Description

Technical Field

[0001] The present invention relates to the technical field of land layout surveying, and specifically to a layout surveying device for land area measurement. Background Art

[0002] Land layout surveying is a way of surveying and mapping. It is a surveying and mapping method that measures the width and length of land through a wire with scales to obtain land area data. Land layout surveying is an indispensable part of engineering construction. Through engineering surveying, the terrain of the construction site is surveyed to facilitate the construction plan, and an alignment device is required for engineering surveying.

[0003] Currently, when conducting land layout surveying, generally, a wire is released from the measuring device by a winch, and one end of the wire is fixed at the starting point of the measurement. Then, the measuring device is moved to the end point of the measurement, so as to measure the area of the land. However, in the actual measurement process, due to the height difference of the land, the height of the wire at the measurement starting point is not at the same level as the height of the wire at the measurement end point, resulting in the measured length of the wire being higher than the actual length, and inaccurate measurement occurs.

[0004] On the other hand, the alignment device for engineering surveying and mapping disclosed in the Chinese Patent Invention Publication No. CN116331963B is easy to replace, not prone to damage, and can set the number of wire reels according to needs, with simple operation. However, the above technical solution does not have the function of comprehensively and efficiently cleaning the wire. Since the wire needs to contact the land during each measurement, a large amount of dust and stains will adhere to the surface of the wire, which is not conducive to long-term use. At the same time, when there is mud in the measurement area, sewage will adhere to the surface of the wire. If the sewage on the surface of the wire is not dried in time, in the long run, the wire will be corroded by the sewage and break. Therefore, we propose a layout surveying device for land area measurement to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to make up for the deficiencies of the prior art and propose a layout surveying device for land area measurement, which can effectively avoid the problem that the height of the wire at the measurement starting point is not at the same level as the height of the wire at the measurement end point, and at the same time has the function of comprehensively and efficiently cleaning the wire.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A layout and measurement device for land area measurement, including a measurement vehicle body. An electric winding roller is installed on the inner bottom wall of the measurement vehicle body. A winding rope is fixed on the outer surface of the electric winding roller. An adjustment mechanism is arranged outside the measurement vehicle body. One end of the winding rope penetrates through the measurement vehicle body and is slidably connected to the measurement vehicle body. The adjustment mechanism is used to adjust the height of the winding rope at the adjustment mechanism.

[0007] A vibration mechanism is arranged inside the measurement vehicle body. The vibration mechanism is used to vibrate the sewage and dust on the surface of the winding rope. The vibration mechanism includes two moving frames. Seven cleaning mechanisms arranged in a circumferential array are arranged between the two moving frames. The seven cleaning mechanisms can blow air on the winding rope in all directions and at multiple angles.

[0008] Further, a fixing pin is fixed at one end of the winding rope away from the electric winding roller. The fixing pin is used to fix one end of the winding rope to the ground. The adjustment mechanism includes a moving seat. A sleeve ring is fixed on the outer surface of the moving seat. The sleeve ring is sleeved on the outside of the winding rope.

[0009] By adopting the above technical solution, a handle is arranged above the fixing pin, which is convenient for the staff to insert the fixing pin into the measurement starting point.

[0010] Further, two auxiliary pressing wheels I are rotatably connected to the inner wall of the moving seat. Both of the two auxiliary pressing wheels I are in transmission connection with the winding rope. A limiting rod I is fixed on the outer surface of the measurement vehicle body. A threaded rod is rotatably connected to the outer surface of the measurement vehicle body. The threaded rod is in threaded connection with the moving seat. The moving seat is slidably connected to the limiting rod I.

[0011] By adopting the above technical solution, when the device is measuring, insert the fixing pin into the ground, then move the device and unwind the wire. After the device moves to the end point, rotate the threaded rod to drive the moving seat to move up and down. The moving seat will drive the winding rope here to move up and down through the two auxiliary pressing wheels I, so that the adjustment mechanism can adjust the height of the winding rope at the adjustment mechanism. During the adjustment process, the staff needs to use a spirit level to measure the winding rope until the winding rope is adjusted to a horizontal state, thus effectively avoiding the problem that the height of the winding rope at the measurement starting point is not on the same level as the height of the winding rope at the measurement end point, and improving the accuracy of the measurement result.

