The invention discloses a steel structure drilling machine facilitated to disassembling and assembling a drill bit. The steel structure drilling machine comprises a base. A supporting column is fixedly connected to the right side of the top of the base, a top plate is fixedly connected to the top of the supporting column, an air cylinder is fixedly connected to the left side of the top of the topplate, the bottom of the air cylinder penetrates through the top plate and extends to the exterior of the top plate to be fixedly connected with a rotating motor, and a rotating shaft is fixedly connected to an output shaft of the rotating motor. According to the steel structure drilling machine facilitated to disassembling and assembling the drill bit, through mutual cooperation of clamping grooves, fixing shafts, supporting plates, clamping blocks, supporting springs, semicircle rings, first grooves, second grooves, first pulleys, bearing seats, first rotating shafts, driven bevel gears, rolling barrels, second rotating shafts, driving bevel gears, first handles, limiting holes, threaded grooves, threaded rods, second handles, and steel wire ropes, the action of facilitating to disassembling and assembling the drill bit is played, the disassembly and assembly process is simple, the time and labor are saved, the labor intensity of users is relieved, the drilling efficiency of the drilling machine is improved, and great convenience is brought to the users.

The invention discloses an emergency new energy vehicle charging pile, which includes a base, the top of the base is hinged to the bottom side of the charging pile body through a first hinged shaft, and the top of the base is tightly connected to the charging pile through a second hinged shaft. one end of the rod. The present invention uses a base, a port, a first fixed shaft, a moving wheel, a support column, a support plate, a side plate, a second fixed shaft, a fixed rod, a support spring, a block, a rolling bearing, a threaded rod, a threaded sleeve, a push rod, The support block, positive and negative motors, positive and negative shafts, driving gear and driven gear cooperate with each other to make the charging pile stable, and can be connected through the first bevel gear, the first transmission rod, the adjustment handle, the second umbrella The cooperation of the gear, the second transmission rod and the adjustment rod solves the problem that the components in the charging pile are easy to loosen and slip off when working on a steep slope, thereby improving the safety of the charging pile.

The invention discloses a self-warning anti-collision ammeter, which belongs to the technical field of electric meters. The invention can play the role of anti-collision by adding anti-collision strips around it. Elastic cushioning effect, and concentrate the impact force and transfer it to the force-collecting column, and then squeeze the energy-absorbing bag to achieve secondary buffering, which can effectively offset the external impact force, and is not easy to cause vibration to the ammeter body itself. The self-heating phenomenon is triggered during the extrusion process of the force-collecting column, and the heat is transferred to the thermal separation rod to promote its separation action, and then rely on the magnetic repulsion of the static magnetic ring on the early-warning film to force it to expand outward for early warning. It prompts the impact part, and at the same time, the expanded early warning film can increase the buffer barrier when facing the same impact, thereby improving the anti-impact ability of the ammeter.

The invention discloses a lifting conveying device for a glass production assembly line. The lifting conveying device comprises a rack, a conveying mechanism and a lifting mechanism. A base is mounted at the upper end of the rack, and the lifting mechanism comprises a lifting arm, a rotating disc, a telescopic arm set and a lifting device; the lifting arm and a telescopic oil cylinder are connected to the base, and the suspension arm is connected to the upper end of the telescopic oil cylinder; the rotating disc is connected to the upper end of the suspension arm, and the telescopic arm set is fixedly connected to the rotating disc and comprises telescopic arms; and the lifting device is connected to the telescopic arms and comprises a lifting motor, a lifting connecting rod, a hydraulic oil cylinder and a hydraulic suction cup. The lifting mechanism and the conveying mechanism are introduced, glass workpieces can be grabbed through the lifting mechanism and can be arranged in the rack through the rotation function of the rotating disc, and therefore the glass workpieces can be automatically lifted; and after lifting is completed, the glass workpieces are conveyed to the designated position through the conveying mechanism, and the glass workpieces can be automatically conveyed.
