Description
Technical field
The utility model relates to the cylinder diesel engine pile hammer for building engineering construction, relates in particular to the adpting flange of cylinder diesel engine pile hammer.
Background technology
In the building foundation engineering pile driving equipment, the advantage such as tubular diesel pile hammer is large with its impact force, high efficiency, reliability is strong, operating maintenance is convenient and being used widely.And along with the development of the large foundation engineerings such as offshore oil platform, deep water port harbour and bridge spanning the sea, need the larger cylinder diesel engine pile hammer of blow energy.
In cylinder diesel engine pile hammer when work, do not only depend on the explosive force piling of burning, and the powerful impact force that also produces during top piston impact lower piston is driven piles; And in this double piling, its upper piston, lower piston and the lower cylinder that is placed in outside the two-piston thereof are very crucial work done parts.The lower piston of cylinder diesel engine pile hammer is to be connected on the lower surface of lower cylinder by the adpting flange of pivot bush unit in its neck; All be lined with cushion pad on the upper and lower plane of this adpting flange.The effect of this adpting flange has: the one, and the guiding that lower piston moves up and down; The 2nd, it is spacing that lower piston moves up and down, and guarantees that lower piston must not throw off with lower cylinder; The 3rd, because lower plane is equipped with inside and outside cushion pad on the adpting flange, so adpting flange is the vitals that bears the descending impact of lower piston and the whole descending impact of pile hammer.
Owing to be subjected to the restriction of lower piston structure, cutting ferrule always adopts dissection type lap joint flange structure in the adpting flange of lower piston larynx neck at present, and two half flange that are the semicircle ring type interconnect by the bolt that is loaded on its flange place; In order to improve the guiding anti-wear performance of adpting flange, mostly also be inlaid with the flange grommet that is semi-loop at the inner hole wall of flange.The adpting flange of this dissection type shows many deficiencies in actual use: at first this adpting flange frequently bears huge impact forces, the connecting bolt that connects half flange is easy to occur loosening, even come off, not only have a strong impact on integral rigidity and the stressed uniformity of adpting flange, come off the security incidents such as cause damage of equipment from cylinder but also can cause lower piston; Moreover this half flange with flange connector will pass through at least casting, preliminary working, is connected, the multiple working procedure such as whole processing, and not only difficulty of processing is large, and production efficiency is low, and expends more metal material, and stock utilization is low; Secondly this structure has also increased the assembling maintenance difficulty of adpting flange.
The utility model content
For the existing above-mentioned deficiency of prior art, technical problem to be solved in the utility model provides the nested type adpting flange that a kind of integral rigidity is good, be convenient to installation and maintenance.
In order to solve the problems of the technologies described above, nested type adpting flange of the present utility model comprises embedded flange ring, and this embedded flange ring is by two relative semicircular ring combinations, described embedded flange ring is embedded in the endoporus of the flange collar, and this flange collar adopts whole circular ring structure; And embedded flange ring and the flange collar are bonded to each other with circular bead surface.
After adopting said structure, because the embedded flange ring of subdivision structure is nested in the integrally-built flange collar endoporus, two semicircle flange rings of embedded flange ring still can be easily from the both sides cutting ferrule of lower piston in the larynx neck position of lower piston, to realize the guiding of lower piston and spacing; And the integrally-built flange collar can provide enough firmly banding effects to embedded flange ring, even this just so that adpting flange bearing in the frequent enormous impact active force situation, integral rigidity and the integrality that still can keep the adpting flange long-term stability, avoided the generation of the security incidents such as slippage damage of lower piston and lower cylinder fully, adpting flange is more lasting reliable to the steering capability of lower piston, is conducive to the raising of pile hammer blow performance.Owing to adopt said structure, there is not any Bolt Connection between the circular ring type flange yet, removed flange connector structure of the prior art, make continuous flange more be convenient to make processing, save raw material, greatly improved the manufacturability of these parts.Simultaneously, this structure is more convenient for assembling, maintenance and the replacing of adpting flange.
Preferred embodiment of the present utility model, the hole wall of described flange collar endoporus is provided with shoulder, also is provided with shoulder on the outer ring surface of described embedded flange ring, and the circular bead surface of this flange collar and the circular bead surface of embedded flange ring mutually are close to and are closed.This shoulder structure has realized that the flange collar connects with the axial location of being connected between flange ring, and this positioning connection structure is simple and reliable.
Further embodiment of the present utility model is inlaid with the flange grommet at the inner ring surface of embedded flange ring, and this flange grommet is combined by two relative semicircular ring, the semicircular ring of the corresponding embedded flange ring of the semicircular ring of each flange grommet.Embedded with flange grommet in embedded flange ring not only is conducive to improve the slide-and-guide of adpting flange, and is conducive to prolong the application life of adpting flange.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model nested type adpting flange is described in further detail.
Fig. 1 is the front view of a kind of implementation structure of the utility model nested type adpting flange;
Fig. 2 is the top view of structure shown in Figure 1;
Fig. 3 is the front view of the another kind of implementation structure of the utility model nested type adpting flange.
