A square culvert socket ring manufacturing frame

Abstract

The invention provides a square culvert socket ring manufacturing frame, and provides the square culvert socket ring manufacturing frame with the advantages that the structure is simple, the square culvert socket ring manufacturing frame is applicable to various heights, and the socket ring dimension precision can be improved. The square culvert socket ring manufacturing frame comprises a bottom frame, four groups of annular baffle plates and a plurality of position limiting baffle plates, wherein a support device comprises a sliding plate, a top plate fixing plate, at least two groups of sliding jacking structures, a pair of support plates and a plurality of top plate structures, the sliding plate and the top plate fixing plate are in parallel arrangement, the pair of support plates is arranged between the sliding plate and the bottom frame, the top plate structures are arranged on the top plate fixing plate, at least two groups of sliding grooves are formed in the sliding plate, guide grooves are respectively formed in the two sides of the sliding grooves, a plurality of guide holes are formed in the top plate fixing plate, and the sliding jacking structure comprises a sliding sleeve, a fixing sleeve, a jacking screw bolt, a fixed screw nut and a plurality of sliding springs. The square culvert socket ring manufacturing frame has the advantages that the dimension precision of a socket ring after the welding is improved, and the one-step welding qualification rate can be improved.

Description

technical field [0001] The invention relates to a manufacturing frame, in particular to a manufacturing frame for square culvert socket rings. Background technique [0002] The square culvert socket ring is used to connect two square culverts into one and form a sealed structure at the joint. Since square culverts are generally laid underground and used for line or pipeline routing, the volume of square culverts is generally large and is used for The volume of the square culvert socket ring connecting the square culvert is also relatively large, and the square culvert socket ring is generally welded by four arc steel plates and four straight steel plates. During the production process, the positioning is inaccurate due to its heavy weight, which makes the welded socket ring less precise and difficult to fit into the square culvert, making construction more difficult. Contents of the invention [0003] Aiming at the above problems, the present invention provides a square c...
