Description

TECHNICAL FIELD

[0001] The present application relates to the field of steel bridge launching, mainly used for the construction of continuous bridges or steel structure bridges. Launching construction technology is a method of building bridges by assembling steel beam segments at one end (or both ends) of the bridge, and then pushing the beam body from the fulcrum to the final position with the help of launching equipment (such as hydraulic jacks), until the bridge completely spans the target interval. Specifically, it is a kind of steel bridge launching device and its using method. BACKGROUND

[0002] Steel bridges are a type of bridge structure mainly made of steel. They are widely used in modern bridge engineering due to their high strength, light weight, convenient construction and strong adaptability. They are usually used in large-span bridges, high-load traffic bridges and projects that require rapid construction. The advantages of steel bridges are: high strength and light weight: steel has high strength and relatively light weight, which is beneficial to the construction of large-span bridges. Good plasticity and toughness: good performance under earthquake or other sudden loads. Factory manufacturing: steel components can be processed in factories and assembled at construction sites, greatly improving construction efficiency. Strong maintainability: easy to inspect, maintain and replace components, prolonging the service life of the bridge.

[0003] Steel bridge launching is a method of bridge construction, mainly used for the construction of continuous bridges or steel structure bridges. Launching construction technology is a method of building bridges by assembling steel beam segments at one end (or both ends) of the bridge, and then pushing the beam body from the fulcrum to the final position with the help of launching equipment (such as hydraulic jacks), until the bridge completely spans the target interval. The process of launching construction: steel beams are manufactured in sections at the assembly site near the abutment, usually 10-30 meters long. After sectional assembly is completed, ensure that the quality and geometric dimensions meet the design requirements. Install slides, supports and sliding devices at the starting end of the bridge and the top of the pier. The slide is usually made of low-friction material (such as polytetrafluoroethylene plate) to reduce the pushing resistance. Use other pushing devices to push the bridge beam body forward in sections. Each time the beam body moves forward by the length of a beam segment. After the new beam segment is assembled at the rear, continue to push. During construction, a guide beam (a temporary steel structure used to reduce the front cantilever bending moment during launching) is usually installed at the front end of the beam body. After launching is completed, adjust the beam body to the design position and install the permanent supports of the bridge. After launching is completed, perform subsequent construction such as concrete paving and guardrail installation on the bridge deck.

[0004] The existing pushing device may be partially disconnected in the contact surface when facing the arch bridge or the steel bridge with the arc, which leads to slow pushing efficiency and even safety accidents. This situation may increase the sliding resistance, uneven stress, even cause the deformation of the slide or the failure of the pushing device, thereby affecting the construction efficiency and safety. The beam body of the steel arch bridge or the arc bridge is not straight, and the slide is usually arranged horizontally. If the surface shape of the slide is not designed to adapt, the beam body may be partially connected with the slide to bear the sliding force. Therefore, there is an urgent need for a steel bridge pushing device and a using method thereof to solve this problem.

[0005] Therefore, based on years of experience in design, development and actual production in the related industry, the applicant provides a steel bridge pushing device and a using method thereof to solve the problems of the prior art. SUMMARY

[0006] (I) Technical problems to be solved

[0007] In view of the deficiencies of the prior art, the present application provides a steel bridge pushing device and a using method thereof, which solves the problem that the existing pushing device may be partially disconnected in the contact surface when facing the arch bridge or the steel bridge with the arc, which leads to slow pushing efficiency and even safety accidents. This situation may increase the sliding resistance, uneven stress, even cause the deformation of the slide or the failure of the pushing device, thereby affecting the construction efficiency and safety.

