Description
Technical field
This utility model relates to tower crane and controls device, and the anti-short circuit of a kind of tower crane limiter controls device.
Background technology
Tower crane, i.e. derrick crane, also known as tower crane, be a kind of crane gear in construction.
The applying working condition of tower crane is relatively severe, tower crane actually used during, when lifting heavy, often there is the situation of overload in tower crane, and this will cause burning of lifting motor, and serious even can make weight from falling from high altitude, jeopardize the life security of surrounding people.Tower crane trolley is during being displaced outwardly simultaneously, the moment of derrick runway girder is constantly increasing, the moment that tower crane is born the most constantly increases, if moment is beyond the maximum moment allowed of tower crane, it is likely to result in the major accident that crane arm fractures or tower crane is tumbled, causes heavy losses to the safety of life and property of the people.Therefore load lifting limiter and limiter of moment are generally individually installed in currently used tower crane, when tower crane hoisting weight or moment have exceeded a certain preset value, load lifting limiter or limiter of moment will export an on-off model and cut off high-speed lifting control loop or trolley outside luffing control loop, now, tower crane will be prohibited high speed lifting heavy or continue outside luffing.
But tower crane actually used in; efficiency of construction and progress is had influence in order to avoid load lifting limiter and limiter of moment action; load lifting limiter and limiter of moment are carried out short circuit by building site electrician the most in violation of rules and regulations; this will cause tower crane to can not get being effectively protected, and tower crane in use exists potential safety hazard.
Utility model content
This utility model is intended to provide a kind of anti-short circuit that tower crane can realize the effectively tower crane limiter of protection to control device.
The anti-short circuit of the tower crane limiter in this programme controls device, including switch board, load lifting limiter and limiter of moment, hoisting circuit and luffing loop it is provided with in switch board, load lifting limiter is connected with the hoisting circuit of switch board, limiter of moment is connected with the luffing loop of switch board, also include intelligent controller, lifting capacity base value module and moment base value module it is provided with in intelligent controller, the input of intelligent controller is provided with the weight sensor that can be used for detecting tower crane hoisting weight and for detecting the displacement transducer of tower crane outside luffing size, the first output interface and the second output interface it is additionally provided with on intelligent controller, first output interface is connected with the input of hoisting circuit, second output interface is connected with the input in luffing loop.
The principle of this programme is: after load lifting limiter and limiter of moment are by short circuit in violation of rules and regulations, when tower crane is operated, weight sensor and displacement transducer detect hoisting weight and the size of the outside luffing of tower crane of tower crane respectively, the signal detected is delivered to intelligent controller by weight sensor and displacement transducer, the signal of weight sensor compares with the lifting capacity base value module in intelligent controller after treatment, and the signal of displacement transducer and weight sensor compares with the moment base value module in intelligent controller after treatment.
When the hoisting weight of tower crane and moment are within normal range, the signal of weight sensor after treatment will be less than setting value with the fiducial value of lifting capacity base value module, the signal of displacement transducer and weight sensor after treatment also will be less than setting value with the fiducial value of moment base value module, now the first output interface and second output interface of intelligent controller will export the switching value of Guan Bi to switch board, now hoisting circuit and the luffing loop of switch board is on-state, and lifting motor and luffing motor in tower crane normally work.
When the hoisting weight of tower crane and/or moment exceed normal range, the signal of weight sensor fiducial value with lifting capacity base value module after treatment will be greater than setting value, the signal of displacement transducer and weight sensor fiducial value with moment base value module after treatment also will be greater than setting value, now the first output interface and/or second output interface of intelligent controller will export the switching value turned off to switch board, now hoisting circuit and/or the luffing loop of switch board is off-state, lifting motor and/or luffing motor in tower crane quit work, now tower crane will be prohibited lifting heavy and/or continue outside luffing.
The effect of this programme is: this programme is by arranging intelligent controller, and be provided for detecting the weight sensor of tower crane hoisting weight and for detecting the displacement transducer of tower crane outside luffing size on intelligent controller, after limiter of moment and weight limitor are shorted, weight sensor and displacement transducer still can detect the duty of tower crane, when weight sensor and/or displacement transducer detect that tower crane is operated in overload condition, output cut-off signals is cut off hoisting circuit and/or luffing loop by intelligent controller, even if so that after limiter of moment and weight limitor are shorted, remain to realize tower crane in the case of hoisting weight and moment overrun, automatically cut off the work of tower crane.Therefore this programme can realize effectively protection all the time to tower crane.
Further, load lifting limiter and limiter of moment all use the mode of aviation plug to be attached with switch board, use the connected mode of aviation plug can be prevented effectively from the short circuit carried out load lifting limiter and limiter of moment in junction.
Further, load lifting limiter and limiter of moment all use the mode of terminal to be attached with switch board, fluid sealant all it is filled with on terminal, people is once had in violation of rules and regulations load lifting limiter and limiter of moment to be carried out short-circuit operation, to be destroyed at fluid sealant on terminal, such that it is able to provide certain information to short-circuit operation in violation of rules and regulations.
Further, it is provided with weight alarm lamp at first output interface of intelligent controller, weight alarm lamp can send light warning when the first output interface is cut-off signals, being provided with displacement alarm lamp at second output interface of intelligent controller, displacement alarm lamp can send light warning when the second output interface is cut-off signals.The light warning signal that displacement alarm lamp and weight alarm lamp send can be used for reminding operator, is apparent from so that the working condition of tower crane is remained to compare by operator.
Further, intelligent controller is additionally provided with the bin that can preserve intelligent controller duty, and memorizer can be used for preserving and record overload, super moment information, it is simple to the tracking in later stage and lookup.
