Embodiment Construction
[0015] Combine below figure 1 , 2 , 3, 4 describe an embodiment of the present invention.
[0016] A blowout preventer ram body guide structure includes two ram bodies 1 that move relative to each other and have identical structures, and radial grooves 2 are provided on the inner end surfaces of the ram bodies 1 . Two symmetrical guide surfaces 3 and two symmetrical guide plates 4 protrude from the inner end surface of the gate body 1, and the two symmetrical guide surfaces 3 and two symmetrical guide plates 4 are respectively located in the radial concave On both sides of the groove 2; the two guide surfaces 3 and the two guide plates 4 are arranged alternately in the circumferential direction, and the end faces of the guide surfaces 3 and the guide plates 4 on the same side of the radial groove 2 respectively form two "V" Type guide structure; the inner end surface of the gate body 1 has two symmetrical arc-shaped notches 6 for accommodating the opposite guide surface 3, a...

The invention discloses a BOP (Blowout Preventer) gate plate body guiding structure. The BOP gate plate body guiding structure comprises two gate plate bodies which are in opposite movement and identical structures, wherein the inner end surface of each gate plate body is provided with a radial groove and is provided with two symmetrical guiding surfaces and two symmetrical guiding plates in a bulging way, and the two symmetrical guiding surfaces and the two symmetrical guiding plates are respectively positioned at two sides of the radial groove and are alternately arranged in the circumferential direction; two V-shaped guiding structures are respectively formed by the end surfaces of each guiding surface and each guiding plate which are positioned at the same side of the radial groove; the inner end surface of each gate plate body is provided with two symmetrical arc-shaped notches which are used for containing the opposite guiding surface and two symmetrical strip-shaped notches which are used for containing the opposite guiding plates; the inner sides of the guiding surfaces and the guiding plates are all provided with arc-shaped grooves, and a cable groove is formed by the opposite arc-shaped grooves after the two gate plate bodies are meshed. According to the BOP gate plate body guiding structure disclosed by the invention, the problems that a cable cannot be reliably guided in a sealing groove when a BOP gate body is closed, and thus the cable is injured or pinched off are effectively solved, the structure is simple, the performance is reliable, the strength is high, and the cost is low.
Description
technical field [0001] The invention belongs to the technical field of oil field logging and perforating equipment, and in particular relates to a guide structure for a blowout preventer ram body. Background technique [0002] During wireline operations such as well logging and perforation, if abnormal conditions occur, it is necessary to close the blowout preventer to seal the wellhead. The existing BOP ram only has a guide structure on one side. Since the cable will bend, the cable cannot be guided on the non-guided side. When the BOP ram body is closed, the cable cannot be reliably guided into the sealing groove, which is likely to cause pinch Accidents that may injure or pinch cables. In addition, some guide structures and ram bodies are fixedly connected by bolts or welding, and there is a hidden danger of loosening or falling during use. Once the guide block is loose and falls underground, it will be very difficult and costly to salvage. Contents of the invention ...
