Description

Technical Field

[0001] This invention belongs to the field of protective layer pad installation technology, specifically a protective layer pad fixing device. Background Technology

[0002] Reinforcing steel cover spacers are placed under beams in brick-concrete structures to increase the bearing area, a common method for addressing localized load-bearing situations. The thickness of the concrete cover for reinforcing steel affects the structure's load-bearing capacity, durability, and fire resistance. Its primary function is to withstand external forces. The cover provides anchorage force to the reinforcing steel, and through this anchorage force between the concrete and the steel, the two work together in a tight bond. When the cover is too thin or missing, its anchorage force is reduced, thus decreasing the structure's resistance to axial forces and bending moments.

[0003] When fixing existing protective layer blocks, especially when the protective layer blocks are made of concrete, the concrete blocks need to have pre-reserved openings. Personnel need to hold the concrete blocks and insert them one by one into the reinforcing bars, then rotate the position of the blocks to turn the openings to the outside, and finally insert the fixing blocks into the openings to ensure that the concrete blocks do not fall off, thus completing the installation of the concrete blocks.

[0004] In the aforementioned prior art, when using concrete spacers, personnel need to insert each spacer into the reinforcing bar one by one. Moreover, after the concrete spacer is installed, personnel must manually rotate the spacer to adjust the opening direction before installing the fixing blocks to fix the concrete spacer to the reinforcing bar. This is not only time-consuming and laborious, but also greatly affects the installation efficiency of the spacers and slows down the progress of the entire project.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The protective layer pad fixing device of the present invention, by starting the drive motor to rotate the screw thread transmission slider, and the slider drives the rotating block and the triangular push block to slide in the limiting groove cavity to move to the right, thereby causing the triangular push block to push the lowest pad body in the guide rail cavity to move, so that the pad body is accurately inserted into the outside of the rebar; after the lowest pad body separates from the next lowest pad body, the next lowest pad body falls to the pre-installation position, which is convenient for pushing and conveying the pad body again for installation, realizing the rapid feeding and installation of concrete pads in a cycle; it eliminates the need for personnel to insert concrete pads into the rebar one by one, realizes automatic feeding, reduces manual handling work, greatly improves work efficiency, and reduces labor.

[0019] 2.

[0020] 3. The protective layer pad fixing device of the present invention, by starting the servo motor to rotate the pulley 1, the pulley rotates the transmission wheel through the first belt and the second belt.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-10 The present invention provides a technical solution:

[0036] A protective layer pad fixing device includes a mounting base 1. A drive wheel 2 is provided on the upper end face of the mounting base 1. Several support blocks 9 are fixedly connected to the left edge of the upper end face of the mounting base 1, and a support plate 3 is fixedly connected to the upper end face of the support blocks 9. A U-shaped fixing bracket 7 is fixedly connected to the right end face of the support plate 3. A drive motor 10 is fixedly connected to the left end face of the support blocks 9. A lead screw 11 is fixedly connected to the drive motor 10 through an output shaft. A slider 31 is externally threaded to the lead screw 11. The slider 31 has rotating grooves 32 at both its front and rear ends. The front and rear ends of block 31 are rotatably connected to cylinders 34 via bearings. A fixed disk 35 is fixedly connected to the outside of cylinder 34 located in the inner cavity of rotating groove 32. A torsion spring 33 is fixedly connected to the bottom end of fixed disk 35 and inner cavity of rotating groove 32. A second abutment block 38 is fixedly connected to the outside of cylinder 34 located at one end of inner cavity of rotating groove 32. A first abutment block 37 is fixedly connected to the inner wall of rotating groove 32. A rotating block 36 is fixedly connected to the end of cylinder 34 away from slider 31. A triangular push block 42 is fixedly connected to the upper surface of rotating block 36.

[0037] A feed inlet 4 is provided at the upper left edge of the support plate 3, and a limiting guide frame 5 is fixedly connected to the inner wall of the feed inlet 4. A guide rail 12 is provided inside the support plate 3, and a limiting groove 40 is provided at the bottom of the inner cavity of the guide rail 12.

