Description

Technical Field

[0001] The present invention relates to the technical field of hanging baskets for bridge construction, and more specifically, to an anti - detachment device and method for a hanging basket in the construction of a continuous rigid - frame bridge. Background Technique

[0002] In the construction of continuous rigid - frame bridges, as a light - type cantilever casting device, the hanging basket is widely used for the successive construction of segmental box girders. The core function of the hanging basket is to provide a support platform for the formwork system, construction loads, and newly poured concrete by hanging at the front end of the already - cast beam segment, and it has the ability to move along the bridge axis.

[0003] The main load - bearing structure of the hanging basket includes a main beam, a front cross - beam, and a rear cross - beam, forming a space truss system, which bears construction loads and transfers them to the already - cast beam body; the formwork system of the hanging basket is suspended below the main beam and is used for concrete shaping, including a bottom form, side forms, and inner forms; the traveling system of the hanging basket consists of guide rails, sliding supports, and driving devices. The guide rails are fixed to the bridge deck or the side of the beam body by high - strength bolts. The sliding supports are located at the rear end of the hanging basket and are slidably connected to the guide rails, providing a guiding and load - bearing path for the movement of the hanging basket; the rear end of the hanging basket is anchored to the already - hardened beam segment through precision - rolled threaded steel or steel strands to ensure construction stability.

[0004] Among them, the connection reliability between the sliding support and the guide rail is the core of the traveling system. The sliding support usually adopts cast steel or welded steel structures, and rollers or sliders are arranged at its bottom, and the rollers or sliders cooperate with the guide rail grooves on the side of the guide rail to facilitate the sliding of the sliding support along the guide rail.

[0005] In actual construction, due to the large span of the bridge and the need for segmented prefabrication and splicing of the guide rails, there are splicing joints between multiple sections of guide rails. The splicing joints are weak links between the sections of guide rails. The closer the sliding support is to the splicing joint, the greater the load pressure on the guide rail. For example, in the construction of a certain cross - river continuous rigid - frame bridge, the hanging basket needs to move multiple times on a long - distance guide rail composed of multiple spliced sections. When the sliding support just stays at the guide - rail splicing joint for construction, the weight at the front end of the hanging basket increases, resulting in an increase in the load at the rear end of the hanging basket. Since at the splicing joint, the ends of adjacent two - section guide rails both bear concentrated upward loads, and due to the small width of the rollers or sliders at the bottom of the sliding support and the short stress - bearing support section at the end of the guide rail, the stress is concentrated on the stress - bearing support section at the end of the guide rail, causing deformation of the stress - bearing support section at the end of the guide rail, and resulting in warping at the connection of the guide rails, which exacerbates the risk of derailment of the rollers or sliders. Summary of the Invention

[0006] An anti - detachment device and method for a hanging basket in the construction of a continuous rigid - frame bridge provided by the present invention aims to solve the following problem: In the prior art, when the sliding support just stays at the guide - rail splicing joint for construction, due to the small width of the rollers or sliders at the bottom of the sliding support and the short stress - bearing support section at the end of the guide rail, the stress is concentrated on the stress - bearing support section at the end of the guide rail.

[0015] In a preferred embodiment, a connecting mechanism is connected between the cleaning mechanism and the moving seat. The connecting mechanism includes a second connecting seat, an adjusting block is rotatably installed on the second connecting seat, a positioning bolt is installed on the second connecting seat, and the positioning bolt is used to position the adjusting block. One end of the adjusting block is connected with a mounting block, a mounting component is installed on the mounting block, and the main seat is installed on the mounting block through the mounting component.

