Description

Technical Field

[0001] The utility model belongs to the technical field of lifting tools, and particularly relates to a flexible buffer rotating lifting tool. Background Art

[0002] At present, in the production factories of various industries, the hoisting and transfer of object parts and the like are routine operations, and the objects need to be placed at predetermined positions. In most cases, the staff will first hoist the object in place, and after putting it down, use other tools to straighten the object; or use a hoisting tool with a built-in rotation function to place the object in place at one time. When the hoisting tool rotates, a rotational resistance moment will be generated. At the same time, during the transfer process, it is inevitable to collide with other objects, causing the hoisting tool to deflect under external force. In both cases, the hoisting tool itself and its related connecting parts will be damaged to a certain extent. Therefore, the existing hoisting tools still need to be improved and developed.

The top end of the flexible connector 2 is fixedly connected to the bottom of the upper connecting plate 1, and the bottom end of the flexible connector 2 is fixedly connected to the top of the lower connecting plate 4. The flexible connector 2 bears its own weight and the weight of the suspended object, and at the same time allows it to deflect at a certain angle in the vertical direction.

The resistance moment generated by its own rotation or external object collision is offset by the tension and compression self-resetting structure 3, effectively playing the role of energy dissipation and vibration reduction, and resetting by relying on the internal force of the structure and its own gravity, and the action is gentle.

[0035] The rotation driving structure 5 is installed on one side of the bottom surface of the lower connecting plate 4. Through the rotation driving structure 5, the lifting appliance can place the goods in the predetermined orientation at one time without secondary handling.

[0037] In a further optimized solution, the tension and compression self-resetting structure 3 includes at least two first rigid connecting columns 301. The first rigid connecting columns 301 are fixedly connected to the bottom surface of the upper connecting plate 1, and several first rigid connecting columns 301 are arranged at equal intervals along the circumference of the upper connecting plate 1.

[0038] At least two second rigid connecting columns 302. The second rigid connecting columns 302 are fixedly connected to the top surface of the lower connecting plate 4, and several second rigid connecting columns 302 are arranged at equal intervals along the circumference of the lower connecting plate 4. Several first rigid connecting columns 301 and several second rigid connecting columns 302 are arranged in an alternating manner.

[0039] The bottom of the first rigid connecting column 301 is connected to the top of the adjacent second rigid connecting column 302 through a telescopic part.

[0040] In a further optimized solution, the telescopic part includes a telescopic rod 303. One end of the telescopic rod 303 is hinged to the bottom of the corresponding first rigid connecting column 301, and the other end of the telescopic rod 303 is hinged to the top of the corresponding second rigid connecting column 302.

[0041] In a further optimized solution, several telescopic rods 303 are located on the same horizontal plane.

[0042] For a further optimized solution, first hinge seats are provided on both sides of the bottom of the first rigid connection column 301, and second hinge seats are provided on both sides of the top of the second rigid connection column 302. One end of the telescopic rod 303 is hinged to the first hinge seat, and the other end is hinged to the second hinge seat.

[0043] As Figure 2 shown, first rigid connection columns 301 are provided at the three o'clock and nine o'clock positions of the upper connection disc 1, and second rigid connection columns 302 are provided at the zero o'clock and six o'clock positions of the lower connection disc 4. Both ends of the telescopic rod 303 are respectively connected to the first rigid connection column 301 and the second rigid connection column 302. The length of the flexible connection member 2 is adjusted so that several telescopic rods 303 are on the same horizontal plane and are not stressed in the vertical direction. The telescopic rod 303 can be structures such as a damper, a buffer, a gas spring, etc., and the present utility model does not make specific limitations.

[0044] For a further optimized solution, the rotary drive structure 5 includes a drive motor fixedly connected to one side of the bottom surface of the lower connection disc 4. The output end of the drive motor is axially connected with a driving wheel, and a driven wheel is meshed and connected to one side of the driving wheel.

[0046] When the present utility model is in use, the hoisting tool is run above the object to be lifted by a hoisting device, lowered, the object to be lifted is connected and fixed to the hoisting connection member 6, and then lifted. The object to be lifted is hoisted to a designated position, lowered by a certain height, and the hoisting connection member 6 and the object to be lifted are rotated to a predetermined orientation by the rotary drive structure 5, and the object to be lifted is lowered to complete the hoisting and transfer process. In this process, when the hoisting tool rotates during the start of the self-rotation movement or under other external forces, relative movement occurs between the upper connection disc 1 and the lower connection disc 4, and the flexible connection member 2 deflects in the vertical direction. At the same time, several tension and compression self-resetting structures 3 respectively perform stretching or compression movements, generating an energy dissipation and vibration damping effect, effectively offsetting the rotational resistance generated by the rotational movement, and protecting the hoisting tool itself and the upper connecting members from damage; afterwards, under the action of the internal force of the tension and compression self-resetting structure 3 and the self-weight of the hoisting tool, the upper connection disc 1 and the lower connection disc 4 are restored to the initial position state. During the whole process, the energy generated by the rotational resistance is offset by the tension and compression self-resetting structure 3, and the action is smooth.
