Description
Technical field
The present invention relates to a kind of clamp structure of square objects, be specifically related to a kind of clamping hanger of the adjustable width for square tubular articles lifting, by rotating shaft being arranged in different adjusting mounting holes for clamping the square tubular articles of lifting different in width.
Background technology
the prefabricated idiosome of square pipe that intensity is lower, is sending into Huo Hongshao stokehold, steam-curing chamber, often with cloth suspender belt lifting transport.For the larger factory of production quantity, the each tying up band of workman, the labour intensity that unloads suspender belt are larger, waste time and energy, and when finished product handling, be also like this.For the tubular articles of larger in batches different size, although needn't too much consider the width of tubular articles while using cloth suspender belt, there is some superiority, efficiency is still lower.For the more coarse square tube in surface, the cloth suspender belt life-span is limited, consumes large in the time of square tube batch hoisting transportation.And use steel rope, owing to being line contact, easily destroy square tube outside face, even structure.
Summary of the invention
The object of the present invention is to provide a kind of clamping hanger of the adjustable width for square tubular articles lifting, this suspender is applicable to several specification tubular articles of known width, clamp strong and unlikely destruction body surface, lifting efficiency is higher, makes simple.
The present invention is achieved like this, a kind of clamping hanger of the adjustable width for square tubular articles lifting, it comprises: suspension hook assembly, cross-arm, steel rope and suspension ring, described suspension hook assembly comprises that connection rotating shaft, the connecting arm installation between L shaped clamping limb, connecting arm, assembly pulley, pulley and connecting arm regulates rotating shaft, adjustment hole, triangle reinforced rib are installed, and described suspension ring comprise suspension ring body and nut; It is characterized in that: suspension hook assembly is connected with suspension ring by steel rope, suspension ring are connected with cross-arm; Described L shaped clamping limb is connected with connecting arm, on connecting arm, be provided with installation adjustment hole, in the middle of two connecting arms, by adjustment hole is installed, connecting arm installation adjusting rotating shaft is set, connecting arm is connected assembly pulley by pulley with the connection rotating shaft between connecting arm, and described L shaped clamping limb and arm portions are divided and be provided with triangle reinforced rib.
Further, described L shaped clamping limb inside face is plane, and it is the reinforced rib of semicircle that there is cross section in outside, and L shaped root transition angular radius is less than R2.
Further, between described clamping limb and connecting arm, become 120 degree.
Further, described clamping limb and connecting arm weld have two triangle reinforced ribs.
Further, described adjusting mounting hole, quantity can arrange flexibly according to product specification.
Further, described each connecting arm upper end is each connects one group of pulley, totally 2 groups, between pulley and connecting arm, is connected by adapter shaft.
Further, described cross-arm is made of channel-section steel, and there are totally 3 of fixed orifices in the middle of cross-arm and two ends.
Further, described suspension ring and cross-arm are clamped and connected locking with three nuts to top respectively.
Further, appeal suspender forms suspension hook assembly, is connected by assembly pulley by steel rope with cross-arm suspension hook.
When use, fall suspender, separately relative L shaped clamping limb in suspension hook assembly, the bottom that makes bottom crotch catch on square pipe, rises travelling crane hook hoisting hanger, drives connecting arm by assembly pulley, the lifting of clamping limb clamping idiosome.
suspension hook assembly has a pair of assembly pulley, and assembly pulley is strained with steel rope, and clamping limb and idiosome contact by side, laminating clamping, clamping is strong, and clamping limb crotch upper surface also for face contacts, has avoided make body surface and structure thereof that intensity lower to be damaged when lifting transport with idiosome bottom surface; Make the suspender of said structure become suspension hook assembly, use a pair of above-mentioned assembly, be arranged on cross-arm, the travelling crane hook suspension ring on cross-arm of slinging, the steady square tubular articles of hoisting transportation.
On connecting arm, have adjusting mounting hole, known square tube specification, in the time that specification is different, by regulating installation rotating shaft to be arranged on corresponding adjusting on mounting hole, ensures that laminating clamps.
Whole suspender strengthens after structure, also can be for the lifting transport of the square objects of other types.
The present invention have advantages of make simple, lifting width adjusting convenience, flexible operation, conveniently moving, time saving and energy saving, to lift by crane efficiency higher.
