Description

Technical Field

[0001] The invention relates to the field of concrete removal, in particular to a steel-wood keel vibration concrete remover. Background Art

[0002] In the process of building cement construction, especially in the construction of bridges, high-speed railways, and elevated roads, a lot of reinforced cement is poured during construction. For the sake of safety and convenience, it is necessary to build a pouring template before pouring. When building a large-area template, more keels are needed to fix the position of the template and adjust the height of the plane. Keels are suitable for structures such as walls, columns, and roofs. They serve as the secondary back ribs in the template support system to replace traditional wooden structures.

[0003] 1. It is used as a secondary keel in the building horizontal structure formwork system, and can also be used in beam, wall and column formwork projects.

[0004] 2. Infrastructure such as bridges, subways, aircraft factories, high-speed rail stations, etc.: Steel-clad wooden keels are used as supporting structures in these projects to improve project quality and efficiency.

[0005] 3. Factory buildings and other construction projects Due to its high strength and flatness, steel-clad wood keels also play an important role in these projects, improving the quality of concrete molding and meeting the requirements of plain concrete. 4. Environmentally friendly and cost-effective: The use of steel-clad wooden keels not only saves wood, reduces comprehensive energy consumption and costs, but also has a much higher turnover rate than traditional wooden beams, thereby reducing project costs.

[0006] Before the steel-clad wooden keel is reused, the steel nails on the surface of the keel need to be removed, the whole keel needs to be straightened and the residual cement on the surface needs to be cleaned. At present, due to the lack of special equipment, the steel nails need to be removed manually, and the surface of the keel needs to be knocked with a steel hammer and cleaned with a wire brush. A section of the steel-clad wooden keel is manually inserted into a steel frame pre-buried at the work site with a gap larger than the keel cross-section. A section of the keel is manually inserted into the gap to pry the keel apart. The operator uses his eyes to check whether the keel edge is in a straight line and makes vertical corrections to the keel.

[0022] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figures 1 to 9 A steel-wood keel vibration concrete removal machine comprises a chassis 1, one side of which is sequentially mounted with three groups of straightening and pressing wheel groups 2, a concrete removal knocking assembly 3 and a polishing and slag removal assembly 4, wherein the components cooperate with each other to jointly complete the correction and cleaning tasks of the steel-wood keel; The straightening roller assembly 2 includes a lower roller 22 rotatably connected to the outer side of the chassis 1 through a first rotating shaft 21, and an upper roller 23 arranged above the lower roller 22 and cooperating therewith. A second rotating shaft 24 is fixed to the center of the upper roller 23, and a first connecting block 25 is fixed to the middle of the second rotating shaft 24. A first screw hand wheel 26 is rotatably connected to the first connecting block 25. The hand wheel is threadedly connected to the chassis 1, so that the upper roller 23 can move up and down to adjust the distance between the upper roller 23 and the lower roller 22. A driving device a is also installed on the chassis 1, which can drive the second rotating shaft 24 and the first rotating shaft 21 to rotate simultaneously, so as to realize the correction of the steel-wood keel and its forward conveyance. When the steel-wood keel is severely deformed or the concrete layer is too thick to be conveyed forward, the distance between the upper roller 23 and the lower roller 22 can be adjusted, and the steel-wood keel can even be taken out.

[0024] The driving device a can drive the second rotating shaft 24 and the first rotating shaft 21 to rotate together, which can not only realize the correction of the steel-wood keel, but also realize forward transportation. By rotating the first connecting block 25, the first connecting block 25, the second rotating shaft 24 and the upper pressing wheel 23 can be driven up and down together, and the distance between the upper pressing wheel 23 and the lower pressing wheel 22 can be adjusted. When the steel-wood keel cannot be transported forward due to severe deformation of the steel-wood keel or the concrete is thick, the steel-wood keel can be taken out.

