The embodiment also comprises a mobile contact net two-end setting structure:

In the embodiment, the supporting mechanisms can drive the carrier rope and/or the contact line to integrally rise; or in the ascending process, the rotary supporting mechanism is used for driving the carrier rope and/or the contact line to move to a working position and be positioned above the rail 5, and at the moment, the pantograph of the freight train can take electricity for working. After the freight train enters the station, the supporting mechanism drives the carrier rope and/or the contact line to rotate to the non-working position or to retract to the non-working position, and then the moving mechanism is used for driving the whole supporting mechanism to descend so as to drive the carrier rope and/or the contact line to descend.

When the gravity compensation devices are used at the two ends of the movable contact net, the height of the gravity compensation devices is lowered along with the two ends of the movable contact net, and in the gravity compensation mechanism, the weight is preferably selected.

Therefore, the carrier rope and/or the contact line can be hidden under the ground, the work of the ground is not hindered, and the problem that the carrier rope and/or the contact line on the movable contact net is easy to touch when the existing goods are loaded and unloaded is completely solved.

The working principle of the sinking type mobile contact net is described in the utility model:

The lifting and descending modes of the supporting mechanism in the embodiment are as follows: the moving mechanism is used for driving the supporting mechanism to ascend or descend; or the height-variable supporting mechanism stretches or shortens to drive the supporting mechanism to ascend or descend.

It should be noted that, for example, the freight train has progressed, and the contact net needs to be removed for loading operation, at this time, the supporting mechanism drives the carrier cable and/or the contact line to move to the non-working position;

during the process of moving the contact line and/or the carrier rope to the non-working position, or after the contact line and/or the carrier rope have moved to the non-working position;

the supporting mechanism is lowered in height, and the horizontal height of the contact line and/or the bearing rope from the rail surface can be not higher than the horizontal height of the bearing rope from the highest position of the freight train; or the contact line and/or the carrier cable can be no higher than the ground or an artificial building base. The contact line and the carrier cable are not only located in the non-working position, but also lowered to make room for space, the conventional method is to move to the non-working position, the upright post, the carrier cable and the contact line still can obstruct loading and unloading operation, and particularly when a gantry crane is needed, the contact line needs to be moved. The utility model provides a sinking type mobile contact net which can wholly descend an upright post, a carrier rope and a contact line and completely avoid the upright post, the carrier rope and the contact line. And provides safety guarantee for loading and unloading operation.

In some cases, the upright posts of the mobile contact net are relatively close to the rails, the mobile contact net moves to a non-working position and is relatively close to the railway carriage, and when goods are loaded and unloaded, the mobile contact net is easy to touch with the carrier ropes and/or contact lines on the mobile contact net. For this reason, as shown in fig. 15, the present embodiment further provides a sinking mobile catenary, which includes a plurality of telescopic columns 16, each of which is provided with a supporting mechanism 2, and the telescopic columns can drive the corresponding supporting mechanism to rise or fall, so that the level of the carrier cable 3 and/or the contact line 4 is variable;
