Mobile automatic measuring device for highway construction width

Abstract

The invention relates to the technical field of highway construction width measurement, and in particular to a mobile automatic highway construction width measurement device. In order to solve the problem that the measuring ruler is not fixed during the existing highway measurement, the measurement accuracy is reduced. The invention pulls a T rod to make three groups of pistons B rise at the same time, so that a silicone pad is adsorbed on the upper surface of a curb, and a latch can increase the friction between the latch and one side of the curb when a bottom plate moves subsequently, thereby further improving the stability of a fixed head on the curb surface. Afterwards, a cleaning component that reciprocates by extrusion and air blowing can clean impurities on the ground when the bottom plate moves, thereby preventing a tape measure from being bent by pressing on the impurities, thereby affecting the measurement accuracy. Finally, the descending pressure plate can not only tighten the tape measure itself, but also read the value measured by the tape measure through an industrial camera B, thereby achieving the effect of improving the measurement accuracy of the tape measure.

Description

Technical Field

[0001] The invention relates to the technical field of highway construction width measurement, in particular to a mobile automatic highway construction width measurement device. Background Art

[0002] Width measurement is crucial in highway construction. Construction workers will use professional measuring tools, such as total stations and steel rulers. Accurately measure from the designed shoulder edge of the highway to the shoulder edge on the other side. Multiple points of measurement should be taken on both straight and curved sections to obtain the average value to ensure that the width meets the design standards and guarantees highway quality and driving safety. At the same time, the measurement data of different sections should be recorded to facilitate subsequent construction adjustments and inspections. Moreover, during the construction process, multiple re-measurements are required to prevent width deviations due to construction operations. If there are deviations, they should be corrected in time to avoid affecting the progress and performance of the entire highway project.

[0003] In a Chinese patent with application number CN202323035877.8, a highway measuring device for highway construction is disclosed. The device has a good fixing ability at the measuring starting point during measurement, so it is not easy to cause the measuring starting point to deviate or fall during the measurement process, thereby ensuring the measurement process, and it is easy to retract the measuring ruler after the measurement, so the finishing work after the measurement is relatively simple.

[0004] During operation, the above patent only fixes the whole device, while the measuring ruler is still in a loose state. Since the measuring ruler itself is relatively soft, it will bend or fold when it encounters wind, which reduces the measurement accuracy.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1, in order to solve the technical problem of how to improve the measurement accuracy, such as Figure 1-Figure 7 As shown, the following preferred technical solutions are provided: The mobile automatic measuring device for highway construction width includes a base plate 1, a rectangular groove 15 is provided on one side of the base plate 1, a discharge groove 16 is provided on the upper surface of the base plate 1, a detection component 2 for measuring the highway width is fixedly installed on the inner wall of the discharge groove 16, the detection component 2 includes a shell 21 fixedly installed on the inner wall of the discharge groove 16, a tape measure 263 is arranged inside the shell 21, and a fixing component 5 for fixing the tape measure 263 is arranged inside the rectangular groove 15.

By flipping the fixing head 51, the silicone pad 55 is made to fit with the upper surface of the curb. At this time, the fixing plate 57 will be in a vertical state and located on one side of the curb. Then, the adsorption component 56 is pulled to allow the adsorption component 56 to adsorb on the surface of the curb, so that the fixing head 51 is fixed on the surface of the curb. Finally, due to the flipping of the fixing head 51, the latch teeth 571 will be located on one side of the curb. As the tape measure 263 is subsequently pulled, the plurality of groups of latch teeth 571 will increase the friction between the fixing plate 57 and the curb, thereby further improving the stability of the fixing head 51.

[0023] The adsorption component 56 includes a movable column 561 movably arranged inside the circular hole 54. The movable column 561 is provided with three groups, one end of which is movably provided with a T rod 562. A movable plate 563 is fixedly installed between every two groups of the movable columns 561. The other ends of the three groups of movable columns 561 are all fixedly installed with pistons B564. The piston B564 is adapted to the circular hole 54. By pulling the T rod 562, the three groups of movable columns 561 are made to rise at the same time to extract the gas inside the circular hole 54. When the movable column 561 needs to be fixed, the T rod 562 is rotated to make the outer surface of the T rod 562 fit with the outer surfaces of the clamping plate 52 and the vertical plate 53. At this time, the movable column 561 is fixed.

