Positioning method and positioning device for lining trolley template

Abstract

The invention provides a positioning method and device for a lining trolley template. The method comprises the steps that firstly, a tunnel two-dimensional coordinate system and a trolley two-dimensional coordinate system are built, coordinate origins of the tunnel two-dimensional coordinate system and the trolley two-dimensional coordinate system coincide, then, three standard base points are selected on a pouring face of the lining trolley template, and tunnel theoretical coordinate positions of the three standard base points inside the tunnel two-dimensional coordinate system are determinedas tunnel base point coordinates. In actual operation, after the lining trolley is moved to the preset pouring position inside a tunnel, the actual coordinate positions of the three standard base points inside the tunnel two-dimensional coordinate system can be obtained by measuring the actual distance between the tunnel central point O and the three standard base points, the target pouring position of the lining trolley inside the tunnel is determined by calculating the deviation value between the actual coordinate positions and the target coordinate positions, and therefore the lining trolley template is controlled to move to the actual pouring position. By adopting the positioning method and device, the positioning precision and the positioning efficiency of the lining trolley templateare higher.

Description

Technical field [0001] The invention relates to the field of control, in particular to a positioning method of a lining trolley template and a positioning device of the lining trolley template. Background technique [0002] In the construction of the secondary lining of the tunnel, a layer of concrete needs to be poured on the wall of the tunnel to ensure that the tunnel is firm and reliable. Often when the concrete is poured, the template on the lining trolley is used as the pouring template to complete the secondary lining of the tunnel. Important pouring step. The template of the lining trolley is mostly controlled by hydraulic cylinders. However, in the current construction process, the positioning of the template of the lining trolley is mainly controlled by manual measurement. First, a number of templates are set on the surface of the lining trolley. Measuring point, constantly measuring the distance between the measuring point and the tunnel wall, and often heard the staf...

AI Technical Summary

Problems solved by technology

The formwork of the lining trolley is mostly controlled by hydraulic cylinders, but in the current construction process, the positioning of the formwork controlling the lining trolley is mainly carried out by manual measurement. First, multiple Measuring point, constantly measuring the distance between the measuring point and the tunnel wall, often hear the staff shouting at the construction site, "The side cylinder is raised by 3cm!! 3cm!! That's too much!! Go back 2cm!!" The master cylinder goes up!!! Go up again!!" and so on, often after the positioning is completed, there is a certain gap between the formwork of the lining trolley and the target pouring position, and the hydraulic system often causes damage to parts due to poor communication during positioning, which not only affects The progress of the tunnel construction is slowed down, the construction quality cannot be well guaranteed, and the maintenance cost of the hydraulic equipment is also increased.
