Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste heat boiler maintenance technology, specifically a detachable maintenance guide rail device. Background Technology
[0002] With societal development, people have increasingly higher demands for environmental beautification. As a large industrial piece of equipment, boilers have also seen a new requirement for aesthetically pleasing design. Conventional waste heat boilers typically have a maintenance electric / manual hoist on the steam drum platform at a height of about 30 meters. The hoist's guide rail extends beyond the boiler platform, which, besides affecting aesthetics, also poses certain risks due to the prolonged extension of the rail. Summary of the Invention
[0003] To solve the above-mentioned technical problems, this utility model provides a detachable maintenance guide rail device, which can be easily disassembled when not in use, thus satisfying the aesthetic requirements and reducing safety hazards.
[0004] The technical solution is as follows: A detachable maintenance guide rail device includes a fixed steel frame, which includes an upper crossbeam steel frame and a lower fixed guide rail. The lower fixed guide rail is connected to one end of a detachable guide rail via a bolted connection structure. The bolted connection structure includes a first bolt, a second bolt, an upper connecting plate, a first pad welded to the lower fixed guide rail, and a second pad welded to the detachable guide rail. The first bolt passes through the upper connecting plate, the first pad, and the upper end of the lower fixed guide rail and is locked with a first nut. The second bolt passes through the upper connecting plate, the second pad, and the upper end of the detachable guide rail and is locked with a second nut. An oblique reinforcing steel is welded onto the detachable guide rail. Vertical connecting steel is welded to both the detachable guide rail and the oblique reinforcing steel. The vertical connecting steel is connected to the upper crossbeam steel frame via a bolted connection structure two. The bolted connection structure two includes a third bolt and a third pad welded to the vertical connecting steel. The third bolt passes through the lower end of the upper crossbeam steel frame and the third pad and is locked with a third nut.
[0005] A further feature is that the first pad and the second pad are two abutting horizontal plates, and the upper connecting plate is composed of two abutting horizontal vertical plates, with two holes provided on each of the horizontal plates and the horizontal vertical plates; The third pad has four holes.
[0006] By adopting this utility model, the detachable guide rail is connected to the upper crossbeam steel frame and the lower fixed guide rail by bolt connection. When it is not in use, it can be easily removed, reducing the risk of falling and improving aesthetics and safety. Attached Figure Description

Detailed Implementation
[0008] See Figures 1-6 As shown, a detachable maintenance guide rail device includes a fixed steel frame, which comprises an upper crossbeam steel frame 1 and a lower fixed guide rail 2. The lower fixed guide rail 2 is connected to one end of a detachable guide rail 4 via a bolt connection structure 3. The bolt connection structure 3 includes a first bolt 3-1, a second bolt 3-2, an upper connecting plate 3-3, a first pad 3-4 welded to the lower fixed guide rail 2, and a second pad 3-5 welded to the detachable guide rail 4. The first bolt 3-1 passes through the upper connecting plate 3-3, the first pad 3-4, and the upper end of the lower fixed guide rail 2 and is locked by a first nut. The second bolt 3-2 passes through the upper connecting plate 3-3, the second pad 3-5, and the upper end of the detachable guide rail 4 and is locked by a second nut. The first pad 3-4 and the second pad 3-5 are two abutting horizontal plates. The upper connecting plate 3-3 is composed of two abutting horizontal vertical plates. Each horizontal plate and each horizontal vertical plate has two holes. By using the horizontal and vertical arrangement, a reliable and stable connection is achieved.
[0009] A diagonal reinforcing steel 6 is welded onto the detachable guide rail 4. A vertical connecting steel 5 is welded onto the detachable guide rail 4 and the vertical reinforcing steel 6. The vertical connecting steel 5 is connected to the upper crossbeam steel frame 1 through a bolt connection structure 2 7. The bolt connection structure 2 7 includes a third bolt 7-1 and a third pad 7-2 welded to the vertical connecting steel 5. The third bolt 7-1 passes through the lower end of the upper crossbeam steel frame 1 and the third pad 7-2 and is locked by a third nut. Four holes are opened on the third pad. Bolts are connected to both sides of the upper crossbeam steel frame 1 and both sides of the vertical connecting steel 5 to ensure connection stability.
[0010] The vertical connecting steel 5 has a reinforcing plate 8 welded to the side near the bolted connection structure 3.
