Description

Technical Field

[0001] This invention relates to the field of building technology, and in particular to a rapid anchoring device for precast box girders. Background Technology

[0002] In bridge engineering, the construction of prestressed steel strands is extremely important. During the construction of transverse prestressed steel strands in the top slab of a precast box girder, tensioning is required. Therefore, tensioning grooves must be reserved during the concrete pouring at the flange edge, creating a sawtooth shape at the flange edge. After tensioning, the flange edge of the precast box girder is then sealed with anchors. Anchor sealing refers to the process of sealing and fixing the anchored portion of the anchor rod to the surrounding soil or rock after the anchor rod construction is completed. This process is typically used to protect the anchor rod from environmental erosion and damage, and to ensure its long-term stability. The specific steps and methods of anchor sealing may vary depending on the specific construction conditions and requirements, but generally include the following main steps: Cleaning the anchor rod: Clean the installed anchor rod to ensure its surface is clean, free of oil and debris. Grouting: Use grouting equipment to inject grouting material into the anchor rod holes and the surrounding soil or rock. The selection of grouting material should be determined based on specific engineering requirements and geological conditions. The quality and effectiveness of anchor sealing are crucial to the service life and stability of the anchor rod. Therefore, when carrying out anchor sealing operations, the relevant technical specifications and construction requirements should be strictly followed, and quality control of the construction process should be ensured.

[0003] Existing technologies still have shortcomings in the anchor sealing process. For example, a sealing box for prestressed anchor heads of box girders, patent number CN201720387882.0, includes: a baffle, which is rectangular in shape and vertically arranged, with a first through hole at its upper part; a guide tube, one end of which is connected to the first through hole and inclined upward, located on one side of the baffle; and a pair of upper limit feet, which are perpendicular to the baffle and arranged on the other side of the baffle, with the pair of upper limit feet located on the same horizontal plane and respectively located in the first through hole. On both sides of the hole, the end where the upper limit foot intersects with the baffle is located at the top of the first through hole, and the end of the upper limit foot away from the baffle is provided with a second through hole; a pair of first fasteners are detachably connected to a pair of upper limit feet respectively through the second through hole; a pair of lower limit feet are set perpendicular to the baffle at the bottom of the baffle on the same horizontal plane, and the lower limit feet and the upper limit feet are located on the same side of the baffle. It cannot simultaneously seal the anchor rod in the anchor hole and the anchor rod that extends to the end wall of the box girder, which greatly limits its application. Summary of the Invention

[0035] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0036] Example 1: Reference Figure 1-13 A rapid anchoring device for precast box girders is characterized by comprising: a lifting device 1, a horizontal moving device 2, a chiseling mechanism 3, a moving mechanism 4, a telescopic mechanism 5, an auxiliary motor 6, and a mold cylinder assembly 7. The lifting device 1 is equipped with the horizontal moving device 2, and the chiseling mechanism 3 and the moving mechanism 4 are spaced apart on the horizontal moving device 2. The moving mechanism 4 is equipped with the telescopic mechanism 5, the auxiliary motor 6, and the mold cylinder assembly 7. The auxiliary motor 6 is slidably connected to the moving mechanism 4, and the output end of the auxiliary motor 6 is in rolling cooperation with the telescopic mechanism 5. The output end of the telescopic mechanism 5 is connected to one end of the mold cylinder assembly 7, and the other end of the mold cylinder assembly 7 is used to anchor the anchor rod.

[0037] The working process and beneficial effects of the above technical solution are as follows:

[0038] The device is placed at the end of the box girder. The lifting device 1 is controlled to rise or fall a certain distance according to the required anchoring position. When the horizontal moving device 2 is parallel to the required anchoring position, the horizontal moving device 2 moves to the required anchoring position, improving the accuracy of the device displacement. The horizontal moving device 2 drives the chiseling mechanism 3 to chisel the required anchoring position. After chiseling, the horizontal moving device 2 drives the moving mechanism 4 to move to the required anchoring position. The telescopic mechanism 5 on the moving mechanism 4 drives the mold cylinder assembly 7 to align with the anchoring position and fit against the concrete bonding surface, and then the anchoring is performed. The mold cylinder assembly 7 can be used to anchor the end wall of the box girder or the anchor hole, improving the applicability of the device. After the anchoring is completed, the telescopic mechanism 5 and the auxiliary motor 6 are rolled together to facilitate the separation of the mold cylinder assembly 7 from the anchoring position, improving the automation effect of the device.

[0039] This invention has been implemented in the road and integrated utility tunnel project of Huaihe Road, Ziyun Road, and Hangying Road in Chengnan New District of Fuyang City, and has achieved a high-efficiency and rapid sealing effect.

