Description

Technical Field

[0001] The invention relates to a household aerial ladder, in particular to an extended-range household aerial ladder. Background Art

[0002] my country is a country with a large population. Currently, there are many elderly people living in duplex buildings. Due to their inconvenient mobility, they need to install vertical elevators or home elevators to assist the elderly with mobility problems. At the same time, the installation of vertical elevators or home elevators for elderly people living alone or disabled people to go up and down the stairs is a large project with high installation price, which is difficult for ordinary families to afford. Therefore, it is necessary to provide a new type of equipment to solve the above problems. Summary of the invention

[0003] In order to solve the problem that it is inconvenient for the elderly or disabled living in duplex buildings to go up and down the stairs, the installation of vertical elevators or home elevators is large in engineering workload and expensive in installation price, the present invention further provides an extended-range home aerial ladder.

[0004] The technical solution adopted by the present invention to solve the above technical problems is:

[0005] A range-extended household ladder comprises a supporting seat, a ladder, a seat supporting sliding assembly, an upward trigger, a downward trigger, a control center, two connecting wires and two DC reduction motors; one DC reduction motor is installed at the top of the ladder, and the other DC reduction motor is installed at the bottom of the ladder; the upward trigger is installed at the top of the ladder near the top DC reduction motor, and the downward trigger is installed at the bottom of the ladder near the bottom DC reduction motor; the supporting seat is fixedly installed on the seat supporting sliding assembly, and the seat supporting sliding assembly is slidably arranged on the ladder; a rope reel is sleeved on the output shaft of each DC reduction motor, and a connecting wire is provided on the rope reel of each DC reduction motor, one end of the connecting wire is fixedly connected to the rope reel of the DC reduction motor, and the other end of the connecting wire is fixedly connected to the seat supporting sliding assembly; the upward trigger, the downward trigger and the two DC reduction motors are fixedly connected to the control center.

[0006] The present invention has the following beneficial effects:

[0007] 1. The ladder 2 is precisely matched, and the height change is performed at the turning point of the ladder 2 to ensure that the seat always passes horizontally from the straight road to the curve. The double-track four-wheel structure is used to clamp the seat, making the operation safe and reliable throughout the process.

[0008] 2. The control center issues an instruction, and the platform operates. When it reaches the designated position, the circuit is powered off and the platform stops operating. After a period of time, the circuit automatically powers on and continues to issue the next instruction. The platform continues to operate according to the instruction until the up trigger 105 or the down trigger 104 is triggered, and the cycle repeats.

[0009] 3. The supporting seat 1 is foldable. When not in use, the pedal and seat can be folded to save space.

[0010] 4. This application helps elderly people or disabled people living alone in duplex buildings who have difficulty walking to go up or down the stairs by using a support seat. This application uses traction power to simplify the power transmission system and thus minimize the production cost. It is simple to operate and easy to use, and its control process is simplified to the maximum extent considering the actual situation of the elderly.

[0011] 5. This application can use the stair area as little as possible to ensure the safety of the work process, and this application can be reused. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] How it works

[0032] The present application uses a triangular seat support sliding assembly 3 in conjunction with a ladder 2 to significantly improve the stability of the structure. When the control panel receives a signal, the upper and lower motors work simultaneously to pull the seat to move. At the end of the track, the triggering normally open / normally closed switch of the upward trigger 105 or the downward trigger 104 resets the control panel to complete the operation process.

[0033] When the present application is used, when the user wants to go upstairs or downstairs, the remote control relay includes a separate remote control relay, a mobile phone remote control relay or a voice relay, and the control is performed through a separate remote control relay, a mobile phone remote control relay or a voice relay, and one of them can be selected according to the use requirements. After issuing the upward command, the manned platform is connected to the traction steel cable, and the motor pulls the entire manned platform upward through the steel cable. During the upward process, the user holds the safety handrail and stands on the standing platform or sits directly on the seat. The manned platform is connected to the traction steel cable, and the motor pulls the entire manned platform upward through the steel cable. When it touches the travel switch of the upward trigger 105, the remote control relay is powered off, the motor is powered off, the platform stops working, and the person is transported to the top position of the ladder 2. After a period of time, the remote control relay is powered on again by the time delay relay, and the control center of the present application is restored to a controllable state. The operation of the downward ladder is implemented through the above control method.
