Abstract
Description
Technical Field
[0001] This invention relates to the field of building equipment technology, specifically to a prestressed steel bar anchorage reinforcement device. Background Technology
[0002] When cracks appear in the walls of the six-cell concrete silo, requiring external prestressed reinforcement, drilling holes at the intersection of the two silos is a crucial step. This is because the intersection contains a relatively thick section of concrete. Therefore, before drilling through this concrete section, the locations of the holes at the intersection must first be determined. These locations are usually marked on the existing structural drawings. It is essential to ensure that the drilling locations correspond to the layout of the prestressed reinforcement and the location of the cracks in the silo walls. Appropriate drilling equipment, typically electric or hydraulic drilling rigs, is then selected for drilling into the concrete silo walls. Drilling begins at the intersection of the two reservoirs at the required location and depth, ensuring the boreholes are vertical to facilitate subsequent prestressing tendon installation. During drilling, debris and mud are promptly removed to ensure the boreholes are clean. Prestressing tendon installation: Once drilling is complete, the prestressing tendons are installed into the boreholes, ensuring the tendons are correctly positioned and that the prestressing tendon layout at the intersection of the two reservoirs meets design requirements. Grouting: After tensioning the prestressing tendons, grout is injected into the drilled boreholes to fix the tendons in place and improve the load-bearing capacity of the reservoir walls.
[0003] After fixing the anchor at the drilled position, the steel cable needs to be threaded through the anchor and then tensioned. During the process of threading the steel cable through the anchor, because the steel cable is relatively thick and the locking hole of the anchor is relatively dry, the friction generated when the steel cable passes through the locking hole of the anchor is relatively large, making the threading process relatively difficult.
[0004] Based on this, the present invention designs a prestressed steel bar anchorage reinforcement device to solve the above problems. Summary of the Invention

[0010] The feeding structure includes: a rotating handle, a linkage rod, a control component, a driving component, and a hinge rod.

[0011] The control component further includes: a sliding handle and a limiting rail. The side of the control component is fixedly connected to the end of the sliding handle, the sliding handle is slidably connected to the groove of the limiting rail, and the end of the limiting rail is fixedly connected to the inner wall of the lubricating oil feed hopper.
[0012] The driving component also includes: a guide wheel and a suction head. The lower part of the driving component is fixedly connected to the middle part of the guide wheel. The column at the lower part of the guide wheel is slidably connected to the straight groove opened in the lubricating oil inlet. The end of the driving component is fixedly connected to the suction head.
[0013] The detection structure includes: a connecting cylinder, a toggle head, a friction element, and a friction ring. The end of the connecting cylinder is fixedly connected to the shaft of the rotating handle, the inner wall of the connecting cylinder is slidably connected to the toggle head, the end of the toggle head is fixedly connected to one end of the friction element, and the other end of the friction element is fixedly connected to the end of the friction ring.

[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. The present invention, through the design of the lubrication structure, enables the lubricant on the outer wall of the steel cable to be separated, avoiding excessive lubricant from being applied to the outer wall of the steel cable, and also lubricates the inner wall of the steel cable perforation, making the subsequent passage of steel cables smoother.
[0018] 2. The present invention, through the setting of the feeding structure, enables the outer wall of the steel cable to be coated with lubricant, avoiding excessive friction when the steel cable passes through the steel cable piercing hole due to the dry outer wall, which would make it difficult for the steel cable to pass through the steel cable piercing hole. Moreover, the control component can also quantitatively dispense the lubricant to avoid excessive dispensing and waste.
[0019] 3. In this invention, the friction generated when the steel cable passes through the cable perforation hole drives the detection structure to operate. The detection structure controls the feeding structure to release lubricant to lubricate the steel cable. When the friction of the steel cable is low, it means that the steel cable does not need lubrication. At this time, the detection structure will not operate and will not control the feeding structure to lubricate the steel cable. Thus, the detection structure controls whether the feeding structure needs to lubricate the steel cable based on the magnitude of the friction of the outer wall of the steel cable.

