Description

Technical Field

[0001] The utility model relates to the technical field of transportation facilities, in particular to a transportation device for large-section I-shaped steel beams. Background Art

[0002] At present, in the process of using electric flat cars to transport materials and components in the processing plant, it is often the case that the components are too long and the length and cross-section of the components are greater than the length of the electric flat car. In this case, if the large-section workpiece is directly placed on the electric flat car for transportation, it is easy for the components to be placed unstable, the components to shake, and the electric flat car to be crushed. This makes it impossible to transport such workpieces, increases the cost of using electric flat cars, reduces work efficiency, and cannot guarantee safety during transportation. Therefore, it is thought that while using the original electric flat car, an auxiliary bracket should be designed to improve its ability to transport long components under the premise of safety. At present, there is no similar product in this industry. Utility Model Content

[0032] The length of the auxiliary bracket 2 is greater than that of the electric flat cart 1 ; by making the length of the auxiliary bracket 2 greater than that of the electric flat cart 1 , the auxiliary bracket 2 can transport longer components, thereby improving utilization efficiency.

[0033] The workpiece securing device 3 includes two symmetrically arranged stoppers 303 connected by cross-section fixing bolts 301. Each stopper 303 is in the shape of a triangular prism with an isosceles right triangle cross-section, with the right-angled sides of the two stoppers 303 facing each other. The use of cross-section fixing bolts 301 facilitates machining, ensuring the stability of the large-section I-shaped steel beam 4 while also making installation and removal easier.

[0034] The auxiliary bracket 2 is connected to the workpiece fixture 3 by bolts. Several bolt holes are evenly spaced on the top surface of the auxiliary bracket 2. The bolt connection between the auxiliary bracket 2 and the workpiece fixture 3 and the evenly spaced bolt holes on the top surface of the auxiliary bracket 2 facilitate flexible placement of the workpiece fixture 3 on the top surface of the auxiliary bracket 2, facilitating the securement of large-section I-shaped steel beams 4 during transportation of varying sizes.

[0035] The bottom surface of the auxiliary bracket 2 is provided with a plurality of vertical limiting rods 202 along the width direction of the electric flat cart 1, and the vertical limiting rods 202 are in close contact with the electric flat cart 1.

[0037] A plurality of lifting ears 201 are symmetrically provided on both sides of the top surface of the auxiliary bracket 2 .

[0038] The auxiliary bracket 2, vertical limit rod 202, and diagonal brace 203 are made of I-beam steel. They are welded together. By using I-beam steel as the material for the auxiliary bracket 2, vertical limit rod 202, and diagonal brace 203, the required load-bearing capacity and rigidity are met, ensuring their integrity and stability.

[0039] Working principle of this utility model: Use status reference Figures 6 to 8 When transporting a large-section I-shaped steel beam 4, first hoist several large-section I-shaped steel beams 4 in parallel and place them on the auxiliary bracket 2, and then arrange the two limiters 303 of the workpiece fixing device 3 at both ends of each large-section I-shaped steel beam 4, as shown in FIG. Figure 6As shown, a number of circular holes 401 are arranged at both ends of the large-section I-shaped steel beam 4 along the height direction, and two limit members 303 are arranged at both ends of the circular holes 401, and are connected by cross-section fixing bolts 301 that pass through the two limit members 303 and the circular holes 401 respectively. At this time, the lower end of the large-section I-shaped steel beam 4 is fixed. In order to ensure the stability of the transportation process, at the upper end of the large-section I-shaped steel beam 4, two or more parallel large-section I-shaped steel beams 4 are connected by cross-section fixing bolts 301 to ensure the stability of the upper end of the large-section I-shaped steel beam 4.
