Description

Technical Field

[0001] The utility model relates to the field of coking furnace maintenance, in particular to a large-span lifting platform for coking furnace maintenance. Background Technique

[0002] A coking furnace is a furnace used to refine coke. Modern coking furnaces are composed of a carbonization chamber, a combustion chamber, a regenerator, a flue duct chamber, a furnace top, a flue, etc. The service life of a coking furnace is generally about 25 years, and can reach more than 30 years under the condition of good operation and maintenance. Therefore, regular maintenance of the coking furnace is particularly important.

[0003] At present, the maintenance of coking furnaces is generally carried out by using a lifting platform / lift. However, most of the current lifts are narrow lifts, which have a small space and are not convenient for multi-person maintenance operations. Moreover, this kind of lift only has a lifting function. When it is necessary to move to a different position, the entire body needs to be moved, resulting in troublesome use. Based on this background, the utility model proposes a large-span lifting platform for coking furnace maintenance. While meeting the basic lifting requirements, this kind of lifting platform adopts a platform plate with a large span, providing a larger operating space and enabling multi-person maintenance. Moreover, the platform plate can be translated by a large-span translation component installed inside the supporting frame. When switching the maintenance position, there is no need to move the entire body, making it convenient and fast to use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a large-span lifting platform for coking furnace maintenance to solve the problems raised in the above background technique.

[0019] Please refer to Figures 1-3 , the present utility model provides a technical solution: a large-span lifting platform for coking furnace maintenance, including a chassis (not shown in the figure), a chute bracket 1, a lifting assembly and a large-span translation assembly. Among them, there are two groups of chute brackets 1, and they can be fixed on the chassis through angle codes. The chute bracket 1 is a long bracket with chutes on the inner side, and side plates are connected to the sides of each group of chute brackets 1; the lifting assembly can be installed between the two groups of chute brackets 1. The lifting assembly includes a reduction motor 2, a transmission box 3, a lead screw 4, a lead screw sleeve 5, a moving bracket 6, an X-shaped lifting bracket 7 and a supporting frame 8. Among them, there are two groups of lead screws 4, and one end of each of them is rotatably installed on the side plates on the sides of the chute brackets 1, and the other ends of the two groups of lead screws 4 extend into the transmission box 3; a lead screw sleeve 5 is sleeved on each group of lead screws 4, and a moving bracket 6 is installed on the side of the lead screw sleeve 5. The moving bracket 6 is vertically arranged, and pulleys slidably connected to the chutes are provided at both ends of it.

[0020] In this embodiment, one end of the bottom side of the X-shaped lifting bracket 7 is hinged to the side plate, and the other side of the bottom of the X-shaped lifting bracket 7 is hinged to the moving bracket 6; the reduction motor 2 can be installed on the chassis, and the shaft end of the reduction motor 2 is connected to the transmission box 3 through a transmission shaft.

[0021] In this embodiment, the supporting frame 8 is located on the top side of the X-shaped lifting bracket 7. A chute is provided on the outer side of the supporting frame 8. One side of the top of the X-shaped lifting bracket 7 is hinged to the side of the supporting frame 8, and the other side of its top is slidably connected to the chute on the outside of the supporting frame 8.

[0022] In this embodiment, the large-span translation assembly includes a platform plate 9, a track 10, a rack 11, a gear device 12 and a moving support 13. Among them, the track 10 is located inside the supporting frame 8, and a rack 11 arranged along its length direction is provided on one side of the track 10.
