Description

Technical Field

[0001] This invention belongs to the field of bridge construction technology, specifically relating to a multifunctional hanging basket device for realizing the modular construction of steel reinforcement components for bridge main beams. Technical Background

[0002] With the popularization of advanced construction concepts such as standardization and prefabrication, the modular construction technology of steel reinforcement has been gradually promoted in the construction of super high bridge piers and towers. However, due to the constraints of construction equipment, this technology has not been realized in the construction of main beams. The main reason is that the cantilever construction of main beams is generally completed by hanging basket equipment, but traditional hanging basket equipment does not have hoisting function. If the steel reinforcement of the main beam segments is hoisted by conventional hoisting structures, on the one hand, the design height of the hoisting frame is at least 10m, which is not conducive to the overall stability of the hoisting structure; on the other hand, the hoisting frame cannot move with the hanging basket system to realize the modular construction of steel reinforcement of the main beam segments throughout the entire bridge, and frequent handling of the hoisting frame makes it difficult to improve construction efficiency. Summary of the Invention

[0003] In view of this, the present invention aims to provide a multifunctional hanging basket device for realizing the modular construction of the main beam reinforcement of bridges, so as to solve the technical problem of low integration between the hanger and the hanging basket in the prior art, which affects the construction efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A multifunctional hanging basket device for modular construction of bridge main beam reinforcement components includes a hoisting unit located above the main beam and a hanging basket unit fixedly connected to the bottom of the hoisting unit. A traveling unit is provided between the hoisting unit and the main beam. The hoisting unit includes two horizontal beams at the bottom and a frame at the top. The extension direction of the horizontal beams is consistent with the width direction of the main beam. Multiple columns are provided between the horizontal beams and the frame. The hanging basket unit includes trough-shaped hanging beams located on both sides of the main beam. The trough-shaped hanging beams include a vertical section and a horizontal section facing the side of the main beam. The vertical section of the trough-shaped hanging beam is fixedly connected to the end of the horizontal beam. The horizontal section of the trough-shaped hanging beam is fixedly connected to a horizontal load-bearing main truss facing the uncast section of the main beam. The ends of the load-bearing main trusses on both sides of the main beam are connected and fixed through front hanging beams. The traveling unit includes a track, and a pad beam is provided between the track and the main beam. The bottom surface of the horizontal beam is provided with a sliding shoe that cooperates with the track.

[0006] Furthermore, a load-bearing mechanism is provided below the main truss, the load-bearing mechanism including a rear lower crossbeam and a front lower crossbeam arranged sequentially along the extension direction of the main beam, and multiple bottom distribution beams are evenly spaced between the rear lower crossbeam and the front lower crossbeam and the bottom surface of the main beam along the width direction of the main beam, the bottom distribution beams extending to the cast-in-place section of the main beam; the trough-shaped hanging beam is lifted and fixed to the rear lower crossbeam, and the front hanging beam is lifted and fixed to the front lower crossbeam.

[0007] Furthermore, during the pouring process, the lower rear crossbeam is also lifted and fixed to the bottom plate of the main beam.

[0008] Furthermore, the track is made of I-beams, and the bottom of the slipper has a connecting groove that matches the upper wing plate of the track. The opening of the connecting groove faces downwards, and limit plates are formed on both sides of the opening inwards.

[0009] Furthermore, it also includes steel bar segments, with a cuboid stiffening frame at the center of the interior of the steel bar segment. The stiffening frame is fixedly connected to the steel bar segment, and a rectangular skylight is opened at the center of the top of the steel bar segment.

[0010] Furthermore, the frame includes a slide beam extending along the length of the main beam. A first longitudinal beam and a second longitudinal beam are symmetrically arranged on both sides of the slide beam. The bottom surfaces of the slide beam, the first longitudinal beam, and the second longitudinal beam are all located in the same horizontal plane. Side beams are provided on the outer sides of the first longitudinal beam and the second longitudinal beam. A sliding groove is opened on the bottom surface of the slide beam. A crane is slidably connected to the bottom of the slide beam. A rotating hoist is suspended directly below the crane. The main hoisting rope on the rotating hoist passes through the skylight and is welded and fixed to the bottom corner of the rigid frame through four auxiliary hoisting ropes. Each auxiliary hoisting rope corresponds to one of the bottom corners.

