Some flexible support bar back covers are used on the inside of the bottom nozzle of fishing socket, one end of support bar and the barrel of fishing socket, which are fixed, to be connected
Connect, the other end stretches out to the center of fishing socket.
The improvement of technical solutions of the utility model is further used as, the support bar is straight steel wire rope, described to beat
The bottom barrel of dipper is provided with some fixing holes, and fixing hole is distributed in a ring, and punching press is fixed in one end of each steel wire rope
In corresponding fixing hole.
The improvement of technical solutions of the utility model is further used as, each steel wire rope was used along the fishing socket barrel inverse time
Pin direction is obliquely installed.
The improvement of technical solutions of the utility model is further used as, each steel wire rope is respectively positioned on same plane.
The improvement of technical solutions of the utility model is further used as, the fishing socket top is bound using top plate, on top plate
Provided with some pod apertures.
The improvement of technical solutions of the utility model is further used as, the drive rod is fixedly connected on the center of top plate,
Some floors are provided between the surrounding and top plate of drive rod.
The improvement of technical solutions of the utility model is further used as, the attachment structure is to be located at the drive rod top
Screwed flange.
The beneficial effects of the utility model：In use, changing the drill bit for the rig that circles round into fishing socket, drilling rod drives fishing socket
Rotary drilling, when fishing socket rotates, flexible support bar will be tilted to barrel so that central opening increases, and added automobile and returned
Pressure under rotary drill, can allow boulder to creep into fishing socket, and the mud and stake slag in fishing socket are then discharged by pod apertures, and boulder is bored
Enter to drag for after stone cylinder, stop operating, support bar, which resets, reduces center port, carries brill, can pull boulder out.The utility model uses former material
Material is simple, and fishing success ratio is high, effectively improves convolution rig efficiency of construction.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the utility model front view；
Fig. 2 is the utility model top view；
Fig. 3 is profile at A-A in Fig. 1.
Embodiment
Referring to figs. 1 to Fig. 3, that show the concrete structure of the preferred embodiment of the utility model.Below will specifically
The design feature of bright each part of the utility model, and if being described to during direction (upper and lower, left and right, before and after), be with
Structure shown in Fig. 1 is that reference is described, but actual use direction of the present utility model is not limited thereto.
The utility model provides a kind of convolution small boulder fishing device of rig, including cylinder fishing socket 1 and be located at
The drive rod 2 of the top center of fishing socket 1, fishing socket 1 is fabricated to cylindrical steel cylinder, the diameter of steel cylinder from 6mm steel plates
It can be selected according to Pile Diameter, 10~20cm typically smaller than Pile Diameter.The top of fishing socket 1 is bound using top plate 3, top plate
3 are provided with some pod apertures 4, and top plate 3 is preferably steel plate, and pod apertures 4 are used for mud and stake slag is discharged.Drive rod 2 is used and brill
The steel pipe of bar same specification, the top of the drive rod 2 is provided with the attachment structure that can be detachably connected with drilling rod, the attachment structure
To be located at the screwed flange 5 on the drive rod top.The drive rod 2 is fixedly connected on the center of top plate 3, drive rod 2
Some floors 6 are provided between surrounding and top plate 3, floor 6 is made using the steel plate of triangle.
The bottom of the fishing socket 1 is open, and some flexible support bars 7 are used on the inside of the bottom nozzle of the fishing socket 1
Back cover, one end of the support bar 7 is fixedly connected with the barrel of fishing socket 1, and the other end stretches out to the center of fishing socket 1.Wherein,
The support bar 7 is straight φ 30mm steel wire ropes, and the bottom barrel of the fishing socket 1 is provided with some fixing holes, fixed
