Technical Field

[0001] The invention relates to the technical field of bridge construction hanging baskets, and in particular to a hanging basket device for bridge construction. Background Art

[0002] In the field of bridge construction, the cantilever hanging basket casting method is used for segmented construction. The hanging basket system is an aerial construction platform, which is suspended on the cantilever of the truss. First, the casting template is installed, and then the casting construction is carried out. When the construction of this section of the beam is completed, the locking of the hanging basket is released, and a new section of track is laid forward, so that the truss drives the hanging basket to move forward to the next section of the beam, so as to carry out construction section by section.

[0003] After installing the casting formwork and before the casting construction, it is necessary to conduct a pre-stressing test on the installed casting formwork, calculate and record the pre-stressing elastic settlement value of the main truss of the hanging basket. The parameters directly affect the quality of the completed bridge. The existing pre-stressing method adopts the method of stacking weighted sandbags on the hanging basket to achieve the purpose of pre-stressing the hanging basket. Generally, large-scale lifting equipment is used for operation, but due to the existence of the truss, the operating space of the lifting equipment is small; and it is difficult to ensure the uniformity and accuracy of the stacking positions of multiple weighted sandbags, which easily causes uneven force on the hanging basket and affects the accuracy of the pre-stressing test results.

[0004] In view of the emergence of the above problems, the existing technology has not solved them well, which has brought troubles to the normal progress of work in this field. Therefore, there is an urgent need for a hanging basket device for bridge construction to solve the above problems. Summary of the invention

[0009] Optionally, it also includes a winch, a pulley and a board-releasing rope, wherein the winch is arranged on the suspension, the pulley is rotatably arranged on the suspension, and the board-releasing rope passes around the pulley and has its two ends respectively connected to the winch and the free end of the package-releasing board.

[0010] Optionally, it also includes an opening and closing folding plate, which is swingably arranged in the bag dropping opening, and the opening and closing folding plate has a bag holding part and a bag blocking part. After the opening and closing folding plate is swung, it is used to make the bag holding part or the bag blocking part cover the bag dropping opening.

[0011] Optionally, it also includes a conveyor, which is arranged on the suspension, the height of the input end of the conveyor is lower than the height of the output end, and the output end of the conveyor is connected to the package placing board.

[0012] Optionally, it also includes an anchor plate, which is detachably mounted on the bridge body, and has a downward pressing portion, which abuts against the suspension.

[0013] Optionally, it also includes a second winch, a lifting plate and a lifting rope, wherein the second winch is arranged on the truss, and two ends of the lifting rope are respectively connected to the second winch and the lifting plate.

[0014] Optionally, it also includes a travel track, which is detachably arranged on the bridge body, and the truss is slidably arranged on the travel track.

[0015] Optionally, it also includes a support rod and a support plate, wherein the support rod is bolted to the truss, and the support plate is threadedly connected to the support rod for abutting the top surface of the bridge body, and the support plate is located on the front side of the travel track.

[0016] The working principle and beneficial effects of the present invention are: During the bridge construction process, the truss is first installed on the bridge body, the formwork frame is suspended and fixed under the truss by the sling, and then the casting formwork is installed on the formwork frame.

The bagging plate is at a certain angle to the horizontal plane, so that the counterweight placed on the bagging plate can automatically slide down under the action of gravity.

[0017] When it is necessary to conduct a pre-stress test on the casting formwork, workers operate on the main body of the bridge and place the counterweight on the higher end of the bag placing plate.

[0019] First, the hanging basket device used in the bridge construction is designed with an inclined bag-laying plate, so that the counterweight can slide down automatically and can be directly installed on the main body of the bridge without the help of large-scale lifting equipment, which saves construction space and avoids the problem of small operating space for lifting equipment due to the existence of trusses. Secondly, the longitudinal position of the falling counterweight can be accurately controlled through the openable and closable bag-laying mouth to ensure that the counterweight can accurately fall on the required position, thereby improving the accuracy of the preloading test. Furthermore, the sliding of the bag-laying plate can adjust the lateral position of the falling counterweight, so that the counterweight can fall relatively evenly on the casting formwork, avoiding the uneven force of the hanging basket due to uneven stacking position in the traditional method of stacking counterweight sandbags, thereby ensuring the accuracy of the preloading test results and providing reliable guarantee for the quality of the completed bridge. Finally, the device is simple to operate and easy to implement, and can improve the efficiency and quality of bridge construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0025] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0027] Reference Figure 1 to Figure 12 , which is the first embodiment of the present invention, proposes a hanging basket device for bridge construction, which is used to be installed on the bridge body 1, including a truss 2, a lifting rope 3, a formwork frame 4, a casting formwork 5 and a bag placing plate 6, wherein the truss 2 is arranged on the bridge body 1, and the two ends of the lifting rope 3 are respectively connected to the truss 2 and the formwork frame 4, the casting formwork 5 is arranged on the formwork frame 4, the bag placing plate 6 is slidably arranged relative to the formwork frame 4, the bag placing plate 6 is located above the formwork frame 4, and there is an angle between the bag placing plate 6 and the horizontal plane, the bag placing plate 6 is used to transport counterweights, and the bag placing plate 6 has a plurality of openable and closable bag dropping openings 7 for dropping the counterweights.

