Description

Technical Field

[0001] The invention relates to a pipe butt joint construction method and belongs to the technical field of pipeline butt joint construction. Background Art

[0002] In the construction of production bases for chemical drugs and other products, in order to transport fluid raw materials, pipelines for transporting fluid raw materials need to be buried during the construction of the production base. Before the pipelines are buried, they need to be connected by hot-melt connection through pipe sleeves.

[0003] When the pipe sleeve 2 is connected to the pipe mouth of the pipe 1, the prior art is to use a pad 3 to pad one end of the pipe sleeve 2 and knock it into the pipe mouth of the pipe 1, such as Figure 3 As shown, although the operator can transmit the knocking force through the pads 3 to knock the pipe sleeve 2 into the pipe mouth of the pipe 1, when the pads 3 are placed on the pipe sleeve 2, it is difficult for the pads 3 to be symmetrically located at the four points A, B, C, and D of the pipe mouth of the pipe 1 to transmit the knocking force. When the pads 3 are not located at the four points A, B, C, and D of the pipe mouth of the pipe 1 to knock the pipe sleeve 2, there is a problem that the deformation and insertion process of the pipe sleeve 2 will not be uniform to achieve a quick and complete connection with the pipe mouth of the pipe 1. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a pipe opening butt joint construction method.

[0005] The present invention is achieved through the following technical solutions.

[0006] The present invention provides a pipe orifice butt joint construction method, comprising:

[0007] The sleeve is evenly deformed when four wood blocks are struck at four points A, B, C, and D vertically symmetrically at the pipe opening to achieve the sleeve insertion process.

[0008] The nesting process is further as follows:

[0009] The four skids of the pipe opening butt-jointing force-applying fixture are symmetrically installed at the four points A, B, C, and D of the pipe opening through the telescopic frame;

[0010] Four block woods are struck at four points A, B, C and D which are vertically symmetrical at the pipe opening, so that the pipe sleeve is evenly deformed and can be inserted into the pipe opening.

[0011] The pipe mouth docking force applying tooling comprises:

[0012] skids;

[0013] The telescopic frame has four pads symmetrically installed on the telescopic frame so as to be symmetrically located at the four points A, B, C and D of the pipe opening.

[0014] The telescopic frame is a fixed frame or a variable diameter telescopic frame.

[0015] The variable diameter telescopic frame includes two double-ended telescopic rods, the four ends of which can be extended to drive four pads to realize the sleeve of pipes of different diameters on the pipe openings of different diameters. The non-extensible sections in the middle of the two double-ended telescopic rods are fixed to each other, and the telescopic sections at the ends of the two double-ended telescopic rods are used to support the four pads at four points A, B, C, and D that are vertically symmetrical at the pipe openings.

[0016] It also includes a support plate fixedly mounted on the telescopic end of the double-ended telescopic rod, the support plate having a T-shaped slide groove;

[0017] The sliding block is slidably matched with the T-shaped sliding groove of the support plate, and a T-shaped sliding rail is provided on the sliding block and is slidably matched with the T-shaped sliding groove of the support plate.

[0018] The sliding block is fixedly connected to the sleeper.

[0019] The block has a stepped surface which is clamped with the pipe sleeve.

[0020] A support rod is hinged on the support plate, and the middle part of the support rod can be reset and installed on the support plate through an elastic member that can provide elastic force; one end of the support rod is rotatably hinged to the support plate through an axis hinge, and the other end of the support rod is equipped with a roller that can roll with the inner wall of the pipe. The roller pulls the support rod through the elastic member to roll and press it against the inner wall of the pipe and then press it against the outer diameter surface of the pipe sleeve in combination with the step surface of the pad.

[0021] The elastic member can be a spring or an elastic rubber body to provide elastic force.

[0022] The beneficial effect of the present invention is that the four block woods are vertically symmetrical at the four points A, B, C, and D at the pipe orifice, and then when they are knocked, the pipe sleeve is ensured to be uniformly deformed to achieve the sleeve-in process, thereby ensuring that the pipe sleeve can be quickly and completely sleeved with the pipe orifice, solving the problem that the pipe sleeve deformation and sleeve-in process are not uniform to achieve quick and complete sleeve connection with the pipe orifice.

[0027] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0028] like Figures 1 to 2 shown.

