otaku是什么意思摘要：A fail-safe locking device for reel support systems is described which is suitable for u with reels such as tho ud with wire stranders and similar machines. In the embodiments described, a pintle supporting shaft member is normally biad by a spring to an extended position. A safety plunger is provided which has a stepped exterior surface so as to define a recess or step. The safety plunger is normally biad by a spring to a disabling position to urge a blocking member, such as a hardened steel ball or sphere, into the path of movement of an abutment surface of the shaft member to automatically and positively lock the shaft member and the pintle. In the locked condition, the plunger member and, therefore, the pintle, cannot accidentally relea the reel. The shaft member and the safety plunger are provided with bearing surfaces against which a fluid medium under pressure may be applied by an operator of the machine to, firstly, move the safety plunger from the disabling to an enabling position to permit the ball or sphere to drop into the recess or notch and, therefore, out of the path of movement of the shaft member abutment surface. Once freed, the plunger member is urged by the fluid medium under pressure to a retracted or releasing position. Two opposing pintle asmblies may be mounted on a cradle typically ud in wire stranders,
and pneumatic pressure is ud by the operator to relea the fail-safe locking system to accept or r
elea a reel from the cradle. Electrical means may be ud for monitoring the position of the safety plunger and for disabling the machine or issuing an alarm upon movement of the safety plunger to its enabling position and, thereby, permitting the plunger member and pintle to move to a retracted position. The fail-safe locking device is also shown on other reel-supporting systems such as bobbin supporting shafts.
