Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bent cap construction, in particular to a bent cap support lifting system. BACKGROUND

[0002] In the field of bridge construction, bent cap construction is a key link, and its construction efficiency and safety are of great concern. The bent cap support lifting system, as the core equipment to ensure the smooth development of bent cap construction, directly determines the quality, progress and safety of the entire bridge project.

[0003] However, as bridge engineering continues to develop in the direction of complexity and large-scale, more stringent requirements are placed on the bent cap support lifting system. Currently, the shortcomings of adaptability and climbing stability of some bent cap support lifting systems on the market have gradually become a key factor restricting the high-quality development of bridge construction.

[0004] When facing different shapes and sizes of pier columns and complex and variable construction environments, the existing bent cap support lifting system has poor adaptability. For example, the patent CN116201021A discloses a movable bent cap support structure, which adopts a fixed support frame design and is only suitable for pier columns of specific size and shape. When encountering irregular structures such as inclined pier columns and curved pier columns, the support cannot closely fit the surface of the pier column, resulting in a significant reduction in installation stability and making it difficult to provide reliable support, severely limiting its application range.

[0005] The stability during climbing is an important indicator of the performance of the bent cap support lifting system. However, some existing systems have obvious defects in climbing stability. For example, the patent CN111648238A discloses a climbing device, which lacks effective auxiliary support and buffering mechanisms during climbing. In actual use, especially when facing large loads or complex geological conditions, it is prone to shaking, jamming and other phenomena. This unstable climbing state not only affects construction efficiency, but also increases safety risks, posing a potential threat to construction personnel and equipment.

[0006] Therefore, a new bent cap support lifting system is needed, which can significantly expand the adaptability of the system, allowing it to flexibly respond to various shapes and sizes of pier columns and complex and variable construction environments; and effectively reduces the shaking and jamming phenomena during climbing, ensuring smooth climbing even under large loads or complex geological conditions, greatly improving the overall stability of the system, providing a high-performance and high-reliability lifting system for bent cap construction, and helping to promote the development of the bridge construction industry towards higher quality and higher efficiency.

[0042] 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.

[0043] like Figures 1 to 10 As shown, the present invention provides a cap beam support lifting system, comprising:

[0044] The lifting and crawling device 11 includes a plurality of lifting and crawling units 101 connected end to end in sequence;

[0045] 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.

[0046] 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.

[0047] Specifically, the lifting and crawling device 11 is composed of a plurality of lifting and crawling units 101 connected in sequence. Each lifting and crawling unit 101 comprises an upper hoop unit 111 and a lower hoop unit 112, which are connected by a lifting driving device 113 to realize relative movement up and down. A corner control device 104 is arranged between adjacent upper hoop units 111 or lower hoop units 112 to adjust the angle between the units to adapt to different shapes of the pier 14.

[0048] The lifting and crawling unit 101 is the core executive component of the entire lifting system, which realizes the climbing or descending of the entire device on the pier 14 by alternately tightening and loosening the pier 14 by the upper and lower hoop units 112 and under the action of the lifting driving device 113. The corner control device 104 gives the system the ability to adapt to complex pier 14 shapes, improving the versatility of the system.

[0049] The combination of multiple lifting and crawling units 101 can disperse the load and enhance the carrying capacity of the system, while precise control of the action of each unit can realize a smooth and reliable lifting process.

[0050] Specifically, the lifting driving device 113 can use common linear driving elements such as hydraulic cylinders or electric push rods, with both ends connected to the upper hoop unit 111 and the lower hoop unit 112. By telescopic action, the upper hoop unit 111 and the lower hoop unit 112 are driven to move relative to each other, realizing the climbing or descending of the entire lifting and crawling unit 101 on the pier 14. The hydraulic cylinder or electric push rod has a large driving force and precise control performance, which can meet the requirements of load and precision in the lifting process of the bent cap support. By reasonably selecting the specifications and parameters of the driving elements, the system can be ensured to operate stably under different working conditions.

