In-car emergency braking car device capable of being additionally installed

Abstract

The device comprises a car, guide rails are fixedly connected to the two sides of the car, a wedge block is connected to one end of a safety clamp in a clamped mode, a limiting nut is in threaded connection with one end of a pull rod, and a lifting plate is in threaded connection with the end, close to the limiting nut, of the pull rod; lever round steel is welded to one end of the top of the fixing support, a brake plate is fixedly connected to the top of the lever round steel through a positioning stud, a hinge is welded to the other end of the top of the fixing support, one end of the hinge is fixedly connected with one end of a spring, and the other end of the hinge is fixedly connected with the other end of the spring. Existing parts of an elevator are modified, other parts do not need to be replaced, the clamping grooves in the hinges and the clamping hooks on the brake plates moving downwards are interlocked, accidental reset of the brake plates is prevented, effective self-rescue can be achieved, the safety of the elevator is improved, and the safety of personnel is guaranteed.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an emergency braking and stopping car device in a car that can be installed. Background technique [0002] Elevator is a vertical lift powered by a motor, equipped with box-shaped pods, used for multi-storey buildings to take people or carry goods, and there are also stepped types. Fixed lift equipment serving a specified floor. A vertical lift has a car that runs between at least two vertical rows of rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods, regardless of its driving mode. , The elevator is used as a general term for vertical transportation tools in the building. After the old elevator runs for a long time, the elevator will be worn out. If the maintenance is not in place, the elevator will slide, squat and hit the top. In the case of falling or reaching the top, it is impossible to rescue on...

Problems solved by technology

[0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, used for multi-storey buildings to take people or carry goods, there are also steps, and the tread plate is installed on the crawler belt to run continuously, commonly known as escalator or moving walkway, The fixed lifting equipment serving the specified floors. The vertical elevator has a car that runs between at least two vertical rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary regardless of its driving mode. , the elevator is the general term for the vertical transportation means in the building. The old elevator will wear out after running for a long time. In the case of falling or rushing to the top, you cannot effectively save yourself, which will eventually lead to accidents and reduce the safety of the elevator
