Example one

As shown in fig. 1, 2 and 6, the safety catch provided by the present embodiment includes: guide 100, lock member 200 and transmission member 300; the locking piece 200 is movably connected to the guide seat 100, and the locking piece 200 is provided with an anti-falling station and an unlocking station; at the anti-falling station, the locking piece 200 is used for abutting against the climbing frame 600 to prevent the climbing frame 600 from falling; at the unlocking station, the locking piece 200 is separated from the climbing frame 600; transmission member 300 is used for driving locking member 200 and removes to the unblock station from preventing weighing down the station.

Specifically, when the locking member 200 is located at the anti-falling station, the upper end surface of the locking member 200 abuts against the climbing frame 600, so that the gravity of the climbing frame 600 is borne by the locking member 200, and the climbing frame 600 is prevented from falling; transmission member 300 can drive locking piece 200 and move to the unblock station from preventing weighing down the station, and when locking piece 200 was located the unblock station, locking piece 200 separated with climbing frame 600, and climbing frame 600 can descend under the action of gravity, perhaps, climbing frame 600 rises under lifting and pulling the effect of jacking equipment, can realize from this climbing the regulation of frame 600 position height.

In some embodiments, the lock member 200 includes a locking tongue slidably coupled to the guide 100; the transmission element 300 is in transmission connection with the lock tongue, and the lock tongue can be driven to move telescopically relative to the guide seat 100 through manual operation of the transmission element 300, so that the locking piece 200 can move between an unlocking station and an anti-falling station. For example: the transmission member 300 is configured as a connecting rod, the connecting rod is connected with the lock tongue, and the manual push-pull connecting rod can drive the lock tongue to move telescopically relative to the guide seat 100; alternatively, the driving member 300 is configured as a gear, and the latch is provided with a rack gear, and the gear is engaged with the rack gear, so that the latch can be driven to move telescopically with respect to the guide 100 by rotating the gear.
