Abstract

The utility model discloses a muting hydraulic breaking hammer which comprises an integral box shell, a connecting disc, a hammer core and a noise damping device. The upper end of the shell is open and a round hole is formed at the lower end of the shell and runs through the lower end of the shell. The upper end of the connecting disc is installed on a digger, a loader or a power station, and the lower end of the connecting disc is connected with the upper end of the integral box shell through a bolt. The upper part of the hammer core is disposed in the integral box shell and the lower end of the hammer core runs through the round hole of the integral box shell to extend to the outside. The noise damping device is arranged among the inner surface of the integral box shell, the connecting disc and the outer surface of the upper part of the hammer core. The upper part of the hammer core is tightly wrapped by the integral box shell and the noise damping device made of rubber plates; in this way, the noise produced when the hammer core works can be minimized through the integral box shell and the noise damping device, thereby maximumly reducing the noise diffused to the outside. Therefore, the muting hydraulic breaking hammer is unlikely to affect people's normal life and work.

Description

The mute type hydraulic breaking hammer

Technical field

The utility model relates to a kind of breaker, particularly relates to a kind of mute type hydraulic breaking hammer.

Background technology

Hydraulic breaking hammer is a kind ofly hydraulic pressure can be able to be converted into mechanical energy, thereby the external facility of acting are mainly used in work such as fragmentation, dismounting, excavation hard formation, are installed in usually on excavator, loader or the power station.Hydraulic breaking hammer at present commonly used mainly is made of the split type housing and the hammer core that are used to connect excavator, loader or power station, and its middle shell is made up of two clamping plates, and will hammer core top into shape by bolt and tightly be clipped in the middle.But, there is following point in the hydraulic breaking hammer of above-mentioned this prior art: because two clamping plates can only cover the part-structure of hammer core, thereby other position of hammer core will expose outside, and the hammer core is the working portion of hydraulic breaking hammer just, it can produce very big noise usually during work, therefore the noise by its generation will certainly outwards transmit, and especially when the work of the crowd is dense district, huge noise tends to influence people's normal life and work.In addition, minimum needs when assemble case and hammer core with 8 very thick king-bolts, need very big screw-down torque simultaneously, especially at the construction field (site), need basically to tighten with sledgehammer, this is because the vibration in hydraulic breaking hammer when work is very big, so if bolt is stubborn not tight, often might have an accident, the result not only can cause assembling inconvenience, and staff's labour intensity is big during assembling.

Summary of the invention

In order to address the above problem, the purpose of this utility model is to provide a kind of can reduce noise significantly, and mute type hydraulic breaking hammer easy to assembly.

In order to achieve the above object, the mute type hydraulic breaking hammer that provides of the utility model comprises whole box-type shell, terminal pad, hammer core and noise-decreasing device; The upper end of its middle shell is opening-like, and the lower end is run through and is formed with a circular hole; The upper end of terminal pad is installed on excavator, loader or the power station, and its lower end links to each other with the upper end of whole box-type shell by bolt; The top of hammer core is positioned at the inside of whole box-type shell, and the lower end is run through the circular hole on the whole box-type shell and extended to the outside; Noise-decreasing device then is arranged between the external surface on inner surface, terminal pad and hammer core top of whole box-type shell.

Described noise-decreasing device is the rubber-like rubber tile.

The mute type hydraulic breaking hammer that the utility model provides is to utilize whole box-type shell and tightly wrapped up by the top that the noise-decreasing device that rubber tile is made will be hammered core into shape, the noise that produces in the time of so just can making the work of hammer core by whole box-type shell and noise-decreasing device minimizes, thereby can reduce outside noise transmitted significantly, therefore can not influence people's normal life and work.In addition, because the top of hammer core can place the inside of whole box-type shell fully, therefore the bolt that is used for fixing terminal pad and whole box-type shell is more much smaller than prior art, so only need to finish with common wrench, so not only assemble very conveniently, and can alleviate staff's labour intensity significantly.

Description of drawings

The mute type hydraulic breaking hammer side direction structural representation that Fig. 2 provides for the utility model.

Fig. 3 be among Fig. 2 A-A to sectional view.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the mute type hydraulic breaking hammer that the utility model provides is elaborated.

As shown in Figure 1-Figure 3, the mute type hydraulic breaking hammer that provides of the utility model comprises whole box-type shell 1, terminal pad 2, hammer core 4 and noise-decreasing device 5; The upper end of its middle shell 1 is opening-like, and the lower end is run through and is formed with a circular hole 6; The upper end of terminal pad 2 is installed on excavator, loader or the power station, and its lower end links to each other with the upper end of whole box-type shell 1 by bolt 3; The top of hammer core 4 is positioned at the inside of whole box-type shell 1, and the lower end is run through the circular hole 6 on the whole box-type shell 1 and extended to the outside; Noise-decreasing device 5 then is arranged on inner surface, the terminal pad 2 of whole box-type shell 1 and hammers into shape between the external surface on core 4 tops.

Described noise-decreasing device 5 is the rubber-like rubber tile.The rubber tile that wherein is arranged on hammer core 4 end faces can limit the up and down of hammer core 4, is arranged on hammer core 4 tops rubber tile all around and then can limits the movable of hammer core 4 all around.In addition, because rubber tile has cushioning effect, the noise that produces in the time of therefore can absorbing 4 work of hammer core.

When mute type hydraulic breaking hammer that needs assemblings the utility model provides, at first needs being arranged on hammer core 4 tops rubber tile all around is placed on the respective inner surfaces of whole box-type shell 1, to hammer core 4 then into shape from the upper end open of whole box-type shell 1 its inside of packing into, on hammer core 4 end faces, install rubber tile more afterwards, utilize bolt 3 that whole assembling process can be finished in the upper end that terminal pad 2 is fixed on whole box-type shell 1 at last.