[0028] In this embodiment, during the bridge construction process, the truss 2 is first installed on the bridge body 1, the formwork frame 4 is suspended and fixed below the truss 2 by the suspension rope 3, and then the casting formwork 5 is installed on the formwork frame 4. The bag placing plate 6 is arranged above the formwork frame 4 and can slide relative to the formwork frame 4. The bag placing plate 6 forms a certain angle with the horizontal plane, so that the counterweight placed on the bag placing plate 6 can automatically slide down under the action of gravity.

[0029] When it is necessary to conduct a pre-stress test on the casting formwork 5, the worker operates on the bridge body 1 and places the counterweight on the higher end of the bag placing plate 6. As the bag placing plate 6 tilts, the counterweight begins to slide downward automatically. When the counterweight slides to the predetermined bag dropping mouth 7 position, if the counterweight at this position needs to fall, the bag dropping mouth 7 is opened to allow the counterweight to accurately fall on the casting formwork 5 below. If the counterweight at this position does not need to fall, the bag dropping mouth 7 is kept closed.

[0030] By controlling the sliding of the bag placing plate 6, the lateral position where the counterweight falls can be adjusted. For example, when it is necessary to perform counterweighting in different lateral areas of the casting template 5, the bag placing plate 6 can be slid laterally to the corresponding position, and then the counterweight is controlled to fall from the bag dropping opening 7 in the above manner.

[0031] First, the hanging basket device used in the bridge construction is designed with an inclined bag-laying plate 6, so that the counterweight can slide down automatically and can be directly installed on the bridge body 1 without the help of large-scale lifting equipment, which saves construction space and avoids the problem of small operating space for lifting equipment due to the existence of the truss 2. Secondly, through the openable and closable bag-laying mouth 7, the longitudinal position of the counterweight falling can be accurately controlled to ensure that the counterweight can accurately fall on the required position, thereby improving the accuracy of the preloading test. Furthermore, the sliding of the bag-laying plate 6 can adjust the lateral position of the counterweight falling, so that the counterweight can fall relatively evenly on the casting formwork 5, avoiding the uneven force of the hanging basket due to uneven stacking position in the traditional method of stacking counterweight sandbags, thereby ensuring the accuracy of the preloading test results and providing reliable guarantee for the quality of the bridge. Finally, the device is simple to operate and easy to implement, and can improve the efficiency and quality of bridge construction.

[0032] Furthermore, it includes a base 8, a suspension 9 and a transverse frame 10, wherein the base 8 is arranged on the bridge body 1, the transverse frame 10 is arranged on the base 8 for transverse sliding, the suspension 9 is arranged on the transverse frame 10 for longitudinal sliding, and the package placing plate 6 is swingably arranged on the suspension 9.

[0033] Furthermore, it also includes a rack 11 and a gear 12, wherein the rack 11 is disposed on the suspension 9, and the gear 12 is rotatably disposed on the transverse frame 10, and the gear 12 is meshed with the rack 11 to drive the suspension 9 to slide in the longitudinal direction.

[0034] In this embodiment, during the bridge construction, the base 8 is first installed on the bridge body 1. The transverse frame 10 is slidably arranged on the base 8 in the transverse direction, and the transverse position can be adjusted as needed. The suspension 9 is slidably arranged on the transverse frame 10 in the longitudinal direction, and the package placing plate 6 is swingably arranged on the suspension 9.