[0016] The present invention also provides a using method of an anti-disengagement device for a continuous rigid frame bridge construction hanging basket, including the following steps:

[0017] S1: Install the sliding support on the guide rail mechanism and lock the sliding support when adjusted to the working position;

[0018] S2: Start the detection component to detect whether there is a splicing joint within a set distance in the middle and at both ends of the sliding support;

[0019] S3: If there is a splicing joint, start the second linear driver on the fixed seat to push the load sharing component to extend in the direction away from the first connecting seat, so as to extend the width of the first connecting seat, and merge the first guide rail and the second guide rail to share the load;

[0025] Through the space reserved between the protruding lateral top block and the side surface of the adapter block and the guide rail groove, the adapter block can be limited laterally, avoiding the continuous vibration and load impact caused by the superposition of concrete pumping and lateral wind loads, which may lead to the adapter block sliding back and forth in the space close to the side of the guide rail groove. This can reduce the frictional loss between the top of the adapter block and the guide rail groove, and solve the problem that the adapter block is not conducive to subsequent movement due to frictional heating and deformation.

[0026] By installing a main seat at one end of the fixed seat and scraping and discharging the concrete slag inside the guide rail groove through a scraper, the concrete slag inside the guide rail groove can be scraped, preventing the accumulation of soil and slag at one end of the installation box from blocking the movement of the adapter block and facilitating the protrusion of the lateral top block.

Detailed implementation manners

[0039] The present application will be further described in detail below with reference to the drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0040] Refer to the attached drawings of the specification Figures 1 to 5 A continuous rigid frame bridge construction hanging basket anti-disconnection device includes a guide rail mechanism 1. A sliding support 2 is installed on the guide rail mechanism 1. The guide rail mechanism 1 includes a first guide rail 11. Both ends of the first guide rail 11 are butt-jointed with a second guide rail 12, and there is a splicing seam between the first guide rail 11 and the second guide rail 12. Guide rail grooves 13 are opened on both sides of the first guide rail 11 and the second guide rail 12. A first connection seat 21 is installed at the position of the sliding support 2 corresponding to the guide rail groove 13, and a load sharing mechanism 4 is installed on the first connection seat 21; the load sharing mechanism 4 includes a fixed seat 41. Detection components are installed on both the first connection seat 21 and the fixed seat 41. A second linear actuator 44 is also installed on the fixed seat 41, and the output end of the second linear actuator 44 is connected to a load sharing component; when the sliding support 2 stops moving on the first guide rail 11, the detection component moves axially along the guide rail groove 13 to detect the splicing seam, so that the second linear actuator 44 pushes the load sharing component to extend in a direction away from the first connection seat 21.

[0041] It should be noted that both the first guide rail 11 and the second guide rail 12 are fixed to the cast beam segment of the bridge by bolts. The cross-sections of the first guide rail 11 and the second guide rail 12 are both in the shape of an I-beam. The sliding components 22 are arranged at both ends of the first connecting seat 21 close to the inner side of the guide rail groove 13. The load-sharing mechanism 4 is provided with at least two groups, which are respectively arranged at both ends of the first connecting seat 21. Attached Figure 3 One group is omitted. The fixed seat 41 is located outside the guide rail groove 13. The fixed seat 41 is a frame member. In order to increase the connection stability, an inclined tie rod can be arranged between the sliding support 2 and the fixed seat 41. The sliding support 2 is equipped with a locking mechanism in the prior art, such as a bolt or a hydraulic lock. The sliding components 22 are installed on one side of the first connecting seat 21 corresponding to the guide rail groove 13.

[0042] In this embodiment, the implementation scenario is specifically as follows: The construction process of the hanging basket mainly includes three stages: installation, movement, and fixation:

[0043] I. Installation stage: Lay multiple sections of the first guide rail 11 and the second guide rail 12 on the top of the cast beam segment of the bridge, and fix the multiple sections of the first guide rail 11 and the second guide rail 12 through flange plates or bolts to form a spliced and continuous guide rail mechanism 1. After the hanging basket and the truss 3 are assembled on the ground or the bridge deck, they are hoisted to the starting end of the guide rail mechanism 1 by a lifting device. The end of the truss 3 where the hanging basket is installed is the front end. The rear end seat 31 of the truss is installed at the rear end of the truss 3. The sliding support 2 is installed on the rear end seat 31 of the truss. The front end seat 32 of the truss is installed at the front end of the truss 3. The sliding components 22 on the sliding support 2 are embedded inside the guide rail groove 13;

