Description

Technical Field

[0001] This utility model belongs to the field of steel pipe plugging technology, specifically relating to a steel pipe plugging tool. Background Technology

[0002] In current tooling for pressing steel pipe plugs into steel pipes, such as the improved structure for pressing manifold caps disclosed in CN203282157U, the entire tooling is arranged horizontally. During operation, the pipe fittings are placed horizontally, so the plugs aligned with the pipe openings are in a vertical position. In order to prevent the plugs from falling over, a special assembly for storing the plugs is required. For example, in CN203282157U, a capping fixture for pressing the caps needs to be connected to the end of the piston rod.

[0003] This application proposes a steel pipe sealing fixture that does not require a dedicated storage for the plug assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a steel pipe plugging tool to solve the technical problem that the current tooling for pressing steel pipe plugs into steel pipes is horizontally arranged and must rely on a special plug storage component.

[0005] To solve the above-mentioned technical problems, this utility model provides a steel pipe plugging tool, including: a positioning component, which is disposed on a base, wherein a positioning part is provided for inserting a plug, the plug being adapted to align with and be pressed by the pipe fitting after being inserted into the positioning part; the base is provided with a pressing head component, which is adapted to press and connect the plug with the pipe fitting.

[0006] Furthermore, the positioning component includes: a positioning block disposed on the base; the positioning part is a positioning groove located on the side wall of the positioning block, extending vertically or obliquely from the upper edge of the positioning block to the base, so that the pipe placed in the positioning groove presses down on the plug placed in the positioning groove by its own weight.

[0007] Furthermore, the lower wall of the positioning groove and the bottom of the positioning groove form a first plug placement area, so that the pipe fittings placed later into the positioning groove press down on the plugs placed in the first plug placement area.

[0008] Furthermore, the positioning groove extends from the upper edge of the positioning block to the lower edge of the positioning block, and the bottom of the positioning groove and the seat surface of the base form a second plug placement part, so that the pipe fitting that is later placed into the positioning groove presses down on the plug placed in the second plug placement part.

[0009] Furthermore, the pressure head assembly includes: a mounting base disposed on the base, and a linear actuator disposed on the mounting base, adapted to press and connect aligned plugs and fittings.

[0010] Furthermore, the mounting base is provided with a trigger switch, which is electrically connected to the linear actuator and is adapted to be triggered after the pipe fitting is in contact with the positioning groove to start the linear actuator.

[0011] Furthermore, the linear actuator is slidably connected to the mounting base and is adapted to be locked by a locking member after adjusting the distance from the positioning groove.

[0012] The beneficial effect of this utility model is that it aims to solve the technical problem that the current tooling for pressing steel pipe plugs into steel pipes, due to its horizontal arrangement, must rely on a special plug storage component. The positioning component of this steel pipe plugging tool is provided with a positioning part, which allows the subsequently inserted pipe fitting to press down the plug already placed in the positioning part by its own weight. In this way, the pipe fitting and the plug can be kept aligned until the pressing component presses the plug against the pipe fitting, eliminating the need for a special plug storage component.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments implemented by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Example like Figure 1 As shown, this utility model provides a steel pipe plugging fixture, including: a positioning component 100, which is disposed on a base 200, wherein a positioning part 110 is provided for inserting a plug. For ease of understanding, the plug is marked as 410 and the pipe fitting as 420 in the attached drawings. Figure 3 The plug is adapted to be aligned with the pipe fitting placed into the positioning part 110 and pressed down by the pipe fitting; the base 200 is provided with a pressing head assembly 300, which is adapted to press the plug against the pipe fitting and connect them.

[0017] The positioning component 100 of this steel pipe plugging tool is provided with a positioning part 110. The positioning part 110 allows the later-inserted pipe fitting to press down on the plug that has been placed in the positioning part 110 by its own weight. In this way, the pipe fitting and the plug can be kept aligned until the pressing head component 300 presses the plug against the pipe fitting, and no special plug storage component is needed.

