Description

Technical Field

[0001] The utility model relates to the field of production of precast concrete components, and particularly relates to a surface roughening device for precast components. Background Art

[0002] At present, the production of precast concrete components usually relies on dedicated production lines, which are designed for components with large production volumes and easy mechanized production. Correspondingly, the surface roughening treatment of components is usually completed by dedicated roughening machines to achieve high-efficiency and high-quality surface treatment. However, for non-standard or small-batch components, the roughening work often relies on manual operation, which is not only inefficient but also difficult to ensure the consistency of treatment. Although there are some precast component production lines on the market that can process multiple components, the roughening equipment they are equipped with often has limited functions and can only adapt to the roughening requirements of a few types of components. For example, the Chinese patent application document with the publication number CN112077991A discloses a multi-functional roughening device. The device includes a mobile bearing gantry, a depth adjustment mechanism, a bearing plate, and several groups of roughening components, which can adjust the roughening width and be horizontally distributed to adapt to different components. Nevertheless, the device still has limitations: it can only roughen in a single direction along the surface of the precast component and cannot adapt to components with special-shaped surfaces such as arc surfaces and inclined surfaces, so its applicability is limited. In addition, when encountering obstacles such as the surface of a component that cannot be directly roughened or embedded parts, the existing equipment usually needs to lift to avoid them. This process is not only cumbersome and time-consuming but may also result in improper roughening treatment around the avoidance area, thereby affecting the roughening effect and overall performance of the component. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a precast component roughening device that is easy to operate, does not require additional lifting and avoidance operations when encountering obstacles during the roughening process, ensures the roughening effect around the obstacle area, and has high roughening efficiency.

[0004] To solve the above technical problem, the utility model adopts the following technical solutions:

[0005] A precast component roughening device includes a mounting frame, a roughening knife movably connected to the mounting frame, and a rotating mechanism for driving the mounting frame to rotate.

[0006] As a further improvement of the above technical solution: the roughening knife is hinged to the mounting frame, and a pressing component is connected between the roughening knife and the mounting frame for pressing the roughening knife against the surface of the precast component.

[0007] As a further improvement of the above technical solution: the roughening knife is hinged to the mounting frame by bolts, and anti-loosening nuts are provided on the bolts.

[0008] As a further improvement of the above technical solution: the pressing member is an elastic member.

[0009] As a further improvement of the above technical solution: the pressing member is a spring.

[0010] As a further improvement of the above technical solution: the pressing member is a limit block.

[0011] As a further improvement of the above technical solution: a plurality of roughening knives are provided and are spaced along the length direction of the mounting frame.

[0012] As a further improvement of the above technical solution: it further includes a driving mechanism for adjusting the spatial position of the mounting frame, the driving mechanism includes a frame, a longitudinal moving trolley provided on the frame, a transverse moving trolley provided on the longitudinal moving trolley, and a lifting mechanism provided on the transverse moving trolley, and the lifting mechanism is connected to the mounting frame.

[0013] As a further improvement of the above technical solution: a longitudinal moving track cooperating with the longitudinal moving trolley is provided on the frame, and a transverse moving track cooperating with the transverse moving trolley is provided on the longitudinal moving trolley.

[0014] As a further improvement of the above technical solution: a lifting guiding structure is provided between the transverse moving trolley and the lifting mechanism.

[0015] Compared with the prior art, the advantages of the present utility model are as follows: in the precast component roughening device disclosed by the present utility model, the rotating mechanism can drive the mounting frame to rotate and then drive the roughening knife to rotate, so that when the precast component passes through, the roughening knife can perform roughening operations with different paths and different orientations on its surface, thereby being able to match the roughening operations of special-shaped precast components, and the applicable range of the roughening operation is wide; when the roughening knife contacts the non-roughenable surface or obstacles such as embedded parts on the precast component when the precast component passes through, since the roughening knife is movably connected to the mounting frame, the roughening knife can perform an adaptive movement to separate from the surface of the precast component and pass along the surface of the obstacle such as the embedded part. When the roughening knife leaves the obstacle, under the action of gravity, the roughening knife will reattach to the surface of the precast component, reducing the generation of non-roughened areas and ensuring that both the areas before and after the obstacle can be roughened. The precast component roughening device of the present utility model has a low degree of manual participation, saves labor, does not require additional lifting operations when encountering obstacles during the roughening operation, simplifies the use process, is convenient to operate, and has a high roughening efficiency.

