Description

Scaffolding installation structure for truck loading and unloading

The present invention relates to a scaffolding installation structure for loading and unloading freight trucks, and more specifically, a fixed staircase that is fixed to the rear of the freight truck loading box and is configured to be folded and folded to be used when loading and unloading a cargo box and to be folded at the bottom of the loading box for loading and unloading freight trucks. It relates to a scaffold installation structure.

The loading compartment of the lorry consists of two sidegate assemblies, one reargate assembly and the bottom of the loading compartment, the gate is connected to the sideside rail assembly, the blower is nailed to the cross-follower joist, It is enclosed in a round-shaped side-sight rail attached to the cross-follower joist.

In addition, the height of the loading box varies depending on the type of vehicle, but is to maintain a constant height from the ground.

When loading and unloading cargo in a freight car, a person goes up and down to the loading box for handling of the cargo bar.

The conventional method of lifting and exiting the loading box is a method of climbing and lowering the loading deck by stepping on a small footrest formed on the deck or the vehicle body of the vehicle, but it is difficult for a person with a high height of the loading box and a small person or obese person. There is a risk of a safety accident.

In addition, since the footrest attached to the vehicle body is fixedly exposed to the vehicle body, it has a close relationship with safety while driving the vehicle, and thus is limited in size and position, so that it is insufficient in size to be safe and easy to use.

The technical problem to be achieved by the present invention is to provide a structure of the scaffold which can be used to expand and lower the person to easily step on and off the stowage and the outside of the vehicle can be folded and used when the vehicle is developed and used outside when the problem is solved.

The configuration for achieving the technical problem to be achieved by the present invention, one end is fixed to the bottom of the loading box to be rotated and the other end is the first coupling stage is slidably coupled to the first scaffold plate side, the side of the first coupling stage One end is pivotally coupled and the other end is a first support that is pivotally fixed to the bottom of the loading box, the side is slidingly coupled with the outer end of the first coupling, the inner end is pivotally coupled with the second coupling and the outer end The first scaffold having a restraining portion for restraining the sliding coupling portion, one end is pivotally coupled to the inner end portion of the first scaffold and the other end is a second coupling rod slidably coupled to the side of the second scaffold plate, One end is coupled to the side of the two coupling stage to be rotated and the other end is coupled to be rotated coaxially with the first coupling stage coupled to the first scaffold plate side 2 supports, the side consists of a second scaffold to be rotated with the second engagement one outer end a Sliding bond.

Hereinafter, the detailed description will be given with reference to the accompanying drawings.

One end is fixed to the bottom of the loading box (10) to be rotated by the hinge 21 and the other end of the first coupling table 20 is slidably coupled to the guide groove 80 provided on the side of the first scaffold plate (60) And, one end is slidably coupled to the guide groove 80 formed on the side of the first coupling table 20 and the other end is fixed to be rotated by a hinge 41 on the bottom of the loading box 10, the first coupling table The first support 40 to restrain the deployment angle of the (20) to prevent the folding of the first coupler, the guide groove 80 provided on the side is slidably coupled to the outer end of the first coupler 20 The inner end is pivotally coupled to the inner end of the second coupler 30 and the hinge 61, the end of the guide portion provided on the outer end is a spring in the lower portion of the groove 91 formed perpendicular to the guide groove 80 The ball 92 is provided with the ball of the ball 92 and the ball 93 is protruded by the reaction force of the spring 92 so that the first coupling part 20 and the second support part 50 are coupled to each other. The first footrest 60 is provided with a restraining portion 90 that restrains the engaging portion from flowing out after passing through the ball 93 protruding from the slide, one end of which is hinged with the inner end of the first footplate 60. The second coupling table 30 is pivotally coupled to the 61 and the other end is slidably coupled to the guide groove provided on the side of the second scaffold plate 70, one end of the second coupling table 30 The slide is coupled to the sliding and the other end is coupled to be rotated in the same axis and the first coupling table 20 coupled to the guide groove provided on the side of the first scaffold plate 60 of the second coupling table 30 A second support for supporting the first foot plate 60 and the second foot plate 70 to restrain the deployment angle, and the guide groove provided on the side slides with the outer end of the second coupler. Composed of a second scaffold plate 70 is formed so that people can step on The.

Hereinafter will be described with respect to the operation.

When a person rises and falls in a cargo vehicle loading box equipped with the present invention, when the handle provided in the second scaffold plate 70 is pulled out, the second scaffold plate 70 is pulled out to protrude forward and is coupled with the sliding rod. The second coupler 30 is slid along the guide groove provided on the side of the second scaffold plate 70 and is rotated to be hooked to the end of the guide groove 80 to draw the first scaffold plate 60. ) And the first scaffold plate 60 also protrudes to the front by pulling force. By the above-described action, the first coupling table 20 is also protruded forward by force, so that the footrest protrudes forward.

In addition, when looking at the role of the support to combine the scaffolding and the coupling bar, restrain the angle between the coupling and the footrest to determine the distance between the footrest and the role of preventing the folding or floating of the coupling bar by being transferred to the coupling vertically. The foot plate is fixed, not floating, to keep it safe when a person steps on and climbs into the stack.

The effect of the invention is that it can be deployed outside when used and does not protrude to the outside of the vehicle when folded during operation and does not interfere with driving, and it can be easily and safely stepped up and down to the loading box to prevent safety accidents. There is.
