Description

Technical Field

[0001] The present invention relates to the technical field of road construction, in particular to municipal road construction equipment with a synchronous detection function. Background Art

[0002] Roads are vital transportation arteries for any region and are sufficient to support the economic development of a region. As of 2022, the total mileage of my country's highway network has reached 5.198 million kilometers, ranking first in the world. The criss-crossing highway network has formed a fully connected China, but nearly one-third of them are old roads. With the increase in traffic, the damage to the roads is also increasing. Roads still need to be continuously expanded and renovated. When building roads, construction workers cannot simply consider leveling the roads, but also need to consider road drainage and lateral pressure of vehicles when cornering at low speeds. Therefore, general roads need to be built with different slopes on straight roads and curves to solve the problems of water accumulation and vehicle lateral pressure.

[0003] Roads usually consist of a base soil layer, a gravel buffer layer and an asphalt surface layer. During the road construction process, the base soil layer and the gravel buffer layer are laid evenly, and the asphalt surface layer is sloped by laying different thicknesses. The most important gravel buffer layer does not evenly bear the pressure applied to the asphalt surface layer by vehicles, resulting in problems such as cracking and collapse of the highway. Summary of the Invention

[0004] The purpose of the present invention is to provide a municipal road construction equipment with a synchronous detection function to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a municipal road construction equipment with synchronous detection function, comprising a construction vehicle, wherein the construction vehicle is provided with a controller and a protective box, wherein a feed hopper and a stone drop plate are provided inside the protective box, a control mechanism is provided below the feed hopper, the stone drop plate is located below the feed hopper, one end of the stone drop plate extends out of the protective box, and a pair of drag rods are symmetrically connected to the end of the stone drop plate extending out of the protective box, a ground roller is connected between the pair of drag rods, the surface of the ground roller is rough, and a control mechanism is provided at the front of the construction vehicle. There is a dust collector, and a fan, a blade curtain, a detection mechanism, and several air ducts are arranged inside the dust collector. The blade curtain is located at the air outlet of the fan, and the detection mechanism and the several air ducts are all arranged at the end of the blade curtain away from the fan. The controller is connected to the positioning and navigation system, and the path information of the road is entered into the controller in advance. The controller controls the direction of travel of the construction vehicle. The construction vehicle lays gravel on the base soil layer to form a gravel buffer layer of the road. On one side of the construction vehicle, there is an engineering vehicle for placing gravel, and the construction vehicle places gravel into the feed hopper while moving.

[0006] Furthermore, the upper end of the feed hopper is connected to the outside of the protective box, and a plurality of upper partition plates are provided in the middle of the feed hopper. An upper compartment is formed between every two adjacent upper partition plates. The top of each upper partition plate is lower than the top of the feed hopper, and the bottom of each upper partition plate is flush with the bottom of the feed hopper. The control mechanism includes a drop control plate, which is slidably installed on the bottom of the feed hopper. The drop control plate controls the size of the bottom opening of the feed hopper. After the gravel enters the feed hopper, it is dispersed into all the upper compartments by the plurality of upper partition plates. The drop control plate controls the amount of gravel falling on the drop plate, and the gravel then slides along the drop plate to the base soil layer.

[0007] Furthermore, the control mechanism includes a first servo motor and a second servo motor, the first servo motor and the second servo motor are symmetrically arranged, the first servo motor and the second servo motor are both rotatably connected to the protective box, a first screw sleeve is installed on the motor shaft of the first servo motor, and a second screw sleeve is installed on the motor shaft of the second servo motor, and the first screw rod and the second screw rod are symmetrically arranged on one side of the blanking control plate close to the first servo motor and the second servo motor, the first screw rod and the second screw rod are both rotatably connected to the blanking control plate, the first screw rod is threadedly connected to the first screw rod sleeve, and the second screw rod is threadedly connected to the second screw rod sleeve, the first servo motor and the second servo motor are connected to the controller circuit, when paving a straight road, the construction vehicle paves the width of a lane in one stroke, and the middle of the road needs to be higher than the height of both sides, then the stone falling plate is close to the side of the road The amount of gravel falling on the side of the edge is less than the amount of gravel falling on the side of the stone drop plate near the middle of the road. The controller drives the first servo motor and the second servo motor to move simultaneously. The first servo motor drives the first screw sleeve to rotate, so that the first screw is retracted into the interior of the first screw sleeve, and the second servo motor drives the second screw sleeve to rotate, so that the second screw is pushed out toward the outside of the second screw sleeve. The first screw rod and the second screw rod pull the blanking control plate to tilt, so that the bottom of the upper compartment near the edge of the road is more blocked by the blanking control plate. The larger the opening opened by the blanking control plate at the bottom of the upper compartment near the middle of the road is, the larger the opening at the bottom of the upper compartment in the middle part changes in sequence, thereby ensuring that the amount of gravel falling from different upper compartments into the lower compartment at the same time is different and increases in sequence, and the thickness of gravel laid near the edge of the road is lower than the thickness of gravel laid near the center of the road.

