Detailed Description
The following further describes embodiments of the present invention in order to facilitate further understanding of the present invention by those skilled in the art, and does not constitute a limitation to the right thereof.
A pipe searching follower shelf device comprises an active supporting plate 5 which is slidably arranged on a pipe searching centering slideway on a shackle centering bracket of a vehicle-mounted workover rig, wherein a passive supporting plate 11 is arranged on the active supporting plate 5, a telescopic yielding mechanism is arranged between the passive supporting plate 11 and the active supporting plate 5, the telescopic yielding mechanism comprises a vertical telescopic mechanism and a transverse yielding mechanism, the vertical telescopic mechanism comprises a plurality of vertical supporting springs 4, and the transverse yielding mechanism comprises a plurality of transverse non-yielding springs 3;
a vertical central shaft 2 is downwards arranged in the middle of the passive supporting plate 11, a circle of annular anti-return ring 10 is arranged on the upper surface of the active supporting plate 5 around the central shaft 2, the anti-return ring 10 is overlapped with the center of the central shaft 2, a plurality of transverse anti-return springs 3 are radially arranged between the anti-return ring 10 and the central shaft 2, and a mounting seat 12 used for being connected with a driving mechanism on a shackle centering bracket is arranged on the active supporting plate 5;
and the passive supporting plate 11 is provided with a mounting frame 1 for mounting a pipe searching auxiliary mechanism.
The driving support plate 5 is provided with a through hole 8 corresponding to the middle shaft 2, the middle shaft 2 penetrates through the through hole 8 downwards, the bottom end of the middle shaft 2 is provided with a support plate 7, a plurality of upward telescopic convex columns 6 which are propped against the lower surface of the driving support plate 5 are uniformly arranged along the circumference of the support plate 7, and the telescopic convex columns are arranged on the support plate through lower support springs 9.
The driving supporting plate 5 is provided with a sliding guide groove used for interaction on the shackle centering bracket.
