Description

Technical Field

[0001] The invention relates to the technical field of land setting-out measurement, in particular to a setting-out measurement device for land area measurement. Background Art

[0002] Land laying out measurement is a form of surveying and mapping. It is a surveying and mapping method that measures the width and length of the land by a reel with a scale to obtain land area data. Land laying out measurement is an indispensable part of engineering construction. Engineering measurement is used to survey the topography of the project construction to facilitate construction planning. Engineering measurement requires the use of a laying-out device.

[0003] At present, when conducting land line measurement, the wire is generally unwound from the measuring device through a winder, and one end of the wire is fixed at the starting point of the measurement. Then the measuring device is moved to the measuring end point, so that the area of ​​the land can be measured. However, in the actual measurement process, due to the height difference of the land, the height of the wire at the measuring starting point and the height of the wire at the measuring end point are not at the same level, resulting in the measured length of the wire being higher than the actual length, resulting in inaccurate measurement.

[0004] On the other hand, the wire-laying device for engineering surveying and mapping disclosed in the Chinese invention patent application publication number CN116331963B is easy to replace, not prone to damage, and can set the number of wire reels as needed, making it easy to operate. However, the above technical solution does not have the function of comprehensive and efficient cleaning of the wire reel. Since the wire reel needs to contact the ground during each measurement, a large amount of dust and stains will adhere to the surface of the wire reel, 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 reel. If the sewage on the surface of the wire reel is not cleaned in time, the wire reel will be corroded by the sewage and break in the long run. Therefore, we propose a wire-laying measurement 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 shortcomings of the prior art and propose a wire-laying measurement device for land area measurement. The device can effectively avoid the problem that the height of the wire winding at the measuring starting point and the height of the wire winding at the measuring end point are not at the same level, and at the same time has the function of comprehensive and efficient cleaning of the wire winding.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a land area measurement device, comprising a measuring vehicle body, an electric winding roller is installed on the inner bottom wall of the measuring vehicle body, a winding rope is fixed on the outer surface of the electric winding roller, an adjustment mechanism is arranged on the outside of the measuring vehicle body, one end of the winding rope passes through the measuring vehicle body and is slidably connected to the measuring vehicle body, and the adjustment mechanism is used to adjust the height of the winding rope at the adjustment mechanism; A vibration mechanism is arranged inside the measuring vehicle body, and the vibration mechanism is used to vibrate the sewage and dust on the surface of the winding rope. The vibration mechanism includes two mobile frames, and seven cleaning mechanisms in a circular array are arranged between the two mobile frames. The seven cleaning mechanisms can perform all-round and multi-angle blowing operations on the winding rope.

[0007] Furthermore, a fixing pin is fixed to one end of the winding rope away from the electric winding roller, and the fixing pin is used to fix one end of the winding rope to the ground. The adjustment mechanism includes a movable seat, and a ring is fixed to the outer surface of the movable seat, and the ring is sleeved on the outside of the winding rope.

[0008] By adopting the above technical solution, a handle is provided above the fixing pin, which facilitates the staff to insert the fixing pin into the measurement starting point.

[0009] Furthermore, the inner wall of the movable seat is rotatably connected to two auxiliary pressure wheels, and the two auxiliary pressure wheels are both connected to the winding rope transmission. A limiting rod is fixed to the outer surface of the measuring vehicle body, and a threaded rod is rotatably connected to the outer surface of the measuring vehicle body. The threaded rod is threadedly connected to the movable seat, and the movable seat is slidably connected to the limiting rod.

[0010] By adopting the above technical solution, when the device is measuring, the fixing pin is inserted into the ground, and then the device is moved and the line is released. After the device moves to the end point, the threaded rod is rotated to drive the moving seat to move up and down, and the moving seat will drive the winding rope here to move up and down through two auxiliary pressure wheels, so that the adjustment mechanism can adjust the height of the winding rope located 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, thereby effectively avoiding the problem that the height of the winding rope at the measurement starting point and the height of the winding rope at the measurement end point are not at the same level, thereby improving the accuracy of the measurement result.

[0011] Furthermore, a transmission mechanism is provided inside the measuring vehicle body, and the transmission mechanism is used to transmit power. The transmission mechanism includes a support frame, and the support frame is fixed to the measuring vehicle body. A rotating rod is rotatably connected to the upper surface of the support frame, and one end of the rotating rod is transmission-connected to an electric winding roller via a belt and a pulley, and a worm is fixed to the outer surface of the rotating rod. The transmission mechanism also includes a rotating tube rotatably connected to the support frame, and a worm wheel is fixed to the outer surface of the rotating tube, and the worm wheel is meshed with the worm.

