Description

Technical Field

[0001] This invention relates to the field of cap beam construction technology, and in particular to a cap beam support lifting system. Background Technology

[0002] In the field of bridge construction, the construction of bridge caps is a crucial step, and its efficiency and safety are of paramount importance. The cap support lifting system, as the core equipment ensuring the smooth progress of cap construction, directly determines the quality, schedule, and safety of the entire bridge project.

[0003] However, as bridge engineering continues to develop towards greater complexity and scale, more stringent requirements are being placed on girder support lifting systems. Currently, the shortcomings of some girder support lifting systems on the market in terms of adaptability and climbing stability are gradually becoming key factors restricting the high-quality development of bridge construction.

[0004] Existing cap beam support lifting systems suffer from poor adaptability when faced with piers of varying shapes and sizes, as well as complex and ever-changing construction environments. For example, patent CN116201021A discloses a movable cap beam support structure, which employs a fixed support frame design and is only suitable for piers of specific sizes and shapes. When encountering irregularly shaped structures such as inclined or curved piers, the support cannot fit tightly against the pier surface, resulting in significantly reduced installation stability and making it difficult to provide reliable support, severely limiting its application scope.

[0005] Stability during the climbing process is a crucial indicator of the performance of a girder support lifting system. However, some existing systems exhibit significant deficiencies in climbing stability. For instance, the climbing device disclosed in patent CN111648238A, lacking effective auxiliary support and buffering mechanisms, is prone to swaying and jamming during actual use, especially under heavy loads or complex geological conditions. This unstable climbing state not only affects construction efficiency but also increases safety risks, posing potential threats to construction personnel and equipment.

[0006] Therefore, a novel cap beam support lifting system is needed. This system can significantly expand the system's adaptability, enabling it to flexibly cope with piers of various shapes and sizes, as well as complex and ever-changing construction environments. Furthermore, it effectively reduces swaying and jamming during the climbing process, ensuring smooth climbing even under heavy loads or complex geological conditions. This greatly improves the overall stability of the system, providing a high-performance and highly reliable lifting system for bridge cap beam construction, and helping to promote the development of the bridge construction industry towards higher quality and higher efficiency. Summary of the Invention

[0007] The present invention aims to solve the problems of adaptability and climbing stability of the existing beam support lifting system in the prior art.

[0008] To solve the above problems, the present invention provides a cap beam support lifting system, comprising: The lifting and crawling device includes several lifting and crawling units connected end to end; The lifting and crawling unit includes an upper clamp unit and a lower clamp unit. An angle control device is provided between adjacent upper clamp units or lower clamp units.

[0012] Preferably, a rotating rod is connected between the rotating motor and the hinge seat. The rotating motor drives the hinge seat to rotate through the rotating rod. The rotating rod is equipped with a locking device, which includes a locking disc fixedly connected to the rotating rod and a braking device for limiting the rotation of the locking disc.

[0013] Preferably, the system also includes a control center. When the lifting and crawling device is performing the climbing operation on the pier, the control center operates the clamp locking device of the lower clamp unit to clamp and lock the pier, while the clamp locking device of the upper clamp unit moves away from the pier. The control center also operates the crawling auxiliary device of the upper clamp unit to move against the pier, so that when the lifting drive device drives the upper clamp unit to move upward, the crawling auxiliary wheel rolls on the pier.

[0014] Preferably, an upper pad is provided below the upper clamp unit, a lower pad corresponding to the upper pad is provided on the lower clamp unit, and a support foot is provided below the lower clamp unit.

[0015] Preferably, a load-bearing support platform is provided on the lifting and crawling device. The support platform includes several platform units set on the upper clamp unit.

[0018] The beneficial effects of this invention are as follows: This invention enables angle adjustment between adjacent upper or lower clamp units through a rotation control device consisting of a rotating motor and a hinged seat. When facing piers of different shapes and inclination angles, this invention can flexibly adapt to ensure that the clamp units fit tightly against the pier surface, improve the stability and safety of the entire lifting system, and expand the scope of application of the system.

