Description

Stair tower mast bar disassembling fixture

Technical field

The utility model is related to the mast provision for disengagement of engineering driller stair tower, particularly stair tower.

Background technology

Engineering driller is easy due to simple, light, operation, be widely used in industry and civil buildings, railway, bridge, The engineering exploration in the fields such as water power.And boring tower is rig one of indispensable equipment in work progress, it is mainly used in probing Drilling rod is removed in work progress or the groundworks such as sleeve pipe are put down.The form of boring tower has many kinds：Such as herringbone tower, four pin towers, building Graduation house etc., wherein stair tower is easy to use due to Stability Analysis of Structures, using relatively broad.

As shown in Figure 1 and Figure 2, whole stair type boring tower is by a upper mainmast 4, lower mainmast 5, two upper sub-struts Bar 3, two lower sub-strut bars 2 are constituted, and whole pylon is arranged on by jointed shaft on the underframe of rig 1.

As shown in figure 3, upper mainmast 4 includes setting the first stull 81 between two first side levers 41, two first side levers 41, and Setting adapter sleeve 6 is respectively welded in the bottom of two first side levers 41, and two adapter sleeves 6 are provided with the first connecting hole 71.Such as Fig. 4 institutes Show, lower mainmast 5 includes setting the between a base 52 and two second side levers 51 that are arranged on base 52, two second side levers 51 Two stulls 82, and the top of two second side levers 51 sets the second connecting hole 72 respectively.First connecting hole 71 of upper mainmast 4 is with Second connecting hole 72 of mainmast 5 is connected with.Upper mainmast 4 and the connection of lower mainmast 5 constitute whole stair type boring tower Mainmast.

For the positional precision of first and second connecting hole 71,72 that ensures upper and lower mainmast 4,5, therefore adopt in process Completed with the mode with brill, i.e., as shown in figure 5, the lower mainmast 5 not drilled to be inserted to the adapter sleeve being welded on upper mainmast 4 In 6, then clamped one time processes first and second connecting hole 71,72 on upper and lower mainmast simultaneously.

After processing, due to the requirement such as follow-up japanning, carrying, before storage, upper and lower mainmast 4,5 need to be disassembled and, Due to upper and lower mainmast 4, longer 5 length, heavier-weight and when have the factors such as the corrosion that triggers not in time of dismounting, cause and tear open The difficulty unloaded.In conventional unloading process, operator taps the in the middle of upper and lower mainmast 4,5 using the instrument such as tup First, two stull 81,82, so that the purpose for taking upper and lower mainmast apart is reached, but this dismounting mode not only takes, effort, And very big influence is caused to the quality of product.

Utility model content

Technical problem to be solved in the utility model is torn open in view of the shortcomings of the prior art, providing a kind of stair tower mast bar Frock is unloaded, it can be by way of time saving, laborsaving and do not influence product quality, and reaching makes the purpose of upper and lower mainmast dismounting.

In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of stair tower mast bar disassembling fixture, Including bearing, a gear is arranged on bearing by the first bearing pin；One rack is arranged on inside bearing, and is engaged with gear；One Tommy bar is connected to the outer end of bearing by the first bearing pin, and installs ratchet, the free end of ratchet by the second bearing pin inside tommy bar It is caught in the slot of gear；In the relative angle bar that is respectively arranged below of bearing and rack, dismounting mast, bearing and rack The angle bar of lower section is respectively clamped at two adjacent first and second stulls of upper and lower mainmast junction.

When the utility model is used to dismantle mast, only the angle bar below bearing and rack need to be respectively clamped into upper and lower mainmast At two adjacent first and second stulls of bar junction, tommy bar is pulled repeatedly, so that it may separate upper and lower mainmast, not only save Save the take-down time, alleviated the labor intensity of operator, and ensure that the product quality of mast.

The utility model can be used for the dismounting of all kinds of engineering drilling equipment, particularly engineering driller stair tower mast bar.

Embodiment

As shown in Figure 6, Figure 7, the utility model stair tower mast bar disassembling fixture it is main by bearing 9, rack 10, bearing 11, First bearing pin 12, the second bearing pin 15, gear 13, ratchet 14, tommy bar 16 are constituted.

Gear 13 is arranged on bearing 9 by the first bearing pin 12.Rack 10 is arranged on inside bearing 9, and is nibbled with gear 13 Close.Ratchet 14 is arranged on inside tommy bar 16 by the second bearing pin 15, and the free end of ratchet 14 is caught in the slot of gear 13.Tommy bar 16 are connected with bearing 9 by installing the first bearing pin 12 of gear 13.An angle bar has been respectively arranged below in bearing 9 and rack 10 17。

When dismantling mast, by the angle bar 17 of the utility model bearing 9 and the lower section of rack 10 be respectively clamped into upper and lower mainmast 4, At two adjacent first and second stulls 81,82 of 5 junctions, tommy bar 16 is constantly pulled, tommy bar 16 is from " pulling to " position position one " Put during two ", the rotate counterclockwise of gear 13 can be promoted with pawl 14 simultaneously, so that the end motion to the right of rack 10.Pull Bar reach " behind position two ", by tommy bar 16 from " position two " turn back " position one ", turning back " during position one ", ratchet 14 Automatically lift, gear 13 is not rotated.

Above-mentioned action is repeated, the constantly end motion to the right of rack 10 can be achieved, finally separates upper and lower mainmast Come, reach and do not damage upper and lower mainmast 4,5 and the purpose smoothly dismantled.

It can change conventional by way of mast is dismantled in the violence of the instrument such as tup by using the utility model, not only save Save the take-down time, alleviated the labor intensity of operator, and ensure that the product quality of mast.

The utility model can be used for the dismounting of all kinds of engineering drilling equipment, particularly engineering driller stair tower mast bar.
