Examples

The utility model provides a can turn to and remove double ladder, includes support body 5, gyro wheel 7 and drive wheel 8, support body 5 is a support body that forms by hollow aluminum alloy material preparation, support body 5 comprises two parts, and for the convenience of description, two parts are defined as support body A, support body B respectively, and support body A is connected through pivot 501 at top with support body B, and support body A can follow pivot 501 rotation with support body B and open and shut the folding. The frame body 5 is provided with a step 6 for people to move up and down. A connecting platform plate 4 is arranged between the frame body A and the frame body B.

The connecting platform plate 4 is composed of four parts, and any two adjacent parts of the four parts are connected through hinges to form a plane. Among the four portions forming the connecting platform plate 4, the two portions located at the outermost side are connected to the frame body a and the frame body B through the first rotating shaft a and the first rotating shaft B respectively, and the first rotating shaft a and the first rotating shaft B are located on the same plane. When the trestle ladder is folded, four parts of the connecting platform plate 4 are folded in a W shape.

Four support legs at the bottom of the frame body 5 are respectively provided with 4 idler wheels 7, and the idler wheels 7 are connected with the support legs through steering shafts. It should be noted that the steering shaft is a steering shaft connected to a torsion spring, and the initial position of the torsion spring enables the direction of the roller 7 to be forward, and the roller 7 can be driven to return to the initial position after the roller 7 is steered. This structure is achieved by the prior art, so it will not be described in detail.

Still be equipped with two handles 1 on support body A, the throttle device that can twist is partial for the handle of handle 1, the throttle device is through the electricity connect in the driving motor 9 of locating support body 5 bottom to can be through throttle device control driving motor 9's rotational speed. The output shaft of the driving motor 9 is connected to the wheel shaft of the driving wheel 8 positioned at the bottom of the frame body 5 through a transmission system and can drive the driving wheel 8 to rotate. Still be equipped with the battery mount in support body 5 bottom, battery 10 passes through the battery mount to be installed on support body 5 to through connection of electric lines on driving motor 9, for driving motor 9 provides electric power.

The brake pad is arranged on the roller 7 on the support leg A of the frame body and is hidden above the roller 7 and connected with the speed control grab handle 2 on the handle through a stay wire, and the stay wire penetrates through the space in the middle of the material of the frame body 5. Through the contact of the brake pad and the roller 7, the friction force enables the roller 7 not to rotate any more, and therefore the purpose of limiting the rotation of the roller 7 is achieved. The brake pad can be pulled to contact the roller 7 by pinching the speed control handle 2 to the handle 1. The handlebar upper structure can be realized according to the prior art, such as a brake system and a throttle system used by an electric bicycle in the prior art, so that the description is not repeated.

The wheel self-locking switch 3 is arranged below the speed control grab handle 2 on the handle 1, the self-locking switch is a spring buckle, and a male buckle and a female buckle of the spring buckle are respectively positioned on the speed control grab handle 2 and the handle. When the speed control grab handle 2 is pinched until the stay wire is tensioned and the brake pad locking roller 7 rotates, the male buckle and the female buckle can be clamped tightly without manually pressing the speed control grab handle 2. When the moving function of the herringbone ladder needs to be recovered, the male buckle and the female buckle can be separated by loosening the spring buckle, so that the roller 7 is not locked. Such snap-fastener structures are used in a great variety of industries and will not be described in great detail.

When needing to explain, two accuse quick-witted grab handles 2 on two handles 1, be connected to the brake block on the gyro wheel 7 of corresponding one side on the support body A through the stay wire respectively, the purpose of doing so can lock unilateral gyro wheel 7 through holding a tight list accuse quick-witted grab handle 2. At the moment, the driving motor 9 is controlled to drive the driving wheel 8 to roll forwards, and the roller 7 on one side is limited, and the roller 7 on the other side which is not limited rotates faster, so that the frame body 5 can turn towards the side of the locking roller 7.

Between support body A and support body B, the position of 6 marks time with the lower floor still is equipped with connecting plate 11, and connecting plate 11 comprises two parts, connects through the hinge between the two parts to two parts are respectively through second pivot A and second pivot B connect with support body A and support body B on. An avoidance window 1101 is arranged on one part of the connecting plate 11 connected with the frame body A, and when the herringbone ladder is unfolded, a triangular structure formed by the connecting plate 11 and the two parts of the frame body 5 plays a role in stabilizing the structure. When folding, connecting plate 11 is folded for "Λ" type, dodge window 1101 and avoided drive wheel 8 and nearby structure.

The use principle is as follows: when unfolding this double ladder, connecting platform board 4 connects into a plane, and the operating personnel of being convenient for supports the health. An operator sits on the connecting platform plate 4, can hold the two handles 1 with two hands, and drives the driving motor 9 to drive the driving wheel 8 to rotate by twisting the accelerator structure on the handles 1, so that the whole herringbone ladder is driven to move forwards. When the double ladder needs to turn, the single-side speed control grab handle 2 only needs to be pinched, and the brake pad is pulled to be in contact with the roller 7 on the side where the brake pad is located, so that the double ladder turns towards the side where the brake is tight due to the fact that the friction force of the single side is large. After the landing position is reached, the accelerator structure is loosened and the wheel self-locking switch 3 is locked, so that the rollers 7 on two sides are locked, the herringbone ladder does not advance any more, a stable structure is achieved, and an operator can stand on the connecting platform plate 4 to work.

According to the above embodiment, alright realize the utility model discloses well. It is worth to say that, on the premise of the above structural design, in order to solve the same technical problem, even if some insubstantial changes or retouching are made in the utility model, the essence of the adopted technical scheme is still the same as the utility model, so it should be in the protection scope of the utility model.