[0012] Furthermore, a transmission mechanism is provided inside the measuring vehicle body. The transmission mechanism is used to transmit power. The transmission mechanism includes a support frame, which is fixed to the measuring vehicle body. A rotating rod is rotatably connected to the upper surface of the support frame. One end of the rotating rod is drivingly connected to an electric winding roller through a belt and a pulley. A worm is fixed to the outer surface of the rotating rod. The transmission mechanism further includes a rotating tube rotatably connected to the support frame. A worm gear is fixed to the outer surface of the rotating tube. The worm gear meshes with the worm.

[0013] By adopting the above technical solution, when driving the electric winding roller to rotate, the electric winding roller will drive the rotating rod to rotate through the belt and the pulley. The rotation of the rotating rod will drive the rotating tube to rotate through the meshing of the worm and the worm gear, providing power for the rotation of the rotating tube.

[0014] Furthermore, a sliding rod is slidably connected to the inner wall of the rotating tube. Two sliding strips are fixed to the outer surface of the sliding rod. Both sliding strips are slidably connected to the rotating tube. A first bevel gear is fixed to the bottom end of the sliding strip. A limiting ring is fixed to the outer surface of the sliding strip. A fixing frame is rotatably connected to the outer surface of the limiting ring. Both moving frames are fixed to the fixing frame.

[0015] By adopting the above technical solution, when the rotating tube rotates, it will drive the sliding rod to rotate through the two sliding strips. The rotation of the sliding rod will drive the second bevel gear to rotate through the first bevel gear. And when the sliding rod rotates, the fixing frame can drive the sliding rod to move up and down through the limiting ring without interfering with the rotation state of the sliding rod.

[0016] Furthermore, long rods are fixed to the outer surfaces of both moving frames. Pressing bumps are fixed to the outer surfaces of both long rods. Ring-shaped convex plates are fixed to both sides of the electric winding roller. The positions of the two ring-shaped convex plates correspond to the two pressing bumps respectively. Two limiting rods two are fixed to the inner bottom wall of the measuring vehicle body. The two limiting rods two are respectively slidably connected to the two long rods.

[0017] By adopting the above technical solution, when driving the electric winding roller to rotate, the electric winding roller can drive the ring-shaped convex plates on both sides to rotate. The rotation of the ring-shaped convex plates can knock the pressing bumps multiple times to make the long rods drive the moving frames to move up and down.

[0018] Furthermore, telescopic springs are sleeved on the outer surfaces of both limiting rods two. One ends of the two telescopic springs are fixed to the inner bottom wall of the measuring vehicle body. The other ends of the two telescopic springs are respectively fixed to the two long rods. Four auxiliary pressing wheels two are rotatably connected between the two moving frames. All four auxiliary pressing wheels two are drivingly connected to the winding rope. A limiting plate is fixed to the inner bottom wall of the measuring vehicle body. The limiting plate is slidably connected to the winding rope.

[0019] By adopting the above technical solution, the annular protrusion plate rotates to hit the compressed protrusion. After the compressed protrusion is compressed, the long rod is reset by the spring pressure of the telescopic spring, so that the long rod drives the moving frame to move up and down, and the four auxiliary pressure wheels drive the winding rope to vibrate, so that the sewage and dust on the surface of the winding rope fall off. By setting the limit plate, the outlet position of the winding rope is limited to prevent the winding rope from deviating and causing the winding rope to disconnect from the auxiliary pressure wheel 2.

[0020] Furthermore, a fixed ring rail is arranged between the two movable frames, and the two movable frames are fixed to the fixed ring rail. The inner wall of the fixed ring rail is sealingly rotatably connected with a rotating cavity ring. The outer surface of the rotating cavity ring is fixed with bevel gear 2, and the bevel gear 2 is meshed with bevel gear 1. The cleaning mechanism includes a blowing nozzle, which is hinged to the rotating cavity ring. The outer surface of the blowing nozzle is fixedly connected with a soft tube, and the end of the soft tube away from the blowing nozzle is fixedly connected with the rotating cavity ring.

[0021] By adopting the above technical solution, when the bevel gear 2 drives the rotating cavity ring to rotate, it will drive the seven cleaning mechanisms to rotate around the winding rope. The air in the rotating cavity ring will be sprayed out from the blowing nozzle through the soft pipe, blowing away the dust on the surface of the winding rope and drying the dirty water on the surface of the winding rope.

