Description

Technical Field

[0001] This invention relates to the technical field of bridge pile foundation steel cage processing equipment, specifically to a bridge pile foundation steel cage fabrication device. Background Technology

[0002] The main function of the reinforcing cage is similar to that of the longitudinal reinforcement in a column, primarily resisting tension. Concrete has high compressive strength but very low tensile strength. It restrains the concrete of the pile, enabling it to withstand a certain axial tensile force. During the construction of bridges, culverts, or high-rise buildings, foundation piling may be required. This is done using machine-drilled holes or water-jet drills, ensuring the hole depth meets design requirements. The reinforcing cage is then lowered into the pile hole, and a guide pipe is inserted for concrete pouring.

[0003] The on-site processing of the reinforcing cage is mainly as follows: First, multiple reinforcing rings are positioned. Then, two workers lift a main reinforcing bar from both ends and place the main reinforcing bar close to the multiple reinforcing rings. Other workers use welding equipment to weld the main reinforcing bar onto the reinforcing rings. This process is repeated to complete the welding and positioning of each main reinforcing bar. Finally, the spiral reinforcing bar is spirally welded to the outer wall of the main reinforcing bar to complete the fabrication of the reinforcing cage.

[0004] The above process requires a large number of workers, the positioning accuracy of the main reinforcement bars is not high, and the processing efficiency is low. Although there are currently machines that can actively weld the main reinforcement bars, the overall size of the equipment is large, which is not convenient for the construction site. Furthermore, the steel cage needs to be pulled out from the end after processing, resulting in a long overall length of the equipment and a large footprint. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device for fabricating steel cages for bridge pile foundations, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A bridge pile foundation steel cage fabrication device includes multiple sets of side support components. A clamping mechanism is installed on the inner wall of the side support components. The clamping mechanism includes an upper clamping component and a lower clamping component. End positioning components are installed at both ends of the multiple sets of support components. Each set of upper clamping components and lower clamping components is located between two sets of end positioning components. The upper clamping components and lower clamping components are used to externally clamp and position the steel cage reinforcing ring located in the middle. The end positioning components are used to internally clamp and position the steel cage reinforcing ring located at the end.

[0008] Two sets of end positioning components are installed on the opposite side of the side support components.

[0041] 1. The upper and lower clamping components can be used to clamp and position the reinforcing ring from the upper and lower sides, which facilitates the welding of the two sets of main ribs and achieves external clamping.

[0042] 2. First, weld two sets of main stiffeners to achieve the pre-positioning of each reinforcing ring. Then, the upper and lower clamping components disengage, and the end positioning components can drive the pre-positioned reinforcing rings to rotate. The upper and lower clamping components will not affect the automatic welding of the remaining main stiffeners, so that the subsequent main stiffeners can be welded smoothly.

[0043] 3. After the steel cage is processed, the lower clamping component can lift the steel cage from the bottom, so that the end positioning components at both ends can be withdrawn in the normal axial direction; after the end positioning components are withdrawn, the upper clamping component rotates upward, and the crane can lift and remove the processed steel cage, realizing vertical material feeding, effectively reducing the footprint of the steel cage manufacturing device, and making material feeding simpler and more efficient.

[0060] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] Example 1

[0062] To address the technical problems in the background section, the following bridge pile foundation reinforcement cage fabrication device is provided:

[0063] Combination Figures 1-12As shown, the present invention provides a bridge pile foundation rebar cage fabrication device, comprising multiple sets of side support components 6, a clamping mechanism installed on the inner wall of the side support components 6, the clamping mechanism including an upper clamping component 7 and a lower clamping component 8, end positioning components 4 installed at both ends of the multiple sets of support components, each set of upper clamping components 7 and lower clamping components 8 being positioned between two sets of end positioning components 4, the upper clamping components 7 and lower clamping components 8 being used to externally clamp and position the rebar cage reinforcing ring 9a located in the middle, the end positioning components 4 being used to internally clamp and position the rebar cage reinforcing ring 9a located at the end, a spiral conveying component 3 being installed on the other side of the two sets of end positioning components 4 away from the side support components 6, the spiral conveying component 3 being used to convey the spiral bars of the rebar cage to the welded main reinforcing bars 9b; multiple sets of tilting feeding components 2 being installed on the outer side of the spiral conveying component 3, a feeding platform 5 being installed on the outer side of the tilting feeding component 2; a welding head 28 being installed at the inner end of the tilting feeding component 2.