[0051] As shown in Figures 1 to 3 , and Figures 8 to 10 In this embodiment, the number of lifting and crawling units 101 in the bent cap support lifting system is set to eight, which can better adapt to round piers 14 and square piers 14. In other embodiments (not shown in the figure), the number of lifting and crawling units in the bent cap support lifting system can be set to four, five, seven, nine, and any desired number to adapt to the use scenario.

[0052] As shown in Figures 4 to 6 , in this embodiment, the corner control device 104 includes a rotating motor 141 and a hinged seat 142 connected to the rotating motor 141, and the hinged seat 142 is provided with a hinged protrusion 143;

[0053] The upper clamping unit 111 comprises an upper corner end 121 and an upper connecting end 122. The upper corner end 121 is fixedly connected with the corner control device 104, and the upper connecting end 122 is provided with a first hinged hole 123 corresponding to the hinged protrusion 143, for being connected with the adjacent upper clamping unit 111 through the corner control device 104.

[0054] The lower clamping unit 112 comprises a lower corner end 131 and a lower connecting end 132. The lower corner end 131 is fixedly connected with the corner control device 104, and the lower connecting end 132 is provided with a second hinged hole 133 corresponding to the hinged protrusion 143, for being connected with the adjacent lower clamping unit 112 through the corner control device 104.

[0055] The upper clamping unit 111 and the lower clamping unit 112 are both provided with a receiving groove 124, in which a clamping workbench 125 is arranged. The clamping workbench 125 is provided with a fixing column 126 for fixedly connecting the upper clamping unit 111 or the lower clamping unit 112.

[0056] Specifically, the upper clamping unit 111 comprises an upper corner end 121 and an upper connecting end 122. The upper corner end 121 is fixedly connected with the corner control device 104, and the upper connecting end 122 is provided with a first hinged hole 123 corresponding to the hinged protrusion 143, for being connected with the adjacent upper clamping unit 111 through the corner control device 104. The upper clamping unit 111 is also provided with a receiving groove 124, in which a clamping workbench 125 is arranged. The clamping workbench 125 is provided with a fixing column 126 for fixedly connecting the upper clamping unit 111, for installing the clamping locking device 105 and the crawling auxiliary device 106.

[0057] The lower clamping unit 112 has a similar structure to the upper clamping unit 111, comprising a lower corner end 131 and a lower connecting end 132. The lower corner end 131 is fixedly connected with the corner control device 104, and the lower connecting end 132 is provided with a second hinged hole 133 corresponding to the hinged protrusion 143, for being connected with the adjacent lower clamping unit 112 through the corner control device 104. Similarly, a receiving groove 124, a clamping workbench 125 and a fixing column 126 are provided for installing relevant devices.

[0058] The upper and lower clamping units 112 are tightly connected with the pier column 14 through the clamping locking device 105, providing a stable support point for the entire lifting and crawling device 11. During the lifting process, the pier column 14 is alternately clamped and released, and the lifting and descending actions are realized in cooperation with the lifting driving device 113. At the same time, the crawling auxiliary device 106 of the upper clamping unit 111 plays a supporting and guiding role during the lifting process, ensuring the stable movement of the device along the pier column 14. The upper and lower clamping units 112 can be reliably connected with the pier column 14 and can bear a large load. The design of the receiving groove 124 and the clamping workbench 125 provides installation space for other devices, making the entire system structure compact and layout reasonable.

[0059] As Figures 4 to 6As shown, in this embodiment, the hoop locking device 105 and the crawling auxiliary device 106 are arranged in the hoop workbench 125. The hoop locking device 105 includes a hoop support 151 and a hydraulic hoop driving device for driving the hoop support 151 to extend and retract. The crawling auxiliary device 106 includes a crawling auxiliary support 161 and a hydraulic crawling driving device for driving the crawling auxiliary support 161 to extend and retract.

[0060] In the embodiment, a hoop buffer pad is arranged at one end of the hoop support 151, and a crawling auxiliary wheel 163 is arranged at one end of the crawling auxiliary support 161.

