A drill rod displacement trigger mechanism of a breaking hammer

Abstract

The invention discloses a drill rod displacement trigger mechanism of a breaker in the technical field of breaker hammers, which includes a drill rod, a drill sleeve is arranged at the top end of the drill rod, and a sleeve is arranged at the outer bottom end of the drill sleeve and is connected with the sleeve. Fixed connection, the outer side of the sleeve is threadedly connected with a collar, the outer side of the collar is provided with an occasional support rod, the bottom end of the support rod is provided with a connecting rod and is threadedly connected with the connecting rod, and the bottom end of the connecting rod is provided with a displacement Assembly, the displacement assembly includes an annular support plate, a block, a slide bar, an electric telescopic rod, a spring and a gray cloth, the annular support plate is arranged at the bottom end of the connecting rod and is fixedly connected with the connecting rod, and the block is set It is on the outer side of the ring support plate and fixedly connected with the ring support plate. When crushing through this structure, the slide bar first contacts with the working surface and drives the slide bar to move upwards, and then breaks through the work of the drill rod. The drill rod is in contact with the ground at the beginning of work, and there will be no empty strike. Able to protect the chisel.

Description

technical field [0001] The invention relates to the technical field of breaking hammers, in particular to a drill rod displacement trigger mechanism of a breaking hammer. Background technique [0002] At present, the breaker has various drive modes such as hydraulic drive, nitrogen drive, nitrogen and hydraulic drive, gravity drive, etc. Each drive mode is achieved by hitting the drill rod at high speed so that the drill rod has a large kinetic energy in an instant to achieve crushing. The effect of the object; when the chisel is hit, the huge kinetic energy is released by breaking the object; but when the chisel is not in contact with the object before work, the beating is still in progress, and the huge beating kinetic energy cannot be released. It will cause great damage to the drill rod, which will increase the operating cost of the equipment, and there will be a lot of dust during actual construction, which will pollute the environment; [0003] As disclosed in the Chi...