[0008] (II) Technical solutions

[0009] To achieve the above purpose, the present application is realized by the following technical solutions: a steel bridge pushing device, comprising a mounting seat, a pushing and lifting oil cylinder, a translation mechanism, a connecting assembly and a pushing assembly. The device is designed scientifically and reasonably, and can adapt to different bridge structures and construction requirements. The pushing and lifting oil cylinder is fixed on the mounting support table in a reverse installation mode, and is used to provide powerful lifting power to ensure that the beam body rises smoothly during construction. The mounting seat is provided above the pushing and lifting oil cylinder and is the key bearing part of the whole device, which connects and supports the upper mechanism.

[0010] The translation mechanism is installed above the mounting seat and is responsible for realizing the lateral sliding or adjustment of the bridge beam body to ensure accurate positioning during pushing. The pushing assembly is fixed on the translation mechanism through the connecting assembly to realize the unified action of the whole device. The core part of the pushing assembly includes an adjusting oil cylinder and an adjusting rod. The adjusting oil cylinder controls the extension and retraction state of the adjusting rod to realize flexible adjustment of the height, so that the pushing assembly can adjust the inclination angle according to the design arc or structural characteristics of the bridge. This design effectively solves the problems of low pushing efficiency and disconnected contact surface caused by the change of the arc of the beam body in the construction of the steel bridge.

[0011] By optimizing the combination of each component and the adjustment capability, the device can adapt to the incremental launching construction requirements of various complex bridges, improve the construction efficiency and ensure the operation safety.

[0012] Preferably, a control box is installed on the side of the mounting seat for centralized control of various operations of the device, improving the safety and operability of the equipment operation. Above the mounting seat, a horizontal oil cylinder is installed, which is remotely controlled through the control box and connected through a connecting line to ensure the timeliness and accuracy of signal transmission. The side of the horizontal oil cylinder is provided with a horizontal push rod connected to the side of the translation mechanism to transfer power. The horizontal push rod can realize accurate adjustment of the translation mechanism under the drive of the horizontal oil cylinder, thereby ensuring accurate control of the beam position and operation stability during the incremental launching of the steel bridge. This design provides the incremental launching device with efficient and accurate translation adjustment capability, suitable for complex bridge construction requirements.

[0013] Preferably, the upper surface of the mounting seat is designed as a contact surface and the surface is finely smoothed to ensure smooth operation of the translation mechanism during sliding. In order to further optimize the performance of the device, the material and surface treatment technology of the contact surface are carefully designed, and the static friction coefficient is strictly controlled within the range of less than 0.1. Such a low friction coefficient effectively reduces the resistance in the sliding process, reduces power consumption, and avoids wear and heating problems caused by friction. This design significantly improves the working efficiency of the translation mechanism, ensuring the smoothness and continuity of the bridge incremental launching operation. Even under long-distance sliding or complex construction conditions, the reliability and durability of the device can be ensured, thereby improving the overall construction efficiency and prolonging the service life of the device.

[0014] Preferably, a limiting guide rod is provided on the contact surface, and the limiting guide rod adopts a cross-shaped layout. Such a design aims to provide the translation mechanism with multi-directional limiting guide function, effectively avoiding the problems of mechanism deviation or instability caused by external force or deviation. During the incremental launching construction process, the translation mechanism needs to withstand complex stress from different directions. The reasonable arrangement of the cross-shaped limiting guide rod can not only accurately constrain the movement trajectory, but also ensure the stability and reliability of the translation mechanism during displacement.

[0015] In addition, the cross-shaped limiting guide rod allows the translation mechanism to slide smoothly even under heavy load, which helps to reduce vibration and impact and improve the accuracy of construction. This design enhances the anti-interference ability of the equipment, ensures the safety and efficiency of the incremental launching process, and prolongs the service life of the device.

[0016] Preferably, the jacking oil cylinder is composed of a jacking rod, a jacking base and anti-skid patterns, and the overall design takes into account both structural strength and use stability. The jacking rod is the extending part of the jacking oil cylinder, which is used to provide jacking power and transmit thrust to the bridge body or other construction sites. The jacking base is located at the lower end of the jacking rod and serves as an important component connecting the jacking oil cylinder and the temporary support, and its design directly affects the stability and jacking effect of the entire device.

