Description

Technical Field

[0001] The present invention relates to the technical field of road paving, in particular to road paving equipment for municipal engineering. Background Art

[0002] Municipal engineering refers to municipal infrastructure construction projects, including roads, bridges, water supply, drainage, power supply, public transportation and other aspects. Among them, roads are an important part of municipal infrastructure. During the road paving process, asphalt concrete is usually laid by an asphalt paver. The asphalt mixture is evenly spread on the road base, and then preliminary vibration and leveling are carried out to ensure the quality and service life of the asphalt pavement.

[0003] When an asphalt paver is used to lay asphalt mixture for a road, hot asphalt mixture is poured into the hopper at the front of the paver. The scraper conveyor at the bottom of the hopper conveys the mixture backward to the spiral spreader. The spiral spreader spreads the mixture evenly to both sides along the paving width to form a continuous material strip, and the mixture is vibrated and leveled by a vibrator and an ironing board. However, when paving at a turning position of the road, the paving speed is reduced and the paving thickness of the asphalt mixture is increased. The lateral force generated on the road surface when the vehicle turns will increase, resulting in stress concentration on the road surface. Therefore, the paving thickness needs to be increased at the turning position to disperse the stress, so as to reduce rutting deformation and extend the service life of the road surface in the turning section. However, the paving thickness of the asphalt mixture of the asphalt paver cannot be adjusted automatically according to the turning radius of the road turning section, and the feed amount of the asphalt paver cannot be adjusted automatically according to the changes in the paving speed and paving thickness when turning. There may be uneven feeding, which affects the paving quality of the road. For this reason, we propose a road paving equipment for municipal engineering. Summary of the Invention

[0036] The road paving machine further comprises: a detection component 3, which is arranged on one side of the paver body 11 and is used to detect the turning speed of the paver body 11 when paving at a turning position of the road;

[0037] The regulating assembly 4 is arranged on one side of the detecting assembly 3. The regulating assembly 4 automatically adjusts the feeding amount of the conveyor 14 according to the turning speed of the paver body 11 detected by the detecting assembly 3;

[0038] The executive component 5 is arranged on one side of the adjustment component 4, and the executive component 5 automatically adjusts the paving thickness of the paver body 11 according to the turning radius of the turning section;

[0039] Auxiliary component 2 is arranged on one side of the paver body 11. The auxiliary component 2 adjusts the paving thickness according to the execution component 5 when turning, and then further adjusts the feeding amount of the conveyor 14 through the adjustment component 4.

[0040] When the asphalt paver body 11 is used to pave the asphalt mixture of the road, the asphalt mixture is poured into the hopper on the front side of the paver body 11, and the asphalt mixture is transported to the rear side by the conveyor 14 at the bottom of the hopper, so that the transported mixture is paved by the paver body 11; when the paver body 11 is used to pave the turning position of the road, the turning speed of the paver body 11 during paving can be detected by the detection component 3, and according to the turning speed of the paver body 11 detected by the detection component 3, the feeding amount of the conveyor 14 is adjusted by the adjustment component 4, so that the amount of asphalt mixture transported by the conveyor 14 can be automatically adjusted according to the turning speed of the paver body 11 during paving. Through the execution component 5, the paving thickness of the paver body 11 can be automatically adjusted according to the turning radius of the paver body 11 when paving, so as to adaptively increase the paving thickness of the road asphalt mixture at the turning position of the road, disperse the stress generated on the road surface when the vehicle turns, and extend the service life of the road surface in the turning section. Through the auxiliary component 2, the paving thickness can be adjusted according to the execution component 5 when turning, and the feeding amount of the conveyor 14 can be further adjusted through the adjustment component 4, so that the feeding amount of the conveyor 14 can be further adjusted according to the change of the paving thickness when paving the turning section, thereby adaptively adjusting the feeding amount, improving the applicability of the paver body 11 to road paving, and improving the paving quality of the road.

[0041] The auxiliary component 2 includes a mounting shell 21 fixed to the paver body 11, an electric telescopic rod 22 is fixed to the bottom end of the inner side of the mounting shell 21, the telescopic end of the electric telescopic rod 22 is fixed to a mounting seat 23, the telescopic end of the first telescopic rod 24 is symmetrically fixed to the lower side of the mounting seat 23, the fixed end of the first telescopic rod 24 is fixed to the bottom end of the mounting shell 21, the first telescopic rod 24 can guide the up and down movement of the mounting seat 23, a first switch 25 is installed on one side of the mounting seat 23, a protective cover 26 is fixed to one side of the paver body 11, the protective cover 26 is located on the upper side of the mounting shell 21, and can protect the mounting shell 21.

