The utility model relates to the technical field of laser cutting, and discloses a four-chuck groove pipe cutting machine which is characterized in that a first limiting plate is arranged on a first chuck structure, a second limiting plate is arranged on a second chuck structure, a third limiting plate is arranged on a third chuck structure, and a fourth limiting plate is arranged on a fourth chuck structure; a first buffering seat, second buffering seats, third buffering seats and a fourth buffering seat which are arranged in the Y-axis direction are arranged on the lathe bed, the first limiting plate reciprocates between the first buffering seats, the second limiting plate reciprocates between the two second buffering seats, and the third limiting plate reciprocates between the two third buffering seats. And the fourth limiting plate reciprocates between the two fourth buffer seats. The multiple buffer seats are arranged on the lathe bed, the limiting plates corresponding to the buffer seats are arranged on the chuck structures, the moving paths of the limiting plates are limited between the two buffer seats, and the limiting plates correspond to the chuck structures, so that the moving paths of the chuck structures can be limited.

The utility model belongs to the field of cranes, particularly relates to a crane main beam turnover mechanism, and aims to solve the problem that crane main beams on the two sides need to be rotated respectively in the prior art, so that the crane main beam turnover mechanism is easy to desynchronize. The number of the supporting seats is four, and the four supporting seats are connected to the top of the base through bolts; the four crane main beam overturning assemblies comprise supporting barrels, six electric push cylinders and six clamping plates, the surfaces of the supporting barrels are rotationally connected with the interiors of the supporting seats in a sleeving mode, the power mechanism can synchronously drive the four supporting barrels to rotate through transmission of the structure, and the four supporting barrels can synchronously rotate through transmission of the structure; the four supporting cylinders are arranged on the two sides of the surface of the crane main beam in a sleeving mode correspondingly, so that the supporting cylinders can drive the left part and the right part of the crane main beam to stably and synchronously rotate, the difference of the rotating speeds of the supporting cylinders is avoided, and the situation that welding parts are torn due to the different rotating speeds can be avoided.

The utility model discloses a constant temperature storage device for ram semen, and relates to the technical field of frozen semen constant temperature equipment, including the heat preservation box, adjustable support leg and the universal wheel of rotation installation are fixedly installed in the bottom of heat preservation box, the heat preservation cover plate is fixedly sealed and installed at the top of heat preservation box, and a plurality of mounting hole slots are formed in the heat preservation cover plate, the mounting hole slot is used for fixedly installing the storage mechanism, and the storage mechanism is used for zoning isolation ram semen, the compression spring is fixedly arranged on the heat preservation box bottom plate one end, and the other end is connected with the storage mechanism, use this semen storage device, through the storage mechanism, make multiple thumb tube all be in the same low temperature environment, form stable low temperature field, avoid the different storage environment of each thumb tube because of temperature difference, simultaneously, when taking out a thumb tube, avoid the large loss of liquid nitrogen and cause the temperature of heat preservation box to produce greater fluctuation.
