Description

Technical Field

[0001] This invention relates to the field of steel cage manufacturing, and in particular to a modular steel cage manufacturing device and its usage method. Background Technology

[0002] A reinforcing cage is a structure used in building construction to reinforce concrete column or strip members. It is typically made of tied reinforcing bars and is cage-shaped. Its main function is to provide tensile strength, increasing the load-bearing capacity and tensile properties of the member. In pile foundation engineering, the reinforcing cage is placed in the pile hole and poured together with the concrete. As an important component of the pile foundation structure, it improves the load-bearing capacity and stability of the pile foundation. When fabricating and installing reinforcing cages, attention must be paid to their dimensions, shape, materials, and welding quality to ensure they meet design requirements and construction specifications.

[0003] When carrying out external power supply projects for traction substations, bored piles are often used as foundations in mountainous terrain. However, the construction of bored piles requires the fabrication of steel cages within the excavated foundation pit. This poses risks to workers' safety, including poisoning, suffocation, falls from heights, and being struck by falling objects. Therefore, we propose a split-type steel cage fabrication device for fabricating steel cages outside the foundation pit. Summary of the Invention

Vertically insert the main bars of the first set of split-type rebar cages into the clamping member, which clamps the main bars. Align the second set of split-type rebar cages with the fixed split-type rebar cages and weld the two sets of split-type rebar cages together. Rotate the rotating ring to retract the clamping member, thus removing it from the first set of split-type rebar cages.

Then, the modular rebar cage is connected outside the foundation pit using the modular rebar cage fabrication device. This enables unmanned operation throughout the entire rebar cage fabrication process, avoiding construction risks such as gas poisoning, personnel falls, and collapse injuries, thus protecting the lives of workers. At the same time, the larger space outside the foundation pit allows for faster fabrication, and the spacing and straightness of the rebars are easy to control, resulting in high precision in foundation construction.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0039] Please see Figures 1 to 9This invention provides a technical solution: a split-type rebar cage manufacturing device, including a base 1, a support member 2 fixedly installed on the upper end of the base 1, a positioning ring 3 fixedly connected to the upper end of the support member 2, and multiple sets of transverse moving members 4 movably arranged inside the positioning ring 3. The transverse moving members 4 are configured as transverse rod-shaped members, and external threads are provided on the outer surface of the transverse moving members 4. Clamping members 9 are fixedly connected to the inner side of each transverse moving member 4. Each clamping member 9 is a U-shaped member composed of two sets of arc-shaped semicircular members. Contacts 10 are fixedly provided at the ends of the arc-shaped semicircular members. The clamping members 9 are used to clamp the main bars of the split-type rebar cage. The contacts 10 facilitate the increase of the friction coefficient during clamping, making the clamping more secure. At the same time, the U-shaped opening facilitates the movement of the clamping members 9 with the transverse moving members 4, so that the split-type rebar cage can be lowered into the foundation pit.

[0040] An inner ring expansion ring unit 5 is movably arranged in the middle of the inner side of the transverse component 4. The inner ring expansion ring unit 5 is set as an arc-shaped plate. The arc-shaped inner ring expansion ring units 5 can form a ring. An expansion groove 6 is set on one side of the inner ring expansion ring unit 5. The expansion groove 6 is set as an arc-shaped groove. An expansion component 7 is integrally formed on the other side of the inner ring expansion ring unit 5. The expansion component 7 is set as an arc-shaped plate. The size of the expansion component 7 is adapted to the expansion groove 6. The expansion component 7 is movably located in the expansion groove 6 of the adjacent inner ring expansion ring unit 5. Multiple sets of inner ring expansion ring units 5 can be connected through the expansion component 7 and the expansion groove 6 to form a ring for the fabrication of a split steel cage. An extrusion elastic component 8 is fixedly installed on one side of the inner ring expansion ring unit 5. The extrusion elastic component 8 is fixedly connected to the inner wall of the positioning ring 3 on one side. The extrusion elastic component 8 is mainly used to push the inner ring expansion ring unit 5 inward.

