Abstract
Description
Technical Field
[0001] The utility model relates to a semitrailer, in particular to a multifunctional low-bed semitrailer. Background Art
[0002] A semi-trailer is a special trailer transporter. When in motion, the gooseneck at the front of the vehicle body is placed on the traction plate (responsible for traction and steering) at the rear of the main tractor. The mass of the front of the vehicle body is supported by the rear axle of the tractor, and the mass of the rear of the vehicle body is supported by the axle of the trailer itself.
[0003] At present, most of the low-bed semi-trailers in China are special vehicles for transporting large goods, and the vehicle load-bearing surface is a single flatbed without other structures. The vehicle utilization efficiency is low, especially it cannot meet the requirements put forward by some countries and regions in the world that low-bed semi-trailers can transport various forms of goods. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a multifunctional low-bed semi-trailer. After the utility model is applied, various goods in different forms can be transported and the vehicle utilization efficiency is high.
[0005] In order to solve the above technical problems, the utility model discloses a multifunctional low-bed semi-trailer, comprising a frame, a goose neck at the front part of the frame, a cargo support part at the rear part, I-shaped side beams at the upper left and right sides of the cargo support part, and a flat plate is laid between the I-shaped side beams at the left and right sides, characterized in that: rotating supports are evenly spaced and installed on the outer sides of the I-shaped side beams at the upper left and right sides of the cargo support part, the rotating supports include a fixed shaft fixed to the outer sides of the I-shaped side beams and a supporting plate rotatably mounted on the fixed shaft, a limiting baffle extending upward is fixed to the outer end of the supporting plate, the supporting plate can be rotated around the fixed shaft to the outer side of the I-shaped side beam in an expanded state or rotated to abut against the I-shaped side beam in a retracted state; it also includes an extended pad, when the supporting plates at the outer sides of the left and right I-shaped side beams are in an outwardly expanded state, the extended pad can be laid on the supporting plates on both sides, and the outer sides of the extended pad abut against the limited baffle.
[0006] After the utility model adopts the above structure, when the rotating support is in the unfolded state and the extended pad is laid on the rotating support, it is equivalent to increasing the width of the cargo support part at the rear of the frame, which can increase the amount of cargo transportation and meet the transportation needs of some foreign countries.
[0007] As an improvement of the utility model, a cargo box surrounded by railings is provided above the goose neck.
[0008] After adopting the above technical features, the transportation function of the utility model is further expanded, and some bulk goods can be conveniently transported.
[0009] Furthermore, pile seat covers are installed on the left and right sides of the flat plate.
[0010] After adopting the above technical features, when transporting long goods, limiting rods can be inserted into the pile seat covers on both sides to prevent the long goods from sliding out to the sides.
[0011] Furthermore, anti-slip strips are evenly spaced and fixed on the left and right side surfaces of the flat plate.
[0012] After adopting the above technical features, long goods can be further prevented from sliding out to the sides.
[0013] Furthermore, pull rings are evenly spaced on the outer sides of the I-shaped side beams on the left and right sides of the upper part of the cargo supporting part, and pull rings are also installed on the rear side wall of the goose neck at the front part of the frame.
[0014] After adopting the above technical features, the cargo on the cargo support part can be tied up by passing ropes through each pull ring, so that the cargo on the cargo support part can be better fixed. BRIEF DESCRIPTION OF THE DRAWINGS
