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] During the construction of concrete structures, especially bridges, high-speed railways, and elevated highways, a large amount of reinforced concrete is poured. For safety and convenience, it is necessary to construct a pouring formwork before pouring. When constructing large-scale formwork, a large number of keels are required to fix the formwork in place and adjust the height of the surface. Keels are used in structures such as walls, columns, and roofs, serving as the secondary back ribs in the formwork support system, replacing traditional wooden beams.

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

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

[0005] 3. Factory buildings and other construction projects

[0006] 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.

[0007] 4. Environmentally friendly and cost-effective:

[0008] The use of steel-clad wooden keels not only saves wood and reduces comprehensive energy consumption and costs, but also has a turnover rate far higher than traditional wooden beams, thereby reducing project costs.

[0009] Before reusing the steel-clad wooden keel, the surface steel nails need to be removed, the entire 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 hit 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. The keel section 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.

DETAILED DESCRIPTION

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] Please refer to Figures 1 to 9 A steel-wood keel vibration concrete removal machine includes a chassis 1, one side of which is sequentially mounted with three sets of straightening and pressing wheel assemblies 2, a concrete removal knocking assembly 3, and a polishing and slag removal assembly 4. The components cooperate with each other to jointly complete the correction and cleaning tasks of the steel-wood keel;

[0036] The straightening roller assembly 2 includes a lower roller 22 that is rotatably connected to the outside of the chassis 1 via a first rotating shaft 21, and an upper roller 23 that is arranged above the lower roller 22 and cooperates with it. 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 handwheel 26 is rotatably connected to the first connecting block 25. The handwheel is threadedly connected to the chassis 1, allowing the upper roller 23 to move up and down to adjust the distance between it 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, thereby achieving both 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, or even the steel-wood keel can be removed.

[0037] 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.

[0038] The drive device a includes a straightening motor 5 fixed to the chassis 1, whose output shaft is fixed with a driving pulley 51. A first driving gear 52 and a driven pulley 53 are fixed to the first rotating shaft 21 near the feed end of the concrete remover. The driven pulley 53 is connected to the driving pulley 51 via a belt b. Simultaneously, a first driven gear 54 is fixed to the second rotating shaft 24 near the feed end, which meshes with the first driving gear 52. A first sprocket is fixed to all first rotating shafts 21 and connected via a first chain c; a second sprocket is fixed to all second rotating shafts 24 and connected via a second chain d. This design ensures that all lower and upper pressure wheels 22 and 23 can rotate synchronously.

[0039] 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.

[0040] The shapes of the straightening roller groups 2 are different. The opening angle of the lower pressing wheel 22 and the upper pressing wheel 23 of the first group of straightening roller 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 roller 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 roller groups 2 is equal to 90 degrees (making the keel end face return to a square shape).

[0041] 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 due to the large difference between the elastic modulus of steel (greater than 200GPa) and the elastic modulus of cement (20GPa) (the adhesion force of cement is less than 10MPa). 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).

[0042] 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, one end of the coil spring 35 is fixed with a U-shaped fork 36, the cam 32 cooperates with the inner wall of the U-shaped fork 36, and the other end of the coil spring 35 is fixed with a U-shaped knocking block 37, and the inner wall of the U-shaped knocking block 37 is provided with a V-shaped groove 38 that cooperates with the edge corners of the steel-wood keel.

[0043] The polishing and slag removal assembly 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 cooperating wire slag removal wheels 43. 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 meshed and connected. 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.

[0044] 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 wire slag removal wheels 43 rotate, and the cement residues scraped off by the wire slag removal wheels 43 will fall to the ground below.

[0045] 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 threadedly connected to the chassis 1.

[0046] The gap between the upper pressing wheel 23 and the lower pressing wheel 22, the connection between the two 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.

[0047] 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.

[0048] The summary principle of this steel-wood keel vibration concrete remover is as follows:

[0049] Straightening roller set 2:

[0050] The three straightening roller groups 2 drive the lower pressing wheel 22 and the upper pressing wheel 23 to rotate respectively through the first rotating shaft 21 and the second rotating shaft 24 .

[0051] The first set of straightening rollers 2 (opening angle > 90°) flattens the keel, the second set (opening angle < 90°) stretches it, and the third set (opening angle = 90°) restores it to a square shape to achieve straightening.

[0052] 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, the second sprocket, 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.

[0053] Concrete removal striking component 3:

[0054] The concrete removing motor 31 drives the cam 32 to rotate.

[0055] The cam 32 cooperates with the U-shaped shift fork 36 to make the coil spring 35 swing along the fixed axis 34. The swinging speed is not fixed, simulating knocking. Moreover, the setting of the coil spring 35 can meet the needs of removing concrete of different thicknesses. When the concrete is thick, 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.

[0056] Polishing and slag removal component 4:

[0057] The polishing and slag removal motor 46 drives the driving shaft 41 to rotate.

[0058] 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.

[0059] The second driving gear 44 and the second driven gear 45 are engaged with each other to ensure that the driving shaft 41 and the driven shaft 42 rotate synchronously.

[0060] Lifting limit wheel set 6:

[0061] 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.

[0062] detail:

[0063] 1. Before starting, the management personnel should go to the site in person to evaluate the availability of old keels and clarify the cleaning ideas and stacking locations to avoid duplication of work.

[0064] 2. First, manually pull out the nails, and pull out the nails on the old formwork at a designated unified stacking location.

[0065] 3. Processing:

[0066] The old steel-clad wooden keels after the nails have been pulled out will be processed centrally at a designated location according to the usage specifications.

[0067] Move the surface treatment device of the steel-clad wood keel to the processing site, and manually insert the steel-clad wood keel with cement and bending 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 surface of the steel-clad wood keel bracket and the subsequent vibration knocking and wire wheel rotation flushing, 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 a pre-placed storage rack, and then stacked, bundled and transported to the construction site.

[0068] 4. Classification:

[0069] The processed old formwork is classified and stacked for easy reuse. Through the above steps, not only can the reuse of the keel be ensured, but the service life of the keel can also be effectively extended, waste can be reduced, and the use and management of materials in the construction process can be optimized.
