Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and more specifically, to a device for dismantling the bottom basket of an ultra-large hanging basket. Background Technology

[0002] In bridge engineering, the cantilever formwork method is a common approach for constructing cast-in-place continuous box girders. Typically, after the cantilever casting is completed, the formwork needs to be dismantled, a step often overlooked. Currently, during the dismantling of the bottom formwork, on-site construction equipment is rudimentary. Common auxiliary tools include wire ropes, precision-rolled threaded steel bars, and slings, which are barely sufficient for dismantling small formwork systems. When faced with large formwork systems (30t bottom formwork systems), they are completely inadequate in bearing the load, leading to problems such as easy breakage of auxiliary tools and asynchronous dismantling and lowering, posing potential safety hazards.

[0003] In view of the above, this application is hereby submitted. Utility Model Content

[0004] The technical problem this utility model aims to solve is that current tools such as wire ropes, precision-rolled threaded steel bars, and slings cannot meet the requirements for dismantling large hanging baskets. The purpose is to provide a dismantling device for the bottom basket of an ultra-large hanging basket. This device connects to the bottom basket system via suspended steel strands, with the ends of the steel strands connected to the already poured box girder. The bottom basket is then lowered using the telescopic movement of a lifting device, which increases the safety and synchronicity of the bottom basket dismantling. This device has a simple and reasonable structure, is easy to install, has a simple manufacturing process, is safe and reliable, and is economical. It can form a standardized process for construction auxiliary facilities.

[0005] This utility model is achieved through the following technical solution:

[0006] A bottom basket removal device for an ultra-large hanging basket includes a lifting device and a steel strand installed on a cast-in-place box girder. The lower end of the steel strand passes through the lifting device and the cast-in-place box girder in sequence and is connected to the bottom basket system. The upper end of the steel strand is wound around a steel strand storage winch.

[0007] The lifting device lowers the steel strands through telescopic movement to achieve the lowering operation of the basket system.

[0008] This utility model connects the suspended steel strand to the basket system and connects the end of the steel strand to the cast-in-place box girder. Then, the basket is lowered by the telescopic movement of the lifting equipment, which can increase the safety and synchronicity of basket removal. The device has a simple and reasonable structure, is easy to install, has a simple manufacturing process, is safe and reliable, and is economical. It can form a standardized process for construction auxiliary facilities.

[0009] In one specific embodiment, the bottom basket system consists of a rear lower crossbeam, a front lower crossbeam, longitudinal beams, and a bottom template.

[0010] In one specific embodiment, the lifting device adopts a through-hole hydraulic jack, and a telescopic cylinder is provided above the hydraulic jack. The lower end of the steel strand passes through the telescopic cylinder and the hydraulic jack in sequence, and the lowering of the steel strand is achieved by lifting and retracting the telescopic cylinder.

[0011] In one specific embodiment, a crossbeam is provided below the hydraulic jack, and pad beams are provided at both ends of the crossbeam, with the steel strand passing between the two pad beams.

[0012] In one specific embodiment, an upper anchor is provided above the telescopic cylinder and sleeved on the outside of the steel strand, and a lower anchor is provided at the point where the steel strand passes through the cast-in-place box girder and sleeved on the outside of the steel strand.

[0013] In one specific embodiment, an upper wedge block is detachably installed above the upper anchor, and a lower wedge block is detachably installed above the lower anchor.

[0014] In one specific embodiment, a hydraulic jack controller [S1] is also included, which is used to control the lifting and retraction of the telescopic cylinder.

[0015] In one specific embodiment, the pad beam, cross beam, and steel strand storage winch are all made of shaped steel.

[0016] In one specific implementation, a safety rope is also connected between the cast box girder and the basket system.

[0017] In one specific embodiment, the steel strand is connected to the basket system via anchors and wedges.

[0018] In one specific embodiment, the lifting device and the steel strand are provided in multiple sets.

[0019] In one specific embodiment, a barge is also included below the basket system for transporting the basket system to the shore after it is lowered.

[0020] The working principle of this utility model's basket removal device is as follows:

[0021] The first step is to lower the steel strands and pass them sequentially through the upper anchor, telescopic cylinder, hydraulic jack, lower anchor, and cast box girder, and then connect them to the bottom basket system.

[0022] The second step is to install pad beams and crossbeams between the lower end of the hydraulic jack and the cast box girder;

[0023] The third step is to lift the telescopic cylinder upwards and install a wedge block on the upper end of the telescopic cylinder for locking.

[0024] Fourth, retract the telescopic cylinder, lower the steel strand a certain distance, and the basket system will follow; after completion, install the lower wedge block on the lower anchor to lock it.
