Description

Technical Field

[0001] The invention relates to the technical field of polyethylene paving slab transportation, in particular to a material transportation device for highway engineering construction. Background Art

[0002] Polyethylene paving slabs are a type of plastic paving material made from polyethylene as the main raw material. They are lightweight, corrosion-resistant, and resistant to UV radiation. They usually use double-layer or multi-layer composite technology to enhance overall strength and wear resistance.

[0003] During highway construction, stacks of paving slabs are typically transported to the construction site by transport vehicles. When paving slabs need to be laid, they are moved to the appropriate location using manual handling or lifting equipment. Workers then make small adjustments to the paving slabs being transferred to the roadbed to ensure alignment with adjacent paving slabs, completing the paving slab installation.

[0004] In the existing technology, although polyethylene paving slabs are characterized by light weight, they are generally large in size, so they are still heavy. Manual transportation is laborious and inefficient. Lifting and moving them with lifting equipment requires bundling the paving slabs first, and then untying them when they are lifted to the required position, which is also time-consuming, resulting in low efficiency in the transportation of paving slabs. Therefore, there is an urgent need for a material transfer device for highway engineering construction. Summary of the Invention

[0005] The purpose of the present invention is to provide a material transfer device for highway engineering construction to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a material transfer device for highway engineering construction, comprising: a base plate; a first conveyor belt fixedly mounted on the top of the base plate; a transfer assembly connected to the top of the base plate; a discharge assembly and a material delivery assembly further connected to the top of the base plate, the discharge assembly and the material delivery assembly being located on the left and right sides of the transfer assembly, respectively;

[0007] The transfer assembly is used to intermittently transport the stacked paving slabs one by one from bottom to top to the top surface of the first conveyor belt;

[0008] The unloading assembly is used to deliver the paving slabs conveyed by the first conveyor belt to the roadbed;

[0009] The material delivery component is used to deliver the spare stacked paving slabs to the transfer component.

[0010] Preferably, the transfer assembly includes a shifting mechanism connected to the top of the bottom plate, the shifting mechanism is symmetrically connected to two limit clamps in the front and back, the bottoms of the two limit clamps are symmetrically connected to two first clamping plates, the shifting mechanism drives the two limit clamps to rise and fall and move toward each other, the bottoms of the two limit clamps are also symmetrically connected to two second clamping plates, the two second clamping plates are respectively located directly below the two first clamping plates, the transfer assembly also includes two transmission mechanisms symmetrically connected to the sides away from the two limit clamps in the front and back, the two first clamping plates The plate and the two second clamping plates are symmetrically connected to the two transmission mechanisms. The transfer assembly also includes a driving mechanism connected to the limiting clamping plate. The driving mechanism is connected to the two transmission mechanisms. The driving mechanism drives the two first clamping plates and the two second clamping plates to alternately clamp the paving slabs through the two transmission mechanisms. The advantage of this arrangement is that the two limiting clamping plates can move toward each other through the shifting mechanism so that the limiting clamping plates can clamp paving slabs of different widths. The shifting mechanism drives the two limiting clamping plates to move up and down so that a stack of paving slabs clamped by the limiting clamping plates is located on the upper side of the second conveyor belt. In this way, the two limiting clamps can clamp the paving slabs transferred by the second conveyor belt. When the second conveyor belt moves away from the first conveyor belt under the drive of the left and right moving mechanism, the limiting clamps can be driven to move downward close to the top surface of the first conveyor belt so as to smoothly deliver the lowermost paving slab to the top surface of the first conveyor belt, ensuring that the transfer work is carried out smoothly and reliably. At the same time, the driving mechanism drives the two first clamping plates and the two second clamping plates to alternately clamp the paving slabs. When the two second clamping plates move away from each other, the two first clamping plates move closer to each other, so that the two first clamping plates will be located between them. The paving slab between the two second clamping plates is clamped, while the paving slab between the two second clamping plates is released and falls downward to the top surface of the first conveyor belt, and then the driving mechanism drives the first clamping plate and the second clamping plate to move in opposite directions, so that the stack of paving slabs located above the second clamping plates falls downward, and the lowermost paving slab is clamped when it is located between the two second clamping plates. This cycle can be repeated to intermittently transfer a stack of paving slabs from bottom to top one by one to the top surface of the first conveyor belt, ensuring that the automatic transfer of the paving slabs is carried out smoothly and reliably, thereby improving the reliability of the transfer device.

