Safety protection equipment for elevator maintenance

Abstract

The invention relates to the technical field of elevators, and discloses safety protection equipment for elevator maintenance. The safety protection equipment comprises a supporting mechanism, two protection mechanisms and an overhauling mechanism. The supporting mechanism comprises a base, the top surface of the base is fixedly connected with a soft cushion, and the top surface of the soft cushion is fixedly connected with a pedal. The two protection mechanisms are arranged on the two sides of the top surface of the soft cushion correspondingly. Each protection mechanism comprises a connecting base, the connecting base is fixedly connected to the top face of the soft cushion, and the soft cushion is filled with hydraulic oil. A connecting rod A is fixedly connected to the end, close to the outer side of the soft cushion, of the connecting base, a hole is formed in the end, away from the connecting base, of the front face of the connecting rod A, and a connecting rod B is sleeved with the hole. A clamping jaw is fixedly connected to the end, far away from the connecting rod A, of the connecting rod B. Due to arrangement of the protection mechanisms, When a maintenance worker steps on the upper portion of an elevator, the clamping jaws are automatically connected with steel cables, the steel cables are used for limiting the elevator and improving the stability of the elevator, so that the maintenance worker overhauling from the upper portion of the elevator is protected, the protection process is automatic, use is made convenient, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to safety protection equipment for elevator maintenance. Background technique [0002] During the use of the elevator, the elevator will be out of service due to problems such as elevator aging. In order to make the elevator operate again and eliminate the problem, maintenance workers need to go above the elevator to overhaul the elevator, and in order to ensure the safety of the maintenance workers during inspection, It is necessary to use protective safety devices to protect the maintenance workers during the maintenance process. [0003] The existing patent No. CN103130061B proposes an elevator maintenance device, which can reliably prevent the counterweight from falling abnormally, and can prevent a part of the operator's body from being caught by the counterweight, thereby improving safety. However, when the elevator fails and stops, The elevator is likely to be in a suspend...

[0003] The existing patent No. CN103130061B proposes an elevator maintenance device, which can reliably prevent the counterweight from falling abnormally, and can prevent a part of the operator's body from being caught by the counterweight, thereby improving safety. However, when the elevator fails and stops, The elevator is likely to be in a suspended state. For safety reasons, maintenance workers need to maintain the elevator from above the elevator. This device cannot protect the maintenance workers who inspect the suspended elevator from above.

[0004] The existing patent No. CN108046081B proposes an elevator broken rope protection device, which has the advantage that when the broken rope causes the car to fall, the mechanical action of the speed governor will also pull the safety gear to stop the car on the guide rail. The time is after the car has already fallen, and the inertia and impact force generated immediately after the car falls will easily throw the maintenance workers off. Even if the maintenance workers are protected by anti-fall devices such as slings, it is easy to cause collisions, extrusion and other hazards maintenance worker situation
