Description

Technical Field

[0001] This invention relates to the field of manufacturing technology for concrete structural components such as precast reinforced concrete frames, and in particular to an integrated device for roughening and cutting anchor holes. Background Technology

[0002] Anchor hole roughening cutting refers to the process of mechanically roughening the inner wall of the reserved hole (anchor hole) in a precast concrete component. Its core purpose is to thoroughly remove the laitance and oil residue left by the hole-making tool in the hole and transform the smooth surface into an uneven rough surface, thereby significantly increasing the bonding area and mechanical interlocking force between the new and old concrete. During prestressed tensioning grouting or secondary pouring of joints, it can effectively prevent the anchor end from slipping or cracking due to poor interface bonding, ensuring the integrity and safety of the structure under stress.

[0003] Currently, the following problems still exist when roughening and cutting anchor holes: In existing technologies, roughening anchor holes and cutting steel strands are usually completed in steps by independent equipment, requiring multiple moves and replacements of equipment, resulting in low construction efficiency and difficulty in ensuring the positioning consistency of cutting and roughening. Moreover, after cutting, the ends of the steel strands are prone to loosening and warping, which can easily cause the steel strands to shake and interfere with subsequent roughening operations. At the same time, conventional roughening devices can only impact the bottom surface of the anchor hole at a fixed angle, resulting in insufficient roughening of the sidewalls of the anchor hole and affecting the bonding strength between the old and new concrete.

[0010] Preferably, a limiting plate is fixedly installed inside the limiting cylinder, and a limiting hole corresponding to the elastic positioning rod is opened through the limiting plate. A first spring is fixedly installed between the elastic positioning rod and the limiting cylinder.

[0011] Preferably, a hinged frame corresponding to each floating cylinder is fixedly installed on the bearing ring plate, and a second electric slide rail is fixedly installed on each of the other support rods, with the moving end of the second electric slide rail being fixedly connected to the bearing ring plate.

[0012] Preferably, the floating cylinder includes a floating outer cylinder hinged to a hinge frame, a floating inner cylinder slidably installed inside the floating outer cylinder, a protruding plate fixedly installed on the outer ring wall of the floating inner cylinder, a plurality of second springs fixedly installed between the protruding plate and the floating outer cylinder, a plurality of balls rotatably installed on the outer ring wall of the floating inner cylinder in an array, and an air hammer fixedly installed inside the floating inner cylinder.

[0013] Preferably, the angle adjustment assembly includes a protrusion fixedly mounted on the hinge frame, and a third electric telescopic rod is hinged between the protrusion and the corresponding floating outer cylinder.

[0014] Preferably, the extrusion assembly includes a second pneumatic telescopic rod fixedly mounted on the hinge frame and near the limiting cylinder, and an arc-shaped pressure plate is fixedly mounted on the telescopic end of the second pneumatic telescopic rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting several elastic positioning rods to adaptively compress and position the steel strands, it can adapt to steel strands of different diameters and quantities, ensuring that the ends of the steel strands do not loosen after cutting, providing fixation for subsequent roughening. The floating cylinder, in conjunction with the angle adjustment component, can flexibly adjust the angle of the air hammer to achieve all-round roughening of the bottom and side walls of the anchor hole, ensuring uniform roughening within the anchor hole and improving the bonding strength between the old and new concrete. Moreover, the compression component acts directly on the limiting cylinder, using the fixed ends of the steel strands as a support reference, providing stable reaction force for the floating cylinder and air hammer, ensuring consistent roughening depth and smooth operation. Thus, the equipment can simultaneously perform steel strand cutting, wire harness fixing, and anchor hole roughening functions, completing multiple processes without changing equipment, significantly improving construction efficiency and continuity.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 An integrated anchor hole chiseling and cutting device includes a mobile platform 1 and a robotic arm 2 fixedly installed thereon. A cylindrical rotating frame 3 is rotatably installed on the mobile end of the robotic arm 2. A support ring 4 is fixedly installed at the front end of the cylindrical rotating frame 3. A cutting component 42 for cutting steel strands is provided on the support ring 4.

[0030] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6The limiting and fixing mechanism 5 is set on the cylindrical rotating frame 3. The limiting and fixing mechanism 5 includes a telescopic component 51 fixedly installed in the cylindrical rotating frame 3. A limiting cylinder 52 is fixedly installed on the telescopic component 51. Several elastic positioning rods 53 are slidably installed in the limiting cylinder 52 in an array. The telescopic component 51 drives the limiting cylinder 52 to approach the steel strand. The steel strand squeezes the corresponding elastic positioning rods 53 to fix the steel strand.

