[0002] The hood of a hood-type furnace is a kind of steel rolling equipment. In order to ensure the production of the hood-type furnace, the heating hood often needs to be replaced and repaired. The heating hood is heavy and needs to be repaired with lifting equipment. A lifting beam is usually used as a lifting tool, but ordinary lifting beams are mostly designed with a symmetrical structure. Since the center of gravity of the heating hood is not at the geometric center of the hood, the lifting center of gravity of the lifting beam does not coincide with the center of gravity of the heating hood, the heating hood deflects, and the lifting center of gravity of the heating hood shifts. After the heating hood is lifted, the center line is tilted, and the tilted heating hood cannot be buckled onto the corresponding furnace platform. The hook head connecting the lifting ring shaft position is inaccurate, which affects the balanced lifting of the lifting ring shaft, affects the lifting work, causes unstable lifting, and creates a huge unsafe factor, posing a safety hazard to surrounding equipment and operators. Summary of the invention

[0003] In order to solve the technical problem of the tilting of the heating hood of a hood-type furnace during lifting, the utility model provides a lifting ring positioning device for the heating hood of a hood-type furnace. The lifting center of gravity of the lifting is relocated by the counterweights of the positioning block, the guide slide plate and the rib plate, and the adjustment of the lifting center of gravity is completed at the position of the lifting ring axis to ensure that the position of the heating hood is accurate each time it is lifted, the center line of the heating hood is vertical and not tilted, the end surface of the hood is balanced, and the heating hood is smoothly buckled onto the corresponding furnace platform. At the same time, the guide slide plate and the rib plate form a hook guide channel to improve the accuracy of the hook head connecting the lifting ring axis, improve the operability of the lifting operation, reduce the surrounding unsafe factors, and improve the safety of surrounding equipment and operators.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] Furthermore, the weight of the right positioning block is 3 to 5 times the weight of the left positioning block.

[0007] Furthermore, the guide slide plate is a trapezoidal plate that is narrow at the top and wide at the bottom.

[0023] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1-Figure 7 As shown, the working principle of a lifting ring positioning device for a hood of a hood-type furnace is as follows: the hook head 12 of the lifting equipment is connected to the concave surface 17 at the center position of the lifting ring shaft 2 of the lifting ring positioning device, and the lifting beam 13 of the lifting ring positioning device is connected to the heating hood. The lifting ring positioning device is used to set counterweights of different weights on both sides of the concave surface 17 at the center of the lifting ring shaft 2, and the lifting center of gravity of the hook head 12 is repositioned and adjusted. After lifting, the center of gravity of the lifting ring positioning device is adjusted to ensure that the center line of the heating hood is vertical and not tilted, and the end surface of the heating hood is horizontal, so that the heating hood is smoothly buckled onto the corresponding furnace platform. The guide slide plate 10 and the rib plate 11 form a guide channel. When the hook head 12 is connected to the lifting ring shaft 2, a guiding effect is provided to the hook head 12 to guide the hook head 12 to accurately hook to the lifting position of the concave surface 17 at the center of the lifting ring shaft 2.

[0025] like Figure 1-Figure 7As shown, a hood-type furnace heating hood lifting ring positioning device comprises a lifting beam 13, a support plate 1 and a lifting ring shaft 2, wherein the lifting beam 13 is connected to the support plate 1 through a steel beam 3, the support plate 1 is symmetrically arranged on both sides of the central concave surface 17 of the lifting ring shaft 2, the steel beam 3 and the support plate 1 are connected by bolts, and an outer vertical plate 4 is arranged between the steel beam 3 and the support plate 1 for reinforcement, and a left positioning block 8 and a right positioning block 9 are arranged at the connection position between the concave surface 17 of the lifting ring shaft 2 and the support plate 1 on both sides, the left positioning block 8 and the right positioning block 8 pass through the lifting ring shaft 2 and are fixed on the inner vertical surface of the support plate 1, the left positioning block 8 and the right positioning block 9 are rectangular parallelepipeds with a through hole 16 at the center position, the left positioning block 8 and the right positioning block 9 pass through the lifting ring shaft 2, and the left end of the left positioning block 8 is welded to the left support plate 1, the right end of the right positioning block 9 is welded to the inner facade of the right side support plate 1, the left positioning block 8 and the right positioning block 9 are made of the same material, the weight of the right positioning block 9 is 3 times the weight of the left positioning block 8, the left positioning block 8 and the right positioning block 9 of unequal weight are both arranged on the lifting ring shaft 2, the lifting ring adjustment device makes a certain counterweight adjustment at the position of the lifting ring shaft 2, the bottom surface of the right positioning block 9 is provided with a rib plate 11 and a guide slide plate 10, the rib plate 11 and the guide slide plate 10 are T-shaped structure, the bottom of the rib plate 11 and the guide slide plate 10 is provided with a right guide plate 7, the rib plate 11, the guide slide plate 10 and the right guide plate 7 are welded to the inner facade of one side support plate 1, the left guide plate 6 is welded on the inner facade of the other side support plate 1 at a symmetrical position of the right guide plate 7, The T-shaped structure composed of the rib plate 11 and the guide plate 10 forms a narrow upper and wide lower space slope between the right support plate 1 and the eye shaft 2. This slope space is the guide channel for the hook head. When the hook head 12 is lifted and connected to the eye shaft 2, the narrow upper and wide lower guide channel formed between the guide plate 10 and the rib plate 11 can easily guide the hook head 12 to the lifting position of the concave surface 17 of the center of the eye shaft 2, so that the hook head 12 can be accurately hooked to the center of the eye shaft 2, avoiding the hook head 12 from failing to lift to the specified position and causing the cover to tilt, thereby improving the accuracy of the connection of the hook head 12, improving the lifting capacity of the hook head 12, improving the lifting installation efficiency, and improving the lifting operation rate. The guide plate 10 and the rib plate 11 are also between the eye shaft 2 and the support plate 1 The counterweight was readjusted again, the guide slide plate 10 and the rib plate 11 were only set under the right positioning plate 9, the counterweight continued to increase to the right, and the lifting center of gravity of the hook head 12 was offset to the direction of the T-shaped structure on the right support plate 1. By adding eccentric counterweights to the right side of the hook head of the right support plate 1 and the lifting ring shaft 2, the lifting center of gravity of the lifting ring positioning device was repositioned. Due to the internal structure of the heating hood of the hood-type furnace, the center of gravity of the heating hood and the geometric center of the heating hood are inconsistent. The conventional lifting of the heating hood is seriously eccentric. The lifting center of gravity is adjusted by the lifting ring positioning device, and the lifting center of gravity of the heating hood after lifting is adjusted to ensure that the geometric center line of the heating hood is always vertical, the heating hood body remains balanced, and the heating hood is smoothly buckled onto the corresponding furnace platform.