[0017] Preferably, the jacking base adopts a ladder-shaped design, which not only effectively disperses the stress but also enhances the load-carrying capacity of the base. To further improve the anti-skid performance of the base, the bottom surface is provided with wave-shaped anti-skid patterns, which are distributed in a ring array and can provide uniform anti-skid ability in all directions. When the jacking oil cylinder is working, this anti-skid pattern structure closely adheres to the surface of the temporary support, effectively preventing slipping or displacement even under high load or complex environment.

[0018] Through this design, the jacking oil cylinder can maintain a stable and reliable working state during jacking, ensuring construction safety and improving the accuracy and efficiency of jacking operations.

[0019] Preferably, the structure of the translation mechanism includes a translation plate, a mounting slot, a limiting slot, a connecting rod and a mounting block, and each component cooperates with each other to form a complete and efficient displacement adjustment system. The translation plate is the core component of the mechanism and is installed above the mounting seat as the load-carrying platform of the entire translation mechanism. The side of the translation plate is provided with a mounting slot to facilitate the assembly and fixation of other components, and at the same time, the flexibility of the overall structure is enhanced.

[0020] Preferably, a limiting slot is provided below the translation plate to limit its movement range, ensuring the stability of the trajectory during translation and avoiding displacement deviation. The adjusting oil cylinder is installed above the translation plate as the power source to provide precise control for translation adjustment. The upper end of the adjusting oil cylinder is connected with a connecting rod, which plays a role in force transmission and transmits the extension and retraction movement of the oil cylinder to the adjusting rod.

[0021] The adjusting rod is fixed above the connecting rod, and the mounting block is arranged at the ends of the adjusting rod for connecting other equipment or transmitting stress. The overall design makes the translation mechanism have good adjustment ability and running stability, which can meet the diversified construction needs and improve the efficiency and accuracy of construction.

[0022] Preferably, the mounting block is designed in a petal shape, with its surface composed of multiple arc-shaped blocks. This structure fully embodies the combination of functionality and aesthetic design. The arc-shaped blocks are arranged in precise arcs, forming evenly distributed contact surfaces that enable the mounting block to perfectly match the connecting assembly. During device operation, the matching relationship between the connecting assembly and the mounting block is particularly critical. The petal-shaped structure has the advantage of allowing the connecting assembly to quickly rotate when needed, thereby flexibly adjusting the angle to meet different construction needs.

[0023] More importantly, the arc-shaped blocks and their corresponding arc-shaped grooves are tightly fitted, giving the connecting assembly a certain degree of self-locking function. When external force is applied, the arc-shaped structure can effectively disperse stress and reduce local wear, while relying on its unique geometry to achieve stable locking, preventing accidental loosening or deviation. This design not only improves the adjustment efficiency of the device, but also enhances safety and stability during construction. Through the application of the petal-shaped mounting block, the entire device has high flexibility and reliability, suitable for various complex bridge construction scenarios.

[0024] Preferably, the connecting assembly includes a connecting ring, a matching groove, and a connecting block, with the overall design facilitating precise connection and cooperation between components. The connecting ring is installed on the outside of the mounting block and serves as the core component of the connecting assembly, providing a stable connection platform. The middle part of the connecting ring is provided with a matching groove for precise cooperation with other components to ensure stable connection. The connecting block is installed on the surface of the connecting ring and can achieve firm connection through cooperation with the matching groove, providing quick disassembly and adjustment functions when needed. This design enhances the flexibility and stability of the connection, enabling the entire device to operate smoothly in complex construction environments.

[0025] Preferably, the pushing assembly includes a pushing plate and anti-slip ridges, designed to improve pushing effect and extend device service life. The pushing plate is installed above the connecting assembly and serves as the main bearing surface of the pushing device, directly contacting the steel bridge and transmitting the pushing force. To improve friction during pushing, anti-slip ridges are provided on the top of the pushing plate, and the design of the ridges effectively enhances the contact stability between the pushing plate and the steel bridge. The anti-slip ridges are distributed in a mirror image on the pushing plate, ensuring that during the entire pushing process, whether it is horizontal or vertical movement, uniform and effective friction can be provided to reduce the phenomenon of slipping.

