Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical installation, and more specifically, particularly to a concentric positioning installation device for auxiliary wall-penetrating pipeline sleeves. Background Art

[0002] In the process of building mechanical and electrical installation, casing is often used to facilitate the installation of pipes. The traditional installation method is to place the pipe directly in the inner cavity of the casing, which involves a large number of different professional pipes passing through walls and floor casings, such as exterior wall flexible casing, indoor secondary masonry wall casing, indoor floor casing, etc. If the casing is not concentric with the internal pipe, the horizontality and verticality are inconsistent, it will affect whether the pipe penetration through the wall is evenly sealed, and the verticality and horizontality deviations of the pipe installation are serious, affecting the construction quality and causing slow construction progress.

[0003] Announcement No. CN212004609U discloses a sleeve positioning device for a through-wall pipe, comprising: a positioning ring that is sleeved on the through-wall pipe and fixed to the through-wall pipe in a detachable manner; a plurality of limit frames of equal length, one end of the limit frame is vertically fixed to the surface of the positioning ring and the extension line passes through the center of the positioning ring, and the other end of the limit frame supports the inner wall surface of the sleeve of the through-wall pipe. The utility model adopts a positioning ring sleeved on the through-wall pipe for positioning, which is convenient for installation and disassembly. The limit frame on the positioning ring is used to limit and support the sleeve. In the process of installing the sleeve, the sleeve is sleeved on the through-wall pipe, and the limit frame is against the inner wall of the sleeve for support and limitation. The same length of the limit frame is used to ensure that the distance between the inner wall of the sleeve and the outer wall of the through-wall pipe is equal everywhere and concentrically arranged. The size specifications are unified to solve the problem that the sleeve is not accurately positioned during installation and the center of the sleeve and the pipe cannot be guaranteed to coincide. However, the positioning device in the prior art cannot be adapted to the flange sizes of sleeves or flexible sleeves of different pipe diameters, and the sizes of pipes of different pipe diameters.