[0025] The driving mechanism a includes a straightening motor 5 fixed on the chassis 1, and a driving pulley 51 is fixed on its output shaft. A first driving gear 52 and a driven pulley 53 are fixed on the first rotating shaft 21 near the feed end of the concrete remover, and the driven pulley 53 is connected to the driving pulley 51 through a belt b. At the same time, a first driven gear 54 meshing with the first driving gear 52 is fixed on the second rotating shaft 24 near the feed end. A first sprocket 55 is fixed on all first rotating shafts 21 and is connected through a first chain c; a second sprocket 56 is fixed on all second rotating shafts 24 and is connected through a second chain d. This design ensures that all lower pressure wheels 22 and upper pressure wheels 23 can rotate synchronously.

[0026] The driving pulley 51 is driven to rotate by the straightening motor 5, and one of the first rotating shafts 21 and the first driving gear 52 is driven to rotate by the belt b. Since the first driving gear 52 is meshed and connected with the first driven gear 54, the second rotating shaft 24 will also rotate. Combined with the setting of the first chain c and the second chain d, all the second rotating shafts 24 and the first rotating shaft 21 will rotate, that is, all the lower pressure wheels 22 and the upper pressure wheels 23 will rotate together.

[0027] The straightening wheel group 2 has the same shape in all parts. The opening angle of the lower pressing wheel 22 and the upper pressing wheel 23 of the first group of straightening wheel groups 2 is greater than 90 degrees (flattening the keel in the upper and lower directions of the square end face), the opening angle of the lower pressing wheel 22 and the upper pressing wheel 23 of the second group of straightening wheel groups 2 is less than 90 degrees (lengthening the keel in the upper and lower directions of the square end face), and the opening angle of the lower pressing wheel 22 and the upper pressing wheel 23 of the third group of straightening wheel groups 2 is equal to 90 degrees (making the keel end face return to a square shape).

[0028] When the square steel on the surface of the keel is deformed by external pressure, the cement residue attached to the surface of the square steel is very easy to fall off after being squeezed and deformed (the adhesion of cement is less than 10MPa) due to the large difference between the elastic modulus of steel (greater than 200GPa) and the elastic modulus of cement (20GPa). The cement residue squeezed between the upper pressing wheel 23 and the upper pressing wheel 23 and the steel pipe will be squeezed into powder and fall off (the Poisson's ratio of cement is generally 0.2).

[0029] The concrete removal knocking assembly 3 includes a concrete removal motor 31 fixed to the top of the chassis 1, a cam 32 is fixed to the output end of the concrete removal motor 31, two ear plates 33 are fixed to the chassis 1, a fixed shaft 34 is fixed between the two ear plates 33, a coil spring 35 is installed on the fixed shaft 34, a U-shaped fork 36 is fixed to one end of the coil spring 35, the cam 32 cooperates with the inner wall of the U-shaped fork 36, and a U-shaped knocking block 37 is fixed to the other end of the coil spring 35, and the inner wall of the U-shaped knocking block 37 is provided with a V-shaped groove 38 that cooperates with the corners of the steel-wood keel.

[0030] The polishing and slag removal component 4 includes a driving shaft 41 and a driven shaft 42 rotatably connected to the chassis 1, and the driving shaft 41 and the driven shaft 42 are both equipped with mutually matching wire slag removal wheels 43, and the driving shaft 41 and the driven shaft 42 are respectively equipped with a second driving gear 44 and a second driven gear 45, and the second driving gear 44 and the second driven gear 45 are meshingly connected, and a polishing and slag removal motor 46 is fixed on the top of the chassis 1, and the output shaft of the polishing and slag removal motor 46 is fixedly connected to one end of the driving shaft 41.

[0031] The polishing slag removal motor 46 drives the driving shaft 41 to rotate, and then drives the driven shaft 42 to rotate, and the two steel wire slag removal wheels 43 rotate, and the cement residues scraped off by the steel wire slag removal wheels 43 will fall to the ground below.

