Abstract
The utility model discloses an external pipe pusher, comprising a basic frame; the basic frame is provided with two vertical arms, the two vertical arms are respectively provided with an extension arm, each extension arm is provided with a hydraulic cylinder, and the outside of the push rod of each hydraulic cylinder is provided with calipers; The two extension arms are installed on the two vertical arms in the facing direction of the calipers, the lower end of the each vertical arm is provided with a rolling wheel, the basic frame is axially provided a slide way along a tube to be connected, the rolling wheel is installed in the slide way, the basic frame is axially provided with a hydraulic cylinder along the tube to be connected, and the push rod of each hydraulic cylinder is connected with the two vertical arms.In the utility model, outer pipes are clamped in horizontal direction by hydraulic control, and then the outer pipes are pushed to assemble in an axial direction.Compared with the original process adopting the leading chains or the winchs to assemble, the whole process of the assembly is shortened; the labor power is saved thereby.
Description
Technical field
The utility model relates to bobbin ejector, particularly relates to a kind of outer tube bobbin ejector when being applied to the welding of double-deck offshore oilfield pipeline.
Background technology
China's offshore oilfield pipeline much adopts the double-skin duct structure, and double-skin duct is meant tube-in-tube, promptly a tubule by big pipe box, the middle pipeline that separates with insulation material.And double-skin duct need be pushed to outer tube butt joint, welding outer tube again with after the interior pipe welding when laying.In the technology before this, outer tube butt joint is general to be adopted and leads chain and move two tubes to together means, and the shortcoming of this construction method is a length consuming time, and hand labour intensity is big, influences operation on the sea efficient.
The innovation and creation content
The purpose of this utility model provides a kind of simple, convenient and swift, time saving and energy saving outer tube bobbin ejector that uses.
For achieving the above object, the utility model is taked technical scheme: a kind of outer tube bobbin ejector includes a pedestal, described pedestal is provided with two upright arms, described upright arm top respectively is provided with an extending arm, is provided with hydraulic cylinder in the described extending arm, and the push rod outer setting of described hydraulic cylinder has clamp; Described two extending arms be installed in clamp on the upright arm of direction.
In practical operation, in order to make the intensity between the two upright arms better, so between described two upright arms, be provided with the reinforcement linking arm.And described two upright arm lower ends respectively are provided with roller, and to being provided with slideway, described roller is installed in the described slideway described pedestal along tubular axis to be connected, and to being provided with a hydraulic cylinder, the push rod of described hydraulic cylinder connects described two upright arms to described pedestal along tubular axis to be connected.
The utility model is owing to take above design, it has the following advantages: the utility model laterally blocked outer tube by hydraulic control before this, right in axial promotion outer tube group then, whole process leads chain with employing use in the past or the winch group is organized the right time to comparing to have shortened greatly, has saved manpower; In addition, the utility model solved the collar extension group to after, a difficult problem that is difficult to withdraw, therefore in practical operation, after treating that internal orifice has inspected, can begin to push away the step of outer tube immediately, not need to wait for assay, if the internal orifice disqualified upon inspection, the outer tube bobbin ejector can also withdraw outer tube very soon; Clamp of the present utility model can differently according to the size of outer tube arbitrarily be changed, and are very convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the left view of Fig. 1
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, a kind of outer tube bobbin ejector, include a pedestal 1, pedestal 1 is provided with two upright arms 2, in order to make the intensity between the two upright arms 2 better, be provided with between the two upright arms and strengthen linking arm 21, upright arm 2 tops respectively are provided with an extending arm 3, be provided with hydraulic cylinder 31 in the extending arm 3, push rod 32 outer setting of hydraulic cylinder 31 have clamp 33; Two extending arms 3 with clamp over against direction be installed on the upright arm 2, so when in use, only need promote clamp by hydraulic cylinder blocks pipeline to be connected, and, for the pipeline of different size, the clamp that only need to change different size just can be processed operation.
Two upright arm 2 lower ends respectively are provided with roller (figure does not show), pedestal 1 along tubular axis to be connected to being provided with slideway (figure do not show), and roller is installed in the slideway, to being provided with a hydraulic cylinder 4, the push rod of this hydraulic cylinder 4 connects two upright arms 2 to pedestal 1, like this along tubular axis to be connected, after clamp block pipeline to be connected, the upright arm 2 of primer fluid cylinder pressure 4 promotions, can make two outer tube groups right, and then weld to moving along tubular axis to be connected.
The utility model concrete operations when using are as follows:
At first, pipeline to be connected is passed between the two upright arms, when interior pipe welding finish and through check after no problem, start the hydraulic cylinder on the extending arm, make that the distance between two clamp shortens, thereby with the outer tube clamping of pipeline; After outer tube clamps, start the hydraulic cylinder on the pedestal, promote two upright arms, thus drive outer tube to another root pipeline move outer tube when two pipelines link together organize to after, weld other work that waits.
Claims (4)
