Description

Technical Field

[0001] This utility model relates to the field of barges, specifically to an electric towed large barge. Background Technology

[0002] Currently, large barges are used for ferry crossings on inland waterways in China to connect the two sides of the river. These large barges mainly have flat decks, allowing vehicles to drive directly onto the deck, and are propelled by a propeller at the stern. Because they rely on the propeller for propulsion, these existing barges primarily move forward, requiring frequent turns when traveling back and forth between the two banks. During the dry season when the river level is shallow, the propellers often strike rocks on the riverbed, causing damage. Summary of the Invention

[0003] To address the problems of existing technologies, this invention provides an electrically towed large barge. The main objective of this invention is to solve the problem that current river-crossing barges cannot pass under certain conditions. When the river level is shallow, ordinary barges powered by propellers cannot pass, while the electrically towed (with a towing winch) large barge can achieve a minimum draft of 50-60cm, effectively solving the problem of river passage during the dry season. Furthermore, the electrically towed large barge does not need to turn around when traveling back and forth between the two banks, reducing the danger of water flow impact during turning.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An electric towing large barge includes a riverbank A, a riverbank B, an anchoring assembly, and a hull. A river channel C is formed between riverbanks A and B. The anchoring assembly is vertically fixed to riverbanks A and B and is connected to the hull via a towing wire rope, which drives the hull to move within the river channel C. A towing winch is fixedly installed on the hull, and a towing wire rope is connected to the towing winch. The towing wire rope passes through a guide frame installed at the end of the hull, and the tail end of the towing wire rope is anchored to an anchoring pier installed on the riverbank.

[0006] The preferred anchoring assembly includes an anchor block, which is fixed at point A on the riverbank;

[0007] Anchor pier 2 is fixed at point A on the riverbank, and is located on one side of anchor pier 1;

[0008] Anchor pier three is fixed at point B on the riverbank.

[0009] Anchor pier four is fixed at point B on the riverbank and is located on one side of anchor pier three.

[0010] The straight line a containing anchor pier 1 and anchor pier 2 is parallel to the straight line b containing anchor pier 3 and anchor pier 4.

[0011] The straight line 3c containing anchor pier 1 and anchor pier 3 is parallel to the straight line d containing anchor pier 2 and anchor pier 4.

[0012] The preferred traction wire rope includes:

[0013] One end of the steel wire rope is fixedly connected to the anchor block, and the other end of the steel wire rope is connected to the winch on the hull.

[0014] One end of the second wire rope is fixedly connected to the third anchor block, and the other end of the second wire rope is connected to the second winch on the hull.

[0015] One end of the steel wire rope is fixedly connected to the anchor block four, and the other end of the steel wire rope is connected to the winch three on the hull.

[0016] One end of the steel wire rope is fixedly connected to the second anchor block, and the other end of the steel wire rope is connected to the fourth winch on the hull.

[0017] A traction winch is preferably arranged on the hull. The traction winch includes a winch fixed to one corner of one side of the hull; a steel wire rope is connected to the winch.

[0018] Winch 2 is fixed to another corner of one side of the hull, and wire rope 2 is connected to winch 2.

[0019] Winch 3 is fixed to one corner of the other side of the hull, and wire rope 3 is connected to winch 3.

[0020] Winch 4 is fixed to the other corner of the hull on the other side, and wire rope 4 is connected to winch 4.

[0021] The preferred guide frame consists of a main frame, vertical rollers, and horizontal rollers. The main frame is fixed to the hull. Two vertical rollers are installed on one side of the guide frame and are arranged side by side. Two horizontal rollers are installed on the other side of the guide frame and are arranged side by side. The horizontal rollers and vertical rollers are arranged perpendicularly and form a grid-shaped window. The traction steel wire rope passes through the grid-shaped window.

[0022] Compared with existing technologies, the advantages of this utility model are as follows: In this utility model, a diesel generator installed in the middle of the hull supplies power to the traction winch and hoisting winch fixed on the hull, and the barge's movement is controlled manually from the control room. The traction wire rope led out by the traction winch passes through the guide frame installed at the end of the hull, and the other end of the traction wire rope is anchored to the anchoring pier installed on the bank. By operating the four traction winches on the hull, the barge can move from the left bank to the right bank or from the right bank to the left bank. Because there is no propeller, the draft requirement is low, so it can pass normally even when the river water level is shallow, and the operation is smooth, allowing for relatively accurate control of the hull's movement.

[0027] The present invention will be further described in detail below through embodiments. The embodiments are only used to illustrate the present invention and do not limit the scope of the present invention.

[0028] An electric towing large barge includes a riverbank A, a riverbank B, an anchoring assembly, and a hull 1. A river channel C is formed between riverbanks A and B. The anchoring assembly is vertically fixed to riverbanks A and B, close to their edges. The anchoring assembly is connected to the hull 1 via steel wire ropes. The anchoring assembly has four anchor blocks, each connected to a towing steel wire rope 5. The anchoring assembly is connected to the hull 1 via the towing steel wire rope 5, which moves the hull 1 within the river channel C.

The towing steel wire rope passes through a guide frame 6 at the end of the hull 1, and the tail end of the towing steel wire rope 5 is anchored to the anchor blocks on the riverbank.

[0029] The anchoring assembly includes anchor block 141, which is fixed at point A on the riverbank.

[0030] Anchor pier 2 142 is fixed at point A on the riverbank, and anchor pier 2 142 is located on one side of anchor pier 1 141;

[0031] Anchor pier 3143 is fixed at point B on the riverbank.

