Description
Technical field
The present invention relates to engineering technology detection technique field, certainly apply more particularly, to a kind of high strain monitoring super large hammer
Beat device and using method.
Background technology
High strain monitoring, is to use tension weight churning stake top, surveys speed and the power time-history curves in stake top portion, by wave theory
Analysis, the detection method that single pile vertical resistance pressure bearing capacity and pile body integrity are judged.High strain monitoring method at this stage
During detection foundation pile, in order that producing certain relative displacement between stake soil, need effect in stake to have larger energy it is therefore necessary to
Hammer stake top with weight, weight produces larger impulsive force needs the lifting of certain altitude.
Weight mostly at tens tonnes not, needs large-scale crane that weight is lifted when being tested at this stage,
But because weight breaks off relations in a flash, lead to crane load acute variation, larger impact is produced to crane, can be to lifting
Machine structure produces to be damaged.Simultaneously because crane not have limiting structure that hammer body is carried out in lifting process spacing, may lead
Cause hammer body axis misaligned with tested pile foundation axis, carry out test and can lead to tested pile foundation discontinuity, impact is high should
Become the accuracy of test.Simultaneously because charges for using winch is higher, certain impact can be produced on benefit, affect practicality.
The present invention is to overcome the problems referred to above, provides a kind of high strain monitoring super large to hammer into shape from injection device, has use cost
Feature low, convenient and swift, that practicality is high.
Content of the invention
The present invention is at least one defect overcoming described in above-mentioned prior art, provides a kind of high strain monitoring super large hammer certainly
Injection device and using method are it can be ensured that have the characteristics that during using that use cost is low, convenient and swift, practicality is high.
For solving above-mentioned technical problem, the technical solution used in the present invention is：A kind of high strain monitoring super large is hammered into shape from injection
Device, include hammer carrier it is characterised in that：Described hammer carrier is provided with hydraulic lift, is provided with and hydraulic lifting system in hammer carrier
The pulley assembly that system connects, is arranged on the interior tripping gear on pulley assembly, is connected outside hammer carrier and with interior tripping gear
Outer tripping gear, hydraulic lifting system realizes hammer body lifting by pulley assembly, and interior tripping gear and outer tripping gear pass through
Hammer body lifting is realized automatically-unhooked and automatic hanging and is played weight.
The present invention provides a kind of new high strain monitoring super large to hammer into shape from injection device, located at the hydraulic lifting at hammer carrier top
System can substitute the function of lift, realize the simplification of single unit system and reduce use cost.Pulley within located at hammer carrier

Assembly pulley can move up and down in hammer carrier, and hydraulic lift can be facilitated to realize laborsaving work(to while the lifting of hammer body
Can, improve device practicality.
Preferably, running block is provided with the stopping means chimeric with hammer carrier.
Due to running block be mainly used to lifted hammer body, therefore running block can stablize lifting determine hammer body can be steady
Fixed lifting.Running block arranges stopping means, running block can be limited in certain scope, improve device fortune
Stability in row.
In one embodiment, interior tripping gear is provided with two the first arms with crotch that can be dynamically connected, with the first arm
The second arm that can be dynamically connected, the second arm can be dynamically connected with running block.
Can the structures shape of interior tripping gear automatic unhooking function be realized well.Interior tripping gear is set to scissors
Shape, the first arm carries crotch and being dynamically connected, and two the first arms being capable of flexible rotating each other.Can be dynamically connected on first arm
There is the second arm, can flexibly rotate between the second arm and the first arm.The one end being therefore connected with running block in the second arm is consolidated
In the case of fixed, interior tripping gear is capable of contraction and the stretching, extension of itself, realizes automatically taking off during contraction and stretching, extension
Hook and the function of automatic crawl, have considerable flexibility during use.
Preferably, the movable junction of two the first arms is connected with unhook assembly pulley.
Unhook function could preferably be realized because interior tripping gear and outer tripping gear cooperate, in two the first arms
Can junction connect unhook assembly pulley can preferably be connected with outer tripping gear, simultaneously unhook assembly pulley can pass through outer take off
Hook device drive in tripping gear mass motion, preferably realize automatically-unhooked and automatic hanging and play weight.
In one embodiment, outer tripping gear is provided with the fixture being connected with the assembly pulley that breaks off relations, and fixture can be with hammer carrier
The fixing groove being provided with is fitted together to.
Traditional device is realized needing manually to apply pulling force to suspension hook from injection, therefore can cause a lot in use
Inconvenience and potential safety hazard.The present invention passes through the cooperation of fixture and fixing groove, during interior tripping gear declines automatically
Apply pulling force, can automatically realize from the function of breaking off relations without artificial operation, practicality is high.
In one embodiment, hammer body is provided with gathering sill, is provided with guide rail in hammer carrier.
In order to make hammer body smoothly move in hammer carrier, it is provided with guide rail in hammer carrier, hammer body is provided with gathering sill, energy
Enough realize the restriction effect to hammer body it is ensured that hammer body is steady in motion process in hammer carrier, the even running energy of hammer body simultaneously
Enough accuracies ensureing detection.
In one embodiment, hydraulic lift adopts hoist engine.
Hydraulic lift needs larger hoisting power, simultaneously in order to adapt to the less space in hammer carrier top,
The function of being lifted can preferably be realized from hoist engine, hoist engine floor space is less simultaneously, convenient transportation, it is possible to increase dress
The overall utility put.
Instant invention overcomes the use cost of conventional apparatus is big, save the artificial operation of unhook, have use cost low,
The high feature of simple to operate, practicality.
