Description

Brackets for semi-trailer ladders

technical field

The utility model relates to a bracket for a climbing ladder of a semitrailer.

Background technique

There are two kinds of traditional semi-trailer ladders: one is assembled or welded at a certain position of the semi-trailer, such as the front end or the rear end, the position is fixed, the maneuverability is poor, and the ladder itself occupies the size of the semi-trailer, The effective use space of the semi-trailer is limited. The other is a movable ladder, which is lighter in weight, mostly made of aluminum alloy, and is generally pullable. There are two individuals between the ladder and the trailer. The ladder itself does not occupy the overall size of the trailer, and the ladder has good maneuverability, and the ladder can be moved freely as needed. However, it is inconvenient to carry this ladder with the car. A very headache for users.

Therefore, it is still an urgent problem for those skilled in the art to design a bracket on the semi-trailer that can easily place the ladder so that the ladder has good maneuverability and does not occupy the overall size of the semi-trailer.

Utility model content

The problem to be solved by the utility model is to overcome the problem of insufficient placement of the existing semi-trailer ladder, and provide a ladder bracket with a simple structure that does not occupy the space of the semi-trailer.

The utility model provides a semi-trailer ladder bracket, which is a rectangular frame 1 arranged on the lower side of the gooseneck of the semi-trailer. A long side of the rectangular frame 1 and the lower wing plate 2 of the longitudinal beam pass through a hinge 3 connection, the two short sides of the rectangular frame 1 are welded with a fixed iron 4 at the end away from the hinge connection side, and the fixed iron 4 is detachably movable with the wing brace 6 or the through beam under the gooseneck through the bolt 5 Connected, the rectangular frame 1 and the lower portion of the gooseneck form a space that can accommodate a semi-trailer ladder 7 .

According to the bracket of the semi-trailer climbing ladder of the present invention, a plurality of reinforcing ribs 8 are arranged in the transverse direction in the rectangular frame 1 .

According to the bracket of the climbing ladder of the semi-trailer of the present invention, wherein: when the bolt 5 is opened, the frame 1 turns downward around the hinge 3 .

The bracket of the utility model is simple in structure, easy to operate, does not occupy the space of the trailer, and is especially suitable for semi-trailers such as side curtain vans, RVs, exhibition vehicles, etc., and can effectively solve the problem of climbing ladders, and is very practical.

Detailed ways

The utility model will be further described below through specific embodiments with reference to the accompanying drawings, the purpose of which is to facilitate the understanding of the utility model, and is not intended to limit the utility model.

The idea of the utility model is that a bracket is arranged on the lower side of the gooseneck of the semi-trailer for placing the ladder, and the arrangement has a simple structure and does not occupy the external space of the semi-trailer.

As shown in Figures 1 to 3, Figure 1 is a schematic diagram of the bracket of the present invention looking up after the ladder is placed, Figure 2 is a schematic diagram along the direction A-A of Figure 1, and Figure 3 is a schematic diagram of the left side of Figure 1.

The first embodiment of the bracket of the semi-trailer climbing ladder of the present utility model is that the bracket is a rectangular frame 1 arranged on the lower side of the gooseneck of the semi-trailer, and one long side of the rectangular frame 1 is connected with the longitudinal beam lower wing plate 2 The two short sides of the rectangular frame 1 are welded with a fixed iron 4 at the end away from the hinge connecting edge, and the fixed iron 4 is connected with the wing strut 6 or the through beam under the gooseneck through the bolt 5 Being a detachable movable connection, the rectangular frame 1 and the lower part of the gooseneck form a space that can accommodate a semi-trailer ladder 7 .

The second embodiment of the bracket of the semi-trailer climbing ladder of the present invention is that, in the bracket of the first embodiment, several reinforcing ribs 8 are arranged in the horizontal direction in the rectangular frame 1 .

The third embodiment of the bracket of the semi-trailer climbing ladder of the present invention is that, in the bracket of the first embodiment, when the bolt 5 is opened, the frame 1 turns downward around the hinge 3 .

In the fourth embodiment of the bracket of the semi-trailer climbing ladder of the present invention, in the bracket of the second embodiment, when the bolt 5 is opened, the frame 1 turns downward around the hinge 3 .

Specifically, as shown in Figures 1 to 3, when the ladder 7 is placed, one long side of the square frame 1 is connected to the lower wing plate 2 of the longitudinal beam 2 through the hinge 3, and the two short sides of the square frame 1 are away from the hinge. The fixed iron 3 welded on one side of the page connecting edge is connected with the wing strut 6 of the vehicle frame body through the bolt 5, so that a space that can accommodate the ladder is formed above the bracket and under the gooseneck of the semi-trailer.

The utility model uses the space at the gooseneck of the semi-trailer to set the bracket for the climbing ladder. The bracket is connected with the lower wing plate of the longitudinal beam with a hinge, so that the bracket can be turned downward freely. The fixed irons welded thereon are bolted to the wing struts or through-beams of the frame body. The method of using the bracket is as follows: when it is necessary to place a ladder in the bracket, remove the fixing bolts, drop the bracket, put the ladder on the bracket, lift the bracket, and fix the bracket with bolts; When taking out the ladder from the bracket, remove the fixing bolts, drop the bracket, remove the ladder from the bracket, and fix the bracket with bolts.

Through the detailed description of the specific embodiments above, it is hoped that the utility model can be described more clearly, but the preferred specific embodiments disclosed above are not used to limit the utility model. The claims of the present utility model should be interpreted in the broadest way based on the above description, so as to cover all possible changes and arrangements with equivalents.
