Description
Technical field
This utility model relates to derrick crane technical field, is specifically related to a kind of tower crane Hoisting Security prior-warning device.
Background technology
In the work progress of building trade, derrick crane (hereinafter referred to as tower crane) belongs to conventional equipment, is used for hanging
The raw material of the constructions such as working reinforcing bar, wood stupefied, concrete, steel pipe.
Tower crane includes pedestal, is fixed on the tower crane frame on pedestal, is placed in the operating room in the middle part of tower crane frame, is placed in
The crane arm at tower crane frame top, the equipment being placed on crane arm and actuating device, this equipment includes volume
Cylinder, steel wire rope, assembly pulley and suspension hook, when actuator drives spool turns, by steel wire rope, assembly pulley
Become the linear motion vertically of suspension hook.At present, in the course of the work, suspension hook is directly to fill with material
Putting, subject the material powerful pulling force to suspension hook, if material is overweight, crane arm can be made unbalance, tower crane inclines
Tiltedly or collapse, the material of suspension falls down, and accident occurs building site complex environment is as easy as rolling off a log, causes personnel to hinder
Die.
Summary of the invention
The purpose of this utility model is to provide a kind of tower crane Hoisting Security prior-warning device, when the weight of suspension material
During the maximum weight exceeded beyond suspension hook and crane arm, this device can avoid tower crane to topple over and cause safety
The generation of accident.
For achieving the above object, a kind of tower crane Hoisting Security prior-warning device, pass including sleeve, embedded post, pressure
Sensor, central processing unit and the alarm device being connected with central processing unit；
Described sleeve is the hollow housing of one end open, and the upper end of described embedded post is provided with protruding and solid by projection
It is scheduled in sleeve；Described sleeve is provided with the opening I for being fixed on tower crane steel wire rope away from one end of its opening；
Described embedded post is provided with the opening II for being fixed in lift hook steel cord away from one end of sleeve；
Described pressure transducer is fixed on the opening part in sleeve, and described projection is placed on pressure transducer；Institute
State central processing unit and alarm device be arranged in tower crane operation room, described pressure transducer and central processing unit without
Line connects；When suspension hook moves down compressive pressure sensor along sleeve and exceedes preset security force value, pass through
Central processing unit triggers described alarm device and reports to the police.
Further, the lower end of described sleeve is fixed with the baffle plate for preventing embedded post from coming off.
Preferably, described alarm device is audible alarm and/or light warning.
Preferably, the one during described central processing unit is single-chip microcomputer, dsp processor, MCU processor.
Compared with prior art, this utility model is provided with pressure transducer, in sleeve in tower crane operation room
The central processing unit arranged and the alarm device being connected with central processing unit.When user is using this prior-warning device
Time, suspension hook is applied pressure by promoting embedded post after the action of gravity of suspension material to pressure transducer.Work as pressure
When the force value that force transducer detects is more than preset security force value, i.e. the weight of suspension material is beyond suspension hook
During the maximum weight exceeded with crane arm, central processing unit then can start alarm device and report to the police, thus points out use
Person's suspension material is overweight, and then avoids tower crane the generation of security incident such as to topple over.This utility model simple in construction,
It is easily achieved, is suitable to promote the use of in construction industry.
