Abstract: An inner and outer tank connection device for a cryogenic storage tank includes a suspension belt; a first connection assembly for connecting the outer tank, wherein the first connection assembly includes a first connection seat and a first connection member, and the first connection seat is configured for connecting the outer tank and the first connection seat is provided with a first limiting seat, the first connection member is rotatably connected to one end of the suspension belt, and the first connection member is provided with a first limiting portion, and the first limiting portion fits with the first limiting seat to limit the first connection member from twisting on the first connection seat with the suspension belt as a rotation axis; and a second connection assembly for connecting the inner tank, wherein the second connection assembly is rotatably connected to another end of the suspension belt.

Abstract: A cryogenic storage tank includes an inner tank, a shell and two support assemblies supported between the inner tank and the shell. The two support assemblies are provided on two opposite ends of the inner tank along the axis of the inner tank. The support assemblies all include a plurality of support members, and the plurality of support members of each support assembly are symmetrically provided with respect to the vertical centre axis plane of the inner tank, and each of the upper side and the lower side of the horizontal centre axis plane of the inner tank is provided with support members; each support member includes an inner end connected to the outer end of the inner tank and an outer end connected to the inner wall of the shell, and the support member is located in a different plane from the axis of the inner tank.

Abstract: A low-temperature container, low-temperature tank and low-temperature tank truck are provided. The low-temperature container includes a housing and an inner container disposed inside the housing through a support assembly. The support assembly includes two transverse support structures correspondingly disposed between the housing body and inner container body, and two longitudinal support structures respectively disposed between the outer sealing head and the inner sealing head located at ends. An central lines of the two longitudinal support structures and an central axis of the inner container are collinear, or the central lines of the two longitudinal support structures are parallel to the central axis of the inner container, and the longitudinal support structures may extend and retract in the longitudinal direction of the low-temperature container. The low-temperature container of the present disclosure has balanced support points and good heat insulation effect.

Abstract: A tank type container, comprising a tank (1), two end frames (2) respectively fixed at two ends of the tank (1), and at least one saddle (3) located at the bottom of the outer wall of the tank (2); an upward concave gooseneck hole (27) is formed in the bottom of the saddle (3) for insertion of the gooseneck of a semitrailer front end; and at least one saddle (3) is adjacent to one of the end frames (2), and forms a gap with the end frame (2). The saddle (3) and the end frame (2) are spaced a certain distance, thus greatly shortening the length of the saddle (3), reducing the manufacturing cost of the saddle (3) as the gooseneck hole, reducing the dead weight of the entire vehicle, and improving the competitiveness of the product.

Abstract: The present invention provides apparatus and a method for projecting an indication of alignment. The invention features forming a first output beam, and a second output beam that is substantially perpendicular to the first output beam. The first output beam indicates level, the second output beam indicates plumb, and the first and second output beams together indicate square.

Abstract: A tank container for transporting and storing liquefied gas, including a tank that includes a cylinder body and two heads arranged oppositely and welded with both ends of the cylinder body; and a frame assembly for fixing and supporting said tank, which includes a front frame and a rear frame fixed at both ends of said tank respectively. The cylinder body has a shell thickness ? substantially equal to: Pc×Di/(2?b/Ks?Pc), wherein, Pc is the calculated pressure of the tank, required by the transported liquefied gas, Di is the inner diameter of the cylinder body, ?b is the maximum tensile strength of material of the cylinder body at a normal temperature, and Ks is a safety factor no larger than 2.6. The tank container is designed through stress analysis methods, the safeness of which has been verified.
