Opening and closing machine for ladle cover of casting machine

Abstract

The invention discloses an opening and closing machine for a ladle cover of a casting machine, and relates to the technical field of opening and closing machines. The opening and closing machine comprises a stand column, wherein a mounting sleeve is arranged on the stand column, a hydraulic cylinder is hinged to the mounting sleeve, a transverse arm is rotationally connected to the top end of thestand column, the output end of the hydraulic cylinder is hinged to one end of the transverse arm, the top end of the stand column is fixedly provided with a limiting disc, a shaft hole is formed in the middle of the limiting disc, a mounting hole is formed in the limiting disc, limiting grooves are formed in the edge of the limiting disc in a circular array mode, limiting columns matched with thelimiting grooves in a sliding mode are arranged on the transverse arm, and an extension arm is arranged at one end of the transverse arm. According to the opening and closing machine, the transversearm is driven by utilizing the hydraulic cylinder hinged to the stand column, so that the rotation of the transverse arm on the stand column is realized; and the limiting disc is fixed on the stand column, and the limiting columns on the transverse arm are slidably matched in the limiting disc, so that the control effect on the rotating amplitude of the transverse arm is enhanced, moreover, the structure stability and the structure are high, the production cost is low, and the cost performance is improved.

Description

technical field [0001] The invention belongs to the technical field of hoisting machines, in particular to a hoisting machine for a pouring machine cover. Background technique [0002] The hoist is used to control the lifting of various large and medium-sized cast iron gates and steel gates to achieve the purpose of opening and closing. [0003] At present, the structure of the hoist used for the cover of the pouring machine is relatively complicated, and the structural stability is not strong, which easily causes the hoist to be easily damaged, which not only increases the installation cost of the hoist, but also increases the maintenance of the hoist Cost, when the hoist is damaged, it is also easy to pose a threat to the safety of the staff. Contents of the invention [0004] The object of the present invention is to provide a gate hoist for pouring machine cover. By using the hydraulic cylinder hinged on the column to drive the cross arm, the rotation of the cross arm...

Problems solved by technology

[0004] The object of the present invention is to provide a gate hoist for pouring machine cover. By using the hydraulic cylinder hinged on the column to drive the cross arm, the rotation of the cross arm on the column is realized, and the limit plate is fixed on the column. , and the limit column on the cross arm is slidably fitted in the limit plate, which enhances the control effect on the rotation range of the cross arm, and by installing a hook on the cross bar of the extension arm, the cover body is realized. Grab, and the structural stability and structure are strong, the production cost is low, the cost performance level is improved, and the problem of the current structure stability of the hoist used for the cover of the pouring machine is not strong.
