Description
Technical field
The utility model relates to a kind of device adjusting annular groove misalignment, particularly relates to swollen device in a kind of steel pipe.
Background technology
In the process of daily highway or bridge construction, need in the light of actual conditions to come to weld steel pipe, reach construction requirement to make it.In the various welding manner such as docking, hoop welding of steel pipe, all require that the interface surface of two steel pipes to be welded is concordant, the annular groove staggered edge free of steel pipe, but owing to being subject to the restriction of construction site condition or the differentia influence of steel pipe processing conditions, cause uneven, the annular groove staggered edge free of the counterpart of two steel pipes to be welded, cannot two ensure the quality of steel-pipe weldings, also have impact on the progress of construction.Usually adpting flange or clip lap welding are connected on the interface of two steel pipes in prior art, thus the impact that artificial elimination counterpart is uneven, but increase inventory charge like this, increase human cost simultaneously.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of effective adjustment misalignment size, improves swollen device in the steel pipe of the efficiency of butt welding and saving material.
The technical scheme that the utility model adopts is: the utility model comprises the expanding tense machine being arranged on steel duct, the hydraulic power unit be connected with described expanding tense machine, described expanding tense machine is provided with some hydraulic cylinders, some described hydraulic cylinders are connected with described hydraulic power unit, and the piston outer end of some described hydraulic cylinders is provided with rubber contact.
Described expanding tense machine is cross-shaped configuration, and is divided into two-layer, and every layer arranges four described hydraulic cylinders, and leaves through hole in centre, described hydraulic power unit is provided with carrier pipe, and described carrier pipe, through described through hole, is connected with the input port of described hydraulic cylinder.
Described carrier pipe and described hydraulic power unit are all fixedly installed travelling car, and the described travelling car be arranged on described carrier pipe should ensure that described carrier pipe can pass described expanding tense machine.
In described steel pipe, swollen device also comprises base, and when needing to use, described base is fixedly installed between described expanding tense machine and steel pipe inner wall.
The beneficial effects of the utility model are: because the utility model comprises the expanding tense machine being arranged on steel duct, the hydraulic power unit be connected with described expanding tense machine, described expanding tense machine is provided with some hydraulic cylinders, some described hydraulic cylinders are connected with described hydraulic power unit, and the piston outer end of some described hydraulic cylinders is provided with rubber contact.Described expanding tense machine is placed in the docking port of two steel pipes, counterpart is closed, observes position that is uneven or misalignment, more described hydraulic power unit is communicated with described expanding tense machine, according to actual conditions to described hydraulic cylinder voltage supply, make its counterpart concordant from inner jack-up steel pipe.So the utility model effectively regulates misalignment size, improve the efficiency of butt welding.
Because described expanding tense machine is cross-shaped configuration, and be divided into two-layer, every layer arranges four described hydraulic cylinders, and leaves through hole in centre, described hydraulic power unit is provided with carrier pipe, and described carrier pipe, through described through hole, is connected with the input port of described hydraulic cylinder.Be that different described hydraulic cylinder carries out voltage supply by described carrier pipe, make described expanding tense machine realize the multiple adjustment modes such as single action, diagonal linkage, one-sided four cylinder interlocks.
Due to described carrier pipe and described hydraulic power unit being all fixedly installed travelling car, the described travelling car be arranged on described carrier pipe should ensure that described carrier pipe can pass described expanding tense machine.Be positioned at described travelling car on described carrier pipe and described hydraulic cylinder all with steel pipe inner wall joint, so described carrier pipe can insert in described expanding tense machine by the utility model exactly, provide efficiency.
Because device swollen in described steel pipe also comprises base, when needing to use, described base is fixedly installed between described expanding tense machine and steel pipe inner wall.When the steel pipe regulating external diameter larger, described base is arranged between described expanding tense machine and steel pipe inner wall, plays padded effect.So the misalignment that the utility model can be applicable to large external diameter steel pipe regulates.

Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, the hydraulic power unit 2 that the utility model comprises expanding tense machine 1 and is connected with described expanding tense machine 1, described expanding tense machine 1 is divided into two-layer, the cross-shaped configuration combined by four hydraulic cylinders 3 is equipped with in every layer, and a through hole 5 is left on the position, middle of described cross-shaped configuration, the least significant end of described hydraulic cylinder 3 output is provided with rubber contact 4; Described hydraulic power unit 2 is provided with carrier pipe 6, and described carrier pipe 6 through described through hole 5, and is connected with the input port of hydraulic cylinder described in each 3.First described expanding tense machine 1 is placed on steel duct docking port place during use, then push-tight two steel pipes make its docking port be close together, and observe the alignment condition at docking port place and record.Described carrier pipe 6 is goed deep in steel pipe, inserts described through hole 5 and make it be connected with hydraulic cylinder described in each 3.Start described hydraulic power unit 2, and according to record case to the voltage supply of described hydraulic cylinder 3, thus at inner jack-up steel pipe, its docking port is alignd as far as possible smooth.The output of hydraulic cylinder 3 described in described rubber contact 4 energy available protecting.
Described carrier pipe 6 and described hydraulic power unit 2 are all fixedly installed travelling car 7, facilitate described carrier pipe 6 and described hydraulic power unit 2 movement in use.The position set by described travelling car 7 be simultaneously positioned on described carrier pipe 6 should ensure that described carrier pipe 6 can pass described expanding tense machine 1.Further, the described travelling car 7 be arranged on described carrier pipe 6 all acts in steel pipe inner wall with described expanding tense machine 1, to ensure that described carrier pipe 6 aligns with described through hole 5.
Because the utility model is only applicable to external diameter at 2000mm-2250mm, pipe range at the steel pipe of about 3000mm, as the steel pipe of larger diameter need be docked, the base 8 of corresponding height only need be increased between described expanding tense machine 1 and steel pipe inner wall.Different according to actual conditions, the working methods such as the utility model can be linked between two by the single action of described hydraulic cylinder 3, diagonal angle, one-sided four cylinder interlocks adjust steel pipe.
The utility model is applicable to steel-pipe welding field.
