Auxiliary device for hatch cover steel bushing installation and method of use thereof

Abstract

The invention discloses an auxiliary device for installation of a steel bushing of a hatch cover and an application method of the auxiliary device. The device comprises a portal clamp plate, a bracket back plate, a bracket support plate I and a bracket support plate II, wherein the bracket support plate I is connected with the bracket back plate through a hinge; the bracket support plate II is arranged on the bracket support plate I; bracket baffles are arranged on the left and right positions of the bracket support plate II. The method comprises the following steps: clamping the portal clamp plate of the device on a hinge plate of the hatch cover, regulating a vertical adjustment bolt to make the bracket support plate I to be perpendicular to the bracket back plate, regulating the positions of the two bracket baffles to make the two bracket baffles to be tangent with the outer end face of a shaft sleeve hole of the hinge plate, putting the steel bushing after being subjected to freezing into the device and between the two bracket baffles, and pushing the steel bushing into the shaft sleeve hole of the hinge plate by hands of an operator wearing dedicated gloves. By applying the auxiliary device, the steel bushing can be pushed into the shaft sleeve hole of the hinge plate rapidly, the assembly quality of the steel bushing of the hatch cover is effectively improved, and the installation time is shortened.

Description

technical field [0001] The invention relates to an auxiliary device for the installation of hatch cover steel bushings and a method of use thereof. Background technique [0002] The production practice at home and abroad shows that carrying out precision management of hull construction plays an important role in shipbuilding enterprises, ship owners, employees, society and national defense construction. With the development of shipbuilding technology, precision shipbuilding technology has a major role in promoting the economic benefits and market competitiveness of shipbuilding enterprises. Hatch cover production is a systematic project in the hull construction process, and its quality is directly related to the image of the company. Among them, the hatch cover steel bushing is required to be installed in interference fit with the shaft sleeve hole of the hinge plate. The bushing is cooled to -180°C to shrink the steel bushing, and then it is installed into the shaft sleeve...

AI Technical Summary

Problems solved by technology

Hatch cover production is a systematic project in the hull construction process, and its quality is directly related to the image of the company. Among them, the hatch cover steel bushing is required to be installed in interference fit with the shaft sleeve hole of the hinge plate. Cool the bushing to -180°C to shrink the steel bushing, and then install it into the shaft sleeve hole of the hinge plate. The entire loading process must be controlled within a few seconds, otherwise the assembly quality cannot be guaranteed

During the assembly process of the steel bushing of the hatch cover, in order to prevent the freezing injury of hands caused by the low-temperature liquid nitrogen, the operators wear special gloves for operation. The quasi-shaft sleeve hole often leads to improper assembly and the steel bushing needs to be knocked out of the hole, resulting in a very common waste of labor and materials
