Detailed description of the invention
In the present embodiment, as shown in Figure 1, a kind of warning safe ladder, comprises both sides ladder beam 1 and the some crosspieces 2 be connected between the ladder beam 1 of both sides form, and is provided with and the level gauge of both sides ladder beam 1 in 60 ° of angles in the inner side of the lower position of both sides ladder beam 1; With both sides ladder beam 1 to refer in 60 ° of angles emergency staircase in a state of use level gauge be 0 °.In concrete enforcement, a pair level gauge can be set respectively on the position apart from 1.3-1.5 rice bottom the ladder beam 1 of both sides, as the left level gauge 4a in Fig. 1 and right level gauge 4b, be convenient to the angle state checking level gauge in any side.As shown in Figure 2, the structure of level gauge is made up of pedestal 10 and the levelling tube 11 being positioned at pedestal 10 inside, liquid (as alcohol) is packaged with in levelling tube 11, and leave a bubble 12, when bubble 12 is placed in centre position, show that level gauge 4 is horizontal, now the angle on emergency staircase and ground is just in time 60 °.Level gauge can measure emergency staircase and ground angulation exactly whether in the security standpoint specified, easy to operate.
The upper position of both sides ladder beam 1 is provided with alarm, alarm is connected with the spring press switch on the top crosspiece 6 be arranged on above the ladder beam 1 of both sides, as shown in Figure 3, in concrete enforcement, a pair alarm (left alarm 3a and right alarm 3b) in parallel relationship and a pair spring press switch (left spring is by the 5a and right spring press switch 5b that compresses switch) can be set respectively on the ladder beam 1 of both sides, concrete connected mode is connected with the static contact interface of left spring by the 5a that compresses switch by the positive pole of battery 9, left spring is connected with the anode interface of left alarm 3a by the moving contact interface of the 5a that compresses switch, the negative pole interface of left alarm 3a is connected with the negative pole interface of right alarm 3b, the anode interface of right alarm 3b is connected with the moving contact interface of right spring press switch 5b, the negative pole interface of right alarm 3b is connected with the negative pole of battery 9, the static contact interface of right spring press switch 5b is connected with the static contact interface of left spring by the 5a that compresses switch.When any one spring press switch is stressed be pressed time, the junction closure of this spring press switch, connects the internal circuit of alarm, starts alarm, gives the alarm.
In the present embodiment, a pair spring press switch is respectively at the two ends apart from crosspiece 6 above ladder 1m place, beam 1 top, both sides, and the position of the 1m at top meets the pertinent regulations of State Grid Corporation of China about ascending operation-using safety.Spring press switch is provided with the grooved pedal 7 of crosspiece 6 above covering, and spring press switch is just in time positioned at the groove of grooved pedal 7, and when being convenient to exert a force on the optional position of grooved pedal 7, spring press switch can sense.
In order to strengthen the steadiness of emergency staircase, in the bottom of both sides ladder beam 1, slipmat 8 can also can be set for improving the stability of ladder.
A kind of mounting method following steps of warning safe ladder are carried out:
Step a, in distance ground level be 1.3m-1.5m both sides ladder beam 1 on an embedded level gauge, and the perpendicular bisector keeping the terraced beam 1 in the horizon of level gauge and both sides is 60 ° of angles; The change of both sides ladder beam 1 gradient with emergency staircase together changes by level gauge, and when level gauge instruction horizontal level, level gauge is just in time parallel to the ground, and now the angle on emergency staircase and ground is just 60 ° of angles.
Step b, above distance 1m place, emergency staircase top, crosspiece 6 is installing a spring press switch 5; Both sides ladder beam 1 near spring press switch 5 installs an alarm;
Step c, up crosspiece 6 install a battery 9, the positive pole of battery 9 is connected with the static contact interface of spring press switch, the moving contact interface of spring press switch is connected with "+" pole interface of alarm, and the "-" pole interface of alarm is connected with the negative pole of battery 9;
Steps d, on spring press switch above place crosspiece 6 and cover above crosspiece 6 position on a grooved pedal 7 is installed.When construction operation personnel set foot on the grooved pedal 7 apart from 1 meter of, ladder top, the spring press switch 5 be positioned on the crosspiece 6 of top is pressed because of the trampling depression of grooved pedal 7, now connects alarm, sends alarm sound, remind operating personnel now to exceed restriction of ascending a height, remind act of violating regulations in time.Grooved pedal 7 can also play rainproof, dustproof effect, and protection spring press switch is not fragile.
