Positioning device of glass fiber reinforced plastic ring for LNG tank for ore vehicle and positioning method

Abstract

The invention belongs to machining devices and methods for an LNG tank for an ore vehicle, aims to solve the technical problem that a glass fiber reinforced plastic ring used for supporting inner andouter tank bodies of the LNG tank are not easy to position during installation, and provides a positioning device of the glass fiber reinforced plastic ring of the LNG tank for the ore vehicle and a positioning method. A limiting ring of the positioning device is coaxially fixed on the lower surface of a cover plate; the center of the cover plate is sleeved with a positioning rod, and the positioning rod is fixedly connected with the cover plate through a fastening sleeve. Four rulers are arranged on the upper surface of the cover plate, the rulers face the same direction, the distances between the ends, facing the inner side, of the rulers and the geometric center of the cover plate are equal, the included angle between every two adjacent rulers is 90 degrees, and a notch is formed in thecover plate and located in any side, facing the end of the outer side, of each ruler. The positioning method comprises the steps that the positioning rod is inserted into the glass fiber reinforced plastic ring, the cover plate is arranged on the upper surface of an outer tank body seal head, the limiting ring is located in a straight edge section of the outer tank body seal head, and the four rulers are identical in reading by adjusting the position of the cover plate, namely the glass fiber reinforced plastic ring is located in the center of the outer tank body seal head.

Description

technical field [0001] The invention belongs to an LNG tank processing device and method for an ore vehicle, and in particular relates to a positioning device and a positioning method for a glass steel ring of an LNG tank for an ore vehicle. Background technique [0002] The liquefied natural gas tank for heavyweight ore trucks provides liquefied natural gas fuel for ore trucks. The tank body is divided into inner and outer layers, the middle part of the tank body is columnar, and the two ends are arc-shaped, and the two ends are the upper head and the lower head respectively. After the inner tank is manufactured, it needs to be inserted into the outer tank, and a heat-insulating glass fiber reinforced plastic ring is installed between the inner and outer tanks for support. Such as figure 1 As shown, in order to insulate heat conduction, a glass steel ring 03 is installed between the lower head 01 of the inner tank body and the lower head 02 of the outer tank body, and the...