[0008] Furthermore, the rockfall plate is formed by connecting three steel plates, an elastic bottom plate is provided in the middle of the rockfall plate, and a plurality of lower partition plates are provided on the rockfall plate. A lower compartment is provided between every two adjacent lower partition plates, and the number of the lower partition plates is the same as the number of the upper partition plates. The positions of the plurality of upper compartments correspond to the positions of the plurality of lower compartments one by one. When paving a curve, whether it is a left turn or a right turn, the road surface height of the large arc section on the outside of the curve needs to be higher than the road surface height of the small arc section on the inside of the curve. The controller calculates the curvature of the curve by Calculate the optimal inclination angle of the road surface, control the rotation of the first servo motor and the second servo motor to convert the road surface inclination angle into the inclination of the blanking control plate, and thus achieve the function of controlling the change in road surface height by controlling the amount of gravel falling from each lower compartment. There is a step-like difference in the height of the gravel falling from each lower compartment to the base soil layer. The ground roller rolls over the surface of the gravel under the drive of the drag rod. The rough texture on the surface of the ground roller prevents sliding from damaging the surface of the gravel. The ground roller uses its own weight to flatten the drop between each section of gravel to form a connecting transition.

[0009] Furthermore, a double crankshaft is provided in each corresponding upper compartment and lower compartment, each of the double crankshafts passes through the elastic bottom plate, and both ends of each double crankshaft are rotatably mounted with the protective box. An upper eccentric shaft and a lower eccentric shaft are provided in the middle of the double crankshaft, and the upper eccentric shaft is located in the upper compartment, and the lower eccentric shaft is located at the bottom of the stone drop plate. While laying gravel, the crank motor drives the small crank to rotate, and the small crank drives all the double crankshafts to rotate through the linkage rod. When each double crankshaft rotates, the upper eccentric shaft rotates in the center of the upper compartment, and the gravel passing through the position of the drop control plate is stirred and dispersed by fluctuations to prevent the gravel from getting stuck on the drop control plate, thereby accelerating the gravel discharge speed.

[0010] Furthermore, a crank motor is provided at the bottom of the rockfall plate, a small crank is installed on the crank motor, a linkage rod is provided on the small crank, the linkage rod is rotatably connected to each lower eccentric shaft, and two knocking short columns are provided on the double crankshaft, one of the knocking short columns is located in the lower compartment close to the elastic bottom plate, and the other knocking short column is located below the rockfall plate close to the elastic bottom plate. The double crankshaft drives the two knocking short columns to rotate at the same time, and the elastic bottom plate is tilted. Every time the double crankshaft rotates one circle, the two knocking short columns knock on the elastic bottom plate once in turn, and the elastic bottom plate vibrates continuously. The gravel sliding on the elastic bottom plate is distributed more evenly and flatly under the action of the vibration, and the gravel is more flat and even after being laid on the base soil layer.

