Description

Technical Field

[0001] The invention belongs to the technical field of prestressed anchor rod construction, and in particular relates to a prestressed anchor rod positioning construction embedded device and a use method thereof. Background Art

[0002] Prestressed anchors consist of anchor heads, rod bodies and pads. The anchoring force generated by the anchor heads applies a certain pre-compressive stress to the surrounding rock, actively reinforcing the surrounding rock. Depending on the anchoring method or anchoring material, commonly used prestressed anchors include mechanical expansion shell prestressed anchors, resin prestressed anchors, and cement sleeve prestressed anchors. The stress actively applied to the surrounding rock of the tunnel by the installation machinery during the installation process is called the prestress of the anchor support. Anchors that can apply prestress are called prestressed anchors. The prestress of the anchor support is formed by the tension of the anchor rod body and the action on the rock mass in the anchoring area through the tray and the anchoring end. At this time, the axial tension borne by the anchor rod body is the anchor preload force.

[0003] During the positioning construction of prestressed anchor rods, they are directly pushed into the anchor rod pre-embedded holes through anchor rod pushing equipment, and then concrete is injected into the anchor rod pre-embedded holes outside the anchor rods and vibrated to make the concrete dense, thereby ensuring the normal prestressing tension of the anchor rods. Then, when the anchor rods are pushed into the anchor rod pre-embedded holes, there is a lack of auxiliary construction devices for positioning the prestressed anchor rods. Therefore, the prestressed anchor rods are prone to shaking and dislocation during the pushing process, and even centrifugal phenomena occur between the pre-embedded holes. This will lead to the problem of different concrete thickness between the outside of the anchor rod and the inner wall of the pre-embedded hole when concrete is injected after the anchor rods are pre-embedded, which will lead to the failure of the tension balance of the anchor rod pre-tightening force of the prestressed anchor rods. Summary of the invention

[0004] The object of the present invention is to provide a prestressed anchor rod positioning construction pre-embedded device and a method of using the same, so as to solve the problem that the anchor rod proposed in the above-mentioned background technology lacks a positioning construction auxiliary device for the prestressed anchor rod when it is pushed into the anchor rod pre-embedded hole. Therefore, the prestressed anchor rod is prone to shaking and dislocation during the pushing process, and even centrifugal phenomenon occurs between the pre-embedded holes, which will lead to the problem of uneven concrete thickness between the outside of the anchor rod and the inner wall of the pre-embedded hole when concrete is injected after the anchor rod is pre-embedded, which will lead to the problem of failure of the tension balance of the anchor rod pre-tightening force of the prestressed anchor rod.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a prestressed anchor rod positioning construction embedded device, comprising two fixed bases, the fixed base is pierced with two ground nails, the upper surface of the fixed base is fixedly installed with side support plates, the two side support plates are rotatably installed with a rotating shaft, a middle construction frame is fixed between the two rotating shafts, a top construction frame is fixedly installed on the upper surface of the middle construction frame, and a bottom construction frame is movably arranged on the lower surface of the middle construction frame, a rotating disk is fixedly installed on the end of one of the rotating shafts, a plurality of locking grooves are opened on the outer surface of the rotating disk, a locking shell is fixedly installed on the side of the side support plate on the same side of the rotating disk, a sliding plate is slidably installed inside the locking shell, a locking rod is fixedly installed on the upper surface of the sliding plate, the locking rod slides through and extends out of the locking shell and is used in conjunction with the locking groove, an operating channel is opened on the side of the locking shell, and an operating handle located in the operating channel is fixedly installed on the side of the sliding plate. The cam is provided with a plurality of camshafts, each of which ...

