  • Patent number: 11976429
    Abstract: The present invention discloses a shed tunnel structure for preventing a falling rock, including a shed tunnel body and a buffer plate for bearing impact of the falling rock, where the shed tunnel body includes a first supporting structure, and the first supporting structure is arranged on a side away from a ramp; one end of the buffer plate is connected to the ramp; a side face of the buffer plate close to the shed tunnel body is in movable contact with the first supporting structure, and the contact position is close to the other end of the buffer plate. The objective of resisting continuous impact of the falling rock can be achieved through the structural design.

  • Publication number: 20240117903
    Abstract: An ultrahigh-pressure acid-fracturing isodiametric hose assembly, comprising a hose body and a metal joint. The metal joint comprises an inner tube, a first outer tube the inner tube, and a second outer tube. The first outer tube and the second outer tube each is an independent pressing part. An external groove is provided at an outer wall of the inner tube. An end of the first outer tube comprises an internal ridge which matches the external groove for snapping. The terminal of the inner tube comprises a connecting portion. An outer wall of the inner tube comprises a first protrusion, and an inner wall of the first outer tube comprises a second protrusion engaging with the first protrusion. The hose body is clamped between the first protrusion and the second protrusion that are engaged. An inner wall of the second outer tube comprises multiple micro-protrusions.
