Description

[Detailed description of the invention] [Industrial field of application] This invention relates to an improvement of a trailer used for transporting construction machinery, etc.

[Prior Art] Conventional trailers of this type have an almost flat floor on which the construction machinery and the like of the main body, which can be driven by wheels, is loaded, and therefore, especially in large construction vehicles, the floor from the ground to the bottom is flat. The height from the ground is very high, and when loaded onto the floor of the main body of the trailer, there is a risk that the maximum height from the ground will exceed the height stipulated by the Road Traffic Act.

[Purpose of the invention] This invention was devised in view of the above-mentioned circumstances, and its purpose is to place vehicles, etc. loaded on the surface of the loading platform of the main body, which can be driven by wheels, on the loading platform. A recess into which a wheel can be inserted is formed, a lid is removably attached to the recess, through-holes communicating with each other are formed in the recess of the lid and the main body, and both of the through-holes A pin with a male thread at the tip is installed so that it can be inserted and removed, and a female thread is screwed to the male thread of the pin, so even when loading construction vehicles with high overall height, To provide a trailer whose maximum height can be within a specified range.

[Example] An example of this invention will be described below based on the accompanying drawings.

Figures 1 and 2 are a side view and a plan view of a trailer according to this invention.
The main body is equipped with a connecting member 3 that can be connected to a driving vehicle (tractor) and legs 4 that can be moved in and out on both sides. A substantially flat loading platform 6 on which a construction vehicle 5 is loaded is formed substantially in the center. On the surface of this loading platform 6, a total of four recesses 7 into which the wheels 5a of the construction vehicle 5 can be inserted are formed on both sides at regular intervals in the front and rear.

As shown in FIGS. 3 and 4, the recess 7 is
A main rail 8 and a side rail 9 that are long in the front-rear direction and constitute a part of the loading platform 6, and a pair of outriggers 10 that are installed between the main rail 8 and the side rail 9 at a constant distance in the front and back. A plate-shaped upper plate 11 is fixed to the upper plate, which has the recess 7 formed therein, and is bent downward into a trapezoidal shape. A lower plate 12 having a shape is fixedly attached thereto. A pair of longitudinally long ribs 13 are formed between the upper plate 11 and the lower plate 12 at regular intervals. In addition, a pair of through holes 14 and 15 are formed in the upper plate 11 and the lower plate 12, respectively, at a constant interval in the left and right directions and approximately at the center in the front-rear direction. These pair of through holes 14 and 15 are connected by a pipe body 16, respectively.

As shown in FIGS. 5 and 6, the recess 7 includes a flat portion 1 whose longitudinal section is trapezoidal facing downward and whose upper portion is substantially flush with the surface of the loading platform 6.
A pair of wooden lids 18 having a diameter of 7 are inserted removably and substantially parallel to each other. Each floor 18 has
A recess 19 is formed in each of the flat parts 17, and a through hole 20 that can communicate with the through holes 14 and 15 is bored in the center of each recess 19, respectively. As shown in FIGS. 7 and 8, these through holes 20 each have a pin having a male threaded portion 21 formed at the lower part and a ring-shaped grip 22 pivotally supported at the upper part so as to be able to swing as shown by the arrow. 23 is penetrated from above, and a female threaded body 24 formed by a nut or the like is screwed to the penetrated male threaded portion 21 of the pin 23, and the floor wood 18 is inserted and fixed in the recessed portion 7.

[Effects of the invention] As described above, according to the trailer according to this invention, when the construction vehicle 5 is loaded on the loading platform 6 and transported, as shown in the first figure, the female threaded body 24 is Remove the pin 23 from the male threaded part 21, and
3 from the through holes 14, 15, 20 and each floor wood 18 from the recess 7, the wheels 5a of the construction vehicle 5 are inserted into the recess 7.
This has the effect of allowing the overall height to be lowered and within the regulations of the Road Traffic Act. In this case, the through holes 14 and 15 are used as drainage holes for rainwater or the like that enters the recess 7.

In addition, when transporting ordinary machinery or small construction machinery, etc., the floor wood 18 is inserted into the recess 7, and the pins 2 are inserted into the through holes 20, 14, 15.
3 and screwing the female threaded body 24 to the male threaded portion 21 thereof, the floor wood 18 can be fixed to the recess 7, and the surface of the loading platform 6 can be made substantially flat, thereby preventing the transportation from being hindered. It has the effect that there is no problem.
