Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Like elements in the various figures are denoted by the same or similar reference numerals. For purposes of clarity, the various features in the drawings are not necessarily drawn to scale.
As shown in fig. 1 and 2, the present application provides a pipe orifice deformation prevention device, comprising: the ring sleeve 1 is used for being sleeved at the pipe orifice of the pipeline 6, and an opening is formed in the ring sleeve 1; the connecting piece 4 is connected to the opening of the ring sleeve 1 and used for fastening the ring sleeve 1; the top support device is arranged on the pipe orifice and in the ring sleeve 1, the top is contacted on the inner wall of the ring sleeve 1, and the length of the top support device in the radial direction of the ring sleeve 1 is adjustable.
The utility model provides a pipeline mouth of pipe anti-deformation device's theory of operation is: the pipe orifice of the pipeline 6 is fixed and formed through the ring sleeve 1, and the pipe orifice of the pipeline 6 is supported towards the outside in the ring sleeve 1 by using a jacking device, so that the problem that the pipe orifice deforms under the action of external force is prevented.
In this embodiment, the ring sleeve 1 is a double-layer ring structure, axial ends of the double-layer ring structure are connected to each other, and the other end of the double-layer ring structure and the inside of the ring sleeve 1 are provided with mutually communicated ring cavities for installing the pipe orifices of the pipelines 6. When the ring sleeve 1 is installed, one end of the pipe orifice of the pipeline 6 can be coaxially inserted into the ring cavity of the ring sleeve 1, and then the ring sleeve 1 is fastened through the connecting piece 4 on the ring sleeve 1 to prevent the ring sleeve 1 from being separated from the pipe orifice of the pipeline 6.
In this embodiment, the ring sleeve 1 is a structural member made of a steel plate and formed by bending, and the bending forming operation is simple, so that the number of connecting parts is reduced, and the structure is more stable. It will be appreciated that it is also possible to add stiffening ribs to the outer wall of the collar 1 to increase the structural strength of the collar 1.
In this embodiment, the two ends of the opening of the ring sleeve 1 are respectively connected with a right-handed nut and a left-handed nut, and the thread turning directions of the right-handed nut and the left-handed nut are opposite. The connecting piece 4 is a stud bolt, and a hexagonal bolt head is connected to the axial middle part of the stud bolt. The stud is arranged between the right-hand nut and the left-hand nut and is respectively in threaded connection with the right-hand nut and the left-hand nut. It should be understood that the hexagonal bolt head provided at the center of the stud bolt facilitates the screwing of the stud bolt, and that the stud bolt is screwed in the same direction, and since the screw threads of the right-hand nut and the left-hand nut are opposite, the right-hand nut and the left-hand nut are moved toward or away from each other when the stud bolt is screwed, thereby fastening the collar 1 and loosening the collar 1.
In this embodiment, the jacking device includes: the outer wall of the ring pipe 5 is connected with at least three nuts, and the nuts are uniformly distributed along the circumferential direction of the ring pipe 5; the first end of each support rod 3 is provided with an external thread part, the external thread part of each support rod 3 is in threaded connection with each nut on the ring pipe 5, and the support rods 3 are screwed to enable the support rods 3 to be tightly pressed against the inner wall of the ring sleeve 1, so that the support rods 3 support the pipe openings of the pipelines 6.
As shown in fig. 1, by screwing each support rod 3, a relative displacement in the axial direction is generated between each nut on the ring pipe 5 and its corresponding support rod 3, because each nut and its corresponding support rod 3 are uniformly distributed in the circumferential direction of the ring pipe 5, when the rotation angles of each support rod 3 are consistent, the force received by the ring pipe 5 is uniform and acts on the ring sleeve 1, respectively, thereby realizing that the support rods 3 are pressed against the inner wall of the ring sleeve 1 by screwing the support rods 3, and ensuring the shape of the ring sleeve 1, i.e. the shape of the orifice of the pipeline 6.

The four nuts are arranged, namely, each nut is connected with one supporting rod 3 respectively, so that the supporting distribution of each supporting rod 3 to the ring sleeve 1 is more uniform, and the shape of the ring sleeve 1 is protected more effectively. It can be understood that the ring sleeve 1 not only maintains the shape of the pipe orifice of the pipeline 6, but also ensures that the pipe orifice of the pipeline 6 is damaged by the support rods 3.
5, 6 or 8 nuts can be uniformly distributed on the outer wall of the ring pipe 5, and each nut is correspondingly connected with one support rod 3.
In this embodiment, each nut is welded to the collar 5, so that the welding is more stable.
In the present embodiment, the second end of each support rod 3 is provided with an internal thread, and the internal thread extends along the axial direction of the support rod 3.
In this embodiment, each of the support rods 3 further includes a tightening bolt 2, the tightening bolt 2 is screwed to the second end of the corresponding support rod 3, and the end of the tightening bolt 2 is used for contacting the inner wall of the ring sleeve 1. Through the puller bolt 2 that sets up, can increase the length that 3 axials of bracing piece extend, increased and twisted the variable of length soon, one of them variable is the threaded connection between bracing piece 3 and the nut, and the second variable is the threaded connection between bracing piece 3 and the puller bolt 2.
In an optional embodiment of the present application, four nuts are uniformly welded on the inner wall surface of the ring sleeve 1 along the circumferential direction thereof, and the four nuts can be simultaneously screwed with the tightening bolts 2, so that the tightening bolts 2 are respectively screwed with the nuts on the inner wall surface of the ring sleeve 1 and the second end of the support rod 3, thereby realizing the limitation of the ring sleeve 1 in the radial direction and more effectively avoiding the deformation of the pipe orifice of the pipeline 6.
The application provides a pipeline mouth of pipe anti-deformation device can overlap on the mouth of pipe of pipeline 6 through ring cover 1, plays the effect of maintaining the shape to the 6 mouths of pipe of pipeline to and play and avoid receiving the damage that collides with and cause. The supporting device can be adjustably supported on the inner wall surface of the ring sleeve 1, so that the pipeline 6 is prevented from deforming when being extruded. Thereby reduced 6 mouths of pipe's not damaged butt joints of pipeline, improved 6 efficiency of construction of pipeline, guaranteed the welding quality of 6 butt joints of pipeline.
