Description

Technical Field

[0001] The present invention relates to the technical field of engineering equipment, and in particular to a road slab paving vehicle and a rapid paving system for foldable road slabs. Background Art

[0002] Prefabricated pavement panels are the primary construction equipment for rapid repairs and emergency response at temporary airports and natural disaster relief sites like earthquakes and floods. They are used in airport pavement repairs and emergency site paving. The installation of prefabricated pavement panels primarily relies on manual lifting, positioning, and installation. While the use of CASE engineering vehicles, cranes, and other equipment can somewhat reduce the workload of moving pavement panels, delicate tasks such as adjusting the panel's posture, positioning, and aligning holes still require manual labor, which is time-consuming and lacks precision. Accelerating the mechanization of pavement panel installation can reduce the need for personnel and significantly improve the efficiency and quality of pavement repairs and emergency site paving. Currently, equipment such as traveling frames are used to lift and install prefabricated concrete pavement panels, gradually increasing the degree of mechanization in construction and reducing manual labor. For example, Patent No. CN217499867U relates to a hydraulic lifting support structure for pavement panel installation. It is characterized by being installed on the upper ends of two sets of pavement panel walking mechanisms for prefabricated concrete pavement panels. Through components such as longitudinal beams, transverse beams, heightening sections, rotating longitudinal beam assemblies, and jacks, it facilitates support of prefabricated pavement surfaces with height differences, making height difference adjustment more convenient and safer, and increasing the ease and stability of adjustment. Patent No. CN217399342U relates to a pavement panel leveling robot. It is characterized by being able to adjust the height and inclination angle of the pavement panel by threading an adjustment screw onto the pavement panel and installing an adjuster on the lifting frame to turn the adjustment screw. The robot can adjust the length of the adjustment screw extending from the bottom of the pavement panel.

[0003] During the construction process of emergency repairs, foldable pavement panels have a larger square area per group than precast concrete slab pavement panels. The foldable pavement panels are connected by the panels to form a larger coverage area. The number of ground anchor holes is reduced, which can reduce the workload of ground anchoring, reduce the demand for personnel, and greatly improve the efficiency of emergency repair installation. Therefore, foldable pavement panels are more suitable for emergency repair construction. At present, the processes of unfolding and paving small-sized foldable pavement panels can still be manually assisted by equipment such as cranes to reduce the intensity of manual lifting operations. However, for large-sized foldable pavement panels, cranes cannot operate because they exceed the construction height. The above inventions are all for precast concrete slab pavement panels, and cannot unfold and pave foldable pavement panels. Therefore, there is an urgent need for a device that can move, unfold and pave foldable pavement panels. Summary of the Invention

[0004] The present invention provides a road slab paving vehicle to solve the technical problem that existing equipment is difficult to move, unfold and pave large-sized road slabs.

[0005] According to one aspect of the present invention, a road panel paving vehicle is provided, comprising: a road panel carrier, which is provided with a walking system; a road panel support frame, which is provided on the road panel carrier, the road panel support frame is used to provide support for the foldable road panel, and the length direction of the road panel support frame is arranged along the folding edge direction of the road panel; two end clamping assemblies are provided on the road panel support frame along the length direction of the road panel, and the two end clamping assemblies jointly clamp the road panel on the road panel support frame; an elastic clamping assembly, which is located between the two end clamping assemblies, and the elastic clamping assembly includes a support and a clamping rod, the support is provided on the road panel support frame, and a first hinge axis parallel to the folding edge of the foldable road panel is provided on the support, the clamping rod is hinged to the support through the first hinge axis, and an elastic member is provided on the support, and the clamping rod rotates around the hinge axis under the action of the elastic member and is pressed against the foldable road panel.

[0006] By adopting the above technical solution, the folded road panel can be placed on the road panel support frame when in use, and the two end clamping assemblies are respectively clamped at the two ends of the road panel to position the road panel and prevent the road panel from tipping over or falling from the road panel support frame during movement; because the road panel is continuously folded in a "W" shape, the elastic clamping assembly is set to ensure that the road panel can be folded and unfolded step by step during the unfolding process, and the clamping rod is pressed against the side of the foldable road panel under the action of the elastic member, so that the foldable road panel will not automatically unfold in a natural state. When the starting end of the folding road surface is pulled by external force, the first folding road panel will overcome the resistance of the elastic part and unfold, and compress the elastic part. When the first folding road panel passes the clamping rod, the elastic part rebounds and resets the clamping rod, so that the clamping rod presses the second folding road panel. Through this arrangement, the folding road panel can only be unfolded once at a time, which is convenient for laying the folding road panel; in the process of unfolding the road panel, the road panel carrier moves along the preset route with the road panel support frame, so that the unfolded road panel is laid on the panel, realizing the function of quickly moving, unfolding and laying the folding road panel.

