Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment 1: salvaging the fishing barrel of erratic boulder in well at well in a kind of pebble layer containing erratic boulder, such as Fig. 1, including
It is fixed in one mentioned on drilling machine and mentions drilling rod 1 and a fishing bucket 2, fishing bucket 2 is cylindrical shape, and fishing bucket 2 selects stainless steel to be made, structure
Firm and wear-resisting, fishing bucket 2 is fixedly connected by connection component 3 with drilling rod 1 is mentioned, when encountering the ovum containing erratic boulder in drilling process
When rock layers, operator can propose that drilling rod 1 changes drill bit into fishing bucket 2, then be salvaged by fishing bucket 2 by the erratic boulder in well is salvaged
Come up.
Such as Fig. 1, the one end for fishing out bucket 2 is erratic boulder input end 4, and the diameter of fishing bucket 2 is 500mm, so the fishing bucket 2 can be salvaged
Diameter is less than the erratic boulder of 500mm, and fishing bucket 2 is open end 5 away from one end of erratic boulder input end 4, and open end 5 is equipped with and is matched therewith
Flip lid 7, flip lid 7 is made of circular steel plate, and the diameter for renovating 7 is less than the diameter of fishing bucket 2, and the diameter for renovating 7 is 400mm, is turned over
The side of lid 7 is hinged on the side wall of erratic boulder outlet end, and flip lid 7 is opposite with the hinged place of flip lid 7 and erratic boulder outlet end side wall
Side by hasp 8 be fixedly connected on fishing bucket 2 on, convenient for operator quickly opens flip lid 7, take out fish out bucket 2 in erratic boulder and
Cobble.
Such as Fig. 1, connection component 3 includes that the steel pipe 31 on 7 centers is being renovated in fixed connection, by steel pipe 31 and flip lid 7
Junction be symmetrically welded with a pair of of reinforcing rib 311 along the lateral wall of steel pipe 31, reinforcing rib 311 is made of triangular steel plate, three
Angular structure is stablized, and the stability connected between steel pipe 31 and flip lid 7 can be improved in the setting of reinforcing rib 311.When encountering bulk
When erratic boulder needs to salvage, operator's drill bit is removed on drilling rod 1 from mentioning, and steel pipe 31 is coaxially set in and mentions drilling rod 1 towards fishing bucket 2
One end, then be fixedly connected with steel pipe 31 with drilling rod 1 is mentioned by clamping screw 312, it is mentioned to quickly be fixed on fishing bucket 2
It is simple and quick on drilling rod 1.
Such as Fig. 2, fishes out and be equipped with two layers of fishing net 6 being made of 16 elastic rods 61 along short transverse on the inner wall of bucket 2, often
Layer fishing net 6 is made of eight elastic rods 61, and eight elastic rods 61 are equally spaced along fishing 2 inner peripheral of bucket, is fished out and is offered ten on bucket 2
Six hole 9(Fig. 3), 9 inner wall of hole is equipped with internal screw thread, and one end of elastic rod 61 is connected with connector 10(Fig. 3), connector 10 is equipped with
External screw thread, when needing to install elastic rod 61 or elastic rod 61 being dismantled and replaced, operator can be by elastic rod 61
On connector 10 be threaded on 9 inner wall of hole, so as to quickly by elastic rod 61 be fixedly connected on fishing 2 inner sidewall of bucket
On, elastic rod 61 is installed or removed and replaced convenient for operator.Elastic rod 61 on upper layer and lower layer fishing net 6 is along fishing bucket
2 inner peripheral is in staggered distribution up and down, can increase the fine and closely woven degree of fishing net 6, it is possible to reduce the cobble of small volume is from gap
The possibility fallen, so that improving the salvaging quality of fishing bucket 2.Meanwhile elastic rod 61 is tilted along fishing 2 inner sidewall of bucket in upward
30 degree of settings, eight elastic rods 61 form upward taper fishing net 6 and enter fishing bucket 2 convenient for erratic boulder.
