[0002] The concrete pavement construction process covers the entire process from preliminary preparation to final formation, including preliminary site cleaning and surveying and setting out, construction of base and subbase, installation of formwork, concrete paving, vibration and leveling, and later pavement joint treatment and maintenance, and finally quality inspection and demolding.

[0003] In the process of paving, vibrating and leveling concrete, a concrete construction pavement casting device is needed. The existing concrete construction pavement casting device is designed based on a horizontal pavement, but in the construction process in mountainous areas, it is often necessary to construct an inclined pavement. Since concrete is fluid during construction, it will flow downward along the roadbed, resulting in the concrete pavement being thinner at the upper end and thicker at the bottom end. During solidification, excessive local stress is generated, which affects the service life of the pavement.

[0027] The vibrating feeding mechanism 6 also includes a mounting ring 6051 and a gear block 6053. The mounting ring 6051 is fixedly connected to the feeding tube 605 in a sleeve manner.

One end of the fifth connecting rod 606 is rotatably connected to a crankshaft 607. Two adjacent crankshafts 607 face opposite directions. A second sliding rod 608 is fixedly connected to one side of the crankshaft 607, and a third sliding rod 609 is fixedly connected to the other side. The second sliding rod 608 is slidably connected to the third sliding rod 609. The two second sliding rods 608 located on the front and rear sides are respectively rotatably connected to the two first support frames 1, and the second sliding rod 608 located on the rear side is connected to the second driven pulley of the second belt transmission assembly 504.

[0029] It also includes a rolling flattening component 7 and a residual material scraping component 8. A second support frame 102 is fixedly connected to the left side of the first support frame 1. A gear set 103 is installed on the second support frame 102. The gear set 103 includes a meshing driving gear and a driven gear. A rolling flattening component 7 and a residual material scraping component 8 are installed between the two first support frames 1. The rolling flattening component 7 includes a friction roller 701. A friction roller 701 is rotatably connected to one side of the first support frame 1. One end of the friction roller 701 is connected to the driving gear of the gear set 103. A plurality of rolling rods 702 are linearly distributed between the two friction rollers 701. Two adjacent rolling rods 702 are connected by threads, and the rolling rods 702 located on the front and rear sides are respectively threadedly connected to the two friction rollers 701.

[0030] The residual material scraping assembly 8 includes an auger sleeve 801 , one side of the first support frame 1 is rotatably connected with the auger sleeve 801 , one end of the auger sleeve 801 is connected to the driven gear of the gear set 103 , and the two auger sleeves 801 are commonly threadedly connected with a bidirectional auger 802 .

[0031] In the initial state, the first friction column 203 and the second friction column 206 remain separated, and the rolling rod 702 is not installed on the friction roller 701. The staff first installs a number of casting templates 9 in the construction area, and moves the first support frame 1 according to the distance between the casting templates 9 on both sides to adjust the distance between the two first support frames 1. In the process of adjusting the distance between the two first support frames 1, the third hinge column 6022 slides in the linear slide groove of the first support frame 1, so that the third hinge column 6022 drives the third connecting rod 601 to move synchronously, and the two adjacent third connecting rods 601 are squeezed and rotated by the first hinge column 602 and the second hinge column 6021. If the two first support frames 1 move away from each other, the first support frames 1 will move away from each other. The two third hinged columns 6022 sliding on the support frame 1 are close to each other, so that the first hinged columns 602 are separated from each other, and the second hinged columns 6021 of the same group are close to each other. The first hinged columns 602 and the second hinged columns 6021 move together to separate the cross bars 603. If the two first support frames 1 are close to each other, the two third hinged columns 6022 sliding on the first support frame 1 are separated from each other, so that the first hinged columns 602 are close to each other, and the second hinged columns 6021 are separated from each other in the left and right directions. The first hinged columns 602 and the second hinged columns 6021 move together to separate the cross bars 603. The cross bars 603 are close to each other through the second hinged columns 602. The sliding frame 604 drives the feeding tube 605 to move synchronously, so that the feeding tube 605 can adapt to the casting templates 9 at different distances. The movement of the second sliding frame 604 will also drive the gear blocks 6053 on the front and rear sides to move synchronously through the third spring. The gear blocks 6053 drive the vibration rod 6054 to move synchronously, so that the vibration rod 6054 can adapt to the casting templates 9 at different distances. The movement of the feeding tube 605 drives the rack 6052 to move synchronously through the mounting ring 6051. At the same time, the feeding tube 605 drives the crankshaft 607 to move synchronously through the fifth connecting rod 606, so that the third sliding rod 609 slides in the second sliding rod 608, so that the crankshaft 607 can adapt to the feeding tubes 605 at different positions. At the same time, the first supporting frame 1 moves away from each other so that The auger sleeve 801 drives the two-way auger 802 to rotate through the threaded groove, so that the distance between the two auger sleeves 801 becomes longer, thereby lengthening the entire excess material scraping assembly 8, so that the excess material scraping assembly 8 can adapt to casting templates 9 at different distances. The staff connects several rolling rods 702 through threads to realize that the rolling flattening assembly 7 can adapt to casting templates 9 at different distances. After several rolling rods 702 are connected, the length of the rolling flattening assembly 7 is fixed, so that the distance between the two second support frames 102 is fixed, and then the distance between the two first support frames 1 is fixed. At this time, the vibrating unloading mechanism 6, the rolling flattening assembly 7 and the excess material scraping assembly 8 can adapt to casting templates 9 at different distances, which is convenient for casting concrete pavements of different widths.

