Description
Technical field
This utility model is related to a kind of preventing wire rope from falling hook device of crane.
Background technology
A mousing-hook baffle plate, the baffle arrangement of this structure are connected with by torsion spring all typically on the suspension hook of conventional hoist
Simply, and serve really to a certain extent mousing-hook effect, but due to this baffle plate when hanging or remove goods needs
Manpower moves and carries out spacing, using inconvenience, is rarely applied to large-scale crane hook, this work to goliath at present
Bring certain potential safety hazard.
Utility model content
This utility model aims to overcome that above-mentioned the deficiencies in the prior art, there is provided a kind of to easily facilitate the steel wire rope for using
Anti-hook releasing device.
The technical solution of the utility model is：A kind of preventing wire rope from falling hook device, including being movably connected on suspension hook opening
On baffle plate, the baffle plate is additionally provided with ratchet wheel positioning mechanism with the junction of the suspension hook, and the ratchet wheel positioning mechanism includes
One locating shaft, the ratchet being connected on first locating shaft, the second locating shaft and it is connected on second locating shaft
Ratchet, the baffle plate are rotatably connected on the suspension hook by first locating shaft, first locating shaft and the suspension hook
Between be additionally provided with the first torsion spring, be additionally provided with the second torsion spring between second locating shaft and the baffle plate, the ratchet with it is described
Ratchet is mutually engaged.
Alternatively, the ratchet and the ratchet have a set of or two sets.
Further, second locating shaft is arranged at the top of first locating shaft.
Further, spanner is additionally provided with the ratchet.
Further, a support plate, first locating shaft and second locating shaft is also respectively provided with the baffle plate both sides
Through the support plate.
The beneficial effects of the utility model are：During utility model works, manpower moves baffle plate, and baffle plate is in ratchet localization machine
Can be positioned at any time at any angle under structure effect, it is more safe and reliable, prevent from crushing staff, and can be according to the thick of steel wire rope
Spend to set the angle that baffle plate time is broken, break on earth without one, save manpower；During reset, only need to pull spanner makes ratchet and ratchet
Separate, origin-location is returned in the first torsion spring effect lower baffle plate, it is convenient easy-to-use, it is adaptable to various large, medium and small cranes
Hook.
