Description

Technical Field

[0001] The utility model belongs to the technical field of subgrade and pavement detection, and particularly relates to a positioning device for subgrade and pavement detection points. Background Technique

[0002] During the subgrade and pavement detection process, the first step is usually to locate the detection points. The traditional positioning method is to measure on the road surface with a tape measure and mark the located detection points with chalk or paint.

[0003] When the existing road surface detection and positioning is carried out, it is usually the staff who use the spraying method for positioning. Due to the presence of many vehicles driving on the road surface, the painted positioning marks will fall off or the color will become dull and difficult to detect after being run over by vehicles for a long time. During subsequent road surface maintenance, it is easy to miss the situation, which affects the safety of the road. Therefore, we propose a positioning device for subgrade and pavement detection points. Content of the Utility Model

[0004] The purpose of the utility model is to provide a positioning device for subgrade and pavement detection points. By setting a grooving component, specifically starting the motor to drive the gear to rotate, the gear drives the turntable to rotate through the gear ring and the connecting shaft, starting the hydraulic cylinder to drive the lifting seat to move downward. When the rotating positioning grooving needle contacts the road surface, it will groove the road surface. After grooving is completed, spraying is carried out at the grooving position through the nozzle, so that the paint surface is not easy to fall off. At the same time, the driving of vehicles on the road surface will not affect the paint surface, and the positioning point can be kept in a state that is easy to observe for a long time, solving the problem that when the existing road surface detection and positioning is carried out, it is usually the staff who use the spraying method for positioning. Due to the presence of many vehicles driving on the road surface, the painted positioning marks will fall off or the color will become dull and difficult to detect after being run over by vehicles for a long time.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a positioning device for subgrade and pavement detection points, including a vehicle body. A paint storage tank is fixedly connected to the top of the vehicle body. A booster pump is fixedly connected to the top of the paint storage tank. A grooving component is arranged at the bottom of the vehicle body. A support frame is fixedly connected to the left side of the top of the vehicle body. A hydraulic cylinder is fixedly connected to the top of the support frame. The grooving component includes a lifting seat;

[0007] A turntable is arranged below the lifting seat. A fixed column is fixedly connected to the center of the top of the lifting seat. The bottom of the turntable contacts several mounting plates. The several mounting plates are arranged in a circumferential array. The parts connected to the tops of the several mounting plates are the same. Several positioning grooving needles are fixedly connected to the bottoms of the several mounting plates. By setting a grooving assembly, specifically, starting the motor to drive the gear to rotate, the gear drives the turntable to rotate through the gear ring and the connecting shaft. Starting the hydraulic cylinder to drive the lifting seat to move downward. When the rotating positioning grooving needles contact the road surface, the road surface will be grooved. After grooving is completed, spraying is carried out at the grooved position through a nozzle, so that the paint surface is not easy to fall off. At the same time, the driving of vehicles on the road surface will not affect the paint surface, and the positioning part can be in a state convenient for observation for a long time.

[0008] Further, a shunt pipe is fixedly connected to the bottom of the vehicle body. Several nozzles are fixedly connected to the bottom of the shunt pipe. The top of the shunt pipe is connected to a booster pump through a hose. The bottom output end of the hydraulic cylinder is fixedly connected to the top of the fixed column. After grooving is completed, move the vehicle body forward. Start the booster pump to transport the paint in the paint storage tank to the shunt pipe through the hose and then spray it out through the nozzles. Then the sprayed paint will be in the grooved positioning slots.

[0009] Further, a motor is arranged on the left side of the fixed column. The bottom of the motor is fixedly connected to the top of the lifting seat. The bottom output end of the motor is fixedly connected to a gear. The gear is meshed and connected to a gear ring on the right side. Starting the motor to drive the gear to rotate, the gear drives the gear ring to rotate. The rotating shaft at the top of the gear ring rotates in the lifting seat and the fixed column. The bottom of the gear ring drives the turntable to rotate through the connecting shaft. Then the mounting plates and the positioning grooving needles rotate together.

