Abstract

The utility model discloses a novel lifting hook for a crane. The lifting hook is arranged on a crossbeam of the crane and comprises a first force arm, a second force arm, a first bending hook, a second bending hook, a hanging hook and a hanging rod, wherein the first force arm and the second force arm pass through a first pin and are movably connected with the lower end of the crossbeam of the crane; the first force arm is movably connected with the first bending hook through a second pin, and the second force arm is movably connected with the second bending hook through a third pin; the first bending hook and the second bending hook simultaneously pass through a fourth pin, and are movably connected; and the hanging hook is movably connected with the first bending hook through a bolt, and the hanging rod is welded on the second bending hook. When the first bending hook and the second bending hook are open, the hanging rod is exactly positioned below the hanging hook and can be smoothly hooked by the hanging hook; and the hanging hook can be separated from the hanging rod through the rotation in an opposite direction along with the further opening of the first bending hook and the second bending hook. The device can finish the hoisting more easily and safely, is high in speed and efficiency, and does not damage film rolls.

Description

A kind of later-model driving drop hanger

Technical field

The utility model relates to a kind of later-model driving drop hanger.

Background technology

Because the film rolling footpath that institute will lift is big (Ф 45cm at least), and weight is bigger, a general big volume has nearly 3 tons, with common drop hanger very inconvenience, need two people grab two ends that catch on the coil of strip core simultaneously; The film volume of being reeled in the outside has scratch; Can there be certain potential safety hazard if use softer belt to go to hang also in addition, because if need hand be stretched into the equipment rotary area with softer belt operative employee, the diameter that both arms surround is the diameter of not enough steel core also.So find a kind of suitable drop hanger necessary.

The utility model content

The purpose of the utility model is to provide a kind of later-model driving drop hanger, and the utility model can be accomplished lifting more safely, and speed is fast, and efficient is high, and film is rolled up also zero damage.

In order to achieve the above object, the technical scheme of the utility model is:

A kind of later-model driving drop hanger is installed on the driving crossbeam, comprises first arm of force, second arm of force, first hook, second hook, hook and peg; Wherein said first arm of force, second arm of force pass first pin and flexibly connect with driving crossbeam lower end; First arm of force flexibly connects through second pin and first hook, and second arm of force flexibly connects through the 3rd pin and second hook; First hook and second hook pass the 4th pin simultaneously, and make between first hook and second hook and be movably connected; Hook flexibly connects through the bolt and first hook, and peg is welded on second hook.When first hook, when second hook opens, peg just in time is positioned at the below of hook, can let hook tangle smoothly, along with first hook, second hook further open, can let hook break away from peg through opposite spin again.

Described the 4th pin and first pin are all the time on same vertical line.

The beneficial effect of the utility model is: the device of the utility model can be accomplished lifting more safely, and speed is fast, and efficient is high, and film is rolled up also zero damage.

The specific embodiment

Embodiment 1

A kind of later-model driving drop hanger as shown in Figure 1 is installed on the driving crossbeam, comprises first arm of force 1, second arm of force 2, first hook 3, second hook 4, hook 5 and peg 6; Wherein said first arm of force 1, second arm of force 2 pass first pin 7 and flexibly connect with driving crossbeam 8 lower ends; First arm of force 1 flexibly connects through second pin 9 and first hook 3, and second arm of force 2 flexibly connects through the 3rd pin 10 and second hook 4; First hook 3 and second hook 4 pass the 4th pin 11 simultaneously, and make between first hook 3 and second hook 4 and be movably connected; Hook 5 flexibly connects through the bolt and first hook 3, and peg 6 is welded on second hook 4.When first hook 3, when second hook 4 opens up into, peg 6 just in time is positioned at the below of hook 5, can let hook 5 tangle smoothly, along with first hook 3, second hook 4 further open, can let hook 5 break away from peg 6 through opposite spin again.Described the 4th pin 11 and first pin 7 are all the time on same vertical line.

During use, driving being transferred to ground, is fulcrum with the 4th pin 11; Along with driving crossbeam 8 descends; Oppress first arm of force 1 and 2 declines of second arm of force, because lever principle, under first arm of force 1 and 2 effects of second arm of force; First hook 3 that is being movably connected with second pin 9 and the 3rd pin 10, also along with opening to two limits, first hook 3 opens to two limits respectively along the 3rd pin 10 and the 4th pin 11 directions along second pin 9 and the 4th pin 11 directions, second hook 4 second hook 4; Because the 4th pin 11 and first pin 7 on same vertical line, have guaranteed the vertical and symmetrical of hook all the time; First hook 3, second hook 4 are flared to when just in time admitting film rolling steel core diameter, catch on and just in time are positioned at second hook, 4 belows and are fixed on the peg 6 on second hook 4 being connected hook 5 on first hook 3, the film volume top that makes first hook 3, second hook 4 keep these open configurations to move to need to sling; Put down driving crossbeam 8, the position at the 4th pin 11 place is rested on the coil of strip core as fulcrum, continue to make driving crossbeam 8 to descend; After hook 5 and peg 6 were thrown off, the crossbeam 8 of will drive a vehicle raised up, because the fixing of relative position between first hook 3 that has not had hook 5 and peg 6 to catch on to cause and second hook 4; Lifting along with first pin 7; Spurred the lifting of second pin 9 and the 3rd pin 10, and then first hook 3 and second hook 4 are inwardly moved, coil of strip has tightly been embraced; And the steel core lifting of being hung; Pulling force is big more, and it is big more to be converted into the inside cohesive force of hook, does not have and takes off the danger of colluding.After lifting was accomplished, the coil of strip core had rested on the cutting machine, and driving crossbeam 8 at this moment descends; The 4th pin 11 to rest on the coil of strip core is a fulcrum; Oppress first hook 3 and second hook 4 opens, will catch on peg 6, drop hanger is mentioned be removed to the safe place near operator's hook 5; Or put on the ground, once lifting has just been accomplished.The operator just accomplishes lifting more safely like this, and speed is fast, and efficient is high, and film is rolled up also zero damage.