[0032] Anchor pier 4144 is fixed at point B on the riverbank. Anchor pier 4144 is located on one side of anchor pier 3143.

[0033] The straight line 1a containing anchor pier 141 and anchor pier 242 is parallel to the straight line 2b containing anchor pier 343 and anchor pier 444.

[0034] The straight line 3c containing anchor pier 141 and anchor pier 343 is parallel to the straight line d containing anchor pier 242 and anchor pier 444.

[0035] The traction wire rope 5 includes:

[0036] One end of the wire rope 51 is fixedly connected to the anchor block 141, and the other end of the wire rope 51 is connected to the winch 41 on the hull 1.

[0037] One end of the steel wire rope 252 is fixedly connected to the anchor block 3143, and the other end of the steel wire rope 252 is connected to the winch 242 on the hull 1.

[0038] One end of the steel wire rope 353 is fixedly connected to the anchor block 4144, and the other end of the steel wire rope 353 is connected to the winch 343 on the hull 1.

[0039] One end of the wire rope 454 is fixedly connected to the anchor block 2142, and the other end of the wire rope 454 is connected to the winch 444 on the hull 1.

[0040] A bankside ramp road 151 is set up in the area between steel wire rope 151 and steel wire rope 454, and the bankside ramp road 151 is close to the riverbank A.

[0041] A bankside ramp road 2152 is set up in the area between steel wire rope 252 and steel wire rope 353, and the bankside ramp road 2152 is close to the riverbank B.

[0042] The hull 1 has ramps 2 at both ends, which are hinged to the hull 1. The ramps 2 have a landing plate 3 at the front end, which is hinged to the landing plate 3.

[0043] A traction winch is installed on the hull 1. The traction winch includes a winch 41, which is fixed to one corner of one side of the hull 1. A steel wire rope 51 is connected to the winch 41.

[0044] Winch 2 42 is fixed to the other corner of one side of the hull 1, and wire rope 2 52 is connected to winch 2 42;

[0045] Winch 343 is fixed to one corner of the other side of the hull 1, and wire rope 353 is connected to winch 343;

[0046] Winch 44 is fixed to the other corner of the other side of the hull 1, and wire rope 454 is connected to winch 44.

[0047] The guide frame 6 consists of a main frame 601, vertical rollers 602, and horizontal rollers 603. The main frame 601 is fixed to the hull 1. Two vertical rollers 602 are arranged side by side on one side inside the guide frame 6. Two horizontal rollers 603 are arranged side by side on the other side inside the guide frame 6. The horizontal rollers 603 and the vertical rollers 602 are arranged perpendicularly to each other, forming a grid-shaped window. The traction wire rope 5 passes through the grid-shaped window. Because the traction wire rope 5 will have a certain displacement deviation during winding or extension, the grid-shaped window can limit the movement of the traction wire rope 5 in all directions within the grid-shaped window. On the other hand, the grid-shaped window can limit the movement of the hull 1 and ensure its stability.

[0048] A hoisting winch 7 is arranged at each of the four corners of both ends of the hull 1. A fixed bracket 8 is fixed at the front end of the hoisting winch 7. A fixed pulley 9 is set on the top of the bracket 8. A movable pulley 10 is set in the middle of both sides of the gangway 2. A hoisting wire rope 11 is pulled out from the hoisting winch 7. The hoisting wire rope 11 connects the fixed pulley 9 and the movable pulley 10 to form a pulley group. The pulley group can lift the gangway 2 more efficiently. By pulling the hoisting wire rope 11 through the hoisting winch 7, the gangway 2 can be rotated up and down.

[0049] A 12 diesel generator is installed on one side of the middle of the hull 1. The electricity generated by the 12 diesel generators drives the traction winch for operation. A 13 control room is installed on the other side.

[0050] Workflow of this solution:

[0051] When hull 1 needs to move towards the bank on one side of the river (opposite to the direction of water flow D in river channel C), the diesel generator 12 is manually operated in the control room 13 to supply power to the traction winches. The two traction winches in the direction of hull 1's movement wind up wire ropes 2 52 and 3 53. The ends of wire ropes 2 52 and 3 53 are fixed to the corresponding anchoring piers on the bank. Therefore, wire ropes 2 52 and 3 53 generate traction force during the winding process, thereby pulling hull 1 forward. At the same time, wire ropes 1 51 and 4 54 generate a release action (appropriate tension) to cooperate with the winding action of wire ropes 2 52 and 3 53, so that hull 1 moves stably with the cooperation of the front and rear (bow) wire ropes. The guide frame 6 set at the end of hull 1 generates a restraining force on the traction wire ropes 5 to control the direction of hull 1's movement more accurately and avoid large-scale displacement of hull 1.

[0052] To reduce resistance, the vessel's direction of travel is controlled at a 30° angle to the river's centerline. As the vessel approaches the bank, the hoisting winch 7 on the bank side releases the hoisting cable 11. Under the action of the fixed pulley 9 and the movable pulley 10, the gangplank 2 is slowly lowered until the ramp 3 at its front end smoothly rests on the sloping road on the bank. Vehicles on the bank travel across the ramp 3 and gangplank 2 onto the deck of the vessel. The hoisting winch 7 then winds up the hoisting cable 11, and the gangplank 2 slowly rises. Similarly, the vessel can then travel to the opposite bank (in the same direction as the water flow D in river channel C) under the action of the traction winch and traction cable 5 on the other side.