[0030] Please see Figures 1-8 The present invention provides a technical solution: a prestressed steel bar anchorage reinforcement device, including an anchor 2, a plurality of steel cable through holes 21 are opened around the outer periphery of the anchor 2, a feeding structure 4 is provided in the middle through hole of the anchor 2, the feeding structure 4 is used to release lubricating oil to the steel cable passing through the steel cable through holes 21, a lubricating oil inlet 22 is provided at the front of the feeding structure 4, a plurality of lubrication structures 3 are provided at the front of the feeding structure 4, the lubrication structures 3 are used to apply the lubricating oil on the steel cable to the inner wall of the steel cable through holes 21, and a detection structure 5 is provided at the rear of the feeding structure 4, the detection structure 5 is used to control the feeding structure 4;
[0031] After the through hole of the six-linkage reservoir 1 is drilled, the anchor 2 is fixed in the through hole of the six-linkage reservoir 1. When the steel cable passes through the steel cable through hole 21 from the rear of the anchor 2, if the outer wall of the steel cable is relatively dry and it is difficult to pass through the steel cable through hole 21, the steel cable will drive the detection structure 5 to move. At this time, the detection structure 5 will control the feeding structure 4 to release the lubricating oil. After the lubricating oil is spread by the movement of the steel cable, the steel cable can pass through the steel cable through hole 21 more smoothly. When the steel cable passes through the steel cable through hole 21, the friction of the steel cable drives the lubrication structure 3 to move. The lubrication structure 3 will spread the lubricant evenly on the outer wall of the steel cable and spread the lubricant to the inner wall of the steel cable through hole 21, so that the subsequent steel cable passes through more smoothly.
[0032] As a further embodiment of the present invention, the lubrication structure 3 includes: a positioning handle 31, a friction wheel 311, a short rod 32, a long rod 33, and an applicator 34. One end of the positioning handle 31 is fixedly connected to the inner wall of the through hole in the middle of the anchor 2, and the other end of the positioning handle 31 is rotatably connected to the shaft of the friction wheel 311. The end of the shaft of the friction wheel 311 is fixedly connected to one end of the short rod 32, and the other end of the short rod 32 is rotatably connected to one end of the long rod 33. The other end of the long rod 33 is rotatably connected to the side wall of the applicator 34.
[0033] The coating component 34 further includes: a coating ring 341, a guide post 342, and a limiting block 343. One end of the coating component 34 is fixedly connected to the end of the coating ring 341, and the other end of the coating component 34 is slidably connected to the column of the guide post 342. One end of the guide post 342 is fixedly connected to the dispensing structure 4, and the other end of the guide post 342 is fixedly connected to the limiting block 343.
[0034] When the steel cable passes through the steel cable through hole 21, because the wheel part of the friction wheel 311 protrudes into the opening groove on the side wall of the steel cable through hole 21, the friction of the steel cable will drive the friction wheel 311 to rotate when the steel cable passes through the friction wheel 311. The shaft of the friction wheel 311 is fixedly connected to the short rod 32, so the friction wheel 311 will drive the short rod 32 to rotate synchronously. The rotation of the short rod 32 will drive the long rod 33 to move back and forth. The end of the long rod 33 is rotatably connected to the coating part 34. 33 will drive the coating component 34 to move back and forth. The coating component 34 slides under the restriction of the limiting track 432. The coating component 34 is also fixedly connected to the coating ring 341. Therefore, the coating component 34 will drive the coating ring 341 to move back and forth on the inner wall of the steel cable through hole 21. At this time, the coating ring 341 will scrape the lubricant on the outer wall of the steel wire, so that the lubricant is evenly coated. In addition, the lubricant will also be coated on the inner wall of the steel cable through hole 21, so that the steel cable passing through later will be smoother.
[0035] The lubrication structure 3 allows the lubricant on the outer wall of the cable to be separated, preventing excessive lubricant from being applied to the outer wall of the cable. It also lubricates the inner wall of the cable perforation 21, making the subsequent passage of the cable smoother.
[0036] As a further embodiment of the present invention, the feeding structure 4 includes: a rotating handle 41, a linkage rod 42, a control component 43, a driving component 44, and a hinge rod 45. The shaft of the rotating handle 41 is rotatably connected to the middle of the lubricating oil feed chamber 22. The shaft of the rotating handle 41 is fixedly connected to the detection structure 5. The lower part of the driving component 44 is slidably connected to a straight groove opened in the inner wall of the lubricating oil feed chamber 22. One end of the driving component 44 is rotatably connected to the end of the linkage rod 42. The other end of the driving component 44 is rotatably connected to one end of the hinge rod 45. The other end of the hinge rod 45 is rotatably connected to the end of the control component 43.
[0037] The control component 43 further includes: a sliding handle 431 and a limiting rail 432. The side of the control component 43 is fixedly connected to the end of the sliding handle 431. The sliding handle 431 is slidably connected to the groove of the limiting rail 432. The end of the limiting rail 432 is fixedly connected to the inner wall of the lubricating oil feed chamber 22.