[0042] A pressure block 212 is provided on one side of the mounting seat 23, and one side of the pressure block 212 is set as an arc-shaped end surface to facilitate the pressing of the first switch 25. Initially, the pressure block 212 presses the first switch 25. Two tooth rods 211 that are movable through the bottom end of the mounting shell 21 are fixed on the lower side of the pressure block 212. A connecting rod 29 is fixed on the lower end of the two tooth rods 211. A connecting block 28 is fixed on the end of the connecting rod 29 away from the tooth rod 211. The connecting block 28 is slidably arranged with the movable frame 13. Accordingly, a limiting groove adapted to the connecting block 28 is provided on the upper side of the movable frame 13. The connecting block 28 is slidably arranged along the limiting groove so as not to hinder the movement of the movable frame 13 to both sides when the paving width is adjusted, and the connecting block 28 can move up and down with the movable frame 13. The telescopic end of the second telescopic rod 210 is fixed on the upper side of the connecting block 28, and the fixed end of the second telescopic rod 210 is fixed with a fixing part 27. The lower end of the fixing part 27 is fixed to the paving frame 12.

[0043] A support member 213 is provided on the upper side of the mounting seat 23, and the telescopic end of the third telescopic rod 215 is symmetrically fixed on the lower side of the support member 213. The fixed end of the third telescopic rod 215 is fixed to the bottom end of the mounting shell 21. The third telescopic rod 215 can guide the up and down movement of the support member 213. A connecting shell 214 is fixed on the lower side of the support member 213. The connecting shell 214 is located between the two gear rods 211. A first electromagnetic block 216 is fixed in the connecting shell 214. A tooth block 217 that is attracted to the first electromagnetic block 216 is symmetrically slidably provided in the connecting shell 214. The tooth block 217 cooperates with the gear rod 211. The inner sides of the two tooth blocks 217 are symmetrically fixed with first springs 218 fixed to the connecting shell 214.

[0044] When the paver body 11 is used to pave the road, the paving width of the paver body 11 can be adjusted by adjusting the telescopic distance of the movable frames 13 on both sides. The paving thickness of the asphalt mixture on the road can be adjusted by controlling the up and down movement of the movable frames 13. By inputting relevant parameters such as the paving width and paving thickness, the conveying speed of the asphalt mixture by the conveyor 14 can be controlled to be adjusted at the initial time, so that the feeding amount of the conveyor 14 matches the current paving width and paving thickness (this is the existing technology). When adjusting the paving thickness at the initial time, the upward movement of the movable frame 13 will drive the connecting block 28 and the connecting rod 29 to move upward synchronously, and then drive the gear rod 211 and the pressure block 212 to move upward, so that the pressure block 212 no longer presses the first switch 25. At this time, the first electromagnetic block 216 is in the energized state, which will produce an adsorption effect on the gear blocks 217 on both sides. The tooth blocks 217 on both sides are in a state of not being engaged with the tooth rods 211 on both sides, and the first spring 218 is compressed. Therefore, during this process, the upward movement of the tooth rod 211 will not drive the connecting shell 214 and the support member 213 to move upward. By controlling the operation of the electric telescopic rod 22, the telescopic end of the electric telescopic rod 22 drives the mounting seat 23 to move upward, and at the same time drives the support member 213, the detection component 3, the adjustment component 4 and the execution component 5 to move upward. When the first switch 25 moves upward to be pressed by the pressed block 212, the electric telescopic rod 22 will be controlled to stop working, and the first electromagnetic block 216 will be controlled to be powered off. Under the elastic force of the first spring 218, the two tooth blocks 217 are moved to both sides respectively until they are engaged and fixed with the tooth rods 211 on both sides, so that the detection component 3, the adjustment component 4 and the execution component 5 can be adjusted to the corresponding positions according to the initial adjustment of the paving thickness.

[0045] The detection component 3 includes two shells 31 fixed on the upper side of the support member 213, and a second electromagnetic block 32 is fixed in the shell 31. A wheel speed sensor is provided at the track drive wheel shaft of the paver body 11, and a magnetoelectric wheel speed sensor is selected. The installation of the wheel speed sensor is an existing public technology, and there are two wheel speed sensors, which correspond to the track drive wheels on both sides of the paver body 11 respectively. The two wheel speed sensors are electrically connected to the two second electromagnetic blocks 32 respectively. A moving block 33 is slidably provided in the shell 31, and a first magnetic block 34 that repels the second electromagnetic block 32 is fixed on the lower side of the moving block 33, and a second spring 36 fixed to the shell 31 is fixed on the upper side of the moving block 33.

