Description

Technical Field

[0001] This application relates to the field of oil delivery arm technology, and more particularly to oil delivery arms. Background Art

[0002] A marine oil loading arm, also known as a marine liquid loading arm, is a piece of equipment installed on a dock to complete the loading and unloading of liquid petrochemical products. It is capable of adapting to different tides, freeboard, and ship movements, and is a highly efficient and safe oil terminal loading and unloading equipment.

[0003] Oil transfer arms are widely used in marine liquid loading and unloading. However, current oil transfer arms are difficult to adjust in terms of oil transfer height and position. At high sea levels, the oil transfer range of oil transfer arms is obviously insufficient for larger ships, requiring the connection of external oil transfer pipelines, which increases the ship's time in port and reduces oil transfer efficiency. Therefore, to solve the above problems, we have provided oil transfer arms. Utility Model Content

Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-4 This utility model provides a technical solution for an oil conveying arm:

[0023] The oil delivery arm includes a support cylinder 1, a fixed base 2 above the support cylinder 1, a first hydraulic push rod 3 fixedly installed on the inner bottom wall of the support cylinder 1, a lifting column 4 fixedly connected to the inner ring of the support cylinder 1, the telescopic end of the first hydraulic push rod 3 fixedly connected to the bottom end of the lifting column 4, a connecting oil pipe 5 fixedly connected to the inner ring of the fixed base 2, a telescopic hose 7 fixedly connected to the right end of the connecting oil pipe 5, a drain pipe 9 fixedly connected to the right end of the telescopic hose 7, an outer sliding cylinder 8 fixedly connected to the outer surface of the drain pipe 9, a fixed cylinder 6 fixedly connected to the outer surface of the connecting oil pipe 5, the outer surface of the fixed cylinder 6 slidingly connected to the inner ring of the outer sliding cylinder 8, two fixed blocks 11 fixedly connected to the outer surface of the fixed base 2, a second hydraulic push rod 12 fixedly installed on the right side of each of the two fixed blocks 11, and the telescopic ends of the two second hydraulic push rods 12 fixedly connected to... The connecting blocks 13, with their adjacent sides fixedly connected to the outer surface of the outer slide cylinder 8, are connected to each other. The hydraulic push rod is powered by an electric motor and outputs pressurized oil through a bidirectional gear pump. The oil is controlled by the oil circuit integration block and sent to the oil cylinder to realize the reciprocating motion of the piston rod. The hydraulic push rod is suitable for applications requiring push-pull linear motion, as well as applications requiring lifting, lowering, or clamping of workpieces. It can also be used for centralized or programmed control of workpieces in remote high-altitude and dangerous areas. It has been widely used in metallurgy, mining, coal, power, machinery, grain, cement, chemical, water conservancy, transportation and other sectors, and is a general-purpose power source. Specifically, through the first hydraulic push rod 3, and in cooperation with the lifting column 4 and the fixed seat 2, the connecting oil pipe 5, the fixed cylinder 6 and the oil drain pipe 9 can be driven to adjust the height, thereby achieving the effect of adjusting the oil delivery height.

[0024] In this embodiment, a strip-shaped hole 15 is provided on the outer surface of the support cylinder 1, and a reinforcing plate 16 is fixedly connected to the outer surface of the lifting column 4. The upper surface of the reinforcing plate 16 is fixedly connected to the outer surface of the fixed cylinder 6. The left end of the connecting oil pipe 5 is fixedly connected to the oil extraction pipe 10, and the left end of the oil extraction pipe 10 is fixedly connected to the first connecting plate 23. The bottom end of the drain pipe 9 is fixedly connected to the second connecting plate 14. Specifically, by setting the strip-shaped hole 15 and the reinforcing plate 16, the support for the fixed cylinder 6 is deepened, which will make the fixed cylinder 6 more solid. The first connecting plate 23 and the second connecting plate 14 can be used to connect to the oil delivery component more flexibly.

[0025] In this embodiment, a limiting slide block 20 is fixedly connected to the outer surface of the support cylinder 1. A sliding plate 21 is slidably connected to the inner wall of the limiting slide block 20. A limiting block 22 is fixedly connected to the left side of the sliding plate 21. The left side of the limiting block 22 is fixedly connected to the outer surface of the oil extraction pipe 10. An mounting plate 18 is fixedly installed at the bottom end of the support cylinder 1. Two sets of mounting holes 19 are opened on the upper surface of the mounting plate 18. Two reinforcing blocks 17 are fixedly connected to the upper surface of the mounting plate 18. The sides of the two reinforcing blocks 17 that are close to each other are fixedly connected to the outer surface of the support cylinder 1. Specifically, through the cooperation of the limiting slide block 20, the sliding plate 21 and the limiting block 22, the height of the fixed cylinder 6 and the oil extraction pipe 10 can be adjusted more stably to avoid shaking. Through the cooperation of the mounting plate 18 and the mounting holes 19, the oil delivery arm can be stably supported to ensure the stability during oil delivery.

[0026] Working principle: First, the support cylinder 1 is installed through the mounting plate 18 and mounting hole 19. Then, the device is connected to the power supply. When the oil delivery height is adjusted, the first hydraulic push rod 3 is activated to extend and retract, which will drive the fixed seat 2, the connecting oil pipe 5, and the fixed cylinder 6 to move up and down through the lifting column 4. At the same time, the oil discharge pipe 9 will also be adjusted in height. Then, the two second hydraulic push rods 12 are activated to extend, which can drive the outer sliding cylinder 8 to move outward through the connecting block 13, and will cause the telescopic hose 7 to unfold, thereby increasing the oil delivery distance of the oil discharge pipe 9 and enabling oil delivery over a wider range.

[0027] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
