Detailed Embodiments

[0019] The present invention will be further described in detail below with reference to the drawings.

[0020] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6The following shows an embodiment of the present invention, in which a hoisting tool for a cavity column is disclosed, including a support bracket 1, a limiting frame 2, a hoisting belt 3, a limiting disc 4 and a straightening mechanism 5. The support bracket 1 is used to support the bottom of the cavity column, and the limiting frame 2 is used to abut against the upper end position of the inner wall of the cavity column.

[0021] As Figure 1 shown, one end of the hoisting belt 3 is fixedly connected to the middle position of the support bracket 1, and the other end can pass through the limiting frame 2 and be connected to the lifting hook of an external hoisting device. The limiting disc 4 is fixed on the hoisting belt 3, and the limiting disc 4 can abut against the bottom of the limiting frame 2. The straightening mechanism 5 is used to lift the cavity column to a vertical state, that is, the straightening mechanism 5 can straighten the cavity column to a vertical state to ensure that the cavity column is in a vertical state when leaving the ground.

[0022] As Figure 1 、 Figure 2 shown, the straightening mechanism 5 includes a receiving frame 51 and a straightening frame 52. The receiving frame 51 is perpendicularly and fixedly connected to the straightening frame 52 so that the receiving frame 51 and the straightening frame 52 form an L-shaped structure, and the receiving frame 51 is used to connect with the limiting frame 2. The straightening mechanism 5 further includes a limiting block 53, and the limiting block 53 is used to abut against the end of the straightening frame 52 far from the receiving frame 51. A plurality of fastening pins 54 are arranged on the limiting block 53, and the plurality of fastening pins 54 are used to nail into the ground layer to realize the fixation of the limiting block 53 to the ground layer. At the same time, a support block 55 for the receiving frame 51 to abut against and be limited is perpendicularly and fixedly connected to the limiting block 53, and the limiting block 53 and the support block 55 form an L-shaped structure.

[0023] As Figure 3 shown, when the cavity column is hoisted, the cavity column is usually horizontally placed on the hoisting platform. At this time, the limiting frame 2 is abutted and limited against the inner wall of the cavity column, and the support bracket 1 is abutted against the bottom of the cavity column. Then, the hoisting belt 3 is passed through the limiting frame 2, and the hoisting belt 3 is connected to the lifting hook of an external hoisting device. Subsequently, the limiting block 53 is fixed to the ground layer through the fastening pins 54, and the end of the straightening frame 52 far from the receiving frame 51 is abutted against the side wall of the limiting block 53, and then the cavity column is hoisted by the hoisting device.

[0024] As Figure 4 shown, during the process of slowly hoisting the cavity column, the straightening frame 52 flips under the abutting action of the limiting block 53, that is, the straightening frame 52, the receiving frame 51 and the cavity column flip synchronously. When the receiving frame 51 abuts against the support block 55, the straightening frame 52 is in a vertical state and the receiving frame 51 is in a horizontal state. At this time, the cavity column is in a vertical state, thereby realizing the straightening of the cavity column and ensuring that the cavity column is in a vertical state when leaving the ground, so as to facilitate the vertical hoisting of the cavity column by the staff.

[0025] As Figure 1 、Figure 2 As shown, the end of the straightening frame 52 away from the receiving frame 51 is integrally formed with a guide arc surface 56, and the guide arc surface 56 abuts against the side wall of the limit block 53 to improve the guiding effect, so that the straightening frame 52, the receiving frame 51 and the cavity column can be turned over smoothly. The straightening frame 52 is connected to the receiving frame 51 through a plurality of inclined reinforcing rods 57 to improve the strength of the connection structure between the straightening frame 52 and the receiving frame 51, thereby improving the compression resistance.

[0026] like Figure 1 , Figure 2 As shown, a plurality of positioning holes 58 are provided through the receiving frame 51, and the connecting sleeve at the bottom of the cavity column can be inserted into the corresponding positioning hole 58, thereby realizing the positioning of the receiving frame 51 and the cavity column, and ensuring that the receiving frame 51 and the cavity column can be smoothly and synchronously flipped.

[0027] like Figure 2 , Figure 5 As shown, the support bracket 1 includes a cross-shaped support frame 11, the lifting belt 3 is fixedly connected to the middle position of the support frame 11, a limiting groove 59 is provided on the receiving frame 51, and the support frame 11 can be inserted into the limiting groove 59, thereby realizing the positioning between the receiving frame 51 and the support frame 11.

