Abstract
Description
Technical Field:
[0001] The utility model relates to the technical field of pipeline installation, in particular to a pipe orifice butt joint device for steel pipe installation. Background Art:
[0002] In water conservancy projects, welded steel pipes are usually used for long-distance fluid transportation. During the construction of steel pipe welding, the orifices of two welded steel pipes need to be aligned. If the orifices are not aligned properly, it is easy to cause problems such as inability to weld or cracking of the steel pipe weld after misaligned welding.
[0003] Affected by the length and weight of the steel pipe, it is easy to be misaligned when manually adjusting the alignment. It is very difficult to ensure the neat butt joint of the orifices, and it takes a long time and the construction efficiency is low. The method of fixing with a clamp has a single applicable pipe diameter. The method of fixing with a chuck fixes the steel pipe through the cooperation of a ratchet tooth and a ratchet pawl. When the ratchet pawl falls into the ratchet tooth slot, there will be a rebound, and the rebound gap will cause the pipeline to be fixed not tightly; the chuck is fixed on the base, which also limits the use of the fixture, such as field construction. Content of the Utility Model:
[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a pipe orifice butt joint device for steel pipe installation.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a pipe orifice butt joint device for steel pipe installation, which includes two circular chucks. It is characterized in that the two chucks are connected by a plurality of distance rods; it also includes two C-shaped rings. Each C-shaped ring includes a plurality of wedge-shaped blocks, and the plurality of wedge-shaped blocks are hinged. A spring is connected between the first wedge-shaped block and the last wedge-shaped block. Each C-shaped ring abuts against one of the chucks on the relative outer side between the two chucks.
[0006] Further, each chuck includes two semi-circular cards. One end of the two semi-circular cards is hinged, and the other end of the two semi-circular cards is detachably fixedly connected.
[0007] Further, one end of each distance rod is fixedly connected to one of the chucks, and the other end of each distance rod is screwed to the other chuck through two nuts, and the two nuts are placed on both sides of the chuck.
[0008] Further, the inner sides of the two chucks are inclined planes that extend outward between the two chucks.
[0009] The beneficial effects of the present utility model are as follows: The structure of the present utility model is simple. The C-shaped ring composed of multiple wedge-shaped blocks hinged together can be applicable to the butt joint of steel pipes with different pipe diameters within the inner diameter range of the chuck. Each wedge-shaped block of the C-shaped ring is in contact with the chuck and the steel pipe, which can stably fix the steel pipe. The structures of the chuck, the spacer rod, and the C-shaped ring are convenient to disassemble and assemble, flexible to use, and applicable to field construction. Description of the Drawings:
[0010] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0012] Figure 2 It is a right view of the present utility model.
[0013] In the figure: chuck 1, card 11, spacer rod 2, C-shaped ring 3, wedge-shaped block 31, spring 32, nut 4, steel pipe 5. Specific Embodiment:
[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0015] Combined with Figure 1-2 As shown, a pipe orifice butt joint device for steel pipe installation includes two circular chucks 1. Each chuck includes two semi-circular cards 11. One end of the two semi-circular cards 11 is hinged, and the other end of the two semi-circular cards 11 is fixedly connected through a mechanical lock to realize the locking of the chuck.
[0016] The two chucks 1 are connected by multiple spacer rods 2. One end of each spacer rod 2 is fixedly connected to one of the chucks 1, and the other end of each spacer rod 2 is screwed to the other chuck 1 through two nuts 4. The two nuts 4 are placed on both sides of the chuck 1 to realize the spacing and fixation between the two chucks 1.
[0017] It also includes two C-shaped rings 3. Each C-shaped ring 3 includes a plurality of wedge-shaped blocks 31. The plurality of wedge-shaped blocks 31 are hinged to each other. A spring 32 is connected between the first wedge-shaped block 31 and the last wedge-shaped block 31, enabling the C-shaped ring 3 to surround steel pipes 5 with different pipe diameters. Each C-shaped ring 3 abuts against one of the chucks 1 on the relatively outer side between the two chucks 1.
[0018] The inner ring of the chuck 1 is provided with an inclined surface that slopes outward between the two chucks 1, increasing the contact range between the chuck 1 and the C-shaped ring and improving the stability of the abutment between the chuck 1 and the C-shaped ring.
[0019] Working principle:
[0020] During use, each chuck 1 is sleeved on a steel pipe 5, and the two chucks 1 are fixed by a plurality of spacer rods 2. Each C-shaped ring 3 is inserted into the gap between one of the chucks 1 and a steel pipe 5 from the relatively outer side between the two chucks 1, ensuring that each wedge-shaped block 31 is in full contact with the inner ring of the chuck 1 and the outer wall of the steel pipe 5, achieving concentric docking of the two steel pipes 5. Loosen the nuts 4 on the relatively inner sides of the two chucks 1, adjust the nuts 4 on the relatively outer sides of the two chucks 1 to adjust the pipe orifices of the two steel pipes 5 to an appropriate distance, and tighten the nuts 4 on the relatively inner sides of the two chucks 1 to complete the docking of the two steel pipes 5. After welding is completed, take out the C-shaped ring 3 outward, remove one end of the spring 32, remove the C-shaped ring 3, unlock the mechanical locks of the two chucks 1, and remove the two chucks 1.
[0021] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
