Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a drill rod conveying trolley for calcium carbide production. Background Art

[0002] Calcium carbide is an important basic chemical raw material and a key raw material for the production of polyvinyl chloride, 1,4-butanediol, vinyl acetate, calcium cyanamide, chloroprene rubber and other products. With the requirements of safety and environmental protection policies in recent years, most domestic calcium carbide production enterprises have replaced the traditional manual furnace opening with remote-controlled robots. The remote-controlled equipment integrates functions such as carbon rod eye opening, furnace tongue cleaning, and drill rod straightening. That is: when the furnace is ready, first use a carbon rod to burn the furnace eye and then use a drill rod to poke the furnace eye. When the flow rate of liquid calcium carbide is slow, use the drill rod to clear the furnace eye. After the calcium carbide flows out, use a burner carbon rod to burn the furnace eye into a regular shape, and then use a plugging machine to spray calcium carbide powder to plug the furnace eye. During daily use, the above-mentioned drill rod needs several workers to carry it from the processing workshop in the factory to the calcium carbide furnace discharge robot. However, since the drill rod is heavy, generally with a length of 12 meters and a weight of 267 kilograms, manual transportation is time-consuming and labor-intensive, and the transportation efficiency is low. In addition, it is easy to cause personal injury accidents such as mechanical squeezing and crushing to the workers during the transportation process. Utility Model Content
