Description

Technical Field

[0001] The invention relates to the technical field of building construction equipment, in particular to a large-diameter artificial bored pile reinforcement cage construction equipment, and also to a construction method for the large-diameter artificial bored pile reinforcement cage construction equipment. Background Art

[0002] In complex terrains such as landslide control and highway bridge construction, large-diameter bored piles are widely used due to their high pull-out bearing capacity and convenient construction. In the traditional processing method, the steel cage is processed horizontally on the ground, and then the steel cage is hoisted into the pile hole using lifting equipment. However, when processing the steel cage on the ground, one side of the steel cage always faces the ground, which is not convenient for processing. At the same time, the steel cage will be deformed during the hoisting process.

[0003] The existing technology usually adopts the technology of making steel cage in the hole. By building a construction platform in the hole and using mechanical equipment to cut, process, connect and tie the steel bars in the hole, it is convenient for the processing of the steel cage and avoids deformation of the steel cage.

[0004] However, some piles are relatively high, and the corresponding steel cages are relatively high. When connecting and tying the steel cages at higher places, scaffolding needs to be set up around the steel cages to facilitate the construction workers' work. After the steel cages are processed, the scaffolding needs to be dismantled and re-erected at the next steel cage. The scaffolding is usually connected by fasteners and is not suitable for hoisting. If it is forced to be hoisted, each connection of the scaffolding needs to be checked after hoisting, which affects the construction efficiency. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a construction frame, a bearing structure and a lifting mechanism. The construction frame is disassembled and then transported to the site for reassembly, which greatly saves transportation space. The first support structure and the second support structure are used to reinforce the first column to form a stable construction frame.

[0017] 2. The present invention is provided with a fixed plate, a lifting structure and a synchronous lifting structure. The synchronous lifting structure controls four winding drums to realize forward or reverse synchronous rotation. The synchronization of the movement of the four winding drums ensures that the lengths of the four cables wound or released per unit time are completely consistent, so that the four corners of the first scaffolding board rise or fall at the same speed, thereby ensuring that the first scaffolding board remains stable during the lifting process, avoiding tilting or shaking caused by asynchronous lifting, and providing a safer and more stable working environment for construction personnel.

Through the cooperation of the central gear and the four driven gears, the four winding drums can realize synchronous rotation, ensuring that the length changes of the four cables are consistent during the winding or releasing process. The worm gear has a self-locking characteristic. When the worm gear stops rotating, a locking state is automatically formed between the worm wheel and the worm gear, preventing the central gear and the four driven gears from rotating by themselves when subjected to external force, thereby ensuring that the four winding drums will not rotate due to external force after the operation stops, thereby realizing that the first scaffolding board can maintain a constant height after being raised to a specified height.

The mounting connection component 122 is arranged at the upper end of the second column 121, and the lifting connection component 122 includes four lifting ears 1221, and the four lifting ears 1221 are respectively arranged on the four second columns 121. The four third supporting structures 123 are respectively arranged between two second columns 121 adjacent to each other in sequence. The third supporting structure 123 includes two third cross braces 1231, and the two ends of the third cross braces 1231 are respectively connected to the two second columns 121. Two second oblique braces 1232 are cross-arranged between the two third cross braces 1231, and the two ends of the second oblique braces 1232 are respectively connected to different ends of the two third cross braces 1231. The fourth supporting structure 124 is arranged on the second column 12 1, the fourth supporting structure 124 includes four third diagonal braces 1241, and the two ends of the third diagonal braces 1241 are respectively connected to the two adjacent third cross braces 1231 in the two adjacent third supporting structures 123; the bearing structure 2 is arranged inside the construction frame 1, and the bearing structure 2 includes a first scaffolding board 21, the first scaffolding board 21 is U-shaped, and the opening of the first scaffolding board 21 faces between the two first columns 111 on which the second supporting structure 113 is installed, and the bearing structure 2 also includes a second scaffolding board 22, and the second scaffolding board 22 is arranged at the opening of the first scaffolding board 21; the lifting mechanism 3 is arranged at the upper end of the construction frame 1, and the lifting mechanism 3 is connected to the four corners of the first scaffolding board 21.

