The utility model discloses a contact network pole upper enclosure type bird preventing device is set up in the pole main part top of contact network electric pole, including the shield main part, the shield main part is the prism platform cylinder shape and is provided with with small top pole adaptation's upper forming mouth in the top, the bottom port of shield main part is buckled on the pole main part top end face.

The utility model relates to the technical field of screws, in particular to screw thread rolling equipment which comprises a supporting table, a supporting seat arranged on the side wall of the supporting table, an air cylinder arranged at the top of the supporting seat, a piston column arranged at the output end of the air cylinder, a first rolling plate arranged at the end, away from the air cylinder, of the piston column and a second rolling plate arranged on the side wall of the supporting table. The oil pumping assembly comprises a first connecting rod arranged at the bottom of the first washboard, a push rod arranged on the side wall of the second washboard and an inflator pump arranged at the end, away from the second washboard, of the push rod. Through the arrangement of the first connecting rod and the mounting box, when the first twisting plate drives screws to be machined on the second twisting plate, lubricating oil can be sprayed on the first twisting plate according to the repeated stretching action of the air cylinder, then the lubricating effect is kept when each screw is machined, the situation that the first twisting plate loses the lubricating effect, and consequently the machining efficiency of the screws is affected is avoided, and the machining efficiency of the screws is improved. And therefore, the overall machining effect of the screw is improved.

The application discloses a sulfuric acid production filtering tower structure and relates to the technical field of sulfuric acid production filtering, which comprises a tower body, filtering units and a vibration and liquid discharge mechanism, the inner wall of the tower body is provided with an upper mounting layer and a lower mounting layer, a plurality of filtering units are arranged in a circumferential manner between the upper mounting layer and the lower mounting layer, the filtering units comprise support assemblies and fiber bed layers, the support assemblies and the fiber bed layers are all in the shape of an inverted cone cylinder with the upper part being larger and the lower part being smaller, the support assemblies comprise inner support cages and outer support cages, and the side of the inner support cage facing the fiber bed layer is provided with spiral flow guide ribs, the vibration and liquid discharge mechanism comprises a flow guide piece and a lever piece, the flow guide piece comprises a plurality of shuttle-shaped flow guide bodies with tapered tips at the upper and lower ends, and the lever piece comprises liquid receiving hoppers corresponding to the flow guide piece. The application has the advantages that the filtering units and the spiral flow guide ribs can balance the load distribution of the fiber bed layers, reduce the coverage of the lower liquid film and improve the overall trapping efficiency; meanwhile, the vibration and liquid discharge mechanism is driven by the gravity of the acid liquid to generate periodic short vibrations, so that the acid liquid can be smoothly discharged.

The present application relates to the technical fields of hard alloy extrusion forming, and discloses a hard alloy extrusion forming device and method, which solves the problem that the ejection structure is easy to leave a pressure mark on the formed part when the ejection force is large, and secondary processing is needed in the later stage, and comprises a base, a rotating shaft is arranged above the base, the bottom end of the rotating shaft is connected with the base through a bearing, a support sleeve is arranged outside the rotating shaft, a bearing is arranged at the connection between the support sleeve and the rotating shaft, a support ring is arranged outside the support sleeve, the support ring and the support sleeve are connected through a plurality of first connecting plates, a plurality of lower dies are arranged above the base, a first connecting shaft is fixedly connected to the lower die, a fixing frame is arranged outside the first connecting shaft; the gravity of the formed part provides power for demolding, reduces the force of the magnetic ejection structure acting on the formed part, facilitates the demolding of the formed part, reduces the possibility of leaving a pressure mark on the formed part, and reduces the defective rate.
