Abstract
The utility model relates to a pile clamp used for pile hitting and pulling equipment such as a vibration pile hammer or an impact pile hammer and the like. The pile clamp comprises an oil cylinder body, a piston with a sealing piece, a guide sleeve, a piston rod and a clamp seat, wherein the clamp seat is a cylindrical piece with an opening at the lower part, an installation hole is arranged at one side of the clamp seat, the oil cylinder body is arranged in the installation hole by the guide sleeve, the piston is arranged in the oil cylinder body and is connected with the piston rod, the piston rod extends out from the interior of the guide sleeve and consists of a front-section rod and a rear-section rod, the front-section rod is connected with the rear-section rod by a connector, and a gap exists at the connecting part between the front-section rod and the rear-section rod. The pile clamp has the advantages that the structure is reasonable, the abrasion of a sealing piece can be reduced remarkably, and the service life of an oil cylinder can be prolonged.
Description
Technical field
The utility model relates to a kind of pile holder tool that vibrohammer or impact pile monkey etc. are beaten pile pulling equipment that is used for.
Background technology
The structure of the pile holder tool oil cylinder that present domestic pile monkey uses is with common oil cylinder, and piston rod is a monolithic.The major defect of such pattern is that the vertical force when playing pile pulling acts directly on the piston rod, and what piston rod was frequent vibrates because of stressed, and the sealing part abrasion of oil cylinder is very fast, and phenomenons such as leakage of oil just can appear in oil cylinder behind the sealing part abrasion, reduce the application life of oil cylinder; In addition, frequent vibration also can the time cylinder body, fairlead, piston rod be prone to pulled, thereby influenced the operate as normal of pile monkey.
Summary of the invention
The utility model provides a kind of rational in infrastructure in order to overcome above-mentioned defective, can significantly reduce sealing part abrasion, prolongs the pile holder tool of the pile pulling equipment of beating in oil cylinder life-span.
The technical scheme that the utility model adopts is: a kind of pile holder tool of beating pile pulling equipment, comprise piston, fairlead, piston rod and the clamping fixture seat of cylinder body, band seal, and described clamping fixture seat is the columnar member of bottom band opening; Side at clamping fixture seat is provided with installing hole; Fairlead is installed in the installing hole, and cylinder body is connected and is installed in the outside of installing hole with fairlead, and piston is arranged in the cylinder body; Piston is connected with piston rod; Piston rod stretches out from fairlead inside, and described piston rod is made up of leading portion bar and back segment bar, and the leading portion bar is connected with the back segment bar through connector; Seal is arranged between back segment bar and the fairlead, and the junction of leading portion bar and back segment bar is provided with gap
.
Described leading portion rod rear end is provided with groove, and the front end of back segment bar is provided with and the corresponding projection of said groove, and the projection of back segment bar extend in the groove of leading portion bar, and projection is connected through bearing pin with groove, is provided with the gap between projection and the groove.
Described leading portion rod rear end is provided with projection, and the front end of back segment bar is provided with and said projection corresponding grooves, and the projection of leading portion bar extend in the groove of back segment bar, is connected through bearing pin between projection and the groove, is provided with the gap between projection and the groove.
Because piston rod is arranged to the leading portion bar to the utility model and back segment bar two parts are formed; The leading portion bar is connected through connector with the back segment bar, and is provided with the gap at leading portion bar and back segment bar junction, and pile monkey is being beaten or during pile pulling; The power of vertical direction is cushioned by gap between the two when leading portion bar and back segment bar greatly; The back segment bar that is piston rod is unsteady with respect to the leading portion bar, and the back segment bar does not directly bear vertical force, has reduced frequent vibration.The seal that is provided with on the back segment bar has reduced the degree of wear to a great extent, has improved application lifes such as cylinder body, fairlead.
Description of drawings
Fig. 1 is the sketch map of the utility model.
The specific embodiment
Combine accompanying drawing that the utility model is further described, Fig. 1 is a kind of embodiment of the utility model at present, comprises a kind of pile holder tool of beating pile pulling equipment; Comprise piston, fairlead 16, piston rod and the clamping fixture seat 11 of cylinder body 12, band seal 20, described clamping fixture seat 11 is the columnar member of bottom band opening, is provided with installing hole in a side of clamping fixture seat 11; Fairlead 16 is installed in the installing hole; Cylinder body 12 and fairlead 16 are connected and are installed in the outside of installing hole, and piston is arranged in the cylinder body 12, and piston is connected with piston rod; Piston rod stretches out from fairlead 16 inside, and its front end is used for the folder stake.Described piston rod is made up of leading portion bar 18 and back segment bar 15; Leading portion bar 18 is connected with back segment bar 15 through connector; Seal 20 is arranged between back segment bar 15 and the fairlead 16, and the junction of leading portion bar 18 and back segment bar 15 is provided with gap
.
The rear end of leading portion bar 18 is provided with groove in the present embodiment; The front end of back segment bar 15 is provided with and the corresponding projection of said groove; The projection of back segment bar 15 extend in the groove of leading portion bar 18; Be provided with the gap between the front end of projection and the groove, projection is connected through vertically disposed bearing pin with groove.
The leading portion bar 18 and the back segment bar 15 of the utility model also can oppositely assemble with the foregoing description; Promptly be provided with projection in leading portion bar 18 rear ends; The front end of back segment bar 15 is provided with and said projection corresponding grooves; The projection of leading portion bar 18 extend in the groove of back segment bar 15, is provided with the gap between the front end of projection and the groove, is connected through vertically disposed bearing pin between projection and the groove.
The utlity model has rational in infrastructurely, can significantly reduce sealing part abrasion, prolong the characteristics in oil cylinder life-span.
