Description

Technical Field

[0001] The present invention relates to the field of steel bridge jacking, and is mainly used for the construction of continuous bridges or steel structure bridges. The jacking construction technology assembles the steel beam sections of the bridge section by section at one end (or both ends) of the bridge, and then pushes the beam body from the fulcrum to the final position with the help of jacking equipment (such as hydraulic jacks) until the bridge completely crosses the target interval. Specifically, it is a steel bridge jacking device and a method for using the same. Background Art

[0002] Steel bridges are a type of bridge structure made mainly of steel. They are widely used in modern bridge engineering because of their high strength, light weight, convenient construction and strong adaptability. They are usually used for long-span bridges, high-load traffic bridges and engineering projects that require rapid construction. Advantages of steel bridges: High strength and light weight: Steel has high strength and relatively light weight, which is conducive to the construction of long-span bridges. Good plasticity and toughness: It performs better under earthquakes or other sudden loads. Factory manufacturing: Steel components can be processed in the factory and assembled on the construction site, greatly improving construction efficiency. Strong maintainability: It is easy to inspect, maintain and replace components, extending the life of the bridge.

[0003] Steel bridge jacking is a bridge construction method mainly used for the construction of continuous bridges or steel structure bridges. The jacking construction technology assembles the steel beam segments of the bridge one by one at one end (or both ends) of the bridge, and then pushes the beam body from the support to the final position with the help of jacking equipment (such as hydraulic jacks) until the bridge completely spans the target interval. The process of jacking construction: The steel beam is manufactured in sections at the assembly site near the abutment, usually each section is 10 to 30 meters long. After the section assembly is completed, ensure that the quality and geometric dimensions meet the design requirements. Install slideways, bearings and sliding devices at the starting end of the bridge and the top of the pier. The slideway usually uses low-friction materials (such as polytetrafluoroethylene plates) to reduce thrust resistance. Use other pushing devices to push the bridge beam forward section by section. Each time it is pushed, the beam body will move forward by the length of a beam section. The new beam section will continue to be pushed after the rear assembly is completed. During the construction process, a guide beam is usually installed at the front end of the beam body (the guide beam is a temporary steel structure used to reduce the front cantilever bending moment during jacking). After the jacking is completed, the beam is adjusted to the designed position and the permanent bearings of the bridge are installed. After the jacking is completed, subsequent construction such as concrete paving and guardrail installation is carried out on the bridge deck.

[0004] When the existing jacking devices are used on arch bridges or curved steel bridges, the contact surface may be partially empty, resulting in slow jacking efficiency and even safety accidents. This situation may increase the sliding resistance, uneven force, and even cause the slideway to deform or the jacking device to fail, thus affecting the construction efficiency and safety. The beams of steel arch bridges or curved bridges are not straight lines, and the slideways are usually arranged horizontally. If the surface shape of the slideway is not adaptively designed, the beam may not be in full contact with the slideway, and only part of the area will bear the sliding force. Therefore, there is an urgent need for a steel bridge jacking device and a method of using it to solve this problem.

[0005] Therefore, the applicant, based on many years of rich experience in design, development and actual production in the relevant industry, has conducted research and improvements on the existing structures and deficiencies, and provided a steel bridge jacking device and a method of use thereof, in order to achieve a more practical purpose. Summary of the invention

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the present invention provides a steel bridge jacking device and a method for using the same, which solves the problem that when the existing jacking device faces an arch bridge or a curved steel bridge, the contact surface may be partially empty, resulting in slow jacking efficiency and even safety accidents. This situation may lead to increased sliding resistance, uneven force, and even cause deformation of the slideway or failure of the jacking device, thereby affecting construction efficiency and safety.

[0008] (II) Technical solution

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions: a steel bridge jacking device, including a mounting seat, a lifting cylinder, a translation mechanism, a connecting assembly and a pushing assembly. The device is scientifically designed and reasonably structured, and can adapt to different bridge structures and construction requirements. The lifting cylinder is reversely installed and fixed on the mounting bracket to provide powerful lifting power to ensure that the beam body rises smoothly during the construction process. A mounting seat is arranged above the lifting cylinder, which is the key load-bearing component of the entire device, connecting and supporting the upper mechanism.

