Problems solved by technology

[0003] However, at present, there are usually few semi-trailer structures for the transportation of dangerous goods. The semi-trailer structures for dangerous goods on the market are generally complex in structure, with a single external structure, and the internal fixed structure cannot form a further shockproof effect against dangerous goods, especially in When the left and right angles of the semi-trailer are different, it is easier to cause loss or damage due to the collision between dangerous goods and the inner wall of the compartment, causing dangerous accidents

Embodiment 1

[0030] Such as Figure 1-9 As shown, the present invention provides a semi-trailer structure for transporting dangerous goods, comprising a box body 1, a vehicle frame 2 and wheels 3, side doors 4 are installed on both sides of the box body 1, and first side doors 4 are installed at both ends of the side door 4. Hinge structure 401, one end of the first hinge structure 401 is equipped with a side door column 402, and one end of the side door column 402 is equipped with a side corrugated board 403, and the upper side of the side corrugated board 403 is provided with a box ventilation hole 404, and the side door 4 A door lock lever 5 is installed on the surface, a bottom beam 6 is installed on the bottom of the side door 4, a rear door 7 is installed on one end of the box body 1, a door lock lever 5 is installed on the surface of the rear door 7, and a second Hinge structure 701, one end of the second hinge structure 701 is equipped with rear door column 702, the bottom end of r...

Embodiment 2

[0042] An air spring 810 is installed on the inner side of the telescopic rod 807, and the air spring 810 is fixedly connected with the movable plate 802 and the groove 806 respectively, and the other structures are the same as in the first embodiment.

[0043] The structure of the overall cargo fastening device 8 is mainly elastically connected by the structure of the air spring 810. Since the structure of the air spring 810 has a stronger limit, better absorption of lateral inertial force, and a simpler connection method, the air spring 810 is used In the structure, after the dangerous goods are fixed to the ground of the box body 1, the interior can produce a large inertial energy absorption effect in the case of shaking, the effect is better than that of the spring plate 808, and the requirement for the overall load capacity is lower.

Abstract

The invention discloses a dangerous goods transportation semitrailer structure which comprises a box body, a frame and wheels; side doors are installed on the surfaces of the two sides of the box body, first hinge structures are installed at the two ends of each side door, side door stand columns are installed at one ends of the first hinge structures, and side corrugated boards are installed at one ends of the side door stand columns. A door lock rod is installed on the surface of each side opening door, a bottom cross beam is installed at the bottom end of each side opening door, a rear door is installed at one end of the box body, a door lock rod is installed on the surface of the rear door, second hinge structures are installed at the two ends of the rear door, and a connecting corner piece is installed at one end of the frame cross beam; a trailer traction device is installed at one end of the inner side of the frame cross beam, and a cargo bolting device is installed in the box body. According to the semi-trailer structure simple in structure, loading and unloading are facilitated under the condition that the overall strength is met, the formed air flowing holes can meet the internal air flowing requirement, the structure is simple, and production is facilitated.

Description

technical field [0001] The invention relates to the field of cargo transportation, in particular to a semi-trailer structure for dangerous goods transportation. Background technique [0002] A semi-trailer is a trailer whose axle is placed behind the vehicle's center of gravity (when the vehicle is evenly loaded) and is equipped with a hitch that transmits horizontal and vertical forces to the tractor. Semi-trailers are generally three-axle semi-trailers, and their types are divided into 11-meter warehouse semi-trailers, 13-meter warehouse semi-trailers, and low-bed semi-trailers. It is a heavy-duty transport vehicle connected to the head of the semi-trailer through the traction pin, and it will be used together with a cargo box if necessary. [0003] However, at present, there are usually few semi-trailer structures for the transportation of dangerous goods. The semi-trailer structures for dangerous goods on the market are generally complex in structure, with a single exte...
