includes a clamping jaw 15, two sliding rods 9 and a transmission rod 8. The two ends of the two sliding rods 9 are respectively mounted on the sides of the first mounting seat 5 and the second mounting seat 12 by screws. A crane travel mechanism is movably provided between the two sliding rods 9. The clamping jaw 15 is connected to the crane travel mechanism. The two ends of the transmission rod 8 are respectively mounted on the sides of the first mounting seat 5 and the second mounting seat 12 by bearings. One end of the transmission rod 8 is fixedly sleeved with a worm gear 7. One side of the transmission rod 8 is provided with a first drive motor 6. The first drive motor 6 is mounted on the side of the first mounting seat 5 by screws. The movable end of the first drive motor 6 is connected to a worm 4, and the worm 4 is meshed with the worm gear 7. The other end of the transmission rod 8 extends to one side of the second mounting seat 12 and is fixedly sleeved with a driving wheel 11. The surface of the driving wheel 11 contacts the top of the slide rail 16. When the first drive motor 6 is powered on, the first drive motor 6 drives the transmission rod 8 to rotate through the cooperation of the worm gear 7 and the worm 4, thereby facilitating the transmission rod 8 to drive the driving wheel 11 to rotate on the slide rail 16, thereby facilitating the driving wheel 11 to drive the overhead crane to move in an arc on the slide rail 16. After the overhead crane is moved to the desired position, the first drive motor 6 can be stopped to complete the arc motion operation of the overhead crane.

[0019] A driven wheel 13 with a corresponding position is provided on one side of the driving wheel 11. A driven shaft 14 is installed at the center position of the driven wheel 13 through a bearing. One end of the driven shaft 14 is installed on the side of the second mounting seat 12 through a screw. The driven wheel 13 and the driving wheel 11 increase the contact area with the slide rail 16, thereby improving the stability of the overhead crane sliding on the slide rail 16.

[0020] A connecting block 18 is installed on the side of the sleeve seat 3 by screws, and a concave part 19 is movably sleeved on the surface of the connecting block 18. A rotating shaft 20 is installed between the two ends of the concave part 19 and the side of the connecting block 18. One end of the concave part 19 is installed on the side of the first mounting seat 5 by screws. After the slide rail 16 is installed in the outer shell of the doll machine, the slide rail 16 needs to be installed horizontally. Due to technical problems of the staff, the slide rail 16 cannot be truly installed horizontally. Therefore, the rotating shaft 20 provides the concave part 19 with an arc motion on the connecting block 18, which facilitates the circular motion of the overhead crane on the slide rail 16.

[0021] In this solution, the crown crane walking mechanism includes a crown crane housing 10, two second worm gears 21, two movable shafts 22, two second worm gears 23, four walking wheels 24, a third mounting seat 25, a second drive motor 26, a third drive motor 27 and three pulleys 28. The crown crane housing 10 is sleeved between the surfaces of the two slide rods 9, the third mounting seat 25 is mounted on the inside of the crown crane housing 10 by screws, the second drive motor 26 and the third drive motor 27 are both mounted on the side of the third mounting seat 25 by screws, the two second worm gears 21 are respectively mounted on the movable ends of the second drive motor 26 and the third drive motor 27, the two movable shafts 22 are both mounted on the side of the third mounting seat 25 through bearings, the two second worm gears 23 are respectively fixedly sleeved on the surfaces of the two movable shafts 22, the two second worm gears 23 and the two second worm gears 21 are respectively meshed, wherein the two walking wheels 24 are fixedly sleeved on the two ends of the movable shaft 22, and the other two walking wheels 24 are sleeved on the two ends of another movable shaft 22 through bearings, and the four walking wheels 24 are respectively engaged with the two slide rods 9. The third drive motor 27 controls the rotation of the other movable shaft 22, and the other movable shaft 22 drives one of the pulleys 28 to rotate to retract or release the rope, so that the length of the rope connected to the clamping jaw 15 changes, which is used to adjust the vertical movement of the clamping jaw 15; the second drive motor 26 drives the two walking wheels 24 to roll on the top of the two slide bars 9 by controlling the movable shaft 22, which is used to drive the clamping jaw 15 to move horizontally, facilitating the travel of the overhead crane. The driving mode of the clamping jaw 15 is to generate a magnetic force to attract the iron block after the electromagnet inside it is energized. During the upward movement of the iron block, multiple claw hooks in the clamping jaw 15 are pulled close to complete the clamping operation. After the electromagnet is powered off, the magnetic force disappears, and during the downward movement of the iron block, multiple claw hooks are unfolded to complete the release operation.