[0019] The crawling auxiliary wheels in the crawling auxiliary device can roll on the pier column when the lifting drive device drives the upper clamp unit to move upward, reducing friction and making the crawling process smoother. At the same time, the crawling auxiliary support column and the hydraulic crawling drive device can provide stable support force to ensure stability during the crawling process and avoid swaying or tilting.

[0024] The technical solution of the present invention will now be described with reference to the accompanying drawings. However, the described embodiments are only some embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1 to 10 As shown, the present invention provides a cap beam support lifting system, comprising: The lifting and crawling device 11 includes a plurality of lifting and crawling units 101 connected end to end in sequence; The lifting and crawling unit 101 includes an upper clamp unit 111 and a lower clamp unit 112. An angle control device 104 is provided between adjacent upper clamp units 111 or lower clamp units 112. A lifting drive device 113 is connected between the upper clamp unit 111 and the lower clamp unit 112 to drive the upper clamp unit 111 and the lower clamp unit 112 to move up and down. Several upper clamp units 111 are connected by a corner control device 104 to form an upper clamp assembly 102, and several lower clamp units 112 are connected by a corner control device 104 to form a lower clamp assembly 103. Both the upper clamp assembly 102 and the lower clamp assembly 103 are equipped with clamp locking devices 105 and crawling auxiliary devices 106.

[0026] Specifically, the lifting and crawling device 11 consists of several lifting and crawling units 101 connected end to end. Each lifting and crawling unit 101 includes an upper clamping unit 111 and a lower clamping unit 112, which are connected by a lifting drive device 113 to achieve relative vertical movement. An angle control device 104 is provided between adjacent upper clamping units 111 or lower clamping units 112 to adjust the angle between the units to adapt to piers 14 of different shapes.

[0027] The lifting and crawling unit 101 is the core actuator of the entire lifting system. Through the alternating tightening and loosening of the upper and lower clamping units 112 and under the action of the lifting drive device 113, the entire device can climb or descend on the pier 14. The angle control device 104 gives the system the ability to adapt to the complex shape of the pier 14, improving the versatility of the system.

[0028] The combined use of multiple lifting and crawling units 101 can distribute the load and enhance the load-bearing capacity of the system. At the same time, by precisely controlling the movement of each unit, a smooth and reliable lifting process can be achieved.

[0029] Specifically, the lifting drive device 113 can employ common linear drive components such as hydraulic cylinders or electric push rods, with its two ends connected to the upper clamp unit 111 and the lower clamp unit 112, respectively. Through telescopic movement, the upper clamp unit 111 and the lower clamp unit 112 are driven to move relative to each other, realizing the climbing or lowering of the entire lifting crawling unit 101 on the pier column 14. Hydraulic cylinders or electric push rods have large driving force and precise control performance, which can meet the load and accuracy requirements during the lifting of the cap beam support. By reasonably selecting the specifications and parameters of the drive components, the system can be ensured to operate stably under different working conditions.

[0030] like Figures 1 to 3 ,and Figures 8 to 10 As shown, in this embodiment, the number of lifting crawling units 101 in the cap beam support lifting system is set to eight, which can better adapt to both circular and square piers 14. In other embodiments (not shown in the figure), the number of lifting crawling units in the cap beam support lifting system can be four, five, seven, nine, or any other desired number to suit the application scenario.

[0031] like Figures 4 to 6 As shown, in this embodiment, the corner control device 104 includes a rotating motor 141 and a hinge seat 142 connected to the rotating motor 141. The hinge seat 142 is provided with a hinge protrusion 143. The upper clamp unit 111 includes an upper corner end 121 and an upper connecting end 122. The upper corner end 121 is fixedly connected to the corner control device 104, and the upper connecting end 122 is provided with a first hinge hole 123 corresponding to the hinge protrusion 143. The lower clamp unit 112 includes a lower corner end 131 and a lower connecting end 132. The lower corner end 131 is fixedly connected to the corner control device 104, and the lower connecting end 132 is provided with a second hinge hole 133 corresponding to the hinge protrusion 143. The upper clamp unit 111 and the lower clamp unit 112 are both provided with a receiving groove 124. A clamp workbench 125 is provided in the receiving groove 124. A fixing column 126 is provided on the clamp workbench 125 to fix and connect the upper clamp unit 111 or the lower clamp unit 112.