[0040] The mold cylinder assembly 7 includes: a guide plate 8, a cylinder 9, a guide rod 10, and a pressure plate 11. The guide plate 8 is connected to the moving mechanism 4. One side wall of the guide plate 8 is fitted against the side wall of the box girder. One end of the cylinder 9 is slidably connected inside the guide plate 8. The other end of the cylinder 9 is connected to the output end of the telescopic mechanism 5. The guide rod 10 is slidably connected to the through hole of the output end of the telescopic mechanism 5. The end of the guide rod 10 is threadedly connected to one side wall of the pressure plate 11. The other side wall of the pressure plate 11 forms a sealing and anchoring cavity with the inner wall of the cylinder 9. The top side wall of the cylinder 9 is provided with a grouting port communicating with the sealing and anchoring cavity. The side wall of the cylinder 9 is inserted into the anchor hole. A circular hole is opened on the pressure plate 11. A guide groove is opened on both the upper and lower inner walls of the circular hole. The end wall of the guide groove is filled with a grouting port. The hydraulic spring is connected to the end of the grouting plate 50. The other end of the grouting plate 50, located outside the sealing cavity, has a hemispherical groove. The other ends of the two grouting plates 50 are fitted together for sealing. The two hemispherical grooves form a spherical groove, which facilitates grouting at the output end of the grouting equipment. Since both grouting plates 50 are slidably connected in the grooves on both sides of the circular hole, the sealing effect during grouting is improved. After the concrete has solidified, the cylinder 9 is completely removed from the anchor hole. By setting the telescopic mechanism 5 to work with the cylinder 9, it is convenient for the device to seal different anchoring points, which improves the applicability of the mechanism. It is also convenient to clean the residual concrete inside the cylinder 9 after the anchoring is completed, and to apply the release agent before the anchoring begins.

[0041] The working process and beneficial effects of the above technical solution are as follows:

[0042] When the anchoring point of the mold cylinder assembly 7 is the end wall of the box girder, the moving mechanism 4 is activated to move towards the end wall of the box girder, so that the guide plate 8 fits against the end wall of the box girder. The cylinder 9 is fitted onto the end of the anchor rod, and concrete is injected from the grouting port of the cylinder 9. After the grouting is completed, the guide rod 10 drives the pressure plate 11 to compact the concrete. The pressure of the guide rod 10 can be maintained by an external cylinder or by applying a constant pressure at the end of the guide rod 10. After the concrete solidifies, the guide rod 10 is removed from the pressure plate 11, and the sliding auxiliary motor 6 is moved so that its position is parallel to the output end side wall of the telescopic mechanism 5 at the end of the cylinder 9. The guide wheel is used to rotate the motor, so that the cylinder 9 is separated from the anchoring point.

[0043] When the anchoring point of the mold cylinder assembly 7 is the anchor hole on the end wall of the box girder, the moving mechanism 4 is activated to move towards the end wall of the box girder, so that the guide plate 8 is in contact with the end wall of the box girder. The telescopic mechanism 5 is activated to insert the cylinder 9 into the anchor hole, and concrete is injected from the grouting port of the cylinder 9. The pressure plate 11, which is threadedly connected to the guide rod 10, is kept parallel to the guide plate 8. After grouting, the moving mechanism 4 is activated to move away from the end wall of the box girder. Due to the movement of the cylinder 9, the volume occupied by the cylinder 9 in the anchor hole will decrease, and the corresponding concrete height will decrease to a certain extent. The output pipe of the grouting equipment is passed through the grouting port and then through the pressure plate 11. The output pipe of the grouting equipment contacts the spherical grooves on the sidewalls of the two grouting plates 50 through the round hole on the top, and pushes the two grouting plates 50 into the grooves they are in. Then the output pipe extends into the sealing and anchoring cavity to grout. After the sealing and anchoring is completed, the guide rod 10 is removed from the pressure plate 11, the auxiliary motor 6 is slid so that its position is parallel to the output sidewall of the telescopic mechanism 5 at the end of the cylinder 9, and the guide wheel is used to rotate it so that the cylinder 9 is separated from the sealing and anchoring point. This improves the rationality of the mechanism design, avoids the concrete liquid level from dropping due to the cylinder 9 moving out of the anchoring hole, thus avoiding poor sealing and anchoring effect, and avoids the cumbersome secondary operation.

