Description

Technical Field

[0001] This utility model relates to the field of tee pipe processing technology, specifically a tee pipe processing device. Background Technology

[0002] A pipe fitting with three openings is called a tee. Tee fittings are widely used in pipeline networks for transporting liquids and gases. Depending on the medium being transported, tee fittings are made of materials such as cast iron, cast steel, cast copper, cast aluminum, plastic, and glass. Tee fittings are used to change the direction of fluid flow and can be used in water pipelines, oil pipelines, and pipelines for transporting various liquid chemical materials. They are mainly used in medical, water conservancy (water-saving irrigation, water supply and drainage), energy (oil, natural gas, nuclear industry), and construction engineering fields.

[0003] When using existing tapping equipment for T-joints, each joint of the T-joint needs to be tapped. Since the existing tapping equipment uses a one-way positioning fixture, after tapping one end of the T-joint, the T-joint needs to be rotated repeatedly to cooperate with the positioning fixture in order to achieve reverse tapping. Therefore, an improved device is needed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a three-way pipe processing device to solve the problems mentioned in the background art.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides an embodiment of a three-way pipe processing device, including a support device 3. A guide device 2 is fixedly installed at the front end of the top of the support device 3, and a positioning device 1 is fixedly installed at the rear end of the guide device 2. The positioning device 1 includes a threaded rod 4, a nut 5, a first three-way sleeve 6, a support frame 7, a second three-way sleeve 8, and a three-way pipe 9. The threaded rod 4 is symmetrically fixedly installed on the side end of the second three-way sleeve 8. The nut 5 is threadedly sleeved on the outer ring of the threaded rod 4. The support frame 7 is symmetrically fixedly installed on the side end of the first three-way sleeve 6. The three-way pipe 9 is slidably installed between the second three-way sleeve 8 and the first three-way sleeve 6. The support device 3 includes a tapping tool 16 and a support base 17. The tapping tool 16 is fixedly installed on the top end of the support base 17.

[0020] The guide device 2 includes a return spring 10, a plug rod 11, a positioning sleeve 12, a support shaft 13, a connecting side frame 14, and a vertical plate 15. The connecting side frame 14 is fixedly installed on one end of the support shaft 13. The support shaft 13 is rotatably installed inside the side end of the vertical plate 15. The positioning sleeve 12 is fixedly installed on the top of the other end of the support shaft 13. The return spring 10 is fixedly installed inside the positioning sleeve 12. The plug rod 11 is fixedly connected to the end of the return spring 10 away from the connecting side frame 14. A through hole adapted to the support shaft 13 is opened inside the side end of the vertical plate 15, so that the support shaft 13 can rotate inside the vertical plate 15.

[0021] The first tee sleeve 6 is connected to the connecting side frame 14 at the side end opposite to the second tee sleeve 8. The vertical plate 15 is fixedly installed at the top front end of the support base 17. The support frame 7 is slidably sleeved on the outer ring of the threaded rod 4, which can improve the docking accuracy of the first tee sleeve 6 and the second tee sleeve 8.

[0022] The vertical plate 15 has round holes at the top and both ends of its side end away from the connecting side frame 14. The insert rod 11 is inserted into the round holes on both sides and the top of the vertical plate 15 respectively, so that the tee tube 9 can be tapped at different angles.

[0023] The first tee sleeve 6 has symmetrical insertion holes on its side end near the second tee sleeve 8, which are adapted to the threaded rod 4, so that the threaded rod 4 can pass through the interior of the first tee sleeve 6.

[0024] The inner walls of the second tee sleeve 8 and the first tee sleeve 6 are fitted to the outer wall of the tee pipe 9, which can prevent the tee pipe 9 from shaking between the first tee sleeve 6 and the second tee sleeve 8.

[0025] Working principle: In use, first place the tee tube 9 inside the side end of the first tee sleeve 6 near the second tee sleeve 8 until the outer wall of the tee tube 9 is in contact with the inner wall of the side end of the first tee sleeve 6. Then move the second tee sleeve 8 towards the first tee sleeve 6 until the threaded rod 4 penetrates the inside of the support frame 7, so that the surfaces of the first tee sleeve 6 and the second tee sleeve 8 are in contact. After that, the nut 5 can be screwed on the threaded rod 4 until it is tightened with the support frame 7, thus fixing the tee tube 9 between the first tee sleeve 6 and the second tee sleeve 8. Then, the tapping tool 16 can be started to tap the center of the top of the tee tube 9. After that, the insertion rod 11 is pulled outward until it is removed from the insertion hole inside the side end of the vertical plate 15. Then, the support shaft 13 is rotated 90° so that the base hole of the side end of the tee tube 9 can be vertically aligned with the tapping tool 16. At the same time, when the support shaft 13 rotates 90°, The device aligns the insertion rod 11 with the insertion hole on the side of the vertical plate 15. Then, the insertion rod 11 is released, and the elasticity of the return spring 10 causes the insertion rod 11 to move and reset, allowing it to be inserted into the insertion hole inside the side of the vertical plate 15. This supports the T-tube 9 in a vertical position for tapping. The above steps can be repeated to rotate the base hole on the other side of the T-tube 9 to align with the tapper 16, allowing tapping of the top and sides of the T-tube 9. In use, the first T-tube sleeve 6 and the second T-tube sleeve 8 are positioned using a nut 5 and a threaded rod 4, stably restricting the T-tube 9 between them. Furthermore, after the support shaft 13 rotates 90° clockwise or counterclockwise, it aligns the base holes on both sides of the T-tube 9 with the tapper 16, facilitating quick and easy tapping of both sides of the T-tube 9 to complete the work.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