[0046] A fixed rod 35 that movably passes through the top of the shell 31 is fixed on the upper side of the moving block 33. Slide rods 37 are rotatably provided on the upper sides of the two fixed rods 35. A rotating rod 38 is slidably provided on one side of the two slide rods 37. A rotating part 39 is rotatably provided in the middle of the rotating rod 38. When the fixed rods 35 on both sides move up and down, the slide rods 37 on both sides slide outward or inward along the two sides of the rotating rod 38 respectively.

[0047] The adjustment assembly 4 includes a bracket 41 fixed on the upper side of the mounting base 23, a metal strip 42 and a guide rod 43 fixed on the inner side of the bracket 41, a metal contact 44 slidingly arranged on the guide rod 43 and slidingly arranged with the metal strip 42, the resistance of the metal strip 42 located on the upper side of the metal contact 44 is connected to the circuit, and the rotating part 39 is fixed to the metal contact 44.

[0048] When the paver body 11 is paving a straight section of road, the rotation speed of the crawler drive wheels on both sides of the paver body 11 is detected by the wheel speed sensors on both sides. When the paver body 11 is paving at a faster speed, the current in the circuit connected to the wheel speed sensor will be relatively large, so that the second electromagnetic block 32 will have a greater repulsive effect on the first magnetic block 34, causing the movable block 33 and the fixed rod 35 to move up a greater distance, and the second spring 36 will be compressed, thereby causing the sliding rod 37, the rotating rod 38 and the rotating member 39 to move up a greater distance, driving the metal contact piece 44 to move up a greater distance, so that the resistance of the metal strip 42 connected to the circuit is relatively reduced, thereby increasing the opening and closing degree of the hydraulic valve of the conveyor 14 to a relatively large extent, so that more oil enters the motor, thereby increasing the conveying speed of the conveyor 14 for the asphalt mixture and the feeding amount of the conveyor 14 to match the faster paving speed, or increasing the rotation speed of the drive motor of the conveyor 14, thereby increasing the feeding amount of the conveyor 14;

[0049] When the paver body 11 turns from a straight section of road to a curved section of road, the paving speed of the paver body 11 will decrease, so that the repulsive effect of the two second electromagnetic blocks 32 on the first magnetic block 34 will be reduced. Under the elastic force of the second spring 36, the movable block 33 and the fixed rod 35 will move downward. When the paver body 11 turns, there will be a certain speed difference between the rotation speeds of the crawler drive wheels on the inner and outer sides, so that the repulsive forces generated by the two second electromagnetic blocks 32 will be different, causing the sliding rods 37 and the rotating rod 38 on both sides to deflect and slide along the rotating rod 38. The rotating part 39 is located in the middle of the rotating rod 38, and the height of the rotating part 39 after it is driven downward can be adjusted. The position is the middle of the height position of the moving blocks 33 on both sides after moving downward, to indicate the change in moving distance caused by the turning speed of the paver body 11. The downward movement of the rotating part 39 can drive the downward movement of the metal contact piece 44, so that the resistance of the metal strip 42 connected to the circuit increases relative to the straight section of the road, thereby reducing the feeding amount of the conveyor 14, so that the feeding amount of the conveyor 14 can be automatically adjusted according to the turning speed of the paver body 11 during paving; when the paver body 11 turns from the turning section of the road to the straight section of the road again, similarly, through the detection of the detection component 3 and the adjustment of the adjustment component 4, the feeding amount of the conveyor 14 can be matched with the current paving speed of the paver body 11.

[0050] The actuator 5 includes a third electromagnetic block 51 fixed on the upper side of the mounting seat 23. An angle sensor is provided at the joystick transmission shaft of the paver body 11, and can be selected as a magnetic angle sensor. The installation of the angle sensor is an existing public technology. The angle sensor is electrically connected to the third electromagnetic block 51. A fixed plate 510 is fixed on the upper side of the mounting seat 23, and a limit rod 54 fixed to the mounting seat 23 is symmetrically fixed on the lower side of the fixed plate 510. A mounting member 52 slidingly arranged with the limit rod 54 is provided on the upper side of the third electromagnetic block 51, and a second magnetic block 53 that repels the third electromagnetic block 51 is fixed on the lower side of the mounting member 52. A third spring 55 fixed to the fixed plate 510 is fixed on the upper side of the mounting member 52.

[0051] Two sliders 56 are symmetrically slidably provided on one side of the mounting member 52. The two sliders 56 are respectively located on the upper and lower sides of the pressure block 212. The sides of the two sliders 56 that are away from each other are respectively fixed with fourth springs 59 fixed to the mounting member 52. The sides of the two sliders 56 that are close to each other are respectively installed with second switches 57. Initially, the pressure block 212 presses the second switches 57 on both sides. One side of the mounting member 52 is symmetrically provided with sliding grooves 58 that are adapted to the sliders 56. The two sliders 56 are respectively slidably arranged along the upper and lower sliding grooves 58, which can guide the up and down sliding of the sliders 56.