[0034] Since the construction frame 1 has a large structure, it is usually disassembled and transported to the construction site. After arriving at the site, it is first assembled. The four first columns 111 are connected and reinforced by the three first supporting structures 112 and the second supporting structure 113 to form a stable construction frame 11. Then, the four second columns 121 are connected and reinforced by the four third supporting structures 123 and the fourth supporting structure 124 to form a hoisting frame 12. Then, the hoisting equipment is used to connect with the hoisting connection assembly 122 on the hoisting frame 12, and the hoisting frame 12 is stably hoisted to the upper end of the construction frame 11. The hoisting frame 12 and the construction frame 11 are fixed by bolts to make the construction frame 1 a stable overall structure. After the construction frame 1 is assembled, the load-bearing structure 2 and the lifting mechanism 3 are installed on the construction frame 1 to ensure that the three are tightly connected into a whole. At this time, inside the construction frame 1, the first scaffolding board 21 is arranged in a U shape. The opening faces between the two first columns 111 on which the second supporting structure 113 is installed, so that construction materials can enter the interior of the construction frame 1. The second scaffolding board 22 is arranged at the opening of the first scaffolding board 21 to provide a stable working platform for construction personnel. Construction personnel can work around the steel cage. As the steel cage is constructed from bottom to top, the construction position will gradually rise. At this time, the lifting mechanism 3 will simultaneously apply an upward force to the four corners of the first scaffolding board 21 to ensure that the first scaffolding board 21 rises smoothly and avoids tilting. After the construction of the steel cage is completed, the lifting mechanism 3 will smoothly lower the construction personnel on the first scaffolding board 21 to the ground. After the construction personnel evacuate, the lifting mechanism 3 will lift the first scaffolding board 21 upwards, and finally use the lifting equipment to lift the entire construction frame 1 to another steel cage to be processed for the next round of construction, thereby avoiding the need to set up scaffolding at each steel cage to be constructed, thereby improving construction efficiency.

[0035] Reference Figure 5 and Figure 6 As shown: the lifting mechanism 3 includes a fixed plate 31, four lifting structures 32 and a synchronous lifting structure 34; four extension arms 311 extend from the four sides of the fixed plate 31, and the fixed plate 31 is fixedly connected to the upper end of the lifting frame 12; the four lifting structures 32 are respectively arranged on the four extension arms 311, and the lifting structure 32 includes a winding drum 321 and a cable 322, the winding drum 321 is arranged on the fixed plate 31, one end of the cable 322 is connected to the winding drum 321, and the other end of the cable 322 passes through the end of the extension arm 311 and is downwardly connected to a corner of the first scaffolding board 21; the synchronous lifting structure 34 is arranged in the middle of the fixed plate 31, and the synchronous lifting structure 34 is connected to the four winding drums 321.

[0036] Since the construction workers all stand on the first scaffolding board 21 for construction, the first scaffolding board 21 needs to be kept stable during the process of lifting and lowering the first scaffolding board 21 in order to reduce the shaking of the construction workers on the first scaffolding board 21. By setting a fixed plate 31, four lifting structures 32 and a synchronous lifting structure 34, the synchronous lifting structure 34 drives the four winding discs 321 to rotate forward, and the four winding discs 321 start to wind up the cables 322 at the same time, so that the lengths of the four cables 322 wound up in a unit time are kept consistent, ensuring that the four corners of the first scaffolding board 21 rise at the same speed. When the first scaffolding board 21 needs to be lowered, the synchronous lifting structure 34 drives the four winding discs 321 to rotate reversely, and the four winding discs 321 release the cables 322 at the same time, so that the lengths of the four cables 322 released in a unit time are the same, ensuring that the four corners of the first scaffolding board 21 descend at the same speed, thereby ensuring that the first scaffolding board 21 remains stable during the lifting process, avoiding tilting or shaking caused by asynchronous lifting and lowering, and providing a safer and more stable working environment for the construction workers.

