Embodiment Construction

[0027] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0028] like Figure 1 to Figure 2 As shown, the pipeline clamping tool according to the embodiment of the present invention includes: a base 1, a clamping part 3 for clamping a pipeline, a first hydraulic cylinder 31 for driving the clamping part to rotate, and locking the clamping part the locking part.

[0029] The clamping part 3 is hinged on the base 1 through the hinge shaft 33, and through its own rotation, clamps and releases the pipeline. The first hydraulic cylinder 31 is arranged on the base 1 and connected with the clamping part 3 , the first hydraulic cylinder 31 is connected with the clamping part 3 through a connecting shaft 39 so as to push the clamping part 3 around the hinge axis 33 Turn to complete gripping an...

Abstract

The invention provides a pipeline clamping tool and a pipeline lifting method. the pipeline clamping tool comprises a pedestal, a clamping part of the clamping pipeline which is hinged on the pedestal by a hinge shaft; a first hydraulic cylinder which drives the rotation of the clamping part and is arranged on the pedestal and is connected to the clamping part; and a locking part which is used for locking the clamping part and is arranged on the pedestal in a movable mode. The invention also provides a pipeline lifting method, the pipeline lifting method comprises the following steps: driving the rotation of the clamping part by the first hydraulic cylinder and clamping the pipeline, then driving the locking part, preventing the rotation of the clamping part, and then lifting the pipeline and stopping the oil supply on the first hydraulic cylinder during the lifting process.

Description

technical field [0001] The invention relates to a pipe clamping tool and a pipeline lifting method. The pipeline clamping tool and the pipeline lifting method are applied to the pipe lifting frame in the deep water pipeline emergency repair equipment, and its main function is to clamp the seabed pipeline to be repaired so as to lift the pipeline. Pipe racks lift pipes. Background technique [0002] Currently, deepwater oil development is in its infancy, and so is deepwater emergency maintenance. Deep water has a high-pressure and low-temperature environment. Considering the influence of factors such as water depth, pipeline size, pipeline pressure, and soil conditions, the performance requirements for these maintenance equipment will exceed the previous industry standards. These performance requirements include clamping devices for multiple pipe diameters, hydraulic seal joints\pipe retrieval tools (GSHC\RPT), collet connectors, gantry sleds, pipe lifters (PLF) and vertical...
