Detailed Description

Referring to fig. 7 and 8, the embodiment describes a large-sized cast iron pipe hoisting device, which is used for hoisting large-sized or ultra-large-sized cast iron pipes, wherein the hoisting device is arranged on the left side and the right side of each large-sized or ultra-large-sized cast iron pipe, and is matched with a steel wire rope, a hoisting tool and a crane to perform operation, so that the large-sized cast iron pipes can be conveniently hoisted, and the installation and the disassembly are simple and easy to implement.

Wherein, fig. 1 to fig. 6 exemplarily show the specific structure of a single large-sized cast iron pipe hoisting device, and the structure and the using method thereof are described in detail below with reference to the accompanying drawings.

The whole hoisting device is of a cylindrical structure equivalent to the inner cavity of the cast iron pipe, the direction of inserting the hoisting device into the cast iron pipe is taken as the inner direction, and accordingly the hoisting device is provided with a wedge-shaped gap from the outer end to the inner end, specifically, the inner end of the hoisting device is a cylindrical part 10, the outer end of the hoisting device is an arc part 20, the whole hoisting device is obtained by linear cutting of a steel cylinder with the thickness not less than 2 cm and is assembled, and as shown in the figure, due to the adoption of the processing mode, the arc part 20 is of a section structure with gradually changed size. A rubber ring 11 is fitted and attached to the outer periphery of the cylindrical portion 10, the rubber ring being annular as a whole, and the rubber ring and the cylindrical portion are fastened together with a plurality of screws, that is, the rubber ring is attached to the outer periphery of the cylindrical portion in the form of an attachment. The outer diameter of the rubber ring is equal to the inner diameter of the cast iron pipe and is used for being plugged into the cast iron pipe, the rubber ring is just plugged into the cast iron pipe, preferably, the rubber ring is made of high-carbon rubber, steel cords and the like are implanted or preset in the rubber ring according to needs, and the wear resistance of the rubber ring is improved. The rubber ring 11 has positive protection significance for a coating or a nitriding layer or a cement anticorrosive layer on the inner wall of the cast iron pipe. A rubber pad 21 is fixed on the outer side of the arc part 20, and the rubber pad is also fixed on the outer surface of the arc part through a screw, so that the rubber pad can be conveniently replaced after being worn. That is to say, have the characteristics that change is convenient and fast. In the same way, steel cords and the like can be implanted or preset in the rubber cushion block 21, so that the wear resistance of the rubber ring is improved. Meanwhile, a hoisting hole 22 is formed in the outer side near the arc part 20, the hoisting hole is a through hole, a conformal reinforcing plate 23 is welded and fixed on the inner side of the arc part corresponding to the hoisting hole, and the conformal reinforcing plate is located right below the hoisting point in a hoisting state to play a role in local reinforcement, namely, the hoisting point is reinforced and supported.

Preferably, a criss-cross support 12 is provided inside the cylindrical part 10, and the support 12 is in a criss-cross shape formed in a horizontal and vertical direction inside, thereby improving the torque resistance of the device.

The specific use method is that firstly, the hoisting hole 22 of the hoisting device is fixed by using the steel wire rope 30 and the steel wire rope lock, and preferably two hoisting holes are used for keeping balance. Then, under the auxiliary action of a crane, the inner end, namely the cylindrical part, of the hoisting device is manually plugged into the cast iron pipe 00, the left end and the right end are respectively provided with one, then the crane is started, the hoisting is carried out by depending on the herringbone steel wire rope, in the hoisting process, the hoisting device is plugged into the cast iron pipe, and under the pulling force of the steel wire rope 30, the hoisting device is more tightly plugged, so that the hoisting device is very safe, and the problem of unhooking cannot exist.
