Description

Technical Field

[0001] The invention relates to the technical field of roadbed block laying, and more specifically, to an assembled roadbed block laying device and a laying method thereof. Background Art

[0002] Prefabricated roadbed, also known as prefabricated assembled roadbed, is a new type of roadbed construction method that uses factory production and modular design. In prefabricated roadbeds, hexagonal blocks are often used. Hexagonal blocks are a special shape of prefabricated concrete blocks. Compared with traditional rectangular or square blocks, they have the following advantages: 1. High corner strength: The joints of the sides of the hexagonal blocks in the plan view are greater than 90 degrees, which makes the corners stronger and helps to resist external loads; 2. Good interlocking effect: Hexagonal blocks can form a tighter interlocking structure, which improves the stability and bearing capacity of the overall structure.

[0003] At present, in the process of laying hexagonal blocks, two methods of laying and fastening blocks are generally used. The first method is that after laying each hexagonal block, the staff on the side uses a rubber hammer to first hammer the newly laid block from the side to the side of the already laid block to improve the fit between the blocks, and then hammer from the top of the block to improve the fit between the blocks and the soil. The second method is to first perform the laying operation as a whole, and after all the laying operations are completed, the laid hexagonal blocks are compacted as a whole by a roller and the flatness is measured. The second method is the main method of mechanized laying at present. For example, the Chinese utility model patent with authorization announcement number CN215366694U discloses an automatic hexagonal tile laying machine and the Chinese utility model patent with authorization announcement number CN214089364U discloses a rapid laying device for prefabricated block concrete. Although the above two patents realize the mechanical and automatic laying of hexagonal blocks, they are still However, there are the following defects: 1. At present, mechanical equipment uses two unrelated different equipment for split construction operations for laying and compacting hexagonal blocks, and the precision of split operation is poor; 2. Under the premise that hexagonal blocks have been laid in front, the position and angle of each hexagonal block to be laid later have precise requirements, but the current mechanical equipment does not clamp and limit the hexagonal blocks during laying, and the hexagonal blocks are likely to be not in a horizontal state during laying, which leads to inaccurate position of the hexagonal blocks. At the same time, the hexagonal blocks laid later cannot be close to the hexagonal blocks laid in front, and the laying effect is poor; 3. When the current mechanical equipment is laid, the height of the hexagonal blocks laid later does not refer to the height of the hexagonal blocks that have been laid. Each hexagonal block is laid separately, so it is easy for the height of the laid hexagonal blocks to be uneven. At this time, manual testing of the required compaction height and flatness is required, which further reduces the laying effect. Summary of the invention

[0010] Furthermore: the driving assembly includes two mounting sleeves fixedly installed on the bottom of the mounting frame, an electric push rod is installed between the two mounting sleeves, a push plate is fixedly installed on the output end of the electric push rod, an articulated frame is fixedly installed on the bottom of the push plate, two symmetrical connecting rods are hinged on the articulated frame, the two connecting rods are respectively hinged to the left and right two clamping plates, and a number of fixed rods are installed between the articulated frame and the clamping plate.

[0016] The present invention also provides a method for laying prefabricated roadbed blocks, which is completed in cooperation with the above-mentioned prefabricated roadbed block laying equipment, and includes the following steps: S1: the output end of the electric push rod pushes the push plate to move, driving the articulated frame to pull the connecting rod and the fixed rod to move, so that the clamping plate 1 and the clamping plate 2 move toward the side close to the hexagonal block, and clamp and fix three of the sides of the hexagonal block. At the same time, the pressing plate 1 and the pressing plate 2 respectively press and level the top center position and the top edge position of the hexagonal block, so that the hexagonal block can be clamped in a horizontal state.

[0017] S2: After the hexagonal blocks are pressed, leveled and clamped, the output end of the cylinder pushes the drive plate to drive the mounting frame to move, so that the three unclamped sides of the clamped hexagonal blocks are squeezed toward the side of the laid hexagonal blocks, so that the hexagonal blocks being laid are pressed against the laid hexagonal blocks to enhance the connection strength between the hexagonal blocks.

