DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, purposes and effects of the utility model more clear and easy to understand, the technical solutions in the utility model are further described below in combination with the drawings and examples.

[0023] Please refer to Figs. 1-3 As shown in the figure, a steel casing hoisting device, comprising: a center plate 1, a sling 2, a lower ring 3, a sliding plate 4 and an arc hoop plate 5; the center plate 1 is provided with a first lifting ring 11 at the top center, and a vertical rod 12 is fixedly connected between the center plate 1 and the lower ring 3; the sliding plate 4 is provided with a plurality of sliding plates 4, which are arranged along the circumference of the lower ring 3, and the sliding plates 4 slide through the lower ring 3 along the radial direction of the lower ring 3, and one end of the sliding plate 4 outside the lower ring 3 is fixedly connected with the inner side upper part of the arc hoop plate 5, and the center plate 1 is provided with a control assembly for controlling the sliding of the sliding plate 4; the arc hoop plate 5 is provided with a second lifting ring 51 at the top, the sling 2 is connected between the second lifting ring 51 and the center plate 1, and the arc hoop plate 5 is provided with a connecting hole for connecting with the steel casing, a screw rod is arranged in the connecting hole, a nut is threadedly connected on the screw rod, and a rubber pad 52 is arranged on the inner side of the arc hoop plate 5.

[0024] The first lifting ring 11 is arranged on the center plate 1, which is used for hoisting with a crane; the vertical rod 12 is fixedly connected between the center plate 1 and the lower ring 3, which avoids relative rotation of the center plate 1 and the lower ring 3; the sliding plate 4 can slide radially along the lower ring 3, and when the sliding plates 4 are all slid to the inner side of the lower ring 3, the arc hoop plate 5 can be brought together to clamp the steel casing; the arc hoop plate 5 is provided with a connecting hole, and in use, a through hole is formed on the steel casing corresponding to the connecting hole, a screw rod is passed through the through hole and the connecting hole from the inside of the steel casing, and a nut is tightened to fix the steel casing and the arc hoop plate 5; the rubber pad 52 is arranged on the inner side of the arc hoop plate 5, so that the arc hoop plate 5 is tightly attached to the outer wall of the steel casing when the steel casing is fixed with the arc hoop plate 5; the sling 2 connects the arc hoop plate 5 and the center plate 1, so that the steel casing is hoisted through the first lifting ring 11. The sliding plate 4 is controlled by the control assembly to drive the arc hoop plate 5 to move, the size of the space formed by the plurality of arc hoop plates 5 is changed, and different diameters of steel casings can be hoisted.

[0025] Further, as Figs. 1-3As shown, the control assembly includes a rotating column 61, a rotating plate 62, and a pull plate 63. The upper end of the rotating column 61 is rotatably mounted on the central plate 1 along its axial direction. Several rotating plates 62 are provided, each corresponding to a sliding plate 4. These rotating plates 62 are fixed circumferentially to the lower part of the rotating column 61. The pull plate 63 is hinged at both ends between the rotating plate 62 and the sliding plate 4. When the rotating column 61 rotates, it drives the rotating plate 62 to rotate as well. The rotating plate 62 pulls the pull plate 63, which in turn moves the sliding plate 4. Since the sliding plate 4 passes through the lower ring 3, the lower ring 3 restricts its movement, allowing it to move only radially along the lower ring 3. This causes the arc-shaped clamps 5 to move closer together or further apart.

[0026] Furthermore, such as Fig. 1 As shown, the specific structure for controlling the rotation of the rotating column 61 includes a motor mounted on the center plate 1. The motor's output shaft is coaxially connected to a vertical shaft 71, on which a driving gear 72 is coaxially fixed. A driven gear 73 meshes with the driving gear 72 on the rotating column 61. The motor drives the vertical shaft 71 to rotate, thereby causing the driving gear 72 on the vertical shaft 71 to rotate. The driven gear 73 then meshes with the driving gear 72, thus rotating the driven gear 73 and controlling the rotation of the rotating column 61.

[0027] Furthermore, multiple sliding plates 4 can be provided; in this embodiment, four are provided.

[0028] Furthermore, in order to improve the stability of the hoisting, the second lifting ring 51 is fixed to the middle of the upper surface of the arc-shaped hoop plate 5.

[0029] Furthermore, in order to make the connection between the arc-shaped hoop 5 and the steel casing more reliable, each of the arc-shaped hoop 5 is provided with two connection holes, and the two connection holes are located on both sides of the second lifting ring 51.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