[0006] By adopting the above scheme, the whole device can be fixed on the horizontal plane by setting a fixed base and a ground nail. The rotating shaft, the turntable and the locking shell can be used to adaptively adjust the orientation angles of the middle construction frame, the top construction frame and the bottom construction frame according to the inclination of the construction surface of the anchor hole. The sprocket and the chain can be used in conjunction with the sliding plate and the tensioning wheel to clamp and fix the anchor in the center, so as to ensure that the anchor has good stability when inserted into the embedded hole and there will be no shaking, displacement or misalignment. It can also ensure that the thickness of the concrete slurry outside the anchor is uniform during grouting after the anchor is installed, thereby ensuring a good anchor preload force. By setting an adjusting shell and an adjusting plate for use in conjunction, the position of the bottom construction frame can be adaptively adjusted, so that the tensioning plate can be inserted into the anchor hole, and a two-way screw can be used in conjunction so that the tensioning plate can be tightened inside the end of the anchor hole, so as to avoid the problem of collapse of the end of the anchor hole and improve the operation stability.

[0007] In the above solution, it should be noted that both the motor 1 and the motor 2 are electrically connected to an external power source.

[0008] As a preferred embodiment, a plurality of guide blocks are fixedly installed on the side of the sliding plate, a plurality of guide rods are fixedly installed inside the locking shell, the guide block is slidably installed on the outer surface of the guide rod at the same side, a spring is fixedly installed between the guide block and the inner wall of the locking shell, two insertion holes are provided on the locking shell, a pin is inserted into one of the insertion holes, and a slot for inserting the pin is provided on the side of the sliding plate.

[0009] When the above scheme is adopted, when the guide block 1 and the guide rod 1 are cooperated with the spring 1, the sliding plate 1 will drive the guide block 1 to slide on the surface of the guide rod 1. Therefore, the guide rod 1 and the guide block together achieve a supporting and guiding effect, so that the sliding plate 1 has good sliding stability and is not prone to tilting and shaking. When the sliding plate 1 moves downward to drive the locking rod out of the locking groove, the spring 1 will deform. Therefore, the reverse force of the spring 1 can achieve a quick reset effect of the locking rod, thereby improving the convenience of operation. The use of the latch can achieve lateral limitation of the sliding plate to avoid accidental movement and improve the stability of the use effect.

[0010] As a preferred embodiment, the front and rear sides and the left and right sides of the top construction frame are fixedly installed with limiting slides, the sides of the support plate are provided with limiting slide grooves, and the limiting slides are slidably installed on the inner walls of the limiting slide grooves at corresponding positions.

[0011] By adopting the above scheme, the limiting slide plate is used to slide in the limiting slide groove, so as to provide limiting support for the horizontal movement of the support plate, improve the movement stability and prevent shaking.

[0012] As a preferred embodiment, two limiting rings are fixedly mounted on the outer surface of the support roller, and the two limiting rings are respectively arranged on the upper and lower side surfaces of the support plate.

[0013] By adopting the above solution, the limiting ring has a limiting effect to prevent the supporting roller from escaping from the inclined slideway on the supporting plate.

[0014] As a preferred embodiment, a guide block 2 is fixedly installed on the side of the sliding plate 2, and a guide rod 2 is slidably installed on the guide rod 2, the guide rod 2 is fixedly installed on the side of the top construction frame, and a spring 2 is fixedly installed between the guide block 2 and the top construction frame.

[0015] By adopting the above scheme, the guide rod 2 and the guide block 2 are used together to support and guide the horizontal movement of the sliding plate 2, thereby improving the smoothness of the movement. The spring 2 can have a reset effect. When the sliding plate 2 drives the wheel seat and the tensioning wheel to move inward, the spring 2 is deformed. Therefore, when the fixing bolt is screwed out, the elastic force of the spring 2 can be used to drive the tensioning wheel to move outward quickly and reset, thereby improving the convenience of operation.

[0016] As a preferred embodiment, a fixing bolt is threadedly mounted on the knob, and a plurality of fixing thread grooves are formed on the surface of the mounting seat on the same side as the knob, and the fixing bolt is used in conjunction with the fixing thread grooves.

[0017] By adopting the above scheme, the fixing bolt is used in conjunction with the fixing thread groove, and the position of the knob can be locked after being rotated, thereby locking the sprocket, and then locking the chain and the support plate. The locking structure is simple and easy to operate.

