Description
Technical field
The invention belongs to technical field of crane equipment, more particularly to a kind of self-locking crane suspension hook.
Background technique
Suspension hook is widely used in various loader and porter's works as one of the key components and parts in lifting appliance.Due to
The service life of torsional spring is limited in ordinary lifting hook self structure, and torsional spring is easily damaged, and is easily protected from environmental, so that insurance
Card cannot seal suspension hook well, meanwhile, suspension hook itself is designed without mousing-hook, and suspender belt takes off from suspension hook when be easy to causeing lifting
It falls.
Currently, the external device for having producer to use anti-locking hook, the step of this not only increases lifting, reduce work
Efficiency, and the cost of the external device production or purchase of anti-locking hook is increased, add the financial burden of enterprise.
Summary of the invention
The purpose of the present invention is to provide a kind of self-locking crane suspension hooks, by two self-locking arms to the suspension hook after lifting
It carries out self-locking, while secondary lock is carried out to the suspension hook opening after lifting with being hingedly rotatably assorted for hanging part is played by hook body
It is fixed, it solves existing suspension hook itself and is designed without mousing-hook, the problem of suspender belt falls off from suspension hook when be easy to causeing lifting.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions：
The present invention is a kind of self-locking crane suspension hook, including hook body, and the top of the hook body, which rotates, to be connected
It is connected to hanging part together；
The hook body includes a U-shaped hook bottom；It is equipped in the opposite two inside hook bodies of the U-shaped hook bottom
One conduit, the conduit is interior to be equipped with a rotary column；A self-locking arm is hinged with by rotary column in the conduit；The self-locking arm and rotary column
Hinged place be equipped with a torque spring, and the torque spring in the raw when self-locking arm top side be tightly attached to conduit
Bottom side；The interior bottom side of the U-shaped hook bottom has an arcwall face；
The top of the hook body is equipped with an articulated joint, and the articulated joint is equipped with a hinge hole；
Described hanging part includes a sunpender；The sunpender is a fold-type structure；The outside of the sunpender bending part be equipped with
The free bearing that articulated joint matches.
Further, the self-locking arm is a fold-type bar；The angle of the fold-type bar is 120 ° -150 °；The fold-type bar
Bending part be equipped with hinged through-hole is matched with rotary column.
Further, the opening direction of described two self-locking arms is opposite.
Further, the top of the sunpender offers fixed lifting hole(eyelet).
Further, the curved surface direction of the arcwall face is adapted with two self-locking arms along the rotation path of rotary column；It is logical
The design for crossing arcwall face avoids the rope being hung in hook body or rod piece from being detached from self-locking arm when sinking to hook body bottom,
When that need to take out rope or rod piece, self-locking arm generates barrier effect to taking-up.
Further, when being linked with rope or rod piece in hook body, the two self-locking arm stress are pushed, described self-locking
Arm is rotated along rotary column, is overlapped so that the top of two self-locking arms approaches, to reach self-locking effect；When being hung on suspension hook
When intrinsic rope or rod piece remove, two self-locking arms are by the elastic acting force of torque spring, and the self-locking arm is along rotary column
Rotation restores nature, and rope or rod piece are hung in hook body again convenient for subsequent.
Further, when hook body is lifted by crane, hook body is rotatably assorted by articulated joint and the hinged of free bearing,
One end of sunpender is supported and is ridden on hook body bill, to realize secondary sealed, effectively prevent the rope being hung in hook body
Rope or the improper of rod piece fall off.
The invention has the advantages that：
1, the present invention carries out the suspension hook after lifting by two self-locking arms self-locking, while by hook body and playing hanging part
It is hingedly rotatably assorted and secondary locking is carried out to the suspension hook opening after lifting, solve existing suspension hook itself and designed without mousing-hook,
The problem of suspender belt falls off from suspension hook when be easy to causeing lifting.
2, self-locking Suspension hook structure of the invention is simple, easy to use, highly-safe, guarantees that suspender belt does not fall out suspension hook.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
