Abstract

The invention discloses a self-adaptive fixed prefabricated building steel hoisting device which comprises a hoisting device main body, a hoisting steel wire rope, a mounting block, a lifting hook, and a connecting rope; the left side of the hoisting device main body is connected with the hoisting steel wire rope; the mounting block is fixed to the lower end of the hoisting steel wire rope; the lifting hook is arranged below the mounting block; the connecting rope is fixed to the upper end of the lifting hook; a movable plate is fixed to the upper end of the connecting rope; the movable plateis arranged in the mounting block; and a first reset spring is arranged at the outer side of the movable plate. The self-adaptive fixed prefabricated building steel hoisting device is provided with astandby steel wire rope, a winding roller and a limiting rod, the mounting block can be connected through the standby steel wire rope, when the hoisting steel wire rope is abnormal, the standby steelwire rope can still provide stable tension for the mounting block, and the winding roller can be kept fixed under the cooperation of the limiting rod and a limiting groove, so that the standby steel wire rope can be kept stable at a later stage, and the use safety of the device is improved.

Description

technical field

[0001] The invention relates to the technical field of lifting devices, in particular to an self-adaptive and fixed assembled building steel lifting device. Background technique

[0002] With the improvement of construction technology, the application of prefabricated buildings is becoming more and more extensive. Compared with traditional buildings, prefabricated buildings have faster construction efficiency and less maintenance time for buildings. Steel is indispensable in prefabricated buildings. One of the raw materials, when transferring steel, due to its high quality, it is generally transferred by lifting devices, but there are still some shortcomings in the use of existing lifting devices:

[0003] 1. The existing lifting device generally winds the wire rope through the hoist to lift the steel. The device only relies on the self-locking of the hoist to limit the position of the wire rope to keep the steel stable during hoisting. However, when the self...