[0028] Embodiment 1

[0029] Figures 1 to 5 Fig. shows an embodiment of the surface roughening device for precast components of the present utility model. The surface roughening device for precast components in this embodiment includes a mounting frame 1, a surface roughening knife 2 movably connected to the mounting frame 1, and a rotating mechanism 5 for driving the mounting frame 1 to rotate. Specifically, the mounting frame 1 is rotatably connected to the lifting mechanism 34 through a rotating shaft, bearings, etc. The rotating mechanism 5 drives the mounting frame 1 and the surface roughening knife 2 to rotate through a servo motor, a driving wheel, a driven wheel, and a synchronous belt. Of course, in other embodiments, the mounting frame 1 and the surface roughening knife 2 can also be driven to rotate through a meshing gear set, which will not be elaborated here.

[0030] For the surface roughening device for precast components in this embodiment, the rotating mechanism 5 can drive the mounting frame 1 to rotate and then drive the surface roughening knife 2 to rotate, so that when the precast component passes through, the surface roughening knife 2 can perform surface roughening operations with different paths and orientations on its surface, thereby matching the surface roughening operations of special-shaped precast components, and the applicable range of the surface roughening operation is wide; when the surface roughening knife 2 moves and contacts the surface of the precast component that cannot be roughened or obstacles such as embedded parts, since the surface roughening knife 2 is movably connected to the mounting frame 1, the surface roughening knife 2 can perform adaptive movement to separate from the surface of the precast component and pass along the surface of the embedded part and other obstacles. When the surface roughening knife 2 is separated from the obstacle, under the action of gravity, the surface roughening knife 2 will reattach to the surface of the precast component, reducing the generation of unroughened areas and ensuring that the areas before and after the obstacle can be subjected to surface roughening operations.

[0031] Specifically refer to Figure 4 and Figure 5 , further, in this embodiment, the surface roughening knife 2 is hinged to the mounting frame 1, and a pressing component 4 for pressing the surface roughening knife 2 against the surface of the precast component is connected between the surface roughening knife 2 and the mounting frame 1. Specifically, the surface roughening knife 2 is hinged to the mounting frame 1 through bolts, and anti-loosening nuts are provided on the bolts. The bolt and nut structure is simple and effective, and the surface roughening knife 2 is convenient to disassemble and assemble. Of course, in other embodiments, other hinged methods such as hinge connection and pin shaft connection can also be used, which will not be elaborated here. When the concrete precast component moves relative to the surface roughening knife 4, the pressing component 4 presses the surface roughening knife 2 against the surface of the precast component, which is beneficial to ensuring the consistency of the roughening depth of the surface roughening knife 2 and ensuring the quality of the surface roughening operation; after the surface roughening knife 2 passes through the obstacle, it will immediately reattach to the surface of the precast component under the action of gravity and pressure, further reducing the generation of unroughened areas.

[0032] See specifically Figure 5 Figure 5 , further, in this embodiment, the pressing member 4 is an elastic member, and the pressing member 4 is preferably a spring. When the hair-removing knife 2 contacts the concrete surface of the precast member and performs the hair-removing operation, it can rotate around the hinge point with the mounting frame 1. At this time, the pressing member 4 composed of the spring will elongate and apply an elastic force to the hair-removing knife 2, prompting it to closely fit the concrete surface, preventing the hair-removing knife 2 from separating from the concrete surface, which is beneficial to maintaining a consistent hair-removing depth and ensuring the operation quality. When encountering an obstacle, the hair-removing knife 2 can rotate around the hinge point and smoothly cross the surface of the obstacle. Once separated from the obstacle, the hair-removing knife 2 quickly resumes contact with the concrete surface under its own gravity and the resilience of the spring and continues the hair-removing operation, which not only improves the continuity of the operation but also enhances the adaptability of the equipment and can effectively handle complex surfaces with obstacles. Of course, in other embodiments, the pressing member 4 can also be other elastic components such as reed pieces or elastic rubber blocks.

[0033] Further, in this embodiment, the width of the hair-removing end of the hair-removing knife 2 gradually becomes narrower from top to bottom. This structure can reduce the contact area between the hair-removing end of the hair-removing knife 2 and the concrete on the surface of the precast member during hair-removing, making the hair-removing smoother.

[0034] See specifically Figures 1 to 3 Figures 1 to 3 , further, in this embodiment, a plurality of hair-removing knives 2 are provided and are spaced along the length direction of the mounting frame 1. By increasing the number of hair-removing knives 2, the efficiency of the hair-removing operation can be further improved, saving the operation time.