[0012] By adopting the above technical solution, when the electric winding roller is driven to rotate, the electric winding roller will drive the rotating rod to rotate through the belt and the pulley, and the rotation of the rotating rod will drive the rotating tube to rotate through the engagement of the worm and the worm wheel, thereby providing power for the rotation of the rotating tube.

[0013] Furthermore, the inner wall of the rotating tube is slidably connected with a sliding rod, and two sliding strips are fixed on the outer surface of the sliding rod. Both of the sliding strips are slidably connected with the rotating tube, and a bevel gear is fixed at the bottom end of the sliding strip. A limiting ring is fixed on the outer surface of the sliding strip, and the outer surface of the limiting ring is rotatably connected with a fixed frame, and both of the movable frames are fixed to the fixed frame.

[0014] By adopting the above technical solution, when the rotating tube rotates, the sliding rod will be driven to rotate through the two sliding bars, and the rotation of the sliding rod will drive the bevel gear two to rotate through the bevel gear one, and when the sliding rod rotates, the fixed frame can drive the sliding rod to move up and down through the limit ring without interfering with the rotation state of the sliding rod.

[0015] Furthermore, long rods are fixed on the outer surfaces of the two movable frames, and pressure-bearing protrusions are fixed on the outer surfaces of the two long rods. Annular protrusion plates are fixed on both sides of the electric winding roller, and the positions of the two annular protrusion plates correspond to the two pressure-bearing protrusions respectively. Two limit rods 2 are fixed to the inner bottom wall of the measuring vehicle body, and the two limit rods 2 are slidably connected to the two long rods respectively.

[0016] By adopting the above technical solution, when the electric winding roller is driven to rotate, the electric winding roller can drive the annular protrusion plates on both sides to rotate. The rotation of the annular protrusion plates can knock the compressed protrusions multiple times to make the long rod drive the movable frame to move up and down.

[0017] Furthermore, the outer surfaces of the two limit rods are sleeved with telescopic springs, one end of the two telescopic springs is fixed to the inner bottom wall of the measuring vehicle body, and the other ends of the two telescopic springs are respectively fixed to two long rods, four auxiliary pressure wheels are rotatably connected between the two mobile frames, the four auxiliary pressure wheels are all connected to the winding rope transmission, and a limit plate is fixed to the inner bottom wall of the measuring vehicle body, and the limit plate is slidably connected to the winding rope.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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 the pulley, the air will enter the bellows through the air inlet, and will be pressurized and transported to the soft air pipe through the rotating impeller plate, and the soft air pipe will transmit the air to the rotating cavity ring.

[0025] Compared with the prior art, the land area measurement device has the following beneficial effects: 1. The present invention arranges a vibration mechanism and a cleaning mechanism. When the electric winding roller winds up the winding rope, the annular protrusion plate rotates and strikes the pressed protrusion multiple times. After the pressed protrusion is compressed, it is reset by the telescopic spring, so that the four auxiliary pressure wheels drive the winding rope to vibrate up and down, so that the dirty water and dust on the surface of the winding rope fall off. At the same time, the four cleaning mechanisms will rotate and swing back and forth to blow air on the winding rope. The seven cleaning mechanisms can perform all-round and multi-angle blowing operations on the winding rope, blow away the dust on the surface of the winding rope and dry the dirty water on the surface of the winding rope, so that the device can comprehensively and efficiently clean the winding rope.

[0026] 2. The present invention uses an adjustment mechanism and a fixing pin. After the fixing pin is inserted into the ground, the device is moved and the line is released. After the device reaches the end point, the threaded rod is rotated 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 two auxiliary pressure wheels, so that the adjustment mechanism can adjust the height of the winding rope located 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, thereby effectively avoiding the problem that the height of the winding rope at the measurement starting point and the height of the winding rope at the measurement end point are not at the same level, thereby improving the accuracy of the measurement result.

[0044] 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, and the air will enter the bellows 801 through the air inlet 802, and will be pressurized and transported to the soft air pipe 804 through the rotating impeller plate 803, and the soft air pipe 804 will transmit the air to the rotating cavity ring 312.