[0018] S3: After being pressed tightly, the articulated frame is driven to move so that the first clamp plate and the two second clamp plates are separated from the hexagonal blocks, and the first clamp plate and the second clamp plate limit the hexagonal blocks to avoid large horizontal displacement of the hexagonal blocks during the compaction process.

[0019] S4: The output shaft of the dual-axis motor rotates to drive the two eccentric wheels to rotate, causing the mounting frame to vibrate and transmit the vibration to the hexagonal blocks through the tamping plate, and the hexagonal blocks are vibrated and compacted. During the laying and compacting process, the bottom surface of the pressing plate 2 is used as a reference. As the hexagonal blocks being laid and compacted are gradually compacted downwards, when the bottom surface of the pressing plate 2 contacts with other laid hexagonal blocks, it means that the hexagonal blocks being laid have been compacted in place and are at the same height as other hexagonal blocks. There is no need to additionally measure the compaction height and flatness, thereby completing a single laying operation of the hexagonal blocks, and then repeating the above operations to achieve the paving of the road surface.

[0020] The beneficial effects of the present invention are as follows: 1. The present application is for laying hexagonal blocks. Through a drive, the clamping of the three lateral sides and the compaction and leveling of the top center position and the top edge position can be achieved simultaneously. The blocks are in a horizontal state and can cooperate with the laid hexagonal blocks through the second pressing plate to control the compaction height to ensure that the height of all blocks after laying is consistent. There is no need for additional manual measurement of the compaction height and flatness. In the entire laying process, the horizontal clamping, placement, and adhesion of the blocks and the self-referenced block compaction operations are integrated as a whole, and the laying accuracy of the blocks is high.

[0021] 2. The present application uses an extrusion and pressing unit to squeeze the three unclamped sides of the clamped hexagonal blocks toward the side of the laid hexagonal blocks, so that the hexagonal blocks being laid are pressed against the laid hexagonal blocks, which helps to reduce the gaps and unevenness of the road surface after paving and improves the laying accuracy of the road blocks.

[0022] 3. The present application controls the first and second plywoods to stop just when they are separated from the hexagonal blocks, so that there is a gap fit between the first and second plywoods and the hexagonal blocks. This gap fit makes the first and second plywoods limit the hexagonal blocks being laid, avoiding large horizontal displacement of the hexagonal blocks during the compaction process, resulting in insufficient fit with other hexagonal blocks that have been laid.

[0023] 4. In the process of laying and compacting, the height of the laid hexagonal blocks can be used as a reference. When the bottom surface of the pressure plate contacts other laid hexagonal blocks, it proves that the hexagonal blocks being laid are at the same height as other hexagonal blocks. At this time, the compaction operation is completed, which can ensure that the height of all hexagonal blocks after laying is consistent. There is no need for additional manual measurement of the compaction height and flatness, which greatly improves the laying accuracy and laying effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] See also Figure 2 , Figure 3 and Figure 5 The clamping assembly 302 includes three mounting plates 3021 fixedly mounted on the bottom of the mounting frame 1 and three support rods 3022 respectively fixedly mounted on one side of the three mounting plates 3021 close to the hexagonal building block 2, a clamping plate 1 3024 is slidably connected to the outer side of the middle support rod 3022, and a clamping plate 2 3025 is slidably connected to the outer side of the support rods 3022 on the left and right sides.

[0037] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 A circular plate 3023 is fixedly installed on the side of the support rod 3022 away from the mounting plate 3021, and a sliding rod 3026 is fixedly installed on the side of the clamping plate 1 3024 and the clamping plate 2 3025 close to their corresponding mounting plates 3021, and the sliding rod 3026 slides through the corresponding mounting plates 3021.

[0038] See also Figure 2 , Figure 3 and Figure 5 The driving component 301 includes two mounting sleeves 3011 fixedly mounted on the bottom of the mounting frame 1, an electric push rod 3012 is installed between the two mounting sleeves 3011, a push plate 3013 is fixedly mounted on the output end of the electric push rod 3012, a hinged frame 3014 is fixedly mounted on the bottom of the push plate 3013, two symmetrical connecting rods 3015 are hinged on the hinged frame 3014, the two connecting rods 3015 are hinged to the left and right two clamping plates 3025 respectively, and a plurality of fixing rods 3016 are installed between the hinged frame 3014 and the clamping plate 3024.

