Description

Technical Field

[0001] This invention relates to the field of PC precast component transportation technology, specifically to a PC precast component transportation device with good stability. Background Technology

[0002] PC is the abbreviation for precast concrete components. In the field of residential industrialization, it is called PC components, such as precast reinforced concrete column foundations, precast steel structure column foundations, reinforced concrete foundations for streetlights and billboards, and precast floor slabs. In contrast, traditional cast-in-place concrete requires on-site molding, pouring, and curing. Precast concrete components are widely used in construction, transportation, water conservancy, and other fields, playing an important role in the national economy. However, traditional PC precast components are transported using flatbed trucks, which are directly fixed on the trucks for transport. This method of transportation is outdated, has low efficiency, and makes short-distance transport at construction sites difficult after long-distance transport. Therefore, it is necessary to study a PC precast component transportation device with good stability, suitable for both long-distance and short-distance transportation.

[0003] The shortcomings of existing methods for transporting precast PC components are:

[0004] 1. Patent document CN112692976A discloses a steam curing and transportation device for prefabricated small components for highway assembly. It "includes a transportation component and a steam curing component. The steam curing component includes a steam curing box, which contains a circulating steam curing platform and a steam pipe component. The steam pipe component includes a bottom steam curing pipe and an outer steam curing pipe. The output end of the bottom steam curing pipe faces the bottom surface of the prefabricated component, and the output end of the outer steam curing pipe faces the remaining surfaces of the prefabricated component. The circulating steam curing platform has a steam curing cavity inside, and several circulating support cylinders are arranged side-by-side within the steam curing cavity. The output end of the circulating support cylinders is connected to a circulating support plate. The upper surface of the circulating steam curing platform has steam curing notches. Through the circulating support and circulating steam curing of the prefabricated component, the ground surface of the prefabricated component is steam cured over the entire area, thereby achieving the purpose of steam curing all surfaces of the prefabricated component, eliminating steam curing dead zones, improving steam curing effect and efficiency, and reducing the energy consumption required for steam curing." However, its transportation device has poor stability. During transportation, the frame of the prefabricated component is prone to loosening with the flatbed truck, posing a safety hazard.

[0005] 2. Patent document CN210793986U discloses a precast component transportation device, "including a flatbed truck and a stacked storage rack. The stacked storage rack includes a column assembly and a crossbeam. The column assembly includes a first column, a second column, and a limiting plate. The top of the first column is connected to the bottom of the second column. The bottom of the first column is provided with a longitudinal groove that matches the size of the second column. The upper part of the second column is provided with the limiting plate. The four column assemblies are arranged in a rectangular shape. The first columns of two adjacent column assemblies are connected by the crossbeam. The flatbed truck includes a platform. The bottom of the platform is provided with several wheels. The top surface of the platform is provided with a stacked storage rack receiving groove that matches the size of the stacked storage rack. This device improves the short-distance transportation efficiency of precast components. Several stacked storage racks can be used individually for storing precast components, making full use of vertical space. The storage is organized, loading and unloading are convenient, and the cleanliness of the factory is improved." However, the stability of the transported components is relatively troublesome.

[0006] 3. Patent document CN213535662U discloses a transportation protection device for precast concrete components, "including a base plate, with first circular grooves at both ends of the outer walls on both sides of the base plate, and spring telescopic rods fixedly connected to the bottom inner walls of the four first circular grooves, and structural plates fixedly connected to the four spring telescopic rods respectively, with through holes in the middle outer walls of the two structural plates, and second circular grooves in the middle of both sides of the base plate, with adjusting mechanisms fixedly connected to the bottom inner walls of the two second circular grooves, the adjusting mechanism including a threaded rod, an internal threaded tube, and a fixing block. The shock-absorbing components on the base plate and the shock-absorbing rubber pads bonded to the support plate can reduce the bumps and vibrations encountered by the precast components during transportation. The structural plates on both sides of the base plate can fix the precast components to the protection device through the spring telescopic rods and the adjusting mechanism to prevent unstable shaking of the precast components during transportation." However, its transportation device is affected by the size of the precast components, and larger precast components cannot be placed.

