Description

Technical Field

[0001] The present invention relates to the field of intelligent construction technology, and in particular to intelligent construction equipment for municipal facilities. Background Art

[0002] Smart construction refers to the optimized combination based on construction needs, thereby providing an efficient and convenient construction environment. The construction of pavement roads has always been an important foundation in the construction of municipal facilities. Pavement construction generally involves pouring concrete on the ground and then spreading it to make the concrete uniform and the road surface smooth.

[0003] In the existing technology, concrete is generally output by pouring it onto the ground by a concrete truck, and then flattening it with equipment such as a road roller. This method is not convenient for directly paving a road surface of a predetermined width. The edges need to be repaired after flattening to make the road surface edges neat.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention is provided with an adjusting mechanism and a limiting mechanism. The adjusting mechanism is used to adjust the unloading width of the unloading box. Pre-adjusting the concrete unloading width can reduce concrete waste and also reduce the trimming operation after unloading. The width of the bottom opening of the unloading box is reduced by gradually closing the grooves by the opposite oblique sides of the two triangular baffles, thereby realizing the reduction of the concrete unloading width. Since the side walls of the folding block can fold and flatten both sides of the concrete during paving, it is convenient to control the width of the paved road surface and reduce secondary processing after roller flattening. Therefore, as the adjusting mechanism reduces the paving width, the two folding blocks approach each other to reduce the folding width. When the paving width is increased, the two folding blocks move away from each other to increase the folding width. The limiting mechanism can cooperate with the adjusting mechanism to synchronously adjust the folding width of the two folding blocks, so that the folding width of the folding blocks is always consistent with the unloading width, thereby ensuring that both sides of the unloaded concrete are effectively folded during paving construction, facilitating subsequent flattening, reducing concrete waste, and improving the convenience of municipal construction.

[0020] The present invention sets a quantitative mechanism, which is used in conjunction with the retracting block and the annular turntable. Since the paving speed is required to be uniform when paving concrete to build a road, there are strict requirements on the road length, and equidistant lines need to be drawn on the center and both sides of the road surface later. Therefore, when the second motor drives the annular turntable to rotate at a uniform speed, the rollers on both sides of the annular turntable can push the two quantitative sliders to slide along the second slide groove at a uniform speed, so that the circular holes of the quantitative sliders can be connected to the discharge outlet at a uniform speed and periodically, thereby realizing the periodic release of the colored paint in the storage box. Since the discharge outlet is connected to the through hole and the discharge nozzle, the retracting The blocks are always kept on both sides of the concrete by the drive of the limiting mechanism. At this time, the colored paint can be released periodically and uniformly on both sides of the concrete through the feeding nozzle, that is, equidistant lines are drawn synchronously during the paving operation, which has a positive effect on the control of construction progress and the measurement of road length. The drawn equidistant lines can also be used to beautify the road surface after the road surface is solidified, such as providing a distance reference when drawing road markings. At the same time, the drawn equidistant lines are equivalent to the width of the road. If the two sides of the road are damaged by external influences during the construction process, they can also be repaired more effectively according to the position of the equidistant lines, thereby improving the quality of road construction.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Reference Figure 1-13, an intelligent construction equipment for municipal facilities, including a frame 1 and a folding block 19, the frame 1 is a symmetrical structure, with bottom baffles 102 fixedly connected on both sides of the bottom end of the frame 1, a first connecting column 7 is fixedly installed on one side of the top of the frame 1, and a second connecting column 8 is fixedly installed on the other side of the top of the frame 1, the top and bottom of the first connecting column 7 and the second connecting column 8 are fixedly connected to a mounting plate 9, an adjustment mechanism 10 including an electric telescopic rod 11 and a triangular baffle 13 is provided between the two mounting plates 9, two first slide grooves 15 are symmetrically opened at the bottom of the first connecting column 7, a slider 17 is slidably connected in the first slide groove 15, a connecting rod 18 is fixedly connected to the bottom end of the slider 17, and a folding block 19 is fixedly connected to the bottom end of the connecting rod 18, a limiting mechanism 14 including a gear 16 is provided at both ends of the first slide groove 15, and two symmetrical fixed boxes 26 are fixedly connected on both sides of the bottom end of the bottom mounting plate 9, and a quantitative mechanism 27 including a second slide groove 28 and a quantitative slider 30 is provided in the fixed box 26;

