Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically, to a roof panel loading and transport device and its construction method. Background Technology

[0002] Roof panels are boards that can directly bear the load of the roof. In the past, roof panel installation usually involved producing roof panels on the ground using a roof panel forming machine, cutting them, and then bundling and hoisting them onto the roof. However, for roof panels with long single-panel lengths, the span of the roof panels was large during hoisting, requiring two or even more cranes to work together, which resulted in low conveying efficiency of the roof panels.

[0003] To improve the conveying efficiency of roof panels, existing technologies can also use cableways to transport the roof panels. Specifically, a cableway is set up between the ground and the roof, and guide rollers are installed on the cableway. The panel material produced by the forming machine is guided by the cableway and guide rollers and conveyed to the roof.

[0004] When the building roof is high, the required conveying span needs to be increased to ensure a suitable conveying angle. This means the conveying stroke of the panel material increases. As the cableway length increases, the downward bending of the cableway due to its own weight also increases. Furthermore, the guide rollers are spaced apart, with a large space between adjacent rollers. When the cableway is drooping, the guide rollers cannot be distributed in a straight line. When the end of the roof panel moves into the area between two adjacent guide rollers, because the guide rollers are distributed along a drooping curve, and the panel end lacks support between adjacent rollers, it will move in a straight line. Therefore, the panel end can easily enter the area under the next guide roller, causing it to get stuck or pass under the next guide roller, resulting in construction accidents.

[0005] To effectively guide the panel, the guide rollers can be replaced with a base plate structure laid on the cableway to support and guide the panel throughout the process, preventing the end of the panel from going out of the cableway.

[0006] However, due to the long transport distance required for the roof panels, the friction between the roof panels and the base plate increases during continuous transport, leading to a rise in the temperature of the roof panels. As the material temperature increases, its plastic deformation capacity increases, causing the roof panels in the area of ​​greatest bending to go beyond the elastic deformation range where they were originally within the range of elastic deformation. In other words, under the same bending deformation, the higher the material temperature, the easier it is for irreversible plastic deformation to occur. Therefore, the roof panel material at the location of the greatest bending of the cableway will experience irreversible deformation due to the increased temperature. This deformation will directly affect the installation accuracy and effect of the roof panels, increasing construction costs. Summary of the Invention

[0007] The present invention provides a roof panel loading and transportation device and its construction method, which aims to solve the technical problem of irreversible plastic deformation caused by friction when using a base plate and cableway to transport roof panels.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a roof panel loading and transport device, comprising a cableway conveying system, the cableway conveying system comprising a steel cable and a bottom support plate, the two ends of the steel cable being fixedly installed on a roof panel forming machine and a roof receiving platform respectively, and the bottom support plate being connected to the steel cable through a fixed frame;

[0009] Multiple sets of lubrication units are spaced apart on the bottom support plate. The lubrication units are used to provide lubricating oil to the mating surfaces of the roof panel and the bottom support plate. An oil remover is installed at the end of the bottom support plate near the roof receiving platform. The oil remover is used to clean the lubricating oil on the bottom of the roof panel before the roof panel outputs to the cableway conveyor system.

[0010] The lubrication unit includes an oil brush box, which is fixedly mounted on the base plate. A rotating roller is rotatably mounted in the oil brush box, and an oil brush sleeve is fixedly mounted on the circumferential side wall of the roller. The oil brush box stores lubricating oil, and the edge of the oil brush sleeve extends beyond the conveying plane of the base plate. The bottom of the oil brush sleeve is immersed below the lubricating oil surface to absorb the lubricating oil. When the roof panel comes into contact with the oil brush sleeve, the oil brush sleeve applies lubricating oil to the bottom of the roof panel.

[0011] In a preferred embodiment, an oil overflow slit is provided on the side of the oil brush box near the bottom of the cableway conveyor system, and a movable plate is installed at the bottom of the lubrication unit.

