The utility model discloses a quenching furnace for bearing steel grit production, which comprises a support, a furnace body fixed on the top of the support, a moving plate slidably connected on the top of the support, a tray hinged on the outer wall of the top of the moving plate, stop levers fixed on the outer walls of two sides of the tray, an oil cylinder hinged inside the support, and a bracket fixed on an output shaft of the oil cylinder. A matching groove matched with the stop lever is formed in the bracket, an inclined face is arranged on the outer wall of the top of the bracket, an air support is hinged between the oil cylinder and the support, and a quenching liquid pool is arranged on one side of the support. Through the arrangement of the oil cylinder, the tray and the movable plate, the tray on the movable plate is driven by the oil cylinder to incline, so that steel grit on the tray can be quickly poured into a quenching liquid pool, the effect that the steel grit can enter quenching liquid in time after being discharged from a furnace is further ensured, and meanwhile, manpower needed for manually pouring the steel grit into the quenching liquid is also saved.

The invention discloses a cage trolley carrying robot and a carrying method. The cage trolley carrying robot comprises a first chassis and a second chassis which are connected through a hinge shaft, and a chassis body capable of self-adapting to the terrain is formed; the scissor-fork assembly stretches across the double chassis, one end of the scissor-fork assembly is hinged to the first chassis, and the other end of the scissor-fork assembly is hinged to the second chassis; the moving assembly comprises a driving wheel with a damping seat and a universal wheel; a two-dimensional code camera is integrated on the scissors fork arm, and the two-dimensional code camera and the SLAM laser part on the chassis form a hybrid navigation system; through the design of the hinged chassis and the cross-chassis shear fork mechanism, the ultralow initial height of the robot is achieved, and the robot can enter low spaces such as the bottom layer of a goods shelf; the road holding force of the driving wheel is enhanced and the trafficability and the stability of the complex ground are improved by utilizing the coupling of the mechanical characteristics of the hinge structure and the shear fork mechanism; the hybrid navigation mode can be flexibly switched according to scenes, global autonomy and node accuracy are integrated, and the automation level, environmental adaptability and operation efficiency of cage trolley carrying are improved.

The invention relates to an underwater square multi-angle mounting lifting appliance and a mounting method thereof, and belongs to the technical field of lifting appliances. The underwater square block multi-angle installation lifting appliance comprises a lifting frame, a lifting hook, a measurement and control unit and an adjusting unit, during square block underwater installation, lifting equipment is connected with a lifting lug of the lifting frame and moves to the square block, and the lifting hook extends into a lifting hole of the square block to lift the square block; after the square block is hoisted, the real-time position of the hanging bracket is monitored through the measurement and control unit, and the real-time position of the square block is obtained according to the real-time position of the hanging bracket; the square block is moved to a to-be-installed position through hoisting equipment, the posture of the square block is adjusted through an adjusting oil cylinder till the installation requirement is met, and the square block is lowered by the hoisting equipment for installation; and the square block is unhooked after being mounted. According to the underwater square multi-angle mounting lifting appliance and the mounting method thereof, the positioning monitoring function and the posture adjusting function are organically combined, so that posture correction of the square can be completed in one lifting process, the operation steps of underwater mounting are simplified, and the construction efficiency and the mounting precision are improved.

The invention discloses a steel support anti-falling safety mechanism and a construction method thereof.The steel support anti-falling safety mechanism comprises two sets of hooking components, each hooking component comprises a fixing plate, a supporting plate and a connecting support, the supporting plates are perpendicularly arranged on the fixing plates, the connecting supports are used for connecting the fixing plates and the supporting plates, and the supporting plates are arranged on the fixing plates; a key-shaped hole is formed in the fixing plate piece, and a clamping piece is arranged on the fixing plate piece. According to the hanging component, the hanging component is tightly clamped with the enclosing purlin through the clamping groove and is further stabilized by being matched with the clamp, accidental falling of the steel support caused by loose connection is effectively prevented, the steel strand inhaul cable and the anchorage device of the hanging component are combined, reliable lifting and limiting effects are provided for the steel support from the lower portion, the safety of a construction site is greatly improved, and the safety of the construction site is improved. And casualties and engineering accident risks caused by falling of the steel support are reduced.