[0032] Specifically, the upper clamp unit 111 includes an upper corner end 121 and an upper connecting end 122. The upper corner end 121 is fixedly connected to the corner control device 104, and the upper connecting end 122 is provided with a first hinge hole 123 corresponding to the hinge protrusion 143, for connecting with the adjacent upper clamp unit 111 through the corner control device 104. The upper clamp unit 111 is also provided with a receiving groove 124, in which a clamp worktable 125 is provided. The clamp worktable 125 is provided with a fixing post 126 fixedly connected to the upper clamp unit 111, for installing the clamp locking device 105 and the crawling auxiliary device 106.

[0033] The lower clamp unit 112 has a similar structure to the upper clamp unit 111, including a lower corner end 131 and a lower connecting end 132. The lower corner end 131 is fixedly connected to the corner control device 104, and the lower connecting end 132 is provided with a second hinge hole 133 corresponding to the hinge protrusion 143, for connecting with the adjacent lower clamp unit 112 through the corner control device 104. It also includes a receiving groove 124, a clamp worktable 125, and a fixing column 126 for installing related devices.

[0034] The upper and lower clamp units 112 are tightly connected to the pier column 14 via clamp locking devices 105, providing a stable support point for the entire lifting and crawling device 11. During lifting, the device alternately clamps and releases the pier column 14, coordinating with the lifting drive device 113 to achieve climbing or descending movements. Simultaneously, the crawling auxiliary device 106 of the upper clamp unit 111 provides auxiliary support and guidance during lifting, ensuring stable movement of the device along the pier column 14. The upper and lower clamp units 112 can reliably connect to the pier column 14 and withstand significant loads. The design of the receiving slot 124 and the clamp worktable 125 provides installation space for other devices, resulting in a compact and rationally laid-out system.

[0035] like Figures 4 to 6As shown, in this embodiment, the clamp locking device 105 and the crawling auxiliary device 106 are arranged in the clamp workbench 125. The clamp locking device 105 includes a clamp support column 151 and a hydraulic clamp drive device for driving the clamp support column 151 to extend and retract. The crawling auxiliary device 106 includes a crawling auxiliary column 161 and a hydraulic crawling drive device for driving the crawling auxiliary column 161 to extend and retract. Among them, a clamp buffer pad is provided at one end of the clamp support 151, and a crawling auxiliary wheel 163 is provided at one end of the crawling auxiliary support 161.

[0036] Specifically, the clamp locking device 105 is installed in the clamp working table 125, including the clamp support 151 and a hydraulic clamp drive device for driving the clamp support 151 to extend and retract. A clamp buffer pad is provided at one end of the clamp support 151 to reduce the impact force on the pier column 14 when clamping.

[0037] The hydraulic clamp drive unit extends the clamp support 151, causing the clamp buffer pad to fit tightly against the surface of the pier 14. Through friction, the upper clamp unit 111 or the lower clamp unit 112 is securely fixed to the pier 14, providing stable support for the lifting and crawling device 11. When release is needed, the clamp support 151 retracts, releasing the clamp on the pier 14.

[0038] The design of the clamp buffer pad effectively protects the surface of pier 14, preventing damage caused by excessive clamp force. The hydraulic drive provides stable and reliable clamp force, ensuring safety during the lifting process.

[0039] Specifically, the crawling auxiliary device 106 is also installed in the clamping workbench 125, including a crawling auxiliary support column 161 and a hydraulic crawling drive device for driving the extension and retraction of the crawling auxiliary support column 161. A crawling auxiliary wheel 163 is provided at one end of the crawling auxiliary support column 161. The crawling auxiliary wheel 163 can be made of rubber to increase the friction with the surface of the pier column 14.

[0040] During the lifting process, when the upper clamp unit 111 needs to move upward, the hydraulic crawling drive device drives the crawling auxiliary support column 161 to extend, causing the crawling auxiliary wheel 163 to abut against the surface of the pier column 14. Under the action of the lifting drive device 113, the upper clamp unit 111 moves upward, and the crawling auxiliary wheel 163 rolls on the pier column 14, playing a role in auxiliary support and guidance, reducing the friction between the upper clamp unit 111 and the pier column 14, and making the lifting process more stable.

