The existing trestle for shoal loading and unloading operation is generally formed by adopting an integral or all-steel structural type buoyancy tank, and the buoyancy tank is of an integral structure, so that the shortcoming that the existing trestle needs to occupy a large space scale when being stored and assembled, influences the loading space of a landing ship, and if the requirement of the loading space is met, the floatability and stability of the assembled trestle cannot guarantee the operation requirement.

Disclosure of Invention

In view of this, the present invention provides an inflatable shoal trestle system, which can realize longitudinal connection and transverse folding and unfolding, and meet the requirements of space during transportation of the trestle and floatability and stability during unloading and landing operations.

An inflatable shoal trestle system comprises an inflatable folding trestle, an amphibious operation vehicle and an anchorage unit;

aerify folding trestle is formed by a plurality of bridge sections longitudinal connection, the bridge section is folding on horizontal before going out of the cabin, the amphibious operation car is aerifyd the bridge section when will aerify folding trestle soft traction income water, and the bridge section is expanded on horizontal, the both ends of aerifing folding trestle overlap joint landing ship springboard and beach respectively, the anchorage unit will aerify folding trestle and fix on the beach.

Furthermore, the bridge section is formed by transversely connecting a bridge section middle box and a left bridge section side box and a right bridge section side box, the bridge section side boxes can be transversely folded and unfolded, and air bags are arranged at the bottom and the outer sides of the bridge section side boxes.

Furthermore, a hydraulic unit and an electric unit are integrated in the bridge section middle box, and the bridge section side box is folded and unfolded transversely relative to the bridge section middle box through the matching of the hydraulic unit and the electric unit.

Has the advantages that:

1. the trestle of the invention is formed by adopting unit modularized transversely foldable and longitudinally spliced bridge section buoyancy tanks, and the folded bridge section can meet the requirements of transportation size and weight.

2. The bottom and the outer side of the two sides of the bridge section are provided with the air bag retraction devices, the air bag retraction devices are retracted into the contour of the bridge section during folding, and sufficient buoyancy and stability guarantee are provided for the trestle during expansion and inflation.

3. The bridge section of the invention adopts the hydraulic self-unfolding and folding technology for transverse unfolding and folding, and has high degree of automation, safety and reliability.

The foldable air-filled trestle comprises a 1-inflatable folding trestle, a 2-anchorage unit, a 3-amphibious operation vehicle, a 4-middle bridge section, a 5-end bridge section, a 6-springboard, a 7-middle bridge section box, an 8-side bridge section box and a 9-air bag.

Detailed Description

The invention is described in detail below by way of example with reference to the accompanying drawings.

As shown in the attached figure 1, the invention provides an inflatable shoal trestle system, which comprises an inflatable folding trestle 1, an anchorage unit 2 and an amphibious work vehicle 3;

the inflatable folding trestle 1 is formed by longitudinally connecting a plurality of bridge sections, the bridge sections are folded in the transverse direction before going out of the cabin, the amphibious operation vehicle 3 inflates the bridge sections while softly drawing the inflatable folding trestle 1 into water, the bridge sections are unfolded in the transverse direction, two ends of the inflatable folding trestle 1 are respectively lapped on a landing ship springboard and a beach, the inflatable folding trestle 1 is fixed on the beach by the anchorage unit 2, and the total length of the inflatable folding trestle 1 is about 30 meters.

As shown in fig. 2, the inflatable folding trestle 1 is formed by longitudinally connecting two middle bridge sections 4 positioned in the middle and two end bridge sections 5 positioned at two ends, the bridge sections are longitudinally connected through joints, and the outer ends of the end bridge sections 5 are provided with springboards 6 capable of being longitudinally unfolded and retracted, and the springboards are used for lapping landing ship springboards or lapping beaches and are unfolded and retracted through a springboard overturning mechanism.

As shown in figures 3 and 4, each middle bridge section 4 and end bridge section 5 is formed by transversely connecting 1 bridge section middle box 7 and a left bridge section side box 8 and a right bridge section side box 8, wherein a transverse unfolding and folding mechanism is arranged between the bridge section middle boxes, and the bridge section side boxes 8 can be transversely folded and unfolded, and the folded state is shown in figure 3. The bottom and the outer side of the bridge node side box 8 are provided with air bags 9, the air bags 9 are inflated after the bridge node side box 8 is unfolded, and the unfolded state is shown as figure 4. And the inflation, hydraulic and electric systems are arranged in the

bridge sections

4 and 5 of the trestle unit and inside the amphibious working vehicle 3.

The operation process of the invention is as follows:

two groups of middle bridge sections 4 and two groups of end bridge sections 5 are longitudinally connected in advance in the cabin of the landing ship to form the inflatable folding trestle 1. After landing on a ship, the amphibious working vehicle 3 goes out of the cabin to reach the beach, the lower hoe is fixed on the beach, the traction cable is connected with the front end of the inflatable folding trestle 1, the inflatable folding trestle 1 goes out of the cabin through soft traction, and the inflatable folding trestle 1 gradually enters water after landing on a ship springboard. After entering water, the middle bridge section 4 at the water side and the bridge section side box 8 at the end bridge section 5 are transversely unfolded, and the air bags 9 at the bottom and the outer side of the bridge section side box 8 are inflated to the target pressure. Then the bridge segment side boxes 8 of the middle bridge segment 4 and the end bridge segment 5 on the shore side are transversely unfolded, and the air bags 9 at the bottom and the outer side parts of the bridge segment side boxes 8 are inflated. And finally, longitudinally unfolding the springboards 6 of the bridge sections 5 at the two ends, and respectively overlapping the landing ship springboard and the beach. The amphibious operation vehicle 3 shifts, the anchorage unit 2 is arranged in a matched mode to fix the inflatable folding trestle 1, and the equipment vehicle is carried through after the systems are checked to be in place.

In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