[0010] A translation mechanism is installed above the mounting seat, which is responsible for realizing the lateral sliding or adjustment of the bridge beam body to ensure accurate positioning during the jacking process. The jacking assembly is fixed to the translation mechanism through a connecting assembly to achieve unified movement of the entire device. The core part of the jacking assembly includes an adjusting cylinder and an adjusting rod. The adjusting cylinder controls the telescopic state of the adjusting rod to achieve flexible height adjustment, so that the jacking assembly can adjust the inclination angle according to the design curvature or structural characteristics of the bridge. This design effectively solves the problems of low jacking efficiency and empty contact surface caused by changes in the curvature of the beam body during steel bridge construction.

[0011] By optimizing the combination and adjustment capabilities of various components, the device can adapt to the jacking construction needs of various complex bridges, improve construction efficiency and ensure operation safety.

[0012] Preferably, a control box is installed on the side of the mounting seat, and the control box is used to centrally control various operations of the device to improve the safety and operability of the equipment operation. A horizontal cylinder is installed above the mounting seat, and the horizontal cylinder is remotely controlled by the control box. The control box is connected to the horizontal cylinder by a connecting line to ensure the timeliness and accuracy of signal transmission. A horizontal push rod is provided on the side of the horizontal cylinder, and the push rod is connected to the side of the translation mechanism to transmit power. Driven by the horizontal cylinder, the horizontal push rod can realize the precise adjustment of the translation mechanism, thereby ensuring the precise control of the beam position and operational stability during the jacking process of the steel bridge. This design provides the jacking device with efficient and precise translation adjustment capabilities, which is suitable for complex bridge construction requirements.

[0013] Preferably, the upper surface of the mounting seat is designed as a contact surface, and its surface is finely smoothed to ensure that the translation mechanism can operate smoothly during the sliding process. In order to further optimize the performance of the device, the material and surface treatment technology of the contact surface 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 during the sliding process, reduces power consumption, and avoids wear and heat problems caused by friction. This design significantly improves the working efficiency of the translation mechanism, ensures the stability and continuity of the bridge jacking operation, and ensures the reliability and durability of the device even under long-distance sliding or complex construction conditions, thereby improving the overall construction efficiency and extending the service life of the device.

[0014] Preferably, the contact surface is provided with a limit guide rod, which is arranged in a cross shape. Such a design is intended to provide a multi-directional limit guide function for the translation mechanism, effectively avoiding the problem of deviation or instability of the mechanism caused by external force or offset. During the jacking construction process, the translation mechanism needs to withstand complex forces from different directions. The reasonable arrangement of the cross-shaped limit guide rod can not only accurately constrain its motion trajectory, but also ensure its stability and reliability during the displacement process.

[0015] In addition, the setting of the cross-shaped limit guide rod enables 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 jacking process, and prolongs the service life of the device.

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

[0017] Preferably, the lifting base adopts a stepped design, which can not only effectively disperse the force, but also enhance the bearing capacity of the base. In order to further improve the anti-skid performance of the base, a wavy anti-skid pattern is provided on the bottom surface thereof, and the anti-skid pattern is distributed in a circular array, which can provide uniform anti-skid ability in all directions. When the lifting cylinder is working, this anti-skid pattern structure fits tightly with the surface of the temporary support, and can effectively prevent slippage or displacement even under high load or complex environment.

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

[0019] Preferably, the structure of the translation mechanism includes a translation plate, a mounting slot, a limit 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, which is installed above the mounting seat and serves as a bearing platform for 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 enhance the flexibility of the overall structure.

[0020] Preferably, a limit groove is provided under the translation plate to limit its range of movement, ensure the stability of the trajectory during translation, and avoid displacement deviation. The adjustment cylinder is installed above the translation plate as a power source to provide precise control for translation adjustment. The upper end of the adjustment cylinder is connected to a connecting rod, which plays a role in transmitting force and transmits the telescopic movement of the cylinder to the adjustment rod.

[0021] The adjusting rod is fixed on the top of the connecting rod, and a mounting block is set at its end. The mounting blocks are arranged at both ends of the adjusting rod to connect other equipment or transmit force. The overall design enables the translation mechanism to have good adjustment ability and operation stability, which can meet the diverse construction needs and improve the efficiency and accuracy of construction.