[0022] Furthermore, an articulated rod is hinged on the outer surface of the blowing nozzle, a slider is hinged on the end of the articulated rod away from the blowing nozzle, a fixed plate is fixed on the outer surface of the rotating cavity ring, the slider is slidably connected to the fixed plate, a sliding column is fixed on the outer surface of the slider, a wavy ring rail is fixed on the outer surface of the fixed ring rail, and the sliding column is slidably connected to the inner wall of the wavy ring rail.

[0023] By adopting the above technical solution, when the rotating cavity ring rotates, it drives the sliding column to rotate, and the sliding column slides in the wave ring track, so that the sliding column drives the slider to move back and forth. When the slider moves, it drives the blowing nozzle to swing through the hinged rod, so that the blowing nozzle rotates around the winding rope while the blowing nozzle swings back and forth to spray the winding rope at multiple angles.

[0024] Furthermore, a blowing mechanism is provided on one side of the electric winding roller, and the blowing mechanism includes a bellows, and the bellows is fixed to the inner bottom wall of the measuring vehicle body, the inner wall of the bellows is rotatably connected to an impeller plate, and the impeller plate is transmission-connected to the electric winding roller through a belt and a pulley, the outer surface of the bellows is fixedly connected to an air inlet, and the bottom of the bellows is fixedly connected to a soft air pipe, and the end of the soft air pipe away from the bellows is fixedly connected to a fixed ring rail.

[0025] By adopting the above technical solution, when the electric winding roller rotates, the electric winding roller will drive the impeller plate to rotate through the belt and pulley. Air will enter the air box through the air inlet, and be pressurized and conveyed to the flexible air pipe through the rotating impeller plate. The flexible air pipe will transmit the air to the rotating cavity ring.

[0026] Compared with the prior art, the line laying and measuring device for land area measurement has the following beneficial effects:

[0027] First, through the settings of the vibration mechanism and the cleaning mechanism in the present invention, when the electric winding roller winds the winding rope, the annular convex plate rotates and knocks the pressed convex block multiple times. After being pressed, the pressed convex block is reset by the telescopic spring, so that the four auxiliary pressure wheels II drive the winding rope to vibrate up and down, causing the sewage and dust on the surface of the winding rope to fall off. At the same time, the four cleaning mechanisms will rotate and swing reciprocally to blow air on the winding rope. The seven cleaning mechanisms can blow air on the winding rope in all directions and at multiple angles, blowing off the dust on the surface of the winding rope and drying the sewage on the surface of the winding rope, so that the device can clean the winding rope comprehensively and efficiently.

[0028] Second, through the adjustment mechanism and the fixed pin in the present invention, after inserting the fixed pin into the ground, then move the device and lay the line. After the device reaches the end point, rotate the threaded rod to drive the moving seat to move up and down. The moving seat will drive the winding rope here to move up and down through the two auxiliary pressure wheels I, so that the adjustment mechanism can adjust the height of the winding rope at the adjustment mechanism. During the adjustment process, the staff uses a spirit level to measure the winding rope until the winding rope is adjusted to a horizontal state, thus effectively avoiding the problem that the height of the winding rope at the measurement starting point is not on the same level as the height of the winding rope at the measurement end point, and improving the accuracy of the measurement result.

[0029] Other advantages, objectives and features of the present invention will be described to some extent in the subsequent description, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present invention.

After moving the device to the end point, rotate the threaded rod 605 to drive the moving seat 601 to move up and down. The moving seat 601 will drive the winding rope 4 here to move up and down through the two auxiliary pressing wheels 604, so that the adjusting mechanism 6 can adjust the height of the winding rope 4 at the adjusting mechanism 6. During the adjustment process, the staff needs to use a spirit level to measure the winding rope 4 until the winding rope 4 is adjusted to a horizontal state, thus effectively avoiding the problem that the height of the winding rope at the measuring starting point is not on the same level as the height of the winding rope at the measuring end point, and improving the accuracy of the measurement result.

[0054] Please refer specifically to Figure 3 、 Figure 7 and Figure 8 , a transmission mechanism 3 is arranged inside the measuring vehicle body 1. The transmission mechanism 3 is used for transmitting power. The transmission mechanism 3 includes a support frame 301. The support frame 301 is fixed to the measuring vehicle body 1. A rotating rod 306 is rotatably connected to the upper surface of the support frame 301. One end of the rotating rod 306 is drivingly connected to the electric winding roller 2 through a belt and a pulley. A worm 307 is fixed to the outer surface of the rotating rod 306.