[0007] 4. Patent document CN214604950U discloses a precast component vibration transport device, "including a vibration platform, a conveying platform inserted into the vibration platform, and a lifting mechanism for controlling the lifting and lowering of the conveying platform within the vibration platform; the vibration platform includes a base, a vibration platform disposed on the base, a vibrator disposed at the bottom of the vibration platform, and a shock-absorbing spring disposed between the base and the vibration platform for supporting the vibration platform. This utility model reduces the distance of the conveying platform's vertical movement by connecting the conveying platform and the vibration platform together and isolating them by a height difference, thereby reducing the time for device function switching, improving work efficiency, and preventing the conveying platform from vibrating along with the vibration platform, reducing frictional wear of the conveying platform, and extending the service life of the conveying platform." However, its transport device lacks a warning structure, making it prone to collisions during transport. Summary of the Invention

[0008] The purpose of this invention is to provide a PC precast component transportation device with good stability, so as to solve the problem of poor stability mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a PC precast component transportation device with good stability, comprising a transportation frame, a support plate and a fixing block, wherein the fixing block is installed on the outer wall of the transportation frame;

[0010] A movable plate is installed on the inner wall of the fixed block, and a movable block is installed on the outer wall of the movable plate. One end of the movable block extends out of the outer wall of the fixed block. A rotary knob is installed on the outer wall of the movable block. A screw is installed at the end of the rotary knob, and one end of the screw extends into the outer wall of the movable plate. A pentagonal block is installed on the top of the movable block, and a screw is installed at the bottom of the pentagonal block. A transmission plate is installed on the outer wall of the screw. A limiting plate is installed at the bottom of the movable block, and a top plate is installed on the outer wall of the limiting plate. The outer wall of the top plate is connected to the outer wall of the transmission plate.

[0011] Hydraulic rods are installed on the inner top wall of the transport frame.

[0012] Preferably, a connecting plate is installed at the bottom of the hydraulic rod, and rollers are installed at the bottom of the connecting plate.

[0013] Preferably, a cylinder is installed on the inner wall of the support plate, and a push block is installed at the output end of the cylinder.

[0014] Preferably, a telescopic rod is installed on the inner top wall of the support plate, a No. 1 spring is installed on the inner top wall of the support plate, a pressure plate is installed at the bottom of the telescopic rod, and an inclined block is installed at the top of the pressure plate.

[0015] Preferably, the fixing block is located on the bottom outer wall of the transport frame, and four sets of fixing blocks are evenly distributed on the outer wall of the rod of each set of transport frames. Four sets of notches are opened on one side of the transport frame, the limiting plate is provided with a sliding groove, the transmission plate and the top plate are connected through the sliding groove, the push block is located on one side of the inclined block, and one end of the No. 1 spring is connected to the top of the pressure plate.

[0016] Preferably, a support frame is installed on the inner bottom wall of the transport frame, a limiting rod is installed on the outer wall of the support frame, a second spring is installed at the bottom of the limiting rod, one end of the second spring is connected to the inner bottom wall of the transport frame, a fixing plate is installed on the outer wall of the transport frame, a first motor is installed on the outer wall of the fixing plate, a reel is installed at the output end of the first motor, a pull rope is installed on the outer wall of the reel, and one end of the pull rope is connected to the outer wall of the limiting rod.

[0017] Preferably, a second motor is installed on the inner top wall of the transport frame, a threaded rod is installed at the output end of the second motor, an internal threaded plate is installed on the outer wall of the threaded rod, and a locking block is installed at the bottom of the internal threaded plate.

[0018] Preferably, a support bar is installed on the top of the support plate, a connecting plate is installed on the inner wall of the support bar, a touch plate is installed on the top of the connecting plate, a contact point is installed on the bottom of the connecting plate, a button is installed on the inner wall of the support bar, a No. 3 spring is installed on the inner bottom wall of the support bar, and one end of the No. 3 spring is connected to the bottom of the connecting plate, and a warning light is installed on the outer wall of the transport frame.

