A hydraulic power mechanism and a vibrating body in the pressure mechanism are both installed in a frame 4. A stander 5 is installed on the machine body 9. The frame 4 is installed in the stander 5 and has an upper and lower sliding connection with a slideway 5-1 above the frame. The upper part of the frame is suspended from a transverse plate 8 of the frame and the lower part of the frame is provided with a pile cap 7. The vibrating body 1 is connected with the pile cap via a vibrating bar 3 located in the center of the frame 4.

Description
Technical field
The utility model relates to a kind of Static pressure pile driver that has no synchronous vibration, and it belongs to the system stake equipment that uses in the civil works.
Background technology
At present, the Static pressure pile driver Ground Treatment, in order to add the bearing capacity of timber pile, the mode of employing is the volume that adds the timber pile machine, increases the counterweight of stake machine, has so just increased the difficulty and the expense of carrying, and is higher to the original requirement for bearing capacity on the ground that is reinforced ground.When sliding stake, can produce very big influence to building on every side.In existing Static pressure pile driver, owing to do not have vibrating body, thereby when piling, the influence that changed by formation resistance, particularly in the sand bed construction, penetration capacity is relatively poor.
Technology contents
The purpose of this utility model is: a kind of Static pressure pile driver with no synchronous vibration body is provided, hydraulic pressure and vibration are combined, adopt the hydraulicefficiency telecontrol ungraded amplitude, the frequency adjustable of vibrating body, can avoid the resonance region of pile frame, ground, pile body, Static pressure pile driver rational in infrastructure.
The technical solution of the utility model is: this Static pressure pile driver that has no synchronous vibration is made of stake machine body, pressing mechanism, hydraulic system, electrical system, hydraulic power mechanism in the pressing mechanism and vibrating body are installed in the framework 4, frame 5 is installed on body 9, framework 4 is loaded in the middle of the frame 5, can slide up and down with slideway 5-1 on it and to be connected, framework upper hangs on frame transverse slat 8, and piling cap 7 is arranged at the framework bottom.
Described Static pressure pile driver, its vibrating body 1 is connected with the piling cap by the vibrating arm 3 that is positioned at framework 4 centers, and the hydraulic jack 2 of the hydraulic power mechanism vibrating arm both sides that are placed in are connected with the piling cap by pile cap plate 6.
Described Static pressure pile driver, the vibration frequency of vibrating body 1 are that 0～40HZ is adjustable, and amplitude is that 0～15mm is adjustable.
The described Static pressure pile driver that has no synchronous vibration, the vibration frequency of its vibrating body is adjusted into 6～8HZ, and amplitude is 5～15mm.
The described Static pressure pile driver that has no synchronous vibration, the vibration frequency of its vibrating body is for adjusting 8～15HZ, and amplitude is 5～15mm.
The described Static pressure pile driver that has no synchronous vibration, the vibration frequency of its vibrating body are adjusted into adjusts 18～25HZ, and amplitude is 5～15mm.
The described Static pressure pile driver that has no synchronous vibration, the vibration frequency of its vibrating body is adjusted into 20～30HZ, and amplitude is 5～15mm.
The described Static pressure pile driver that has no synchronous vibration, the vibration frequency of its vibrating body is adjusted into 25～40HZ, and amplitude is 5～10mm.
The utility model stake machine has the following advantages:
1, adopted vibrating body to combine with hydraulic pressure, penetration capacity is strong, and particularly the penetration capacity to sand bed is particularly remarkable.
2, the frequency adjustable of vibrating body, the frequency height, volume is little, and exciting force is big.
3, because vibrating body has been avoided the resonance region of pile frame, ground, pile body in design, therefore stake, equipment and surrounding buildings thing there is not destroying infection.
4, because what vibrating body was adopted is the hydraulicefficiency telecontrol ungraded amplitude, avoided the resonance region with other object again, therefore, and noiselessness during vibration, vibration wave is depleted fast, and the vibration sense is little, and is noiseless to the townsfolk.
5, owing to adopted no synchronous vibration body, can produce very big exciting force, therefore, avoid satisfying the bearing capacity of stake with the method that constantly increases Static pressure pile driver own wt or increase counterweight.Certain in requirement for bearing capacity, under the identical condition of place soil property, can reduce a machine own wt or a counterweight, under the effect of static(al) and exciting force, can improve the piling ability widely.When construction, can reduce the grounding pressure of a machine, avoid because of the heavy damage of stake machine to underground pipeline and underground object.And reduced freight volume.
Description of drawings
Fig. 1 is the Static pressure pile driver assembly that has no synchronous vibration of the present utility model.Fig. 2 does not have the vibrating body of resonance and the modular construction figure of vertical static pressure for band.Shown in the figure: the track 5-1 on vibrating body 1, static(al) oil cylinder 2, vibrating arm 3, framework 4, pulley 4-1, frame 5, the frame, pile cap plate 6, pile cover 7, frame transverse slat 8, body 9, pile body 10, ground 11.
The specific embodiment
As shown in Figure 1, in the ordinary course of things, hydraulic power mechanism among Fig. 2 and vibrating body are installed in the framework 4, frame 5 is installed on body 9, framework 4 is loaded in the middle of the frame 5, total is suspended on by wire rope on the frame transverse slat 8 of frame 5, cooperates and can move up and down with track 5-1 on the frame by pulley 4-1.Its vibrating body 1 is connected with the piling cap by the vibrating arm 3 that is positioned at framework 4 centers, and two static(al) oil cylinders 2 of the hydraulic power mechanism vibrating arm both sides that are placed in are connected with the piling cap by pile cap plate 6.The vibration frequency of vibrating body 1 is that 0～40HZ is adjustable, and amplitude is that 0～15mm is adjustable.When frequency is adjusted into 20～40HZ, can avoid various resonance.Certainly, the frequency adjustment is decided by ambient conditions.
During work, under the effect of static(al) oil cylinder 2, carry out piling.When meeting obstructions layer or sand bed, under hydrostatic power pressure, stake is difficult to depress, at this moment, make vibrating body 1 beginning exciting, when vibration frequency is selected the above high frequency of 20HZ by remote control, exciting force is big and do not have resonance, pass to pile body 10 by vibrating arm 3, and move simultaneously, until the penetration resistance layer with the top pile-pressing machine structure.Make stake under the acting in conjunction of high-frequency excitation power and silent piling oil cylinder 2, very fast stake is pressed into ground 11.2 meters of each runs when piling body 10 is depressed 2 meters the time, are mentioned the total among Fig. 2 by wire rope, carry out next step cycling.
