Description
Technical field
The utility model belongs to machinery manufacturing technology field, particularly a kind of elevating mechanism of semi-automatic pouring device.
Background technology
At present, essence casting (hot investment casting) industry still adopts in casting cycle is manually lifting casting ladle and is carrying out casting operation, not only labour intensity is large for this, security is not high, and operating personnel are subject to the baking of high temperature near the casting ladle of splendid attire high-temperature molten steel when it is warm, be easy to heatstroke, working environment is quite abominable.
The utility model content
The utility model provides the elevating mechanism of little, the safe and reliable semi-automatic pouring device of a kind of labour intensity in order to solve weak point of the prior art.
for solving the problems of the technologies described above, the utility model adopts following technical scheme: the elevating mechanism of semi-automatic pouring device, comprise casting ladle, also comprise travelling carriage, suspension bracket, tooth bar, gear, gearcase, upper connecting rod and two lower links, upper small end is rotationally connected by pressure bearing and travelling carriage bottom, suspension bracket upper end, upper connecting rod lower end is fixedly connected with, tooth bar vertically is slidably connected in suspension bracket, the suspension bracket lower end is fixedly connected with gearcase, gear is located in gearcase, tooth bar passes gearcase and gear is connected with a joggle, the upper end of two lower links is fixedly connected with the tooth bar lower end, two lower link lower ends all bend and are crotch, the casting ladle two ends are respectively equipped with a trunnion axis, two trunnion axis are located at respectively in a crotch, the central shaft of gear stretches out outside gearcase and is connected with handwheel.
The central shaft of described handwheel and gear is in transmission connection by flat key, and the central shaft of gear is provided with for the self-locking mechanism that limits the hand wheel rotating position.
Described casting ladle rear portion is provided with guard shield, and guard shield is positioned under handwheel, and guard shield top is connected on two lower links.
Adopt technique scheme, semi-automatic pouring device also to comprise support and be located at guide rail on support, rolling on guide rail and be connected with roller, the central shaft of roller is connected with the travelling carriage upper end.
guide rail is crisscross to be located on the support of erectting in the middle of the workshop, when carrying out casting operation, casting ladle built on stilts one segment distance also is fixed by self-locking mechanism, molten steel in smelting furnace is poured in casting ladle, a workman promotes handwheel, roller rolls along guide rail, so just the casting ladle that fills with molten steel can be transported to assigned address and can carry out casting operation, when casting operation, if the liquid outlet height of casting ladle is improper, can first unclamp self-locking mechanism, then rotate handwheel, rotate by the central shaft driven gear, the tooth bar of gear driven and its engagement moves up or down along suspension bracket, tooth bar drives casting ladle by two lower links and moves up and down, so just casting ladle can be adjusted to correct position, again self-locking mechanism is pinned handwheel.Guard shield plays the heat that reduces molten steel to workman's baking degree, and prevents that molten steel from spilling and injure the workman.
The utility model is simple in structure, reasonable in design, adopts gear to rotate and drives the principle of rack linear motion and the mode of running vehicle type rail transport, fully reduces labour intensity in the casting operation process, improves security reliability and operating efficiency.
