Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe transportation, in particular to an anti-falling fixing device for steel pipe transportation. Background Art

[0002] Steel pipes have hollow cross-sections and are divided into round, square, rectangular and special-shaped steel pipes according to their cross-sectional shapes; they are divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes according to their materials; they are divided into steel pipes for conveying pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc. When steel pipes are transported, they are easy to slip off the truck due to their arc-shaped and relatively smooth surface. Therefore, fixing devices are often used to fix them. With the development of science and technology, the types of such fixing devices have also increased, making them more convenient to use.

[0003] In view of this, Chinese patent number CN220220548U proposes an anti-falling fixing device for steel pipe transportation. The utility model sets two sets of protection components respectively installed at the front and rear parts of the carriage, and places the steel pipe to be transported between the two sets of protection components. When the steel pipe slides forward and backward due to inertia during vehicle transportation, the end of the steel pipe is pressed against the outside of the movable plate, and the movable plate is pushed to slide along the length direction of the support rod. The spring is used to buffer the sliding impact force of the steel pipe to prevent the steel pipe from rushing out of the carriage, making the transportation more stable and practical.

[0004] However, although the above technical solution arranges protective components at the front and rear ends of the steel pipe during transportation, so that the steel pipe is blocked from sliding back and forth, the repeated back and forth sliding of the steel pipe on the fixing device can easily cause surface wear and cause more scratches on the surface, affecting the overall quality of the steel pipe and reducing the protectiveness of the device to the steel pipe. In this regard, the present design proposes an anti-falling fixing device for steel pipe transportation. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide an anti-falling fixing device for steel pipe transportation to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model proposes an anti-falling fixing device for steel pipe transportation, comprising a support frame and a fixing mechanism installed on the top of the support frame;

[0007] The fixing mechanism includes limiting slide grooves opened on both sides of the top of the support frame, and movable brackets are slidably provided at both ends of the inner walls of the two limiting slide grooves, and two rotating shafts are rotatably provided between the four movable brackets. The outer walls of the two rotating shafts are fixed with support bars at equal distances, and the outer wall of one end of each support bar is rotatably provided with a limiting cover, and the inner wall of each limiting cover is fixed with a first protective pad, and one side of each limiting cover is threadedly connected with a fixing buckle through the inner wall of the support bar.

[0008] In one example, the tops of the two movable brackets are each provided with an adjustment slot, and one end of the two rotating shafts passes through the inner wall of the adjustment slot and is connected with a screw.

[0009] In one example, sleeves are sleeved on the outer walls of the two screw rods, and the inner walls of the two sleeves are respectively threadedly connected to the outer walls of the two screw rods, and rotating handles are fixed on the tops of the two sleeves.

[0010] In one example, a connecting groove is opened on one side of the outer wall of the support frame, and the inner wall of the connecting groove is connected to the inner wall of one of the limiting sliding grooves, wherein the lower ends of one side of the two movable brackets are threadedly connected with fixing bolts through the inner wall of the connecting groove.

[0011] In one example, the top of the support frame is provided with slots at equal distances, and a second protective pad is fixedly provided on the inner wall of each slot.

[0012] In one example, support rods are fixedly provided at the four corners of the top of the support frame, and limiting grooves are provided at the four corners of the bottom of the support frame.

[0013] The anti-falling fixing device for steel pipe transportation proposed by the utility model can bring the following beneficial effects:

[0014] The invention discloses an anti-falling fixing device for transporting steel pipes. The fixing mechanism is arranged on a supporting frame. When fixing the steel pipe, a movable bracket is slid in a limiting slide groove to adjust the distance between the fixing mechanisms according to the length of the steel pipe. Then, the rotating shaft is rotated to make the limiting covers cover the two ends of the steel pipe to limit and squeeze it. Then, the sleeve is rotated to be tightened on the screw rod and squeezed on the top of the movable bracket to prevent the rotating shaft from rotating. In this way, during the transportation process, the steel pipe will not slide back and forth due to inertia, resulting in the surface of the steel pipe being damaged by friction with the truck, thereby improving the protection of the device to the steel pipe.
