This application belongs to the field of hydro-generator installation and discloses a stator core slot clamping device for hydro-generators with measuring function. It includes a support cylinder and an insert block disposed at the front end of the support cylinder. The first end face of the insert block has outwardly extending lugs on both sides, and the opening formed by the lugs and the first end face mates with the slot opening of the hydro-generator stator core slot. A measuring scale is provided on the outer side of the insert block. A pressure sensor is provided on the inner side of the first end face of the insert block. A threaded through hole is provided in the middle of the insert block, and a screw rod is provided inside the support cylinder. The screw rod passes through the threaded through hole and is threadedly connected to the insert block. This reduces the difficulty of clamping the stator core wires in the hydro-generator and improves installation efficiency. The pressure sensor, in conjunction with the measuring scale, can determine whether the stator wires are clamped firmly and tightly against the bottom surface of the core slot, solving the problem that the stator wires are not easily fully lowered to the bottom of the stator core slot during installation, thus affecting the installation of the slot wedges.

This invention provides a casting process for fixing markings on high-manganese steel frogs. A support block is fitted between the marking sand mold on the side of the model rail wall and the bottom of the model rail wall within the sand box. The marking sand mold has a special cross-sectional structure to prevent displacement. One side of the marking sand mold is tightly attached to the model rail wall; the lower side is supported and fixed by the support block; and the surrounding area is tightly wrapped with molding sand. After hardening and demolding, the support block area is filled and solidified with molding sand to ensure that the marking sand mold and the model rail wall remain coplanar. This reduces the amount of grinding required due to non-coplanarity between the marking sand mold and the model rail wall, and also standardizes the position of the markings on frogs of the same model. This invention solves the technical problems of marking sand mold displacement and excessive grinding of the markings on the castings; the markings on the cast frogs of the same model are standardized and neat, making it suitable for widespread application.

This invention discloses an intelligent bed, including a bed frame, a mattress, a pillow, a pillow drive mechanism, and a control system. The pillow has a head support area and a neck support area at its top. A frame is installed inside the pillow, and the frame includes a neck support section. The pillow drive mechanism includes a mounting base, a rotary drive device, and a rotating shaft. An eccentrically positioned swing member is sleeved on the rotating shaft. The top of the swing member is connected to the bottom of the frame. The rotary drive device drives the rotating shaft to rotate back and forth at a certain angle via a transmission component, which in turn drives the neck support section to swing up and down via the swing member. A detachable strap is attached to the pillow. The control system has a cervical spine anti-arch traction mode. In this mode, the first lifting mechanism and the pillow drive mechanism simultaneously reciprocate to achieve anti-arch traction correction of the neck by the neck support section. The detachable strap ensures that the neck is in close contact with the neck support area, improving the massage effect of the cervical spine anti-arch traction.

The application discloses a kind of plasma arc welding equipment with smoking function for medical instrument processing, it is related to medical instrument welding relevant technical field, in traditional technology, for the welding process of medical instrument with smoking function, gas is ejected from welding site, gas will quickly drift away from welding site, thus causing gas waste, and in the welding process, high-temperature welding slag produced will also be blown by gas and splash, easily hurt operator;And the device forms a semi-closed welding area by the protective shell main body in the protection mechanism and the movable protective shell, forces the inert or active gas ejected by welding module to slowly dissipate from both ends, rather than quickly drift away, greatly reduces gas consumption, optimizes gas utilization rate, limits welding slag inside the protective shell, this closed environment avoids the harm of welding slag splashing to operator, especially when high-frequency welding medical instrument, reduces safety risk.
