Compared with prior art, the utility model has following useful technique effect:
The utility model to be connected each execution unit by control assembly and unifies, and that can unify to transformer core and coordinate carries out compression operation, ensure that quality and the efficiency of compression; Bracing frame is fixedly connected on the piston rod top of hydraulic cylinder, makes bracing frame become as a whole with hydraulic cylinder, thus increase the stability of whole system, avoid bracing frame generation in During prolonged operation and rock and the problem of Wear System, its fail safe is higher; Meanwhile, steel wire rope can be walked around transformer core and be connected with closed behind bracing frame top, makes whole system stability stronger, improves security reliability and the operating efficiency of tightening device.What adopt hydraulic oil pump to control whole system tightens up operation, and simple to operate, have higher transmission efficiency, operating efficiency is high, and tightens up effective, efficiently solves the problems such as the error that adopts manual operation to bring and iron core can not tighten up completely.And by adopting the mode of multiple hydraulic cylinder operation simultaneously, make transformer core stressed evenly, ensure that iron core entirety tightens up the consistency of effect, indirectly improve the useful life of transformer core under not by the impact of human factor.
Further, the pipeline road of hydraulic oil pump is provided with total valve, and the high-pressure oil pipe of each hydraulic cylinder is installed respectively hydraulic pressure valve along separate routes, each hydraulic cylinder can realize independent control, can local directed complete set when running into special circumstances, operation is more flexible, substantially increases the safety and reliability of whole system.In addition, hydraulic oil pump is provided with pressure fuel pump display unit, make system more accurate to the control of iron core tightening force when operation, the feedback of information is more direct, eliminates the error that manual operation brings.
Further, bottom hydraulic cylinder, be also equipped with the adjustment backing plate that some groups of thickness is different, can according to the next gap between flexible iron core and hydraulic cylinder of practical application, what ensure transformer core tightens up effect, applied widely.
Further, regulate backing plate to adopt phenolic board to make, dimensionally stable rate of change is little, can effectively ensure to tighten up effect and minimizing is rocked, and ageing-resistant performance is good simultaneously, and cost is low.
Further, be symmetrically arranged with two arc grooves on bracing frame top, for limiting the steel cable sliding degree of freedom, improve steel wire fixing and being connected, good stability after winding is closed, safe and reliable, what effectively ensure whole system tightens up effect.
Further, adopt overall ironcasting to make bracing frame, bracing frame the is had advantage such as wear-resisting, damping, processing performance be good, effectively can ensure the stability of bracing frame, what produce after avoiding long-term operation rocks, and increases work efficiency.