The worm gear 303 is meshed with the worm 307. When driving the electric winding roller 2 to rotate, the electric winding roller 2 will drive the rotating rod 306 to rotate through the belt and the pulley. The rotation of the rotating rod 306 will drive the rotating tube 302 to rotate through the meshing of the worm 307 and the worm gear 303, providing power for the rotation of the rotating tube 302.

[0055] A sliding rod 304 is slidably connected to the inner wall of the rotating tube 302. Two sliding strips 305 are fixed to the outer surface of the sliding rod 304. Both of the two sliding strips 305 are slidably connected to the rotating tube 302. A first bevel gear 310 is fixed to the bottom end of the sliding strip 305. A limiting ring 309 is fixed to the outer surface of the sliding strip 305. A fixing frame 308 is rotatably connected to the outer surface of the limiting ring 309.

The rotation of the sliding rod 304 will drive the second bevel gear 311 to rotate through the first bevel gear 310. And when the sliding rod 304 rotates, the fixing frame 308 can drive the sliding rod 304 to move up and down through the limiting ring 309 without interfering with the rotation state of the sliding rod 304.

[0056] Please refer specifically toFigure 7 and Figure 8 On the outer surfaces of both of the two moving frames 701, long rods 702 are fixed. On the outer surfaces of both of the two long rods 702, pressure-receiving bumps 703 are fixed. On both sides of the electric winding roller 2, annular bump plates 704 are fixed. The positions of the two annular bump plates 704 correspond to the two pressure-receiving bumps 703 respectively. On the inner bottom wall of the measuring vehicle body 1, two limiting rods two 705 are fixed. The two limiting rods two 705 are slidably connected to the two long rods 702 respectively. When driving the electric winding roller 2 to rotate, the electric winding roller 2 can drive the annular bump plates 704 on both sides to rotate. The rotation of the annular bump plates 704 can strike the pressure-receiving bumps 703 multiple times, causing the long rods 702 to drive the moving frames 701 to move up and down.

[0057] On the outer surfaces of both of the two limiting rods two 705, telescopic springs 706 are sleeved. One ends of the two telescopic springs 706 are fixed on the inner bottom wall of the measuring vehicle body 1. The other ends of the two telescopic springs 706 are fixed to the two long rods 702 respectively. Four auxiliary pressing wheels two 707 are rotatably connected between the two moving frames 701. All the four auxiliary pressing wheels two 707 are in transmission connection with the winding rope 4. On the inner bottom wall of the measuring vehicle body 1, a limiting plate 708 is fixed. The limiting plate 708 is slidably connected to the winding rope 4. When the annular bump plate 704 rotates, it will strike the pressure-receiving bump 703. After the pressure-receiving bump 703 is pressed, the long rod 702 will be reset under the spring pressure of the telescopic spring 706, so that the long rod 702 drives the moving frame 701 to move up and down reciprocally, causing the four auxiliary pressing wheels two 707 to drive the winding rope 4 to vibrate, so that the sewage and dust on the surface of the winding rope 4 fall off. Through the setting of the limiting plate 708, the outlet position of the winding rope 4 is limited, preventing the winding rope 4 from shifting and causing the winding rope 4 to be disconnected from the transmission connection with the auxiliary pressing wheel two 707.

[0058] Please refer specifically to Figure 8 、 Figure 9 and Figure 10 Between the two moving frames 701, a fixed ring rail 313 is provided. Both of the two moving frames 701 are fixed to the fixed ring rail 313. The inner wall of the fixed ring rail 313 is rotatably connected to a rotating cavity ring 312 in a sealed manner.

When the bevel gear two 311 drives the rotating cavity ring 312 to rotate, it will drive seven cleaning mechanisms 9 to rotate around the winding rope 4. The air in the rotating cavity ring 312 will be ejected from the blowing nozzle 905 through the flexible pipe 906, blowing away the dust on the surface of the winding rope 4 and drying the sewage on the surface of the winding rope 4.

[0059] Please refer particularly to Figure 11 , a hinge rod 904 is hinged to the outer surface of the hair dryer nozzle 905.

