Abstract

The invention discloses an inside assembly lifting method of a bridge crane in a factory building under a closed environment; and the assembly lifting method comprises the steps of: construction preparation; assembly of a main beam; lifting of the main beam; lifting of a main trolley; and lifting completion. The assembly lifting is performed under the condition of not damaging an original factory building structure, so that the investment cost, the manufacturing cost and the safety cost caused by the disassembly work can be effectively reduced; the construction efficiency can be effectively improved; and the quality and the safety are guaranteed.

Description

Under enclosed environment, in factory building, crane in bridge type lifts method across interior assembling

Technical field

The invention belongs to technical field of building construction, specifically, to relate under a kind of enclosed environment crane in bridge type in factory building and lift method across interior assembling.

Background technology

Along with social development, industrial technology is constantly upgraded, and enterprise wants larger development, must be optimized upgrading, cause output to increase, need increase weight-lifting equipment existing production distribution.Increase weight-lifting equipment to need to carry out installation exercise in original factory building, and original mill construction can not carry out man-made further destroy; In original factory building, carry out crane in bridge type installation, giant caterpillar hoisting machine tool cannot put function and effect of its application to good use simultaneously; The many factors such as the increase of safety factor dangerous matter sources under smooth, the production model of installing cause safe, smooth, the stable difficulty that in factory building, crane in bridge type is installed under enclosed environment to strengthen to also have rhythm of production to ensure.

" crane constant lifting and hanging force pre-leveling lifts method " that China national Patent Office on June 16th, 2010 announces, it is mainly by the horizontal surface of weight center of gravity during hoisted in position, arrange three suspension centres with weight table body intersection place; First by suspension centre plane furnishing level when lifting starts, Synchronous lifting or revolution under crane vertical lifting afterwards, until lift in place by weight." beam hangs method and installs the method for crane in bridge type and the purposes of the method " of announcing in China national Patent Office on July 3rd, 2013 for another example, it mainly arranges suspension centre on factory building roof beam, and crane component part field ground is assembled and utilized winch and special hoisting gib head lifting crane in bridge type.At present, do not occur effectively ensureing that in factory building, crane in bridge type lifts method across interior assembling under the enclosed environment of progress, precision, safety and quality under enclosed environment in large bridge crane installation process yet.

Summary of the invention

The object of the invention is the deficiency existed for prior art, propose a kind ofly effectively to ensure that in factory building, crane in bridge type lifts method across interior assembling under the enclosed environment of progress, precision, safety and quality that crane in bridge type is installed.

Under a kind of enclosed environment, in factory building, crane in bridge type lifts method across interior assembling, and described assembling lifts and comprises the steps:

1) prepare before construction: carry out secondary repetition measurement to the crane beam track of original factory building, clear up lifting place, ground, recruitment facility are installed in inspection simultaneously;

2) assembling of girder: adjustment girder two ends height, makes it contour, measure camber and side sway degree, then the enclosure group on girder is installed to girder assigned position;

3) lifting of girder: girder comprises A girder and B girder, by mounted main cable and girder to end carriage place, but is not connected with end carriage;

4) lifting of main carriage: main carriage is placed on ground, below in the middle of A girder and B girder, A wheel crane and B wheel crane are placed in main carriage both sides respectively, armed lever extends respective angles respectively and highly catches on main carriage both sides simultaneously, lifting is to A girder and B girder top rail face height, pull immediately below A girder and B girder to main carriage by elevator, connect A girder and B girder, main carriage dropping place is on girder track;

5) lifting terminates: A wheel crane and B wheel crane armed lever are reclaimed, remove.

As preferred technical scheme, described step 2) in annex comprise cleading, equilibrium arm, platform, stair and, railing and electrical equipment.

As preferred technical scheme, when lifting in described step 3), trolley shifts to an earlier date segmentation dismounting in lifting region or draws electricity.

As preferred technical scheme, ensure that crane top is positioned at below factory building roof beam during described step 3) lifting, crane armed lever is not collided with girder.

Beneficial effect of the present invention: (1) is carried out assembling when not destroying original mill construction and lifted, effectively can reduce cost of investment, cost of manufacture and safety cost that dismounting work brings; (2) effectively can improve operating efficiency, ensure the quality of products and safety.

Accompanying drawing explanation

Fig. 1 is that under enclosed environment of the present invention, in factory building, crane in bridge type lifts the schematic diagram of method across interior assembling;

In figure: A girder 1, B girder 2, A wheel crane 3, B wheel crane 4, main carriage 5.
