Description
Technical field
The invention belongs to construction engineering technical field, relate to a kind of guide rail mechanism be fixed on building.
Background technology
Tower crane is that a kind of weight-lifting equipment the most frequently used on building ground has another name called " tower crane ", is called for short " standard knot " with a section spreading, is used for hanging the raw MAT'L of the constructions such as working reinforcing bar, wood are stupefied, cement concrete, steel pipe.Tower crane is a kind of requisite equipment on building site.
The function of tower crane tower crane point bears the upper load that jib stay cord and equilibrium arm stay cord transmit, and directly pass to tower body structure by turntable by the structure member formula of revolution pylon, turntable, bearing etc.There is truncated cone pillar from rising tower top, leaning forward or hypsokinesis truncated cone pillar, herringbone posture and diagonal brace posture.Every last time, capstan head machine all needed to establish counterbalanced weight, and its function is supporting counterbalanced weight, in order to the balancing torque that effect aspect required on Construction designing is contrary with hoisting moment direction.Except counterbalanced weight, its afterbody installing lifting mechanism of being also everlasting.Why homostasis is heavy is placed in equilibrium arm tail end together for lifting mechanism, can play the effect of part counterweight first, second increase the distance between rope reel and pinnacle of a pagoda guide wheel, in order to steel rope row around and avoid disorder cable phenomenon occurs.Inversely, and there is certain proportion relation between equilibrium arm length and boom length in the consumption of counterbalanced weight and the length of equilibrium arm.Counterweight is considerable, and light-duty tower machine generally at least wants 3 ~ 4t, and heavy wants nearly 30t.
Tower crane can be divided into portable tower tower crane and fixed type tower crane.Portable tower tower crane can be divided into again rail mounted, rubber-tyred, truck mounted, crawler type four kinds according to the difference of running gear.Rail-mounted tower tower crane tower body is fixed on walking underframe, and can run on ad hoc track, good stability, work efficiency is high, is thus widely used in building installation engineering.Rubber-tyred, truck mounted and crawler-mounted tower tower crane rail-free device, conveniently moving, but can not on-load walking, less stable.
The tower tower crane of fixed type, according to the difference of installation position, is divided into again attachment jack up and inner climbing type two kinds, adheres to and can raise with building from the tower tower crane of liter and raise, be applicable to skyscraper, the horizontal load transmitted by tower crane is only born in building structure, convenient attachment, but it is many to take structural steel; Inner climbing crane tower is at interior of building elevator, stair case, and climb by a set of bracket and elevator system, jacking is more loaded down with trivial details, but it is few to take structural steel, and do not need installing basis, all deadweight and load are born by building.
No matter be movable tower crane or fixed type tower crane, or fixedly realizing load with ground bottom dependence tower crane bears, or be that building completes bearing load, therefore stability all has much room for improvement.Especially movable tower crane, cannot realize on-load walking, greatly constrain the application and development of movable tower crane.
And if can being combined by crossbeam between tower crane and building, make tower crane can obtain the support of building, then certainly will can improve the stability of tower crane work, therefore, how obtaining a structure that crossbeam and building can be made to realize being connected becomes the technical issues that need to address.