[0035] Further, in this embodiment, the precast member hair-removing device further includes a driving mechanism 3 for adjusting the spatial position of the mounting frame 1. The driving mechanism 3 includes a frame 31, a longitudinal moving trolley 32 provided on the frame 31, a transverse moving trolley 33 provided on the longitudinal moving trolley 32, and a lifting mechanism 34 provided on the transverse moving trolley 33 (which can be driven by a rack and pinion, an oil cylinder, an electric push rod or a screw nut mechanism, etc.), and the lifting mechanism 34 is rotatably connected to the mounting frame 1. The lifting mechanism 34 can drive the mounting frame 1 and the hair-removing knife 2 connected to the mounting frame 1 to lift as a whole, so as to contact or separate from the concrete on the surface of the precast member; the transverse moving trolley 33 can drive the lifting mechanism 34, the hair-removing knife 2, etc. to move horizontally as a whole; correspondingly, the longitudinal moving trolley 32 can drive the transverse moving trolley 33, the lifting mechanism 34, the hair-removing knife 2, etc. to move longitudinally as a whole, so that the hair-removing knife 2 can reach any position on the surface of the precast member, and then cooperate with the rotating mechanism 5, so that the hair-removing knife 2 can realize various hair-removing methods in different directions, different heights and different paths, so as to be able to match various components, especially special-shaped components, with strong adaptability and reliable operation.

[0036] See specifically Figure 4, Further, in this embodiment, a longitudinal movement track 35 cooperating with the longitudinal movement trolley 32 is provided on the frame 31, and a transverse movement track 36 cooperating with the transverse movement trolley 33 is provided on the longitudinal movement trolley 32. Specifically, a rack 321 is provided on the longitudinal movement trolley 32, a transmission gear 331 meshing with the rack 321 and a rotation driving mechanism 332 (such as a rotary oil cylinder, a servo motor, etc.) for driving the transmission gear 331 to rotate are provided on the transverse movement trolley 33. The rotation driving mechanism 332 drives the transmission gear 331 to rotate, thereby driving the transverse movement trolley 33 to move along the transverse movement track 36. The longitudinal movement track 35 can provide a guiding function for the longitudinal movement trolley 32, and the transverse movement track 36 can provide a guiding function for the transverse movement trolley 33, which is beneficial to ensuring the stability and safety of the longitudinal movement trolley 32 and the transverse movement trolley 33 during the movement process and avoiding deviation.

[0037] Specifically refer to Figure 4 , Further, in this embodiment, a lifting guiding structure 37 is provided between the transverse movement trolley 33 and the lifting mechanism 34 to ensure the stability of the lifting mechanism 34 during the lifting process and avoid deviation. Preferably, the lifting guiding structure 37 can be a plurality of guiding wheels symmetrically distributed on both sides of the transverse movement trolley 36, with a simple and effective structure.

[0038] The using method of the precast component roughening device in this embodiment is as follows:

[0039] The longitudinal movement trolley 32 and the transverse movement trolley 33 first drive the plurality of roughening knives 2 on the mounting frame 1 to move to directly above the precast component to be roughened. Subsequently, the lifting mechanism 34 lowers the mounting frame 1 according to the height of the precast component, so that the roughening knives 2 are closely attached to the concrete surface of the precast component. After setting the roughening path of the roughening knives 2 according to the shape of the precast component, the longitudinal movement trolley 32, the transverse movement trolley 33 and the rotation mechanism 5 drive the mounting frame 1 to move, so that each roughening knife 2 travels along the preset roughening path to perform roughening operations on the precast component to be roughened. After roughening is completed, the lifting mechanism 34 raises the mounting frame 1 to separate the roughening knives 2 from the surface of the precast component, and then the longitudinal movement trolley 32 and the transverse movement trolley 33 drive the roughening knives 2 on the mounting frame 1 to move to directly above the next precast component to be roughened. Repeat the above steps until all precast components are completed with roughening operations.

[0040] Embodiment 2

[0041] Figures 6 to 8 Another embodiment of the precast component roughening device of the present invention is shown. This embodiment is substantially the same as Embodiment 1, except that:

[0042] In this embodiment, the pressing component 4 is a limiting block. When the scarifying tool 2 encounters an obstacle, the scarifying tool 2 can rotate around the hinge point and smoothly cross the surface of the obstacle. When the scarifying tool 2 rotates to a certain angle, it will touch the limiting block and stop rotating, ensuring that the scarifying tool 2 can always be in contact with the concrete surface. After crossing the obstacle, the scarifying tool 2 resets under its own gravity. Compared with the first embodiment, the structure is simpler, and it can avoid the defect that the elastic component undergoes irreversible elastic deformation during long-term use.
