Abstract
The present invention relates to the technical field of construction equipment, and concretely relates to a hydraulic pile hammer. The hydraulic pile hammer comprises a pile hammer drive device, the pile hammer drive device is internally provided with an oil cylinder, the oil cylinder is connected with a pile hammer, the pile hammer is connected with a hitting force transmission device, the hitting force transmission device is internally provided with a hitting pad, a rebounding cushion pad is disposed near the hitting pad, one end of the hitting pad is connected with a buffer pad layer, the buffer pad layer is connected with a pile cap, and the pile cap is disposed at one end of a pile. The hydraulic pile hammer has the functions of reducing strength of noises and adjusting impact stress, can weaken the maximum hitting force and reduce pile damages, and is simple and convenient to operate and easy to popularize.
Description
Technical field
The present invention relates to building implements technical field, be specifically related to a kind of hydraulic pile hammer.
Background technology
Along with the development of builing industry, construction method and the construction machinery of pile foundation also change thereupon.The classification basic forming of stake, is divided into preformed pile and in situ pile.Wherein preformed pile is because good environmental adaptability, and construction is simple, and efficiency is high, uses more and more extensive.Prefabricated pile basis construction machinery mainly contains diesel hammer, vibrohammer, hydraulic static piling machine and hydraulic hammer, and when diesel hammer works with vibrations pile monkey, noise is comparatively large, and use is restricted, static pile press due to manufacturing cost high, equipment is huge, dismounting and transport difficult, and its popularization is also restricted.And hydraulic pile hammer is because its low cost of manufacture, volume is little, and efficiency is high, and noise is low, takes the course of its own in piling machinery.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of flexible and convenient operation, the efficient hydraulic pile hammer of cost-saving operating efficiency.
For solving the problems of the technologies described above, the invention provides following technical scheme: a kind of hydraulic pile hammer, comprise pile hammer drive unit, be provided with oil cylinder in described pile hammer drive unit, described oil cylinder is connected with pile monkey, described pile monkey is connected with hitting power transfer device, be provided with percussion pad in described hitting power transfer device, described percussion pad is other is provided with resilience cushion pad, and described percussion pad one end is connected with cushion, described cushion is connected with pile cover, and described pile cover is provided with one end and is provided with stake.
On such scheme basis preferably, described pile monkey is spherical.
On such scheme basis preferably, described pile monkey is hollow, and inside is filled with granular metal.
On such scheme basis preferably, the width of described stake accounts for the 1/4-1/5 of hitting power transfer device.
On such scheme basis preferably, the volume of described oil cylinder is 100 liters.
On such scheme basis preferably, described cushion adopts rubber or bakelite material.
Prior art of the present invention compares the beneficial effect had: the pile monkey of hydraulic pile hammer is hollow, inside is filled with granular metal, activity coefficient is less than 1, when pile monkey accelerates, granular metal is free-falling, thus lag behind pile monkey and present " floating " state, when pile monkey contacts again by resilience cushion pad with percussion pad, slow down after cushion, and then when forming bounce-back trend by shock, granular metal falls successively, effectively can slow down the vibration of pile monkey, in addition, the application of granular metal extends impact process, effectively increase the injection amount under one-shot, thus the energy conversion rate of impact process can be significantly improved, percussion pad is between pile monkey and anvil, cushion is between pile cover and stake, the direct shock of metal can be prevented, reduce the intensity of noise, regulate impact stress, cushion adopts rubber pad or bakelite plate as padded coaming, certain storage impact energy can be played, weaken maximum hitting power, reduce the effect that stake damages.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Number in the figure is: 1-oil cylinder, 2-pile monkey, 3-percussion pad, 4-resilience cushion pad, 5-cushion, 6-pile cover, 7-stake, 8-hitting power transfer device, 9-pile hammer drive unit.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In describing the invention, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the present invention for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as limitation of the present invention.
Known with reference to Fig. 1, a kind of hydraulic pile hammer, comprise pile hammer drive unit 9, be provided with oil cylinder 1 in described pile hammer drive unit 9, described oil cylinder 1 is connected with pile monkey 2, described pile monkey 2 is connected with hitting power transfer device 8, be provided with percussion pad 3 in described hitting power transfer device 8, described percussion pad 3 is other is provided with resilience cushion pad 4, and described percussion pad 3 one end is connected with cushion 5, described cushion 5 is connected with pile cover 6, and described pile cover 6 is provided with one end and is provided with stake 7.
Further, described pile monkey 2 is spherical.
Further, described pile monkey 2 is hollow, and inside is filled with granular metal.
Further, the width of described stake 7 accounts for the 1/4-1/5 of hitting power transfer device 8.
Further, the volume of described oil cylinder 1 is 100 liters.
Further, described cushion adopts rubber or bakelite material.
The pile monkey 2 of hydraulic pile hammer is hollow, and inner volume is filled with granular metal, and activity coefficient is less than 1.When pile monkey 2 accelerates, granular metal is free-falling, thus lags behind pile monkey 2 and present " floating " state.Slow down when pile monkey contacts after again by resilience cushion pad 4, cushion 5 with percussion pad 3, and then when forming bounce-back trend by shock, granular metal falls successively, effectively can slow down the vibration of pile monkey.In addition, the application of granular metal extends impact process, effectively increase the injection amount under one-shot, thus can significantly improve the energy conversion rate of impact process, percussion pad 3 is between pile monkey 2 and anvil, cushion 5 is between pile cover 6 and stake, the direct shock of metal can be prevented, reduce the intensity of noise, regulate impact stress, cushion 5 adopts rubber or bakelite as padded coaming, the effect of stake damage of can playing certain storage impact energy, weaken maximum hitting power, reduce.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