[0032] It also includes a lifting and limiting wheel group 6 arranged at one end of the chassis 1 for supporting the steel-wood keel, the lifting and limiting wheel group 6 includes a lower lifting wheel 62 rotatably connected to the chassis 1 through a third rotating shaft 61 and an upper lifting wheel 63 arranged above the lower lifting wheel 62 and cooperating with the lower lifting wheel 62, a fourth rotating shaft 64 is fixed at the center of the upper lifting wheel 63, a second connecting block 65 is fixed on the fourth rotating shaft 64, a second screw handwheel 66 is rotatably connected to the second connecting block 65, and the second screw handwheel 66 is connected to the chassis 1 through a threaded connection.

[0033] The gap between the upper pressing wheel 23 and the lower pressing wheel 22, the connection between the two steel wire slag removal wheels 43, and the gap between the lower lifting wheel 62 and the upper lifting wheel 63 are on the same straight line, so that the correction effect of the steel-wood keel is better.

[0034] Universal self-locking wheels 7 are installed at the four corners of the bottom of the chassis 1 to facilitate the movement of the chassis 1.

[0035] The summary principle of this steel-wood keel vibration concrete removal machine is as follows: Straightening roller set 2: The three straightening pressure wheel groups 2 drive the lower pressure wheel 22 and the upper pressure wheel 23 to rotate respectively through the first rotating shaft 21 and the second rotating shaft 24.

[0036] The first set of straightening rollers 2 (opening angle > 90°) flattens the keel, the second set (opening angle < 90°) lengthens it, and the third set (opening angle = 90°) restores it to a square shape to achieve straightening.

[0037] The driving device a (including the straightening motor 5, the driving pulley 51, the driven pulley 53, the first driving gear 52, the first driven gear 54, the first sprocket 55, the second sprocket 56, etc.) is driven by the belt b, the first chain c and the second chain d to synchronously drive each straightening pressure wheel group 2.

[0038] Concrete knocking component 3: The concrete removing motor 31 drives the cam 32 to rotate.

[0039] The cam 32 cooperates with the U-shaped fork 36 to make the coil spring 35 swing along the fixed shaft 34, and the swinging speed is not fixed, simulating knocking, and the setting of the coil spring 35 can meet the needs of removing concrete of different thicknesses. When the concrete is thicker, the coil spring 35 will deform. The V-shaped groove 38 on the inner wall of the U-shaped knocking block 37 cooperates with the corners of the keel to achieve concrete removal.

[0040] Polishing and slag removal component 4: The polishing and slag removal motor 46 drives the driving shaft 41 to rotate.

[0041] The steel wire slag removal wheel 43 on the driving shaft 41 cooperates with the steel wire slag removal wheel 43 on the driven shaft 42 to polish and remove slag from the keel.

[0042] The second driving gear 44 and the second driven gear 45 are meshed with each other to ensure that the driving shaft 41 and the driven shaft 42 rotate synchronously.

[0043] Lifting limit wheel set 6: The lower lifting wheel 62 and the upper lifting wheel 63 support and guide the keel to move out through the third rotating shaft 61 and the fourth rotating shaft 64 .

[0044] detail: 1. Before starting, the manager should go to the site in person to evaluate the availability of the old keel.

[0045] Clarify the cleaning ideas and stacking locations to avoid duplication of work.

[0046] 2. First, pull out the nails manually, and then pull out the nails on the old formwork at the designated unified stacking location.

[0047] 3. Processing: The old steel-clad wooden keels after the nails have been pulled out will be processed centrally at the designated location according to the usage specifications.

[0048] Move the steel-clad wood keel surface treatment device to the processing site, and manually insert the steel-clad wood keel with cement and bend on the surface into the equipment from the insertion end of the steel-clad wood keel vibration concrete removal machine. Through the extrusion and deformation of the steel-clad wood keel bracket surface and the vibration knocking and wire wheel rotation flushing at the back, the treated steel-clad wood keel is automatically sent out from the rear end of the equipment, and manually placed the treated steel-clad wood keel into the pre-placed storage rack, and then stacked, bundled and transported to the construction site.

[0049] 4. Classification: The processed old templates are classified and stacked for easy use. Through the above steps, not only can the reuse of the keel be ensured, but also the service life of the keel can be effectively extended, waste can be reduced, and the material use and management work in the construction process can be optimized.