[0064] The device includes the following states: In the first state, the reinforcing ring 9a in the middle of the reinforcing cage is installed in the clamping mechanism, and the reinforcing ring 9a at the end of the reinforcing cage is installed in the end positioning assembly 4; In the second state, the reinforcing ring 9a is pre-positioned: the flipping feeding assembly 2 conveys the first main reinforcing bar 9b to fit against each group of reinforcing rings 9a, and the welding head 28 welds the first main reinforcing bar 9b to the side wall of each group of reinforcing rings 9a; the upper clamping assembly 7 is lifted, and the lower clamping assembly 8 and the end positioning assembly 4 drive each group of reinforcing rings 9a to rotate counterclockwise by 180°, and the flipping feeding assembly 2 and the welding head 28 weld the second main reinforcing bar 9b to the side wall of each group of reinforcing rings 9a, and the two main reinforcing bars 9b are completed. In the first state, the upper clamping component 7 and the lower clamping component 8 are disengaged, and the end positioning component 4 drives the end reinforcing ring 9a to rotate gradually. The flipping feeding component 2 and the welding head 28 work together to weld the remaining main reinforcing bars 9b in an annular array to the side wall of each group of reinforcing rings 9a. In the second state, the spiral conveying component 3 spirally winds the spiral reinforcing bars around the outer wall of the main reinforcing bars 9b. The spiral winding points of the spiral reinforcing bars are manually welded to complete the fabrication of the reinforcing cage. In the third state, the upper clamping component 7 rotates upward, the lower clamping component 8 lifts the reinforcing cage, and the end positioning component 4 moves outward and disengages from the reinforcing cage, allowing the reinforcing cage to be lifted directly upward.

[0065] In the above scheme:

[0066] 1. The upper and lower clamping components can be used to clamp and position the reinforcing ring from the upper and lower sides, which facilitates the welding of the two sets of main ribs and achieves external clamping.

[0067] 2. First, weld two sets of main stiffeners to achieve the pre-positioning of each reinforcing ring. Then, the upper and lower clamping components disengage, and the end positioning components can drive the pre-positioned reinforcing rings to rotate. The upper and lower clamping components will not affect the automatic welding of the remaining main stiffeners, so that the subsequent main stiffeners can be welded smoothly.

[0068] 3. After the steel cage is processed, the lower clamping component can lift the steel cage from the bottom, so that the end positioning components at both ends can be withdrawn in the normal axial direction; after the end positioning components are withdrawn, the upper clamping component rotates upward, and the crane can lift and remove the processed steel cage, realizing vertical material feeding, effectively reducing the footprint of the steel cage manufacturing device, and making material feeding simpler and more efficient.

[0069] 4. The design of the flip-feed component can achieve the following effects: 4.1. It can automatically flip and lift the main ribs to the feeding position; 4.2. It can automatically weld the main ribs one by one onto the reinforcing ring.

[0070] In this embodiment, the feeding platform 5 is equipped with a guiding assembly 1 at both ends. The guiding assembly 1 includes a first upright plate 11 and a side plate 12. The side plate 12 is symmetrically arranged on both sides of the feeding platform 5. The outer wall of the side plate 12 is equipped with a first adjusting screw 14 and a guide rod 13. The first adjusting screw 14 and the guide rod 13 both pass through the top end of the first upright plate 11.

