Detailed Description

In order to make the technical means, creation characteristics, achievement purposes and effects of the utility model easy to understand, the following embodiments specifically explain the lifting structure for lifting the roof purline in combination with the attached drawings.

< example >

As shown in fig. 2 to 4, the hoisting structure for hoisting roof purlins is arranged on a hook of a crane in a matching way, and comprises a hook ring 2, a hoisting belt 3 and a traction rope (not shown).

The hoisting belts 3 are n, and n is a natural number more than or equal to 2. Each lifting belt 3 is correspondingly fixed with a purline 4. Two hoisting points are arranged on each purline, and the positions of the two hoisting points correspond to the positions of two end surfaces of the purline respectively 2m towards the center direction. The n hoisting belts are different in length and are arranged in a gradient increasing mode of 2 m. Purlins hung by the hoisting belts with short lengths are arranged above, and purlins hung by the hoisting belts with long lengths are arranged below. In this embodiment, as shown in fig. 2, a hoisting structure for hoisting two purlins simultaneously is illustrated, the purlins 4 include purlins 4a and purlins 4b, the number of hoisting belts 3 is 2, the hoisting belts include hoisting belts 3a with a length of 4m and hoisting belts 3b with a length of 6m, the width of the hoisting belts is not less than 90mm, and the thickness of the hoisting belts is 10 mm. Each hoisting belt is hung on a lifting hook 1 of the crane respectively.

The shackle ring 2 comprises a shackle 21, a shaft member 22 and a locking nut 23. The inner diameter dimension of the upper end portion of the loop is larger than the thickness of the hook, which is generally 20mm, and the inner diameter dimension of the upper end portion of the loop (shown as a in fig. 5) is set to not less than 50mm in this embodiment. The height of the ring buckle (b shown in fig. 5) is set to not less than 120 mm. The loop width of the loop fastener (c shown in fig. 5) is set to be not less than 18 mm. This size setting ensures that the hoist and mount ability of hook ring 2 reaches two purlins of hoist and mount, and when more purlins need hoist and mount, above-mentioned size a, b, c can be according to the corresponding increase of actual conditions. One end of the shaft member 22 is a T-shaped structure, and the other end is provided with a thread. The lower end of the ring buckle 21 is open and is provided with a through hole for the shaft rod to pass through. The upper end of the ring 21 is pressed on the hoisting belt 3, and the lower end of the ring is locked and fixed by the shaft member 22 and the locking nut 23. The end of the shaft member 22 is further provided with a pin hole in which a cotter pin 24 is installed. After the lifting shackle 2 is installed, the lifting strap 3 and the hook 1 are threaded through the lifting shackle 2 as shown in figures 3 and 4. Referring to fig. 6, the installation of the sling of the present embodiment is illustrated, where fig. 6(a) shows the situation where the sling 3a and the sling 3b pass through the hook ring 2 in different directions, and fig. 6(b) and (c) show the situation where the sling 3a and the sling 3b pass through the hook ring 2 in the same direction, and it is preferable to adopt the installation mode where the sling passes through the hook ring 2 in the same direction.

The haulage rope is n, corresponds on every purlin and binds a haulage rope. Preferably, the hauling cable is bound at the middle position of the purlin.

The hoisting structure for hoisting the roof purline has the following working conditions: taking two purlins of hoist and mount as an example, at first bind the hoist and mount point at two corresponding purlin both ends in hoist and mount area, two hoist and mount areas correspond two fixed purlins to bind a haulage rope to every purlin. Then, the middle parts of the two hoisting belts are hung on the lifting hook, then the hoisting rings are installed, after the hoisting rings are installed, the hoisting belts and the lifting hook penetrate through the hoisting hook rings, the hoisting rings are hung on the lifting hook, the hoisting belts are also hung on the lifting hook, a double-safety effect is achieved, and the hoisting belts can be effectively prevented from falling off from the lifting hook. Two purlins can then be lifted at one time. When the lower purline is hoisted to the installation position, the lower purline is fixedly installed, the traction rope on the lower purline is released, and then the upper purline is pulled and fixedly installed. Thus, the hoisting of a plurality of purlines at a time is completed.

The above embodiments are merely preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