[0018] As a preferred embodiment, an adjusting shell is fixedly installed on the side of the middle construction frame, a threaded rod is rotatably installed inside the adjusting shell, a motor 1 is fixedly installed on the surface of the adjusting shell, the output shaft of the motor 1 is fixedly connected to the threaded rod, a threaded plate 1 is threadedly installed on the outer surface of the threaded rod, a connecting block is fixedly installed on the side of the threaded plate 1, the connecting block extends out of the adjusting shell through a strip channel opened on the side of the adjusting shell and is fixedly installed with an adjusting plate, the bottom end of the adjusting plate is fixedly installed on the side of the bottom construction frame, a plurality of limit rods 1 are fixedly installed inside the adjusting shell, and the threaded plate 1 is slidably installed on the outer surface of the limit rod 1.

[0019] By adopting the above scheme, the threaded rod in the adjustment shell is used in conjunction with motor 1. When motor 1 is working, the threaded rod is driven to rotate, and then the threaded plate 1 is driven to move up and down, thereby driving the adjustment plate to move up and down through the connecting block, and then the position of the bottom construction frame is adjusted up and down. The limit rod has a supporting and limiting effect on the threaded plate 1, thereby avoiding centrifugal shaking when the threaded plate 1 moves.

[0020] As a preferred embodiment, a plurality of guide blocks three are fixedly installed on the side of the middle construction frame, a plurality of guide rods three are fixedly installed on the side of the bottom construction frame, and the guide rods three are slidably installed on the guide blocks three at corresponding positions.

[0021] By adopting the above scheme, the guide block three is used in conjunction with the guide rod three to support the up and down movement of the bottom construction frame, so that the bottom construction frame has good stability when moving up and down and is not prone to tilting and shaking.

[0022] As a preferred embodiment, a plurality of sliding channels are opened on the side of the bottom construction frame, and a limiting rod 2 is fixedly installed in the sliding channel, the sliding plate 3 passes through the sliding channel and is slidably installed on the outer surface of the limiting rod 2, and two assembly blocks are fixedly installed on the side of the bottom construction frame, one of the assembly blocks is fixedly installed with a motor 2 on the side, a bidirectional lead screw is rotatably installed between the two assembly blocks, the output shaft of the motor 2 is fixedly connected to the bidirectional lead screw, and the two sections of the threaded outer surfaces of the bidirectional lead screw are threadedly installed with a threaded plate 2, and the threaded plate 2 is fixedly installed on the two ends of the sliding plate at the corresponding positions.

[0023] By adopting the above scheme, motor 2 is used to drive the bidirectional screw to rotate, thereby driving the two threaded plates 2 to move relative to each other, and then driving the two clamping plates to move relative to each other through sliding plate 3. The setting of limit rod 2 can play a supporting effect on the movement of threaded plate 2, so that threaded plate 2 has good movement stability when moving.

[0024] A method for using a prestressed anchor rod positioning construction embedded device comprises the following steps: S1. Place the fixed base on the horizontal ground, and use a ground nail to penetrate the fixed base and drive it into the horizontal ground; Then the latch is passed through the insertion hole at the upper position and inserted into the slot on the sliding plate to realize the locking of the rotary disk; S3, start motor 1 to drive the threaded rod to rotate, and then drive the threaded plate 1 to drive the connecting block to move, thereby driving the bottom construction frame to move toward the anchor rod construction surface. When the fixed base 2 on the bottom construction frame fits the anchor rod construction surface, stop motor 1, and then penetrate the ground nail 2 through the fixed base 2 and drive it into the anchor rod construction surface. At this time, the two tightening plates will enter the anchor rod pre-embedded hole, and then start motor 2. Motor 2 will drive the bidirectional lead screw to rotate, and then drive the threaded plates 2 on both sides to move relatively apart, thereby driving the two tightening plates to move relatively apart through the sliding plate 3. When the tightening plate hits the inner wall of the anchor rod pre-embedded hole, stop motor 2. At this time, the end of the anchor rod pre-embedded hole is tightened to prevent collapse. S4. Pass the anchor rod through the top construction frame, the middle construction frame and the bottom construction frame in turn, then unscrew the bolt, turn the knob, drive the support plate to move through the transmission of the sprocket and chain, use the inclined slideway in conjunction with the support roller to make the four sliding plates move inward synchronously, and then drive the tensioning wheel to move inward through the wheel seat to contact the surface of the anchor rod to achieve the centering of the anchor rod, then screw in the fixing bolt to lock the position, and then start the anchor rod pre-embedded pushing equipment so that the anchor rod can enter the pre-embedded hole.