[0037] Four electric telescopic rods 11 are fixedly installed between the second connecting column 8 and the opposite surface of the first connecting column 7. The telescopic ends 12 of the electric telescopic rods 11 pass through the first connecting column 7. A triangular baffle 13 is fixedly connected to the ends of every two adjacent telescopic ends 12. The two triangular baffles 13 are symmetrical to each other, and a rack is provided at the bottom of each telescopic end 12.

[0038] A circular groove 151 is formed inside the first connecting column 7 at both ends of the first chute 15. A gear 16 is rotatably connected in the circular groove 151. Each gear 16 is respectively engaged with each rack. A first screw 161 threadedly connected to the slider 17 is fixedly connected to the center of the opposite surface of the gear 16 at both ends of each first chute 15.

[0039] A second chute 28 is provided on one side of the fixed box 26, and a discharge outlet 29 is provided at the bottom end of the second chute 28. A quantitative slider 30 is slidably connected in the second chute 28, and a circular hole of the same size as the discharge outlet 29 is provided on one side of the quantitative slider 30. The frame 1 is formed into a whole by the connection of the first connecting column 7 and the second connecting column 8. The bottom baffle 102 is an extension of the bottom of the frame 1. It can be used as a carrier for the mixing screw 6 and the roller 33, and can also block the concrete when the concrete is discharged to prevent concrete splashing. Combined with the retraction effect of the retraction block 19, it can greatly reduce the time of the secondary processing in the later stage, which has a positive effect on improving the efficiency of municipal construction. The adjustment mechanism 10 is used to adjust the discharge width of the discharge box 2. For some road surfaces with different construction requirements, the road surface width is also different. Pre-adjusting the concrete discharge width can reduce concrete waste and reduce the trimming operation after discharge. By controlling the electric telescopic The rod 11 is extended to push the two triangular baffles 13 to slide toward the slot 301, so that the opposite oblique sides of the two triangular baffles 13 gradually close the slot 301 to reduce the width of the bottom opening of the discharge box 2, thereby reducing the width of the concrete discharge. Since the side walls of the stop block 19 can be retracted and scraped flat on both sides of the concrete during paving, it is convenient to control the width of the paved road surface and reduce secondary processing after the roller 33 is flattened. Therefore, as the adjustment mechanism 10 reduces the paving width, when the telescopic end 12 of the electric telescopic rod 11 is extended, the rack at the bottom end of the telescopic end 12 can push the gear 16 to rotate, and the two gears 16 at both ends of the same first slide 15 rotate synchronously to drive the first screw The rod 161 rotates so that the slider 17 can slide along the first slide groove 15. When the telescopic end 12 is extended, the two sliders 17 approach each other. When the telescopic end 12 is retracted, the two sliders 17 move away from each other, that is, when the paving width is reduced, the two retraction blocks 19 move closer to each other to reduce the retraction width. When the paving width is increased, the two retraction blocks 19 move away from each other to increase the retraction width. The limiting mechanism 14 can cooperate with the adjusting mechanism 10 to synchronously adjust the retraction width of the two retraction blocks 19, so that the retraction width of the retraction blocks 19 is always consistent with the blanking width, which can ensure that both sides of the blanking concrete are effectively retracted during paving construction, facilitate subsequent flattening, and reduce concrete waste. The quantitative mechanism 27 is used in conjunction with the retracting block 19 and the annular turntable 21 at the same time. Since the paving speed is required to be uniform when paving concrete to build a road, there are strict requirements on the road length, and equidistant lines need to be drawn in the center and both sides of the road surface later. Therefore, when the second motor 20 drives the annular turntable 21 to rotate at a uniform speed, the rollers 23 on both sides of the annular turntable 21 can push the two quantitative sliders 30 to slide along the second chute 28 at a uniform speed, so that the circular holes of the quantitative sliders 30 can be connected to the discharge outlet 29 at a uniform speed and periodically, thereby realizing the periodic release of the colored paint in the storage box 24. Since the discharge outlet 29 is connected to the through hole 191 and the discharge nozzle 192,The retracted stopper 19 is always kept on both sides of the concrete by the limit mechanism 14. At this time, the colored paint can be released periodically and uniformly on both sides of the concrete through the discharge nozzle 192. That is, equidistant lines are drawn synchronously during the paving operation, which has a positive effect on the control of construction progress and the measurement of road length. In addition, the drawn equidistant lines can also be used for beautification operations of the road after the road surface solidifies, such as providing a distance reference when drawing road surface markings. At the same time, the drawn equidistant lines are equivalent to the width of the road. If the two sides of the road are damaged by external influences during the construction process, they can also be repaired more effectively based on the position of the equidistant lines, thereby improving the quality of road construction.