[0029] A pipe joint force-applying tool of the present application includes:

[0030] four skids 3;

[0031] Four skids 3 are symmetrically installed at four points A, B, C, and D symmetrically at the pipe opening of the pipe 1 through a telescopic frame 4;

[0032] The telescopic frame 4 can be a fixed frame or a variable-diameter telescopic frame. When it is a variable-diameter telescopic frame, it includes two double-headed telescopic rods 41. The double-headed telescopic rods 41 can be telescoped to drive the four skids 3 to achieve the installation of different diameter pipe sleeves 2 on the pipe openings of different diameters of the pipe 1. The non-telescopic sections in the middle of the two double-headed telescopic rods 41 are fixed to each other, and the telescopic sections at the ends of the two double-headed telescopic rods 41 are used to support the four skids 3 at four points A, B, C, and D that are vertically symmetrical at the pipe opening of the pipe 1.

[0033] It also includes a support plate 51 fixedly mounted on the telescopic end of the double-ended telescopic rod 41, and the support plate 51 has a T-shaped slide groove;

[0034] A sliding block 52 slidably engaged with the T-shaped slide groove of the support plate 51, wherein the sliding block 52 has a T-shaped slide rail slidably engaged with the T-shaped slide groove of the support plate 51;

[0035] The sliding block 52 is fixed to the block 3 by bolts or fixedly connected as one piece.

[0036] When the knocking sliding block 52 is transmitted to the pad 3, the T-shaped slide rail of the sliding block 52 slides with the T-shaped slide groove of the support plate 51 to realize static guidance; the four ends of the two double-headed telescopic rods 41 are fixed with support plates 51, and four pads 3 are installed on the four support plates 51 through the sliding blocks 52, so that the four pads 3 are supported at the four points A, B, C, and D of the pipe mouth of the pipe 1, ensuring that the pads 3 are symmetrical at the four points A, B, C, and D of the pipe mouth of the pipe 1 to transmit the knocking force, and when the pads 3 knock the pipe sleeve 2 at the four points A, B, C, and D of the pipe mouth of the pipe 1, it is ensured that the pipe sleeve 2 is uniformly deformed to realize the sleeve-in process, thereby ensuring that the pipe sleeve 2 can be quickly and completely sleeved with the pipe mouth of the pipe 1, solving the problem that the deformation and sleeve-in process of the pipe sleeve 2 is not uniform to achieve quick and complete sleeve connection with the pipe mouth of the pipe 1.

[0037] The described pad 3 has a stepped surface that is engaged with the pipe sleeve 2; a support rod 53 is hinged on the support plate 51, and the middle part of the support rod 53 can be reset and installed on the support plate 51 through an elastic member 54 that can provide elastic force. The elastic member 54 can be composed of a spring or an elastic rubber body to provide elastic force; one end of the support rod 53 is rotatably hinged to the support plate 51 through an axial hinge, and the other end of the support rod 53 is equipped with a roller 55 that can roll with the inner wall of the pipe 1. The roller 55 pulls the support rod 53 through the elastic member 54 to roll and press on the inner wall of the pipe 1 and then combine with the stepped surface of the pad 3 to press on the outer diameter surface of the pipe sleeve 2, so that the pad 3 provides axial guidance when being struck.

[0038] A pipe joint construction method of the present application includes:

[0039] Four skids 3 of the pipe opening butt-jointing force-applying fixture are symmetrically installed at four points A, B, C, and D of the pipe opening of the pipeline 1 through a telescopic frame 4;

[0040] Four blocks 3 are struck at four points A, B, C, and D of the pipe opening of the pipe 1 so that the pipe sleeve 2 is uniformly deformed and the pipe sleeve is inserted into the pipe opening of the pipe 1.

[0041] Because the four block woods 3 are placed vertically symmetrically at points A, B, C, and D at the mouth of the pipe 1 through the telescopic frame 4, and then the pipe sleeve 2 is evenly deformed to achieve the sleeve-in process when it is knocked, it is ensured that the pipe sleeve 2 can be quickly and completely sleeved with the pipe mouth of the pipe 1, which solves the problem that the pipe sleeve 2 will not be evenly deformed and sleeved to achieve quick and complete sleeve connection with the pipe mouth of the pipe 1 during the sleeve-in process.
