Embodiment Construction

[0026] figure 1 It is the optical principle of the present invention: through the parallel light beam incident at any angle α of the prism 1, it converges into a point on the position sensitive sensor 3 of the focal plane of the convex lens 2, assuming that the distance between the point and the axis is h, and the focal length of the convex lens is f, then The following formula holds: α = arctan h f , Then α is the desired horizontal swing angle.

[0027] figure 2 Represents an embodiment of the present invention, wherein prism 1: φ60; lens 2: φ50, f=100; position sensitive sensor 3: 2-dimensional 27×27; the units of dimensions of the above-mentioned components are mm; The digital output dual-axis inclination sensor module NS-15 / PL2; the signal generated by the position sensitive sensor PSD is processed by the processing circuit 5, and the processing circuit 5 is a 2D-PSD circuit board pro...

Abstract

The invention is a electron laser target for tunnel developing guiding system, which belongs to orientation measuring device, it can be applied to mine, hydraulic tunnel, subway tunnel, municipal pipes, common canals field, the invention arranges edge glass, flat and convex lens, position sensitive sensor PSD, banking indicator and processing circuit along the axis in the barrel machine box; the light sensitive surface of the position sensitive sensor PSD is at the focus plane of the flat and convex lends and vertical to the flat and convex lends axis, the centre of the light sensitive surface is on the axis; the PSD is connected with the processing circuit electric signal. The invention integrates the ELS and the edge glass into one, thus the volume of the ELS is reduced, the operation is simplified, it uses the infrared of the whole station device directly, it is focused by the convex lends, and is placed at the PSD on the focus plane, then it generates current, which is outputted to the external computer after being processed.

Description

technical field [0001] The invention belongs to a positioning measuring device and can be used in the fields of mines, hydraulic tunnels, subway tunnels, municipal pipelines, common ditches and the like. Background technique [0002] Shield tunneling technology is an engineering construction technology for underground excavation tunnels. It is developed with the development of modern transportation, underground engineering, mining, water conservancy projects, municipal construction and electrical communication facilities. The early shield machine mainly used the shield shell unique to the shield machine as a support to prevent the collapse of the stratum, so as to ensure the safety of various operations such as excavation and lining inside it. The excavation is basically manual. Excavation method. With the increasing number of tunnel projects, in order to adapt to the construction requirements under different conditions and improve construction efficiency, in addition to co...