[0011] Furthermore, a circular lifting plate is provided between the main lifting rope and the auxiliary lifting rope. The lower end of the main lifting rope is fixedly connected to the center of the top surface of the lifting plate. The bottom surface of the lifting plate has a fan-shaped sliding groove, which corresponds one-to-one with the auxiliary lifting rope and is opposite to the bottom corner of the rigid frame. A slider is slidably connected in the sliding groove. A spring is provided between the slider and the side wall of the sliding groove. A connecting post is provided on the bottom surface of the slider. The auxiliary lifting rope is fixedly connected to the slider through the connecting post.

[0012] Furthermore, a first steering ring is fixedly connected to the periphery of the overhead crane. An annular rotating track is opened on the outer surface of the first steering ring. Sliding rods are symmetrically arranged on both sides of the first steering ring. The sliding rods are slidably connected to the sliding groove. The top of the sliding rod is slidably connected to the rotating track through a horizontal rotating rod. A vertical telescopic rod is fixedly connected to the bottom of the sliding rod. The telescopic rod passes through the skylight at the top of the steel bar segment and is welded to the top surface of the hanging platform.

[0013] Furthermore, a second steering ring is provided at the front end of the slide beam. The second steering ring is symmetrical about the slide beam. The bottom of the slide beam and the bottom of the first longitudinal beam and the second longitudinal beam are all provided with slots. The second steering ring is inserted into the slots. The bottom surface of the second steering ring is in the same horizontal plane as the bottom surface of the slide beam. The bottom of the second steering ring is provided with an annular reversing track. The inner diameter of the reversing track is consistent with the distance between the slide rods on both sides. The size of the reversing track is consistent with the size of the slide groove, and the junction of the reversing track and the slide groove is interconnected.

[0014] The beneficial effects of this invention are as follows:

[0015] (1) Compared with the prior art, the present invention adds a hoisting unit to the traditional hanging basket construction equipment. On the one hand, it realizes the overall hoisting, transportation and overall placement of the steel reinforcement segments into the formwork. On the other hand, the two processes of steel reinforcement binding and assembly and concrete pouring and curing of the main beam are carried out in an overlapping manner, which makes the construction period more efficient.

[0016] (2) By adding a series of buffer components such as a hoisting plate and a sliding rod, it can not only effectively resist wind load and prevent the steel bar segments from deflecting too much during hoisting, thus causing safety accidents, but also improve the stability of the steel bar segments during lifting, moving and falling, thereby ensuring the accuracy of the steel bar segments when they are positioned, avoiding multiple adjustments and improving construction efficiency.

[0030] Example 1, see details Figures 1-10 .

[0031] like Figure 1 As shown, a multifunctional hanging basket device for realizing modular construction of steel reinforcement in bridge main beams includes a hoisting unit 1 located above the main beam 6 and a hanging basket unit 2 fixedly connected to the bottom of the hoisting unit 1. A traveling unit 3 is provided between the hoisting unit 1 and the main beam 6.

[0032] like Figure 1The hoisting unit 1 includes a hoisting gantry 101, which comprises a bottom crossbeam 1011 and a top frame. The crossbeam 1011 extends along the width of the main beam 6. In this embodiment, to enhance the stability of the hoisting gantry 101, two crossbeams 1011 are spaced apart along the extension direction of the main beam 6 to enhance the overturning resistance of the hoisting gantry 101. The crossbeams 1011 are connected and fixed to the main beam by hoisting anchor jacks 121. Four spaced columns 1012 are provided between the crossbeams 1011 and the frame to connect and support them. Diagonal braces 102 are provided on the outer side of the columns 1012. One end of the diagonal brace 102 is welded to the top surface of the crossbeam 1011, and the other end of the diagonal brace 102 is welded to the outer side of the column 1012. The diagonal braces 102 provide lateral support to the hoisting gantry 101, thereby further improving the stability of the hoisting gantry 101.

