Description

Technical Field

[0001] This utility model relates to the technical field of flange and pipe assembly, specifically to a horizontal eye and vertical eye alignment auxiliary level gauge clamp for vertical fixed flange assembly. Background Technology

[0002] A flange connection is a mechanical structure that enables a detachable connection between pipes or equipment using a combination of flanges, gaskets, and bolts. It is suitable for sealing requirements under high temperature and high pressure conditions. Due to its ease of disassembly, high strength, and good sealing performance, flange connections are widely used in industrial pipelines and the petroleum and chemical industries. Flange installation requires that the pipe and flange be concentric on the same axis, the pipe center be perpendicular to the flange sealing surface at a 90° angle, and the flange bolts on the pipe be aligned to ensure accurate installation.

[0003] In actual prefabrication operations, the workers' work attitude and skill level often lead to quality and accuracy issues in flange assembly, causing difficulties for subsequent installation or potential quality problems such as incomplete sealing. In traditional vertical fixed flange prefabrication, one person holds a spirit level, closely aligning it with the flange bolt holes. They must pay attention to the position of water droplets on the spirit level during alignment, as well as the relative position of the spirit level and the flange bolt holes, and the gap between the flange and the pipe and the misalignment of the pipe wall. Assembling a single flange requires a high degree of concentration, often requiring multiple people to complete the assembly. This process is labor-intensive, cumbersome, produces inconsistent quality, and poses certain safety hazards.

[0004] In order to improve the quality of flange prefabrication assembly, the development of this type of tooling fixture is of great significance in terms of simplifying operation procedures, reducing labor intensity, and eliminating safety and quality hazards. Utility Model Content

[0005] The main purpose of this utility model is to provide a vertical fixed flange assembly horizontal eye and vertical eye alignment auxiliary level gauge clamp that can improve the quality and efficiency of flange and pipe assembly.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: The vertical fixed flange assembly includes a level gauge clamp for aligning horizontal and vertical eyepieces. It comprises two positioning components that slide and engage with a clamping strip. A level gauge is magnetically connected to the clamping strip. Each positioning component includes a bolt. The bolt nut has a first conical surface machined at the end facing the bolt shank. A sleeve is fitted onto the bolt shank, and a second conical surface is machined at the end facing the bolt nut. The opposite ends of the first and second conical surfaces can be inserted into the mounting holes of the flange. A nut is threaded onto the bolt shank. A groove is provided on the outer side of the sleeve, and the clamping strip slides and engages in the groove.

[0007] Specifically, the slot is a dovetail slot.

[0008] Specifically, the cross-section of the card strip is trapezoidal.

[0009] Specifically, a sliding damping mechanism is provided between the card strip and the card slot.

[0010] Specifically, the nut is a wing nut.

[0011] Specifically, a washer is fitted onto the bolt shank between the nut and the sleeve.

[0012] Specifically, a magnet is fixed inside the lower end of the level, and the magnet magnetically attracts the clip and stably connects the level to the clip.

[0013] Specifically, the inner edge of the sleeve contacts the outer edge of the bolt shank.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. With the aid of a spirit level, the flange can be quickly adjusted to a horizontal position. When aligning the flange, simply rotate the flange to make the spirit level and then assemble it. This simplifies the traditional flange assembly process, reduces the time and error of manual adjustment, and ensures that the flange and pipeline are precisely aligned.

[0015] 2. The first and second conical surfaces of the positioning components ensure that the bolts are concentric with the mounting holes, preventing the mounting holes from shifting. At the same time, the structure of the locking strip and the slot provides mechanical locking, and the level ruler is attracted to the locking strip by a magnet, which enhances the overall stability and prevents loosening or slippage during assembly.

[0016] 3. The wing nut design makes it easy to tighten or loosen manually and quickly; the sliding engagement of the clip and slot allows for flexible position adjustment without additional tools; the magnetic connection of the level simplifies the installation and disassembly process and improves the convenience of on-site operation.