[0007] Optionally, the elastic member includes: a connecting rod, a second hinge axis parallel to the first hinge axis is provided on the connecting rod, and the connecting rod is hinged to the clamping rod through the second hinge axis; a sliding sleeve, which is sleeved on the connecting rod, and the sliding sleeve slides with the connecting rod along the length direction of the connecting rod, and a second hinge axis parallel to the first hinge axis is provided on the sliding sleeve, and the sliding sleeve is hinged to the clamping rod through the second hinge axis; a first spring, which is sleeved on the connecting rod, and both ends of the first spring are respectively supported on the second hinge axis and the third hinge axis.

[0008] By adopting the above technical solution, when the clamping rod is pushed by the road panel, it will rotate around the first hinge axis, thereby driving the sliding sleeve to move on the connecting rod, causing the sliding sleeve to compress the first spring on the connecting rod. At the same time, the angle of the connecting rod and the angle between the clamping rod and the connecting rod will change accordingly. Through such a setting, the pressure on the first spring is always axial, which can avoid the uneven force on the first spring causing the first spring to bend and deform, thereby ensuring stability during long-term use.

[0009] Optionally, a roller is rotatably connected to the clamping rod, a rotation center line of the roller is parallel to the first hinge axis, and the third hinge axis is located between the roller and the second hinge axis.

[0010] By adopting the above technical solution, when the road panel is unfolded, the road panel will slide relative to the clamping rod. By setting the roller, the sliding friction is converted into rolling friction, which can reduce friction, slow down the wear of the elastic clamping component, and extend the service life.

[0011] Optionally, the road panel support frame includes a supporting portion and a leaning portion, the supporting portion is used to support the foldable road panel, the elastic clamping assembly and the end clamping assembly are arranged on the leaning portion, and a support roller is rotatably connected to the supporting portion, and the rotation center line of the support roller is perpendicular to the first hinge axis space.

[0012] By adopting the above technical solution, when the foldable road panel is placed on the road panel support frame, the support roller directly supports the road panel. When the clamping member pushes the road panel to move on the road panel support frame to adjust its position, there is rolling friction between the road panel and the support roller, and the friction force is small, which can slow down the wear of the road panel support frame.

[0013] Optionally, the road panel support frame includes: a center frame, connected to the road panel carrier and located in the travel direction of the road panel carrier; a left frame, hinged to the center frame, and the hinge axis of the left frame and the center frame is perpendicular to the folding edge of the foldable road panel; a right frame, hinged to the center frame, and the hinge axis of the right frame and the center frame is perpendicular to the folding edge of the foldable road panel; by rotating the left frame and the right frame, the road panel support frame is switched between the expanded state and the folded state. When the road panel support frame is in the expanded state, the left frame, the right frame and the center frame are all located in the travel direction of the road panel carrier to support the foldable road panel; when the road panel support frame is in the folded state, the center frame is located in the travel direction of the road panel carrier, and the left frame and the right frame are respectively located on both sides of the travel direction of the road panel carrier.

[0014] By adopting the above technical solution, during the construction process, the road panel support frame is in an expanded state to support large-sized road panels. When working in a narrow space or during transportation and transfer, the road panel support frame can be folded by folding the left and right frames to reduce the width of the entire machine. It can meet the needs of different working conditions and has a wide range of applications.

[0015] Optionally, the end clamping member includes: a telescopic bracket, which slides with the road panel support frame along the length direction of the road panel support frame; a baffle, which is fixedly connected to the telescopic bracket, and the baffle is perpendicular to the folding edge direction of the road panel; a telescopic cylinder, which is arranged along the folding edge direction of the road panel, one end of the telescopic cylinder is fixedly connected to the baffle, and the other end of the telescopic cylinder is fixedly connected to the road panel support frame.

[0016] By adopting the above technical solution, the telescopic cylinder can drive the baffle to move when it is extended and retracted, and the telescopic support can guide the movement of the baffle and provide support for the baffle. The telescopic cylinders of the two end clamps can be used in conjunction with each other, so that the two telescopic cylinders can be extended and retracted synchronously to clamp the road panel on the road panel support frame, or the two telescopic cylinders can be extended and retracted asynchronously to push the road panel to slide on the road panel support frame to adjust the position of the road panel.

