Description

Technical Field

[0001] This utility model relates to the field of semi-trailer technology, specifically to a reinforcement device for the upright fixing box of a side-tipping semi-trailer, which effectively solves the problem of cracking of the side beam at the upright fixing box. Background Technology

[0002] In the existing technology, the column installation method of side-dump semi-trailers is usually plug-in type: the side beam is cut open (the upper side of the side beam is cut open), and the column fixing box is welded to the inside of the side beam at the cut open. The plug end of the column is directly plugged into the column fixing box.

[0003] Currently, in accordance with the requirements for lightweight side-dumping, the side beams of side-dumping semi-trailers used for standard load transport are mostly made of thin-walled steel. During transportation, due to the diversification of transported goods, when the cargo box expands, the uprights will squeeze the side beams, causing stress concentration at the upper end of the upright fixing box, which often leads to cracking of the side beams at the upper end of the upright fixing box, reducing the overall safety of the vehicle.

[0004] Chinese utility model patent CN201620554556.X discloses a reinforcing mechanism for the side panel post box of a commercial vehicle. The side panel post box is welded at the junction of the side beam of the vehicle body and the crossbeam of the post box, and a horseshoe-shaped reinforcing plate is attached to the top of the outer wall of the post box. This utility model's reinforcing mechanism for the side panel post box of a commercial vehicle, by adding an upward-curved horseshoe-shaped reinforcing plate, makes the side panel post box, the crossbeam of the post box, and the side beam of the vehicle body welded into a whole. The side panel post box is more securely fixed and can withstand the impact of goods and the pressure of the side panel during use, reducing the degree of deformation, cracking, and displacement of the side panel post box. The assembly and disassembly of the side panel posts are also more convenient, and the opening and closing of the side panel is easier. However, the aforementioned patent lacks reinforcement for the side beam, and cannot solve the problem of side beam cracking. Summary of the Invention

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a reinforcement device for the upright fixing box of a side-tipping semi-trailer. This utility model aims to solve the problem of side beam cracking and improve the overall vehicle safety.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a side-tipping semi-trailer column fixing box reinforcement device, including a column fixing box and a side beam. The column fixing box is a vertical U-shaped box structure. The column fixing box is fastened to the inside of the side beam and placed at the cut-out of the side beam. The column fixing box and the side beam are welded together to form a stake for inserting the side box column. The upper end of the column fixing box is equipped with a reinforcing round steel bar, which is bent into a U-shape. The opening direction of the reinforcing round steel bar is opposite to the opening direction of the column fixing box. The middle section of the reinforcing round steel bar is welded to the inside of the side beam. The two bent sections of the reinforcing round steel bar are respectively placed on the two sides of the upper edge opening of the column fixing box and welded together. The reinforcing round steel bar and the upper edge of the column fixing box are closed to form an insertion interface.

[0007] Beneficial effects: This utility model welds a reinforcing round steel bar between the inner side of the side beam and the upper end of the column fixing box. This reinforcing round steel bar not only improves the strength of the side beam at this point, but also enhances the reliability of the connection between the column fixing box and the side beam. Moreover, since the middle section of the reinforcing round steel bar is welded to the inner side of the side beam, when the side box column is inserted into the stake, the reinforcing round steel bar separates the side box column from the side beam, which can prevent the side box column from directly contacting the side beam, reduce stress concentration on the side beam at the upper end of the column fixing box, and thus effectively prevent the side beam from cracking, thereby improving the overall vehicle safety.

[0008] Based on the above, notches are provided on both sides of the upper edge opening of the column fixing box along its length direction, and the two bent sections of the reinforcing round steel are respectively embedded in the notches on both sides of the upper end of the column fixing box.

[0009] Beneficial effect: The notch can accurately locate and reinforce the round steel.

[0010] Based on the above, a reinforcing pad is also welded to the lower inner side of the side beam, located directly below the middle section of the reinforcing round steel. The thickness of the reinforcing pad is the same as the diameter of the reinforcing round steel.

[0011] Beneficial effects: The reinforcing pad can be in the same plane as the middle section of the reinforcing round steel, preventing the side box column from tilting after being inserted into the pile, thus improving the installation stability of the side box column.

[0012] Based on the above, the reinforcing pad is a T-shaped plate.

[0013] Beneficial effects: The T-shaped design of the reinforcing pad reduces its weight and saves materials. Attached Figure Description

[0021] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0022] Example 1 like Figures 1-6 As shown, a side-tipping semi-trailer column fixing box reinforcement device includes a column fixing box 1, a side beam 2 and a reinforcing round steel 3. The column fixing box 1 is a vertical U-shaped box structure. The column fixing box 1 is fastened to the inside of the side beam 2 and placed at the cut-out of the side beam 2. The column fixing box 1 and the side beam 2 are welded together to form a stake for inserting the side box column. The upper edge of the column fixing box 1 has notches 4 on both sides along its length. The reinforcing round steel 3 is set at the upper end of the column fixing box 1. The reinforcing round steel 3 is bent into a U-shape. The opening direction of the reinforcing round steel 3 is opposite to the opening direction of the column fixing box 1. The middle section of the reinforcing round steel 3 is welded to the inner side of the side beam 2. The two bent sections of the reinforcing round steel 3 are respectively embedded in the two notches 4 at the upper end of the column fixing box 1 and respectively welded to the two edges of the upper edge opening of the column fixing box 1. The reinforcing round steel 3 and the upper edge of the column fixing box 1 are closed to form an insertion interface.

[0023] This invention involves welding a reinforcing round steel 3 between the inner side of the side beam 2 and the upper end of the column fixing box 1. This reinforcing round steel 3 not only improves the strength of the side beam 2 at this location but also enhances the reliability of the connection between the column fixing box 1 and the side beam 2. Furthermore, since the middle section of the reinforcing round steel 3 is welded to the inner side of the side beam 2, when the side box column is inserted into the stake, the reinforcing round steel 3 separates the side box column from the side beam 2, preventing the side box column from directly contacting the side beam 2. This reduces stress concentration on the side beam 2 at the upper end of the column fixing box 1, effectively preventing cracking of the side beam 2 and improving the overall vehicle safety.

[0024] Moreover, the design of notch 4 allows for accurate positioning of the reinforcing round steel 3.

[0025] Example 2 Based on Example 1, such as Figures 1-4 The inner lower part of the side beam 2 is also welded with a reinforcing pad 5 located directly below the middle section of the reinforcing round steel 3. The thickness of the reinforcing pad 5 is the same as the diameter of the reinforcing round steel 3, and the reinforcing pad 5 is a T-shaped plate.

[0026] The reinforcing pad 5 is flush with the middle section of the reinforcing round steel 3, preventing the side support column from tilting after being inserted into the pile, thus improving the installation stability of the side support column. Moreover, the T-shaped design of the reinforcing pad 5 reduces its weight and saves materials.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