[0019] Preferably, the operating steps of the transport device are as follows:

[0020] S1. When prefabricated components need to be transported remotely within the transport frame, the transport frame is transported to a flatbed truck via rollers. Subsequently, a hydraulic rod drives a connecting plate to move, which in turn drives the rollers to move, raising the rollers and bringing the transport frame into contact with the flatbed truck. At this point, the limiting plate is located on the outside of the flatbed truck body. Rotating the knob drives the first screw to rotate, which in turn drives the moving plate to move, which in turn drives the moving block to move. The moving block clamps the limiting plate on the outside of the flatbed truck body, and the top plate is located on the bottom side of the flatbed truck body. Then, the pentagonal block is rotated by the tightening device, which drives the second screw to rotate, which in turn drives the transmission plate to rotate, which in turn drives the top plate to move. This locks the transport frame onto the flatbed truck, clamping it in both directions, making the transport device fixed and stable, thus improving its stability.

[0021] S2. The precast component is placed on the top of the support plate of the transport frame. When the component is placed, the cylinder drives the push block to move. The push block moves and pushes the inclined block to move. The inclined block is squeezed downward, causing the pressure plate to move downward and press against the top of the precast component. This makes the loose precast component stable on the transport frame. When disassembling, the cylinder drives the push block to return to its original position, and the No. 1 spring pulls the pressure plate back to its original position. At this time, the pressure plate no longer presses against the precast component. This structure makes the fixing and disassembly of the precast component simple and convenient, and improves the installation speed.

[0022] S3. When the precast component is placed on the transport frame by the forklift, the No. 1 motor rotates, driving the reel to rotate. The rotating reel winds the pull rope, which pulls the limiting rod to rotate, causing the notch in the transport frame to open. At this time, the No. 2 spring is stretched. After placement, the No. 1 motor reverses, and the No. 2 spring restores the limiting rod. At this time, the limiting rod is located on the bottom side of the locking block. The No. 2 motor rotates, driving the threaded rod to rotate. The threaded rod engages with the threaded hole of the internal threaded plate. The rotation of the threaded rod drives the internal threaded plate to move, and the movement of the internal threaded plate drives the locking block to move. The locking block moves and embeds into the limiting rod, locking the limiting rod. The notch in this structure allows precast components with larger lengths to be placed into the transport frame, so that the placement of precast components is not restricted by the fixed rod of the transport frame. Moreover, after placement, the locking of the limiting rod is quick, preventing the precast component from slipping out.

[0023] S4. When the precast component is placed, the precast component touches the contact plate, so that the precast component is supported by the support bar. At this time, the contact point is pressed down and contacts the button, which makes the warning light light up, so that people around can notice that the transport rack is loaded with precast components. During transportation, the possibility of collision with other vehicles is reduced, and the warning effect is more obvious at night.

[0024] Preferably, step S1 further includes the following steps:

[0025] S11. When moving, the hydraulic rod drives the roller to move downward, so that the transport frame is supported by the roller. When stable, the hydraulic rod drives the roller to move upward, so that the bottom of the transport frame contacts the placement surface.

[0026] Step S3 further includes the following steps:

[0027] S31, most of the second spring is embedded inside the notch of the transport frame, and the limiting rod is movably connected to the support frame, so that the limiting rod can rotate on the support frame;

[0028] Step S4 further includes the following steps:

[0029] S41. Its warning lights are distributed around the transport frame. When the prefabricated component is removed, the No. 3 spring can restore the connecting plate, so that the contact point and the button are no longer in contact, and the warning light can be turned off.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. This invention, equipped with a fixing block, a limiting plate, and a top plate, places prefabricated components within a transport frame for long-distance transport. The transport frame is then transported to a flatbed truck via rollers. A hydraulic rod moves a connecting plate, which in turn moves the rollers, raising them and bringing the transport frame into contact with the flatbed truck. At this point, the limiting plate is located on the outside of the flatbed truck's body. Rotating a knob rotates a first screw, which in turn moves a moving plate, which in turn moves a moving block. The moving block clamps the limiting plate to the outside of the flatbed truck's body, with the top plate located at the bottom of the flatbed truck's body. Then, a tightening mechanism rotates a pentagonal block, which in turn rotates a second screw, which in turn rotates a transmission plate, which in turn moves the top plate. This locks the transport frame onto the flatbed truck with bidirectional clamping, ensuring a stable and secure transport device.