[0026] A method for using a steel bridge pushing device, including the steel bridge pushing device, the specific operation is as follows,

[0027] S1: During operation, the worker installs the temporary support near the pier, first installs and fixes the pushing base on the top of the temporary support,

[0028] S2: The horizontal oil cylinder, adjusting oil cylinder and push-up oil cylinder are controlled by the control box to work; then the control box is adjusted to move the translation mechanism to the specified position, so that different inclination angles of the push-up plate are realized;

[0029] S3: The push-up oil cylinder is further worked to move the mounting seat to the contact between the push-up plate and the steel bridge;

[0030] S4: The horizontal oil cylinder is further worked to move the translation mechanism horizontally, so that the multiple push-up plates disperse to push the steel bridge to realize the push-up movement, and finally realize the push-up work.

[0031] (Three)beneficial effects

[0032] The application provides a steel bridge pushing device and a use method thereof.

[0033] (1) According to the design radius of the bridge, the pushing device is customized to match the shape of the lower edge of the beam body, and the inclination angle or height of the slide is adjusted by using the pushing device support structure, so that the radius of the beam body is dynamically adapted

[0034] (2) This structure not only improves the friction between the pushing assembly and the steel bridge, but also enhances the wear resistance, reduces the wear and damage caused by friction, and effectively prolongs the service life of the equipment.

The device is designed scientifically and reasonably, and can adapt to different bridge structures and construction requirements. The push lifting oil cylinder 8 is installed in reverse, fixed on the mounting support table, used to provide powerful lifting power to ensure the smooth lifting of the beam body during construction. The mounting seat 1 is installed above the push lifting oil cylinder 8, which is the key load-bearing component of the whole device, connecting and supporting the upper mechanism.

[0047] The translation mechanism 9 is installed above the mounting seat 1, responsible for realizing the lateral sliding or adjustment of the bridge beam body, ensuring accurate positioning during pushing. The pushing assembly 11 is fixed on the translation mechanism 9 through the connecting assembly 10, realizing the unified action of the whole device. The core part of the pushing assembly 11 includes an adjusting oil cylinder 94 and an adjusting rod 96. The adjusting oil cylinder 94 adjusts the height by controlling the extension and retraction state of the adjusting rod 96, so that the pushing assembly 11 can adjust the inclination angle according to the design curvature or structural characteristics of the bridge. This design effectively solves the problems of low pushing efficiency and empty contact of the contact surface 6 caused by the change of the curvature of the beam body during the construction of the steel bridge.

Above the mounting base 1, a horizontal oil cylinder 4 is installed, which is remotely controlled by the control box 2 and connected thereto through a connecting line 3 to ensure the timeliness and accuracy of signal transmission. The side of the horizontal oil cylinder 4 is provided with a horizontal push rod 5 connected to the side of the translation mechanism 9, which plays a role in transmitting power. The horizontal push rod 5 can realize accurate adjustment of the translation mechanism 9 under the drive of the horizontal oil cylinder 4, thereby ensuring accurate control of the position of the beam body during the pushing process of the steel bridge and the stability of the operation. This design provides efficient and accurate translation adjustment capability for the pushing device, which is suitable for complex bridge construction requirements.

[0049] As shown in Figure 2 The upper surface of the mounting base 1 is designed as a contact surface 6, and the surface is finely smoothed to ensure smooth operation of the translation mechanism 9 during sliding. In order to further optimize the performance of the device, the material and surface treatment technology of the contact surface 6 are carefully designed, and its static friction coefficient is strictly controlled within the range of less than 0.1. Such a low friction coefficient effectively reduces the resistance in the sliding process, reduces power consumption, and avoids wear and heating problems caused by friction.

