Abstract
The utility model relates to a well face mechanization idler wheel device for petroleum well repairing. The well face mechanization idler wheel device comprises an upper support, a lower support, a fastening piece, a jackscrew block, a rolling mechanism, an idler wheel and a sliding way. One end of the upper support is connected with an elevator. The other end of the upper support is connected with the lower support through the fastening piece. The lower support is connected with the jackscrew block through the fastening piece. The jackscrew block is fixed on the rolling mechanism. The idler wheel is arranged on the end portion of the rolling mechanism. The sliding way is fixed at a well opening. The idler wheel is arranged in the sliding way. A limiting idler wheel is arranged on the end portion of the rolling mechanism. The well face mechanization idler wheel device has the advantages that the elevator moves according to a set track, the elevator can be accurately aligned with the center of the well opening, and meanwhile safety and reliability of elevator operation are improved.