[0032] 2. This invention, with its inclined block, pressure plate, and push block, allows prefabricated components to be placed on top of the support plate of a transport frame. Once placed, a cylinder drives the push block to move, which in turn pushes the inclined block to move downwards. This causes the pressure plate to move downwards and press against the top of the prefabricated component, thus securing any loose prefabricated component on the transport frame. During disassembly, the cylinder drives the push block to return to its original position, and a spring pulls the pressure plate back to its original position. At this point, the pressure plate no longer holds the prefabricated component. This structure makes the fixing and disassembly of prefabricated components simple and convenient, and improves the installation speed.

[0033] 3. This invention, equipped with a support frame, locking block, and roller, allows a forklift to place prefabricated components onto a transport frame. The rotation of a first motor drives the roller to rotate, which in turn winds a pull rope, causing the limiting rod to rotate and opening the notch in the transport frame. At this point, a second spring is stretched. After placement, the first motor reverses, and the second spring returns the limiting rod to its original position. The limiting rod is now located at the bottom of the locking block. The rotation of the second motor drives a threaded rod to rotate, which engages with the threaded hole of an internal threaded plate. The rotation of the threaded rod moves the internal threaded plate, which in turn moves the locking block, which then embeds itself into the limiting rod, locking it in place. This structure allows for the placement of prefabricated components with longer lengths, freeing them from the restriction of the transport frame's fixing rods. Furthermore, the locking of the limiting rod is rapid after placement, preventing the prefabricated component from slipping out.

[0034] 4. This invention is equipped with a button, a touch panel, and a contact point. When the prefabricated component is placed, the prefabricated component presses against the touch panel, causing the prefabricated component to be supported by the support strip. At this time, the contact point is pressed down and contacts the button, causing the warning light to light up. This makes it easier for people in the vicinity to notice that the transport rack is loaded with prefabricated components. During transportation, it reduces the possibility of collisions with other vehicles, and the warning effect is more obvious at night. Attached Figure Description

[0047] Please see Figure 1 , Figure 2 and Figure 3A stable PC precast component transport device includes a transport frame 1, a support plate 2, and a fixing block 3. The fixing block 3 is installed on the outer wall of the transport frame 1, a movable plate 4 is installed on the inner wall of the fixing block 3, and a movable block 5 is installed on the outer wall of the movable plate 4, with one end of the movable block 5 extending out of the outer wall of the fixing block 3. A rotary knob 6 is installed on the outer wall of the movable block 5, and a screw 7 is installed at the end of the rotary knob 6, with one end of the screw 7 extending into the outer wall of the movable plate 4. A pentagonal block 8 is installed on the top of the movable block 5, and a pentagonal block 8 is installed at the bottom of the pentagonal block 8. There is a second screw 9, and a transmission plate 10 is installed on the outer wall of the second screw 9. A limiting plate 11 is installed at the bottom of the moving block 5. A top plate 13 is installed on the outer wall of the limiting plate 11, and the outer wall of the top plate 13 is connected to the outer wall of the transmission plate 10. A hydraulic rod 15 is installed on the inner top wall of the transport frame 1. A connecting plate 16 is installed at the bottom of the hydraulic rod 15. A roller 17 is installed at the bottom of the connecting plate 16. The fixing block 3 is located on the bottom outer wall of the transport frame 1, and four sets of fixing blocks 3 are evenly distributed on the outer wall of each set of rods of the transport frame 1. The side opening has four sets of notches, and the limiting plate 11 has a sliding groove. The transmission plate 10 and the top plate 13 are connected through the sliding groove. When the prefabricated component needs to be transported remotely, the transport frame 1 is transported to the flatbed truck by the rollers 17. Then, the hydraulic rod 15 drives the connecting plate 16 to move, and the movement of the connecting plate 16 drives the rollers 17 to move, so that the rollers 17 are raised, and the transport frame 1 contacts the flatbed truck. At this time, the limiting plate 11 is located on the outside of the flatbed truck body. The rotation of the rotary knob 6 drives the first screw 7 to rotate. The rotation of rod 7 causes the moving plate 4 to move, which in turn causes the moving block 5 to move. The moving block 5 clamps the limiting plate 11 on the outside of the flatbed, and at this time the top plate 13 is located on the bottom side of the flatbed. Then, the pentagonal block 8 is rotated by the tightening component. The rotation of the pentagonal block 8 causes the second screw 9 to rotate, which in turn causes the transmission plate 10 to rotate. The rotation of the transmission plate 10 causes the top plate 13 to move, thereby locking the transport frame 1 onto the flatbed and clamping it in both directions, making the transport device fixed and stable, and improving its stability.