[0037] Reference Figure 6 and Figure 7 As shown: the synchronous lifting structure 34 includes a central gear 341, four driven gears 342 and a worm gear driving assembly 343; the central gear 341 is arranged in the middle of the fixed plate 31, and a main rotating shaft 3411 connected to the fixed plate 31 is arranged at the center of the central gear 341, and one end of the main rotating shaft 3411 passes through the bottom of the fixed plate 31; four driven gears 342 are arranged in a circular array around the central gear 341, and the four driven gears 342 correspond to four winding disks 321 respectively, and a driven rotating shaft 3421 connected to the winding disk 321 is arranged in the middle of the driven gear 342; the worm gear driving assembly 343 is arranged at the lower end of the fixed plate 31, and the worm gear driving assembly 343 is connected to the main rotating shaft 3411.

[0038] After the synchronous lifting structure 34 drives the four winding drums 321 to respectively wind up the four cables 322, the winding drums 321 need to be fixed to maintain the height of the first scaffolding board 21 unchanged. By setting the central gear 341, four driven gears 342 and the worm gear transmission structure, the worm gear is connected to the central gear 341 through the main shaft 3411. When it is necessary to drive the four winding drums 321 to rotate synchronously, the construction personnel will operate the worm to rotate, and the rotation of the worm will drive the worm gear to rotate synchronously. The worm gear is connected to the central gear 341 through the main shaft 3411, so the rotation of the worm gear will drive the central gear 341 to rotate synchronously. 41 rotates, the rotation of the central gear 341 will drive the four driven gears 342 around it to rotate synchronously, and then drive the four winding drums 321 to rotate through the driven rotating shaft 3421. By changing the rotation direction of the worm, the cable 322 can be retracted and released. When the construction personnel stop rotating the worm, a self-locking is formed between the worm wheel and the worm, which ensures that the central gear 341 and the four driven gears 342 will not rotate when subjected to external force, and ensures that the four winding drums 321 will not rotate due to external force after the operation is stopped, thereby achieving that the first scaffolding board 21 can maintain a constant height after being lifted to the specified height.

[0039] Reference Figure 5 , Figure 6 and Figure 8 As shown: the lifting mechanism 3 also includes four guide structures 33, which are respectively arranged on four extension arms 311, and the guide structure 33 includes a first pulley group 331 and a second pulley group 332; the first pulley group 331 is arranged at the end of the extension arm 311, the first pulley group 331 includes a first mounting frame 3311 and a plurality of first rollers 3312, the plurality of first rollers 3312 are equidistantly arranged on the first mounting frame 3311, and the cable 322 passes through the plurality of first rollers 3312 in a continuous S shape; the second pulley group 332 is arranged between the first pulley group 331 and the winding drum 321, the second pulley group 332 includes a second mounting frame 3321 and two second rollers 3322, the two second rollers 3322 are flush with the winding drum 321, and the cable 322 passes between the two second rollers 3322.

[0040] The cable 322 passes through a plurality of first rollers 3312 in a continuous S-shaped path, ensuring that the downward force on the cable 322 can be evenly distributed to each first roller 3312, effectively avoiding the failure of one first roller 3312 due to excessive load. As the winding drum 321 winds up the cable 322 more, the cable 322 forms a cable drum inside the winding drum 321. In this process, the cable 322 originally located outside the winding drum 321 may be caused by the gradually increasing The large cable drum is tangent and deviates from its original path, and may even exceed the limit range of the first roller 3312. The second pulley group 332 limits and guides the cable 322 between the first pulley group 331 and the winding drum 321. The cable 322 passes between the two second rollers 3322. The two second rollers 3322 maintain the path of the cable 322 entering the first pulley group 331 unchanged, avoiding the cable 322 from escaping from the limit range of the first roller 3312, thereby ensuring the stable operation of the lifting mechanism 3.