[0017] Optionally, a buffer assembly is provided on the baffle, and the buffer assembly includes: a buffer block, which is used to contact the unfolded part of the foldable road panel to slow down the unfolding speed of the foldable road panel; a spring pressing device, which is provided on the baffle and is used to provide elastic support for the buffer block, and the force of the spring pressing device on the buffer block causes the buffer block to tend to move away from the baffle; the foldable road panel located on the road panel support frame contacts the buffer block during the unfolding process, and the foldable road panel unfolds after overcoming the damping of the spring pressing device.

[0018] By adopting the above technical solution, during the process of road panel deployment, if the speed of the road panel is too fast, it may collide violently with the bottom surface under the action of inertia, causing damage to the road panel, and at the same time being not conducive to the positioning of the road surface, affecting the accuracy of road panel paving; by setting buffer blocks and spring compression parts, the movement of the road panel deployment can be slowed down, thereby improving the safety and accuracy of road panel paving.

[0019] Optionally, the spring compression device includes: a sleeve, fixedly connected to the baffle; a connecting column, one end of which is fixedly connected to the buffer block, and the other end of which is slidably inserted into the sleeve; and a second spring, arranged in the sleeve, which provides support for the connecting column.

[0020] By adopting the above technical solution, the sleeve can position and protect the second spring, so that the second spring will not deviate from the axis and bend during operation. Optionally, multiple spring compression devices are provided between the road panel support frame and the buffer block, so that the buffer block is subjected to a more balanced force.

[0021] Optionally, a guide rod is provided at one end of the connecting column located in the sleeve, and the guide rod extends through the sleeve along the length direction of the connecting column to the outside of the sleeve. The guide rod slides with the sleeve, and a stop protrusion is provided at one end of the guide rod located in the sleeve block.

[0022] By adopting the above technical solution, the guide rod can guide the connecting column to prevent the connecting column from deviating during the sliding process. At the same time, the stop protrusion can limit the sliding stroke of the connecting column to prevent the connecting column from detaching from the sleeve.

[0023] According to another aspect of the present invention, a rapid laying system for foldable road panels is also provided, including a panel transport and laying vehicle and the above-mentioned road panel laying vehicle, the panel transport and laying vehicle including: a panel carrier, on which a walking system is provided; a lifting device, arranged on the panel carrier, the lifting device including a lifting seat and a driving member for driving the lifting seat to lift and lower; a swing arm, arranged on the lifting seat, with a laying frame suspended on the swing arm, and a suction cup for adsorbing the panels is provided on the side of the laying frame close to the bottom surface.

[0024] By adopting the above technical solution, during construction, the panels are first sucked up by the panel transport and paving vehicle and laid on both sides of the roadbed, and then the road panels are laid by the road panel paving vehicle so that the installation holes on the road panels correspond to the holes on the panels, so that the road panels can be quickly anchored.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The pavement panel carrier can drive the pavement panel support frame to move, and then drive the foldable pavement panel on the pavement panel support frame to move. The two end clamping assemblies are respectively clamped at both ends of the pavement panel to position the pavement panel to prevent the pavement panel from tipping over or falling off the pavement panel support frame during movement;

[0027] 2. By setting up an elastic clamping assembly, the clamping rod is pressed against the side of the foldable road panel under the action of the elastic member, so that the foldable road panel will not unfold automatically in a natural state. When the starting end of the foldable road surface is pulled by external force, the first folding road panel will overcome the resistance of the elastic member and unfold, and compress the elastic member. When the first folding road panel passes over the clamping rod, the elastic member rebounds and resets the clamping rod, so that the clamping rod presses the second folding road panel. Through this setting, the folding road panel can only unfold one fold at a time, which is convenient for laying the folding road panel.

[0028] In addition to the above-described objects, features and advantages, the present invention has other objects, features and advantages. The present invention will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0045] The following is combined with Figure 1-12 This application is described in further detail.

[0046] Reference Figure 1 The embodiment of the present application discloses a rapid laying system for a foldable road panel 1, including a road panel laying vehicle 2 and a panel transporting and laying vehicle 3, wherein the road panel laying vehicle 2 is used to lay the road panel 1, and the panel transporting and laying vehicle 3 is used to lay the panels 4.

