Locking the rope pulley protective cover:

in the lifting process of the rope pulley protective cover (8), the compression spring (2) is compressed against the inclined plane of the lock plunger (1) to perform shrinkage action, after the rope pulley protective cover (8) is lifted to be positioned, the lock plunger (1) ejects and locks the rope pulley protective cover (8), the lock plunger (1) ejects the inclined plane of the lock plunger (3) in the process, the lock plunger (3) overcomes the acting force rotation of the torsion spring (4), after the lock plunger (1) ejects in place, the lock plunger (3) is blocked in the groove of the lock plunger (1), and the lock plunger (1) is locked by the lock plunger (3), so that the lock plunger (1) cannot stretch out and draw back.

The beneficial effects are that:

in order to overcome the technical defects of the prior art in the technical background, the quick self-locking mechanism of the rope pulley protective cover is disclosed, the mechanism can quickly lock the rope pulley protective cover, and meanwhile, a lock plunger for locking the rope pulley protective cover can be further locked, so that the danger of unlocking caused by false triggering is avoided.

In order to solve the technical problems, the utility model adopts the following technical scheme:

the rope pulley protective cover can stretch and retract against the lock plunger, and the lock plunger can automatically lock the rope pulley protective cover after the rope pulley protective cover is installed in place;

after the protective cover of the lock bolt lock rope wheel is in place, the lock hook can lock the lock bolt together, so that the lock bolt can be quickly locked.

The mechanism of the utility model has the following characteristics:

1. the lock bolt can automatically lock the rope pulley protective cover in the process of lifting the rope pulley protective cover;

2. after the protective cover of the lock bolt lock rope wheel is in place, the lock hook can lock the lock bolt together, so that the lock bolt can be quickly locked.