[0031] Please see Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8 The steering and chiseling mechanism 6 is set inside the cylindrical rotating frame 3. The steering and chiseling mechanism 6 includes a bearing ring plate 61 that is slidably installed inside the cylindrical rotating frame 3. Several floating cylinders 62 are hinged on the bearing ring plate 61 and an angle adjustment component 64 for adjusting the angle of the floating cylinders 62. A pneumatic hammer 63 is fixedly installed inside the floating cylinders 62. An extrusion component 65 is also provided on the bearing ring plate 61.

[0032] The floating cylinder 62 works in conjunction with the angle adjustment component 64. The air hammer 63 can roughen the plane and side of the anchor hole. The limiting cylinder 52 fixes the cut steel strand. The extrusion component 65 extrudes the limiting cylinder 52 to provide support for several floating cylinders 62.

[0033] In actual operation, the mobile platform 1 can carry the entire equipment and enable it to move within the work area. The robotic arm 2 can perform multi-degree-of-freedom movements to deliver the work tools to the anchor position. The air hammer 63 is fixedly installed inside the floating cylinder 62 and generates impact force through the air source for chiseling operations. The cylindrical rotating frame 3 can rotate to adjust the orientation of its internal working mechanism.

[0034] The elastic positioning rod 53 can retract inward when subjected to external pressure and return to its original position after the pressure is released. When the telescopic component 51 drives the limiting cylinder 52 to approach the steel strand, the steel strand will squeeze the corresponding part of the elastic positioning rod 53, thereby applying radial pressure to the steel strand by the elastic positioning rod 53, thus fixing the steel strand.

[0035] Thus, when the cutting component 42 is cutting, the limiting and fixing mechanism 5 can fix the steel strand. After the cutting is completed, the cut steel strand can be taken out through the limiting and fixing mechanism 5, and the cylindrical rotating frame 3 can be inserted into the anchor hole again. At this time, the limiting and fixing mechanism 5 fixes the cut steel strand.

[0036] Subsequently, the bearing ring plate 61 slides into the anchor hole inside the cylindrical rotating frame 3, which can then activate the air hammer 63 to provide power through the air source to roughen the anchor hole, while the angle adjustment component 64 adjusts the swing angle of the floating cylinder 62.

[0037] Therefore, by adjusting the angle of the floating cylinder 62 through the angle adjustment component 64, the impact direction of the air hammer 63 can be adjusted from perpendicular to the bottom surface of the anchor hole to inclined to the side of the anchor hole, thereby achieving roughening of the inner wall of the anchor hole. The limiting cylinder 52 is fixed after the steel strand is cut to prevent it from shaking during the roughening process. The extrusion component 65 provides support for several floating cylinders 62 during the roughening operation by extruding the limiting cylinder 52, thereby enhancing the stability and efficiency of the roughening.

[0038] By integrating steel strand cutting and anchor hole roughening functions into the same equipment, the problems of multiple equipment movements, replacements, and inconsistent positioning caused by traditional step-by-step operations are avoided, thus improving construction efficiency. The cut steel strand can be fixed in time by the limiting and fixing mechanism 5 to prevent it from loosening or shaking, providing a good operating environment for subsequent roughening operations. The floating cylinder 62 and the angle adjustment component 64 of the turning roughening mechanism 6 cooperate to allow the air hammer 63 to adjust the roughening angle, thereby roughening the anchor hole plane and sidewalls, solving the problem of insufficient sidewall roughening in traditional devices, and thus ensuring the bonding strength and structural integrity of new and old concrete.

[0039] Please see Figure 2 , Figure 3 and Figure 4 A motor 31 is also fixedly installed on the moving end of the robotic arm 2. The output end of the motor 31 is connected to the cylindrical rotating frame 3 through a gear transmission assembly. The cylindrical rotating frame 3 includes several support rods 32 fixedly installed in a circumferential array between the cylindrical rotating frame 3 and the support ring 4.

[0040] During operation, the motor 31 drives the cylindrical rotating frame 3 to rotate, ensuring the stability of the cutting component 42 and the steering chiseling mechanism 6 inside the anchor hole. Several support rods 32 enhance the overall rigidity of the cylindrical rotating frame 3, making the support ring 4 less prone to deformation or shaking when bearing the reaction force generated by the cutting component 42 or the steering chiseling mechanism 6 during high-intensity chiseling impact or fine cutting, thus improving the structural reliability of the equipment under complex working conditions.