A wave-shaped ring track 314 is fixed to the outer surface of the fixed ring track 313. The sliding column 903 is slidably connected to the inner wall of the wave-shaped ring track 314. When the rotating cavity ring 312 rotates, it drives the sliding column 903 to rotate. The sliding column 903 slides in the wave-shaped ring track 314, causing the sliding column 903 to drive the slider 902 to reciprocate. When the slider 902 moves, it will drive the hair dryer nozzle 905 to swing through the hinge rod 904. Thus, while the hair dryer nozzle 905 rotates around the coiling rope 4, the hair dryer nozzle 905 reciprocally swings to jet air at multiple angles to the coiling rope 4.

[0060] Please refer particularly to Figure 4 、 Figure 5 and Figure 6 , a blower mechanism 8 is provided on one side of the electric winding roller 2. The blower mechanism 8 includes an air box 801.

One end of the flexible air pipe 804 away from the air box 801 is fixedly communicated with the fixed ring track 313. When the electric winding roller 2 rotates, the electric winding roller 2 will drive the impeller plate 803 to rotate through the belt and the pulley. Air enters the air box 801 through the air inlet 802 and is pressurized and conveyed to the flexible air pipe 804 through the rotating impeller plate 803. The flexible air pipe 804 transmits the air to the rotating cavity ring 312.

[0061] Working principle: When conducting land measurement, insert the fixing pin 5 at the measurement starting point. The staff drives the measuring vehicle body 1 to move and controls the electric winding roller 2 to release the coiling rope 4. When reaching the measurement end point, rotate the threaded rod 605 to drive the moving seat 601 to move up and down. The moving seat 601 will drive the coiling rope 4 at this place to move up and down through the two auxiliary pressing wheels 604, so that the adjusting mechanism 6 can adjust the height of the coiling rope 4 at the adjusting mechanism 6. During the adjustment process, the staff needs to use a spirit level to measure the coiling rope 4 until the coiling rope 4 is adjusted to a horizontal state, thereby effectively avoiding the problem that the height of the coiling rope at the measurement starting point is not at the same level as the height of the coiling rope at the measurement end point, and improving the accuracy of the measurement result.

[0062] When winding up the winding rope 4, the driving electric winding roller 2 rotates to wind up the winding rope 4. When the electric winding roller 2 rotates, it will drive the annular bump plates 704 on both sides to rotate. The rotation of the annular bump plates 704 will strike the pressed bumps 703. After the pressed bumps 703 are pressed, the long rod 702 will be reset under the spring pressure of the telescopic spring 706, so that the long rod 702 drives the moving frame 701 to move up and down reciprocally, and the four auxiliary pressing wheels II 707 drive the winding rope 4 to vibrate, so that the sewage and dust on the surface of the winding rope 4 fall off due to the vibration.

[0063] When the electric winding roller 2 rotates, the electric winding roller 2 will drive the impeller plate 803 to rotate through the belt and pulley. The air will enter the air box 801 through the air inlet 802 and be pressurized and conveyed to the flexible air pipe 804 through the rotating impeller plate 803. The flexible air pipe 804 will transmit the air to the rotating cavity ring 312.

[0064] When the electric winding roller 2 rotates, the electric winding roller 2 drives the rotating rod 306 to rotate through the belt and pulley. The rotating rod 306 drives the rotating pipe 302 to rotate through the meshing of the worm 307 and the worm gear 303. The rotation of the rotating pipe 302 drives the sliding rod 304 to rotate through the two sliding strips 305. The rotation of the sliding rod 304 drives the rotating cavity ring 312 to rotate through the meshing of the bevel gear I 310 and the bevel gear II 311. The rotation of the rotating cavity ring 312 will drive the seven cleaning mechanisms 9 to rotate around the winding rope 4. The air in the rotating cavity ring 312 will be ejected from the blowing nozzle 905 through the flexible pipe 906. At the same time, when the rotating cavity ring 312 rotates, it drives the sliding column 903 to rotate. The sliding column 903 slides in the wave ring rail 314, so that the sliding column 903 drives the slider 902 to move reciprocally. When the slider 902 moves, it will drive the blowing nozzle 905 to swing through the hinge rod 904. Therefore, while the blowing nozzle 905 rotates around the winding rope 4, the blowing nozzle 905 swings reciprocally to jet air at multiple angles to the winding rope 4, blowing off the dust on the surface of the winding rope 4 and drying the sewage on the surface of the winding rope 4, so that the device can clean the winding rope 4 comprehensively and efficiently.