[0044] The telescopic mechanism 5 includes: a mounting plate 12, a guide plate 13, and a steering ring 14. The end of the cylinder 9 is coaxially connected to the end face of the mounting plate 12. An annular groove is opened on the other end face of the mounting plate 12. The guide plate 13 is slidably connected in the annular groove. The end of the guide plate 13 is connected to the output end of the cylinder. The cylinder is installed on the end face of the moving mechanism 4. A guide rod 10 is slidably connected in the through hole of the mounting plate 12. The side wall of the mounting plate 12 is connected to the inner wall of the steering ring 14. The side wall of the steering ring 14 is in rolling cooperation with the side wall of the guide wheel at the output end of the auxiliary motor 6.

[0045] The working process and beneficial effects of the above technical solution are as follows:

[0046] The guide plate 13 is slidably installed in the annular groove of the mounting plate 12. The guide plate 13 is connected to the output end of the cylinder. The side wall of the steering ring 14 fitted on the mounting plate 12 can roll and cooperate with the guide wheel at the output end of the auxiliary motor 6. Since the guide plate 13 is located in the annular groove of the mounting plate 12, the cylinder can convert forward or backward movement into forward or backward movement of the mounting plate 12. When the side wall of the steering ring 14 rolls and cooperates with the guide wheel at the output end of the auxiliary motor 6, the guide plate 13 slides circumferentially in the annular groove of the mounting plate 12, which reduces the complexity of the mechanism and saves manufacturing costs.

[0047] The moving mechanism 4 includes a longitudinal slide 15, a slider 16, a rack 17, and a gear 18. The horizontal moving device 2 is provided with a chiseling mechanism 3 and a longitudinal slide 15 at intervals. The slider 16 is slidably connected in the longitudinal slide 15. A guide plate 8, a cylinder, and a drive motor are installed on the upper end face of the slider 16. The upper end face of the slider 16 is slidably connected to an auxiliary motor 6. The output end of the drive motor is connected to a gear 18. The gear 18 meshes with the rack 17 for transmission. The side wall of the rack 17 is connected to the side wall of the longitudinal slide 15.

[0048] The working process and beneficial effects of the above technical solution are as follows:

[0049] The horizontal moving device 2 is provided with a longitudinal slide groove 15, and a slider 16 is slidably connected in the longitudinal slide groove 15. The slider 16 is connected to a guide plate 8, a cylinder and a drive motor. The output gear 18 of the drive motor meshes with the rack 17, so that the rotation of the drive motor is converted into the longitudinal movement of the slider 16. This makes it easier for the end of the mold cylinder assembly 7 on the slider 16 to fit against the end wall of the box girder, thereby increasing the stroke of the mechanism. The installation method of the drive motor saves space in the mechanism.

[0050] The horizontal moving device 2 includes: a mounting plate 19, a transverse slide 20, and a screw 21. The lifting device 1 is connected to the mounting plate 19. The upper end face of the mounting plate 19 is provided with a transverse slide 20 and a horizontal motor. A horizontal slider is slidably connected to the transverse slide 20. One end of the screw 21 is connected to the output end of the horizontal motor. The screw 21 is rotatably installed in the through hole of the transverse slide 20. The other end of the screw 21 is rotatably connected to the inner end wall of the transverse slide 20. The screw 21 is threadedly connected to the horizontal slider. A chiseling mechanism 3 and a longitudinal slide 15 are connected at intervals on the upper end face of the horizontal slider.

[0051] The working process and beneficial effects of the above technical solution are as follows:

[0052] The lifting device 1 is equipped with a mounting plate 19, and a horizontal slide groove 20 is provided on the mounting plate 19. When the horizontal motor rotates forward, it drives the screw 21 to rotate forward. The horizontal slider that is threaded to the screw 21 moves to the left in the slide groove 20. When the horizontal motor rotates in reverse, it drives the screw 21 to rotate in reverse. The horizontal slider that is threaded to the screw 21 moves to the right in the slide groove 20, which improves the movement efficiency of the device.

[0053] The lifting device 1 includes: a mounting base 22, a lifting screw 23, and guide columns 24. The mounting base 22 is equipped with a lifting motor. The output end of the lifting motor is connected to one end of the lifting screw 23. The other end of the lifting screw 23 extends to the upper surface of the mounting base 22. The lifting screw 23 is threadedly connected to a threaded hole at one end of the mounting plate 19. The upper surface of the mounting base 22 is connected to the bottom end of a plurality of guide columns 24. The guide columns 24 are slidably engaged with the through holes at the other end of the mounting plate 19.

