Description
Technical field
The utility model relates to the heavy lifting handling apparatus, the suspension hook that the relates in particular to hoisting apparatus measurement mechanism in drift angle and orientation that dangles.
Background technology
The special equipment that crane transports goods as a kind of lifting has that usable range is wide, operating environment is complicated, use demanding characteristics safely.Crane has polytype and structure, and very most crane all has lifting beam, hoisting mechanism and suspension hook.
Lifting when transporting goods operation, working cycle of crane has Panasonic's suspension hook to hang the lashing tool at suspension hook, mobile suspension hook makes suspension hook overhang appropriate location, goods top, with rigging goods is hung system under suspension hook, lifting hook is so that the suitable tensioning of rigging, mobile suspension hook is adjusted suspension hook and is dangled the drift angle extremely less than permissible value, lifting hook makes goods leave seating surface and observes the goods stressing conditions, the goods stressing conditions meets the demands rear mobile suspension hook to the predetermined placement location of goods, Panasonic's suspension hook makes goods be placed in predetermined placement location, lax rigging is also removed rigging from goods, mobile suspension hook is removed rigging from goods, lifting hook is to suitably highly preparing next working cycle.
In operation process is transported goods in lifting, require goods by the crane vertical lifting, crane does not produce horizontal force action to goods.As far as possible little by the control suspension hook drift angle of dangling, namely on the engineering less than guaranteeing that the job safety permissible value can reach goods by the crane vertical lifting, crane does not produce the requirement of horizontal force action to goods.And lifting hook is when making goods leave seating surface, and the drift angle will produce extra horizontal applied force to goods greater than 0 degree if suspension hook dangles, and the suspension hook larger extra level acting force that goods is produced in drift angle that dangles is also larger.The excessive suspension hook drift angle of dangling will produce excessive horizontal applied force to goods when lifting hook makes goods leave seating surface, cause goods to leave seating surface after amplitude of fluctuation excessive, the safety that jeopardizes goods and operating personnel and crane; As the excessive a kind of extremity in drift angle, during lifting cargo even can cause crane to be tumbled.Moving horizontally in the suspension hook operation process after goods leaves seating surface, because the inertia of goods, also can be so that suspension hook and goods produce swing, out-of-control words, amplitude of fluctuation also can be excessive, affect job safety.These external many cranes lift in the operation process of a goods jointly, require each crane to keep at any time well work compound, need dangle drift angle and to keep at any time the suspension hook drift angle of dangling be 0 of convenient accurately real-time monitored suspension hook.
For the suspension hook drift angle of dangling, its angle myopia is in the suspension hook pivot angle after goods leaves seating surface, and the angle numerical values recited generally obtains by hoisting operation personnel visual inspection or with transit observation, has the large or time taking weakness of error.In operation process is transported goods in lifting, the situation that suspension hook horizontally rotates around wire rope rope center line does not in most cases occur, and this moment is by selecting suitable benchmark can use the suspension hook drift angle of dangling to represent that goods departs from the size and Orientation of vertical lifting center line; Because the impact of various factors, situation about horizontally rotating around wire rope rope center line can occur in suspension hook under a few cases, still can use this moment the dangle size of drift angle of suspension hook to represent that goods departs from the size of vertical lifting center line, it is inconsistent that the direction of drift angle and goods depart from the direction of vertical lifting center line but suspension hook dangles, and need to revise just and can obtain the direction that goods departs from the vertical lifting center line.
In order to overcome the suspension hook weakness that measurement of angle exists of dangling, application number is 200910102367.3 utility model patent disclosed " being used for measuring dynamic measurement device and the method for perpendicularity deviation of hoist lifting hook ", employing is installed on the horizontal survey sensor of suspension hook wire rope rope center line Normal plane, measure the angle that the lift hook steel wire rope departs from surface level, calculate the angle value of the perpendicularity deviation of suspension hook by the triangle relation on the geometry; The method can not determine that the true bearing of drift angle with respect to crane of dangling of rear measurement occurs to horizontally rotate around wire rope rope center line suspension hook.Application number is 200910226102.4 utility model patent disclosed " hanging hook attitude detection device and crane ", adopt angel measuring instrument and processor to obtain in real time the angle between the corresponding coordinate axis in the second relevant coordinate system coordinate axis of suspension hook and the first coordinate system, it is just as the discussion on the easily understood method, there is no essence technology contents or principle and break through, can not determine that the true bearing of drift angle with respect to crane of dangling of rear measurement occurs to horizontally rotate around wire rope rope center line suspension hook simultaneously.Application number is that 201110124401.2 utility model patent disclosed " hoist lifting hook drift angle laser display with monitor arrange " adopts the laser instrument that keeps vertical and with the laser instrument of suspension hook deflection, relatively range of exposures is processed and is obtained the suspension hook drift angle, can not determine that equally the true bearing of drift angle with respect to crane of dangling of rear measurement occurs to horizontally rotate around wire rope rope center line suspension hook." wireless tilt angle sensor of large-scale pipelaying barge suspension hook swing detection integrated with test " that " sensing technology journal " the 12nd periodical in 2007 is stepped on, employing is installed on the obliquity sensor chip of suspension hook and collects the suspension hook inclination data, obtain the suspension hook pendulum angle after being wirelessly transmitted to Computer Processing, can not determine that equally the true bearing of drift angle with respect to crane of dangling of rear measurement occurs to horizontally rotate around wire rope rope center line suspension hook.
Real-time definite suspension hook generation does not horizontally rotate detecting instrument and the method for drift angle with respect to the true bearing of crane of dangling of rear measurement when at present also have in real time to measure suspension hook and dangle the drift angle around wire rope rope center line.
