[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0028] According to a specific embodiment of the present invention, Figure 1-3 As shown, the present invention provides a reinforced smoke guide track for coke oven renovation. After the furnace roof of the coke oven renovation section is removed, the smoke guide track 1 loses its supporting foundation, and the smoke guide track 1 of the renovation section is in a suspended state. If the smoke guide track 1 is to be used as a running track for a lifting device, the smoke guide track 1 needs to be reinforced.

[0029] The smoke guide vehicle track reinforcement device comprises a smoke guide vehicle track 1, a main beam and a cross beam. Two smoke guide vehicle tracks 1 are provided, and the smoke guide vehicle tracks 1 are used as guide rails for the movement of lifting equipment; four main beams are provided, and a main beam is provided on the left and right sides of each smoke guide vehicle track 1, and the two ends of the main beam are respectively erected on the top of the unrenovated coke oven to serve as a load-bearing beam.

[0030] There are multiple cross beams, all of which are erected between two main beams. The multiple cross beams are arranged in parallel along the extension direction of the smoke guide vehicle track. The smoke guide vehicle track 1 is erected on the multiple cross beams, that is, the multiple cross beams are erected in parallel along the extension direction of the smoke guide vehicle track between the main beams on the left and right sides of the smoke guide vehicle track. Multiple cross beams are erected side by side between the two main beams, so that the main beams and the cross beams form a support frame, and the two ends of the support frame are erected on the top of the coke oven that has not been dismantled. The smoke guide vehicle track 1 is laid on the cross beam, so that the smoke guide vehicle track 1 in a suspended state is supported, which is convenient for the use of the smoke guide vehicle track 1.

[0031] The main beam is an H-shaped steel 2, and both ends of the H-shaped steel 2 are fixed on the top of the coke oven that has not been dismantled; the H-shaped steel 2 serves as the main load-bearing beam to provide support for the smoke guide vehicle track 1. The H-shaped steel 2 has high structural strength and a relatively stable structure, and can ensure the support strength of the smoke guide vehicle track 1. In other embodiments, the main beam can also be a channel steel, the opening of the channel steel is arranged toward the smoke guide vehicle track 1, and the crossbeam is erected on the side below the channel steel.

[0032] The H-shaped steel 2 includes a lower wing plate 23, a steel web 22 and a top plate 21, and the steel web 22 is perpendicular to the lower wing plate 23 and the top plate 21. The crossbeam is a channel steel 3, which has a high structural strength and can meet the support requirements of the smoke guide vehicle track 1; the opening of the channel steel 3 faces downward, and the two ends of the channel steel 3 are respectively welded to the lower wing plate 23 of the H-shaped steel 2. That is, the bottom surface of the channel steel 3 is in contact with the smoke guide vehicle track 1, ensuring that there is sufficient contact area between the channel steel 3 and the smoke guide vehicle track 1, so that the smoke guide vehicle track 1 can be effectively supported. The bottom surface of the lower wing plate of the H-shaped steel is in contact with the top surface of the coke oven that has not been dismantled. The lower wing plate can be welded to the top surface of the coke oven, or it can be fastened to the top surface of the coke oven by bolts.

[0033] The spacing between two adjacent channel steels 3 ranges from 0.8 to 1 m (0.8 m, 0.9 m, and 1 m can be selected). In this embodiment, the cross beam is a channel steel. In other embodiments, the cross beam can be other steel sections, such as C-shaped steel, square steel, and the like.

[0034] A first angle steel 4 is welded between the steel web 22 of the H-shaped steel 2 and the channel steel 3, and a triangular structure is formed between the first angle steel 4, the H-shaped steel 2 and the channel steel 3. The provision of the first angle steel 4 can strengthen the structural strength of the main beam and the cross beam, making the frame structure formed between the main beam and the cross beam more stable; although the first angle steel 4 does not directly reinforce the smoke guide vehicle track 1, a reinforced triangular structure is formed between the first angle steel 4 and the main beam and the cross beam, thereby forming a three-dimensional reinforcement for the smoke guide vehicle track 1, so that the smoke guide vehicle track 1 will not overturn.

[0035] The smoke guide vehicle track reinforcement device also includes a plurality of reinforcement structures, which are arranged between two H-shaped steels (i.e., main beams) between two smoke guide vehicle tracks 1 along the extension direction of the smoke guide vehicle track 1. The distance between two adjacent reinforcement structures ranges from 3 to 5 m (3 m, 3.5 m, 4 m, 5 m, etc. can be selected).

[0036] The reinforcement structure includes two steel pipes 6, which are parallel to each other. A plurality of angle steels 7 are welded between the two steel pipes 6, and a triangular structure is formed between each two adjacent angle steels 7 and one of the steel pipes 6, thereby ensuring that the reinforcement structure itself has sufficient structural strength. In other embodiments, the reinforcement structure may also be made of channel steel, H-shaped steel, truss structure, etc.

[0037] A reinforcement structure is arranged between the two H-shaped steels between the two smoke guide vehicle tracks 1, so that the entire smoke guide vehicle track reinforcement device forms an integral structure. The entire smoke guide vehicle track reinforcement device forms a frame structure erected on the furnace top for dismantling. The entire structure has better structural strength, so that the lifting equipment on the smoke guide vehicle track can move more smoothly.

[0038] The lifting equipment is a gantry crane 5. After the smoke guide vehicle track 1 is reinforced, the gantry crane 5 is installed. First, the gantry crane 5 is assembled on the ground, and then the assembled gantry crane 5 is hoisted onto the smoke guide vehicle track 1 by a crane, and finally debugged and operated.

[0039] The gantry crane 5 includes a load-bearing main beam 51 and two legs 52 , and the two legs 52 are arranged at both ends of the load-bearing main beam 51 ; rollers are arranged on the two legs 52 , and the two legs are installed on the smoke guide vehicle track 1 , and the gantry crane 5 is displaced along the smoke guide vehicle track 1 through the rollers.

[0040] In summary, the technical solution of the reinforced smoke guide track for coke oven renovation provided by the present invention can realize the installation of a gantry crane on the smoke guide track by reinforcing the existing suspended smoke guide track, which is suitable for horizontal and vertical transportation of materials in a narrow space of coke oven renovation, has high transportation efficiency, and low manufacturing, installation and use costs. Moreover, the reinforced smoke guide track is easy to operate, reasonably priced, and easy to use, which can greatly reduce the labor intensity of workers carrying materials during furnace construction and save construction time.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
