Description

TECHNICAL FIELD

[0001] The utility model relates to a lifting appliance technical field, concretely is a hoist. BACKGROUND

[0002] In modern thermal power plant construction, especially in gas engineering projects, the internal space design of the main plant is increasingly compact in order to optimize the use of limited building volume and meet the needs of efficient operation. This compact design brings significant challenges to equipment installation and hoisting operations, especially during the hoisting of large or heavy equipment.

[0003] Traditional hoisting methods usually rely on a beam structure, which has two main application methods in actual operation: one is to use a main hook at the bottom of the beam for hoisting; the other is to pass a steel cable through the upper part of the beam to achieve hoisting. However, both methods have obvious limitations in the current space-limited environment. For the former, adding a main hook further compresses the already limited vertical working space, increases the difficulty of construction, and may affect the arrangement and installation of other equipment; for the latter, although it does not occupy additional vertical space, the lack of effective fixing devices causes the steel cable to shift or move when under load, which not only threatens the safety and stability of hoisting, but also increases construction risks and potential economic losses, therefore a hoist is proposed.

[0007] As a further scheme of the utility model: the end faces of the two steel plates not adjacent to each other are provided with a plurality of reinforcing ribs connected with the beam.

[0008] As a further scheme of the utility model: the fixing piece comprises a fixing sleeve sleeved on the outer surface of the pin shaft, the outer surface of the pin shaft is further provided with a clamping sleeve, and the clamping sleeve is connected with the fixing sleeve by bolts.

[0009] As a further scheme of the present utility model: two said external hanging assemblies are symmetrically arranged on the outer surface of the beam.
