DETAILED DESCRIPTION

[0022] like Figure 1-Figure 5As shown, the utility model provides a technical solution: a three-dimensional scanning device for a tunnel face, comprising a mounting seat 1, a concave frame 10 is rotatably connected to the top of the mounting seat 1, a round rod 11 is rotatably connected to the inner side of the concave frame 10, a base 12 is passed through the round rod 11, the base 12 is fixedly connected to the round rod 11, a three-dimensional scanner 13 is fixed to the top of the base 12, and an adjustment component 8 and a driven component 9 are arranged on the surfaces of the mounting seat 1 and the concave frame 10, and the adjustment component 8 comprises: an L-shaped plate 80, a second motor 81, a rotating shaft 82, a gear one 83, a gear two 84, a gear three 85, a connecting piece 86, a support rod one 860, a support rod two 861, a disk 862, a latching tooth 863, a rotating rod 864, and a through hole one 87.

[0023] The L-shaped plate 80 is fixed on the surface of the concave frame 10. A motor 2 81 is fixed on the surface of the L-shaped plate 80. A rotating shaft 82 is fixed on the output shaft surface of the motor 2 81. The rotating shaft 82 penetrates the concave frame 10 and is rotatably connected to the concave frame 10. A gear 1 83 is rotatably connected to the surface of the concave frame 10. A through hole 1 87 is provided on the surface of the gear 1 83. The through hole 1 87 is penetrated by the rotating shaft 82. A gear 2 84 is rotatably connected to the surface of the concave frame 10. The gear 2 84 meshes with the gear 1 83. The surface of the concave frame 10 rotates. The adjusting assembly 8 further comprises a linkage 86, which comprises a support rod 1 860, which is fixed on the surface of the gear 3 85, and a support rod 2 861 is fixed on the surface of the gear 2 84. The concave frame 10 is penetrated by a rotating rod 864, and one end of the rotating rod 864 is fixedly connected to one end of the round rod 11, and a disc 862 is penetrated and fixed on the end of the rotating rod 864 away from the round rod 11, and a latch 863 is fixed on the surface of the disc 862, and a through hole 87 is formed. The inner wall of the through hole 96 is provided with a ratchet, the surface of the rotating shaft 82 is provided with a pawl, the inner wall of the through hole 96 is provided with a ratchet in the opposite direction to the inner wall of the through hole 1 87, the surface corresponding to the rotating shaft 82 and the through hole 96 is provided with a pawl in the opposite direction to the surface corresponding to the through hole 1 87, the support rod 1 860 and the support rod 2 861 are provided with four groups, the motor 2 81 is turned on to rotate forward, the gear 1 83 rotates through the ratchet and the pawl, so that the gear 2 84 and the gear 3 85 rotate, at this time, the support rod 1 860 and the support rod 2 861 rotate, when the support rod When the surface of the second rod 861 conflicts with the surface of the latch tooth 863, the latch tooth 863 and the disk 862 will be driven to rotate. When the surface of the second rod 861 does not conflict with the latch tooth 863, the first rod 860 will conflict with the surface of the latch tooth 863, thereby causing the latch tooth 863 and the disk 862 to reverse. When the disk 862 rotates, it will drive the rotating rod 864 to rotate, thereby causing the base 12 and the three-dimensional scanner 13 to rotate through the round rod 11, and then the tilt angle can be adjusted without manual adjustment, thereby improving work efficiency.

[0024] It should be noted that support rod 1 860 and support rod 2 861 are respectively distributed on one side of gear 3 85 and gear 2 84, and the initial state of support rod 1 860 and support rod 2 861 is the state where the two are farthest apart. Therefore, when the disk 862 rotates, it will only drive one of the support rod 1 860 and support rod 2 861 to rotate. Since gear 3 85 and gear 2 84 are meshed with each other, when the disk 862 rotates in a single direction, it can drive gear 3 85 and gear 2 84 to reciprocate respectively, that is, when the tilt angle of the three-dimensional scanner 13 is too large, it will automatically rotate.

