Description

Technical Field

[0001] The utility model relates to the technical field of pipeline well casing positioning, in particular to a pipeline well casing integral pre-embedded positioning tool. Background Art

[0002] A pipe well is a vertical shaft in a building used to arrange vertical equipment pipelines. The more complex and advanced the building is, the more support systems it requires. In addition to basic water supply, power supply, and drainage pipelines, it also has telephone, cable TV, monitoring, ventilation, and other functions. The pipe well casing is convenient for the later installation of the pipe casing. The existing pipe well casing is generally fixed directly on the floor formwork, which is prone to pipe deflection after pouring, making it inconvenient for the later installation of the pipe.

[0003] An existing patent (publication number: CN217840715U) discloses a pipeline well casing integral pre-embedded positioning tool, which can be connected to a limiting mechanism by cooperating with a first bolt through a connecting plate, and the limiting mechanism can be moved and adjusted between symmetrically arranged positioning strips as needed. The limiting strips can limit the position of the casing body by cooperating with a second bolt and a third bolt. Multiple limiting mechanisms can be installed between the symmetrically arranged positioning strips as needed to fix different casing bodies, so that different casing bodies can limit their positions to each other, thereby minimizing the deviation of the casing body during pouring.

[0004] However, the above technical solution still has certain defects. According to actual needs, the installer may need to install and fix multiple casings each time so that different casing bodies can restrict each other's positions, and the limit plate and the annular plate are fixed by multiple groups of bolts. During the installation process, the installer needs to tighten the multiple groups of bolts in turn, which makes the overall installation or subsequent disassembly efficiency low. For this reason, a pipeline well casing integral pre-embedded positioning tool is proposed. Utility Model Content

[0009] As an optimal technical solution for a pipeline well casing integral pre-embedded positioning tool of the utility model, the movable fixed component includes a first sliding block fixedly installed on both sides of the limiting plate, and two groups of the first sliding blocks are provided with a positioning plate on one side, and each group of the positioning plates is provided with a first sliding groove matching the first sliding block on the inner side, and the first sliding block is slidably connected to the first sliding groove.

[0010] As an optimal technical solution for the integral pre-embedded positioning tool for the casing of a pipeline well of the utility model, a second sliding groove is opened on one side of the upper surface of the two groups of positioning plates, a second sliding block is slidably connected in each group of the second sliding groove, and the tops of the two groups of the second sliding blocks are fixedly connected to the same group of movable plates.

[0013] As a preferred technical solution for a pipeline well casing integral pre-embedded positioning tool of the utility model, the bottom outer wall of the casing body is fixedly connected to a limiting bottom plate.

[0014] In summary, the utility model mainly has the following beneficial effects:

[0015] The utility model pulls the four sets of pull handles to drive the pull rod to disengage from the limit hole. At this time, the spring is further squeezed by the fixing ring, and then the limit plug is inserted into the limit hole. The pull handle is released, and the elastic force of the spring itself is used to push the fixing ring and the pull rod to be inserted into the limit hole on one side of the limit plug to complete the fixation. The limit plate can be moved and adjusted between the symmetrically arranged positioning plates as needed, so that the positions of different sleeve bodies can be restricted to each other, thereby minimizing the situation where the sleeve body is skewed during pouring. This fixed connection method is very simple, thereby improving the work efficiency of the installer. BRIEF DESCRIPTION OF THE DRAWINGS
