The hanging ring 6 comprises two sub hanging rings 601, and the two sub hanging rings 601 are symmetrically arranged in front and back. With the arrangement, the hoisting ring 6 is divided into two sub hoisting rings 601, and the hoisting rope 602 of the hoisting ring needs to be arranged in the middle of the hoisting ring 501 of the winch 5 during core pulling and reloading, so that a triangular gap is reserved in the middle of the hoisting rope 602, the hoisting rope 501 can pass through the middle of the hoisting ring, and interference with the hoisting rope 602 can be avoided in the winding process.

The rack 1 is further provided with a plurality of support frames, each support frame comprises two support legs 11, the two support legs 11 are symmetrically arranged on the front side and the rear side of the I-shaped steel 2, and the upper ends of the support legs 11 are fixedly connected with the rack 1. So set up for this device can place subaerial steadily, the management of being convenient for.

The lower ends of the first and

second end plates

3, 4 are flush with the lower ends of the support feet 11. The arrangement is such that the first end plate 3 and the second end plate 4 also act as support feet 11 for supporting the device.

An angle steel 9 is arranged between the I-shaped steel 2 and the first end plate 3 and the second end plate 4. So set up, improve the rigidity of being connected between I-steel 2 and first end plate 3 and the second end plate 4, prevent to warp, cause the incident.

The hanging device 8 is a steel wire rope or a chain block. By the arrangement, the steel wire rope or the chain block can provide enough tenacity to hoist the tubular shaft 10, and safety accidents caused by fracture due to insufficient tenacity in the hoisting process are avoided.

The hoist 5 is a 3T hoist. So arranged, it is ensured that the hoist 5 can provide sufficient pulling force to pull the pipe shaft 10.

The lower portion of the first end plate 3 is provided with a guide hole 302 for fitting the pipe shaft 10. With the arrangement, when the core is pulled and the core is returned, the tubular shaft 10 necessarily passes through the guide hole 302 firstly, and the moving position of the tubular shaft 10 is preliminarily determined by utilizing the guiding and positioning function of the guide hole 302, so that the positioning operation is facilitated.

The working principle of the embodiment is as follows:

when the core of the tubular shaft is pulled:

before core pulling, the whole of the device is hoisted by a 25-ton crane through the hoisting ring 601 and moved to align the guide hole 302 with the opening of the tubular shaft 10 of the casing mould. After each tubular shaft 10 is pried by a person by about 50mm and passes through the guide hole 302, the tubular shaft is connected and hoisted tightly with the first monorail travelling crane 7 on the outermost side of the device in parallel by using a steel wire rope, and then a winding rope 501 of the winch 5 firstly bypasses the second guide wheel 401 of the second end plate 4 and is connected with the tail part of the tubular shaft 10. The hoisting machine 5 is started to generate pulling force on the pipe shaft 10, the pipe shaft 10 is slowly pulled out for about 4 meters and then stopped, the second monorail travelling crane 7 is tightly hung with the pipe shaft 10 in parallel connection by using a steel wire rope, the hoisting machine 5 is started again, the pipe shaft 10 is pulled out for about 4 meters, and then the hoisting machine 5 is stopped. According to the method, all the monorail travelling cranes 7 on the windlasses 5 are connected with the pipe shafts 10 in parallel by using steel wire ropes and are hoisted tightly. Finally, the winch 5 is started again to completely draw the pipe shaft 10 out of the casing crystallizer. After the crane moves the device to be placed on the ground, the steel wire rope is loosened to place the tubular shaft 10 on the ground.

When the tubular shaft is installed back:

before the assembly is carried out, the whole of the device is hoisted by a 25-ton crane through the hoisting ring 601 and moved to a position right above the pipe shaft 10 to be carried back, and then the pipe shaft 10 is hoisted by a steel wire rope in parallel connection with all monorail cars 7 of the device and the rear pipe shaft 10 is hoisted to be aligned with the guide hole 302 of the first end plate 3. The winding rope 501 of the winding machine 5 firstly passes around the first guide wheel 301 of the first end plate 3 and is connected with the tail part of the tubular shaft 10. The crane again lifts the apparatus and moves it to the pilot hole 302 aligned with the pipe shaft 10 mouth of the casing mould. And starting the winch 5, wherein the winding rope 501 generates thrust on the pipe shaft 10 to push the pipe shaft 10 to move forwards and is sleeved into the crystallizer of the pipe shaft 10 through the guide hole 302. And (3) loosening the steel wire ropes on the monorail travelling crane 7 one by one to hang the pipe shaft 10 along with the movement of the pipe shaft 10 until all the steel wire ropes are loosened, and finally manually pushing the pipe shaft 10 into a sleeve crystallizer.

Set up two I-steel 2, can operate two hollow shafts 10 simultaneously when realizing loosing core and repacking, improve work efficiency. In the main processes of core pulling and back installation, the winch 5 provides pulling force and pushing force through the rope winding 501, and the efficiency is greatly improved. The pipe shaft 10 is always hung by the hanging device 8 of the device, and the device is also always hung by a crane, so that the pipe shaft 10 and the device cannot fall midway, and safety accidents are avoided.
