Description
Technical field
The present invention relates to field, especially a kind of truss-like ocean platform crane luffing stop gear.
Background technology
In prior art, the luffing upper limit of truss-like ocean platform crane, normally used is single hydraulic stop; Truss-like ocean platform crane is in certain time limit of having worked, luffing hydraulic pressure upper limit there will be malfunctioning phenomenon, if operating personal is not found the malfunctioning situation of luffing hydraulic pressure upper limit in time, and proceed the words of luffing action, can cause whole arm to recede, fall because conducting oneself with dignity, cause great safety misadventure, serious threat boats and ships and personnel's safety.
Summary of the invention
The applicant is for the shortcoming in above-mentioned existing production technology, a kind of truss-like ocean platform crane luffing stop gear rational in infrastructure is provided, thereby is limited under malfunctioning state on luffing hydraulic pressure, prevent the phenomenon that arm tilts to fall, improved functional reliability, safety factor is high.
The technical solution adopted in the present invention is as follows:
A truss-like ocean platform crane luffing stop gear, comprises A shape frame and arm, and level connection joint limited location bar between described A shape frame and arm is connected with hound between described position-limited lever bottom and A shape frame, the structure of described position-limited lever is: one end of described position-limited lever is connected with the eye plate of A shape frame by the first hinging pin shaft, the other end of described position-limited lever is inserted with buffering socket, the structure of described buffering socket is: be positioned at position-limited lever and be provided with baffle plate, on described baffle plate, by bolt, be horizontally installed with buffing pad, buffering bearing pin is installed in described buffing pad, on described buffing pad, be provided with step, the First terrace of buffing pad is fastening by the end face of circular nut and position-limited lever, be positioned on the buffering bearing pin of second step face of buffing pad yielding rubber is installed, the outer end of described buffering bearing pin connects buffer head, the structure of described hound is: one end of described hound is connected with A shape frame by the second hinging pin shaft, and the described hound other end is provided with coupling link, and described coupling link is connected with the hinged eye plate of position-limited lever bottom.
Further improvement as technique scheme:
On the described second step face that is positioned at buffing pad, lubricating cup is also installed.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, reasonable, easy for installation, by the effect of mounting limit bar and hound between A shape frame and arm, effectively solve truss-like ocean platform crane at the certain time limit of work, luffing hydraulic pressure upper limit suddenly in malfunctioning situation operating personal do not find in time, proceed luffing on arm and the problem of the serious accident that the arm that causes recedes, falls; The present invention is in the situation that luffing hydraulic pressure upper limit is suddenly malfunctioning, and anti-dumping is spacing in addition can normally work, and the arm causing to guarantee arm can not overstep the extreme limit upper change angle recedes and falls, and reliability of service is good, safe.
