Description

The invention relates to the field of elevator production of residential buildings and can be used in the design of an elevator outside a low-rise residential building.

A known technical solution is provided in U.S. Patent No. 6,032,762

2000 - 03-07, wherein the cylindrical elevator cab door actuator has a linear guide with a pair of levers, a pair of circular cab doors.

According to this technical solution, the cab door spreading device consists of a series of component joints, which reduces the stiffness of the mechanism, accelerates wear, increases operating costs and increases the cab size for the second pair of doors.

Another technical solution is found in Dutch patent NL 1021200 2004-04-01 where the cylindrical elevator cab door actuator has two radial levers with a pivot axis in the center of the cab and a belted electromechanical actuator.

According to this technical solution, the radial levers of the cockpit door actuator with the pivot axis do not have the required dynamic resistance, which accelerates wear and increases operating costs.

The closest analogue to the proposed technical solution is U.S. Patent No. 5,833,331, issued November 11, 1998. In the exterior of the building, two column-type elevator cab movement guides are attached by telescopic supports to the exterior wall of the building. The supports are interconnected in the upper and lower parts and mounted on the building reference site so that a cab with a trolley and an electromechanical actuator mounted below it moves between the guides and the outside wall of the building using four supports, the lower two being actuated wheels. The counterweight lifting parts of the cab are connected to the cab by two ropes and pulleys and move inside the guides. The elevator car trolley and its stops in the building have a hinged door.

The design of this elevator increases its gauge by the width of the cab movement

Telescopic attachment of 3o guides to the building wall is dynamically rigid, electro-mechanical actuation at the bottom of the cab carriage eliminates the possibility of direct exits from the cab to the outside of the residential building, and does not ensure the residential intense transfer of people using electro-mechanical rolling gear for vertical cab lifting.

⁵ the claimed invention aims to provide a lift construction, suitable for low-rise residential buildings and renovation. Another challenge is the design of the elevator car, which can be operated externally to the building, with sliding doors to and from the building with rigid adjusters and heaters. Another challenge is the construction of the elevator, which safely moves people outside the residential building, with cab protection and triple emergency, electromechanical and mechanical braking.

For the technical task of low-rise apartment building construction elevator is resolved using the staircase tarpaukščio sites elevator car stops and the porch pairs released door sublokavus ¹⁵ to the porch, the installation between the building station of the second and third, fourth and fifth floors, following tarpaukščių building sites. The elevator car has two movement guides mounted on the exterior wall of the building, with a top mounted electro-mechanical actuator for transferring the cabin with two pull ropes and pulleys.

²⁰ The technical challenge of operating the elevator cab structure on the outside of the building is solved by installing a circular cylindrical cab body with four movement support trolleys, two pairs of circular cylindrical cab doors that extend to the inside and back of the cab body wall.

Timely activation of the shield-brake is dependent on the deviation of the cab motion transducer reading from the set limit, providing continuous emergency monitoring during elevator operation. At the same time, the shield-brake enclosing the hinged cab door is a means of displacing persons in the event of an emergency door opening, while the column ²⁵ with the axle is a safety device in the event of a cab movement deflection. The panel-brake design allows it to be manufactured as a stand-alone module and delivered to the building, fully assembled and factory tested.
