Embodiment Construction

[0020] Specific embodiments of the present invention will be described below.

[0021] like figure 1 , figure 2 , image 3 and Figure 4 As shown, a home elevator pit maintenance safety protection device includes a jack rod mounting bracket 1, and one side of the jack rod mounting bracket 1 is fixed on a guide rail by a bolt 10 and a pressure guide plate 11. The other side of the ejector rod mounting bracket 1 is fixedly connected to the angle steel 8 through the connecting plate 9 . The connection between the above-mentioned connecting angle steel 8 and the connecting plate 9 is "Π" shape. One end of the push rod connecting plate 5 is fixed on one side of the connecting angle steel 8, and the other end is connected with the push rod 2. The connections between the above-mentioned push rod connecting plate 5 and the connecting angle steel 8 and the push rod 2 are all rotatable. One side of the switch mounting bracket 7 is fixed on the connecting plate 9 , and the other s...

Abstract

The invention discloses a home elevator pit maintenance safety protection device. The home elevator pit maintenance safety protection device is characterized in that an ejector rod mounting support ismounted on one side of a guide rail, connecting angle steel is fixedly to one side of the ejector rod mounting support through a connecting plate, a switch mounting support is mounted on the connecting plate, a limit switch is arranged on the switch mounting support, the ejector rod connecting plate is installed on the inner side of the connecting angle steel, and one end of the ejector rod connecting plate is connected with an ejector rod used for abutting against a lift car through bolts. By the adoption of a hinge four-rod mechanism, the structure is simple, use is convenient, an elevatorcan quickly enter an anti-falling state, the situation that an electrical system, a spring and other complex structures need to be used in the past is avoided, the manufacturing cost is greatly reduced, and meanwhile the adverse situation that the elevator is connected and fixed to a pit through bolts in the past is avoided.

Description

technical field [0001] The invention relates to the technical field of home elevator equipment, in particular to a safety protection device for home elevator bottom pit maintenance. Background technique [0002] Now, home elevators are becoming more and more popular, and home elevators generally have relatively shallow pits, which leads to the need to lift the elevator to between the first floor and the second floor when the bottom of the car needs to be repaired. In the event of accidents such as movement or wire rope disconnection, the personnel who overhaul the car bottom will face personal danger. The purpose of the safety protection device for home elevator pit inspection is to ensure maintenance space when maintenance personnel enter the home elevator pit for maintenance, but most of the existing safety devices have the following disadvantages: [0003] (1) Its device uses complex structures such as electrical systems and springs, which greatly increases the cost and ...