[0011] Furthermore, the detection mechanism includes a plurality of detection tubes, and the plurality of detection tubes are evenly distributed in the dust collector. A metal telescopic drum is provided in each detection tube. The metal telescopic drum is in the shape of a bellows, and a small hole is provided at the bottom of the metal telescopic drum. The edge of the bottom of the metal telescopic drum is sealed and connected to the detection tube. A traction column is provided on the top of the traction column, and a round pin is provided on the top of the traction column. A lever and a sliding rheostat are also provided in the detection tube. The lever is rotatably installed in the detection tube, and a slide groove is provided at one end of the lever close to the traction column. The round pin is slidably installed in the slide groove, and a lever is provided at one end of the lever close to the sliding rheostat. The metal contact contacts the sliding rheostat, and the fan blows air in the direction of the construction vehicle to blow away the dust and garbage on the base soil layer to avoid affecting the paving quality of the gravel. A low-pressure area is formed under the detection tube. If there are pits on the surface of the base soil layer, there will be extra space for the pits under the dust collector. The airflow ejected by the fan slows down when passing through the pits, causing the air pressure in the low-pressure area under the detection tube to increase. The metal telescopic drum expands under the action of its own elasticity, the traction column moves upward, the round pin drives the lever to swing, and the lever drives the metal contact to move on the sliding rheostat. The metal contact and the sliding rheostat are connected to the controller through a circuit;

[0012] If there are bumps on the surface of the base soil layer, the airflow will speed up when passing through the bumps, the air pressure below the detection tube will continue to decrease, the metal telescopic drum will shrink, the traction column will move downward and change the position of the metal contact on the sliding rheostat through the lever. The controller can judge the surface flatness of the base soil layer by monitoring the current in each sliding rheostat. If there are serious bumps and unevenness, it is necessary to stop laying gravel and manually process the base soil layer road surface first.

[0013] Furthermore, a plurality of the air ducts are evenly arranged in the dust collector, and the diameters of the air ducts increase successively from the middle of the dust collector to both sides. The air ducts guide the wind blown out by the fan to the upper part of the dust collector. The air ducts with large diameters guide a large airflow, and the air ducts with small diameters guide a small airflow, that is, the airflow blown forward from the middle of the construction vehicle is large, and the airflow becomes smaller as it moves to both sides, so that the garbage or layer soil on the base soil layer is blown to both sides and will not accumulate in the front.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The first servo motor and the second servo motor control the first screw rod and the second screw rod to pull the blanking control plate to tilt, so that the bottom of the upper compartment close to the edge of the road is blocked more by the blanking control plate, and the opening opened by the blanking control plate at the bottom of the upper compartment close to the middle of the road is larger, and the size of the opening at the bottom of the upper compartment in the middle part changes successively, thereby ensuring that the amount of gravel falling from different upper compartments to the lower compartment at the same time is different and increases successively, so as to control the falling amount of gravel in each lower compartment and achieve the function of controlling the change in road surface height.

[0016] 2. The fan blows air in the direction of the construction vehicle to blow away the dust and garbage on the base soil layer. At the same time, a low-pressure area is formed under the detection tube. If there are pits or protrusions on the surface of the base soil layer, the air pressure under the detection tube will continue to decrease. The metal telescopic drum will contract, and the air pressure in the low-pressure area under the detection tube will increase, converting the metal telescopic drum into changes in the current on several sliding resistors, thereby achieving the function of monitoring the flatness of the road surface.

The controller 2 controls the travel direction of the construction vehicle 1. The construction vehicle 1 lays gravel on the base soil layer to form a gravel buffer layer of the road. There is an engineering vehicle for dropping gravel on one side of the construction vehicle 1. The construction vehicle 1 drops gravel into the feed hopper 4 while moving. After the gravel enters the feed hopper 4, it is dispersed into all the upper compartments by the five upper partition plates 5. The drop control plate 6 controls the amount of gravel falling on the stone drop plate 9, and the gravel then slides along the stone drop plate 9 to the base soil layer.

[0029] The upper end of the feed hopper 4 is connected to the outside of the protective box 3. Five upper partition plates 5 are provided in the middle of the feed hopper 4. An upper compartment is formed between every two adjacent upper partition plates 5. The top of each upper partition plate 5 is lower than the top of the feed hopper 4. The bottom of each upper partition plate 5 is flush with the bottom of the feed hopper 4. The control mechanism includes a blanking control plate 6. The blanking control plate 6 is slidably mounted on the bottom of the feed hopper 4. The blanking control plate 6 controls the size of the bottom opening of the feed hopper 4. The control mechanism includes a first servo motor 701 and a second servo motor 702. The first servo motor 701 and the second servo motor 702 are symmetrical. The first servo motor 701 and the second servo motor 702 are both rotatably connected to the protective box 3, a first screw sleeve is installed on the motor shaft of the first servo motor 701, and a second screw sleeve is installed on the motor shaft of the second servo motor 702. The first screw rod 801 and the second screw rod 802 are symmetrically arranged on one side of the blanking control plate 6 close to the first servo motor 701 and the second servo motor 702. The first screw rod 801 and the second screw rod 802 are both rotatably connected to the blanking control plate 6, the first screw rod 801 is threadedly connected to the first screw sleeve, and the second screw rod 802 is threadedly connected to the second screw sleeve.