[0012] In a preferred embodiment, the bottom of the brush box is arc-shaped, the movable plate is an arc-shaped structure that fits into the bottom of the brush box, the bottom of the brush box is fixedly connected to a slide rail, the movable plate is slidably installed in the slide rail, and the movable plate slides against the bottom of the brush box. Multiple oil overflow seams are provided, and the multiple oil overflow seams are distributed at intervals along the arc direction of the bottom of the brush box. The movable plate is provided with an oil overflow port that matches the oil overflow seam, and a counterweight is provided on the oil overflow pipe.

[0013] In a preferred embodiment, the rotating roller is a hollow tube structure, with both ends of the rotating roller penetrating through the end walls of the brush box and rotatably connected to the brush box. The rotating roller has a thin-walled structure.

[0014] In a preferred embodiment, the oil separator includes an oil collection box and an auxiliary pressure roller. The oil collection box is fixedly installed at the bottom of the base plate, and an opening is provided at the top of the oil collection box, which extends to the surface of the base plate. The auxiliary pressure roller is positioned above the roof panel to squeeze the roof panel. The auxiliary pressure roller is mounted on the base plate via a pressure roller frame and is rotatably mounted in the pressure roller frame. An oil drain pipe is fixedly installed at the bottom of the oil collection box, and multiple oil scrapers are fixedly installed at the bottom of the oil collection box, with the top of the oil scrapers adhering to the bottom wall of the roof panel.

[0015] In a preferred embodiment, a cleaning brush roller is also provided inside the oil collection box. The cleaning brush roller is driven by a motor to rotate inside the oil collection box. The cleaning brush roller is in contact with the bottom of the roof panel. The rotation direction of the contact point between the cleaning brush roller and the roof panel is opposite to the conveying direction of the roof panel. The cleaning brush roller has a sponge structure. An oil pressure plate is fixedly installed in the oil collection box. The oil pressure plate extends towards the center of the cleaning brush roller and squeezes the cleaning brush roller.

[0016] In a preferred embodiment, the lubrication unit further includes an oil reservoir and an oil pump. The oil pump inlet is connected to the oil reservoir, and the oil pump outlet is connected via a hose to the oil inlet pipe of the brush box located at the top. The overflow pipe of each brush box is connected via a hose to the oil inlet pipe of the adjacent brush box located below it. The overflow pipe of the brush box located at the bottom is connected to the oil reservoir via a hose, and the drain pipe is connected via a hose to the oil inlet pipe of the brush box located at the top.

[0017] In a preferred embodiment, a plurality of oil blowers are provided on the base plate along its length. Each oil blower includes a plurality of air blowing boxes, which are distributed on both sides of the roof panel corrugations. The air blowing boxes are hollow structures, and a plurality of air blowing holes are provided on the side of the air blowing box near the roof panel corrugations. The air blowing holes are inclined downward and towards the conveying direction of the roof panel on the side near the corrugations. The air blowing boxes are connected to an air supply mechanism for providing airflow into the air blowing boxes.

[0018] In a preferred embodiment, the air supply mechanism is an air injector, which is fixedly installed at the bottom of the air blowing box. The air injector has two air inlet chambers, one end of which is open, and the opening directions of the two air inlet chambers are opposite. The air injector is located at the bottom of the base plate, and a connecting hole is provided between the air inlet chamber and the air blowing box.

[0019] A method for transporting and constructing roof panels includes the following steps:

[0020] Step 1: Install the roof panel forming machine at the corresponding position on the ground and adjust the tilt angle of the roof panel forming machine. Build a roof receiving platform at the location of the skylight on the building roof. Then fix both ends of each steel cable to the roof panel forming machine and the roof receiving platform respectively. Then install a fixing frame on the steel cable and lay a bottom support plate in the fixing frame to complete the construction of the cableway conveyor system.

[0021] Step 2: Set up a warning line in the relevant area and have a designated person in charge of supervision to ensure that no other workers are walking in the hoisting area. At the same time, use a loudspeaker to play warning messages in a loop.

[0022] Step 3: The roof panel forming machine rolls the sheet material into roof panels. The end of the roof panel is introduced into the bottom support plate. With the conveying thrust generated during the processing of the roof panel forming machine, the roof panel is pushed along the bottom support plate to the roof.