[0048] Please see Figure 1 and Figure 4A cylinder 19 is installed on the inner wall of the support plate 2, and a push block 20 is installed at the output end of the cylinder 19. A telescopic rod 21 is installed on the inner top wall of the support plate 2, and a first spring 22 is installed on the inner top wall of the support plate 2. A pressure plate 23 is installed at the bottom of the telescopic rod 21, and an inclined block 24 is installed at the top of the pressure plate 23. The push block 20 is located on one side of the inclined block 24. One end of the first spring 22 is connected to the top of the pressure plate 23. The prefabricated component is placed on top of the support plate 2 of the transport frame 1. When the cylinder 19 moves the push block 20, the push block 20 moves and pushes the inclined block 24 to move. The inclined block 24 is squeezed and moves downward, so that the pressure plate 23 moves downward and presses against the top of the precast component, so that the loose precast component is stabilized on the transport frame 1. When disassembling, the cylinder 19 moves the push block 20 back to its original position, and the first spring 22 pulls the pressure plate 23 back to its original position. At this time, the pressure plate 23 no longer presses against the precast component. This structure makes the fixing and disassembly of the precast component simple and convenient, and improves the installation speed.

[0049] Please see Figure 5 and Figure 6 A support frame 25 is installed on the inner bottom wall of the transport frame 1. A limiting rod 26 is installed on the outer wall of the support frame 25. A second spring 27 is installed at the bottom of the limiting rod 26. One end of the second spring 27 is connected to the inner bottom wall of the transport frame 1. A fixing plate 28 is installed on the outer wall of the transport frame 1. A motor 29 is installed on the outer wall of the fixing plate 28. A reel 30 is installed at the output end of the motor 29. A pull rope 31 is installed on the outer wall of the reel 30, and one end of the pull rope 31 is connected to the outer wall of the limiting rod 26. A second motor 32 is installed on the inner top wall of the transport frame 1. A threaded rod 33 is installed at the output end of the motor 32. An internal threaded plate 34 is installed on the outer wall of the threaded rod 33. A locking block 35 is installed at the bottom of the internal threaded plate 34. When a forklift places the prefabricated component on the transport frame 1, the first motor 29 rotates, driving the reel 30 to rotate. Rotating the pull rope 31 causes the pull rope 31 to rotate, which in turn pulls the limiting rod 26 to rotate, opening the notch in the transport frame 1. At this time, the second spring 27 is stretched. After placement, the first motor 29 reverses, and the second spring 27 restores the limiting rod 26. At this time, the limiting rod 26 is located on the bottom side of the locking block 35. The second motor 32 rotates, driving the threaded rod 33 to rotate. The threaded rod 33 engages with the threaded hole of the internal threaded plate 34. The rotation of the threaded rod 33 drives the internal threaded plate 34 to move, which in turn drives the locking block 35 to move. The locking block 35 moves and embeds itself into the limiting rod 26, locking the limiting rod 26. The notch in the transport frame 1 with this structure allows prefabricated components with larger lengths to be placed into the transport frame 1, so that the placement of prefabricated components is not restricted by the fixing rod of the transport frame 1. Moreover, after placement, the locking of the limiting rod 26 is quick, preventing the prefabricated components from slipping out.

