Problems solved by technology

The biggest shortcoming of this crimping method is that the internal intubation leads to a large loss of the diameter of the pipe, which makes the selection of the pipe (diameter) too large, which not only relatively increases the cost of the pipe, but also increases energy consumption due to the increase in flow resistance;
[0005] For high-pressure thick-walled and large-diameter fiber-reinforced pipes, the single shrinkage of the multi-lobe die head provides uneven circumferential grip to the pipe, which will cause fiber damage in the reinforcement layer, making the fibers unable to function 100%;
[0006] This crimping method has high requirements on the consistency of joint material properties (even different workers may have different results), which can easily cause inconsistent crimping grip (uneven axial and circumferential grip), and lead to a serious problem. Leakage due to seal failure

Embodiment 1

[0035] Such as figure 1 A portable on-site crimping device is shown, including a support connecting plate 1, a rotating mechanism 5 fixedly connected to one side of the supporting connecting plate 1, a connecting rod 4 is movably connected to the rotating mechanism 5, and the rotating mechanism 5 drives the connecting rod 4 to move, the end of the connecting rod 4 passes through the support connecting plate 1 and is fixedly connected with the internal expansion head 7 on one side of the supporting connecting plate 1; the supporting connecting plate 1 is used as the basis of the whole device and supports The shape of the connecting plate 1 is not limited in detail, and the supporting connecting plate 1 can be fixedly connected to the bracket for use according to the environment used on site. A central hole penetrating the supporting connecting plate 1 is provided on the supporting connecting plate 1 to ensure The connecting rod 4 can be driven by the rotating mechanism 5 to fre...

Embodiment 2

[0044] On the basis of Example 1, when fastening the wire-tip core tube assembly 2 and the sleeve 3 to the supporting connecting plate 1, it is necessary to carry out the fastening stably, and at the same time, it is convenient to disassemble it after the crimping is completed. For this reason Figure 5 The side of the supporting connecting plate 1 is provided with a clamping device 9 for clamping the casing 3 and the thread core tube assembly 2 . The clamping device 9 can conveniently clamp the sleeve pipe 3 and the threaded core tube assembly 2, specifically, it is convenient to clamp the threaded core tube assembly 2 on the support connecting plate 1, and combine the threaded core tube After the fastening of the body 2 is completed, the matching sleeve is set on the wire head core tube assembly 2 to complete the fastening;

[0045] Specifically, when crimping the pipeline, there are several standards for the pipe diameter of the wire end core tube assembly 2. In order to e...

Embodiment 3

[0047] On the basis of Embodiment 1, the rotating mechanism 5 needs to drive the connecting rod 4 to move laterally, so as to ensure that the internal expansion head on the pull rod can be driven to perform internal expansion work, such as image 3 and Figure 4 The rotating mechanism 5 includes a rotating body 501 fixedly connected to the supporting connecting plate 1, a driving screw nut 502 arranged in the rotating body 501, and the driving screw nut 502 is threadedly connected with the connecting rod 4, and the driving wire The lever nut 502 is movably connected to the rotating body 501 through a bearing 503. A worm gear 504 is fixedly sleeved on the driving screw nut 502. The worm gear 504 is meshed with a worm 505, and the end of the worm 505 is fixedly connected with a driving device 506. ; The driving device 506 is a driving motor.

[0048] The power consumption of the drive motor can be based on the situation on site, using municipal power, and can also provide power...

Abstract

The invention relates to a portable on-site buckling device and buckling method. The device comprises a support connecting plate and a rotating mechanism. A connecting rod is movably connected to therotating mechanism, and the end portion of the connecting rod penetrates through the support connecting plate and is fixedly connected with an inner expansion head arranged on one side of the supportconnecting plate. The rotating mechanism drives the connecting rod to move, the inner expansion head is driven to perform inner expansion extrusion on a composite pipe and a thread head and core pipecombined body placed in a casing pipe. A sleeve, the thread head and core pipe combined body and the composite pipe are buckled together, buckling can be carried out on site, the buckling efficiency is improved, and the problem that the buckling strength is inconsistent (axial and radial grip strength is not uniform), and reinforcing fibers are damaged is solved, the application reliability of thepipe is improved, the inner expansion enables the effective drift diameter of a joint to be relatively expanded, the pipeline flow resistance is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of butt jointing of flexible high-pressure delivery pipes, in particular to a portable on-site crimping device and a crimping method. Background technique [0002] Flexible composite high-pressure transmission pipes are mainly used for land oil and gas transmission pipelines. They are corrosion-resistant and easy to operate. They reduce transportation costs and improve production efficiency, laying a foundation for the promotion of non-metallic pipelines in this field. It can be said that it is a new development branch of future oilfield pipelines and has broad application prospects. [0003] However, it is reported that some problems and deficiencies were also found during the application process, mainly manifested in pipe burst and leakage. The causes of pipe failure include pipe quality problems, joint problems, and work specification problems, among which the problems caused by joint technology account ...