[0017] 4. Sliding damping is provided between the card strip and the card slot to effectively prevent the card strip from automatically falling off or shifting during the assembly process, ensuring that the level and the clamp remain reliably fixed when the flange is adjusted (such as by rotation or pressure application), thereby improving overall safety and durability.

[0018] 5. This clamp can be flexibly used for vertical and horizontal flange alignment. By adjusting the installation position of the positioning components, it can meet the needs of different flange assembly, thus enhancing the practicality and versatility of the technology.

[0019] 6. It is easier to operate in practical applications, eliminating the need to multitask, such as looking at the position of the water droplets on the level and the relative position of the level and the flange bolt holes. This precise operation significantly improves the assembly quality.

[0020] 7. When assembling flanges, the operation process is easy to master, which can save assembly time, significantly improve the output efficiency, and reduce labor intensity.

[0021] 8. It can be used for flange assemblies of various specifications, making it more widely applicable. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1: Refer to Figures 1-4 As shown, the vertical fixed flange assembly includes a level gauge clamp for aligning horizontal and vertical eyepieces. It comprises two positioning components that slide and engage with the clamping strip 5. A level gauge 6 is magnetically connected to the clamping strip 5. Specifically, a magnet is fixed inside the lower end of the level gauge 6, and the magnet magnetically attracts the clamping strip 5, stably connecting the level gauge 6 to the clamping strip 5.

[0030] The positioning assembly includes a bolt 2. The nut of the bolt 2 has a first conical surface 8 machined on the end facing the bolt 2 shank. A sleeve 3 is fitted on the bolt 2 shank. The inner edge of the sleeve 3 contacts the outer edge of the bolt 2 shank. The end of the sleeve 3 facing the nut of the bolt 2 has a second conical surface 9 machined. The opposite ends of the first conical surface 8 and the second conical surface 9 can be inserted into the mounting hole of the flange 1.

[0031] A nut 4 is threaded onto the shank of bolt 2. A washer 10 is fitted onto the shank of bolt 2 between the nut 4 and the sleeve 3. The nut 4 is a wing nut.

[0032] A groove 7 is provided on the outer side of the sleeve 3, and the retaining strip 5 is slidably engaged in the groove 7. Sliding damping is provided between the retaining strip 5 and the groove 7. Specifically, the groove 7 is a dovetail groove, and the cross-section of the retaining strip 5 is trapezoidal.

[0033] like Figure 1 and Figure 2 As shown, when flange 1 needs to be aligned vertically, two bolts 2 are inserted through the two mounting holes of flange 1, so that the portion of flange 1 above the two bolts 2 has a mounting hole. Then, two sleeves 3 are respectively fitted onto the shanks of the two bolts 2, two gaskets 10 are installed onto the shanks of the two bolts 2, and two nuts 4 are respectively threaded onto the shanks of the two bolts 2. This allows the retaining strip 5 to slide and engage in the retaining grooves 7 of the two sleeves 3, and the spirit level 6 is magnetically attached to the upper end of the retaining strip 5.

[0034] Rotate nut 4 to tighten sleeve 3. The opposite ends of the first conical surface 8 and the second conical surface 9 are inserted into the mounting hole where bolt 2 is located. After the first conical surface 8 and the second conical surface 9 are tightly against flange 1, bolt 2 is concentric with the mounting hole where it is located.

[0035] Then, rotate flange 1 to keep the level gauge 6 horizontal before assembling flange 1 with the pipe.

[0036] like Figure 5 As shown, when flange 1 needs to be aligned, the two positioning components are installed in the two adjacent mounting holes on flange 1. After the level 6 is kept horizontal, flange 1 can be assembled with the pipeline.

[0037] Example 2: Based on Example 1, a sliding damping mechanism is provided between the clamping strip 5 and the clamping groove 7. By providing sliding damping between the clamping strip 5 and the clamping groove 7, the clamping strip 5 can be prevented from automatically separating from the sleeve 3, and the stability of the clamping strip 5 and the level 6 can be guaranteed during the assembly of the flange 1 and the pipe.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
