Description

Slurry concrete wall groover

The utility model relates to a kind of basic engineering construction machinery, particularly a kind of diaphragm wall groover.

In some basic engineering constructions, need carry out the diaphragm wall fluting.At present common fluting machinery can be divided into three kinds of bucket formula, impact type and swingings by its fluting mechanism.Bucket formula groover is housed in the native slag that cuts in the bucket body with its bucket tooth cutting soil body, transports ground in groove, opening bucket and pouring out native slag, returns the shoveling position then, so repeats work.The soil pressure of cutting this groover depends on that bucket is heavy, and power consumption is big, meets hard ground and wants the preboring guide hole.In order to guarantee the direction of slotting, on the bucket guide plate will be installed, and the width of groove can not be regulated by the decision of the width of bucket, promptly bucket can only be left a kind of underground continuous wall groove of width.The impact type groover is the broken foundation soil of drill bit impact that utilizes different shape, by mud circulation native slag is carried outside outside the groove.The shortcoming of this mode is that fluting speed is slow, because fluting speed depends on frequency of impact and drill bit deadweight, and the power of rig is certain, and frequency of impact and drill bit are conducted oneself with dignity, and the two all has a limit.And the impact shock of drill bit and noise all have certain influence to environment and near building.The swinging groover is to drive bull by submersible motor to bore, the rotary drilling fluting, and native slag is with the circulating mud drain tank.Its shortcoming is that rig is in the groove that is full of water and mud, and motor is fragile to be burnt, and drill bit rig one is insensitive to the variation of ground earthy condition, easily causes mechanical failure, and the bad adjusting of groove width changes groove width and just must change one group of drill bit.In a word, the existing diaphragm wall mechanical bad adaptability of slotting, fluting efficient is low, cost and equipment configuration expense height.

The purpose of this utility model is, improves at the deficiencies in the prior art part, will cut with creeping into to combine, and provides a kind of efficient of slotting high diaphragm wall groover.The further purpose of the utility model is to provide a kind of groove width adjustable diaphragm wall groover.

Composition of the present utility model comprises main frame, frame, guide rail, host output shaft, water tap, drilling rod, the location drill bit, main frame can slide on frame by guide rail, host output shaft is connected with drilling rod, it is characterized in that: (1), drilling rod is connected a horizontal transfer head with the location between the drill bit, transfer head output shaft upper end is connected with drilling rod, the lower end is connected with the location drill bit, cutting cutter shaft and transmission mechanism thereof---the driving wheel of a pair of horizontal direction parallel is housed on the transfer head, driven pulley, follower shaft, drive, spiral distribution bite on the cutting cutter shaft, (2), be with outer drilling rod on the drilling rod, its upper end is connected with host housing, and the lower end is connected with transfer head shell.

The further feature of the utility model is, have by the arc-shaped guide rail groove on crossbeam, track base, the track base, bite wheelbase that positioning bolt is formed from adjusting device, crossbeam is fixed on transfer head top, track base is vertically fixed on the crossbeam two ends, and the arc-shaped guide rail groove on the track base is passed at the two ends of two cutting cutter shafts.

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.

Fig. 1 is the utility model general structure schematic diagram.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the inner vertical view of the utility model transfer head.

Fig. 4 is Figure 1A-A schematic diagram.

As depicted in figs. 1 and 2, the utility model is made up of main frame 17, frame 16, guide rail 15, host output shaft 1, water tap 2, outer drilling rod 14, drilling rod 13, transfer head 4, pair of parallel

cutting cutter shaft

6,7, location drill bit 9.Host output shaft 1 is connected with drilling rod 13, and main frame 17 can slide on frame 16 by guide rail 15, thus the verticality of the underground continuous wall groove that assurance is left.Horizontal transfer head 4 is between drilling rod 13 and location drill bit 9, and transfer head power shaft 12 upper ends are connected with drilling rod 13, and the lower end is connected with location drill bit 9, and the location drill bit has the guide effect of creeping into, and also the foundation soil of transfer subfacies can be removed.The

cutting cutter shaft

6,7 of a pair of horizontal direction parallel passes transfer head 4 and is installed on the transfer head, spiral distribution bite 10 on the axle sleeve 8 of

cutting cutter shaft

6,7, outer drilling rod 14 upper ends are connected with the shell of main frame 17, the lower end is connected with the shell of transfer head 4, when drilling rod 13 rotates, outer drilling rod 14 can the balance drilling rod torque, thereby guarantee that distortion can not appear in the underground continuous wall groove of leaving.

As shown in Figure 3, the bite shaft transmission comprises driving wheel 18, driven

pulley

19,25, follower shaft 20,

drive

22,23,21,24, driving wheel 18 is a conical gear, be contained on the transfer head power shaft 12, driven

pulley

19,25 is two conical gears, be contained on the follower shaft 20, driving wheel is meshed with driven pulley, driving wheel 18 drives driven

pulley

19,25, driven pulley drives two cylinder travelling gears 22 on the

follower shaft

20,23, these two cylinder travelling gears drive respectively and are contained in cutting cutter shaft 6, cylinder travelling gear 21 on 7,23, two cutter shafts are rotated in opposite directions, the bite 10 that is contained on the cutting cutter shaft axle sleeve 8 just cuts soil layer in opposite directions on same plane, leaves underground continuous wall groove.Because two cutting cutter shafts rotate in opposite directions, thereby make the location drill bit when creeping into, not produce lateral force, can not depart from drilling direction.

As Fig. 1, Fig. 2 and shown in Figure 4, two bite wheelbases are made up of the arc-shaped guide rail groove 26 on crossbeam 3, track base 5, the track base, positioning bolt 27 from adjusting device, crossbeam 3 is fixed on transfer head 4 tops, track base 5 is vertically fixed on crossbeam 3 two ends, the arc-shaped guide rail groove 26 on the track base 5 is passed at the two ends of two

cutting cutter shafts

6,7, change two positions of

cutter shaft

6,7 in arc-shaped guide rail groove 26 symmetrically, and with bolt 27 location, promptly reach the purpose of regulating two cutter shaft distances, thereby can leave the underground continuous wall groove of different in width.

The native slag that the utility model fluting is produced is discharged ground by mud circulation, in order to discharge native slag better, further feature as shown in Figure 1, on crossbeam 3, leave one group of water spout 11 that connects water tap 2, water under high pressure is sprayed on the broken native slag of bite milling through nozzle 11 by water tap 2, make it sliming, discharge ground by the main frame water tap again.

The utility model does not in use have impact shock and noise, need not be equipped with other parts and equipment, can directly leave high-precision square underground continuous wall groove, the work efficiency height, and cost is low.