[0023] Step 4: The lubrication unit adds lubricating oil between the roof panel and the bottom support plate for lubrication. After scraping off the lubricating oil on the bottom of the roof panel through the oil remover at the top of the cableway conveying system, it outputs the lubricating oil to the roof receiving platform.

[0024] Step 5: After the roof panels are transported to the roof, they are cut according to the actual measurement data on site. Then, along the direction of the roof panels, a worker stands at a position of 5 meters and exerts force to lift the roof panels over his shoulders and move them forward.

[0025] The beneficial effects of this invention are as follows:

[0026] This invention utilizes the rolling motion of the oil brush sleeve to apply lubricating oil to the base plate, reducing friction between the roof panel and the base plate. This reduces the heat generated by friction in the roof panel material, preventing the roof panel from overheating and causing irreversible plastic deformation when passing through the area of ​​maximum bending of the cableway. This improves the efficiency of roof panel transportation while also enhancing the safety of roof panel transportation.

[0027] During the conveying of the roof panel, the air blown out by the air box of the present invention will blow the squeezed-out lubricating oil between the corrugated bottom wall and the bottom support plate, reducing the leakage of lubricating oil. At the same time, the blown air can also move forward and form a circulating airflow between the roof panel and the bottom support plate. This airflow can carry away a large amount of heat on the roof panel, which can further reduce the temperature of the roof panel and improve the protection effect of the roof panel.

[0045] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0046] Refer to the instruction manual appendix Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 A roof panel loading and transport device includes a cableway conveying system 1, which includes a steel cable 11 and a bottom support plate 12. The two ends of the steel cable 11 are fixedly installed on the roof panel forming machine 2 and the roof receiving platform 3, respectively. The bottom support plate 12 is connected to the steel cable 11 through a fixed frame 13. The bottom support plate 12 is used to guide and transport the roof panels produced by the roof panel forming machine 2. Multiple sets of lubrication units 4 are arranged at intervals on the bottom support plate 12. The lubrication units 4 are used to provide lubricating oil to the mating surfaces of the roof panel and the bottom support plate 12. An oil remover 6 is provided at one end of the bottom support plate 12 near the roof receiving platform 3. The oil remover 6 is used to clean the lubricating oil on the bottom of the roof panel before the roof panel is output from the cableway conveying system 1.

[0047] Refer to the instruction manual appendix Figure 6The lubrication unit 4 includes an oil brush box 41, which is fixedly mounted on the base plate 12. A rotating roller 42 is rotatably mounted in the oil brush box 41, and an oil brush sleeve 43 is fixedly mounted on the circumferential side wall of the rotating roller 42. The oil brush box 41 stores lubricating oil. The edge of the oil brush sleeve 43 extends beyond the conveying plane of the base plate 12, thereby creating a certain pressure on the oil brush sleeve 43 when the roof panel passes over it, increasing the frictional resistance between the roof panel and the oil brush sleeve 43. This causes the oil brush sleeve 43 and the rotating roller 42 to rotate during the conveying of the roof panel. The bottom of the oil brush sleeve 43 is immersed below the lubricating oil surface to absorb the lubricating oil. Specifically, the oil brush sleeve 43 can be made of a soft brush structure, a sponge structure, or other materials that can absorb lubricating oil and cause it to be extruded during compression. Specifically, the roof panel moves on the base plate 12 and interacts with the oil brush sleeve 43. When the oil sleeve 43 contacts the roof panel, it applies lubricating oil to the bottom of the roof panel. At the same time, the friction between the roof panel and the oil sleeve 43 drives the oil sleeve 43 and the rotating roller 42 to rotate, allowing the oil sleeve 43 to circulate and absorb lubricating oil. When it contacts the roof panel again, it applies lubricating oil to the bottom of the roof panel, thus forming a barrier between the roof panel and the bottom support plate 12 during the continuous forward movement. This reduces the friction between the roof panel and the bottom support plate 12, thereby reducing the heat generated by the friction of the roof panel material. This prevents the roof panel from overheating and causing irreversible plastic deformation when passing through the area of ​​maximum bending of the cableway. Furthermore, the operation with lubricating oil can accelerate the production and conveying efficiency of the roof panel, thereby improving the safety protection of the roof panel during conveying.

