Abstract
The utility model relates to the field of engineering machinery, in particular to a device for preventing steel wire collision of a drilling machine A-shaped tower, which comprises tower arms forming the A-shaped tower, pulley blocks arranged at the joints of the tower arms at two sides, a winch and a drill rod positioned below the A-shaped tower, wherein the winch scroll, the drill rod and the pulley are sequentially connected through a steel wire rope, a bracket is fixedly arranged at one side of the A-shaped tower arm facing to the winch, a rolling shaft lever is arranged at one side of the bracket away from the tower arms, the steel wire rope is lapped on the outer circumferential surface of the shaft lever of the rolling shaft lever in a sliding way, compared with the prior art, the bracket is arranged between the drilling machine A-shaped tower arms, so that the steel wire rope led out from the pulley blocks must pass through the outer circumferential surface of the rolling shaft lever and then be connected with the winch, thereby limiting the movement of the, the structure is simple to manufacture, safe to use and reliable in performance.
Description
Technical Field
The utility model relates to an engineering machine tool field specifically indicates a steel wire collision device is prevented to rig A type tower.
Background
The fixed pulley is connected to one end of the top of a tower, one end of a steel wire rope penetrating through the fixed pulley is directly connected with a drill rod below the fixed pulley, the other end of the steel wire rope is directly connected with a rotating shaft of a winch, and the steel wire rope swings in the A-type tower of the drilling machine under the action of inertia of the steel wire rope when the winch works, so that the danger of interference and collision of the steel wire rope and the tower arm structure of the A-type tower of the drilling machine easily exists, and the use safety of the drilling machine is influenced.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a rig A type tower prevents steel wire collision device, includes the tower arm of constituteing A type tower, sets up in the assembly pulley of both sides tower arm junction and is located hoist engine and the drilling rod of A type tower below, connect gradually through wire rope between hoist engine spool, drilling rod and the pulley, A type tower arm is fixed towards hoist engine one side and is equipped with the support, the support is kept away from tower arm one side and is equipped with the roll axostylus axostyle, wire rope slidable overlap joint in the axostylus axostyle outer peripheral face of roll axostylus axost.
As an improvement, a plurality of groups of cross beams are uniformly arranged between the steel longitudinal beams forming the tower arm along the axis direction.
As an improvement, the pulley block consists of a bottom plate and two pulleys arranged above the bottom plate.
After the structure more than adopting, the utility model has the advantages of as follows:
compared with the prior art, the support is arranged between the A-shaped tower arms of the drilling machine, so that the steel wire rope led out from the pulley block is connected with the winch after passing through the peripheral surface of the rolling shaft rod, the movement of the steel wire rope is limited, and the problems of interference and collision of a balance weight and a mechanism are solved.
