Abstract
A hydraulic pile hammer belongs to a device class setting pile with a striking technique. The external rammer of the hydraulic hammer comprises an upper cylinder tube and a lower cylinder tube of the hydraulic pile hammer and an oil cylinder with required parameter, which is either formed by drilling at the center of a hammer lever or arranged at the lower half portion of the hammer lever after the processing molding, is arranged in the center position of the lower half portion of the hammer lever. The intracavity of the oil cylinder is a cavity shape formed by a slightly smaller and shorter cylinder and a bigger and longer cylinder. A piston rod seat, arranged at a lower hammer anvil, is connected with a piston, arranged inside of an activity cylinder. A piston rod is arranged on the piston rod seat and, together with the piston and piston pod seat center, is connected inside of the oil cylinder by a tubing channel. The tubing on the piston pod seat is connected with a tubing joint passed through the lower hammer anvil, which is connected with a pressure oil pump. A cushion, an upper anvil, a lower hammer anvil are arranged under the hammer lever inside of a lower cylinder in the order with a simple and compact structure, low cost and energy consumption.
Description
Technical field
The utility model relates to a kind of hydraulic pile hammer, belongs to the device class that stake is set with driving.
Background technology
The hydraulic pile hammer that the man introduction of foreign technology of domestic existing number is produced, it all is left and right sides in hammer body outside, each installs a hydraulic driving oil cylinder, and two pistons in two hydraulic jacks are upwards elected the top with the hammer stem in the hammer body together, the free drop impact pile tube fast of hammer stem.Elect driving by two oil cylinders, make hammer stem back and forth hit pile tube downwards, stake is driven underground.The hydraulic pile hammer of this pair of oil cylinder election driving mechanism is bulky, and heavy being difficult for moves, complex structure, and the manufacturing cost height, energy consumption is big.
Technology contents
The purpose of this utility model provides a kind of single cylinder top of lifting the hammer power set of simplifying and lifts the built-in type hydraulic pile hammer, the technical scheme that realizes above-mentioned purpose is that hydraulic jack, piston and piston pole socket all are contained in the Lower Half of hammer stem the inside, be provided with the passage of logical hydraulic oil in piston pole socket, piston and the piston rod, pile hammer is lifted on the single cylinder top.Its beneficial effect is, the built-in type hydraulic pile hammer is lifted on this single cylinder top, and is simple in structure, compact, cost is low, energy consumption is little.This structure can be made the large hydraulic hammer, also is suitable for doing the small-sized hydraulic hammer.Be provided with the passage of logical hydraulic oil in piston pole socket, piston and the piston rod of this hydraulic pile hammer, this structure decrease the oil line pipe of hammer outside, make hammer compacter, also shortened tubing length simultaneously, pressure oil directly enters cylinder cavity, has reduced the energy consumption of hydraulic jack.
Description of drawings
Accompanying drawing is the structural representation of the utility model, does not draw the supporting leg and the column on the right among the figure.
Each unit number is among the figure: go up cylinder barrel 1, hammer stem 2, oil cylinder 3, piston 4, piston rod 5, cushion pad 6, go up chopping block 7, piston pole socket 8, following hammer anvil 9, following cylinder barrel 10, cement pipe pile 11, oil connection 12, column 13, supporting leg 14, electric photosensitive elements N, S.
The specific embodiment
The utility model comprises cylinder barrel 1, hammer stem 2, oil cylinder 3, piston 4, piston rod 5, cushion pad 6, last chopping block 7, piston pole socket 8, following hammer anvil 9, following cylinder barrel 10, oil connection 12, column 13, supporting leg 14, last cylinder barrel 1 and following cylinder barrel 10 are formed the outer hammer body of hydraulic hammer, hammer stem 2 is contained in the cylinder barrel 1, hammer stem 2 Lower Half centers are for setting the oil cylinder of diameter, oil cylinder be hammer stem centre-drilling hole form or machine-shaping after be installed in the hammer stem Lower Half and all can, being shaped as of cylinder cavity is smaller, a slightly short cylinder is with bigger, the cavity shape that long cylinder links to each other and forms, piston pole socket 8 is installed in down on the hammer anvil 9, piston 4 links to each other with piston rod 5, piston 4 is placed in the cylinder 3 alive, piston rod 5 is installed on the piston pole socket 8, piston rod 5, piston 4 and piston pole socket 8 centers have the oil pipe passage to communicate with the cylinder cavity top, oil pipe in the piston pole socket 8 with link to each other by the following oil connection 12 of hammer anvil 9, oil connection 12 links to each other with pressure oil pump, cushion pad 6 is installed in down hammer stem 2 belows in the cylinder barrel 10, last chopping block 7 and following hammer anvil 9 are installed in cushion pad 6 belows, and last chopping block 7 is made of two semi-circular plates; 4 supporting legs 14 are arranged on the outer hammer body, and 14 of supporting legs hang on two root posts 13, and electric photosensitive elements N is arranged at outer hammer body top, and electric photosensitive elements S is also arranged at the bottom.Its course of work is: hydraulic pile hammer is installed on the cement pipe pile to be driven piles 11, following hammer anvil is connected with the cement pipe pile end face, when the hydraulic oil of oil pump output enters the top of hammer stem 2 inner cylinders through oil connection 12, piston pole socket 8, piston rod 5, piston 4, hydraulic oil produces the top that the election power that makes progress will go up the hammer stem 2 supreme cylinder barrels 1 in the cylinder barrel 1 between piston 3 and oil cylinder.At this moment hammer stem makes electric photosensitive elements N conducting, hydraulicdirectional control valve change direction, the change oil-feed on outer hammer body top be emptying, fluid flows out, hammer stem 2 impacts fast downwards cushion pad 6 in the cylinder barrel 10 down, goes up chopping block 7, hammer anvil down under the deadweight active force, and impact force is delivered on the cement pipe pile; When hammer stem 2 drops to the electric photosensitive elements S of the outer hammer body of when bottom conducting below, make hydraulicdirectional control valve change direction again, changes emptying is oil-feed, at this moment hammer stem 2 is again to rising, and hammer stem 2 reciprocal downward impact stake pipes like this reach the purpose of piling; Whole hydraulic pile hammer can move up and down along column, is convenient to piling.
