Description

An assisted stair climbing machine

Technical Field

The utility model relates to the technical field of devices for going up and down a flight of stairs, in particular to an auxiliary stair climbing machine.

Background technique

An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line.

However, due to the economic differences between different regions, some areas still have old buildings. These old buildings are generally low in height and are not equipped with elevators. It takes a lot of physical strength to climb the stairs, especially when transporting items. The user's physical strength can usually be exhausted in a very short time, resulting in inconvenience in use, especially when there are elderly people in the family. In view of this, we propose an assisted stair climbing machine.

Utility Model Content

The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide an auxiliary stair climbing machine which can solve the problem of consuming more physical strength when climbing stairs without an elevator.

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary stair climbing machine, comprising a staircase and two support frames, the two support frames are respectively arranged at the two ends of the stairs, a limit track is fixedly connected between the two support frames, the upper surface of the limit track is fixedly connected with a T-shaped slide rail, the outer surface of the T-shaped slide rail is slidably connected with a T-shaped slider, the upper surface of the T-shaped slider is fixedly connected with a platform, a transmission structure is arranged on the support frame, the upper surface of the platform is fixedly connected with a handrail, limit switches are arranged on the two support frames, and folding seats are arranged on the handrails.

Preferably, a safety belt is provided on the front surface of the armrest, and an emergency switch is provided on the right side surface of the armrest.

Preferably, the transmission structure includes a self-locking motor, which is fixedly connected to the upper surface of the right support frame, and the output end of the self-locking motor is fixedly connected to a sprocket, and the outer surface of the sprocket is transmission-connected to a chain.

Preferably, two support plates are fixedly connected to the upper surface of the support frame on the right side, and a rotating shaft is rotatably connected to one side surface of the two support plates that is adjacent to each other.

Preferably, the outer surface of the rotating shaft is sleeved with a second sprocket, one end of the chain away from the sprocket is transmission-connected to the second sprocket, and the outer surface of the rotating shaft is sleeved with a first winder and a second winder.

Preferably, cables are fixedly connected to the outer surfaces of the first winder and the second winder, a roller is provided on the right surface of the left support frame, and fixed points are respectively provided on the left and right side surfaces of the platform.

Preferably, the cable on the first winder is fixedly connected to a left fixed point of the platform after passing through a roller, and the cable on the second winder is fixedly connected to a right fixed point of the platform.

Preferably, the cable winding directions on the first winder and the second winder are opposite, a brake device is fixedly connected to the lower surface of the platform, the brake device matches the T-shaped slide rail, the emergency switch is electrically connected to the brake device, and the two limit switches are electrically connected to the self-locking motor.

Compared with the prior art, the beneficial effects of the utility model are:

(1) When the user needs to go upstairs, the folding seat is unfolded and the user sits on the folding seat. The platform is then driven to move by the transmission structure, and the T-shaped slider cooperates with the T-shaped slide rail to limit the movement trajectory of the platform. The above structure allows the user to go upstairs or carry items by using the cooperation between the platform and the transmission structure to transport the items or the user to the destination in a more relaxed manner, thereby avoiding the physical exertion caused by repeatedly going up and down the stairs.

(2) For the auxiliary stair climbing machine, the cable is adjusted in direction by the roller and then the platform is pulled to move by the fixed point on the left. At this time, the second winder is used to release the cable to provide space for the movement of the platform. When the platform moves to be flush with the top step, it contacts the limit switch, causing the motor to stop working. When descending, the reverse rotation of the self-locking motor causes the first winder to release the cable and the second winder to reel in the cable. The second winder pulls the fixed point on the right through the cable, thereby causing the platform to descend. When the self-locking motor is fixed, the emergency switch can be used to control the brake device to stop the platform. Through the cooperation of the first winder and the second winder, the platform can descend without the help of gravity to slide down naturally, which can effectively improve the stability of the platform during movement and the safety of users. In addition, the cooperation of the emergency switch and the brake device can further improve the safety of users.
