Abstract
The utility model discloses a cylinder hammer of an improved guide rod type diesel pile hammer, which is characterized in that a removable cylinder sleeve is nested in the cylinder hammer body. When the worn clearance of the cylinder sleeve becomes too large to work, repair for the hammer can be completed via replacing the cylinder sleeve. The utility model has the advantages of convenient repair, low repair cost, and high construction efficiency.
Description
The utility model relates to the building operations guide rod type diesel pile hammer, especially the improvement of guide rod type diesel pile hammer cylinder hammer.
In building operations especially Pile Foundation construction, pile driver is one of important construction machinery, and wherein guide rod type diesel pile hammer is widely used with the advantage of piling efficient height, good reliability.In guide rod type diesel pile hammer when work,, the cylinder hammer freely falls by the deadweight effect, behind the cylinder borehole jack and piston of cylinder hammer, wrap between piston and cylinder-bore air by compression, temperature raises.When being compressed to a certain degree, diesel oil is vaporific and sprays in the cylinder-bore, mix with high-temperature gas, combustion explosion, the gases at high pressure that produce make cylinder hammer and piston do the rightabout motion, and the power that acts on the piston is sunk stake, the power that acts on the cylinder-bore moves upward the cylinder hammer, enters periodic duty next time.At present, the cylinder of guide rod type diesel pile hammer hammer all adopts overall structure and since cylinder hammer cylinder-bore inwall repeatedly with the direct contact friction of piston, the cylinder-bore inwall is worn gradually, and the gap between increasing and the piston, make the piling decrease in efficiency, finally cause and to work, must change whole cylinder hammer, not only caused serious waste, increase construction cost, and change trouble, prolong construction period.
The purpose of this utility model is to provide a kind of energy reusable cylinder hammer, and it not only makes the wearing clearance of cylinder-bore repair, and maintenance cost is low, and repairs simple and convenient.
In order to achieve the above object, technical solution of the present utility model is: the removable cylinder sleeve of setting-in on existing cylinder hammer body.Eliminate the wearing clearance of cylinder-bore by changing cylinder sleeve, reach cylinder and hammer reusable purpose into shape.
Because above-mentioned technical solution has been taked the structure of setting-in cylinder sleeve in the cylinder hammer, the cylinder sleeve of cylinder hammer body and Qi Nei is formed the cylinder hammer of this programme.During work, piston only directly contacts with cylinder sleeve, and do not contact with its cylinder hammer body, when the cylinder-bore gap becomes big, only need to change cylinder sleeve and can eliminate wearing clearance, the cylinder hammer body is still reusable, thereby greatly reduce use cost, convenient for maintaining, in addition, because cylinder sleeve is simple and reasonable, make repair convenient and swift again.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structure chart of the utility model Nesting cylinder hammer first embodiment;
Fig. 2 is the structure chart of the utility model Nesting cylinder hammer second embodiment;
Fig. 3 is the structure chart of the utility model Nesting cylinder hammer the 3rd embodiment;
In Nesting cylinder hammer shown in Figure 1, the cylinder hammer is made up of cylinder hammer body 1 and cylinder sleeve 2.Cylinder sleeve 2 adopts book wall tubular structure, and cylinder sleeve 2 embeds in the cylinder hammer body 1 by being press-fitted, and when cylinder sleeve 2 internal diameters can not use because of wearing and tearing, only need more renew cylinder sleeve, and 1 of cylinder hammer body still continues to use.This structure not only Replacement and Repair is convenient, and rehabilitation cost is very cheap.
In the Nesting cylinder hammer shown in Figure 2, the cylinder hammer body adopts split type structure, is formed by connecting by upper cylinder half hammer body 1 and following cylinder hammer body 3.Cylinder sleeve 2 adopts tubular structure; Cylinder sleeve 2 clamps between the upper and lower cylinder hammer body that connects firmly, and this structure helps the replacing of cylinder sleeve 2.
In the Nesting cylinder hammer shown in Figure 3, cylinder sleeve 2 is cast as one with cylinder hammer body bottom, and cylinder sleeve 2 tops embed in the cylinder hammer body 1, and connects firmly with cylinder hammer body 1 and constitute the cylinder hammer.Certainly cylinder sleeve 2 also can be cast as one with cylinder hammer body top.The structure that the part of this cylinder sleeve 2 and cylinder hammer body is cast as one is more conducive to the quick replacing of cylinder sleeve.
The combination connecting mode of cylinder sleeve and cylinder hammer body is not limited to above-mentioned several form, and other adopts the structure of replaceable cylinder sleeve, also belongs to protection domain of the present utility model.
Claims (4)
