Description

Technical Field

[0001] The present application relates to the field of paver technology, and in particular to a concrete pavement paver suitable for continuous construction. Background Art

[0002] With the rapid development of my country's economy, the construction of my country's infrastructure has also developed rapidly, especially the construction of road facilities. In the process of concrete pavement construction, concrete pavers are usually used. Concrete pavers are construction machines that spread the mixed cement concrete along the given thickness, width and road type requirements of the roadbed, and then perform operations such as vibration, leveling and smoothing to complete the paving of concrete pavement.

[0003] At present, during the construction of existing concrete pavement, concrete formwork is first set up on both sides of the road, and then the concrete is dumped near the center of the road by a concrete transport truck, and then the concrete is spread using a concrete paver. During the spreading process, since the concrete is accumulated in the center of the road, the construction workers are required to scrape the accumulated concrete to the positions on both sides of the road where there is less concrete for preliminary leveling.

[0004] With respect to the above-mentioned related technologies, the inventors found that during the paving process, the paver needs to wait for the construction workers to preliminarily flatten the concrete in front before paving, which results in a low paving efficiency during the paving of the concrete pavement. Summary of the invention

[0005] In order to solve the problem of low paving efficiency during paving of concrete pavement, the present application provides a concrete pavement paver suitable for continuous construction.

[0006] The present application provides a concrete pavement paver suitable for continuous construction, which adopts the following technical solution:

When paving concrete, the leveling device is used to preliminarily level the concrete accumulated on the road, and then the paving device is used to pave it, thereby reducing the possibility of manual preliminary leveling, thereby reducing the possibility of the paver waiting for the construction personnel to preliminarily level the concrete before paving, thereby realizing the continuous construction of the paver and improving the paving efficiency of the paver.

[0010] By adopting the above technical solution, the push plate is set as a "V"-shaped plate, and the "V"-shaped setting of the push plate is used to divert the concrete accumulated in front of the push plate to both sides of the road. At the same time, the first spiral blade set in front of the two inclined parts is used to transport the concrete accumulated in front of the push plate to both sides, thereby achieving preliminary leveling of the concrete, reducing the possibility of manual leveling of the concrete, and reducing the workload of construction workers.

[0011] Preferably, a supplementing mechanism is provided on the walking frame, and the supplementing mechanism includes a support frame and a storage box containing concrete, the support frame is fixedly connected to the walking frame, the storage box is connected to the support frame, and a plurality of discharge ports are provided at the bottom of the storage box, and the plurality of discharge ports are spaced apart along the width direction of the road.

[0012] By adopting the above technical solution, a storage box is arranged on the support frame, and a plurality of discharge ports are opened at the bottom of the storage box. After the accumulated concrete is initially leveled, when the amount of initially leveled concrete is insufficient and potholes appear, the concrete in the storage box can flow out of the storage box through the corresponding discharge ports, thereby replenishing the concrete and reducing the possibility of potholes appearing in the subsequent paving of the road surface due to insufficient amount of concrete for the road surface after initial leveling.

[0013] Preferably, the replenishing mechanism also includes a power assembly, the storage box is slidably connected to the support frame, the storage box slides along the width direction of the road, the power assembly is arranged on the support frame, and the power assembly is connected to the storage box to drive the storage box to move.

[0016] By adopting the above technical solution, a screw conveyor is used to extract the concrete accumulated in front of the push plate, and the concrete is transported to the storage box, so as to supplement the concrete in the storage box and reduce the possibility of manual replenishment of concrete; after the concrete is extracted, the amount of concrete accumulated in front of the push plate can be reduced, reducing the resistance encountered by the paver when moving forward.

[0017] Preferably, a material blocking plate is provided in the material storage box, and the material blocking plate is used to block part of the concrete in the material storage box.

[0018] By adopting the above technical solution, a material blocking plate is arranged in the material storage box, and the material blocking plate is used to block and support part of the concrete in the material storage box, thereby reducing the pressure of the concrete at the bottom of the material storage box, thereby reducing the possibility of excessive concrete pressure at the bottom of the material storage box causing excessive concrete to flow out of the discharge port.

