Manipulate valve body termination to be fixedly connected, another termination extends along manipulating valve driving lever direction, and the elongated end of described first connecting plate is fixed
It is connected with the U-shaped hook towards the second connecting plate direction bending, one end of described U-shaped hook is fixedly connected with the first connecting plate,
The other end has pin hole along U-shaped hook place face vertical direction insertion；The extended tip of described second connecting plate be fixed with
Manipulate the vertical sleeve pipe in valve driving lever place face, be installed with the rotating shaft that sleeve pipe is stretched out at two ends in described sleeve pipe, the two of described rotating shaft stretches out
End has through hole along rotating shaft radial direction, and the minimum range of described two through hole should ensure that more than the maximum gauge manipulating valve driving lever, described
It is installed with U-shaped deadlock lever, the opening two ends of described U-shaped deadlock lever are each passed through two through hole in rotating shaft, and described U-shaped closes in through hole
The U-shaped portion of locking bar is divided and is hooked in U-shaped hook, and described U-shaped is linked up with the pin hole of the other end and is inserted with split pin.Connecting plate is to whole
Its fixing supporting role of individual blocking device.First connecting plate elongated end is fixed with U-shaped hook, forms the lock of blocking device.The
Two connecting plate extended tips are fixed with sleeve pipe, are installed with rotating shaft in sleeve pipe, and rotating shaft is installed with U-shaped deadlock lever, make U-shaped deadlock lever and
Two connecting plates form articulated structure, and U-shaped deadlock lever can rotate around the axis.Two through hole minimum range is more than the maximum manipulating valve driving lever
It is ensured that the body of rod two ends of U-shaped deadlock lever are located at respectively and manipulate valve driving lever both sides, constraint manipulates valve driving lever and cannot dial to both sides diameter
Dynamic, play two-way malfunction protective effect.The U-shaped portion of U-shaped deadlock lever divide be hooked on U-shaped hook in, and with split pin U-shaped hook
Termination pin joint is so that U-shaped deadlock lever is limited in U-shaped hook.
Described U-shaped deadlock lever passes through the termination of through hole to side bending or to be installed with anticreep pin.U-shaped deadlock lever passes through through hole
One end bends or wears anticreep pin, and when preventing from rotating U-shaped deadlock lever, termination is deviate from by through hole.
This utility model has advantages below：1st, structure is simple, cheap for manufacturing cost；2nd, easy and simple to handle, extract or plug
Split pin, rotates U-shaped deadlock lever and can achieve the locking to hydraulically operated valve and unblock；3rd, U-shaped deadlock lever two body of rod position respectively
In manipulating valve driving lever both sides, two-way prevent from manipulating valve driving lever there is malfunction, safety coefficient is high.