[0041] Reference Figure 5 and Fig. 9 As shown: the lifting mechanism 3 also includes four quick-installation structures 35, and the four quick-installation structures 35 are arranged in a ring array around the fixed plate 31. The quick-installation structure 35 includes a connecting block 351, a connecting plate 352 and a clamping structure 353; the connecting block 351 is connected to the fixed plate 31; one end of the connecting plate 352 is hinged to the connecting block 351; the clamping structure 353 is arranged at the other end of the connecting plate 352, and the clamping structure 353 includes two second clamping plates 3531 and a bidirectional driving structure 3532, the two second clamping plates 3531 are connected to the bidirectional driving structure 3532, and the bidirectional driving structure 3532 is used to drive the two second clamping plates 3531 to clamp the third cross brace rod 1231.

[0042] After the lifting frame 12 is assembled, the construction workers can first install the lifting mechanism 3 on the lifting frame 12, and the construction workers will respectively correspond the four quick installation structures 35 around the fixing plate 31 to the four third supporting structures 123, and then the construction workers will rotate the connecting plate 352 so that the connecting plate 352 can be stably placed on the third cross brace rod 1231. The construction workers operate the two-way driving structure 3532, and the two second clamping plates 3531 will gradually approach and finally clamp on both sides of the third cross brace rod 1231. Since the diameters of the third cross brace rods 1231 in the four third supporting structures 123 remain consistent, the distances required to move the two second clamping plates 3531 in each clamping structure 353 are also exactly the same. When the four clamping structures 353 are successfully connected to the corresponding third cross brace rods 1231, the fixing plate 31 will be stably located in the center position of the lifting frame 12, thereby realizing the quick connection of the lifting mechanism 3 and improving the assembly efficiency.

[0043] Reference Fig. 9and Fig.10 As shown: the quick installation structure 35 also includes a fixing structure 354, which is arranged on the connecting plate 352. The fixing structure 354 includes a fixing hook 3541, an elastic connecting arm 3542 and a connecting hook 3543. The fixing hook 3541 is arranged on the connecting block 351, one end of the elastic connecting arm 3542 is hinged to the connecting plate 352, and the connecting hook 3543 is hinged to the other end of the elastic connecting arm 3542.

[0044] When it is necessary to move the lifting mechanism 3, due to the hinge design between the connecting plate 352 and the connecting block 351, the connecting plate 352 may rotate uncontrollably. When installing the lifting mechanism 3, the positions of the four connecting plates 352 need to be adjusted, which affects the installation efficiency. By setting the fixed structure 354, the construction personnel rotate the connecting plate 352 toward the middle of the fixed plate 31, and then pull the connecting hook 3543. Driven by the connecting hook 3543, the elastic connecting arm 3542 rotates and stretches. The elastic connecting arm 3542 stores elastic potential energy. When the connecting hook 3543 is connected to the fixed hook 3541, the elastic connecting arm 3542 contracts and uses its stored elastic potential energy to apply a pulling force toward the middle of the fixed plate 31 to the connecting plate 352, thereby effectively fixing the connecting plate 352 and preventing it from unnecessary rotation.

[0045] Reference Figure 5 and Fig.11 As shown: the lifting mechanism 3 also includes four second anti-falling structures 36, and the four second anti-falling structures 36 are respectively arranged at the lower ends of the four extension arms 311, and the four second anti-falling structures 36 correspond to the four second columns 121. The second anti-falling structure 36 includes two third clamping plates 361, and the third clamping plates 361 and the extension arms 311 are connected by setting a second connecting shaft 362.

[0046] In the process of installing the fixing plate 31 to the hanging frame 12, the four clamping structures 353 are connected to the hanging frame 12. Therefore, the four clamping structures 353 need to withstand a large downward force. By setting four second anti-falling structures 36, the two third clamping plates 361 in the second anti-falling structures 36 are stored directly under the extension arm 311, which effectively avoids unnecessary contact between the two third clamping plates 361 and the hanging frame 12, ensuring that the fixing plate 31 can be smoothly placed in the hanging frame 12. When the four clamping structures 353 are connected to the hanging frame 12, Afterwards, the two third clamping plates 361 rotate around their respective second connecting shafts 362 until the two third clamping plates 361 are respectively located on both sides of the second column 121 corresponding to the second anti-fall structure 36, and the construction workers use bolts to fasten the two third clamping plates 361 on both sides of the second column 121. Friction will be generated between the two third clamping plates 361 and the second column 121, and the friction can provide a stable upward supporting force for the fixed plate 31, thereby effectively preventing the risk of the fixed plate 31 sliding down or falling off due to excessive force on the clamping structure 353.