[0041] The rolling friction of the crawling auxiliary wheel 163 greatly reduces resistance during lifting and lowering, thus reducing energy consumption while improving the smoothness and precision of lifting and lowering. The hydraulically driven crawling auxiliary support 161 can precisely control the extension length as needed, adapting to piers 14 of different diameters.

[0042] like Figure 7 As shown, in this embodiment, a rotating rod 144 is connected between the rotating motor 141 and the hinge seat 142. The rotating motor 141 drives the hinge seat 142 to rotate through the rotating rod 144. The rotating rod 144 is provided with a locking device 145. The locking device 145 includes a locking disc 146 fixedly connected to the rotating rod 144 and a braking device 147 for limiting the rotation of the locking disc 146. The braking device 147 includes a brake disc 148 and a brake motor 149 that drives the brake disc 148 to lock the locking disc 146.

[0043] Specifically, the angle control device 104 includes a rotary motor 141, a hinge seat 142 connected to the rotary motor 141, and a hinge protrusion 143 disposed on the hinge seat 142. The rotary motor 141 is connected to the hinge seat 142 via a rotating rod 144, and a locking device 145 is disposed on the rotating rod 144. The locking device 145 includes a locking disc 146 fixedly connected to the rotating rod 144 and a braking device 147 for limiting the rotation of the locking disc 146. The braking device 147 consists of a brake disc 148 and a brake motor 149 that drives the brake disc 148 to lock the locking disc 146.

[0044] The rotating motor 141 drives the hinge seat 142 to rotate via the rotating rod 144, thereby causing the connected upper clamp unit 111 or lower clamp unit 112 to change its angle to adapt to different shapes of pier columns 14. After the angle is adjusted to the correct position, the locking device 145 drives the brake disc 148 via the brake motor 149 to lock the locking disc 146, fixing the position of the rotating rod 144, preventing the hinge seat 142 from rotating accidentally, and ensuring the stability of the angle control.

[0045] The angle control device 104 enables the lifting and crawling device 11 to flexibly handle piers 14 of various complex shapes, improving the system's versatility and adaptability. The locking device 145 ensures stability after angle adjustment, avoiding safety hazards caused by angle changes during lifting.

[0046] In other embodiments (not shown in the figures), the locking disc and braking device can also be configured as any desired structure to achieve the braking function, such as a ratchet and pawl mechanism, an electromagnetic brake, or a hydraulic brake.

[0047] In this embodiment, the cap beam support lifting system also includes a control center. When the lifting crawling device 11 performs the climbing column 14 operation, the control center manipulates the clamp locking device 105 of the lower clamp unit 112 to clamp and lock the column 14, while the clamp locking device 105 of the upper clamp unit 111 moves away from the column 14. The control center also manipulates the crawling auxiliary device 106 of the upper clamp unit 111 to abut against the column 14, so that when the lifting drive device 113 drives the upper clamp unit 111 to move upward, the crawling auxiliary wheel 163 rolls on the column 14. When the lifting and crawling device 11 is performing the downward crawling operation of the pier column 14, the control center operates the clamp locking device 105 of the upper clamp unit 111 to clamp and lock the pier column 14, while the clamp locking device 105 of the lower clamp unit 112 moves away from the pier column 14, and operates the crawling auxiliary device 106 of the lower clamp unit 112 to abut against the pier column 14, so that when the lifting drive device 113 drives the upper clamp unit 111 to move downward, the crawling auxiliary wheel 163 rolls on the pier column 14.

[0048] Specifically, the control center adopts a computer control system, equipped with an operation panel, display screen, and corresponding control software. It connects to the various drive components and sensors in the lifting and crawling device 11 via wired or wireless communication to achieve centralized control and monitoring of the system.