[0030] The first servo motor 701 and the second servo motor 702 are connected to the controller 2 circuit. When paving a straight road, the construction vehicle 1 paves the width of a lane in one stroke. The middle of the road needs to be higher than the height of both sides. Then the amount of gravel dropped by the stone drop plate 9 close to the edge of the road is less than the amount of gravel dropped by the stone drop plate 9 close to the middle of the road. The controller 2 drives the first servo motor 701 and the second servo motor 702 to move at the same time. The first servo motor 701 drives the first screw sleeve to rotate, so that the first screw 801 is retracted into the inside of the first screw sleeve, and the second servo motor 702 drives the second servo motor 701 to rotate. The second screw sleeve rotates, causing the second screw 802 to be pushed out of the second screw sleeve, and the first screw 801 and the second screw 802 pull the blanking control plate 6 to tilt, so that the bottom of the upper compartment near the edge of the road is more blocked by the blanking control plate 6, and the opening opened by the blanking control plate 6 at the bottom of the upper compartment near the middle of the road is larger, and the size of the opening at the bottom of the upper compartment in the middle part changes successively, thereby ensuring that the amount of gravel falling from different upper compartments into the lower compartment at the same time is different and increases successively, and the thickness of the gravel laid near the edge of the road is lower than the thickness of the gravel laid near the center of the road.

[0031] The rockfall plate 9 is connected by three steel plates. An elastic bottom plate 11 is provided in the middle of the rockfall plate 9. The rockfall plate 9 is provided with five lower partition plates 10. There is a lower compartment between every two adjacent lower partition plates 10. The number of lower partition plates 10 is the same as the number of upper partition plates 5. The positions of the five upper compartments correspond to the positions of the five lower compartments. When paving a curve, whether it is a left turn or a right turn, the road surface height of the large arc section on the outside of the curve needs to be higher than the road surface height of the small arc section on the inside of the curve. The controller 2 calculates the optimal inclination angle of the road surface by calculating the curvature of the curve. Degree, controls the rotation of the first servo motor 701 and the second servo motor 702 to convert the road surface inclination angle into the inclination of the material dropping control plate 6, thereby controlling the amount of gravel dropped from each lower compartment to achieve the function of controlling the change in road surface height. There is a step-like difference in the height of the gravel dropped from each lower compartment to the base soil layer. The ground roller 17 rolls over the surface of the gravel under the drive of the drag rod 16. The rough texture on the surface of the ground roller 17 prevents sliding from damaging the surface of the gravel. The ground roller 17 uses its own weight to flatten the drop between each section of gravel to form a connecting transition.

[0032] A double crankshaft 14 is provided in each corresponding upper compartment and lower compartment, and each double crankshaft 14 passes through the elastic bottom plate 11. Both ends of each double crankshaft 14 are rotatably mounted with the protective box 3. An upper eccentric shaft and a lower eccentric shaft are provided in the middle of the double crankshaft 14. The upper eccentric shaft is located in the upper compartment, and the lower eccentric shaft is located at the bottom of the stone falling plate 9. A crank motor 12 is provided at the bottom of the stone falling plate 9. A small crank is installed on the crank motor 12, and a linkage rod 13 is provided on the small crank. The linkage rod 13 is rotatably connected with each lower eccentric shaft. Two knocking short columns 15 are also provided on the double crankshaft 14. One knocking short column 15 is located in the lower compartment near the elastic bottom plate 11, and the other knocking short column 15 is located below the stone falling plate 9 near the elastic bottom plate 11. At the same time, the crank motor 12 drives the small crank to rotate, and the small crank drives all the double crankshafts 14 to rotate through the linkage rod 13. When each double crankshaft 14 rotates, the upper eccentric shaft rotates in the center of the upper compartment, and the gravel passing through the position of the blanking control plate 6 is subjected to fluctuation and stirring to prevent the gravel from getting stuck on the blanking control plate 6, thereby accelerating the gravel discharge speed. The double crankshaft 14 simultaneously drives the two knocking short columns 15 to rotate, and the elastic bottom plate 11 is tilted. Every time the double crankshaft 14 rotates one circle, the two knocking short columns 15 knock on the elastic bottom plate 11 once in turn, and the elastic bottom plate 11 vibrates continuously. The gravel sliding on the elastic bottom plate 11 is distributed more evenly and flatly under the action of vibration, and the gravel is more flat and even after being paved on the base soil layer.