[0047] Reference Figure 2 The road panel laying vehicle 2 includes a road panel carrier 5 and a road panel support frame 6 mounted on the road panel carrier 5. The road panel support frame 6 is used to support and unfold the folded road panels. The road panel carrier 5 is provided with a traveling system that can drive the road panel support frame 6 to move. The road panel carrier 5 is provided with a lifting mechanism and a sliding mechanism. The lifting mechanism can drive the road panel support frame 6 to rise and fall, and the sliding mechanism can drive the road panel support frame 6 to slide in four directions: front, back, left, and right. In a specific embodiment, the road panel carrier 5 is a forklift, and the sliding mechanism and the lifting mechanism are built-in structures of the forklift.

[0048] Reference Figure 3The length direction of the road panel support frame 6 is arranged along the folding edge direction of the road panel. The road panel support frame 6 includes a center frame 61, a left frame 62 and a right frame 63. The left frame 62, the center frame 61 and the right frame 63 are arranged in sequence along the length direction of the road panel support frame 6, wherein the center frame 61 is connected to the road panel carrier 5, the left frame 62 and the right frame 63 are hinged to the center frame 61 respectively, the hinge axis of the left frame 62 and the center frame 61 is perpendicular to the folding edge of the foldable road panel 1, and the hinge axis of the right frame 63 and the center frame 61 is perpendicular to the folding edge of the foldable road panel 1. By rotating the left frame 62 and the right frame 63, the road panel support frame 6 can be switched between the expanded state and the folded state. When the road panel support frame 6 is in the expanded state, the left frame 62 and the right frame 63 and the center frame 61 are all located in the direction of travel of the road panel carrier 5. When the road panel support frame 6 is in the folded state, the center frame 61 is located in the direction of travel of the road panel carrier 5, and the left frame 62 and the right frame 63 are respectively located on both sides of the direction of travel of the road panel carrier 5, so that the width of the whole machine is compressed to facilitate construction or transportation and transshipment in narrow scenes. The front brackets of the right frame 63, the center frame 61, and the left frame 62 of the road panel paving vehicle 2 are on the same plane. This can provide stable side support for the road panel. In actual use, the height of the front brackets of the right frame 63, the center frame 61, and the left frame 62 is set according to the width of the first folded road panel.

[0049] The center frame 61, left frame 62, and right frame 63 have similar structures, each including a supporting portion and a resting portion. The supporting portion is located at the bottom of the foldable road panel 1 and is used to support the weight of the foldable road panel 1. The resting portion is located on the side of the foldable road panel 1 close to the road panel carrier 5 and is used to support the foldable road panel 1 to prevent it from tipping over or falling. A support roller 65 is rotatably connected to the supporting portion, and the rotation centerline of the support roller 65 is perpendicular to the folding edge space of the foldable road panel 1. The foldable road panel 1 contacts the support roller 65. When the foldable road panel 1 moves left and right, the support roller 65 rolls with it to reduce friction.

[0050] A fork plate 64 is provided on the side of the supporting part away from the road panel carrier 5. The fork plate 64 is hinged to the supporting part, and the hinge axis is parallel to the length direction of the road panel support frame 6. When working, the fork plate 64 is in a horizontal state. When not working, the fork plate 64 can be folded upward by rotating it to reduce space occupancy.

[0051] Reference Figure 2The supporting part of the road panel support frame 6 is provided with an end clamping component 7 and an elastic clamping component 8 for clamping the road panel, wherein two end clamping components 7 are provided, one end clamping component 7 is provided at the end of the left frame 62, and the other end clamping component 7 is provided at the end of the right frame 63; any number of elastic clamping components 8 can be provided on the road panel support frame 6, and it can be understood that the elastic clamping components 8 can be provided on the center frame 61, the left frame 62 and the right frame 63, or the elastic clamping component 8 can be provided on only one of them.

[0052] Reference Figure 4 The elastic clamping assembly includes a support 81 and a clamping rod 82. The support 81 is arranged on the road panel support frame 6. The support 81 is provided with a first hinge shaft 83 parallel to the folding edge of the folding road panel 1. The clamping rod 82 is hinged to the support 81 through the first hinge shaft 83. An elastic member is provided on the support 81. Under the action of the elastic member, the clamping rod 82 rotates around the hinge shaft and is pressed against the folding road panel 1. The elastic member includes a connecting rod 84 and a first spring 87 sleeved on the connecting rod 84. A second hinge axis 85 parallel to the first hinge axis 83 is provided on the connecting rod 84, and the connecting rod 84 is hinged to the support 81 through the second hinge axis 85; a sliding sleeve 86 is sleeved on the connecting rod 84, and the sliding sleeve 86 slides with the connecting rod 84 along the length direction of the connecting rod 84. A third hinge axis 89 parallel to the first hinge axis 83 is provided on the sliding sleeve 86, and the sliding sleeve 86 is hinged to the clamping rod 82 through the third hinge axis 89. The two ends of the first spring 87 are respectively supported on the second hinge axis 85 and the third hinge axis 89.

