Description

Technical Field

[0001] The invention relates to a pier formwork climbing auxiliary device, belonging to the technical field of climbing formwork. Background Art

[0002] Climbing formwork systems (abbreviated as "climbing formwork") are critical equipment in the construction of tall concrete structures, such as bridge piers and core tubes. Integrating formwork, support, and climbing functions, they can ascend section by section along the poured concrete structure, significantly improving construction efficiency. A typical climbing formwork system typically includes formwork, a climbing mechanism (such as climbing rails or climbing rods), supporting trusses, and a multi-layered operating platform.

[0003] The climbing motion of a climbing formwork system relies on its secure connection to the pre-formed concrete structure. In standard construction, the climbing rails or attachment rods used for connection and guidance are usually pre-embedded during the pouring of the previous concrete section. This is the most common and efficient method.

[0004] However, in certain engineering scenarios, pre-embedding is not feasible and the "post-anchoring" technology must be used, that is, drilling holes in the hardened concrete surface and embedding anchor bolts to fix the climbing rails or attachments. These typical scenarios include:

[0005] Reinforcement and reconstruction of old bridge piers: When raising or increasing the cross-section of existing bridge piers, there are no embedded parts in the original structure, and the climbing formwork system can only be attached through post-anchoring.

[0006] Remedies for construction errors: In conventional construction, if embedded parts are missed or misplaced, post-anchor drilling must be used to remedy the situation.

[0007] In the above scenario where post-anchor drilling is required, the inventors discovered that the existing drilling operation method has serious technical defects:

[0008] Existing drilling methods typically involve manual handheld drilling or using a simple bracket to secure a water drill. When drilling at a higher location, beyond the operator's standing range, a common practice is to temporarily erect scaffolding or a ladder on the multi-layered operating platform of the climbing formwork. This seemingly simple "higher-up" operation method presents fatal safety hazards and efficiency bottlenecks:

[0009] High safety risks: The climbing formwork platform itself is an elevated working environment, with limited space and a restricted load capacity. Adding unstable scaffolding to the platform raises the operator's center of gravity even higher, further constricting their mobility. Handheld, vibrating water drills are prone to falls from height due to instability, scaffolding movement, or misoperation, exponentially increasing the risk.

[0010] Low efficiency and difficulty ensuring accuracy: Manually supporting the drilling machine on an unstable, high-altitude scaffolding is not only labor-intensive but also difficult to ensure accurate drilling angles and depths. Repeated positioning and calibration consumes significant time, directly impacting the overall progress of the climbing formwork construction. Summary of the Invention

The same end of the two transverse screw rods is connected to a driven sprocket, and the two driving sprockets are respectively connected to the driven sprocket through chains.

[0020] The longitudinal moving unit includes a longitudinal rod, a first sliding sleeve and a second sliding sleeve. The first sliding sleeve and the second sliding sleeve are slidably connected on the longitudinal rod. The upper end of the first sliding sleeve is connected to a water drill. The second sliding sleeve is provided with a second motor. The upper end of the longitudinal rod is fixedly connected to a longitudinal rack. A driving gear matched with the longitudinal rack is provided in the first sliding sleeve. The driving gear is coaxially connected to a driven pulley. The output end of the second motor is connected to a driving pulley. The driving pulley is connected to the driven pulley through a transmission belt.

[0021] A support rod is connected between the first sliding sleeve and the second sliding sleeve, and the support rod is adjustably connected to the first sliding sleeve or the second sliding sleeve for adjusting the distance between the first sliding sleeve and the second sliding sleeve;

[0022] Both ends of the longitudinal rod are movably connected to the transverse screw rod through transverse nuts.

[0023] The upper end of the drilling platform below the two horizontal screw rods is connected with a heavy-duty slide rail, and the lower end of the longitudinal rod is connected with a heavy-duty slide block matched with the heavy-duty slide rail.

