Description

Technical Field

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

[0002] The formwork climbing system (abbreviation: "climbing formwork") is a key device in the construction of high-rise concrete structures (such as piers and core tubes). It integrates formwork, support, and climbing functions, and can climb upward section by section along the already poured concrete structure, greatly improving the construction efficiency. A typical climbing formwork system usually includes formwork, climbing mechanisms (such as climbing rails or climbing rods), support trusses, and multiple layers of operating platforms, etc.

[0003] The climbing action of the climbing formwork system depends on its reliable connection with the already formed concrete structure. In standard construction, climbing rails or attachment members for connection and guidance are usually pre-embedded when pouring the upper section of concrete, which is the most conventional and efficient method.

[0004] However, in specific engineering scenarios, the pre-embedding method is not feasible, and the "post-anchoring" technology must be adopted, that is, drilling holes on the surface of the hardened concrete to implant anchor bolts to fix the climbing rails or attachments. These typical scenarios include: Reinforcement and renovation of old piers: When carrying out construction of increasing the height or cross-section of existing piers, there are no pre-embedded parts in the original structure, and the climbing formwork system can only be attached by the post-anchoring method.

[0005] Remedy for construction mistakes: In conventional construction, if pre-embedded parts are missed or their positions deviate, the post-anchoring drilling method must also be used for remedy.

[0006] In the above scenarios where post-anchoring drilling must be adopted, the inventor found that the existing drilling operation methods have serious technical defects: The existing drilling methods usually use a water drill drilling machine held manually or fixed with a simple support for operation. When the drilling position is relatively high and beyond the standing range of the operator, the common practice is to temporarily set up a scaffold or a climbing ladder on the multiple layers of operating platforms carried by the climbing formwork. This seemingly simple "adding height on height" operation method brings fatal safety hazards and efficiency bottlenecks: Extremely high safety risks: The climbing formwork operating platform itself is already a high-altitude operation environment, with limited space and load-bearing capacity. Setting up an unstable scaffold on the platform makes the center of gravity of the operator higher and the activity space narrower. When operating with a vibrating water drill drilling machine held by hand, it is extremely easy to cause high-altitude falling accidents due to instability, scaffold shaking, or misoperation, and the risk coefficient increases exponentially.

[0007] Low work efficiency and difficult to guarantee accuracy: Manually supporting the drilling machine on the high-altitude and unstable scaffolding not only has a high labor intensity, but also it is difficult to guarantee the accuracy of the drilling angle and depth. Repeated positioning and calibration consume a lot of time, directly affecting the overall progress of the climbing formwork construction. Summary of the Invention

[0008] The technical problem to be solved by the present invention is: To overcome the deficiencies of the prior art, provide an auxiliary device for climbing the pier formwork, avoid dangerous construction by operators, and accurately position the drilling position.

[0009] The auxiliary device for climbing the pier formwork described in the present invention includes: A drilling platform, on which a lateral moving unit, a longitudinal moving unit, a water drill, a positioning unit and a detection unit are respectively provided. The lateral moving unit and the longitudinal moving unit are respectively used to drive the movement of the water drill. The positioning unit is used to ensure the stability of the drill bit at the output end of the water drill. The detection unit is used to ensure the levelness of the drilling platform and the perpendicularity of the drill bit at the output end of the water drill relative to the outer wall of the pier; A platform adjustment unit, connected to the lower end of the drilling platform, and cooperating with the detection unit to adjust the levelness of the drilling platform and the perpendicularity of the drill bit at the output end of the water drill relative to the outer wall of the pier; A lifting unit, connected to the lower end of the platform adjustment unit, and used to control the up and down movement of the drilling platform; A locking unit, connected to the lower end of the lifting unit, and used to fixedly connect the lower end of the lifting unit to the climbing rod of the formwork climbing device.

[0010] The lateral moving unit includes two groups of support seats correspondingly arranged at the upper end of the drilling platform. A lateral lead screw is rotatably connected between the two support seats. One end of the lateral lead screw is connected with a lateral driving assembly; A lateral nut adapted to the lateral lead screw is provided on the lateral lead screw, and a longitudinal moving unit is connected to the lateral nut.