[0035] When the preloading test is required, the drive motor is started, and the drive motor drives the gear 12 to rotate, and the gear 12 is meshed with the rack 11, thereby driving the suspension 9 to slide longitudinally on the transverse frame 10, so that the suspension 9 is suspended above the casting template 5. Then the swing angle of the bag placing plate 6 is adjusted to reach the predetermined inclination angle and position, and then the counterweight is placed on the bag placing plate 6. Due to the inclination of the bag placing plate 6, the counterweight automatically slides down.

[0036] During the downward movement of the counterweight, the lateral position of the counterweight can be adjusted by controlling the lateral sliding of the lateral moving frame 10 on the base 8, so that the counterweight can be more evenly distributed on the casting template 5. When the counterweight slides to the appropriate position of the bag drop opening 7, the bag drop opening 7 is opened to allow the counterweight to accurately fall on the casting template 5 below.

[0037] First, through the longitudinal sliding of the suspension 9 on the transverse frame 10 and the swinging of the bag placing plate 6, the position of the bag placing plate 6 can be flexibly adjusted so that it can better adapt to different construction needs. Secondly, the transverse sliding function of the transverse frame 10 on the base 8 allows the lateral position of the falling counterweight to be accurately adjusted, further ensuring the uniformity of the distribution of the counterweight and avoiding the problem of uneven force on the hanging basket. Furthermore, the coordinated driving mode of the gear 12 and the rack 11 makes the sliding of the suspension 9 more convenient, effective and reliable, improving the operability and efficiency of the construction. Finally, the design of the entire device is reasonable and the functions are complete, which can provide more accurate and reliable guarantees for prestressing experiments in bridge construction.

[0038] Furthermore, it also includes a winch 13, a pulley 14 and a board-releasing rope 15, wherein the winch 13 is arranged on the suspension 9, the pulley 14 is rotatably arranged on the suspension 9, and the board-releasing rope 15 passes around the pulley 14 and both ends are respectively connected to the winch 13 and the free end of the package-releasing board 6.

[0039] In this embodiment, during the bridge construction process, the winch 13 is installed on the suspension 9, and the pulley 14 is also rotatably arranged on the suspension 9. The board-laying rope 15 passes around the pulley 14, one end of which is connected to the winch 13, and the other end is connected to the free end of the package board 6.

[0040] When the inclination angle and position of the package board 6 need to be adjusted, the winch 13 is started, and the winch 13 winds or releases the board rope 15, and the inclination angle and position of the package board 6 are adjusted by changing the length of the board rope 15. If the package board 6 needs to be tilted more, the winch 13 releases the board rope 15, and the free end of the package board 6 drops under the action of gravity, and the inclination angle increases. If the angle of the package board 6 needs to be slowed down, the winch 13 winds the board rope 15, and pulls the free end of the package board 6 upward, thereby reducing the inclination angle.

[0041] When conducting the preloading test, the inclination angle and position of the bag placing plate 6 can be flexibly adjusted according to the different conditions of the ballast piece and the casting template 5 to ensure that the ballast piece can accurately fall from the bag dropping port 7 to the appropriate position on the casting template 5.

[0042] First, through the cooperation of the winch 13, the pulley 14 and the board-laying rope 15, the inclination angle and position of the package-laying plate 6 can be easily adjusted to adapt to different construction requirements and counterweight conditions. Secondly, this adjustment method is simple to operate, and can quickly and accurately achieve the required state of the package-laying plate 6, thereby improving construction efficiency. Furthermore, the falling trajectory of the counterweight can be more accurately controlled to ensure that the counterweight can fall evenly and accurately on the casting formwork 5, thereby improving the accuracy and reliability of the preloading test and providing better protection for the quality of bridge construction.

[0043] Furthermore, it also includes an opening and closing folding plate 16, which is swingably arranged in the bag dropping opening 7, and the opening and closing folding plate 16 has a bag holding part 17 and a bag blocking part 18. After the opening and closing folding plate 16 is swung, it is used to make the bag holding part 17 or the bag blocking part 18 cover the bag dropping opening 7.

[0044] In this embodiment, during bridge construction, the opening and closing folding plate 16 is swingably set in the bag dropping mouth 7. The opening and closing folding plate 16 is L-shaped, and has a bag supporting part 17 and a bag blocking part 18. A telescopic cylinder is installed on the bag placing plate 6. The two ends of the telescopic cylinder are respectively hinged to the bag placing plate 6 and the opening and closing folding plate 16, which can drive the opening and closing folding plate 16 to swing.

