Problems solved by technology

However, in practical applications, there is still a certain failure rate in the safety gear structure. Elevator accidents are mostly caused by the failure of the safety gear. Therefore, the traditional elevator structure urgently needs a safety protection structure to ensure that after the elevator reaches the floor and stops, the user enters and exits the elevator. , the elevator will not fall or rush to the top
In addition, when the user takes the elevator, he cannot intuitively judge whether there is a hidden danger in the elevator, that is, he cannot intuitively judge whether the elevator reaching the floor has a safety hazard of falling or rushing to the top, and it is also impossible to judge whether the safety gear is working normally.
Since the safety hazards of traditional elevators cannot be visualized and passengers cannot judge, once an emergency occurs, the consequences will be devastating

Embodiment 1

[0028] This embodiment discloses a bolt-type safety protection structure for elevators, see figure 1 , the safety guarantee structure is provided with four fixing pins 100, which are arranged symmetrically in pairs on the top and bottom of the elevator car 20 respectively. Four fixed pins 100 are placed inside the elevator shaft 10, and are fixedly arranged on the body of wall 30. Each fixed pin 100 is connected with a power mechanism (not shown in the figure), and the power mechanism drives the fixed pin 100 to move horizontally ( figure 1 The middle arrow indicates the moving direction of the fixing pin 100). During work, the power mechanism drives the fixed pins 100 to stretch out after the elevator car 20 reaches the floor and stops (before the elevator door is opened), and the four fixed pins 100 jointly limit the upward or downward movement of the elevator car 20; (after the elevator door is closed), when needs continue to rise or fall, the power mechanism drives four f...

Embodiment 2

[0035] The function of this embodiment is basically the same as that of Embodiment 1. The difference is that in this embodiment, four grooves corresponding to the fixing pins 100 are provided on the top and bottom of the elevator car 20. After the four fixing pins 100 are stretched out, respectively Insert into the four grooves to realize the limit of the elevator car 20.

Embodiment 3

[0037] The function of this embodiment is basically the same as that of Embodiment 2. The difference is that the fixing pins 100 of this embodiment are respectively arranged on the top and the bottom of the elevator car 20, and the grooves are arranged on the wall 30, which are connected with the fixing pins 100. One to one correspondence.

[0038] In practical applications, eight fixing pins 100 can be provided, which are respectively placed at the four corners of the top and bottom of the elevator car 20 .

Abstract

The invention discloses a bolt type safety guaranteeing structure for an elevator. The bolt type safety guaranteeing structure comprises at least two fixing mechanisms which are transversely arranged in an elevator shaft. The fixing mechanisms are connected with a power mechanism. After an elevator car reaches the floor and stops, the power mechanism drives the fixing mechanisms to transversely extend out to limit the elevator car, and the elevator car is limited from moving upwards or downwards. Fixing pins capable of performing telescopic movement are arranged, and after the elevator reaches the floor, the fixing pins extend out to limit upward or downward movement of the elevator, that the situation that after reaching the floor, the elevator suddenly falls down or rushes upwards is effectively prevented, and the safety of the elevator is greatly improved.

Description

technical field [0001] The invention relates to the field of elevator structures, in particular to a bolt-type safety guarantee structure for elevators. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. In recent years, elevator accidents have occurred frequently, especially in the process of passengers entering and exiting after the elevator reaches the floor and stops opening the door. The traditional elevator structure uses the safety gear structure to realize elevator braking in emergencies. When an emergency occurs, the safety gear clamps the guide rail, and at the same time firmly clamps the car on the guide rail to realize the safety of the car. move. However, in practical applications, there is still a certain failure rate in the safety gear structure. Elevator accidents are mostly caused by the failure of the safe...
