2. effectively slow down the drilling rod excessive swing in the drilling operation process, reduce the damage of dolly coupler. The utility model discloses simple structure easily makes, and is with low costs.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the utility model discloses a drill rod clearance adjustable roller drill small platform fixing bush, which comprises a bush body 1, and is characterized in that the bush also comprises an adjusting mechanism and a dustproof mechanism, wherein the adjusting mechanism is composed of a spring positioning bolt 31, a spring 32 and a positioning ball 33 which are connected in sequence; the dustproof mechanism consists of an upper dustproof rubber sheet A41, an upper dustproof fixing plate A42, a fastening bolt A43, a lower dustproof rubber sheet B51, a lower dustproof fixing plate B52 and a fastening bolt B53;
the bush body 1 is symmetrically provided with adjusting holes consisting of inner holes and outer holes, the inner holes are communicated with the outer holes, the inner holes are smaller than the outer holes, the positioning ball 33 of the adjusting mechanism is arranged at the inner hole of each adjusting hole, and the spring positioning bolt 31 is arranged at the outer hole; when the drill rod of the drilling machine is positioned with the bushing body 1, the clearance between the drill rod and the bushing body 1 is adjusted through the elasticity of the spring positioning bolt 31 and the adjusting spring 32.
The upper part of the bushing body 1 is provided with a groove 2, the groove 2 is provided with bolt holes, the outer rings of an upper dustproof fixing plate A42 and an upper dustproof rubber sheet A41 are also provided with corresponding bolt holes, the outer ring of the upper dustproof rubber sheet A41 is arranged on the groove 2, the upper dustproof fixing plate A42 is buckled and pressed on the upper part of the upper dustproof rubber sheet A41, and the upper dustproof fixing plate A42 and the upper dustproof rubber sheet A41 are fixed in the groove 2 of the bushing body 1 at the edge through a fastening bolt A43;
