The invention discloses a method and device for sleeving a central air-conditioning capillary tube with a heat shrink tube. The method comprises the following steps: (1) clamping the outer surface at one end of the heat shrink tube by using a clamp; (2) putting the capillary tube on the surface of a V-shaped track, and aligning the center of the capillary tube to the center of the heat shrink tube; (3) driving the capillary tube to move to the clamp through a first driving device, and inserting the capillary tube into the heat shrink tube. The technical scheme is reliable in mechanical structure, simple in action and capable of greatly improving the production efficiency and reducing the labor strength.

The invention relates to an underground repetitive shock irritation device and shock irritation method for oil and gas well drilling. The underground repetitive shock irritation device is characterized by comprising an outer cylinder of which the middle part is provided with a shoulder, an upper connector is inserted inside the outer cylinder, and the upper connector is connected with an upper opening of the outer cylinder; a spring which is connected with an impact hammer is sleeved between the middle part of the upper connector and the outer cylinder, and a sleeve is clamped between the impact hammer and the outer cylinder in a sliding way; three structure slots on each of which an arc card is clamped are uniformly distributed on the upper part of the sleeve, and a thrust collar is sleeved at the lower part of each of the structure slots; a stop collar is arranged on the inner wall of the outer cylinder below the thrust collars; a circle of anvil is arranged at the middle part of the inner diameter of the sleeve, a plurality of communicating holes are arranged along the vertical direction of the anvil, an operating sleeve is sleeved on the inner diameter of low-half sleeve in a sliding way, and the operating sleeve is connected at the tail end of the upper connector; a circle of convex plate is arranged at the periphery of the upper opening of the operating sleeve; an external spline which is in sleeve connection with a connector of an internal spline is arranged at the outer diameter of the low-half sleeve, and a lower opening of the outer cylinder is fixedly connected with the connector of the internal spline; and the tail end of the external spline is connected with a lower connector. The repetitive shock irritation device and the shock irritation method disclosed by the invention can be widely used underground repetitive shock irritation in oil and gas well drilling operations in which signals are required.

The invention discloses a corner supporting thin-wall shell structure which comprises a shell structure body. The shell structure body is formed by connecting a plurality of panels. Connecting corners of every three adjacent panels are connected through a corner supporting component, the corner supporting components comprise corner supports, each corner support comprises three intersection faces, each intersection face is provided with a connecting hole position, and every three panels are fixedly connected with the corresponding three intersection faces through bolts. Through the corner supporting structure, the overall rigidity of the thin-wall shell structure can be improved, the relative position relation between the panels of a shell can be guaranteed, the number of screw holes in the outer surface can be reduced, the appearance is made to be changeable, and the period feel is achieved.