[0041] Please see Figure 2 , Figure 3 and Figure 4 The support ring 4 is also provided with an expansion component 41 for positioning the cylindrical rotating frame 3 with the anchor hole as a reference. The expansion component 41 includes a positioning groove 411 that is opened through the outer ring wall of the support ring 4 in a circumferential array. A support arm 412 is hinged in the positioning groove 411. A roller 413 is rotatably installed on the side of the support arm 412 away from the positioning groove 411. A first pneumatic telescopic rod 414 that is hinged to the corresponding support arm 412 is also hinged in the positioning groove 411.

[0042] In actual operation, the first pneumatic telescopic rod 414 drives the support arm 412 to expand outward, so that the roller 413 at the end of the support arm 412 can closely abut against the inner wall of the anchor hole, ensuring that the cylindrical rotating frame 3 is in close contact with the inner wall of the anchor hole to achieve radial positioning. At the same time, it reduces the frictional resistance of the cylindrical rotating frame 3 when rotating in the anchor hole, and through multiple support points, the cylindrical rotating frame 3 is forcibly fixed in the center position of the anchor hole, thereby eliminating the displacement deviation generated by the robotic arm 2 during operation, ensuring that the subsequent cutting component 42 and the steering chiseling mechanism 6 can always operate in the preset center, thereby improving the uniformity of chiseling and the accuracy of cutting, and solving the problem of decreased operation accuracy caused by differences in the internal space of the anchor hole and inaccurate positioning of equipment movement.

[0043] Please see Figure 2 and Figure 4 The cutting assembly 42 includes a first electric slide rail 421 fixedly mounted on one of the support rods 32. A first electric telescopic rod 422 is fixedly mounted on the moving end of the first electric slide rail 421, and a cutting blade 423 is fixedly mounted on the telescopic end of the first electric telescopic rod 422.

[0044] In actual operation, the first electric slide rail 421 allows the cutting blade 423 to be adjusted inside the anchor cavity, achieving coarse positioning of steel strands at different depths. Moreover, the first electric telescopic rod 422 enables the cutting blade 423 to perform precise radial extension and retraction, thereby achieving precise positioning of the steel strand and stable cutting feed. This allows the cutting blade 423 to perform multi-degree-of-freedom and high-precision cutting within the anchor cavity, adapting to situations where the position of the steel strand is not fixed. This ensures that the cutting blade 423 can accurately contact and cut the steel strand, avoiding damage to the anchor cavity structure due to cutting position deviation, and guaranteeing construction quality and equipment operation stability.

[0045] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6 The telescopic assembly 51 includes a second electric telescopic rod 511 fixedly installed at the center inside the cylindrical rotating frame 3. The telescopic end of the second electric telescopic rod 511 is fixedly connected to the limiting cylinder 52. Several auxiliary telescopic rods 512 are fixedly installed between the limiting cylinder 52 and the cylindrical rotating frame 3.

[0046] In actual operation, the second electric telescopic rod 511 ensures that the limiting cylinder 52 can move smoothly towards the steel strand. At the same time, the auxiliary telescopic rod 512 provides multi-point support and guidance during the extension and retraction of the limiting cylinder 52, shares the radial load, and limits the radial swing of the limiting cylinder 52, thereby enhancing the structural stability of the limiting mechanism and ensuring that the limiting cylinder 52 can be more accurately and firmly fitted around the steel strand. This provides a reliable benchmark for subsequent steel strand fixing and roughening operations, and improves the operating accuracy and stability of the equipment.

[0047] Please see Figure 6 A limiting plate 531 is fixedly installed inside the limiting cylinder 52. The limiting plate 531 has a limiting hole 532 that corresponds to the elastic positioning rod 53. A first spring 533 is fixedly installed between the elastic positioning rod 53 and the limiting cylinder 52.

[0048] In actual operation, the limiting plate 531 constrains the radial displacement of each elastic positioning rod 53 through the limiting hole 532, preventing the elastic positioning rod 53 from deflecting or misaligning when extruding the steel strand. The first spring 533 provides the necessary preload and rebound capability for the elastic positioning rod 53, enabling the elastic positioning rod 53 to adaptively adjust according to the actual shape of the steel strand, generating uniform extrusion force when in contact with the steel strand, thereby effectively binding and fixing the loose steel strand ends. In conjunction with the second electric telescopic rod 511 and the auxiliary telescopic rod 512, it can more stably position and clamp the cut steel strand, improving the working efficiency and extrusion quality of the anchor hole chiseling and cutting integrated equipment.

[0049] Please see Figure 3 , Figure 5 , Figure 7 and Figure 8 A hinged frame 612 corresponding to the floating cylinder 62 is fixedly installed on the bearing ring plate 61. A second electric slide rail 611 is fixedly installed on each of the other support rods 32. The moving end of the second electric slide rail 611 is fixedly connected to the bearing ring plate 61.

