Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and specifically to an intelligent climbing device for the slip form construction of bridge piers. Background Art

[0002] Slip form construction is a construction method for pouring vertical concrete structures by using a hydraulic lifting device to lift the formwork. According to the plane shape of the building, a complete set of hydraulic slip form devices is assembled on the ground. The hydraulic jacks climb on the support rods, driving the lifting frame, formwork, and operation platform to rise together. After pouring each layer of concrete, the formwork is lifted until the structure pouring is completed. During this construction method, the formwork system needs to be frequently leveled to ensure the verticality of the building and structure. Traditional slip form construction equipment usually uses single-motor drive or manual adjustment for formwork climbing, and there are the following technical bottlenecks: The single-rope lifting method driven by a single motor is extremely likely to cause uneven force on the formwork during construction, resulting in skewing. The verticality deviation of the piers constructed by this method averages ±15 mm, and the surface flatness deviation exceeds ±5 mm, seriously affecting the overall quality and aesthetics of the bridge structure. At the same time, due to the lack of effective real-time monitoring means, construction workers can only rely on manual inspections of equipment pressure and formwork displacement. Not only is the monitoring efficiency low, but also the construction process cannot be dynamically adjusted. Once an abnormal situation occurs, it is difficult to respond and handle in a timely manner, and the safety risk is extremely high. There are often concrete pouring quality accidents and equipment failure problems caused by formwork inclination. Moreover, in the existing technology, although some improved climbing equipment introduces multi-motor collaborative drive, it lacks the integrated design of double-rope tension balance, dynamic guiding constraint, and intelligent monitoring system, and it is difficult to meet the requirements of modern bridge engineering for high piers and high-precision construction. Therefore, the technical personnel in this field provide an intelligent climbing device for the slip form construction of bridge piers to solve the problems raised in the above background art. Summary of the Invention

[0003] The purpose of the present invention is to provide an intelligent climbing device for the slip form construction of bridge piers to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions: An intelligent climbing device for the slip form construction of bridge piers, comprising a climbing frame, a formwork, a guide column, a mounting plate, a lifting cylinder, an adjusting mechanism and a construction ground.

A guide protrusion adapted to the guide groove is arranged at the end of the piston rod of the lifting cylinder. The guide protrusion is embedded in the guide groove. Through the cooperation of the guide groove and the guide protrusion.

[0009] As a further scheme of the present invention: Scale marks are arranged along the length direction on the guide frame. An indicating mark adapted to the scale marks is arranged on the guide block.

[0010] As a further aspect of the present invention: A sensor assembly is provided on the mounting plate. The sensor assembly includes a pressure sensor and a displacement sensor. The pressure sensor is used to detect the working pressure of the lifting cylinder, and the displacement sensor is used to monitor the climbing height of the formwork. The sensor assembly is electrically connected to an external control system.

[0011] As a further aspect of the present invention: A central ring is provided at the center of the construction ground. Reinforcing ribs are provided on one side of the central ring close to the climbing frame. One end of each reinforcing rib is fixedly connected to the climbing frame.

[0012] As a further aspect of the present invention: Guide rollers are provided on one side of the fixing frame close to the formwork. The guide rollers cooperate with the surface of the formwork, and a concrete pier is poured between the formworks.

[0013] As a further aspect of the present invention: The surface of the guide roller is provided with a wear-resistant rubber layer. The Shore hardness of the wear-resistant rubber layer is 60-70HA. The guide roller is rotatably connected to the fixing frame through a bearing. The formwork adopts a combined steel formwork, and the combined steel formwork includes a panel, stiffening ribs and a support frame. The thickness of the panel is 6mm.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. During the slip form construction of bridge piers, first arrange the climbing frames annularly on the construction ground. The central ring and the reinforcing ribs provide stable basic support for the entire equipment, ensuring the overall stability of the equipment during construction. After the lifting cylinder is started, the piston rod extends, and the guiding protrusion at the end moves along the spiral guiding groove on the outer peripheral surface of the guiding column. Due to the cooperation between the guiding groove and the guiding protrusion, the rotation of the guiding column is restricted, so that the guiding column can only move up and down stably along the axis, providing power support for the climbing of the formwork, and the adjusting mechanism is responsible for the precise control of the formwork; 2. In terms of construction monitoring, the sensor assembly on the mounting plate plays a key role. The pressure sensor continuously detects the working pressure of the lifting cylinder. If the pressure is abnormal and exceeds the preset threshold, it may mean that the equipment is stuck or overloaded. The displacement sensor continuously monitors the climbing height of the formwork, and transmits the pressure and displacement data to the external control system in real time. The external control system analyzes and judges based on these data, automatically adjusts the telescopic speed of the lifting cylinder and the operation of the drive motor in the adjusting mechanism, ensures that the formwork rises at an appropriate speed and state, and at the same time issues an alarm in time when an abnormality occurs, reminding the construction personnel to check and handle. As the formwork continues to rise, concrete is poured inside the formwork, and the newly poured concrete takes shape under the restraint of the formwork. When the formwork rises to a certain height, repeat the above operations, continuously carry out concrete pouring and formwork climbing until the slip form construction of the entire bridge pier is completed; 3. After the first driving motor starts, the power is transmitted to the first driving wheel through the rotating shaft. The meshing of the first driving wheel and the first transmission wheel transfers the rotational motion to the first winding roller. As the first winding roller rotates, the pulling rope is wound up, directly pulling the formwork to rise along the guide frame. The second driving motor of the auxiliary stabilization system works synchronously, driving the second driving wheel to drive the second transmission wheel, causing the second winding roller to rotate. The auxiliary rope is connected to the formwork through a connector. While the pulling rope lifts the formwork, the auxiliary rope provides a balancing pulling force to prevent the formwork from tilting due to uneven stress. The first driving motor and the second driving motor are independently powered and work together. If one of the motors fails, the other motor can maintain the stability of the formwork for a short time to prevent the formwork from falling or tilting. The slight adjustment of the two motors can vertically adjust the position of the formwork to meet the requirements of high-standard projects for the accuracy of pier columns and reduce the shaping error of slip form construction.