[0045] When the counterweight needs to fall at a specific bag drop opening 7, the telescopic cylinder is started to control the opening and closing flap 16 to swing to the state where the bag holding part 17 covers the bag drop opening 7. At this time, the bag blocking part 18 is erected above the bag placing plate 6. When the counterweight slides down along the bag placing plate 6, the bag blocking part 18 can stop the sliding counterweight, stop it from moving, and eliminate its inertia. When the counterweight is stationary, the telescopic cylinder is started again to control the opening and closing flap 16 to swing, so that the bag holding part 17 no longer covers the bag drop opening 7, and the counterweight falls from the bag drop opening 7 in a stationary state and accurately falls on the casting template 5 below.

[0046] When the counterweight is not needed to fall at the current bag drop opening 7, the opening and closing flap 16 is also controlled by the telescopic cylinder to swing to the state where the bag blocking portion 18 covers the bag drop opening 7. At this time, the bag blocking portion 18 is not erected on the bag placing plate 6, and the bag supporting portion 17 is also located below the bag placing plate 6, so the counterweight can slide over the bag placing plate 6 normally and continue to slide to other bag drop openings 7.

[0047] First, by designing a swingable opening and closing flap 16 and controlling it with a telescopic cylinder, the counterweight can be effectively dropped in a stationary state, greatly improving the accuracy of the drop position. Secondly, the bag blocking portion 18 can eliminate the inertia of the counterweight, avoid the influence of inertia on the drop position, ensure that the counterweight can accurately fall at the predetermined position, and improve the stability and accuracy of the preloading test. Furthermore, by flexibly controlling the state of the opening and closing flap 16 as needed, the drop position of the counterweight can be conveniently selected, improving the flexibility and operability of the construction.

[0048] Furthermore, it also includes a conveyor 19, which is arranged on the suspension 9, the input end height of the conveyor 19 is lower than the output end height, and the output end of the conveyor 19 is connected to the package placing plate 6.

[0049] In this embodiment, the conveyor 19 is installed on the suspension 9, and the height of the input end of the conveyor 19 is lower than the height of the output end, and is in an inclined state.

[0050] When it is necessary to place a counterweight on the bag placing plate 6, place the counterweight at the input end of the conveyor 19. Since the input end of the conveyor 19 is at a relatively low height, the operator can load the materials more easily, which reduces the difficulty of loading. The counterweight moves from the input end to the output end along the conveying direction on the conveyor 19. Since the output end of the conveyor 19 is connected to the bag placing plate 6, the counterweight slides from the output end of the conveyor 19 to the bag placing plate 6. Since the input end of the conveyor 19 is at a relatively low height, it is easier to operate, so that the counterweight can be placed as close to the center as possible, ensuring that the subsequent sliding and dropping process of the counterweight on the bag placing plate 6 is more stable and accurate, which is conducive to the uniform distribution of the counterweight on the casting template 5.

[0051] Furthermore, it also includes an anchor plate 20 , which is detachably mounted on the bridge body 1 , and has a pressing portion 21 thereon, which abuts against the suspension 9 .

[0052] In this embodiment, the anchor plate 20 is installed on the bridge body 1 , and the pressing portion 21 on the anchor plate 20 abuts against the tail of the suspension 9 .

[0053] When installing the anchor plate 20, first place the anchor plate 20 in a suitable position, and fix the anchor plate 20 to the bridge body 1 by bolts or other detachable connection methods. As the anchor plate 20 is fixed, the pressing portion 21 on it tightly abuts against and presses down the tail of the suspension 9, ensuring that the suspension 9 is evenly stressed, so that the suspension 9 will not accidentally shake or move during the pre-stressing operation. When the suspension 9 needs to be adjusted or moved, the anchor plate 20 can be easily removed to release the fixation of the suspension 9 for subsequent operations.

[0054] Furthermore, it also includes a second hoist 22, a lifting plate 23 and a lifting rope 24. The second hoist 22 is arranged on the truss 2, and the two ends of the lifting rope 24 are respectively connected to the second hoist 22 and the lifting plate 23.

[0055] In this embodiment, during the bridge construction process, before the preloading test is performed, the winch 22 is started first, and the lifting rope 24 is lowered to lower the lifting plate 23 onto the casting template 5. Then, according to the normal preloading operation process, the ballast weight is dropped through the bag dropping plate 6. Since the lifting plate 23 has been placed on the casting template 5 in advance, the ballast weight will fall on the lifting plate 23.

