Problems solved by technology
After the tanker has been used for many years, the tank mouth has problems such as unevenness and deformation. The existing sealing cap cannot seal the sealing cap well, especially when the tank mouth has a certain inclination angle, the sealing effect is even worse, and it is easy to cause liquid volatilization, affecting loading and unloading efficiency

A sealing vertical tube for a loading arm comprises a fixed outer tube and a telescopic inner tube. The fixed outer tube is sleeved with a sealing cap lifting tube, and a sealing cap matched with a tank opening of a tank car is installed at the lower end of the sealing cap lifting tube. The sealing cap is provided with a sealing cap panel, a guide pipe of the sealing cap panel is arranged under the sealing cap panel, and the guide pipe and the sealing cap lifting tube are coaxially arranged. A retention ring matched with the lower end of the guide pipe is disposed at the lower end of the telescopic inner tube. The lower surface of the sealing cap panel is provided with acircle ofinflation type sealing mechanism closely matched with the tank opening. A clamping mechanism is arranged on the portion, between the inflation type sealing mechanism and the guide pipe, of the sealing cap panel and is matched with the inner wall of the tank opening so that the sealing cap panel can be closely attached to the tank opening. By means of the clamping mechanism and the inflation type sealing mechanism, it can be guaranteed that gas in the tank opening does not leak outwards, the inclination angle caused after the tank opening is used for many years and becomes uneven or oval can also be complemented, and good connection between the tank opening and the sealing cap is achieved.
Description
technical field [0001] The invention relates to a truck loading crane pipe, in particular to a sealing drop pipe for a truck loading crane pipe. Background technique [0002] When loading and unloading volatile liquids such as gasoline, the vertical pipe of the crane pipe is extended to the bottom of the tank by telescopic means. The lower end of the vertical pipe is provided with a conical sealing cap. After finishing, the drop pipe can also be pulled out from the tanker. After the tanker has been used for many years, the tank mouth has problems such as unevenness and deformation. The existing sealing cap cannot seal the sealing cap well, especially when the tank mouth has a certain inclination angle, the sealing effect is even worse, and it is easy to cause liquid The volatilization will affect the loading and unloading efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a reasonable-designed and conv...