[0019] Preferably, a support box is fixedly connected to the material storage box, and the material blocking plate is slidably connected to the support box. The material blocking plate slides in a direction perpendicular to the ground. A support spring is provided in the support box, and the support spring is fixedly connected between the support box and the material blocking plate to support the material blocking plate. The support spring applies a force away from the ground to the material blocking plate.

When the concrete in the material storage box presses the material blocking plate to contact the limit switch, the screw conveyor is in a closed state.

[0020] By adopting the above technical solution, a limit switch is set in the support box, and the concrete is used to press down the material blocking plate so that the material blocking plate contacts the limit switch in the support box. At this time, the screw conveyor is in a closed state. When the concrete in the storage box is reduced to a certain amount, the material blocking plate moves upward under the push of the support spring, and then the material blocking plate is separated from the limit switch, so that the screw conveyor starts and the concrete in the storage box is replenished, thereby realizing automatic replenishment of the concrete inside the storage box and improving the convenience of using the concrete paver.

[0022] By adopting the above technical scheme, the lifting rod is slidably connected to the supporting plate, and the sliding of the material storage box drives the lifting plate to slide synchronously. The sliding of the lifting plate first drives the lifting rod located on one side of its free end to rise, and the rising of the lifting rod drives the lifting rod and the compaction plate to rise. When the lifting plate continues to move and slide over the lifting rod, the compaction plate falls freely under the action of gravity to achieve compaction of the road surface. Then the material storage box drives the lifting plate to move back. When it contacts the lifting rod, the lifting plate rotates upward, so that the lifting plate passes over the lifting rod and returns to its position smoothly, and the next compaction can be carried out. Use multiple sets of compaction components to compact the concrete after preliminary leveling, so that the bubbles inside the concrete are compacted and escape, thereby reducing the bubble content in the road surface and improving the compactness of the road surface.

[0041] The following is combined with Figure 1-9 This application is described in further detail.

[0042] The embodiment of the present application discloses a concrete pavement paver suitable for continuous construction.

[0043] Reference Figure 1 A concrete pavement paver suitable for continuous construction includes a walking device 100, a leveling device 200 and a paving device 600. The leveling device 200 and the paving device 600 are both installed on the walking device 100. The walking device 100 is used to drive the leveling device 200 and the paving device 600 to move. The leveling device 200 is used to preliminarily level the concrete accumulated in the center of the road, and the paving device 600 is used to pave the preliminarily leveled concrete. After the concrete transport truck dumps the concrete on the road, the walking device 100 is used to drive the leveling device 200 and the paving device 600 to move along the road paving direction, and the leveling device 200 is used to push the concrete accumulated on the road surface to the side of the road, and the accumulated concrete is preliminarily leveled, and then the paving device 600 is used to spread the concrete, thereby reducing the possibility of construction workers manually leveling the accumulated concrete, thereby reducing the possibility of the paver waiting for manual labor to preliminarily level the concrete before paving, realizing continuous construction of the paver and improving the paving efficiency of the paver.

[0044] Reference Figure 1 The walking device 100 includes a walking frame 110, which is horizontally arranged, and four walking wheels 120 are rotatably connected below the walking frame 110. The four walking wheels 120 are respectively located near the four corners of the walking frame 110, and the rotation axes of the four walking wheels 120 are parallel to the width direction of the road. When paving the road surface, the walking wheels 120 at both ends of the walking frame 110 are respectively arranged on both sides of the road to support the walking frame 110.

[0045] Reference Figure 1 and Figure 2 The flattening device 200 includes a push plate 210 fixedly connected to the traveling frame 110. The push plate 210 is in a "V" shape and is vertically arranged. The middle part of the push plate 210 is inclined toward the forward direction of the traveling frame 110. The push plate 210 includes two inclined portions 211. A rotating rod 220 is rotatably connected to each inclined portion 211 on a side away from the traveling frame 110. A first spiral blade 230 is coaxially fixedly connected to the rotating rod 220. A rotating mechanism 240 is installed on the push plate 210. The rotating mechanism 240 is used to drive the two rotating rods 220 to rotate synchronously.