[0024] Storage grooves are provided on both sides of the measuring tape 263, and a step plate 2632 is slidably arranged inside the storing grooves. A slope is provided at one end of the step plate 2632, and a tension spring B is fixedly installed at the other end of the step plate 2632, and the other end of the tension spring B is fixedly connected to the inner wall of the storing groove. A spacing groove 59 is also provided on the inner wall of the fixing head 51, and the spacing groove 59 is adapted to the step plate 2632.

[0025] Vertical plates 22 are fixedly installed on both sides of the shell 21, a shell 23 is fixedly installed on one side of the vertical plate 22, a hole groove 221 is opened on one side of the vertical plate 22, and docking grooves 222 are opened on the lower surfaces of the shell 23 and the vertical plate 22. A reel 26 is arranged inside the shell 21, a round rod 24 is fixedly installed on one side of the reel 26, and the round rod 24 is rotatably connected to the hole groove 221. A gear 25 is fixedly installed on one end of the round rod 24. Two groups of gears 25 are arranged, and both groups of gears 25 are located inside the shell 23. A cross bar A251 is fixedly installed on one side of one group of gears 25. A pressure plate 27 is arranged below the shell 21, a tape measure 263 is arranged inside the reel 26, and a short rod 261 is fixedly installed on the other side of the vertical plate 22 A coil spring 262 is arranged between the short rod 261 and the round rod 24, one end of the coil spring 262 is fixedly mounted on the outer surface of the round rod 24, and the other end of the coil spring 262 is fixedly mounted on the outer surface of the short rod 261. After being fixed by the fixing head 51, the base plate 1 can be pushed forward, and the reel 26 will rotate at this time. While the reel 26 rotates, it will squeeze the coil spring 262 and drive the pressure plate 27 to rise and fall. The compression of the coil spring 262 will increase the subsequent winding speed of the measuring tape 263, and the compressed coil spring 262 will also straighten the measuring tape 263 while the base plate 1 moves. The straightened measuring tape 263 can not only facilitate subsequent readings but also avoid measurement errors caused by bending of the measuring tape 263.

[0026] A roller A271 is provided on the lower surface of the pressure plate 27, and side grooves 272 are provided on both sides of the pressure plate 27. An L plate 273 is slidably provided inside the side groove 272. The L plate 273 is adapted to the docking groove 222. A compression spring 274 is fixedly installed on one end of the L plate 273, and the other end of the compression spring 274 is fixedly connected to the inner wall of the side groove 272. A plurality of groups of teeth A276 are fixedly installed on one side of the L plate 273, and the teeth A276 are meshed with the gear 25. Magnetic blocks 275 are fixedly installed on both sides of the L plate 273. A limit plate 279, an industrial camera A277 and an industrial camera B are fixedly installed on the lower surface of the pressure plate 27. 278, there are two groups of limit plates 279, one side of the industrial camera B278 is on the same horizontal line as one side of the pressure plate 27, and the tape measure 263 is located between the two groups of limit plates 279. The pressure plate 27 can be lowered by the roller A271, and the lowering of the pressure plate 27 can change the tape measure 263 from an inclined state to a horizontal state, and then it does not hinder the movement of the base plate 1. Then, the limit plates 279 can prevent the tape measure 263 from moving around, and then the industrial camera A277 can be used to observe whether the tape measure 263 reaches another curb, and finally the industrial camera B278 can read the value of the tape measure 263.

