Description
Technical field
The utility model relates to a kind of hoisting crane, particularly relates to a kind of double horizontal arm hoisting crane.
Background technology
Along with the development that National Industrial is built, various places start the heavy construction structure occurring the hollow symmetrical such as some large-scale chimney, high-voltage power transmission tower, large cooling columns.These engineering structures often lack the preparation of construction of specialty when constructing, all utilize existing tower machine to carry out operation, in existing tower machine technology, construction for large-scale hollow symmetrical structure has the following disadvantages: the operation while that the feature that generally cannot adapt to symmetrical structure realizing bilateral, operating efficiency is lower; For the engineering structure that upper space is narrow and small, general tower machine cannot realize can only standing on building side from dismounting, and needs of thus having to install larger erecting equipment to meet larger boom length and to play lifting moment; Foundation for tower crane is generally concrete pouring structure, damages and be difficult to realize transition and repeated usage to place.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of double horizontal arm hoisting crane, can bilateral while operation, efficiency is high.
To achieve these goals, the technical solution adopted in the utility model is: a kind of double horizontal arm hoisting crane, comprise tower body, basis, control and monitored control system, lifting mechanism, crane arm, travelling Upon Flexible Adhesion and rotating assembly, be connected with basis bottom tower body, crane arm has two covers, the symmetrical both sides being arranged on tower body, lifting mechanism has two covers, all arrange on the ground, hoist rope is connected with crane arm by the rope sheave beam of crossing on the cardan wheel on basis and tower body top by lifting mechanism, rotating assembly is arranged on tower body and is positioned at below crane arm, crane arm is connected with tower top by flexible draw bar, control and monitored control system are electrically connected with lifting mechanism.
Further, described basis is combined into by some fritters and assembled underframe.
Further, two described cover cargo boom ends are respectively arranged with receives arm train.
Further, two described cover crane arms have the train that independently hoists, luffing train, loading trolley and suspension hook separately.
Further, described tower top bottom is provided with two covers and hoists guiding train, and is furnished with moment and elevating weight detecting device, and top is provided with two covers and receives arm trains.
Further, described control and monitored control system are arranged on the ground.
The beneficial effects of the utility model are: have two covers and independently hoist and changing-breadth system, and by same operating system centralized control, therefore bilateral synchronous, asynchronous operation can be realized flexibly as required, increase work efficiency; Crane arm is arranged symmetrically with and can simultaneously operation, can obtain higher operating efficiency for the engineering construction structure be centrosymmetric; Basis is pin-connected panel, and can recycle and facilitate transition and destroy little to Active workings, and not need pre-cast concrete, it is short that equipment installs the preparatory period; Flexible draw bar, can supporting that crane arm closes up, and be configured with space-saving dolly and platform, can obtain less working space when tearing tower open, improves this tower machine to the comformability of engineering construction structure.
