[0002] At present, for the detection of the cross-section width of various structures, it is generally measured directly with a steel tape or measured with a measuring device or measured with a rangefinder. When measuring with a steel tape, when determining whether two points are in a cross-section, it is generally greatly affected by human subjective consciousness and has a large measurement error; when measuring with a measuring device, although the cross-section width can be accurately measured, a measuring device is required and it takes a long time, which runs counter to the current advocated green and intelligent detection. At the same time, the measurement of the cross-section width of a spatial structure with a small clearance height is limited. When using a rangefinder, it is impossible to determine whether the two measured points are in the same cross-section, and there is a large measurement error. Summary of the Invention

[0004] To achieve the above purpose, the present invention provides the following technical solutions:
[0005] A cross-section width detector includes a housing. A dial is provided at the center position on the side of the housing. The outer edge of the dial is marked with cross-slope angle scales. A worm gear is arranged inside the dial. The worm gear is rotationally connected to the dial and is concentric with the dial. A tube level is arranged inside the worm gear. Both ends of the tube level are fixed on the inner side wall of the worm gear. A pointer is fixedly connected to the outer edge of the worm gear; One side of the top of the housing is provided with a turntable, and a laser rangefinder is fixed on the top of the turntable. On the side of the top of the housing away from the turntable, a cross-slope adjustment knob is provided. A worm is arranged at the bottom of the cross-slope adjustment knob. The worm is vertically arranged and meshes with the worm gear.
[0006] Preferably, a controller is arranged at the bottom of the housing, and the controller is in signal connection with the laser rangefinder.
[0007] Preferably, screw adjusters for leveling the device are symmetrically arranged at the two bottom corners of the controller.
[0008] Preferably, the rotation angle range of the laser rangefinder is ±10°, and the included angle parameter between the measured cross-section and the axis is input through the controller.
[0009] Preferably, the extending direction of the pointer is perpendicular to the extending direction of the tube level.
[0010] Preferably, the degrees of the cross-slope angle scales increase symmetrically from the center to both sides.
[0011] Preferably, a micro motor is provided at the top of the housing. The micro motor is located below the turntable, and the motor shaft is connected to the turntable.
[0012] A usage method of a cross-section width detector, which is implemented based on a cross-section width detector, includes the following steps:
[0013] Step 1, cross slope adjustment: According to the cross slope value of the cross-section drawing and the equipment placement position, turn the cross slope adjustment knob to drive the worm to rotate, and the worm drives the worm wheel to rotate until the bubble in the tubular level is centered. At this time, the pointer points to the current slope value;
[0014] Step 2, leveling: After the cross slope is adjusted, press the side of the laser rangefinder against the wall of the structure, and adjust it using the foot screw adjuster according to the centering of the bubble in the tubular level to make the bubble in the tubular level centered, thus completing the leveling work;
[0015] Step 3, width measurement: Set the left and right rotation angles of the laser rangefinder (7) and the included angle between the cross-section and the axis through the controller (10), start the laser rangefinder (7) to rotate automatically and record data. If the included angle between the measured cross-section and the axis is 90°, the minimum width measured in the measured area is the width of the cross-section. If the included angle between the measured cross-section and the axis is A° and A is other values than 90°, taking the minimum width value of the measured area as the origin, the minimum value measured when rotating left and right by B° (if A > 90, then B = A - 90; if A < 90, then B = 90 - A) is the width of this cross-section.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0024] In order to solve the problems of complex operation and poor measurement accuracy in the existing measurement technology, please refer to Figures 1-3 , the following technical solutions are provided in this embodiment:
[0025] A cross-section width detector includes a housing 1. A dial 2 is provided at the center position on the side of the housing 1. The outer edge of the dial 2 is marked with cross slope angle scales, and the degrees of the cross slope angle scales increase symmetrically from the center to both sides.
[0026] A worm gear 3 is arranged inside the dial 2. The worm gear 3 is embedded in the dial 2 and rotatably connected to the dial 2. The worm gear 3 and the dial 2 are concentric structures. A tube level 4 is arranged inside the worm gear 3, and both ends of the tube level 4 are fixed on the inner side wall of the worm gear 3.