[0048] It should be noted that the instructions are attached. Figure 2 The roof receiving platform 3 is located at the skylight position in the building. The roof panel forming machine 2 is located on the ground and inside the container. According to the design angle of the cableway conveying system 1, a pad structure is used to raise the discharge end of the roof panel forming machine 2, so that the container is tilted and adapted to the cableway conveying system 1. Among them, four sets of steel cables 11 can be set. The fixed frame 13 is a rectangular frame structure. The four sets of steel cables 11 are distributed on the outside of the fixed frame 13. The bottom support plate 12 is laid on the fixed frame 13 to form a conveying system. In this embodiment, the bottom support plate 12 can be a U-shaped color steel bottom plate, which is composed of a whole integrated bottom plate structure. The whole plate is seamless. The plate material roll is set at the feed end of the roof panel forming machine 2. The roof panel rolled out by the roof panel forming machine 2 is directly fed onto the roof through the cableway conveying system 1 by the conveying force generated during the processing of the roof panel forming machine 2.

[0049] Furthermore, to facilitate the installation of the base plate 12, this embodiment also provides another design scheme for the base plate 12. For details, please refer to the appendix to the instruction manual. Figure 5The bottom support plate 12 is composed of multiple individual short support plates spliced ​​together, with the end of the lower individual short support plate overlapping the end of the upper individual short support plate, and then fixed by bolts or rivets and other connectors to ensure that the joint between two adjacent individual short support plates does not obstruct the advance of the roof panel end.

[0050] In the above embodiment, since the base plate 12 is inclined with a gradually increasing inclination angle, some of the oil brushed on the roof panel will flow downwards along the base plate 12. When it flows to the oil brush box 41 below, it can just fall into the oil brush box 41. However, if it continues to receive oil, the oil in the oil brush box 41 will overflow, affecting the brushing effect of the oil brush sleeve 43. Therefore, in order to avoid excessive lubricating oil in the oil brush box 41, this embodiment also provides the following technical solution. For details, please refer to the appendix of the specification. Figure 6 , Figure 7 , Figure 8 and Figure 9 An oil overflow slit 412 is provided on the side of the oil brush box 41 near the bottom of the cableway conveying system 1. A movable plate 45 is installed at the bottom of the lubrication unit 4. The movable plate 45 has a hollow structure and is connected to the oil overflow slit 412. An oil overflow pipe 46 is fixedly installed at the bottom of the movable plate 45. When the lubricating oil level in the oil brush box 41 reaches the oil overflow slit 412, it can be discharged through the movable plate 45 and the oil overflow pipe 46 to avoid excessive lubricating oil in the oil brush box 41.

[0051] It should be noted that the instruction manual includes... Figure 2 In the process, due to the gravity of the cross material, the cableway system 1 will bend downwards. a, b and c are three different sections on the cableway system 1. The inclination angles of section a and section b are different. Section b is the place with the greatest bending in the entire cableway system 1, and it is also the place where the roof panel material deforms the most.

[0052] Furthermore, as the height of the cableway conveyor system 1 increases, the tilt angle of the base plate 12 also changes, which in turn causes the tilt angle of the oil brush box 41 to change as well, for example, the attached... Figure 6 To be continued Figure 7 If only a single and fixed oil overflow slit 412 is provided, the amount of lubricating oil stored in the oil brush box 41 will change when the position of the oil overflow slit 412 changes due to the change in the tilt angle of the oil brush box 41. To ensure that all oil brush boxes 41 always store the same amount of lubricating oil, this embodiment also provides the following technical solution, which can be found in the appendix of the specification. Figure 6 and Figure 9The bottom of the brushing box 41 is arc-shaped, and the movable plate 45 is an arc-shaped structure that fits into the bottom of the brushing box 41. The bottom of the brushing box 41 is fixedly connected to a slide rail 411. The movable plate 45 is slidably installed in the slide rail 411 and slides against the bottom of the brushing box 41. Multiple oil overflow seams 412 are provided, and the multiple oil overflow seams 412 are distributed at intervals along the arc direction of the bottom of the brushing box 41. An oil overflow port 451 that is compatible with the oil overflow seam 412 is provided in the movable plate 45. A counterweight is provided on the oil overflow pipe 46.

