Description

Technical Field

[0001] The utility model relates to the technical field of PE gas pipeline welding construction, in particular to a multi-purpose arc scraper for scraping the surface of PE pipes. Background Art

[0002] According to the requirements of PE pipe electric fusion welding, the surface of the pipe needs to be scraped during electric fusion welding to ensure the welding quality. However, the bottom cannot be directly inspected with the naked eye during scraping. The current means can only be observed with the help of a mirror and then scraped with a scraper. The blade used is linear and can only make point contact with the curved pipe surface, which will result in quality problems such as inability to operate continuously, relatively low operating efficiency, and an uneven scraped surface. Utility Model Content

[0003] In order to overcome the deficiencies in the prior art, the utility model provides a multi-purpose arc scraper for scraping the surface of a PE pipe. The multi-purpose arc scraper of the utility model is used to scrape the surface of the PE pipe, thereby ensuring that the scraped surface of the PE pipe is smooth, thereby ensuring the quality of the PE pipe.

[0004] The technical solution of the utility model to solve the above technical problems is:

[0005] A multi-purpose arc-shaped scraper for scraping the surface of PE pipes, comprising a tool holder, a scraping blade arranged on the tool holder and a glass mirror, wherein the tool holder comprises a handle portion and a mounting portion connected to the handle portion; the mounting portion is provided with a lens mounting position and a tool mounting position, the glass mirror is mounted on the lens mounting position; the scraping blade is mounted on the tool mounting position; the blade edge of the scraping blade is arc-shaped.

[0006] Preferably, the curvature of the blade edge of the scraping blade is the same as the curvature of the outer surface of the PE pipe.

[0007] Preferably, the lens mounting position is provided with a clamping edge for clamping the glass mirror, the clamping edge is arranged on both sides of the glass mirror, and includes a first clamping edge and a second clamping edge arranged in parallel, and the first clamping edge and the second clamping edge both extend along the length direction of the tool holder.

[0008] Preferably, the glass mirror is fixed at the lens mounting position by a rubber clip.

[0009] Preferably, the scraping blade is fixed to the tool mounting position by means of screws.

[0010] Preferably, a clip layer is provided on the blade seat of the scraping blade, and the length direction of the clip layer is perpendicular to the length directions of the first clamping edge and the second clamping edge.

[0011] Preferably, the outer wall of the glass mirror includes a shock-absorbing layer; the shock-absorbing layer is a sponge layer.

[0012] Preferably, the handle portion is a flat structure and is provided with an anti-slip portion.

[0013] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0014] 1. The utility model is a multi-purpose arc scraper for scraping the surface of PE pipes. It is combined with a glass mirror and a scraping blade. It can be used to inspect the surface quality of the bottom of the outer pipe and the upper part of the inner wall, and can also scrape the outer surface, thereby realizing the quality inspection and continuous scraping operation of the surface of the PE pipe.

[0015] 2. The utility model of the multi-purpose arc scraper for scraping the surface of PE pipes changes the blade of the scraper blade from a linear shape to an arc shape, so that the contact between the scraper blade and the outer surface of the PE pipe is contact, so that the scraping area each time is larger, which is not only conducive to improving the processing efficiency (i.e. reducing the inspection and scraping pause time during the operation process), but also conducive to improving the scraping quality of the PE pipe surface. In addition, the surface scraped by the arc blade is smoother than that of the linear blade, which is conducive to ensuring the quality of electric fusion welding.

[0016] 3. The multi-purpose arc scraper for scraping the surface of PE pipes of the utility model is easy to maintain and assemble. In addition, the multi-purpose arc scraper of the utility model is a purely manual device. If a part is damaged, it can be directly replaced without involving electric devices such as motors. The operation risk is relatively low, and no special safety measures are required during storage. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0023] See also Figure 1-Figure 4 The utility model discloses a multi-purpose arc scraper for scraping the surface of PE pipe, comprising a knife holder 1, a scraping blade 4 (made of alloy material) arranged on the knife holder 1 and a glass mirror 3, wherein the knife holder 1 comprises a handle portion and a mounting portion connected to the handle portion; the mounting portion is provided with a lens mounting position and a tool mounting position, the glass mirror 3 is mounted on the lens mounting position; the scraping blade 4 is mounted on the tool mounting position; the scraping blade 4 is arc-shaped from the blade edge 401, and the curvature of the blade edge 401 of the scraping blade 4 is the same as the curvature of the outer surface of the PE pipe.

[0024] In this embodiment, the tool holder 1 can be made of PE material, the handle is round and the gripping part has patterns (i.e. the anti-slip part), the head of the tool holder 1 is reserved for installing the glass mirror 3, the tool, and the bolt hole, the reserved position of the tool (tool installation position) is lower than the reserved position for installing the glass mirror 3 (lens installation position), the bolt hole is used to fix the scraping blade 4, and all the intersection angles of the contact surfaces are chamfered and smoothly transitioned to reduce stress.