[0061] Specifically, the hoop locking device 105 is arranged in the hoop workbench 125 and includes the hoop support 151 and the hydraulic hoop driving device for driving the hoop support 151 to extend and retract. A hoop buffer pad is arranged at one end of the hoop support 151 to reduce the impact force on the pier column 14 during the hoop operation.

[0062] The hydraulic hoop driving device drives the hoop support 151 to extend, so that the hoop buffer pad closely abuts against the surface of the pier column 14, and the upper hoop unit 111 or the lower hoop unit 112 is firmly fixed on the pier column 14 by the friction force, thereby providing stable support for the lifting and crawling device 11. When it is necessary to loosen, the hoop support 151 is driven to retract, thereby releasing the hoop on the pier column 14.

[0063] The design of the hoop buffer pad effectively protects the surface of the pier column 14 and avoids damage caused by excessive hoop force. The hydraulic driving mode provides stable and reliable hoop force, thereby ensuring the safety during the lifting process.

[0064] Specifically, the crawling auxiliary device 106 is also arranged in the hoop workbench 125 and includes the crawling auxiliary support 161 and the hydraulic crawling driving device for driving the crawling auxiliary support 161 to extend and retract. The crawling auxiliary wheel 163 is arranged at one end of the crawling auxiliary support 161, and the crawling auxiliary wheel 163 can be made of rubber to increase the friction force with the surface of the pier column 14.

[0065] During the lifting process, when the upper hoop unit 111 needs to move upward, the hydraulic crawling driving device drives the crawling auxiliary support 161 to extend, so that the crawling auxiliary wheel 163 abuts against the surface of the pier column 14. Under the action of the lifting driving device 113, the upper hoop unit 111 moves upward, and the crawling auxiliary wheel 163 rolls on the pier column 14, thereby playing a role in auxiliary support and guidance and reducing the friction force between the upper hoop unit 111 and the pier column 14, so that the lifting process is more stable.

[0066] The rolling friction mode of the crawling auxiliary wheel 163 greatly reduces the resistance during the lifting process, reduces the energy consumption, and improves the stability and precision of the lifting. The hydraulic driving crawling auxiliary support 161 can accurately control the extension length according to the needs and adapt to pier columns 14 with different diameters.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] In this embodiment, the bent cap support lifting system also includes a control center. When the lifting climbing device 11 is climbing the pier column 14, the control center controls the lower hoop unit 112 to lock the pier column 14 with the hoop locking device 105, controls the upper hoop unit 111 to move away from the pier column 14 with the hoop locking device 105, and controls the climbing auxiliary device 106 of the upper hoop unit 111 to abut against the pier column 14, so that when the lifting driving device 113 drives the upper hoop unit 111 to move upward, the climbing auxiliary wheel 163 rolls on the pier column 14.

[0073] When the lifting climbing device 11 is climbing the pier column 14, the control center controls the lower hoop unit 112 to lock the pier column 14 with the hoop locking device 105, controls the upper hoop unit 111 to move away from the pier column 14 with the hoop locking device 105, and controls the climbing auxiliary device 106 of the upper hoop unit 111 to abut against the pier column 14, so that when the lifting driving device 113 drives the upper hoop unit 111 to move upward, the climbing auxiliary wheel 163 rolls on the pier column 14.

[0074] Specifically, the control center adopts a computer control system equipped with an operation panel, a display screen and corresponding control software. Through wired or wireless communication, it is connected with each driving element and sensor in the lifting climbing device 11, realizing centralized control and monitoring of the system.

[0075] The control center is the core control component of the entire bent cap support lifting system, responsible for controlling the actions of the lifting climbing device 11. When the lifting climbing device 11 is climbing the pier column 14, the control center accurately controls the lower hoop unit 112 to lock the pier column 14 with the hoop locking device 105, controls the upper hoop unit 111 to move away from the pier column 14 with the hoop locking device 105, and controls the climbing auxiliary device 106 of the upper hoop unit 111 to abut against the pier column 14 according to the preset program and the information fed back by the sensor. At the same time, the lifting driving device 113 is controlled to drive the upper hoop unit 111 to move upward, realizing the climbing of the device. In the descending process, the control center operates the devices in the opposite order to ensure the safety and stability of the descending process. In addition, the control center can also monitor the running state of the system in real time, such as the pressure, displacement and other parameters of each driving element. Once an abnormal situation is found, an alarm is sent in time and corresponding protection measures are taken.

