The working principle of the front clamp jack
The front clamp jack is a tool specially used for the tensioning and anchoring construction of prestressed projects. Its working principle is mainly based on the combination of hydraulic transmission and mechanical structure. The following is its specific working principle
Principle of hydraulic transmission
The working principle of the front clamp jack relies on the basic principle of hydraulic transmission, namely PASCAL's law. PASCAL's law states that when pressure is applied to a stationary liquid in a closed container, this pressure will be equally transmitted to all parts of the liquid. Therefore, through the pressure transfer of the liquid, different pressures can be generated on different end faces, so as to achieve force transfer and amplification
| Item | Unit | Value |
| Nominal tension | KN | 257 |
| Nominal oil pressure | MPA | 50 |
| Tension piston area | M2 | 5.137*10 |
| Return piston area | M2 | 1.335*10 |
| Piercing hole diameter | MM | 19 |
| Trolley trip | MM | 200 |
| Dimensions | MM | 180*568 |
| Return oil pressure | MPA | Less than or equal to 25 |
Structure and principle of action
The front clamping jack adopts the structural form of "static piston and moving cylinder body". When prestressing is applied, the piston and tension weighing sleeve of the jack remain stationary, while the outer cylinder liner, core sleeve, tool anchor and other components move backward relative to the piston. Tool anchors and tool clips hold the strand in this process and stretch it. When the required prestress value is reached, through the oil return operation, the outer cylinder liner, the core sleeve and other components are reset, while the working clip and the working anchor are automatically anchored, so as to complete the whole tensioning process