[0033] The detection mechanism includes a plurality of detection tubes 21, and the plurality of detection tubes 21 are evenly distributed in the dust collector 18. A metal telescopic drum 22 is provided in each detection tube 21. The metal telescopic drum 22 is in the shape of a bellows. A small hole is provided at the bottom of the metal telescopic drum 22. The edge of the bottom of the metal telescopic drum 22 is sealed and connected to the detection tube 21. A traction column 23 is provided on the top of the metal telescopic drum 22. A round pin is provided on the top of the traction column 23. A lever 24 and a sliding rheostat 25 are also provided in the detection tube 21. The lever 24 is rotatably installed in the detection tube 21. A slide groove is provided at one end of the lever 24 close to the traction column 23. The round pin is slidably installed in the slide groove. A metal Contact, the metal contact contacts the sliding rheostat 25, and the fan 19 blows air in the direction of the construction vehicle 1 to blow away the dust and garbage on the base soil layer to avoid affecting the paving quality of the gravel. A low-pressure area is formed under the detection tube 21. If there are pits on the surface of the base soil layer, there will be extra space for the pits under the dust collector 18. The airflow ejected by the fan 19 slows down when passing through the pits, causing the air pressure in the low-pressure area under the detection tube 21 to increase. The metal telescopic drum 22 is stretched open by its own elasticity, and the traction column 23 moves upward. The round pin drives the lever 24 to swing, and the lever 24 drives the metal contact to move on the sliding rheostat 25. The metal contact and the sliding rheostat 25 are connected to the controller 2 through the circuit;

[0034] If there are bulges on the surface of the base soil layer, the airflow speeds up when passing through the bulges, the air pressure below the detection tube 21 continues to decrease, the metal telescopic drum 22 contracts, the traction column 23 moves downward and changes the position of the metal contact on the sliding rheostat 25 through the lever 24. The controller 2 can judge the surface flatness of the base soil layer by monitoring the current in each sliding rheostat 25. If serious unevenness occurs, it is necessary to stop laying gravel and manually process the base soil layer road surface first.

[0035] A plurality of air ducts 26 are evenly distributed in the dust collector 18. The diameters of the air ducts 26 increase successively from the middle of the dust collector 18 toward both sides. The air ducts 26 guide the wind blown out by the fan 19 toward the upper part of the dust collector 18. The air ducts 26 with large diameters guide a large airflow, and the air ducts 26 with small diameters guide a small airflow. That is, the airflow blown forward from the middle of the construction vehicle 1 is large, and the airflow becomes smaller toward the sides, so that the garbage or layer soil on the base soil layer is blown to both sides and will not accumulate in the front.

[0036] The working principle of the present invention is as follows: when using the construction equipment of the present invention to lay gravel, the path information of the road is entered into the controller 2 in advance, and the controller 2 controls the direction of travel of the construction vehicle 1. An engineering vehicle for dropping gravel is arranged in parallel on one side of the construction vehicle 1. The construction vehicle 1 drops gravel into the feed hopper 4 while moving. The first servo motor 701 and the second servo motor 702 are connected to the circuit of the controller 2. When paving a straight road, the construction vehicle 1 lays the width of a lane in one stroke. The middle of the road needs to be higher than the height of both sides. Then the amount of gravel dropped from the side of the stone drop plate 9 close to the edge of the road is less than the amount of gravel dropped from the side of the stone drop plate 9 close to the middle of the road. The controller 2 drives the first servo motor 701 and the second servo motor 702 to move simultaneously. The servo motor 701 drives the first screw sleeve to rotate, so that the first screw 801 retracts into the interior of the first screw sleeve, and the second servo motor 702 drives the second screw sleeve to rotate, so that the second screw 802 is pushed out to the outside of the second screw sleeve. The first screw 801 and the second screw 802 pull the blanking control plate 6 to tilt, so that the bottom of the upper compartment near the edge of the road is more blocked by the blanking control plate 6, and the opening opened by the blanking control plate 6 at the bottom of the upper compartment near the middle of the road is larger, and the size of the opening at the bottom of the upper compartment in the middle part changes successively, thereby ensuring that the amount of gravel falling from different upper compartments into the lower compartment at the same time is different and increases successively, and the thickness of the gravel laid near the edge of the road is lower than the thickness of the gravel laid near the center of the road.

