Description
Technical field
The utility model relates to a kind of lifting tower crane based on engineering mechanics.
Background technology
A kind of weight handling equipment that tower crane is the most frequently used on construction site has another name called " tower hoist ", connect long (height) and it be used for hanging, with a section, the starting material that the reinforcing bar of construction, wood are stupefied, concrete, steel pipe etc. are constructed. Tower crane is a kind of essential equipment on building site. The function of tower crane point bears jib stay cord and upper load that balance arm stay cord transmits, and directly passes to tower body structure by turntable by the structure unit formula of revolution pylon, turntable, bearing etc. There is truncated cone pillar from rising tower top, lean forward or hypsokinesis truncated cone pillar, sheerleg formula and diagonal brace posture. Every upper rotary tower machine all needs to establish damper weight, and its function is supporting damper weight, in order to the counter-balance moment that effect aspect required on Construction designing is contrary with hoisting moment direction. Except damper weight, its afterbody installing lifting mechanism of being also everlasting. Why lifting mechanism is placed in balance arm tail end together with damper weight, can play part counterweight effect first, second increases the distance between rope reel and pinnacle of a pagoda guide wheel, in order to wireline row around and avoid disorderly to restrict phenomenon. Inversely, and between balance arm length and lifting beam length, there is certain proportion relation in the consumption of damper weight and the length of balance arm. Counterweight is considerable, and 3��4t generally at least wanted by light-duty tower machine, and heavy wants nearly 30t. Portable tower tower crane can be divided into again rail mounted, tire formula, truck mounted, track type four kinds according to the difference of running gear. The tower tower crane tower body of rail mounted is fixed on walking underframe, can run, good stability on ad hoc track, can walk by band load, and working efficiency height, is thus widely used in construction and installation engineering. The tower tower crane of tire formula, truck mounted and track type without rail set, conveniently moving, but can not the walking of band load, less stable. Fixed tower tower crane, according to the difference of installation position, is divided into again attachment self-rising type and inner climbing type two kinds, adheres to and can raise with buildings and raise from the tower tower crane of liter, it is applicable to Highrise buildings, the horizontal load transmitted by tower crane is only born in building structure, convenient attachment, but it is many to take structure steel;Inner climbing crane tower, at interior of building (elevator raise, staircase), climbs by a set of bracket and lifting system, and jacking is more loaded down with trivial details, but it is few to take structure steel, it is not necessary to installing basis, all deadweight and load are born by buildings.