[0041] Meanwhile, a toggle transmission component 11 is screwed onto the outside of the transverse component 4. The outside of the toggle transmission component 11 is set as an annular inclined surface. A ring component with a T-shaped cross section is set on one side of the toggle transmission component 11. The ring component is movably located inside the positioning ring 3. The screw connection between the toggle transmission component 11 and the transverse component 4 can facilitate the lateral movement of the clamping component 9, so that the clamping component 9 moves outward and no longer clamps the split steel cage, so as to move the split steel cage down into the foundation pit.

[0042] Since there are multiple sets of transverse moving parts 4, if each actuating transmission part 11 is rotated to move the clamping part 9, the overall time required would be too long. Therefore, a fixing ring 12 is fixedly installed on the outside of the positioning ring 3. Inside the fixing ring 12, a transmission part 13 is movably arranged corresponding to the actuating transmission part 11. The movably arranged transmission part 13 can rotate within the fixing ring 12. The bottom of each transmission part 13 passes through the fixing ring 12 and extends outward. A transmission wheel 14 is fixedly installed on the bottom of each transmission part 13. The transmission wheel 14 is configured as a bevel gear, with an annular inclined surface at the upper end. The outer side of the actuating transmission component 11 is provided with bevel teeth 15 corresponding to the transmission wheel 14. The transmission wheel 14 meshes with the actuating transmission component 11 through the bevel teeth 15. The meshing of the transmission wheel 14 with the actuating transmission component 11 facilitates the rotation of the transmission component 13 while driving the actuating transmission component 11, thereby allowing the clamping component 9 to move outward accordingly. The upper end of the transmission component 13 is fixedly connected to a transmission wheel 16, which is configured as a gear.

[0043] Meanwhile, a rotating ring 17 is movably provided at the upper end of the fixed ring 12. The rotating ring 17 is an L-shaped annular structure. The inner side of the rotating ring 17 is movably connected to the positioning ring 3. The rotating ring 17 is movably sleeved on the outer side of the fixed ring 12 to facilitate rotation. The vertical plate-shaped inner wall of the rotating ring 17 is provided with multiple sets of teeth 18 at equal intervals. The rotating ring 17 meshes with the transmission wheel 16 through the teeth 18. When the rotating ring 17 rotates, it drives all the transmission wheels 16 to rotate through the teeth 18, which can simultaneously drive all the clamping parts 9 to expand outward, so that the clamping parts 9 can be moved quickly when the split steel cage is moved down.

[0044] Because the rotating ring 17 may rotate when the clamping member 9 clamps the main reinforcement of the split steel cage, causing the clamping member 9 to shrink and separate from the main reinforcement of the split steel cage, a limiting member 19 is movably installed inside the transverse plate of the rotating ring 17. The limiting member 19 is a transverse rod-shaped member, which facilitates the movement of the rotating ring 17. A moving tooth 20 is fixedly connected to the outer side of the middle of the limiting member 19. The moving tooth 20 is a transverse tooth with a trapezoidal cross section, which facilitates the rotation of the limiting member 19. A rotating groove 21 is provided inside the transverse plate of the rotating ring 17 corresponding to the moving tooth 20. The bottom of the rotating groove 21 penetrates the rotating ring 17, and the penetrating part at the bottom of the rotating groove 21 facilitates the extension of the moving tooth 20 to its outer side. After the moving tooth 20 rotates and extends to the bottom of the rotating groove 21, the side of the moving tooth 20 fits against the side wall of the rotating groove 21, so that the limiting member 19 is limited. A side plate 22 is fixedly installed on the outer side of the middle section of the limiting member 19. The side plate 22 is set as an annular plate. A reset elastic member 23 is fixedly connected to the outer side of the side plate 22. The side plate 22 and the reset elastic member 23 cooperate to reset the limiting member 19. At the same time, after the moving tooth 20 rotates and extends out of the rotating groove 21, it is easy to fit the moving tooth 20 against the side wall of the rotating groove 21. The outer side of the limiting member 19 passes through the rotating ring 17 and extends to the outside. A pull member 24 is fixedly connected to the outer end of the limiting member 19. The pull member 24 is set as a bead structure. The bead structure of the pull member 24 can be easily gripped when rotating the rotating ring 17.

