[0002] A roofing panel is a panel that can directly bear the roofing load. The roofing panel is located on the roof of a house and is generally made of metals such as aluminum-magnesium-manganese or alloys. After the roofing panels are assembled on the gable inclined beams at the top floor of the house, the wing plates overlap and cover each other so that no exposed vertical seams appear in multiple single-box roofing panels, forming a pitched roof with good integrity.

The damaged prefabricated roofing panels do not meet the construction standards, thus affecting the construction efficiency and progress. For this reason, we designed an equipment that can directly press and bend roofing panels at the construction site. Summary of the Invention

Detailed implementation manner

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] Refer to Figures 1-7 , a profiled and bent equipment for roof panels used at the construction site, including a pressing frame 1. A second side wall 5 is provided on one side of the pressing frame 1, and a first side wall 4 is provided on the other side. A plurality of rotating shafts 9 are rotatably installed between the first side wall 4 and the second side wall 5. Limiting wheels 6, extrusion wheels 7, and rolling wheels 8 are detachably and fixedly clamped on the rotating shafts 9. The limiting wheels 6 are used to limit the two ends of the conveyed roof panel, the rolling wheels 8 are used to extrude protrusions on the roof panel, and the extrusion wheels 7 are used to extrude depressions on the roof panel;

[0029] One end of the pressing frame 1 is a conveying end, and a limiting mechanism 11 is provided on the conveying end. The other end of the pressing frame 1 is an output end, and the conveying end is connected to a bending frame 12. A bending mechanism is provided on the bending frame 12. The bending mechanism includes a first extrusion roller 13, a second extrusion roller 14, and a third extrusion roller 15. The second extrusion roller 14 and the third extrusion roller 15 are symmetrically arranged relative to the first extrusion roller 13. Adjusting mechanisms 17 for changing the mutual distance between the first extrusion roller 13, the second extrusion roller 14, and the third extrusion roller 15 are respectively provided at both ends of the first extrusion roller 13, the second extrusion roller 14, and the third extrusion roller 15. The adjusting mechanism 17 includes a threaded rod 30 and a bracket 26;

[0030] A plurality of installation grooves 16 are opened on the first side wall 4. An installation mechanism is provided in the installation grooves 16. One end of each rotating shaft 9 is rotatably inserted into the second side wall 5, and the other end is rotatably installed in each installation groove 16 through the installation mechanism.

[0031] There are two limiting wheels 6 provided on the rotating shaft 9, and they are respectively fixedly clamped at both ends of the rotating shaft 9. The pressing wheel 7 is arranged between two adjacent rolling wheels 8. When pressing the roof panel, by reasonably distributing the number and positions of the pressing wheel 7 and the rolling wheels 8, the roof panel can be pressed into the required position shape. The rolling wheels 8 press the roof panel downward, and the pressing wheel 7 is used in cooperation with the rolling wheels 8 on both sides, and a protruding structure can be extruded by the pressing wheel 7.

[0032] The limiting mechanism 11 includes an L-shaped shaft 27, a V-shaped plate 28, and a linkage shaft 10. The L-shaped shaft 27 is fixedly installed on the side of the pressing frame 1. The V-shaped plate 28 is rotatably connected to the end of the L-shaped shaft 27. A cylinder 29 is rotatably installed on the side of the L-shaped shaft 27. The driving end of the cylinder 29 is rotatably connected to one end of the V-shaped plate 28. A groove is provided in the V-shaped plate 28 for clamping the edge of the roof panel. The linkage shaft 10 is rotatably connected to the other end of the V-shaped plate 28. When transporting the roof panel onto the pressing frame 1, both ends of the roof panel are respectively clamped in the grooves of the V-shaped plates 28 on both sides, and the two sides of the roof panel are controlled within a limited range before good pressing can be carried out. The cylinder 29 can change the angle of the V-shaped plate 28 through its driving end and can be adjusted adaptively to meet different pressing requirements.