[0033] The frame includes a slide beam 103 extending along the length of the main beam 6. A first longitudinal beam 104 and a second longitudinal beam 105 are symmetrically arranged on both sides of the slide beam 103. Side beams 120 are provided on the outer sides of the first longitudinal beam 104 and the second longitudinal beam 105. It should be emphasized that in this embodiment, the bottom surfaces of the slide beam 103, the first longitudinal beam 104 and the second longitudinal beam 105 are all located in the same horizontal plane.

[0034] The hanging basket unit 2 includes a trough-shaped hanging beam 201 located on both sides of the main beam 6 and welded to the end of the crossbeam 1011. In this embodiment, the trough-shaped hanging beam 201 is "L"-shaped, with the vertical section of the trough-shaped hanging beam 201 facing the bottom of the crossbeam 1011 and the horizontal end of the trough-shaped hanging beam 201 facing the side of the main beam 6 and leaving a gap with the side of the main beam 6. A load-bearing main truss 202 is fixedly connected to the end of the horizontal section of the trough-shaped hanging beam 201. The extension direction of the load-bearing main truss 202 is consistent with the extension direction of the main beam 6. In the height direction, the load-bearing main truss 202 is located in the middle of the main beam 6. It should be noted that in this embodiment, the load-bearing main truss 202 is located on both sides of the main beam 6 and extends horizontally. A front hanging beam 210 extending along the width direction of the main beam 6 is welded to one end of the load-bearing main truss 202 located in the uncast section. The end of the load-bearing main truss 202 near the hoisting gantry 101 is fixed to the end of the horizontal section of the trough-shaped hanging beam 201 by welding.

[0035] like Figure 1 , Figure 2As shown, the load-bearing mechanism includes a rear lower crossbeam 203 and a front lower crossbeam 204 located below the main truss 202 and sequentially arranged along the extension direction of the main beam 6. The rear lower crossbeam 203 is located directly below the front channel-shaped hanging beam 201, and the front lower crossbeam 204 is located directly below the front hanging beam 210. It should be noted that in this embodiment, "front" refers to the extension direction of the main beam 6, and so on, without further explanation. Multiple bottom distribution beams 205 are evenly spaced along the width direction of the main beam 6 between the rear lower crossbeam 203 and the bottom surface of the main beam 6 and the front lower crossbeam 204. The bottom distribution beams 205 extend to the already cast section of the main beam 6 and are made of I-beams to enhance the vertical load-bearing capacity.

[0036] The top surface of the horizontal section of the front channel-shaped hanging beam 201 is threadedly connected to a rear lifting jack 207, which includes a steel sling that passes through the horizontal section of the front channel-shaped hanging beam 201 and the rear lower crossbeam 203. The top surface of the front hanging beam 210 is threadedly connected to a front lifting jack 206, which also includes a steel sling that passes through the front hanging beam 210 and the front lower crossbeam 204. By tightening the steel slings with the rear lifting jack 207 and the front lifting jack 206, the load-bearing mechanism comes into contact with and is pressed against the bottom surface of the main beam 6.

[0037] The lower load-bearing mechanism, the upper main truss 202, and the front hanging beam 210 together form a support system for installing the concrete formwork 209, and provide support for the subsequent hoisting of the reinforcing steel segment 501 and the pouring of concrete. In this embodiment, to further optimize the support system, during the pouring stage, the lower rear crossbeam 203 and the bottom plate of the main beam 6 are also equipped with rear anchoring jacks 208. The rear anchoring jacks 208 tighten and anchor the lower rear crossbeam 203 and the main beam 6 to improve the load-bearing capacity of the load-bearing mechanism and enhance the stability of the entire hanging basket unit 2.

