Abstract
The utility model relates to a drill bit deepwater fishing device, which is composed of a circular steel cylinder, a steel cable, a draw rod, a flange plate, a reducing, etc. The top and the bottom ends of the circular steel cylinder are provided with flange rings, the draw rod is connected with the reducing via the flange plate, the reducing is connected with the circular steel cylinder as integration, and the periphery of the lower inner wall of the circular steel cylinder is provided with a shackle connected with the steel cable and an L-shaped buckle. When used, the circular steel cylinder can be arranged in a drill hole and can cover the dropped drill bit, the circular steel cylinder can generate radial deformation with a pulling force of the steel cable so as to cover the drill bit, and then the drill bit can be fished out from deep holes with the action of a drill rod. The utility model has the advantages of novel design, simple structure and convenient operation.
Description
The utility model relates to a kind of instrument of salvaging drill bit in deep water.
In large-scale bridge construction, the construction of pier footing generally is to adopt the boring placing, when 100 meters of drilling depths, rock bit that rig the is joined ton that weighs surplus in the of 10, the length of drilling rod is generally about 120 meters, because the hole depth drilling rod is long, moment of torsion is big, and at the bottom of falling the hole, Salvage Dives is generally adopted in the salvaging of drill bit to drill bit very easily twisting off drilling rod below 100 meters, and only 60 meters of the dark limit of diving, because the water operation is subjected to the several factors restriction under the diver, when the geology condition was relatively poor, the diver was dangerous at the hole sole, for drop a salvaging difficult problem in the deep hole more than 100 meters of drill bit, domestic unresolved always.
The novel purpose of this reality provides a kind of drill bit deep water fisher, to solve the salvaging problem of drill bit in the deep hole.Particularly fall salvaging problem in the deep hole more than 100 meters for drill bit.
The technical scheme of the utility model drill bit deep water fisher is: it is made of circular steel cylinder (1), wire rope (2), pull bar (3), flange (4), reducing (5), shackle (6), flange circle (7), L type hook (8), upper and lower end parts at circular steel cylinder (1) is provided with flange circle (7), pull bar (3) is connected with reducing (5) by flange (4), reducing (5) is connected as a single entity with circular steel cylinder (1), be provided with shackle (6) and L type hook (8) around the lower inner wall of circular steel cylinder (1), wire rope (2) is connected with L type hook (8) with shackle (6) respectively.
The utlity model has advantage novel in design, simple in structure, easy to use.In the construction drill operation of pier footing, fall salvaging problem in deep hole more than 100 meters for solving drill bit, a kind of instrument is provided.
Below in conjunction with accompanying drawing the utility model is carried out detailed narration:
Accompanying drawing 1 is the structural representation of this practical drill bit deep water fisher.
Accompanying drawing 2 is that A among Fig. 1---A is to view.
Accompanying drawing 3 is that B among Fig. 1---B is to view.
With reference to the accompanying drawings shown in 1,2,3, the utility model drill bit deep water fisher is made of circular steel cylinder (1), wire rope (2), pull bar (3), flange (4), reducing (5), shackle (6), flange circle (7), L type hook (8), be provided with flange circle (7) in the top and the bottom of circular steel cylinder (1), pull bar (3) is connected with reducing (5) by flange (4), reducing (5) is connected as a single entity with circular steel cylinder (1), be provided with shackle (6) and L type hook (8) around the lower inner wall of circular steel cylinder (1), wire rope (2) is connected with L type hook (8) with shackle (6) respectively.
When the utility model fisher uses, the pull bar (3) of fisher is connected with the drilling rod of drill bit, wire rope (2) is connected with the transition machine, the circular steel cylinder (1) of fisher is put into boring and covered the drill bit that drops, pulling force by wire rope (2) makes circular copper tube produce radial deformation to fasten drill bit, by the effect of drilling rod, just drill bit can be salvaged from deep hole again.
Claims (1)
- Drill bit deep water fisher is made of circular steel cylinder (1), wire rope (2), pull bar (3), flange (4), reducing (5), shackle (6), flange circle (7), L type hook (8), it is characterized in that being provided with flange circle (7) in the upper and lower end parts of circular steel cylinder (1), pull bar (3) is connected with reducing (5) by flange (4), reducing (5) is connected as a single entity with circular steel cylinder (1), be provided with shackle (6) and L type hook (8) around the lower inner wall of circular steel cylinder (1), wire rope (2) is connected with L type hook (8) with shackle (6) respectively.
