Description
Technical Field
The utility model belongs to elevator derrick field especially relates to a dismantlement formula elevator derrick under Luban technology.
Background
The elevator derrick is of a steel structure and is generally manufactured at an elevator construction site, that is, in an elevator hoistway. The existing elevator shaft frame is manufactured by conveying a steel section to a construction site before manufacturing, then cutting the steel section according to the height of an elevator shaft, welding the cut steel section into a shaft frame, painting the shaft frame, drying the paint, and finally installing an electrical element.
Because the derrick is formed by welding the steel sections one by one, the derrick is very high in height and heavy in weight, the steel sections are difficult to place and position on the derrick, much time is consumed, and the welding time of the derrick is long; since many welding works are performed at high altitude, the welding environment of workers is severe, and even many safety measures are taken to perform welding, which also results in long welding time. Derusting is needed before painting of the derrick, the derrick is large in size and high in height, derusting is difficult, and time consumption of a painting step is long; the paint is divided into several passes in order to form a thicker paint film, each pass of paint being dried before the next pass of paint can be carried out, which also makes the painting step time-consuming. The electrical components on the elevator derrick are numerous, most of the electrical components are located at the higher position of the elevator derrick, the installation is difficult, and the installation of the electrical components in the prior art generally takes four days and takes a long time. The statistics show that the manufacturing period of the existing elevator derrick is as long as 40 days. The elevator derrick is too long in manufacturing period, so that project progress is delayed, default phenomena and the like are caused, and loss is caused to enterprises.
When the derrick is welded, a large amount of irritant toxic gas is generated, and the environment is polluted. After the derrick is welded, an iron hammer is required to knock a welding point to release welding stress, the sound of knocking by the iron hammer is very loud, and environmental pollution, mainly pollution on noise, exists. When the well frame is painted, the paint can release irritant gas and can pollute the environment.
When the upper part of the derrick is welded, the welding seam is positioned in the air, the wind speed is high, and the welding coating is easily blown away by wind, so that the welding strength is insufficient. In addition, welding is a highly professional technique, the skill requirement of workers is high, it is very difficult to recruit a good welder, and in a practical situation, workers who are only simply trained are often used for welding the derrick, and the welding skill is general. The above results in lower overall structural strength of the elevator mast.
In addition, the length of the steel section for welding the derrick is very long, generally about 12 meters, and a cart is required for transportation; the electric elements arranged on the derrick are numerous, and need to be packed separately in a wooden box in the transportation process, so that the accumulated volume is large; in addition, a large number of devices are used throughout the manufacturing process of the elevator mast, including cutting machines, welding machines, a series of debugging instruments for the installation of electrical components, etc., which also need to be transported to the construction site. Therefore, before the construction of the existing elevator derrick, a large number of large vehicles are needed to transport related parts and equipment, the transportation cost is high, for example, the parts and equipment of the elevator derrick with the 1T specification are transported, two 13-meter trucks are needed to transport the parts and equipment, for example, the transportation distance is 1000 kilometers, and the transportation cost is up to 20000 yuan.
Therefore, the existing elevator derrick has the defects of long manufacturing period, environmental pollution caused during manufacturing, lower overall structural strength and high transportation cost.