[0040] As a technical optimization solution of the present invention, four track wheels 101 are symmetrically arranged at both ends of the vehicle frame 1. Each track wheel 101 is equipped with a drive motor at the connection point with the vehicle frame 1. During concrete paving, the drive motor drives the four track wheels 101 to propel the vehicle frame 1 as a whole, pouring concrete onto the road surface along the paving route, performing the following operations: unloading, mixing, gathering, evenly spreading, and flattening.

[0041] As a technical optimization solution of the present invention, a material discharge box 2 is fixedly mounted on the top of one end of the vehicle frame 1. Two material discharge baffles 3 are symmetrically mounted on either side of the bottom outlet of the material discharge box 2. Slots 301 are symmetrically defined at both ends of the two material discharge baffles 3. The thickness of the triangular baffles 13 is the same as the height of the slots 301. The two triangular baffles 13 are slidably connected to the two sets of slots 301. The material discharge box 2 also has slots corresponding to the slots 301 to facilitate the movement of the triangular baffles 13.

[0042] As a technical optimization solution of the present invention, a fixing plate 4 is fixedly installed on one side of the top of the frame 1 close to the triangular baffle 13, and a first motor 5 is fixedly installed on both ends of the top of the fixing plate 4. The bottom baffle 102 below the first motor 5 is rotatably connected to a mixing screw 6 that is centrally symmetrical in the spiral direction. The end of the rotating shaft of the mixing screw 6 passes through the bottom baffle 102, and the end of the rotating shaft of the mixing screw 6 is fixedly connected to a synchronous wheel 52. The output end of the first motor 5 is connected to the synchronous wheel 52 through the output wheel and the synchronous belt 51. During paving construction, the first motor 5 is started, and the two first motors 5 drive the output wheels to rotate. The synchronous belt 51 and the synchronous wheel 52 rotate synchronously to drive the mixing screw 6 to rotate. In order to reduce the deviation of the concrete along the two sides of the road, the mixing screw 6 is set to a symmetrical structure, that is, when the mixing screw 6 is working, the concrete tends to deviate to the middle of the road. However, since the mixing screw 6 is in an open environment, the deviation of the concrete to the middle is very small, which has no effect on the overall uniformity of the road, but can reduce the deviation on both sides, which plays a positive role in limiting the width of the paved road surface. In conjunction with the retracting block 19, the paving width can be effectively controlled.

[0043] As a technical optimization solution of the present invention, a through hole 191 is formed in the top of the retracting block 19, and a discharge nozzle 192 is installed on the bottom side wall of the retracting block 19. The through hole 191 and the discharge nozzle 192 are connected. The through hole 191 on the same side is connected to the discharge outlet 29 through a discharge hose 251. The through hole 191 and the discharge nozzle 192 are connected by a connecting groove inside the retracting block 19. While retracting the two sides of the concrete, the retracting block 19 can evenly release the colored paint through the discharge nozzle 192, thereby drawing equidistant lines. The discharge hose 251 is stretchable and can extend or contract with the movement of the retracting block 19.