[0037] When paving a curve, whether it is a left turn or a right turn, the road surface height of the large arc section on the outside of the curve needs to be higher than the road surface height of the small arc section on the inside of the curve. The controller 2 calculates the optimal inclination angle of the road surface by calculating the curvature of the curve, and controls the rotation of the first servo motor 701 and the second servo motor 702 to convert the road surface inclination angle into the inclination of the blanking control plate 6, thereby achieving the function of controlling the change in road surface height by controlling the amount of gravel falling from each lower compartment. There is a step-like difference in the height of the gravel falling from each lower compartment to the base soil layer. The ground roller 17 rolls over the surface of the gravel under the drive of the drag rod 16. The rough texture on the surface of the ground roller 17 prevents sliding from damaging the surface of the gravel. The ground roller 17 uses its own weight to flatten the drop between each section of gravel to form a connecting transition.

[0038] While laying gravel, the crank motor 12 drives the small crank to rotate, and the small crank drives all the double crankshafts 14 to rotate through the linkage rod 13. When each double crankshaft 14 rotates, the upper eccentric shaft rotates in the center of the upper compartment, and the gravel passing through the position of the blanking control plate 6 is subjected to wave stirring to disperse, thereby preventing the gravel from getting stuck on the blanking control plate 6, thereby accelerating the gravel unloading speed. The double crankshaft 14 simultaneously drives the two knocking short columns 15 to rotate, and the elastic bottom plate 11 is tilted. For every rotation of the double crankshaft 14, the two knocking short columns 15 knock on the elastic bottom plate 11 once in turn, and the elastic bottom plate 11 vibrates continuously. The gravel sliding on the elastic bottom plate 11 is distributed more evenly and flatly under the action of vibration, and the gravel is more flat and even after being paved on the base soil layer.

[0039] The fan 19 blows air in the direction of the construction vehicle 1 to blow away the dust and garbage on the base soil layer to avoid affecting the paving quality of the gravel. A low-pressure area is formed below the detection tube 21. If there are pits on the surface of the base soil layer, there will be extra space for the pits below the dust collector 18. The airflow ejected by the fan 19 slows down when passing through the pits, causing the air pressure in the low-pressure area below the detection tube 21 to increase. The metal telescopic drum 22 is expanded under the action of its own elasticity, and the traction column 23 moves upward. The round pin drives the lever 24 to swing, and the lever 24 drives the metal contact to move on the sliding rheostat 25. The metal contact and the sliding rheostat 25 are connected to the controller 2 through the circuit.

[0040] If there are bulges on the surface of the base soil layer, the airflow speeds up when passing through the bulges, the air pressure below the detection tube 21 continues to decrease, the metal telescopic drum 22 contracts, the traction column 23 moves downward and changes the position of the metal contact on the sliding rheostat 25 through the lever 24. The controller 2 can judge the surface flatness of the base soil layer by monitoring the current in each sliding rheostat 25. If serious unevenness occurs, it is necessary to stop laying gravel and manually process the base soil road surface. Several air ducts 26 guide the wind blown out by the fan 19 to the upper part of the dust collector 18. The air duct 26 with a large diameter guides a large airflow, and the air duct 26 with a small diameter guides a small airflow, that is, the airflow blown forward from the middle of the construction vehicle 1 is large, and the airflow becomes smaller as it goes to the sides, so that the garbage or layer soil on the base soil layer is blown to both sides and will not accumulate in the front.