[0032] The staff places the device on the casting template 9, so that the bottom of the first roller 212 and the friction roller 701 are in contact with the top of the casting template 9. The second spring contracts to drive the C-shaped frame 303 to move through the first sliding frame 302, so that the C-shaped frame 303 drives the second roller 304 to contact and squeeze the casting template 9, so that the second roller 304 can roll on the casting template 9, completing the placement of the device.

[0033] After placing the device, the staff needs to start the device first to improve the pouring effect of concrete, and start the first motor 202. The output shaft of the first motor 202 rotates clockwise to drive the first friction column 203 to rotate. Since the first friction column 203 is disengaged from the second friction column 206, the first friction column 203 idles; at the same time, the staff starts the second motor 503. The output shaft of the second motor 503 rotates to drive the one-way auger 502 to rotate. The one-way auger 502 rotates through the second belt transmission assembly 504 to drive the second sliding rod 608 to rotate. The second sliding rod 608 drives the crankshaft 607 to rotate synchronously through the third sliding rod 609. The crankshaft 607 rotates through the fifth connecting rod 606 to drive the discharge pipe 605 to slide back and forth in the second sliding frame 604. The discharge pipe 605 reciprocates The motion can stir the concrete, thereby removing the bubbles in the concrete. At the same time, the feed tube 605 reciprocates and slides through the mounting ring 6051 to drive the rack 6052 to move synchronously, so that the rack 6052 pushes the tooth block 6053 to move toward the left and right sides through its own teeth during the movement, so that the tooth block 6053 is disengaged from the tooth groove of the rack 6052, and the third spring is stretched by force. When the teeth of the rack 6052 pass over the tooth block 6053 it pushes, the third spring contracts, so that the tooth block 6053 is stuck in another tooth groove of the rack 6052 and collides with the tooth groove to generate vibration. The vibration will be transmitted from the tooth block 6053 to the vibration rod 6054, and then transmitted from the vibration rod 6054 to the concrete, thereby removing the bubbles in the concrete. At this time, the device start-up before concrete pouring is completed.