[0044] II. Movement stage: Start the driving mechanism, such as a hydraulic jack or a winch, to drive the hanging basket to drive the sliding support 2 to move axially along the guide rail mechanism 1. At this time, the sliding components 22 roll inside the guide rail groove 13. The sliding support 2 advances in sections on the guide rail mechanism 1. The moving distance each time is the length of one segment. After moving the hanging basket to the target position, anchor the rear end of the hanging basket and perform precision calibration to ensure that the load is evenly transmitted to the beam body;

[0045] III. Fixation stage: After the hanging basket is in place, fix the sliding support 2 and the guide rail mechanism 1 through the locking mechanism to prevent accidental displacement of the sliding support 2 on the guide rail mechanism 1 caused by construction vibration or load impact;

[0046] When the sliding support 2 stays at a certain position on the guide rail mechanism 1 and is ready for construction, according to the shutdown signal of the hanging basket drive mechanism, the detection components on the first connecting seat 21 and the fixed seat 41 are started. The detection components move along the axial direction for at least one round trip, and whether there is a splicing seam is detected in the detection route. When the detection component of the first connecting seat 21 detects the splicing seam, the second linear drivers 44 on the two groups of fixed seats 41 are started to push the load sharing component to extend away from the first connecting seat 21, so as to extend the width of the first connecting seat 21, increase the length of the force-bearing support sections of the first guide rail 11 and the second guide rail 12 to disperse the stress, and avoid warping at the connection of the first guide rail 11 and the second guide rail 12; when the sliding support 2 stays on the first guide rail 11 and is close to the splicing seam, the connecting end of the first guide rail 11 alone bears the upward load. At this time, the detection component on the fixed seat 41 close to one end of the second guide rail 12 can detect the splicing seam, and this fixed seat 41 is started to work alone, so that the load sharing component moves towards the second guide rail 12 and completes the lapping, so that the second guide rail 12 shares part of the load of the first guide rail 11; on the contrary, when the sliding support 2 stays on the second guide rail 12 and is close to the splicing seam, the fixed seat 41 close to one end of the first guide rail 11 is started, and the first guide rail 11 is lapped to share part of the load of the first guide rail 11 for the second guide rail 12.

[0047] Further, the detection component includes a first linear driver 42. A detection box 421 is installed at the output end of the first linear driver 42. A concave seat 411 is installed on the fixed seat 41. The first linear driver 42 is fixedly installed inside the concave seat 411. An installation box 43 is installed at one end of the fixed seat 41.

[0048] It should be noted that existing multi-sensor fusion technologies, such as laser + contact probe, are installed inside the detection box 421 to improve the accuracy and real-time performance of splicing seam recognition. A PLC controller of the existing technology is installed inside the installation box 43. The PLC controller controls the work of the first linear driver 42 and the second linear driver 44 respectively. The installation and electrical connection of the PLC controller are common operations for those skilled in the art. The first linear driver 42 drives the detection box 421 to move along the axial direction of the concave seat 411 for at least one round trip.

[0049] Still further, the load sharing component includes a moving seat 441. The second linear driver 44 drives the moving seat 441 to move along the axial direction of the fixed seat 41. An adapter block 442 is installed at one end of the moving seat 441 away from the installation box 43. A load sharing seat 45 is installed at one end of the fixed seat 41 away from the installation box 43. An opening 451 is formed inside the load sharing seat 45. The adapter block 442 penetrates through the opening 451.

[0050] It should be noted that the inner side of the moving seat 441 corresponds to the adapter block 442. The thickness of the adapter block 442 is greater than that of the fixed seat 41. One-third of the adapter block 442 is in sliding contact with the top of the opening 451, and the remaining part is in sliding contact with the top of the guide rail groove 13.

[0051] Furthermore, a limit block 444 is installed at one end of the moving seat 441 away from the adapter block 442, and the limit block 444 is aligned with the load sharing seat 45.