[0056] When the preloading test is finished, the counterweight needs to be removed. At this time, the second winch 22 is started again, the second winch 22 winds the lifting rope 24, and slowly lifts the lifting plate 23. The lifting plate 23 can be lifted to a suitable operable height so that the construction personnel can easily carry the counterweight to a designated location for storage or subsequent processing.

[0057] First, by setting up the winch 22, the lifting plate 23 and the lifting rope 24, a clear landing point is provided for the counterweight before preloading, ensuring that the counterweight is accurately placed and facilitating subsequent preloading operations. Secondly, after the preloading is completed, the counterweight can be removed quickly and easily, greatly improving the construction efficiency without the need for other complex equipment. Furthermore, this design makes the entire preloading process more orderly and controllable, reducing safety risks and construction delays that may be caused by improper placement and removal of the counterweight. Finally, it provides strong support for the smooth progress of bridge construction and helps ensure the progress and quality of the project.

[0058] Furthermore, it also includes a travel track 25 , which is detachably arranged on the bridge body 1 , and the truss 2 is slidably arranged on the travel track 25 .

[0059] In this embodiment, during the bridge construction, the traveling rail 25 is first detachably installed on the bridge body 1 . Then, the truss 2 is placed on the traveling rail 25 so that the truss 2 can slide on the traveling rail 25 .

[0060] When a certain beam section needs to be constructed, the truss 2 is slid to a specified position. Then, the truss 2 is anchored to ensure that the truss 2 remains stable during the construction process. At this time, the hanging basket device can be installed and adjusted under the truss 2 to prepare for the construction of the current beam section.

[0061] After the construction of the current beam section is completed, the anchoring of the truss 2 is released. A new section of the traveling track 25 is laid in front of the traveling track 25, and the truss 2 is slid onto the new traveling track 25. Then the truss 2 is anchored again, and the above construction process is repeated, thereby realizing the construction section by section.

[0062] First, the provision of the travel track 25 enables the truss 2 to slide conveniently on the bridge body 1 and accurately reach each construction position, thereby improving the flexibility and efficiency of the construction. Secondly, the detachable travel track 25 is easy to install and disassemble, and can be adjusted and replaced according to the construction progress and needs, thereby reducing the construction cost. Furthermore, by means of anchoring and unanchoring, the stability and safety of the truss 2 during the construction process can be ensured, thereby avoiding construction accidents caused by the movement of the truss 2. Finally, this section-by-section construction method can effectively ensure the quality and progress of bridge construction, and provide reliable technical support for bridge construction.

[0063] Furthermore, it also includes a support rod 26 and a support plate 27, the support rod 26 is bolted to the truss 2, and the support plate 27 is threadedly connected to the support rod 26 for abutting the top surface of the bridge body 1, and the support plate 27 is located on the front side of the travel track 25.

[0064] In this embodiment, the support rod 26 is bolted to the truss 2, and it forms an angle with the horizontal plane, which can effectively support the gravity of the inclined truss 2. When the truss 2 moves to a certain position on the travel track 25, the support plate 27 threadedly connected to the support rod 26 is rotated to gradually approach and abut the top surface of the bridge body 1, thereby providing a stable support force for the truss 2, ensuring the stability of the truss 2 during the construction process, so that it can withstand the load from the upper hanging basket device and other construction operations.

[0065] When the truss 2 needs to move to the next beam section, the support plate 27 is rotated in the opposite direction to disengage it from the bridge body 1, so that the truss 2 can slide smoothly on the travel track 25. During the movement of the truss 2, since the support plate 27 is located in front of the fulcrum of the truss 2, once an unexpected situation occurs and causes the truss 2 to tilt forward, the support plate 27 can abut against the bridge body 1 in time to form an effective barrier to prevent the truss 2 from further tilting and causing a safety accident, thereby protecting the safety of construction personnel and equipment and ensuring the safe and orderly progress of the entire bridge construction process.

[0066] The support rods 26 and the support plates 27 provide a follow-up anti-tilt structure for the truss 2. Traditional anchoring structures need to be released when the truss 2 needs to move forward, and cannot provide protection during the movement of the truss 2. However, the support rods 26 and the support plates 27 in this embodiment can still provide support when the truss 2 accidentally tilts forward even if the contact with the bridge body 1 is released when the truss 2 moves forward, thereby greatly improving safety.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
