Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical oil transportation equipment, in particular to an oil transportation arm ship connecting short-circuit device. Background Art

[0002] The oil transfer arm is generally used to transfer the oil from the tanker to the mechanical equipment at the dock. During use, the onshore operator adjusts the position of the oil pipe joint at the end of the oil transfer arm through the operation button on the console in the operation room or the outdoor remote control to dock with the oil pipe joint on the tanker. In the fields of oil fields, refineries, pipeline transportation, etc., the oil transfer arm short-circuit device can be used to connect the oil pipeline to realize the transportation and transfer of oil products. In ports and docks, the oil transfer arm short-circuit device is used to connect the oil pipeline on the ship and the shore to realize the loading and unloading of oil products. With the continuous increase in the refining volume of domestic petrochemical refineries in recent years, With the growth of oil and refined oil, the seaborne volume has also continued to rise, and the requirements for the throughput capacity of oil terminals have become higher and higher. The efficiency and safety of traditional oil hoses can no longer meet the loading and unloading needs. Therefore, the oil transfer arm has become the most important loading and unloading tool for ports and terminals to load and unload oil, liquefied gas and other chemical products. The existing oil transfer arm structure is mostly a complete set of folding arm type pipeline system and its supporting structure. The base of this type of oil transfer arm is fixedly installed on the ground, and the upper turntable device cannot be moved as needed. It is not flexible to use and is not suitable for occasions that need to be moved, which brings inconvenience to transportation and loading.

[0003] The existing technology has the following problems:

[0004] Over-tightening of flange bolts may make disassembly difficult, making it inconvenient to disassemble during maintenance. If used for a long time or exposed to harsh environments, the flange connection may rust or accumulate dirt, increasing the difficulty of disassembly, resulting in other problems such as too many bolts, tightness, and rust, making it difficult to disassemble the oil transfer arm. Utility Model Content

[0005] The utility model aims to provide a short-circuit device for connecting an oil loading arm to a ship, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] An oil transfer arm ship short-circuit device comprises a fixed base and a column, wherein a lower flange is arranged on the top of the fixed base, and a flange mounting plate is arranged on the top of the lower flange.

[0013] By adopting the above technical solution, the right fixing block, the nut and the right fixing shell are used together. The nut can be sleeved on the outer wall of the bolt after it is fixed, so that the left and right fixing shells are connected to play a fixing role.

[0014] A further improvement of the technical solution of the utility model is that a flange fixing plate is fixedly connected to the inner wall of the left fixed shell, the outer wall of the flange fixing plate is movably connected to the inner wall of the flange mounting plate, and the bottom of the flange mounting plate passes through the upper flange plate and is welded to the top of the lower flange plate.

[0015] The above technical solution is adopted, in which a flange fixing plate, a flange mounting plate, an upper flange plate and a lower flange plate are used in combination, and the flange fixing plate is respectively fixed to the inner walls of the left fixed shell and the right fixed shell. When the two are connected, the flange mounting plate will pass through the inner wall of the flange mounting plate, thereby fixing the lower flange plate and the upper flange plate together.

[0016] A further improvement of the technical solution of the utility model is that the top of the upper flange is welded to the bottom of the column, one side of the column is fixedly connected to a connecting plate, and one side of the connecting plate is movably connected to an inner arm.

[0017] The above technical solution is adopted, in which a column, a connecting plate and an inner arm are used in combination. A connecting plate is installed on one side of the top of the column for connecting with the inner arm to support and fix the inner arm.

[0018] A further improvement of the technical solution of the utility model is that: one end of the inner arm is fixedly connected to a first bearing, the front side of the first bearing is fixedly connected to a fixed wheel, and the outer wall of the fixed wheel is sheathed with a steel rope.

[0019] The above technical solution is adopted, in which the first bearing, the fixed wheel and the steel rope are used in combination. A fixed wheel is installed on one side of the first bearing to facilitate the steel rope to drive the second bearing to rotate. In this process, the second left side can drive the outer arm to swing.

[0020] A further improvement of the technical solution of the utility model is that: the front side of the fixed wheel is fixedly connected with a second bearing, and the front side of the second bearing is movably connected with an outer arm.

[0021] The above technical solution is adopted, in which the second bearing and the outer wall are used in combination, and the outer wall can drive the outer arm to swing through the drive of the second bearing, so as to facilitate the adjustment of the angle of the outer arm for docking with the oil transportation equipment.

[0022] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0023] 1. The utility model provides an oil delivery arm ship short-circuit device, which is used in conjunction with a left fixed shell, a right fixed shell, bolts, a flange fixing plate and a flange mounting plate. The inner walls of the left fixed shell and the right fixed shell are both installed with flange fixing plates. The top of the lower flange plate is fixed with the right flange mounting plate. When the left fixed shell and the right fixed shell are connected, the flange fixing plate will pass through the inner wall of the flange mounting plate, which can fix the lower flange plate and the upper flange plate together and play the role of fixing the column at the same time. When disassembly is required, only the nuts on both sides need to be removed, and then the left fixed shell and the right fixed shell can be separated, thereby solving the problem of inconvenient flange disassembly.

[0024] 2. The utility model provides an oil transfer arm ship short-circuiting device, which is used in conjunction with a column, a connecting plate, a steel rope, a second bearing, a fixed wheel and an outer arm. The column supports the inner arm through the connecting plate. When the steel rope drives the fixed wheel to rotate, the second bearing drives the outer arm to swing, which plays a regulating role and is convenient for docking with the oil transfer equipment.
