Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a novel tugboat trolley with adjustable width. Background Art

[0002] A tugboat trolley is a device used for transporting small ships. Its main function is to move small ships or their parts. Traditional tugboat trolleys have a fixed width and are only suitable for specific types of ships. For extra-wide small ships, they need to be re-produced and adapted, which is not conducive to large-scale production and cost reduction. In addition, due to the fixed width, traditional tugboat trolleys cannot provide sufficient support and stability when facing different widths, thus affecting the safety and efficiency of tugboat trolley operations.

[0003] The problems with conventional tugboat trolleys are as follows:

[0004] (1) The width of traditional tugboat trolleys is fixed and is only suitable for specific types of ships. For extra-wide small ships, they need to be re-produced and adapted, which is not conducive to large-scale production and cost reduction.

[0005] (2) Due to the fixed width, the traditional tugboat trolley cannot provide sufficient support and stability when facing different widths, thus affecting the safety and efficiency of the tugboat trolley operation. Summary of the invention

[0008] A novel tugboat trolley with adjustable width comprises a chassis, wherein the chassis comprises two longitudinal beams; the chassis further comprises a plurality of retractable cross beams, wherein the two ends of the cross beams are respectively fixed to the two longitudinal beams; the cross beams comprise an outer tube and an inner rod, wherein the inner rod is passed through the outer tube; a gap is provided between the inner rod and the outer tube so as to allow the inner rod to move inside the outer tube; the outer tube and the inner rod are connected by a locking component; a plurality of ship fixing columns are provided on the chassis; movable pads are hinged on the tops of the ship fixing columns.

[0009] Furthermore, the locking component is a locking bolt.

[0010] Furthermore, the locking bolts are inserted into the outer tube and the inner rod.

[0011] Furthermore, the outer tube and the inner rod are both provided with a plurality of locking interfaces for accommodating locking bolts.

[0012] Furthermore, ship fixing columns are provided on both longitudinal beams.

[0013] Furthermore, each crossbeam is provided with a ship fixing column.

[0014] Furthermore, the two longitudinal beams are parallel to each other, and the transverse beams are parallel to each other.

[0015] Furthermore, the movable pad is connected to the ship-fixing column through an articulated bolt; the articulated bolt is simultaneously passed through the movable pad and the ship-fixing column.

[0016] Furthermore, the top of the movable cushion block is higher than the top of the ship fixing column.

[0017] Furthermore, the novel tugboat trolley with adjustable width also includes wheels, which are connected to the bottom of the longitudinal beam.

[0018] The beneficial effects of the present invention are as follows: the tugboat trolley of the present invention can adjust the width of the tugboat trolley according to the width of the small ship, and can carry small ships of different widths. The tugboat trolley of the present invention can be autonomously adapted to different ship bottoms by setting movable pads, ensuring sufficient support and stability, thereby improving the safety and efficiency of the tugboat trolley operation.

[0024] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, a novel width-adjustable tugboat trolley includes a chassis 10, which includes two longitudinal beams 20; the chassis 10 also includes a plurality of retractable cross beams 30, and the two ends of the cross beams are respectively fixed to the two longitudinal beams. The two longitudinal beams are parallel to each other, and the cross beams are parallel to each other.

[0026] The cross beam 30 includes an outer tube 31 and an inner rod 32, and the inner rod 32 is disposed through the outer tube 31. A gap is provided between the inner rod 32 and the outer tube 31 so that the inner rod can move in the outer tube.

[0027] The outer tube 31 and the inner rod 32 are connected via a locking component, which is a locking bolt 33 .

[0028] The locking bolt 33 is inserted into the outer tube 31 and the inner rod 32 .

[0029] A plurality of locking interfaces for accommodating locking bolts are provided on the outer tube 31 and the inner rod 32. Since the positions of the locking interfaces coincide with the positions of the locking bolts, the locking interfaces are not shown in the figure.

[0030] A plurality of ship-fixing columns 40 are provided on the chassis 10. Along the width direction of the chassis, the heights of the ship-fixing columns gradually decrease from both sides to the middle.

[0031] There are ship-fixing columns on both longitudinal beams and ship-fixing columns on each transverse beam.

[0032] A movable cushion block 41 is hinged on the top of the ship fixing column 40 .

[0033] The movable cushion block 41 is connected to the ship-fixing column 40 via an articulated bolt 42 ; the articulated bolt 42 is simultaneously passed through the movable cushion block 41 and the ship-fixing column 40 .

[0034] The top of the movable cushion block 41 is higher than the top of the ship fixing column 40 .

[0035] The novel tugboat trolley with adjustable width further comprises wheels 11 , which are arranged at the bottom of the longitudinal beam 20 .

[0036] The tugboat trolley of the present invention has a chassis composed of a longitudinal beam and a retractable cross beam; the cross beam is retracted and extended by moving an inner rod in an outer tube, and the inner rod and the outer tube are fixed by locking bolts, thereby realizing step-by-step adjustment of the width of the tugboat trolley.

[0037] When in use, the small vessel 50 is placed on the movable pad. The tugboat trolley of the present invention can adjust the width of the tugboat trolley according to the width of the small vessel by extending and retracting the crossbeam, and can load small vessels of different widths. Figure 3 As shown, after adjusting the width, the tugboat can load a small ship with a width D1 of 3 meters; Figure 4 As shown, after adjusting the width, the tugboat can load a small ship with a width D2 of 3.6 meters; Figure 5 As shown, after adjusting the width, the tugboat trolley can load a small vessel with a width D3 of 4 meters.

[0038] The tugboat trolley of the present invention innovates the ship fixing column, a movable pad is hinged to the top of the ship fixing column, a hinge bolt serves as the rotation center of the movable pad, and the top of the movable pad is higher than the top of the ship fixing column, so that the movable pad can be autonomously adapted according to different ship bottoms, ensuring sufficient support and stability, thereby improving the safety and efficiency of the tugboat trolley operation.

[0039] The tugboat trolley of the present invention can adjust the width of the tugboat trolley according to the width of the small ship, and can carry small ships of different widths. The tugboat trolley of the present invention can be autonomously adapted to different ship bottoms by providing movable pads, ensuring sufficient support and stability, thereby improving the safety and efficiency of the tugboat trolley operation.

[0040] The tugboat trolley of the present invention has a simple, safe and reliable installation and operation process.