[0015] 4. The guide rollers on the fixing frame are in rolling contact with the surface of the formwork, forming a rolling friction pair. When the formwork rises, the guide rollers not only limit the horizontal displacement of the formwork but also reduce the sliding resistance, ensuring that the formwork climbs precisely along the predetermined trajectory. During the concrete pouring process of the concrete forming assistance, the guide rollers also play a supporting role for the formwork, offsetting the deformation caused by the lateral pressure of the concrete.

[0016] 5. The central ring is located at the center of the construction ground and is tightly connected to the surrounding annularly arranged climbing frames through reinforcing ribs, jointly constituting a stable foundation support structure. During the construction process, the equipment will bear various loads generated from the formwork, concrete, and its own operation. With its own structural strength and the connection design with the reinforcing ribs and climbing frames, the central ring can evenly disperse these loads to the construction ground, effectively preventing the equipment from tilting due to uneven stress. When pouring concrete, the lateral pressure of the concrete will be transmitted to the climbing frame through the formwork. The central ring and the reinforcing ribs work together to disperse this part of the pressure, ensuring the overall stability of the entire equipment system during the construction process and providing a reliable foundation guarantee for a series of construction operations such as subsequent formwork climbing and concrete pouring.

[0017] 6. Guide frames are symmetrically arranged on both sides of the climbing frame. Each group of guide frames corresponds to a guide block of a formwork. By comparing the scale values of the indicating marks on the guide frames on both sides, it is possible to quickly determine whether the formwork is tilted or horizontally displaced. If the height of the indicating mark on the left side is lower than that on the right side, it means that the right side of the formwork is higher, and the pulling rope and the auxiliary rope need to be adjusted by the adjusting mechanism motor to correct the deviation, thereby controlling the construction deviation.

[0018] 7. During the climbing process of the formwork, the guide roller and the formwork surface are in continuous contact and roll relative to each other. The wear-resistant rubber layer has good wear resistance, which can effectively reduce the friction loss between the two, avoid scratches and deformation on the formwork surface due to long-term friction, extend the service life of the formwork, and reduce the frequency and cost of formwork replacement. The formwork is composed of panels, stiffening ribs and support frames. This modular design allows the formwork to be disassembled into smaller parts during transportation, which is convenient for handling and loading and unloading, reducing transportation difficulty and cost. At the construction site, it can also be flexibly assembled according to actual needs, improving installation efficiency and shortening construction preparation time. The panel provides a surface for concrete molding. The thickness of 6mm ensures sufficient rigidity to withstand the lateral pressure during concrete pouring and avoid panel deformation affecting the quality of the concrete surface. The stiffening ribs and support frames are connected to the panel to form a solid frame structure, which significantly enhances the overall strength and stability of the formwork, ensuring that the formwork can maintain the stability of shape and position when subjected to various loads such as concrete pressure and equipment lifting force, and ensure the dimensional accuracy of the bridge piers. At the same time, the modular steel formwork has high durability and can be reused many times under normal use and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