[0022] Preferably, the mounting block is designed to be petal-shaped, and its surface is composed of multiple arc-shaped blocks. This structure fully reflects the combination of functionality and design aesthetics. The arc-shaped blocks are arranged with precise arcs to form a uniformly distributed contact surface, so that the mounting block can perfectly match the connecting component. During the operation of the device, the matching relationship between the connecting component and the mounting block is particularly critical. The advantage of the petal-shaped structure is that it allows the connecting component to rotate quickly when needed, so as to flexibly adjust the angle to meet different construction requirements.

[0023] More importantly, the arc block and its corresponding arc groove fit tightly together, giving the connection assembly a certain degree of self-locking function. When external force is applied, the arc structure can effectively disperse stress and reduce local wear. At the same time, its unique geometric shape can achieve a firm lock to prevent accidental loosening or displacement. This design not only improves the adjustment efficiency of the device, but also enhances the safety and stability during the construction process. Through the application of petal-shaped mounting blocks, the entire device has high flexibility and reliability, and is suitable for a variety of complex bridge construction scenarios.

[0024] Preferably, the connection assembly includes a connection ring, a matching groove and a connection block, and the overall design facilitates precise connection and matching between the various components. The connection ring is installed on the outside of the mounting block, and as the core component of the connection assembly, it provides a stable connection platform. A matching groove is provided in the middle part of the connection ring for precise matching with other components to ensure a stable connection. The connection block is installed on the surface of the connection ring, and through the corresponding matching with the matching groove, a firm connection can be achieved, and the function of quick disassembly and adjustment can be provided when necessary. This design enhances the flexibility and stability of the connection, allowing the entire device to operate smoothly in a complex construction environment.

[0025] Preferably, the pushing assembly includes a pushing plate and anti-skid convex strips, which are designed to improve the pushing effect and extend the service life of the device. 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 thrust. In order to increase the friction during the pushing process, the anti-skid convex strips are arranged on the pushing plate. The design of the convex strips effectively enhances the contact stability between the pushing plate and the steel bridge. The anti-skid convex strips are distributed on the pushing plate in a mirror-image manner to ensure that uniform and effective friction can be provided during the entire pushing process, whether it is lateral or longitudinal movement, thereby reducing slippage.

[0026] A method for using a steel bridge pushing device, including the steel bridge pushing device, is specifically operated as follows:

[0027] S1: During the work, the staff installed the temporary support near the bridge pier, and first fixed the push-up base on the temporary support.

[0028] S2: The horizontal cylinder, the adjusting cylinder and the lifting cylinder are controlled by the control box to work; the translation mechanism is then adjusted by the control box to specifically adjust the cylinder displacement to a specified position, thereby achieving different tilt angles of the push plate;

[0029] S3: Let the lifting cylinder work again to move the mounting seat until the push plate contacts the steel bridge;

[0030] S4: Then the horizontal oil cylinder is operated to make the translation mechanism move horizontally, so that multiple jacking plates dispersedly push the steel bridge to achieve jacking movement, and finally the jacking work is completed.

[0031] (III) Beneficial effects

[0032] The present invention provides a steel bridge jacking device and a method for using the same. The device has the following beneficial effects:

[0033] (1) According to the designed curvature of the bridge, a pushing device is customized for the pushing slideway to match the shape of the lower edge of the beam. The pushing device support structure is used to adjust the inclination or height of the slideway to dynamically adapt to the curvature of the beam.

[0034] (2) This structure not only improves the friction between the jacking assembly and the steel bridge, but also enhances wear resistance, reduces wear and damage caused by friction, and effectively extends the service life of the equipment. By optimizing the design of the anti-slip convex strips, the jacking assembly can maintain efficient thrust transmission and stability during long-term use, ensuring the smooth progress of the construction process.

DETAILED DESCRIPTION

[0045] Now, in conjunction with the accompanying drawings and embodiments, a novel gantry crane track foundation and a construction method thereof proposed by the present invention will be further described.

