Disclosed in the present invention and background technology, the key distinction of two patents is:
1) a kind of foundation ditch controllable hydraulic bracing members disclosed in CN101463606A is contrasted, it itself is exactly bracing members end construction, self cylinder block acts directly on foundation ditch side wall, outside the cylinder block high to smoothness requirements is directly exposed to, the construction environment of camp site complexity and severe condition cannot be met, very easily cause cylinder body to draw, wipe, injure by a crashing object and seal failure cannot use; In addition, this is supported on short then one or two months, long then in the long-term pattern foundation pit supporting structure process of five or six months, must remain that hydraulic efficiency pressure system is in high pressure conditions, and without actv. self-locking measure, once there is the problem such as power-off, leakage of oil, to lose support effect, consequence is hardly imaginable.Finally, this support inside all has the hydraulic efficiency pressure system (comprising hydraulic reservoir, Hydraulic Pump, motor and hydraulic valve block) of complete set, and this just means that this hydraulic pressure support structure is very complicated, fragile, cost is very high and maintains loaded down with trivial details.
The present invention adopts postpone jacking in oil cylinder, and outer steel supports the structural form of cylindrical shell and segmented head integration, and possesses machinery+Hydraulic Double auto-lock function.Therefore, cylinder body is there will not be to expose support Problem of Failure that is fragile and that cause due to power-off or leakage of oil.In addition, the present invention is simple and reliable for structure, and only oil cylinder and related sensor, hydraulic lock are built-in, adopt outside unified hydraulic power system, not only substantially increase the fiduciary level of system, and economize on resources and can effectively reduce costs.
2) contrast after disclosed in CN203144059U and shore formula segmented head, its main deficiency is: first, its version adopts two sectional type structure, bolt with flange is adopted to be connected between its hydraulic pressure body with fixing body, complexity is installed, globality is poor, and when rear end oil cylinder loads in jack-in process, easily occur between hydraulic pressure body and fixing body, adopting bolt with flange tensile failure phenomenon; Secondly, the rear portion oil cylinder of this patent is without hydraulic lock and displacement pickup, once leakage of oil, oil cylinder lost efficacy immediately, and cannot monitor bracing displacement.In addition, the rear portion oil cylinder of this patent only has two hydraulic pressure transducers, its first hydraulic pressure transducer is connected to petrol storage tank monitoring mailbox pressure, second hydraulic pressure transducer is connected to hydraulic compressor sleeve or fixed muffle is used for monitoring steel bushing pressure, equal non-immediate test oil cylinder in-cylinder pressure, therefore directly accurately cannot measure axial force of the supports.Finally, its rear portion oil cylinder is fixedly connected with ball seat 44 by bolt with the 3rd connecting panel 45 of movable body rear end, and this connection mode seems feasible, in actual installation process, this region is in the closed region between hydraulic pressure body and fixing body, without operational space, cannot connect by bolt.
Described on end, the present invention's entirety adopts and controls and monitoring integration, and machinery is integrated with hydraulic pressure, be with machinery+Hydraulic Double self-locking pattern and the integral and intelligent informationization bracing members end construction with oil pressure and real-time displacement monitoring function.In use, can as required, loading and the axle power of carrying out axial force of the supports are easily added with, and to reach easy, Fast Installation supports, and improves operating efficiency, reduces the object of foundation pit deformation.The present invention carries mechanical type self-locking mechanism and hydraulic pressure self-locking device, achieves the reliable self-locking system of machinery, Hydraulic Double self-locking, avoids losing efficacy due to single self-locking and the destruction that causes and engineering accident.In addition, pressure sensor and displacement pickup that the present invention carries can be relied on, coordinate corresponding servo monitoring system, can realize controlling the real-time dynamic monitoring of bracing members axle power and distortion and intelligent automation.
Above-described embodiment is only for illustration of technological thought and the feature of this patent, its object is to enable those skilled in the art understand the content of this patent and implement according to this, the scope of the claims of this patent only can not be limited with the present embodiment, namely the equal change done of all spirit disclosed according to this patent or modification, still drop in the scope of the claims of this patent.
