Embodiment Construction
[0023] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0024] The specific embodiment of the spring operating mechanism adjustment tooling of the present invention is as figure 1 and figure 2 As shown, the spring operating mechanism in this embodiment includes a spring barrel 2 and a spring installed in the spring barrel 2 and a spring tray 5, the spring barrel 2 is fixed on the spring barrel support 3, and the spring barrel 2 is also provided with a spring pressure pole 12. The spring in this embodiment is a combination spring 9, and in other embodiments, the spring can be a single spring. The spring barrel 2 is provided with a screw rod 8 with one end fixed on the chain rod joint 10 and the other end protruding from the spring tray 5 . The screw rod 8 is connected with a pre-tightening nut 7 and a lock nut 4 to prevent the pre-tightening nut 7 from loosening, and the pre-tightening nut 7 presses the sp...

The invention relates to a spring operating mechanism and an adjustment tool thereof. The spring operating mechanism comprises a spring cylinder, a spring and a spring tray, wherein the spring and thespring tray are arranged in the spring cylinder, a screw rod is arranged in the spring cylinder and extends out of the spring tray, a top press spring tray is connected to the screw rod to pre-tighta pre-tight nut of the spring, a locking nut is further connected to the screw rod and is used for preventing the pre-tight nut from being loosen, and the external diameter of the locking nut is smaller than the external diameter of the pre-tight nut. The external diameter of the locking nut is smaller than the external diameter of the pre-tight nut, the locking nut is loosen at a certain distanceby the locking nut cylinder matched with the locking nut during adjustment of pre-compression quantity of the spring, the locking nut is adjusted to an appropriate position by the pre-tight nut sleeve matched with the pre-tight nut, the locking nut is tightened, and during the whole adjustment process, the locking nut is not needed to be assembled and disassembled; and the problem of spring pre-compression quantity adjustment process complexity when the locking nut and the pre-tight nut are arranged on the screw rod in the prior art is solved.
Description
technical field [0001] The invention relates to a spring operating mechanism and its adjusting tool. Background technique [0002] In high-voltage electrical switch products (GIS, open circuit breakers, etc.), all driving mechanisms need to be characterized according to the performance parameters of the circuit breaker. For a mature spring operating mechanism, the main means of performance adjustment is to adjust the opening and closing energy, matching the opening and closing energy, and at the same time meeting the requirements of the circuit breaker for speed, time and other performance parameters. . In the past, spring energy adjustment tools either adopted complicated and electric adjustment methods, which were not easy to carry, install, assemble and debug; or adopted simple mechanical structures, which were easy to carry, but the assembly and debugging process was complicated, time-consuming and laborious, and safety performance was difficult to guarantee.