[0024] The drilling platform is a square frame made of channel steel, with the channel steel opening arranged downwards. Both sides are made of a whole longitudinal channel steel, and a number of transverse channel steels are connected between the longitudinal channel steels.

[0025] The detection unit includes a horizontal detection component arranged at the upper end of the channel steel, and a distance detection component is respectively arranged in the notches at the front ends of the two channel steels.

[0057] Example

[0058] like Figures 1 to 11 As shown, the pier formwork climbing auxiliary device of the present invention includes:

[0059] A drilling platform 6 is provided with a transverse movement unit 2, a longitudinal movement unit 3, a water drill 4, a positioning unit 1, and a detection unit 5. The transverse movement unit 2 and the longitudinal movement unit 3 are respectively used to drive the movement of the water drill 4. The positioning unit 1 is used to ensure the stability of the drill bit at the output end of the water drill 4. The detection unit 5 is used to ensure the horizontality of the drilling platform 6 and the verticality of the drill bit at the output end of the water drill 4 relative to the outer wall of the pier.

[0060] The platform adjustment unit 7 is connected to the lower end of the drilling platform 6 and cooperates with the detection unit 5 to adjust the horizontality of the drilling platform 6 and the verticality of the drill bit at the output end of the water drill 4 relative to the outer wall of the pier;

[0061] The platform adjustment unit 7 includes an adjustment frame 73, one end of which is rotatably connected to a rotating shaft 71, a key on the rotating shaft 71 is connected to a rotating plate 72, and the adjustment frame 73 is hingedly connected to a vertical adjustment electric cylinder 74, the output end of the vertical adjustment electric cylinder 74 is hingedly connected to the rotating plate 72, and the rotation of the rotating shaft 71 can be controlled by the action of the vertical adjustment electric cylinder 74. The lower end of the drilling platform 6 is welded with a support plate 64 (such as Figure 7 As shown), a rotating sleeve 63 is fixed on the support plate 64, and the rotating sleeve 63 is key-connected to the rotating shaft 71.

[0062] like Figure 8 As shown, the platform adjustment unit 7 includes a connecting seat 78 bolted to the upper end of the lifting unit 8, the upper end of the connecting seat 78 is hinged to the lower end of the adjustment frame 73 through a hinge plate 75, the connecting seat 78 is located below the hinge plate 75 and is bolted to a horizontal adjustment plate 77, the horizontal adjustment plate 77 and the adjustment frame 73 are hingedly connected to a horizontal adjustment electric cylinder 76, and the horizontal adjustment electric cylinder 76 is actuated to control the adjustment frame 73 to rotate along the hinge point between the hinge plate 75 and the adjustment frame 73, thereby realizing the movement of the adjustment frame 73, thereby driving the drilling platform 6 to be horizontally adjusted.

[0063] like Figure 9 As shown, the end of the adjustment frame 73 away from the rotating shaft 71 is connected to the bull's eye bearing 731. The adjustment frame 73 provides enhanced support for the support plate 64 through the bull's eye bearing 731, preventing the gravity of the drilling platform 6 from acting entirely on the rotating shaft 71, thereby accelerating the wear of the rotating shaft.

[0064] The lifting unit 8 is connected to the lower end of the platform adjustment unit 7 and is used to control the up and down movement of the drilling platform 6. The lifting unit 8 adopts an existing square tube electric lifting rod;

[0065] The locking unit 9 is connected to the lower end of the lifting unit 8 and is used to fix the lower end of the lifting unit 8 to the climbing rod 100 of the template climbing device. The locking unit 9 is a locking column fixedly welded to the lower end of the lifting unit 8. When in use, the locking column is inserted into the opening at the upper end of the climbing rod 100 and tightened by the screws threaded on the climbing rod 100.

