Description

Technical Field

[0001] The present invention relates to the technical field of road measurement equipment, and specifically to a laser slope ratio detector for construction engineering with automatic angle adjustment. Background Art

[0002] During the construction of road projects, the maintenance of slopes is very important. The main function of slopes is to effectively reinforce the road surface, and the designed slope of the slope affects the use effect of the slope. A slope ratio detector is used to measure the slope or slope ratio of a slope, and is commonly found in fields such as civil engineering, road construction, and mining. The slope ratio is usually expressed as the ratio of the vertical height to the horizontal distance. Existing handheld slope ratio detectors can be conveniently adapted to the site for rapid measurement. When in use, the device is placed on the slope surface, and then the turntable where the pointer is located is adjusted to the horizontal state, and then the inclination angle of the slope surface is obtained through the angle formed between the pointer and the angle scale.

For example: when using the existing handheld slope ratio detector, it is necessary to manually adjust the angle of the turntable to the horizontal state, and the operation is relatively cumbersome, which is not conducive to rapid on-site measurement. Moreover, the handheld slope ratio detector has a single function and cannot measure the distance of the on-site construction site as a measurement tool. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

A scale 5 is provided at the bottom of the side end of the measuring instrument main body 1. Auxiliary measurement can be carried out through the scale 5.

[0027] A slope ratio detection device 11 is provided at the middle position inside the measuring instrument main body 1. The rear end of the top of the slope ratio detection device 11 is engaged with a turntable 12, and the front top of the slope ratio detection device 11 is engaged with a servo motor 13. A battery 14 is provided inside the grip 2. A laser ranging device 15 is provided at the front bottom of the slope ratio detection device 11. A level detector 16 and a central control module 17 are provided at the bottom end inside the slope ratio detection device 11. Place the bottom of the measuring instrument main body 1 flat on the road surface, and then turn on the device through the display control panel 4. The inclination angle of the road is obtained through the angle difference detected by the reference level sensor 1164 and the level detector 16, and the calculated data is displayed on the display control panel 4, which is convenient for automatically detecting the slope of the road.

[0028] The slope ratio detection device 11 is provided with a fixed disk 111. Through grooves 112 are provided on both sides inside the fixed disk 111. Clamping tubes 113 are provided inside the through grooves 112. Transmission rods 114 are respectively installed at the end faces of the two through grooves 112. The middle position of the fixed disk 111 is rotationally connected to an adjustment turntable 116, and the side end of the fixed disk 111 is engaged with the transmission rod 114. The end face of the transmission rod 114 is limited by the clamping tube 113, so that the transmission rod 114 is respectively engaged with the turntable 12 and the servo motor 13, and the adjustment turntable 116 can be driven by the turntable 12 to adjust the angle.

[0029] An angle scale 117 is provided on the end face of the fixed disk 111. A card slot 118 is provided at the middle position of the fixed disk 111 and is rotationally connected to the adjustment turntable 116. An anti-slip pad 118 is provided on the end face of the card slot 118, and the anti-slip pad 118 is movably matched with the end face of the adjustment turntable 116. The friction is increased by the contact between the anti-slip pad 118 and the end face of the adjustment turntable 116, so as to avoid the situation of rotation after the adjustment turntable 116 is adjusted.

[0030] A gear teeth 1161 is circumferentially provided on the side end of the adjustment turntable 116. The gear teeth 1161 are meshed and connected with the transmission rod 114.

The pointer 1163 is perpendicular to the end face of the leveling staff 1162. A reference level sensor 1164 is provided at the bottom of the leveling staff 1162. By meshing the gear teeth 1161 with the transmission rod 114, rotating the turntable 12 drives the adjustment turntable 116 to rotate, so that the bubble in the leveling staff 1162 is located at the middle position. Then, the slope is obtained by checking the angle difference between the pointer 1163 and the angle scale 117.

[0031] Based on the above embodiments, the specific working principle is as follows: Place the bottom of the measuring instrument body 1 flat on the road surface, and then turn on the device through the display control panel 4. The angle of the slope can be automatically measured by the level detector 16, and the measured slope is transmitted to the central control module 17 for calculation and processing. The central control module 17 controls the forward or reverse rotation of the servo motor 13 to engage with the adjustment turntable 116 for angle adjustment. After the detection by the reference level sensor 1164 reaches the horizontal level, the servo motor 13 can be controlled to stop. The inclination angle of the road can be obtained through the angle difference detected by the reference level sensor 1164 and the level detector 16, and the calculated data is displayed on the display control panel 4, which is convenient for automatically detecting the slope of the road. Then, by meshing the gear teeth 1161 with the transmission rod 114, rotating the turntable 12 drives the adjustment turntable 116 to rotate, so that the bubble in the leveling staff 1162 is located at the middle position. Then, the slope is obtained by checking the angle difference between the pointer 1163 and the angle scale 117, and the slope of the road can be manually detected. The slope of the road is measured by both manual and automatic methods, which is convenient for the construction personnel to operate.

[0032] Embodiment 2: Please refer to Figures 6 - 7 , the specific embodiments of the present invention are as follows: The laser ranging device 15 is provided with a laser rangefinder 151.

The protective plate 154 can rotate up and down through the rotating shaft 155, and then the protective plate 154 is fixed to the end face of the protective groove 153 through the buckle 156.

[0034] The protective ring 157 is made of rubber, and the inside of the protective ring 157 is in a concave shape. The protective ring 157 can be stuck on the side end face of the laser rangefinder 151 through the internal concave shape, and the side end face of the laser rangefinder 151 is supported by the protective ring 157.

[0035] Based on the above embodiments, the specific working principle is as follows: When the laser rangefinder 151 slides outwards in the sliding seat 152, the laser rangefinder 151 can be made to fit the ground to measure the distance of the road. And the measured data can be processed by the central control module 17 and then displayed through the display control panel 4, which is convenient for the staff to obtain the distance detection data. Then, by sliding the laser rangefinder 151 inwards and flipping the protective plate 154 upwards, the protective ring 157 is stuck on the end face of the laser rangefinder 151 for fixation, avoiding the situation that the laser rangefinder 151 is damaged due to collision. At the same time, the side end face of the laser rangefinder 151 is supported by the protective ring 157, which can fix the laser rangefinder 151 without contacting the laser emitting surface of the laser rangefinder 151, avoiding soiling the laser emitting surface.
