Description
Technical field
Architectural engineering construction machines field is the utility model is related to, more specifically, it relates to which a kind of tower crane buffers suspension hook.
Background technology
Crampon, in machinery, handling industry using wide, it is used for tower crane, the suspension hook of currently available technology,
Steel wire is directly connected to base suspension hook, either large or small gap between steel cable and base suspension hook be present, and tower crane is being lifted by crane or unloaded
When, suspension hook load-bearing can undergo mutation, therefore operative employee slowly must lift by crane or put down, but cause unavoidably it is different degrees of rock,
It is also incompatible with today of exquisite efficiency, in the work to move in circles, can make suspension hook be hit load it is larger place production
Raw fatigue damage, reduces its service life.
The Chinese patent that publication No. is the A of CN 103939515 regarding to the issue above discloses one kind and is used for crane hook
On independent hydraulically controlled anti-rotation buffer, including by suspension hook connecting rod, damping sleeve-board, sealing compensation block, guide rail sealing ring,
Spring guide, the interior hydraulic cylinder that flexural spring forms and the outer hydraulic cylinder being made up of piston, foot valve seat, compression spring, accumulator.
By two relatively independent hydraulic cylinder cooperations.Pass through the difference that swings of damping sheet on the up and down motion of piston and connecting rod
Change outer, interior hydraulic cylinder oil pressure, when fluid is absorbed by drag effect caused by flowing valve, slowing down crane arm lifting and suspension hook
Moment dynamic load caused by rotation, so as to play the excessive crane hook of protection stress, extend its working life and increase work
Make the effect of stability.
But above-mentioned technical proposal still suffers from the problem of complicated, installation difficulty, high cost, while construction site is used
Tower crane suspension hook it is relatively large, the buffering effect unobvious when lifting by crane lighter weight building materials.
