Technical Field

The invention relates to a triangular elevator, which is particularly suitable for changing a step ladder into an inclined plane elevator.

Background

Most of the existing inclined plane elevators are designed on large occasions, and have the defects of heavy body size, high manufacturing cost, incapability of randomly expanding length, incapability of being suitable for step ladder transformation and the like.

Disclosure of Invention

The invention relates to a triangular elevator which is capable of realizing cascade connection and solves the technical problems that an inclined plane elevator is insufficient in miniaturization, a step ladder elevator is transformed and the old people are difficult to climb the step ladder.

The triangular elevator is realized by the following design:

preferably, the triangular elevator consists of a frame, a tubular motor, a transmission gear, an unpowered carrier roller, a conveyor belt and a side cover plate.

Preferably, the triangular elevator is designed into a triangular body and can be embedded into the step, and after the plurality of triangular elevators are connected in series, the surface of the step can be paved into a flat inclined plane.

Preferably, the tubular motor is a mature 220V single-phase asynchronous tubular motor on the market, a proper torque is selected according to the load, the tubular motor has a self-locking function and is not limited, the tubular motor is electrified and rotates, and the forward rotation and the reverse rotation of the tubular motor are controlled through two groups of power supply connecting wires.

Preferably, a plurality of transmission gears are nested on the surface of the tubular motor, and the transmission gears are meshed with the convex patterns on the inner wall of the conveyor belt to drive the conveyor belt to move around along the unpowered carrier roller and the motor.

Preferably, the inclined surface of the frame is designed with a plurality of unpowered rollers with convex teeth on the surfaces, and the rollers can support the weight of a user and also help the conveyor belt to rotate.

Preferably, an openable side cover plate is designed on one side of the triangular elevator, and a tubular motor head is placed in the space in the side cover plate, so that wiring of the motor head and arrangement of a power line are facilitated.

The working principle and the working process of the triangular elevator are as follows:

the tubular motor is arranged in the middle of the frame (figure 15), the unpowered carrier roller is arranged on the inclined plane of the frame, and the conveyor belt is sleeved on the unpowered carrier roller group and the tubular motor gear group (figure 8), so that the convex teeth on the inner side of the conveyor belt are meshed with the teeth on the surfaces of the unpowered carrier roller and the transmission gear on the tubular motor. After the tubular motor is electrified to rotate forward, the conveying belt is driven to rotate along the unpowered carrier roller and the motor, at the moment, people or objects stand on the conveying belt, the conveying belt conveys the people to the previous stage, and the previous stage continuously relays to realize the upward conveying of the triangular elevator; on the contrary, the tubular motor is electrified and reversely rotated, so that the downward conveying of the triangular elevator can be realized. The two automatic delay (such as one minute) power-off switches are matched, and the tubular motors of the triangular elevators are connected in parallel on the forward and reverse adapter connectors, wherein one control the forward rotation to go upwards, and the other control the reverse rotation to go downwards.

When an automatic delay (such as one minute) power-off up/down switch is pressed, the triangular elevator conveyor belt starts to rotate, a user stands on the conveyor belt, the conveyor belt rotates up/down to send the user to the triangular elevator of an adjacent rank array, the steps are repeated until the user is sent to a high place from a low place of a step or sent to a low place from a high place of the step, the power is automatically cut off after one minute, and the triangular elevator enters a power-off standby state.

In the design and embodiment disclosed here, items not explicitly disclosed, such as operating conditions and operating conditions, various parameters, and the size, weight, volume, and the like of the components, are assumed to be values that can be easily assumed by a person skilled in the art without departing from the scope of the general practice of the person skilled in the art.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and its concept within the technical scope of the present invention.

The invention has the following beneficial effects:

1. the design of the triangle body is adopted, and the step can be perfectly embedded into the step of the step ladder.

2. A plurality of triangular elevators can be cascaded into a group for use and can be adapted to the steps with various stage lengths.

3. The triangle elevator is suitable for elevator transformation of the stairway building and elevator transformation of public steps, and is convenient for old people, children and pregnant women to go up the stairway.

4. The triangular elevator is used for changing the elevator from a stair building to an elevator, does not need to transform a corridor or civil engineering an elevator shaft, has no requirement on the stairway steps, and is friendly to low-rise residents.

5. The triangular elevator is used for changing the elevator from a step building to an elevator, can change the elevator from the step building from any floor, and is suitable for wide application in the aspects of changing the elevator from the step building with any floor height, transforming the elevator from a low-floor elevator and the like.

6. The triangle body elevator is used for the step building to change the elevator, only need occupy half width of step can (as shown in fig. 23), when realizing that the step changes the elevator, do not influence the original function of step, can realize that triangle body elevator and step are coexistent.

7. The triangular elevator is simple in structure, convenient to install, maintain and use and low in use and maintenance cost.

8. The inclined plane of triangle body elevator is smooth characteristic, makes personnel can stand and use the elevator on the inclined plane, also can squat and sit and use the elevator on the inclined plane, still can reform transform the step into goods transfer passage fast.

9. When a plurality of triangular bodies are connected into a group for use, a certain stage fails and does not influence the use of the whole group.

10. When a plurality of triangular bodies are connected into a group for use, the start-stop control can be realized only by controlling the on-off of the power supply of the group; the automatic time-delay power-off switch is matched with a mature automatic time-delay power-off switch on the market, so that the whole set of the triangular elevator can be automatically powered off (for example, for one minute) after working for a certain time, and the electric energy is saved to the maximum extent.