[0038] Specifically, first, insert the U-shaped fixing bracket 7 into both sides of the rebar to be fixed. Then, start the drive motor 10 to rotate the screw 11, which drives the slider 31 via a threaded connection. The slider 31, using the cylinder 34, drives the rotating block 36 and the triangular pushing block 42 to slide to the right within the limiting groove 40. This causes the triangular pushing block 42 to push the lowest pad block 6 within the guide rail 12. The triangular pushing blocks 42 are tapered at their closest points, and this tapered shape increases friction with the pad block 6, preventing rotation of the pad block 6 while it is being pushed. This ensures the pad block 6 is accurately inserted into the rebar. After the lowest pad block 6 separates from the next lowest pad block 6, the next lowest pad block 6 falls to its pre-installed position. After the pad block 6 is inserted, control the screw 11 to rotate in the opposite direction, causing the slider 31 to move and reset. The slider 31, using the cylinder 34, drives the rotating block 36 and the triangular pushing block 42 to slide to the right within the limiting groove 40. 2. Moving to the left, the inclined surface of the triangular push block 42 contacts the pre-installed pad block body 6. The triangular push block 42 drives the rotating block 36 to rotate the cylinder 34, and the cylinder 34 is rotated by the torsion spring 33 through the fixed plate 35. This causes the triangular push block 42 to move to the left from under the pad block body 6. When it reaches the left edge of the limiting groove 40, the triangular push block 42 is no longer limited by the pad block body 6. The elastic force of the torsion spring 33 drives the fixed plate 35 to rotate the cylinder 34 to reset. At the same time, the cylinder 34 is held in place by the second abutment block 38 and the first abutment block 37, so that the cylinder 34 drives the rotating block 36 to rotate. The triangular push block 42 always remains in a vertical state, which is convenient for pushing and conveying the pad block body 6 again. This realizes the rapid feeding and installation of concrete pad blocks in a cycle. It eliminates the need for personnel to insert the concrete pad blocks into the steel bars one by one. It can realize automatic feeding, reduce personnel handling work, greatly improve work efficiency, and reduce labor.

[0039] A fixing block 13 is fixedly connected to the right edge of the lower end face of the support plate 3. The fixing block 13 is rotatably connected to the lead screw 11 through a bearing. A semi-circular limiting block 41 is fixedly connected to the left edge of the inner cavity of the guide rail 12.

[0040] Specifically, the personnel install the pad block body 6 on the outside of the limiting guide frame 5 in sequence, so that the pad block body 6, together with the feed port 4 and the semi-circular limiting block 41, falls smoothly into the inner cavity of the guide rail 12 through the limiting guide frame 5. Moreover, when the pad block body 6 is pushed out below the feed port 4 by the triangular pushing block 42, the pad block body 6 outside the limiting guide frame 5 falls back into the inner cavity of the guide rail 12 through the feed port 4, thereby realizing the rapid replenishment of concrete pad blocks.

[0041] like Figure 4 and Figure 5 As shown, a fixed plate 35 is fixedly connected to the outside of the cylinder 34 located in the inner cavity of the rotating groove 32. A torsion spring 33 is fixedly connected to the bottom end of the fixed plate 35 and the inner cavity of the rotating groove 32. A second abutment block 38 is fixedly connected to the outside of the cylinder 34 located at one end of the inner cavity of the rotating groove 32. A first abutment block 37 is fixedly connected to the inner wall of the rotating groove 32. The first abutment block 37 and the second abutment block 38 abut against each other to prevent the triangular push block 42 from rotating. At the same time, the triangular push block 42 is used to push the concrete pad block for material loading and installation.

[0042] like Figures 6 to 8 As shown, a transmission assembly is provided on the upper surface of the U-shaped fixing frame 7. The transmission assembly includes a rotating disk 23, which drives the concrete pad block to rotate and adjust the angle. A transmission groove 27 is provided on the upper right side of the U-shaped fixing frame 7. A servo motor is provided in the bottom of the inner cavity of the transmission groove 27. The servo motor is fixedly connected to a pulley 14 through an output shaft. The pulley 14 is connected to a transmission wheel 25 through a first belt 26 and a second belt 29. Tooth blocks 30 are evenly arranged on the outside of the transmission wheel 25. The transmission wheel 25 is rotatably connected to the U-shaped fixing frame 7 through a bearing. The transmission wheel 25 is connected to a sprocket 24 through the tooth blocks 30 and a chain 28. Through grooves 22 are provided on the front and rear walls of the inner cavity of the U-shaped fixing frame 7. Four support columns 39 are rotatably connected to the inner cavity of the through grooves 22 through bearings. The rotating disk 23 is fixedly connected to the outside of one end of the four support columns 39 in the inner cavity of the through grooves 22. The rotating disk 23 is provided with a latex anti-slip layer on the outside. The sprocket 24 is fixedly connected to the upper surface of the four support columns 39.

