Abstract
The utility model provides a simple stone removal device for an abrasion drill. The simple stone removal device comprises a cylinder body, the upper portion of the cylinder body is closed, the lower portion of the cylinder body is open, a welded steel pipe is arranged above the cylinder body, the other end of the steel pipe is connected with a flange, and the flange is used for being connected with a drill rod of the abrasion drill; a plurality of holes are formed in the side wall below the cylinder body in the peripheral direction, steel wire ropes extending towards the inner portion of the cylinder body are arranged in the holes in a penetrating mode, the steel wire ropes are fixedly welded to the side wall of the cylinder body at the positions of the holes, and the other ends of the steel wire ropes are crossed mutually. The simple stone removal device for the abrasion drill is simple in structure and convenient to use, can effectively take out boulder stone encountered in the drilling process, enables the abrasion drill to run continuously, does not influence construction progress, and saves construction cost.
Description
Technical field
The utility model belongs to Construction Technology field, specifically a kind of simple and easy stone device that drags for being used in conjunction with abrasion drill.
Background technology
Abrasion drill, because its Clearance requirement is little, mud circulation utilization rate is high and low cost and other advantages, is widely used in bored pile construction.But abrasion drill has been compared a weak point with Churn drill, be exactly in geological condition more complicated, if run into boulder in drilling process, cannot proceed, can only change Churn drill and continue construction, sometimes also need the part backfill of having bored impact holing again.So both affect construction speed, increased again construction cost.
If the boulder at the bottom of hole can be taken out, just can effectively address this problem.
Utility model content
The purpose of this utility model is to provide the simple and easy stone device that drags for for a kind of abrasion drill, can in abrasion drill drilling process, the boulder running into be taken out, and does not affect abrasion drill and works on.
The technical scheme that the utility model provides is: the simple and easy stone device that drags for for a kind of abrasion drill, it is characterized in that: comprise a cylindrical tube, the sealing of cylindrical shell top, lower opening, cylindrical shell top is provided with welded steel pipe, the other end of steel pipe is connected with flange, and this flange is for connecting the drilling rod of abrasion drill; In cylindrical shell lower sidewalls, be along the circumferential direction provided with some perforates, be installed with the wire rope extending to inner barrel in perforate, wire rope is welded and fixed at tapping and cylinder lateral wall, and the other end of wire rope intersects mutually.
As a preferred version of the present utility model, totally 16 of described perforates, do not arrange wire rope in one of them perforate.Wherein, the length of wire rope is less than the internal diameter of cylindrical shell, is greater than the radius of cylindrical shell.
In this programme, the angle of wire rope and cylinder body bottom plane is 10 °, and this structure can effectively prevent that stone from coming off.
The utility model is simple in structure, easy to use, can effectively the boulder running in drilling process be taken out, and makes the abrasion drill can continuous firing, does not affect construction speed, has saved construction cost.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is longitudinal sectional drawing of the present utility model;
Fig. 3 is the layout schematic diagram of bottom wire rope in the utility model.
In figure: 1, flange, 2, steel pipe, 3, cylindrical shell, 4, perforate, 5, wire rope.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and this embodiment is only a better embodiment of the present utility model, and the utility model is not only confined to this.
As shown in Figure 1, the simple and easy stone device that drags for for the abrasion drill that the utility model provides, comprises a cylindrical tube, the sealing of cylindrical shell top, lower opening, cylindrical shell top is provided with welded steel pipe, and the other end of steel pipe is connected with flange, and this flange is for connecting the drilling rod of abrasion drill; In cylindrical shell lower sidewalls, be along the circumferential direction provided with some perforates.
As shown in Figure 2, be installed with the wire rope extending to inner barrel in perforate, wire rope is welded and fixed at tapping and cylinder lateral wall, and the other end of wire rope intersects mutually.Wherein, the angle of wire rope and cylinder body bottom plane is 10 °, and this structure can effectively prevent that stone from coming off.
As shown in Figure 3, totally 16 of the perforates in cylindrical shell lower sidewalls, do not arrange wire rope in one of them perforate.Wherein, the length of wire rope is less than the internal diameter of cylindrical shell, is greater than the radius of cylindrical shell.
During use, this device is connected by the flange on top and the drilling rod of abrasion drill, puts into hole seat.Start rig, in rotary course, can produce downward pressure, the boulder in the seat of hole can with wire rope contact squeeze, because wire rope has certain toughness, boulder can progress in cylindrical shell.Due to wire rope when arranging and cylinder body bottom plane have the angle of 10 °, this angle can guarantee that boulder enters inner barrel rear portion and can come off easily.In addition, one of them perforate of cylindrical shell, for wire rope is set, can guarantee to enter smoothly in cylindrical shell compared with ratchel, also easy to use complete rear smoothly by inner stone taking-up.
If the diameter of abrasion drill drilling rod is 168mm, the external diameter of cylindrical shell can be set to 800mm, cylindrical shell can adopt 10mm steel plate to make, the height of cylindrical shell can be set to 800mm, perforate is 150mm apart from cylinder body bottom plane, and the steel pipe of cylindrical shell top can be set to 170mm, and the external diameter of flange is 250mm, internal diameter is 150mm, and the thickness of flange is 30mm.Preferred Ф 20 wire rope of wire rope, between the preferred 400-405mm of its length.
The utility model is after Reusability, respond well, can salvage the stone of diameter between 200-600mm, can be widely used in abrasion drill construction.