[0049] The control center is the core control component of the entire girder support lifting system, responsible for operating all actions of the lifting crawling device 11. When the lifting crawling device 11 is climbing the pier 14, the control center precisely controls the clamp locking device 105 of the lower clamp unit 112 to clamp and lock the pier 14 according to the preset program and sensor feedback, while the clamp locking device 105 of the upper clamp unit 111 moves away from the pier 14, and operates the crawling auxiliary device 106 of the upper clamp unit 111 to abut against the pier 14. Simultaneously, it controls the lifting drive device 113 to drive the upper clamp unit 111 upwards, achieving the climbing of the device. During descent, the control center operates the various devices in reverse order to ensure a safe and smooth descent. Furthermore, the control center can monitor the system's operating status in real time, such as the pressure and displacement parameters of each drive component. If any abnormality is detected, it will promptly issue an alarm and take corresponding protective measures.

[0050] The application of a computer control system has automated and intelligentized the entire lifting process, improving operational accuracy and safety. Real-time monitoring and feedback control enable timely detection and resolution of potential problems, ensuring stable system operation under various working conditions and significantly improving construction efficiency and quality.

[0051] like Figures 4 to 6 As shown, in this embodiment, an upper pad 127 is provided below the upper clamp unit 111, a lower pad 134 corresponding to the upper pad 127 is provided on the lower clamp unit 112, and a support foot 135 is provided below the lower clamp unit 112.

[0052] Specifically, an upper pad 127 is provided below the upper clamp unit 111, a lower pad 134 corresponding to the upper pad 127 is provided on the lower clamp unit 112, and a support foot 135 is provided below the lower clamp unit 112. The upper pad 127 and the lower pad 134 can be made of elastic materials such as rubber or plastic, and the support foot 135 can be made of steel, possessing sufficient strength and stability.

[0053] The upper foot 127 and the lower foot 134 act as a buffer when the upper and lower clamping units 112 are closed. The support foot 135 provides an additional support point for the entire lifting and crawling device 11 when the lower clamping unit 112 clamps the pier column 14, thereby enhancing the stability of the system. Especially when subjected to large loads, it can effectively disperse stress and prevent the device from deforming.

[0054] The upper foot 127 and lower foot 134 can be made of elastic or plastic material, which can effectively absorb vibration and impact, protect the internal parts of the device, and extend its service life. The support foot 135 improves the stability of the system under complex working conditions and ensures construction safety.

[0055] For example, 3 to Figure 4 As shown, in this embodiment, a load-bearing support platform 13 is provided on the lifting and crawling device 11. The support platform 13 includes a plurality of platform units 171 provided on the upper clamp unit 111. The adjacent platform units 171 are hinged to each other and a platform corner assembly 172 is provided. Among them, a diagonal bracing rod 173 is provided between the platform unit 171 and the upper clamp unit 111.

[0056] Specifically, the support platform 13 is mounted on the lifting and crawling device 11 to bear the load during the construction of the cap beam. The support platform 13 includes several platform units 171 mounted on the upper clamp unit 111. Adjacent platform units 171 are hinged together and equipped with platform corner components 172. The platform units 171 can be welded from steel and possess sufficient strength and rigidity. Diagonal bracing rods 173 are provided between the platform units 171 and the upper clamp unit 111 to enhance the stability of the platform.

[0057] The support platform 13 provides a stable working plane for the cap beam construction, allowing construction personnel and equipment to operate on the platform. The hinges between platform units 171 and the platform corner assembly 172 enable the support platform 13 to adapt to the angle changes of the lifting and crawling device 11, ensuring that the support platform 13 is suitable for the lifting and crawling device 11. The diagonal bracing rods 173 further enhance the platform's load-bearing capacity and resistance to deformation.

[0058] The support platform 13 can withstand large loads, meeting the requirements of the cap beam construction. The design of the hinge and platform corner assembly 172 ensures the flexibility and stability of the support platform 13, improving construction efficiency and safety.

[0059] like Figure 4 As shown, in this embodiment, the platform corner assembly 172 includes a corner locking rod 181 rotatably disposed at one end of the platform unit 171, and a corner locking seat 182 for receiving the corner locking rod 181 is disposed at the other end of the platform unit 171. The corner locking seat 182 is rotatably connected to the platform unit 171. A corner locking hole 183 corresponding to the corner locking rod 181 is provided in the corner locking seat 182, and a corner locking bolt 184 for locking the corner locking rod 181 is passed through the corner locking hole 183.