[0044] As a technical optimization solution of the present invention, a second motor 20 is fixedly mounted at the top center of the mounting plate 9. The output shaft 201 of the second motor 20 vertically extends through the bottom mounting plate 9. The bottom end of the output shaft 201 is fixedly connected to the annular turntable 21. A number of vertically mounted shifting levers 22 are evenly arranged at the bottom end of the annular turntable 21. The rotation of the second motor 20 drives the output shaft 201 to rotate, causing the annular turntable 21 to rotate synchronously, thereby driving the shifting levers 22 to rotate. The shifting levers 22 can stir the concrete, making the concrete more uniform and improving the flattening effect of the roller 33. Due to the effect of the mixing screw 6 on the concrete to tend to deviate toward the middle of the road, the annular turntable 21 and the shifting levers 22 can also effectively prevent the problem of excessive concrete in the middle of the road, thus preventing problems before they occur.

[0045] As a technical optimization solution of the present invention, two rollers 23 are rotatably mounted on the radial sidewall of the annular turntable 21. The rollers 23 and the quantitative slider 30 are on the same horizontal line. The side of the quantitative slider 30 close to the annular turntable 21 is an arc-shaped structure. The sidewall of the quantitative slider 30 away from the annular turntable 21 is fixedly connected to a guide sleeve 31. The guide sleeve 31 is slidably connected to the guide rod on the sidewall of the second chute 28. The outer wall of the guide sleeve 31 is sleeved with a spring 32. The rotation of the annular turntable 21 causes the two rollers 23 to periodically push the two quantitative sliders 30 to slide along the second chute 28. At this time, the spring 32 is compressed, and the guide sleeve 31 facilitates guidance to prevent the spring 32 from deflecting. When the roller 23 is separated from the quantitative slider 30, the spring 32 loses its force and resets, pushing the quantitative slider 30 to reset, thereby realizing the periodic connection between the discharge outlet 29 and the storage box 24, thereby releasing the colored paint.

[0046] As a technical optimization solution of the present invention, a storage box 24 is fixedly mounted between the two mounting plates 9 above the fixed box 26. A feeding port 241 is provided at the top of the storage box 24, and a discharge pipe 25 is connected to the bottom of the storage box 24. The two discharge pipes 25 are respectively connected to the two second chutes 28, and the discharge pipes 25 correspond to the discharge outlet 29. The storage box 24 contains colored paint for drawing equidistant lines. The feeding port 241 is used to add colored paint. The colored paint flows through the discharge pipe 25 into the discharge outlet 29 and finally flows into the discharge nozzle 192 through the discharge hose 251.

[0047] As a technical optimization solution of the present invention, the centers of both ends of the second connecting column 8 are rotatably connected to rollers 33 through rotating arms, and a fixed rod 34 is fixedly connected between the rotating arms. The center of the fixed rod 34 is fixedly connected to a rotating block 35 rotatably connected to the center of the second connecting column 8. The center of the bottom end of the second connecting column 8 is rotatably connected to an electric cylinder 36, and the telescopic end of the electric cylinder 36 is rotatably connected to the bottom of the rotating block 35. The centers of the side walls of both ends of the roller 33 are fixedly connected to limiting screws 37, and an arc-shaped slide groove is opened on the top of one side of the bottom baffle 102. The limiting screw 37 is slidably connected to the arc-shaped slide groove, and the end of the limiting screw 37 is threadedly connected to a limiting nut 371. The roller 33 is used to flatten the concrete that has been spread on the ground after mixing and gathering. In actual use, the extension and contraction of the electric cylinder 36 can be controlled according to the required paving height to drive the rotating block 35, the fixing rod 34 and the roller 33 to rotate around the center of the second connecting column 8. The height from the bottom end of the roller 33 to the ground can be adjusted by rotation, and then the flattening height can be adjusted in accordance with the thickness of the released concrete. When the roller 33 is adjusted, the limiting screw 37 slides along the arc-shaped slide groove. When the roller 33 is adjusted into place, the electric cylinder 36 is stopped and the limiting nut 371 is tightened with a wrench to fix the position of the roller 33 to prevent the electric cylinder 36 from being subjected to excessive force and losing control during the pressing operation, causing the height of the roller 33 to be out of control.