[0010] Further, a plug is fixedly connected to the top of the mounting plate. A threaded block is arranged on the right side of the plug. The bottom of the threaded block is fixedly connected to the bottom of the mounting plate. The outer surface of the threaded block is threadedly connected to a nut. The tops of the plug and the threaded block both penetrate through the turntable and extend to the outside. By setting the mounting plate, specifically, when the positioning grooving needle needs to be replaced, use a tool to rotate the nut counterclockwise to disassemble it. Then the fixing of the mounting plate is released. Subsequently, pull the mounting plate downward forcefully. Since the bottom of the block is provided with an inclined surface, the block will be squeezed into the plug, and the plug can be separated from the turntable to complete the disassembly. The operation is simple and convenient, and the positioning grooving needle can be disassembled quickly, which is convenient for subsequent maintenance work.

[0011] Furthermore, limiting grooves are formed on both the left and right sides of the insertion block. Clamping blocks are slidably connected to the inner walls of the two limiting grooves.

Four fixing blocks are fixedly connected to the inner wall of the vehicle body. The tops of the vertical rods penetrate through the fixing blocks and extend to the outside. The vertical rods are slidably connected to the fixing blocks. When the lifting seat moves, the vertical rods slide on the fixing blocks, which can improve stability.

[0013] Furthermore, a rotating shaft is fixedly connected to the top of the gear ring. The top of the rotating shaft penetrates through the lifting seat and extends into the fixed column. The rotating shaft is rotatably connected to both the lifting seat and the fixed column. A connecting shaft is fixedly connected to the bottom of the gear ring. The bottom of the connecting shaft is fixedly connected to the top of the turntable.

[0014] The utility model has the following beneficial effects:

[0015] 1. By setting the grooving assembly in the utility model, specifically, when the motor is started to drive the gear to rotate, the gear drives the turntable to rotate through the gear ring and the connecting shaft. When the hydraulic cylinder is started to drive the lifting seat to move downward, when the rotating positioning grooving needle contacts the road surface, the road surface will be grooved. After grooving is completed, spraying is carried out at the grooving position through the nozzle, so that the paint surface is not easy to fall off. At the same time, the driving of vehicles on the road surface will not affect the paint surface, and the positioning part can be kept in a state convenient for observation for a long time.

[0035] A specific application of this embodiment is:

[0036] During use, move the vehicle body 1 to the position where positioning is required. Then start the motor 124 to drive the gear 125 to rotate. The gear 125 then drives the gear ring 126 to rotate. The rotating shaft 261 at the top of the gear ring 126 rotates within the lifting seat 121 and the fixed column 123. The bottom of the gear ring 126 drives the turntable 122 to rotate through the connecting shaft 262. Then the mounting plate 221 and the positioning grooving needle 222 rotate together. Subsequently, start the hydraulic cylinder 131 to drive the lifting seat 121 to move downward. Then the vertical rod 212 slides on the fixed block 14, which can improve stability. When the rotating positioning grooving needle 222 contacts the road surface, it will groove the road surface. By driving the lifting seat 121 to move downward through the hydraulic cylinder 131, the depth of grooving can be controlled. After grooving is completed, the hydraulic cylinder 131 drives the lifting seat 121 to reset upward, and the motor 124 stops. Then move the vehicle body 1 forward. Start the booster pump 111 to convey the paint in the paint storage tank 11 to the shunt pipe 112 through the hose and spray it out through the nozzle 113. Then the sprayed paint will be in the grooved positioning groove, so that the paint surface is not likely to fall off. At the same time, the driving of vehicles on the road surface will not affect the paint surface, and the positioning point can be in a state convenient for observation for a long time. As the positioning grooving needle 222 is used for a long time, it will be severely worn. Use tools to rotate the nut 225 counterclockwise to disassemble it. Then the mounting plate 221 is released from fixation. Then pull the mounting plate 221 downward forcefully. Since the bottom of the block 226 is provided with an inclined surface, the block 226 will be squeezed into the insert block 223, and the insert block 223 can be separated from the turntable 122 to complete the disassembly. Then install the new mounting plate 221 and the positioning grooving needle 222 on the turntable 122. Insert the top of the mounting plate 221 into the turntable 122 through the insert block 223. Since the top of the block 226 is provided with an inclined surface, the block 226 can be squeezed into the insert block 223. The block 226 squeezes the spring 228. When the block 226 moves above the turntable 122, it will pop out under the action of elasticity to support the mounting plate 221 without the need for staff to support it. Then thread the nut 225 onto the threaded block 224 to fix the mounting plate 221 and complete the replacement.