[0038] like Figure 1 , Figure 3As shown, a traveling unit 3 is also provided between the hoisting gantry 101 and the top surface of the main beam 6. In this embodiment, the traveling unit 3 includes a track 302 arranged along the extension direction of the main beam 6. Below the track 302, multiple pad beams 301 are arranged at intervals along the extension direction of the track 302. The extension direction of the pad beams 301 is consistent with the width direction of the main beam 6. The pad beams 301, the track 302, and the pressure beams are stacked sequentially from bottom to top, and the track 302 is anchored by applying preload between the pressure beams and the top plate of the main beam 6 using jacks. By setting the pad beams 301, on the one hand, the pad beams 301 can level the track 302, so that the upper surface of the track 302 is in the same horizontal plane, which is conducive to the sliding of the hoisting gantry 101; on the other hand, it can effectively increase the contact area between the track 302 and the main beam 6, and the pad beams 301 can disperse the force above the track 302 to both sides, avoiding deformation and damage to the bottom of the track 302 due to stress concentration. In addition, the pad beam 301 can serve as a buffer structure. When the track 302 is subjected to sudden loads (such as the moment of lifting during hoisting), the energy is dissipated through the elastic deformation of the pad beam 301 itself, preventing excessive stress from damaging the surface of the main beam 6.

[0039] In this embodiment, the track 302 is made of I-beam steel, with ribs 3021 on both sides of its web to improve local stability. A sliding shoe 303 is provided between the track 302 and the lifting gantry 101. The top of the sliding shoe 303 is threaded to the bottom of the lifting gantry 101, and the bottom of the sliding shoe 303 has a connecting groove adapted to the upper flange of the track 302. The opening of the connecting groove faces downward, and limit plates are formed on both sides of the opening. The connecting groove and the limit plates can effectively prevent the lifting gantry 101 from overturning above the track 302, thereby improving the overturning resistance of the entire lifting unit 1. A pressure beam is also provided on the top of the track 302 to anchor the track 302 and prevent the track 302 from shifting.

[0040] The aforementioned walking unit 3 enables synchronous displacement of the hoisting unit 1 and the hanging basket unit 2, enhancing the mobility of the hoisting unit 1 and improving construction efficiency.

[0041] Reinforcing bar segment 501 is located in the already cast section of the main beam 6, that is, behind the hoisting gantry 101, such as... Figure 1As shown, the completed reinforcing bar segment 501 is placed directly below the hoisting gantry 101. A rectangular rigid frame 503 is located at the center of the reinforcing bar segment 501. The top and bottom of the rigid frame 503 are tied to the reinforcing bar segment 501 to achieve a fixed connection. Notably, in this embodiment, a rectangular skylight 502 is provided at the center of the top of the reinforcing bar segment 501. A groove 1031 is provided on the bottom surface of the slide beam 103. The gantry crane 106 is slidably connected to the slide beam 103 through the groove 1031. A rotating hoist 107 is suspended directly below the gantry crane 106. The main hoisting rope 108 on the rotating hoist 107 passes through the skylight 502 and is welded to the bottom corners of the rigid frame 503 via four auxiliary hoisting ropes 114, with each auxiliary hoisting rope 114 corresponding to a bottom corner.

[0042] By setting up the skylight 502 and the rigid frame 503, the lifting point is moved down to the interior of the steel reinforcement segment 501, which can significantly reduce the height of the hoisting gantry 101, thereby improving the stability of the hoisting gantry 101. When the steel reinforcement segment 501 is placed in the state of waiting to be poured, the width of the steel reinforcement segment 501 is greater than the distance between the two side columns 1012. First, the steel reinforcement segment 501 is adjusted by the rotating hoist 107 so that the steel reinforcement segment 501 is rotated to a suitable angle (the width direction of the steel reinforcement segment 501 is consistent with the extension direction of the main beam 6); then, under the traction of the crane 106, the steel reinforcement segment 501 passes through the hoisting gantry 101 and moves to directly above the concrete formwork 209; finally, the angle of the steel reinforcement segment 501 is adjusted by the rotating hoist 107 to match the concrete formwork 209, and with the assistance of the crane 106, the steel reinforcement segment 501 is placed in position, thereby realizing the overall placement into the formwork.

