The invention discloses a steel pipe polishing equipment, which comprises a steel pipe polishing equipment body. A main valve of a polishing motor is arranged in the main body of the steel pipe polishing equipment; a polishing handle is arranged on the main valve of the polishing motor; The valve is provided with a rotating roller; the front end of the rotating roller is provided with polishing bristles; one side of the rotating roller is provided with an outer throwing roller; a clamping spring is arranged between the outer throwing roller and the rotating roller; The outer throwing roller is provided with an outer throwing brush; a symmetrical magnet is arranged between the outer throwing brush and the polishing bristles; a polishing wheel is arranged on the outer throwing brush and the polishing bristles; the polishing The grinding wheels are arranged in a figure-eight shape. Its structure is simple, easy to use, and easy to operate. It can realize the polishing of the outer surface and the inner wall. The polishing is fast and uniform, with high efficiency and convenient use.

The invention discloses a full-automatic interval shifting mechanism which comprises a bottom plate. A rodless air cylinder is fixed to the bottom plate. A carrying plate is fixed to a sliding block of the rodless air cylinder. A sliding rail is fixed to one side of the carrying plate. The sliding block is inserted on the sliding rail in a sleeving manner and fixed to the bottom face of a stirring paw installation plate. A pushing air cylinder is fixed to the other side of the carrying plate. The end of a push rod of the pushing air cylinder is fixed to a connecting part of the bottom face of the stirring paw installation plate. A proximity switch is arranged on the rear part of the carrying plate and corresponds to the rear side wall of the carrying plate. A plurality of stirring paws are fixed to the top face of the stirring paw installation plate. A transverse sliding rail is fixed to the bottom plate. A transverse sliding block is fixed to the carrying plate and inserted on the transverse sliding rail in a sleeving manner. An induction piece is fixed to the bottom face of the stirring paw installation plate. Two photoelectric sensors are fixed to the parts, close to the left side and the right side, of the bottom plate and correspond to the induction piece. The full-automatic interval shifting mechanism can automatically move a product machined at one position to a station at another position to be machined, and thus the manual cost and the working intensity are lowered.

A flow direction control device of heating stream and cooling stream is prepared as connecting said device separately to the first heat exchange unit, the second heat exchange unit, air conditioner and compressor for controlling heated working fluid from the first heat exchange unit to be sent to air conditioner for being used as the first heat media or to be sent to the second heat exchanger for being condensed there then to send it to air conditioner for being used as the second cooling media in order to make air conditioner output hot and cold alternatively, enabling to set heating course on the first heat exchange unit for providing the third heat media out.

The invention discloses a credit text analysis method and a credit object auditing method and device, and relates to the technical field of knowledge maps. A specific embodiment of the method comprises the steps of obtaining a target credit card text, wherein the target credit card text comprises at least one target element; a target semantic template corresponding to the target credit document text is obtained, the target semantic template comprises a statement template and an upper sharing hierarchy of the statement template, the statement template comprises at least one target slot position, and the target slot position corresponds to the target element; obtaining a full-link slot position of the target credit card text according to the statement template and the upper sharing hierarchy; and matching the target semantic template with the target credit text to obtain a target slot value corresponding to the full-link slot position. According to the implementation mode, the slot position and the slot value corresponding to the element in the credit card can be automatically obtained, and the related content in the credit card text can be analyzed.
