Description

Technical Field

[0001] This invention relates to the field of prefabricated construction of cast-in-place box girder reinforcement engineering, and in particular to a combined transport device and method for box girder reinforcement components. Background Technology

[0002] Cast-in-place box girders offer excellent integrity, ease of construction, good appearance, and strong practicality, making them a commonly used construction technique for approach bridges. However, with the upgrading of equipment technology in prefabricated construction, the traditional back-end processing and on-site binding techniques for cast-in-place box girder reinforcement construction are no longer sufficient to meet the efficiency and safety requirements of modern bridge construction. Therefore, construction companies have begun to explore prefabricated construction techniques for cast-in-place box girder reinforcement engineering, adopting a method of prefabricating box girder reinforcement components at the rear and assembling the reinforcement structure on-site to improve the efficiency of on-site reinforcement binding.

[0003] The transportation and hoisting of box girder reinforcement components from the binding station to the on-site assembly station requires corresponding construction equipment and methods. However, since the construction process for cast-in-place box girder reinforcement components is a new technology, there is no specific supporting equipment available. Therefore, current methods for transporting and hoisting box girder reinforcement components often draw on the methods used for transporting and hoisting precast concrete box girders: girder transport vehicles and bridge erecting machines, along with their associated methods. One method involves binding the box girder reinforcement components on the girder transport vehicle and then transporting them to the on-site station for hoisting with the bridge erecting machine. Another method involves binding the reinforcement components on an integral jig, then hoisting them onto the girder transport vehicle and transporting them to the on-site station, where they are then hoisted by the bridge erecting machine.

[0004] The aforementioned equipment and processes used for precast concrete box girders are primarily designed to address the characteristics of concrete structures, such as poor tensile strength and heavy weight. To ensure uniform stress distribution on the concrete box girders, the girder transport vehicles are often integral structures, and the bridge erecting machines span at least two spans, significantly increasing project construction costs. In contrast, steel reinforcement components are primarily steel structures, with lighter overall weight and extremely high tensile strength. Therefore, using the same equipment and processes as conventional precast concrete would result in unnecessary cost waste. Thus, a method and device for transporting steel reinforcement components for bridge deck box girders is proposed to address these issues. Summary of the Invention

[0005] The main objective of this invention is to provide a combined transportation device and method for box girder steel reinforcement components, thereby solving the problem of high transportation costs faced by existing box girder steel reinforcement component transportation and hoisting.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention includes:

[0007] The box girder reinforcement component forming jig is set on the cast box girder. The box girder reinforcement component forming jig includes several evenly distributed split bottom plate binding jigs and movable web plate binding jigs located on both sides of the split bottom plate binding jigs.

[0008] The modular transport vehicle consists of several liftable transport units and several connecting beams connecting adjacent transport units. The transport units are interspersed in a split-type base plate binding frame, and the connecting beams are detachably fixed to the transport units.

[0009] The box girder steel reinforcement components are installed on top of the combined transport vehicle and the split base plate binding frame;

[0010] Lifting equipment, fixed on top of the box girder reinforcement components, is used for lifting the box girder reinforcement components;

[0011] The cantilevered, simply supported bridge erecting machine is set up at the pre-set installation position of the box girder steel reinforcement components.

[0012] In a preferred embodiment, the movable web binding frame includes a web frame structure and casters disposed at the bottom of the web frame structure.

[0013] The cantilever simply supported bridge erecting machine includes load-bearing legs, a first load-bearing beam mounted on the load-bearing legs, and several mobile cranes mounted on the first load-bearing beam.

[0014] In a preferred embodiment, the transport unit includes two symmetrically arranged traveling components for moving and lifting, a load-bearing component fixed to the top of the traveling components, and a frame plate fixed to the top of the load-bearing component.

[0015] The walking assembly includes two hydraulic drive wheel sets symmetrically arranged front and rear, a main frame fixed on top of the two hydraulic drive wheel sets, a telescopic lifting frame inserted into the main frame, a lifting cylinder fixed on the main frame with its output shaft fixed to the lifting frame, and a wear-resistant plate set on the main frame for frictional contact with the lifting frame. The top of the lifting frame is fixed to the load-bearing component, and the connecting beam is fixed to both ends of the main frame by screws.