[0027] A universal wheel 13 is fixedly installed on the lower surface of the base plate 1, an armrest 11 is fixedly installed on the upper surface of the base plate 1, a power box 12 is fixedly installed on one side of the armrest 11, a cleaning component 3 for removing ground impurities is fixedly installed on the upper surface of the base plate 1, a display screen 4 is fixedly installed on the upper surface of the cleaning component 3, the display screen 4 is connected to the signals of industrial camera A277 and industrial camera B278, a pipe opening 14 is opened on the upper surface of the base plate 1, an air storage box 141 is fixedly installed inside the base plate 1, the air port of the air storage box 141 is connected to the pipe opening 14, the measurement value can be clearly read through the display screen 4, and then the base plate 1 can be moved for measurement through the universal wheel 13.

[0028] An inner groove 151 and a plate groove 152 are provided on the inner wall of the rectangular groove 15. The plate groove 152 is located above the inner groove 151. The T-bar 562 is located inside the inner groove 151. The clamping plate 52 and the plate groove 152 are slidably arranged. A rod hole 153 is provided on the upper surface of the bottom plate 1. A latch 154 is provided on the inner wall of the rod hole 153. The latch 154 is matched with the rod hole 153 and the fixing hole 521. When the fixing head 51 is stored, the latch 154 can be inserted into the fixing hole 521 through the rod hole 153 through the rod hole 153, so that the fixing head 51 is fixed inside the rectangular groove 15, so as to prepare for subsequent detection.

[0029] Fine grooves 161 are provided on both sides of the discharge trough 16, and the fine grooves 161 are connected with the docking grooves 222. The fine grooves 161 are adapted to the L-plate 273. An electromagnet 162 is fixedly installed on the inner wall of the fine grooves 161, and a button 121 is fixedly installed on one side of the power box 12. The electromagnet 162 is electrically connected to the power box 12. When the pressure plate 27 is lowered to the road surface with the tape measure 263, the electromagnet 162 can activate its own magnetism, so that the magnetic block 275 is attracted to the electromagnet 162, and the tooth A276 is separated from the gear 25, so as to prevent the pressure plate 27 from continuing to press down the tape measure 263.

[0030] Specifically, when it is necessary to detect the width of the road, the latch 154 is pulled out, and then the fixed head 51 is flipped over so that the fixed head 51 is flush with the measuring tape 263. At this time, as the fixed head 51 is flipped over, the ladder plate 2632 located inside the spacing groove 59 will be forced to be squeezed into the storage groove until the ladder plate 2632 enters the next spacing groove 59 again. Finally, when the fixed head 51 is flipped over to a horizontal state and one end of the measuring tape 263 is on the same horizontal line, the ladder plate 2632 will enter the spacing groove 59 again, so that one end of the measuring tape 263 is fixed to the fixed head 51. After the fixed head 51 is flipped over, the lower surface of the silicone pad 55 will fit the upper surface of the curb, and then the T-bar 562 is pulled to allow one set of movable columns 561 to pass through the movable plate 5 63 rises with the other two groups of movable columns 561, allowing the silicone pad 55 to be adsorbed on the upper surface of the curb and fixing the fixed head 51 on the upper surface of the curb. When the fixed head 51 is turned over to a horizontal state, the latch tooth 571 will fit with one side of the curb to prepare for the subsequent improvement of the stability of the tape measure 263. When the fixed head 51 is fixed, it starts to push the base plate 1. When the base plate 1 just starts to move, the tape measure 263 will be instantly tightened, and the limit plate 279 on the lower surface of the pressure plate 27 will limit the tape measure 263 to move only in the center of the base plate 1. As the base plate 1 moves, the tension on the fixed head 51 will increase, and the latch tooth 571 that fits with one side of the curb will further increase the friction between the latch tooth 571 and the one side of the curb, thereby In order to further improve the stability of the fixed head 51, when the base plate 1 moves, the round rod 24 will rotate with the reel 26 to release the tape measure 263, and the coil spring 262 will be compressed, thereby further tightening the tape measure 263. As the round rod 24 rotates, the teeth A276 meshing with the gear 25 will cause the pressure plate 27 to drop due to the rotation of the gear 25, so that the tape measure 263 as a whole gradually changes from an inclined state to a horizontal state, and the roller A271 on the lower surface of the pressure plate 27 can not only make the tape measure 263 located on the ground, but also reduce the friction between the pressure plate 27 and the tape measure 263. When the roller A271 presses the tape measure 263 to the road surface, the button 121 is pressed to energize the electromagnet 162 to generate magnetism, which attracts the magnetic block 275 so that the teeth A276 and the gears A276 are aligned with each other. When the wheel 25 is misaligned, the pressure plate 27 will not drop any further. When the curb is about to be reached at the other end of the road, the button 121 can be pressed again to cut off the power to the electromagnet 162 and make it lose its magnetism. At this time, the compression spring 274 will bring the L-plate 273 back to its original position, allowing the tooth A276 to mesh with the gear 25 again. At this time, the bottom plate 1 is still moving, and the pressure plate 27 will continue to drop to make the roller A271 concave. Since the roller A271 is made of silicone, as the pressure plate 27 drops, the roller A271 will concave. At this time, the bottom plate 1 will move to the side of the curb with the pressure plate 27. Since the tooth A276 meshes with the gear 25 when the bottom plate 1 moves a certain distance, the tape measure 263 will fit on the side of the curb in a horizontal L shape.At this time, the industrial camera B278 will penetrate the data of the bend of the tape measure 263, and then feedback to the surface of the display screen 4. At this point, the friction force is increased by the adsorption teeth 571 of the adsorption component 56, and the tape measure 263 is tightened, so as to achieve the effect of improving the measurement accuracy of the tape measure 263.