[0043] Specifically, by starting the servo motor to rotate the pulley 14, the pulley 14 rotates the transmission wheel 25 via the first belt 26 and the second belt 29. At the same time, the transmission wheel 25 drives the sprocket 24 to rotate the support column 39 via the external toothed block 30 and the transmission chain 28. In turn, the support column 39 drives the rotating disk 23 during rotation. The rotating disk 23 is provided with a latex anti-slip layer. During the rotation of the rotating disk 23, the latex anti-slip layer drives the pad block body 6 to rotate and adjust the angle, thereby realizing the automatic rotation adjustment of the opening angle of the concrete pad block.

[0044] like Figure 7 and Figure 10As shown, a guide cylinder 8 is fixedly connected to the upper end face of the U-shaped fixing frame 7. A feeding assembly is provided at the lower left end of the guide cylinder 8. The feeding assembly includes a triangular insert 19 and a trapezoidal pressing block 20. The fixed insert is fed and the concrete pad is pressed and installed by driving the triangular insert 19 and the trapezoidal pressing block 20. Two sliding grooves 21 are provided at the lower left end face of the guide cylinder 8. The triangular insert 19 and the trapezoidal pressing block 20 are slidably connected in the inner cavity of the two sliding grooves 21 respectively. The left end face of the triangular insert 19 and the trapezoidal pressing block 20 A connecting block 18 is fixedly connected. A U-shaped support block 16 is fixedly connected to the lower left end face of the guide cylinder 8. A swing rod 15 is rotatably connected to the inner cavity of the U-shaped support block 16 through a bearing. A micro motor is fixedly connected to the rear end face of the U-shaped support block 16, and the micro motor is fixedly connected to the swing rod 15 through an output shaft. A first pull rod 17 and a second pull rod 43 are rotatably connected to both ends of the swing rod 15 through a rotating shaft. The end of the first pull rod 17 and the second pull rod 43 away from the swing rod 15 is rotatably connected to the connecting block 18 through a rotating shaft.

[0045] Specifically, by starting the micro motor, the swing rod 15 swings within the U-shaped support block 16, causing one end of the swing rod 15 to pull the first pull rod 17 via a rotating shaft. The first pull rod 17, in turn, pulls the connecting block 18 via the rotating shaft, causing the trapezoidal pressing block 20 to slide out of the guide cylinder 8. Simultaneously, the other end of the swing rod 15 pushes the second pull rod 43 via the rotating shaft, causing the second pull rod 43 to push the connecting block 18 via the rotating shaft, thus inserting the triangular insert 19 into the guide cylinder 8. The triangular insert 19 is then inserted between the fixed inserts, restraining and limiting the fixed inserts. The fixed insert at the lower edge of the guide cylinder 8... As the trapezoidal pressing block 20 is retracted, the insert falls into the opening of the pad body 6. Then, the swing rod 15 rotates again to push the first pull rod 17, which in turn drives the connecting block 18 and the trapezoidal pressing block 20 into the inner cavity of the guide cylinder 8. The trapezoidal pressing block 20 uses its inclined surface to press the fixed insert in the opening of the pad body 6, so that the fixed insert fixes the pad body 6. When the swing rod 15 pulls the second pull rod 43, which causes the connecting block 18 and the triangular insert 19 to slide out of the inner cavity of the guide cylinder 8, the fixed insert in the inner cavity of the guide cylinder 8 falls onto the trapezoidal pressing block 20 again, thus realizing the cyclic feeding and installation of the fixed insert.