[0016] The hydraulic drive wheel assembly is equipped with a hydraulic motor for drive execution and speed control. The left and right walking components achieve steering of the combined transport vehicle through the difference in walking speed.

[0017] In the preferred embodiment, extension rods are provided on both the front and rear sides of the combined transport vehicle, and GPS antennas are fixed on the extension rods. The load-bearing components include a second load-bearing beam, as well as a hydraulic pump station and a battery built into it. The hydraulic pump station is connected to the hydraulic motor and lifting cylinder of the hydraulic drive wheel set. The battery is electrically connected to the hydraulic pump station and the GPS antenna.

[0018] In a preferred embodiment, the lifting device includes a crossbeam fixed to the top of the box girder reinforcement components, a lifting beam located at the top of the crossbeam, a lifting rod located at the bottom of the lifting beam and extendable through the crossbeam, and a tensioning cylinder located at the bottom of the lifting beam with its output shaft facing the crossbeam.

[0019] In the preferred embodiment, the crossbeam is provided with several vertical through holes for the lifting rod to pass through and horizontal through holes for fixing to the box girder steel reinforcement components. A spacing laser rangefinder is provided on the side of the crossbeam. A lifting lug is provided at the top center of the lifting beam. The lifting rod and the lifting beam are connected by a universal joint. The universal joint and the lifting beam are rotatably connected. An adaptive anchor claw is provided at the bottom of the lifting rod.

[0020] The bottom of the lifting beam is provided with a rotating seat, and the rotating seat is provided with a downward-opening T-shaped rotating groove. The top of the universal joint is fixed with a T-shaped rotating block located in the T-shaped rotating groove.

[0021] In the preferred embodiment, the adaptive anchor claw includes a thin connecting rod, a thick connecting rod, and a base that are sequentially fixed to the bottom end of the boom. The diameter of the thin connecting rod is smaller than that of the thick connecting rod and the boom. A telescopic ring and a tension spring are movably fitted on the outside of the thin connecting rod. The tension spring is located between the telescopic ring and the boom. Several anchor claws are hinged to the top of the base. The telescopic ring is hinged to the outside with the same number of connecting rods as the anchor claws. The other end of the connecting rod is hinged to the corresponding anchor claw.

[0022] The method includes:

[0023] S1. Bind the box girder steel reinforcement components. Lower the height of the combined transport vehicle to the same height as the split base plate binding jig. Then, bind the box girder steel reinforcement components in the jig composed of the split base plate binding jig, the movable web plate binding jig, and the combined transport vehicle. Then, evenly install several lifting devices on the top of the box girder steel reinforcement components.

[0024] S2. Remove the movable web binding frame and move the movable web binding frames on both sides outwards to make room for the transport of the box girder steel reinforcement components.

[0025] S3. Lifting the box girder steel reinforcement components, all lifting cylinders on the combined transport vehicle operate simultaneously, extending to their maximum stroke state to lift the box girder steel reinforcement components. At this time, the lower surface of the second load-bearing beam is above the upper surface of the split base plate binding frame.

[0026] S4. Transporting box girder steel reinforcement components: The modular transport vehicle carries the box girder steel reinforcement components across the split base plate binding jig and transports them from the binding station to the on-site installation station. During this process, the modular transport vehicle is positioned and navigated by a GPS antenna, thereby controlling the driving speed of the hydraulic drive wheel set.

[0027] S5. Lifting the box girder steel reinforcement components: After the front end of the box girder steel reinforcement components arrives at the on-site installation position, use the mobile crane closest to the installation position to lift the first lifting device at the front end. Then, lower the first transport unit at the front end to the lowest position, and then remove the connecting beam connected to it to separate it from the modular transport vehicle.

