Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for T-beam preparation, and relates to a lifting device for T-beam reinforcement cages. Background Technology

[0002] The prefabrication of T-beams requires the processing and fabrication of the T-beam reinforcement cage. After the cage is fabricated, it needs to be transported to the mold. The conventional practice is to fabricate the steel cages for the top plate and the lower vertical plate separately and then transport them to the mold for final assembly. However, the mold space is small and it is not easy to assemble. After the complete T-beam reinforcement cage is assembled outside, it is prone to deformation due to the large area and weight of the T-beam reinforcement skeleton. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a lifting tool for T-beam steel cages, which will not deform during lifting and is easy to manufacture.

[0004] The technical solution adopted by this utility model is as follows: A lifting device for T-beam steel cages includes a truss, a chain, and chain locks. A fixed seat is symmetrically fixedly connected to the top side of the truss. A hanging hole for attaching a crane hook is provided at the center of the top side of the fixed seat. Two chain locks are provided at both ends of each chain. Multiple chains are used and evenly arranged along the length of the truss. Each chain group uses four chains. The middle part of each chain is fixedly connected to the truss. Each chain lock is attached to the steel bars of the T-beam steel cage.

[0005] Furthermore, the aforementioned truss includes a bottom strip frame and a top longitudinal beam. The top longitudinal beam is parallel to the length direction of the bottom strip frame. The top longitudinal beam and the bottom strip frame are fixedly connected by multiple sets of figure-eight diagonal braces arranged symmetrically on the front and back sides. Multiple horizontal beams are fixedly connected evenly in the middle of the bottom strip frame. The lower ends of two adjacent sets of figure-eight diagonal braces are fixedly connected to both sides of a horizontal beam.

[0006] Furthermore, the aforementioned fixed base includes two inclined beams and a connecting base. One end of the two inclined beams is symmetrically fixedly connected to both sides of the connecting base, and the other end of the two inclined beams is fixedly connected to two support bases. The support bases are fixedly connected to the top longitudinal beam. The connecting base includes a T-shaped square tube base, a base plate, side plates, and lifting lugs. The lower end of the T-shaped square tube base is fixedly connected to the base plate. Two side plates are used, which are respectively fixedly connected to both sides of the vertical beam of the T-shaped square tube base and fixedly connected to the horizontal beam of the T-shaped square tube base and the base plate. The lifting lugs are fixedly connected to the top of the horizontal beam of the T-shaped square tube base and are consistent with its length direction. Multiple pairs of reinforcing ribs are provided on both sides of the lifting lugs and fixedly connected to the top of the horizontal beam.

[0007] Furthermore, the truss is constructed by connecting multiple sections, with the bottom strip frame and top longitudinal beam of adjacent sections being fixedly connected by flanges and bolts.

[0008] Furthermore, multiple reinforcing strips are fixedly connected at intervals between the aforementioned inclined beam and the top longitudinal beam.

[0009] The beneficial effects of this utility model are as follows: Compared with the prior art, the effects of this utility model are as follows:

[0010] (1) The special lifting tool uses multiple sets of chains and chain locks to evenly suspend the steel bars on the top plate of the T-beam steel cage. Combined with the truss of the strip frame structure, the lifting is stable and reliable, and the force is even, avoiding damage to the T-beam steel cage. It can ensure that the T-beam steel cage (T-beam steel skeleton) is lifted smoothly and without deformation. Sufficient rigidity and durability are considered when making the lifting tool, and the large lifting weight of the steel skeleton is also taken into account. The complete steel cage is welded outside the mold, which has a large space and is more conducive to welding and manufacturing.

[0011] (2) The truss structure of the bottom strip frame and the top longitudinal beam is fixedly connected to the bottom strip frame and the top longitudinal beam through multiple sets of figure-eight diagonal braces. It has high rigidity and strength, and is stable for hoisting. Multiple horizontal beams are used, and chains are arranged on the horizontal beams to facilitate the arrangement and installation of the hanging points.

[0012] (3) A fixed seat is set up to connect the hook of the gantry crane. The hooking is convenient. Specifically, the inclined beam is used to connect the connecting seat. The unloading plays a role in improving the rigidity of the truss. The connecting seat is convenient for hooking. Compared with the conventional hook, the two steel wire ropes are connected to the truss near the two ends, and the hooking is more stable and reliable. The multi-section docking structure makes it convenient to lengthen or shorten according to the length of the T-beam steel cage. Attached Figure Description

[0016] The utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Lifting equipment 3 is a crane-type lifting device installed between the rebar cage binding jig and the T-beam production mold. The lifting equipment's traveling track is installed between the rebar cage binding jig and the T-beam production mold, and is used to lift the T-beam rebar cages that have been bound on the rebar cage binding jig into the T-beam production mold. The lifting equipment directly transports the bound rebar cages into the T-beam production mold, and connects the concrete placing equipment installed above the T-beam production mold with the concrete mixing equipment through the concrete conveying equipment, realizing the rapid transfer of materials (rebar cages and concrete) between processes, greatly improving production efficiency and reducing scheduling difficulty.

[0018] The hoisting equipment 3 is a gantry crane. The hook of the gantry crane is a lifting device used for T-beam steel cages to hang the T-beam steel cages. During the suspension process, manual assistance is required to control the orientation of the T-beam steel cages to avoid impact.

