Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a steel bar hoisting device for vertical concrete structures. Background Technique

[0002] With the increasing design spans of bridges such as cable-stayed bridges and suspension bridges, the tower column heights are also different. With the structural changes, the steel bars will increase the steel bar diameter, increase the number of steel bars, reduce the steel bar spacing, and improve the positioning accuracy in the design, thus facing the above steel bar installation requirements in high-altitude operations. The speed of steel bar hoisting operations is the key to affecting subsequent construction.

[0003] Traditional operation methods: For high-altitude hoisting operations of large-diameter and dense steel bars, either hoist them in units of single bars. This method has many round-trip hoisting times, long mechanical occupancy time and low efficiency. Or hoist them in units of bundles. Due to the limited high-altitude operation platform, this method cannot stack a large amount and causes secondary handling, increasing the operation process. Both are not conducive to construction progress control and cost control.

[0004] The publication number CN212174220U discloses a steel bar hoisting device and a steel bar hoisting support assembly on December 18, 2020, which relates to the technical field of hoisting tools. The steel bar hoisting device includes a first positioning plate, a second positioning plate and a third positioning plate. The first positioning plate and the second positioning plate are installed at intervals on the third positioning plate, and the first positioning plate, the second positioning plate and the third positioning plate enclose a receiving groove for placing steel bars. The first positioning plate and the second positioning plate can move relative to the third positioning plate. When the above-disclosed steel bar hoisting device moves, the steel bars are prone to shaking, and the steel bars cannot be hoisted and moved smoothly, and the practicability is poor. Content of the Utility Model

[0005] The purpose of the utility model is to provide a steel bar hoisting device for vertical concrete structures that is convenient for stably moving steel bars. The utility model places the steel bars on the hoisting frame through the hoisting assembly, and prevents the steel bars from shaking during the movement through the clamping assembly, realizing the stable movement of the steel bars.

[0006] To achieve the above purpose, the technical solution adopted by the utility model to solve its technical problems is: a steel bar hoisting device for vertical concrete structures, including a hoisting frame, a hoisting assembly for hoisting steel bars is arranged on the hoisting frame, a clamping assembly for clamping steel bars is arranged on the hoisting frame, the hoisting frame includes an upper cross beam, an intermediate rod and a lower cross beam, one end of the intermediate rod is connected to the upper cross beam, the other end of the intermediate rod is connected to the lower cross beam, the hoisting assembly is connected to the upper cross beam, the clamping assembly is connected to the lower cross beam, the hoisting assembly includes a hook and a sling, the hook is connected to the upper cross beam, the sling is connected to the hook, a screw rod is arranged on the hook, the screw rod is connected to the upper cross beam, and a fixing nut is arranged on the screw rod.

[0007] A gasket is provided between the fixed nut and the upper crossbeam.

[0008] As a further solution of the present utility model, the clamping assembly includes a spring and a contact block. A through groove is provided on the lower crossbeam. The spring is connected to the groove wall of the through groove, and the spring is connected to the contact block.

Moreover, the entire device can lift multiple steel bars at one time and complete precise positioning and installation in one lifting, optimizing the working time of high-altitude steel bar operations.

[0013] The convenient connection of the steel bars on the lifting frame is realized through the hook and the sling on the upper crossbeam, while the steel bars are conveniently clamped through the spring and the contact block in the through hole of the lower crossbeam to prevent the steel bars from shaking in the through groove. The hook is connected to the upper crossbeam through a screw rod, and a fixed nut is provided on the screw rod, thereby preventing the hook from falling off during movement and further ensuring the safe movement of the steel bars.

[0021] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0022] As Figure 1 shown, a vertical concrete structure steel bar hoisting device includes a hoisting frame 1. A hoisting assembly for hoisting steel bars is provided on the hoisting frame 1, and a clamping assembly for clamping steel bars is provided on the hoisting frame 1. Specifically, the hoisting device and the clamping device respectively perform hoisting and clamping operations on both ends of the steel bar.

[0023] During use, one end of the steel bar is connected to the hoisting assembly of the hoisting frame 1, and the other end of the steel bar is clamped by the clamping assembly. Then, the hoisting frame 1 is moved, so that the steel bar on the hoisting frame 1 moves. Furthermore, under the working action of the hoisting assembly and the clamping assembly, the steel bar is not likely to shake during the movement, thereby ensuring the stable hoisting and movement of the steel bar, and having higher practicability.

[0024] Referring to Figure 1-5 , the hoisting frame 1 includes an upper crossbeam 101, an intermediate rod 102 and a lower crossbeam 103.

[0025] The hoisting assembly includes a hook 3 and a sling 4. The hook 3 is connected to the upper crossbeam 101, and the sling 4 is connected to the hook 3. One end of the sling 4 is connected to the hook 3, and the other end of the sling 4 is wound around the steel bar, thereby ensuring the convenient disassembly and assembly of the steel bar.

[0026] Referring to Figure 2, a screw rod 5 is provided on the hook 3, and the screw rod 5 is connected to the upper cross beam 101. The convenient disassembly and assembly of the hook 3 on the upper cross beam 101 are realized through the screw rod 5.

[0027] A gasket 7 is provided between the fixing nut 6 and the upper cross beam 101. The upper cross beam 101 is protected through the gasket 7 to prevent the fixing nut 6 from rotating and squeezing the upper cross beam 101, and to prevent the surface of the upper cross beam 101 from being damaged.

[0028] The clamping assembly includes a spring 8 and a contact block 9. A through groove 10 is provided on the lower cross beam 103. The spring 8 is connected to the groove wall of the through groove 10, and the spring 8 is connected to the contact block 9. One end of the steel bar passes through the through groove 10. Then, the contact block 9 in the through groove 10 clamps the steel bar under the action of the spring 8, thereby preventing the steel bar from shaking during the movement. In this embodiment, sixteen through grooves 10 are provided, and two springs 8 are symmetrically provided in each through groove 10. Thus, the contact blocks 9 on the two springs 8 stably clamp the end of the steel bar.

[0029] Specifically, the upper cross beam 101 is an I-beam, and the middle rod 102 and the lower cross beam 103 are channel steels.

[0030] Lifting rings 2 are provided on the lifting frame 1. The entire lifting frame 1 and the steel bars are conveniently moved through the lifting rings 2. In this embodiment, two lifting rings 2 are provided, and the two lifting rings 2 are welded to the upper cross beam 101.
