In order to overcome the above-mentioned problem that prior art exists, the utility model aims to provide a pulley block hoist and mount frame for coincide board class component solves the component that appears among the prior art through the assembly pulley and destroys easily, the hoist is difficult to balanced steady problem, has significantly reduced because the component damage problem that misoperation and hoist atress inequality reason caused.
An object of the utility model is to provide a assembly pulley hoist and mount frame for coincide board class component, include:
the lifting device comprises two lifting rings, two lower hanging rings and a pulley block, wherein the lifting rings are arranged on two symmetrical sides of the upper end of a lifting frame, the two lower hanging rings are arranged on two symmetrical sides of the lower end of the lifting frame, and the two lower hanging rings are connected with the pulley block through a lifting rope penetrating through the lower hanging rings.
Preferably, the pulley block comprises a plurality of fixed pulleys and a plurality of movable pulleys which are arranged in pairs, and the fixed pulleys are fixed on the lower end face of the hoisting frame.
Preferably, the lifting rope is a continuous steel rope.
Preferably, a lifting hook is arranged below the movable pulley.
Preferably, the number of the pulley blocks is 2, each pulley block is composed of 5 fixed pulleys and movable pulleys, and a lifting rope of each pulley block only bears half of the gravity of the laminated plate type component.
The utility model has the advantages that: the pulley block enables the component to be stably demoulded, lifted and lowered, the processes of unloading, hanging, moving, installing and the like of the laminated plate component are realized by adopting the construction method of matching the pulley block with the winch, the installation quality is met, the construction safety is ensured, the construction cost is reduced, and the referential experience is provided for similar projects.

Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings, which are not intended to limit the scope of the invention.
The first embodiment is as follows:
referring to fig. 1-6, a pulley block hoist for superimposed sheet like members comprises: the lifting device comprises two lifting rings 1, two lower hanging rings 2 and a pulley block, wherein the lifting rings 1 are arranged on two symmetrical sides of the upper end of a lifting frame, the two lower hanging rings 2 are arranged on two symmetrical sides of the lower end of the lifting frame, and the pulley block is connected through a lifting rope penetrating through the lower hanging rings 2. The pulley block comprises a plurality of fixed pulleys 3 and a plurality of movable pulleys 4 which are arranged in pairs, and the fixed pulleys 3 are fixed on the lower end face of the hoisting frame. The lifting rope is a continuous steel rope. A lifting hook is arranged below the movable pulley 4.
Example two:
in this embodiment, a pulley block hoist and mount frame for coincide board class component includes: the lifting device comprises two lifting rings 1, two lower hanging rings 2 and a pulley block, wherein the lifting rings 1 are arranged on two symmetrical sides of the upper end of a lifting frame, the two lower hanging rings 2 are arranged on two symmetrical sides of the lower end of the lifting frame, and the pulley block is connected through a lifting rope penetrating through the lower hanging rings 2. The arrangement of the pulley block is different from the first embodiment, the arrangement of the pulley block is composed of 2 50t sub-pulley blocks, each sub-pulley block is composed of 5 fixed pulleys 3 and a movable pulley 4, and a lifting rope of each sub-pulley block only bears half of the gravity of the laminated plate type component.
After the superposed plate type components are in place, the pulley block is matched with the manual hoist to perform alignment, the horizontal coordinate position of the superposed plate type components is measured by a line hammer method, and the superposed plate type components are aligned by hanging line hammers downwards from the longitudinal and transverse center lines of the superposed plates on the top plate beam. When the position of the composite plate type component is adjusted and moved, the composite plate type component is lifted for adjustment, when the alignment is not finished, the binding rope of the composite plate is not loosened, and the horizontal communicating pipe is adopted to measure the elevation and the level of the composite plate according to the elevation point marked on the steel frame upright post. The engineering requirements of this example: the central line elevation of the laminated slab is +/-5 mm, the longitudinal and transverse non-levelness is 2mm, and the central displacement is +/-5 mm.
And then, hoisting the pulley block hoisting frame by using the truss crane, slowly moving the hoisting frame to the position above the laminated slab, hooking according to requirements, slowly hoisting, and enabling the component to be lifted and lowered in a stable demoulding manner by using the pulley block.
The construction method of the pulley block matched with the winch is adopted, so that the processes of unloading, hanging, moving, mounting and the like of the laminated plate type member are realized, the mounting quality is met, the construction safety is ensured, the construction cost is reduced, and the referential experience is provided for similar projects.
