Embodiment
Describe the utility model in detail below in conjunction with the accompanying drawings.
Hammer ram as shown in Figure 1-2, including：Hammer body 1, hammer ear 2, hammer bottom 3, bolt hole 4, passage 5 and noise reduction lid 6.
Hammer body 1 is cylinder, and top surface is welded with hammer ear 2.Hammer the bottom surface that bottom 3 is arranged on hammer body 1, including formed by integrally casting shaping into shape
Top 7 and bottom 8, top 7 is the cross section cylinder equal with hammer body 1, and the cross section of bottom 8 is less than hammer body 1 and by upper
It is gradually reduced under, the bottom surface on top 7 has projection section relative to bottom 8.
The quantity of bolt hole 4 is six, extends vertically through hammer body 1 and top 7, the bottom surface on top 7 offers six around bottom 8
The bolt indentation 11 communicated with bolt hole 4, hammer body 1 and top 7 are removably tight by the bolt 12 of six major diameters, high intensity
Close connection, as shown in Fig. 2 bolt 12 inserts bolt hole 4 from bottom, bolt head is fixed in bolt indentation 11, the top of bolt 12
End is screwed by nut.
Although employing multiple bolts 12 between hammer body 1 and hammer bottom 3 and being attached fixation, due to hammer ram heavier-weight,
The fixation of bolt 12 is only leaned on, many inconvenience can be caused in disassembly and installation.Therefore, offered at the bottom centre of hammer body 1
The neck 9 of inverted L shape, the grab 10 of inverted L shape is welded with the end face center on top 7, as illustrated in figures 4-5, grab 10 is arranged on card
It is in groove 9 and cooperating therewith, hammer body 1 and hammer bottom 3 are further reinforced.Neck 9 includes vertical channel 17 and horizontal channel
18, grab 10 includes vertical component 19 and horizontal component 20, and the Cross section Design of vertical channel 17 is into making horizontal component 20 just logical
Cross, horizontal component 20 closely agrees with horizontal channel 18, and vertical channel 17 is highly identical with vertical component 19 so that Gu timing card
Hook 10 is fully mounted in neck 9, is not interfered with hammer body 1 and is hammered being brought into close contact for bottom 3 into shape.
The quantity of passage 5 is four, extends vertically through hammer body 1 and hammer bottom 3, and four passages 5 are uniformly distributed around hammer ear 2.
Noise reduction lid 6 is arranged on the top of passage 5, torus 13 and bloop 14 is specifically included, as shown in figure 3, the end of torus 13
It is fixed on by rotating shaft 15 by passage 5, torus 13 can surround rotating shaft 15 and rotate horizontally to covering passage 5, bloop
14 are made up of lightweight quieter material, are fixed on inline in torus 13, and cross bore 16 is offered at the center of bloop 14.
When hammer ram works, torus 13 is rotated to the top of passage 5, bloop 14 and is not only able to enter the noise at passage 5
Row barrier, moreover it is possible to be effectively isolated the fragment of splashing, reduce the speed of air-flow, while cross bore 16 can effectively discharge gas.Ram
It is rotatable to remove torus 13 when hammer is stopped, the dust adhered in passage 5 is cleared up.
Hammer body 1 is connected by bolt 12 with hammer bottom 3 and detachably, both directly can be used for gravelly soil, sand using hammer body 1
The reinforcing of soil, the hammer bottom 3 of different model can also be used to be used for different soil property situations.Herein, hammer bottom 3 devises A, B, C tri-
Type, the top 7 of three types is identical, is cylindrical structure, diameter is consistent with hammer body 1, and bottom 8 is different.
As shown in fig. 6, A types body floor is plane, side is hyperboloid；Type B body floor is plane, and side is circular conical surface, in
Bore truncated cone-shaped；C-type body floor is arc surface.
When soil property is silt or cohesive soil, if not using hammer bottom 3, rams influence and be difficult to transmit to depths, and use A types
When hammering bottom into shape, increase because tamping pit center pressure is relative, do not increase ram energy level in the case of ram influence depth and deepen significantly,
Therefore A set hammers bottom is preferably used.When effective reinforcement depth requires higher, tamping pit pitch requirements can not be too small, if not using hammer bottom
3, it may appear that native phenomenon of collapsing, and also intensity differs larger with tamping point between rammer, and during use Type B hammer bottom, tamping pit side wall when ramming
Can be closely knit by the extruding of Type B hammer bottom side, native phenomenon of collapsing is reduced, and rams effect also relatively evenly, therefore preferably use Type B
Hammer bottom into shape.When soil property is collapsible loess or larger water content, if not using hammer bottom 3, suction hammer phenomenon is serious, and uses c-type to hammer into shape
During bottom, frictional force greatly reduces, and inhales hammer, viscous hammer phenomenon can also reduce, therefore preferably use c-type to hammer bottom into shape.In addition, in Practical Project only
A hammer body and several hammer bottoms, which need to be carried, can meet the needs of different engineerings, compared to the strong rammer hammer for being equipped with multiple different energy levels
For, save fund and improve engineering efficiency.
It should be noted that cited such as " on ", " under ", the use of "left", "right", "front", "rear" in utility model
Language, be merely convenient to narration understand, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or
Adjustment, in the case where changing technology contents without essence, when being also considered as the enforceable category of the utility model.
It the above is only preferred embodiment of the present utility model, the scope of protection of the utility model is not limited merely to above-mentioned
Embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should be pointed out that pair
For those skilled in the art, some improvements and modifications under the premise of the utility model principle is not departed from,
It should be regarded as the scope of protection of the utility model.
