Embodiment 1

[0026] The stopper in the present invention is used to dock the low-temperature tanker arm 99 on the low-temperature liquid tanker. The outlet of the low-temperature tanker arm 99 is provided with a flange 101, and the flange 101 is provided with a first opening bolt groove. according to figure 1 As shown, it includes a main board 1 and a sub-board 2 that are stacked and connected to each other in a plane; and a first flange limit bolt 3 is also included.

[0027] Wherein, a cavity capable of accommodating the flange 101 is formed between the middle protrusion of the sub-board 2 and the main board 1, and a U-shaped notch is formed on the sub-board 2 to accommodate the entry and placement of the loading and unloading arm 99 of the low-temperature tanker.

[0028] The first flange limit bolt 3 includes bolt cylinders and pin shafts that are vertically intersected and connected. The main board 1 is provided with a second open bolt groove that can accommodate the bolt cylinders to...

Embodiment 2

[0035] In order to perform air tightness detection after the low-temperature tanker loading and unloading arm 99 is connected, this embodiment is an improvement on the basis of Embodiment 1, and also includes a valve group connector (not shown in the figure), the valve group connector has The first outlet, the second outlet and the third outlet, the first, second and third outlets are sequentially connected with a pressure gauge 8, a safety valve 9 and an exhaust valve 10, an air source hole 11 is opened on the main board 1, and the air source The hole 11 corresponds to the center of the flange 101, and the air source hole 11 connector is installed on the air source hole 11, and the air source hole 11 connector is connected to the valve group connector through a gas pipe.

[0036]When carrying out seal detection, open the nitrogen inlet valve on the low-temperature tanker loading arm 99, fill nitrogen into the low-temperature tanker loading arm 99, the pressure gauge 8 shows th...

Embodiment 3

[0039] In order that the docking device in the present invention can be compatible with left-handed and right-handed low-temperature tanker loading and unloading arms 99, further, the main board 1 is provided with an installation reserved hole 12 for installing the valve group connector, and the installation reserved hole 12 With sealing cap. The middle part of the main board 1 is a step-shaped protrusion, and the two sides of the main board 1 are respectively provided with bolt installation holes. The first opening bolt groove is arranged at the edge of the stepped protrusion. Install the reserved hole 12, the installed reserved hole 12 is provided with a sealing cap, the valve group connector can be connected to the installation reserved hole after the sealing cap is removed, the sub-board 2 and the main board 1 are connected by bolts, The sub-board 2 can be connected to the main board 1 again after being turned 180 degrees.

Abstract

The invention relates to a stopping machine special for a low-temperature tanker loading and unloading arm. The stopping machine comprises a main plate and an auxiliary plate which are connected with each other in a plane-stacking manner. A cavity capable of containing a flange is formed between a middle protrusion of the auxiliary plate and the main plate, a U-shaped notch allowing the low-temperature tanker loading and unloading arm to enter and to be placed is formed on the auxiliary plate, and the stopping machine further comprises a first flange limiting bolt. The stopping machine is mounted on a tanker loading platform or other utensils provided with loading and unloading arms; after loading and unloading is completed and when the loading and unloading arm is contained, the loading and unloading arm is rotated and the flange at an opening of the loading and unloading arm is pushed or inserted into a space between the main plate and the auxiliary plate, the flange limiting bolt is overturned to fall into an opening bolt groove of the flange, and a butterfly-shaped nut on the flange limiting bolt is screwed to form pressure limiting. A flaring is arranged at an opening of the U-shaped notch on the auxiliary plate, so that the auxiliary plate has a guiding function, and convenience is brought to pushing-into or inserting-into of the loading and unloading arm. In addition, a sealing pad is arranged on the main plate, so that sealing can be quickly realized when the loading and unloading arm stops in place.

Description

technical field [0001] The invention relates to a loading and unloading device on a low-temperature land fluid transport vehicle, in particular to a stopper for a loading and unloading arm on a low-temperature tank vehicle. Background technique [0002] At present, at home and abroad, tankers transporting ultra-low temperature liquids below -160°C (liquefied natural gas, liquid nitrogen, liquid oxygen and other media) are equipped with low-temperature tanker loading and unloading arms. Reliably bolted to the fixed point to prevent the loading and unloading arm of the low-temperature tanker from swinging and hitting the surrounding equipment under the action of wind or other external forces in a non-working state and causing damage to the loading and unloading arm of the low-temperature tanker and surrounding equipment, and at the same time The outlet flange is required to be sealed to prevent moisture in the air from entering the outlet, freezing on the sealing surface of th...