[0027] On one side of the top of the housing 1 away from the turntable 6, a cross slope adjustment knob 8 is provided. A worm 9 is arranged at the bottom of the cross slope adjustment knob 8. The worm 9 is vertically arranged and meshes with the worm gear 3; a pointer 5 is fixedly connected to the outer edge of the worm gear 3, and the extending direction of the pointer 5 is perpendicular to the extending direction of the tube level 4.
[0028] Specifically, by rotating the cross slope adjustment knob 8, the worm 9 can be driven to rotate. The worm 9 meshes with the worm gear 3 to make the worm gear 3 rotate, and then drives the tube level 4 to rotate around its center point until the bubble in the tube level 4 is centered, indicating that the detector is in a horizontal state. At this time, the pointer 5 points to the current slope value, thus completing the cross slope adjustment. Through the cooperation of the cross slope adjustment knob 8 and the tube level 4, different cross slope angles and terrain conditions can be adapted.
[0029] On one side of the top of the housing 1, a turntable 6 is provided, and a laser rangefinder 7 is fixed on the top of the turntable 6.
[0030] At the bottom of the housing 1, there is a controller 10. The controller 10 is signal-connected to the laser rangefinder 7. The controller 10 sets the rotation angle of the laser rangefinder 7 and the included angle between the cross-section and the axis. The laser rangefinder 7 automatically rotates within the set range and records data, and calculates and outputs the cross-section width value according to the included angle parameter between the cross-section and the axis.
[0031] At the two symmetric bottom corners of the controller 10, there are screw regulators 11 for leveling the equipment. The screw regulator adopts the fuams-b0-s external thread leveling regulator.
[0032] The rotation angle range of the laser rangefinder 7 is ±10°, and the included angle parameter between the measured cross-section and the axis is input through the controller 10.
[0033] At the top of the housing 1, there is a micro motor. The micro motor is located below the turntable 6, and the motor shaft is connected to the turntable 6.
[0034] A method for using a cross-section width detector, which is implemented based on a cross-section width detector, includes the following steps:
[0035] Step 1, cross-slope adjustment: According to the cross-slope value of the cross-section drawing and the equipment placement position, turn the cross-slope adjustment knob 8 to drive the worm 9 to rotate. The worm 9 drives the worm gear 3 to rotate until the bubble in the tube level 4 is centered. At this time, the pointer 5 points to the current slope value;
[0036] Step 2, leveling: After the cross-slope is adjusted, press the side of the laser rangefinder 7 against the structure wall, and adjust it with the screw regulator 11 according to the centering situation of the bubble in the tube level 4 to make the bubble in the tube level 4 centered, and the leveling work is completed;
[0037] Step 3, width measurement: Set the left and right rotation angles of the laser rangefinder (7) and the included angle between the cross-section and the axis through the controller (10), start the laser rangefinder (7) to rotate automatically and record data. If the included angle between the measured cross-section and the axis is 90°, then the minimum width measured in the measured area is the width of the cross-section. If the included angle between the measured cross-section and the axis is A° and A is other values than 90°, then taking the minimum width value in the measured area as the origin, the minimum value measured when rotating left and right by B° (if A > 90, then B = A - 90; if A < 90, then B = 90 - A) is the width of this cross-section.
[0038] Working principle: According to the cross slope value of the cross-section drawing and the placement position of the equipment, turn the cross slope adjustment knob 8 to drive the worm 9 to rotate. The worm 9 drives the worm gear 3 to rotate until the bubble in the tube level 4 is centered. At this time, the pointer 5 points to the current slope value. After the cross slope is adjusted, press the side of the laser rangefinder 7 tightly against the wall of the structure. Adjust it with the screw adjuster 11 according to the centering of the bubble in the tube level 4 to make the bubble in the tube level 4 centered, thus completing the leveling work. Set the left and right rotation angles of the laser rangefinder 7 and the included angle between the cross-section and the axis through the controller 10, and start the laser rangefinder 7 to rotate automatically and record the data.
