Safety protection equipment for elevator maintenance

Abstract

The invention relates to the technical field of elevators, and discloses a safety protection device for elevator maintenance, which includes a support mechanism, a protection mechanism and an overhaul mechanism. Pedal, the number of protective mechanisms is two and they are respectively arranged on both sides of the top surface of the cushion. The protective mechanism includes a connecting seat, which is fixedly connected to the top surface of the cushion. The interior of the cushion is filled with hydraulic oil, and the connection seat is close to the outside of the cushion. One end of the connecting rod A is fixedly connected with the connecting rod A, and the end of the connecting rod A away from the connecting seat is provided with a hole, and the connecting rod B is inserted in the hole, and the end of the connecting rod B far away from the connecting rod A is fixedly connected with a claw, through the protection mechanism Setting, when the maintenance worker steps on the elevator, the claw is automatically connected with the steel cable, and the steel cable is used to limit the elevator and increase the stability of the elevator, so as to protect the maintenance workers from the elevator. The protection process is automated, easy to use and highly efficient.

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
