the rotating assembly can move up and down in the lifting area under the control of the lifting assembly.
Furthermore, one lifting assembly is arranged below each rotary tire.
Furthermore, the bottom plate is provided with an opening corresponding to the lifting assembly, a supporting column of the lifting assembly penetrates through the opening, and the top end of the supporting column abuts against the bottom of the support.
Further, the lifting assembly is specifically a hydraulic jack.
Furthermore, the sliding assembly further comprises a limiting assembly, the limiting assembly is arranged at the opening, and the supporting column penetrates through the limiting assembly.
Furthermore, lifting lugs are arranged at the tops of the side columns.
The utility model has the technical effects that: the steel pipe lifting device is simple in lifting arrangement, a steel pipe is placed between the two rotary tires, the lifting assembly can be started to achieve the purpose of controlling the lifting of the rotary tires, so that the steel pipe can be separated from the V-shaped roller, the longitudinal and circumferential movement of the steel pipe can be effectively ensured to be smoothly carried out in the steel pipe group lengthening operation, the equipment integrity of an operation line is ensured, the potential safety risk caused by incomplete transfer of acting forces of the rotary tires and the V-shaped roller is reduced, and the construction efficiency is improved.

Description of reference numerals: 1. rotating the tire; 2. a support; 3. a side post; 4. a base plate; 5. lifting lugs; 6. a jack; 7. and a limiting component.
Detailed Description
The present invention is further described with reference to the following drawings and specific examples so that those skilled in the art can better understand the present invention and can practice the present invention, but the examples are not intended to limit the present invention.
As shown in fig. 1, an embodiment of the present invention provides a liftable auxiliary fixture for turning a tire for steel pipe extension, and each step is specifically implemented as follows:
the utility model provides a liftable child auxiliary fixtures that changes for steel pipe extension, includes runner assembly, slip subassembly and lifting unit, in the runner assembly located supporting component's lift region, lifting unit can control runner assembly and reciprocate in the lift region to reach and change child 1 support and the separation to the steel pipe, thereby reduced the risk of operation.
The rotating assembly comprises a support 2 and two rotary tires 1 fixed on the top of the support 2, and a steel pipe is arranged between the two rotary tires 1. The rotating tire 1 can rotate relative to the support 2, so that when the steel pipe placed on the rotating tire 1 moves in the annular direction, the sliding friction between the steel pipe and the surface of the rotating tire 1 is avoided, and the surface damage of the steel pipe is avoided. Support 2 is formed by four triangle steel end to end welding, and wherein the both sides face of triangle steel is located the top respectively and all around, makes the bottom of support 2 form the joint region, and the joint region is located at the top of lifting unit's support column in to support and lean on in the bottom surface of support 2, can prevent that the support column from sliding for support 2.
The sliding assembly comprises a bottom plate 4 and 4 side columns 3, wherein the 4 side columns 3 enclose a lifting area, the rotating assembly is arranged in the lifting area, and the side surface of the support 2 is in contact with the inner side surface of the side column 3 and can freely slide relatively. The top end of each side column 3 is provided with a lifting lug 5 for hoisting the utility model in place.
The lifting component is a jack 6. In this embodiment, the number of jacks 6 is two, and the corresponding openings of the bottom plate 4 are also provided with two. The jack 6 is provided with a support column which passes through the open hole. Still be equipped with spacing subassembly 7 in trompil department, spacing subassembly 7 is made for the drum, and on the surface was fixed in the bottom plate 4 of trompil department, the support column passed from the drum is inside, and limit structure can prevent 6 hydraulic jack 6 from taking place to empty the phenomenon under receiving pressure and vibration effect.
In the embodiment, the steel pipe hoop extension device can be hung to a steel pipe assembly extension line by using four lifting lugs 5 when in use, when the steel pipe is required to rotate annularly, the rotating tire 1 is lifted and displaced by two hydraulic jacks 6, the acting force of the steel pipe is completely transferred to the rotating tire 1, the steel pipe is guaranteed to be separated from a V-shaped roller in the line, the steel pipe hoop rotation can be realized by the rotation of the rotating tire 1, and the falling phenomenon of the hydraulic jacks 6 under the action of pressure and vibration can be prevented by limiting structures arranged at the bottoms of the two hydraulic jacks 6. When the steel pipe is not required to rotate annularly, the height of the rotary tire 1 can be reduced through the hydraulic jack 6, so that the rotary tire 1 is separated from the steel pipe.
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto.
