Still kettle machine for producing high-strength concrete pipe pile

Abstract

The invention discloses a still kettle machine for producing a high-strength concrete pipe pile. The still kettle machine comprises a fixed support, a cylinder is mounted on the top of the fixed support, a base is fixed on the top of one end of the cylinder, one end of the base is horizontally provided with an extension plate, the two ends of the bottom of the extension plate are symmetrically provided with hydraulic oil cylinders, a kettle door is hinged to the middle of one end of the cylinder, a fixing bar is fixedly connected to the middle of the outer side of the kettle door, a groove isformed in the middle of the fixing bar, and bearings are embedded in the two ends of the groove. By means of the still kettle machine for producing the high-strength concrete pipe pile, opening and closing of the kettle door are synchronously controlled by the hydraulic oil cylinders, one end of each hydraulic oil cylinder is connected with a rotating head in the middle of the outer side of the kettle door, when the angle is changed in the opening and closing process of the kettle door, a rotating shaft accordingly rotates under the effect of the bearings, and stable rotation of the kettle door is ensured; and by means of a notch, extrusion between the hydraulic oil cylinders and the fixing bar can be avoided, the opening and closing operation of the kettle door is easy, and the working efficiency of the still kettle is improved.

Description

technical field [0001] The invention relates to an autoclave, in particular to an autoclave machine for producing high-strength concrete pipe piles, and belongs to the technical field of concrete pipe pile processing equipment. Background technique [0002] Autoclave, also known as steam-cured kettle, is a large-scale pressure vessel equipment used for steaming of building products such as lime-sand bricks, fly ash bricks, aerated concrete blocks, new lightweight wall materials, and concrete pipe piles. pressure maintenance. At present, autoclave or steam-cured kettle is not only used in silicate building products, but also used in steam-cured products in the fields of chemical industry, medicine, rubber, wood, gypsum, glass, thermal insulation materials, textile industry, military industry, etc. It is an indispensable machine for the production and processing of concrete pipe piles. [0003] The opening and closing process of the autoclave door in the existing autoclave i...