[0066] like Figure 6 As shown, the lateral movement unit 2 includes two sets of support seats 22 correspondingly arranged on the upper end of the drilling platform 6, and a lateral screw rod 23 is rotatably connected between the two support seats 22, and one end of the lateral screw rod 23 is connected to a lateral drive assembly;

[0067] A matching transverse nut 24 is provided on the transverse screw rod 23 , and the longitudinal moving unit 3 is connected to the transverse nut 24 .

[0068] The transverse drive assembly includes a first motor arranged in the middle of the drilling platform 6. The output end of the first motor is connected to a driving sprocket 26 arranged side by side. The same end of the two transverse screw rods 23 is connected to a driven sprocket 21. The two driving sprockets 26 are respectively connected to the driven sprocket 21 through chains.

[0069] A stabilizing frame 25 is provided at the outer end of the first motor output end. The stabilizing frame 25 is used to provide rotational support for the outer end of the first motor output end to prevent the first motor output end from being subjected to radial force. The stabilizing frame 25 is installed on the drilling platform 6 and is arranged corresponding to the position of the first motor.

[0070] like Figure 3 As shown, the longitudinal moving unit 3 includes a longitudinal rod 31, a first sliding sleeve 33 and a second sliding sleeve 35. The first sliding sleeve 33 and the second sliding sleeve 35 are slidably connected to the longitudinal rod 31. The upper end of the first sliding sleeve 33 is connected to the water drill 4. The second sliding sleeve 35 is provided with a second motor 36. The upper end of the longitudinal rod 31 is fixedly connected to the longitudinal rack 32. A driving gear that cooperates with the longitudinal rack 32 is provided in the first sliding sleeve 33. The driving gear is coaxially connected to a driven pulley. The output end of the second motor 36 is connected to a driving pulley. The driving pulley is connected to the driven pulley through a transmission belt. The belt drive design avoids overload damage to the grinding part 41 at the front end of the drill bit.

[0071] A support rod 34 is connected between the first sliding sleeve 33 and the second sliding sleeve 35. The support rod 34 is adjustably connected to the first sliding sleeve 33 or the second sliding sleeve 35 for adjusting the distance between the first sliding sleeve 33 and the second sliding sleeve 35.

[0072] Both ends of the longitudinal rod 31 are movably connected to the transverse screw rod 23 through transverse nuts 24 .

[0073] The upper end of the drilling platform 6 located below the two transverse screw rods 23 is connected to a heavy-duty slide rail 27, and the lower end of the longitudinal rod 31 is connected to a heavy-duty slider 28 adapted to the heavy-duty slide rail 27, which greatly enhances the stability of the longitudinal rod 31, thereby making the water drill 4 run more smoothly during the drilling process.

[0074] The drilling platform 6 is a square frame composed of channel steels, with the channel steel openings arranged downwards, and both sides are made of a whole longitudinal channel steel 61, and a number of transverse channel steels 62 are connected between the longitudinal channel steels 61;

[0075] The detection unit 5 includes a horizontal detection component 51 arranged at the upper end of the channel steel. The horizontal detection component 51 is a horizontal sensor installed at the upper end of the channel steel. Distance detection components 52 are respectively provided in the notches at the front ends of the two channel steels. The distance detection components 52 are self-resetting displacement sensors.

[0076] The detection unit 5 includes several position detection components 53 arranged on one side of the transverse channel steel 62. The positions of the several position detection components 53 can be adjusted by moving laterally along the transverse channel steel 62. The position detection component 53 is a through-type position sensor, which is fixed in the slide groove of the L frame at one end of the transverse channel steel 62 by screws. Two or three holes need to be drilled at a horizontal distance at the same time. By setting the position of the position detection component 53 in advance and simplifying the control mechanism of the first motor, point-to-point control can be achieved through the position detection component 53.

