Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As first aspect of the present utility model, provide a kind of hammer ram.As shown in Figures 2 to 4, hammer ram comprises body 10 and noise elimination part 20, and body 10 has the steam vent 11 of the through setting of short transverse along body 10; Noise elimination part 20 is arranged on body 10, and noise elimination part 20 is positioned at the position at steam vent 11 place to eliminate the noise of the upper end exhaust ports of steam vent 11.Owing to being provided with noise elimination part 20, thus use in the process of hammer ram, effectively can eliminate because local air breaks the high-decibel noise produced, thus reduce the operating noise of hammer ram.Arrange because noise elimination part 20 is corresponding with steam vent 11, thus noise elimination part 20 can also to the blast sputtered in steam vent 11 and the effect playing interception of mincing, the movement velocity reducing blast and mince, thus avoid mincing through quick splashing of steam vent 11 and going out to wound staff, eliminate potential safety hazard.Meanwhile, the hammer ram in the utility model has that structure is simple, the feature of low cost of manufacture.
Preferably, noise elimination part 20 is fixedly connected with body 10.Preferably, noise elimination part 20 is welded with body 10, is riveted, bolt is connected.
Certainly, the hammer ram in the utility model can also pass through casting.
Noise elimination part 20 in the utility model is arranged on the upper end surface of body 10 and is positioned at the upper end exhaust ports of steam vent 11.Be arranged on the upper end surface of body 10 due to noise elimination part 20 and be positioned at the upper end exhaust ports of steam vent 11, the blast of thus discharging via steam vent 11 has the little feature of noise after noise elimination part 20 noise reduction process.
As shown in Figure 2 and Figure 4, noise elimination part 20 comprises hush pipe, and the openend of hush pipe is communicated with the upper end of steam vent 11, the barrel of hush pipe has multiple air vent 21.Due to the barrel of hush pipe having air vent 21, thus can ensure that the gas in steam vent 11 can be discharged by air vent 21 smoothly, avoid the bottom of body 10 to form low-pressure area.Meanwhile, the barrel of hush pipe also plays the effect of interception to the blast splashed through steam vent 11 with mincing, and avoids blast or mince threatening the personal safety of staff.
Preferably, the barrel of hush pipe comprises circumferential side wall 23 and the diapire 22 relative with openend, and air vent 21 is positioned in diapire 22 and/or circumferential side wall 23.
In preferred embodiment as shown in Figure 2 and Figure 4, all air vents 21 are all positioned in circumferential side wall 23, multiple air vent 21 forms air vent group, the circumference of the circumferentially sidewall 23 of the air vent 21 in air vent group is spaced setting, air vent group is multiple, and multiple air vent group is spaced setting along the diapire 22 of hush pipe to the direction of openend.Because all air vents 21 are all positioned in circumferential side wall 23, the diapire 22 of the blast thus splashed in steam vent 11 and the upwards impact sound reduction cylinder of mincing is able to reduction of speed, then gas is discharged via air vent 21, and mince and fall after rise to ground, thus play noise reduction, noise reduction, avoid mincing and splash and the effect that goes out, eliminate safe hidden trouble.Due to the arrangement mode rule of air vent 21, thus to make in hush pipe impact force size everywhere even, ensure that the noise reduction of noise elimination part 20.
Preferably, the circumference of the circumferentially sidewall 23 of the air vent 21 in air vent group equally spaced arranges.Because air vent 21 equally spaced arranges, thus to make in hush pipe impact force size everywhere even, ensure that the noise reduction of noise elimination part 20.
Preferably, multiple air vent group equally spaced arranges along the diapire 22 of hush pipe to the direction of openend.Because multiple air vent group equally spaced arranges, thus to make in hush pipe impact force size everywhere even, ensure that the noise reduction of noise elimination part 20.
In a not shown preferred embodiment, noise elimination part 20 is arranged in steam vent 11.Because noise elimination part 20 is arranged in steam vent 11, thus avoid the space outerpace taking hammer ram, avoid the impact that extraneous shock may cause noise elimination part 20, thus ensure that the dependability of hammer ram.
Preferably, noise elimination part 20 comprises bloop, and the circumferential edge of bloop is connected with the hole wall of steam vent 11, and bloop has multiple air vent 21, and multiple air vent 21 is arranged at intervals.Owing to being provided with air vent 21, thus can ensureing that the gas in steam vent 11 can be discharged by air vent 21 smoothly, avoid the bottom of body 10 to form low-pressure area.Because the circumferential edge of bloop is connected with the hole wall of steam vent 11, thus bloop is cross-section in steam vent 11, thus plays the effect of interception to the blast in steam vent 11 with mincing, and effectively reduces noise decibel, and splashing fast of avoiding mincing, and then improve the safety in utilization of hammer ram.
Steam vent 11 in the utility model is multiple, and multiple steam vent 11 is arranged at intervals, and noise elimination part 20 is at least one, and noise elimination part 20 is corresponding with at least one steam vent 11 to be arranged.
Preferably, the number of steam vent 11 is 3,4 or 5.Certainly, the number of steam vent 11 can also more than 5.
In preferred embodiment as shown in Figure 2 and Figure 4, noise elimination part 20 is multiple, and multiple noise elimination part 20 is arranged with multiple steam vent 11 one_to_one corresponding.Because each steam vent 11 is all independent of there being a noise elimination part 20, thus ensure that the noise reduction reliability of hammer ram, improve the dependability of hammer ram.
In preferred embodiment as shown in Figure 3 and Figure 4, the lower surface of body 10 has accommodation recess 12, holds recess 12 and is communicated with the lower end of steam vent 11.Lower surface due to body 10 has accommodation recess 12, thus when hammer ram lands, the lower surface place of body 10 holds the first kiss the earth of ring part branch around recess 12, now this annular section can intercept the injection of blast and shock wave, effectively prevent ground to mince splashing, improve the safety of hammer ram.But, also have part blast, shock wave, mince along steam vent 11 splash from bottom to top, now, noise elimination part 20 is understood this part blast, shock wave, is minced and play the effect of noise reduction, obstruction, noise elimination part 20 has Low Medium Frequency broadband acoustic attenuation performance, and when air-flow is through air vent 21, the frequency spectrum of jet noise will shift to high frequency or hyperfrequency, audible sound composition in frequency spectrum is obviously reduced, thus the interference reduced people and injury.Also blocking minces simultaneously splashes out.
Preferably, body 10 is cylindrical.
Hammer ram in the utility model can also be chip hammer ram.Namely body 10 has one by one that independently hammer leaf is stacked forms.
Hammer ram in the utility model also comprises hook portion 30, and hook portion 30 is connected with body 10.Preferably, hook portion 30 is positioned at the center position of the upper surface of body 10.
As second aspect of the present utility model, provide a kind of dynamic compaction machinery.Dynamic compaction machinery comprises hammer ram, and hammer ram is above-mentioned hammer ram.Hammer ram in the utility model has the advantages that safety is good, noise is little, thus improves the dependability of dynamic compaction machinery.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