[0025] The driven assembly 9 includes a gear 4 90, which is rotatably connected to the side of the concave frame 10 away from the gear 1 83, and the concave frame 10 is rotatably connected to the side of the gear 1 83 away from the gear 1 83. The gear 5 91 is meshed with the gear 4 90, and the surface of the gear 5 91 is provided with a through hole 2 96, and the shaft 82 passes through the through hole 2 96. A connecting rod 92 is fixed to the surface of the gear 4 90, and a rotating plate 93 is fixed to the end of the connecting rod 92 away from the gear 4 90, and a resisting plate 94 is fixed to the surface of the rotating plate 93, and a mounting seat A stabilizing plate 95 is fixed on the top of 1, and the stabilizing plate 95 contacts the surface of the contact plate 94. The motor 2 81 is turned on and reversed. Since the gear 1 83 and the rotating shaft 82 are matched with a ratchet and a pawl, the gear 1 83 cannot rotate at this time. The gear 5 91 rotates to drive the gear 4 90 to rotate, so that the rotating plate 93 and the contact plate 94 are driven to rotate through the connecting rod 92, so that the surface of the contact plate 94 contacts the surface of the stabilizing plate 95, so that the concave frame 10 rotates, and then the lateral angle of the three-dimensional scanner 13 is adjusted.

[0026] A motor 2 is fixed to the bottom of the mounting base 1, a threaded rod 5 is fixed to the bottom of the output shaft of the motor 2, a slider 6 passes through the threaded rod 5, the slider 6 is threadedly connected to the threaded rod 5, a movable rod 7 is hinged on the surface of the slider 6, a bracket 4 is hinged on the end of the movable rod 7 away from the slider 6, a fixed base 3 is hinged on the top of the bracket 4, and the fixed base 3 is fixed to the bottom of the mounting base 1. Turning on the motor 2 makes the threaded rod 5 rotate, thereby driving the slider 6 to move downward, so that the movable rod 7 moves outward, so that the bracket 4 is opened. At this time, the device can be placed on the ground to keep the three-dimensional scanner 13 stable.

[0027] When it is necessary to perform a three-dimensional scan on the tunnel face, the device is placed in a suitable position, and the motor 12 is turned on to rotate the threaded rod 5, thereby driving the slider 6 to move downward, so that the movable rod 7 moves outward, so that the bracket 4 is opened. When the bracket 4 is opened to a sufficient angle, the motor 12 can be turned off, and the device can be placed on the ground to keep the three-dimensional scanner 13 stable.

[0028] When the angle of the three-dimensional scanner 13 needs to be adjusted, the motor 2 81 is turned on to rotate forward. At this time, the ratchet and the pawl rotate the gear 1 83, thereby driving the gear 2 84 and the gear 3 85 to rotate. At this time, the support rod 1 860 and the support rod 2 861 rotate. When the surface of the support rod 2 861 conflicts with the surface of the latch tooth 863, the latch tooth 863 and the disk 862 will be driven to rotate. When the surface of the support rod 2 861 does not conflict with the latch tooth 863, the support rod 1 860 will conflict with the surface of the latch tooth 863, thereby causing the latch tooth 863 and the disk 862 to reverse. When the disk 862 rotates, it will drive the rotating The rod 864 rotates, thereby causing the base 12 and the three-dimensional scanner 13 to rotate through the round rod 11, and then the angle is adjusted without manual adjustment, thereby improving work efficiency. When the appropriate angle is adjusted, the motor 2 81 can be turned off. When a lateral angle is required, the motor 2 81 is turned on and reversed. At this time, the gear 1 83 cannot rotate, and the gear 5 91 rotates to drive the gear 4 90 to rotate, so that the rotating plate 93 and the contact plate 94 are driven to rotate through the connecting rod 92, so that the surface of the contact plate 94 contacts the surface of the stabilizing plate 95, thereby causing the concave frame 10 to rotate, and then the lateral angle of the three-dimensional scanner 13 is adjusted.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