[0054] The working process and beneficial effects of the above technical solution are as follows:

[0055] The lifting motor inside the mounting base 22 rotates forward, driving the lifting screw 23 to rotate forward. The mounting plate 19, which is threadedly connected to the lifting screw 23, rises and slides upward along the guide post 24. When the lifting motor reverses, it drives the lifting screw 23 to rotate in reverse, causing the mounting plate 19, which is threadedly connected to the lifting screw 23, to fall and slide downward along the guide post 24, thus improving the lifting effect of the mechanism.

[0056] Example 2: Reference Figure 1-13 The chiseling mechanism 3 includes: a second moving mechanism 25, a turntable 26, an air guide slider 27, a grinding arm 28, a third moving mechanism 29, a drive motor 30, an air guide assembly 31, and a gear ring 49. The second moving mechanism 25 is the same mechanism as the moving mechanism 4. The second moving mechanism 25 is provided on the upper surface of the mounting plate 19. A mounting ring is connected to the second moving mechanism 25. The turntable 26 is rotatably connected in the annular groove of the mounting ring. An air guide slider 27 is slidably connected in each of the two slots on the turntable 26. One end of the air guide slider 27... The grinding arm 28 is connected to the end of the grinding arm 28. The other end of the air guide slider 27 is connected to the suction device through the air guide assembly 31. The bottom end of the air guide assembly 31 is connected to the upper end face of the second moving mechanism 25. The other end of the grinding arm 28 is in frictional engagement with the side wall of the box girder. The side wall of the grinding arm 28 is in frictional engagement with the inner wall of the anchor hole of the box girder. The turntable 26 is provided with a third moving mechanism 29 for driving the grinding arm 28 to move. The side wall of the turntable 26 is coaxially connected to the gear ring 49. The gear ring 49 is driven by the drive motor 30 through gear meshing. The drive motor 30 is set on the second moving mechanism 25.

[0057] The working process and beneficial effects of the above technical solution are as follows:

[0058] Before the device seals the anchor, the concrete bonding surface on the box girder end wall or anchor hole needs to be roughened. When the anchoring point is located on the box girder end wall, the third moving mechanism 29 is activated, so that the two grinding arms 28 are symmetrically set with the anchor rod end as the center. Then, the second moving mechanism 25 is activated to move the end of the grinding arm 28 towards the box girder end wall until it contacts the box girder end wall. The drive motor 30 is activated, and the rotation of the drive motor 30 drives the rotation of the gear ring 49. The gear ring 49 drives the turntable 26 to rotate, and the air guide slider 27 on the turntable 26 drives the grinding arm 28 to rotate. The end of the grinding arm 28 roughens the box girder end wall. At the same time, the suction device provides negative pressure to the end of the grinding arm 28 through the air guide component 31 and the air guide slider 27. While roughening, the debris and dust generated by roughening the box girder end wall are sucked out, which improves the sanitary environment of the construction site and protects the health of the operators. At the same time, the roughening of the grinding arm 28 improves the concrete bonding effect at the box girder end wall anchoring point.

[0059] The grinding arm 28 includes: a housing 32, an insert 33, a sleeve 34, an air extraction pipe 35, an air guide plate 36, a transverse suction component 37, a grinding column 38, an auxiliary rack 39, and an adjusting gear 40. One end of the air guide slider 27 is connected to the end of the air guide plate 36, and the other end of the air guide plate 36 is inserted into the housing 32. The upper and lower end faces of the air guide plate 36 are respectively connected to the bottom end of a bent pipe. The output end of the bent pipe is rotatably sealed to one end of the insert 33. An adjusting gear 40 is connected to the insert 33. The adjusting gear 40 meshes with the auxiliary rack 39 for transmission. 39 is detachably installed on the mounting hole of the turntable 26. The insertion tube 33 is inserted into the other end of the housing 32 and connected to the transverse suction member 37. The suction end of the transverse suction member 37 extends out to the outside of the end wall of the housing 32. The insertion tube 33 is fitted inside the sleeve 34. Multiple suction tubes 35 are equidistantly connected to the side wall of the sleeve 34. The end of the suction tube 35 extends out to the outside of the side wall of the housing 32. Multiple through holes equidistantly opened on the side wall of the insertion tube 33 are connected and cooperate with the suction tube 35. Multiple grinding pillars 38 are equidistantly provided on the side wall of the housing 32. The suction end of the suction tube 35 is set towards the grinding pillar 38.

