Description

Technical Field

[0001] The utility model relates to the technical field of Glyer ring tools, in particular to a tool for removing a built-in Glyer ring. Background Art

[0002] The internal Glyd ring is coaxially mounted on the inner wall of the flange pipe. Due to space limitations and the fact that the Glyd ring fits tightly into the sealing groove of the inner ring of the flange pipe, using common tools to pry out the Glyd ring or performing destructive removal is not only inefficient but also causes damage to the inner wall of the flange pipe. Summary of the invention

[0003] The technical problem to be solved by the utility model is that the removal efficiency is low and the inner ring of the flange is easily damaged.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a built-in grid ring removal tool, including a mounting rod, a material removal rod rotatably connected to one end of the mounting rod and a top block threadedly connected to the other end of the mounting rod, the top block is L-shaped, and the end wall of the flange connection end is accommodated in the gap between the movable end of the top block and the mounting rod, a torsion spring is arranged on the rotating shaft between the mounting rod and the material removal rod, and the bottom end of the material removal rod is acted upon by the torsion spring toward the direction of the mounting rod, and a top cone is threadedly connected to the bottom end of the material removal rod.

[0005] Preferably, two mutually perpendicular sections of the material taking rod and the top block are both threadedly connected with tightening bolts.

[0006] Preferably, the contact ends of the tightening bolt and the flange are both provided with connecting tightening teeth, and the tightening teeth are truncated cone-shaped.

[0007] Preferably, a connecting pipe is fixedly provided at the bottom end of the material taking rod, the middle part of the top cone is threadedly connected to the connecting pipe, and a spiral cone head is provided at one end of the top cone facing the flange.

[0008] Preferably, a handle is provided at the top of the material taking rod.

[0009] The utility model provides an internal grid ring extractor, which abuts against the side wall of the flange end through a top block and acts on a material taking rod through a torsion spring, so that the taking tool is stably clamped on the end of the flange, and then the top cone is spirally inserted into the grid ring, and then the material taking rod is rotated to bring out part of the grid ring, and the grid ring can be completely taken out by operating around the grid ring for multiple times, thereby improving the efficiency of taking out the internal grid ring and avoiding damage to the flange. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0011] Figure 1 It is a schematic diagram of the internal structure of an embodiment of the utility model.

[0012] In the figure: 1. flange; 2. grid ring; 3. mounting rod; 4. material removal rod; 5. top block; 6. tightening bolt; 7. connecting pipe; 8. top cone; 9. torsion spring. DETAILED DESCRIPTION

[0013] like Figure 1 The utility model provides a built-in grid ring removal tool, comprising a mounting rod 3, a material removal rod 4 rotatably connected to one end of the mounting rod 3, and a top block 5 threadedly connected to the other end of the mounting rod 3, the top block 5 is L-shaped, and the end wall of the end connected to the flange 1 is accommodated in the gap between the movable end of the top block 5 and the mounting rod 3, a torsion spring 9 is arranged on the rotating shaft between the mounting rod 3 and the material removal rod 4, and the bottom end of the material removal rod 4 is acted by the torsion spring 9 toward the mounting rod 3, and the bottom end of the material removal rod 4 is threadedly connected with a top cone 8.

[0014] By rotating the top block 5 to be in the same plane with the feeding rod 4, manually rotating the other end of the feeding rod 4, so that the gap between the bottom end of the feeding rod 4 and the top block 5 is increased, the end of the flange 1 is inserted between the top block 5 and the mounting rod 3, and then the position of the feeding rod 4 is automatically restored with the action of the torsion spring 9, so that the top cone 8 on the feeding rod 4 is located on one side of the grid ring 2, and the top cone 8 is rotated so that the sharp end of the top cone 8 is inserted into the grid ring 2, and then the feeding rod 4 is manually rotated so that the feeding rod 4 brings part of the grid ring 2 out of the sealing groove during the rotation.

[0015] Then, according to the tightness of the connection of other parts of the grid ring 2, choose whether to use a removal tool to pull out part of the grid ring 2 at other parts of the grid ring 2 or use a pry bar to pry out the loose grid ring 2.

[0016] like Figure 1 As shown, in order to ensure the stability of the clamping flange of the Gray Ring removal tool, the two perpendicular sections of the material removal rod 4 and the top block 5 are threadedly connected with a tightening bolt 6. After the end of the flange is inserted between the material removal rod 4 and the top block 5, the tightening bolt 6 is rotated to contact the flange 1, and the removal tool is bitten on the flange 1.

[0017] As a preferred embodiment of the utility model, in order to further improve the clamping stability of the extraction tool, the contact ends of the clamping bolt 6 and the flange 1 are both provided with connecting clamping teeth, and the clamping teeth are truncated cone-shaped. By reducing the contact area and increasing the pressure, the extraction tool is clamped at the end of the flange 1, which is convenient for reducing the shaking of the extraction tool when the top cone 8 is rotated.

[0018] like Figure 1As shown, in order to realize the installation of the top cone 8. The bottom end of the material taking rod 4 is fixedly provided with a connecting pipe 7, the middle part of the top cone 8 is threadedly connected to the connecting pipe 7, and the end of the top cone 8 facing the flange 1 is provided with a spiral cone head. The outer diameter of the spiral cone head at the end of the top cone 8 is smaller than the outer diameter of the middle part of the top cone 8, and the other end of the top cone 8 is vertically connected with a handle to facilitate the staff to rotate the top cone 8.

[0019] like Figure 1 As shown, in order to facilitate the staff to rotate the material taking rod 4, a handle is provided at the top of the material taking rod 4.