[0045] Due to prolonged outdoor use, the meshing points within the overall device are prone to corrosion, causing operational inconvenience. Therefore, multiple sets of rotating components 26 are movably arranged on the upper end of the fixed ring 12 corresponding to the transmission component 13. The rotating components 26 are vertical threaded rod-shaped components, and multiple sets of actuating components 27 are fixedly connected in a ring at equal intervals on the upper end of the rotating components 26. The actuating components 27 are arranged in a star-shaped structure. When the limiting component 19 drives the actuating teeth 20 to rotate, the actuating components 27 drive the rotating components 26 to rotate along with the actuating teeth 20. The outer sides are all threaded with pressing parts 28. The screw connection between the rotating part 26 and the pressing parts 28 can facilitate the downward movement of the pressing parts 28. The pressing parts 28 are rectangular block parts. The inner sides of the pressing parts 28 are all fixedly connected with sliding parts 29. The sliding parts 29 are T-shaped block parts. The outer sides of the positioning rings 3 are all provided with sliding grooves 30 corresponding to the sliding parts 29. The sliding grooves 30 are T-shaped vertical grooves. The sliding parts 29 are all located in the sliding grooves 30. The pressing parts 28 move downward along the sliding parts 29 through the sliding grooves 30 to prevent the pressing parts 28 from shifting.

[0046] Meanwhile, each of the pressing parts 28 is equipped with an oil storage part 31 at its bottom. The oil storage part 31 is designed as an oil sponge that absorbs lubricating oil. When the pressing part 28 moves down and squeezes the oil storage part 31, the lubricating oil can be squeezed out and come to the meshing point between the transmission wheel 16 and the tooth 18 for lubrication. At the same time, the transmission part 13 is provided with a downward flow groove 32 on the outside corresponding to the oil storage part 31. The downward flow groove 32 is a vertical groove that can allow the lubricating oil to seep out, so that the lubricating oil comes to the meshing point between the transmission wheel 14 and the bevel tooth 15, thus preventing rust.

[0047] A method for using a split-type rebar cage fabrication device includes the following steps:

[0048] S1: First, divide the steel cage according to its height, and then make a split steel cage according to the divided height.

[0049] S2: Place and fix the split-type rebar cage fabrication device at the pit opening. Vertically insert the main reinforcing bars of the first set of split-type rebar cages into the clamping member, which clamps the main reinforcing bars. Align the second set of split-type rebar cages with the fixed split-type rebar cages and weld the two sets of split-type rebar cages together. Pull the limiting member 19 outwards, causing the limiting member 19 to align the actuating tooth 20 with the rotating groove 21. Rotate the limiting member 19, causing the actuating tooth 20 to leave the rotating groove 21 and come to the bottom of the rotating ring 17. Pinch the limiting member 19 and drive the rotating ring to rotate. Through the meshing of the transmission wheel 14 and the bevel tooth 15, the clamping member retracts and stops clamping the first set of rebar cages. For a split-type rebar cage, two sets of split-type rebar cages are lowered, allowing the first set of split-type rebar cages to enter the foundation pit. At the same time, the actuating tooth 20 pushes the actuating component 27, causing the rotating component 26 to rotate. The pressing component 28 moves down to add oil storage component 31, allowing lubricating oil to seep out from the oil storage component 31. This lubricates the meshing points of the transmission wheel 16 and the teeth 18, and the transmission wheel 14 and the bevel teeth 15, preventing rust. When the main reinforcement of the second set of split-type rebar cages is aligned with the clamping component, the limiting component 19 is reversed, causing the rotating ring to reverse, so that the clamping component clamps the second set of split-type rebar cages. Then, the third set is placed on top of the second set of rebar cages. The above operation is repeated until the rebar cage is completed.