[0019] Example 1, as Figure 1-3 As shown, a lifting device for a T-beam reinforcement cage includes a truss 3201, a chain 3202, and a chain lock 3203. The chain lock 3203 is a ring structure with a long nut locking the open end. Before use, the long nut is rotated to one end to expose the opening. The reinforcement to be hung is then inserted into the opening, and the long nut is connected to the two free ends of the lock to close the lock. A fixing seat 3204 is symmetrically fixedly connected to the top side of the truss 3201. A center of the top side of the fixing seat 3204 is provided with... The hook holes 32049 are used for attaching crane hooks. Each chain 3202 has two chain buckles 3203 at both ends. Multiple sets of chains 3202 are evenly arranged along the length of the truss 3201. Each set of chains 3202 consists of four chains. The middle of each chain 3202 is fixedly connected to the truss 3201. Each chain buckle 3203 is hooked onto the reinforcing bars of the T-beam reinforcement cage. Specialized hoisting equipment and special lifting tools are used to hoist the T-beam reinforcement cage. The special lifting tools use multiple... The chain and chain locks evenly suspend the reinforcing bars on the top plate of the T-beam reinforcement cage. Combined with the truss of the strip frame structure, the hoisting is stable and reliable, with even stress distribution, preventing damage to the T-beam reinforcement cage. Specifically, the truss 3201 includes a bottom strip frame 32011 and a top longitudinal beam 32012. The top longitudinal beam 32011 is parallel to the length of the bottom strip frame 32012. The top longitudinal beam 32011 and the bottom strip frame 32012 are secured to each other by multiple sets of symmetrically arranged V-shaped diagonal braces 32013. The bottom strip frame 32012 is fixedly connected to multiple crossbeams 32014 at even intervals in the middle. The lower ends of two adjacent sets of V-shaped diagonal braces 32013 are fixedly connected to both sides of a crossbeam 32014. The truss structure of the bottom strip frame 32012 and the top longitudinal beam 32011 is fixedly connected to the bottom strip frame and the top longitudinal beam through multiple sets of V-shaped diagonal braces. It has high rigidity and strength, and is stable for hoisting. Multiple crossbeams are used, and chains are arranged on the crossbeams to facilitate the arrangement and installation of hanging points.

[0020] Specifically, the fixing seat 3204 includes two inclined beams 32041 and a connecting seat 32042. One end of the two inclined beams 32041 is symmetrically fixedly connected to both sides of the connecting seat 32042, and the other end of the two inclined beams 32041 is fixedly connected to two support seats 32043. The support seats 32043 are fixedly connected to the top longitudinal beam 32011. The connecting seat 32042 includes a T-shaped square tube seat 32044, a base plate 32045, and a side plate 3204. 6. A hanging lug plate 32047 is provided with a hanging hole 32049. The lower end of the T-shaped square tube base 32044 is fixedly connected to the base plate 32045. Two side plates 32046 are used, which are respectively fixedly connected to both sides of the vertical beam of the T-shaped square tube base 32044 and fixedly connected to the horizontal beam of the T-shaped square tube base 32044 and the base plate 32045. The hanging lug plate 32047 is fixedly connected to the top of the horizontal beam of the T-shaped square tube base 32044. Furthermore, maintaining the same length direction, multiple pairs of reinforcing ribs 32048 are provided on both sides of the lifting lug plate 32047 and fixedly connected to the top of the horizontal beam. The lifting lug plate is provided with hook holes for attaching hooks, and a fixed seat is provided for connecting the hooks of the gantry crane, which is convenient for attachment. Specifically, a diagonal beam is used to connect the connecting seat, which improves the rigidity of the truss during unloading. The connecting seat facilitates the attachment of hooks, which is more stable and reliable than the conventional hooks that attach two steel wire ropes to the truss near the two ends. The truss is composed of multiple sections joined together. The bottom strip frame and the top longitudinal beam of adjacent sections are fixedly connected by flanges and bolts. The multi-section joint structure makes it easy to lengthen or shorten according to the required length of the T-beam reinforcement cage. In order to increase the connection reliability of the fixed seat 3204, multiple reinforcing strips 32050 are fixedly connected at intervals between the diagonal beam 32041 and the top longitudinal beam 32012. The reinforcing strips further improve the connection reliability and safety of the fixed seat.

[0021] Because the T-beam steel reinforcement cage has a large area and heavy weight, in order to ensure that the steel reinforcement cage is lifted smoothly and without deformation, a special lifting tool is used for lifting. Sufficient rigidity and durability are considered when making the lifting tool, while also taking into account the large lifting weight of the steel reinforcement cage.

[0022] By using hoisting equipment equipped with the aforementioned specialized lifting tools, the tied steel cages can be directly transported into the T-beam production mold. Additionally, the concrete conveying equipment connects the placing equipment installed above the T-beam production mold with the concrete mixing equipment, enabling rapid material transfer (steel cages and concrete) between processes. This significantly improves production efficiency and reduces scheduling difficulties.

[0023] In the steel bar production workshop, according to the design drawings of the T-beam steel bar cage, the steel bar production workshop uses various steel bar cutting equipment, steel bar bending equipment, steel bar welding equipment, etc. to cut the steel bars to a set length, bend them to a set bending pattern, and weld small steel bars (such as steel bar frames) on the steel bar cage.

[0024] The steel reinforcement cage binding jig is used to transport the processed steel bars from the steel production workshop to the jig using forklifts, mobile trolleys, or hoisting equipment. The steel bars are then placed onto the jig manually or using hoisting equipment (for long steel bars) for T-beam reinforcement cage binding. The processed steel bars of various types are bound into T-beam reinforcement cages on the jig according to the design drawings. After the T-beam reinforcement cage is bound, corrugated metal pipes (used for prefabricated duct forming) are inserted to form the T-beam reinforcement cage. The final T-beam reinforcement cage is then hooked together using chain locks on the hoisting device, ensuring balanced and stable stress distribution.
