[0022] The structure and working process of the utility model will be further described below with reference to the drawings.

[0023] A coke pot lifting device includes a lifting body, the lifting body is arranged above the coke pot, and a lifting wire rope limiting structure is arranged at the position corresponding to the lifting lug of the coke pot, and the wire rope maintains a vertical direction with the lifting lug through this limiting structure.

[0024] Specific embodiments are as Figure 1 、 Figure 2 shown,

[0025] A coke pot lifting device includes a lifting body 1, the lifting body 1 is arranged above the coke pot, the lifting body is a rectangular structural body, and the four corners of the rectangle are correspondingly arranged above the lifting lugs of the coke pot, and limiting structures are arranged at the four corners; a reinforcing rib is arranged in the middle part of the rectangular body.

[0026] Embodiment 1,

[0027] The rectangular lifting body includes two cross beams 2, three longitudinal beams are arranged between the two cross beams, diagonal braces 3 are arranged between adjacent two longitudinal beams, the two outer longitudinal beams are located inside the ends of the two cross beams, arc plates 4 are arranged at the ends of the two cross beams, and during lifting, the wire rope is limited inside the arc plate 4.

[0028] The outer side of the arc-shaped plate 4 is located at a position perpendicular above the lifting lug.

[0029] Embodiment 2,

[0030] The main structure of the rectangular lifting body in this embodiment is the same as that in Embodiment 1. The difference is that a card slot is arranged on the outer side of the arc-shaped plate to limit the steel wire rope.

[0031] Embodiment 3,

[0032] The main structure of the rectangular lifting body in this embodiment is the same as that in Embodiment 1. The difference is that flexible materials are arranged at the positions where the two cross beams are located at the edge of the coke pot to separate the contact between the cross beams and the coke pot.

[0033] The flexible material is a rubber band wrapped around the edge of the coke pot or a rubber band wrapped around the cross beam.

[0034] In the above embodiments, the cross beams and longitudinal beams are both made of 150*150 H-shaped steel, and the diagonal braces are made of 14# channel steel.

[0035] In the above embodiments, the specific manufacturing method of the device is as follows:

[0036] Select 150*150 H-shaped steel as the cross beams and longitudinal beams, and weld them with 14# channel steel diagonal braces to form a steel frame. Arc-shaped plates are vertically welded at the four corners of the steel frame.

[0037] In the above embodiments, the specific usage method of the device is as follows:

[0038] First step, when in use, place the special tool horizontally on the top of the coke pot, and align the arc-shaped plates at the four corners with the four lifting lugs of the bottom gate of the coke pot vertically one by one;

[0039] Second step, when hoisting the coke pot, connect the steel wire rope to the lifting lug, and the upper part leans against the arc-shaped plate;

[0040] Third step, start the hoisting device to lift the coke pot.

[0041] Make the special tool bear the horizontal tightening force of the steel wire rope to protect the steel structure on the top of the coke pot intact and not damaged.

[0042] There are three coke pot cars (two in use and one in reserve) in a certain coking workshop where this device has been tested. Before the special tool was used, during the overhaul of the coke pot, the steel structure on the outer edge of the top of the coke pot was directly subjected to the horizontal tightening force of the steel wire rope during the hoisting and transfer process, which was very easy to cause deformation or even damage to the steel structure on the top of the coke pot;

[0043] After the special tool is used, during the hoisting and transfer process of the coke pot, the horizontal tightening force of the steel wire rope acts on the special tool, playing a good protective role for the coke pot, which is safe and reliable.

[0045] The hoisting body includes four limiting structures vertically arranged above the lifting lugs.

[0046] The limiting structure is a limiting arc structure welded above the lifting lug, and the height of the limiting arc structure is higher than the edge of the coke pot.
