Description

Bored concrete pile steel reinforcement cage fisher

Technical Field

The utility model relates to the technical field of construction tool devices, in particular to a fisher for a cast-in-place pile reinforcement cage.

Background

The urban rail transit engineering is a sign for urban development, and the climax of subway construction is raised in the whole country in recent years, so that the investment is huge, and dozens of new lines are opened every year. Subway construction is mostly in city economic circle, and usable soil is less, mostly is underground station, relates to deep basal pit, and the bored concrete pile is foundation pit retaining structure construction indispensable content, and steel reinforcement cage hoist and mount drops and fall into occasionally to take place under the condition in stake hole, if the steel reinforcement cage does not salvage, firstly handles the difficulty, secondly handles not good must influence pile foundation construction quality, thirdly causes economic loss.

At present, the self-made metal hook is adopted for fishing the steel reinforcement cage, the weight of the metal hook is light, the depth of a pile hole can reach tens of meters, the specific gravity of slurry in the hole is large, the distance between stirrups of the steel reinforcement cage is small, the metal hook is difficult to hang the steel reinforcement cage, and the efficiency and the success rate of fishing the steel reinforcement cage are low.

Disclosure of Invention

The utility model aims to solve the defects of the prior art and provides a cast-in-place pile reinforcement cage fisher.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a bored pile reinforcement cage fisher, comprising:

the hollow bracket is of a frame structure, and the lower part of the hollow bracket is wide at the top and narrow at the bottom;

the hooks are arranged along the circumferential direction of the lower part of the hollow support, and the outer ends of the hooks extend out of the outer side of the hollow support.

Furthermore, the lower part of the hollow support is in an inverted triangular pyramid shape.

Furthermore, the number of the hooks is three and the hooks are respectively positioned on three edges of the triangular pyramid.

Furthermore, the hook is connected with the hollow bracket in a welding mode.

Furthermore, the top of the hook is hinged with the hollow bracket.

Furthermore, an inclined plate is fixedly arranged on the side part of the hook.

Furthermore, the outer end of the hook is provided with a balancing weight, and the middle part of the hook is connected with a sling which is convenient to pull the hook.

The utility model has the beneficial effects that: the utility model has simple structure, can be manufactured by processing and welding waste steel bars, has low cost, simple operation, convenient use and strong generalization; the hollow support adopts a frame structure, reduces the resistance of lowering and lifting, has certain scalability, and has stronger stability in the salvaging and lifting process.

the following detailed description will be made in conjunction with embodiments of the present invention with reference to the accompanying drawings.

Detailed Description

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

as shown, the present embodiment includes:

the support comprises a hollow support 1, wherein the hollow support 1 is of a frame structure, the lower part of the hollow support 1 is in an inverted triangular pyramid shape with a wide upper part and a narrow lower part, the whole hollow support 1 is in a shuttle shape, and the hollow support 1 is formed by welding round steel with the diameter of 25mm or 22 mm;

three couple 2, three couple 2 sets up and is located three arriss of triangular pyramid respectively along the circumference of fretwork support 1 lower part, and couple 2 adopts diameter 25mm or 22 mm's round steel bending to form and with fretwork support 1 welded connection equally, and the fretwork support 1 outside is stretched out to the outer end of couple 2.

During the use, the diameter of on-spot drilling bored concrete pile is 1200mm, steel reinforcement cage diameter is 1060mm, spindle-shaped's hollow out support 1 widest part is outer along place circumference diameter for 1000mm, long 4500mm, three couple 2 is outer along place circumference diameter for 1116mm, the hook length 549mm, couple 2 that the round steel was made can take place elastic deformation, can open certain angle after hooking the stirrup, make the combination between them more firm, can inwards draw in under the effect of external force during the unhook, the convenient unhook. Firstly, the utility model is adjusted above a pile hole by using a crawler crane, the utility model is put to the depth of a reinforcement cage, the crawler crane is lifted, and the hook 2 is hooked on a stirrup of the reinforcement cage in the lifting process, so that the reinforcement cage is lifted along with the utility model until the reinforcement cage is lifted to an orifice.

In addition, couple 2 still can adopt top and the articulated structure of

fretwork support

1, 2 lateral parts of couple have set firmly hang plate 3 under this structure, and the outside of hang plate 3 is higher than inboard to the messenger transfers in-process mesopore mud to make couple 2 pack up to the effort that hang plate 3 was applyed, lift the downthehole mud of in-process and apply the counter force to hang plate 3 and make couple 2 open, and then hook the stirrup of steel reinforcement cage more easily, can further increase the success rate of salvaging like this.

In addition, on the basis of the hinge structure of the hook 2, the outer end of the hook 2 can be provided with a balancing weight 4, so that the gravity center of the hook 2 is positioned at the outer side of the hinge point, and the hook can be retracted inwards under the action of the self weight of the hook 2; even there is the hoist cable 5 of being convenient for to pull up it in the middle part of couple 2, is equipped with a plurality of guide rings that are used for leading hoist cable 5 on the fretwork support 1, transfers the accessible after targetting in place and carries and carry hoist cable 5 and realize opening of couple 2 to hook the stirrup of steel reinforcement cage more easily, can further increase the success rate of salvaging like this.

The utility model has been described in connection with the accompanying drawings, it is to be understood that the utility model is not limited to the specific embodiments disclosed, but is intended to cover various modifications, adaptations or uses of the utility model, and all such modifications and variations are within the scope of the utility model.