[0011] The lateral driving assembly includes a first motor arranged in the middle of the drilling platform. The output end of the first motor is connected with a pair of active sprockets arranged side by side. Both ends of the two lateral lead screws are respectively connected with driven sprockets. The two active sprockets are respectively connected to the driven sprockets through chains.

[0012] 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 to the longitudinal rod. The upper end of the first sliding sleeve is connected with a water drill. A second motor is provided on the second sliding sleeve. The upper end of the longitudinal rod is fixedly connected with a longitudinal rack. A driving gear cooperating with the longitudinal rack is arranged in the first sliding sleeve. The driving gear is coaxially connected with a driven pulley. The output end of the second motor is connected with an active pulley. The active pulley is connected to the driven pulley through a transmission belt; A support rod is connected between the first sliding sleeve and the second sliding sleeve. 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. Both ends of the longitudinal rod are movably connected to the transverse lead screw through transverse nuts.

[0013] At the upper end of the drilling platform located below the two transverse lead screws, a heavy-duty slide rail is connected. At the lower end of the longitudinal rod, a heavy-duty slider adapted to the heavy-duty slide rail is connected.

[0014] The drilling platform is a square frame composed of channel steels. The channel steels are arranged with the openings facing downwards. The two sides are respectively made of whole longitudinal channel steels, and a number of transverse channel steels are connected between the longitudinal channel steels. The detection unit includes a horizontal detection component arranged at the upper end of the channel steel, and distance detection components are respectively arranged in the notches at the front ends of the two channel steels.

[0015] The detection unit includes a number of position detection components arranged on one side of the transverse channel steel, and the positions of the number of position detection components can be adjusted horizontally along the transverse channel steel.

[0016] The positioning unit includes a positioning frame arranged at the front end of the drill bit at the output end of the water drill drilling machine. A positioning sleeve is provided on the positioning frame. A wear-resistant sleeve is rotatably connected inside the positioning sleeve. One end of the wear-resistant sleeve is fixedly connected with a water outlet ring. One end of the wear-resistant sleeve located at the water outlet ring is provided with a flared opening. A spiral groove is formed on the inner surface of the wear-resistant sleeve, and the spiral groove extends to the flared opening. A water outlet part protrudes on the inner surface of the water outlet ring, and a water outlet on the water outlet part is arranged facing one side of the flared opening.

[0017] The outer ring of the wear-resistant sleeve is connected to the inner ring of the positioning sleeve through a number of rolling bearings.

[0018] The inner hole diameter of the end of the wear-resistant sleeve far from the flared opening is 5 mm or less larger than the outer ring diameter of the grinding part at the front end of the drill bit.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention transforms the high-risk manual high-altitude drilling operation into remote control or short-range operation of a mechanical device on the main platform of the climbing formwork. Workers no longer need to build unstable scaffolding or climbing ladders, completely eliminating the risk of high-altitude falls caused by the "high-on-high" operation method, and making a qualitative leap in construction safety.

[0020] The present invention makes the positioning of the drill bit more accurate through the cooperation of the detection unit and the platform adjustment unit, ensuring the position of the drilled hole. Description of the Drawings

[0022] Embodiment As Figures 1 to 11 shown, the climbing assistance device for pier formwork of the present invention includes: Drilling platform 6, on which a lateral moving unit 2, a longitudinal moving unit 3, a water drill 4, a positioning unit 1 and a detection unit 5 are respectively provided. The lateral moving unit 2 and the longitudinal moving 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, and the detection unit 5 is used to ensure the levelness of the drilling platform 6 and the perpendicularity of the drill bit at the output end of the water drill 4 relative to the outer wall of the pier; Platform adjustment unit 7, connected to the lower end of the drilling platform 6, and cooperating with the detection unit 5 to adjust the levelness of the drilling platform 6 and the perpendicularity of the drill bit at the output end of the water drill 4 relative to the outer wall of the pier; The platform adjustment unit 7 includes an adjustment frame 73. One end of the adjustment frame 73 is rotatably connected to a rotating shaft 71. A rotating plate 72 is key-connected to the rotating shaft 71. The adjustment frame 73 is hinged to a vertical adjustment electric cylinder 74. The output end of the vertical adjustment electric cylinder 74 is hinged to the rotating plate 72. By the action of the vertical adjustment electric cylinder 74, the rotation of the rotating shaft 71 can be controlled. A support plate 64 is welded to the lower end of the drilling platform 6 (as Figure 7 shown), and a rotating sleeve 63 is fixed on the support plate 64. The rotating sleeve 63 is key-connected to the rotating shaft 71.