[0046] Reference Figure 1 and Figure 2The rotating mechanism 240 includes two first motors 241, and the two first motors 241 are fixedly connected to the push plate 210. The two first motors 241 are respectively close to the positions at both ends of the push plate 210. The two first motors 241 are arranged in a one-to-one correspondence with the two rotating rods 220. The main shaft of the first motor 241 is coaxially fixedly connected to the corresponding rotating rod 220. Two protective covers 242 are fixedly connected to the push plate 210. The two first motors 241 are respectively located in the two protective covers 242. The rotating rod 220 to which the main shaft of the first motor 241 is fixedly connected is rotatably connected to the protective cover 242 of the first motor 241. During the paving process, the movement of the walking frame 110 drives the push plate 210 to move. The "V" shape design of the push plate 210 allows the concrete accumulated in the center of the road to move along the push plate 210 to both sides of the road. At the same time, the two first motors 241 are used to drive the two rotating rods 220 to rotate respectively, and the first spiral blades 230 fixedly connected to the rotating rods 220 are used to increase the speed of the concrete moving to both sides, thereby achieving the initial leveling of the concrete and reducing the possibility of the construction workers having to manually level it.

[0047] Reference Figure 1 , Figure 3 and Figure 4A replenishing mechanism 300 is installed on the walking frame 110, and the replenishing mechanism 300 includes a support frame 310, the support frame 310 is horizontally arranged, and the support frame 310 is fixedly connected to a side of the walking frame 110 close to the push plate 210, and a storage box 320 is slidably connected in the support frame 310, and the upper end of the storage box 320 is open, and the storage box 320 includes a storage portion 321 and a discharging portion 322, and the discharging portion 322 is located at the lower end of the storage portion 321, and the discharging portion 322 and the storage portion 321 are integrally formed; both ends of the storage portion 321 in the length direction are fixedly connected with support rods 330, and the four support rods 330 are parallel to the length direction of the support frame 310, each support rod 330 is penetrated by the support frame 310, and the four support rods 330 are slidably connected to the support frame 310. The two side walls of the discharge part 322 in the width direction are inclined in the direction away from the storage part 321 to the direction close to each other, and the lower end of the discharge part 322 is provided with a plurality of discharge ports 340, and the plurality of discharge ports 340 are arranged at equal intervals along the width direction of the road, and the height of the discharge ports 340 is flush with the height of the paved concrete road surface. A power assembly 350 is installed on the support frame 310, and the power assembly 350 is used to drive the storage box 320 to swing left and right along the length direction of the support frame 310. The storage box 320 is slidably connected to the side of the push plate 210 close to the walking frame 110, and the height of the lower end of the storage box 320 is set at the height of concrete paving. After the push plate 210 performs preliminary flattening of the accumulated concrete, the concrete in the storage box 320 is used to supplement the position where the road surface concrete is less in number, so as to reduce the possibility of potholes in the subsequent paving road surface caused by insufficient concrete quantity on both sides of the road after the push plate 210 is pushed.

[0048] Reference Figure 1 , Figure 3 and Figure 4 The power assembly 350 includes a second motor 351 fixedly connected to the support frame 310, the main shaft of the second motor 351 is vertically fixedly connected to a connecting rod 352, the end of the connecting rod 352 away from the main shaft of the second motor 351 is hinged with a pushing rod 353, the hinge axis of the pushing rod 353 and the connecting rod 352 is parallel to the rotation axis of the second motor 351, the end of the pushing rod 353 away from the connecting rod 352 is hinged on the side wall of the storage box 320, and the hinge axis of the pushing rod 353 and the storage box 320 is parallel to the rotation axis of the main shaft of the second motor 351. The main shaft of the second motor 351 is rotated to drive the connecting rod 352 to rotate, and the rotation of the connecting rod 352 drives the pushing rod 353 to move, thereby realizing the left and right sliding of the storage box 320. The left and right sliding of the storage box 320 is utilized to increase the filling range of the discharge port 340. At the same time, the left and right sliding of the discharge box can increase the fluidity of the concrete in the storage box 320, thereby making the concrete evenly distributed in the storage box 320 to ensure the discharge of each discharge port 340.