By pressing the movable plate 354, the piston A352 can squeeze the gas inside the L tube 35 into the air storage box 141, and the gas inside the air storage box 141 will be ejected from the air outlet pipe 142 to blow away the impurities on the ground, thereby preventing the tape measure 263 from bending when it is placed on the ground, thereby causing measurement errors.

[0032] A limit block 361 is fixedly installed on one side of the rectangular plate 36, and a long plate 362 is fixedly installed on the other side of the rectangular plate 36. A roller B363 is arranged at one end of the long plate 362, and the outer surface of the roller B363 is in contact with one side of the movable plate 354. A side plate 364 is fixedly installed on one side of the rectangular plate 36, and a cross bar B365 is fixedly installed on one side of the side plate 364. The outer surfaces of the cross bar A251 and the cross bar B365 are both movably sleeved with a connecting plate 366, and the connecting plate 366 is adapted to the wide groove 33. The limit block 361 is slidably connected to the limit groove 34. The rotation of the gear 25 can drive one end of the connecting plate 366 to make a circular motion, while the other end makes a reciprocating motion. As one end of the connecting plate 366 makes a reciprocating motion, the rectangular plate 36 will move back and forth with the roller B363, thereby reciprocatingly squeezing the movable plate 354, so that the impurities on the ground can be cleaned reciprocatingly.

[0033] Specifically, when the bottom plate 1 starts to move, one end of the connecting plate 366 on one side of one set of gears 25 will make a circular motion with the gear 25, and the other end of the connecting plate 366 will make a reciprocating horizontal motion inside the wide groove 33. As the other end of the connecting plate 366 reciprocates horizontally, the rectangular plate 36 will also make a reciprocating horizontal motion, and the long plate 362 located on one side of the rectangular plate 36 will reciprocately squeeze the movable plate 354 with the roller B363, and the movable plate 354 will reciprocately squeeze the gas inside the L tube 35 with the connecting tube 353 and the piston A352, so that the gas inside the L tube 35 is sprayed into the air storage box 141, and the air storage box 14 1 The gas inside will be sprayed from the outlet pipe 142 to the ground to clean the impurities on the ground. Since both ends of the movable plate 354 are in an inclined state, when the roller B363 comes to one end of the movable plate 354, the squeezed spring rod 355 will bring the movable plate 354 back to its original position, allowing the piston A352 to draw air from the inside of the air inlet pipe 351, thereby inflating the inside of the L tube 35 to prepare for the next squeezing. At this point, the impurities on the ground are cleaned by the reciprocating squeezing of the piston A352, preventing the tape measure 263 from bending due to pressing on the impurities and causing measurement errors, and finally achieving the effect of further improving the measurement accuracy of the tape measure 263.
