Description
Technical field
The utility model relates to lift by crane equipment technology field more particularly to a kind of boom hoisting.
Background technique
When hydraulic steel gate is lifted by crane or put down, headstock gear can not be certainly when mainly operating whole process by headstock gear, but lifting by crane
It is dynamic to be connected with the hanging axis on gate, and after putting down gate, headstock gear can not be also detached from gate automatically.The general position of hydraulic steel gate
In under water or in deeper gate slot, de-, the hook of manual operation headstock gear are difficult to realize.Auto clawing beam is a kind of common use
In the ancillary equipment for lifting by crane or putting down hydraulic steel gate, unhook, the hook operation of gate can be automatically performed.Auto clawing beam at present
It is divided into boom hoisting and two kinds of hydraulic automatic grabbing beam, boom hoisting has Weight type, hanging-ring type, de- extension a variety of shapes such as formula freely again
Formula, wherein Weight type machinery grasping beam due to weight weight it is larger, manual operation is got up relatively elaborate；Hanging-ring type machinery grasping beam relies on
Spring detent breaks off relations, and reliability is not high, and the capacity of hanging ring is little, in addition, spring arrangement is easy to damage, and complicated ring under water
In border, failure rate is very high；De- formula machinery grasping beam freely of hanging is only applicable to Gate since hanging body size is larger；It is hydraulic automatic
Grasping beam high reliablity, but since it contains hydraulic power unit, and need plant-grid connection and carry out waterproof setting, price is more expensive,
It is mainly used for large and medium-sized operating gate.
Utility model content
The technical problems to be solved in the utility model is simple, the cost that overcomes the deficiencies of the prior art and provide a kind of structure
Cheap, high reliablity is less prone to stuck or the case where cannot break off relations, and can be improved lifting or that puts down working efficiency plays lifting
It sets.
In order to solve the above technical problems, the utility model uses following technical scheme:
A kind of boom hoisting, including liftable mounting portion are hinged with suspension hook and lock, the lock on the mounting portion
Positioned at the top of the suspension hook, the suspension hook and lock can be rotated around hinge joint in perpendicular, and the lock is equipped with
First clamping part, the upper end of the suspension hook are equipped with the second clamping part cooperated with first clamping part, and the lock is rotatable
Off-position to the first clamping part far from the suspension hook, or rotate to the first clamping part close to the working position of the suspension hook
It sets, when the lock is located at operating position, the suspension hook, which can be rotated towards the lock to first clamping part and second, to be blocked
Buckle fastens.
After transferring suspended object, it can be prevented from restoring plumbness, promoted at this time by the suspension hook for clasping rotation
Boom hoisting can break off relations, and complete the process for putting down suspended object.
As a further improvement of the above technical scheme:
The suspension hook includes articulated section, and the hook part positioned at articulated section lower end, and the hook part, which has, accommodates hanging axis
Groove, the suspension hook has that hanging axis is located at hook status in groove and hanging axis is disengaged to unhook state above groove, when
When the suspension hook is in unhook state, the lock is located at operating position, and hanging axis described in the suspension hook uphill process cannot
Into in the groove.
The suspension hook can be stopped to rotate around hinge joint to the hanging axis to enter institute during decline by the hanging axis
After stating in groove to realize that hook status, hanging axis enter in groove, suspension hook restores plumbness, suspension hook under the effect of gravity
Hook hanging axis；The suspension hook in hook status, the suspension hook continue decline during can by the hanging axis stop to around
Hinge joint is rotated to realize that hook status is switched to unhook state.
The bottom of the hook part has for abutting with the hanging axis and the suspension hook being guided to rotate around hinge joint with reality
First guide surface of existing hook status.
First guide surface is the convex globoidal that bill is extended to by the bottom face of the hook part, and convex globoidal connects with hanging axis
When touching, suspension hook is enable to rotate around hinge joint, so that hanging axis can be directed into groove to realize hook.
The bent hook part has in the top of the groove for abutting with the hanging axis and guiding the suspension hook around hinge
Contact rotates the second guide surface to realize the switching of hook status to unhook state.
Second guide surface be the articulated section lateral surface lower part ipsilateral with the groove be angled inwardly into it is described
It is connected at the top of groove medial surface and is formed by inclined-plane.When hanging axis and the contact of incline plane, suspension hook can be rotated around hinge joint, to latch
Clasp suspension hook.
Second clamping part of the downward concave shape stepped in the one end of the suspension hook upper surface far from the lock, the lock
Button bit is when off-position, first buckle of the lock upper surface close to the downward concave shape stepped in one end of suspension hook
Portion.
To adapt to the lifting of hydraulic steel gate or putting down, one of the structure as submarine mechanical auto clawing beam, the installation
The crossbeam that portion is arranged horizontally, there are two the suspension hook is set, two suspension hooks are arranged along the length direction interval of the crossbeam；
The lock is correspondingly provided with two, and the lock and the groove for corresponding to suspension hook are respectively positioned on the same side of the articulated section of corresponding suspension hook.
To adapt to the lifting of hydraulic steel gate or putting down, two of the structure as submarine mechanical auto clawing beam, the installation
The crossbeam that portion is arranged horizontally, there are two the suspension hook is set, two suspension hooks are arranged along the length direction interval of the crossbeam；
