The invention belongs to the technical field of transmission assembly and particularly relates to a transmission countershaft key and pin full-automatic press-fitting unit comprising a body, a press-fitting device, an elastic cylindrical pin separating mechanism, an elastic cylindrical pin conveying mechanism, a key feeding mechanism, and a key conveying mechanism; the press-fitting device, the elastic cylindrical pin separating mechanism, the elastic cylindrical pin conveying mechanism, the key feeding mechanism and the key conveying mechanism are mounted on the body. A plurality of elastic cylindrical pins to be press-fitted are separated by the elastic cylindrical pin separating mechanism and then fall into the elastic cylindrical pin conveying mechanism; the elastic cylindrical pin conveying mechanism conveys the elastic cylindrical pins to be above a transmission countershaft positioned on the body; the elastic cylindrical pins are press-fitted into pinholes of the transmission countershaft by the press-fitting device; keys to be press-fitted fall into the key conveying mechanism through the key feeding mechanism; the key conveying mechanism conveys the keys to be above the transmission countershaft; the keys are press-fitted into key grooves of the transmission countershaft by the press-fitting device. The transmission countershaft key and pin full-automatic press-fitting unit has the advantages that assembly precision is guaranteed, labor intensity is reduced for operators, and assembly efficiency is improved.

The invention belongs to the technical field of ship design and research, and in particular relates to a working ship for detecting chemical weapons left over from Japan, which can work in inland waterways and offshore waters. It includes a deck body, two floating bodies, a cabin, a hand winch, two lockers and a workbench; the deck body is mainly composed of deck a, deck b, deck c and deck d, and the cabin is a detachable structure; The invention has the following advantages: the new design of the auxiliary floating body increases the wind and wave resistance of the working boat; the whole structure adopts a modular assembly structure, which is convenient for transportation and convenient and quick to assemble; in addition to the detection of Japanese abandoned chemical weapons in the waters, it can also be widely used for other purposes work boat.

The invention provides a lift well framework and a mounting method. The well framework comprises multiple door region modules, multiple well wall modules and a vertical column structure, wherein the vertical column structure forms a quadrate framework respectively through four vertical columns along the longitudinal direction; the multiple well wall modules are connected in sequence to form a closed space; the well wall modules are arranged between the vertical columns; the door region modules are arranged on the vertical column structure; and the quadrate framework is of an aluminum alloy structure. By the adoption of the technical scheme, the mounting difficulty and the mounting cost of a well lift can be effectively reduced; furthermore, the connection modes are consistent, so that theoverall beauty of the well framework is improved; by use of the aluminum alloy well framework, the problem of neglected installation or mis-installation of well lifts is avoided; and the mounting quality of the well lift can be effectively controlled.

The invention provides a vertical electrophoresis tank and an electrophoresis apparatus. The vertical electrophoresis tank comprises a slide assembly, a gel frame assembly and a groove body assembly,wherein the slide assembly comprises a large slide and a small slide used for forming a gel preparing cavity, and a lateral opening groove communicated with the bottom of the gel preparing cavity is formed in the large slide; the gel frame assembly comprises a gel frame, a concave sealing member, a first negative electrode conduction member and a first positive electrode conduction member; the groove body assembly comprises a groove body, a pressing mechanism, a second negative electrode conduction member and a second positive electrode conduction member. The conduction of an electrode and thepressing of the slide assembly are synchronously completed by the pressing mechanism to eliminate the single operation of locking and inserting positive and negative electrodes sequentially in the slide assembly of traditional electrophoresis equipment to prevent the leakage of electricity and electric shocks; gel preparing and electrophoresis are completed in the vertical electrophoresis tank, additional gel preparing auxiliary devices are not needed, occupied space of electrophoresis testing equipment is saved, the operation is easier, and externally dripping gel liquid in the gel preparingprocess is accumulated in the groove body, so that the cleanliness of a testing tabletop is improved.

The invention relates to a three-phase conductor commutation joint, which comprises a sealing cylinder body and sealing flanges installed at both ends of the sealing cylinder body. The two sealing flanges are respectively provided with three transfer inserts, and the transfer inserts on the two sealing flanges are The inserts are arranged along the straight line with the same extension direction; there are three-phase conductors in the sealing cylinder, and the two ends of the three-phase conductors are respectively connected to the three transfer inserts on the two sealing flanges; the three-phase conductors are located on both sides Each of the two-phase conductors has a bent section, so that the two ends of each phase conductor in the two phase conductors are respectively connected to two transfer inserts on the two sealing flanges on both sides of the axis of the sealing cylinder. Such setting can realize the phase sequence interchange of A and C phases under the condition that the three-phase arrangement at both ends of the three-phase conductor commutation connector is the same. In actual use, the three-phase conductor reversing connector can be directly installed on the equipment. At the three-phase interface, the phase sequence exchange of A and C phases is realized, so as to realize the connection of three-phase equipment with different phase sequences.