[0076] The application of the computer control system makes the entire lifting process automatic and intelligent, improving the accuracy and safety of the operation. Through real-time monitoring and feedback control, potential problems can be found and solved in time, ensuring the stable operation of the system under various working conditions and greatly improving the construction efficiency and quality.

[0077] For example, Figures 4 to 6As shown, in this embodiment, an upper pad 127 is arranged below the upper hoop unit 111, a lower pad 134 corresponding to the upper pad 127 is arranged on the lower hoop unit 112, and a support leg 135 is arranged below the lower hoop unit 112.

[0078] Specifically, an upper pad 127 is arranged below the upper hoop unit 111, a lower pad 134 corresponding to the upper pad 127 is arranged on the lower hoop unit 112, and a support leg 135 is arranged below the lower hoop 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 leg 135 can be made of steel, which has sufficient strength and stability.

[0079] The upper pad 127 and the lower pad 134 play a buffering role when the upper and lower hoop units 112 are closed, and the support leg 135 provides an additional support point for the entire lifting and crawling device 11 when the lower hoop unit 112 tightly embraces the pier 14, thereby enhancing the stability of the system, effectively dispersing stress and preventing deformation of the device, especially when bearing a large load.

[0080] The upper pad 127 and the lower pad 134 can be made of elastic or plastic materials, which can effectively absorb vibration and impact, protect internal parts of the device, and prolong the service life. The arrangement of the support leg 135 improves the stability of the system under complex working conditions and ensures construction safety.

[0081] As shown in FIGS. 3 to Figure 4 As shown, in this embodiment, a support platform 13 for bearing load is arranged on the lifting and crawling device 11, the support platform 13 includes a plurality of platform units 171 arranged on the upper hoop unit 111, and platform corner assemblies 172 are arranged between adjacent platform units 171 and are hingedly connected to each other.

[0082] Among them, diagonal bracing rods 173 are arranged between the platform units 171 and the upper hoop unit 111.

[0083] Specifically, the support platform 13 is arranged on the lifting and crawling device 11 and is used to bear the load during the construction of the cap beam. The support platform 13 includes a plurality of platform units 171 arranged on the upper hoop unit 111, and platform corner assemblies 172 are arranged between adjacent platform units 171 and are hingedly connected to each other. The platform units 171 can be made of steel and have sufficient strength and rigidity. Diagonal bracing rods 173 are arranged between the platform units 171 and the upper hoop unit 111 to enhance the stability of the platform.

[0084] The support platform 13 provides a stable working plane for the construction of the bent cap, and the construction personnel and equipment can operate on the platform. The hinges between the platform units 171 and the platform corner assembly 172 enable the support platform 13 to adapt to the angle changes of the climbing lifting device 11, ensuring that the support platform 13 can be applied to the climbing lifting device 11. The inclined bracing rods 173 further enhance the load-bearing capacity and deformation resistance of the platform.

[0085] The support platform 13 can withstand large loads and meet the requirements of bent cap construction. The design of the hinges and the platform corner assembly 172 ensures the flexibility and stability of the support platform 13, improving construction efficiency and safety.

[0086] As shown in Figure 4 , in this embodiment, the platform corner assembly 172 includes a corner locking rod 181 rotatably arranged at one end of the platform unit 171, and a corner locking seat 182 receiving the corner locking rod 181 is arranged at the other end of the platform unit 171.

[0087] The corner locking seat 182 is rotatably connected to the platform unit 171, and a corner locking hole 183 corresponding to the corner locking rod 181 is formed in the corner locking seat 182, and a corner locking bolt 184 for locking the corner locking rod 181 is arranged in the corner locking hole 183.

