Description

Technical Field

[0001] The utility model relates to the technical field of pipe well construction, in particular to a positioning device for pipe well casing installation. Background Art

[0002] A tube well is a well that is mechanically dug and equipped with steel pipes or cast iron pipes to reach deep groundwater. Casing is a steel pipe used in oil and gas wells, mainly used to protect the well wall and control the pressure in the well. When installing the tube well casing, it is necessary to measure and locate, and then determine the center position of the casing in order to arrange the pipeline. In this process, a positioning device for the installation of the tube well casing is required.

[0003] The current positioning device is made of concrete poured after the positioning is completed. This method is very labor-intensive and time-consuming. If the positioning is inaccurate or deviations occur, it will increase the workload and be time-consuming and labor-intensive. Utility Model Content

[0015] As a further description of the above technical solution: the length of the linear module is less than the length of the first set of plates.

[0016] By adopting the above technical solution, the linear module drives the slider to move through the operation of the motor, while also limiting the movement range of the slider, so that the slider can only slide within the range of the first set of plates.

[0017] As a further description of the above technical solution: there are four columns, and there are two first sets of plates and two second sets of plates.