[0052] It should be noted that the limit block 444 is L-shaped. When the moving seat 441 moves to the maximum distance away from the installation box 43, the limit block 444 abuts against one end of the load sharing seat 45, playing a role of limiting and blocking.

[0053] Furthermore, a guiding component 412 is installed on the fixed seat 41. The guiding component 412 includes a guiding column and a guiding cylinder. One end of the guiding column is fixed to the installation box 43, and the guiding cylinder is installed on the outer side of the moving seat 441 away from the adapter block 442.

[0054] It should be noted that when the moving seat 441 moves, it drives the guiding cylinder to slide along the axial direction of the guiding column, playing a guiding role.

[0055] Refer to the attached Figures 4 to 8 In order to facilitate the sliding of the moving seat 441 and the adapter block 442, and reduce the contact friction between the adapter block 442 and the side of the guide rail groove 13, a space of 3 - 5 mm is reserved between the adapter block 442 and the side of the guide rail groove 13. Due to the continuous vibration and load impact caused by the superposition of concrete pumping and lateral wind loads, the adapter block 442 slides back and forth in the space close to the guide rail groove 13, resulting in frictional loss between the top of the adapter block 442 and the guide rail groove 13. In severe cases, the adapter block 442 may be deformed due to frictional heating, which is not conducive to subsequent movement.

[0056] To solve this problem, the following technical solution is also provided: a lateral top block 443 is installed on the adapter block 442, and the lateral top block 443 is slidably arranged on the inner side of the adapter block 442 close to the guide rail groove 13.

[0057] It should be noted that both the length and width of the lateral top block 443 are smaller than those of the adapter block 442.

[0058] Furthermore, a fixing block 4421 is installed inside the adapter block 442. A pushing block 445 is slidably installed on the fixing block 4421. A third linear driver 448 is also fixedly installed on the fixing block 4421, and the output end of the third linear driver 448 is connected to the pushing block 445. The lateral top block 443 is detachably connected to the pushing block 445.

[0059] It should be noted that the third linear driver 448 pushes the push block 445 to move laterally, and the lateral top block 443 can be pushed out from the inside of the adapter block 442.

[0060] Furthermore, an L-shaped groove 446 is formed at one end of the fixed block 4421. The push block 445 is slidably disposed inside the L-shaped groove 446. A protruding block 447 is fixedly provided at one end of the push block 445 close to the third linear driver 448. A limiting port 449 is formed at the position of the fixed block 4421 corresponding to the L-shaped groove 446. A limiting post 4491 is slidably disposed inside the limiting port 449, and the limiting post 4491 is detachably connected to the protruding block 447.

[0061] It should be noted that when the push block 445 advances or retreats along the L-shaped groove 446, the limiting post 4491 slides inside the limiting port 449, playing a guiding role.

[0062] In this embodiment, the implementation scenario is specifically as follows: when the adapter block 442 is stationary after moving and adjusting, the third linear driver 448 pushes the push block 445 forward, thereby driving the lateral top block 443 to extend out from the inside of the adapter block 442. The push block 445 advances along the L-shaped groove 446, and the limiting post 4491 slides inside the limiting port 449, so that the lateral top block 443 cannot completely extend out from the inside of the adapter block 442. Through the space reserved between the extended lateral top block 443 and the side surface of the guide rail groove 13, the adapter block 442 can be limited laterally, avoiding the continuous vibration and load impact caused by the superposition of concrete pumping and lateral wind loads, which may lead to the adapter block 442 sliding back and forth in the space close to the guide rail groove 13, thereby reducing the frictional loss between the top of the adapter block 442 and the guide rail groove 13 and solving the problem that the adapter block 442 is not conducive to subsequent movement due to friction-induced temperature rise and deformation.

[0063] Refer to the attached drawings of the specification Figure 5 、 Figure 9 and Figure 10 , when there is concrete slag inside the guide rail groove 13, as the fixed seat 41 moves, the end of the fixed seat 41 away from the installation box 43 is prone to accumulate muck, which will not only block the movement of the adapter block 442 but also affect the extension of the lateral top block 443.

