Description

Technical Field

[0001] The utility model relates to the technical field of wellhead operation, in particular to a pipe protector used for inspecting and repairing a wellhead. Background Art

[0002] Wellhead maintenance operations mainly involve the maintenance, modification and inspection of wellhead facilities to ensure that the wellhead equipment can operate normally to ensure production safety and efficiency.

[0003] During the wellhead maintenance operation, the wellhead cover will be opened. At this stage, the cables and equipment inside the wellhead will be carefully inspected to ensure that there is no obvious damage or fault. If problems are found with the cables and pipelines, they will be repaired or replaced according to the actual situation. During the replacement process, due to the lack of supporting and protective structures, the cables and pipelines are pulled and moved and there is wear on the sides of the wellhead, which can easily cause damage to the cables and pipelines and affect their subsequent use. For this reason, the present application proposes a pipe protector for inspecting the wellhead. Utility Model Content

[0011] Preferably, the elastic pulling member includes a fixed sleeve fixed on the slider and a connecting rod movably arranged at an end of the fixed sleeve away from the slider, the ring is fixedly installed on the end of the connecting rod extending out of the fixed sleeve, and a baffle is fixed on the end of the connecting rod extending into the fixed sleeve, and a second spring is arranged between the baffle and the inner end wall of the fixed sleeve away from the slider, and the second spring is sleeved on the connecting rod.

[0012] Preferably, the elastic buffer comprises a pair of fixed plates fixed on the side walls of the fixed arm, a sliding rod is fixedly connected between the pair of fixed plates, the sliding block is slidably sleeved on the sliding rod, and a first spring is sleeved on the sliding rods located on both sides of the sliding block.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model uses a collar arranged on one side of the fixed arm. After a pair of supporting members are used to support the fixed arm and the adjusting arm, a pipeline for wellhead maintenance passes through the collar, thereby achieving suspended support for the pipeline, thereby avoiding wear between the pipeline and the side of the wellhead. In addition, with the threaded sleeve cooperation between the adjusting arm and the screw rod, the adjusting arm can be driven to extend and retract relative to the fixed arm, thereby adjusting the spacing between a pair of vertical plates, and is suitable for wellheads of different sizes.

[0015] The utility model reduces the wear between the pipeline and the ring through the structural design of the circular cross-section of the ring, and the elastic support of the two sides of the slider by a pair of first springs and the elastic support of the connecting rod by the second spring can make the ring have an elastic limiting buffer effect on the pipeline, effectively reducing the wear of the pipeline caused by pulling during wellhead maintenance.