[0046] like Figure 1-7 As shown, a steel bridge jacking device includes a mounting seat 1, a lifting cylinder 8, a translation mechanism 9, a connecting assembly 10 and a jacking assembly 11. The device is scientifically designed and reasonably structured, and can adapt to different bridge structures and construction requirements. The lifting cylinder 8 is reversely installed and fixed on the mounting bracket to provide a strong lifting power to ensure that the beam body is lifted smoothly during the construction process. A mounting seat 1 is set above the lifting cylinder 8, which is the key load-bearing component of the entire device and connects and supports the upper mechanism.

[0047] A translation mechanism 9 is installed above the mounting seat 1, which is responsible for realizing the lateral sliding or adjustment of the bridge beam body to ensure accurate positioning during the jacking process. The jacking assembly 11 is fixed to the translation mechanism 9 through the connecting assembly 10 to realize the unified action of the entire device. The core part of the jacking assembly 11 includes an adjusting cylinder 94 and an adjusting rod 96. The adjusting cylinder 94 realizes flexible adjustment of the height by controlling the telescopic state of the adjusting rod 96, so that the jacking 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 jacking efficiency and empty contact of the contact surface 6 caused by the change of the curvature of the beam body in the construction of steel bridges.

[0048] A control box 2 is installed on the side of the mounting base 1. The control box 2 is used to centrally control various operations of the device to improve the safety and operability of the equipment operation. A horizontal cylinder 4 is installed above the mounting base 1. The horizontal cylinder 4 is remotely controlled by the control box 2 and is connected to it by a connecting line 3 to ensure the timeliness and accuracy of signal transmission. A horizontal push rod 5 is arranged on the side of the horizontal cylinder 4. The push rod is connected to the side of the translation mechanism 9 to transmit power. Driven by the horizontal cylinder 4, the horizontal push rod 5 can realize the precise adjustment of the translation mechanism 9, thereby ensuring the precise control of the beam position and the operational stability during the jacking process of the steel bridge. This design provides the jacking device with efficient and precise translation adjustment capabilities, which is suitable for complex bridge construction requirements.

[0049] like Figure 2 As shown, the upper surface of the mounting seat 1 is designed as a contact surface 6, and its surface is finely smoothed to ensure that the translation mechanism 9 can operate smoothly during the sliding process. In order to further optimize the performance of the device, the material and surface treatment technology of the contact surface 6 have been 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 during the sliding process, reduces power consumption, and avoids wear and heat problems caused by friction. This design significantly improves the working efficiency of the translation mechanism 9, ensures the stability and continuity of the bridge jacking operation, and ensures the reliability and durability of the device even under long-distance sliding or complex construction conditions, thereby improving the overall construction efficiency and extending the service life of the device.

[0050] The contact surface 6 is provided with a limit guide rod 7, which is arranged in a cross shape. Such a design is intended to provide a multi-directional limit guide function for the translation mechanism 9, effectively avoiding the problem of deviation or instability of the mechanism caused by external force or offset. During the jacking construction process, the translation mechanism 9 needs to withstand complex forces from different directions. The reasonable arrangement of the cross-shaped limit guide rod 7 can not only accurately constrain its motion trajectory, but also ensure its stability and reliability during the displacement process.

[0051] In addition, the setting 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 the safety and efficiency of the jacking process, and prolongs the service life of the device.

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

[0053] like Figure 4 As shown, the lifting base 82 adopts a stepped design, which can not only effectively disperse the force, but also enhance the bearing capacity of the base. In order to further improve the anti-skid performance of the base, a wavy anti-skid pattern 83 is provided on its bottom surface. The anti-skid pattern 83 is distributed in a circular array and can provide uniform anti-skid ability in all directions. When the lifting cylinder 8 is working, this anti-skid pattern 83 structure fits tightly with the surface of the temporary support, and can effectively prevent slippage or displacement even under high load or complex environment.

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

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

[0056] A limit slot 93 is provided below the translation plate 91 to limit its range of movement, ensure the stability of the trajectory during translation, and avoid displacement deviation. An adjustment cylinder 94 is installed above the translation plate 91 as a power source to provide precise control for translation adjustment. A connecting rod 95 is connected to the upper end of the adjustment cylinder 94, which plays a role in transmitting force and transmitting the telescopic movement of the cylinder to the adjustment rod 96.

