[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0015] like Figure 1 、 2 As shown in Figures 3 and 3, the overhead crane device for installing the corridor skylight roof of the utility model includes a bracket 1, a steel wheel 2, a steel pipe frame, a template, and a limiter.

[0016] like Figure 1 、 2 , 3 (the numbers marked in the drawings represent dimensional data, the unit is mm), the overall span of the overhead crane device is 9.5 meters and the width is 2.0 meters. The bracket 1 is assembled by welding several steel beams that meet the corresponding dimensional requirements. Among them, the two-way rods are welded one by one with a spacing of 50 cm, and the allowable deviation of the weld leg size is 0 to 4 mm; a steel wheel 2 is installed at the four corners of the bottom of the bracket 1 to facilitate the overall movement of the overhead crane device; limiters are installed on the steel wheels 2 to ensure that the steel wheels 2 are locked during construction, thereby ensuring the safety of construction.

[0017] A steel pipe frame is also set up on the bracket 1, and a template is laid on the upper part of the steel pipe frame as a construction platform for construction workers to walk and operate.

[0018] During actual use, after the limiter locks the steel wheel 2, the four corners of the overhead crane device are simultaneously tied to the steel columns on both sides with steel wire ropes to further ensure the safety of construction.

[0019] The steel beams constituting the bracket 1 are rectangular hollow steel sections, which include two specifications: cross-sectional dimensions of 50×50×3mm and cross-sectional dimensions of 100×50×3mm.

[0020] like Figure 1 、 2 As shown in FIG. 3 , the construction method of the overhead crane device for installing the corridor skylight roof according to the present invention includes the following steps:

[0021] Step 1: Layout and cutting of steel beams; cut the steel beams according to the dimensions on the drawing. The overhead crane has a span of 9.5 meters and a width of 2.0 meters. The specific dimensions can be adjusted according to the actual situation on site.

[0022] Step 2: Assemble the bracket 1 and steel wheel 2; weld the steel beams according to the designed dimensions to form the bracket 1, wherein the bidirectional rods are welded one by one with a spacing of 50 cm. There shall be no defects such as cracks, weld bumps, slag inclusions, etc. on the weld surface, and the allowable deviation of the weld leg size is 0 to 4 mm; a steel roller (i.e., steel wheel 2) is set at each of the four corners of the bottom of the bracket 1, and the steel wheel 2 shall not be rusted, damaged, bent, looped, kinked, cracked, or loose.

[0023] Step 3: Correction and hoisting; after the bracket 1 is assembled, the size is checked and accepted. When assembling the bracket 1, the overhead crane is first assembled on the floor. After the assembly is qualified, it is hoisted to the upper flip beam floor.

[0024] Step 4: Set up the steel pipe frame platform; set up the steel pipe frame at the bottom and lay the formwork at the top as the construction platform, and double fasteners are required to connect them.

[0025] Step 5: Install the limiters; install limiters on the four corners of the steel wheel 2. The steel wheel 2 is locked during construction. The four corners are tied to the steel columns on both sides with steel wire ropes to ensure the safety of construction.
