fig. 2 is a top view of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
Example 1: as shown in fig. 1-2, a laser direction finder capable of accurately adjusting an angle comprises a laser direction finder 3, wherein the tail end of the laser direction finder 3 is fixed on a support 9, the support 9 is hinged on a fixed seat 5 through two symmetrical pin shafts 11, the fixed seat 5 is hinged below a fixed rod 4 through a pin shaft two 12, the fixed rod 4 is installed on an equipment bracket, a horizontal angle gauge 2 is connected above the fixed rod 4 through a fixed bolt 6 and a connecting plate 10, and a vertical angle gauge 1 is connected on the side wall of the fixed seat 5.
Further, fixing base 5 is an inverted U-shaped plate structure, and support 9 is located the recess inboard of fixing base 5, is equipped with horizontal fine setting screw 7 and perpendicular fine setting screw 8 on the top of fixing base 5 and the lateral wall respectively.
Further, the vertical protractor 1 is located below and adjacent to the horizontal protractor 2. When the fixing base 5 swings left and right along the second pin shaft 12, the vertical protractor 1 is fixedly connected to the side wall of the fixing base 5, different angles can be read out by pointing the vertical protractor 1 to different positions of the horizontal protractor 2, and then the fixing and positioning can be carried out through the horizontal fine adjustment screw 7.
Because the support 9 is hinged in the groove of the fixing seat 5 through the first pin shaft 11, the support 9 can swing up and down in the fixing seat 5 along the first pin shaft 11, the laser direction indicator 3 can point to different scales of the vertical protractor 1, the control and adjustment of vertical precision can be accurately controlled, and then the fixing is carried out through the vertical fine adjustment screw 8.
The vertical protractor can control the laser direction indicator to position the angle in the vertical direction in the tunneling process of the roadway, and the horizontal protractor can control the laser direction indicator to position the angle in the horizontal direction in the tunneling process of the roadway; when the center of the roadway needs to be adjusted in the tunneling process, the laser direction indicator is adjusted according to the corresponding design angle of the scales on the protractor. The angle of the laser direction indicator can be accurately adjusted in the process of underground roadway tunneling; the laser direction indicator adjusting precision is improved, the working procedure is simplified, the labor intensity is reduced, the working efficiency is improved, and a good using effect is obtained.
The parts of the present invention not described in detail are the known techniques of those skilled in the art. Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
