Description

Technical Field

[0001] The utility model relates to the technical field of hoisting structures, in particular to a turnover hoisting structure for heavy-loaded workpieces. Background Art

[0002] In the process of producing and assembling heavy-loaded workpieces, it is usually necessary to use a lifting structure to lift them to a specified height. At the same time, when assembling the workpiece, it may be necessary to flip the workpiece to facilitate docking and assembly. At the same time, the selection of specific lifting equipment needs to be considered comprehensively based on factors such as the size, weight, shape and site conditions of the workpiece.

[0003] At present, the patent with announcement number CN219469474U discloses a hoisting and flipping device, including a support column, a mounting plate is movably connected inside the support column, a servo motor is fixedly installed at the bottom of the mounting plate, a threaded shaft is fixedly connected to the output shaft of the servo motor, an adjustment block is threadedly connected to the external thread of the threaded shaft, a drive motor is fixedly installed on the side wall of the adjustment block, a shaft is fixedly connected to the output shaft of the drive motor, a fixed clamp is fixedly connected to the end of the shaft away from the drive motor, a cross plate is fixedly connected to the top of the support column, and a winch is fixedly installed on the top of the cross plate. By adjusting the position of the fixed clamp, it can adapt to workpieces of different sizes, easily flip the workpiece, thereby improving the use efficiency, meeting the use requirements, and having the advantage of strong applicability. The setting of the support slider avoids shaking of the mounting plate when lifting and lowering, and prevents the workpiece from colliding with the support column, and has the advantage of stable lifting and lowering, which solves the problem that the prior art can only clamp and flip workpieces of a single size, and its application range is low.

[0004] However, the following problems still exist during the use of the above-mentioned lifting and turning device: when using the above-mentioned lifting and turning device, during the process of lifting a heavy-loaded workpiece, the lifting rope is in a tilted state during the process of winding and unwinding, and a certain steel wire may be subjected to uneven force, resulting in loss of strength and increased wear of the steel wire. Long-term use of an inclined lifting rope can easily cause the steel wire rope to break, increasing the risk of accidents. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a flip hoisting structure for heavy-loaded workpieces, which can effectively prevent the hoisting rope from being tilted and pulled during the winding or unwinding process by moving.

Through the above structure, it is convenient to support the movable screw without affecting the rotation of the movable screw, and the position of the winch plate can be moved as the movable screw rotates.

[0008] Furthermore, a guide rod is fixedly installed on the lifting frame, and a sliding groove is opened on the lifting plate, and the lifting plate is slidably connected to the guide rod through the sliding groove. Through the above structure, the lifting plate can be supported and limited under the action of the guide rod to avoid shaking of the lifting plate during movement.

[0009] Furthermore, a cylindrical groove is opened in the middle position of the limit plate, and the outer surface of the limit plate is set to be smooth. A push spring is fixedly installed on the limit plate, and the push spring is fixedly installed on the lifting frame. Through the above structure, the lifting rope can be limited by the limit plate, thereby ensuring that the lifting rope can be slightly offset, thereby preventing the lifting rope from being rigidly stretched.

[0010] Furthermore, an additional plate is fixedly installed at the lower end of the lifting plate, a movable motor is fixedly installed at the lower right end of the lifting plate, and a bidirectional screw is installed at the output end of the movable motor, and the bidirectional screw is rotatably installed on the additional plate, and two sections of different-direction thread structures are symmetrically arranged on the left and right sides of the bidirectional screw. Through the above structure, the limiting plate can be moved conveniently with the rotation of the bidirectional screw.

[0011] Furthermore, a limiting plate is provided on the bidirectional screw, and the upper end of the limiting plate and the lower end of the hanging plate are in contact with each other. Through the above structure, it is easy to ensure that the two limiting plates move in different directions.

