Technical field
The utility model relates to a kind of arm steering hardware of hoisting crane, particularly relates to the arm steering hardware of hoisting crane on a kind of sailing course drill.
Background technology
Sailing course drill is widely used in the blast hole Drilling of underwater engineering reefs such as rivers navigation channel, coastal waterway and port and pier construction.In the work progress of sailing course drill boring, in order to reach the requirement of drilling depth, usually need to carry out work such as repetition connecting and disconnecting drill rod and sleeve pipe, because of drilling rod with sleeve pipe is all long and heavy, so generally all dispose lifting and other the auxiliary hoisting operation that two hoisting cranes carry out drilling rod and sleeve pipe on the sailing course drill.The arm of two hoisting cranes is installed on the drilling cramp top, and aspect ratio is higher, requires steel rope to be difficult for twining and jumping out, and arm can rotate, and enlarges scope of work, and lifting is convenient.
The utility model content
Technical problem to be solved in the utility model provides a kind of steel rope and be difficult for to twine and jump out, and arm can rotate, and scope of work is big, lifts the arm steering hardware of hoisting crane on the sailing course drill easily.
In order to solve the problems of the technologies described above, the arm steering hardware of hoisting crane on the sailing course drill that the utility model provides, axial vertical fixing is provided with two center shafts on the arm seat, the axial centre of each described center shaft has a through hole, on each described center shaft, be rotatablely equipped with an arm by plain bearing and pressing plate, the other end away from described center shaft on the described arm is provided with first pulley, close on described center shaft on the described arm and be provided with second pulley, close on each described center shaft on the described arm seat and be provided with the 3rd pulley, the edge that closes on drilling cramp on the described arm seat is provided with the 4th pulley that cooperates with described the 3rd pulley, steel rope is through described the 4th pulley, the 3rd pulley, through hole, on second pulley and first pulley, retaining rope bolt all is equipped with on each leading sheave next door.
Each described arm is provided with the alemite that is communicated with described plain bearing.
The arm steering hardware of hoisting crane on the sailing course drill of employing technique scheme, the arm seat is installed on the top of sailing course drill drilling cramp by bolt, the center shaft that arm rotates is weldingly fixed on the arm seat, in the middle of the center shaft through hole is arranged, and is convenient to steel rope and passes through in center shaft.Between center shaft and the arm plain bearing is installed, and alemite is installed, by injecting lubricating oil, arm can rotate like a cork around center shaft.Pressing plate is by being bolted on the center shaft, can prevent that arm from deviating from center shaft.The arm steering hardware is equipped with eight leading sheaves altogether, and retaining rope bolt all is equipped with on each leading sheave next door, can prevent that steel rope from jumping out pulley, makes steel rope be difficult for twining or blocking.
The utlity model has following tangible advantage: a through hole is arranged in the middle of (1), the design center axle, be convenient to steel rope and pass through, arm can easily turn to, slewing area is wide during operation.(2), the arm steering hardware is equipped with a plurality of leading sheaves, retaining rope bolt all is equipped with on each leading sheave next door, can prevent that steel rope from jumping out pulley, makes steel rope be difficult for twining or blocking.
In sum, the utility model is that a kind of steel rope be difficult for to twine and jumps out, and arm can rotate, and scope of work is big, lifts the arm steering hardware of hoisting crane on the sailing course drill easily.