[0064] To solve this problem, the following technical solution is also provided: a cleaning mechanism 5 is installed at the end of the fixed seat 41 away from the installation box 43. The cleaning mechanism 5 includes a main seat 51, a communication port 52 is formed on the main seat 51, a scraping plate 53 is fixedly provided on one side of the main seat 51, a guiding piece 54 is fixedly provided on the scraping plate 53, a reverse cleaning strip 7 is installed at one end of the fixed seat 41, and a plurality of groups are correspondingly arranged between the reverse cleaning strip 7 and the communication port 52, and the reverse cleaning strip 7 movably penetrates inside the corresponding communication port 52.

[0065] It should be noted that the fixed seat 41 is fixed to the main seat 51 through a connecting shaft. The main seat 51 is arranged in an L shape. The two ends of the guiding piece 54 have different widths. The width of the end close to the scraping plate 53 is greater than that of the other end. The anti-cleaning strip 7 is an elastic strip member, such as a rubber material, and one end of the anti-cleaning strip 7 is always located inside the communication port 52.

[0066] Furthermore, a connecting mechanism 6 is connected between the cleaning mechanism 5 and the moving seat 441. The connecting mechanism 6 includes a second connecting seat 61. An adjusting block 62 is rotatably installed on the second connecting seat 61. A positioning bolt 63 is installed on the second connecting seat 61, and the positioning bolt 63 is used to position the adjusting block 62. One end of the adjusting block 62 is connected with a mounting block 64. A mounting component 65 is installed on the mounting block 64, and the main seat 51 is installed on the mounting block 64 through the mounting component 65.

[0067] It should be noted that the second connecting seat 61 and the adjusting block 62 are rotatably connected. The positioning bolt 63 is a fixing bolt. The mounting component 65 includes a bolt plate, and the main seat 51 is directly positioned by passing a bolt through.

[0068] In this embodiment, the implementation scenario is specifically as follows: By installing the main seat 51 at one end of the fixed seat 41, the concrete slag inside the guide rail groove 13 is scraped off by the scraping plate 53. The concrete slag is scraped to the side of the scraping plate 53 with the guiding piece 54. The concrete slag is discharged from the inside of the guide rail groove 13 through the guidance of the guiding piece 54. By rotating the adjusting block 62, the inclination angle of the mounting block 64 is adjusted, so that the scraping plate 53 is inclined inside the guide rail groove 13. When the fixed seat 41 retracts towards the installation box 43, it drives the main seat 51 to approach the fixed seat 41, so that one end of the anti-cleaning strip 7 extends to the guiding piece 54 to clean the area between adjacent guiding pieces 54. As a whole, the concrete slag inside the guide rail groove 13 can be scraped off, preventing the accumulation of soil at one end of the installation box 43 from blocking the movement of the fitting block 442 and facilitating the extension of the lateral jacking block 443.

[0069] Working principle:

[0070] First, lay multiple sections of the first guide rail 11 and the second guide rail 12 on the top of the already cast beam section of the bridge to form a spliced and continuous guide rail mechanism 1. The sliding components 22 on the sliding supports 2 are embedded inside the guide rail grooves 13.

[0071] Second, start the driving mechanism to drive the hanging basket to drive the sliding support 2 to move axially along the guide rail mechanism 1. At this time, the sliding components 22 roll inside the guide rail grooves 13 to move the hanging basket to the target position.

[0072] Third, after the hanging basket is in place, fix the sliding support 2 to the guide rail mechanism 1 through the locking mechanism to prevent accidental displacement of the sliding support 2 on the guide rail mechanism 1 caused by construction vibration or load impact.

[0073] IV. Start the detection component to detect whether there is a splicing seam in the detection route. When a splicing seam is detected, the second linear driver 44 on the fixed seat 41 pushes the load-sharing component to extend away from the first connecting seat 21, thereby extending the width of the first connecting seat 21.
