Large breaking hammer is one of the commonly used accessories of excavators. It is often necessary to break the operation in house demolition, mining, and urban construction planning. If the operation method of the breaking hammer is wrong, it will not only delay the progress of the project, but also easily cause the broken The hammer is damaged. Therefore, it is important to use the breaker scientifically and rationally. Let the editor briefly introduce the matters that need to be paid attention to in the use of the breaker. During operation, only by paying attention to these problems can it be changed For safe use of equipment.
1, vertical tap
Before the operation of the breaking hammer, place the chisel vertically on the broken object, and then open the hammer after confirming that the chisel is stable. In the crushing operation, it is also necessary to ensure that the chisel is perpendicular to the object to be struck at any time; If the hitting surface is skewed, the chisel may slip and deflect, which will damage the chisel and piston of the hammer.
2, Prohibition of empty play
When the large breaker is in operation, the chisel must be close to the object to be struck at any time. If the object to be struck has been broken, please stop knocking immediately. The empty strike will cause the chisel, flat pin, chisel seat, front cylinder Both body and bolt shank have serious damage.
3, can not be broken in water operation
The breaker is not a closed structure, and it cannot be soaked in water at ordinary times. It is very easy to damage the piston cylinder and the hydraulic oil circuit of the excavator. Therefore, try not to operate it in rainy days or in water; in special cases, except for the drill, Other locations cannot be submerged in water.
During the operation of the breaking hammer, a very large kinetic energy will be transmitted to the rock formation. If the rock formation is broken immediately, the kinetic energy will be released. If the rock formation has a high hardness standard and is still unbroken after several hits, it will be converted into a very large thermal kinetic energy, making the drill rod The temperature at the tip can reach more than 400 degrees Celsius, which will lead to decarburization and softening of the drill rod, resulting in coiling or even block falling on the surface. Therefore, if the large breaking hammer cannot be broken for a long time, find a way to change to other breaking methods.
