The invention discloses a single guide rail connecting device suitable for a top-driving device. The single guide rail connecting device comprises two connectors (7) fixed on connecting ends of a single guide rail respectively; each connector (7) consists of two parallel ear plates; the connecting device also comprises connecting blocks (8); the connecting plates (8) are inserted to between the ear plates of the connectors (7) and are in movable connection with two connectors (7) through two fixed pin rolls (9) positioned on one side respectively; when the single guide rail is furled, two sections of the adjacent single guide rails can rotate around the fixed pin rolls (9) to the parallel positions; when the single guide rail is assembled, the adjacent sections of the single guide rail rotate around the fixed pin rolls (9) to the positions in alignment; and at that time, the adjacent sections of the single guide rail are connected with two connectors (7) and the other side of the connecting block respectively through two movable pin rolls (10). The invention also discloses the single guide rail using the single guide rail connecting device.
Description
technical field [0001] The invention relates to a single guide rail connection device and the single guide rail, in particular to a top drive drilling device single guide rail connection device and the single guide rail. Background technique [0002] Top drive drilling rigs have become standard equipment for modern deep well drilling rigs. The single guide rail is an important component of the top drive device, which is used as a track for the top drive device to move up and down. Another function of the single guide rail is to transmit the reaction torque on the single guide rail to the drilling platform, so as to drive the make-up and breakout of the drill pipe. [0003] refer to figure 1 , is a schematic diagram of a single guide rail structure in the prior art. The single guide rail is composed of a single guide rail drop body 1a, a single guide rail bottom 2a, a single guide rail middle part 3a, a single guide rail connecting device 4a, a single guide rail top 5a, an...