[0048] When the present invention is in use, the unloading width is first adjusted according to the paving requirements of the road surface, and the telescopic end 12 of the electric telescopic rod 11 is controlled to extend to push the two triangular baffles 13 to slide toward the slot 301, so that the opposite oblique sides of the two triangular baffles 13 gradually close the slot 301 to reduce the width of the bottom opening of the unloading box 2, and vice versa. At the same time, the rack at the bottom end of the telescopic end 12 can push the gear 16 to rotate, and the two gears 16 at both ends of the same first slide 15 can rotate synchronously to drive the first screw 161 to rotate, so that the slider 17 can slide along the first slide 15. When the telescopic end 12 is extended, the two sliders 17 approach each other, and when the telescopic end 12 is retracted, the two sliders 17 move away from each other, that is, when the paving width is reduced, the two retracted sliders 17 move away from each other. The closing blocks 19 move closer to each other to reduce the closing width. When the paving width is increased, the two closing blocks 19 move away from each other to increase the closing width. After the unloading width is adjusted, the electric telescopic rod 11 is stopped, and then the extension and contraction of the electric cylinder 36 is controlled according to the required paving height to drive the rotating block 35, the fixed rod 34 and the roller 33 to rotate around the center of the second connecting column 8. The height from the bottom end of the roller 33 to the ground is adjusted by rotation, and then the flattening height can be adjusted in accordance with the released thickness of the concrete. When the roller 33 is adjusted, the limiting screw 37 slides along the arc-shaped slide groove. When the roller 33 is adjusted into place, the electric cylinder 36 is stopped, and the limiting nut 371 is tightened with a wrench to fix the position of the roller 33. Then, colored paint is added to the two storage boxes 24 through the feeding port 241. At this time, the preparation work is completed.

[0049] Start the four track wheels 101 to drive the frame 1 to move, and the concrete truck in front of the frame 1 pours concrete into the lower material box 2. The concrete is discharged through the adjusted discharge baffle 3 and spread on the ground. Start the first motor 5, and the two first motors 5 drive the output wheel to rotate. The synchronous belt 51 and the synchronous wheel 52 rotate synchronously to drive the mixing screw 6 to rotate, and the concrete is mixed and pushed away. The opposite surfaces of the two retraction blocks 19 retract the two sides of the concrete to make the two sides flush. The bottom baffle 102 can prevent concrete from splashing. At the same time, start the second motor 20. The rotation of the second motor 20 drives the output shaft 201 to rotate, so that the annular turntable 21 rotates synchronously, which can drive the lever 22 to rotate, and the lever 22 can be adjusted. As the concrete is stirred, the annular turntable 21 rotates, causing the two rollers 23 to periodically push the two quantitative sliders 30 to slide along the second slide groove 28. At this time, the spring 32 is compressed. When the roller 23 disengages from the quantitative slider 30, the spring 32 loses force and resets, pushing the quantitative slider 30 to reset, thereby realizing the periodic connection between the discharge outlet 29 and the storage box 24. The colored paint can flow into the discharge outlet 29 through the discharge pipe 25 and finally flow into the discharge nozzle 192 through the discharge hose 251. At this time, the colored paint can be released periodically at a uniform speed on both sides of the concrete through the discharge nozzle 192, that is, equidistant lines are drawn synchronously during the paving operation. Finally, the concrete is flattened by the roller 33 and can be waited for solidification.
