Abstract

The utility model relates to a multipoint drilling machine having double drive and longitudinally arranged, comprising an upper bottom bracket, a lower bottom bracket, a ram and two groups of actuating devices. Each actuating device comprises a motor, a gear-box drive shaft and a vertical feed speed changing mechanism. A pylon bent is fixed on the upper bottom bracket, and is provided with a rotary plate which is driven by two groups of angular wheel mechanisms and a frame which is operated by a chain-drive mechanism and provided with a plurality of rotary heads. The upper parts of a plurality of drilling rods are respectively connected with the rotary heads, each drilling rod passes through each rotary shaft of the rotary plate respectively, and the lower end of each drilling rod is provided with a drilling head. Each rotary shaft of the rotary plate drives each drilling rod to rotate respectively, and the rotary plates and the drilling rods are all arranged longitudinally.

Description

Two driving longitudinal rows are put the multiple-drilling machine of rotating disk

The utility model relates to a kind of two multiple-drilling machine that longitudinal row is put rotating disk that drives, it belongs to the employed engineering driller of diaphragm wall engineering in the civil construction field, it is applicable to long and narrow place operation, encloses basic reinforcing engineerings such as curtain as diaphragm wall, impervious wall, foundation ditch.

In the prior art, usually use many drilling rods rig of underlying rotating disk, it drives with single shaft, its rotating disk can vertically be arranged, its shortcoming is: single shaft drives the moment of torsion that each drilling rod is obtained and is subjected to very big restriction, so rig can not adapt to the requirement of the construction works under the various MODEL OVER COMPLEX TOPOGRAPHY.In addition, the many drilling rods engineering driller that also has a kind of twin shaft driving of horizontal rotating disk, laterally operation in building construction of continuous concrete wall, promptly on the short side direction of rig underframe, move, so it is bigger that rig itself occupies the place, be not suitable for locating to build diaphragm wall as river dyke or slope of highway etc. at long and narrow sitework.In addition, existing longitudinal row is put the boring tower of many drilling rods engineering driller of rotating disk when holding up and fell, and all adopts the lifting appliance lifting or hangs and unload, and pylon must separate shipments, and under normal conditions, the expense of operation is very expensive like this.

The purpose of this utility model is, a kind of two multiple-drilling machine that longitudinal row is put rotating disk that drives is provided, and it has overcome above-mentioned shortcoming, can be on long and narrow engineering place smooth construction, and the pylon of can holding up voluntarily or fall, and must not lift, hang and unload and separate shipments.

The technical solution of the utility model is: two driving longitudinal rows are put the multiple-drilling machine of rotating disk, comprise underframe and ram, two cover drive unit and power transmission shafts are housed on underframe, and be provided with the bull rotating disk of putting with the longitudinal row of bevel gear mechanism driving, and the swivel head framework of handling with chain-drive mechanism that a plurality of swivel heads are housed, the upper end of described a plurality of drilling rods is connected in the rotating shaft of swivel head, each drilling rod passes each rotating shaft of bull rotating disk respectively, all fixedlys connected with the drill bit that is welded with blade in the lower end of each drilling rod.Described rotating disk and a plurality of swivel head and rotating support a plurality of drilling rods thereon are longitudinal row and put, and promptly along being provided with on the long side direction of described underframe, the pylon of rig then is fixed on the underframe with the pylon seat.

Described a plurality of drilling rod is by two groups of drive units, and the bull rotating disk that promptly comprises motor, gearbox and power transmission shaft and have a bevel gear mechanism drives.

Side at described pylon is provided with hydraulic jack, and an end of this hydraulic jack is hinged on the pylon with hinge, and its other end is bearing in fixed hinge on the bearing of no drive unit one side of underframe.

Advantage of the present utility model is:

(1) because a plurality of drilling rods and drill bit thereof are arranged by vertical on rig, promptly presses the long side direction of rig underframe and arrange, just can on long and narrow engineering place such as river dyke or road slope, build diaphragm wall at an easy rate.

(2) when shifting the rig place, can use holding up and falling of hydraulic jack operation pylon, overcome the tired lock and the expensive lifting cost usefulness of crane loading and unloading on the one hand, avoided on the other hand existing in prior art, in the transportation of rig, highly transfinite.

In conjunction with the accompanying drawings the utility model is elaborated with regard to an embodiment below:

Fig. 1 is a structural representation of the present utility model

Fig. 2 be among Fig. 1 A-A to sectional view

As depicted in figs. 1 and 2, the multiple-drilling machine that two driving longitudinal rows are put rotating disk comprises underframe 1, following underframe 2 and ram 3, they constitute the underframe of hydraulic moving mechanism, on last underframe 1, pylon 4 is housed, it is fixed on the underframe 1 with pylon seat 5, the top of pylon 4 is provided with a plurality of swivel heads 6, in order to drilling rod 7 fixing and its respective number, the middle part of drilling rod 7 is installed in the rotating disk 8 by the geared system of routine, in rotating disk 8, be provided with bevel gear mechanism 9, the two groups of motors 10 that are arranged on the underframe 1 pass through gearbox 11 and power transmission shaft 12, and bevel gear 9 drives rotating disks 8 and also drives each drilling rod 7 rotation.On last underframe 1, also be provided with vertical feed gear 14, it is paid 15 by motor 10 and gearbox 11 and belt pulley and drives, again by being installed in the chain-drive mechanism 18 on pylon 4, day roof beam structure 16 and the swivel head framework 17, a driven rotary framework 17, drilling rod 7 is done the vertical feed campaign with the drill bit 19 that is welded with blade.

When carrying out construction of diaphragm wall, cement paste is entered in hollow drilling rod 7 and the hollow drill bit 19 through sending slurry pipe (not shown) and swivel head 6 by the slush pump (not shown), is sprayed onto in the undisturbed soil 20 by the gunniting hole on the drill bit 19 again; Simultaneously, rig drives drilling rods 7 by above-mentioned drive unit with the bull rotating disk 8 that has bevel gear mechanism 9 and rotates, and each swivel head 6 of maneuvering chain transmission mechanism 18 drives is done feed motion with each drilling rod 7 and drill bit 19, rig need only vertically move the construction that can finish diaphragm wall 21, because the rotating disk 8 of many drilling rods is that longitudinal row is put, promptly the moving direction with rig is identical, and the width of rig is much smaller than its length, therefore, under the situation in long and narrow place, just can successfully construct.

As shown in Figure 1, pylon 4 drives by two groups of hydraulic jacks 22, and an end of this hydraulic jack 22 is hinged on the pylon 4 with hinge 23, and its other end is bearing on the cylinder support 25 of no drive unit one side on the underframe 1 with fixed hinge 24.After predetermined diaphragm wall 21 is finished, with described two groups of hydraulic jacks 22 with pylon 4 to illustrated direction, promptly the reach direction of rig was fallen; When need drilling machine construction, then pylon 4 be holded up with two groups of hydraulic jacks 22.