[0023] As Figure 8 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. A horizontal adjustment plate 77 is bolted below the connecting seat 78 and located between the hinge plate 75. A horizontal adjustment electric cylinder 76 is hinged between the horizontal adjustment plate 77 and the adjustment frame 73. By the action of the horizontal adjustment electric cylinder 76, the rotation of the adjustment frame 73 along the hinge point between the hinge plate 75 and the adjustment frame 73 can be controlled, realizing the movement of the adjustment frame 73, and thus driving the drilling platform 6 to perform horizontal adjustment.

[0024] As Figure 9 shown, one end of the adjustment frame 73 away from the rotating shaft 71 is connected with a bull's eye bearing 731. The adjustment frame 73 realizes the strengthening support for the support plate 64 through the bull's eye bearing 731, avoiding the gravity of the drilling platform 6 acting entirely on the rotating shaft 71, thereby accelerating the wear at the rotating shaft.

[0025] The lifting unit 8, connected to the lower end of the platform adjustment unit 7, is used to control the up and down movement of the drilling platform 6. The lifting unit 8 adopts an existing electric lifting rod with a square cylinder. The locking unit 9, connected to the lower end of the lifting unit 8, is used to fixedly connect the lower end of the lifting unit 8 to the climbing rod 100 of the formwork climbing device. The locking unit 9 is a locking column fixedly welded to the lower end of the lifting unit 8. During use, the locking column is inserted into the opening at the upper end of the climbing rod 100 and tightened by a screw threadedly connected to the climbing rod 100.

[0026] As Figure 6 shown, the lateral movement unit 2 includes two groups of support seats 22 correspondingly arranged at the upper end of the drilling platform 6. A lateral lead screw 23 is rotatably connected between the two support seats 22, and one end of the lateral lead screw 23 is connected to a lateral drive assembly. A lateral nut 24 adapted to the lateral lead screw 23 is provided on the lateral lead screw 23, and a longitudinal movement unit 3 is connected to the lateral nut 24.

[0027] The lateral drive assembly includes a first motor provided in the middle of the drilling platform 6. The output end of the first motor is connected to a pair of active sprockets 26 arranged side by side. The same end of the two lateral lead screws 23 is respectively connected to a driven sprocket 21, and the two active sprockets 26 are respectively connected to the driven sprockets 21 through chains.

[0028] A stabilizing frame 25 is provided at the outer end of the output end of the first motor. The stabilizing frame 25 is used to rotationally support the outer end of the output end of the first motor to avoid the output end of the first motor from bearing radial forces. The stabilizing frame 25 is installed on the drilling platform 6 and is arranged corresponding to the position of the first motor.

[0029] As Figure 3 shown, the longitudinal movement 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 a water drill 4. A second motor 36 is provided on the second sliding sleeve 35. The upper end of the longitudinal rod 31 is fixedly connected to a longitudinal rack 32. A driving gear cooperating 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. Through the design of belt drive, the grinding part 41 at the front end of the drill bit is prevented from being damaged due to overload. 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 and is used to adjust the distance between the first sliding sleeve 33 and the second sliding sleeve 35. Both ends of the longitudinal rod 31 are movably connected to the lateral lead screw 23 through the lateral nut 24.

[0030] At the upper end of the drilling platform 6 below the two horizontal lead screws 23, a heavy-duty slide rail 27 is connected. At the lower end of the longitudinal rod 31, a heavy-duty slider 28 adapted to the heavy-duty slide rail 27 is connected, greatly enhancing the stability of the longitudinal rod 31, so that the water drill drilling machine 4 runs more smoothly during the drilling process.

