Technical Field

[0001] The present invention relates to a track, specifically, a method for adjusting a coke oven track. Background Art

[0002] The coke oven in the coking plant has been in use for a long time. The track of the coal charging car is deformed and settled seriously, so the old track needs to be demolished and a new track needs to be re-laid. The workload of workers for handling is large, the construction speed of the project is slow, the construction time is long, and the mechanical working shift cost is high.

[0003] Therefore, the known methods for laying coke oven tracks have the above-mentioned various inconveniences and problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a safe and reliable method for adjusting a coke oven track.

[0005] To achieve the above purpose, the technical solution of the present invention is as follows: A method for adjusting a coke oven track, characterized by comprising the following steps: a. Fabricate two gantry frames. A chain block is provided hanging down in the middle of the cross beam of each gantry frame. The chain block is provided with two movable hooks for lifting the coke oven track; each gantry frame is provided with walking wheels at the bottom; b. According to the length of each I-beam of the coke oven track, arrange the two gantry frames relatively, so that the two movable hooks clamp on both sides of the upper flange plate of the I-beam to lift the I-beam of the coke oven track; c. The two gantry frames are respectively arranged at both ends of the I-beam of the coke oven track in a form of carrying and lifting, lift the I-beam of the coke oven track, walk to the installation position of the coke oven track, and quickly adjust a section of the track to complete the installation of the coke oven track.

[0006] The method for adjusting the coke oven track of the present invention can also be further realized by adopting the following technical measures.

[0007] In the foregoing method, the wheels are universal wheels.

[0008] In the foregoing method, the cross beam is an H-shaped steel, the material is Q235-B, and the specification is 100x100x6x8.

[0009] In the foregoing method, the rated lifting load of the chain block is ≥2 tons.

[0010] After adopting the above technical solution, the method for adjusting the coke oven track of the present invention has the following advantages: 1. The gantry frame device has a simple structure and is convenient to fabricate; 2. It reduces the workload of workers for handling, reduces the crane cost, can improve the working efficiency of on-site personnel, and speeds up the project progress; 3. The track and the track beam are pre-assembled and adjusted as a whole, which can shorten the construction time and reduce the crane usage cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 Schematic diagram of the gantry structure according to an embodiment of the present invention; Figure 2 Schematic diagram of two gantries lifting the coke oven track according to an embodiment of the present invention, where the track and the track beam are pre-assembled together. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] The present invention will be further described in detail below with reference to the embodiments and their accompanying drawings.

[0013] Embodiment 1 Now please refer to Figure 1 and Figure 2 , the coke oven track adjustment method of the present invention includes the following steps: a. Fabricate two gantries. The bottom is composed of 7-inch and 5-inch universal wheels to form a convenient movable support frame. The cross beam 1 of each gantry is erected using H-shaped steel, and 10-number I-shaped steel is used as the pillar 6. A hanging chain hoist 2 is arranged in the middle of the cross beam 1, and the rated lifting load of the chain hoist is 2 tons. The chain hoist is provided with two movable hooks 4 for lifting the coke oven track; each gantry is provided with walking wheels 7 at the bottom, and the wheels are 5-inch universal wheels.

[0014] b. According to the length of each I-shaped steel of the coke oven track, the two gantries are arranged opposite to each other, so that the two movable hooks clamp on both sides of the upper flange of the I-shaped steel to lift the I-shaped steel of the coke oven track; the track 3 can be pre-assembled with the track beam 5 and adjusted as a whole, which can shorten the construction time and reduce the crane usage cost.

[0015] c. The two gantries are respectively arranged at both ends of the I-shaped steel of the coke oven track in a suspended lifting form, lift the I-shaped steel of the coke oven track, walk to the installation position of the coke oven track, and the worker adjusts the chain hoist to control the horizontal and elevation of the track, quickly adjust a section of the track 3, and complete the installation of the coke oven track. The horizontal transportation and vertical transportation of large machinery are reduced. The cross beam is made of H-shaped steel, with the material of Q235-B and the specification of 100x100x6x8.

[0016] The present invention has substantial features and remarkable technical progress. The coke oven track adjustment method of the present invention can be applied in the coking project of Benxi Iron and Steel, and can quickly adjust a section of the track and the track beam as a whole, which is convenient and fast, reduces the mechanical cost, improves the on-site construction efficiency, has a fast turnover speed, saves labor costs, has no safety hazards, has no adverse effects, speeds up the on-site construction, and ensures the completion of the project on schedule.

[0017] The above embodiments are only for illustrating the present invention and not for limiting the present invention. Those skilled in the relevant technical fields can also make various transformations or changes without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and should be defined by each claim.