[0018] like Figure 1 As shown, the positioning component 100 may include: a positioning block 120 disposed on the base 200; the positioning part 110 is a positioning groove 111 extending vertically or obliquely from the upper edge of the positioning block 120 towards the base 200 and located on the side wall of the positioning block 120, so that the pipe fitting placed in the positioning groove 111 presses down on the plug placed in the positioning groove 111 by its own weight. A schematic diagram of the positioning groove 111 extending vertically is shown in the attached diagram. Figures 1 to 4 At this time, the positioning groove 111 can be, but is not limited to, a U-shaped groove or a C-shaped groove. The pipe fitting placed in the positioning groove 111 can press down on the plug placed in the positioning groove 111 by its own weight. The pressing head assembly 300 is located directly above and facing the positioning groove 111. In addition, the positioning groove 111 can also extend at an angle to... Figure 1 For reference, including but not limited to when the length direction of the base 200 is taken as the front-back direction, the positioning groove 111 is tilted front-back. At this time, the positioning groove 111 is a groove that is deeper at the top and shallower at the bottom. The pipe fittings placed in the positioning groove 111 can also press down the plug placed in the positioning groove 111 by their own weight. The pressure head assembly 300 is located in the extension direction of the positioning groove 111 and is directly facing the positioning groove 111.

[0019] To ensure that the plug and fitting remain aligned.

[0020] like Figure 2 As shown, the lower wall of the positioning groove 111 can form a first plug placement part 131 with the bottom of the positioning groove 111. When the plug is put into the first plug placement part 131, it is placed on the lower wall of the positioning groove 111. The lower wall can be flat. At the same time, the bottom of the positioning groove 111 can be used as a limit to ensure that the plug with a flat bottom is placed in place, so that the pipe fittings that are put into the positioning groove 111 later press down on the plug placed in the first plug placement part 131.

[0021] like Figure 1 As shown, the positioning groove 111 can also extend from the upper edge of the positioning block 120 to the lower edge of the positioning block 120. The bottom of the positioning groove 111 and the seat surface of the base 200 form a second plug placement part 132. When the plug is put into the second plug placement part 132, it is placed on the seat surface of the base 200. The seat surface can be a plane. At the same time, the bottom of the positioning groove 111 can be used as a limit to ensure that the plug with a flat bottom is placed in place, so that the pipe fitting that is put into the positioning groove 111 later presses down on the plug placed in the second plug placement part 132.

[0022] like Figure 1 As shown, the pressure head assembly 300 may include: a mounting base 310 disposed on the base 200, and a linear actuator 320 disposed on the mounting base 310, adapted to press and connect aligned plugs and fittings. The linear actuator 320 may be, but is not limited to, a cylinder or an electric cylinder.

[0023] like Figure 1 and Figure 2 As shown, the mounting base 310 may be equipped with a trigger switch 330, which is electrically connected to the linear actuator 320, in conjunction with... Figure 3 The linear actuator 320 is triggered after the pipe fitting is in contact with the positioning groove 111. The trigger switch 330 may be, but is not limited to, a push switch, which is mounted above the positioning groove 111 via a bracket, and the horizontal distance between the push switch and the positioning groove 111 is such that the triggering part of the push switch can be triggered by the pipe fitting after the pipe fitting is fully in contact with the positioning groove 111.

[0024] The linear actuator 320 can be slidably connected to the mounting base 310 and is adapted to be locked by the locking member 340 after adjusting the distance from the positioning groove 111. Figure 4 As shown, the linear actuator 320 can be pre-installed on the linear actuator connecting plate 430. A strip-shaped through hole can be opened on the mounting base 310. The locking member 340 can be a screw. The locking member 340 passes through the strip-shaped through hole and connects to the screw hole on the linear actuator connecting plate 430, so that the linear actuator 320 can slide along the mounting base 310 according to the length of the pipe. After the position is adjusted, it is locked by the locking member 340.

[0025] like Figure 3 and Figure 4 As shown, the positioning block 120 and the mounting base 310 can be, but are not limited to, connected to the base 200 by screws.

[0026] In summary, the positioning component 100 of this steel pipe plugging fixture is provided with a positioning part 110. The positioning part 110 allows the subsequently inserted pipe fitting to press down on the plug already placed in the positioning part 110 by its own weight. In this way, the pipe fitting and the plug can be kept aligned until the pressing head component 300 presses the plug against the pipe fitting, and no special plug storage component is needed.