[0039] When in use, first connect the squeezing and pressing unit 6 to the external transfer device, then move the mounting frame 1 to the top of the hexagonal block 2 to be laid through the external transfer device, and align the first clamping plate 3024 and the second clamping plate 3025 with three sides of the hexagonal block 2, then start the electric push rod 3012, the output end of the electric push rod 3012 pushes the push plate 3013 to move backward, thereby driving the articulated frame 3014 to move backward, and the articulated frame 3014 will pull the connecting rod 3015 and its hinged end to move synchronously during the backward movement, thereby pulling the second clamping plate 3025 to move closer to the hexagonal block 2. At the same time, the articulated frame 30 The movement of 14 will also synchronously pull the plurality of fixing rods 3016 to move, thereby driving the clamping plate 1 3024 to move toward the side close to the hexagonal building block 2, and then the clamping plate 1 3024 and the two clamping plates 2 3025 clamp and fix three of the sides of the hexagonal building block 2. At the same time, the pressing assembly 401 cooperates with the clamping plate 1 3024 and the clamping plate 2 3025 to clamp the three lateral sides of the hexagonal building block 2 and press and level the top center position and the top edge position, so that the hexagonal building block 2 can be clamped in a horizontal state, and at the same time, the stability of the hexagonal building block 2 during the transfer process can be ensured to prevent the hexagonal building block 2 from shifting or falling.

[0040] When the transfer device transfers the clamped hexagonal building block 2 to the laying site, the three unclamped sides of the hexagonal building block 2 to be laid are first squeezed and pressed against the laid hexagonal building block 2 by the squeezing and pressing unit 6, and then the electric push rod 3012 is started, and the output end of the electric push rod 3012 drives the push plate 3013 to move forward, thereby driving the articulated frame 3014 to move forward. During the forward movement of the articulated frame 3014, the connecting rod 3015 and its hinged end will be pushed to move synchronously, thereby pushing the second clamping plate 3025 to move away from the hexagonal building block 2. At the same time, the movement of the articulated frame 3014 will also synchronously push the movement of several fixed rods 3016, thereby pushing the second clamping plate 3025 to move away from the hexagonal building block 2. , thereby making the clamping plate 1 3024 and the two clamping plates 2 3025 detach from the hexagonal building block 2. When the clamping plate 1 3024 and the two clamping plates 2 3025 just detach from the hexagonal building block 2, the electric push rod 3012 is stopped. At this time, the clamping fixation of the hexagonal building block 2 is released, but the clamping plate 1 3024 and the two clamping plates 3025 are in a clearance fit state with the hexagonal building block 2, thereby avoiding a large horizontal displacement of the subsequent hexagonal building block 2 during the laying process. Finally, the vibration component 502 controls the compaction component 501 to vibrate and compact the hexagonal building block 2 being laid. During the compaction process, the pressing component 401 cooperates with the laid hexagonal building block 2 to control the compaction height to ensure that the height of all hexagonal building blocks 2 after laying are consistent.

[0041] See also Figure 2 , Figure 4 and Figure 5 The pressing assembly 401 includes two spring telescopic rods 4011 fixedly mounted at the bottom of the fixing frame 7 and symmetrical to each other. A circular plate 4012 is installed at the telescopic ends of the two spring telescopic rods 4011. A plurality of square-distributed buffer springs 4013 are fixedly mounted at the bottom of the circular plate 4012. Two symmetrical pressing plates 4014 are fixedly mounted at the bottom ends of the plurality of buffer springs 4013. A trapezoidal plate 401 is fixedly mounted on the outer side of the circular plate 4012 through a plurality of connecting rods. 6. A plurality of buffer springs 4017 are fixedly installed at the bottom of the trapezoidal plate 4016, and a pressure plate 4018 is installed at the bottom of the plurality of buffer springs 4017. L-shaped plates 4019 are fixedly installed on the left and right sides of the fixing frame 7. A limiting rod 4015 that slides through the circular plate 4012 and the L-shaped plate 4019 is fixedly installed on the top of the two pressure plates 4014. A limiting rod 4010 that slides through the trapezoidal plate 4016 and the mounting frame 1 is fixedly installed on the top of the pressure plate 4018.