[0025] Compared with the prior art, the present invention has the following beneficial effects: 1. Accurate positioning and stable insertion: In the prior art, the anchor rod lacks an effective positioning auxiliary device when it is pushed into the embedded hole, which makes it very easy to shake, dislocate, and even become eccentric with the embedded hole during the advancement process. The present invention can firmly fix the entire device on a horizontal plane by carefully setting a fixed base and a ground nail. At the same time, by cleverly utilizing the coordinated operation of the rotating shaft, the turntable and the locking shell, the orientation angles of the middle construction frame, the top construction frame and the bottom construction frame can be flexibly and accurately adjusted according to the inclination of the construction surface of the anchor rod hole. In addition, the sprocket and the chain cooperate with the sliding plate 2 and the tensioning wheel to accurately center and clamp the anchor rod. In this way, the anchor rod has excellent stability when inserted into the embedded hole, effectively avoiding problems such as shaking, offset and dislocation, and greatly improving the accuracy of construction. In actual slope anchoring projects, traditional construction methods often cause uneven subsequent grouting due to anchor rod positioning deviations, affecting the anchoring effect; the present invention can ensure the precise positioning of the anchor rod, and ensure that the thickness of the external concrete slurry is uniform when grouting after the anchor rod is inserted, thereby providing a solid guarantee for good anchor rod preload and significantly improving the project quality.

[0026] 2. Preventing the collapse of the ends of the anchor holes: During the anchor construction process, the collapse of the ends of the anchor holes is a common and thorny problem, which is often difficult to be effectively solved by existing technologies. The present invention innovatively arranges an adjustment shell and an adjustment plate. Through the close cooperation of the two, the position of the bottom construction frame can be accurately adaptively adjusted to ensure that the tightening plate is smoothly inserted into the anchor hole. At the same time, by utilizing the coordinated work of the bidirectional lead screw and motor 2, the tightening plate can be firmly tightened inside the end of the anchor hole. This design fundamentally avoids the problem of collapse of the ends of the anchor holes, greatly improves the stability during the operation, and provides a strong guarantee for the smooth progress of the construction. When carrying out anchor construction in some areas with complex geological conditions, the advantages of this design are particularly obvious, which effectively reduces construction interruptions and safety hazards caused by hole wall collapse and improves construction efficiency.

[0027] 3. Improve the stability of component movement and the convenience of operation: The present invention greatly improves the stability of component movement and the convenience of operation in the design of multiple key parts. For example, a guide block 1 is set on the side of the sliding plate 1, a guide rod 1 is installed inside the locking shell, and a spring 1 is matched, so that the sliding plate 1 can slide smoothly and effectively avoid tilting and shaking. At the same time, the reverse force of the spring 1 can quickly reset the locking rod, and the latch can achieve reliable lateral limit of the sliding plate 1 to avoid its accidental movement, which significantly improves the convenience of operation and the stability of the use effect. The limiting slide plate of the top construction frame cooperates with the limiting slide groove of the support plate to effectively improve the stability of the horizontal movement of the support plate; the limiting ring on the outer surface of the support roller prevents it from leaving the inclined slideway, ensuring the reliability of movement. The guide block 2, guide rod 2 and spring 2 of the sliding plate 2 cooperate with each other, not only playing a good supporting and guiding role for the horizontal movement of the sliding plate 2, but also can use the elastic force of the spring 2 to drive the tensioning wheel to quickly reset when the fixing bolt is screwed out, further improving the convenience of operation.

