Description

Technical Field

[0001] The invention belongs to the technical field of mining hanging platforms, and in particular relates to a multi-layer double-beam cantilevered shoulder pole type hanging platform for installing shaft equipment. Background Art

[0002] In China, large-scale wellbore equipment installation and construction mostly adopts round hoisting plates. This type of hoisting plate has many problems such as large size, heavy weight, and difficulty in opening the large hinges during use. It cannot adapt well to the complex construction environment of symmetrical arrangement of double lifting facilities in large wellbore (diameter above 8m). Due to the large number of components in the wellbore and limited construction space, the construction hoisting plate has to adopt the mode of main plate plus movable hinges to ensure the construction space. At the same time, in order to ensure that the lifting plate is not affected, the main plate is generally small and the movable hinges are large. The large movable hinges also bring higher safety risks. After the installation of the wellbore equipment steel components is completed, the wellbore is divided into multiple areas. If the hoisting plate is used for maintenance or cable laying, the large hinges on both sides of the hoisting plate must be removed. The construction personnel must go up to the steel components to carry out construction, which increases the safety risk. There is also a kind of construction hoisting plate that uses multiple ropes to hang the main hoisting plate and the sub-hoisting plate respectively. It uses more well drilling winches and lifting wire ropes, consumes more electricity, and has poor economic benefits. Summary of the invention

[0021] As a preferred embodiment of the present invention, the folding leaf comprises a main hanging tray folding leaf 8 installed on the main hanging tray 1 and a secondary hanging tray folding leaf 9 installed on the secondary hanging tray.
