Abstract
Provided is a protection door capable of being opened and closed automatically along with rising and falling of an elevator. The protection door is composed of two hollow door posts and a plurality of reinforcing steel bars, wherein the two hollow door posts and the reinforcing steel bars are welded. The width of the protection door is equal to or slightly smaller than that of a platform passageway. Two protruded top pieces are arranged on the protection doors. Each protruded top piece is formed by a vertical iron plate, a horizontal iron plate, a left iron plate and a right iron plate which are welded. The vertical iron plates are welded between the reinforcing steel bars and the hollow door posts, the horizontal iron plates are welded to the vertical iron plates, the left iron plates and the right iron plates are welded to the two sides of the vertical iron plates, and the lower portions of the left iron plates and the lower portions of right iron plates are welded to the horizontal iron plates. Fixing posts are fixed to the platform passageway, the radii of the fixing posts are smaller than the inner diameters of the hollow door posts, and the fixing posts are sleeved by the hollow door posts. The protection door can move up and down on rails formed by the two fixing posts, fixing post rails are parallel to elevator rails, and the protruded top pieces are arranged in lifting rails of the elevator.
Description
Technical field
The utility model relates to a kind of protective door with companion ladder lifting automatic switch.
Background technology
The 4m of smeltery
2blast furnace have tens meters high, the feeding mouth of blast furnace is the blast furnace furnace roof place at tens meters high, therefore will first material will be transported to tens meters of high positions toward reinforced in blast furnace, this will use easy companion ladder, and this kind of companion ladder is also common on short building ground.Conventionally a platform can be built in order to deposit a small amount of material by factory at air blast furnace roof place, half meter of high guard rail can be equipped with in other positions of platform surrounding, but the platform gangway at companion ladder does not generally have guard rail, this is because workman need repeatedly pass in and out companion ladder transport weight while doing things, there is guard rail inconvenience also to increase to a certain extent workman's labour intensity, and do not have guard rail just to have potential safety hazard; Some factory is in order to ensure safety of workers, in platform outlet, chain connection fixing protective door of keeper on one side in that one side is housed, when use, open that to be finished rear bolt tight, but fact proved, this kind of protective door also do not eliminate safe hidden trouble completely, but more serious while having an accident in the time that workman does not fasten because of carelessness, and because workman need do more work, need to pay attention to protective door and whether shut and take a lot of trouble that god increases, labour intensity more.
Summary of the invention
There is the problem of potential safety hazard in order to overcome existing companion ladder eminence platform gangway place.The utility model provides a kind of protective door with companion ladder lifting automatic switch.In the time that companion ladder is raised to platform gangway, door and then companion ladder rises and opens, and in the time that companion ladder lands, door can and then drop on platform gangway place and close.
In order to achieve the above object, to solve the technical scheme that its technical matters adopts be following design to the utility model:
Protective door is welded by two hollow door pillars and some reinforcing bars, protective door and platform gangway are wide or slightly narrow, on protective door, there are two blocks of outstanding top flats, outstanding top flat forms by erecting iron plate, horizontal iron plate, left iron plate, the welding of right iron plate, a perpendicular iron plate is welded between reinforcing bar and hollow door pillar, horizontal iron plate is welded on perpendicular iron plate above, and left and right iron plate is welded on the both sides of perpendicular iron plate, and weld mutually with horizontal iron plate left and right iron plate below.Fixed leg is fixed on platform gangway place, the radius of fixed leg is less than the internal diameter of hollow door pillar, and hollow door column sleeve, on fixed leg, moves up and down on the track that protective door can form at two fixed legs, fixed leg track and companion ladder parallel track, outstanding top flat is in the fluctuating orbit of companion ladder.
When companion ladder rises during near platform gangway place, the top of companion ladder contact with the outstanding top flat on protective door, if now the companion ladder protective door that continues to rise can be followed companion ladder upward movement, in the time of companion ladder arrival platform exit, opens; In the time that companion ladder declines, protective door finally falls within platform exit along with companion ladder drops to, and door is closed.
Effect of the present utility model is: protective door can be with companion ladder lifting automatic switch, easy to use, does not need workman's operating switch door, has avoided situation about having an accident because of human negligence, has improved the working environment of workers, improves the safety case of workman's work.

Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is a kind of front view of the protective door with companion ladder lifting automatic switch.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the birds-eye view of Fig. 2.
In figure
1, hollow door pillar 2, outstanding top flat 3, fixed leg.
Detailed description of the invention
Protective door is welded by two hollow door pillars 1 and some reinforcing bars, protective door and platform gangway are wide or slightly narrow, on protective door, there are two blocks of outstanding top flats 2, outstanding top flat 2 is made up of perpendicular iron plate, horizontal iron plate, left iron plate, the welding of right iron plate, a perpendicular iron plate is welded between reinforcing bar and hollow door pillar 1 as shown in Figure 1, horizontal iron plate is welded on perpendicular iron plate above, and left and right iron plate is welded on the both sides of perpendicular iron plate, and weld mutually with horizontal iron plate left and right iron plate below.Fixed leg 3 is fixed on platform gangway place, the radius of fixed leg 3 is less than the internal diameter of hollow door pillar 1, hollow door pillar 1 is enclosed within on fixed leg 3, on the track that protective door can form at two fixed legs 3, move up and down, fixed leg 3 tracks and companion ladder parallel track, outstanding top flat 2 is in the fluctuating orbit of companion ladder.
When companion ladder rises during near platform gangway place, the top of companion ladder contacts with the outstanding top flat 2 on protective door, if now the companion ladder protective door that continues to rise can be followed companion ladder upward movement, in the time that companion ladder arrives platform exit, opens; In the time that companion ladder declines, protective door finally falls within platform exit along with companion ladder drops to, and door is closed.
