Description

Tower machine plays to rise wire rope reeving structure

Technical Field

The utility model belongs to the technical field of tower machine safety, especially, relate to a tower machine plays to rise wire rope threading structure.

Background

The tower crane, namely the tower crane, is also called as the tower crane for short. Is a hoisting device used in building construction. The industrial classification belongs to machinery- > engineering machinery- > hoisting machinery- > construction hoisting machinery- > tower crane. According to the national standard classification, the model standard of the tower crane is QT, wherein Q represents the crane, and T represents the tower. The standard names in China are the same, and certainly, as our country learns the technology of the tower crane manufactured by the technique of the LiBohai sea and the Botan in France, some manufacturers define the model names according to the foreign coding rule. The tower crane can also be divided into a plurality of varieties according to different design forms, such as a self-elevating tower crane, an inner climbing tower crane, a flat-top tower crane, a jib tower crane, a quick-assembly tower crane and the like. The standard for distinguishing is that many tower cranes, i.e. tower cranes for short, mainly comprise a foundation, a tower body, a jacking part, a rotating part, a lifting part, a balance arm, a crane boom, a crane trolley, a tower top part, a driver cab, a luffing part and the like.

In a traditional tower crane, a traditional rope threading mode of a hoisting steel wire rope of a trolley amplitude-variable tower crane is as follows: the hoisting steel wire rope is wound out from the hoisting drum, passes through the trolley pulley 1, the trolley pulley 2, the hook pulley 1 and the hook pulley 3 in sequence after passing through the top fixed pulley and the root fixed pulley of the crane boom, then passes through the trolley pulley 3, passes through the trolley pulley 2, and finally is fixed on the anti-twist device through the trolley pulley 4. Because the trolley pulleys 1 and 2 and the

trolley pulleys

3 and 4 are coaxially and parallelly arranged, and the hook pulleys are on the same plane, the rope threading mode can cause the deflection of the hook due to the fact that the trolley steel wire rope and the hook steel wire rope are not in the same plane, and is not beneficial to actual construction; in addition, the hoisting steel wire ropes are not in the same plane, so the hoisting steel wire ropes can cut the edges of the pulleys after being stressed, and after the edges of the pulleys are cut off after a long time, the steel wire ropes jump out of the pulley grooves and are clamped, so that major safety accidents such as rope breakage are caused.

In summary, there is a need to develop a rope threading structure of a tower crane hoisting steel wire rope with greatly improved safety to overcome the disadvantages in the prior art.
