Advanced walking type continuous pushing action, fast pushing speed, stable and reliable moving action.
Ultra high pressure hydraulic technology, with small size and light weight, convenient for field installation and disassembly.
Using frequency conversion synchronous control mode, the speed is accurately adjustable, and has the characteristics of displacement and force double closed-loop synchronous control.
Through perfect hydraulic control and point arrangement, the vertical supporting force of each pier top can be adjusted and balanced automatically, making the pushing more safe and reliable.
The whole equipment can adjust the attitude of the whole bridge in space.
Single device can realize independent movement in X, y and Z directions without mutual interference.
Clamp Rail Type Synchronous Pushing Hydraulic System is mainly used for synchronous push-slide construction of large components. The jacking and sliding of traditional large-scale components mainly adopts the winch, pulley block and steel wire rope for traction. The traction force and traction speed are difficult to control, and the sliding member shakes greatly, the seating accuracy is low, and the safety is poor. Under such technical background, KIET has developed a kind of thrust equipment with self-clamping of heavy-duty rails —Clamp Rail Type Synchronous Pushing Hydraulic System. It mainly consists of hydraulic pushing pump station, hydraulic cylinder, and self-locking crawler , Wedge block, sliding shoe and other components, the crawler is installed on the track through the clamping seat, and the telescopic action of the hydraulic cylinder makes the wedge block and the clamping rail automatically form a reaction force device, which finally realizes the synchronous pushing of large components make.
Self-locking clamping device, save the reinforcement of the reaction force frame, save time and effort
The push cylinder is rigidly connected with the pushed member, high synchronization control accuracy
Multi point simultaneous pushing can be used to reduce local stress of multi-component and prevent component damage
By changing the shape and size of wedges, various specifications and models of tracks can be realized
The installation is convenient and quick, and the construction process is followed automatically to reduce the construction period
The cylinder is slowly loaded and pushed at a uniform speed. The construction process is stable, avoiding the impact of the start and stop process, and effectively protecting the stability of the steel structure
During the construction process, the displacement and pressure of each pushing point can be displayed and controlled in real time to ensure the safety of site construction
