Features: small size, light weight, large bearing capacity, good safety and reliability, high degree of automation, convenient and flexible operation.
Uses: Large components are continuously promoted synchronously along the track.
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
Pushing Process:1.The rail clamp is fixed on the track, and the pushing cylinder is mounted on the heavy load. 2.The pushing cylinder extends its piston. 3.The rail clamp releases, the cylinder retracts fully, and then clamps the track again.
The rail-clamp synchronized pushing hydraulic system has been successfully applied in various fields such as bridges, railway stations, stadiums, and museums, demonstrating stable performance.
