Set and sprocket wheel, sprocket wheel is by being keyed on axis；In lockable mechanism, oil cylinder top is equipped with locking frame and brake-rod support, locking frame
With brake-rod support and oil cylinder as one, locking frame is rectangular frame shape, is equipped in rectangular frame shape and unloads compression bar, unloads compression bar lower part
It is that cylindrical bar is extend into oil cylinder, is the switch of cylinder efficient, unloading compression bar can moves up and down there are two position: it is upper and the next,
Compression bar is unloaded when the next and is pressed downwardly onto bottom, is cylinder efficient state, and oil cylinder drive rod moves up and down the stretching of drive cylinder bar；It is upper
When unload compression bar and be lifted up, be oil cylinder pressure release state, oil cylinder drive rod is ineffective；Compression bar middle and lower part is unloaded equipped with cuboid, length
It is equipped with oval-shaped slot in cube, the restrictor bar head of locking restrictor bar end is placed in oval-shaped slot, restrictor bar head can be slided in oval-shaped slot
It is dynamic；Unloading compression bar top is cylindrical bar, and cylindrical bar upper end is equipped with threaded hole, is cased with locking handle outside cylindrical bar, on locking handle
Equipped with counterbore, locking screw is installed in counterbore, locking screw is screwed into the threaded hole for unloading compression bar and unloads compression bar and connect；Locking
Handle lower end is cylindrical tube, is equipped with locking positioning pin in the middle part of cylindrical tube, locking positioning pin is the cylinder of evagination, locking handle
Cylindrical tube can rotate around compression bar is unloaded and release bar can be driven to move up and down, and locking frame upper end is equipped with semicircle locating slot, unload compression bar
When being pulled to upper, then 90 degree are rotated clockwise, locking positioning pin is put into locating slot, and the upper of compression bar is unloaded in locking；Locking lock
Bar is long rod-shape, is hinged on above the brake-rod support of oil cylinder by locking pin, and locking restrictor bar can be rotated around locking pin, locking
Restrictor bar right end cylinder rod is equipped with ratchet, when locking restrictor bar is rotated clockwise to the spine on the ratchet and cylinder rod on locking restrictor bar
When tooth is overlapped, cylinder rod is lockable not flexible；Locking spring is cased on the outside of the cylindrical tube of locking handle, locking spring is compression
Spring, lower end are contacted over the cuboid for unloading compression bar, and upper end is withstood on the transverse slat of locking frame, and unloading compression bar can be in locking spring
Under the action of be forced into bottom.
