Description

Technical Field

[0001] The present invention relates to the technical field of valve body transportation, in particular to an intelligent suspension and transportation system for large-scale marine valve bodies. Background Art

[0002] The Marine Large Valve Body Suspension and Conveying Device is a device designed specifically for transporting and installing large equipment or components such as valve bodies on board ships. Its function is to safely and stably convey these heavy components by suspending them, ensuring they are not damaged during transport and can be efficiently moved to the designated location for installation or maintenance.

[0003] At present, in the process of transporting large valve bodies on board ships, the valve bodies are suspended by using ropes and hooks on the suspension frame, and then the suspension frame is transported through the conveying track to complete the transportation of the valve bodies. However, in the process of transporting large valve bodies on board ships, the ups and downs of the waves when the ship is sailing on the sea will cause the ship to shake up and down or left and right. The shaking of the ship will eventually cause the suspended valve body to shake, and in severe cases, it will fall off. Summary of the Invention

[0018] The present invention provides an intelligent suspension and conveying system for large marine valve bodies. Compared with the existing technology, it has the following advantages:

[0019] 1. In this invention, when the valve body suspended on the hook shakes with the hull, the driving motor drives the driving disc on the output shaft to rotate. The driving disc cooperates with the driving arc rod through the driving arc groove, causing the four L-shaped translation blocks on the cross plate to move outward synchronously. The anti-sway holes on the L-shaped fixed plate are used to tighten the suspension rope, so that the valve body on the hook is in a stable state, ensuring that the valve body will not fall off due to excessive shaking during transportation.

[0020] 2. The present invention drives the adjustment block through the electric push rod. The adjustment block slides between the positioning slide and the limit plate, so that the adjustment block pushes the suspension rope inward through the adjustment hole, making the suspension rope in the inclined state appear curved. By further tightening the suspension rope, the stability of the valve body during the conveying process is effectively improved.

[0021] 3. In the present invention, when the driving disk rotates, the driving disk will synchronously drive the adjusting screw to rotate. By utilizing the cooperation between the adjusting screw and the threaded hole on the lifting column, and the cooperation between the limiting vertical block and the limiting vertical slot, the lifting column will move vertically downward through the lifting slide bar, and the valve body will be pressed down by the pressing plate on the lifting column, thereby improving the firmness between the valve body and the hook;

[0022] 4. In the present invention, during the downward pressing process, the pressing plate will pass through the limit of the lifting plate and the reaction force of the upper limit spring on the lifting block, thereby ensuring that the pressing plate will not cause excessive pressure on the valve body during the downward pressing process. At the same time, the reaction force of the limit spring can also ensure that the pressing plate will not cause excessive tension on the suspension rope during the downward pressing process, thereby ensuring the fastening force between the hook and the valve body, and effectively enhancing the use effect of the suspension conveying device on the ship.

[0034] The suspension frame 2 is provided with an anti-sway component, which keeps the valve body hung on the hook 9 in a stable state.

[0037] In this embodiment, the adjusting block 25 is driven by the electric push rod 24, and the adjusting block 25 will slide through the limit between the positioning slide 26 and the limit plate 23, so that the adjusting block 25 uses the adjusting hole 27 to push the suspension rope 7 inward, so that the inclined suspension rope 7 is curved. By further tightening the suspension rope 7, the stability of the valve body during the transportation process is effectively improved.

[0038] A pressing assembly is provided at the bottom of the suspension bracket 2, and the firmness between the hook 9 and the valve body is improved by the pressing assembly. The pressing assembly includes an adjusting screw 28 fixedly mounted on the driving disk 13, a horizontal plate 29 fixedly mounted on the connecting plate 20, a lifting slide hole 30 is provided on the horizontal plate 29, a lifting column 31 is slidably mounted in the lifting slide hole 30, a threaded hole 32 is provided at the top of the lifting column 31, a mounting cylinder 33 is fixedly mounted on the bottom end of the lifting column 31, a limited vertical block 34 is fixedly mounted on the side end surface of the lifting column 31, a limited vertical groove 35 is provided on the inner side surface of the lifting slide hole 30, a lifting groove 36 is provided inside the mounting cylinder 33, and a lifting block 31 is slidably mounted inside the lifting groove 36. 7.

[0039] When the lever 31 is in the unlocked position, the lever 31 is in the unlocked position, and the locking cam 39 is in the unlocked position, so that the lever 31 is in the unlocked position and the locking cam 39 is in the unlocked position.

[0040] Working principle:

[0041] During use, when the valve body suspended on the hook 9 shakes with the hull, the driving motor 11 drives the driving disc 13 on the output shaft 12 to rotate, and the driving disc 13 cooperates with the driving arc rod 19 through the driving arc groove 14, so that the four L-shaped translation blocks 18 on the cross plate 6 move outward synchronously, and the anti-sway hole 22 on the L-shaped fixed plate 21 is used to tighten the suspension rope 7, so that the valve body on the hook 9 is in a stable state;

[0042] The electric push rod 24 drives the adjusting block 25, which slides between the positioning slide plate 26 and the limiting plate 23, so that the adjusting block 25 pushes the suspension rope 7 inward through the adjusting hole 27, so that the suspension rope 7 in the inclined state is bent, and the suspension rope 7 is further tightened;

[0043] When the driving disk 13 rotates, the driving disk 13 will synchronously drive the adjusting screw 28 to rotate. By virtue of the cooperation between the adjusting screw 28 and the threaded hole 32 on the lifting column 31, and the cooperation between the limiting vertical block 34 and the limiting vertical groove 35, the lifting column 31 will move vertically downward through the lifting slide rod, and the valve body will be pressed down by the pressing plate 39 on the lifting column 31, thereby improving the firmness between the valve body and the hook 9.

[0044] When the pressing plate 39 is pressed down, the pressing plate 39 will pass through the limit of the lifting plate and the reaction force of the limit spring 40 on the lifting block 37, thereby ensuring that the pressing plate 39 will not cause excessive pressure on the valve body during the pressing process. At the same time, the reaction force of the limit spring 40 can also ensure that the pressing plate 39 will not cause excessive tension on the suspension rope 7 during the pressing process, thereby ensuring the fastening force between the hook 9 and the valve body, and effectively enhancing the use effect of the suspension conveying device on the ship.