As Fig. 2 is mentioned drilling rod 1 and drive fishing 2 rotary drilling of bucket, while mentioning drilling rod when being salvaged using fishing 2 pairs of erratic boulders of bucket
1 implements to the downward pressure of fishing bucket 2, and the erratic boulder in the pebble layer containing erratic boulder and cobble enter fishing from erratic boulder upstream end at this time
It is after bucket 2 and gradually compacted in fishing bucket 2, so that elastic rod 61 deforms, one layer of antifriction alloy is enclosed on the outer wall of elastic rod 61
Steel layer 11, since the tool of antifriction alloy steel layer 11 has good wearability, it is possible to reduce elastic rod 61 and erratic boulder and cobble are straight
The possibility that abrasion is generated to elastic rod 61 is contacted, so as to extend the service life of elastic rod 61.When fishing bucket 2 is got into centainly
After depth, operator's starting mentions drilling machine and is gradually lifted fishing bucket 2 out of salvaging well by lifting drilling rod 1, fishes out in bucket 2 at this time
Erratic boulder and cobble deform elastic rod 61 oppositely downward, at this time the erratic boulder in two layers of fishing net, 6 pairs of fishing buckets 2
Play the role of dual support with cobble, so as to salvage the erratic boulder fished out in bucket 2 and cobble.
Operating process: when fish out 2 pairs of salvaging wells of bucket in bulk erratic boulder and cobble salvage when, operator starting mentions drilling machine
To fish out bucket 2 by mentioning drilling rod 1 to be drilled down into and rotate salvaging in well, at this time the erratic boulder in the pebble layer containing erratic boulder and
Cobble from erratic boulder upstream end enter fishing bucket 2 after and gradually fishing bucket 2 in it is compacted so that elastic rod 61 deform, when fish out bucket 2 get into one
After depthkeeping degree, operator's starting mentions drilling machine and is gradually lifted fishing bucket 2 out of salvaging well by lifting drilling rod 1, fishes out in bucket 2 at this time
Erratic boulder and cobble deform elastic rod 61 oppositely downward, at this time elastic rod 61 formed fishing net 6 will
Erratic boulder and cobble are supported and fixed in fishing bucket 2.When fish out bucket 2 from salvage mentioned drilling rod 1 in well and put forward after, operator is by steel pipe
31 remove on drilling rod 1 from mentioning, and then open the hasp 8 of flip lid 7 and erratic boulder outlet end side wall and open flip lid 7, will be floated with reinforcing bar
Stone and cobble take out out of fishing bucket 2.
Embodiment 2: the fishing barrel of erratic boulder in well, such as Fig. 4, with reality are salvaged in a kind of pebble layer containing erratic boulder at well
It applies unlike example 1, connection component 3 includes cylindric supporting block 32 and four connecting rods being connected in supporting block 32
321, connecting rod 321 is made of wirerope, and the diameter of wirerope is 50mm, four one end of connecting rod 321 far from supporting block 32
It is fixedly welded on the side wall of erratic boulder input end 4,4 connecting rods 321 are equally spaced along the outer peripheral edge of fishing bucket 2, so that fishing bucket 2 is mentioned
The side wall uniform force that bucket 2 is fished out when drilling machine is mentioned thereby may be ensured that fishing bucket 2 remains balance in salvaging well, each
Connecting rod 321 is welded with a mountain-climbing lock 322 far from the equal bind in one end of fishing bucket 2, offers confession altogether in supporting block 32
Four through-holes 323 of 322 clamping of mountain-climbing lock, when installation, 322 clamping of mountain-climbing lock is locked at 323 hole wall of through-hole by operator
On, so that connecting rod 321 is fixedly connected with supporting block 32, then supporting block 32 is coaxially set in and mentions drilling rod 1 towards fishing bucket 2
One end, then be fixed together the one end opposite with drilling rod 1 is mentioned of supporting block 32 by fixing bolt 324, installation is simple fast
It is prompt.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