[0040] The present invention also provides a method for using a prestressed anchor rod positioning construction embedded device, comprising the following steps: S1, place the fixed base 1 on the horizontal ground, and use the ground nail 2 to penetrate the fixed base 1 and drive it into the horizontal ground; S2, drive the operating handle downward to pull out the latch 28, at this time the sliding plate 10 is unlocked, the operating handle drives the sliding plate 10 to move downward, the sliding plate 10 drives the locking rod 11 to move downward to disengage from the locking groove on the turntable 8, then the latch 28 passes through the plug hole at the lower position and is inserted into the slot on the sliding plate 10, and when the sliding plate 10 moves downward, it drives the guide block 25 to slide on the surface of the guide rod 26, at this time the spring 27 is deformed, and at this time the turntable 8 is unlocked, the turntable 8 is rotated to drive the middle construction frame 5 to rotate through the rotating shaft 4, according to The inclination angle of the anchor rod construction inclined surface adjusts the inclination of the middle construction frame 5, the bottom construction frame 7 and the top construction frame 6 until the middle construction frame 5, the bottom construction frame 7 and the top construction frame 6 are just perpendicular to the anchor rod construction inclined surface, and then the latch 28 is pulled out. At this time, the sliding plate 10 will move upward and reset under the action of the spring 1 27, and then drive the locking rod 11 to move and insert into the locking groove to achieve the locking of the turntable 8. Then the latch 28 passes through the socket at the upper position and is inserted into the slot on the sliding plate 10 to achieve the locking of the sliding plate 10; S3, start the motor 1 36 to drive the threaded rod 37 to rotate, and then drive the threaded plate 1 38 to drive the connecting block 39 to move, thereby driving the bottom construction frame 7 to move toward the anchor rod construction surface. When the fixed base 21 on the bottom construction frame 7 fits with the anchor rod construction surface, stop the motor 1 36, and then penetrate the ground nail 22 through the fixed base 21 and drive it into the anchor rod construction surface. At this time, the two tightening plates 24 will enter the anchor rod pre-buried hole, and then start the motor 2 46. The motor 2 46 will drive the bidirectional screw 47 to rotate, and then drive the threaded plates 2 48 on both sides to move relatively apart, thereby driving the two tightening plates 24 to move relatively apart through the sliding plate 3 23. When the tightening plate 24 hits the inner wall of the anchor rod pre-buried hole, stop the motor 2 46. At this time, the end of the anchor rod pre-buried hole is tightened to prevent collapse. S4. Pass the anchor rod through the top construction frame 6, the middle construction frame 5 and the bottom construction frame 7 in turn, then unscrew the bolt, turn the knob 14, drive the support plate 16 to move through the transmission of the sprocket 13 and the chain 15, and use the inclined slideway in conjunction with the support roller 18 to make the four sliding plates 10 move inward synchronously, and then drive the tensioning wheel 20 to move inward through the wheel seat 19 to contact the surface of the anchor rod to achieve the centering of the anchor rod, and then screw in the fixing bolt 34 to lock the position, and then start the anchor rod pre-embedded pushing equipment so that the anchor rod can enter the pre-embedded hole.

[0041] In actual construction scenarios, the use method and implementation process of the prestressed anchor rod positioning construction embedded device are as follows: Installation and tilt angle adjustment: After selecting a suitable location at the construction site, the construction workers place the two fixed bases 1 on the horizontal ground to ensure that they are placed stably. Then, use tools to pass the ground nails 2 through the holes on the fixed base 1 in turn, and force them into the horizontal ground, so that the fixed base 1 is firmly connected to the ground, providing a stable support foundation for the entire device.

