Description

Technical Field

[0002] Roads and bridges are generally composed of several parts, such as roadbed, pavement, bridges, tunnel engineering and traffic engineering facilities. The roadbed is a linear structure built with soil or stone. It bears its own rock and soil weight and the gravity of the pavement, as well as the driving load transmitted by the pavement, and is an important part of the entire road structure. Pavement engineering: The pavement is a layered structure that is paved on the roadbed of a highway with various road construction materials or mixtures for vehicles to travel. Its function is to ensure that vehicles can run on the road in all weather conditions, stably, at high speed, comfortably, safely and economically.

[0003] After municipal roads have been in operation for a period of time, pavement engineering often suffers from wear and tear. Severely damaged pavements often need to be repaved. However, there will be overlapping parts between municipal roads and urban pipe networks, that is, it is necessary to reserve wellheads connected to the urban pipe network on municipal roads. When paving new pavement, it is necessary to bypass the wellheads that have been built, and use manual paving methods near the wellheads. Automated paving cannot be achieved in this area, which reduces the efficiency of road construction. Therefore, a road and bridge construction device is urgently needed to solve this problem.

[0059] A plurality of cameras arranged side by side are mounted on the camera mounting frame 8, the plurality of cameras are electrically connected to the control unit, and the plurality of cameras correspond one to one with the plurality of discharge ports.

[0060] When in use, the pumped concrete is loaded into the hopper assembly, and after moving to the designated paving position through the vehicle body 1, it moves along the extension direction of the roadbed. The pneumatic drive unit and the control unit cooperate to control the unloading assembly to pave the pumped concrete on the road surface, and then the vibrator 5 and the scraping assembly are used to vibrate and scrape. During the movement of the vehicle body 1, since the camera mounting frame 8 is located in front of the moving direction of the unloading assembly, the road conditions can be pre-photographed by each camera installed on the camera mounting frame 8 and fed back to the control unit. The control unit confirms the boundary of the manhole cover according to the images captured by each camera, and controls the unloading port in the manhole cover area to be closed and the unloading port outside the manhole cover area to be opened. There is no need to avoid the manhole area, and the material can be paved back and forth directly according to the designed route, which greatly improves the paving efficiency.

[0061] Further optimized solution, the hopper assembly includes a concrete cargo box 2, the concrete cargo box 2 is fixedly connected to the top of the vehicle body 1, the top of the concrete cargo box 2 is detachably connected with a sealing cover plate 3, the sealing cover plate 3 is sealed with the top of the concrete cargo box 2, the middle of the bottom of the concrete cargo box 2 is connected to the feeding end of the material discharge assembly, the concrete cargo box 2 is fixedly connected with two slopes 18, the two slopes 18 are arranged on both sides of the feeding end of the material discharge assembly, and the bottom end of the slope 18 is arranged close to the feeding end of the material discharge assembly;

[0062] The seat box 4 is located on the side of the concrete cargo box 2 close to the front end of the vehicle body 1 in the direction of travel. An air intake channel 14 is provided in the side wall of the concrete cargo box 2 close to the seat box 4. An exhaust channel 16 and a return air channel 32 are provided in the side wall of the concrete cargo box 2 away from the seat box 4. The air outlet end of the air intake channel 14 and the air intake end of the exhaust channel 16 are connected through a second connecting pipe 15. The air intake end of the air intake channel 14 is connected to the pneumatic drive unit.

[0063] The air outlet end of the exhaust channel 16 is connected to the air inlet end of the vibrating rod 5 through the connecting hose 17 , and the air inlet end of the return air channel 32 is connected to the air outlet end of the vibrating rod 5 through the exhaust hose 29 .

[0064] The pumped concrete is loaded into the concrete cargo box 2. Since the pumped concrete has good fluidity, it is convenient to move to the feeding end of the lower feeding assembly under the action of its own weight. The concrete cargo box 2 is sealed with a sealing cover plate 3, which covers the open top of the concrete cargo box 2 and forms a closed space in the concrete cargo box 2 through a sealing ring. Subsequently, the pneumatic drive unit is started, and part of the gas is used to control the opening and closing of the discharge port, and the other part of the gas enters the vibrating rod 5 through the air inlet channel 14, the second connecting pipe 15, the exhaust channel 16 and the connecting hose 17 in turn to cause it to vibrate, and then returns to the top of the inner side of the concrete cargo box 2 through the exhaust hose 29 and the return air channel 32. Since the concrete cargo box 2 is a sealed chamber, as the air pressure at the top of the concrete cargo box 2 increases, the pumped concrete can be accelerated to move to the lower feeding assembly, and the slopes 18 on both sides of the lower feeding assembly also facilitate the concrete to move to the lower feeding assembly under the action of gravity.