[0033] Chute grooves 37 are provided on both of the two linkage shafts 10, and an intermediate shaft 35 is inserted between the two chute grooves 37. Second elastic pieces 36 are fixedly connected to the ends of the two linkage shafts 10, and the other ends of the second elastic pieces 36 are slidably inserted into the chute grooves 37 on the other linkage shaft 10. When transporting the roof panel, both ends of the roof panel are restricted by the V-shaped plates 28, and the roof panel deforms due to extrusion. When deforming, the lower part of the roof panel is restricted by the pressing frame 1, and the upper part is restricted by the linkage shafts 10. The two linkage shafts 10 are connected together through the intermediate shaft 35, and both ends can slide relative to the chute grooves 37 through the elastic second elastic pieces 36. The deformed roof panel may apply pressure to the linkage shafts 10, squeezing the two linkage shafts 10 and changing the angle between them. The second elastic pieces 36 can be bent adaptively, and at the same time, the elastic second elastic pieces 36 can also control the degree of deformation of the roof panel to prevent the roof panel from detaching from between the two V-shaped plates 28.

[0034] On one side of the bending frame 12, a rotating motor 25 is fixedly installed. The driving end of the rotating motor 25 is fixedly connected to one end of the second pressing roller 14. Both ends of the first pressing roller 13 are connected to the threaded rod 30 through the connecting block 31. The threaded rod 30 is rotatably inserted into the connecting block 31. The two ends of the second pressing roller 14 and the first pressing roller 13 are connected together through the bracket 26 respectively. The first pressing roller 13 and the second pressing roller 14 are rotatably connected to one side of the bracket 26. The lower end of the threaded rod 30 threadedly passes through the middle position of the bracket 26. When it is necessary to adjust the relative distance between the first pressing roller 13, the second pressing roller 14, and the third pressing roller 15, rotating the threaded rod 30 can change the position relative to the bracket 26, and then change the height of the first pressing roller 13. The lower surface of the shaped roof panel is in contact with the second pressing roller 14 and the third pressing roller 15, and the upper surface of the roof panel is in contact with the first pressing roller 13. The second pressing roller 14 rotates under the action of the driving end of the rotating motor 25 to move the passing roof panel. Three points can determine a circle. The first pressing roller 13, the second pressing roller 14, and the third pressing roller 15 can draw a circle, thereby determining the curvature of the passing roof panel, and then bending the roof panel into the required shape. The second pressing roller 14 is rotatably installed on the bending frame 12, and the third pressing roller 15 is installed on the bending frame 12 through the bracket 26.

[0035] The installation mechanism includes an installation seat 18 and a clamping seat 19. The installation seat 18 is fixedly installed in the installation groove 16. The installation groove 16 is installed on the installation seat 18, and a rotating groove is formed between the two. The rotating shaft 9 passes through the rotating groove. One side of the clamping seat 19 is inserted into the installation seat 18 through the insertion shaft 20. On the surface of the clamping seat 19, clamping shafts 23 are symmetrically connected through the first elastic pieces 21. A limiting block 22 slidably connected to the clamping shaft 23 is fixedly installed on the clamping seat 19. The clamping shaft 23 is clamped in the installation groove 16. The disassembly on the first side wall 4 can be realized through the installation mechanism. Moving the clamping shaft 23 upward to compress the first elastic piece 21 can disengage the clamping shaft 23 from the installation groove 16, and then moving the clamping seat 19 to disengage the insertion shaft 20 from the installation seat 18, and then the clamping seat 19 can be taken off from above the installation seat 18, and the rotating shaft 9 can be disengaged from the first side wall 4 to achieve the disassembly function.