[0011] Preferably, the transmission mechanism includes two connecting plates symmetrically connected to the bottom of the limit clamping plate, and the first clamping plate and the second clamping plate on the same side are symmetrically rotated and connected to the sides of the two connecting plates away from each other through the first rotating rod and the first torsion spring. The two connecting plates are connected to the driving mechanism, and the driving mechanism is used to drive the two connecting plates to intermittently move in opposite directions. The advantage of such an arrangement is that the two first clamping plates and the two second clamping plates can fully and completely fit tightly against the side surfaces of the paving slab when clamping the paving slab, thereby ensuring the clamping stability of the paving slab.

[0012] Preferably, the transmission mechanism also includes two fixed plates symmetrically fixedly connected to the side of the limit clamp away from the first conveyor belt, and the first rotating shaft is rotatably connected between the adjacent sides of the two fixed plates, and a roller is fixedly sleeved on the outer circumference of the first rotating shaft, and the sides of the two connecting plates on the same side away from the first clamping plate and the second clamping plate are fixedly connected to the outer circumference of the roller, and the driving mechanism drives the first rotating shaft to swing back and forth clockwise or counterclockwise, The advantage of such an arrangement is that it is only necessary to drive the first rotating shaft and the roller to swing back and forth clockwise or counterclockwise by the driving mechanism, and then cooperate with the first rotating rod and the first torsion spring to drive the two first clamping plates and the two second clamping plates to clamp the paving slabs quickly and alternately, thereby simplifying the structural complexity of the transmission mechanism and improving the practicality of the transfer device.

[0013] Preferably, the driving mechanism includes two pairs of cylinders symmetrically fixedly connected to the side surfaces away from each other of the two pairs of fixed plates, and two pairs of racks are symmetrically fixedly connected to the output ends of the two pairs of cylinders. The left and right ends of the two first rotating shafts respectively pass through the two pairs of fixed plates and are symmetrically fixedly sleeved with two pairs of gears, and the two pairs of gears are respectively engaged with the two pairs of racks. The advantage of such an arrangement is that the racks are driven by the cylinders to move back and forth quickly, thereby driving the gears and the first rotating shafts to rotate back and forth quickly clockwise or counterclockwise, thereby ensuring that the transfer component will only transfer the lowest paving slab to the top surface of the first conveyor belt each time, thereby ensuring that the transfer of the paving slabs is carried out smoothly and orderly, further improving the reliability of the transfer device.

[0014] Preferably, the shift mechanism includes two pairs of first hydraulic cylinders symmetrically fixedly connected to the top of the base plate, two lifting plates symmetrically fixedly connected between the output ends of the two pairs of the first hydraulic cylinders, two pairs of second hydraulic cylinders symmetrically fixedly connected to the tops of the two lifting plates, and the two side surfaces of the two limiting splints that are away from each other are symmetrically fixedly connected between the output ends of the two pairs of second hydraulic cylinders. The advantage of such an arrangement is that the two limiting splints can be driven to move up and down to move away from or close to the top surface of the first conveyor belt through the extension and contraction of the first hydraulic cylinder, and the two limiting splints are pushed closer to or away from each other by the two teams of second hydraulic cylinders, so that the two limiting splints can reliably limit paving slabs of different sizes, thereby expanding the transfer range of the transfer device and improving the practicality of the transfer device.

[0015] Preferably, the unloading assembly includes two vertical plates symmetrically fixedly connected to the top of the bottom plate by a fixed block, the two vertical plates are symmetrically connected to the two second rotating shafts on the side surfaces close to each other, a guide plate is fixedly connected between the ends close to the two second rotating shafts, the front of the vertical plate located on the front side is fixedly connected to the first motor, the front end of the second rotating shaft located on the front side passes through the front vertical plate and is fixedly connected to the output end of the first motor, the top of the guide plate is equidistantly connected to a plurality of unpowered rollers that rotate equidistantly from left to right, the tops of the plurality of unpowered rollers are flush with the top surface of the first conveyor belt, a baffle is fixedly connected between the left ends of the two vertical plates, two collision sensors are symmetrically fixedly connected to the right side surface of the baffle, the two collision sensors are electrically connected to the first motor, the left end of the vertical plate and the guide plate The left end of each is located on the left side of the left side of the bottom plate. The advantage of this arrangement is that when the first conveyor belt transports a paving slab to the left to the top of the unpowered roller, the paving slab will slide to the left along the top of the unpowered roller until it collides with the pressure collision sensor. After receiving the collision signal, the collision sensor will transmit the signal to the control computer, and then the control computer will start the first motor to drive the second shaft to rotate counterclockwise. The second shaft drives the guide plate, the unpowered roller and the paving slab to rotate counterclockwise, so that the paving slab can be transported to the roadbed at an angle, and the obstruction of the collision sensor can stop the paving slab from moving to the left. Then the guide plate rotates counterclockwise to drive the paving slab to slide slowly downward, thereby preventing the paving slab from falling directly from a high place to the roadbed, protecting the safety of the paving slab and improving the reliability of the transfer device.

