The utility model discloses a bearing penetrates cover and bearing assembly for dry -type continuous casting, this bearing penetrates cover includes: the whole is hollow's cover body of gyroid, the cover body has opposite first side and second side along the first direction, the first side forms the through -hole of variable aperture to the second side, the through -hole includes first hole section and second hole section who set up in order from the first side to the second side, the inner diameter of first hole section is less than the inner diameter of second hole section, the inner wall of first hole section is opposite and forms the sealing groove, the outer surface of cover body is provided with the lap joint, the bearing penetrates cover is used for embedding installation in the bearing seat, and the lap joint is used for abutting in bearing seat, penetrates the cover sealing piece, the cover sealing piece is metal sealing piece, and the cover sealing piece installs in sealing groove. The application can effectively improve the reliability of bearing penetrates cover when using, and then improve the service life greatly.

This utility model discloses a raft-type liftable aerator, relating to the field of aerator technology. The utility model includes plastic floats, elbows, tees, connectors, aeration risers, an aerator body, and steel wire ropes. Two floats are provided, and several elbows are provided, with the two floats connected by the elbows. By using two floats connected by several elbows and then joined by the connector to form a raft, the stability of the aerator body is increased. Four steel wire ropes are used to fix the entire raft, adding two more steel wire ropes than the single float of the original suspended chain aeration system, further reducing the swaying amplitude of the floats on the water surface. By replacing the hose (snake-skin hose) connection between the floats and the aerator body with a connector that connects to the aerator body via the aeration riser (which is a rigid pipe), tangling of the hose (snake-skin hose) is avoided, preventing tangling from affecting the equipment's performance and maintenance.

This utility model discloses an anti-aging, high-ductility PVC sheet production equipment, relating to the field of PVC sheet production. It includes a main body of equipment and PVC sheets. The inner wall of the main body is equipped with a cleaning mechanism, which includes a first cleaning roller and a second cleaning roller rotatably mounted on the inner wall of the main body. A first end-face gear is fixedly mounted at the end of the first cleaning roller, and a second end-face gear is fixedly mounted at the end of the second cleaning roller. A drive motor is fixedly mounted on the outer wall of the main body, and a drive shaft is fixedly mounted at the output end of the drive motor, with a drive gear fixedly mounted at the end of the drive shaft. A pressing mechanism is provided at the end of the second cleaning roller. This anti-aging, high-ductility PVC sheet production equipment can simultaneously perform dust removal on both the upper and lower surfaces of the sheet, forming a double-sided cleaning structure. Compared to traditional single-sided cleaning methods, it can more comprehensively remove dust adhering to the sheet surface, avoiding dust residue affecting sheet quality and subsequent use.

This invention discloses a water tank replenishment device for aviation operation support, including a base fitted around a fire hydrant. A protective mechanism is provided on the outside of the base, comprising a frame positioned on top of the base and fitted around the fire hydrant. A lead screw is provided on the outside of the base, with a threaded sleeve threaded to its outer surface. A cleaning component is provided on the outside of the threaded sleeve. A bracket is rotatably connected to the outer surface of the lead screw. This invention relates to the technical field of aviation operation support equipment and solves the problems of existing aviation operation support water tank replenishment devices, where the protective frame is supported and fixed by a fixing plate to protect the fire hydrant. The fixing plate has poor support performance and is prone to detachment. Furthermore, both the support and operation require manual intervention, which is cumbersome, inefficient, and inconvenient for fire hydrant use.

The utility model discloses a kind of transmission devices of mine rapid-setting injection material, including equipment shell, the inside installation of equipment shell has feeding assembly, the front side of equipment shell is equipped with the transmission assembly for realizing drive feeding assembly, the bottom of equipment shell is fixed with four groups of support columns at equidistance, the side of support column is installed with transport assembly, feeding assembly includes four groups of sliding slot symmetrically opened in the inner wall of equipment shell, the inner wall of four groups of sliding slot is slidably connected with slider, the top of four groups of sliders is fixedly connected with spring, the end of four groups of springs away from slider is fixedly connected with the inner wall top of sliding slot, the side of four groups of sliders is fixedly connected with filter screen, the bottom of slider is fixed with four groups of lugs at equidistance symmetry, the utility model can prevent rapid-setting material from accumulating when mixing and stirring, affect subsequent stirring and use.

The utility model discloses a plate stacking lifting platform which comprises a base, a shear fork arm arranged on the upper side of the base, a driving hydraulic cylinder matched with the shear fork arm and arranged on the upper side of the base, a bearing platform arranged on the upper side of the shear fork arm, a driving cavity formed in the bearing platform, and a plurality of tightening openings formed in the inner wall of the driving cavity. According to the device, the driving mechanism, the tightening blocks, the positioning blocks, the alignment plates and other components are arranged, the multiple tightening blocks can be driven by the driving mechanism to move towards the close direction, the multiple alignment plates are pulled to be tightened while the tightening blocks move towards the close direction, and then the periphery of a plate is tightened and positioned; according to the plate stacking device, tiny deviation generated during placement can be automatically corrected after the plates are stacked, it is ensured that the stacking positions of the plates are kept consistent, the plate stacking quality is effectively improved, and the situation that subsequent use, transportation and other links are affected due to accumulation of position differences is avoided.
