The specific embodiment
Below with reference to the accompanying drawings, provide preferred embodiment of the present utility model, and be described in detail, enable to understand better function of the present invention, characteristics.
Fig. 2-5 shows an embodiment of the present utility model, in this embodiment, after shore the active head of formula and comprise hydraulic pressure body 1, hydraulic jack 2, fixedly body 3 and movable body 4, wherein,
This hydraulic pressure body 1 comprises the hydraulic compressor end flange 11 that be arranged in parallel and first connecting panel 13 that offers the first opening (not shown) in the center, and between this hydraulic compressor end flange 11 and first connecting panel 13 axially extended hydraulic compressor sleeve 12;
This hydraulic jack 2 is arranged in the hydraulic compressor sleeve 12 along the center shaft of hydraulic compressor sleeve 12, it comprises the petrol storage tank 21 of captiveing joint with hydraulic compressor end flange 11, this petrol storage tank 21 is connected to a peripheral hydraulic power unit by the oil pipe (not shown), and can be with respect to petrol storage tank 21 axially movable pistons 22, the one end is arranged in the petrol storage tank 21, and its other end is fixedly connected with a bulb 23;
Fixedly body 3 and the 1 co-axially align setting of hydraulic pressure body, it comprises the stay bearing plate that offers the through hole (not shown) 33 that be arranged in parallel and second connecting panel 31 that offers the second opening (not shown) in the center, and between this stay bearing plate 33 and second connecting panel 31 axially extended fixed muffle 32, wherein, described second connecting panel 31 is overlapping with described first connecting panel 13 and captive joint and described second opening and described first opening are axially aligned, body 3 is communicated with hydraulic pressure body 1 thereby make fixedly, passes for described bulb 23;
In the present embodiment, also be provided with first force bearing plate 34 that arranges along the diameter of this fixed muffle 32 in the fixed muffle 32, its dual-side is soldered to the inwall of fixed muffle 32, wherein, 31 first force bearing plates 34 from an end of the close stay bearing plate 33 of 31 fixed muffles 32 to the other end extend until with second connecting panel 31, the one section axial distance of being separated by, thereby between first force bearing plate 34 and second connecting panel 31, form a space 35, so that ball seat 44 can be made axial motion along this space 35.
Consult accompanying drawing again, between two strut bars 42 of movable body 4, also be provided with from movable end flange 41 outward extending second force bearing plates 43, and the setting of aliging with first force bearing plate 34 of this second force bearing plate 43.As shown in Figure 3, after movable body 4 is open, first force bearing plate 34 will separate with second force bearing plate 43, at this moment, filling one load cock body 7 between them, then this first force bearing plate 34 will transmit bearing force to second force bearing plate 43 by the load gag, thereby provide the mechanical force guarantee for shoring to act on.
In addition, the utility model also comprises first hydraulic pressure transducer 6 of petrol storage tank 21 outside faces that are connected to hydraulic jack 2 and second hydraulic pressure transducer 5 that is connected to hydraulic compressor sleeve 12, they all link to each other with a peripheral controllers by the data-interface (not shown), to give this peripheral controllers (not shown) with its measurement feedback, this peripheral controllers is regulated the delivery pressure of hydraulic jack 2 according to this value of feedback again, thereby realizes the real-time monitoring of the power of shoring and compensation automatically.
As shown in Figure 4, the fixedly body 3 of this enforcement preferably also comprises the side surface that is connected first force bearing plate 34 and the attaching parts 36 between fixed muffle 32 inwalls, this attaching parts 36 makes the force bearing plate 34 of winning more firm with being connected of fixed muffle 32, thereby increase the pressure that first force bearing plate 34 can bear, wherein, need be provided with the axial through bore (not shown) that the strut bar 42 for movable machine passes at this attaching parts 36.
The process of shoring of shoring the active head of formula behind the present embodiment is achieved in that at first promoting bulb 23 by hydraulic jack 2 axially travels forward, this bulb 23 promotes ball seat 44 again and travels forward, then this ball seat 44 again the strut bar 42 of promotion activity body 4 travel forward, after first hydraulic pressure transducer 6 detects pressure to arrive predetermined value (as shown in Figure 3), filling one load cock body 7 between first force bearing plate 34 and second force bearing plate 43, so that first force bearing plate 34 transmits pressure by this load gag 7 to second force bearing plate 43, thereby provide the mechanical force guarantee for shoring of foundation pit walls.
After having used load gag 7, active head imposes on the pressure of foundation pit walls except the pressure that comprises hydraulic jack 2 outputs, the mechanical force that also has load gag 7 to provide, so also need one second hydraulic pressure transducer 5 to measure this mechanical force in addition, to obtain the power of always shoring that this active head is applied.Because the mechanical force of load gag 7 is transmitted by first force bearing plate 34, and first force bearing plate 34 is captiveed joint with fixed muffle 32, fixed muffle 32 is captiveed joint with hydraulic compressor sleeve 12 again, interaction relationship according to power, therefore second hydraulic pressure transducer 5 is arranged on fixed muffle 32 or the hydraulic compressor sleeve 12 and can records the mechanical force that load gag 7 imposes on foundation pit walls, can record the hydraulic coupling that hydraulic jack 2 applies again by first hydraulic pressure transducer 6 simultaneously, so first, second hydraulic pressure transducer 5, during 6 combineds action, just can record and shore the power of always shoring that the active head of formula applies foundation pit walls after whole, the power of always shoring feeds back to a peripheral controllers by data-interface with this then, peripheral controllers is regulated the delivery pressure of hydraulic jack 2 according to this power of always shoring again, thereby realizes the real-time monitoring of the power of shoring and compensation automatically.
Above-described, be preferred embodiment of the present utility model only, be not in order to limiting scope of the present utility model, above-described embodiment of the present utility model can also make a variety of changes, and for example motor-driven can change handwheel into and drives.Be that simple, the equivalence that every claims according to the utility model application and description are done changes and modification, all fall into claim protection domain of the present utility model.