[0042] See also Figure 2 , Figure 4 and Figure 5 The control assembly 402 includes two fixed plates 4021 fixedly installed on the left and right sides of the clamping plate 3024, a wedge plate 4022 is fixedly installed on the side of the fixed plate 4021 close to the hexagonal building block 2, and a wedge platform 4023 matching the corresponding wedge plate 4022 is fixedly installed on the top of the two pressure plates 4014.

[0043] When in use, when the articulated frame 3014 moves and pulls the fixed rods 3016 to move, and drives the clamping plate 3024 to move toward the side close to the hexagonal building block 2, it will also drive the fixed plate 4021 to move toward the side close to the hexagonal building block 2, thereby driving the wedge plate 4022 to move accordingly. During the movement of the wedge plate 4022, it will first contact the wedge platform 4023 and squeeze the wedge platform 4023 as the wedge plate 4022 continues to move, thereby driving the wedge platform 4023 to move downward, and then driving the circular plate 4012 to move downward, so that the pressing plate 4014 moves downward, presses the surface of the hexagonal building block 2 and compresses the buffer spring 401 3. The top center of the hexagonal building block 2 is pressed by the pressing plate 1 4014, so that the top surface of the hexagonal building block 2 can fit with the pressing plate 1 4014. At the same time, the downward movement of the circular plate 4012 will drive the trapezoidal plate 4016 to move downward synchronously through a number of connecting rods, thereby driving the pressing plate 2 4018 to move downward to press the top edge of the hexagonal building block 2 and compress the buffer spring 2 4017, and then the pressing plate 1 4014, the pressing plate 2 4018, the clamping plate 1 3024 and the clamping plate 2 3025 cooperate to clamp the three lateral sides of the hexagonal building block 2 and press and level the top center position and the top edge position, so that the hexagonal building block 2 can be clamped in a horizontal state, and the height of the laid hexagonal block 2 can be used as a reference in the subsequent laying and compacting process. As the hexagonal block 2 being laid and compacted is gradually compacted downward, when the bottom surface of the pressing plate 2 4018 contacts with other laid hexagonal blocks 2, it means that the hexagonal block 2 being laid has been compacted in place and is at the same height as other hexagonal blocks 2, thereby further ensuring that the height of all hexagonal blocks 2 after laying is consistent, without the need to additionally measure the compacted height and flatness, thereby improving the laying accuracy and laying efficiency. When the bottom of the wedge plate 4022 contacts the top of the wedge platform 4023, the wedge plate 4022 continues to Continued movement will no longer squeeze the wedge-shaped platform 4023 to move downward. It should be noted that when the pressure plate 4018 presses the top edge of the hexagonal building block 2, a portion of the bottom of the pressure plate 4018 will leak out and not contact the hexagonal building block 2, so as to control the distance the hexagonal building block 2 is compacted and moved downward during the subsequent compaction process. It should be noted that the pressure applied by the buffer spring 4013 and the buffer spring 4017 on the top of the hexagonal building block 2 is less than the lateral clamping force applied by the clamping plate 3024 and the clamping plate 3025 on the hexagonal building block 2, so the hexagonal building block 2 will not fall off from between the clamping plate 3024 and the clamping plate 3025 under the action of pressure.

