Summary of the invention
For the deficiencies in the prior art, the utility model provides one just to dismantle stationary crane, flexible and convenient to use, and safety is high, and limitation is little, is also convenient to dismounting when needed and reinstalls to other Work places.The technical solution adopted in the utility model is:
One just dismantles stationary crane, comprises a base, also comprises crane arm, pull bar, Shears, lifting mechanism, luffing mechanism, swing type mechanism, turntable, suspender;
Described base is removably fixed on pedestal;
Described base top is provided with revolving support, and the revolving support that turntable is arranged on base can do 360 ° of gyroscopic movements;
Shears is arranged on turntable, and the top of Shears and one end of pull bar are rotationally connected; Pull bar is provided with stay cord, and is connected with crane arm top by stay cord; The top of crane arm hangs suspender; End and the turntable of crane arm are rotationally connected;
Lifting mechanism, luffing mechanism and swing type mechanism are arranged on turntable; Lifting mechanism connects the suspender on crane arm by lifting rope; Stay cord on luffing mechanism cylinder lever connecting rod is to control the amplitude of crane arm; Swing type mechanism is connected with the revolving support on base.
Further, base is fixed on concrete pedestal by pre-embedded bolt.
Further, described lifting mechanism comprises lifting motor, hoist change speed gear box and hoist brake; Lifting motor and hoist brake are all connected with the change speed gear box that hoists.
Further, described luffing mechanism comprises luffing motor, luffing change speed gear box, luffing drg; Luffing motor is all connected with luffing change speed gear box with luffing drg.
Further, described swing type mechanism comprises turning motor, revolution change-speed box and driving gear; Turning motor connects driving gear by revolution change-speed box; The fluted disc that driving gear supports with base upper rotary is meshed.
The utility model has the advantage of:
1) adopt electronicly to hoist, luffing, revolution, but hoisting crane uses flexibly, limitation is little.
2) flexible, easy to operate, maintenance maintenance convenience is the efficient weight-lifting equipment of harbour, bulk goods such as stockyard lifting sandstone, coal etc.
Accompanying drawing explanation
Fig. 1 is structure of the present utility model composition schematic diagram.
Fig. 2 is the schematic top plan view of turntable of the present utility model.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
The just dismounting stationary crane that the utility model proposes, as depicted in figs. 1 and 2, comprising: weighing arm 1, pull bar 2, Shears 3, lifting mechanism 4, luffing mechanism 5, swing type mechanism 6, turntable 7, base 8, suspender 9;
The bottom of base 8 is fixed on concrete pedestal 10 by pre-embedded bolt.When needing dismounting transfer tasks place, unclamp fixing nut on pre-embedded bolt, base 8 can be separated pedestal 10.
Base 8 top is provided with a revolving support 801, and the revolving support 801 that turntable 7 is arranged on base 8 can do 360 ° of gyroscopic movements; Shears 3 is arranged on turntable 7, and the top of Shears 3 and one end of pull bar 2 are rotationally connected; Pull bar 2 is provided with stay cord, and is connected with crane arm 1 top by stay cord; The top of crane arm 1 hangs suspender 9; End and the turntable 7 of crane arm 1 are rotationally connected; Turntable 7 is installed lifting mechanism 4, luffing mechanism 5 and swing type mechanism 6; Lifting mechanism 4 connects the suspender 9 on crane arm by lifting rope; Stay cord on luffing mechanism 5 cylinder lever connecting rod 2 can control the amplitude of crane arm 1, the far and near different goods of convenient lifting; Swing type mechanism 6 is connected with the revolving support 8 on base 8.
Lifting mechanism 4 is provided with major-minor Liang Tao mechanism, is the propulsion source of lifting cargo.
The concrete structure of lifting mechanism 4, luffing mechanism 5, swing type mechanism 6 as shown in Figure 2.Luffing mechanism 5 can make crane arm 1 do luffing motion flexibly, makes lifting wider.Swing type mechanism 6 can make rotating platform of crane more than 7 do level 360 ° revolution arbitrarily, makes lifting wider.