Such a design aims to provide multi-directional limiting guide function for the translation mechanism 9, effectively avoiding the problem of mechanism deviation or instability caused by external force or deviation. During the pushing construction process, the translation mechanism 9 needs to bear complex stress from different directions, and the reasonable arrangement of the cross-shaped limiting guide rod 7 can not only accurately constrain its movement trajectory, but also ensure its stability and reliability during displacement.

[0051] In addition, the arrangement of the cross-shaped limiting guide rod 7 enables the translation mechanism 9 to slide smoothly even under heavy load, which helps to reduce vibration and impact and improve the accuracy of construction. This design enhances the anti-interference ability of the equipment, ensures safe and efficient pushing process, and prolongs the service life of the device.

[0052] The lifting oil cylinder 8 is composed of a lifting rod 81, a lifting base 82 and anti-skid lines 83, and the overall design takes into account the structural strength and use stability. The lifting rod 81 is the protruding part of the lifting oil cylinder 8, which is used to provide lifting power and transmit thrust to the bridge body or other construction sites. The lifting base 82 is located at the lower end of the lifting rod 81 and serves as an important component connecting the lifting oil cylinder 8 and the temporary support, and its design directly affects the stability and jacking effect of the entire device.

[0053] As shown in Figure 4 , the lifting base 82 adopts a ladder-shaped design, which not only effectively disperses the stress, but also enhances the carrying capacity of the base. To further improve the anti-skid performance of the base, the bottom surface is provided with wave-shaped anti-skid lines 83, which are arranged in a ring array and can provide uniform anti-skid ability in all directions. When the lifting oil cylinder 8 is working, the anti-skid lines 83 structure closely fits the surface of the temporary support, which can effectively prevent slipping or displacement even under high load or complex environment.

[0054] Through this design, the lifting oil cylinder 8 can maintain a stable and reliable working state during the lifting process, ensuring construction safety and improving the accuracy and efficiency of the jacking operation.

[0055] As shown in Figure 5 , the structure of the translation mechanism 9 includes a translation plate 91, a mounting groove 92, a limiting groove 93, a connecting rod 95 and a mounting block 97, which cooperate with each other to form a complete and efficient displacement adjustment system. The translation plate 91 is the core component of the mechanism and is installed above the mounting seat 1 as the bearing platform of the entire translation mechanism 9. The side surface of the translation plate 91 is provided with a mounting groove 92, which facilitates the assembly and fixation of other components and enhances the flexibility of the overall structure.

[0056] A limiting groove 93 is provided below the translation plate 91 to limit its movement range and ensure the stability of the trajectory during translation to avoid displacement deviation. The adjusting oil cylinder 94 is installed above the translation plate 91 as the power source to provide precise control for translation adjustment. The upper end of the adjusting oil cylinder 94 is connected with the connecting rod 95, which plays a role in force transmission and transmits the extension and retraction movement of the oil cylinder to the adjusting rod 96.

[0057] The adjusting rod 96 is fixed above the connecting rod 95, and the mounting block 97 is arranged at the ends of the adjusting rod 96 for connecting other equipment or transmitting stress. The overall design makes the translation mechanism 9 have good adjustment ability and running stability, which can meet the diversified construction needs and improve the efficiency and accuracy of construction.

[0058] The installation block 97 is designed in a petal shape, with its surface composed of multiple arc-shaped blocks. This structure fully embodies the combination of functionality and aesthetic design. The arc-shaped blocks are arranged with precise curvature, forming evenly distributed contact surfaces 6, allowing the installation block 97 to perfectly match the connecting assembly 10. During the operation of the device, the matching relationship between the connecting assembly 10 and the installation block 97 is particularly critical. The petal-shaped structure has the advantage of allowing the connecting assembly 10 to quickly rotate when needed, thereby flexibly adjusting the angle to meet different construction requirements.
