Abstract
The utility model relates to a box top anti-drop safety locking rod which comprises a manual deflector rod, an opening-closing lock tongue and a safety belt lifting hook. The manual deflector rod is fixedly connected with the opening-closing lock tongue, and the opening-closing lock tongue is fixedly connected with an opening-closing indication rod. A lock hole connecting seat is connected onto the manual deflector rod and is rightly opposite to the upper portion of the opening-closing lock tongue, and the lock hole connecting seat is provided with the safety belt lifting hook for hanging a safety belt. The positions of the opening-closing indication rod, the opening-closing lock tongue and the manual deflector rod are located on the same straight line and connected to form a whole. The connecting size of the lock hole connecting seat is matched with the size of a container lock hole, and an observation hole for facilitating observation of a state of the opening-closing indication rod is formed in the lock hole connecting seat. The box top anti-drop safety locking rod has the advantages that the safety of box top edge-near operation performed by bundling workers can be remarkably improved after the anti-drop safety locking rod is used, and potential safety hazard is eliminated.
Description
Technical field
The utility model belongs to the mechanical automation technical field of container terminal handling technologies and equipment, relates in particular to a kind of case top safe fall-proof locking bar.
Background technology
Before container terminal loading and unloading operation, need that the freight container on boats and ships is tied up to solution and tie up, after the end of job, need the freight container on boats and ships to tie up colligation.Tie up work and be responsible for solution and 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 pushes up the existence due to superelevation case, the therefore low unfairness of height, easily trips.Particularly face case top, limit solution at freight container more dangerous while tying up, tie up work and need to go to edge, case top does not have place that can hooking safety strap.High falling is the danger of tying up work maximum, and consequence is hardly imaginable.There is hidden danger in the safety precaution in this respect of other container wharfs, often has the situation that the work of tying up is fallen to occur too.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and can hang up properly more easily safety strap on case top and provide one to tie up work, 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 together work.
The purpose of this utility model completes by following technical solution, and it comprises hand driving lever, opens and closes dead bolt, safety strap suspension hook, and described hand driving lever is fixedly connected with opening and closing dead bolt, on this switching dead bolt, is fixed with open locking indicator stem; On described hand driving lever, be connected with lockhole Connection Block, this lockhole Connection Block is right against the top that opens and closes dead bolt, and on this lockhole Connection Block, is provided with the safety strap suspension hook for hanging safety belt; Described open locking indicator stem, switching 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 is provided with the inspection door of being convenient to observe open locking indicator stem state on described lockhole Connection Block.
The beneficial effects of the utility model are: safe fall-proof locking bar can significantly improve after using ties up work is faced limit operation safety on case top, has eliminated potential potential safety hazard.

Label in accompanying drawing is respectively: 1, hand driving lever; 2, safety strap suspension hook; 3, lockhole Connection Block; 4, open and close dead bolt; 5, inspection door; 6, open locking indicator stem.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is done to detailed introduction: as shown in accompanying drawing 1,2, the utility model comprises hand driving lever 1, opens and closes dead bolt 4, safety strap suspension hook 2, described hand driving lever 1 is fixedly connected with opening and closing dead bolt 4, on this switching dead bolt 4, is fixed with open locking indicator stem 6; On described hand driving lever 1, be connected with lockhole Connection Block 3, this lockhole Connection Block 3 is right against the top that opens and closes dead bolt 4, and on this lockhole Connection Block 3, is provided with the safety strap suspension hook 2 for hanging safety belt.The connection dimension of described lockhole Connection Block 3 coordinates with container lock hole dimension, can enter very smoothly lockhole and not too large; And on described lockhole Connection Block 3, be provided with the inspection door 5 of being convenient to observe open locking indicator stem 6 states.Described open locking indicator stem 6, switching 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 open and close dead bolt 4 and rotate, thereby reaches the action of pinning freight container lock pin.
Principle of work of the present utility model is: as accompanying drawing 3, shown in 4, tie up work in the time of 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 near freight container lockhole operating area by lockhole Connection Block 3, push the position of leaving nearly 45 degree of lock position with hand driving lever 1, this position has also been equipped with limit pin and self-locking device, after making it arrive locked position of coupler, cannot move again, and self-locking device can allow him keep blocking, until hand driving lever 1 moves, the state of open locking can be seen at inspection door 5, can also see the action situation that opens and closes dead bolt 4, even if hand driving lever 1 and switching dead bolt 4 are connected with problem like this, also can clearly see at inspection door 5, so just can avoid the generation of the fault being caused by connectivity problem.
The utility model is not limited to above-mentioned embodiment; no matter do any variation in its shape or material formation; every employing structure design provided by the utility model, is all a kind of distortion of the present utility model, all should think within the utility model protection domain.
