Abstract
The utility model relates to a come-off preventing hoisting clamp capable of installing and detaching quickly. The come-off preventing hoisting clamp comprises a body, a hinge, and a clamping hinge. The hinge and the clamping hinge are hinged to one side face of the body respectively through a hinge shaft and a clamping hinge shaft. The hinge and the clamping hinge are correspondingly in a locking clamped state or in a loose separation mode. The two ends of the body are respectively provided with a downward-inclined hoisting opening. Parts, on the lower portions of the hoisting openings, of the body are movably hinged to lower portions of baffle ring bodies. Parts, on upper portions of the hoisting openings, of the body are provided with body pin holes. The upper portion of each baffle ring body is provided with a lifting ring pin which is in a non-horizontal penetrated connecting state with one body pin hole. Baffle ring bodies which are capable of movably rotating and limiting the hoisting openings after being connected with clamping ring body locks are arranged on the hoisting openings at the two ends of the hoisting clamp body. The come-off preventing hoisting clamp capable of installing and detaching quickly can install a hoisting clamp with a hanging ring quickly in a come-off preventing mode, is simple and compact in structure, convenient to operate, capable of installing and detaching the hanging ring quickly and preventing the hanging ring from coming off a hanging lug, and high in utilization safety.
Description
Technical field
The utility model relates to a kind of elevator, be specifically a kind ofly can load and unload fast suspension ring, prevent suspension ring from the hanger quick loading and unloading drop-proof elevator of throwing off, can be widely used in petroleum drilling operation.
Background technology
Existing forging elevator generally adopts plug-in type safety pin or magnetic security pin, plug together the restriction suspension ring by safety pin, the suspension ring clamping is simple to operate, rapid, but safety pin grafting reliability is relatively poor, the loss of in use easily becoming flexible, come off, or be wound around by rope, easily cause suspension ring to get loose, there is the falling object risk, the great person and equipment breakdown easily occur when particularly monaural lifts by crane.And the foundry goods elevator generally adopts the form of baffle ring, baffle ring is with fixedly limiting suspension ring on elevator, fixedly reliability is high by bolt-locking for baffle ring, non-loosening, potential safety hazard comes off, but bolt loading and unloading is wasted time and energy, particularly in the situation that frequent rising unloaded brill, operating personnel's labour intensity is high, inefficiency.
Summary of the invention
For the deficiency that operating characteristics in prior art and security performance can't be taken into account, it is a kind of simple in structure, compact that the utility model provides, and simple operation, safety can be fast, the quick loading and unloading drop-proof elevator of safety loading lifting.
The technical solution adopted in the utility model is: a kind of quick loading and unloading drop-proof elevator, comprise main body, loose-leaf and card page, loose-leaf and card page are movably hinged on main body one side through hinge axis, hinge axis respectively, loose-leaf and card page correspondence are the locking obvolvent or unclamp released state, lifting mouth under the two ends of main body are equipped with and are tilted to, it is characterized in that: be movably hinged a baffle ring body bottom on the main body of described lifting mouthful bottom, the main body on lifting mouthful top is provided with a body pin, and baffle ring body top is provided with the drop handle pin that is non-horizontal cross-under state with body pin.
Further, described drop handle pin is arranged at baffle ring body top through baffle ring body Compress Spring, and the drop handle pin is provided with drop handle.
Further, described loose-leaf is provided with the loose-leaf pin-and-hole outside main body one side, and on described card page, through card page Compress Spring cross-under one lock pin, the connecting rod on the lock pin one hinged loose-leaf of end, the lock pin other end are corresponding grafting with the loose-leaf pin-and-hole and lock or disengaged condition.
Further, described body pin axially and hinge axis axially not parallel.
Further, described loose-leaf is provided with handle.
Further, described body pin is axially with vertical with lifting mouthful incline direction.
compared with prior art, the utility model has the advantages that: the hinged baffle ring body of lifting mouth end at elevator body two ends, the baffle ring body is around lifting mouthful rotation, difference linking springs cover on the baffle ring body, baffle ring body Compress Spring and drop handle pin, the drop handle pin can stretch under the effect of external force and spring force freely by drop handle, in the time of in the drop handle pin inserts body pin, thereby play the effect of locking lifting mouthful interior suspension ring, the interlocking simple operation, can satisfy loading and unloading lifting requirement fast, and the baffle ring body is fixed on main body, drop handle pin and lifting mouthful perpendicular direction, it is stable that suspension ring are locked in lifting mouthful interior locking, can be effectively locking, slip-off preventing, use safety, when the drop handle pin stretched out outside body pin, the outside Unscrew of baffle ring body made the lifting mouth without block resistance, and the baffle ring body of open mode can effectively be reminded the operator, and the baffle ring body does not insert firmly, and avoids the driller blindly to lift by crane, and improves usage safety performance.
The baffle ring body that the utility model lifts by crane at the two ends of elevator body and sets up movable rotation on mouth, connects elevator body lock restriction lifting mouth through the drop handle pin, satisfy the quick anticreep loading and unloading of elevator and suspension ring, it is simple in structure, compact, simple operation, can load and unload fast suspension ring, prevent suspension ring from hanger throw off, usage safety performance is high.
