Breaking hammer with novel vibration reduction principle

Abstract

The invention discloses a breaking hammer with the novel vibration reduction principle. The breaking hammer comprises a rectangular frame platform, a first mass block and a second mass block; the eccentric mass of first eccentric blocks is larger than that of second eccentric blocks, the eccentric distances of the first eccentric blocks and the eccentric distances of the second eccentric blocks are the same, and the phase angle difference between the first eccentric blocks and the second eccentric blocks is 180 degrees; the first mass block is placed on the upper surface of an upper platform,the second mass block is located above the upper platform, the second mass block is connected with the four corresponding second eccentric blocks through second cranks, and the first mass block is connected with the connecting rods between the opposite first eccentric blocks in two eccentric sets through two first cranks; and the second mass block is provided with a through hole for the first massblock to pass through. According to the breaking hammer with the novel vibration reduction principle, loss of structures such as an air spring is reduced, and benefits are increased; a dustproof cover only plays a role in dust prevention, and structural damage caused by the fact that transmitted energy needs to be absorbed when the dustproof cover is connected with the spring is avoided; the working state depends on whether external pressure acts on a crushing hammerhead or not, empty beating and energy loss are avoided, and noise is reduced.

Description

technical field [0001] The invention relates to a demolition device, in particular to a breaking hammer with a novel vibration reduction principle. Background technique [0002] The breaking hammer is a common tool in the process of building demolition and mining. At present, the vibrating breaking hammer, which uses several eccentric blocks to rotate in opposite directions to promote the superposition of vertical force and offset the horizontal force, is favored in the demolition industry due to its advantages of high efficiency and low noise. However, (1) Due to the large vertical force of this type of breaker, the air springs, metal springs and composite springs currently applied to this type of breaker always have problems such as serious spring consumption or structural damage caused by incomplete vibration reduction. , the reason is that no matter what kind of spring is used, the installation form of the spring and the vibration reduction principle are basically the sa...

[0002] The breaking hammer is a common tool in the process of building demolition and mining. At present, the vibrating breaking hammer, which uses several eccentric blocks to rotate in opposite directions to promote the superposition of vertical force and offset the horizontal force, is favored in the demolition industry due to its advantages of high efficiency and low noise. However, (1) Due to the large vertical force of this type of breaker, the air springs, metal springs and composite springs currently applied to this type of breaker always have problems such as serious spring consumption or structural damage caused by incomplete vibration reduction. , the reason is that no matter what kind of spring is used, the installation form of the spring and the vibration reduction principle are basically the same, that is, the energy is absorbed by the deformation of the spring between the breaker box and the vibration structure, which causes the above problems; ( 2) Since this type of breaker does not have the function of automatically adjusting the flow rate, the same exciting force is always used when breaking different objects, resulting in waste of energy, high noise and prone to damage to the machine.