[0050] In actual operation, the second electric slide rail 611 on the other support rods 32 ensures that the bearing ring plate 61 moves accurately and smoothly along the support rods 32, and also ensures the stability and movement accuracy of the bearing ring plate 61 when roughening at multiple points. The adjustable angle between the hinge frame 612 and the floating cylinder 62 ensures that the air hammer 63 can perform comprehensive and uniform roughening operations on the plane and sides of the anchor hole, avoid roughening dead corners, improve the uniformity and overall efficiency of the roughening operation, and thus improve the quality and reliability of the roughening operation.

[0051] Please see Figure 7 and Figure 9 The floating cylinder 62 includes a floating outer cylinder 621 hinged to the hinge frame 612, a floating inner cylinder 622 slidably installed inside the floating outer cylinder 621, a protruding plate fixedly installed on the outer ring wall of the floating inner cylinder 622, a plurality of second springs 623 fixedly installed between the protruding plate and the floating outer cylinder 621, a plurality of balls 624 rotatably installed on the outer ring wall of the floating inner cylinder 622 in an array, and an air hammer 63 fixedly installed inside the floating inner cylinder 622.

[0052] In actual operation, the air hammer 63 is installed inside the floating inner cylinder 622, which slides inside the floating outer cylinder 621. This allows the air hammer 63 to generate a certain axial displacement when it contacts the wall of the anchor cavity, effectively absorbing the impact reaction force, thereby protecting the equipment structure and preventing damage to the air hammer 63 itself or excessive impact on the wall of the anchor cavity.

[0053] Meanwhile, several second springs 623 provide elastic support for the floating inner cylinder 622, ensuring that the air hammer 63 can always maintain a tight fit with the wall of the anchor hole during the impact process, avoiding the fluctuation of impact force caused by rigid contact, thereby ensuring the uniformity of the roughening.

[0054] In addition, the several balls 624 on the outer ring wall of the floating inner cylinder 622 enable the floating inner cylinder 622 to use rolling friction instead of sliding friction when moving on the anchor hole wall, reducing the moving resistance and allowing the air hammer 63 to move more smoothly on the anchor hole surface during the roughening process, ensuring the continuity of the roughening trajectory.

[0055] By combining spring buffering, rolling guidance, and articulated floating, the technical problems of unstable impact and uneven contact of the pneumatic hammer 63 in complex anchor hole environments are solved, achieving efficient and uniform roughening operations and significantly improving the quality and efficiency of anchor hole roughening.

[0056] Please see Figure 7 and Figure 9 The angle adjustment assembly 64 includes a protrusion 641 fixedly installed on the hinge frame 612, and the protrusion 641 and the corresponding floating outer cylinder 621 are hinged together by a third electric telescopic rod 642.

[0057] In specific operation, when the third electric telescopic rod 642 extends or retracts, it drives the floating outer cylinder 621 to rotate around the hinge frame 612, thereby changing the tilt angle of the floating cylinder 62. This allows the air hammer 63 to adjust the impact angle in real time according to the actual tilt of the side wall or bottom of the anchor hole, ensuring that the impact force of the air hammer 63 can act vertically or at the optimal angle on the surface of the anchor hole. This improves the targeting and coverage of the roughening operation, solves the problem of insufficient roughening caused by a fixed angle, ensures that a good mechanical interlocking surface can be formed between the new and old concrete, and improves the reliability of the anchoring and the safety of the structure.

[0058] Please see Figure 3 , Figure 7 and Figure 8 The extrusion assembly 65 includes a second pneumatic telescopic rod 651 fixedly mounted on the hinge frame 612 and close to the side of the limiting cylinder 52. An arc-shaped pressure plate 652 is fixedly mounted on the telescopic end of the second pneumatic telescopic rod 651.

[0059] In actual operation, during the chiseling process, the second pneumatic telescopic rod 651 can drive the arc-shaped pressure plate 652 to tightly squeeze the limiting cylinder 52. After the steel strand is fixed, the limiting cylinder 52 is in a relatively stable state. As a support reference, it can effectively absorb and disperse the reaction force and vibration generated by the air hammer 63 during chiseling. The arc-shaped pressure plate 652 ensures a large area of ​​contact with the outer wall of the limiting cylinder 52, thereby providing stable support.

[0060] This support mechanism limits the swaying and positional displacement of the floating cylinder 62 during the roughening process, improves the stability and accuracy of the steering roughening mechanism 6 when roughening the anchor hole plane and side, and ensures the reliability of the bonding between new and old concrete.

[0061] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