[0016] Preferably, the material delivery assembly includes a left and right moving mechanism connected to the top of the bottom plate, the left and right moving mechanism is connected to a support block, the top of the support block is fixedly connected to a support plate, and a second conveyor belt is installed on the top of the support plate, and the left and right moving mechanism is used to drive the support block to move left and right, and the bottom surface of the support plate is located on the upper side of the top surface of the first conveyor belt. The advantage of this arrangement is that the support block is driven to move left by the left and right moving mechanism, and the support block drives the second conveyor belt to move left to the upper side of the first conveyor belt through the support plate, so that the spare paving slabs stacked on the top surface of the second conveyor belt can be located on the upper side of the first conveyor belt, and at this time the two limit clamps The slab is pushed by the first hydraulic cylinder and is located above the second conveyor belt. Then the second hydraulic cylinder pushes the two limit clamps to fit the front and rear sides of the spare paving slab. Then the driving mechanism drives the two second clamping plates closer to each other until the lowermost paving slab is clamped. After that, the left and right moving mechanism drives the second conveyor belt away from the first conveyor belt, and the first hydraulic cylinder is started to drive the second clamping plate to move downward close to the top surface of the first conveyor belt. In this way, the transfer of the spare paving slab is completed. In this way, multiple stacks of paving slabs can be placed on the top surface of the second conveyor belt at one time, thereby reducing the frequency of transporting the paving slabs toward the transfer device, thereby effectively improving the efficiency of paving slab transfer.

[0017] Preferably, an auxiliary blanking assembly is connected to the bottom of the baffle, which is used to slow down the speed at which the paving slab slides down from the guide plate. The advantage of this arrangement is that it can prevent the paving slab from falling quickly onto the roadbed and being damaged, thereby improving the reliability of the transfer device.

[0018] Preferably, the auxiliary blanking assembly includes an inclined plate fixedly connected to the bottom of the baffle, and two insertion rods are symmetrically and movably inserted on the side of the inclined plate away from the baffle, and a blocking plate is fixedly connected between the ends of the two insertion rods away from the inclined plate, and the blocking plate and the inclined plate are perpendicular, and two elastic members are symmetrically and fixedly connected between the sides of the blocking plate and the inclined plate close to each other. The advantage of this arrangement is that when the paving plate slides downward along the unpowered roller and the guide plate, it will collide with the right side of the blocking plate, and then the paving plate will overcome the elastic force of the elastic member under the action of its own gravity and push the blocking plate to move to the lower left. When the moving distance of the paving plate is large, the left end of the paving plate will rotate downward and disengage from the blocking plate to fall smoothly on the roadbed, which can further reduce the speed of the paving plate sliding toward the roadbed and further prevent the paving plate from being damaged when it slides.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention can transport the stacked paving slabs from bottom to top one by one intermittently to the top surface of the first conveyor belt through the transfer component, and then the first conveyor belt transports the paving slabs to the left to the unloading component, and then the unloading component transports the paving slabs to the roadbed. In this way, the paving slabs can be automatically transferred to the roadbed in an intermittent and orderly manner, without the need for staff to laboriously carry them one by one or to time-consumingly lift them one by one through lifting equipment, effectively improving the transfer speed of the paving slabs. At the same time, the spare paving slabs can be automatically transferred to the transfer component through the delivery component, so that multiple stacks of paving slabs can be placed on the top surface of the second conveyor belt at one time, thereby reducing the frequency of transporting the paving slabs toward the transfer device, which can further improve the efficiency of paving slab transfer.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1-8 The material transfer device for highway engineering construction shown in the figure includes: a base plate 1; a first conveyor belt 2 is fixedly installed on the top of the base plate 1, a transfer assembly 3 is connected to the top of the base plate 1, and a discharge assembly 4 and a material delivery assembly 5 are also connected to the top of the base plate 1. The discharge assembly 4 and the material delivery assembly 5 are respectively located on the left and right sides of the transfer assembly 3;

