Description
Technical Field
The utility model relates to a construction technical field of blast furnace stove outer covering specifically is an assembled cat ladder for business turn over hot-blast furnace stove outer covering.
Background
One of the traditional operating personnel to get in and out of the furnace shell of the blast furnace hot blast stove is to hang two vertical ladders arranged at the inner side and the outer side of the upper edge of the furnace shell, and the other is to weld the vertical ladders on the furnace shell after the assembling and welding of the furnace shell are completed. The first method is to repeatedly use and conveniently remove the crawling ladder, the two crawling ladders are only hung on the upper edge of the furnace shell through the inverted J-shaped hook and are not rigidly connected with the furnace shell body, the crawling ladder shakes greatly when a person goes up and down, particularly when the person crosses the upper edge of the furnace shell, the hand of the person has no stable force point, and the crossing process is dangerous. The second kind has utilized the vertical ladder that the stove outer covering installation was used, and this kind of method is first although vertical ladder and stove outer covering welded fastening, and the climbing process does not have obvious rocking, nevertheless because this vertical ladder welding has safe protection cage, when personnel climbs over the stove outer covering upper edge, safe protection cage caused the hindrance to personnel's shank to the hand impetus is located the stove outer covering upper edge below, influences personnel's safety.
Disclosure of Invention
The utility model aims to overcome the defects and provide an assembled ladder stand which is convenient to use and reliable to fix and is used for passing in and out of a hot blast furnace shell.
In order to achieve the above object, the present invention is realized as follows:
the utility model provides an assembled cat ladder for business turn over hot-blast furnace stove outer covering, includes side bench section, horizontal bench section, the side bench section has two sets, sets up respectively in the both sides of horizontal bench section, and the side bench section passes through the connection piece and the bolt is connected with horizontal bench section, perhaps, side bench section and horizontal bench section welded connection, the side bench section is "A" font and leans out.
The assembled ladder stand for entering and exiting the furnace shell of the hot blast furnace is characterized in that a limiting wheel set is arranged at the bottom of the side ladder section and used for embedding the side ladder section on a supporting beam of the furnace shell assembly platform.
The assembled ladder stand for entering and exiting the shell of the hot blast stove is characterized in that the limiting wheel set comprises a connecting plate, a wheel set retainer, a longitudinal wheel set and a horizontal wheel set, wherein the longitudinal wheel set and the horizontal wheel set are arranged on the wheel set retainer and are respectively contacted with a supporting beam web plate and a flange.
The assembled ladder stand for entering and exiting the shell of the hot blast stove is provided with handrails on the side ladder sections and the horizontal ladder section.
The utility model discloses a personnel provide a safe and reliable's access to inside and outside hot-blast stove outer covering of blast furnace access passageway formula cat ladder, this cat ladder is the oblique cat ladder, and personnel's climbing process is more convenient, laborsaving. This cat ladder welding has safety handle, and personnel scramble the thing hand impetus more reasonable. The furnace shell top is crossed through the small platform on the top of the ladder stand, so that the crossing process is safer. The utility model discloses can dismantle the bolt at top makes the cat ladder divide into two parts, and the two parts move to inside and outside both sides respectively through the spacing round of bottom, lifts by crane the installation for the stove outer covering and vacates the upper portion space, spacing wheelset can not rotate, slope when the split is two parts, and convenient reassembly is in the same place, assembles for next stove outer covering and facilitates.

Detailed Description
The invention is further illustrated by the following specific examples.
As shown in figure 1, the assembled ladder stand for entering and exiting the shell of the hot blast stove is arranged on an H-shaped steel main beam 3 of a splicing platform through a ladder stand 2 and strides over the spliced shell 1 of the hot blast stove of the blast furnace, so that personnel can enter and exit.
As shown in fig. 2, two structural beams 21 are arranged on two sides of the ladder 2, the structural beams 21 can be channel steel, steel plate, i-steel and the like, a step plate 23 is welded between the structural beams 21 on two sides at a height of 200mm, and the step plate 23 can be in a shape of a straight line or a Z shape; a railing 22 is welded on the structural beam 21, and the railing 22 can be made of steel pipes, steel bars and the like; one side of the top of the structural beam 21 is disconnected and connected through a connecting plate 24, and the connecting plate 24 is in a bolt connection mode; the pattern plate 26 is welded on the top of the structural beam 21, and the pattern plate 26 is welded with the right structural beam 21; the structural beam 21 and the bottom of the railing 22 are welded on the base 25; the base 25 is installed on the splicing platform H-shaped steel main beam 3.
As shown in fig. 3 and 4, the base 25 is composed of a bottom plate 251, a roller 252, an anti-roll wheel 253, a guide wheel 254 and an L-shaped steel plate 255; four rollers 252 are arranged below the bottom plate 251, and the rollers 252 are placed on the upper surface of the upper flange of the H-shaped steel main beam 3 of the splicing platform; four L-shaped steel plates 255 are connected below the bottom plate 251, an anti-tilt wheel 253 is arranged on the cross arm of the L-shaped steel plate 255, and a guide wheel 254 is arranged at the end of the L-shaped steel plate 255; the anti-tilt wheel 253 is tightly attached to the lower surface of the upper flange of the H-shaped steel main beam 3 of the assembly platform, the upper flange of the H-shaped steel main beam 3 of the assembly platform is clamped tightly together with the roller 252, and the guide wheel 254 is tightly attached to the web plate of the H-shaped steel main beam 3 of the assembly platform. The bolts at the front connecting plate 24 of the blast furnace hot blast stove shell 1 are lifted and removed, and the two separated parts of the ladder stand 2 are respectively pushed to the two sides, so that the top space is left. After the furnace shell 1 of a blast furnace hot blast stove is hoisted and fixed after the hoisting of the furnace shell 1 of the blast furnace hot blast stove to be treated is finished, the two separated parts of the invention are pushed oppositely, and the connecting plate 24 is installed and the bolt is screwed after the two parts are folded.
