Description

Technical Field

[0001] This utility model relates to the field of chemical equipment maintenance technology, and more specifically, to a tooling for replacing the conveyor belt in a coking dry quenching plant. Background Technology

[0002] In the dry quenching coke production system of the coking industry, GX1 and GX2 belts are key material conveying equipment, undertaking the important function of coke transportation. Their stable operation directly affects production efficiency and safety. Due to long-term exposure to high temperature and dust environment, the belts are prone to wear, aging, and tearing, requiring regular replacement and maintenance to ensure production continuity.

[0003] However, the installation location of GX1 and GX2 belts has significant unique characteristics—they are located in a closed or semi-closed space 5 meters underground, with a narrow working environment, insufficient light, and numerous obstacles such as pipes and equipment in the surrounding area, forming a typical restricted working scenario. In the traditional belt replacement process, after the old and new belts are connected, large equipment such as cranes and forklifts are required to lift the old belt vertically upward from underground, while simultaneously pulling the new belt into place.

[0004] This traditional process has several prominent problems: First, the limited underground space severely restricts the operating radius of cranes and forklifts, resulting in extremely poor equipment operational flexibility and a high risk of collisions with surrounding facilities, posing a serious threat to construction safety. Second, the old conveyor belts need to be lifted vertically, causing concentrated stress on the belts and making them prone to shifting and twisting due to uneven gravity. This requires extensive manual adjustment in real time, which not only wastes manpower but also increases the time spent by personnel in the confined space, raising the risk of accidents. Third, the lifting and traction process requires the coordinated operation of multiple pieces of equipment, with cumbersome procedures and frequent equipment start-ups, shutdowns, and position adjustments, resulting in lengthy replacement operations and severely impacting production plans. Fourth, long-term reliance on large equipment for lifting not only increases equipment rental and energy costs but also exacerbates equipment wear and tear due to frequent lifting operations, indirectly increasing maintenance costs.

[0005] The limitations of the aforementioned traditional processes have resulted in long-term problems for dry quenching belt replacement operations, including high safety risks, large manpower input, low maintenance efficiency, and high costs, becoming a key bottleneck restricting the improvement of the maintenance level of the dry quenching system.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] As shown in the figure, this utility model discloses a belt replacement fixture for dry quenching coking plants, including a belt support 1 and a steering support 2.

[0030] The belt support 1 includes a belt support body and a roller 4. The belt support body includes a frame 5, two sets of support frames 6 and two bearing seats 7. The two sets of support frames 6 are symmetrically installed on the frame 5. Each support frame 6 is topped with a bearing seat mounting plate 8. The bearing seats 7 are installed on the bearing seat mounting plate 8. The two ends of the roller 4 are installed at the two bearing seats 7.

[0031] The steering bracket 2 includes a steering bracket body and a roller 2 9, with the roller 2 9 mounted on top of the steering bracket body;

[0032] The belt support 1 is located in the basement, and a new belt is installed at roller 4.

[0033] When using it, first hoist the belt support 1 with the new belt wound up to the basement (i.e., Figure 1 (At position 1 of the belt support), pull out the new belt connector and place it in the maintenance position. After cutting the old belt, connect the new belt and the old belt connector, then pull out the old belt (located at...) Figure 1 On the right side of the image, in the dry quenching area (not shown), another connector is located from... Figure 1 The belt moves from right to left, to position 2 of the steering bracket, and is then pulled out. At this time, the new belt is also pulled to the maintenance position. Once the old belt has been completely pulled out, the replacement of the new belt is complete.

[0034] Before moving the old belt, cut off the other joint of the old belt and tie it tightly with a steel wire rope. Use a winch or forklift to pull the steel wire rope along the steering bracket 2. Gradually pull out the old belt and cut it off for scrap disposal. At this point, the new belt has been replaced. Both ends of the new belt are longer than the actual length used. Cut the new belt to the appropriate length, make the joint, and vulcanize it.

[0035] In one embodiment of this utility model, frame 5 is a square frame structure. Two connecting rods 10 are installed inside frame 5. The bottom of support frame 6 is mounted on the connecting rods 10. Reinforcing rods 11 are installed on both sides of frame 5, and the reinforcing rods 11 are connected to the top of support frame 6. The connecting rods 10 are for mounting support frame 6. The reinforcing rods 11 are used to strengthen and stabilize support frame 6.

[0036] In one embodiment of this utility model, the support frame 6 includes two support rods 61 and two support rods 62. The bottom of the support rods 62 is installed in the middle of the connecting rod 10. The two support rods 61 are symmetrically arranged on both sides of the support rods 62. The bottom of the support rods 61 is installed on the connecting rod 10.

[0038] In one embodiment of this utility model, the steering bracket body includes a frame 2 12, on which two sets of support frames 2 13 are mounted. A bearing seat 7 is mounted on the top of each set of support frames 2 13, and the two ends of the roller 2 9 are mounted at the two bearing seats 7. The old belt moves from the roller 2 9, serving to tension and change the direction of belt movement, changing the original vertical upward lifting motion of the belt to a translational motion after passing through the roller 2 9.

[0039] In one embodiment of this utility model, two parallel connecting rods 14 are installed at frame 2 12. Support frame 2 13 includes support rod 3 131 and support rod reinforcing rod 132. The support rod reinforcing rod 132 is symmetrically arranged on both sides of support rod 3 131.
