Abstract
Description
Technical Field
[0001] This invention relates to the field of concrete processing technology, and in particular to a concrete surface roughening device. Background Technology
[0002] In building construction, especially when working with existing concrete sections, the bonding between new and old concrete is a common practical problem in modern construction engineering. For example, bonding new concrete or tiles to old concrete. Whether the new and old concrete can work together depends primarily on their bonding properties. The quality of the bonding between new and old concrete is affected by many factors, such as the roughness of the interface, the type of bonding agent, the strength of the new and old concrete, and the orientation of the reinforcement interface. Among these, the roughness of the old concrete bonding surface, i.e., the quality of the concrete interface roughening, is of great significance to the quality of the bonding and reinforcement project. Roughening concrete components is a very common process. Roughening involves using serrated tools to create pits on the concrete surface, making it rough, as if covered with burrs.
[0003] Currently, roughening mainly involves workers using hand-held hammering tools to chisel out pits on the concrete surface. This method is difficult to guarantee in terms of quality and is inefficient. In particular, for the surfaces of some tall buildings, workers need to be suspended during the process, which is extremely dangerous. Summary of the Invention
[0004] To address the current problem of inconvenient surface roughening of concrete, this invention proposes a concrete surface roughening device to achieve mechanized roughening.
[0005] The technical solution adopted in this invention is to design a concrete surface roughening device, including a plate with roughening teeth, and a track arranged relative to the concrete surface. The plate is mounted on a traveling device via a telescopic device, the traveling device can move along the track, and the telescopic device controls the plate to move toward the concrete surface.
[0006] In some embodiments, two plates are arranged along the track direction, and the telescopic devices of the two plates are connected by a spacing adjustment device to form a movable chiseling module. The spacing adjustment device controls the distance between the two plates.
[0007] In some embodiments, the spacing adjustment device of two side-by-side movable chiseling modules is fixedly connected by a bracket.
[0008] In some implementations, each movable chiseling module moves along a different track.
[0009] In some embodiments, the concrete surface is a vertical surface, the track is a guide cable arranged parallel to the concrete surface, and the walking device includes two walking wheels that hold the guide cable, one of which is controlled to rotate by a power device.
[0010] In some embodiments, the two ends of the guide cable are fixed relative to the concrete surface by a height adjustment device.
[0011] In some embodiments, the track is a guide cable arranged parallel to the concrete surface, and the traveling device includes two traveling wheels that hold the guide cable, the traveling wheels being controlled by a traction rope to move along the track.
[0012] In some embodiments, each tooth of the chisel teeth is disposed within a guide cylinder, and the chisel teeth are controlled to extend and retract by a solenoid valve.
[0013] In some embodiments, a suction cup device for adsorbing concrete walls is also included, which is fixed relative to the plate body, and the suction cup of the suction cup device is controlled by a telescopic mechanism to move relative to the concrete wall.
[0014] In some embodiments, the suction cup is located in front of the plate.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] This invention utilizes a walking device to move the plate along the track, thereby continuously roughening the concrete surface. The telescopic device can be, for example, a pneumatic cylinder, hydraulic cylinder, or electric cylinder, or a similarly controlled telescopic device.
[0017] The traveling wheels of the present invention are mounted on the telescopic device and supported between the guide cable and the plate, ensuring that the plate faces the concrete surface, thereby roughening the concrete surface from bottom to top.
[0018] The present invention achieves the movement of the movable roughening module relative to the concrete surface along the guide cable by means of the telescopic cooperation between the spacing adjustment device and the telescopic device. Attached Figure Description

[0029] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments, and the following embodiments do not limit the invention covered by the claims. Furthermore, not all combinations of the features described in the embodiments are necessary for the inventive solution.
[0030] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0031] Example 1:
[0032] like Figure 1 , 2As shown, a concrete surface roughening device includes a plate 1 with roughening teeth 2 and a track positioned relative to the concrete surface 7. The plate 1 is mounted on a traveling device via a telescopic device 3, which moves along the track. The telescopic device 3 controls the plate 1 to move towards the concrete surface 7, thereby creating or pressing out pits on the concrete surface 7 to increase its roughness. The traveling device drives the plate 1 to move along the track, continuously roughening the concrete surface 7. The telescopic device 3 can be, for example, a pneumatic cylinder, hydraulic cylinder, or electric cylinder, and is controlled by an on / off mechanism.
[0033] Specifically, such as Figure 3 , 4 As shown, in this embodiment, the concrete surface 7 is a vertical surface, such as the facade of a building. The track consists of a guide cable 4 arranged parallel to the concrete surface 7. The upper end of the guide cable 4 is fixed to the top of the building, and the lower end is fixed to the ground at the base of the building. The walking device includes two walking wheels 5 that clamp the guide cable 4. The two walking wheels 5 can be connected by an elastic element 6 such as a spring to ensure that the two walking wheels 5 have a certain clamping force on the guide cable 4. In this embodiment, the walking wheels 5 are set on the telescopic device 3 and supported between the guide cable 4 and the plate 1, ensuring that the plate 1 faces the concrete surface 7, thereby roughening the concrete surface 7 from bottom to top.