[0034] After the first motor 202 and the second motor 503 are started, the staff pours the prepared concrete into the trough 501. The concrete is stirred by the rotating one-way auger 502 in the trough 501 to avoid the concrete from settling and keep the concrete in a uniform state, thereby improving the quality of concrete pouring. At the same time, the concrete enters the discharge pipe 605 through the hose and flows out from the discharge pipe 605, so that the concrete is injected into and fills the casting templates 9 on both sides. Since the concrete itself has a large viscosity, the accumulated concrete pile is approximately in the shape of a cone. As the concrete continues to flow out of the discharge pipe 605, the concrete liquid level gradually increases, and the concrete gradually submerges the discharge pipe 605 and the vibration rod 6054, so that the discharge pipe 6 The reciprocating motion of 05 and the vibration of the vibration rod 6054 drive the bubbles in the surrounding concrete to vibrate, so that the bubbles in the concrete float upward and detach from the concrete under the buoyancy of the concrete, thereby eliminating the bubbles in the concrete, improving the mechanical strength of the concrete pouring, and further improving the service life of the concrete at the pouring location. When the concrete contacts the buoyancy ball 210, the buoyancy ball 210 moves upward, and controls the first connecting rod 208 to move upward through the second connecting rod 209, so that the first connecting rod 208 moves to drive the sliding block 207 to squeeze the second friction column 206. It is worth noting that if there is an angular deviation between the device and the horizontal plane, that is, the concrete pavement to be poured is an inclined pavement, then under the gravity and the damping between the first connecting rod 208 and the second connecting rod 209, the sliding block 207 is pressed against the second friction column 206. , the two buoyancy balls 210 will respectively drive the two second connecting rods 209 to rotate slowly until the second connecting rod 209 returns to verticality. If the second connecting rod 209 rotates clockwise, the buoyancy ball 210 on the left side is closer to the concrete. If the second connecting rod 209 rotates counterclockwise, the buoyancy ball 210 on the right side is closer to the concrete. At this time, the driving force for the sliding block 207 to rise is provided by the buoyancy ball 210 closest to the concrete. Since concrete has fluidity, when pouring an inclined road surface, a small amount of concrete will flow downward along the inclined surface. Since the first connecting rod 208 is inclined, when the second connecting rod 209 returns to verticality, the height of the buoyancy ball 210 closest to the concrete will be lower, thereby reducing the thickness judgment of the inclined concrete road surface when pouring. The flow reserves flow space to ensure the uniform thickness of the concrete pavement, so that the thickness of the buoyancy ball 210 is adapted to the inclination angle of the concrete pavement, and the thickness detection of the concrete pavement with different inclination angles is realized. Since the second connecting rod 209 rotates slowly, the thickness judgment of the inclined concrete pavement during pouring changes slowly, that is, the inclined concrete pavement is thicker at the bottom and thinner at the top during pouring. It is worth noting that the difference in thickness of the concrete pavement caused by the flow of concrete is due to the fact that the flow of concrete will cause the inside of the concrete to be squeezed and bulge outward, and the bulging concrete can use its own viscosity to make more concrete flow. Compared with the difference in thickness of the concrete pavement caused by the flow of concrete, the contour of the poured inclined concrete pavement is approximately a natural logarithmic curve.The inclined concrete pavement below is made to have a smaller inclination angle, and the inclined concrete pavement below has a better supporting effect on the inclined concrete pavement above, thereby reducing the convexity of the inclined concrete pavement when it flows, and utilizing the viscosity of the concrete itself to suppress the convex concrete and drive more concrete to flow, so that the inclined concrete pavement has a stronger shear resistance, and the flow of concrete is suppressed. There is an essential difference between the two; the second friction column 206 is squeezed and moves toward the first friction column 203, and at the same time the first spring is stretched, and the second friction column 206 moves to contact with the first friction column 203 and squeeze each other, so that the first friction column 203 drives the second friction column 206 to rotate, and at this time the second friction column 206 drives the first spring and the rotating shaft 205 to rotate synchronously, so that the rotating shaft 205 drives the first roller 212 to rotate through the first belt transmission assembly 211 The first roller 212 is moved clockwise to control the whole device to move rightward along the casting template 9. When the concrete cannot provide enough buoyancy, the buoyancy ball 210 moves downward, and the first link 208 is controlled to move downward by the second link 209, so that the first link 208 moves to drive the sliding block 207 to release the second friction column 206. The first spring contracts to make the second friction column 206 move away from the first friction column 203, and the second friction column 206 no longer rotates, so that the second friction column 206 drives the rotating shaft 205 to stop synchronously, and the rotating shaft 205 keeps the first roller 212 stationary through the first belt transmission assembly 211, so that the device stops moving. Through the above actions, the concrete is evenly filled between the casting templates 9 on both sides, reducing the casting defects of the concrete and improving the casting efficiency of the concrete, and completing the casting of the concrete pavement.

[0035] During the further movement of the device, if the device needs to rotate left and right along the casting templates 9 on both sides, the side walls of the casting templates 9 will squeeze the two second rollers 304, so that the two second rollers 304 drive the C-shaped frame 303 to rotate on the first sliding frame 302, and at the same time, the C-shaped frame 303 drives the first sliding frame 302 to move so that the second spring stretches or contracts. During the rotation of the C-shaped frame 303, the plane where the axes of the two second rollers 304 are located always remains parallel to the casting template 9, so that the two second rollers 304 guide the C-shaped frame 303, so that the C-shaped frame 303 drives the device to always keep moving on the casting template 9 without deviation, thereby ensuring the stability of the device during movement.

[0036] When the device moves to the right, the friction roller 701 rolls on the top of the casting template 9, and the rolling of the friction roller 701 drives the rolling rod 702 to rotate synchronously. At the same time, the rolling of the friction roller 701 drives the auger sleeve 801 to rotate counterclockwise through the gear set 103. The rotation of the auger sleeve 801 drives the two-way auger 802 to rotate synchronously. The auger sleeve 801 and the two-way auger 802 rotate to make their own spiral protrusions scrape on the top of the concrete, so that the residual concrete is scraped to the center of the two-way auger 802. In the process of scraping, the residual concrete will be filled into the gap defects of the concrete pile to enhance the mechanical strength of the concrete pavement during molding. Thereby, the auger sleeve 801 and the two-way auger 802 can recycle the residual material on the top of the poured concrete pile. The residual concrete after filling the gap defects will be pushed by the auger sleeve 801 and the two-way auger 802 to move synchronously, so as to prevent the residual concrete from affecting the subsequent operations. The concrete pavement with the residual material scraped off will be squeezed by the rolling rod 702 rolling to the right, so that the scratches on the concrete pavement are squeezed out and the concrete pavement is smoothed. At the same time, the concrete is squeezed by the rolling rod 702, which makes the internal structure more compact and the mechanical structure more stable, so as to avoid cracking of the concrete pavement when it solidifies and realize the flattening and strength enhancement of the concrete pavement.
