Abstract
The utility model relates to a manual locking device, which comprises: arranged from up to down in order, an upper fixing block, a connecting rod, a lower fixing block and an oil cylinder. A piston rod of the oil cylinder is hinged with the bottom of the connecting rod and the top part of the connecting rod is T-shaped so as to form a swing block. A locking spring which is used for keeping the state of the swing block when in vertical position is arranged in the upper fixing block. The upper fixing block is provided with a locking platform thereon, thereby the connecting rod is drawn tightly by the oil cylinder and the swing block is locked with the locking platform tightly when the swing block is arranged thereon. The part where the piston rod and the connecting rod are hinged is arranged in an open stop collar, and the width of the opening on a side wall of the stop collar is suitable for the connecting rod when swinging downward to thread through, thus having good position limitation effect and improved reliability.
Description
Technical field
The utility model relates to a kind of manual locking device, is specifically related to a kind of manual locking device that is used on wind electricity blade mould etc.
Background technology
Wind-powered blade mold is similar to casing, needs locking in use.Hand locking device structure complexity of the prior art, reliability is lower and use inconvenience.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, easy to use and reliability manual locking device preferably.
For solving the problems of the technologies described above, the utility model provides a kind of manual locking device, comprising: the last fixed block of upper and lower settings, connecting rod, fixed block and oil cylinder down successively; The piston rod of described oil cylinder and the bottom of connecting rod are hinged, the top of connecting rod is that T shape is to form swinging block, be provided with locking spring in the last fixed block, guarantee to keep when swinging block is in vertical position its state, last fixed block is provided with the locking table top, when placing above the described locking table top at described swinging block by described oil cylinder tension linkage and make swinging block and the locking of locking table top.
Further, the hinge portion of piston rod and connecting rod is arranged in the stop collar of open type, and the A/F on the sidewall of stop collar passes through when being suitable for the described connecting rod bottom, thereby plays position-limiting action preferably, improves its reliability.
Further, described locking table top is provided with the elastic damping plate that is used for the damped pendulum motion block, prevents the automatic bottom of swinging block when placing on the described locking table top at swinging block.
Further, described swinging block is provided with handle, operates to make things convenient for the workman.
Further, described locking table top has be arranged in parallel a pair of, and when swinging block placed on the described locking table top, described connecting rod placed this between the locking table top, to guarantee the reliability of locking state.
The utlity model has positive effect: the course of work of (1) this manual locking device is: in the time of directly over last fixed block places down fixed block, swinging block under the bottom state is upwards carried and is placed locking table top top, open oil cylinder and drop-down swinging block then, and make swinging block and the locking of locking table top; The piston rod that only need make oil cylinder when unblanking is to rising, then manually with swinging block to the bottom; Thereby manual locking and the function of unblanking have been realized.
