Equipment for shearing retaining mounting groove in flat steel of steel grating

Abstract

The utility model relates to equipment for shearing a retaining mounting groove on flat steel of a steel grating. The utility model aims to solve the problem that the retaining mounting groove is sheared on the flat steel of the steel grating, however, no special equipment for shearing the retaining mounting groove on the flat steel of the steel grating exists at present. According to the technical scheme, a hydraulic cylinder is connected with a fixed cutter rest through four screws, a piston rod of the hydraulic cylinder drives movable cutters on the two sides, the cutting edges of the movable cutters are herringbone inclined blades, fixed cutters are arranged below the movable cutters to form a shearing device, and flat steel placing and guiding grooves of the steel grating are formed between the movable cutters and the fixed cutters. The method is suitable for machining the mounting piece of the steel grating.

Description

TECHNICAL FIELD

[0001] The utility model relates to the processing equipment of steel grating mounting clamp, specifically is a kind of equipment of shearing stop-retreating installation groove on steel grating flat steel. BACKGROUND

[0002] At present, when steel grating is installed by mounting clamp, mounting clamp is composed of M-shaped upper clamp and lever-type lower clamp, and upper clamp and lower clamp are fastened by bolt connection. In the use of steel grating, due to vibration and elastic deformation, upper clamp slides along the direction of flat steel, thereby causing mounting clamp to loosen, which leads to mounting clamp to fall off. The reason for this problem is that the existing upper and lower mounting clamps do not have reliable stop-retreating design, which leads to loosening and falling off. In addition, after the installation of upper and lower clamps, the upper clamp protrudes above the plane of steel grating by about 3mm in thickness, which causes the risk of tripping when people walk, and is not safe enough. Shearing stop-retreating installation groove on steel grating flat steel can effectively solve the above problems, but there is currently no equipment specially used for shearing stop-retreating installation groove on steel grating flat steel. SUMMARY

[0003] The purpose of the utility model is to provide a kind of equipment of shearing stop-retreating installation groove on steel grating flat steel to solve the background technology: shearing stop-retreating installation groove on steel grating flat steel can effectively solve the above problems, but there is currently no equipment specially used for shearing stop-retreating installation groove on steel grating flat steel. The technical scheme adopted to solve the technical problem is: a kind of equipment of shearing stop-retreating installation groove on steel grating flat steel, characterized by: hydraulic cylinder is connected with fixed knife holder through four screw rods, the piston rod of hydraulic cylinder drives the dynamic knife on both sides, the cutting edge of dynamic knife is "person" type inclined blade, and the fixed knife on the fixed knife holder below dynamic knife forms a shearing device, and the flat steel of steel grating is placed in the guide groove between dynamic knife and fixed knife. A handle is arranged on the fixed knife holder. Hydraulic cylinder is supplied with oil by standard portable pump.

[0004] The utility model has the beneficial effects compared with the background technology: due to the above technical scheme, the equipment is used to shear stop-retreating installation groove on steel grating, which solves the problems in the background technology: the existing upper and lower mounting clamps do not have reliable stop-retreating design, which leads to loosening and falling off. In addition, after the installation of upper and lower clamps, the upper clamp protrudes above the plane of steel grating by about 3mm in thickness, which causes the risk of tripping when people walk, and is not safe enough. Thus, the sliding of mounting clamp along the direction of flat steel is avoided, and the firmness of mounting clamp and the obstacle-free protrusion of steel grating on horizontal plane are ensured.
