Summary of the invention

First technical problem that the present invention will solve just is to provide the lightweight roof panels installed rows mule carriage that a kind of operating efficiency is high, labour intensity is little, safety factor is high.

For solving the problem, the technical scheme that lightweight roof panels installed rows mule carriage of the present invention adopts is: comprise the support body with two row's supporting legs, travel wheel is provided with below described supporting leg, described support body is provided with the elevating mechanism with lifting hook, and the height of described wherein row's supporting leg is less than the height of another row's supporting leg.

Its additional technical feature is:

Described number of often arranging supporting leg is two, and described supporting leg is positioned at described support body surrounding.

Second technical problem that the present invention will solve just is to provide a kind of method using the mule carriage of above-mentioned lightweight roof panels installed rows to carry out the installation of lightweight roof panels.

For solving the problem, the technical solution used in the present invention is:

The method comprises the following steps:

The first step, installs the roof panels near building one end

With crane by near building one end one across roof panels installation in position;

Second step, installs adjacent first piece of roof panels across end

With crane by with mounted one across adjacent one across first piece of roof panels installation in position of end;

3rd step, installs side slideway

Upper side slideway is fixed on installation in position one across roof panels above;

4th step, installs lower side slideway

The lower side slideway parallel with upper side slideway is fixed on roof panels bracing frame on the upper surface in outside;

5th step, is lifted on the mule carriage of lightweight roof panels installed rows on upper side slideway and lower side slideway

The mule carriage of lightweight roof panels installed rows sling with crane or other lifting device, make the travel wheel of short supporting leg be placed in side slideway, the travel wheel of the side making supporting leg high is placed in lower side slideway;

6th step; Roof panels to be installed is placed in above first piece of roof panels

By need the roof panels of installing be lifted on this across first piece of installation in position roof panels above;

7th step, hangs away installation by roof panels lightweight roof panels installed rows to be installed mule carriage, again lifts next block roof panels to be installed simultaneously

The mule carriage of lightweight roof panels installed rows is moved to above first piece of roof panels, start elevating mechanism, lifting hook is reduced, hang on the hoisting rope of roof panels, then lifting hook and roof panels to be installed are together risen, the mule carriage of lightweight roof panels installed rows is moved forward, behind in-position along on upper side slideway and lower side slideway, lifting hook and roof panels to be installed are reduced, makes roof panels be placed on bracing frame; Simultaneously with crane by roof panels to be installed for next block lifting to should across above first piece of roof panels, and so forth, until should across the whole installation in position of roof panels;

8th step, repeats second step to the 7th step, until all install.

The method that lightweight roof panels installed rows mule carriage provided by the present invention and roof panels are installed compared with prior art, have the following advantages: one, owing to comprising the support body with two row's supporting legs, travel wheel is provided with below described supporting leg, described support body is provided with the elevating mechanism with lifting hook, the height of described wherein row's supporting leg is less than the height of another row's supporting leg, when installing roof panels, first with crane by near building one end one across roof panels installation in position, then with crane by with one of installation in position across adjacent one across first piece of roof panels installation in position of end, upper side slideway is fixed on installation in position one across roof panels above, the lower side slideway parallel with upper side slideway is fixed on roof panels bracing frame on the upper surface in outside, the mule carriage of lightweight roof panels installed rows sling with crane or other lifting device, make the travel wheel of short supporting leg be placed in side slideway, the travel wheel of the side making supporting leg high is placed in lower side slideway, by need the roof panels of installing be lifted on this across first piece of installation in position roof panels above, installation is hung away in roof panels lightweight roof panels installed rows to be installed mule carriage, again lifts next block roof panels to be installed simultaneously, repeat above-mentioned steps, until all install, upper side slideway is positioned at above mounted roof panels, lower side slideway is fixed on roof panels bracing frame on the upper surface in outside, lightweight roof panels is made to be limited in inside slideway, lightweight roof panels installed rows walks the width of vehicle-width slightly larger than roof panels, roof panels keeps flat in the mule carriage of lightweight roof panels installed rows, and lifting freely, be convenient to the installation of roof panels, staff stands in above the roof panels that has been in place, promote or pull the mule carriage of lightweight roof panels installed rows to assigned address, safety factor is high, labour intensity is little, operating efficiency is high, its two, because described number of often arranging supporting leg is two, described supporting leg is positioned at described support body surrounding, walking more freely.
