Description
Technical field:
The utility model relates to a kind of rotary drilling rig drilling rod fall arrest safety apparatus, especially for the fall arrest safety apparatus equipment of rotary drilling rig drilling rod.
Background technology:
At present, rotary drilling rig is novel pile foundation engineering pore-forming equipment in the prior art, in the process of boring the stake hole, because abominable, the factors such as drilling rod is tired, drilling life of drill pipe expires, operate miss of geological conditions, the accident that tends to cause drill rod breaking and fall into a hole takes place, the drilling rod required time of salvaging fracture is long, expense is high, influence the duration process, has been the rotary drilling rig insoluble problem since the midium or long term of constructing.
Summary of the invention:
The purpose of this utility model, provide a kind of rotary drilling rig drilling rod fall arrest safety apparatus, it is to be respectively equipped with square knuckle, wire rope, spade terminal, wire clips in the rotary drilling rig two ends of drill, wire rope connects elevator and drill bit, and when fracture appearred in drilling rod, wire rope pulling was lived the drilling rod of drill bit and part fracture, causality loss is dropped to minimum, time saving and energy saving, expense is low, reaches the purpose of falling behind the protection drill rod breaking.
The utility model rotary drilling rig drilling rod fall arrest safety apparatus takes following technical scheme to realize, it is to be made of spade terminal and square knuckle and wire rope and wire clips, the top of drilling rod is welded with spade terminal, spade terminal connects elevator, the bottom of drilling rod is welded with square knuckle, square knuckle connects drill bit, two ends of drill is respectively equipped with spade terminal and is connected one with square knuckle by wire rope and constitutes the fall arrest safety apparatus, the two ends of wire rope connect respectively junction with spade terminal one end and square knuckle one end be connected and fixed by many wire clips firm, the top of drilling rod connects the driving head, the elevator top connects hoisting rope, the frame of the locomotive mast that is hung, the mast upper end is provided with hoisting rope, and the mast lower end connects hoisting rope, elevator, drive head, the top of drilling rod.During construction, after drilling rod appearance fracture, fall arrest safety apparatus connection elevator, the drilling rod that lifts drill bit and partly rupture lifts out a hole by control hoisting rope and elevator with drill bit and the drilling rod that part ruptures, and causality loss is dropped to minimum.
The effect of the utility model rotary drilling rig drilling rod fall arrest safety apparatus is simple in structure, easy for installation, when fracture appears in drilling rod, wire rope pulling is lived the drilling rod of drill bit and part fracture, causality loss is dropped to minimum, time saving and energy saving, expense is low, is widely used in the rotary drilling rig drilling rod fall arrest safety apparatus equipment in the basic engineering construction of various stakes hole.
