Multiple-angle rotary brick cutter

Abstract

The invention discloses a multiple-angle rotary brick cutter which comprises a rack and an arc-shaped plate. A small rotary shaft is respectively arranged at two ends of the arc-shaped plate and is connected with the rack and drives the arc-shaped plate to rotate. A cutting device is arranged above the arc-shaped plate and comprises a motor and a rotary shaft with two ends connected to the rack, the rotary shaft vertically penetrates through a rotating arm, a cutting piece is arranged at the lower end of the rotating arm, and a drive shaft of the cutting piece is connected with the driving end of the motor through a belt. The axis of the rotary shaft and the axis of the arc-shaped plate are located on the same straight line, and the rotating arm rotates around the rotary shaft. The multiple-angle rotary brick cutter is supported by the arc-shaped plate and can be used for batch processing of wholly-semicircular refractory bricks for building of arched brickworks, a cutting angle can be changed by turning the arc-shaped plate, and wholly non-semicircular refractory bricks can be processed to meet the building requirement of brickworks. The stability of the arc-shaped plate in the cutting process is ensured by adopting a locking device, and cutting accuracy is improved.

Description

technical field [0001] The invention relates to the field of industrial furnace construction, in particular to a multi-angle rotary brick cutter. Background technique [0002] In the masonry construction of industrial kiln masonry, some arched masonry is often encountered. For example, in the hot air surrounding pipe of the blast furnace system, a layer of refractory masonry needs to be built on the inner wall of the surrounding pipe. If non-standard refractory bricks are used, it is necessary to cut the refractory bricks processed in batches to build arched masonry that meets the requirements. At present, the commonly used method is: first, the workers pre-place the refractory bricks inside the surrounding pipe, then draw lines on the refractory bricks according to the size of the masonry, and then process each refractory brick in turn according to the marking lines. The traditional brick cutting machine can only cut one refractory brick at a time, and most of them can onl...

AI Technical Summary

Problems solved by technology

The traditional brick cutting machine can only cut one refractory brick at a time, and most of them can only achieve vertical cutting, which has low precision and low efficiency when cutting inclined surfaces; due to the structure of some industrial furnaces, such as the ring shape of the surrounding tube of a blast furnace, there are many bends Turn, and the size and structure of the inner and outer rings of the surrounding pipe are different. When the refractory masonry is constructed inside the surrounding pipe, there are masonry units of different shapes, such as semi-circular and non-semi-circular, which requires processing the whole Refractory bricks in different shapes and sizes
