Although the height transportation of building material has been solved to above-mentioned patent, when roofing construction, can not realize the building material of roofing different positions and carry, the workman's of being inconvenient for construction has certain use limitation.

Disclosure of Invention

The simple crane for the construction of the building roof is simple in structure and convenient to operate, realizes the conveying of building materials at different positions of the roof while the height transportation of the building materials is realized, facilitates the construction of workers, is high in automation degree, and saves manpower while improving the construction efficiency.

In order to solve the technical problem, the utility model discloses the technical scheme who takes is, building roofing construction is with simple and easy lifting machine, the on-line screen storage device comprises a base, base one side correspondence is equipped with fixed chamber, is equipped with an outer ring respectively and fixed chamber welded bearing in two fixed intracavity, and the welding has the fixed column on the bearing inner ring, two fixed capital portion one sides are equipped with the guide bar respectively, are equipped with the hoist engine respectively in two fixed column one sides to and locate the wire rope that is used for lifting by crane building material on the hoist engine, be equipped with the couple in wire rope one end, be equipped with first pulley on the stand top surface, be equipped with the second pulley in the stand side, be equipped with the third pulley in guide bar one end, be equipped with one on the fixed column when building material lifts by crane to the roofing after, be used for the manipulation handle of rotatory fixed column, be equipped with.

The simple crane for building roof construction further comprises a first position sensor for detecting the resetting of the operating handle, a second position sensor for detecting the lifting position of the hook, a tension sensor for detecting the tension of the steel wire rope, and a controller for receiving signals of the two position sensors and the tension sensor to control the opening and closing of the winch.

The utility model discloses building roofing construction is with simple and easy loop wheel machine's beneficial effect is, its simple structure, convenient operation, when solving building material's height transportation, realized the building material of the different positions of roofing and carried, make things convenient for workman's construction, through setting up two fixed columns and hoist engine, alternate work has greatly improved conveying efficiency, and the fixed column both sides workman of being convenient for is under construction simultaneously, has improved the efficiency of construction, and degree of automation is high, has practiced thrift the manpower.