[0065] Furthermore, an air relief valve is installed on the sealing cover plate 3, and the air pressure in the concrete cargo box 2 can be adjusted by opening and closing the air relief valve.

[0066] Further optimized solution, the pneumatic drive unit includes an air pump 12, the air pump 12 is fixedly connected in the seat box 4, the exhaust end of the air pump 12 is connected to each discharge port of the blanking assembly through a plurality of first connecting pipes 13, the first connecting pipes 13 correspond to the discharge ports of the blanking assembly one by one, and the middle of the first connecting pipe 13 is connected to a second solenoid valve 36, the second solenoid valve 36 is used to control the on-off of the first connecting pipe 13, and the opening and closing of the discharge port is controlled by controlling the on-off of the first connecting pipe 13;

[0067] A plurality of second solenoid valves 36 are electrically connected to the control unit;

[0068] The exhaust end of the air pump 12 is communicated with the intake end of the intake passage 14 .

[0069] A further optimized solution is that the unloading component includes a unloading bin 9, which is fixedly connected to the bottom of the vehicle body 1, and the top of the unloading bin 9 is connected to the middle of the bottom surface of the concrete cargo box 2. A rectangular shield 23 is fixedly connected to the top of the unloading bin 9, and a plurality of unloading pipes 24 arranged side by side are fixedly connected to the rectangular shield 23. The top end of the unloading pipe 24 is connected to the concrete cargo box 2, and the bottom end of the unloading pipe 24 is connected to an opening and closing part, and the opening and closing part is connected to the air outlet end of the corresponding first connecting pipe 13.

[0070] Further optimizing the scheme, the opening and closing part includes an outer wall tube 10, the outer wall tube 10 is fixedly connected to the inner wall of the lower material bin 9, and the bottom of the outer wall tube 10 passes through the bottom of the lower material bin 9;

[0071] The outer wall tube 10 is coaxially sleeved on the outer side of the corresponding feed tube 24;

[0072] An annular cover plate 22 is coaxially fixed to the top of the outer wall tube 10;

[0073] A vertical slide cylinder 19 is vertically slidable in the outer wall cylinder 10, and the vertical slide cylinder 19 is sleeved on the outer side of the feed pipe 24;

[0074] A closed communication chamber 28 is formed between the annular cover plate 22, the outer wall tube 10, the top of the vertical slide tube 19 and the feed tube 24. The communication chamber 28 is connected to the outside through an inlet and outlet pipe 27. The inlet and outlet pipe 27 is arranged in the side wall of the feed bin 9.

[0075] A closed air intake cavity 25 is formed between the outer wall cylinder 10 and the vertical slide cylinder 19. The air intake cavity 25 is connected to the corresponding first connecting pipe 13. The bottom of the air intake cavity 25 is connected to the outside through an exhaust pipe 34. The exhaust end of the exhaust pipe 34 is connected to a first solenoid valve 35.

[0076] The vertical slide cylinder 19 is limited and matched with the limited portion;

[0077] A plurality of discharge ports 20 are evenly spaced around the bottom side wall of the vertical slide 19 , and the discharge ports 20 are connected to a discharge pipe 24 . A baffle 21 for blocking the discharge end of the discharge pipe 24 is axially connected to the bottom of the vertical slide 19 .

[0078] In a further optimized solution, the limiting part includes a first retaining ring 26 and a second retaining ring 33, and the first retaining ring 26 and the second retaining ring 33 are coaxially fixed in the outer wall tube 10;

[0079] The first baffle ring 26 is located in the communication cavity 28 and below the connection point of the intake and exhaust pipes 27;

[0080] The second baffle ring 33 is located in the air inlet cavity 25 and above the air outlet end of the first connecting pipe 13 .

[0081] The discharge bin 9 is arranged at the bottom of the vehicle body 1 and is connected to the bottom of the concrete cargo box 2. A rectangular shield 23 is arranged on the top of the discharge bin 9. Several discharge pipes 24 are fixed side by side on the rectangular shield 23. Pumped concrete can enter each discharge pipe 24.