[0050] Please see Figure 1 and Figure 7A support bar 36 is installed on the top of the support plate 2. A connecting plate 37 is installed on the inner wall of the support bar 36. A touch plate 38 is installed on the top of the connecting plate 37. A contact point 39 is installed on the bottom of the connecting plate 37. A button 40 is installed on the inner wall of the support bar 36. A No. 3 spring 41 is installed on the inner bottom wall of the support bar 36, and one end of the No. 3 spring 41 is connected to the bottom of the connecting plate 37. A warning light 42 is installed on the outer wall of the transport frame 1. When the prefabricated component is placed, the prefabricated component touches the touch plate 38, so that the prefabricated component is supported by the support bar 36. At this time, the contact point 39 is pressed down and contacts the button 40, so that the warning light 42 lights up, making it easier for people around to notice that the transport frame 1 is loaded with prefabricated components. During transportation, the possibility of collision with other vehicles is reduced, and the warning effect is more obvious at night.

[0051] The operating steps of this transport device are as follows:

[0052] S1. When prefabricated components need to be transported remotely within the transport frame 1, the transport frame 1 is transported to a flatbed truck via rollers 17. Subsequently, hydraulic rod 15 drives connecting plate 16 to move, which in turn drives roller 17 to move, causing roller 17 to rise and contact the transport frame 1 with the flatbed truck. At this time, limiting plate 11 is located on the outside of the flatbed truck body. Rotating knob 6 drives screw 7 to rotate, which in turn drives moving plate 4 to move, which in turn drives moving block 5 to move. Moving block 5 clamps limiting plate 11 on the outside of the flatbed truck body, and at this time, top plate 13 is located on the bottom side of the flatbed truck body. Then, pentagonal block 8 is rotated by tightening component, which drives screw 9 to rotate, which in turn drives transmission plate 10 to rotate, which in turn drives top plate 13 to move, thereby locking the transport frame 1 onto the flatbed truck and clamping it in both directions, making the transport device fixed and stable, and improving stability.

[0053] S2. The precast component is placed on the top of the support plate 2 of the transport frame 1. When the placement is completed, the cylinder 19 drives the push block 20 to move. The push block 20 moves and pushes the inclined block 24 to move. The inclined block 24 is squeezed and moves downward, so that the pressure plate 23 moves downward and presses the top of the precast component, so that the loose precast component is stabilized on the transport frame 1. When disassembling, the cylinder 19 drives the push block 20 to return to its original state, and the first spring 22 pulls the pressure plate 23 back to its original state. At this time, the pressure plate 23 no longer presses the precast component. This structure makes the fixing and disassembly of the precast component simple and convenient, and improves the installation speed.

[0054] S3. When the precast component is placed on the transport frame 1 by the forklift, the first motor 29 rotates and drives the reel 30 to rotate. The reel 30 rotates and winds the pull rope 31. The pull rope 31 pulls the limiting rod 26 to rotate, so that the notch of the transport frame 1 opens. At this time, the second spring 27 is stretched. After the placement is completed, the first motor 29 reverses and the second spring 27 restores the limiting rod 26. At this time, the limiting rod 26 is located on the bottom side of the locking block 35. The second motor 32 rotates and drives the threaded rod 33 to rotate. The threaded rod 33 engages with the threaded hole of the internal threaded plate 34. The rotation of the threaded rod 33 drives the internal threaded plate 34 to move. The movement of the internal threaded plate 34 drives the locking block 35 to move. The locking block 35 moves and embeds into the limiting rod 26, so that the limiting rod 26 is locked. The notch opened in the transport frame 1 in this structure allows precast components with larger lengths to be placed into the transport frame 1. The placement of the precast components is not restricted by the fixed rod of the transport frame 1. After placement, the locking of the limiting rod 26 is quick, preventing the precast components from slipping out.

