Abstract
Description
Technical Field
[0001] The present application relates to the field of flange installation technology, and in particular to an installation tool for flange leveling and bolt sealing gaskets. Background Art
[0002] When connecting the process pipeline flanges, install bolts and gaskets. Use the pointed end of a crowbar to insert into the corresponding flange bolt holes to pry and adjust the concentricity of the screw holes, and then install all the flange bolts. Insert the flat head of the other end of the crowbar into the gap between the flanges, pry open a certain gap or distance, and then install the flange sealing gasket.
[0003] Using a crowbar to install flange bolts and sealing gaskets requires manpower to press, bend and pry. When the pipeline reaches a certain weight, the crowbar is likely to slip and deform, posing a safety hazard to people. There are also problems with the flatness of the bolt installation, the flushness of the flange, and the uniformity of the placement of the flange sealing gasket. Utility Model Content
[0004] In order to improve the problems of human safety hazards, flatness of bolt installation, flushness of flange, and uniformity of placement of flange sealing gaskets when installing flanges, the present application provides a flange leveling and bolt sealing gasket installation tool.
[0005] The present application provides a flange aligning and bolt sealing gasket installation tool that adopts the following technical solution:
[0006] A flange leveling and bolt sealing gasket installation tool, comprising: a main frame, a positioning pin, an internal threaded head, an adjusting screw and two parallel arm blocks, the main frame is provided with two mounting holes, the two parallel arm blocks correspond to the two mounting holes one by one, one end of the parallel arm block is fixed in the mounting hole, the positioning pin passes through the other end of one of the parallel arm blocks, the threaded hole of the flange and the other end of the other parallel arm block in sequence, the internal threaded head is arranged in the middle of the main frame, the adjusting screw is threadedly connected to the internal threaded head, and the end of the adjusting screw close to the flange is detachably connected with a flat head block or a flat head block.
[0007] The flange aligning and bolt sealing gasket installation tool provided in the embodiment of the present disclosure can achieve the following technical effects:
[0008] The ability to quickly and accurately install bolts and gaskets also helps to improve the flatness of flange connections and the quality of the connection after installation, while reducing the occurrence of human installation errors and the resulting safety hazards, thereby improving work quality and efficiency.
[0009] The above general description and the following description are exemplary and explanatory only and are not intended to limit the present application. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a structural schematic diagram of a flange aligning and bolt sealing gasket installation tool provided in an embodiment of the present application.
[0011] Figure 2 It is a structural schematic diagram of another flange aligning and bolt sealing gasket installation tool provided in an embodiment of the present application.
[0012] Explanation of the accompanying drawings: 1. flat head block; 2. internal thread head; 3. main frame; 4. adjusting screw; 5. parallel arm block; 6. mounting hole; 7. positioning pin; 8. threaded hole; 9. flat head block. DETAILED DESCRIPTION
[0013] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0014] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.
[0015] The following is combined with Figure 1-2 This application is described in further detail.
[0016] A flange leveling and bolt sealing gasket installation tool, comprising: a main frame 3, a positioning pin 7, an internal thread head 2, an adjusting screw 4 and two parallel arm blocks 5, the main frame 3 is provided with two mounting holes 6, the two parallel arm blocks 5 correspond to the two mounting holes 6 respectively, one end of the parallel arm block 5 is fixed in the mounting hole 6, the positioning pin 7 passes through the other end of one of the parallel arm blocks 5, the threaded hole 8 of the flange and the other end of the other parallel arm block 5 in sequence, the internal thread head 2 is arranged in the middle of the main frame 3, the adjusting screw 4 is threadedly connected to the internal thread head 2, and the end of the adjusting screw 4 close to the flange is detachably connected with a flat head block 1 or a flat head block 9.
[0017] The positioning pin 7 is passed through the flange, so as to position the threaded hole 8 of the flange. When a flat block is provided on the adjusting screw 4, the adjusting screw 4 is rotated so that the flat head is close to the flange and the flange is spread open, thereby leaving space required for installing the flange gasket, which is convenient for installing the gasket; when a flat head block 9 is provided on the adjusting screw 4, the adjusting screw 4 is rotated so that the flat head block 9 is close to the flange and pressed against the side wall of the flange, thereby adjusting the neatness of the outer edge of the flange and the concentricity of the bolt hole, which is convenient for installing the bolt.
[0018] The above device can quickly and accurately install bolts and gaskets, and also help to improve the flatness of the flange connection and the quality after installation. At the same time, it reduces the occurrence of human installation errors and the resulting safety hazards, and improves the quality and efficiency of the work.
[0019] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
