It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0034] The ship side pad support device of the present invention is used to support the pad 200, and the pad 200 is arranged between the right side wall of the hull 100 and the equipment to be installed 300, such as Figures 1 to 7As shown, the ship side pad support device of the present invention includes a fixing plate 1, a first end of the fixing plate 1 is fixed to the middle part of the lower end of the hull 100, a second end of the fixing plate 1 extends downward and is hinged with a swing arm 2, and the rotation axis of the swing arm 2 is arranged along the front-rear direction; so that the swing arm 2 can swing up and down; the end of the swing arm 2 away from the fixing plate 1 extends to the right and is fixed with a fixing arm 3 extending upward, the fixing arm 3 is hinged with a clamping arm 4 extending to the left, and the rotation axis of the clamping arm 4 is arranged vertically, so that the swing arm can swing back and forth; the left end of the clamping arm 4 is located on the left side of the rotation axis of the swing arm 2; therefore, the left end of the clamping arm 4, the rotation axis of the swing arm 2 and the right end of the clamping arm 4 form a lever structure, and the rotation axis of the swing arm 2 The fulcrum of the lever structure, the part of the clamping arm 4 located on the left side of the rotation axis of the swing arm forms a stopper 41; since the rotation axis of the clamping arm 4 is arranged vertically, when the swing arm 2 swings downward, the clamping arm 4 will follow the swing arm 2 to rotate around the rotation axis of the swing arm 2, so that the stopper 41 moves upward; since the lower end of the hull 100 abuts against the upper end of the stopper 41, when the stopper 41 moves upward, the hull 100 can apply a downward reaction force to the stopper 41, thereby blocking the stopper 41 from moving upward, and further blocking the swing arm 2 from swinging downward; at least part of the fixed arm 3 protrudes from the right side wall of the hull 100, and the part of the fixed arm 3 protruding from the right side wall of the hull 100 forms The support portion is formed, and the lower end of the pad 200 abuts against the upper end of the support portion; since the stopper 41 is located on the left side of the rotation axis of the swing arm 2, it can prevent the swing arm 2 from swinging downward, and the fixed arm 3 is fixedly connected to the swing arm 2, so the stopper 41 can prevent the supporting portion from moving downward, so that the supporting portion can support the pad 200; when it is necessary to remove the pad 200 from the right side wall of the hull 100, swinging the clamping arm 4 forward or backward can move the stopper 41 from the left side of the rotation axis of the swing arm 2 to the right side of the rotation axis of the swing arm 2. At this time, the clamping arm 4 is located on the right side of the rotation axis of the swing arm 2 as a whole. Therefore, when the swing arm 2 swings downward under the action of gravity and drives the stopper 4 When the swing arm 2 rotates around the rotation axis, the stopper 41 moves downward relative to the hull 100 as a whole. At this time, the hull 100 cannot apply a reaction force to the stopper 41, thereby releasing the stopper 41 from stopping the swing of the swing arm 2, so that the swing arm 2 can drive the supporting part to move below the hull 100, vacating the space below the pad 200, avoiding the interference of the supporting part with the pad 200 when taking out the pad 200 from between the hull 100 and the equipment to be installed 300, so that the operator can smoothly take and place the pad; therefore, the ship side pad support device of the present invention can not only support the pad, but also facilitate the operator to take and place the pad from between the equipment to be installed and the hull.

[0035] Furthermore, in order to facilitate the swinging of the stopper 41 to the bottom of the hull 100, the upper end of the stopper 41 interferes with the lower end of the hull 100 during the swinging process. The side pad support device includes an adjusting bolt 5 and a first protrusion 61 fixed to the upper end of the fixed arm. The first protrusion 61 protrudes toward one side of the fixed arm 3. The threaded end of the adjusting bolt 5 passes through one end of the clamping arm 4 close to the fixed arm 3 and is screwed to the first protrusion 61. The adjusting bolt 5 forms a rotating shaft of the clamping arm 4.

[0036] Specifically, before moving the stopper 41 to the bottom of the hull 100, the adjusting bolt 5 is rotated counterclockwise to move the clamping arm 4 downward so that the clamping arm 4 and the hull 100 are spaced apart from each other. Moreover, after moving the stopper 41 to the bottom of the hull 100, the adjusting bolt 5 is rotated clockwise to move the clamping arm 4 upward so that the upper end of the stopper abuts against the lower end of the hull, thereby making the stopper 41 press against the lower end of the hull 100, thereby improving the stability of the ship side pad support device of this embodiment.

[0037] In this embodiment, the supporting part includes a push piece 7 and a second protrusion 62 fixed to the upper end of the fixed arm 3, the second protrusion 62 protrudes toward one side of the fixed arm 3, the push piece 7 is movably arranged in the second protrusion 62, and the lower end of the pad 200 abuts against the upper end of the push piece 7. By adjusting the position of the push piece 7, the fixing height of the pad 200 can be adjusted, thereby improving the convenience of use of the ship side pad support device of this embodiment.

