Abstract
The invention discloses a hoop type clamping device comprising hoops and a tightening bolt for connecting the hoops together. Each hoop is formed by pivoting of a plurality of arc-shaped hoop pieces which are in up-down symmetry and are hinged through a plurality of hinge connecting pins. The arc-shaped hoop pieces encircle a hoop claw to form a circular-ring-shaped hinge. A threaded hole is formed in a trunnion of the hinge connecting pin at one end of each hoop, and the tightening bolt is connected into the threaded holes in a threaded manner. The hoop claw is provided with a plurality of arc-shaped jaws which are connected with the inner walls of the hoop pieces to form a circular tube structure capable of being matched with a pipeline. The hoop type clamping device has the advantages that structure is simple, uniform pressure distribution of the to-be-connected pipeline can be achieved, stress is reasonable and the problem of deformation of a pipeline joint due to ultrahigh intensity of pressure is solved; the pipeline can be clamped through connection via the tightening bolt, so that mounting workload and mounting cost are greatly lowered.

Background technique
At present, submarine pipeline connector is mainly used in the connection between underwater production facility pipeline, as: subsea production tree and subsea manifold, underwater line and subsea production tree, duct end (PLET) and duct end manifold (PLEM) etc. are the important guarantees of deep water hydrocarbon Safety Examination.The submarine pipeline connector of complete set mainly by being connected to the adapter connector end of cross-over connection pipe end under water, the lower flange end be arranged on underwater production facility forms.Underwater connector lower flange end is installed to seabed together in advance along with underwater installation, and adapter connector end is transferred to seabed together along with jumper pipe, and then, abutting joint is carried out under water in two ends.
Existing submarine pipeline connector is roughly divided into three kinds: jack catchs type connects, fixture type connects and is connected with flange-type.Wherein, jack catchs type connects for conventional submarine pipeline connector, is connected and composed by an individual layer clip sheet and multiple pawl.During use, it easily makes the pipeline be connected be stressed skewness, and excessive to pipeline pressure due to it, the distortion of the pipe coupling caused.
Summary of the invention
Main purpose of the present invention is the above-mentioned shortcoming overcoming prior art existence, and a kind of clamp band type clamp device is provided, its structure is simple, and the pipeline pressurized be connected can not only be made to be evenly distributed, stressed more reasonable, solve the problem on deformation due to excessive the caused pipe coupling of pressure; And, connected by a turnbuckle, just can realize the clamping to pipeline; Greatly reduce installation workload and installation cost is installed.
The object of the invention is to be realized by following technological scheme:
A kind of clamp band type clamp device, it is characterized in that: comprising: clip, by clip connected turnbuckle together, wherein, clip is by several upper and lower symmetry and consists of several arc-shaped clamp sheet pivot joint that several chain connection pin is hinged, and a clip pawl is trapped among a middle part formation ring hinge by several arc-shaped clamp sheet; Wherein the gudgeon of the chain connection pin of one end is provided with tapped hole, and turnbuckle is screwed onto in tapped hole; This clip pawl be provided with several arc-shaped claws, several arc-shaped claws and clip sheet inwall connect and compose one can with the circular tube structure of tube fit.
Described arc-shaped clamp sheet comprises: the right clip sheet that the middle clip sheet that a left clip sheet, the pin that is connected through the hinge are connected with left clip sheet, the pin that is connected through the hinge are connected with middle clip sheet, by the turnbuckle that right clip sheet and left clip sheet are screwed together; The parcel angle of this arc-shaped clamp sheet is 120 °.
Adopt drive fit mode that several connecting struts is installed between described several arc-shaped clamp sheet.
The cross section of described arc-shaped claws is: [shape structure.
Beneficial effect of the present invention: the present invention is owing to adopting technique scheme, and its structure is simple, and the pipeline pressurized be connected can not only be made to be evenly distributed, stressed more reasonable, solve the problem on deformation due to excessive the caused pipe coupling of pressure; And, connected by a turnbuckle, just can realize the clamping to pipeline; Greatly reduce installation workload and installation cost is installed.
