Abstract

The utility model relates to a semi-automatic conversion device for a lifting hook between 1 multiplying power and 2 multiplying power of a movable-arm type tower crane, comprising clamping plates (1), a pulley (2), a shaft (3), a balancing weight (4) and a lifting hook (5), wherein the pulley (2) is assembled between the two clamping plates via the shaft (3); the two clamping plates fix the balancing weight (4) therebetween via a bolt; the balancing weight has no contact with the pulley; and the lifting hook (5) is hung below the pulley (2). The lifting hook is lifted to an arm end while being converted to 2 multiplying power from 1 multiplying power, and then the balancing weight is detached, one end of a rope is fixed on an anti-torsion device at a hoisting arm end, and the lifting hook is converted to a state with the 2 multiplying power. The lifting hook is dropped to the ground while being converted to the 1 multiplying power from the 2 multiplying power, the balancing weight is installed, and the steel wire rope is taken off from the anti-torsion device and fixed on the lifting hook. Manual operation is greatly reduced, and construction efficiency is greatly increased.

Description

Movable arm type tower machine 1,2 multiplying power suspension hook S. A. transfer devices
Technical field
The present invention relates to the adjustment method of movable arm type tower machine 1,2 multiplying power suspension hook multiplying power S. A. transformational structure devices and constructional device.
Background technology
In recent years, the market development of domestic swing arm tower machine was very fast, and each producer has also released the swing arm tower machine of oneself one after another, saw from condition of service, and a lot of producers have adopted 1,2 multiplying power suspension hook design plans, but was artificial conversion multiplying power form.Its 1 multiplying power mode of operation such as Fig. 1, steel rope do not walk around pulley directly and suspension hook fix through wire clips.Its 2 multiplying power mode of operation such as Fig. 2, steel rope walk around pulley and are fixed in the crane arm end.The process that both change each other in 1,2 multiplying powers must be led around steel rope again, and work capacity is big, implements inconvenient.
Summary of the invention
For addressing the above problem, the present invention provides a kind of suspension hook transfer device that can realize the conversion of 1,2 multiplying power S. A.s, the state of equilibrium of suspension hook when regulating 1 and 2 multiplying power switching processs through setting up counterweight block.Keep the suspension hook normal operation, change the fixed form of rope, make to become the enforcement of multiplying power process convenient.
Technical scheme of the present invention is: the suspension hook transfer device comprises clamping plate 1, pulley 2, axle 3, counterweight block 4, suspension hook 5; Pulley 2 is assemblied between the two clamping plates through axle 3; Two clamping plates is fixed on counterweight block 4 between two clamping plate through bolt; Counterweight block does not contact with pulley, and suspension hook 5 hangs under the pulley 2.
When one multiplying power is changed two multiplying powers, suspension hook is raised to the arm end, unloads balance block then, rope one end is fixed on the anti-twisting equipment of crane arm end, suspension hook transfers two multiplying power states to.When two multiplying powers are changed a multiplying power, suspension hook is reduced to ground, balance block is installed, take off steel rope, be fixed on the suspension hook from anti-twisting equipment.
The invention has the advantages that: can significantly reduce manual operation, remove again the complex work of wiring from, construction party can be selected the multiplying power form according to construction requirement in good time, greatly improves operating efficiency, reduces the artificial operational hazards that multiplying power is brought of changing.

The specific embodiment
The suspension hook transfer device comprises clamping plate 1, pulley 2, axle 3, counterweight block 4, suspension hook 5; Pulley 2 is assemblied between the two clamping plates through axle 3; Two clamping plates is fixed on counterweight block 4 between two clamping plate through bolt, and counterweight block does not contact with pulley, and suspension hook 5 hangs under the pulley 2.
Adopt unbalanced structural shape, reach requirement through the balance means.Break original 1 and the form of 2 multiplying power suspension hooks,,, make suspension hook when 1,2 different multiplying through the adjustment counterweight block with a kind of brand-new design idea, the whole center of gravity of suspension hook with hang the thing gravity direction on a perpendicular line, good stability.Through structural innovative design, realized the S. A. conversion of 1,2 multiplying powers easily.1 and 2 multiplying power suspension hooks are realized the S. A. conversion.
Fig. 4 is 1 multiplying power wiring scheme drawing.When changing the work of 2 multiplying powers, the hook balancing pouring weight is unloaded, suspension hook is raised up to crane arm arm point workplatform place; After unclamping screw, arm-tie can rotate around bearing pin, like Fig. 5; Put down the anti-twisting equipment of crane arm end, arm-tie is connected with anti-twisting equipment, split out the bearing pin that is connected of hook and clamping plate with pin.Whole suspension hook multiplying power conversion work is accomplished, and suspension hook is put down getting final product.
When 2 multiplying powers converted 1 multiplying power into, suspension hook was put into ground, loaded onto counterweight block.Other operation is opposite with the time operation of converting 2 multiplying powers to, puts down suspension hook at last and gets final product.
The advantage of this cargo hook gear is: through structural innovative design, reach the auto-conversion function of conversion multiplying power.Save the operating time, solved the problem of new wiring, simple, the easy row of whole multiplying power switching process can improve operating efficiency effectively.