[0032] The transfer assembly 3 is used to intermittently transport the stacked paving slabs one by one from bottom to top to the top surface of the first conveyor belt 2;

[0033] The unloading assembly 4 is used to deliver the paving slabs conveyed by the first conveyor belt 2 to the roadbed;

[0034] The material delivery component 5 is used to deliver the spare stacked paving slabs to the transfer component 3.

[0035] See Figures 1-6 The transfer assembly 3 includes a shifting mechanism 31 connected to the top of the base plate 1, and two limit clamping plates 32 are symmetrically connected to the shifting mechanism 31 front and back. The bottom of the two limit clamping plates 32 is symmetrically connected to two first clamping plates 33. The shifting mechanism 31 drives the two limit clamping plates 32 to rise and fall and move toward each other. The bottom of the two limit clamping plates 32 is also symmetrically connected to two second clamping plates 34. The two second clamping plates 34 are respectively located directly below the two first clamping plates 33. The transfer assembly 3 also includes two transmission mechanisms 35 symmetrically connected to the sides away from the two limit clamping plates 32 front and back. The two first clamping plates 33 and the two second clamping plates 34 are symmetrically connected to the two transmission mechanisms 35. The transfer assembly 3 also includes a driving mechanism 36 connected to the limit clamping plates 32, and the driving mechanism 36 is connected to the two transmission mechanisms 35. The driving mechanism 36 drives the two first clamping plates 33 and the two second clamping plates 34 to alternately clamp the paving slab through the two transmission mechanisms 35.

[0036] Specifically, the two limiting clamps 32 can move toward each other through the shifting mechanism 31, so that the limiting clamps 32 can clamp paving slabs of different widths. The shifting mechanism 31 drives the two limiting clamps 32 to move up and down, so that a stack of paving slabs clamped by the limiting clamps 32 can be located on the upper side of the second conveyor belt 54, so that it is convenient for the two limiting clamps 32 to clamp the paving slabs transferred from the second conveyor belt 54. When the second conveyor belt 54 moves away from the first conveyor belt 2 under the drive of the left and right moving mechanism 51, the limiting clamps 32 can be driven to move downward close to the top surface of the first conveyor belt 2 so as to smoothly deliver the lowermost paving slab to the top surface of the first conveyor belt 2, ensuring that the transfer work is carried out smoothly and reliably. At the same time, the driving mechanism 36 drives the two first clamping plates 33 and the two second clamping plates 34 to clamp alternately. Paving slabs, when the two second clamping plates 34 move away from each other, the two first clamping plates 33 move closer to each other, so that the two first clamping plates 33 clamp the paving slab located in the middle, and the paving slab located between the two second clamping plates 34 is released and falls downward to the top surface of the first conveyor belt 2, and then the driving mechanism 36 drives the first clamping plates 33 and the second clamping plates 34 to move in opposite directions, so that a stack of paving slabs located on the upper side of the second clamping plates 34 falls downward, and the paving slab on the lowermost side is clamped when it is located between the two second clamping plates 34. This cycle can be repeated to intermittently transfer a stack of paving slabs from bottom to top one by one to the top surface of the first conveyor belt 2, ensuring that the automatic transfer of the paving slabs is carried out smoothly and reliably, thereby improving the reliability of the transfer device.

[0037] See Figure 5 and Figure 6The transmission mechanism 35 includes two connecting plates 351 symmetrically connected to the bottom of the limiting clamp 32. The first clamping plate 33 and the second clamping plate 34 on the same side are symmetrically rotated and connected to the sides away from each other of the two connecting plates 351 through the first rotating rod and the first torsion spring. The two connecting plates 351 are connected to the driving mechanism 36, which is used to drive the two connecting plates 351 to intermittently move in the opposite direction.