[0071] In the above scheme, the side plates at both ends can constrain and guide the main ribs, so that the main ribs can stably enter the feeding position of the pushing and feeding component;

[0072] The position of the side plate can be adjusted by rotating the first adjusting screw, thereby adapting to the feeding needs of main ribs of different lengths. The guide rod can guide the translation of the side plate.

[0073] In this embodiment, the flipping and feeding assembly 2 includes a first base 21, a movable plate 29 is slidably installed inside the first base 21, and a first drive rod 22 inside the first base 21 drives the movable plate 29 to translate. The side cross-section of the movable plate 29 is shaped like a "7". An end plate 291 is vertically provided at the top end of the movable plate 29. A lifting assembly 27 is installed on the top of the outer wall of the end plate 291, and a welding head 28 is installed on the bottom of the outer wall. A horizontal toothed plate 26 is fixed on the side wall of the movable plate 29. The top of the toothed plate 26 is meshed with a central gear 25. The central gear 25 is provided on the side wall of the base through a second vertical plate 23. A lifting rod 24 is connected at the center of the central gear 25. The lifting rod 24 extends horizontally outward, and a support cover 241 is provided at the end of the lifting rod 24 to support the main rib 9b. The flipping and feeding assembly 2 includes the following stages during feeding:

[0074] In the first stage, the first drive rod 22 retracts to drive the movable plate 29 and the lifting assembly 27 to move outward, and the toothed plate 26 drives the central gear 25 to rotate to drive the lifting rod 24 to rotate upward. The lifting rod 24 automatically feeds the main rib 9b into the lifting assembly 27. In the second stage, the first drive rod 22 extends to drive the movable plate 29 to reset, so that the lifting assembly 27 and the main rib 9b above it are close to the reinforcing ring 9a. In the third stage, the welding head 28 welds the main rib 9b to each reinforcing ring 9a from below.

[0075] In the above scheme,

[0076] When the first drive rod moves the movable plate outward, it can simultaneously move the lifting component outward, so that the top of the lifting component is exposed, which is convenient for loading. When the lifting component moves outward, it can drive the lifting rod to flip upward through the central gear, so that the main rib can be automatically transferred into the lifting component.

[0077] When the first drive rod moves the movable plate inward, it can drive the lifting rod to rotate outward and reset, which facilitates the feeding of the main rib, lifts the component to move inward and reset, and realizes the fit between the main rib and the reinforcing ring.

[0078] In this embodiment, the lifting assembly 27 includes a main support plate 271. A second drive rod 272 is provided at the outer end of the bottom surface of the main support plate 271. The second drive rod 272 is fixed to the outer wall of the end plate 291. The main support plate 271 is horizontally arranged. A first back plate 2711 is provided at the inner end of the bottom surface of the main support plate 271, and a second back plate 2712 is provided at the outer end of the surface. An inner stop block 277 is vertically slidably installed at the inner end of the surface of the main support plate 271. The outer wall of the inner stop block 277 is arc-shaped. A third spring rod 278 is installed between the bottom surface of the inner stop block 277 and the first back plate 2711. An outer abutment assembly is vertically slidably installed on the surface of the main support plate 271. The outer abutment assembly is connected to the second back plate 2712. The welding head 28 is located on the bottom side of the main support plate 271.

[0079] In this embodiment, the external contact assembly includes an outer baffle 273, which is shaped like the number 7. A second spring rod 276 is installed between the outer wall of the outer baffle 273 and the second back plate 2712. A first spring rod 274 is vertically installed inside the outer baffle 273, and a pressure block 275 is installed at the bottom end of the first spring rod 274. In the first stage, the movable plate 29 moves outward, and the main rib 9b is placed between the inner baffle 277 and the pressure block 275 by the support cover 241. In the second stage, the movable plate 29 moves inward, and when the reinforcing ring 9a abuts against the main rib 9b, the main rib 9b is pushed in the opposite direction. The outer baffle 273 retracts, and the pressure block 275 retracts and presses down to position the main rib 9b. In the third stage, the welding head 28 welds the main rib 9b to each set of reinforcing rings 9a.