[0077] like Figure 5 The positioning unit 1 includes a positioning frame 11 arranged at the front end of the drill bit at the output end of the water drill drilling machine 4, and a positioning sleeve 14 is provided on the positioning frame 11. A wear-resistant sleeve 13 is rotatably connected to the interior of the positioning sleeve 14, and a water outlet ring 15 is fixedly connected to one end of the wear-resistant sleeve 13;

[0078] The wear-resistant sleeve 13 is provided with a bell mouth 131 at one end of the water outlet ring 15, and a spiral groove 132 is opened on the inner surface of the wear-resistant sleeve 13, which extends to the bell mouth 131. A water outlet portion 151 is raised on the inner surface of the water outlet ring 15, and a water outlet 152 on the water outlet portion 151 is opened on one side facing the bell mouth 131.

[0079] The water cavity inside the water outlet ring 15 is connected to the original water spray pipe of the water drill drilling machine for use.

[0080] The wear-resistant sleeve 13 adopts a high-chromium alloy embedded rolling bearing structure, and water is sprayed through the water outlet 152 of the water outlet ring 15, so that the spiral groove on the inner wall of the wear-resistant sleeve 13 cooperates with the drill bit during rotation to form a ring cooling and lubrication system. The water flow avoids the heating of the drill bit. At the same time, the drill bit drives the internal water flow to move along the spiral groove during rotation, thereby greatly reducing the wear of the wear-resistant sleeve 13. At the same time, the rotation of the wear-resistant sleeve 13 avoids direct wear when the drill bit touches the wear-resistant sleeve 13, and offsets part of the wear through the rotation of the wear-resistant sleeve 13.

[0081] The outer ring of the wear-resistant sleeve 13 is connected to the inner ring of the positioning sleeve 14 through a plurality of rolling bearings 12. The arrangement of the rolling bearings 12 makes the rotation of the wear-resistant sleeve 13 more flexible.

[0082] like Figure 5 As shown, the inner hole diameter of the wear-resistant sleeve 13 at the end away from the bell mouth 131 is within 5 mm larger than the outer ring diameter of the grinding part 41 at the front end of the drill bit. If the inner hole diameter of the wear-resistant sleeve 13 at the end away from the bell mouth 131 is smaller than the outer ring diameter of the grinding part 41 at the front end of the drill bit, the drill bit cannot pass through the wear-resistant sleeve 13; if the inner hole diameter of the wear-resistant sleeve 13 at the end away from the bell mouth 131 is greater than the outer ring diameter of the grinding part 41 at the front end of the drill bit by more than 5 mm, the water flow in the wear-resistant sleeve 13 cannot play a role in lubrication and support, and the wear-resistant sleeve 13 cannot effectively support the drill bit.

[0083] Working principle:

[0084] Stable attachment and lifting principle:

[0085] like Figure 10 or Figure 11 As shown, the device is rigidly connected to the existing climbing rods 100 of the formwork climbing system via a locking unit 9 at the bottom, tightened by screws, firmly attaching itself to the pier structure. A lifting unit 8 (e.g., an electric lifting rod) uses the climbing rods as vertical guides to drive the entire device up and down along the outer wall of the pier, achieving positioning at the drilling height, typically a fixed height. The climbing rod support bases 200 on the climbing rods 100 are fixed in position, requiring only one set of holes to be drilled and installed, allowing the climbing rods 100 to be raised and secured.

[0086] Principle of precise posture adjustment:

[0087] To ensure verticality during drilling, the device is more than simply fixed to the climbing pole. The level and distance sensors in the detection unit 5 monitor the levelness of the drilling platform 6 and its distance from the pier surface in real time or periodically. Based on this feedback, the operator fine-tunes the horizontal and vertical adjustment cylinders 76 and 74 in the platform adjustment unit 7. By varying the angles of the connecting mechanisms, these cylinders precisely adjust the pitch and roll of the entire drilling platform 6, ensuring the platform is level and ultimately ensuring that the output axis of the water drill rig 4 is strictly perpendicular to the pier surface.