[0055] S4. When the precast component is placed, the precast component touches the contact plate 38, so that the precast component is supported by the support bar 36. At this time, the contact point 39 is pressed down and contacts the button 40, so that the warning light 42 is lit, thereby making it easier for people around to notice that the transport rack 1 is loaded with precast components. During transportation, the possibility of collision with other vehicles is reduced, and the warning effect is more obvious at night.

[0056] Step S1 also includes the following steps:

[0057] S11. When moving, the hydraulic rod 15 drives the roller 17 to move down, so that the transport frame 1 is supported by the roller 17. When stable, the hydraulic rod 15 drives the roller 17 to move up, so that the bottom of the transport frame 1 contacts the placement surface.

[0058] Step S3 also includes the following steps:

[0059] S31, most of the second spring 27 is embedded inside the notch of the transport frame 1, and the limiting rod 26 is movably connected to the support frame 25, so that the limiting rod 26 can rotate on the support frame 25;

[0060] Step S4 also includes the following steps:

[0061] S41, its warning lights are distributed around the transport frame 1. When the prefabricated component is removed, the No. 3 spring 41 can restore the connecting plate 37, so that the contact 39 and the button 40 are no longer in contact, and the warning light 42 can be turned off.

[0062] Working principle: When prefabricated components need to be transported remotely, the transport frame 1 is placed inside the transport frame 1. The transport frame 1 is then transported to the flatbed truck via rollers 17. Subsequently, hydraulic rod 15 drives connecting plate 16 to move, which in turn drives roller 17 to move, causing roller 17 to rise and bring the transport frame 1 into contact with the flatbed truck. At this time, the limiting plate 11 is located on the outside of the flatbed truck body. Rotating knob 6 drives screw 7 to rotate, which in turn drives moving plate 4 to move, which in turn drives moving block 5 to move. Moving block 5 clamps the limiting plate 11 on the outside of the flatbed truck body, and at this time, the top plate 13 is located on the bottom side of the flatbed truck body. Then, the pentagonal block 8 is rotated by tightening components, which in turn drives the second... The rotation of screw 9 drives the transmission plate 10 to rotate, which in turn moves the top plate 13, thus locking the transport frame 1 onto the flatbed truck and clamping it in both directions. This ensures the transport device is securely fixed and stable, improving its stability. The precast component is placed on top of the support plate 2 of the transport frame 1. Upon placement, cylinder 19 moves push block 20, which in turn moves inclined block 24, causing it to be pressed downwards. This causes pressure plate 23 to move downwards and press against the top of the precast component, securing any loose precast component on the transport frame 1. During disassembly, cylinder 19 moves push block 20 back to its original position, and spring 22 pulls pressure plate 23 back to its original position, at which point pressure plate 23 no longer presses against the component. The prefabricated components are easy to fix and disassemble, improving installation speed. When the prefabricated components are placed on the transport frame 1 by a forklift, the first motor 29 rotates, driving the winch 30 to rotate. The winch 30 winds the pull rope 31, which pulls the limiting rod 26 to rotate, opening the notch in the transport frame 1. At this time, the second spring 27 is stretched. After placement, the first motor 29 reverses, and the second spring 27 restores the limiting rod 26. At this time, the limiting rod 26 is located on the bottom side of the locking block 35. The second motor 32 rotates, driving the threaded rod 33 to rotate. The threaded rod 33 engages with the threaded hole of the internal threaded plate 34. The rotation of the threaded rod 33 drives the internal threaded plate 34 to move, and the movement of the internal threaded plate 34... The movable locking block 35 moves and embeds itself into the limiting rod 26, locking the limiting rod 26. The notch in the transport frame 1 allows for the placement of prefabricated components of greater length, ensuring that the placement of prefabricated components is not restricted by the fixed rod of the transport frame 1. After placement, the limiting rod 26 locks quickly, preventing the prefabricated components from slipping out. When the prefabricated component is placed, it touches the contact plate 38, which supports the component on the support bar 36. At this time, the contact point 39 is pressed down and contacts the button 40, causing the warning light 42 to light up. This makes it easier for people in the vicinity to notice that the transport frame 1 is loaded with prefabricated components, reducing the possibility of collisions with other vehicles during transport, and the warning effect is more obvious at night.
