Abstract

The utility model relates to a minitype tower crane which is composed of a bottom seat, a frame, a lifting arm, a balancing arm, a derricking mechanism, an operator cabin, a lifting mechanism, a rotating mechanism, etc; the utility model is characterized in that a flying casing type rotating mechanism for worm gear pairs, which is composed of a worm gear, a worm, a rotating seat, a steel ball, etc., is used to replace the rotating mechanism on the existing tower crane, and the rotating mechanism which is generally used is that a minor planet drives a big gear wheel; in addition, a steel pipe without gaps is added between the frame and the bottom seat and is taken as a main column to make the frame stable; the utility model can use single-phase power source (220 voltages) and motive power supply (380 voltages) and has the advantages of convenient installation, stable running, strong wind force resistance ability and strong twist resistance ability, and the utility model is an ideal lifting mechanism for building lower constructions.

Description

Small-sized tower crane
Small-sized tower crane is a kind of hoist mechanism, lifting material when being specially adapted to build low-rise building.
At present, tower crane mostly is supporting for the building engineering of building more than the six-storey building, and fashion is built in low-rise building does not have suitable lifting device.In addition, existing tower crane generally adopts small planetary gear to drive crane arm, and the rotating mechanism that equilibrium arm and operator's compartment rotate around big gear wheel is therefore anti-twist, wind resistance power is poor, fluctuation of service, and cost is expensive, and can not use mains lighting supply.
The purpose of this utility model be for build low-rise building provide a kind of safe and reliable, operate steadily, anti-twist, wind resistance power is strong, can use mains lighting supply, hoist mechanism that also can the working power power supply.
The utility model is also the same with existing tower crane, by base, framework, equilibrium arm, crane arm, operator's compartment, luffing mechanism, lift system, except these assemblies, the utility model has adopted and has flown the rotating mechanism that shell-type worm gear pair rotating mechanism replaces small planetary gear to rotate around big gear wheel, and this is one of feature of the present utility model.This mechanism is made up of worm gear, worm screw, rotary seat and steel ball, rotary seat is connected with the body of the tower framework, steel ball all is housed on the slideway of slideway between rotary seat and the worm gear and rotary seat side, this mechanism drives (also usable power power supply) with monophase machine, drives equilibrium arm, crane arm and operator's compartment and rotates together.For increasing anti-twist power and wind resistance power, between base and body of the tower framework, make principal post with a solid drawn pipe, they are linked to be an integral body, this is two of a feature of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is a structural representation of the present utility model
Accompanying drawing 2 is the shell-type worm gear pair rotating mechanism scheme drawing that flies of the present utility model.Referring to accompanying drawing, base 1 is cross, form with I-beam section, framework 3 is connected with base 1 usefulness bolt, 2 is ballast tank, connects with connecting pin 5 between every joint framework 3, and a middle solid drawn pipe principal post 4 saves between the framework 3 with every joint and is connected with flange, flange is connected with four jiaos of framework 3 again, makes them in aggregates.Luffing mechanism 10 is contained on the crane arm 11, and luffing mechanism 10 drives actuated small roadster 12 motions, and actuated small roadster 12 drives pulley suspension hook 13, does the luffing motion.They are contained on the track of crane arm 11.Lift system 8 is contained on the equilibrium arm 7, and lift system 8 drives actuated small roadster 12, makes pulley suspension hook 13 up-and-down movements.Fly shell-type worm gear pair rotating mechanism 14 by worm gear 15, worm screw 18 rotary seats 20 and component set-ups such as big steel ball 16, small ball 17, big steel ball 16 diameters can adopt 25.4mm to be contained between worm gear 15 and the rotary seat 20 in the chute, small ball 17, diameter can adopt 18mm to be contained on the slideway of rotary seat 20 sides, with bolt 19 blind holes, guarantees that steel ball rotates in the original place, make worm gear 15 rotations steadily, can not tilt to the left and right, worm screw 18 usefulness monophase machines (or three motors) drive, and drive worm gear 15 rotations.Rotary seat 20 usefulness bolts are connected with the top of framework 3, and support and stable with step 6.Step 6 is fixed on the flange of principal post 4.This flies shell-type worm gear pair rotating mechanism 14 and drives equilibrium arm 7, and crane arm 11 and operator's compartment 9 rotate together.
The utility model is simple in structure, operates steadily, and cost is low, and is easy for installation, and need not lay the foundations, and is to build the necessary elevator machinery of low-rise building.
