Description

A kind of gate-type cat ladder warning sign

Technical field

The utility model relates to a kind of alarming device, is specifically related to a kind of warning sign that is used in transmission facility cat ladder place in transformer station.

Background technology

Transformer station is as the intermediate hub of transmission and disttrbution, its inside is provided with a lot of important large scale electrical power units, for fear of ground human factor, the operation of these equipment is caused to interference, reduce the possibility that electric shock accidents occurs, these main equipments are generally all mounted on the higher platform in position.Meanwhile, for the ease of workmen, equipment is carried out to inspection and maintenance, the below of platform is generally all provided with the cat ladder of climbing for workmen.

Because power transformation station equipment is more, complex circuit, non-workmen near time easily there is electric shock accidents, for fear of non-workmen climbing-up equipment privately, in cat ladder porch, be generally all provided with the warning sign that prompting is dangerous or warn, warning sign keeps off at the middle part of ladder, does not have remover just cannot pass through from ladder.

Although this warning sign can stop non-workmen climbing-up equipment privately, but also to workmen, some inconvenience have been brought: when running into the situation of rush repair, first workmen will disassemble warning sign, then also to place in cat ladder porch a nameplate passing through thus for other workmens that point out on the same group, this has just delayed the repairing time to a certain extent, increased workmen's workload, and the warning sign disassembling is not easy to keeping, easily loss or damage.

Utility model content

The utility model technical issues that need to address be to provide a kind of simple to operate, change gate-type cat ladder warning sign easily.

For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows:

A kind of gate-type cat ladder warning sign, comprises quadra, and the width of framework is corresponding with the width of cat ladder, and the height of framework is 3 times or 4 times of distance between the adjacent ladder of cat ladder is stepped on, and four edges of framework are fixed by screws on cat ladder;

The hinged outside surface of side that described framework is gone up along the height direction arranges warning labeling, inside surface and arranges the baffle plate of prompting labeling, the hinged positive stop strip moving for defining baffle also on the side of the hinged baffle plate of framework;

The side that described framework is relative with hinged baffle plate is provided with padlock ring, and on baffle plate, padlock hole is offered in the position of corresponding padlock ring.

Further improvement of the utility model is: described framework is square frame, comprise upper side edge, lower side, limit, left side and right edge, the limit, left side of framework and right edge respectively with the corresponding installation of handrail of cat ladder both sides, the upper side edge of framework and lower side step on the ladder of cat ladder the installation of aliging respectively.

Owing to having adopted technique scheme, the technical progress that the utility model is obtained is as follows:

The utility model is simple in structure, easy to use, and by the framework corresponding with cat ladder width is set on cat ladder, a hinged baffle plate of side of framework, can realize opening and closing of cat ladder passage easily and quickly.

In the utility model, the outside surface of baffle plate posts for pointing out dangerous warning labeling, inside surface to post for pointing out and allows current prompting labeling, can play suggesting effect to workmen, reduces misoperation, increases work efficiency.

On framework of the present utility model, the side relative with hinge point is provided with padlock ring, on baffle plate, the position of corresponding padlock ring is provided with padlock hole, when needs are closed cat ladder passage, only need in padlock ring, articulate a door lock can pin cat ladder, avoid arbitrarily entering of non-workmen, improved security.

On the utility model middle frame, on the side of hinged baffle plate, be also hinged with positive stop strip, when needs keep cat ladder unimpeded for a long time, open completely after baffle plate, only need rotary spacing bar, make positive stop strip block baffle plate, can make cat ladder stay open state, without switch baffle plate repeatedly, improve work efficiency.

Accompanying drawing explanation

Fig. 2: the structural representation in padlock ring and padlock hole;

Wherein: 1. framework, 11. screws, 12. padlock rings, 13. positive stop strips, 2. baffle plate, 21. padlock holes, 31. ladders are stepped on, 32. handrails.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is done further to describe in detail:

A kind of gate-type cat ladder warning sign, as shown in Figure 1, comprises framework 1 and baffle plate 2.

Framework 1 is Quad Sides mount structure, comprises upper side edge, lower side, limit, left side and right edge, and the distance between limit, left side and right edge and the width of cat ladder are corresponding, and the distance between upper side edge and lower side is three times of distance between the adjacent ladder of cat ladder is stepped on.The position of any two side laps of framework 1 is equipped with threaded hole, and framework 1 is fixed on the handrail 32 of cat ladder both sides by the screw 11 coordinating with threaded hole, and the upper side edge of framework 1 and lower side are all stepped on 31 installations of aliging with the ladder of cat ladder.

The width of baffle plate 2 and height are corresponding with framework 1, and baffle plate 2 is hinged on the limit, left side of framework 1 by hinge, and can rotate around hinged position, thereby realize opening and closing of cat ladder.On the limit, left side of framework 1, be also provided with positive stop strip 13, positive stop strip 13 is hinged to the bottom on the limit, left side of framework 1 by screw.Positive stop strip 13 can, around hinged position rotation, for stop the rotation of baffle plate 2 when baffle plate 2 is opened, make baffle plate 2 stay open state.The outside surface of baffle plate 2 posts the warning labeling of " Keep Clear-High Voltage, No climbing ", and inside surface posts the prompting labeling of " upper and lower thus ".

The right edge of framework 1 is provided with padlock ring 12, and on baffle plate 2, padlock hole 21 is offered in the position of corresponding padlock ring 12, and the structure in padlock ring 12 and padlock hole 21 as shown in Figure 2.The width in padlock hole 21 is greater than the width of padlock ring 12, and the length of padlock ring 12 is greater than the thickness of baffle plate 2, and like this, when baffle plate 2 is closed, padlock ring 12 can reach by padlock hole 21 outside of baffle plate 2, so that articulate door lock in padlock ring 12.

When closing cat ladder, forward positive stop strip 13 to a side towards doorframe, then flap shutter 2, makes baffle plate 2 block framework 1, and padlock ring 12 is through padlock hole 21, and now in padlock ring, articulating a door lock can pin cat ladder.On baffle plate 2 outside surfaces, post the warning labeling of " Keep Clear-High Voltage, No climbing ", can warn non-workmen, avoid electric shock accidents.

When needs are opened cat ladder and are carried out plant maintenance, first open the door lock in padlock ring 12, flap shutter 2, exposes the ladder of framework 1 and framework 1 interior cat ladder and steps on 31, can allow workmen pass through from cat ladder.When the time of safeguarding is long, can block baffle plate 2 by rotary spacing bar 13, make baffle plate 2 cannot cover framework 1, can make cat ladder for a long time in open mode.On baffle plate 2 inside surfaces, post the prompting labeling of " upper and lower thus ", can point out the position of workmen's cat ladder, increase work efficiency.