[0053] The clamping rod 82 is pressed against the side of the foldable road panel 1 under the action of the elastic member, so that the foldable road panel 1 will not unfold automatically in a natural state. When the foldable road panel 1 is laid, the external force pulls the starting end of the folding road surface so that the first folding road panel overcomes the resistance of the elastic member and unfolds. In the process of unfolding the road panel, the clamping rod 82 is pushed by the road panel and rotates around the first hinge shaft 83, thereby driving the sliding sleeve 86 to move on the connecting rod 84, so that the sliding sleeve 86 compresses the first spring 87 on the connecting rod 84; when the first folding road panel passes over the clamping rod 82, the first spring 87 rebounds and resets the clamping rod 82, so that the clamping rod 82 presses the second folding road panel, and this process is repeated continuously during the unfolding of the road panel, so that the folding road panel 1 is only unfolded once each time.

[0054] A roller 88 is rotatably connected to the clamping rod 82, and the rotation center line of the roller 88 is parallel to the first hinge axis 83. The third hinge axis 89 is located between the roller 88 and the second hinge axis 85. When the road panel is unfolded, the road panel contacts the roller 88 and drives the roller 88 to rotate. There is rolling friction between the roller 88 and the road panel, and the friction force is relatively small.

[0055] Reference Figure 5When the pavement panel support frame 6 is in the expanded state, the two end clamping assemblies 7 are respectively located at the two ends of the foldable pavement panel 1, and the two ends cooperate to clamp the foldable pavement panel 1. The end clamping components include a telescopic bracket 71, a baffle 72, and a telescopic cylinder 73. The telescopic bracket 71 slides with the pavement panel support frame 6 along the length direction of the pavement panel support frame 6. The baffle 72 is fixedly connected to the telescopic bracket 71 and is perpendicular to the folding edge of the pavement panel. The telescopic cylinder 73 is arranged along the length direction of the pavement panel. One end of the telescopic cylinder 73 is fixedly connected to the baffle 72, and the other end of the telescopic cylinder 73 is fixedly connected to the pavement panel support frame 6. The telescopic cylinder 73 is driven by the power of the pavement panel carrier 5. When the telescopic cylinder 73 is extended or retracted, it can drive the baffle 72 to slide left and right on the pavement panel support frame 6. After the folded road panel is placed on the road panel support frame 6, if the position of the road panel needs to be adjusted, the corresponding telescopic cylinder 73 can be started to move the corresponding baffle 72, thereby pushing the road panel to slide left and right on the road panel support frame 6; when the position of the road panel does not need to be adjusted, the two cylinders can be started to make the two baffles 72 respectively abut against the ends of the road panel to clamp the road panel.

[0056] Reference Figure 6 The folding plate 72 is provided with a buffer assembly, which includes a buffer block 74 and a spring pressing device. The buffer block 74 is used to contact the unfolded part of the foldable road panel 1 to slow down the unfolding speed of the foldable road panel 1; the spring pressing device is provided on the baffle 72, and the top surface of the buffer block 74 protrudes from the baffle 72. The spring pressing device provides elastic support for the buffer block 74 to realize automatic fitting of the buffer block 74 and the road panel. The force of the spring pressing device on the buffer block 74 causes the buffer block 74 to tend to move away from the baffle 72.

[0057] The spring compression device includes a sleeve 75, a connecting column 76, and a second spring 77. The sleeve 75 is fixedly connected to the road panel support frame 6. One end of the connecting column 76 is slidably inserted into the sleeve 75. The other end of the connecting column 76 is fixedly connected to the buffer frame. The buffer block 74 is rotatably connected to the buffer frame. The second spring 77 is arranged in the sleeve 75 to provide support for the connecting column 76. A guide rod 78 is provided at one end of the connecting column 76 located in the sleeve 75. The guide rod 78 passes through the sleeve 75 along the length of the connecting column 76 and extends outside the sleeve 75. The guide rod 78 is slidably engaged with the sleeve 75. A stop protrusion is provided at one end of the guide rod 78 located in the sleeve 75. In a specific embodiment, the guide rod 78 is a bolt. One end of the bolt is threadedly connected to the connecting column 76. The nut end of the bolt is located outside the sleeve 75 to form a stop protrusion.

