An oil coating conveying device for drill pipe

Abstract

The invention relates to an oil smearing and conveying device for a drill stem. The oil smearing and conveying device comprises oil smearing tables installed on the end portions of transition tables. The two transition tables are symmetrically located at the two ends of the drill stem. The two oil smearing tables are symmetrically located at the two ends of the drill stem. Each oil smearing table comprises an oil smearing box body, wherein an arc-shaped oil smearing plate is installed at an opening in the upper end of the oil smearing box body, and a soft oil smearing cushion is installed on the arc-shaped oil smearing plate and makes contact with oil in an inner cavity of the oil smearing box body. An oil storage tank is installed below each transition table and communicates with the corresponding oil smearing box body through an oil guide pipe. Oil inlet valve rods are installed at the connection ends of the oil smearing box bodies and the oil guide pipes through springs. The upper ends of the oil inlet valve rods penetrate the arc-shaped oil smearing plates and protrude out of the surfaces of the arc-shaped oil smearing plates. Oil inlet holes are formed in the lower ends of the oil inlet valve rods. The height of the portion, protruding out of the surfaces of the arc-shaped oil smearing plates, of the oil inlet valve rods is larger than or equal to the interval between the center axes of the oil inlet holes and the center axes of the oil guide pipes. A drill stem ejection device is arranged between the two oil smearing tables.

Description

technical field [0001] The invention relates to processing equipment for drilling rods for geological exploration, in particular to processing and conveying equipment for drilling rods. Background technique [0002] During the processing of the drill pipe, it needs to be continuously transported between adjacent stations. When the drill pipe is processed and transported to the storage station, the end of the drill pipe needs to be oiled and sealed with a protective cap to prevent the thread at the end of the drill pipe from rusting and being damaged during transportation. In the existing drill pipe conveying equipment, only the drill pipe is conveyed, which cannot be carried out together with the oiling operation, and the efficiency is low. On the same day, the applicant applied for a patent titled "A Device for Receiving and Conveying Drill Pipes". The improvement is that the oil in the oiling box needs to be replenished manually and cannot be automatically replenished, so...

In the existing drill pipe conveying equipment, only the drill pipe is conveyed, and it cannot be carried out together with the oiling operation, and the efficiency is low

On the same day, the applicant applied for a patent titled "A Device for Receiving and Conveying Drill Pipes". The other improvement is that the oil in the oiled box needs to be replenished manually and cannot be replenished automatically, so there is some inconvenience.
