It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.
As shown in fig. 1-4, the present invention discloses a walking ascending ladder.
The climbing ladder comprises a first supporting leg 3 and a second supporting leg 10, wherein a certain included angle is formed between the first supporting leg 3 and the second supporting leg 10, specifically, the first supporting leg 3 and the second supporting leg 10 are arranged in a splayed shape, rollers 1 are arranged at the bottoms of the first supporting leg 3 and the second supporting leg 10, and the climbing ladder further comprises a fixed pedal 5, a rotating pedal 8 and a driving leg 9;
wherein, fixed footboard 5 with 3 fixed connection of first supporting leg, be equipped with the first space of trampling on fixed footboard 5, rotatory footboard 8 the inner with fixed footboard 5 the inner articulated connection, just rotatory footboard 8 is located with the articulated position of fixed footboard 5 in the contained angle that forms between first supporting leg 3 and the second supporting leg 10, drive leg 9 top with articulated connection between the 8 bottom surfaces of rotatory footboard, but 9 bottoms free swings of drive leg and can contact with ground, rotatory footboard 8 with the articulated position of drive leg 9 is located in the contained angle that forms between first supporting leg 3 and the second supporting leg 10.
In the above structure of the present invention, the first support leg 3 and the second support leg 10 form the main body structure of the ascending ladder, which can be used for ascending by workers by being placed on the ground. This ladder of ascending a height wholly adopts light-duty aluminum alloy structure, and is whole light firm, and because GIS transformer substation or manufacturing factory building ground all is hardened cement ground, levels relatively, satisfies directly to promote the displacement on this ladder of ascending a height bottom first supporting leg 3 and the second supporting leg 10 again by two gyro wheels, uses laborsavingly, and the motion is nimble. In the invention, the walking of the ascending ladder is realized through the matching of the fixed pedal 5, the rotating pedal 8 and the driving leg 9. The specific working principle is as follows:
in the stable working state of the ascending ladder, as shown in fig. 1 (the dotted line part in the figure is the position state of the driving leg 9 when fixed), the driving leg 9 is inclined and is close to the direction of the second supporting leg 10, at this time, the bottom of the driving leg 9 contacts with the ground, and the aim of locking the ascending ladder is achieved. Under this state, when the operation personnel finishes on the ladder of ascending a height, when turning next working face, stand earlier, one foot tramples first and tramples the space and tramples on fixed footboard 5, and another tiptoe colludes the outer end of rotatory footboard 8, and at this moment the outer end of rotatory footboard 8 upwards rotates, and rotatory footboard 8 drives drive leg 9 and upwards lifts up, and drive leg 9 is free to swing down to being close to first supporting leg 3 direction and swing to roughly and ground vertical position simultaneously, and the face in the scope of drive leg 9 produces relative position. At this time, the standing center of the high-altitude operator moves to the side of the rotating pedal 8, that is, the operator treads the second treading space of the rotating pedal 8, after the rotating pedal 8 is stressed, driving force is generated on the first supporting leg 3 and the second supporting leg 10, so that the ascending ladder can move towards the first supporting leg 10, thus, the rotating pedal 8 is uninterruptedly lifted, the ascending ladder can discontinuously move forwards by treading the rotating pedal 8, like walking, when the rotating pedal 8 is in a horizontal state after reaching an ideal position, the ascending ladder is equivalently locked, the locking is firm and stable, and the high-altitude operation can be carried out at the position. Compared with the traditional ascending ladder structure, the ascending ladder structure has the advantages that the walking of the ascending ladder can be controlled by operating personnel at high altitude through the additionally arranged rotating and moving structure, the structure is simple, the use is convenient, the labor intensity of manpower can be effectively reduced, and the operation efficiency is improved.
In the invention, the first supporting leg 3 and the second supporting leg 10 are respectively provided with a plurality of cross rods 4, and the cross rods 4 are sequentially arranged at certain intervals along the height direction. Through the setting of horizontal pole 4 for the operation personnel can step on horizontal pole 4 and walk to the eminence, and the accessible is trampled the reasonable position of horizontal pole 4 department at the high altitude and is carried out the operation.
In the invention, the fixed pedal 5 is welded on the cross bar 4 arranged on the first support leg 3, and the fixed pedal 5 is horizontally arranged; the outer end of the fixed pedal 5 extends outwards and extends to the outer part 3 of the first supporting leg so as to form the first treading space, and the outer end of the rotating pedal 8 extends outwards and extends to the outer part of the second supporting leg 10 so as to form the second treading space. The outward protruding design of the fixed pedal 5 and the rotating pedal 8 can facilitate the treading and force application of the operating personnel when controlling the walking of the ascending ladder.
Preferably, in order to ensure the connection strength of the fixed pedal 5 of the present invention, the ascending ladder further comprises a connecting rod 6, wherein the upper end of the connecting rod 6 is fixedly connected with the first supporting leg 3, the lower end of the connecting rod 6 is connected with the inner end of the fixed pedal 5, and a triangular support is formed among the first supporting leg 3, the connecting rod 6 and the fixed pedal 5. Through the setting of connecting rod 6, guarantee the intensity of the inner of first supporting leg 3, make it can carry out firm connection with rotatory footboard 8.
Preferably, the driving leg 9 of the present invention has a length designed to satisfy: when the rotating pedal 8 is in a horizontal state, the bottom of the inclined driving leg 9 is positioned at the inner side of the roller 1 of the second supporting leg 10 and is in contact with the roller 1 of the second supporting leg 10, so that the driving leg 9 can block the roller 1 to prevent the climbing ladder from moving, and meanwhile, the rubber pad 11 can be arranged at the bottom of the driving leg 9 to improve the anti-skidding effect. .
Preferably, the ascending ladder of the present invention further comprises a working platform 7, wherein the working platform 7 is fixed on the top of the first support leg 3 and the second support leg 10, the working platform 7 comprises two platforms 12, and a certain gap is arranged between the two platforms 12. The ascending ladder of the invention provides working space for low-level operation and high-level operation. During low-level operation, the user can step on the cross rod 4 standing at a proper height to realize operation. During high-level operation, the worktable can be seated on the table top 12 of the worktable 7 for operation, a certain gap is reserved between the two table tops 12 for movement of operation personnel, and one of the two table tops 12 can also be used for placing tools and the like.
Preferably, reinforcing rods 2 are arranged at the bottoms of the first supporting leg 3 and the second supporting leg 10 of the ladder, two ends of each reinforcing rod 2 are fixedly connected with the first supporting leg 3 and the second supporting leg 10 respectively, and the stability of the ladder is further improved through the reinforcing rods 2.
