The working principle is as follows:

when the oil port height adjusting device is used, a ship upper section bracket is erected on the ground through a second adjusting supporting leg 9 at one end of a second bracket 6, the other end of the second bracket 6 is placed on a ship board edge rail and can be fixed by a rope or does not need to be fixed, and the height can be adjusted by adjusting the second adjusting supporting leg 9 so as to meet the height requirements of loading and unloading oil ports of different ships, so that the whole ship upper section bracket is placed below a loading and unloading oil port on the ship;

the shore base bracket is placed at a connection interface of an oil delivery hose on the shore of a wharf, the height of the first bracket 1 can be adjusted through four first adjusting support legs 5 at the bottom of the first bracket 1, and the requirements of oil loading and unloading interfaces with different heights are met;

then the bridge is arranged between the shore base bracket and the shipboard bracket, wherein a front pulley block 13 of the bridge is inserted into a first slide rail 4 at the middle part of the shore base bracket, a rear pulley block 14 is inserted into a second slide rail 8 at the upper part of the shipboard bracket, and a first pulley limit plate 15 and a second pulley limit plate 16 at two ends of the first slide rail 4 and the second slide rail 8 are respectively arranged, after the bridge is arranged, the front pulley block 13 and the rear pulley block 14 can respectively slide back and forth in the first slide rail 4 and the second slide rail 8, the first pulley limit plate 15 and the second pulley limit plate 16 can bear specific push-pull force, the rollers 23 are prevented from separating from the first slide rail 4 and the second slide rail 8, so as to prevent the bridge from separating from the shore base bracket and the shipboard bracket, a connecting plate 19 can drive the bridge to freely rotate on a first pin shaft 20 and a second pin shaft 21, thereby enabling the whole bridge to generate displacement in the horizontal direction and the vertical direction within, the extension or the shortening of the whole bridge is realized, the bridge can freely slide along the first slide rail 4 and the second slide rail 8 of the base bracket and the shipboard bracket on the shore, when the overlap joint end of the shipboard bracket and the shipboard is lifted or lowered, the sliding of the bridge along the first slide rail 4 and the second slide rail 8 is not influenced, and the complex working condition of the bridge on the water surface when the oil tanker loads and unloads is met.

After the oil conveying hose is installed, the oil conveying hose conveys oil on the first carrier roller 2, the third carrier roller 11 and the second carrier roller 7 of the onshore base bracket, the bridge and the shipboard bracket, the oil conveying hose slides along each carrier roller when extending or shortening on the first carrier roller 2, the third carrier roller 11 and the second carrier roller 7, the friction is very small, if the distance between an oil tanker and a wharf is not large, the oil conveying hose can be supported only by the onshore base bracket and the shipboard section bracket, and the suspension section distance of the oil conveying hose between the two brackets is very short, so that the oil conveying hose can be well protected without the bridge.

In the using process, the oil delivery hose is curled from the connection interface of the oil delivery hose on the quay and is always connected to an oil loading and unloading interface on a ship of the oil tanker through the first carrier roller 2, the third carrier roller 11 and the second carrier roller 7, the absolute expansion length of the winding sections of the hose on the first bracket 1, the second bracket 6 and the third bracket 10 is ensured to be more than or equal to the displacement variable of the oil delivery hose caused by the change of external environment in the loading and unloading process, namely the absolute value difference between the bending length of the oil delivery hose on the first bracket 1, the second bracket 6 and the third bracket 10 and the absolute value difference between the lengths of the first bracket 1, the second bracket 6 and the third bracket 10 are more than the displacement length of the oil delivery hose required by the sea tide amplitude, the draft depth change and the swinging amplitude of the oil tanker, when the oil tanker is loaded or the sea water falls, the part of the oil delivery hose which is bent and placed on the first bracket 1, the second bracket 6 and the third bracket 10 is straightened, when the oil tanker is unloaded or sea water rises and tides, part of the oil delivery hoses which are bent and placed on the first bracket 1, the second bracket 6 and the third bracket 10 are compressed, when the oil tanker swings and shakes, the oil delivery hoses are simultaneously straightened or compressed, the oil delivery hoses which are bent and placed on the first bracket 1, the second bracket 6 and the third bracket 10 move along with the rolling of the first carrier roller 2, the third carrier roller 11 and the second carrier roller 7, the friction is small, the oil delivery hoses are supported by the first bracket 1, the second bracket 6 and the third bracket 10 and do not need to be lifted, the suspended section is shortened, the sliding scratch and sling lifting stress of the oil delivery hoses on the ground are avoided, and the possibility of being extruded by the oil tanker is also avoided.

After the oil delivery hose is connected with the oil tanker, the oil delivery hose is folded and twisted at the span between the wharf and the oil tanker, the oil tanker shakes and pulls on the sea surface, and the oil delivery hose is subjected to the actions of torque, friction, abrasion and extrusion and has the risks of breakage and breakage.

The above embodiments are merely descriptions of the embodiments of the present invention, and do not limit the concept and scope of the present invention, and equivalent structures and direct or indirect applications of the technical solutions of the present invention by those skilled in the art should fall within the protection scope of the present invention without departing from the design solutions of the present invention.