[0042] In areas with complex terrain or poor geological conditions, such as soft soil or ground with a lot of gravel, it may be necessary to first level and compact the ground to ensure that the fixed base 1 fits tightly with the ground and the ground nails 2 can be effectively fixed. At the same time, construction personnel can use tools such as a level to check the levelness of the fixed base 1 to ensure the accuracy of the device installation.

[0043] Next, according to the actual inclination angle of the anchor rod construction inclined surface, the inclination of the middle construction frame 5, the bottom construction frame 7 and the top construction frame 6 is adjusted. The construction personnel drive the operating handle in the operating channel on the side of the locking shell 9 downward to move the sliding plate 10 downward. In this process, the guide block 25 on the side of the sliding plate 10 slides smoothly on the surface of the guide rod 26 inside the locking shell 9, playing a good guiding role, and at the same time compressing the spring 27 to make it elastically deformed. The sliding plate 10 drives the locking rod 11 to move downward until the locking rod 11 is disengaged from the locking groove on the turntable 8. At this time, the latch 28 is pulled out from the upper socket of the locking shell 9, passed through the socket at the lower position and inserted into the slot on the side of the sliding plate 10, temporarily fixing the position of the sliding plate 10 to prevent it from moving accidentally.

[0044] During operation, the construction personnel can more accurately grasp the rotation angle and ensure the accuracy of adjustment by observing the angle mark on the turntable 8 or using an angle measuring tool. At the same time, for some construction scenes with high angle adjustment requirements, the angle of the turntable 8 can be fine-tuned multiple times until the ideal inclination is achieved.

[0045] After completing the above operations, the turntable 8 is in an unlocked state. The construction personnel rotate the turntable 8, and the turntable 8 drives the middle construction frame 5 to rotate through the rotating shaft 4, and then drives the bottom construction frame 7 and the top construction frame 6 to rotate synchronously. The construction personnel closely observe the relative angle between the construction inclined surface and the device, and stop rotating the turntable 8 when the middle construction frame 5, the bottom construction frame 7 and the top construction frame 6 are adjusted to be just perpendicular to the anchor rod construction inclined surface. At this time, pull out the latch 28, and the sliding plate 10 moves upward and resets under the elastic force of the spring 1 27, driving the locking rod 11 to insert into the locking groove of the turntable 8, thereby locking the turntable 8. Finally, insert the latch 28 again into the upper jack of the locking shell 9 and into the slot on the side of the sliding plate 10 to complete the locking of the sliding plate 10, ensuring that the inclination angle of the entire device is fixed, providing a stable foundation for subsequent construction.

[0046] Adjustment of the position of the bottom construction frame and tightening of the end of the anchor hole: After the device tilt angle adjustment is completed, start the motor 136 on the surface of the adjustment shell 35. The output shaft of the motor 136 drives the threaded rod 37 to rotate, and the threaded plate 138 threadedly installed on the outer surface of the threaded rod 37 moves along the axial direction of the threaded rod 37 under the rotation of the threaded rod 37. The connecting block 39 on the side of the threaded plate 138 moves with the threaded plate 138, and the connecting block 39 passes through the strip channel on the side of the adjustment shell 35, driving the adjustment plate 40 to move, thereby driving the bottom construction frame 7 to move toward the anchor construction surface.

[0047] During the movement of the bottom construction frame 7, the construction personnel can accurately control the movement distance of the bottom construction frame 7 by observing the distance between the bottom construction frame 7 and the anchor construction surface, combining the scale mark set on the adjustment shell 35 or using a distance measuring tool. At the same time, the speed of the motor 1 36 can be adjusted in time according to the actual situation on site to ensure that the bottom construction frame 7 is stably close to the anchor construction surface.

[0048] When the bottom construction frame 7 moves, the guide rod 3 43 on its side slides in the guide block 3 42 on the side of the middle construction frame 5, providing stable guidance and support for the movement of the bottom construction frame 7 to prevent it from deflecting or shaking. When the fixed base 21 on the bottom construction frame 7 fits tightly with the anchor rod construction surface, the motor 1 36 is stopped. The construction personnel use tools to drive the ground nail 22 through the perforation on the fixed base 21 and into the anchor rod construction surface to further fix the position of the bottom construction frame 7.