[0082] The outer wall tubes 10 whose number matches the discharge pipe 24 are fixedly connected in the discharge bin 9. The outer wall tubes 10 are correspondingly sleeved on the outside of the discharge pipe 24. A vertical slide tube 19 slides vertically in the outer wall tube 10. Under normal circumstances, the vertical slide tube 19 naturally comes out under the action of gravity, so that each discharge port 20 is exposed, and the baffle 21 no longer blocks the discharge end of the discharge pipe 24, so that concrete can be discharged through each discharge port 20. When it is necessary to prevent the concrete from being discharged, the second solenoid valve 36 on the corresponding first connecting pipe 13 is opened to enable the air pump 12 to transport air into the air inlet chamber 25. At this time, the first solenoid valve 35 on the corresponding exhaust pipe 34 is closed. With the air inlet chamber 2 5 increases, causing the vertical slide 19 to slide upward until it abuts against the bottom of the first baffle ring 26. At this time, the air in the connecting chamber 28 is discharged through the air inlet and exhaust pipes 27, and the baffle 21 blocks the discharge port of the discharge pipe 24 to prevent concrete from leaking out. When it is necessary to open the discharge port, the corresponding second solenoid valve 36 is closed, the first solenoid valve 35 is opened, and the corresponding first connecting pipe 13 no longer takes in air. The vertical slide 19 slides down under the action of gravity until it abuts against the top of the second baffle ring 33. The air inlet chamber 25 is exhausted through the exhaust pipe 34. After the vertical slide 19 slides down, each discharge port 20 leaks out, and the baffle 21 no longer blocks the discharge end of the discharge pipe 24, so that concrete can continue to leak out.

[0083] The first solenoid valve 35 is electrically connected to the control unit.

[0084] The control unit is preferably a PLC programmable controller, which is provided with a sophisticated visual recognition system, which can visually identify the manhole cover or the wellhead, and control the opening and closing of each first solenoid valve 35 and each second solenoid valve 36 according to the recognition data.

[0085] Further optimized solution, the vibrating rod 5 includes a vibrating tube wall 501, a rotating tube 504 is arranged inside the vibrating tube wall 501, the rotating tube 504 is a convex structure, one end of the rotating tube 504 is rotatably connected to the inner wall of the vibrating tube wall 501, the other end of the rotating tube 504 is rotatably connected to a connecting block 503, the air inlet end of the rotating tube 504 is connected to the air outlet end of the connecting block 503, and the air inlet end of the connecting block 503 is connected to the air outlet end of the connecting hose 17 through the air inlet pipeline 502;

[0086] A plurality of exhaust holes 505 are evenly spaced in the middle of the rotating tube 504, and the exhaust holes 505 are connected to an air cavity 507, which is arranged in the vibrating tube wall 501 and is connected to the exhaust hose 29;

[0087] A collision portion is fixedly connected to the middle of the rotating tube 504 .

[0088] According to a further optimized solution, the collision part includes a plurality of collision pieces 506 . The collision pieces 506 are arranged between two exhaust holes 505 . The collision pieces 506 are arranged in contact with the inner wall of the vibrating tube wall 501 .

[0089] When in use, the gas pumped out by the air pump 12 enters the rotating tube 504 through the air intake channel 14, the second connecting pipe 15, the exhaust channel 16, the connecting hose 17 and the air intake pipeline 502 in sequence, and discharges the gas into the air cavity 507 through each exhaust hole 505. The exhaust through each exhaust hole 505 causes the rotating tube 504 to rotate, and each striker 506 collides with the inner wall of the vibrating tube wall 501 during the rotation of the rotating tube 504. At the same time, due to the eccentric movement of each striker 506 in the vibrating tube wall 501, the vibrating tube wall 501 is vibrated under the action of centrifugal force, thereby achieving the effect of vibrating concrete. The gas in the air cavity 507 is discharged into the concrete cargo box 2 through the exhaust hose 29, so as to form air pressure on the upper part of the concrete cargo box 2 to push the concrete to move toward each discharge pipe 24.

[0090] The vibrating pipe wall 501 is suspended at the bottom of the vehicle body 1 through the connecting hose 17 and the exhaust hose 29, and can naturally sink into the concrete under the action of gravity. When encountering a wellhead or the like, it can move along the contour of the side wall of the wellhead, so that the part of the vibrating pipe wall 501 passing through the wellhead area can be naturally lifted, while the other part is still sunk into the concrete for vibration.

[0091] A further optimized solution is that the scraping assembly includes a scraper 6, one end of the scraper 6 is hinged to the tail end of the concrete cargo box 2 in the traveling direction, and one end of an elastic telescopic rod 7 is hinged to the front and rear sides of the scraper 6 respectively, and the other end of the elastic telescopic rod 7 is hinged to the side wall of the concrete cargo box 2.

[0092] The scraper 6 can adjust the angle through the elastic telescopic rod 7 so that the bottom end of the scraper 6 can scrape the concrete surface flat. When passing through the wellhead area, if the top of the wellhead protrudes from the road surface, the scraper 6 can be pushed up, and then the initial angle is restored under the action of the elastic telescopic rod 7 to continue scraping.

[0093] According to a further optimized solution, a plurality of ventilation holes 11 are provided on the seat box 4 .

[0094] The air pump 12 is arranged in the seat box 4, and its air inlet end introduces external air through a plurality of ventilation holes 11.