[0043] Example 2

[0044] The difference from Embodiment 1 is that, in this embodiment, as... Figures 4-6As shown, a circular lifting plate 109 is provided between the main lifting rope 108 and the auxiliary lifting rope 114. The lower end of the main lifting rope 108 is welded to the center of the top surface of the lifting plate 109. A fan-shaped sliding groove 110 is formed on the bottom surface of the lifting plate 109. It is important to emphasize that the sliding groove 110 corresponds one-to-one with the auxiliary lifting rope, and the sliding groove 110 is opposite to the bottom corner of the rigid frame 503. Limiting grooves 1101 are formed on both sides of the sliding groove 110. Limiting protrusions 1111 that match the limiting grooves 1101 are provided on both sides of the slider 111, allowing the slider 111 to slide slidably connect to the sliding groove 110. Springs 112 are provided on both sides of the slider 111. One end of the spring 112 is welded to the side of the slider 111, and the other end is welded to the end face of the sliding groove 110, providing elastic support for the slider 111 through the springs 112. A cylindrical connecting post 113 is welded to the bottom surface of the slider 111. One end of the auxiliary suspension rope 114 is welded to the end of the connecting post 113, and the other end of the auxiliary suspension rope 114 is welded to the bottom corner of the rigid frame 503 for fixation.

[0045] like Figure 7 , Figure 8 As shown, in this embodiment, the outer shell of the overhead crane 106 is rectangular, and a first steering ring 117 is provided with the center point of the outer shell as the center. The first steering ring 117 is horizontal and there is a gap between the first steering ring 117 and the slide beam 103. Multiple connecting rods 118 distributed circumferentially are provided between the first steering ring 117 and the outer shell of the overhead crane 106. One end of the connecting rod 118 is welded to the outer shell of the overhead crane 106, and the other end of the connecting rod 118 is welded to the inner side of the first steering ring 117.

[0046] The first steering ring 117 has symmetrically arranged sliding rods 115 on both sides. In this embodiment, the sliding rods 115 are continuously bent, with a vertical section at the top, a horizontal section that tapers inward in the middle, and a vertical section at the bottom. The top of the sliding rod 115 is adapted to the sliding groove 1031 to achieve a sliding connection between the sliding rod 115 and the slide beam 103. Limiting grooves are opened on both sides of the sliding groove 1031, and a limiting block adapted to the limiting groove is also installed at the top of the sliding rod 115 to prevent the sliding rod 115 from disengaging from the slide beam 103 during sliding. A rotating track 1171 is opened on the outer surface of the first steering ring 117. A rotating rod 1151 parallel to the slide beam 103 is arranged between the top vertical section of the sliding rod 115 and the outer surface of the first steering ring 117. One end of the rotating rod 1151 is welded to the outer surface of the sliding rod 115, and the other end of the rotating rod 1151 is slidably connected to the rotating track 1171.

[0047] A vertical telescopic rod 116 is welded to the bottom end of the sliding rod 115. The telescopic rod 116 passes through the skylight 502 at the top of the steel bar segment 501 and is welded to the top surface of the hanging plate 109.

[0048] During hoisting, especially in windy conditions such as crossing canyons and high altitudes, the steel reinforcement segment 501 is prone to deflection or rotation around the main hoisting rope 108 under wind load. Under the action of the hoisting platform 109, the auxiliary hoisting rope 114 can rotate along the sliding groove 110 via the slider 111. The springs 112 on both sides of the slider 111 provide elastic support for the slider 111. On the one hand, this buffers the wind load acting on the steel reinforcement segment 501, reducing the deflection angle of the steel reinforcement segment 501; on the other hand, it prevents damage to the connection between the auxiliary hoisting rope 114 and the main hoisting rope 108 due to excessive force. In addition, the sliding rod 115 and the telescopic rod 116 installed above the hoisting platform 109 can limit the movement of 109, transferring the external load on the hoisting platform 109 to the hoisting gantry 101 above.