[0028] S6. Except for the detached transport unit, the combined transport vehicle continues to move forward, and the mobile crane that has completed the hoisting moves forward in sync until the combined transport vehicle and the detached transport unit are at a fixed safe distance. Then, the second mobile crane closest to the installation position is used to hoist the second lifting device at the front. The second transport unit at the front is lowered to its lowest position, and the connecting beam connected to it is removed, so that it is detached from the combined transport vehicle.

[0029] S7. Repeat step S6 until the mobile crane lifts all the lifting equipment and the cantilevered bridge erecting machine bears the weight of the box girder steel reinforcement components. At this time, all transport units are in an independent module state and all connecting beams are removed.

[0030] S8. After all lifting points of the box girder steel reinforcement components are lifted, the transportation and auxiliary lifting tasks of the modular transport vehicle are completed. The vehicle is then reassembled into a complete unit. The transport units are connected sequentially by connecting beams, and the vehicle moves backward starting from the last transport unit. The connecting beams are then installed gradually until the modular transport vehicle is reassembled into a complete unit.

[0031] S9. The combined transport vehicle returns to the lashing work area. During the return process, the GPS antenna positions and navigates the combined transport vehicle, thereby controlling the speed of the hydraulic drive wheel set.

[0032] S10. Repeat steps S1-S9 to continue transporting and hoisting the steel reinforcement components of the box girder.

[0033] In the preferred embodiment, the specific installation method of the lifting device is as follows:

[0034] S1. Install the crossbeams. Start from the rear end of the box girder steel reinforcement components and install the crossbeams sequentially from front to back. Use a spacing laser rangefinder to check the spacing between the crossbeams to ensure the accuracy of the crossbeam installation. During installation, tie the crossbeams to the top of the box girder steel reinforcement components through transverse perforations.

[0035] S2. Install the lifting beam and the hanger. Move the lifting beam to the top of the crossbeam so that the hanger passes through the corresponding vertical through hole. When the self-adaptive anchor passes through the vertical through hole and the box girder reinforcement component, the anchor is compressed by the pressure from below, thus passing through the vertical through hole and the box girder reinforcement component. When passing through the box girder reinforcement component, the angle of the hanger can be adjusted appropriately through the rotatable universal joint.

[0036] S3. Tension the adaptive anchor claws, activate the tensioning cylinder to lift the lifting beam, the boom, and the adaptive anchor claws, so that the anchor claws are anchored to the bottom of the box girder reinforcement components.

[0037] This invention provides a combined transport device and method for box girder steel reinforcement components, which has the following beneficial effects:

[0038] 1. By setting up a combination transport vehicle and a box girder steel reinforcement component forming jig, the box girder steel reinforcement components can be directly tied on the combination transport vehicle. The box girder steel reinforcement components can be directly lifted and transported by the lifting of the combination transport vehicle. The conversion of the entire system is extremely convenient, without the need for large hoisting equipment. The method is simple, and its lifting function can be effectively used in conjunction with the split base plate binding jig and the cantilever simply supported bridge erecting machine.

[0039] 2. The modular transport vehicle, composed of multiple transport units and connecting beams, provides high flexibility in transporting box girder steel reinforcement components, occupies less space, and is more convenient to coordinate with cantilevered bridge erecting machines. A set of mobile cranes can be connected to the box girder steel reinforcement components, and then a set of transport units can be disconnected from them, allowing for gradual transfer of the box girder steel reinforcement components onto the mobile cranes, significantly improving safety. Furthermore, the connecting beams link them together as a whole, facilitating positioning and movement as a whole. Additionally, the number of transport units can be quickly adjusted according to the needs of the box girder steel reinforcement components.

[0040] 3. By setting up a GPS antenna, the transportation process can be automated, which can save some manpower to a certain extent. In addition, the connecting beam can effectively control the distance between each transportation unit, prevent damage to the steel reinforcement components of the box girder, and facilitate positioning and movement of the whole.