Adjusting mechanisms 6 are arranged on both sides of the climbing frame 1. Guiding frames 12 are symmetrically arranged on both sides of the climbing frame 1. A guiding block 11 is slidably connected to the guiding frame 12. A formwork 2 is arranged on one side of the guiding block 11 away from the guiding frame 12. A pulling rope 10 is arranged on the upper side of the formwork 2. The pulling rope 10 passes through the mounting plate 4 and is connected to the adjusting mechanism 6; In this embodiment, specifically, a spiral guiding groove is arranged on the outer peripheral surface of the guiding column 3, and a guiding protrusion adapted to the guiding groove is arranged at the end of the piston rod of the lifting cylinder 5. The guiding protrusion is embedded in the guiding groove. Through the cooperation of the guiding groove and the guiding protrusion; Scale marks are arranged along the length direction on the guiding frame 12, and an indicating mark cooperating with the scale marks is arranged on the guiding block 11; A sensor assembly is arranged on the mounting plate 4. The sensor assembly includes a pressure sensor and a displacement sensor. The pressure sensor is used to detect the working pressure of the lifting cylinder 5, and the displacement sensor is used to monitor the climbing height of the formwork 2. The sensor assembly is electrically connected to an external control system; A central ring 15 is provided at the center of the construction ground 17. Reinforcing ribs 16 are provided on one side of the central ring 15 close to the climbing frame 1. One end of each reinforcing rib 16 is fixedly connected to the climbing frame 1; A wear-resistant rubber layer is provided on the surface of the guiding roller 9. The Shore hardness of the wear-resistant rubber layer is 60 - 70 HA. And the guiding roller 9 is rotatably connected to the fixing frame 601 through a bearing. The formwork 2 adopts a combined steel formwork. The combined steel formwork includes a panel, stiffening ribs and a support frame. The thickness of the panel is 6 mm; During the construction of the bridge pier column slip formwork, first arrange the climbing frame 1 annularly on the construction ground 17. The central ring 15 and the reinforcing ribs 16 provide stable basic support for the whole equipment, ensuring the overall stability of the equipment during the construction process. After the lifting cylinder 5 is started, the piston rod extends, and the guiding protrusion at the end moves along the spiral guiding groove on the outer peripheral surface of the guiding column 3. Due to the cooperation between the guiding groove and the guiding protrusion, the rotation of the guiding column 3 is restricted, so that the guiding column 3 can only move up and down stably along the axial direction, providing power support for the climbing of the formwork 2. The adjusting mechanism 6 is responsible for the precise control of the formwork 2; In terms of construction monitoring, the sensor assembly on the mounting plate 4 plays a key role. The pressure sensor continuously detects the working pressure of the lifting cylinder 5. If the pressure is abnormal and exceeds the preset threshold, it may mean that the equipment is stuck or overloaded. The displacement sensor continuously monitors the climbing height of the formwork 2, and transmits the pressure and displacement data to the external control system in real time. The external control system analyzes and judges based on these data, automatically adjusts the telescopic speed of the lifting cylinder 5 and the operation of the drive motor in the adjusting mechanism 6, ensuring that the formwork 2 rises at an appropriate speed and state. At the same time, an alarm is issued in time when an abnormality occurs, reminding the construction personnel to check and handle. As the formwork 2 continuously rises, concrete is poured inside the formwork 2. The newly poured concrete is formed under the constraint of the formwork 2. When the formwork 2 rises to a certain height, repeat the above operations, continuously carry out concrete pouring and formwork climbing until the slip formwork construction of the entire bridge pier column is completed; The central ring 15 is located at the center of the construction ground 17 and is closely connected to the climbing frames 1 arranged annularly around through the reinforcing ribs 16, jointly forming a stable basic support structure. During the construction process, the equipment will bear various loads generated by the formwork 2, concrete and its own operation. The central ring 15, relying on its own structural strength and the connection design with the reinforcing ribs 16 and the climbing frames 1, can evenly disperse these loads to the construction ground 17, effectively preventing the equipment from tilting due to uneven force. When pouring concrete, the lateral pressure of the concrete is transmitted to the climbing frame 1 through the formwork 2. The central ring 15 and the reinforcing ribs 16 work together to disperse this part of the pressure, ensuring the overall stability of the entire equipment system during the construction process and providing a reliable basic guarantee for a series of construction operations such as subsequent formwork climbing and concrete pouring; Guide frames 12 are symmetrically arranged on both sides of the climbing frame 1, and each set of guide frames corresponds to a guide block 11 of a template 2. By comparing the scale values ​​of the indicator marks on the guide frames on both sides, it can be quickly determined whether the template is tilted or horizontally displaced. If the indicator mark on the left side shows a lower height than the right side, it means that the right side of the template is too high, and the adjustment mechanism 6 motor needs to be used to control the pull rope 10 and the auxiliary rope 14 to correct the deviation, thereby controlling the construction deviation; During the climbing process of the template 2, the guide roller 9 is in continuous contact with the template surface and rolls relatively. The wear-resistant rubber layer has good wear resistance, which can effectively reduce the friction loss between the two, avoid scratches and deformation on the template surface due to long-term friction, extend the service life of the template, and reduce the frequency and cost of template replacement. The template 2 is composed of components such as panels, stiffening ribs and support frames. This modular design allows the template to be disassembled into smaller components during transportation, which is convenient for handling and loading and unloading, reducing transportation difficulty and cost. At the construction site, it can also be flexibly assembled according to actual needs, improving installation efficiency and shortening construction preparation time. The panel provides a surface for concrete molding. The thickness of 6mm ensures sufficient rigidity and can withstand the lateral pressure during concrete pouring, avoiding panel deformation from affecting the quality of the concrete surface. The stiffening ribs and support frames are connected to the panel to form a solid frame structure, which significantly enhances the overall strength and stability of the template, ensuring that the template can maintain the stability of shape and position when subjected to various loads such as concrete pressure and equipment lifting force, and ensuring the dimensional accuracy of the bridge pier. At the same time, the combined steel template has high durability and can be reused many times under normal use and maintenance. Example

