Technical Field

The invention relates to the technical field of elevator disassembly and assembly, in particular to a machine-room-less elevator disassembling method.

Background

The elevator is a common device in the prior art and is widely applied to buildings with higher floors. It can be divided into an elevator with a machine room and an elevator without a machine room according to the installation space of the elevator. The machine room of a machine room elevator is usually arranged at the top floor of a house, and the main devices in the machine room are a traction machine and a control cabinet. The biggest difference between the elevator without the machine room and the elevator with the machine room is that the equipment in the machine room is miniaturized as much as possible on the premise of keeping the original performance by utilizing the modern production technology, so that the machine room with the elevator with the machine room is cancelled, and the equipment is small enough to be installed into the main equipment by utilizing the space on the top of the elevator shaft or the side of the elevator shaft as little as possible.

At present, the dismantling process of the elevator with the machine room has mature technology and related processes in the industry, but the related dismantling process of the elevator without the machine room has less records.

Disclosure of Invention

The invention aims to provide a machine-room-less elevator dismantling method which has the characteristic of quickly dismantling facilities in a hoistway.

The above object of the present invention is achieved by the following technical solutions:

a machine-room-less elevator dismantling method comprises the following steps:

s1: entering an initial disassembly position, and driving the counterweight to leave the bottom of the counterweight guide rail;

s2: the installation of the towing installation, comprising the following procedures,

arranging a support at the bottom of the counterweight guide rail;

installing a hoisting device;

s3: the dismantling operation, including the following processes,

the lift car is driven to move upwards through the hoisting device, the counterweight moves downwards to be compacted, the hoisting rope is loosened, and the hoisting rope is mechanically broken and disassembled;

dismantling the traction machine;

sequentially removing the parts in the shaft from top to bottom;

and dismantling the car and the counterweight.

By adopting the technical scheme, the lift car is driven to move by utilizing the hoisting device which is arranged later, so that after the hoisting rope is loosened, the operations of separating the lift car from the counterweight, breaking and detaching the cable, detaching the speed limiter and the steel wire rope thereof and the like can be carried out subsequently, a complex scaffold does not need to be built, the construction period is shortened, the cost is lower, and the related process of detaching the elevator without a machine room in the industry is supplemented.

The invention is further configured to: before the dismantling operation of S3, the method also comprises a step of arranging protective measures, which comprises the installation of a safety rope and is mainly taken from the following processes:

a safety rope is fixed at the steel structure of the top hall door;

the safety rope is fixedly connected with a car girder.

Through adopting above-mentioned technical scheme, insurance rope one end is fixed on the steel construction, and the other end is fixed on the car girder, prevents that hoisting apparatus is malfunctioning to cause the car to fall.

The invention is further configured to: the step of arranging the protective measures also comprises secondary safety measures which are mainly taken from the following processes that a pair of limiting ropes is respectively arranged on the left side and the right side of the car girder, the limiting ropes penetrate through a gap between the car guide rail and the shaft wall, and two ends of the limiting ropes are fixed on the car girder.

By adopting the technical scheme, the rope head of the limiting rope bypasses the car girder, the rope head is fixed by the U-shaped clamp after being pressed, the limiting rope can be clamped on the intersection point of the car track and the track support when the car falls, the car is prevented from continuously falling, and the personal safety of constructors is ensured.

The invention is further configured to: the installation hoisting apparatus includes:

hanging a steel wire rope rigging on a lifting hook close to the middle of the top of the hoistway;

an electric hoist is hung on the steel wire rope rigging;

and hanging a girder of the lift car on a lifting hook of the electric hoist.

Through adopting above-mentioned technical scheme, electric block has characteristics such as small, the dead weight is light, easy operation, convenient to use, utilizes electric block drive car, can make things convenient for the staff on sedan-chair top to dismantle the operator, can stop at any time moreover and prevent that the car from removing, very safety.

The invention is further configured to: the removed components are delivered from the nearest hall door.

By adopting the technical scheme, the components are delivered from the nearest hall door and then are subsequently carried, so that the disassembly work is convenient, and the later-stage arrangement is also convenient.

The invention is further configured to: when the lift car is dismantled, the lift car top steel wire rope is cut off, and the lift car top guardrail, the lift car top cross beam, the lift car top, the lift car wall and the lift car bottom are dismantled one by one according to the sequence.

Through adopting above-mentioned technical scheme, demolish the car in order, dismantle the back that finishes, the staff in the well is whole to leave the well.

In conclusion, the invention has the following beneficial effects:

1. when the elevator is dismantled, the hoisting rope is loosened to facilitate the operations of separating the car from the counterweight, breaking and dismantling the cable, dismantling the speed limiter and the steel wire rope thereof and the like in the following process, and a complex scaffold is not required to be built, so that the construction period is shortened, and the cost is lower;

2. through arranging twice safety measure protection and taking place, can prevent effectively that hoisting apparatus is malfunctioning to cause the emergence of the car condition of falling, guarantee constructor's personal safety.
