Abstract
A friction self-locking adjustment multipoint pressure equalizing type pile clamping mechanism comprises a hydraulic piston, a pile clamping box, a hydraulic rod, a slide block, a connecting rod, a pressing valve and a preformed pile. The hydraulic piston is installed on the pile clamping box, the hydraulic rod connected with the hydraulic piston is connected with the slide block, the slide block is in hinged connection with one end of the connecting rod, the other end of the connecting rod is in hinged connection with an outer side of the pressing valve, and an inner side of the pressing valve is contacted with the preformed pile extending into the pile clamping box. The friction self-locking adjustment multipoint pressure equalizing type pile clamping mechanism has the advantages of adopting a slide-block connecting-rod force increasing mechanism and being compact and simple in structure, large in force increasing ratio, stable in operation, simple in maintenance and the like.
Description
Technical field
The utility model relates to a kind of Pile holding mechanism of hydraulic static pile pressing machine, is that a kind of friction self-locking is regulated multiple spot even pressure type Pile holding mechanism specifically.
Background technology
Pile holding mechanism is one of component important in the hydraulic static pile pressing machine tool, is the final execution unit that piling machinery carries out the piling operation.It also is the important mechanism that is related to hydraulic static pile pressing machine efficiency of operation, the degree of depth, speed and security performance.Domestic existing static pile press generally adopts hydraulic cylinder to directly act on preformed pile and the piling mechanism that adopts scalene cone; The former active force is unequal; Force increasing ratio is little, the centering weak effect, and the latter has serious defective on the transmission efficiency of power; It is bigger to rub during heavy duty work, also big to the stress of casing.The Pile holding mechanism that improves hydraulic static pile pressing machine becomes increases middle problem demanding prompt solution in pile press tonnage and the efficient process.
The utility model content
In order to overcome the deficiency that above-mentioned technology exists, the utility model technical problem to be solved provides a kind of friction self-locking and regulates multiple spot even pressure type Pile holding mechanism, adopts the slide block connecting rod force-increasing mechanism to reach force increasing ratio purpose big, stable, simple in structure.
The technical scheme of the utility model is: a kind of friction self-locking is regulated multiple spot even pressure type Pile holding mechanism; Comprise hydraulic piston, pile clamping box, hydraulic stem, slide block, connecting rod, pressure lobe, preformed pile; It is characterized in that: hydraulic piston is installed on the pile clamping box, and the hydraulic stem that links to each other with hydraulic piston is connected with slide block, and an end of slide block and connecting rod is hinged; The other end of connecting rod is hinged with the pressure lobe outside, presses the lobe inboard to contact with the preformed pile that stretches into pile clamping box.
Said slide block can slide up and down along the pile clamping box inwall.
The minimum positive angle of said connecting rod and slide block track is greater than 45 ° and less than 90 °.
The utility model has the advantages that: this mechanism adopts the slide block connecting rod force-increasing mechanism, have that compact conformation is simple, force increasing ratio is big, stable, safeguard advantages such as simple.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Combine accompanying drawing at present, the technology contents of the utility model is described further.
As shown in Figure 1; Hydraulic piston 1 is installed on the pile clamping box 2, and the hydraulic stem 3 that links to each other with hydraulic piston 1 is connected with slide block 4, and slide block 4 is hinged with an end of connecting rod 5; The other end of connecting rod 5 is hinged with pressure lobe 6 outsides, presses lobe 6 inboards to contact with the preformed pile that stretches into pile clamping box 27.Wherein, slide block 4 can slide up and down along pile clamping box 2 inwalls; The minimum positive angle of connecting rod 5 and slide block 4 tracks is greater than 45 ° and less than 90 °.
During work, Pile holding mechanism promotes hydraulic piston 1 and through hydraulic stem 3 power is passed to slide block 4 under the effect of hydraulic oil, and slide block 4 produces reinforcement effect with pile clamping box 2 actings in conjunction in connecting rod 5 and promotes to press lobe 6 to clamp preformed pile 7.
