The specific embodiment
As shown in Fig. 4-Fig. 5, the utility model rig rig structure comprises that, perpendicular to the mainmast 4 of rig underframe 7 settings with by the left and right sub-strut bar 3 of train wheel bridge 2 diagonal braces on mainmast 4, this sub-strut bar 3 is less than 90 degree with the angle of underframe 7.
This mainmast 4 is designed to stair type, and is divided into mainmast 9 and lower mainmast 11, between upper and lower mainmast 9,11, by duplex box cupling 25, connects.Upper mainmast 9 is welded through stull water pipe by two rock core steel pipes, and the top of upper mainmast 9 is connected with overhead traveling crane 1 by joint cover 8.Overhead traveling crane 1 is equipped with two pulleys, for wire rope provides winding, and play the guiding role for wire rope.Lower mainmast 11 is designed to flame according to rig appearance and size, consider its processing technology, and lower mainmast 11 is designed to group welding piece.This lower mainmast 11 by independently upper and lower form, by junction plate 13, upper and lower of lower mainmast 11 is welded.Meanwhile, in the above and below of junction plate 13, respectively weld two gussets 14, undercarriage position welding transverse tube 18, to strengthen the stability of mainmast 4 upper and lower supports.The otic placode 21Kong center that this lower mainmast 11 inserts underframe 7, and this lower mainmast 11 is near the spacing beam on rig mid frame 20, and utilize pressing plate and hold-down bolt on mid frame 20 to be fixed.
Left and right sub-strut bar 3 is comprised of upper and lower sub-strut bar 10,19 respectively, and upper and lower sub-strut bar 10,19 is with bolts by box cupling 17.The top connection of left and right upper sub-strut bar 10 is firmly connected with the train wheel bridge 2 on upper mainmast 9.Between left and right lower sub-strut bar, utilize U-shaped screw to be connected with middle girder 12, draw hook 16 and a pair of leading block 5 are installed on middle girder 12, this can prevent wire rope play to leading block 5 when erecting tower.The bottom assembling wheels 15 of left and right lower sub-strut bar 19 and the anchor ear 6 being connected with rig underframe 7 when advancing, wheel 15 can be converted to travel condition by rig in conjunction with the draw hook 16 on middle girder 12 after putting tower.
Below perpendicular tower-like condition of the present utility model is specifically described:
Rig, before entering work-yard, need to be arranged work-yard.According to place situation, at rig putting position, complete sleeper.After place to be onstructed arranges, rig is dragged to construction plant, according to position, aperture, is well placed rig.That with instruments such as cushion block, belts, unclamps lower sub-strut bar 19 and underframe 7 is connected anchor ear 6, and rig and underframe 7 levels are put on sleeper.
As shown in Figure 6, vertical rod 22 is inserted to rising of rig mid frame 20 rear sides and pull out in a hole, check whether the pulley rising in bridge 23 of vertical rod 22 upper ends installs firm and flexible rotating.Upper and lower mainmast 9,11 is connected by duplex box cupling 25, and upper mainmast 9 tops are fixing overhead traveling crane 1 by joint cover 8 and bolt.After having been walked around to pulley in bridge 23, two pulleys on overhead traveling crane 1, wire rope is fixed on mainmast 4.During perpendicular tower, a bridge 23 can be lineoutofservice signal pull provides guiding.The mainmast connecting 4 is assigned on the hole bearing pin of rig underframe place otic placode 21 again.Lay down pressing plate and hold-down bolt on mid frame 20, so that perpendicular tower simultaneously.
One end of wire rope is snapped in the card rope hole in hoist drum, start diesel engine, speed change handgrip is adjusted at a slow speed, transfer handgrip is adjusted to elevator position, clutch closes, regulate band-type brake handle, make hoist drum with suitable speed rotation, guarantee that wire rope is wrapped in hoist drum in an orderly manner.Then the wire rope other end has been walked around to the pulley in bridge, two pulleys on overhead traveling crane successively, be pulled to transverse tube 18 places of mainmast 4, with rigging shackle, wire rope has been fixed.
During perpendicular tower, again start hoist, wire rope is wound on reel gradually, mainmast 4 slowly rises under the pulling force of wire rope.Meanwhile, near overhead traveling crane 1, arrange operator to assist certain altitude is lifted in the upper end of mainmast 4, make perpendicular tower more smooth and easy.When mainmast 4 is close to after the spacing beam at mid frame 20 places, with pressing plate and hold-down bolt, be fixed.Two upper sub-strut bars 10 insert respectively sub-strut bar 19 twice, and utilize screw rod fastening by box cupling 17, then manually slowly lift, and are pushed into and cross the position vertical with underframe 7, lean on mainmast 4.Operator, by the transverse tube 18 on mainmast 4, climbs to pylon top, and the train wheel bridge 2 use bolts of upper sub-strut bar 10 and upper mainmast 9 are connected.Finally, according to the situation after boring tower assembling, at underframe both sides welding support bar, and set up a diagonal brace to vertical rod, the stability while being more conducive to guarantee boring tower work.
When probing end-of-job, putting tower, to be converted to rig travel condition step as follows: first dismantle the miscellaneous part except lower sub-strut bar (comprising middle girder part) 19, vertical rod 22 and a bridge 23 in boring tower.Then, lower sub-strut bar 19 is pressed, use belt together with underframe 7 bolts, is raised lower sub-strut bar 19 lower sub-strut bar 19, at underframe, places the suitably cushion block of height for 7 times.Depress down again sub-strut bar 19, take out belt, lower sub-strut bar 19 and the little axle of underframe 7 is tight by anchor ear 6 bolts, both are connected.Can pass through trailer traction draw hook 16, by wheel 15, at ground running, and rig is converted to travel condition.
