Description

Elevator hauler row car device

Technical Field

The utility model relates to a manufacturing technical field especially relates to an elevator hauler row car device.

Background

At present, the safety of the elevator is not paid attention by people, if the elevator cannot run in case of power failure or fault, the elevator car stops between two layers, passengers cannot leave the elevator car, and therefore the elevator car is manually operated by elevator maintenance personnel to reach a flat-bed position and release trapped passengers. The following method is adopted: firstly, after a maintenance worker arrives at a stranded site, a fence is placed at a first floor door or a warning board which is used for maintenance and is stopped is placed at a striking position of the floor door. Two persons operate the elevator in the machine room, and the intercom system is used for contacting passengers trapped in the car, so that passengers in the car are pacified and prevented from scaring, and passengers trying to take a door out of the car are prevented. And secondly, pressing a sudden stop switch on the control cabinet, closing a power supply main switch, then detaching a disc wheel switch, and assembling disc wheels. And thirdly, one person releases the internal contracting brake by using a manual brake releasing device, and the other person rotates the wheel of the disc to enable the car to reach a target landing and release trapped passengers.

At present, regulations require that no less than two persons are needed for elevator maintenance and emergency rescue, so that most of the rescue is a group of 2 persons under common conditions. There are many situations of people trapping, and other situations are not described in detail, and only one situation is described here. The lift lightly carries and dashes the top, and the car stops in the non-door zone, just needs manual barring downwards this time, because the quality to the heavy side is greater than the car side, so need very big torsion, manual release band-type brake alone, alone the barring probably coiled motionless, this often appears in the practice process, and the torsion that the elevator that carries the quality bigger needs the barring is big more. Moreover, the strength of people is not constant, if the two people are not well matched, the wheel of the barring cannot be grabbed when the force of maintenance personnel of the barring is weak, and the person who loosens the band-type brake cannot timely release the brake, the car can slide upwards, so that secondary accidents or even injuries can be caused. In actual operation, the capacity of two people for turning over the vehicle is insufficient and still outstanding. The safety can not be completely ensured, and if one person guides the trapped passengers to have more stable correct rescue behaviors in the car in the near flat zone of the car in the turning process, more maintenance personnel are needed. The disk wheel is inserted into a small hole specially reserved for the disk wheel on the traction machine, and the disk wheel is provided with a gear which can be meshed with the gear on the traction wheel. However, since the anti-drop device is not provided, the gear engagement between the traction sheave and the turning wheel is not guaranteed, and the traction sheave may be separated during turning, which is quite dangerous.