[0080] In the above scheme,

[0081] 1. During the flipping feeding process, the main rib is placed between the inner stop block and the pressure block to achieve the pre-positioning of the main rib;

[0082] 2. When the movable plate moves inward, the main ribs fit against and compress the reinforcing ring. In this way, the main ribs can press against the outer baffle and the pressure block in the opposite direction. The pressure block can then press down to position the main ribs, ensuring the vertical stability of the welding. The outer baffle can then stop and position the main ribs from the outside, ensuring the lateral stability of the welding.

[0083] 3. After welding is completed, since the inner stop block is placed inside the welded main rib, in order to allow the lifting component to move outward, the inner stop block is designed to be an elastic structure. When the lifting component moves outward, the main rib squeezes the inner stop block, causing the inner stop block to press down and contract. In this way, the lifting component can be moved out normally.

[0084] In this embodiment, the side support assembly 6 includes a side base 61 and a first bidirectional screw guide rail 62. The side base 61 is L-shaped, and the inner wall of the side base 61 is provided with the first bidirectional screw guide rail 62. The inner wall of the first bidirectional screw guide rail 62 is vertically connected to the upper clamping assembly 7 and the lower clamping assembly 8. The upper clamping assembly 7 includes a second bidirectional screw guide rail 71 and a first connecting seat 72. The first connecting seat 72 is threaded into the first bidirectional screw guide rail 62, and the inner end of the first connecting seat 72 is rotatably connected to the second bidirectional screw guide rail 62. A rotating motor 73 is installed at the rotatable connection of the rail 71. Upper clamping wheels 74 are symmetrically installed at the bottom of the second bidirectional screw guide rail 71. The lower clamping assembly 8 includes a third bidirectional screw guide rail 81 and a second connecting seat 82. The second connecting seat 82 is threaded into the first bidirectional screw guide rail 62. The outer end of the second connecting seat 82 is fixedly connected to the third bidirectional screw guide rail 81. Lower clamping wheels 83 are symmetrically installed on the surface of the third bidirectional screw guide rail 81. A reinforcing ring 9a is placed between the upper clamping wheel 74 and the lower clamping wheel 83.

[0085] In the above scheme,

[0086] 1. The second bidirectional screw guide rail can drive the opening and closing of two sets of upper clamping wheels, and the third bidirectional screw guide rail can drive the opening and closing of two sets of lower clamping wheels, thereby adapting to the support needs of reinforcing rings of different sizes;

[0087] 2. The flip motor can drive the second bidirectional screw guide rail to flip upward and open.

[0088] 3. The first bidirectional screw guide rail can drive the upper and lower clamping wheels to open and close, meeting the processing requirements of different states.

[0090] When welding the main stiffener to the reinforcing ring, dust and impurities are present on both the reinforcing ring and the main stiffener, affecting the welding effect. To solve this problem, the following solution is proposed:

[0091] In this embodiment, a grinding component 9 is installed on the inner end surface of the third bidirectional screw guide rail 81. The grinding component 9 includes a support plate 91. A sixth drive rod 92 is vertically slidably installed on the surface of the support plate 91. The top end of the sixth drive rod 92 is connected to a lower support 93. The top end of the lower support is rotatably connected to a flip seat 94. A grinding seat 95 is installed on the top of the flip seat 94. A grinding brush 96 is installed on the top of the grinding seat 95.

[0092] In the second stage, the movable plate 29 moves inward once, and the grinding brush 96 is placed horizontally between the main rib 9b and the reinforcing ring 9a. The grinding brush 96 grinds the welding surfaces of the main rib 9b and the reinforcing ring 9a at the same time. After grinding, the grinding brush 96 is lowered and adjusted to a vertical position. The movable plate 29 moves inward a second time so that the main rib 9b and the reinforcing ring 9a are in contact, so that the welding head 28 can be welded. In the third stage, the main rib 9b and the reinforcing ring 9a are welded. The vertical grinding brush 96 is in contact with the welding point and the grinding brush 96 cleans the welding slag at the welding point.