[0046] Working principle: The drive wheel 2 drives the mounting base 1 to move the support block 9, which in turn drives the support plate 3 to push the U-shaped fixing frame 7 into the middle of the rebar, thereby improving the accuracy of the pad body 6 being inserted into the outside of the rebar. At the same time, the personnel install the pad body 6 sequentially outside the limiting guide frame 5, so that the pad body 6, through the limiting guide frame 5, cooperates with the feed port 4 and the semi-circular limiting block 41 to fall smoothly into the inner cavity of the guide rail 12. At the same time, the personnel start the drive motor 10 to rotate the screw 11 to drive the slider 31, and the slider 31, through the cylinder 34, drives the rotating block 36 and the triangular push block 42 to slide in the inner cavity of the limiting groove 40 to move to the right, thereby causing the triangular push block 42 to push the guide rail 12. 2. The pad body 6 in the inner cavity moves, while the triangular push blocks 42 are provided with cones at their close proximity. The cones contact the pad body 6 to increase the friction during pushing, preventing the pad body 6 from rotating when the triangular push blocks 42 push the pad body 6 to move. This allows the pad body 6 to be accurately inserted into the outside of the steel bar. Moreover, when the pad body 6 is pushed out below the feed port 4 by the triangular push blocks 42, the pad body 6 outside the limiting guide frame 5 falls back into the inner cavity of the guide rail 12 through the feed port 4. This realizes the cyclic conveying of concrete pads and ensures the rapid replenishment of concrete pads. At the same time, it avoids the trouble of manual labor being unable to carry a large number of concrete pads for installation and use.

[0047] When the screw 11 drives the slider 31 to move and reset, the slider 31 uses the cylinder 34 to drive the rotating block 36 and the triangular push block 42 to move to the left. After the triangular push block 42 contacts the pad body 6 with its inclined surface, the triangular push block 42 will drive the rotating block 36 to rotate the cylinder 34. At the same time, the cylinder 34 uses the fixed plate 35 to twist the torsion spring 33 to flip to the right, thereby causing the triangular push block 42 to move to the left from under the pad body 6. When it moves to the left edge of the limiting groove 40, the triangular push block 42 is no longer limited by the pad body 6. The torsion spring 33 twists the fixed plate 35 to drive the cylinder 34 to flip and reset to the left. At the same time, the cylinder 34 is held in place by the second abutment 38 and the first abutment 37. Then, the cylinder 34 drives the rotating block 36 to rotate the triangular push block 42 to always keep it in a vertical state, thereby pushing and conveying the pad body 6 again, realizing the inefficiency of manual installation of concrete pads.

[0048] Then, the operator starts the servo motor to rotate pulley 14, which in turn rotates transmission wheel 25 via first belt 26 and second belt 29. Simultaneously, transmission wheel 25, via external toothed block 30, drives chain 28 to rotate sprocket 24 and support column 39. This rotation of support column 39 then drives rotating disk 23. Rotating disk 23 has a latex anti-slip layer on its exterior, allowing the latex anti-slip layer to drive the rotation of pad block body 6 during rotation, thus avoiding the inefficiency of manually adjusting the opening angle of the concrete pad block. After adjusting the opening angle of the concrete pad block, the operator starts the micro motor to rotate swing rod 15 within the U-shaped support block 16. One end of swing rod 15 pulls first pull rod 17 via a rotating shaft, which in turn pulls connecting block 18, causing trapezoidal pressing block 20 to slide out of the guide cylinder 8. 5. The other end uses a rotating shaft to push the second pull rod 43, and the second pull rod 43 uses the rotating shaft to push the connecting block 18 to drive the triangular plug 19 into the inner cavity of the guide cylinder 8. At the same time, the triangular plug 19 is inserted between the fixed plugs to hold and limit the fixed plugs. The fixed plug at the lower edge of the inner cavity of the guide cylinder 8 falls into the opening of the pad body 6 as the trapezoidal pressing block 20 is retracted. Then, the swing rod 15 rotates again to push the first pull rod 17 to drive the connecting block 18 and the trapezoidal pressing block 20 into the inner cavity of the guide cylinder 8. The trapezoidal pressing block 20 uses its inclined surface to press the fixed plug in the opening of the pad body 6, so that the fixed plug fixes the pad body 6. When the swing rod 15 pulls the second pull rod 43 to drive the connecting block 18 and the triangular plug 19 out of the inner cavity of the guide cylinder 8, the fixed plug in the inner cavity of the guide cylinder 8 falls onto the trapezoidal pressing block 20 again, thus solving the problem of low efficiency of manual installation of fixed plugs.