[0060] The working process and beneficial effects of the above technical solution are as follows:

[0061] Before roughening, the position of the auxiliary rack 39 on the turntable 26 is adjusted so that it is located on both sides of the housing 32. The third moving mechanism 29 is activated to increase the distance between the two housings 32, so that the adjusting gear 40 meshes with the auxiliary rack 39. The rotation of the adjusting gear 40 drives the insertion tube 33 to rotate inside the sleeve 34, so that the through hole on the insertion tube 33 is connected to the air extraction pipe 35 that connects to the side wall of the sleeve 34. At the same time, the transverse suction component 37 connected to the sleeve 34 is connected. After roughening begins, the grinding column 38 roughens the side wall of the anchor hole. Simultaneously, the suction device is activated. The negative pressure of the suction device, through the air guide assembly 31, air guide slider 27, air guide plate 36, bend pipe, insertion pipe 33, air extraction pipe 35, and transverse suction component 37, sucks up the debris and dust generated during the roughening process, improving the linkage effect of the structure. While suctioning the side and inner walls of the anchorage, the end wall of the box girder can also be roughened separately, and debris and dust can be sucked up, improving the adaptability of the mechanism to roughening at different anchoring points. It can efficiently handle the anchoring joint, improving work efficiency.

[0062] The transverse suction component 37 includes: a guide tube 41, a guide groove tube 42, an installation tube 43, a gas guide groove 44, an auxiliary suction tube 45, and a second grinding column 46. One end of the insertion tube 33 is connected to the end of the guide tube 41, and the other end of the guide tube 41 is in frictional engagement with the guide groove tube 42. The guide groove tube 42 is installed inside the installation tube 43. The end of the installation tube 43 is connected to the inner end wall of the housing 32 through a return spring. The side wall of the installation tube 43 is connected to one end of the auxiliary conduit. The other end of the auxiliary conduit is slidably installed in the gas guide groove 44. The side wall of the gas guide groove 44 is slidably sealed to the other end of the auxiliary conduit. The other side wall of the gas guide groove 44 is connected to one end of the second installation tube. Multiple auxiliary suction tubes 45 are equidistantly connected on the side wall of the second installation tube. The ends of the auxiliary suction tubes 45 extend to the outer end wall of the housing 32. Multiple second grinding columns 46 are equidistantly arranged on the outer end wall of the housing 32. The ends of the auxiliary suction tubes 45 are oriented toward the second grinding columns 46.

[0063] The working process and beneficial effects of the above technical solution are as follows:

[0064] When the insertion tube 33 rotates, the guide tube 41 connected to it rotates synchronously. The end of the guide tube 41 disengages from the end of the guide groove tube 42, and the protrusion at the end of the guide tube 41 contacts the protrusion of the guide groove tube 42. The guide groove tube 42 pushes out a certain distance, and the guide groove tube 42 drives the installation tube 43 to move a certain distance. The auxiliary guide tube on the side wall of the installation tube 43 slides in the air guide groove 44 and communicates with the second installation tube connected to the air guide groove 44, and communicates with the auxiliary suction tube 45 on the second installation tube. When the device performs suction, the transverse suction component 37 can perform suction work simultaneously with the suction tube 35. By setting the transverse suction... The suction component 37 enhances the suction effect of the device, enabling suction of dead corners within the anchorage and also of the sealing anchorage on the end wall of the box girder. Through the rotational cooperation of the guide tube 41 and the guide groove tube 42, the rotation of the guide tube 41 is converted into the linear motion of the guide groove tube 42. After suction is completed, the residual debris in the pipe can be vibrated, facilitating timely cleaning of the debris during the next suction and preventing blockage caused by debris accumulation. The contact end between the guide tube 41 and the guide groove tube 42 can squeeze and grind some of the debris, grinding large-diameter debris into small-diameter debris, making it easier for the debris to be suctioned and processed.

[0065] The third moving mechanism 29 includes a third motor 47 and a guide block 48. The third motor 47 is connected to one side wall of the turntable 26. The output end of the third motor 47 extends to the other side wall of the turntable 26 and is connected to a screw. A screw block is threaded onto the screw. A guide block 48 is inclinedly connected to each side wall of the screw block. The included angle between the front side walls of the two guide blocks 48 is set at an acute angle. The guide blocks 48 are slidably connected in the grooves on the side wall of the housing 32.

[0066] The working process and beneficial effects of the above scheme are as follows:

[0067] The forward rotation of the third motor 47 drives the forward rotation of the screw. Guide blocks 48 are installed on both sides of the screw block that is threadedly connected to the screw. The included angle between the front sidewalls of the two guide blocks 48 is set at an acute angle. When the screw block moves forward, the two guide blocks 48 slide in the grooves on the sidewalls of the housing 32, and the two housings 32 move towards each other. When the reverse rotation of the third motor 47 drives the screw to reverse, the screw block moves backward, and the two guide blocks 48 drive the two housings 32 to move in opposite directions. This optimizes the structural design and reduces the addition of mechanical parts.