[0029] Reference Figures 2-4 , this embodiment is based on the previous embodiment, and is different from the previous embodiment in that the adjustment mechanism 6 includes a fixed frame 601, a first drive motor 602, a rotating shaft 603, a first driving wheel 604, a first winding roller 605, a first transmission wheel 606, a driving frame 607, a second driving wheel 608 and a second winding roller 609, one side of the climbing frame 1 is fixedly connected to the fixed frame 601, one side of the fixed frame 601 is fixedly connected to the driving frame 607, the driving frame 607 is fixedly connected to the first drive motor 602, the first drive motor 602 is provided with a rotating shaft 603 inside the fixed frame 601, the rotating shaft 603 is fixedly connected to the first driving wheel 604, and the first winding roller 605 is movably connected inside the fixed frame 601, and the first winding roller 605 is fixedly connected to the first transmission wheel 606 on the side close to the first driving wheel 604, and the first transmission wheel 606 and the first driving wheel 604 are meshed with each other; A second driving motor 602 is fixedly connected inside the fixing frame 601. The output end of the second driving motor 610 is fixedly connected with a second driving wheel 608. And a second winding roller 609 is arranged below the first winding roller 605 in the fixing frame 601. The second winding roller 609 is provided with a second transmission wheel 611 through the fixing frame 601. The second transmission wheel 611 meshes with the second driving wheel 608; A pulling rope 10 and an auxiliary rope 14 are respectively arranged on the first winding roller 605 and the second winding roller 609. And a connecting member 13 is arranged on one side of the template 2 close to the guiding wheel. One end of the auxiliary rope 14 is located on the connecting member 13. And one end of the pulling rope 10 away from the first winding roller 605 is fixedly connected with the template 2; Guiding rollers 9 are arranged on one side of the fixing frame 601 close to the template 2. The guiding rollers 9 cooperate with the surface of the template 2. And a concrete pier 8 is poured between the templates 2; After the first driving motor 602 is started, the power is transmitted to the first driving wheel 604 through the rotating shaft 603. The meshing of the first driving wheel 604 and the first transmission wheel 606 transmits the rotational motion to the first winding roller 605. As the first winding roller 605 rotates, the pulling rope 10 is wound up and retracted, directly pulling the template 2 to rise along the guiding frame 12. The second driving motor 610 works synchronously, driving the second driving wheel 608 to drive the second transmission wheel 611, so that the second winding roller 609 rotates. The auxiliary rope 14 is connected with the template 2 through the connecting member 13. While the pulling rope 10 lifts the template 2, the auxiliary rope 14 provides a balancing pulling force; The first driving motor 602 and the second driving motor 610 are independently powered and work together. In the normal working state, the two motors rotate at the same speed to ensure that the pulling rope 10 and the auxiliary rope 14 are wound up and released synchronously, ensuring the stable rise of the template 2. When the position of the template 2 needs to be finely adjusted, the rotational speeds of the two motors can be adjusted respectively through the control system. If the template 2 tilts to the left, the rotational speed of the first driving motor 602 on the left can be appropriately increased to accelerate the winding speed of the pulling rope 10. At the same time, the rotational speed of the second driving motor 610 on the left is reduced, so that the winding speed of the auxiliary rope 14 is slowed down, so that the template 2 is finely adjusted to the right to achieve the control of the vertical accuracy; The guiding rollers 9 on the fixing frame 601 are in rolling contact with the surface of the template 2, forming a rolling friction pair. When the template 2 rises, the guiding rollers 9 not only limit the horizontal displacement of the template 2, but also reduce the sliding resistance, ensuring that the template 2 climbs precisely along the predetermined track. During the concrete pouring process of the concrete forming aid, the guiding rollers 9 also play a supporting role on the template 2, offsetting the deformation caused by the lateral pressure of the concrete.