[0031] The drilling platform 6 is a square frame composed of channel steels. The channel steels are arranged with the openings facing downwards. The two sides are respectively made of the whole longitudinal channel steels 61, and a number of transverse channel steels 62 are connected between the longitudinal channel steels 61; 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 arranged in the notches at the front ends of the two channel steels. The distance detection component 52 is a self-resetting displacement sensor.

[0032] The detection unit 5 includes a number of position detection components 53 arranged on one side of the transverse channel steel 62. The positions of the number of position detection components 53 can be adjusted horizontally along the transverse channel steel 62. The position detection component 53 is a transmissive position sensor, which is fixed in the chute of the L-shaped frame at one end of the transverse channel steel 62 by screws. When it is necessary to drill two or three holes horizontally at the same time, by presetting the positions of the position detection components 53, the control mechanism of the first motor can be simplified, and point-to-point control can be realized through the position detection components 53.

[0033] As Figure 5 described, 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. A positioning sleeve 14 is provided on the positioning frame 11. A wear-resistant sleeve 13 is rotatably connected inside the positioning sleeve 14. One end of the wear-resistant sleeve 13 is fixedly connected with a water outlet ring 15; One end of the wear-resistant sleeve 13 where the water outlet ring 15 is located is provided with a flared opening 131. A spiral groove 132 is opened on the inner surface of the wear-resistant sleeve 13, and the spiral groove 132 extends to the flared opening 131. A water outlet portion 151 protrudes 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 flared opening 131.

[0034] The water cavity inside the water outlet ring 15 is connected and used with the original water spray pipe of the water drill drilling machine.

[0035] The wear-resistant sleeve 13 adopts a high-chromium alloy embedded rolling bearing structure. Water is sprayed through the water outlet 152 of the water outlet ring 15, so that a ring cooling and lubrication system is formed by the cooperation of the inner wall of the wear-resistant sleeve 13 with the spiral groove during the rotation of the drill bit. The heat of the drill bit is avoided through the water flow. At the same time, the internal water flow is driven to move along the spiral groove during the rotation of the drill bit, thus 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 a part of the wear is offset through the rotation of the wear-resistant sleeve 13.

[0036] The outer ring of the wear-resistant sleeve 13 is connected to the inner ring of the positioning sleeve 14 through a number of rolling bearings 12. Through the setting of the rolling bearings 12, the rotation of the wear-resistant sleeve 13 is made more flexible.

[0037] As Figure 5 shown, the inner hole diameter at the end of the wear-resistant sleeve 13 away from the bell mouth 131 is greater than the outer ring diameter of the front grinding part 41 of the drill bit by within 5 mm. If the inner hole diameter at the end of the wear-resistant sleeve 13 away from the bell mouth 131 is less than the outer ring diameter of the front grinding part 41 of the drill bit, the drill bit cannot pass through the wear-resistant sleeve 13; if the inner hole diameter at the end of the wear-resistant sleeve 13 away from the bell mouth 131 is greater than the outer ring diameter of the front grinding part 41 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 at the same time, the wear-resistant sleeve 13 cannot effectively support the drill bit well.

[0038] Working principle: Principle of stable attachment and lifting: As Figure 10 or Figure 11 shown, the device is rigidly connected to the existing climbing rod 100 of the formwork climbing system through the locking unit 9 at the bottom by means of screw pressing, and is stably attached to the pier structure. The lifting unit 8 (such as an electric lifting rod) uses the climbing rod as a vertical guide rail to drive the entire device to move up and down along the outer wall of the pier to achieve the positioning of the drilling operation height, usually a fixed height. The position of the climbing rod support seat 200 on the climbing rod 100 is fixed, and usually only one set of holes needs to be drilled. Installing one set of climbing rod support seats 200 can lift the climbing rod 100 up for fixation.