[0058] The foldable road panel 1 located on the road panel support frame 6 contacts the buffer block 74 during the unfolding process, pushing the buffer block 74 away, thereby compressing the second spring 77. When a folded road panel unfolds after overcoming the damping of the spring compression device, the second spring 77 recovers, thereby pushing the buffer block 74 to reset, so as to decelerate the next folded road panel.

[0059] Reference Figure 2 In a specific embodiment, a lifting hoisting mechanism 9 is provided on the road panel carrier 5. The lifting hoisting mechanism 9 includes a hoist, a cable provided on the hoist, and a pulley provided on the road panel carrier 5. The cable is connected to the road panel via a shackle. The road panel can be moved from a horizontal position to a vertical position by hoisting the hoisting mechanism. In another specific embodiment, the lifting hoisting mechanism 9 can be replaced by a solution of installing a boom 10 on a vehicle frame, so as to realize the transportation and laying of the road panel without the need for additional auxiliary lifting equipment. Figure 7 As shown, the boom 10 comprises a boom turntable 101, a telescopic boom 102, and a hook 103. The hook 103 is located at the end of the telescopic boom 102, which is mounted on the boom turntable 101, which is mounted on the vehicle frame. The telescopic boom 102 has a built-in lifting rope that, in conjunction with a winch mechanism, enables the hook 103 to move up and down. The boom turntable 101 has a built-in hydraulic cylinder that allows the boom 100 to swing slightly left and right. This allows the road panel to be fine-tuned during hoisting, ensuring a stable placement on the road panel support frame 6.

[0060] Reference Figure 8 The panel transport vehicle 3 includes a panel carrier 32, a lifting device, and a swing arm 31. The panel carrier 32 is provided with a walking system. The lifting device is provided on the panel carrier 32. The lifting device includes a lifting seat and a driving member for driving the lifting seat to rise and fall. The swing arm 31 is provided on the lifting seat. A laying frame 33 is suspended on the swing arm 31. A suction cup 34 for adsorbing the panel 4 is provided on the side of the laying frame 33 close to the bottom surface. The panel carrier 32 can drive the swing arm 31 to move. In a specific embodiment, the panel carrier 32 is a forklift, and the lifting device and the swing arm 31 are provided by the forklift. In actual use, a plurality of suction cups 34 are provided at the bottom end of the laying frame 33 of the panel transport vehicle 3. The number of suction cups 34 is set according to the size and dimensions of the transported panel 4. The laying frame 33 sucks the panel 4 through the suction cups 34, adjusts the left and right position through the swing arm 31, and adjusts the up and down position through the lifting device, and places it in the designated position.

[0061] Reference Figure 9-12 The workflow of the rapid laying system for the foldable road panel 1 in this embodiment is as follows:

[0062] First, mark the laying positions of the road panels 1 and panels 4 at the designated positions of the road panels to be laid; then, the panel paving vehicle 3 sucks a panel 4 with the suction cup 34 and drives it to the area to be laid, adjusts the left and right positions by the swing arm 31, and adjusts the up and down positions by the lifting device, and places it at the position of the first panel 4 marked on the ground, anchors the panel 4 to the ground through its first row of holes, and repeats the above operation until all panels 4 are laid; then, the road panel paving vehicle 2 unfolds the right frame 63, the left frame 62, and the fork plate 64, and lifts the road surface The panel support frame 6 and the fork plate 64 of the panel support frame 6 remove the foldable panel 1 from storage and transport it to the area to be laid. The cable of the hoisting winch mechanism 9, via rollers 88, lifts the panel from a horizontal position to a vertical position. The first folded panel is then lowered. The two end clamping assemblies 7 control the panel's linear left and right movement. The forklift's own rotating sliding frame controls the center frame 61 to swing up and down, forward and backward, and horizontally, fine-tuning the panel's position so that it is flush with the marked starting position and the holes in the panel are aligned with the holes in the panel 4. After placement, the first folded panel is secured to the ground. After securing, the panel laying vehicle 2 retreats with the remaining panels. The elastic clamping assemblies 8 on the panel laying vehicle 2 ensure that the panels fall one by one, keeping the remaining panels tightly together. After each fold is laid, the panel is promptly secured to the panel 4 to prevent subsequent panel laying processes from affecting its positioning. The panel laying vehicle 2 transports and lays the panels according to the needs of the laying process until the paving is complete.