[0088] When the angle between adjacent platform units 171 needs to be adjusted, the corner locking bolt 184 is loosened, and the corner locking seat 182 is rotated to enable the platform units 171 to rotate relative to each other to adapt to the angle changes of the climbing lifting device 11. After adjustment, the corner locking bolt 184 is tightened to fix the corner locking rod 181 in the corner locking hole 183, locking the angle between the platform units 171 and ensuring the stability of the support platform 13. The design of the platform corner assembly 172 is simple and reliable, 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.

[0089] As shown in Figure 1 , Figure 2 , Figure 8 and Figure 9 , in this embodiment, an operation platform 15 is arranged on the support platform 13, and the operation platform is used to install a construction hoop 16, and the construction platform 17 is arranged on the construction hoop 16.

[0090] The overall working process of the bent cap support lifting system is as follows:

[0091] During the construction of the bent cap, the lifting and crawling device is first transported to the vicinity of the pier column and installed on the pier column by hoisting equipment. During installation, the upper and lower hoop units are accurately fitted on the pier column, and the angle control device is adjusted so that the lifting and crawling device can adapt to the shape and angle of the pier column. After installation is complete, the hoop locking device of the lower hoop unit is controlled by the control center to lock the pier column, so that the lower hoop unit is firmly fixed on the pier column. At the same time, the hoop locking device of the upper hoop unit is controlled to move away from the pier column, and the crawling auxiliary device of the upper hoop unit is controlled to abut against the pier column, so that the crawling auxiliary wheel is in close contact with the surface of the pier column.

[0092] Then, the lifting drive device is started, and the lifting drive device drives the upper hoop unit to move upward. During the upward movement, the crawling auxiliary wheel rolls on the pier column, providing auxiliary support and guiding for the upward movement of the upper hoop unit, ensuring that the upper hoop unit can move upward smoothly and accurately. When the upper hoop unit reaches the designated position, the hoop locking device of the upper hoop unit is controlled to lock the pier column, and the hoop locking device of the lower hoop unit is controlled to move away from the pier column. Then, the lower hoop unit is driven upward by the lifting drive device, and the process is repeated to gradually climb the pier column.

[0093] After the lifting and crawling device climbs to the appropriate height, an operation platform is built on the support platform, and a construction hoop and a construction platform are installed on the operation platform. Construction personnel can perform steel binding, formwork installation, and concrete pouring operations on the construction platform during construction. During construction, the height and position of the lifting and crawling device are adjusted by the control center according to the construction progress and needs to provide the best construction conditions for the construction personnel.

[0094] The present application has many use scenarios, including but not limited to the following described scenarios:

[0095] In bridge construction, the bent cap is an important supporting component of the superstructure of the bridge. The bent cap support lifting system can be used for the construction of bent caps of different types of bridges, such as simply supported beam bridges, continuous beam bridges, etc. Through the lifting and crawling functions, the construction platform and formwork are lifted to the design height of the bent cap to provide a stable working platform for the concrete pouring and other construction processes, ensuring the construction quality and safety of the bent cap.

[0096] For the construction of high pier columns (such as high pier columns in highway and railway bridges), the traditional scaffolding construction method not only has high cost and long construction period, but also has poor safety. The lifting system can gradually climb along the pier column to provide a continuous working platform for the construction personnel, avoiding the tedious work of frequently setting up and dismantling scaffolding, greatly improving the construction efficiency, and reducing the construction cost and safety risk.

[0097] When encountering special-shaped pier columns (such as inclined pier columns, curved pier columns, etc.), ordinary construction equipment is difficult to adapt to their special shapes. The corner control device and platform corner assembly in the technical scheme can flexibly adjust the angle of the system, closely fit the surface of the special-shaped pier column, provide reliable support and working platform for the construction of the special-shaped pier column, and meet the needs of special bridge structure construction.

[0098] In the maintenance and reinforcement engineering of buildings such as bridges, high-altitude operation is required for specific parts. The bent cap support lifting system can quickly and safely lift maintenance personnel and equipment to the position requiring maintenance or reinforcement, providing convenient working conditions for maintenance work and improving maintenance efficiency and quality.
