Hoisting construction method in confined space

Abstract

The present invention discloses a hoisting construction method in confined spaces. The method is based on a hoisting device for the confined spaces. The hoisting device comprises a flatcar and a hoisting mechanism. The construction steps comprise a first step of laying sliding rails and sliding the hoisting device for the confined spaces to a hoisting position; a second step of bundling up a to-be-hoisted object and connecting the to-be-hoisted object with the upper end of a derrick mast; a third step of starting a power device to drive the derrick mast to rotate around the lower end of the derrick mast in a vertical plane, so as to enable the upper end of the derrick mast to drive the to-be-hoisted object to move upwards until the to-be-hoisted object reaches a preset height; a fourth step of connecting a chain block with the to-be-hoisted object, pulling the chain block to adjust the height of the to-be-hoisted object, and discharging the to-be-hoisted object; and a fifth step of repeating the second to fourth steps till finishing hoisting work at the hoisting position. The hoisting construction method provided by the invention is used in confined conditions where large-scale hoisting machines cannot be used, the assembly and disassembly are convenient, the cost is low, the operation is simple and safe, limitation on construction sites is small, machine expenses are saved, the construction cost is reduced, and the method is safe and energy-saving.

Description

technical field [0001] The invention belongs to the technical field of construction equipment, and in particular relates to a hoisting construction method in a limited space. Background technique [0002] During construction, it is often necessary to hoist some equipment or materials to a height of several meters or more than ten meters. At present, cranes are usually used for hoisting, or tower cranes are installed on the construction site for hoisting operations. Although these two methods can complete the above-mentioned hoisting tasks, there are still some problems in the working process, such as the large size of the crane, which is greatly affected by the construction environment and site restrictions, resulting in the crane not being able to enter the construction site for operations. In addition, the cost of using the crane is relatively high, thereby increasing the construction cost. However, the installation period of the tower crane is longer, the cost is also hi...

Problems solved by technology

Although these two methods can complete the above-mentioned hoisting tasks, there are still some problems in the working process, such as the large size of the crane, which is greatly affected by the construction environment and site restrictions, resulting in the crane not being able to enter the construction site for operations. In addition, the cost of using the crane is relatively high, which increases the construction cost.

However, the installation period of the tower crane is longer, the cost is higher, and the dismantling work after use is also more troublesome, and it also prolongs the entire construction period.
