More preferably, each claw 143 of two groups of centering assemblies 14 circumferentially interlaced arrangement on housing 13, the interference of actuated piece 141 can be avoided, also allow for the abutment joint 4 of two pipelines is carried out follow-up welding operation.
It should be noted that according to described previously, pipeline of the present utility model assembling centralising device 1 can be separated into stream oriented device parts.It practice, the driving member 142 of foregoing housing 13 and centering assembly 14 all can be separated into two parts, respectively constitute a part for stream oriented device parts.When stream oriented device parts are stitched together, housing 13 and driving member 142 can form overall structure in the form of a ring.Actuated piece 141 and claw 143 can be distributed on two parts of housing 13 according to actual needs, as one group of centering assembly 14 in the present embodiment has three claws 143, then can one of them be arranged in a device feature, another two can be arranged in another device feature.Centralising device 1 is removable is divided into two parts in pipeline of the present utility model assembling, it is simple to pipeline has welded taking off of rear device, will not be limited by length of pipe.
Refering to Fig. 3 and Fig. 4, the housing 13 in the present embodiment includes the outside plate 131 of cylindrical shape, is respectively in the two end plates 132 at outside plate 131 two ends, and the dividing plate 133 being arranged between two end plates 132.
Outside plate 131 and end plate 132 form an entirety, the remaining part of device can be played basic supporting role.
End plate 132 is in step-like, the installation portion 136 installed for driving member 142 is formed between its step surface and outside plate 131, dividing plate 133, installation portion 136 matches with the contact surface of driving member 142, can be as the rotary shaft of driving member 142, motility during in order to ensure that device operates and accuracy, can be with this contact surface of grease lubrication.
Two groups of centering assemblies 14 are isolated by dividing plate 133, and meanwhile, dividing plate 133 also and forms the supporting part 137 of the inner end for supporting actuated piece 141 between end plate 132, outside plate 131 offers the installing hole 135 for supporting end, actuated piece 141 outer end.
Two end plates 132 is fixedly connected with dividing plate 133, outside plate 131.In the present embodiment, two end plates 132 is provided with bolt hole with the correspondence position of dividing plate 133, is connected by securing member 134 after fixing, can limit sliding axially of driving member 142;Securing member 134 can be made up of interior hexagonal or interior corner screw and pad, facilitates end plate 132 and the assembling of dividing plate 133 and the installation of miscellaneous part;Outside plate 131 is welded and fixed with end plate 132, makes device have more preferable bonding strength.
On outside plate 131 and end plate 132, correspondence offers the gathering sill for installing claw 143, it is ensured that each claw 143 does linear motion radially by fixed course.More preferably, the gathering sill on housing 13 is T-shaped, is adapted to the size that claw 143 is longer, and the cross section of each claw 143 is I-shaped, and matches with the T-shaped gathering sill on housing 13.
Claw 143 is overall L-shaped, and including elongated end and the bare terminal end 1432 being positioned at elongated end end, the cross section of claw 143 elongated end is I-shaped, and matches with the T-shaped gathering sill on housing 13;Bare terminal end 1432 extends along the central axis of housing 13 so that it is can have bigger contact area with pipeline when clamping pipeline, improve the clamping stability of device.
Above-mentioned pipeline of the present utility model assembling centralising device 1, more preferably, its material is aluminium alloy.Aluminium alloy can make device entirety reach smaller weight, and its intensity is suitable with steel, but weight only there are about the 1/3 of steel, it is simple to the transport of whole device is carried and operated with single.Set by this utility model pipeline assembling housing 13 internal diameter of centralising device 1 and each claw 143 are limited scope equidimension, can make device of the present utility model be applicable to more than 90% ocean engineering and shipbuilding the centering of pipeline.
Assembling centralising device 1 according to pipeline of the present utility model, this utility model also provides for a kind of pipeline joint assembly method.
Above-mentioned pipeline assembling centralising device 1 can be used to make two pipeline 2,3 centerings to be docked, then two pipelines 2,3 are implemented welding.
Specifically, substantially step is as follows:
S1, the first device parts 1a and the second device feature 1b that pipeline assembles centralising device 1 connect fixing, making each claw 143 limited range sectional area more than pipeline 2,3, the diameter of a circle that the bare terminal end 1432 of the most each claw 143 limits is greater than the external diameter of pipeline 2,3;
S2, the connection end of two pipelines to be docked is placed in claw 143 limited range, drives actuated piece 141 to make claw 143 move to the direction being perpendicular to pipeline axis to clamping pipeline;
S3, welding the abutment joint 4 of two pipelines, first device portion 1a and the second device section 1b that pipeline assembles centralising device 1 release and connect and take off from pipeline.
Wherein, with reference to Fig. 2, when pipeline assembling centralising device 1 has two groups of centering assemblies 14, in step s 2, specifically, pipeline is assembled the periphery that centralising device 1 is set in one end of pipeline 2, make the claw 143 about centre position at left side centering assembly 14, the end of pipeline 2, can conveniently weld;One of them actuated piece 141 during manually instrument drives left side centering assembly 14 rotates, and makes the pipeline 2 on the left of each claw 143 clamping in the first centering assembly 14a;Again pipeline 3 is placed in pipeline assembling centralising device 1 so that it is end leans against on the end face to be docked of pipeline 2;Manually on the right of instrument drive, one of them actuated piece 141 in centering assembly 14 rotates, and makes the pipeline 3 on the right side of each claw 143 clamping in the second centering assembly 14b, it is achieved the centering of pipeline 2,3.
It should be noted that the sequencing of pipeline 2 and 3 docking does not affect the use of this device, can the order of adjustment according to actual needs.Equally, pipeline 2 can be partial in the position of clamping, it is also possible to deflection pipeline 3, does not the most affect the using effect of this device.
Method of the present utility model, while ensureing pipeline joint precision, operates more quick, after two pipeline joints have assembled, can divide a device into two parts and take off from pipeline, will not be limited by length of pipe, save the working time.
