The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0021] Those skilled in the art should understand that, in the disclosure of the specification, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0022] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0023] refer to Figure 1 and Figure 2, the embodiment of the present application provides a casing device for inserting a first steel pipe into a second steel pipe. The casing device includes a steel pipe support 10 and an electric winch 20, wherein the steel pipe support 10 includes a first baffle 11 and two supporting steel pipes 12, wherein the two supporting steel pipes 12 extend in parallel in the same height direction and are gap-matched, and at the same time, the steel pipe support 10 forms a limiting structure suitable for accommodating the second steel pipe above the gap between the two supporting steel pipes 12, thereby taking advantage of the fact that the steel pipe production enterprise has a large number of scrapped steel pipes and using local materials, making the casing device easier to manufacture and form, and at the same time, the steel pipe itself has strong hardness and roundness, which is suitable for supporting the steel pipe to be inserted into the casing. The first baffle 11 is fixedly connected to one end of the two supporting steel pipes 12, and protrudes from the supporting steel pipe 12 in the height direction to limit the second steel pipe and prevent the second steel pipe from moving along the insertion direction during the casing process. The electric winch 20 is located on the side of the first baffle 11 away from the supporting steel pipe 12 and facing the limiting structure. At the same time, the wire rope 21 on the electric winch 20 extends to the other side of the limiting structure, so that when the end of the first steel pipe is placed into the second steel pipe, the first steel pipe can be pulled at the other end of the first steel pipe so that the first steel pipe can be gradually inserted into the second steel pipe.

[0024] In the actual operation process, the second steel pipe is firstly lifted to the top of the gap between the two supporting steel pipes 12 by a crane, and the second steel pipe is supported by the two supporting steel pipes 12. Then, the second steel pipe is slightly moved so that one end thereof abuts against the first baffle 11 to limit the second steel pipe. Subsequently, the first steel pipe is lifted to the end of the second steel pipe away from the first baffle 11 by a crane, and then the steel wire rope 21 on the electric-controlled hoist 20 is fixed to the other end of the first steel pipe. The first steel pipe is made to face the lumen of the second steel pipe by the crane. With the traction of the steel wire rope 21 on the electric-controlled hoist 20, the first steel pipe gradually enters the second steel pipe. When the first steel pipe enters more than half, the crane can be moved elsewhere. Only the electric-controlled hoist 20 is needed to completely insert the first steel pipe into the second steel pipe. The operation is very convenient, which greatly reduces the degree of human participation, makes it safer to wear the casing, and at the same time, the work efficiency is greatly improved, and the labor intensity is reduced.

[0025] In one embodiment, the steel pipe support 10 also includes a first support 13 and a second support 14 respectively supported at both ends of the two supporting steel pipes 12. At the same time, the two supporting steel pipes 12 are welded to the first support 13 and the second support 14 in a suspended manner, and the first baffle 11 is welded to the second support 14 and maintained vertically with the two supporting steel pipes 12. Therefore, by designing the supporting steel pipe 12 in a suspended manner, the supporting steel pipe 12 can be placed in a relatively dry environment, not easily affected by moisture, and can maintain good roundness for a long time, with a longer service life. At the same time, the suspended design also facilitates the adjustment of the horizontality of the two supporting steel pipes 12, thereby making it suitable for good support and limiting of the steel pipe to be inserted, that is, the second steel pipe.

[0026] In one embodiment, the first bracket 13 and the second bracket 14 are both formed by welding I-beams.

[0027] Further preferably, the steel pipe support 10 further includes two reinforcing ribs 15. The two reinforcing ribs 15 are symmetrically welded between the outer ends of the two supporting steel pipes 12 and the first baffle 11, and extend in the horizontal direction, thereby increasing the connection area between the supporting steel pipe 12 and the first baffle 11, making the supporting steel pipe 12 more stable, and thus improving the structural connection strength of the sleeve insertion device as a whole.

[0028] Considering that the steel pipe is generally long during the process of inserting the casing, the supporting steel pipe 12 has a long length, which results in poor structural strength and stability near the middle position. Therefore, in one embodiment, at least one group of transition support pipes 16 is further provided between the two supporting steel pipes 12 and the first bracket 13 and the second bracket 14, such as providing a group of transition support pipes 16 in the middle of the supporting steel pipes 12, or evenly providing two or three groups of transition support pipes 16 between the first bracket 13 and the second bracket 14. The transition support pipe 16 extends in the horizontal direction and is vertically connected to the outside of the two supporting steel pipes 12. Meanwhile, a support foot 161 is provided at the bottom of the transition support pipe 16, and the support foot 161 and the first bracket 13 and the second bracket 14 are located at the same height direction, thereby providing additional support to the supporting steel pipe 12 through the transition support pipe 16 to ensure the structural strength of the longer supporting steel pipe 12 near the middle position and the support stability of the second steel pipe.

[0029] In one embodiment, the first bracket 13 includes a top plate 131 welded to the support steel pipe 12. The top plate 131 and the top of the support steel pipe 12 remain parallel, and the top plate 131 vertically extends outward from the support steel pipe 12 by a predetermined length, thereby providing a larger support area in the horizontal direction, preventing the first steel pipe or the second steel pipe from directly sliding or rolling down, and further improving the operational safety.

[0030] Further preferably, the top plate 131 is vertically connected to a second baffle 132 at one end away from the supporting steel pipe 12, and the second baffle 132 protrudes upward from the supporting steel pipe 12 to prevent the steel pipe from sliding or rolling to the outside, so as to further improve operational safety.

[0031] It should be noted that the terms "first, second" in the present application are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0032] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
