The present invention relates to a kind of case top safe fall-proof locking bar, comprise hand driving lever, opening and closing dead bolt, safety strap suspension hook, described hand driving lever and opening and closing dead bolt are fixedly connected, and this opening and closing dead bolt is fixed with open locking indicator stem; Described hand driving lever is connected with lockhole Connection Block, this lockhole Connection Block is right against the top of opening and closing dead bolt, and is provided with the safety strap suspension hook for hanging safety belt on this lockhole Connection Block; Described open locking indicator stem, opening and closing dead bolt, the triangular position of hand driving lever are located along the same line, and connect into as a whole.The connection dimension of described lockhole Connection Block coordinates with container lock hole dimension, and on described lockhole Connection Block, be provided with the inspection door being convenient to observe open locking indicator stem state.Beneficial effect of the present invention is: safe fall-proof locking bar significantly can improve the safety of tying up work and facing limit operation on case top after using, and eliminates potential potential safety hazard.
Description
Technical field
The invention belongs to the technical field of mechanical automation of container terminal handling technologies and equipment, particularly relate to a kind of case top safe fall-proof locking bar.
Background technology
Need to tie up solution to the freight container on boats and ships before container terminal loading and unloading operation to tie up, need to tie up colligation to the freight container on boats and ships after the end of job.Tie up work to be responsible for solution and to tie up and colligation work, tie up work because the complexity of operating environment, belong to the industry of high-risk.Tie up the case top that work often will walk in freight container, and case top is due to the existence of superelevation case, the therefore low unfairness of height, easily trips.Particularly face when case top, limit solution is tied up more dangerous at freight container, tying up work needs to go to most edge, and case top does not have can the place of hooking safety strap.High falling ties up the maximum danger of work, and consequence is hardly imaginable.There is hidden danger in the safety precaution in this respect of other container wharfs, often has the situation generation of tying up work and falling too.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide one to tie up work can to hang up properly safety strap more easily on case top, can be very safe in the operation of case top, constructed the case top safe fall-proof locking bar in the life defence line of tying up work together.
The object of the invention is to have come by following technical solution, it comprises hand driving lever, opening and closing dead bolt, safety strap suspension hook, and described hand driving lever and opening and closing dead bolt are fixedly connected, and this opening and closing dead bolt is fixed with open locking indicator stem; Described hand driving lever is connected with lockhole Connection Block, this lockhole Connection Block is right against the top of opening and closing dead bolt, and is provided with the safety strap suspension hook for hanging safety belt on this lockhole Connection Block; Described open locking indicator stem, opening and closing dead bolt, the triangular position of hand driving lever are located along the same line, and connect into as a whole.
As preferably, the connection dimension of described lockhole Connection Block coordinates with container lock hole dimension, and on described lockhole Connection Block, be provided with the inspection door being convenient to observe open locking indicator stem state.
Beneficial effect of the present invention is: safe fall-proof locking bar significantly can improve the safety of tying up work and facing limit operation on case top after using, and eliminates potential potential safety hazard.

Label in accompanying drawing is respectively: 1, hand driving lever; 2, safety strap suspension hook; 3, lockhole Connection Block; 4, opening and closing dead bolt; 5, inspection door; 6, open locking indicator stem.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed introduction is done to the present invention: as shown in accompanying drawing 1,2, the present invention includes hand driving lever 1, opening and closing dead bolt 4, safety strap suspension hook 2, described hand driving lever 1 is fixedly connected with opening and closing dead bolt 4, and this opening and closing dead bolt 4 is fixed with open locking indicator stem 6; Described hand driving lever 1 is connected with lockhole Connection Block 3, and this lockhole Connection Block 3 is right against the top of opening and closing dead bolt 4, and is provided with the safety strap suspension hook 2 for hanging safety belt on this lockhole Connection Block 3.The connection dimension of described lockhole Connection Block 3 coordinates with container lock hole dimension, can enter lockhole and not too large very smoothly; And on described lockhole Connection Block 3, be provided with the inspection door 5 being convenient to observe open locking indicator stem 6 state.Described open locking indicator stem 6, opening and closing dead bolt 4, the triangular position of hand driving lever 1 are located along the same line, and connect into as a whole.Hand driving lever 1 action can drive open locking indicator stem 6 and opening and closing dead bolt 4 to rotate, thus reaches the action of pinning freight container lock pin.
Principle of work of the present invention is: as accompanying drawing 3, shown in 4, tie up work when the operation of case top, as long as safety strap is hung on the safety strap suspension hook 2 of safe fall-proof locking bar, then safe fall-proof locking bar is placed on the freight container lockhole near operating area by lockhole Connection Block 3, the position leaving nearly 45 degree of lock position is pushed with hand driving lever 1, this position is also equipped with limit pin and self-locking device, cannot move again after making it arrive locked position of coupler, and self-locking device can allow him keep blocking, until hand driving lever 1 action, the state of open locking can be seen at inspection door 5, the action situation of opening and closing dead bolt 4 can also be seen, even if hand driving lever 1 and opening and closing dead bolt 4 are connected with problem like this, also clearly can see at inspection door 5, so just can avoid the generation of the fault caused by connectivity problem.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