[0036] One end of each rotating shaft 9 is fixedly connected with a sprocket 34. A chain 33 is sleeved between two adjacent sprockets 34. A driving motor 32 is fixedly installed on the pressing frame 1. The driving end of the driving motor 32 is detachably clamped to the end of one of the rotating shafts 9. The driving motor 32 drives one of the rotating shafts 9 to rotate through the driving end. Two adjacent rotating shafts 9 are connected through the chain 33. Then when one rotating shaft 9 rotates, the remaining rotating shafts 9 can be driven to rotate, realizing the conveying and pressing effect of the roof panel.

[0037] A plurality of crawler wheels 3 are rotatably connected to the bottom of the pressing frame 1. A crawler 2 is sleeved on the surface of the crawler wheels 3. A plurality of rollers 24 are rotatably installed at the bottom of the bending frame 12. The rotation of the crawler wheels 3 drives the crawler 2 to move, thereby realizing the movement of the pressing frame 1. The rotation of the rollers 24 can drive the bending frame 12 to move. The pressing frame 1 and the bending frame 12 can be used separately for transportation or combined together for use, which is convenient for use at the construction site.

[0038] This equipment is directly transported to the construction site for use. Each rotating shaft 9 on the pressing frame 1 can be disassembled and transported in batches. The movable clamping shaft 23 disengages it from the installation groove 16, and the insertion shaft 20 is pulled out from the hole in the mounting seat 18, then the clamping seat 19 can be removed from the mounting seat 18, so that the rotating shaft 9 can be disengaged from the first side wall 4. The other end of the rotating shaft 9 is inserted through the second side wall 5, so that each rotating shaft 9 can be disassembled from the pressing frame 1 from one side of the second side wall 5. Then the rotating shaft 9 is separated from the pressing frame 1 and can be transported separately. One end of the second pressing roller 14 and the rotating motor 25 are detachably fixedly clamped, so that the second pressing roller 14 can be separated from the rotating motor 25. The first pressing roller 13, the second pressing roller 14, and the third pressing roller 15 are erected on the bending frame 12 through the bracket 26, and the adjusting mechanism 17 is separated from the bending frame 12 to achieve disassembly.

[0039] When pressing the roof panel, the roof panel is conveyed inward from the input end of the pressing frame 1. The two ends of the roof panel are respectively abutted against the V-shaped plates 28 on both sides, restricting the roof panel within the range where it is pressed by the first side wall 4 and the second side wall 5. The cylinder 29 can change the angle of the V-shaped plate 28 relative to the L-shaped shaft 27 by the telescopic movement of the driving end. The roof panel restricted by the two V-shaped plates 28 will be bent and deformed. The upper surface of the roof panel abuts against the two linkage shafts 10, and the second elastic piece 36 with elasticity is installed and connected, so as to control the deformed roof panel to pass smoothly under each rotating shaft 9.

[0040] The limiting wheels 6 at both ends of the rotating shaft 9 can press and limit the two end edges of the roof panel. With the rotation of each rotating shaft 9 for transporting the roof panel, and the mutual cooperation of the pressing wheel 7 and the rolling wheel 8, under the action of pressure, the rolling wheel 8 can press out the concave part of the roof, and the pressing wheel 7 can press out the convex part of the roof. Finally, the formed roof panel is output from the output end.

[0041] The roof surface has a certain curvature, and it is also necessary to bend the roof surface pressed into a straight line into a curved surface. The roof panel passes under the first extrusion roller 13 and above the second extrusion roller 14 and the third extrusion roller 15. The second extrusion roller 14 and the third extrusion roller 15 apply an upward pressure to the roof panel, and the first extrusion roller 13 applies a downward pressure to the roof panel. Thus, under the combined action of the first extrusion roller 13, the second extrusion roller 14, and the third extrusion roller 15, the passing roof panel is bent into a curved roof surface with a certain curvature.

[0042] The pressing and bending of the roof surface are directly carried out at the construction site, eliminating the transportation process of the roof precast slab. Thus, the damage of precast components can be effectively avoided. The reduction of unqualified precast components can reduce the consumption of materials. At the same time, this equipment is detachable, convenient for installation and transportation, and very convenient to use at the construction site.

[0043] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
