The invention discloses an automatic steel pipe cleaning machine with steel pipe supporting and guiding functions, and belongs to the field of metal pipe cleaning machines. The cleaning machine comprises a cleaning fluid box, a motor, a shaft sleeve transmission wheel, a brush pipe, a circulating fluid supply mechanism and a pair of steel pipe supporting and guiding frames, wherein a bearing pedestal fixing plate and a motor supporting plate are arranged on an opening in the upper portion of the cleaning fluid box; the motor is arranged on the motor supporting plate, and a shaft sleeve is fixed to the center of the shaft sleeve transmission wheel and supported by a shaft sleeve bearing pedestal; the brush pipe is fixed to the shaft sleeve, a brush locating groove is formed in the inner wall of a brush pipe cavity, and a brush is arranged in the brush locating groove; the circulating fluid supply mechanism is arranged in a cleaning fluid box cavity; the steel pipe supporting and guiding frames are located in the same axial line as the brush pipe and fixed to the outer wall of the left end of the cleaning fluid box and the outer wall of the right end of the cleaning fluid box, adjustment grooves are formed in the lower portions of the steel pipe supporting and guiding frames respectively, and the upper portions of the steel pipe supporting and guiding frames form a supporting and guiding cavity. The cleaning machine is small in size, flexible in arrangement and low in cost, and can protect an operator and reduce labor intensity; cleaning fluid can be used as a cooling lubricating agent when workpieces are machined by a machining center or a numerically-controlled machine tool of a machine manufacturing company.

The invention discloses a reducer anti-torque structure of a medical robot. A positioning shaft is arranged beside a reducer and rotationally connected with a pitching arm; the positioning shaft and a rotary base are fixed; a torsional spring base is installed on the positioning shaft and sleeved with a torsional spring; an inner hook of the torsional spring is connected with the torsional spring base; and an outer hook of the torsional spring is connected with the pitching arm. The torque of the reducer is balanced through the torsional spring, so that on the one hand, a mechanical arm of the medical robot is effectively prevented from sliding off, and the potential safety hazard is eliminated; on the other hand, torque, size and motor power of the reducer are reduced properly, so that the overall size is reduced, and the cost is effectively saved; and meanwhile, after the torsional spring is additionally arranged, when a motor is out of control suddenly, the torsional spring can achieve the buffering function, and the risk is effectively reduced. The reducer anti-torque structure of the medical robot has the characteristics of being reasonable in design, simple and compact in structure, easy to assemble, safe, reliable, easy to modify, low in modification cost, and the like, and can be applicable for various medical robots.

The invention discloses a structure and method for reducing the pile length of a deep soft soil layer by forming a composite foundation. The structure comprises a casing pipe; the casing pipe comprises a casing pipe outer wall, a casing pipe inner wall, an overflow hole, a pressure chamber and a grouting opening; the pressure chamber is formed between the casing pipe outer wall and the casing pipeinner wall; a grouting system is vertically distributed on the outer wall of the pressure chamber; a grouting pipe is inserted into the grouting opening in a pressure chamber top board on the top ofthe pressure chamber and injects mortar into the pressure chamber; and the mortar flows out of the casing pipe outer wall through the overflow hole formed in the pressure chamber to be mixed with softsoil to form the composite foundation. According to the structure and method for reducing the pile length of the deep soft soil layer by forming the composite foundation, the mortar and the soft soilfoundation are mixed to the composite foundation, the foundation soil property is improved, the bearing force of the foundation is improved, friction resistance between a friction pile and the foundation is increased, accordingly the pile length of the friction pile is effectively reduced, the materials are saved, the cost is reduced, and at the same time, the casing pipe also achieves the supporting function, hole collapse is prevented, and the structure has very important significance for foundation engineering.

The invention provides a vaccine quick pick-and-place device, which belongs to the technical field of preventive medicine. The technical solution is: a quick pick-and-place device for vaccines, including a refrigerator box and a door hinged with the refrigerator box, a channel is arranged on the top of the refrigerator box, a box cover is arranged on the channel, and the box body of the refrigerator is It is equipped with a pick-and-place mechanism. The beneficial effects of the present invention are: when taking the vaccine, the present invention does not need to open the door of the refrigerator, even if the channel on the refrigerator body is opened, cold air will not continuously flow out of the refrigerator, which facilitates the storage of the vaccine.
