Abstract
The utility model provides a rig with function is prevented weighing down by drilling rod belongs to the technical field of rig, including the rig body, be equipped with two wire rope that are used for pulling the drilling rod when the drilling rod glides between rig slide afterbody and water just. Through install two wire rope additional between rig slide afterbody and water just for when constructing the big-angle drilling such as roof drainage water, play one when not having the plan and having a power failure rig pressure release back drilling rod gliding and pull the effect to the drilling rod, thereby avoid the drilling rod gliding to injure pedestrian and break the water just.
Description
Technical Field
The utility model belongs to the technical field of the rig, a rig with function is prevented weighing down by drilling rod is specifically disclosed.
Background
In the construction roof drainage water drilling engineering, when the inclination is more than 40 degrees, the pressure of the drilling machine is released because of unplanned power failure, the drill rod slides down due to the fact that the angle is large and gravity is increased and then exceeds friction force, and therefore the phenomenon of water and excrement breaking is caused, the production cost is greatly increased, the problem of support saving and consumption reduction is solved, and the hidden danger of injuring pedestrians due to the fact that the drill rod slides down is also existed.
SUMMERY OF THE UTILITY MODEL
The utility model discloses reforming transform current rig, obtaining a rig that has the drilling rod and prevent weighing down the function, when rig wide-angle drilling meets unplanned power failure rig pressure release, can effectively prevent the drilling rod gliding.
In order to achieve the purpose, the utility model provides a rig with function is prevented weighing down by drilling rod, including the rig body, be equipped with two wire rope that are used for pulling the drilling rod when the drilling rod glides between rig slide afterbody and water just.
Further, a steel wire rope length adjusting mechanism is arranged at the tail part of the drill slide way; the steel wire rope length adjusting mechanism comprises a bottom plate arranged on the tail part of the drill slide way, two mounting plates vertically arranged on the bottom plate, a wheel shaft rotatably arranged between the two mounting plates, a rotating wheel fixedly arranged on the wheel shaft and a U-shaped rope clamp for fixing a steel wire rope; the steel wire rope is wound on the rotating wheel, and the end part of the steel wire rope is led out of the rotating wheel and fixed on the water closet; the U-shaped rope clamp penetrates through a through hole in the bottom plate, the end part of the U-shaped rope clamp is in threaded connection with the nut, and the U-shaped rope clamp and the bottom plate clamp the steel wire rope tightly.
Furthermore, the water closet is provided with a connecting lug; the end part of the steel wire rope penetrates through the connecting lug and is fixed through a plurality of steel wire rope clamps.
Further, the mounting plate is a bearing seat; a bearing is arranged on the bearing seat; the wheel shaft is fixed on the inner ring of the bearing.
Further, a handle is arranged outside the wheel shaft.
Compared with the prior art, the utility model discloses following beneficial effect has:
through install two wire rope additional between rig slide afterbody and water just for when constructing the big-angle drilling such as roof drainage water, play one when not having the plan and having a power failure rig pressure release back drilling rod gliding and pull the effect to the drilling rod, thereby avoid the drilling rod gliding to injure pedestrian and break the water just.
