Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

As shown in fig. 1 and 2; the utility model provides an inserted lift scaffold falls and detects automatic unhooking device, includes unhooking board 1, unhooking pendulum block 2, connects pendulum rod 3, buckle 4, and unhooking board 1 is as this unhooking device's the main part that bears, and unhooking board 1 is that the cutting of monoblock steel sheet forms, and the upper end of unhooking board 1 is provided with lifting eye, the lower extreme is provided with coupler body 1.1.

The waist between the connecting swing rod 3 and the unhooking plate 1 is hinged, the unhooking swing block 2 is hinged at the tail end of a hook body 1.1 of the unhooking plate 1, the buckle 4 is hinged at one end of the connecting swing rod 3, which is far away from the unhooking swing block 2, one end of the connecting swing rod 3 is meshed with or separated from the unhooking swing block 2, and the buckle 4 is meshed with or separated from the unhooking plate 1.

Specifically, the connecting swing rod 3 comprises two steel bars 3.1 and an L-shaped steel block 3.2, the buckle 4 is hinged between the two steel bars 3.1, the unhooking plate 1 is clamped between the two steel bars 3.1 and is hinged with the two steel bars, the L-shaped steel block 3.2 is welded at one end, close to the unhooking swing block 2, of each steel bar 3.1, and an open slot 3.3 for clamping the unhooking swing block 2 is reserved between the L-shaped steel block 3.2 and the end face of each steel bar 3.1; the unhooking swinging block 2 comprises two steel plates 2.1 and a clamping block 2.2, the two steel plates 2.1 clamp the tail end of the hook body 1.1 in the middle and are hinged with the hook body 1.1, the clamping block 2.2 is fixed between the two steel plates 2.1, and the clamping block 2.2 is provided with a locking tooth 2.3 which can extend into the open slot 3.3.

The tip of the hook body of the unhooking plate 1 forms a downward slope, and a steel wire rope for hanging the scaffold naturally slides down. Unhook pendulum block 2 with be connected the fender arm as coupler body 1.1 after 3 interlocks of pendulum rod, buckle 4 is the Z shape, buckle 4 includes, lower pole setting and horizontal pole 4.3, it has boss 1.2 to stretch out in the buckle side on the unhook board, boss 1.2 is last to have open-topped lockhole 1.3, lower pole setting 4.1 stretches into in the lockhole 1.3, the side can respectively with the preceding back wall butt of lockhole 1.3 around lower pole setting 4.1, buckle 4 and the articulated shaft of being connected pendulum rod 3 are located horizontal pole 4.3 and the angle of being connected of last pole setting 4.2, open on the top of last pole setting 4.2 has stay cord connecting hole 4.4, stay cord 5 is tied in stay cord connecting hole 4.4.

The locking teeth 2.3 are arc-shaped, the arc backs to the unhooking plate 1, and the friction force between the locking teeth 2.3 of the arc-shaped structures and the front of the open grooves 3.3 is increased.

The utility model discloses a unhook device is for relying on unhook pendulum mass 2 self gravity and heavy object extrusion, realizes automatic unhook through breaking away from and connecting pendulum rod 3. When the working principle is in a non-working state, the unhooking swing block 2, the connecting swing rod 3, the buckle 4 and the unhooking plate 1 are in a blocking state, so that the unhooking swing block is always in the non-working state shown in the figure 1. When the hook is not in working state, the lock tooth 2.3 is clamped in the open slot 3.3, the unhooking swing block 2 generates a tendency of anticlockwise rotation under self gravity, then the lock tooth 2.3 extrudes the slot wall of the open slot 3.3, the friction force between the open slot 3.3 and the lock tooth 2.3 limits the lock tooth 2.3 to be separated from the open slot 3.3, and the friction force is increased along with the increase of the load on the unhooking swing block 2. When the lock tooth 2.3 is to be separated from the open slot 3.3, the connecting swing rod 3 must rotate clockwise to release the constraint of the lock tooth 2.3. However, the rotation of the connecting swing rod 3 is limited by the buckle 4, when the buckle 4 is clamped in the lock hole 1.3, the right and downward force (depending on the direction of the drawing) is applied to the buckle 4 when the connecting swing rod 3 rotates, at this time, the lower vertical rod 4.1 is in the lock hole 1.3 and is abutted against the front and rear walls of the lock hole 1.3, the lower vertical rod 4.1 cannot be separated from the lock hole 1.3, and the rotation of the connecting swing rod 3 is prevented. In other words, to open the unhooking swing block 2 to unhook the scaffold, the buckle 4 must be pulled out from the lock hole 1.3 through the pull rope 5 to form a double-safety structure.

Through an external force pulling stay cord 5 during operating condition, buckle 4 rotates, and lower pole setting 4.1 is deviate from lockhole 1.3, continues exerting oneself, connects pendulum rod 3 clockwise rotation certain angle under the external force effect, and then removes the restriction to unhook pendulum block 2, and unhook pendulum block 2 relies on self gravity to break away from and connects pendulum rod 3 for the wire rope of connection drops on the coupler body 1.1, thereby realizes detecting the effect that whether scaffold falling device accords with the quality requirement.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
