Description
Technical field
It the utility model is related to a kind of drill bit fishing device, more particularly to a kind of drill bit fishing device with drilling rod.
Background technology
During drilling construction, drill bit often occurs and drops situation, because drill bit used is generally larger in engineering, adds
Upper itself is mostly steel part so that the gross weight of drill bit is very big, and salvaging process also just seems extremely difficult, traditional salvaging side
There is rope sling method in method, rope sling is transferred to the drill bit drilling rod to drop, tense rope sling, slowly lifting, until will fall off drill bit drawing
Go out drilling, but such a method is only applicable to drop the drilling rod situation straight up of drill bit, once the drill bit drilling rod to drop tilts
It is against on hole wall, then rope sling can not entangle drilling rod, so as to the method be used to carry out drill bit salvaging.
The content of the invention
According to above technical problem, the utility model provides a kind of drill bit fishing device with drilling rod, it is characterised in that bag
Drilling rod, steel reinforcement cage, two-way S types hook, steel wire cable are included, cylinder, the reinforcing bar cage top is made using steel bar welding in the steel reinforcement cage
Portion is provided with bar-mat reinforcement, and the bar-mat reinforcement and drilling rod fix welding, and the drilling rod bottom is connected with two-way S types hook, the steel wire
Rope prolongs drilling rod along arriving steel reinforcement cage bottom.
The steel reinforcement cage is highly 0.8m-1.2m, and the steel reinforcement cage diameter is less than drilled pile diameter 10-15cm.
The run of steel exceedes steel reinforcement cage bottom 50cm-80cm.
The steel wire cable is provided with steel reinforcement cage base section and tightens up slip-knot, and what the steel wire cable prolonged, which tighten up slip-knot, prolongs brill
Bar is to steel reinforcement cage bottom with carefully tying up a colligation.
The beneficial effects of the utility model are：Steel reinforcement cage is less than drilled pile diameter 10-15cm for cylinder and diameter, convenient
Sink and larger friction will not occur with drill hole inner wall.The slip-knot of tightening up of steel wire cable prolongs drilling rod to steel reinforcement cage bottom with carefully tying up silk
Colligation, it is relaxed state now to tighten up slip-knot, ensures that steel wire cable tightens up slip-knot to fishing device in sinking watching in drilling
Do not fall off, while after ensureing that fishing device sinks down into drilling rod top position of dropping, boom hoist cable rope, steel wire cable tightens up slip-knot
Easily depart from and collapse with fishing device.Drilling rod bottom is provided with the two-way hook of S types, can be by the drill bit to drop in any position
The quick righting of drilling rod, easily and effectively salvage.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is steel wire cable structural representation.
Such as figure, drilling rod -1, bar-mat reinforcement -2, steel reinforcement cage -3, the two-way hook -4 of S types, steel wire cable -5.
Embodiment
It is shown with reference to the accompanying drawings, the utility model is further described：
Embodiment 1
The utility model provides a kind of drill bit fishing device with drilling rod, including drilling rod 1, reinforcing bar network structure 2, steel reinforcement cage
3rd, the two-way hook 4 of S types, steel wire cable 5, it is cylindric that steel reinforcement cage 3 uses steel bar welding to be made, and is highly 0.8m-1.2m, the steel reinforcement cage
Diameter is less than drilled pile diameter 10-15cm, and the top of steel reinforcement cage 3 is provided with bar-mat reinforcement 2, and bar-mat reinforcement 2 firmly welds with drilling rod 1, bores
The bottom of bar 1 hook 4 two-way with S types is fixedly connected, and the length of drilling rod 1 exceeds the bottom 50cm-80cm of steel reinforcement cage 3, the receipts of steel wire cable 5
Tight slip-knot prolongs drilling rod 1 to steel reinforcement cage bottom with carefully tying up a colligation.
Embodiment 2
When being salvaged, depth where extrapolating the drilling rod to come off according to run of steel first, suitable length is then equipped with
Steel wire cable 5, the fishing device connected is slowly sunk down at the top of the drilling rod to drop, first pull steel wire cable 5 to make salvaging
Device slowly rotates, the drilling rod righting that will fall off using the two-way hook of S types, and the drilling rod for making to drop is in state straight up, this
When should not boom hoist cable rope 5 immediately, first make steel wire cable 5 do it is tight, loosen, tighten, the fine motion of pine, that treats steel wire cable 5 tightens up work
Knot completely falls off and collapsed from fishing device, and the slip-knot of tightening up of steel wire cable 5 fastens drilling rod 1 completely, at this moment can not carry immediately
Rise fishing device, first make steel wire cable do it is tight, loosen, tighten, the fine motion of pine after drill bit after bottom hole thoroughly loosens, then uniformly slowly
Lifting.Occurs the phenomenon for blocking hole wall in lifting process, never strength above carries steel wire cable 5, it should slowly loosen steel back and forth
Wire rope 5, proposed until drill bit outside hole.
Described above is only preferred embodiment of the present utility model, it is noted that for the general of the art
For logical technical staff, on the premise of the utility model principle is not departed from, some improvement can also be made, these, which are improved, also should
It is considered as the scope of protection of the utility model.