Detailed Implementation

[0066] Example 1

[0067] like Figure 1-9 As shown, a modular transportation device and method for box girder reinforcing steel components is proposed. Addressing the characteristics of box girder reinforcing steel components, such as their light weight and flexible structure, this invention starts with a transport vehicle for these components and combines it with an extended single-span simply supported bridge erecting machine. A novel transportation equipment and construction method are proposed. Based on a modular transport vehicle for box girder reinforcing steel components, the components are transferred from the binding area to the work area. Then, in collaboration with the extended single-span simply supported bridge erecting machine, the components are hoisted point-by-point and section-by-section. Compared to traditional precast concrete box girders, this significantly reduces equipment costs. The invention also proposes new transportation equipment and hoisting methods for reinforcing steel components, specifically including:

[0068] The box girder reinforcement component forming jig is set on the cast-in-place box girder. The box girder reinforcement component forming jig includes several evenly distributed split-type bottom plate binding jigs 1 and movable web plate binding jigs 2 located on both sides of the split-type bottom plate binding jigs 1.

[0069] In this embodiment, the movable web binding frame 2 includes a web frame structure 202 and casters 201 fixed to the bottom of the web frame structure 202. The web frame structure 202 can be moved by the casters 201 at the bottom. After the box girder reinforcement components 5 are bound, the movable web binding frames 2 on both sides can be moved outward to facilitate the lifting and transportation of the box girder reinforcement components 5. In this embodiment, the number of split bottom plate binding frames 1 is five.

[0070] The combined transport vehicle 3 is composed of a number of liftable transport units 31 and a number of connecting beams 32 that connect adjacent transport units 31. The transport units 31 are interspersed in the split-bottom lashing jig 1, and the connecting beams 32 and the transport units 31 are fixedly connected in a detachable manner.

[0071] In this embodiment, the transport unit 31 includes two walking components 313 that are symmetrically arranged left and right and are used for walking and lifting, a load-bearing component 311 fixedly arranged at the top of the walking components 313, and a jig plate 312 fixedly arranged on the top of the load-bearing component 311.

[0072] In a preferred solution, the walking component 313 includes two hydraulically driven wheel sets 3132 that are symmetrically arranged front and back, a main frame 3131 fixedly arranged at the top of the two hydraulically driven wheel sets 3132, a lifting frame 3133 that is telescopically inserted into the main frame 3131, a lifting oil cylinder 3134 fixedly arranged on the main frame 3131 and whose output shaft is fixedly connected to the lifting frame 3133, and a wear-resistant plate 3135 arranged on the main frame 3131 for frictional contact with the lifting frame 3133. The top end of the lifting frame 3133 is fixedly connected to the load-bearing component 311, and the connecting beam 32 is fixedly connected to both ends of the main frame 3131 by screws.

[0073] Among them, the main frame 3131 is welded by a plurality of hollow steel pipes and is in the shape of "艹". The lifting frame 3133 can be telescopically inserted into both of its two vertical steel pipes. The lifting oil cylinder 3134 is fixedly arranged on the outer wall surface of the vertical steel pipe for pushing the lifting frame 3133 to lift and lower, and the wear-resistant plate 3135 is arranged at the top end of the vertical steel pipe.

[0074] It should be noted that a hydraulic motor for driving and executing is arranged in the hydraulically driven wheel set 3132, and speed control can be performed. The left and right two walking components 313 realize the steering of the combined transport vehicle 3 through the walking speed difference.

[0075] Extension rods 33 are fixedly arranged on both the front and rear sides of the combined transport vehicle 3. The extension rods 33 are arranged on the two outermost transport units 31. A GPS antenna 34 is fixedly arranged on the extension rods 33. The load-bearing component 311 includes a second load-bearing beam, and a hydraulic pump station 8 and a storage battery 7 built therein. The hydraulic pump station 8 is传动连接 to the hydraulic motor of the hydraulically driven wheel set 3132 and the lifting oil cylinder 3134. The storage battery 7 is electrically connected to the hydraulic pump station 8 and the GPS antenna 34. The hydraulic pump station 8 provides operating power, and the storage battery 7 provides electric power.

[0076] Among them, the second load-bearing beam is a frame structure welded by a bottom plate and rectangular steel pipes.

[0077] It should be noted that the part "传动连接" in the original text seems to be an incorrect expression. It might be "drivably connected" or other appropriate terms. Please check and correct it according to the actual situation.It should be noted that the hydraulic pump station 8, the battery 7, and the GPS antenna 34 are electrically connected to the controller, which receives signals and controls the operation of the aforementioned actuators.