[0038] Specifically, the two first clamping plates 33 and the two second clamping plates 34 can fully and completely fit tightly against the side surfaces of the paving slab when clamping the paving slab, thereby ensuring the clamping stability of the paving slab.

[0039] See Figure 2 、 Figure 3 、 Figure 5 and Figure 8 The transmission mechanism 35 also includes two fixed plates 352 symmetrically fixedly connected to the side of the limiting clamping plate 32 away from the first conveyor belt 2. A first rotating shaft 353 is rotatably connected between the adjacent sides of the two fixed plates 352. A roller 354 is fixedly sleeved on the outer circumference of the first rotating shaft 353. The sides of the two connecting plates 351 on the same side away from the first clamping plate 33 and the second clamping plate 34 are fixedly connected to the outer circumference of the roller 354. The driving mechanism 36 drives the first rotating shaft 353 to swing back and forth clockwise or counterclockwise.

[0040] Specifically, the driving mechanism 36 only needs to drive the first rotating shaft 353 and the rotating roller 354 to swing back and forth clockwise or counterclockwise, and then cooperate with the first rotating rod and the first torsion spring to drive the two first clamping plates 33 and the two second clamping plates 34 to clamp the paving slabs alternately and quickly, thereby simplifying the structural complexity of the transmission mechanism 35 and improving the practicality of the transfer device.

[0041] See Figure 8 The driving mechanism 36 includes two pairs of cylinders 361 symmetrically fixedly connected to the sides away from each other of the two pairs of fixed plates 352. Two pairs of racks 362 are symmetrically fixedly connected to the output ends of the two pairs of cylinders 361. The left and right ends of the two first rotating shafts 353 respectively pass through the two pairs of fixed plates 352 and are symmetrically fixedly sleeved with two pairs of gears 363. The two pairs of gears 363 are respectively engaged with the two pairs of racks 362.

[0042] Specifically, the cylinder 361 drives the rack 362 to move back and forth quickly up and down, which can drive the gear 363 and the first rotating shaft 353 to rotate back and forth quickly clockwise or counterclockwise, thereby ensuring that the transfer component 3 will only transfer the lowest paving slab to the top surface of the first conveyor belt 2 each time, thereby ensuring that the transfer of the paving slabs is carried out smoothly and orderly, further improving the reliability of the transfer device.

[0043] See Figure 1 and- Figure 4 The shifting mechanism 31 includes two pairs of first hydraulic cylinders 311 symmetrically fixedly connected to the top of the base plate 1, two lifting plates 312 are symmetrically fixedly connected between the output ends of the two pairs of first hydraulic cylinders 311, two pairs of second hydraulic cylinders 313 are symmetrically fixedly connected to the tops of the two lifting plates 312, and the sides away from each other of the two limiting clamps 32 are symmetrically fixedly connected between the output ends of the two pairs of second hydraulic cylinders 313.

[0044] Specifically, the extension and retraction of the first hydraulic cylinder 311 can drive the two limiting clamps 32 to move up and down to move away from or close to the top surface of the first conveyor belt 2, and the two teams of second hydraulic cylinders 313 push the two limiting clamps 32 to move closer to or away from each other, so that the two limiting clamps 32 can reliably limit paving slabs of different sizes, thereby expanding the transfer range of the transfer device and improving the practicality of the transfer device.

[0045] See Figure 1-Figure 4 The unloading assembly 4 includes two vertical plates 41 symmetrically fixed to the top of the base plate 1 through a fixed block, and the adjacent sides of the two vertical plates 41 are symmetrically connected to two second rotating shafts, and a guide plate 42 is fixedly connected between the adjacent ends of the two second rotating shafts. The front side of the vertical plate 41 on the front side is fixedly connected to a first motor 43, and the front end of the second rotating shaft on the front side passes through the front vertical plate 41 and is fixedly connected to the output end of the first motor 43. The top of the guide plate 42 is equidistantly connected to multiple unpowered rollers 44 for rotation from left to right, and the tops of the multiple unpowered rollers 44 are all flush with the top surface of the first conveyor belt 2. A baffle 45 is fixedly connected between the left ends of the two vertical plates 41, and two collision sensors 46 are symmetrically fixedly connected to the right side of the baffle 45. The two collision sensors 46 are electrically connected to the first motor 43. The left end of the vertical plate 41 and the left end of the guide plate 42 are both located on the left side of the left side of the base plate 1.