[0034] like Figure 5 , 6 As shown, in this embodiment, two plates 1 are arranged along the track direction. The telescopic devices 3 of the two plates 1 are connected by a spacing adjustment device 8 to form a movable chiseling module. The spacing adjustment device 8 controls the distance between the two plates 1. The spacing adjustment device 8 can also be a spacing adjustment device 8 controlled by a pneumatic cylinder, hydraulic cylinder or electric cylinder.
[0035] The movable chiseling module can move relative to the concrete surface 7 along the guide cable 4 through the telescopic cooperation of the spacing adjustment device 8 and the telescopic device 3. For example, when the movable chiseling module needs to move upward, the lower plate 1 can extend relative to the spacing adjustment device 8 toward the concrete surface 7, so that the chiseling teeth 2 of the lower plate 1 chisel out pits and burrs on the concrete surface 7 while supporting it on the concrete surface 7. Then, the upper plate 1 retracts relative to the spacing adjustment device 8 toward the concrete surface 7, so that the chiseling teeth 2 leave the concrete surface 7. Then, the spacing adjustment device 8 extends, so that the upper plate 1 moves upward. When it moves to a certain position... After a certain distance is reached, the spacing adjustment device 8 stops extending. Then, the upper plate 1 extends towards the concrete surface 7 relative to the spacing adjustment device 8, so that the chisel teeth 2 of the upper plate 1 chisel out pits and burrs on the concrete surface 7 while being supported on the concrete surface 7. Then, the lower plate 1 retracts towards the concrete surface 7 relative to the spacing adjustment device 8, so that the chisel teeth 2 leave the concrete surface 7. Then, the spacing adjustment device 8 retracts, so that the lower plate 1 moves upward. Then, the lower plate 1 extends towards the concrete surface 7 relative to the spacing adjustment device 8 again. This process is repeated to realize the movement of the moving chisel module relative to the concrete surface 7 along the guide cable 4.
[0036] The two ends of the guide cable 4 can be fixed relative to the concrete surface 7 by means of a height adjustment device 9. The height adjustment device 9 can also be a device controlled by a pneumatic cylinder, hydraulic cylinder, or electric cylinder.
[0037] like Figure 7 As shown, each tooth of the chisel teeth 2 is set inside the guide cylinder 10. Each tooth is a rod with a pointed tip at the front end. The rod is controlled to extend and retract by a telescopic mechanism such as a solenoid valve 11. When the plate 1 causes the front end of the guide cylinder 10 to press against the concrete surface 7, the solenoid valve 11 controls the rod to extend quickly, thereby chiseling a pit into the concrete surface 7.
[0038] Furthermore, it may also include a suction cup device 15 fixed relative to the plate body 1 for adsorbing the concrete wall surface. The suction cup of the suction cup device 15 is controlled by a telescopic mechanism to move relative to the concrete wall surface. The suction cup is located in front of the plate body 1. The suction cup can assist in adsorbing the wall surface when roughening, thereby achieving the effect of counteracting the reaction force and strengthening the fixation.
[0039] Furthermore, the traveling wheel 5 can be controlled by the traction rope 12 to move along the track, and the traction rope 12 is controlled by the winch 13 to extend and retract, thereby causing the plate 1 to move along the guide cable 4.
[0040] Of course, the traction rope 12 can be omitted, and one of the walking wheels 5 can be controlled to rotate by a power device, such as a motor, so that both walking wheels 5 can automatically climb along the traction rope 12.
[0041] Example 2:
[0042] like Figure 8 As shown, unlike the above embodiment, the spacing adjustment device 8 of the two side-by-side movable chiseling modules is fixedly connected by the bracket 14, that is, there are four plates 1. In this way, the four plates 1 move like a four-legged crawling animal by the extension and retraction cooperation of the spacing adjustment device 8 and the telescopic device 3, making the movement of the device more stable.
[0043] Furthermore, each movable chiseling module moves along a different track, that is, along two parallel guide cables 4.
[0044] Although this document uses a number of technical terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of the invention; interpreting them as any additional limitation would contradict the spirit of the invention. The order of actions, steps, etc., in the apparatus and methods shown in the specification and drawings can be implemented in any order unless otherwise expressly specified, and provided that the output of a preceding process is not used in a subsequent process. Similar sequential terms used for descriptive convenience (e.g., "firstly," "next," "secondly," "again," "then," etc.) do not imply that the actions must be performed in such an order.
[0045] Those skilled in the art will understand that all directional references (e.g., above, below, up, down, down, top, bottom, left, right, vertical, horizontal, etc.) are used descriptively in the drawings to aid the reader's understanding and do not imply (e.g., a limitation on the scope of the invention as defined by the appended claims) a limitation on the location, orientation, or use of the invention, but are merely for the purpose of facilitating the description of this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a particular orientation or be constructed and operated in a particular orientation. The directional terms "inside" and "outside" refer to inside or outside relative to the outline of the respective component itself.
[0046] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0047] Additionally, some vague terms (e.g., substantially, certain, generally, etc.) may refer to slight inaccuracies or minor deviations in conditions, quantities, values, or dimensions, some of which are within manufacturing tolerances or limits. It should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components; unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.
[0048] The specific embodiments described herein are merely illustrative examples illustrating the spirit of the invention. Those skilled in the art can make various modifications or additions to the described embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