[0038] Specifically, the push member 7 is a push bolt, and a threaded hole for the push bolt to pass through is provided in the second protrusion 62. In other embodiments of the present invention, the push member 7 is a column, and a set screw is passed through the side wall of the second protrusion 62, and the threaded end of the set screw presses against the outer peripheral side of the column to achieve locking of the push member 7 after the position is adjusted.

[0039] Specifically, Figure 3 , Figure 7 As shown, the upper end of the fixed arm 3 is fixedly connected with a support plate 6, the left side of the support plate 6 protrudes from the left side wall of the fixed arm 3 to form a second protrusion 62, and the right side of the support plate 6 protrudes from the right side wall of the fixed arm 3 to form a first protrusion 61.

[0040] In this embodiment, the clamp arm 4 is a vertically arranged plate body, and two plates are provided. The two plates are arranged at intervals in front and back, and the fixed arm 3 is located between the two plates. Thereby further improving the stability of the ship side pad support device of this embodiment. In other embodiments of the present invention, only one clamp arm 4 is provided, and the width of the clamp arm 4 in the front and back direction is set larger, thereby ensuring the stability of the ship side pad support device. Specifically, a vertically arranged round tube is welded to the right end of the plate body, and the round tube is sleeved on the outside of the adjusting bolt 5, and the end of the nut of the adjusting bolt 5 abuts against the end of the round tube.

[0041] In this embodiment, the upper end of the fixing plate 1 is welded to the lower end of the hull 100. A method for using the above-mentioned ship side pad support device comprises the following steps:

[0042] Step S1, fixing the upper end of the fixing plate 1 to the lower end of the hull 100;

[0043] Step S2, rotating the swing arm 2 so that the clamping arm 4 is in a horizontal state, and then rotating the clamping arm 4 to move the stopper 41 to the left side of the rotation axis of the swing arm 2 so that the upper end of the supporting portion abuts against the lower end of the pad 200;

[0044] Step S3, when the pad 200 needs to be repaired, rotate the clamping arm 4 and move the stopping portion 41 to the right side of the rotation axis of the swing arm 2, so that the swing arm 2 swings downward under the action of gravity, so that the supporting portion moves to the bottom of the hull 100.

[0045] Further, in step S2, before the stopper 41 is moved to the left side of the rotation axis of the swing arm 2, the adjusting bolt 5 is rotated counterclockwise to move the clamp arm 4 downward, so that the stopper 41 and the hull 100 are arranged with an interval therebetween; after the stopper 41 is moved to the left side of the rotation axis of the swing arm 2, the adjusting bolt 5 is rotated clockwise to move the clamp arm 4 upward, so that the upper end of the stopper 41 abuts against the lower end of the hull 100;

[0046] In step S3 , before rotating the clamping arm 4 , the adjusting bolt 4 is rotated counterclockwise to move the clamping arm 4 downward, so that the stopper 41 and the hull 100 are arranged with an interval therebetween.

[0047] In this embodiment, in step S2, after the stopper 41 is moved to the bottom of the hull 100, the following steps are performed: adjusting the push member 7 upward so that the upper end of the push member 7 abuts against the lower end of the pad 200;

[0048] In step S3, before rotating the clamping arm 4, the pushing piece 7 is adjusted downward so that the lower end of the pad 200 is out of contact with the pushing piece 7; after the lower end of the pad 200 is out of contact with the pushing piece 7, the pad 200 no longer applies downward pressure to the pushing piece 7, so the pressure between the stopping portion 41 and the lower end of the hull is reduced, thereby reducing the friction between the stopping portion 41 and the hull; this operation can rotate the clamping arm 4 without adjusting the adjusting bolt 5.

[0049] Furthermore, the pushing member 7 is a pushing bolt, and the upper end of the pushing bolt is brought into contact with the lower end of the pad 200 by rotating the pushing bolt.

[0050] The use process of the ship side pad support device of the present invention is as follows: first, fix the upper end of the fixing plate 1 to the lower end of the hull 100, then swing the swing arm 2 to a horizontal state so that the clamping arm 4 also remains horizontal, and then rotate the adjusting bolt 5 counterclockwise so that there is a gap between the upper end of the clamping arm 4 and the lower end of the hull 100, then rotate the clamping arm 4 to rotate the stopper 41 to the left side of the rotating shaft of the swing arm 2, and then rotate the adjusting bolt 5 clockwise so that the upper end of the stopper 41 presses against the lower end of the hull 100 to support the pad 200; when the pad 200 needs to be removed, first rotate the adjusting bolt 5 counterclockwise, and then rotate the clamping arm 4 so that the stopper 41 rotates to the right side of the rotating shaft of the swing arm 2, and then release the swing arm 2, and the swing arm 2 swings downward under the action of gravity, so that the supporting part moves to the bottom of the hull.

[0051] In summary, the ship side pad support device of the present invention can meet the free switching between the supporting and non-supporting states, not only can it support the pad 200, but also it is convenient for the operator to take and place the pad between the equipment to be installed 300 and the hull 100, so as to meet the frequent disassembly and installation of the pad 200. Moreover, the ship side pad support device of the present invention can be installed under the hull 100 for a long time, providing support force for the pad 200, preventing the pad 200 from sliding down due to the vibration of the equipment operation, and extending the service life of the equipment.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
