Description

Technical Field

[0001] The utility model relates to the technical field of workpiece transfer, in particular to a hollow piece transfer tool. Background Art

[0002] Ring-shaped workpieces are a common type of structure to be processed or processed. At present, when transferring them, ropes are inserted into the workpieces and the two ends of the ropes are hooked on the hooks of the lifting device. In actual operation, cylindrical workpieces are often placed vertically, which is inconvenient to put the ropes through. If the workpieces are pushed, it is easy to cause safety accidents. In addition, it is difficult to push heavy workpieces. Utility Model Content

[0003] The utility model provides a hollow piece transfer tool to solve the above-mentioned deficiencies in the prior art and the problem that cylindrical ring pieces are inconvenient to be lifted and transferred, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A hollow workpiece transfer tool comprises an upper plate, a vertical rod is provided on the upper plate, a lifting ring is provided on the vertical rod, and a lifting hook of a lifting device can be hooked on the lifting ring, so as to perform a transfer operation of a cylindrical workpiece. The upper plate is provided with screw rods in a circumferential array, a toothed ring is rotatably provided on the upper wall of the upper plate, teeth are respectively provided on the outer periphery and inner periphery of the toothed ring, a plurality of arc holes are provided on the toothed ring, the screw rod passes through the arc holes, a top screw sleeve is provided on the upper end of the screw rod, the lower end of the top screw sleeve is pressed against the upper wall of the toothed ring, a plurality of external gears are meshed on the outer periphery of the toothed ring, a plurality of internal gears are meshed on the inner periphery of the toothed ring, the external gears and the internal gears are coaxially connected with a rotating shaft, the lower end of the rotating shaft is rotatably provided on the upper plate, a rotating arm is provided on the lower end of the rotating shaft, a long hole is provided on the rotating arm, a clamp rod is movably provided in the long hole, the upper end of the clamp rod is fixed to the rotating arm through an upper nut, and the lower end of the clamp rod is fixed to a limit plate through a lower nut. When the gear ring rotates, the outer gear and the inner gear will rotate synchronously. When the outer gear and the inner gear rotate, the clamping rod will be driven to rotate around the axial direction of the outer gear and the inner gear, so that the outer periphery of the clamping rod is tightly attached to the inner and outer walls of the hollow ring, thereby limiting the cylindrical ring. At the same time, the setting of the limit plate can support the transferred workpiece, thereby improving safety during transfer.

[0006] Furthermore, the vertical rod is coaxially arranged on the upper plate to ensure that the workpiece is in a vertical posture during transfer.

[0007] Furthermore, a pair of lugs are provided on the outer periphery of the tensioning sleeve to facilitate the rotation of the tensioning sleeve and fix the rotation angle of the gear ring.

[0008] Furthermore, a plurality of holding rods are provided on the gear ring to facilitate the rotation operation of the gear ring.

[0009] Furthermore, a waist-shaped hole is provided on the limiting plate, and the lower end of the clamp rod is inserted into the waist-shaped hole. The setting of the waist-shaped hole facilitates the position adjustment of the limiting plate to adapt to the limiting operation of different cylindrical rings.

[0010] The advantages of the above technical solution are:

[0011] The utility model facilitates the fixing of the cylindrical ring during transfer and can ensure the safety during transfer. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0013] Figure 1 The three-dimensional structure of one embodiment is shown Figure 1 .

[0014] Figure 2 The three-dimensional structure of one embodiment is shown Figure 2 . DETAILED DESCRIPTION

[0015] like Figure 1~Figure 2 As shown, a hollow piece transfer tool comprises an upper plate 1 , on which a vertical rod 10 is arranged, on which a hanging ring 11 is arranged, and the vertical rod 10 is coaxially arranged on the upper plate 1 .

[0016] The upper plate 1 is provided with screw rods 2 in a circular array, and the upper wall of the upper plate 1 is rotatably provided with a toothed ring 3, and the outer and inner circumferences of the toothed ring 3 are respectively provided with teeth, and the toothed ring 3 is provided with a plurality of arc holes 31, and the screw rods 2 are passed through the arc holes 31, and the upper end of the screw rod 2 is provided with a top screw sleeve 20, and the outer circumference of the top screw sleeve 20 is provided with a pair of lugs 21, and the lower end of the top screw sleeve 20 is pressed against the upper wall of the toothed ring 3, and the toothed ring 3 is provided with a plurality of holding rods 30, and the outer circumference of the toothed ring 3 is meshed with Multiple external gears 4, multiple internal gears 40 are meshed on the inner circumference of the gear ring 3, and the external gears 4 and the internal gears 40 are coaxially connected to a rotating shaft, the lower end of the rotating shaft is rotatably arranged on the upper plate 1, and a rotating arm 41 is arranged at the lower end of the rotating shaft, and a long hole 42 is opened on the rotating arm 41, and a clamping rod 43 is movably arranged in the long hole 42, and the upper end of the clamping rod 43 is fixed to the rotating arm 41 through an upper nut 44, and the lower end of the clamping rod 43 is fixed to a limiting plate 45 through a lower nut 47. A waist-shaped hole 46 is opened on the limiting plate 45, and the lower end of the clamping rod 43 passes through the waist-shaped hole 46.

[0017] When this embodiment is implemented, the operator can transfer the tool to the location where the cylindrical ring is placed, and at this time the cylindrical ring is placed vertically.

[0018] Then the operator inserts the clamp rod 43 onto the cylindrical ring.

[0019] Then the operator rotates the gear ring 3 by holding the rod 30. When the gear ring 3 rotates, each outer gear 4 and the inner gear 40 will rotate synchronously. When the outer gear 4 and the inner gear 40 rotate, the rotating shaft will rotate. The rotation of the rotating shaft will drive the rotating arm to swing, and make the outer periphery of the clamping rod press against the inner and outer peripheries of the cylindrical ring. With the rotation of the clamping rod, the limiting plate 45 will act on the lower end of the cylindrical ring, thereby limiting the lower end of the cylindrical ring. After the limiting is completed, the operator locks the rotation of the gear ring 3 by tightening the thread sleeve 20. After the locking is completed, the operator hooks the lifting device on the lifting ring 11, and then performs the transfer operation of the cylindrical ring.
