Abstract
The utility model discloses a small-sized quick-assembling tower crane. The small-sized quick-assembling tower crane consists of a tower machine body consisting of standard sections, a rotary platform assembly, a balance arm, a hoisting arm assembly and a balancing weight, wherein the tower machine body is formed in the way that two standard sections are butted and then are connected through a high-strength bolt; the rotary platform assembly is fixed on the top of the tower machine body through a high-strength bolt; the balancing arm is connected with the rotary platform assembly through a pin shaft; the hoisting arm assembly is connected with the rotary platform assembly through a pin shaft; the balancing weight is placed on the balancing arm to perform weight balancing. The small-sized quick-assembling tower crane has the characteristics of few and small structure units, simplicity in manufacturing, convenience for mounting, low-cost transportation, high strength and high safety.
Description
Technical field
The utility model belongs to the construction machinery equipment technical field, especially relates to the small-sized fast-assembling type tower crane of a kind of rated load weight 2000kg left and right.
Background technology
At present, Mini-tower hoist one is to adopt common little tonnage tower machine both at home and abroad, during erection cost, transportation is inconvenient, the 2nd, adopt car chassis or chassis special to tow, adopt steel rope system or hydraulic efficiency pressure system to set up, realize voluntarily or from frame, but due to complex operation, maintenance difficult, the effect of out of reach fast-assembling often.Along with the development of modern times liftings, transportation means and universal, lifting and transportation become very convenient, and quick for installation, transition is small-sized fast-assembling type hoisting crane easily, relatively is applicable to user's request.
Summary of the invention
The purpose of this utility model be to improve the deficiency of prior art and provide a kind of structural unit few and little, manufacture simple, easy for installation, transport cheap, intensity good, safe small-sized fast-assembling type tower crane.
The purpose of this utility model is to realize like this, a kind of small-sized fast-assembling type tower crane, the tower body be comprised of standard knot, turntable assembly, equilibrium arm, lift arm assembly and clump weight form, be characterized in being connected and fixed and forming with the high strength spiral shell after the tower body is by two joint standard knot docking, the turntable assembly is fixed on tower body top by high strength bolt, equilibrium arm is connected with bearing pin with the turntable assembly, lift arm assembly is connected with bearing pin with the turntable assembly, places clump weight and carry out counterweight on equilibrium arm.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is to be connected and fixed and to form with the high strength spiral shell after the tower body is docked by two joint standard knots, the turntable assembly is fixed on tower body top by high strength bolt, equilibrium arm is connected with bearing pin with the turntable assembly, lift arm assembly is connected with bearing pin with the turntable assembly, place clump weight and carry out counterweight on equilibrium arm, the utility model project organization unit volume is little, and mutual connection is simple; Structural unit is few, only have 5 structure module unitss, realize function quick for installation, underframe is connected with basis and only adopts 16 holding-down bolts, tower body connects and only adopts respectively 8 high strength spiral shells, crane arm and equilibrium arms to be connected the employing bearing pin with turntable with underframe and turntable, only with 8 tons of wheel cranes, get final product installation in 30 minutes, convenient transportation, the fast-assembling tower machine of a playscript with stage directions utility model only needs the standard high cube container of 40 feet.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Fig. 1 is a kind of structure of the present utility model.
The specific embodiment
Embodiment, a kind of small-sized fast-assembling type tower crane, with reference to Fig. 1, to be connected and fixed and to form with the high strength spiral shell after tower body 2 is docked by two joint standard knots 1, turntable assembly 3 is fixed on tower body 2 tops by high strength bolt, and equilibrium arm 4 is connected with turntable assembly 3 use bearing pins, and lift arm assembly 5 is connected with turntable assembly 3 use bearing pins, place clump weight 6 and carry out counterweight on equilibrium arm 4, this forms a kind of structure of the present utility model.
When the utility model is installed, one joint standard knot 1 is hung onto on underframe and with holding-down bolt and is connected and fixed, be connected and fixed and form tower body 2 with the high strength spiral shell after lifting second section standard knot 1 and the accurate joint 1 of first segment docking, assemble on the ground turntable assembly 3, after docking with tower body 2, lifting turntable assembly 3 is connected and fixed with the high strength spiral shell, 4 bearing pins of lifting equilibrium arm 4 and turntable assembly 3 use are connected, and place a clump weight 6, assemble on the ground lift arm assembly 5, 3 bearing pins of weighing arm assembly 5 and turntable assembly 3 use of slinging connect, and place remaining clump weight 6, wear around hoist rope trial run and run and get final product.