[0044] After the transfer equipment transfers the clamped hexagonal building block 2 to the laying site, the three unclamped sides of the hexagonal building block 2 to be laid are pressed and pressed against the laid hexagonal building block 2, and then the clamping and fixing of the hexagonal building block 2 are released, and the clamping plates 1 3024 and 2 3025 are in a clearance fit state with the hexagonal building block 2. This clearance fit state enables the clamping plates 1 3024 and 2 3025 to limit the hexagonal building block 2 being laid, thereby preventing the hexagonal building block 2 from having a large horizontal deviation during the subsequent compaction process, resulting in an insufficient fit with other hexagonal building blocks 2 that have been laid. At this time, the wedge plate 4022 is still pressed on the top of the wedge platform 4023, and the pressing plate 1 4014 and the pressing plate The second pressing plate 4018 presses the hexagonal building block 2 on the ground, and at this time, the bottom of the second pressing plate 4018 does not contact with other hexagonal building blocks 2 that have been laid. Then, the vibration component 502 controls the compacting component 501 to vibrate and compact the hexagonal building block 2 being laid. During the laying and compacting process, the height of the laid hexagonal building block 2 is used as a reference. As the hexagonal building block 2 being laid and compacted is gradually compacted downward, when the bottom surface of the second pressing plate 4018 contacts with other hexagonal building blocks 2 that have been laid, it means that the hexagonal building block 2 being laid has been compacted into place and is the same height as other hexagonal building blocks 2. There is no need to additionally measure the compaction height and flatness, thereby completing a single laying operation of the hexagonal building block 2.

[0045] See also Figure 1 and Figure 8 The extrusion and pressing unit 6 includes a slide groove 601 opened on the top of the mounting frame 1 and a slider 602 slidably connected in the slide groove 601, a connecting plate 603 is fixedly installed on the top of the slider 602, a cylinder 604 is fixedly installed on the top of the connecting plate 603, a driving plate 605 is fixedly installed on the top of the mounting frame 1, the output end of the cylinder 604 is fixedly connected to the driving plate 605, and a connecting shaft 606 connected to an external transfer device is rotatably installed on the top of the connecting plate 603.

[0046] In specific use, when the transfer device transfers the clamped hexagonal building block 2 to the paving site, the cylinder 604 is started, and the output end of the cylinder 604 pushes the driving plate 605 to move backward, thereby driving the mounting frame 1 to move backward, and then driving the three unclamped sides of the clamped hexagonal building block 2 to be squeezed toward the side of the laid hexagonal building block 2, so that the hexagonal building block 2 being laid is close to the laid hexagonal building block 2, which helps to reduce the gaps and unevenness of the road surface after paving, improve the integrity of the road surface, and at the same time When the hexagonal blocks 2 are in full contact with each other, extrusion is used to ensure that the connection strength between the hexagonal blocks 2 is not only enhanced, but also helps to disperse the load, improve the bearing capacity and stability of the road, and thus greatly reduce the deformation and damage of the road caused by factors such as vehicle driving and climate change. Then, the clamping of the hexagonal blocks 2 is released, and the gap between the hexagonal blocks 2 is limited. Finally, the vibration component 502 is used to control the compaction component 501 to vibrate and compact the hexagonal blocks 2 being laid to complete a single laying operation.

[0047] See also Figure 2 , Figure 6 and Figure 7 The compacting assembly 501 includes a spring telescopic rod 5011 fixedly mounted at the bottom of the fixed frame 7 and a reciprocating plate 5012 fixedly mounted at the telescopic end of the spring telescopic rod 5011. A vibration frame 5013 is fixedly mounted on the outer side of the reciprocating plate 5012. A compacting plate 5014 for compacting the hexagonal building blocks 2 is fixedly mounted at the bottom of the vibration frame 5013.

[0048] See also Figure 2 , Figure 6 and Figure 7 The vibration assembly 502 includes two support plates 5021 fixedly installed at the bottom of the reciprocating plate 5012 and symmetrically arranged on the left and right, a rotating sleeve 5022 is rotatably installed between the two support plates 5021, a swing rod 5023 is fixedly installed at the bottom of the rotating sleeve 5022, a dual-axis motor 5025 is fixedly installed at the bottom of the swing rod 5023 through a motor sleeve 5024, eccentric wheels 5026 are fixedly installed at both ends of the output shaft of the dual-axis motor 5025, hinged seats 5027 are fixedly installed on the front and rear inner walls of the vibration frame 5013, hinged seats 5028 are fixedly installed on the front and rear sides of the motor sleeve 5024, and a vibration spring 5029 is hingedly connected between the corresponding hinged seats 1 5027 and the hinged seats 2 5028.

