A universal spreader for hoisting steel pipes and steel plates

Abstract

The invention discloses a universal lifting sling for lifting steel pipes and steel plates. The universal lifting sling consists of a base plate, mounting plates, sheet pressing devices and pipe pressing devices. The mounting plates are disposed above the base plate, the lower two ends of the mounting plates are in fixed connection with the base plate through support plates, one sides of the mounting plates are fixedly equipped with the sheet pressing devices, several groups of fixed columns are fixedly arranged between the sheet pressing devices and the mounting plates, whetstone platforms fixed under the mounting plates are disposed right below the sheet pressing devices, the other sides of the mounting plates are fixedly equipped with the pipe pressing devices, and the pipe pressing devices are arranged above the base plate. The universal lifting sling provided by the invention has the characteristics of simple structure and convenient use, can achieve slinging of steel plates and steel pipes simultaneously, has no need for better sling, saves time, can complete slinging and transportation of steel plates and steel pipes, is convenient in operation, has strong practicality, andis convenient for popularization and use.

Description

technical field [0001] The invention belongs to the technical field of steel material hangers, in particular to a general-purpose hanger used for hoisting steel pipes and steel plates. Background technique [0002] Steel structure building is one of the main building types at present. Because steel has high strength, light weight, good overall rigidity and strong deformation ability, it is especially suitable for building long-span, super high and super heavy buildings; material homogeneity With good isotropy and isotropy, it is an ideal elastic body, which is most in line with the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformation, and can withstand dynamic loads well; the construction period is short; its high degree of industrialization can be Carry out specialized production with a high degree of mechanization. [0003] Steel structures such as steel plates and steel pipes have a wide range of a...

Problems solved by technology

[0003] Steel structures such as steel plates and steel pipes have a wide range of applications. When the steel structure products are smelted and formed in the factory, they need to be transported to a specific location, or they need to be transported to a high place on the construction site, and they need to be hoisted to facilitate transportation. To the designated position, in the process of hoisting the steel, the firmness of the clamping is the first problem to be solved. If the steel slides from a high place, it will cause damage to the material, and in more serious cases, it will cause personnel damage. Casualties, so the steel needs to be firmly fixed during transportation. For steel plate building materials, because of its large contact area, it is not easy to slide, so it is more convenient to fix. For tubular building materials such as steel pipes, because it is easier to roll, it is easier to fix It is inconvenient, so a specific fixing device is required. Therefore, when handling steel plates and steel pipes, two sets of different hoisting tools are required for hoisting. During hoisting, it is necessary to replace between the two, which consumes a lot of time and cannot be completed quickly. hoisting task, so a new technical means is needed to solve this technical problem
