Cutting device for bridge construction

Abstract

The invention discloses a cutting device for bridge construction. The cutting device comprises a cutting motor and a cutting blade, wherein an output shaft of the cutting motor is connected with the cutting blade; the cutting device further comprises a base, a supporting rod, a connecting rod, a ball head assembly, a lifting assembly and a handheld assembly, one end of the supporting rod is connected with the upper end face of the base through a pin, the other end of the supporting rod is connected with one end of the connecting rod through the ball head assembly, and the other end of the connecting rod is fixedly connected with the cutting motor; the lifting assembly is arranged between the middle of the supporting rod and the base, and the middle of the supporting rod is connected with the upper end face of the base through the lifting assembly; and the side face of the connecting rod is connected with the handheld assembly. According to the cutting device, people can control the handheld assembly to enable the connecting rod to achieve multi-angle rotation, so that the cutting motor and the cutting blade which are fixedly connected to the end of the connecting rod can achieve multi-angle cutting construction operation, and convenience is brought to use of the cutting device.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a cutting device for bridge construction. Background technique [0002] In the construction of bridges, in order to increase the stability and strength of the bridge, it is often necessary to drill holes in the cement supporting the bridge and implant anchor rods for reinforcement, and finally repair operations at the drilled positions so as not to affect the outer surface of the bridge. To strengthen the stability of the repaired bridge surface, the repair hole is generally set in the shape of a square pyramid with a small inside and a large outside. side), and then use a percussion drill to drill out the concrete between the slope grooves to form a quadrangular pyramid-shaped repair hole. People can drill holes in the repair hole and implant anchor rods, and finally use concrete to fill the repair hole. , Repairing the large and small structure inside the hole can make the s...

Problems solved by technology

[0003] However, when cutting inclined grooves in repaired holes, the use of general hand-held cutters will make people too close to the construction surface, and the dust generated by cutting concrete will easily enter people's eyes and cause serious damage to eyes. Holding time consumes people's physical strength to a great extent; the patent No. CN201822100255.1 discloses a vertical cutting device for road and bridge construction. Although it solves the above problems, it can only make the cutting blades perform vertical construction. Surface cutting, cannot be operated when cutting constructions like beveled grooves, therefore, it is necessary to study a cutting device that saves physical strength to achieve multi-angle cutting operations
