Problems solved by technology

Due to the different lengths and sizes of the combustion chamber shells, it is necessary to design different raising devices to meet the interval size, which increases the production and management costs; the installation of raising devices often requires the operator to enter the depth of 5-8 meters by erecting a ladder In the pouring cylinder, there are safety risks; the residue and accumulation of slurry leakage, due to the impact and friction of metal objects during installation, may easily cause safety hazards such as fire

Abstract

The invention discloses a mounting and adjusting device for pouring of a solid propellant combustion chamber. The mounting and adjusting device comprises a pouring cylinder which is cylindrical and isprovided with the hollow interior, and the bottom of the pouring cylinder is provided with a hydraulic lifting platform. A plurality of guiding grooves are uniformly distributed in the side wall of the pouring cylinder in the axial direction, a plurality of annular grooves are distributed in the side wall of the pouring cylinder in the radical direction, and the guiding grooves and the annular grooves are vertically formed in the inner side of the side wall in a staggered mode. The mounting and adjusting device further comprises a bearing disc, the bottom of the bearing disc is connected witha bearing beam, and the center of the bearing beam is provided with a bearing. The mounting and adjusting device is reasonable in structure, reliable in work and easy to operate, various potential safety hazards are completely eliminated, the number of tools is decreased, and the production cost and management cost of enterprises are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of solid propellant manufacture, and in particular relates to a pouring installation adjustment device for a solid propellant combustion chamber. Background technique [0002] Before propellant vacuum pouring, the combustion chamber shell needs to be installed on the raising device in the pouring cylinder by hoisting to ensure that the end face of the feed port of the combustion chamber shell in the cylinder and the discharge of the propellant pouring hopper Keep a certain interval between the ports, and in a vacuum environment, when the propellant slurry passes through this interval, the rapid removal of the residual gas in the interior is completed. Due to the different lengths and sizes of the combustion chamber shells, it is necessary to design different raising devices to meet the interval size, which increases the production and management costs; the installation of raising devices often requires the o...