[0047] Reference Figure 3 and Fig.12 As shown: the bearing structure 2 also includes four first anti-falling structures 23, and the four first anti-falling structures 23 are respectively arranged at the lower ends of the four corners of the first scaffolding board 21. The first anti-falling structure 23 includes two first clamping plates 231, and one end of the first clamping plate 231 is provided with a first connecting shaft 232, and one end of the first connecting shaft 232 is connected to the first scaffolding board 21.

[0048] The first scaffolding board 21 is closely connected to the synchronous lifting structure 34 through four lifting structures 32. The synchronous lifting structure 34 can accurately fix the height of the first scaffolding board 21 by relying on the worm gear drive assembly 343 to ensure the stability of the first scaffolding board 21. However, when construction workers walk on the first scaffolding board 21, a downward impact force will be generated. This impact force may have a significant impact on the meshing of the central gear 341 and the driven gear 342. By respectively arranging the four first anti-falling structures 23 at the four corners of the first scaffolding board 21, after the lifting mechanism 3 completes the height adjustment, the construction workers can The worker rotates the two first clamping plates 231 to rotate the first clamping plates 231 around the axis of the first connecting shaft 232 to one side of the first column 111, and then uses bolts to fasten the two first clamping plates 231 to both sides of the first column 111. By increasing the contact area and friction between the first clamping plates 231 and the first column 111, additional upward supporting force is provided for the first scaffolding board 21, thereby effectively sharing the impact force generated by the construction workers when walking, reducing the wear on the center gear 341 and the driven gear 342, and extending the service life of the synchronous lifting structure 34.

[0049] Reference Fig.12 As shown, the first anti-falling structure 23 includes a moving plate 233 , which is slidably disposed on the first scaffolding plate 21 , and the moving plate 233 is connected to the first connecting shaft 232 .

[0050] The first supporting structure 112 is connected to the first column 111. At a position near the connection between the first column 111 and the first diagonal support rod 1122, the first clamping plate 231 cannot rotate around the first connecting axis 232. By setting a movable plate 233, in the initial state, the movable plate 233 drives the two first clamping plates 231 to be retracted to the bottom of the first scaffolding board 21. When the two first clamping plates 231 need to be fastened to the position where the first diagonal support rod 1122 is connected on the first column 111, the construction personnel first rotate the two first clamping plates 231 to make the opening size of the two first clamping plates 231 adapt to the first column 111, and then push the movable plate 233. The movable plate 233 drives the two first clamping plates 231 to move toward the first column 111 and wrap the first column 111, so that the first scaffolding board 21 can be supported at a position near the connection between the first column 111 and the first diagonal support rod 1122.

[0051] A construction method, applied to the above-mentioned large-diameter bored pile reinforcement cage construction equipment, comprises the following steps: S1, first install the bearing structure 2 and the lifting mechanism 3 on the construction frame 1; S2, then hoist the construction frame 1 as a whole to the upper end of the steel cage to be constructed, and cover the construction frame 1 around the steel cage to be constructed; S3, the materials used for construction are fed into the construction frame 1 through the space between the two first columns 111 of the second support structure 113; S4, the construction workers stand on the first scaffolding board 21, and as the height of the steel cage increases, the lifting mechanism 3 raises the height of the first scaffolding board 21, so that the construction workers can continue to work at a higher height; S5, after the construction is completed, the lifting mechanism 3 lowers the construction workers to the ground, then hoists the construction frame 1 upward as a whole and moves it to one side of the steel cage.
