Corner door type home elevator

Abstract

The invention discloses a corner door type home elevator. The corner door type home elevator comprises a hoistway, a traction machine, a counterweight frame, a counterweight transition wheel, a speed governor, a rope gripper, a car, a landing door, a limiting device, a tensioning device, a buffer, a car frame, traction steel wires, an arrester and a control cabinet. The landing door is arranged between two adjacent surfaces of the hoistway, and the car is movably connected on guide rails of the car; the counterweight frame and counterweight blocks are arranged on counterweight guide rails, and the speed governor and the rope gripper are installed on the top of the hoistway; the limiting device and the tensioning device are installed on the bottom part of the hoistway; the traction machine is arranged on a traction machine pedestal, traction wheels are arranged on the traction machine, the buffer and the arrester are installed on the bottom part of the hoistway, and a tower spring silence structure is arranged in the control cabinet. According to the corner door type home elevator, the structure is optimized, corner space of the car is utilized; the traction machine is installed on the bottom part of the hoistway and inversely assembled, so that the manufacturing cost is low, the installation process is simple, the application scope is wide, and the space utilization rate is improved.

Description

technical field [0001] The invention relates to the field of home elevator technical equipment, in particular to a corner door home elevator. Background technique [0002] Conventional elevators have two door opening methods: single door opening and through door opening. With the development of the national economy, the elevators with the above two door opening methods can no longer meet the design requirements of some specific buildings. Therefore, it is necessary to design an elevator with a new door opening method. To meet market demand; single-door passenger elevators have only one door to enter and exit the car, and through-door passenger elevators have two doors (front and rear doors) to enter and exit the car; [0003] Conventional passenger elevators mostly use a single car door structure, and some passenger or cargo elevators use a through-type double car door structure. There are spaces on the left and right sides of the above-mentioned elevator car. The weight an...

[0002] Conventional elevators have two door opening methods: single door opening and through door opening. With the development of the national economy, the elevators with the above two door opening methods can no longer meet the design requirements of some specific buildings. Therefore, it is necessary to design an elevator with a new door opening method. To meet market demand; single-door passenger elevators have only one door to enter and exit the car, and through-door passenger elevators have two doors (front and rear doors) to enter and exit the car;

[0003] Conventional passenger elevators mostly use a single car door structure, and some passenger or cargo elevators use a through-type double car door structure. There are spaces on the left and right sides of the above-mentioned elevator car. The weight and driving device can also be arranged in a conventional way, and there is only space on the left (or right) and rear side of the elevator with a door opening at a 90° corner, so the elevator guide rails are not convenient to be symmetrically arranged on the left and right sides of the car, which will affect the safety gear device. In addition, the counterweight device and driving device of the elevator cannot be arranged and installed in a conventional way; the usual 90° corner door-opening passenger elevator adopts a hydraulic drive method, and its disadvantages are 1) The requirements for the bending modulus of the guide rail are more conventional The elevator is much larger, and the size of the guide rail and the density of the bracket must be increased, which increases the cost of materials and processing; 2) The static and dynamic friction between the elevator guide shoe and the guide rail increases, and the hydraulic energy of the hydraulic system is converted into mechanical energy. Therefore, The power of the motor is much larger than that of conventional elevators, and the energy consumption increases a lot; 3) Due to the eccentric operation, the elevator running quality is difficult to guarantee, and it is prone to start-up jitter and running vibration, and the comfort is poor

[0004] Due to the unsatisfactory overall structural design of the elevator with the above-mentioned door opening method, the overall occupied space of the household elevator is relatively large, which wastes space resources. Therefore, it is necessary to design an elevator door structure with a small space occupation; a considerable number of residential buildings require right angles (i.e. 90 degree angle) in and out of the car, but the single-door passenger elevator and the through-door passenger elevator cannot meet the requirements of use, thereby bringing inconvenience to life and work
