Description
Technical field
The utility model relates to pile foundation construction equipment hydraulic static presses extractor, particularly hydraulic static to press two clampers of extractor.
Background technology
Hydraulic static pile pressing machine is a large amount of construction equipments that use in the prior art pile foundation construction.It has characteristics such as noiselessness, pollution-free, construction safety, speed of application be fast, is subjected to constructor's favor.Hydraulic static pile pressing machine divides top pressing type and hugging pressure type two big classes, what wherein the hugging pressure type hydraulic static pile pressing machine used is more, the piling Beam of this pile press is provided with a lag pile pepe gripper or two lag pile pepe grippers, the driving oil cylinder of clamper is to be designed to drive piling with big oil pocket mostly, reset with the small oil cavity driving, like this, need press not only but also during pile pulling, ability to work just can not meet the demands when running into.Stake pepe gripper structure is too simple simultaneously, and servo-actuated is not enough, and it is not strong to add the power of holding, and presss from both sides bad pile body easily.Chinese patent 00128145.2 He all is such hydraulic static pile pressing machine.
The utility model content
The purpose of this utility model is to propose a kind of construction requirement that can satisfy pressures, pile pulling on hydraulic static pile pressing machine, again can series, parallel or two Beam brute force pepe gripper of independent piling.
The utility model is to realize like this.It mainly is made up of piling Beam, stake pepe gripper and piling oil cylinder.Its pepe gripper divides two groups up and down, and the following clamping frame of following stake pepe gripper is connected with piling Beam by the lower piston pole socket, and piling cylinder body is installed on the piling Beam under it; The last clamping frame of last stake pepe gripper is connected with piling Beam by the upper piston pole socket, and piling cylinder body is installed on the clamping frame on it; At clamping frame inner face fixedly skewback of single face has been installed, fixedly on the skewback two-sided skewback, the movable skewback of single face, grip block inwardly have been installed also radially at single face, the clamping cylinder that drives two-sided skewback is housed on the top of two-sided skewback, their covers are formed the skewback clamping device, and one or more sets skewback clamping devices are set on each clamping frame.
The movable skewback of the single face of described skewback clamping device is provided with sphere and is connected with grip block, and with the tension of butterfly spring device, the grip block inner headed face is provided with the arc surface that adapts with stake pipe outer wall between movable skewback of single face and the grip block.
According to the requirement of construction, grip block can be designed to the shape of the various stake of clamping type.
The utility model can only be installed a stake pepe gripper.
The course of work of the present utility model is such.The pepe gripper of stake up and down of the present utility model can work independently also can associated working.Because down the piling cylinder body is installed on the piling Beam, last piling cylinder body is installed on the clamping frame, during therefore with following pepe gripper piling is to pressurize with the big chamber of piling oil cylinder down, and is that under using pressurize in the loculus chamber of piling oil cylinder during pile pulling; In the use stake pepe gripper press, just in time opposite during pile pulling.So use that stake pepe gripper is pressed, during pile pulling, general with following pepe gripper piling, use a pepe gripper pile pulling and be advisable.When using two stake pepe grippers pressures, pile pulling, two stake pepe grippers are all worked.
When their series connection pilings, be down the piling of stake pepe gripper, go up stake pepe gripper backhaul preparation, following piling finishes, and last piling begins immediately, and circulation is carried out, and improves piling speed and efficient.
When their pilings in parallel, be down the piling of stake pepe gripper and work simultaneously, pile driving pressure is double, improves the piling ability greatly.
The single face activity skewback of the utility model skewback clamping device is provided with sphere and is connected with grip block, and grip block can be followed the servo-actuated of stake pipe outer wall like this, makes clamping efficient better, and it is more firm to clamp, and makes invention more effective when satisfying the pressure pile pulling.
The utility model is simple in structure, connection and reasonable arrangement, and the efficient height can satisfy pressure, pile pulling requirement in the pile foundation construction preferably.
