Description

Technical Field

[0001] The utility model relates to the technical field of offshore oil exploration equipment, in particular to an assembly of a main shaft body and a main body for preventing biting. Background Art

[0002] Offshore oil exploration equipment generates huge vibration waves and collects feedback waves from the seabed to analyze the seabed structure and material distribution. The spindle head and the main body are used to stimulate and transport high-pressure gas.

[0003] In the existing technology, the main bodies are assembled by screwing together, and there is a section of stainless steel metal surfaces that are matched together, with a gap of only 0.05mm. Figure 2 As shown, these two structures are prone to slight deformation after high-pressure vibration, which can cause the threads to get stuck and the metal surfaces to get stuck, making it impossible to remove the main body from the spindle head, affecting subsequent maintenance and repair. Utility Model Content

[0010] The external threads of the main body of the utility model are copper-plated to prevent the threads from biting, and at the same time, an anti-bite bushing is added to prevent the spindle head and the main body from biting, which makes it impossible to disassemble and repair them, thereby increasing the service life and reducing the difficulty of maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic diagram of the structure of an embodiment of the utility model;

[0012] Figure 2 It is a schematic diagram of the background technology structure of an embodiment of the utility model. DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and examples, but the examples are not intended to limit the utility model.

[0014] like Figure 1 As shown, the embodiment of the utility model comprises a spindle head 1, a main body 2 and an anti-seize bushing 3, and the spindle head 1 and the main body 2 are connected via the anti-seize bushing 3.

[0015] In this embodiment, the inner hole of the spindle head 1 of component No. 1 has an internal thread, and the outer circle of the end of the main body 2 of component No. 2 has an external thread, and the external thread is copper-plated. Since the spindle head 1 of component No. 1 and the main body 2 of component No. 2 are made of stainless steel, the threaded connection between the stainless steel of the spindle head 1 and the stainless steel of the main body 2 is easy to bite when subjected to high-pressure vibration. The copper plating of the external thread of the main body 2 of component No. 2 can play a lubricating role and prevent it from biting with the inner hole thread of the spindle head 1 of component No. 1. Slots are made on the outer circle of the main body 2 of component No. 2, and an anti-bite bushing 3 of component No. 3 is added, which adopts an anti-bite bushing made of polyoxymethylene. The spindle head 1 of component No. 1 and the main body 2 of component No. 2 produce slight deformation under high-pressure vibration, which will cause the metal surfaces to bite each other. Add anti-bite bushing 3 of component 3. When the spindle head 1 of component 1 and the main body 2 of component 2 are slightly deformed, polyoxymethylene is soft and elastic, so it can be squeezed and stretched under the condition of slight deformation, so that the spindle head 1 of component 1 and the main body 2 of component 2 will not be stuck between the metal surfaces due to slight deformation, and can be smoothly disassembled under the expansion and contraction of anti-bite bushing 3 of component 3, which provides convenience for subsequent maintenance of the equipment. The equipment will not be scrapped due to being stuck and unable to be disassembled.

[0016] In this embodiment, the marine petroleum geological exploration equipment needs to generate strong vibration waves to realize geological exploration. The anti-seizure spindle head and main body of the present invention are part of the marine petroleum geological exploration equipment. The spindle head and main body are devices used to excite and transport high-pressure gas. During use, the strong vibration waves will cause slight deformation to the spindle head and main body exposed to the seawater. The tightly fitting threads and contact surfaces will be stuck due to slight deformation and cannot be disassembled. The external threads of the main body are copper-plated to prevent the threads from biting. At the same time, an anti-bite bushing is added to prevent the spindle head and the main body from biting, which makes it impossible to disassemble and repair, thereby increasing the service life and reducing the difficulty of maintenance.
