Abstract
The utility model provides a ladder with prevent down function, relates to the electric power technology field, and its structure is for fixed folded sheet (3) that can open that are provided with in chevron shape ladder top, and folded sheet (3) link together two stabilizer blade tops of chevron shape ladder, sets up one between two stabilizer blades in chevron shape ladder middle part and can dismantle locking buckle (2), and the chevron shape ladder sets up four telescopic pressure sensor (1) in the one end that contacts ground. The utility model has the advantages that: the four bottom ends of the ladder are respectively provided with a telescopic pressure sensor, so that the ladder is suitable for uneven ground; the folding baffle is added, so that operators can stand and place light objects when using the herringbone ladder, and safety accidents caused by the fact that the operators take overweight objects can be effectively avoided due to the installation of the pressure sensor and the alarm.
Description
Technical Field
The utility model relates to an electric power tech field especially relates to a ladder with prevent down function.
Background
In the electric power overhaul, a ladder for ascending a height is often needed to overhaul electric power equipment at a higher position. However, when the ladder currently used in the transformer substation is actually used, the following problems exist: the ladder is unstable, and the phenomenon of sideslip is easy to occur when the ladder is used; moreover, the handrails are needed when the ladder is used, so that the working efficiency is reduced and the working efficiency is low; when an ordinary climbing ladder is produced, four points at two ends are in one plane, because of the difference of terrains, the four points are simultaneously in contact with a wall and the ground, three-point contact is easily caused, the other point is suspended, the vertical direction of the axis of the ladder is consistent and difficult, the center of gravity is inconsistent with the axis of the ladder, the ladder is easily inclined, a certain included angle is formed between the ladder and the ground due to the use of the ladder, under the condition of stress, the gravity is decomposed in the horizontal direction, the lower end of the ladder slides outwards, and high-altitude falling casualty accidents are caused.
Disclosure of Invention
To the not enough of prior art, the utility model provides a ladder with prevent down function, its structure is: an openable folding plate (3) is fixedly arranged at the top end of the herringbone ladder, the folding plate (3) connects the top ends of two support legs of the herringbone ladder together, a detachable locking buckle (2) is arranged between the two support legs in the middle of the herringbone ladder, four telescopic pressure sensors (1) are arranged at one end of the herringbone ladder contacting the ground, and a movable anti-slip surface (4) is fixedly arranged at one end of each telescopic pressure sensor (1); the telescopic pressure sensor (1) is structurally characterized in that pressure sensors (8) are arranged at two ends of a balance spring (5), the pressure sensors (8) are connected with a pressure identification control block (7), two three-stage telescopic blocks (6) are arranged between the two pressure sensors (8) around the balance spring (5), and an alarm (9) is arranged at the top end of the telescopic spring (5).
The folding plate (3) connects the top ends of the two support legs of the herringbone ladder together through screws.
And the pressure identification control block (7), the pressure sensor (8) and the alarm (9) are all connected with a power supply.
The detachable locking buckle (2) is shaped like a Chinese character 'hui', one end of the detachable locking buckle (2) is fixed on one leg of the herringbone ladder, and the other end of the detachable locking buckle (2) is detachably hung on the other leg of the herringbone ladder.
The utility model discloses a use method: when the straight ladder is used, firstly, two sections of ladders are beaten into a straight line and then locked, the four contact surfaces of the ladder, the ground and the wall surface are in vertical movable contact design to increase the contact area, the end part of the ladder is in a pressure telescopic type pressure sensor design, the pressure identification control block of the end part can judge according to the pressure values collected by the pressure sensors at the upper end and the lower end of the pressure telescopic device, when the pressure values at the upper end and the lower end are greater than a set value, the normally open contact of the pressure telescopic device is closed, the three-stage telescopic block is made to stretch, and the normally open contact is returned to stop stretching. When the extension length of the pressure expansion piece reaches the maximum length and the normally open contact does not return, the alarm sends out an alarm signal to remind a user of checking.
When the herringbone ladder is used, firstly, two sections of ladders are beaten into the herringbone and then locked, the end part of the ladder is designed by adopting a pressure telescopic type pressure sensor, four end sensors in contact with the ground can judge according to the pressure value set by the sensors, when the pressure value is smaller than the pressure value, the ladder feet at the end part can be properly stretched to adapt to the uneven ground, and the folding plate at the top can be opened so as to stand and place light objects.
The beneficial effects of the utility model reside in that: the four bottom ends of the ladder are respectively provided with a telescopic pressure sensor, so that the ladder is suitable for uneven ground; the folding baffle is added, so that operators can stand and place light objects when using the herringbone ladder, and safety accidents caused by the fact that the operators take overweight objects can be effectively avoided due to the installation of the pressure sensor and the alarm.