[0052] When the paver body 11 is paving a curved road, if the turning radius of the road is small, the steering angle of the paver body 11 will be larger, the turning angle detected by the angle sensor will be larger, the current in the circuit connected to the angle sensor will be larger, and the third electromagnetic block 51 will have a larger repulsive effect on the second magnetic block 53, so that the mounting member 52 moves up a larger distance, the third spring 55 is compressed, and the upward movement of the mounting member 52 can make the pressure block 212 no longer press the second switch 57 on the upper side, so that the paver body 11 can control the movable frame 13 to move up, and drive the pressure block 212 to move up. When the pressing block 212 moves upward to press the second switch 57 on the upper side, the movable frame 13 is controlled to stop moving, thereby correspondingly increasing the paving thickness of the paver body 11. When the turning radius of the road is relatively smaller, the angle detected by the angle sensor can be relatively larger, and then the upward movement distance of the mounting member 52 can be relatively large, so that the paving thickness can be increased relatively more. When the turning radius of the road is smaller, the stress on the road surface when the vehicle turns is relatively large, and the paving thickness of the road needs to be increased relatively more, so that it can be adapted to the adjustment of the paving thickness by the actuator 5.

[0053] By means of the actuator component 5, when the paver body 11 controls the movable frame 13 to move upward, the connecting block 28, the connecting rod 29 and the two gear rods 211 can be driven upward. Through the engagement and fixing of the gear blocks 217 on both sides with the gear rods 211 on both sides, the connecting shell 214 and the support member 213 can be driven upward, thereby causing the detection component 3 to move upward, causing the metal contact piece 44 to move upward, reducing the resistance of the metal strip 42 in the circuit, and thereby increasing the feeding amount of the conveyor 14 to match the increase in paving thickness. Thus, the feeding amount of the conveyor 14 can be further adaptively adjusted according to the change in paving thickness during paving of the turning section, thereby improving the applicability of the paver body 11 to road paving and improving the paving quality of the road.

[0054] When the paver body 11 gradually turns from the curved section of the road to the straight section of the road, the steering angle of the paver body 11 gradually decreases, so that the turning angle detected by the angle sensor gradually decreases, and the repulsive effect of the third electromagnetic block 51 on the second magnetic block 53 is reduced. Under the elastic force of the third spring 55, the mounting member 52 moves downward, so that the pressure block 212 no longer presses the lower second switch 57, which will cause the paver body 11 to control the movable frame 13 to move downward. When the pressure block 212 moves down to press the lower second switch 57, the movable frame 13 will be controlled to stop moving downward, thereby restoring the paving thickness of the straight section of the road; after the road is paved, the first electromagnetic block 216 is controlled to be energized to generate an adsorption effect on the two tooth blocks 217, so that the two tooth blocks 217 are separated from the tooth rods 211 on both sides, and the telescopic end of the electric telescopic rod 22 is controlled to drive the mounting seat 23 to move downward for reset.

[0055] Example 2

[0056] A pressing member 61 is fixedly provided in the middle of the rotating rod 38 , and a third switch 62 is installed on the upper side of the rotating member 39 . One side of the pressing member 61 is set as an arc-shaped end surface to facilitate pressing the third switch 62 . An alarm 63 is installed on one side of the mounting shell 21 .

[0057] When the paver body 11 is paving a curved section of road, the inclination of the rotating rod 38 will cause the pressing member 61 to no longer press the third switch 62. When the paver body 11 turns from a curved section of road to a straight section of road, there will no longer be a speed difference between the speeds of the crawler drive wheels on both sides of the paver body 11. The rotating rod 38 will change from the inclined state during the turn to the straight state, causing the pressing member 61 to press the third switch 62 again. When the paver body 11 turns from a curved section of road to a straight section of road, the angle sensor will no longer detect the change in the steering angle of the paver body 11, causing the mounting member 52 to move downward under the action of the third spring 55. The paver body 11 controls the movable frame 13 to move down to the paving thickness of the straight section of the road, so that the pressure block 212 moves down and resets to press the first switch 25 again. At this time, the alarm 63 will not sound an alarm. If one of the third switch 62 and the first switch 25 is not pressed, the alarm 63 will be controlled to sound an alarm. At this time, the detection component 3 or the execution component 5 may have a fault. For example, the second spring 36, the second electromagnetic block 32 or the third spring 55, the third electromagnetic block 51, etc. have deviations due to long-term use. At this time, the staff can be reminded to check to ensure normal use.
