Fig. 1 is the structure chart boring suspension system according to the umbrella of the embodiment of the present invention.
Label identical in all of the figs indicates similar or corresponding feature or function.
Reference numeral wherein comprises: upper layer disc 2, lower floor's dish 3, winch 4, base 6, steady dish device 7, column 8, movable pulley 9, fixed pulley 10, umbrella brill 11, wire rope 12, steel wire loop 13, horn mouth 14.
Detailed description of the invention
In the following description, for purposes of illustration, in order to provide the complete understanding to one or more embodiment, many details have been set forth.But, clearly, also these embodiments can be realized when there is no these details.In other example, one or more embodiment for convenience of description, known structure and equipment illustrate in block form an.
Below with reference to accompanying drawing, specific embodiments of the invention are described in detail.
Fig. 1 shows the structure of boring suspension system according to the umbrella of the embodiment of the present invention.
As shown in Figure 1, the umbrella shown in the present embodiment bores suspension system, comprises hanging scaffold, umbrella bores 11 and wire rope 12, assembly pulley, winch 4, steel wire loop 13 and base 6.
Wherein, hanging scaffold is dual layer discs, comprises upper layer disc 2 and lower floor's dish 3, is linked together between upper layer disc 2 and lower floor's dish 3 by column 8; In addition, hanging scaffold also can be multilayer disc, convenient construction personnel operation on hanging scaffold, and the number of plies of hanging scaffold is specifically determined according to practice of construction situation; Assembly pulley comprises fixed pulley 10 and movable pulley 9, and movable pulley 9 is positioned at the below of fixed pulley 10, and is linked together by wire rope.
In order to avoid measuring center line, open a through hole at the close position at the center of upper layer disc 2, mounting seat 6 on this through hole, this base 6 suspends fixed pulley 10 in midair by steel wire loop 12.
Lower floor's dish 3 is provided with winch 4, winch 4 will be distal to the distance of base 6 apart from the center of upper layer disc 2 apart from the distance at the center of lower floor's dish 3, winch 4 is linked together by lay winding wire ropes 12 and fixed pulley 10, an enough large through hole (work in place of boring for transferring umbrella is prepared) is opened in the center of lower floor's dish 3, pass through hole for movable pulley 9 and freely activity in through hole, and the movable pulley 9 be positioned at below fixed pulley suspends umbrella brill 11 in midair.
The present invention coordinates the mode of assembly pulley to suspend umbrella brill 11 in midair by winch 4, thus the mode replacing well head to overhang wire rope suspends umbrella brill 11 in midair, because shaft section is large, the mode adopting well head to overhang wire rope is suspended umbrella in midair and is bored 11, it is comparatively far away that it promotes wellbore centre in center to center distance, and umbrella bores 11 easy inclinations even topples over, and adopts winch 4 in the present invention to coordinate the mode of assembly pulley to suspend umbrella brill in midair, because of it, to promote centre distance wellbore centre comparatively near, then umbrella bores 11 and can not tilt and even topple over.
Wherein, in order to increase the stability of hanging scaffold, at the marginal position of upper layer disc 2 and lower floor's dish 3, many covers steady dish device 7 can be installed, be prior art owing to surely coiling device, therefore no longer illustrate in describing the invention.
For the ease of the turnover up and down of well-bucket, 3 collinear positions can be coiled in upper layer disc 2 and lower floor and open at least one horn mouth 14 respectively.
In addition, in a specific embodiment of the present invention, base 6 adopts has some strength and the object that can entangle steel wire loop 13, particularly, adopts i iron as base.
In order to strengthen fixing upper layer disc 2 and lower floor's dish 3, column should adopt the higher material of intensity to make.In a specific embodiment of the present invention, adopt the higher i iron of intensity as column.
In addition, the six arm hydraulic pressure umbrellas of the umbrella drilling in the embodiment of the present invention bore, and winch is slow motion winch.
In order to more detailed description umbrella of the present invention bores suspension system, below will the present invention will be described from working design aspect.
According to the practical experience of constructor, select the slow motion winch of 3 tons, be arranged on hanging scaffold bottom dish apart from wellbore centre 3m position;
Install a long I25a i iron of 2m (object is for geing out of the way measuring center line) apart from upper layer disc center 250mm, i iron installs a Φ 28mm steel wire loop for hanging assembly pulley.
Slow motion winch twines Φ 16mm wire rope and connects suspension assembly pulley, installs U-shaped ring suspension hydraulic umbrella and bore below assembly pulley.Pulley selects lifting capacity to be that 20t remains silent suspension ring type.
The selection of wire rope:
(1) six arm hydraulic pressure umbrellas bore the gross weight coordinating hammer drill is 12.5t;
(2) the minimum breaking force 157KN of 6 × 19-Φ 16-1870 wire rope,
Wire rope total Fracture Force ∑ F is total=157 × 1.24 ÷ 9.8=19.87 tons, then the always disrumpent feelings of 8 wire rope is 158.96 tons, wire rope maximum pendency height 25m, wire rope every hundred meters of weight 0.0944 ton, wire rope weight 0.1888 ton can be ignored, therefore, on this basis, safety factor is 158.96/(12.5+0.1888)=12.53, meet safety code, meet instructions for use.
In addition, depending on country rock situation, when needing eccentric slotting during rock drilling, steel wire loop and I25a i iron according to circumstances need to adjust, and umbrella brill also suitably can depart from certain distance in well to be fixed.
The mode adopting well head to overhang wire rope is transferred umbrella and is bored 11, due to umbrella bore transfer to shaft bottom from well head time, boom hoist cable to wellbore centre distance between 1.4m ~ 1.8m, easy operation, general umbrella bores transfers program and is: transfer umbrella drill change shaft bottom when being about 300mm, stopping is transferred, put base well, by taking hook by force, umbrella brill is pushed in well, transfer umbrella and be drilled into base, connect blast main and water pipe (first wanting little wind only to manage interior dirt) subsequently, connect ball valve, start air motor and make operation of oil pump, supply pressure oil.Handle column oil path valve and rise support arm, stretch out support arm pawl and prop up the borehole wall, overall umbrella loosens hoisting rope a little after boring vertical fixing, and makes it to help umbrella and bores, prevent drilling cramp from toppling over.When column is fixed, necessary vertical bore negative, to avoid hole deviation and to produce card pricker phenomenon.
And adopt umbrella of the present invention to bore suspension system to transfer program that umbrella bores and above-mentioned to transfer the program that umbrella bores identical, when transferring umbrella and boring 11, open winch, coordinate assembly pulley to transfer umbrella by winch 4 and bore 11, when umbrella brill 11 is about 300mm apart from shaft bottoms, stops transferring, put firm banking well, by taking hook by force, umbrella brill is moved to central authorities, and then transfer on umbrella brill 11 to firm banking.
Can be found out by above-mentioned embodiment, umbrella provided by the invention bores suspension system, in the shaft excavation construction of big cross section, can guarantee that the umbrella suspended in midair bores to tilt, ensure construction safety, and, umbrella does not need to contact with hole top signal when boring put-on and delegated, reduces the potential safety hazard of constructor, simultaneously, promote the speed that umbrella bores put-on and delegated, and then accelerating construction progress.
Describe above with reference to accompanying drawing the umbrella proposed according to the present invention in an illustrative manner and bore suspension system.But, it will be appreciated by those skilled in the art that the umbrella proposed for the invention described above bores suspension system, on the basis not departing from content of the present invention, various improvement can also be made to the details that realizes wherein.Therefore, protection scope of the present invention should be determined by the content of appending claims.