[0088] Principle of precise positioning of drilling position:

[0089] After the drilling platform 6 posture adjustment is completed.

[0090] Transverse Positioning: The first motor drives the active sprocket 26, which, through the chain, synchronously rotates the two transverse screws 23. The transverse nut 24, which engages the transverse screws 23, moves in the same direction (i.e., transversely) as the screws, thereby driving the entire longitudinal movement unit 3 supported on it to achieve horizontal translation.

[0091] Drill bit stability and cooling lubrication principle:

[0092] To mitigate vibration and deflection of the drill bit during drilling, the positioning unit 1 provides a stable support point at the front end of the drill bit. The drill bit passes through a rotatable wear-resistant sleeve 13, which is connected to a fixed bracket via a rolling bearing 12, significantly reducing friction. Simultaneously, a water outlet ring 15 sprays water through a water outlet 152 toward the bell mouth 131. The water flows into the spiral grooves 132 on the inner wall of the wear-resistant sleeve, forming a cooling and lubricating water film as the drill bit rotates. This effectively cools the drill bit and further stabilizes the drill bit through the hydraulic support provided by the water flow, ensuring the accuracy and quality of the drilled hole and extending the life of the drill bit.

[0093] Working process:

[0094] 1. Installation and fixing:

[0095] The auxiliary device as a whole or the lifting unit 8 is disassembled and hoisted onto the climbing formwork operating platform.

[0096] The operator aligns and inserts the locking unit 9 at the bottom of the device into the top opening of the climbing rod 100 of the template climbing device.

[0097] Tighten the compression screw on the climbing pole 100 to firmly lock the auxiliary device on the climbing pole 100 .

[0098] 2. Vertical coarse positioning:

[0099] The lifting unit 8 (electric lifting rod) is started to control the entire device to vertically rise or fall along the climbing rod 100.

[0100] Move the device to the location where the hole needs to be drilled, and then stop lifting.

[0101] 3. Platform posture fine-tuning:

[0102] The operator views the real-time data fed back by the detection unit 5 (level sensor, distance sensor) on the control system interface.

[0103] The vertical adjustment electric cylinder 74 and the horizontal adjustment electric cylinder 76 of the platform adjustment unit 7 are respectively started by remote control or short-range operation.

[0104] Fine-tune the electric cylinder until the data shows that the drilling platform 6 is completely horizontal and maintains a preset vertical relationship with the outer wall of the pier.

[0105] 4. Accurate positioning of drilling points:

[0106] The first motor of the horizontal moving unit 2 is activated to drive the longitudinal moving unit 3 to move left and right as a whole, aligning it with the horizontal coordinates of the target. The position detection component 53 can be pre-set to achieve one-button point-to-point rapid positioning.

[0107] 5. Perform drilling:

[0108] After confirming that the positioning is correct, the second motor 36 of the longitudinal moving unit 3 is started to drive the grinding portion 41 at the front end of the drill bit of the water drill 4 to pass through the wear-resistant sleeve 13 .

[0109] The water supply system of the water drill 4 is started, and the water outlet ring 15 starts to spray water for cooling.

[0110] Start the water drill spindle rotation.

[0111] The water drill's feed mechanism (driven by the second motor 36 of the longitudinal movement unit 3) is controlled to slowly and evenly advance the drill bit into the concrete surface of the pier until it reaches the desired depth. The positioning unit 1 provides continuous support and cooling throughout the entire process.

[0112] 6. Completion and Reset:

[0113] When drilling is complete, withdraw the drill bit from the hole.

[0114] Turn off the water drill and water supply.

[0115] To drill the next hole at the same height, repeat steps 4 and 5.

[0116] If all operations at the current height are completed, the device is moved to a new climbing pole 100; or the device is lowered and dismantled.

[0117] The description of the direction and relative position relationship of the structure in the present invention, such as the description of front, back, left, right, up and down, does not constitute a limitation of the present invention and is only for the convenience of description.