[0053] It should be noted that the oil overflow port 451 is connected to the corresponding oil overflow seam 412 only when the oil overflow seam 412 is aligned with the movable plate 45. Only then can the lubricating oil in the oil brush box 41 flow into the movable plate 45 and be discharged through the oil overflow pipe 46. In actual use, although the tilt angles of each oil brush box 41 are different, the oil overflow pipe 46 can be kept vertical under the action of the counterweight. This makes the height between the oil overflow port 451 and the bottom of the inner wall of the oil brush box 41 relatively fixed. In other words, the height of the oil overflow from the oil overflow seam 412 in the oil brush box 41 is fixed, the amount of lubricating oil stored in the oil brush box 41 remains unchanged, and the amount of lubricating oil in each oil brush box 41 is basically the same.

[0054] Furthermore, in the above technical solutions, please refer to the appendix to the specification. Figure 6 and Figure 9 The rotating roller 42 is a hollow tube structure. Both ends of the rotating roller 42 penetrate the end walls of the brush box 41 and are rotatably connected to the brush box 41. The rotating roller 42 is a thin-walled structure. In actual use, the wind in the construction environment can pass through the rotating roller 42. When the airflow flows through the rotating roller 42, it can carry away the heat of the rotating roller 42, thereby dissipating heat from the lubricating oil in the brush box 41, avoiding excessive heat caused by the circulation of the lubricating oil, and reducing the impact of the heat of the lubricating oil on the heat of the roof panel.

[0055] Further, please refer to the appendix to the instruction manual. Figure 10 In the above embodiment, the oil remover 6 includes an oil collection box 61 and an auxiliary pressure roller 66. The oil collection box 61 is fixedly installed on the bottom of the base plate 12. The top of the oil collection box 61 is provided with an opening that extends to the surface of the base plate 12. The auxiliary pressure roller 66 is arranged above the roof panel to squeeze the roof panel. The auxiliary pressure roller 66 is installed on the base plate 12 through a pressure roller frame 67 and is rotatably installed in the pressure roller frame 67. An oil drain pipe 63 is fixedly installed at the bottom of the oil collection box 61. Multiple oil scrapers 62 are fixedly installed at the bottom of the oil collection box 61. The top of the oil scraper 62 is in contact with the bottom wall of the roof panel. During the conveying of the roof panel, the oil scraper 62 is used to scrape off the lubricating oil on the bottom of the roof panel. The scraped lubricating oil is discharged from the oil drain pipe 63.

[0056] Furthermore, a cleaning brush roller 64 is also provided inside the oil collection box 61. The cleaning brush roller 64 is driven by a motor to rotate inside the oil collection box 61. The cleaning brush roller 64 is in contact with the bottom of the roof panel. The rotation direction of the contact point between the cleaning brush roller 64 and the roof panel is opposite to the conveying direction of the roof panel. The cleaning brush roller 64 has a sponge structure. An oil pressure plate 65 is fixedly installed in the oil collection box 61. The oil pressure plate 65 extends towards the center of the cleaning brush roller 64 and squeezes the cleaning brush roller 64.

[0057] It should be noted that during the conveying of the roof panel, the scraper 62 first scrapes the oil off the roof panel, and then the cleaning brush roller 64 rotates to wipe the bottom of the roof panel. When the cleaning brush roller 64 passes the pressure plate 65, the pressure plate 65 scrapes out the lubricating oil in the cleaning brush roller 64, so that it falls into the oil collection box 61 and is then discharged through the oil drain pipe 63.

[0058] Furthermore, as the equipment continues to be used, the lubricating oil in the topmost brush box 41 will gradually decrease. Therefore, this embodiment also provides a lubricating oil supply system. Specifically, the lubrication unit 4 also includes an oil storage tank and an oil pump. The oil pump inlet is connected to the oil storage tank, and the oil pump outlet is connected to the oil inlet pipe 44 of the top brush box 41 via a hose. The overflow pipe 46 of each brush box 41 is connected to the oil inlet pipe 44 of the adjacent brush box 41 below it via a hose. The overflow pipe 46 of the bottom brush box 41 is connected to the oil storage tank via a hose, and the drain pipe 63 is connected to the oil inlet pipe 44 of the top brush box 41 via a hose.