[0046] Specifically, when the first conveyor belt 2 conveys a paving slab to the left to the top of the unpowered roller 44, the paving slab will slide to the left along the top of the unpowered roller 44 until it collides with the pressure collision sensor 46. After receiving the collision signal, the collision sensor 46 will transmit the signal to the control computer, and then the control computer will start the first motor 43 to drive the second shaft to rotate counterclockwise. The second shaft drives the guide plate 42, the unpowered roller 44 and the paving slab to rotate counterclockwise, so that the paving slab can be conveyed to the roadbed at an angle, and the obstruction of the collision sensor 46 can stop the paving slab from moving to the left. Then the guide plate 42 rotates counterclockwise to drive the paving slab to slide slowly and obliquely downward, thereby preventing the paving slab from falling directly from a high place to the roadbed, protecting the safety of the paving slab and improving the reliability of the transfer device.

[0047] See Figure 1-Figure 4The material delivery assembly 5 includes a left-right moving mechanism 51 connected to the top of the base plate 1, a support block 52 is connected to the left-right moving mechanism 51, a support plate 53 is fixedly connected to the top of the support block 52, and a second conveyor belt 54 is installed on the top of the support plate 53. The left-right moving mechanism 51 is used to drive the support block 52 to move left and right, and the bottom surface of the support plate 53 is located on the upper side of the top surface of the first conveyor belt 2.

[0048] Specifically, the left-right moving mechanism 51 drives the support block 52 to move left, and the support block 52 drives the second conveyor belt 54 to move left to the upper side of the first conveyor belt 2 through the support plate 53, so that the spare paving slabs stacked on the top surface of the second conveyor belt 54 can be located on the upper side of the first conveyor belt 2, and at this time, the two limiting clamping plates 32 are located above the second conveyor belt 54 under the push of the first hydraulic cylinder 311, and then the second hydraulic cylinder 313 pushes the two limiting clamping plates 32 to fit the front and rear sides of the spare paving slabs, and then the driving mechanism 36 drives the two second clamping plates 34 to move closer to each other until the lowermost paving slab is clamped. Subsequently, after the left-right moving mechanism 51 drives the second conveyor belt 54 away from the first conveyor belt 2, the first hydraulic cylinder 311 is started to drive the second clamping plates 34 to move downward close to the top surface of the first conveyor belt 2, so that the transfer of the spare paving slabs is completed. In this way, multiple stacks of paving slabs can be placed on the top surface of the second conveyor belt 54 at one time, thereby reducing the frequency of transporting the paving slabs toward the transfer device, thereby effectively improving the efficiency of paving slab transfer.

[0049] See Figure 3 and Figure 7 The bottom of the baffle 45 is connected to an auxiliary blanking assembly 6, which is used to slow down the speed at which the paving slab slides down from the guide plate 42.

[0050] Specifically, it can prevent the paving slab from falling quickly onto the roadbed and being damaged, thereby improving the reliability of the transfer device.

[0051] See Figure 3 and Figure 7 The auxiliary blanking assembly 6 includes an inclined plate 61 fixedly connected to the bottom of the baffle 45. Two insertion rods 62 are symmetrically and movably inserted on the side of the inclined plate 61 away from the baffle 45. A blocking plate 63 is fixedly connected between the ends of the two insertion rods 62 away from the inclined plate 61. The blocking plate 63 and the inclined plate 61 are perpendicular to each other. Two elastic members 64 are symmetrically and fixedly connected between the blocking plate 63 and the side close to the inclined plate 61.

[0052] Specifically, when the paving slab slides down along the unpowered roller 44 and the guide plate 42, it will collide with the right side of the blocking plate 63. Then, under the action of its own gravity, the paving slab will overcome the elastic force of the elastic member 64 and push the blocking plate 63 to move toward the lower left. When the blocking plate 63 moves a large distance, the left end of the paving slab will rotate downward and separate from the blocking plate 63 to fall smoothly on the roadbed. This can further reduce the speed at which the paving slab slides toward the roadbed, further preventing the paving slab from being damaged when it slides.

[0053] Working principle: First, the bottom plate 1 is fixedly installed on the flatbed of the flatbed truck, so that the transfer device can be installed on the truck, and at the same time, the left end of the vertical plate 41 and the left end of the guide plate 42 are located on the rear side of the truck flatbed. Then, multiple stacks of paving slabs are hoisted or transported from left to right to the top surface of the second conveyor belt 54, and then the staff removes the external packaging of the multiple stacks of paving slabs.

