DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 、 Figure 2 、 Figure 3 The utility model provides a steel structure component transportation device, including a rectangular base plate 1, the rectangular base plate 1 is a load-bearing foundation welded by square steel and skin, universal wheels 3 are installed at the four corners of the lower surface of the rectangular base plate 1, and columns 4 are fixedly installed at the four corners of the upper surface of the rectangular base plate 1. The four side walls of the rectangular base plate 1 are hinged with shielding plates 7 by hinges. The shielding plates 7 are a shielding foundation welded by square steel and metal mesh, and the two ends of the shielding plates 7 are connected to the adjacent columns 4 by handle buckles 6; the handle buckles 6 are existing components composed of buckles and hooks, the buckles are fixedly installed on the shielding plates 7, and the hooks are fixedly installed on the columns 4, and the shielding plates 7 can be connected and separated from the columns 4 by the handle buckles 6. When connected, the four sides can be shielded, the volume can be increased, and the steel structure stored inside can be prevented from slipping. In addition, one or more shielding plates 7 can be swung downward to open, and the steel structure stored inside can be conveniently unloaded.

[0023] The rectangular base plate 1 is provided with a receiving groove, in which a folding ladder 13 is rotatably installed by a pin 12. The folding ladder 13 is an existing component that can be folded into a V shape and unfolded into a straight line. A crossbeam 2 is evenly fixedly installed on the inner bottom of the receiving groove. The crossbeam 2 is used to support the folding ladder 13 unfolded into a straight line to ensure the load-bearing capacity; the folding ladder 13 is provided with a clamping assembly 8 at one end away from the pin 12, and guide grooves 9 are provided on both sides of the interior of the receiving groove. Positioning holes 10 are provided at both ends of the guide groove 9, and the clamping assembly 8 is plugged into and assembled with a pair of aligned positioning holes 10; the clamping assembly 8 can be manipulated to be plugged into the positioning holes 10 at different positions along the guide groove 9, thereby fixing the shape of the folding ladder 13.

[0024] Specifically, the clamping assembly 8 includes a latch 81 and an operating rod 83. A pair of pins 84 are fixedly installed in the middle of the end of the folding ladder 13. The same operating rod 83 is slidably installed on the pair of pins 84. The operating rod 83 is provided with a through hole for passing the pin 84. One end of the connecting rod 82 is rotatably installed at both ends of the operating rod 83, and the other end of the connecting rod 82 is rotatably installed with the latch 81. Guide holes are provided on both sides of the end of the folding ladder 13. The latch 81 passes through the guide holes respectively and is slidably assembled with the guide groove 9; when the operating rod 83 is laterally translated on the pin 84, the latch 81 can be pushed and pulled through the connecting rod 82 to connect or separate the latch 81 with the positioning hole 10. When the latch 81 is in a separated state from the positioning hole 10, the latch 81 will not separate from the guide groove 9.

[0025] Furthermore, the pin 84 is provided with a cylindrical spring 85, which is pressed between the folding ladder 13 and the control rod 83; the cylindrical spring 85 enables the control rod 83 to have a force to move closer to the nail cap side of the pin 84, thereby ensuring the reliability of the connection between the pin 81 and the positioning hole 10.

[0026] When the operating rod 83 abuts against the nail head of the pin 84, the center lines of the operating rod 83, the connecting rod 82 and the latch 81 coincide, and the latch 81 is plugged into the positioning hole 10; and when the operating rod 83 is forced to move closer to the folding ladder 13 and compress the cylindrical spring 85, the connecting rod 82 pulls the two latches 81 closer to each other, temporarily separating the latches 81 from the positioning hole 10.

[0027] The distance between the pin 12 and the right end of the folding ladder 13 is at least 20 cm, so that when the folding ladder 13 is folded into a V shape for use, the right end of the folding ladder 13 is against the ground; in conjunction with the locked universal wheel 3, the friction force of positioning and placement can be increased, thereby improving the placement stability.

[0028] Another structure that can be added is as follows: the pin 12 is provided with a torsion spring 11, and the two ends of the torsion spring 11 are fixedly assembled with the accommodating groove and the folding ladder 13 respectively; this makes the right half of the folding ladder 13 have a clockwise swinging force, which facilitates the formation of a V shape and saves effort in operation.

[0029] Lifting rings 14 are evenly and fixedly installed on the four side walls of the rectangular base plate 1 to facilitate the crane to lift and transfer the entire plate.

[0030] A handrail frame 5 is fixedly installed between at least a pair of adjacent columns 4. One to four handrail frames 5 can be provided. The handrail frames 5 are used to improve the overall convenience of pushing and transferring.

[0031] The working principle of this embodiment is as follows:

[0032] After opening at least one shielding plate 7 through the handle buckle 6, the steel structure components are loaded onto the rectangular base plate 1. After completion, the shielding plates 7 are locked to form a surrounding barrier. The entire structure can be easily moved horizontally through the handrail frame 5 and the universal wheel 3. When loading is required, the crane can lift the entire structure through the lifting ring 14. When arriving at the site, open at least one shielding plate 7 again, unload the steel structure components, and then assemble the steel structure components.

[0033] When it is necessary to climb up, the handheld control lever 83 is pressed toward the side close to the folding ladder 13, and the cylindrical spring 85 is compressed at the same time. The connecting rod 82 pulls the two latches 81 closer to each other, so that the latch 81 is temporarily separated from the positioning hole 10, but does not disengage from the guide groove 9. Due to the setting of the torsion spring 11, the right half of the folding ladder 13 has a clockwise swinging force, which is convenient for forming a V shape. During the process, the latch 81 disengages from the left pair of positioning holes 10 and moves to the right along the guide groove 9, and finally aligns with the right pair of positioning holes 10. Loosening the control lever 83 can reset the latch 81 and plug it into the right pair of positioning holes 10, completing the shaping of the folding ladder 13. The right end of the folding ladder 13 is against the ground, and after the locked universal wheel 3 is used to improve the placement stability, the frame structure can be climbed for assembly. After the assembly is completed, it can also be used alone to provide an additional working platform.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included within the present invention.