[0049] Reference Figure 1 and Figure 3 A screw conveyor 400 is fixedly connected between the support frame 310 and the push plate 210. One end of the screw conveyor 400 feeds through the push plate 210 and then extends into the side of the push plate 210 away from the walking frame 110. The outer wall of the screw conveyor 400 is fixedly connected to the push plate 210, and the discharge port 340 of the screw conveyor 400 is located above the storage box 320. In the process of the push plate 210 being pushed by the walking frame 110 to move, more concrete will accumulate in the central position in front of the push plate 210. By setting one end of the screw conveyor 400 feed in front of the push plate 210, the concrete in front of the push plate 210 and the accumulated concrete can be transported to the storage box 320 through the screw conveyor 400, thereby supplementing the concrete in the discharge box, while reducing the amount of accumulated concrete in front of the push plate 210 and reducing the resistance to the paver moving forward.

[0050] Reference Figure 1 , Figure 4 and Figure 5 A support box 420 is fixedly connected to the material storage box 320, and the support box 420 is horizontally arranged, and the opening of the support box 420 faces upward, one end of the support box 420 in the width direction is fixedly connected to the inner side wall of the material storage box 320 in the width direction, and the two ends of the support box 420 in the length direction are respectively fixedly connected to the two inner side walls of the material storage box 320 in the length direction; a material blocking plate 410 is slidably connected to the support box 420, and the material blocking plate 410 slides in the vertical direction; a plurality of support springs 430 are installed in the support box 420, and the plurality of support springs 430 are spaced apart along the length direction of the material blocking plate 410, the lower end of each support spring 430 is fixedly connected to the support box 420, and the upper end of each support spring 430 is fixedly connected to the material blocking plate 410, and the support springs 430 are used to support the material blocking plate 410.

[0051] A limit switch 440 is fixedly connected inside the support box 420 , and the limit switch 440 is electrically connected to the screw conveyor 400 to control the opening and closing of the screw conveyor 400 . During the paving process of concrete, the concrete in the storage box 320 presses down the material blocking plate 410 so that the material blocking plate 410 contacts the limit switch 440. At this time, the screw conveyor 400 is in a closed state. When the concrete in the storage box 320 flows out from the discharge port 340 and the concrete in the storage box 320 is reduced to a certain amount, the material blocking plate 410 moves upward under the push of the support spring 430, and then the material blocking plate 410 is separated from the limit switch 440, so that the screw conveyor 400 starts and the concrete in the storage box 320 is replenished, which is convenient for controlling the amount of concrete in the storage box 320; at the same time, the material blocking plate 410 is used to support the concrete in the storage box 320, so as to reduce the possibility of excessive concrete pressure at the bottom of the storage box 320 causing too much concrete to flow out of the discharge port 340.

[0052] Reference Figure 4 and Figure 5 In order to facilitate the concrete above the material blocking plate 410 to slide off the material blocking plate 410, the upper end surface of the material blocking plate 410 is an inclined surface, and the height of the upper end surface of the material blocking plate 410 fixedly connected to the end of the support box 420 is higher than the height of the end away from the fixed connection support box 420. The inclined setting of the upper end surface of the material blocking plate 410 allows the concrete to slide down along the inclined surface of the material blocking plate 410, reducing the possibility of concrete accumulation on the material blocking plate 410.

[0053] Reference Figure 1 and Figure 6 A compaction mechanism 500 is provided on the traveling frame 110, and the compaction mechanism 500 includes a supporting plate 510 and a plurality of compaction components 520. The supporting plate 510 is fixedly connected to the traveling frame 110, and the supporting plate 510 is located on a side of the material storage box 320 away from the push plate 210; the plurality of compaction components 520 are all installed on the supporting plate 510, and the plurality of compaction components 520 are spaced apart along the width direction of the road.