[0060] When the angle between adjacent platform units 171 needs to be adjusted, loosen the angle locking bolt 184 and rotate the angle locking seat 182 to allow the platform units 171 to rotate relative to each other to accommodate the angle changes of the lifting crawling device 11. After adjustment, tighten the angle locking bolt 184 to fix the angle locking rod 181 in the angle locking hole 183, locking the angle between the platform units 171 and ensuring the stability of the support platform 13. The platform angle assembly 172 is simple and reliable in design, easy to operate, and can quickly and accurately adjust the angle between the platform units 171, ensuring that the support platform 13 can provide a stable working plane under different working conditions.

[0061] like Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, in this embodiment, an operating platform 15 is provided on the support platform 13. The operating platform is used to install the construction clamp 16, and the construction platform 17 is erected on the construction clamp 16.

[0062] The overall workflow of the girder support lifting system is as follows: During the construction of the cap beam, the lifting and crawling device is first transported to the vicinity of the pier, and then installed onto the pier using hoisting equipment. During installation, ensure that the upper and lower clamping units are accurately fitted onto the pier, and adjust the angle control device to allow the lifting and crawling device to adapt to the shape and angle of the pier. After installation, operate the clamp locking device of the lower clamping unit via the control center to clamp and lock it onto the pier, firmly fixing the lower clamping unit to the pier. Simultaneously, operate the clamp locking device of the upper clamping unit away from the pier, and operate the crawling auxiliary device of the upper clamping unit to press against the pier, ensuring close contact between the crawling auxiliary wheels and the pier surface.

[0063] Then, the lifting drive device is activated, which drives the upper clamp unit upward. During the ascent, the crawling auxiliary wheels roll on the pier, providing auxiliary support and guidance for the upper clamp unit's rise, ensuring a smooth and accurate ascent. Once the upper clamp unit reaches the designated position, the clamp locking device of the upper clamp unit is operated to lock it onto the pier. Simultaneously, the clamp locking device of the lower clamp unit is operated to move away from the pier, and the lifting drive device then drives the lower clamp unit upward. This cycle is repeated to achieve the gradual ascent of the lifting crawling device on the pier.

[0064] After the lifting and crawling device reaches a suitable height, an operating platform is erected on the support platform, and construction clamps and a construction platform are installed through the operating platform. Construction workers can then perform tasks such as reinforcing bar tying, formwork installation, and concrete pouring on the construction platform. During construction, the height and position of the lifting and crawling device are adjusted via the control center according to the construction progress and needs, providing optimal working conditions for the workers.

[0065] This invention has many applications, including but not limited to the following described scenarios: In bridge construction, the cap beam is a crucial supporting component of the bridge superstructure. This cap beam support lifting system can be used for cap beam construction on various bridge types, such as simply supported beam bridges and continuous beam bridges. Through lifting and crawling functions, it raises the construction platform and formwork to the designed height of the cap beam, providing a stable working platform for construction processes such as concrete pouring, ensuring the construction quality and safety of the cap beam.

[0066] For the construction of high piers (such as those in highway and railway bridges), traditional scaffolding methods are not only costly and time-consuming, but also pose safety risks. This lifting system can gradually ascend along the pier, providing a continuous working platform for construction workers. This avoids the tedious work of frequently setting up and dismantling scaffolding, greatly improving construction efficiency while reducing construction costs and safety risks.

[0067] When encountering irregularly shaped piers (such as inclined piers, curved piers, etc.), ordinary construction equipment is difficult to adapt to their special shapes. The corner control device and platform corner assembly in this technical solution enable the system to flexibly adjust the angle and closely fit the surface of the irregularly shaped pier, providing reliable support and a working platform for the construction of irregularly shaped piers, and meeting the needs of special bridge structure construction.

[0068] In the maintenance and reinforcement of bridges and other structures, high-altitude operations are often required for specific areas. This girder support lifting system can quickly and safely lift maintenance personnel and equipment to the location where repair or reinforcement is needed, providing convenient working conditions and improving maintenance efficiency and quality.
