Abstract
The utility model relates to a kind of steel pile casting accurate positioning device, belongs to engineering construction equipment technical field.This device comprises: shaped steel frame and level are located at the multiple jack on described shaped steel frame; Have the space of up/down perforation to hold steel pile casting in the middle of described shaped steel frame, described jack is uniform in the surrounding of described steel pile casting, and its one end is fixed, and the other end is towards described steel pile casting; When described jack extends, clamp described steel pile casting.Steel pile casting accurate positioning device of the present utility model, structure is simple, and utilization is positioned at top and surrounding each 4 jack in bottom realize the adjustment of steel pile casting position, reaches pinpoint object.Jack end arranges roller bearing, in the process of follow-up sinking steel pile casting, sliding friction is become rolling friction like this, does not affect sinking watching.
Description
Technical field
The utility model relates to a kind of steel pile casting positioner, belongs to engineering construction equipment technical field.
Background technology
When ground is unstable in bridge construction, need to sink to steel pile casting in advance, then carry out drilled pile in steel pile casting again.The effects such as steel pile casting can stablize hole wall in advance, prevents the hole that collapses, and can also isolate surface water, starter, spud pile position, protection operation original ground.When profundal zone operation at sea, steel pile casting length is large compared with long, structure, from great, positioning accuracy request is higher.
At present, the leading truck of domestic routine is generally steel truss structure, carries out leading truck location by the axis of steel pile casting.The method positioning precision is not high, and efficiency of construction is lower, and may occur the problems such as leading truck moves in heavy process under vibration.Therefore, appropriate design steel pile casting locating guide device, can ensure precision, improves workmanship, reduces the working time, the advantage such as to increase work efficiency.
How to ensure the accuracy of sinking steel protecting canister process median-plane location, and verticality when how to ensure sinking steel protecting canister, be the important ring ensureing workmanship.In addition, under the prerequisite ensureing workmanship, improving casing sinking efficiency, is also save the very important part of engineering cost.
Summary of the invention
The technical problems to be solved in the utility model is: the above-mentioned defect overcoming prior art, provides a kind of structure simple, easy to adjust and can pinpoint steel pile casting.
The utility model is the technical scheme solving the problems of the technologies described above proposition: a kind of steel pile casting accurate positioning device, comprising: shaped steel frame and at least four jack be fixed on described shaped steel frame; Be formed in the middle of described shaped steel frame and can allow the space of described steel pile casting break-through from top to bottom, described jack the top of described shaped steel frame and bottom surrounding horizontal symmetrical uniform, when described jack extends on the described steel pile casting of its top clamping.
Such scheme further improves and is: described jack is eight, and 90 degree, interval is arranged on top and the bottom surrounding of described shaped steel frame respectively.
Such scheme further improves and is: the top of described jack is hinged with roller bearing.
Steel pile casting accurate positioning device of the present utility model, structure is simple, and utilization is positioned at shaped steel frame top and surrounding each 4 jack in bottom realize the adjustment of steel pile casting position, reaches pinpoint object.The hinged roller bearing of jacking header, becomes rolling friction by sliding friction like this, does not affect sinking watching in the process of follow-up sinking steel pile casting.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model preferred embodiment.
Number in the figure is schematically as follows: 1-shaped steel frame, 2-jack, 3-roller bearing.
Detailed description of the invention
embodiment one
The steel pile casting accurate positioning device of the present embodiment as shown in Figure 1, comprising: shaped steel frame 1 and eight jack 2 be fixedly mounted on shaped steel frame 1; Space in the middle of shaped steel frame 1 can hold steel pile casting and pass through from top to bottom.Jack 2 respectively 90 degree, interval is arranged on bottom surrounding and the top surrounding of shaped steel frame 1, relative shaped steel frame 1 Central Symmetry.
The top of jack 2, towards shaped steel frame 1 center, it is hinged with roller bearing 3.
During construction, according to the size of steel pile casting, jack 2 is installed with the device of angle steel welding production the present embodiment.After completing, this device is lifted into the position needing sinking steel pile casting.And then lift steel pile casting and enter in the space of the center of this device, after guaranteeing contact riverbed at the bottom of steel pile casting, go out to regulate the stroke of the bottom jack of steel pile casting according to the diameter of steel pile casting and the Size calculation of this device, start bottom jack and steel pile casting is clamped.Now, precalculated position on earth bottom steel pile casting.
Due to the inevitable out-of-flatness in riverbed, steel pile casting also has the problem of verticality, therefore also needs two transits to observe the verticality of steel pile casting, if discovery out of plumb, then regulate, after verticality furnishing completes with top jack, and after being clamped by steel pile casting, can the steel pile casting that sinks be started.Because jack 2 top is provided with roller bearing 3, jack 2 and steel pile casting are rolling friction, and frictional force is very little, on sinking watching without any impact.So can realize accurate location and the guiding of sinking steel protecting canister process.
The utility model is not limited to above-described embodiment.All employings are equal to the technical scheme of replacing and being formed, and all drop on the protection domain of the utility model requirement.