[0057] The adjusting rod 96 is fixed on the top of the connecting rod 95, and a mounting block 97 is provided at the end thereof. The mounting block 97 is arranged at both ends of the adjusting rod 96 for connecting other equipment or transmitting force. The overall design enables the translation mechanism 9 to have good adjustment ability and operation stability, which can meet various construction needs and improve the efficiency and accuracy of construction.

[0058] The mounting block 97 is designed in a petal shape, and its surface is composed of multiple arc blocks. This structure fully reflects the combination of functionality and design aesthetics. The arc blocks are arranged in a precise arc to form a uniformly distributed contact surface 6, so that the mounting block 97 can perfectly match the connecting component 10. During the operation of the device, the matching relationship between the connecting component 10 and the mounting block 97 is particularly critical. The advantage of the petal-shaped structure is that it allows the connecting component 10 to rotate quickly when needed, so as to flexibly adjust the angle to meet different construction requirements.

[0059] More importantly, the arc block and its corresponding arc groove fit tightly together, giving the connection assembly 10 a certain degree of self-locking function. When external force is applied, the arc structure can effectively disperse stress and reduce local wear. At the same time, it relies on its unique geometric shape to achieve a stable lock to prevent accidental loosening or displacement. This design not only improves the adjustment efficiency of the device, but also enhances the safety and stability during the construction process. Through the application of the petal-shaped mounting block 97, the entire device has high flexibility and reliability, and is suitable for a variety of complex bridge construction scenarios.

[0060] like Figure 6 As shown, the connection assembly 10 includes a connection ring 101, a matching groove 102 and a connection block 103. The overall design facilitates precise connection and matching between the various components. The connection ring 101 is installed on the outside of the mounting block 97. As the core component of the connection assembly 10, it provides a stable connection platform. A matching groove 102 is provided in the middle part of the connection ring 101 for precise matching with other components to ensure a stable connection. The connection block 103 is installed on the surface of the connection ring 101. Through the corresponding matching with the matching groove 102, a firm connection can be achieved, and the function of quick disassembly and adjustment can be provided when necessary. This design enhances the flexibility and stability of the connection, allowing the entire device to operate smoothly in a complex construction environment.

[0061] like Figure 7 As shown, the jacking assembly 11 includes a jacking plate 111 and anti-skid convex strips 112, which are designed to enhance the jacking effect and extend the service life of the device. The jacking plate 111 is installed above the connecting assembly 10, and as the main bearing surface of the jacking device, it directly contacts the steel bridge and transmits the thrust. In order to increase the friction during the jacking process, the anti-skid convex strips 112 are arranged on the top of the jacking plate 111. The design of the convex strips effectively enhances the contact stability between the jacking plate 111 and the steel bridge. The anti-skid convex strips 112 are distributed in a mirror-image manner on the jacking plate 111, ensuring that uniform and effective friction can be provided during the entire jacking process, whether it is lateral or longitudinal movement, thereby reducing slippage.

[0062] This structure not only improves the friction between the jacking assembly 11 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. By optimizing the design of the anti-slip convex strips 112, the jacking assembly 11 can maintain efficient thrust transmission and stability during long-term use, ensuring the smooth progress of the construction process.

[0063] A method for using a steel bridge jacking device, a steel bridge jacking device, the specific operation is as follows:

[0064] S1: During the work, the staff installs a temporary support near the bridge pier, and first installs and fixes the push-up base 82 on the temporary support.

[0065] S2: The horizontal cylinder 4, the adjusting cylinder 94 and the lifting cylinder 8 are controlled by the control box 2 to work; the translation mechanism 9 is then adjusted by the control box 2, specifically adjusting the cylinder 94 to move to a specified position, thereby achieving different tilt angles of the push plate 111;

[0066] S3: Let the lifting cylinder 8 work again to move the mounting seat 1 until the push plate 111 contacts the steel bridge;

[0067] S4: The horizontal oil cylinder 4 is then operated to make the translation mechanism 9 move horizontally, so that a plurality of pushing plates 111 dispersedly push the steel bridge to achieve pushing movement, and finally achieve the pushing work.

[0068] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
