Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 3, the present invention includes fairlead 8, on fairlead 8 outer surfaces, be evenly equipped withMultiple sleeve pipes 16, the present embodiment has connected four sleeve pipes 16 at the outer surface of fairlead 8, everyOn individual sleeve pipe 16, be equipped with supporting leg 9; These four sleeve pipes 16 are symmetrical arranged between two, Qi ZhongyiOrganize the longitudinal center line of symmetrically arranged two sleeve pipes 16 and other one group symmetrically arranged twoThe line of the longitudinal center line of sleeve pipe 16 is vertical and coplanar, and all with the axle of described fairlead 8To vertical and intersectant centerline. Fairlead 8 is hollow column structure, and this fairlead 8 is divided into a left sideRight two halves, are divided into a left side half fairlead 13 and right half fairlead 15 that are all semicircle shape, and left halfFairlead 13 with on right half fairlead 15, be respectively connected two sleeve pipes; Left half fairlead 13 and the right sideThe end face edge of half fairlead 15 is respectively provided with four contiguous blocks, all has connecting hole on contiguous block7; In the time of boring, left half fairlead 13 and right half fairlead 15 are enclosed within respectively the impact of rigOn device 4, inserted in connecting hole 7 by connecting bolt 14, left half fairlead 13 and the right side are partly ledFixing to cover 15.
As shown in Figure 4, the arbitrary sleeve pipe 16 in four sleeve pipes 16 is away from one end of fairlead 8Be connected with expansion bracket 11 by adpting flange 6; Remaining 16 of three sleeve pipe can by lengthThe adjusting rod 10 of adjusting connects expansion bracket 11.
As shown in Figure 5, in four sleeve pipes 16 any two adjacent sleeve pipes 16 away from fairleadOne end of 8 is connected with expansion bracket 11 by adpting flange 6 respectively; The sleeve pipe that two other is adjacent16 connect expansion bracket 11 by length-adjustable adjusting rod 10.
Adjusting rod 10 comprises multiple nested telescopic joints successively, and expansion bracket 11 is flexible with first jointJoint is connected, between each telescopic joint and between minor details telescopic joint and sleeve pipe 16 respectively by protruding andGroove is fixed; In the time that adjusting rod 10 carries out length adjustment, the projection on a telescopic joint fallsIn the groove on another telescopic joint, the length of these two telescopic joints regulate complete.
Expansion bracket 11 of the present invention is mechanical scissor-like jack, belongs to prior art, comprisesLever and set screw 12, one end of lever is saved telescopic joint with the head of adjusting rod 10 and is connected, anotherOne end is connected to respectively on the hole wall of foundation pit in the time of boring, makes by rotation set screw 12Telescopic lever.
Operation principle of the present invention is:
As shown in Fig. 2 A～Fig. 2 E, foundation pit has five types, 4,8,12,16,20 hole,Bore diameter and spacing and quantity are different, draw to dig cushion cap openings of sizes and differ. Due to variousThe distance of boring type hole centre distance foundation pit wall is more or less the same, by regulating expansion bracket11 adjust length with adjusting rod 10 digs size and different anchor holes position to adapt to Bu Tong drawing of sizePut.
As shown in Figure 1, rig stand 1 is placed on and is drawn that to dig cushion cap top fixing by base 3, boresBar 2 connects impactor 4 and deeply draws and dig 1.5 meters of left and right, cushion cap below, the pre-drilling rod 1 of the portion that addsRice, aims at the boring of anchor hole centre mark for unsettled 2.5 meters, and boring location and perpendicularity are by locator5 ensure. Locator 5 is enclosed within on impactor 4, and gap is very little, and surrounding is by adjusting rod 10Adjust length with expansion bracket 11 and be connected to draw and dig on cushion cap wall, make drilling rod 2 and impactor 4Stablize and do not move. Be specially:
When rig is fixed, when impactor 4 is aimed at anchor hole centre mark, by left half fairlead 13Be enclosed within respectively on the impactor 4 of rig with right half fairlead 15, fixing with connecting bolt 14,And support by each supporting leg 9. Then by adjusting rod 10 by the interior pull-out of sleeve pipe 16, cooperation is revolvedTurn set screw 12 and make expansion bracket 11 flexible, locator 5 is accurately located, execute while boring and ensureThere is not drill bit and swing, realize perforation of boring machine quick, hi-Fix. Pierce set depth fixedBehind position, utilize set screw 12 to regulate expansion bracket 11, make surrounding depart from wall, then unscrew evenConnecting bolt 14, decomposes left and right half fairlead 13,15, and convenient taking-up, needn't dismounting drilling rod2 and impactor 4, increase work efficiency and reduce labor intensity. Then, again by impactor4 aim at anchor hole centre mark to be bored, and by aforesaid operations, locator 5 are accurately bored locationHole.
Can draw to dig under platform in the difference of 1.2m～1.8m and accurately move in order to realize locator 5Moving location, by making the adjusting rod 10 of different size, makes locator 5 meet difference and draws and digSpan demand under platform; By expansion bracket 11 fine adjustments to each anchor hole in same levelPosition, four expansion brackets, 11 tops are pressed on the foundation pit wall of four sides with fixed guide cover 8.
