Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention leans on a machine with a caterpillar when loading or unloading a machine for transporting machines such as trucks and vehicles, ships, etc. for transporting the machine. The present invention relates to a bridge for loading and unloading a machine with a track, which enhances safety and facilitates operation of the machine with a track.

[0002]

2. Description of the Related Art Conventionally, when a machine with a caterpillar such as a combine, a rice reaper, and a bulldozer is loaded or unloaded on, for example, a truck, a bridge which is used by leaning against the bed of the truck is used as shown in FIG. The loading and unloading bridge that was formed in a straight line from the ground to the bed was used.

However, when a conventional straight loading / unloading bridge is used, for example, when loading a construction machine with a caterpillar on a truck, the ground portion of the caterpillar of the construction machine is a straight line, so that the front portion of the construction machine is In some cases, the ground surface of the truck was hurt hard from the floating state, the floor surface of the truck was damaged, or the truck shook violently, which was dangerous to the operator of the construction machine. Especially when using a straight loading and unloading bridge when unloading construction equipment, the grounding part of the caterpillar of the construction equipment is straight, so the front of the construction equipment floats when landing after transferring from the truck to the bridge. Therefore, it was necessary to control the speed of the construction machinery and carry out careful operation in order to make contact with the upper surface of the bridge. That is, when the driving operation is incomplete, a large impact may be applied to bend the bridge.

[0004]

Therefore, the bridge for loading and unloading the caterpillar machine, which does not cause such a problem, facilitates the operation of the caterpillar machine, and can safely perform the loading and unloading work of the caterpillar machine. Therefore, it is an object of the present invention to provide a loading / unloading bridge for such a caterpillar machine.

[0005]

In order to achieve the object, the bridge for loading and unloading of a machine with a caterpillar of the present invention has a bridge portion on the side of leaning against the bed of a transportation machine in an arcuate portion. Is characterized by.

Further, the length of the arcuate portion is 1/4 to 1/5 of the total length of the bridge.

Further, the distance between the virtual tip position and the tip position formed in the arcuate portion when the bridge portion on the side of the transportation machine is leaning straight is about 8 cm.
It is characterized in that the arcuate portion is formed so as to be 18 cm, more preferably 10 cm to 15 cm.

Further, the total length of the loading / unloading bridge of the machine with caterpillar is 210 cm to 380 cm, and the length of the arcuate portion is 42 cm to 95 cm.

Aluminum, iron, etc. can be used as the material, but aluminum is preferable because it is lightweight.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail below with reference to the drawings showing the embodiments of the present invention. FIG. 1 is a schematic view showing a state in which a loading / unloading bridge of a machine with a caterpillar according to the present invention is used for a truck, 1 is a bridge of the present invention, 2 is a linear portion of the bridge, and 3 is a part of the bridge. This is an arcuate portion, and shows a state in which the bridge is leaned against the truck on the loading platform 4 of the truck with an inclination angle of α to the ground 5. Here, the total length of the bridge 1 is usually 210 cm to 38
Although it is about 0 cm, the length a of the linear portion 2 and the length b of the arc portion 3 are preferably b / (a + b) = 1/4 to 1/5.
Further, the distance c between the virtual tip position and the tip position formed in the arcuate portion when the entire bridge is straightened up to the side where it is leaned against the loading platform such as a truck is about 8 cm to 18 cm, more preferably 10 cm to It is preferable to form the arcuate portion so as to have a length of 15 cm, because the construction machine with the caterpillar can be easily operated and the safety can be improved when the construction machine with the caterpillar is loaded and unloaded on the truck. Furthermore, if a rubber plate or the like is laminated on the upper surface of the bridge, slip resistance and technical action can be obtained, which is more desirable.

When the bridge is used by resting it on a loading platform 4 such as a truck, the inclination angle α with the ground 5 is usually 1
It is generally about 5 °, but it is slightly larger in the case of the bridge of the present invention. Normally, it can be used as it is, but depending on the type of caterpillar machine, if the front end of the machine comes into contact with the bridge when it starts to climb up to the bridge, a plate should be placed on the extension of the bridge toward the ground. Etc. should be placed.

FIGS. 2 and 3 are explanatory views showing an example in which a circular arc portion is about ⅕ and ⅕ of the entire length of a bridge having a length of 350 cm.

[0013]

EXAMPLE When the loading / unloading bridge of the machine with a caterpillar of the present invention is used, the caterpillar naturally contacts the circular arc portion of the bridge, in other words, the contact area increases,
When loading machinery such as construction machinery with a track on a transportation machine such as a truck, the construction machinery gently touches the floor surface of the truck, etc., and when unloading the construction machinery from the truck, etc. Gently touches the floor of the bridge.

[0014]

The loading / unloading bridge of the caterpillar machine of the present invention facilitates the operation of the caterpillar machine when loading or unloading the caterpillar machine on the bed of the transport machine. Moreover, the safety can be sufficiently secured without damaging the floor surface or bridge of the transportation machine.