[0038] The driving component 44 further includes: a guide wheel 441 and a suction head 442. The lower part of the driving component 44 is fixedly connected to the middle part of the guide wheel 441. The column at the lower part of the guide wheel 441 is slidably connected to the straight groove opened in the lubricating oil feed chamber 22. The end of the driving component 44 is fixedly connected to the suction head 442.
[0039] Lubricating fluid is delivered from the inlet of the lubricating oil feed hopper 22 to the dispensing structure 4. Then, when the steel cable initially passes through the steel cable through-hole 21, the detection structure 5 drives the rotating handle 41 to rotate. As the rotating handle 41 rotates, the disc at its end abuts against the guide wheel 441, causing the guide wheel 441 to move towards the control component 43. Because the lower column of the guide wheel 441 is slidably connected to the straight groove of the lubricating oil feed hopper 22, the movement of the guide wheel 441 is more stable. At this time, the linkage rod 42 connected to the drive component 44 will pull other drive components 44 to move accordingly. At this time, the drive component 44... 4. The connection between the hinge rod 45 and the control member 43 will move toward the position of the control member 43. At this time, the connection between the hinge rod 45 and the control member 43 will open, creating a gap in the control member 43. At this time, the suction head 442 will extend from the opening slot of the steel cable through hole 21. The lubricant adsorbed on the suction head 442 will be applied to the steel wire. When the drive member 44 is reset, the drive member 44 will drive the suction head 442 to reset. At this time, the sliding handle 431 fixedly connected to the control member 43 will slide under the restriction of the limit track 432, causing the control member 43 to reset. At this time, the space opened by the control member 43 will close again to prevent the lubricant from flowing out.
[0040] By setting the feeding structure 4, the outer wall of the steel cable can be coated with lubricant, which avoids excessive friction when the steel cable passes through the steel cable through hole 21 due to the dry outer wall, making it difficult for the steel cable to pass through the steel cable through hole 21. In addition, the control component 43 can also dispense a fixed amount of lubricant to avoid excessive dispensing and waste.
[0041] As a further embodiment of the present invention, the detection structure 5 includes: a connecting cylinder 51, a toggle head 52, a friction element 53, and a friction ring 531. The end of the connecting cylinder 51 is fixedly connected to the shaft of the rotating handle 41, the inner wall of the connecting cylinder 51 is slidably connected to the toggle head 52, the end of the toggle head 52 is fixedly connected to one end of the friction element 53, and the other end of the friction element 53 is fixedly connected to the end of the friction ring 531.
[0042] The connecting cylinder 51 further includes: a spring 512 and a curved groove 513. The inner wall of the connecting cylinder 51 is provided with a curved groove 513, which is slidably connected to the protrusion on the outer wall of the actuating head 52. The middle part of the connecting cylinder 51 is provided with a spring 512.
[0043] The actuating head 52 further includes: a rotating cylinder 521 and a power handle 522. The middle part of the actuating head 52 is fixedly connected to the end of the rotating cylinder 521, and the inner wall of the rotating cylinder 521 is rotatably connected to the end of the power handle 522.
[0044] Because the rod of friction element 53 is slidably connected to the opening slot of the cable through hole 21, when the cable initially enters the cable through hole 21, the cable will drive the friction ring 531 to move under excessive friction. This causes the friction ring 531 to drive the power handle 522 to move through the friction element 53. The power handle 522 will apply pressure to the actuating head 52, causing the actuating head 52 to slide towards the curved groove 513. At this time, the protrusion on the outer wall of the actuating head 52 will abut against the curved groove 513 during the movement, causing the curved groove 513 to drive the connecting cylinder 51 to rotate. Because the end of the connecting cylinder 51 is fixedly connected to the rotating handle 41, the connecting cylinder 51 will drive the rotating handle 41 to rotate. When the cable can no longer apply friction to the friction ring 531, the spring 512 will drive the actuating head 52 to reset.
[0045] The detection structure 5 is driven by the friction generated when the steel cable passes through the steel cable hole 21. The detection structure 5 controls the feeding structure 4 to release lubricant to lubricate the steel cable. When the friction of the steel cable is small, it means that the steel cable does not need lubrication. At this time, the detection structure 5 will not operate and will not control the feeding structure 4 to lubricate the steel cable. Thus, the detection structure 5 controls whether the feeding structure 4 needs to lubricate the steel cable based on the magnitude of the friction of the outer wall of the steel cable.