[0054] Then, the first hydraulic cylinder 311 is started to push the limiting clamping plate 32, the first clamping plate 33 and the second clamping plate 34 upward until the bottom surface of the second clamping plate 34 is located on the upper side of the top surface of the second conveyor belt 54, and then the left and right moving mechanism 51 is started to drive the support block 52 to move to the left, and the support block 52 drives the second conveyor belt 54 to move to the left to the upper side of the first conveyor belt 2 through the support plate 53, so that the spare paving slabs stacked on the top surface of the second conveyor belt 54 can be located on the upper side of the first conveyor belt 2.

[0055] Then, the second hydraulic cylinder 313 is started to push the two limiting clamps 32 to fit the front and rear sides of the spare paving slab, and then the two second clamping plates 34 are driven to move closer to each other through the driving mechanism 36 until the lowermost paving slab is clamped. Then, after the left and right moving mechanism 51 drives the second conveyor belt 54 away from the first conveyor belt 2, the first hydraulic cylinder 311 is started to drive the second clamping plate 34 to move downward close to the top surface of the first conveyor belt 2, so that the transfer of the spare paving slab is completed. In this way, multiple stacks of paving slabs can be placed on the top surface of the second conveyor belt 54 at one time, thereby reducing the frequency of transporting the paving slabs toward the transfer device, thereby effectively improving the efficiency of paving slab transfer.

[0056] Then, the cylinder 361 is activated to drive the rack 362 to move up and down quickly, which can drive the gear 363 and the first rotating shaft 353 to rotate back and forth quickly clockwise or counterclockwise, thereby driving the two first clamping plates 33 and the two second clamping plates 34 to alternately clamp the paving slabs. When the two second clamping plates 34 move away from each other, the two first clamping plates 33 move closer to each other, so that the two first clamping plates 33 clamp the paving slab located between them, and the paving slab located between the two second clamping plates 34 is released and It falls downward to the top surface of the first conveyor belt 2, and then the driving mechanism 36 drives the first clamping plate 33 and the second clamping plate 34 to move in the opposite direction, so that the pile of paving slabs located on the upper side of the second clamping plate 34 falls downward, and the paving slab on the lowermost side is clamped when it is located between the two second clamping plates 34. This cycle can be repeated to intermittently transfer a pile of paving slabs from bottom to top one by one to the top surface of the first conveyor belt 2, ensuring that the automatic transfer of the paving slabs is carried out smoothly and reliably, thereby improving the reliability of the transfer device.

[0057] Then the first conveyor belt 2 is started to transport the paving slab that falls on its top surface to the left to the top of the guide plate 42 and the unpowered roller 44, and then the paving slab will slide to the left along the top of the unpowered roller 44 until it collides with the pressure collision sensor 46. After receiving the collision signal, the collision sensor 46 will transmit the signal to the control computer, and then the control computer will start the first motor 43 to drive the second shaft to rotate counterclockwise. The second shaft drives the guide plate 42, the unpowered roller 44 and the paving slab to rotate counterclockwise, so that the paving slab can be transported to the roadbed at an angle, and the obstruction of the collision sensor 46 can stop the paving slab from moving to the left, and then the guide plate 42 rotates counterclockwise to drive the paving slab to slide slowly and obliquely downward, thereby preventing the paving slab from falling directly from a high place to the roadbed, protecting the safety of the paving slab and improving the reliability of the transfer device.

[0058] And when the paving slab slides downward to the lower left along with the guide plate 42, it will collide with the right side of the blocking plate 63. Then, under the action of its own gravity, the paving slab will overcome the elastic force of the elastic member 64 and push the blocking plate 63 to move toward the lower left. When the blocking plate 63 moves a large distance, the left end of the paving slab will rotate downward and separate from the blocking plate 63 to fall smoothly on the roadbed. This can further reduce the speed at which the paving slab slides toward the roadbed, further preventing the paving slab from being damaged when it slides.

[0059] The transfer device is then driven by a truck to move at a constant speed along the highway construction route, so that each paving slab can be transferred to the roadbed one by one in an orderly manner along the highway construction route.