[0039] Principle of precise attitude adjustment: To ensure the perpendicularity of the drilling, the device is not simply fixed on the climbing rod. The horizontal sensor and distance sensor in the detection unit 5 will monitor the level of the drilling platform 6 itself and its distance from the pier surface in real time or at regular intervals. According to these feedback data, the operator makes fine adjustments through the horizontal adjustment electric cylinder 76 and the vertical adjustment electric cylinder 74 in the platform adjustment unit 7. By changing the angle of the connecting mechanism, these two electric cylinders can precisely adjust the pitch and roll of the entire drilling platform 6 to ensure the platform is level and ultimately ensure that the output axis of the diamond drill 4 is strictly perpendicular to the pier surface.

[0040] Principle of precise positioning of drilling position: After the attitude of the drilling platform 6 is adjusted.

[0041] Lateral positioning: The first motor drives the driving sprocket 26, and synchronously drives the two lateral lead screws 23 to rotate through the chain. The lateral nuts 24 cooperating with the lateral lead screws 23 will move along the lead screw direction (i.e., laterally), thereby driving the entire longitudinal moving unit 3 carried thereon to achieve horizontal translation.

[0042] Principle of Drill Bit Stabilization and Cooling Lubrication: To overcome the vibration and deviation 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 the rotatable wear-resistant sleeve 13, which is connected to the fixed bracket through the rolling bearing 12, greatly reducing the friction. At the same time, the water outlet ring 15 sprays water to the flared mouth 131 through the water outlet 152, and the water flow enters the spiral groove 132 on the inner wall of the wear-resistant sleeve. When the drill bit rotates, a cooling and lubricating water film is formed. This can not only effectively cool the drill bit but also further stabilize the drill bit by using the hydraulic support of the water flow, ensuring the accuracy and quality of drilling and prolonging the service life of the drill bit.

[0043] Working Process: 1. Installation and Fixation: Lift and install the entire auxiliary device or disassemble and lift the lifting unit 8 to the climbing formwork operation platform.

[0044] The operator aligns the locking unit 9 at the bottom of the device and inserts it into the top opening of the climbing rod 100 of the formwork climbing device.

[0045] Tighten the compression screw on the climbing rod 100 to firmly lock the auxiliary device on the climbing rod 100.

[0046] 2. Vertical Coarse Positioning: Start the lifting unit 8 (electric lifting rod) to control the entire device to rise or fall vertically along the climbing rod 100.

[0047] Move the device to the position where drilling is required, and then stop lifting.

[0048] 3. Fine Adjustment of Platform Attitude: The operator checks the real-time data fed back by the detection unit 5 (horizontal sensor, distance sensor) on the control system interface.

[0049] Start the vertical adjustment cylinder 74 and the horizontal adjustment cylinder 76 of the platform adjustment unit 7 respectively through remote control or short-range operation.

[0050] Fine-tune the 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 bridge pier.

[0051] 4. Precise Positioning of Drilling Point: Start the first motor of the lateral movement unit 2 to drive the entire longitudinal movement unit 3 to move left and right to align it with the target horizontal coordinates. The position detection component 53 can be preset to achieve one-key point-to-point rapid positioning.

[0052] 5. Execute Drilling: After confirming that the positioning is correct, start the second motor 36 of the longitudinal movement unit 3 to drive the grinding part 41 at the front end of the drill bit of the diamond drill 4 through the wear-resistant sleeve 13.

[0053] Start the water supply system of the diamond drill 4, and the water outlet ring 15 starts to spray water for cooling.

[0054] Start the rotation of the main shaft of the diamond drill.

[0055] Control the feed mechanism of the diamond drill (driven by the second motor 36 of the longitudinal movement unit 3) to make the drill bit slowly and evenly drill into the concrete surface of the pier until the predetermined depth is reached. The positioning unit 1 continuously provides stable support and cooling throughout the process.

[0056] 6. Completion and reset: After drilling is completed, withdraw the drill bit from the hole.

[0057] Turn off the diamond drill and the water supply system.

[0058] If it is necessary to drill the next hole at the same height, repeat steps 4 and 5.

[0059] If all the operations at the current height are completed, move the device to a new climbing rod 100; or lower and remove the device.

[0060] In the present invention, the description of the direction and relative position relationship of the structure, such as the description of front, back, left, right, up and down, does not constitute a limitation to the present invention, but is only for the convenience of description.
