Introduction to the structural composition of Shanghai Guanzhuo oil transfer arm

Oil arm foundation column: The vertical structural member or process pipeline that supports the oil arm. The oil arm can be installed on the dock foundation through the bolt holes on the bottom plate at the lower end of the column. The size of the column and the bottom plate is determined by the total weight of the oil arm when fully loaded and the force factors at the maximum wind pressure.     Inner arm: The     medium conveying pipeline and other structural parts between the upper rope sheave and the slewing bearing of the oil arm. Outer arm: The medium conveying pipeline and other structural parts located between the upper rope sheave and the three-dimensional joint component.     Rotary joint: Guanzhuo's single-tube oil arm contains 6 rotary joints to meet the required degrees of freedom during movement.     Seal: According to the physical and chemical properties of the transmitted product, choose from Guanzhuo's specially designed sealing materials to ensure the sealing performance of the rotary joint.     Slewing bearing: Located at the top of the column, it provides horizontal rotation movement of the oil arm.     Swivel box: The general term for the slewing bearing and medium conveying elbow located at the top of the column, which facilitates the flexible rotation of the oil arm.     Support beam: It supports the process pipeline and is a closed structural member designed according to the principle of equal strength beam. It greatly improves the rigidity of the oil delivery arm and improves the stress condition of the medium pipeline and the rotary joint.     Balance system: It consists of a counterweight and a sheave system. The main counterweight is installed on the lower full-width sheave, and the adjustable auxiliary counterweight is installed on the counterweight beam. It is adjusted by the steel cable connected to the upper empty-width sheave to balance the outer arm. The main counterweight full-width sheave is installed on the extension arm of the inner arm, leaving an appropriate distance from the shaft box to balance the entire oil delivery arm. Sheave     system: It consists of an upper sheave, a lower sheave and a wire rope to realize the transmission of the balanced load between the inner and outer arms and the counterweight.     Three-dimensional joint component: It is located at the end of the outer arm and consists of three rotary joints and elbows to adapt to the bumps, swaying and roll of the tanker. The quick connector installed on the three-dimensional joint ship flange can realize the rapid docking with the tank ship flange. The insulating flange is installed in a vertical position to prevent the generation of drift current and isolate the hull from the shore.     Interface flange: flange of the oil transfer arm that is connected to the oil collecting pipe of the tanker or to the plug.     Manual quick connector QC/DC: a mechanism that clamps the interface flange on the oil collecting pipe of the tanker without bolts.     Maintenance platform: convenient for maintenance and repair of equipment.     Safety ladder: a maintenance platform that leads all the way to the upper rope pulley.     Adjustable legs: adjustable support mechanism installed on the three-dimensional joint assembly, which can effectively improve the stress condition of the manifold flange of the tank ship.     The three-dimensional joint and column discharge interface facilitate the discharge of residual liquid in the pipe.     Reset locking device: fix the inner and outer arms after reset.     The above is the oil transfer arm (gas transfer arm, LNG cryogenic medium gas transfer arm) produced by Shanghai Guanzhuo Enterprise Development Co., Ltd.     Shanghai Guanzhuo Company is a high-quality supplier of PetroChina, Sinopec, and CNOOC. It mainly designs and produces various supporting equipment for docks and storage areas: mainly cable release hooks, oil transfer arms, LNG cryogenic gas transfer arms, boarding ladders, crane pipes, oil tank drainage systems, etc. The products are exported overseas.