[0093] In the above scheme,

[0094] A grinding brush is installed on the third bidirectional screw guide rail. The grinding brush, which is in a horizontal state, can simultaneously grind the weld points of the reinforcing ring and the main rib when the main rib is just put into the supporting component, thereby improving the subsequent welding effect.

[0095] The welding head welds the reinforcing ring and the main rib together from below. In this way, the grinding brush located below can be turned into a vertical position. The vertical grinding brush can grind the weld point, remove the welding slag, and make the welding effect better.

[0096] In this embodiment, the polishing brush 96 includes a middle box 961, with bristles 963 embedded in an annular array on the outer wall of the middle box 961. Vent holes 962 are provided between adjacent bristles 963. A drive shaft 964 rotatably passes through the center of the top surface of the polishing base 95. The outer end of the drive shaft 964 is connected to the middle box 961, and the inner end is connected to the air supply pump 966 through a movable joint. A driven gear 9641 is provided on the outer wall of the drive shaft 964. The driven gear 9641 meshes with the driving gear 9651, and the driving gear 9651 is connected to the polishing motor 965.

[0097] In the second stage, the protective gas is discharged from the vertically positioned middle box 961 to the welding point;

[0098] In the third stage, the vertically positioned middle box 961 discharges gas to purge and clean the welding slag underneath.

[0099] In the above scheme,

[0100] Vent holes are provided on the outer wall of the middle box. The vertically arranged vent holes can discharge inert protective gas to the welding position during welding, so that the welding is in the protective gas, reducing the generation of welding slag, and blowing away the welding fumes at the same time. During cleaning, the discharged gas can blow away the welding slag.

[0101] In this embodiment, the end positioning component 4 includes a second base 41, a third upright plate 43 is vertically slidably mounted on the surface of the second base 41, a fourth drive rod 42 for driving the third upright plate 43 to translate is installed inside the second base 41, a rotating plate 44 is rotatably mounted on the top of the third upright plate 43, a rectangular block 45 is mounted on the inner wall of the rotating plate 44, a fifth drive rod 46 is vertically provided on each of the four sides of the rectangular block 45, an inner push plate 47 is provided at the outer end of the fifth drive rod 46, a mating groove 471 is opened on the outer wall of the inner push plate 47, and a reinforcing ring 9a is embedded in the mating groove 471.

[0102] In the above scheme,

[0103] The fourth drive rod can drive the third upright plate to move in and out, meeting the exit requirements of the end positioning component; the rotating plate can drive the rectangular block to rotate when it rotates; the fifth drive rod can adjust the extension length of the inner push plate, thereby adapting to the installation and positioning needs of reinforcing rings with different inner diameters.

[0104] In this embodiment, the spiral conveying assembly 3 includes a movable guide rail 31, a first movable block 32 is slidably installed inside the movable guide rail 31, a take-up wheel 33 is installed on the bottom of the inner wall of the first movable block 32, a spiral rib is wound on the outer wall of the take-up wheel 33, a top plate 34 is provided at the top of the first movable block 32, a second movable block 36 is slidably installed on the surface of the top plate 34, a third drive rod 35 is installed on the outer wall of the second movable block 36, a guide roller 39, a shearing plate 38 and a support block 37 are installed on the bottom of the inner wall of the second movable block 36, and a fourth spring rod 371 is installed on the back of the support block 37.

[0105] In the above scheme, the spiral ribs are wound and stored on the take-up roller. The spiral ribs pass through the guide roller and the shearing plate to the inside of the abutment block. The abutment block brings the spiral ribs close to the main ribs. The worker can first weld the ends of the spiral ribs to the main ribs. Then, the first moving block moves along the moving guide rail and the reinforcing ring rotates, so that the spiral ribs are spirally wound onto the main ribs. After winding is completed, the shearing plate cuts the spiral ribs. At the same time, the worker welds the contact points between each spiral rib and the main rib.
