Locking connection device and method for steel rope heads with tensile force

Abstract

The invention provides a locking connection device and method for a steel rope rope head with tension. The locking connection device consists of a pressing pump, a hydraulic cylinder, a pressure nut, an adjusting bolt, a guide block, a guide rod, a safety nut, an upper locking block, a lower It is composed of locking block and pre-tightening nut; both sides of the hydraulic cylinder with the pressing pump are provided with guide blocks connected by adjusting bolts, the cylinder rod of the hydraulic cylinder is connected to the upper locking block, the guide block, the upper locking block and the lower locking block Connected together by guide rods. Insert the two rope ends into the grooves of the upper locking block and the lower locking block, rotate the pre-tightening nut to make the lower locking block rise to fix the position of the two steel rope rope ends, and press the pressure pump to drive the hydraulic cylinder rod. The upper locking block presses the two steel rope ends into the slot, and locks the safety nut to the upper locking block. The invention can quickly perform the locking connection of the large steel rope head with tension, reduce labor intensity, shorten the steel rope connection time, improve the working efficiency of personnel and the production capacity of the unit, and avoid personal injury accidents.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to a locking connection device and method for a large steel rope end with tension. Background technique [0002] The combined unit of the cold rolling mill is a process of producing cold rolled steel coils, mainly pickling and rolling the hot rolled raw materials. The horizontal looper of the unit is driven by a steel rope to pull the trolley, and the other end of the steel rope is tensioned by a tensioning hydraulic cylinder. Since the stretching amount of the steel rope will increase with the extension of the stretching time during the production process, it is necessary to manually tighten the steel rope on a regular basis. The tensioning operation requires three people to fix the rope clamp together. However, the steel rope already has a lot of tension when it breaks away from the wedge, and an auxiliary steel rope is needed to fix it. Since there is no wedge to ...

Problems solved by technology

However, the steel rope already has a lot of tension when it breaks away from the wedge, and an auxiliary steel rope is needed to fix it. Since there is no wedge to fix it, an ordinary steel rope is used to fix the two steel rope ends. It takes a lot of time and manpower to fasten the rope clamp, and it needs to be tested by the movable hydraulic cylinder until the steel rope is fastened. There is a great security risk