[0054] Reference Figure 6 , Figure 7 and Figure 8 Each group of compaction components 520 includes a compaction plate 521, which is horizontally arranged. Two adjacent compaction plates 521 abut against each other. A lifting rod 522 is fixedly connected to the side of the compaction plate 521 away from the ground. The lifting rod 522 is vertically arranged. The lifting rod 522 is penetrated by the supporting plate 510. The lifting rod 522 is slidably connected to the supporting plate 510. The lifting rod 522 is vertically fixedly connected to a lifting rod 523 on the side wall close to the storage box 320. A rotating sleeve 524 is coaxially sleeved on the lifting rod 523, and the rotating sleeve 524 is rotatably connected to the lifting rod 523. A lifting plate 525 is installed on the side wall of the material storage box 320 away from the push plate 210. The lifting plate 525 is perpendicular to the side wall of the material storage box 320 connected thereto. One end of the lifting plate 525 in the length direction is rotatably connected to the side wall of the material storage box 320. The rotation axis of the lifting plate 525 is perpendicular to the side wall of the material storage box 320 connected to the lifting plate 525. One end of the lifting plate 525 away from its own rotation axis is inclined toward the direction close to the ground. A limiting block 526 is fixedly connected to the side wall of the material storage box 320. The limiting block 526 is located below the lifting plate 525. The limiting block 526 limits the inclination angle of the lifting plate 525.

[0055] During the process of paving concrete, when the second motor 351 drives the storage box 320 to slide, the storage box 320 also drives the lifting plate 525 to slide. By utilizing the inclined setting of the lifting plate 525, the rotating sleeve 524 on the lifting rod 523 corresponding to the lifting plate 525 rises along the inclined direction of the lifting plate 525, thereby driving the lifting rod 522 and the vibration plate 521 to rise. When one end of the lifting plate 525 hinged on the side wall of the storage box 320 slides over the lifting rod 523 and the rotating sleeve 524, the vibration plate 521 falls naturally under the action of gravity. The concrete is vibrated, and then the storage box 320 drives the lifting plate 525 to move back. When the bottom of the lifting plate 525 contacts the rotating sleeve 524, the rotating setting of the rotating sleeve 524 is used to rotate the lifting plate 525 upward, so that the lifting plate 525 passes over the lifting rod 523 and the rotating sleeve 524 and returns to its original position smoothly, and then the next vibration is carried out; the left and right sliding of the storage box 320 drives multiple vibration plates 521 to reciprocate and rise and fall, so as to realize the initial vibration of the concrete pavement, reduce the bubble content in the pavement, increase the compactness of the pavement, and then improve the pavement strength.

A first driving mechanism 640 is installed on the traveling frame 110, and the first driving mechanism 640 is used to drive the paving roller 610 to rotate. The first driving mechanism 640 is used to drive the paving roller 610 to rotate, so that the second spiral blade 620 on the paving roller 610 further flattens the concrete, thereby reducing the possibility that excessive concrete will flow out of the discharge port 340 of the storage box 320 and affect the flatness of the road surface. The two sections of the spiral blades have opposite rotation directions, which ensures the uniformity of the road paving while allowing the excess concrete to move to the positions on both sides of the road surface, so that the staff can shovel the excess concrete back into the storage box 320.

After the first leveling roller 630 performs the initial leveling on the road surface, the second driving mechanism 670 is used to drive the compacting roller 650 to rotate. Since the compacting roller 650 is eccentrically arranged, the compacting roller 650 can perform a secondary compaction on the road surface, so that the mortar in the concrete floats and the road surface strength is improved. At the same time, the first leveling roller 630 and the second leveling roller 660 are rotated to drive the traveling frame 110 to move, thereby realizing the driving of the traveling frame 110.

The third pulleys 672 and the corresponding fourth pulleys 673 are connected through a belt 644. The main shaft of the third motor 641 rotates to drive the two third pulleys 672 to rotate, and then the two fourth pulleys 673 are rotated through the transmission of the belt 644, thereby realizing the rotation of the compaction roller 650 and the second leveling roller 660.