[0049] At this time, the two top tightening plates 24 inside the bottom construction frame 7 are already located inside the anchor rod pre-embedded hole. In order to prevent the end of the anchor rod pre-embedded hole from collapsing, the motor 2 46 on the side assembly block 45 of the bottom construction frame 7 is started. The output shaft of the motor 2 46 drives the bidirectional screw 47 to rotate, and the threaded plate 2 48 on the outer surface of the two sections of the thread of the bidirectional screw 47 moves relatively away along the axial direction of the bidirectional screw 47 under the rotation of the bidirectional screw 47. The threaded plate 2 48 is fixedly installed at the end of the sliding plate 3 23, driving the sliding plate 3 23 to slide in the sliding channel on the side of the bottom construction frame 7. The limit rod 2 44 in the sliding channel provides support and guidance for the movement of the sliding plate 3 23 to ensure smooth movement. The sliding plate 3 23 drives the two top tightening plates 24 to move relatively away. When the top tightening plate 24 is tightly against the inner wall of the anchor rod pre-embedded hole, the motor 2 46 is stopped to achieve the end of the anchor rod pre-embedded hole to be tightened, effectively preventing collapse.

[0050] During the tightening process, the construction personnel can judge whether the tightening force is appropriate by using the pressure sensor or observing the deformation of the tightening plate 24. If the tightening force is insufficient, the rotation time of the motor 2 46 can be appropriately increased; if the tightening force is too large, the motor 2 46 can be rotated in the reverse direction for fine adjustment to ensure the tightening effect while avoiding damage to the anchor bolt pre-buried hole.

[0051] Anchor rod centering and insertion: After completing the position adjustment of the bottom construction frame 7 and tightening the end of the anchor rod hole, the anchor rod centering and insertion operation is performed. The construction personnel pass the anchor rod through the top construction frame 6, the middle construction frame 5 and the bottom construction frame 7 in sequence. Then, unscrew the fixing bolt 34 on the knob 14 to release the lock of the knob 14. Turn the knob 14, and the knob 14 drives the sprocket 13 in the mounting seat 12 to rotate. Since the four sprockets 13 are connected by the chain 15, the rotation of one sprocket 13 drives the other sprockets 13 to rotate synchronously.

[0052] The support plate 16 on the upper surface of the sprocket 13 moves as the sprocket 13 rotates, and the inclined slideway on the support plate 16 cooperates with the support roller 18. The support roller 18 rolls in the inclined slideway, driving the sliding plate 17 to slide inward along the guide rod 32 on the side of the top construction frame 6, and the guide block 31 on the side of the sliding plate 17 slides on the guide rod 32 to ensure smooth movement and compress the spring 33 at the same time. The sliding plate 17 drives the tension wheel 20 to move inward through the wheel seat 19 until the tension wheel 20 evenly contacts the surface of the anchor rod to achieve the centering of the anchor rod.

[0053] During the centering process, the construction personnel can use a centering detection instrument, such as a laser centering instrument, to monitor the centering of the anchor rod in real time. If the anchor rod is found to be offset, the knob 14 can be fine-tuned in time to ensure that the centering accuracy of the anchor rod meets the construction requirements.

[0054] After the anchor is centered, screw the fixing bolt 34 into the fixed thread groove on the surface of the mounting seat 12 on the same side as the knob 14 to lock the knob 14, the sprocket 13 and the entire centering structure to prevent displacement during the insertion of the anchor. Finally, start the anchor pre-embedded pushing device, and under the guarantee of the stable centering structure and the tightened end of the anchor pre-embedded hole, insert the anchor smoothly and accurately into the pre-embedded hole to complete the positioning construction and pre-embedded work of the prestressed anchor.