[0078] The box girder steel reinforcement component 5 is set on top of the split transport vehicle 3 and the split base plate binding frame 1.

[0079] The lifting device 6 is fixed on the top of the box girder steel reinforcement component 5 and is used for lifting the box girder steel reinforcement component 5.

[0080] The cantilevered simply supported bridge erecting machine 4 is set at the preset installation position of the box girder steel reinforcement component 5.

[0081] In this embodiment, the main body of the simply supported part of the cantilever simply supported bridge erecting machine 4 occupies the length of one span of the cast-in-place span, and a cantilever extends out from the left end. The cantilever simply supported bridge erecting machine 4 includes a load-bearing leg 401, a first load-bearing beam 402 fixed on the load-bearing leg 401, and several mobile cranes 403 that are movably hung on the first load-bearing beam 402.

[0082] Example 2

[0083] Further explanation in conjunction with Example 1, such as Figure 16-23 The structure shown illustrates a method for transporting box girder steel reinforcement components in an assembled manner. This method includes:

[0084] S1. Tie the box girder steel reinforcement component 5. Lower the height of the combined transport vehicle 3 to the same height as the split base plate binding frame 1. Then, tie the box girder steel reinforcement component 5 in the frame composed of the split base plate binding frame 1, the movable web plate binding frame 2 and the combined transport vehicle 3. Then, evenly install several lifting devices 6 on the top of the box girder steel reinforcement component 5.

[0085] S2. Remove the movable web binding frame 2 and move the movable web binding frames 2 on both sides outward to make room for the transport of the box girder steel reinforcement components 5.

[0086] S3. Lifting the box girder steel reinforcement component 5, all lifting cylinders 3134 on the combined transport vehicle 3 operate simultaneously, extending to the maximum stroke state, lifting the box girder steel reinforcement component 5. At this time, the lower surface of the second load-bearing beam is above the upper surface of the split base plate binding frame 1.

[0087] S4, transport box girder steel reinforcement components 5, the combined transport vehicle 3 carries the box girder steel reinforcement components 5 across the split base plate binding frame 1, and transports them from the binding station to the on-site installation station. During this process, the combined transport vehicle 3 is positioned and navigated by the GPS antenna 34, thereby controlling the driving speed of the hydraulic drive wheel set 3132.

[0088] S5. Hoisting box girder steel reinforcement component 5. After the front end of box girder steel reinforcement component 5 arrives at the on-site installation position, use the mobile crane 403 closest to the installation position to hoist the first lifting device 6 at the front end. Then, the first transport unit 31 at the front end is lowered to the lowest state, and then the connecting beam 32 connected to it is removed to separate it from the combined transport vehicle 3.

[0089] S6. Except for the detached transport unit 31, the combined transport vehicle 3 continues to move forward, while the mobile crane 403 that has completed the hoisting moves forward in sync until the combined transport vehicle 3 and the detached transport unit 31 are at a fixed safe distance. Then, the second mobile crane 403 closest to the installation position is used to hoist the second lifting device 6 at the front end. The second transport unit 31 at the front end is lowered to its lowest position, and the connecting beam 32 connected to it is removed, so that it is detached from the combined transport vehicle 3.

[0090] S7. Repeat step S6 until the mobile crane 403 lifts all the lifting devices 6 and the cantilever simple support bridge erecting machine 4 bears all the weight of the box girder steel reinforcement components 5. At this time, all transport units 31 are in an independent module state and all connecting beams 32 are completely removed.

[0091] After all lifting points of the box girder steel reinforcement component 5 are lifted, the transportation and auxiliary lifting tasks of the modular transport vehicle 3 are completed. The vehicle begins to be reassembled into a complete unit. The transport units 31 are connected sequentially through the connecting beams 32, and the vehicle moves backward starting from the last transport unit 31. Then the connecting beams 32 are installed step by step until the modular transport vehicle 3 is reassembled into a complete unit.

