Description
Technical field
The present invention relates to hydraulic pile driver equipment manufacturing technology field, in particular to a kind of hydraulic hammer elastic connection and buffering
Control method and shock-damping structure.
Background technique
Currently, in building construction process, in order to keep building basis firm, it is often necessary to using hydraulic pile hammer, ram
The pile body of building is squeezed into certain depth by the hydraulic hammers class equipment such as real machine, quartering hammer on ground, allows the big portion of building
Point weight passes to the very deep position of below ground by stake, just can guarantee firm and anti-disaster the intensity of building.
In the prior art, the hydraulic hammer class equipment in China, such as the design and manufacturing technology of hydraulic pile hammer equipment, also compare
Fall behind.The reason is that the hydraulic hammer research and development in China are started late, just start related R&D work the 1990s.Domestic at present
Hydraulic pile hammer technology does not have competitiveness in the international market still.But with infrastructure projects such as a large amount of large-scale road and bridge, skyscrapers
The hydraulic pile hammer technology of the needs of construction, China obtains faster progress, especially in large-tonnage equipment aspect, but with
External sophisticated equipment is compared, working efficiency, stability, in terms of there is also a certain distance.
Existing single-acting hydraulic hammers class equipment into shape, and the hammer core of hydraulic hammer is mainly promoted to certain altitude by hydraulic device
After discharge, the gravitional force of pile hammer is converted into kinetic energy, by its free-falling impact in a manner of directly act on hydraulic hammer
On anvil block or pile cover, by hammering the direct effect of core and anvil block into shape, to do work to target pile body；After hydraulic hammer strikes strong object
Can high speed rebound, due to rebound process be it is instantaneous, oil cylinder is without time enough oil extraction, this tension weight churning instantaneously to rebound oil
Cylinder, and by oil cylinder impact hydraulic hammer shell, drive hydraulic hammer shell and with the associated equipment other parts one of hydraulic hammer shell
Bounce is played, strong vibration and noise are generated, is easy to cause hydraulic hammer shell and its related parts inside to damage or fail, together
When, the load bearing equipment for being easy that loading machine, excavator etc. is driven to connect with rack when hydraulic hammer shell rebounds acutely is shaken, it is accelerated
The fatigue of material and structure, shortens equipment life, and the comfort of operator is poor.
It is easy to ask what hammer body itself damaged to solve hydraulic hammer hammer body to the vibration generated after effective object effect
Topic, application for a patent for invention that number of patent application is 201710735454.7 " a kind of hydraulic hammer protective device and carry out hydraulic hammer
The means of defence of buffering ", by the way that buffer gear is arranged between oil cylinder and weight, pass through the double buffering group of spring and bolster
It closes, buffers the entire action process of weight effectively；In the period that weight falls, rebounds, there is enough or necessary sky
Between and technical measures, guarantee that cylinder piston rod continues deceleration downlink, piston rod made to have neither part nor lot in weight rebound process or be only involved in anti-
The later period rebound acceleration in the later period for bouncing journey, the process that rebounds significantly is decayed, or even tends to 0, simultaneously because evading or showing
Writing reduces weight rebound to the adverse effect of cylinder piston rod or the parts for being mounted on piston rod, cylinder piston rod and is mounted on
The parts of piston rod do not rebound or slightly rebound, and not only protect oil cylinder, also protect rack and with the associated equipment of rack its
His part, significantly improves the stability of whole device, improves the service life of each part of appliance indirectly.
Above-mentioned buffer structure includes hookup, spring, washer, connecting piece, gland, fastener, bolster, washer, lock
The more spare parts such as tight washer, need through above-mentioned multiple spare parts while work being assisted to provide buffering for hydraulic hammer hammer body
Function, structure design is also complex, lacks to the specific aim buffer protection of hydraulic hammer, simultaneously because its spare part quantity it is more,
Assembly relation is complicated, overall weight is also larger, high speed, high frequency time, large-tonnage piling work during, part spare part appearance
Easily there is fatigue, damage, so as to cause the global failure of the buffer structure, easily the overall structure of hydraulic hammer is damaged, together
When be also unfavorable for the maintenance and replacement in later period.
Therefore, it is necessary on the basis of above-mentioned technology again, be further improved and promoted；Especially designed improvement and control
The improvement of method be combined with each other, and improves working efficiency, stability to reach, extends the service life, and is suitable for large-tonnage
The demand of (500T or more) hydraulic hammer equipment.
