Abstract

The utility model relates to an apparatus for lifting and loosening a buckle of a drilling machine, which is composed of a buckle lifting and loosening device which is arranged on an output shaft of a power head and a turnover pad plate which is arranged on an orifice device, and the utility model is matched with a special drilling rod. When the lifting drilling machine conducts screwing and discharging operation, through a T-shaped groove and a shifting block of the drilling rod on the lifting body, and through the match between a key groove of the lifting body and an upper sleeve shifting key and between the turnover pad plate and the shifting block of a pad ring of the drilling rod, automatic screwing and buckle loosening operation of the drilling rod can be completed in the lifting process. The utility model has the advantages of simple structure and convenient and practical performance, and the utility model can be widely used for installation and usage of a power head type drilling machine.

Description

Rig is carried drawing and is unloaded buckle device

The utility model relates to a kind of drilling equipment parts, specifically, is that a kind of power head dummy rig is carried drawing and unloaded buckle device.

Before this, such boring tool divides two types substantially.It is tapering geology screw thread that one, drilling rod connect screw thread, matching usedly tightens, the shackle instrument is very simple, original, and operating process is wasted time and energy for the work of prosthesis power; Its two, same drilling rod connects screw thread, supporting tool using be the hydraulic pressure or the electro-hydraulic device of complexity, though carry draw, easy to use when unloading the goods from the airplane, complex structure, the product cost is too high.

The purpose of this utility model be to provide a kind of operation simple in structure again very easily rig carry drawing and unload machine.

The utility model unloads machine and upset backing plate two parts are formed by carrying drawing, carry and draw the shackle device and be contained on the unit head lower contact drive sleeve by bearing pin, carry draw the shackle device by rotating shaft, go up cover, bearing holder (housing, cover), bearing and carry and draw body and form, bearing holder (housing, cover) is contained in the rotating shaft, on be sleeved on the bearing holder (housing, cover) outside, there is the key of dialling the lower end, and carries drawing body and being contained on the bearing holder (housing, cover) by bearing, carry and draw the body lower end one group of T type groove is arranged, upper end and last cover are combined with keyway.The upset backing plate divides two halves to be hinged on the opening arrangement force-bearing base, and there is the drilling rod via hole centre, on the upset backing plate one group of shifting block is arranged.

Draw borer drill rod top that the shackle device matches male joint, one group of shifting block and gasket ring are arranged with carrying, one group of shifting block is arranged on the gasket ring, there is female joint the lower end, and pin and box sub is a threaded engagement.

Adopt the utility model, under the situation that does not have complicated hydraulic pressure or electro-hydraulic device, by carry draw that the shackle device is carried on unit head or the decline process in upset backing plate, drilling rod between ingenious the cooperation, realize tightening automatically or shackle of drilling rod, simple in structure, practical.

The utility model is described in further detail below in conjunction with accompanying drawing:

Accompanying drawing 1 is carried drawing for rig and is unloaded the buckle device working state schematic representation;

Accompanying drawing 2 draws shackle device assembling schematic diagram for carrying;

Accompanying drawing 3 is a turning cushions board mounting structure elevation;

Accompanying drawing 4 is a turning cushions board mounting structure vertical view;

Accompanying drawing 5 is supporting drilling rod schematic diagram;

As shown in the figure, the utility model draws shackle device 1 and upset backing plate 3 two parts are formed by carrying, carry and draw the shackle device and be contained on the unit head lower contact drive sleeve 4 by bearing pin 5, carry draw the shackle device by rotating shaft 6, on overlap 7, bearing holder (housing, cover) 8, bearing 9 and carry and draw body 10 and form, bearing holder (housing, cover) is contained in the rotating shaft, on be sleeved on the bearing holder (housing, cover) outside, there is the key of dialling the lower end, carrying the lower end inwall that draws body has one group of T type groove, and upper end and last cover are combined with keyway.3 fens two halves of upset backing plate are hinged on the opening arrangement force-bearing base 11, and there is the drilling rod via hole centre, on the upset backing plate one group of shifting block 12 are arranged.

Draw borer drill rod 2 tops that the shackle device matches and male joint 21, one group of shifting block 22, gasket ring 23 are arranged, have one group of shifting block corresponding on it with carrying with upset backing plate shifting block.There is female joint 24 lower end, and pin and box sub matches with screw thread.

When carry draw drilling rod twist, when unloading operation, draw the shackle device with loading onto on the unit head output shaft to carry, unit head descends, the drilling rod top connection is inserted in carries and draw in the body, hand changes a low-angle, the drilling rod shifting block is entered carry and draw in the body T type groove, unit head rises, and drilling rod is carried drawing on the body and carried, therebetween, upset backing plate in aperture is turned on automatically by the shifting block of next root drilling rod, and then, unit head descends, the turning cushions sheet reset, next root drilling rod gasket ring drops on the upset backing plate, simultaneously, carries drawing to overlap on the shackle device to insert to carry and draws in the body keyway; The unit head moment of torsion is passed to carry and is drawn body and drilling rod, and the shifting block that next root drilling rod shifting block is reversed on the backing plate blocks, and rig begins to carry out the shackle operation.

Claims

1, a kind of rig is carried drawing and is unloaded buckle device, draw the shackle device and upset backing plate two parts are formed by carrying, carry and draw the shackle device and be contained on the unit head lower contact drive sleeve by bearing pin, it is characterized in that carrying draw the shackle device by rotating shaft, go up cover, bearing holder (housing, cover), bearing and carry and draw body and forms, bearing holder (housing, cover) is contained in the rotating shaft, on be sleeved on outside the bearing holder (housing, cover), there is the key of dialling the lower end, carry and draw body and be contained on the bearing holder (housing, cover) by bearing, carry and draw the body lower end one group of T type groove is arranged, upper end and last cover are combined with keyway; The upset backing plate divides two halves to be hinged on the opening arrangement force-bearing base, and there is the drilling rod via hole centre, on the upset backing plate one group of shifting block is arranged.

2, rig according to claim 1 is carried drawing and is unloaded buckle device, and male joint, one group of shifting block and gasket ring are arranged at the top that it is characterized in that the borer drill rod that matches with it, and one group of shifting block is arranged on the gasket ring, and there is female joint the lower end, public because of joint be threaded engagement.