[0012] Furthermore, a flipping motor is fixedly arranged on the limiting plate, and the output end of the flipping motor is connected to the clamping plate through a rotating shaft. A hemispherical groove is provided on the clamping plate, and a receiving ball is provided in the hemispherical groove provided on the clamping plate. An annular groove is provided on the clamping plate, and the receiving ball is slidably arranged in the annular groove provided on the clamping plate. Through the above structure, the heavy-loaded workpiece can be flipped as the clamping plate rotates.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The overturning and lifting structure of the heavy-loaded workpiece can change the position of the winch plate by rotating the movable screw, and thus the winding roller and the lifting rope can be moved. At this time, it can be ensured that the unwinding or winding lifting rope is in the middle position of the lifting frame, so that the lifting plate can be stably lifted, thereby avoiding the tilt of the lifting rope, and the lifting rope can be slightly offset by the limit plate to ensure that the lifting rope is in the middle position as much as possible. The workpiece can be clamped and fixed by the movement of the limiting plate, and the heavy-loaded workpiece can be overturned as the clamping plate rotates. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] When the workpiece needs to be hoisted and flipped, the moving motor 16 starts working. Since the output end of the moving motor 16 is interconnected with the bidirectional screw 17, the bidirectional screw 17 starts to rotate. Since the bidirectional screw 17 is interconnected with the limiting plate 18 through the second threaded hole opened on the limiting plate 18, as the bidirectional screw 17 rotates, the two limiting plates 18 start to move toward each other until the clamping plate 20 fits tightly with the left and right sides of the heavy-loaded workpiece. After that, the workpiece can be hoisted to the specified height, and then the flipping motor 19 starts working. Since the output end of the flipping motor 19 is interconnected with the clamping plate 20, the clamping plate 20 starts to rotate. Under the action of the receiving ball 21, the clamping plate 20 can be supported and limited, and the heavy-loaded workpiece can be hoisted and flipped.

[0024] A first motor 9 is fixedly mounted on the fixed plate 8, and a moving screw 10 is mounted on the output end of the first motor 9, and the moving screw 10 is rotatably mounted on the fixed plate 8, a hoisting machine plate 2 is arranged on the moving screw 10, and a hoisting motor 3 is fixedly mounted on the hoisting machine plate 2, the output end of the hoisting motor 3 is connected to the winding roller 4, and a lifting rope 5 is fixedly wound around the outside of the winding roller 4, a lifting plate 6 is fixedly mounted on the lower end of the lifting rope 5, a fixed rod 12 is fixedly mounted on the lifting frame 1, and a limit plate 13 is slidably arranged on the fixed rod 12, and the limit plate 13 and the lifting rope 5 are in contact with each other, a pulley group 11 is fixedly mounted on the moving screw 10, and A first bearing is installed on the fixed plate 8, and the fixed plate 8 is rotationally connected with the movable screw 10 through the first bearing.

A push spring 14 is fixedly installed on the limit plate 13, and the push spring 14 is fixedly installed on the hoisting frame 1.

[0025] When the workpiece needs to be hoisted, the hoisting motor 3 starts to work, because the output end of the hoisting motor 3 is connected to the winding roller 4 through the rotating shaft, and the winding roller 4 starts to rotate. Because the hoisting rope 5 is fixedly wound on the winding roller 4, the hoisting rope 5 starts to reel up, and because the lower end of the hoisting rope 5 is connected to the hoisting plate 6, the hoisting plate 6 starts to move upward under the action of the guide rod 7. At the same time, the first motor 9 starts to work, because the output end of the first motor 9 is connected to the moving screw 10, and the moving screw 10 A pulley set 11 is fixedly installed on it, and the moving screw 10 is connected to the winch plate 2 through the first threaded hole opened on the winch plate 2.

The lifting rope 5 can be supported and limited by the limit plate 13 and the push spring 14 to ensure that the lifting rope 5 moves within a smaller range and that the lifting rope 5 can be slightly offset and wound or unwound.