[0092] S9. The combined transport vehicle 3 returns to the tying work area. During the return process, the GPS antenna 34 positions and navigates the combined transport vehicle 3, thereby controlling the driving speed of the hydraulic drive wheel set 3132.

[0093] S10. Repeat steps S1-S9 to continue transporting and hoisting the box girder steel reinforcement component 5.

[0094] Example 3

[0095] Further explanation in conjunction with Example 1, such as Figure 10-15 As shown, the lifting device 6 includes a crossbeam 601 fixed to the top of the box girder reinforcement component 5, a lifting beam 602 located at the top of the crossbeam 601, a lifting rod 604 located at the bottom of the lifting beam 602 and extendable through the crossbeam 601, and a tensioning cylinder 603 located at the bottom of the lifting beam 602 with its output shaft facing the crossbeam 601.

[0096] In this embodiment, there are four booms 604. It should be noted that the length of the booms 604 can be adjusted as needed.

[0097] In the preferred embodiment, the crossbeam 601 is provided with several vertical through holes 6011 for the hanger rod 604 to pass through and horizontal through holes 6013 for fixing to the box girder reinforcement component 5. The number of vertical through holes 6011 is adapted to the number of hanger rods 604, and the diameter of the vertical through holes 6011 is at least twice the diameter of the hanger rod 604. A spacing laser rangefinder 6012 is fixed on the side of the crossbeam 601 for measuring the spacing between adjacent crossbeams 601. A lifting lug 6020 is fixed at the top center of the lifting beam 602. The hanger rod 604 and the lifting beam 602 are connected by a universal joint 606. The universal joint 606 and the lifting beam 602 are rotatably connected, which facilitates small-amplitude adjustment of the insertion angle of the hanger rod 604 and avoids the inability to pass through the box girder reinforcement component 5. An adaptive anchor claw 605 is provided at the bottom of the hanger rod 604.

[0098] The bottom of the lifting beam 602 is fixedly provided with a rotating seat 6021, and the rotating seat 6021 is provided with a downward-opening T-shaped rotating groove 6022. The top of the universal joint 606 is fixedly provided with a T-shaped rotating block 6061 located in the T-shaped rotating groove 6022, so that the top of the universal joint 606 can rotate under the lifting beam 602.

[0099] In a preferred embodiment, the adaptive anchor claw 605 includes a thin connecting rod 6051, a thick connecting rod 6052, and a base 6053, which are sequentially fixed to the bottom end of the boom 604. The diameter of the thin connecting rod 6051 is smaller than that of the thick connecting rod 6052 and the boom 604. A telescopic ring 6055 and a tension spring 6054 are movably fitted on the outside of the thin connecting rod 6051. The inner diameters of the telescopic ring 6055 and the tension spring 6054 are both smaller than those of the thick connecting rod 6052 and the boom 604. The tension spring 6054 is located between the telescopic ring 6055 and the boom 604. Several anchor claws 6057 are hinged to the top of the base 6053. The telescopic ring 6055 is hinged to the outside with the same number of connecting rods 6056 as the anchor claws 6057. The other end of the connecting rod 6056 is hinged to the corresponding anchor claw 6057. In this embodiment, there are five connecting rods 6056 and five anchor claws 6057.

[0100] When in use, when the anchor claw 6057 is subjected to a force from below, the connecting rod 6056 pushes the telescopic ring 6055 to compress the tension spring 6054, thereby achieving the effect of retracting the anchor claw 6057. This makes it easier for the anchor claw 6057 to pass through the vertical through hole 6011 and the hole on the box girder steel reinforcement component 5. After passing through, it quickly opens due to the tension of the tension spring 6054. At the same time, when the top of the anchor claw 6057 contacts the box girder steel reinforcement component 5, it can be quickly anchored.

[0101] The specific installation method is as follows:

[0102] S1. Install the crossbeams 601. Start from the rear end of the box girder steel reinforcement component 5 and install the crossbeams 601 sequentially from the front. Use a laser distance measuring instrument 6012 to detect the spacing between the crossbeams 601 to ensure the accuracy of the crossbeam installation.