[0049] When in use, when the hexagonal block 2 being laid is pressed against the laid hexagonal block 2 and the clamping of the hexagonal block 2 is released, and the gap of the hexagonal block 2 is limited, the double-axis motor 5025 is started, and the output shaft of the double-axis motor 5025 rotates to drive the two eccentric wheels 5026 to rotate at high speed. During the high-speed rotation of the eccentric wheels 5026, since the center of mass and the center of rotation do not coincide, centrifugal force is generated. The centrifugal force is transmitted to the mounting frame 1 through the swing rod 5023, the rotating sleeve 5022, the support plate 5021 and the vibration spring 5029, so that the mounting frame 1 vibrates, and the vibration of the mounting frame 1 is transmitted to the hexagonal block 2 through the tamping plate 5014. Thereby, vibration compaction of the hexagonal blocks 2 is achieved. Vibration compaction can further improve the fit between the hexagonal blocks 2 and the foundation or the laid hexagonal blocks 2, reduce gaps and voids, and further improve the stability of the overall structure. At the same time, compaction can ensure that the hexagonal blocks 2 achieve the expected flatness during the laying process, reduce road bumps and vehicle driving discomfort caused by the unevenness of the hexagonal blocks 2, and during the vibration compaction process, the vibration wave will be transmitted to the soil, causing the soil particles to rearrange and fill the gaps between the hexagonal blocks 2 and the soil to form a close contact, while making the soil more compact, thereby further improving the bearing capacity of the paved road surface.

[0050] See also Figures 1 to 9 In this embodiment, a method for laying assembled roadbed blocks is proposed, which is completed by using the above-mentioned assembled roadbed block laying equipment, and includes the following steps: S1: the output end of the electric push rod 3012 pushes the push plate 3013 to move, driving the articulated frame 3014 to pull the connecting rod 3015 and the fixing rod 3016 to move, so that the clamping plate 1 3024 and the clamping plate 2 3025 move toward the side close to the hexagonal block 2, and clamp and fix three of the sides of the hexagonal block 2. At the same time, the pressing plate 1 4014 and the pressing plate 2 4018 respectively press and level the top center position and the top edge position of the hexagonal block 2, so that the hexagonal block 2 can be clamped in a horizontal state.

[0051] S2: After the hexagonal building block 2 is pressed, leveled and clamped, the output end of the cylinder 604 pushes the driving plate 605 to drive the mounting frame 1 to move, so that the three unclamped sides of the clamped hexagonal building block 2 are squeezed toward the side of the laid hexagonal building block 2, so that the hexagonal building block 2 being laid is close to the laid hexagonal building block 2, so as to enhance the connection strength between the hexagonal building blocks 2.

[0052] S3: After being pressed tightly, the articulated frame 3014 is driven to move so that the first clamp plate 3024 and the two second clamp plates 3025 are separated from the hexagonal building block 2, and the first clamp plate 3024 and the second clamp plate 3025 limit the hexagonal building block 2 to avoid a large horizontal displacement of the hexagonal building block 2 during the compaction process.

[0053] S4: The output shaft of the dual-axis motor 5025 rotates to drive the two eccentric wheels 5026 to rotate, causing the mounting frame 1 to vibrate and transmit the vibration to the hexagonal building block 2 through the tamping plate 5014, thereby vibrating and compacting the hexagonal building block 2. During the laying and compacting process, the height of the laid hexagonal building block 2 is used as a reference. As the hexagonal building block 2 being laid and compacted is gradually compacted downward, when the bottom surface of the pressing plate 2 4018 contacts with other laid hexagonal building blocks 2, it means that the hexagonal building block 2 being laid has been compacted into place and is at the same height as other hexagonal building blocks 2. There is no need to additionally measure the compaction height and flatness, thereby completing a single laying operation of the hexagonal building block 2, and then repeating the above operation to achieve the paving of the road surface.

[0054] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
