Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe transportation, in particular to a semitrailer steel pipe transportation auxiliary part. Background Art

[0002] A semi-trailer is a trailer with the axle placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. Semi-trailers are generally three-axle semi-trailers, and their types are divided into many categories such as 11-meter warehouse semi-trailers, 13-meter warehouse semi-trailers, and low-bed semi-trailers. It is a heavy-duty transportation vehicle connected to the semi-trailer head through a traction pin. Steel with a hollow cross-section whose length is much greater than the diameter or circumference. According to the cross-sectional shape, it is divided into round, square, rectangular and special-shaped steel pipes; according to the material, it is divided into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes and composite steel pipes; according to the use, it is divided into steel pipes for pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc.; according to the production process, it is divided into seamless steel pipes and welded steel pipes, among which seamless steel pipes are divided into hot rolling and cold rolling (drawing), and welded steel pipes are divided into straight seam welded steel pipes and spiral seam welded steel pipes.

[0003] When transporting steel pipes on a semi-trailer, the steel pipes need to be stably fixed inside the car body. If the fixation is not firm enough, the steel pipes will move, which may cause safety hazards, especially during emergency braking. Most existing fixing methods usually use straps for auxiliary fixation. The straps themselves have a certain elasticity and can effectively protect during slight shaking. However, the fixing effect of the steel pipes is still poor during high-speed uphill and emergency braking. For this reason, we propose a semi-trailer steel pipe transportation auxiliary part.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figures 1 to 5 The utility model provides a technical solution: a semi-trailer steel pipe transportation auxiliary part, including a chassis 1, a support frame 4 is fixedly mounted on the outer side of the chassis 1, a bottom tray 10 is placed on the top of the chassis 1, and an arc groove is provided on the top of the bottom tray 10 and the upper and lower sides of the support tray 11, and a friction pattern is provided on the inner side of the arc groove. The friction pattern increases friction during use, which can ensure that the steel pipe has sufficient friction and prevent the steel pipe from moving and causing safety hazards. At the same time, the setting of the support frame 4 can limit the left and right movements of the bottom tray 10 and the support tray 11 to ensure the safety of use. The gravity of the steel pipe itself will give the steel pipe and the bottom tray 10 and the support tray 11 sufficient friction. The bottom surface of the bottom tray 10 is fixedly connected with a positioning The inner movable sleeve of the column 9 and the support frame 4 is provided with a support tray 11, and the upper and lower layers of the support trays 11 are distributed at intervals, and a steel pipe is placed between the two layers of the support trays 11, and the steel pipe is placed inside the arc groove, and the steel pipe is placed on the top of the bottom tray 10, so that the steel ring is placed inside the arc groove, and then the bottom tray 10 is placed on the top of the steel pipe, so that the bottom tray 10 is at a position between two appropriate limit rods 12, and the steel pipes and the support tray 11 are stacked in turn, and arc grooves are respectively provided on the top of the bottom tray 10 and the upper and lower surfaces of the support tray 11, and a positioning groove 3 adapted to the positioning column 9 is provided on the top of the chassis 1, so that the bottom tray 10 and the support tray 11 are staggered, which can play a role in auxiliary stacking, facilitate the use of the equipment, and improve the practicability of the equipment.

[0022] The inner side of the support frame 4 is supported by a fixed electromagnetic block 8 near the top. Both ends of the bottom tray 10 and the support tray 11 are fitted on the outer side of the limit rod 12. The height of the limit rod 12 is less than the height of the support frame 4. After the fixed electromagnetic block 8 and the movable electromagnetic block 7 are powered on, the magnetic poles of the fitting surfaces of the movable electromagnetic block 7 and the fixed electromagnetic block 8 are the same. The fixed electromagnetic block 8 is fixed inside the support frame 4, and the movable electromagnetic block 7 will be pushed to move outward. At the same time, the movable electromagnetic block 7 will drive the isotope plate 6 and the movable block 5 to move outward during the movement, so that the movable block 5 moves outward inside the movable slot 2, so that the fixed electromagnetic block 8 and the movable electromagnetic block 7 can move forward and backward. They are parallel to each other so that the fixed electromagnetic block 8 and the movable electromagnetic block 7 are located in the middle position near the isotope plate 6. A movable groove 2 is opened inside the chassis 1 near the left and right walls. The movable block 5 is movably sleeved inside the movable groove 2. The horizontal cross-section of the movable block 5 is T-shaped. A support member is provided near the upper portion of the isotope plate 6 so that the support member passes through the support frame 4 and extends to the inner side of the support frame 4 to the inside of the support frame 4. In conjunction with the movable block 5, the stable movement and range of movement of the isotope plate 6 can be limited. The outer side of the movable block 5 is fixedly connected to the isotope plate 6, the inner side of the isotope plate 6 is fixedly sleeved with the movable electromagnetic block 7, and the inner side of the isotope plate 6 is fixedly installed with a limiting rod 12.

[0023] In summary, when the semi-trailer steel pipe transportation auxiliary part is used, first when loading, the fixed electromagnetic block 8 and the movable electromagnetic block 7 are controlled to be energized, so that the magnetic poles of the fitting surfaces of the movable electromagnetic block 7 and the fixed electromagnetic block 8 are the same, and the fixed electromagnetic block 8 is fixed inside the support frame 4. The movable electromagnetic block 7 will be pushed to move outward. At the same time, during the movement of the movable electromagnetic block 7, the isotropic plate 6 and the movable block 5 will be driven to move outward, so that the movable block 5 moves outward inside the movable groove 2. When the isotropic plate 6 moves outward, it will synchronously drive the limit rod 12 to move outward, and then the bottom tray 10 is placed on the top of the chassis 1, and the positioning column 9 is used to cooperate with the positioning groove 3 to complete the positioning of the positioning groove 3. After positioning, place the steel pipe on top of the bottom pallet 10 so that the steel ring is placed inside the arc groove, and then place the bottom pallet 10 on top of the steel pipe so that the bottom pallet 10 is at a suitable position between two limit rods 12, and stack the steel pipe and the support pallet 11 in turn. After stacking, control the fixed electromagnetic block 8 and the movable electromagnetic block 7 to adsorb, so that the movable electromagnetic block 7 drives the isotropic plate 6 and the movable block 5 to move toward the chassis 1, so that the isotropic plate 6 pushes the limit rod 12 to move to both sides of the support pallet 11, and fix the support pallet 11. The cooperation between the support pallet 11 and the bottom pallet 10 during driving can avoid any movement of the steel pipe.