[0028] Since the positioning hole 58 on the receiving frame 51 is positioned with the connecting sleeve at the bottom of the cavity column, and the support frame 11 is positioned with the limiting groove 59 on the receiving frame 51, the cavity column is ensured to be centered on the support frame 11, that is, the support frame 11 can vertically lift the cavity column to ensure that the cavity column can be lifted vertically. In addition, the support frame 11 is movably connected to the receiving frame 51, and when the cavity column is lifted, the straightening mechanism 5 can automatically fall off, improving the convenience of operation.

[0029] like Figure 4 , Figure 5 As shown, the four ends of the support frame 11 are respectively vertically fixedly connected with a first positioning plate 12 and a second positioning plate 13. The first positioning plate 12 can abut against the inner wall of the cavity column for limiting position, and the second positioning plate 13 can abut against the outer wall of the cavity column for limiting position, thereby improving the limiting effect between the support frame 11 and the cavity column to ensure that the support frame 11 can vertically support the cavity column.

[0030] like Figure 1 , Figure 6As shown in the figure, the limiting frame 2 includes a limiting ring 21. The hoisting belt 3 can pass through the limiting ring 21, and the limiting disc 4 can abut against the bottom of the limiting ring 21 for limiting. A plurality of hinge seats 22 are fixedly connected to the limiting ring 21. The plurality of hinge seats 22 are arranged at equal intervals along the circumference of the limiting ring 21. A limiting wheel 23 is rotatably connected to each hinge seat 22. A limiting plane 24 is provided on the limiting wheel 23, and the limiting plane 24 can closely abut against the inner side wall of the cavity column.

[0031] Put components such as the limiting ring 21 into the cavity column. At this time, the limiting plane 24 closely abuts against the inner side wall of the cavity column. After connecting the hoisting belt 3 to the lifting hook of the external hoisting equipment, the limiting disc 4 abuts against the limiting ring 21. When hoisting the cavity column, the limiting wheel 23 has a tendency to rotate downward. Then, a limiting tip is formed at the intersection position between the upper end of the limiting plane 24 and the outer side wall of the limiting wheel 23, and this limiting tip can more tightly abut against the inner side wall of the positioning column to ensure the stable connection between the limiting frame 2 and the cavity column. At the same time, the limiting disc 4 abuts against the limiting ring 21 for limiting, so that the limiting frame 2 also bears the tension to share the force borne by the support bracket 1, thereby ensuring the smooth hoisting of the cavity column.

[0032] As Figure 1 、 Figure 6 shown in the figure, the center position of the limiting ring 21 is aligned with the center position of the support frame 11. A step groove 25 is provided at the bottom of the limiting ring 21, and the limiting disc 4 can be tightly clamped into the step groove 25, thereby realizing the positioning of the limiting disc 4 and the limiting ring 21 to ensure that the hoisting belt 3 is in a vertical state and the hoisting belt 3 is centered inside the cavity column, so that the cavity column can be hoisted vertically.

[0033] This embodiment also discloses a method for hoisting a cavity column. Using the above hoisting tooling, the hoisting method includes the following steps: S1. Clamp the support frame 11 into the limiting groove 59, control components such as the receiving frame 51 to move towards the cavity column, and make the plurality of limiting sleeves on the cavity column respectively pass through the corresponding positioning holes 58 until the support frame 11 abuts against the cavity column. Then fixedly connect the limiting block 53 to the formation and ensure that the guiding arc surface 56 abuts against the side wall of the limiting block 53.

[0034] Subsequently, place the limiting frame 2 into the cavity column according to the position of the limiting disc 4, pass the hoisting belt 3 through the limiting ring 21, and make the limiting disc 4 snap into the step groove 25. During this process, ensure that the hoisting belt 3 is straightened, and the plurality of limiting planes 24 respectively abut tightly against the inner side wall of the cavity column. Finally, connect the hoisting belt 3 to the lifting hook of the external hoisting equipment.

[0035] S2. Apply a pulling force to the hoisting belt 3 through the hoisting equipment to slowly lift the cavity column; S3, during the process of slowly lifting the cavity column, the straightening frame 52 is turned over under the abutment of the limit block 53, that is, the straightening frame 52, the receiving frame 51 and the cavity column are turned over synchronously. When the receiving frame 51 abuts against the support block 55, the straightening frame 52 is in a vertical state and the receiving frame 51 is in a horizontal state. At this time, the cavity column is in a vertical state, thereby realizing the straightening of the cavity column and ensuring that the cavity column is in a vertical state when it leaves the ground; S4, vertically lift the cavity column to the required position by lifting equipment.

[0036] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
