The invention discloses an automatic stereoscopic drill rod warehouse. According to the automatic stereoscopic drill rod warehouse, a pair of inverted-U-shaped guide rails are mounted at each of the positions, close to the outer edge, of the two longitudinal ends of a rack respectively, two sets of chain wheels are mounted between the guide rails at each end, each set of chain wheels is sleeved with a chain, the two chains at each end are wound around the ends, close to the outer end edges, of the corresponding chain wheels and connected with a balancing rod jointly downwards, each balancing rod is connected with piston rods of two lifting oil cylinders downwards at the same time, and the lower ends of cylinder bodies of the two lifting oil cylinders at each end are hinged to a lug seat on a bottom plate of the rack; the ends, close to the inner side, of the two chains at each end are sequentially fixed connected with a plurality of sets of drill rod frames downwards. The automatic stereoscopic drill rod warehouse is used for automatic treatment of tubular columns, and drill rods are conveyed between the automatic stereoscopic drill rod warehouse and a catwalk; overall hoisting is carried out, transportation is more convenient, all the drill rod frames are sequentially and vertically arranged, and the occupied space is small; automatic and unmanned operation can be achieved conveniently.
Description
technical field [0001] The invention belongs to the technical field of petroleum drilling equipment, and relates to an automatic three-dimensional drill pipe storage. Background technique [0002] In the auxiliary drilling operation, the delivery of the drill string is labor-intensive and time-consuming. In general pipe string processing, hydraulic row drill rod racks are arranged on both sides of the low-level catwalk. The existing common hydraulic drill pipe rack, single-layer discharge pipe string, and hydraulic cylinder support feet, by controlling the inclination angle, the pipe string rolls to the catwalk by gravity for drill pipe transmission. The disadvantages of this hydraulic row drill rod rack are: a single-layer discharge pipe string takes up a lot of space; the drill rods need to be laid on the drill rod rack in advance, and the drill rods should be stored in the sledge for placing the drill rods later; they cannot be transported as a whole.
