Description
Technical Field
The utility model belongs to the coal mine equipment field especially relates to a drilling rod device is got in location.
Background
In the underground drilling construction of a coal mine, phenomena of spray holes, hole collapse, drill sticking, drill losing and the like are frequently encountered, and the main reasons of the phenomena are that firstly, when the drill holes enter a coal seam gas concentrated stress zone, gas adsorbed by coal is suddenly desorbed, and drill sticking and drill clamping caused by the spray holes and the hole collapse are caused; secondly, the geological structure changes to cause hole blockage, so that drill clamping and drill clamping are caused; and thirdly, the drill rod is aged after being used for a long time, the drill rod cannot rotate along with the power of the drill, and the drill bit in the hole is forced to enter the coal body by the propelling force, so that the drill bit is easy to block. Once a drill clamping and clamping accident occurs, not only is great difficulty brought to construction and the success rate of taking out is low, hidden dangers are left during the working face extraction period, but also great economic loss can be caused, in order to avoid the loss, the drill clamping and clamping are often required to be taken out, a plurality of drill holes are formed around a clamped drill rod by a drilling machine in the current common method, the purpose of reaming the clamped drill rod is achieved, the clamped drill rod is loosened, then the drill rod is taken out by utilizing the power of the drilling machine, however, the method is time-consuming and labor-consuming, the successful drilling rate is low, and the effect is not ideal.
Disclosure of Invention
An object of the utility model is to provide a drilling rod device is got in location, the device take out by the clamp, by the drilling rod success rate height, and easy operation, labour saving and time saving.
In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a drilling rod device is got in location, includes drilling rod, hookup positioner, the pole body of drilling rod is close to two spacing retaining rings of drill bit portion interval fixedly connected with, hookup positioner, including first sleeve, second sleeve, first sleeve, second sleeve are fixed connection as an organic whole side by side, and first sleeve suit is located between two spacing retaining rings on the drilling rod.
The diameter of the limiting retainer ring is smaller than the diameter of a drill bit of the drill rod.
And the cylinder walls of the first sleeve and the second sleeve are provided with a plurality of slag discharge ports.
The first sleeve and the second sleeve are fixedly connected into a whole through the connecting plate, so that drill bits of the drill rods in the first sleeve and the second sleeve are not contacted.
The cross sections of the first sleeve and the second sleeve are hexagonal or circular.
And a plurality of notches are formed in the limiting retaining ring.
The utility model discloses simple structure, convenient to use can take out fast and be pressed from both sides, by the drilling rod, and relative and prior art get the brill method more swift, and the success rate is high, avoids various potential safety hazards because of pressing from both sides the brill, the card bores and arouses.

Detailed Description
Example 1
As shown in figure 1, a device for taking out a drill rod in a positioning mode comprises a drill rod 1 and a connecting and positioning device, wherein the rod body of the drill rod 1 is close to two limiting check rings 2 fixedly connected to the drill bit part at intervals, the diameter of each limiting check ring 2 is smaller than the diameter of a drill bit of the drill rod, the normal work of the drill rod is guaranteed, the connecting and positioning device comprises a first sleeve 3 and a second sleeve 4, the first sleeve 3 and the second sleeve 4 are fixedly connected side by side into a whole, and the first sleeve 3 is sleeved on the drill rod 1 and located between the two limiting check rings 2.
During the use, will connect 4 suits of positioner second sleeve on the pole body of the drilling rod 5 of being blocked in coal seam 10, then will the utility model discloses a drilling rod is installed on the rig, slowly creeps into, utilizes to be blocked or to be pressed from both sides the drilling rod right the utility model discloses a drilling rod carries on spacingly to will be blocked or by the space expansion around the clamp drilling rod, then extract earlier the utility model discloses a behind the drilling rod, recycle rig power and extract and be blocked or pressed from both sides the drilling rod.
Example 2
As shown in fig. 2, a device for taking out drill rod in a positioning manner, comprises a drill rod and a connecting and positioning device, wherein the rod body of the drill rod is close to two spacing check rings fixedly connected with the drill bit part at intervals, the diameter of each spacing check ring is smaller than the diameter of a drill bit of the drill rod, the normal work of the drill rod is guaranteed, the connecting and positioning device comprises a first sleeve 3 with a round section, a second sleeve 4, the first sleeve 3 and the second sleeve 4 are fixedly connected side by side into a whole, the first sleeve 3 is sleeved on the drill rod and positioned between the two spacing check rings, and a plurality of slag discharge openings 31 are formed in the wall of the first sleeve 3 and the second sleeve 4, so that the sleeves are prevented from being blocked by coal slag.
Example 3
As shown in fig. 3, a drilling rod device is got in location, including drilling rod 1, hookup positioner, the pole body of drilling rod 1 is close to two spacing retaining rings 2 of drill bit portion interval fixedly connected with, the diameter of spacing retaining ring 2 is less than the drill bit diameter of drilling rod, guarantee the normal work of drilling rod, hookup positioner, first sleeve 3 including the cross section for hexagonal barrel preparation, second sleeve 4, first sleeve 3, second sleeve 4 is fixed connection side by side as an organic whole, 3 suits of first sleeve are on drilling rod 1, be located between two spacing retaining rings 2, wherein first sleeve 3, be provided with a plurality of row cinder notch 31 on the section of thick bamboo wall of second sleeve 4, prevent that the cinder from blockking up the sleeve, the cross section is hexagonal first simultaneously, the second sleeve also is further favorable to preventing that the cinder from blockking up between drilling rod and sleeve.
Example 4
The utility model provides a drilling rod device is got in location, includes drilling rod 1, hookup positioner, the pole body of drilling rod 1 is close to two spacing retaining rings 2 of drill bit portion interval fixedly connected with, and the diameter of spacing retaining ring 2 is less than the drill bit diameter of drilling rod, guarantees the normal work of drilling rod, hookup positioner, including first sleeve 3, second sleeve 4, first sleeve 3, second sleeve 4 are as an organic whole through connecting plate 9 fixed connection side by side, and 3 suits of first sleeve are on drilling rod 1, are located between two spacing retaining rings 2. When some drilling needs to be deeply drilled or the device drill rod needs to be drilled to the same depth as the clamped or clamped drill rod, the distance between the first sleeve 3 and the second sleeve is limited by the connecting plate 9, so that the drill bits of the drill rod in the first sleeve and the second sleeve are not contacted, and the damage of the drill bit of the device is avoided.
