Description

Technical Field

[0001] The utility model relates to the technical field of drill rods, in particular to a drill rod with a visual function for coal mine drilling tool salvage construction. Background Art

[0002] Due to the complex coal seam conditions or the quality of drilling tools, accidents such as drill sticking, drill binding or drill breakage are inevitable during the drilling construction process. The bottom hole motor and drill rod of the directional drilling rig are expensive, causing huge losses. Therefore, the drill bit is often salvaged by using a salvage drill rod through the thread.

[0003] For example, the utility model: "A drill rod for salvaging underground drilling tools in coal mines", with the announcement number: "CN213684008U", sets up multiple gas paths and air holes to allow high-pressure gas to be ejected from the air holes. The gas ejected from the air holes impacts the inner wall of the borehole, so that the salvage section is located at the center of the borehole, thereby aligning the center line of the salvage section with the center line of the middle section, making the docking of the salvage section and the middle section more convenient and more accurate, thereby improving the speed and efficiency of the docking. However, during the implementation of the patent, since it does not have a visual function, it is not convenient for the staff to observe the salvage situation of the drill bit, thereby making it inconvenient to carry out the salvage work. Therefore, the utility model provides a drill rod with a visual function for salvaging underground drilling tools in coal mines to solve the above-mentioned problem. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides an embodiment: a drill rod with visual function for coal mine drilling tool salvage construction, comprising a drill bit 1, a salvage pipe 4 and an intermediate rod 6, the bottom of the salvage pipe 4 is installed with the intermediate rod 6, and the bottom of the intermediate rod 6 is installed with the drill bit 1, the top of the intermediate rod 6 is provided with a first mounting screw hole 7, and the bottom of the intermediate rod 6 is provided with a second mounting screw hole 8, the inside of the salvage pipe 4 is installed with a mounting ring 5, and the inside of the mounting ring 5 is installed with a mounting plate 13, the bottom of one end of the salvage pipe 4 is provided with a through opening 20, the bottom of the mounting plate 13 is provided with a first sliding component 16 near the through opening 20, and the bottom of the first sliding component 16 is slidably installed with an L-shaped plate 17, a camera 19 is installed inside the L-shaped plate 17, the top of the mounting plate 13 is installed with a mounting pipe 14 at one end away from the through opening 20, and the inside of the mounting pipe 14 is installed with a pushing rod 12, the pushing rod 12 passes through the mounting plate 13 and extends to the outside of the mounting ring 5.

[0022] In this implementation:

[0023] Furthermore, a connecting rod 11 is hinged on the outer side of the pushing rod 12, and one end of the connecting rod 11 away from the pushing rod 12 is hinged to the L-shaped plate 17. The pushing rod 12 drives the connecting rod 11 to move together, so that the connecting rod 11 is subjected to force and pushes the L-shaped plate 17 to move, and the camera 19 can be pushed out from the inside of the salvage tube 4 for monitoring.

[0024] Furthermore, a fixing plate 9 is installed at the bottom of the end of the salvage tube 4 away from the opening 20, and a return spring 10 is installed on the top of the fixing plate 9. The end of the return spring 10 away from the fixing plate 9 is connected to the pushing rod 12. After use, the return spring 10 can push the pushing rod 12 to move upward and reset, so that the connecting rod 11 pulls the L-shaped plate 17 to move and reset, and the camera 19 can be stored in the salvage tube 4.

[0025] Furthermore, a second threaded rod 3 is installed at the bottom of the salvage pipe 4. The second threaded rod 3 is screwed into the first mounting screw hole 7, so that the intermediate rod 6 and the salvage pipe 4 can be firmly installed.

[0026] Furthermore, a second sliding component 21 is installed at one end of the mounting tube 14 away from the through-hole 20, and a slider 15 is slidably installed at one end of the second sliding component 21 close to the through-hole 20. The end of the slider 15 away from the second sliding component 21 is connected to the pushing rod 12. The mounting plate 13 is limited by the slider 15 so that the pushing rod 12 can only move in a straight line in the vertical direction.

[0027] Furthermore, a first threaded rod 2 is installed on the top of the drill bit 1. After the first threaded rod 2 is inserted into the second mounting screw hole 8, the salvage pipe 4 drives the intermediate rod 6 to rotate, so that the first threaded rod 2 can be screwed into the second mounting screw hole 8, and the drill bit 1 can be installed in the intermediate rod 6, and the drill bit 1 can be fished out from the inside of the well.

[0028] Furthermore, a sealing baffle 18 is installed at one end of the L-shaped plate 17 away from the first sliding assembly 16 , and the sealing baffle 18 blocks the through opening 20 , thereby preventing coal debris in the well from entering the inside of the salvage pipe 4 .

[0029] Working principle:

[0030] When in use, the device is powered on, and the second threaded rod 3 is screwed into the first mounting screw hole 7, so that the intermediate rod 6 and the salvage pipe 4 can be firmly installed;

[0031] When the drill bit 1 is salvaged, the intermediate rod 6 can be driven to move into the well through the salvage pipe 4. After the first threaded rod 2 is inserted into the second mounting screw hole 8, the salvage pipe 4 drives the intermediate rod 6 to rotate, and the first threaded rod 2 can be screwed into the second mounting screw hole 8. The drill bit 1 can be installed in the intermediate rod 6, and the drill bit 1 can be salvaged from the well.

[0032] During the salvaging process, the staff can move the push rod 12 downward, the push rod 12 compresses the return spring 10, and the push rod 12 drives the connecting rod 11 to move together, so that the connecting rod 11 is stressed and pushes the L-shaped plate 17 to move, and the L-shaped plate 17 and the camera 19 can be pushed out from the inside of the salvaging tube 4. The salvaging situation can be monitored through the salvaging tube 4, so that the staff can watch the salvaging process through the external display, thereby facilitating the salvaging of the drill bit 1;

[0033] After use, the staff no longer pushes the pushing rod 12. At this time, the elastic action of the reset spring 10 pushes the pushing rod 12 to move upward and reset. The pushing rod 12 drives the connecting rod 11 to move together, so that the connecting rod 11 is stressed and pulls the L-shaped plate 17 to move and reset. The L-shaped plate 17 drives the camera 19 and the sealing baffle 18 to move together, so that the camera 19 can be stored in the inside of the salvage pipe 4, and the through hole 20 can be blocked by the sealing baffle 18, so as to prevent the coal debris in the drilling well from entering the inside of the salvage pipe 4 when the drill bit 1 is taken out.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