[0049] The front end of the slide beam 103 is provided with such Figure 7 , Figure 9 The second steering ring 119 shown is symmetrical about the slide beam 103. In this embodiment, the bottom of the slide beam 103 and the bottoms of the first longitudinal beams 104 and the second longitudinal beams 105 on both sides are provided with slots. The second steering ring 119 is inserted into the slide beam 103 and the first longitudinal beams 104 and the second longitudinal beams 105 on both sides and welded to it. After fixing, the bottom surface of the second steering ring 119 is exactly in the same horizontal plane as the bottom surface of the slide beam 103. The bottom of the second steering ring 119 has an annular deflection track 1191. The inner diameter of the deflection track 1191 is equal to the distance between the two slide rods 115. The size of the deflection track 1191 is the same as the size of the slide groove 1031, and the junction of the deflection track 1191 and the slide groove 1031 is interconnected.

[0050] During the hoisting process, the overhead crane 106 and the sliding rod 115 move together along the chute 1031 to the front end of the slide beam 103, directly above the concrete formwork 209. The overhead crane 106 is located at the center of the second steering ring 119, and the sliding rods 115 on both sides of the overhead crane 106 enter the junction of the chute 1031 and the reversing track 1191. Under the driving action of the rotary lifting device 107, the lifting platform 109 and the reinforcing bar segment 501 rotate. During this process, the rotating rod 1151 rotates around the rotating track 1171 while the sliding rod 115 rotates along the reversing track 1191. Through the setting of the first steering ring 117 and the second steering ring 119, in coordination with the rotation of the reinforcing bar segment 501, the continuous limiting of the reinforcing bar segment 501 is achieved, avoiding excessive deflection of the reinforcing bar segment 501 under the action of the rotary lifting device 107 and wind load, which would pose a threat to the surrounding existing structures and personnel. In addition, during the sinking process of the steel bar segment 501, limiting the steel bar segment 501 can ensure the accuracy of the placement, avoid multiple adjustments, and improve construction efficiency.

[0051] Example 3

[0052] The difference between this embodiment and embodiment one is that a counterweight unit 4 is also provided, such as... Figure 10 As shown, a connecting groove 1201 is formed on the outer surface of the side beam 120. The drive motor 402 is slidably connected to the side beam 120 through the connecting groove 1201. A counterweight 401 is slidably connected to the bottom of the side beam 120. The drive motor 402 and the counterweight 401 are connected and fixed by a connecting bent rod 403. A transmission gear is keyed to the output shaft of the drive motor 402. A gear rail 404 that meshes with the transmission gear is welded to the side beam 120. The counterweight unit 4 also includes a microcontroller 405 and a distance sensor 406 electrically connected to the microcontroller 405. The microcontroller 405 is electrically connected to the drive motor 402. In this embodiment, the microcontroller 405 is a SIMATIC S7-1200 and the distance sensor 406 is a VL53L0X. The distance sensor 406 collects the position of the steel bar segment 501 and transmits the position signal to the microcontroller 405. The microcontroller 405 receives the position signal and analyzes and calculates the position signal according to the predetermined program. Then, it transmits the execution signal to the drive motor 402. The drive motor 402 drives the counterweight 401 to move along the side beam 120 according to the execution signal, thereby adjusting the relative position of the counterweight 401 and the steel bar segment 501 to achieve torque balance between the two.

[0053] In addition, when the front pouring is completed and the entire device needs to be moved, the center of gravity of the entire device can be adjusted by the counterweight unit 4, so that the hoisting unit 1 and the hanging basket unit 2 can move more smoothly along the track 302, preventing excessive forward or backward tilting.

[0054] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
