Description

(5+) DEVICE FOR CREATING SUPPORT PLANES AND MARKINGS

; I.

The invention relates to a geodesic instrumentation and, in particular, to devices for creating geodetic reference planes and lines.

A laser geodesic tool, a tool designed to create reference lines on construction sites, is known, comprising a housing with a laser mounted rotatably in a horizontal plane 11 and tilted in a vertical plane through an angle j 30 ,. These devices allow for marking and measurements on the GPU. The disadvantage of it is the impossibility of creating a vertical reference plane.

The closest to the proposed, technical essence and the achieved result is a device for creating reference geodetic planes and marking structures, containing separately installed sources of laser radiation and a scanner of the laser beam in the plane, made in the form of pentaprism, installed in the housing on the hollow axis t2.

The disadvantages of this device are the impossibility of building mutually perpendicular planes with one installation of the device and low labor productivity, since the orientation of the device is performed at points pre-marked on. object, for example on the stocks.

The purpose of the invention is to expand the functionality and increase productivity.

This goal is achieved by the fact that the scanner casing is made with the possibility of tilting by 90 °; a target sign and two beam-splitting optical units, one of which is made in the form of a cube-prize, are installed in front of the scanner inlet. we / 1 are mounted on a bracket, and the other is made in the form of a pentaprism with a wedge 392 and installed in a housing in front of the inlet of the hollow axis. FIG. 1 shows a diagram of the operation of the device; on -fig. 2 and 3 - the device in two positions; see k view B in figure 2. The device contains laser 1, triggers 2 and 3, body 4 of the scanner of tripods 5 and 6. On the laser body 1, the target mark 7 is installed. The body of the scanner is mounted on the base 8 in bearings 9c with the possibility of tilting 90. On the hollow axis 10 the pentaprism is strengthened 11 The axis 10 and the pentaprism 11 are connected with the lead screw 12. On the axis 10, the limb 13i is fastened to read the angle of rotation of the pentaprism 11. In front of the inlet of the hollow axis 10, there is a beam-splitting unit I made in the form of a pentaprism with a wedge. On the base 8, a bracket 15 is fixed, on which another beam-splitting unit 16 is installed, made in the form of a club prism. To install the case in a fixed position, angles 17 and 18 and a screw 19 are fixed on it. To level the base 8, there are lifting screws 20, and the second target mark 21 is fixed on the bracket 15 on the bracket 15 on the device. The device works as follows. Above the base points a and 5, respectively, a tripod 5 with a laser 1 and a tripod 6c are installed with a screwdriver unit. The center of the beam In combined with the point a. The beam r is aligned with the center of the target mark 21. Puig r, the pass mark 21, is divided in block 16 into two beams a and 5 (. (Get it and). Beam c is aligned with point e located on the same line with points q and 5. To control the correct installation of the sweep device, it is set to the position shown in Fig. 3 and the beam is aligned with the target sign 7 If the center of the rays r and "are aligned with the centers of the target marks 7 and 21, the device is oriented with high precision. , checks and creation of reference planes and lines produced by the lead screw 12, turning and the hollow axis 10 of the pentaprism 11. The angle of rotation of the beam is read over the limb 13. The use of a device for creating reference planes and markings reduces the amount of work, increases productivity, and accuracy of measurements and markings The invention Device for creating reference planes and marking contains a laser and a laser beam scanner, made in the form of a pentaprism, mounted in a housing on a hollow axis, characterized in that, in order to expand its functionality and increase productivity, labor a, the case of the scanner unit can be tilted by 90 °, a target sign and two beam-splitting optical units are installed in front of the entrance hole of the scanner unit, one of which is made in the form of a cube-prism and mounted on a bracket, and the other is made in the form of a pentaprism with a wedge installed in the housing in front of the inlet of the hollow axis.
