Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
The utility model discloses a device for quick aerial tripping in steel structure hoisting, as shown in figure 1, comprises a hoisting ring 1, the hoisting ring 1 is of a U-shaped structure, two ends of the hoisting ring 1 are provided with pin shaft holes 2, pin shafts 3 penetrate through the pin shaft holes 2, one ends of the pin shafts 3 are provided with nuts 4, and the nuts 4 are connected with tripping pull ropes 5; the other end of the pin shaft 3 is provided with a split pin hole 6, a split pin 7 is arranged in the split pin hole 6, and the split pin 7 is connected with an unlocking pull rope 8. The pin shaft 3 is movably matched with the pin shaft hole 2; the inner diameter of the pin shaft hole 2 is 2-3 mm larger than the outer diameter of the pin shaft 3. The cotter pin 7 is movably matched with the cotter pin hole 6; the inner diameter of the split pin hole 6 is 1-2 mm larger than the outer diameter of the pin shaft 3. The length of the cylindrical section of the pin shaft 3 is at least 20mm larger than the edge size of the pin shaft hole 2 on the hanging ring 1.
A tripping method for the above described apparatus of the present invention; as shown in fig. 1, the method is to weld a nut 4 at one end of a pin shaft 3 and tie a tripping pull rope 5 on the nut 4; in addition, an unlocking pull rope 8 is bound on a cotter pin 7 at the other end of the pin shaft 3; when the hoisted component 10 is in place, the sling 9 is loosened downwards, so that the hoisting ring 1 is not stressed; then pulling the unlocking pull rope 8 bound on the cotter 7 to pull the cotter 7 out of the cotter hole 6; and then the tripping pull rope 5 is pulled to pull the pin shaft 3 out of the hanging ring 1, thereby realizing the aim of removing the hoisting shackle from high altitude. The opening angle of the cotter 7 is an obtuse angle; so as to be conveniently pulled out. Therefore, when the cotter 7 is opened, the cotter 7 is only required to be bent to form an obtuse angle, and when the cotter 7 is pulled out from the cotter hole 6 after the bent angle is too large, too much force is exerted to prevent the unlocking cord 8 from being pulled off. When the hoisted component 10 is in place, the distance of the sling is not less than 15CM when the sling is loosened downwards, and the sling is ensured not to be stressed. The unlocking stay 8 and the releasing stay 5 should be long enough to be pulled by a ground operator.
Examples
This example is shown in figure 1. The pin shaft 3 of the shackle is improved on the basis of the traditional hoisting mode, the pin shaft 3 is pulled out by pulling the tripping pull rope 5 on the ground, so that the hoisting ring 1 is separated from the lifting lug 11 on the hoisted component 10, and the aim of hoisting the shackle at high altitude is fulfilled. In the embodiment, the pin shaft 3 made of high-strength round steel with the same strength and the same size replaces the existing stressed rod piece, the cylindrical section of the pin shaft 3 is about 10CM longer than the existing stressed rod piece, and the cotter pin hole 6 is separated from the pin shaft hole 2 by a certain distance so as to be convenient for pulling the cotter pin 7 out of the cotter pin hole 6. And a nut 4 is welded at one end of the pin shaft 3 and used for binding a release pull rope 5. The other end of the pin shaft 3 is drilled with a cotter hole 6 for installing a cotter pin 7. The aperture of the split pin hole 6 is suitable for conveniently installing the split pin 7, and one end of a circular ring of the split pin 7 is bound with an unlocking pull rope 8. After the hoisted component 10 is hoisted, installed and fixed in place, the crane is instructed to loosen the lifting hook 15CM downwards, and after the lifting ring is not stressed, the aerial opening removing operation is carried out.
The apparatus of this example is shown in figure 1. Comprises a lifting ring 1, a pin shaft 3, a tripping pull rope 5, a cotter pin 7 and an unlocking pull rope 8. During specific implementation, the weight of the lifting ring 1 is higher than that of the existing shackle by one grade, the inner wall of a pin shaft hole of the lifting ring 1 is smooth and free of threads, and the material and the size of the pin shaft 3 are the same as those of the original stress rod piece, so that the stability of the shackle and the smooth pulling out of the stress rod piece after the cotter pin is pulled out are guaranteed.
Carrying out high-altitude tripping operation: firstly, pulling an unlocking pull rope 8 on the ground by a person to pull out a cotter pin 7 in a pin shaft 3; secondly, pulling a release pull rope 5 on the ground by personnel to pull the pin shaft 3 out of the pin shaft hole 2 of the hanging ring 1; and thirdly, commanding the crane to lower the lifting appliance to the ground to complete the lifting operation.
The utility model has simple structure and easy manufacture, and solves the problems of severe potential safety hazard caused by tripping of steel structure during high-altitude hoisting and requiring personnel to work high above the ground; the lifting tool is not required to be manually disassembled and broken by people walking up and down and high above the ladder, the using efficiency of the crane is increased, the safety risk of high-altitude operation of the people is reduced, and the material cost and the labor cost for installing the up-down ladder are reduced.
