Utility model content
For solving the problem, the utility model provides a kind of caliper arrangement for drilling rod dismounting, its use safety.
For achieving the above object, caliper arrangement for drilling rod dismounting of the present utility model, it is installed on boring tower pedestal, described boring tower pedestal offers installing hole, wherein, a pair block that described caliper arrangement comprises drilling rod fork pedestal, drilling rod fork, a pair oil cylinder and is fixed on described boring tower pedestal
Described drilling rod fork pedestal is between described a pair block, it is connected with described boring tower pedestal rotationally by the extension extended in described installing hole, when described drilling rod fork pedestal rotates, it can clash into described a pair block, described drilling rod fork pedestal offers the datum hole of through described extension;
Described drilling rod fork pedestal is provided with for pitching the guide rail led to drilling rod, and one end of described a pair oil cylinder is all pitched pedestal with described drilling rod and is connected, and the other end is all pitched with described drilling rod and is connected.
Preferably, described caliper arrangement also comprises abutment sleeve, and described abutment sleeve is installed in described datum hole.
Preferably, described extension extends the soffit of described boring tower pedestal, described extension is fixed with the spacing back-up ring deviate from described installing hole for preventing described drilling rod from pitching pedestal.
Preferably, described spacing back-up ring welds mutually with described extension.
Caliper arrangement for drilling rod dismounting of the present utility model, drilling rod fork is all installed on drilling rod with a pair oil cylinder and pitches on pedestal, can ensure the reliability of drilling rod fork and oil cylinder.Especially, when drilling rod moves up or down due to maloperation, main stressed member is drilling rod fork pedestal but not oil cylinder, therefore, it is possible to ensure the use safety of oil cylinder.Spacing back-up ring is set in the bottom of drilling rod fork pedestal, can prevents drilling rod from pitching pedestal and depart from from boring tower pedestal.This caliper arrangement of the present utility model, structure is simple, easy to use.

Detailed description of the invention
Below, by reference to the accompanying drawings, structure of the present utility model and operating principle etc. are further described.
See Fig. 2, the caliper arrangement for drilling rod dismounting of the present utility model, it is installed on boring tower pedestal 6, wherein, boring tower pedestal 6 offers installing hole (not indicating in figure).A pair block 4 that this caliper arrangement comprises drilling rod fork pedestal 1, drilling rod fork 2, a pair oil cylinder 3 and is fixed on boring tower pedestal 6.
Drilling rod fork pedestal 1 is between a pair block 4, and shown in composition graphs 4, be provided with extension 101 below drilling rod fork pedestal 1, this extension 101 extends in installing hole, and by this extension, drilling rod fork pedestal 1 is connected rotationally with boring tower pedestal 6.And, as shown in FIG., when drilling rod fork pedestal 1 rotates, it can strike a pair block 4, particularly, when drilling rod fork pedestal 1 rotates clockwise, it can strike the block 4 being arranged in figure right side, and when drilling rod fork pedestal 1 rotates counterclockwise, it can strike the block 4 being arranged in figure left side, thus loosen, tighten moment for the drilling rod be installed in drilling rod fork pedestal 1 provides, complete the dismounting of drilling rod.Drilling rod fork pedestal 1 offers the datum hole (not indicating in figure) of through extension, namely this datum hole pitches the upper surface of pedestal to downward-extension by drilling rod, through extension.
2 are pitched when stretching out for making drilling rod, its prong 201 just to datum hole, drilling rod fork pedestal 1 can be provided with the guide rail (not indicating in figure) for leading to drilling rod fork 2, like this, drilling rod fork 2 can move along set guide rail, thus ensures its movement locus.
See Fig. 2, Fig. 3, one end of a pair oil cylinder 3 is all pitched pedestal 1 with drilling rod and is connected, and the other end is all pitched 2 with drilling rod and is connected.This mode, when drilling rod fork 2 pitches drilling rod, drilling rod due to maloperation move up or down time, main stressed member is drilling rod fork pedestal 1 but not oil cylinder 3, can available protecting oil cylinder.Oil cylinder 3 and drilling rod pitchs pedestal 1 and drilling rod and are pitched 2 and adopt such connected mode, and the cylinder body 301 of oil cylinder 3 passes through the bearing pin of end and drilling rod, and to pitch pedestal 1 hinged, and the piston rod 302 of oil cylinder 3 is pitched 2 hinged by the bearing pin of end and drilling rod.When piston rod 302 stretches out, drilling rod fork 2 is away from datum hole, and when piston rod 302 is retracted, drilling rod fork 2 is near datum hole.As a kind of mode, a pair oil cylinder 3 is arranged in parallel.
For ensureing that drilling rod is limited in the center of datum hole all the time, caliper arrangement also comprises abutment sleeve 5, and abutment sleeve 5 is installed in datum hole.
Continue as shown in Figure 4, pitch pedestal 1 for preventing drilling rod and deviate from installing hole, in the utility model, extension 101 extends the soffit of boring tower pedestal 6, extension 101 is fixed with spacing back-up ring 9, and this spacing back-up ring 9 can weld mutually with extension 101.
Below, composition graphs 3, is described the operating principle of this caliper arrangement of the present utility model.During use, pitched by the second drilling rod 8 being positioned at downside by drilling rod fork 2, swivel head (not shown) drives the first drilling rod 7 being positioned at upside to rotate, and the first drilling rod 7 drives the second drilling rod 8 together to rotate.Pitch 2 due to the second drilling rod 8 and drilling rod to define face and contact, therefore it drives drilling rod fork pedestal 1 to rotate by drilling rod fork 2, drilling rod fork pedestal 1 clashes into a pair block 4, thus produces getting loose or Tightening moment relative to the first drilling rod 7 to the second drilling rod 8, completes the dismounting of the two.
Above, be only schematic description of the present utility model, it will be recognized by those skilled in the art that on the basis of not departing from operating principle of the present utility model, can make multiple improvement to the utility model, this all belongs to protection domain of the present utility model.
