Description

A kind of Portable telescopic A-ladder

Technical field

This utility model relates to ladder field, particularly relates to a kind of Portable telescopic A-ladder.

Background technology

Popularization and application along with bench type distribution transformer, and the stand distribution transforming typical design solution being continually changing, daily O&M and table meter periodically core to platform based distribution transformer are copied and are made troubles, the low-tension switch cabinet height of general platform based distribution transformer is at about 2 meters, carry out having a power failure send again copy with table meter core time, personnel need belt length ladder to climb.The ladder volume so used is relatively big, carries inconvenience, and stores and take up space very much.

Summary of the invention

In order to overcome above-mentioned deficiency of the prior art, the purpose of this utility model is, it is provided that a kind of Portable telescopic A-ladder, including: cat ladder one, cat ladder two and cushion block；The end of cat ladder one and cat ladder two is connected through the hinge composition double ladder；

Be provided with in the upper end of double ladder the pulley for lifting article and with pulley with the use of halliard；Four dismountable universal wheels are set on cat ladder two；

Each step upper end of cat ladder one is provided with photoelectric sensor, and the top of cat ladder one is provided with LED, voice broadcast module and the battery suitable with photoelectric sensor quantity；

Battery is for powering to photoelectric sensor and LED；

Each photoelectric sensor is individually connected with one of them LED, when photoelectric sensor triggers sensing, bright with the LED that this photoelectric sensor is connected；

Described voice broadcast module electrically connects with photoelectric sensor, and described voice broadcast module is for reporting the step corresponding to sensed photoelectric sensor.

Preferably, the angle of cat ladder one and cat ladder two is respectively equipped with anti-skid protecting cover.

Preferably, the lower end of cat ladder one and cat ladder two is provided with expansion link.

Preferably, being provided with a shelf in the upper end of double ladder, inner side with cat ladder one and cat ladder two respectively, the two ends of described shelf is connected.

Preferably, cushion block includes: convex strip, two telescopic bands and be separately positioned on the Magnet on two telescopic bands；

Convex strip is provided with top and two shoulders being connected with the both sides at top；

Article two, telescopic band correspondence respectively is connected with two shoulders of convex strip.

As can be seen from the above technical solutions, this utility model has the advantage that

The double ladder that this utility model provides is scalable, it is simple to carry, and by arranging flexible rack, processes outside the interim placing articles of convenient working personnel, moreover it is possible to play the effect limiting double ladder expanded angle, it is ensured that the safe handling of ladder.

Accompanying drawing explanation

In order to be illustrated more clearly that the technical solution of the utility model, the accompanying drawing used required in describing will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the structure chart of Portable telescopic A-ladder；

Fig. 2 is the structure chart of cushion block.

Detailed description of the invention

For making utility model purpose of the present utility model, feature, the advantage can be the most obvious and understandable; specific embodiment and accompanying drawing will be used below; the technical scheme of this utility model protection is clearly and completely described; obviously; the embodiments described below are only a part of embodiment of this utility model, and not all embodiment.Based on the embodiment in this patent, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this patent protection.

The present embodiment provides a kind of Portable telescopic A-ladder, as it is shown in figure 1, include: cat ladder 1, cat ladder 22 and cushion block 9；The end of cat ladder 1 and the end of cat ladder 22 are connected through the hinge composition double ladder；

Be provided with in the upper end of double ladder the pulley 3 for lifting article and with pulley 3 with the use of halliard 7；Four dismountable universal wheels 8 are set on cat ladder 22；

Each step upper end of cat ladder 1 is provided with photoelectric sensor 11, and the top of cat ladder 1 is provided with LED 12, voice broadcast module and the battery suitable with photoelectric sensor 11 quantity；

Battery is for powering to photoelectric sensor 11 and LED 12；

Each photoelectric sensor 11 is individually connected with one of them LED 12, when photoelectric sensor 11 triggers sensing, and the LED bright 12 being connected with this photoelectric sensor 11；

Described voice broadcast module electrically connects with photoelectric sensor 11, and described voice broadcast module is for reporting the step corresponding to sensed photoelectric sensor 11.

So personnel are when cat ladder, it can be seen that LED is bright, it is judged that oneself climb to which floor step.And report the step corresponding to sensed photoelectric sensor 11 by voice broadcast module, the most sufficiently understand the step at oneself place, improve degree of safety.

Anti-skid protecting cover 5 it is respectively equipped with on the angle of cat ladder 1 and cat ladder 22.The lower end of cat ladder 1 and cat ladder 22 is provided with expansion link 4.

Be provided with a shelf 6 in the upper end of double ladder, inner side with cat ladder 1 and cat ladder 22 respectively, the two ends of described shelf 6 is connected.
