[0024] The technical solutions of the embodiments of the present application are described in detail below in combination with the drawings.
[0025] In combination with Figs. 1-3 , the present application provides a device for measuring the occurrence of large structural surface of through well or tunnel, which comprises a compass 2, a support leg 1 rotatably connected to the bottom end of the compass 2, the axis of the support leg 1 is collinear with the axis of the compass 2, a bracket 3 connected to one side of the compass 2, a three-way laser pointer assembly 4 rotatably connected to the top end of the bracket 3, an angle gauge 5 provided on the three-way laser pointer assembly 4, a pointer connected to one end of the bracket 3, the pointer is located on one side of the angle gauge 5; a level bubble 6 connected to the compass 2, which facilitates leveling the compass 2. The level bubble 6 is connected to the top surface of the compass 2, and two level bubbles 6 are provided, the included angle between the two level bubbles 6 is 90°, and the two level bubbles 6 arranged vertically can display the overall levelness of the compass 2, which facilitates adjusting the levelness of the compass 2.
[0026] The material of the support 3 is one of aluminum alloy or nylon, and nylon is used in the embodiment, which can effectively avoid affecting the magnetic needle of the compass 2 and improve the measurement accuracy.
[0027] The three-way laser pointer assembly 4 comprises a rotating frame 41, a first laser pointer 42, a second laser pointer 43 and a third laser pointer 44. The top end of the support 3 is connected with a supporting shaft 7. The rotating frame 41 is sleeved and rotationally connected on the supporting shaft 7. The first laser pointer 42, the second laser pointer 43 and the third laser pointer 44 are coplanarly arranged. The coplanar arrangement can ensure that the laser emitted by the three laser pointers is in the same plane, and the measurement effect of the whole structural surface is more accurate. When the compass 2 is leveled and the reading of the protractor 5 is 0, the coplanar plane of the three laser pointers is parallel to the WE direction, and the coplanar plane and the surface of the compass 2 are in a perpendicular state. The first laser pointer 42 and the second laser pointer 43 are coaxially and collinearly connected on the rotating frame 41, and the directions of the first laser pointer 42 and the second laser pointer 43 are opposite. The third laser pointer 44 is connected to the top end of the rotating frame 41 and is directed upward. The third laser pointer 44 is perpendicular to the first laser pointer 42.
[0028] The protractor 5 is connected to the rotating frame 41 through a supporting arm. The side plane of the protractor 5 is perpendicular to the axis of the first laser pointer 42.
[0029] The axis of the first laser pointer 42, the axis of the supporting shaft 7 and the center line of the protractor 5 are collinearly arranged, which can ensure that the protractor 5 accurately measures the rotation angle of the first laser pointer 42 relative to the supporting shaft 7, and ensure that the measured reading is the inclination angle of the structural surface.
[0030] The support 3 is arranged on the side where the pointer E of the compass 2 is directed.
[0031] The bottom end of the compass 2 is connected with a rotating frame through a spherical hinge. The rotating frame is connected with the supporting leg 1 through bolts. The compass can be arbitrarily rotated relative to the supporting leg 1, and the leveling performance is better. The compass 2 and the supporting leg 1 can be disassembled from each other, which is convenient for carrying.
[0032] The use steps of the large structural surface occurrence measuring device for shafts and tunnels are as follows:
[0033] Open the laser pointer, and point the first laser pointer 42 to the structural surface on one side of the roadway.
[0034] Hold and move the measuring device, and point the second laser pointer 43 to the structural surface on the other side of the roadway. Ensure the level of the compass 2 during the movement.
[0035] After the pointing points of the first laser pointer 42 and the second laser pointer 43 are determined, rotate the rotating frame 41 to make the third laser pointer 44 point to the corresponding point on the upper side of the structural surface.
[0036] After the pointing is determined, the pointing of the compass 2 is the strike of the structural plane, the reading of the protractor is the dip of the structural plane, and the strike and dip data are the attitude information of the structural plane.