[0059] It should be noted that oil can be continuously supplied to the top oil brush box 41 by an oil pump. The lubricating oil scraped by the oil remover 6 also flows directly to the top oil brush box 41. Excess lubricating oil in the oil brush box 41 will be discharged downward through the overflow slit 412 and flow to the next oil brush box 41. This cycle continues until the excess lubricating oil flows back to the storage tank. With the cooperation of the overflow slit 412 and the movable plate 45, the amount of lubricating oil in each oil brush box 41 can also remain stable.

[0060] In the above embodiments, if the roof panel being transported has a structure with multiple corrugations, the lubrication unit 4 can be directly installed at the bottom of the corrugations that contact the base plate 12. However, in actual use, the lubricating oil at the bottom of the corrugations is easily squeezed out to both sides of the corrugations under the pressure of the roof panel's gravity. To ensure that sufficient lubricating oil is filled between the bottom of the corrugations and the base plate 12 during transportation, this embodiment also provides the following technical solution, which is detailed in the appendix to the instruction manual. Figure 12 , Figure 13 , Figure 14 and Figure 15Multiple sets of oil blowers 5 are arranged on the base plate 12 along its length. Each set of oil blowers 5 includes multiple air blowing boxes 51, which are distributed on both sides of the roof panel corrugation. The air blowing boxes 51 are hollow structures, and multiple air blowing holes 511 are opened on the side of the air blowing box 51 near the roof panel corrugation. The air blowing holes 511 are inclined downward and towards the conveying direction of the roof panel on the side near the corrugation. The air blowing box 51 is connected to an air supply mechanism, which is used to provide airflow into the air blowing box 51, so that the airflow is blown out at an angle from the air blowing holes 511. The airflow blows downward towards the edge where the corrugation and the base plate 12 are in contact, which can blow the squeezed-out lubricating oil between the bottom wall of the corrugation and the base plate 12, reducing the leakage of lubricating oil. At the same time, the blown airflow can also move forward, forming a circulating airflow between the roof panel and the base plate 12. This airflow can carry away a large amount of heat on the roof panel, which can further reduce the temperature of the roof panel and improve the protection effect of the roof panel.

[0061] Furthermore, the air supply mechanism can be an air injector 52, which is fixedly installed at the bottom of the air blowing box 51. The air injector 52 has two air inlet chambers 521, one end of which is open, and the openings of the two air inlet chambers 521 are in opposite directions. The air injector 52 is located at the bottom of the base plate 12, and a connecting hole is provided between the air inlet chambers 521 and the air blowing box 51. In actual use, the wind at the construction site will generate airflow that blows into the air inlet chambers 521, allowing the airflow to enter the air blowing box 51. The arrangement of the two air inlet chambers 521 can absorb wind from different directions, improving the air supply effect. It should be noted that if the construction environment is a low-wind environment, an air pump and air pipe can be directly connected to the air blowing box 51 to directly supply air to the air blowing box 51. If necessary, a cooling device can be used to cool the delivered gas to improve the heat dissipation effect.

[0062] Refer to the instruction manual appendix Figure 16 A method for transporting and constructing roof panels includes the following steps:

[0063] Step 1: Install the roof panel forming machine 2 at the corresponding position on the ground and adjust the tilt angle of the roof panel forming machine 2. Build the roof receiving platform 3 at the location of the skylight on the building roof. Then fix both ends of each steel cable 11 to the roof panel forming machine 2 and the roof receiving platform 3 respectively. Then install the fixing frame 13 on the steel cable 11 and lay the bottom support plate 12 in the fixing frame 13 to complete the construction of the cableway conveying system 1.

[0064] Step 2: Set up a warning line in the relevant area and have a designated person in charge of supervision to ensure that no other workers are walking in the hoisting area. At the same time, use a loudspeaker to play warning messages in a loop.

[0065] Step 3: Start the roof panel forming machine 2 to roll the board material into a roof panel. The end of the roof panel is introduced into the bottom support plate 12.
