Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, and more specifically, to a drill pipe supply device. Background Technology

[0002] As one of my country's main energy sources, safe coal mining has always been a key focus. Coal mines typically contain methane gas, which gradually releases and accumulates within the mine as mining progresses, posing safety hazards. Therefore, drilling rigs are used for preliminary exploration, sampling, and methane drainage. This process involves drilling into the coal seam. A drilling rig mainly consists of a drilling assembly and a drill rod supply device. The drill rod supply device comprises a supply component and a gripping component. The gripping component picks up the drill rod from the supply component and supplies it to the drilling assembly, thus enabling the drilling operation.

[0003] However, during the drilling process, as drilling continues, coal slag will fall off the coal seam and land on the feed assembly of the drill rod feeder. Excessive coal slag will fill the gaps on the feed assembly, thereby reducing the operating space for the gripping assembly to grip the drill rod and affecting the normal operation of the drill rod feeder.

The drill rod supply device can grip the drill rod 21 in the supply component 02 using the gripping component 03 and place the drill rod 21 on the drilling rig. However, during drilling, coal slag may fall from the coal seam into the gaps in the supply component 02, preventing the gripping component 03 from gripping the drill rod 21. This embodiment provides a drill rod supply device, such as... Figure 1As shown, the drill pipe supply device may include a supply assembly 02, a base assembly 01, and a gripping assembly 03. The supply assembly 02 may include a drill pipe 21 and a storage unit 22; the storage unit 22 may include a base plate 222, a first side plate 224, a second side plate 225, a support rod 221, and multiple partitions 228; the first side plate 224 is detachably connected to the base plate 222, and the second side plate 225 is detachably connected to the base plate 222; the first side plate 224 and the second side plate 225 may be spaced apart to form a receiving area; one end of some partitions 228 is detachably connected to the first side plate 224; one end of another part of the partitions 228 is detachably connected to the second side plate 225. Side plates 225 are detachably connected; partitions 228 can be disposed within the accommodating areas of the first side plate 224 and the second side plate 225; multiple partitions 228 can be arranged sequentially at intervals, thereby forming multiple interval areas within the accommodating area, allowing the drill rod 21 to be neatly placed, facilitating the gripping unit 32 to grip the drill rod 21; one end of the drill rod 21 can be disposed within the interval area between the two partitions 228 near the first side plate 224; the other end of the drill rod 21 can be disposed within the interval area between the two partitions 228 near the second side plate 225; Figure 3 As shown, the support rod 221 is detachably connected to the base plate 222; multiple support rods 221 can be arranged within the accommodating area; the drill rod 21 can abut against the end of the support rod 221 away from the base plate 222; the angle formed by the center line of the support rod 221 along its length and the center line of the drill rod 21 along its length is greater than a set angle; by setting the support rod 221, a gap can exist between the drill rod 21 and the base plate 222, thereby preventing slag from filling the gap between the drill rods 21 when it falls onto the base plate 222 of the storage unit 22, thus preventing the gripping unit 32 from gripping the drill rod 21. The base assembly 01 and the supply assembly 02 are detachably connected to the base assembly 01; the gripping assembly 03 is detachably connected to the base assembly 01; the drill rod supply device can include a supply state; the supply state can include the gripping assembly 03 gripping the drill rod 21 from the supply assembly 02 and moving it to a set position, thereby enabling the drill rod supply device to supply the drill rod 21.

[0030] In this embodiment, the storage unit 22 may include a plurality of first slag discharge holes 223; the plurality of first slag discharge holes 223 may penetrate the bottom plate 222. By setting the first slag discharge holes 223, some coal slag can be discharged from the first slag discharge holes 223, preventing excessive coal slag in the storage unit 22 from filling the gap between the drill rod 21 and the bottom plate 222, thus preventing the gripping unit 32 from gripping the drill rod 21.

[0031] In this embodiment, the gripping component 03 may include a second rotating unit 31, a gripping unit 32, a second moving unit 33, and a third moving unit 34; the gripping unit 32 is detachably connected to the second rotating unit 31; the second rotating unit 31 is detachably connected to the second moving unit 33; the second moving unit 33 is detachably connected to the third moving unit 34; the second moving unit 33 may include a second guide rail 331 and a second slide 332; the second guide rail 331 may be slidably connected to the second slide 332; the third moving unit 34 may include a third guide rail 341 and a third slide 342; the third guide rail 341 and the third slide 342 may be slidably connected; the second slide 332 may move in a vertical direction; the second guide rail 331 and the third guide rail 341 may be vertically arranged; by the vertical arrangement of the second guide rail 331 and the third guide rail 341, the gripping unit 32 can adjust its position through the second moving unit 33 and the third moving unit 34, making it easier for the gripping unit 32 to accurately grip the drill rod 21.

When the gripping unit 32 grips the drill rod 21, the drill rod 21 can be moved by the second moving unit 33 and the third moving unit 34, so that the drill rod 21 can be moved to a set position. At the same time, the drill rod 21 can be rotated by the second rotating unit 31, so that the drill rod 21 can be adjusted to a vertical state, so that the drill rod 21 can be placed on the set position of the drilling rig, thereby realizing the drilling work of the coal seam.

[0033] In this embodiment, as Figure 4As shown, the third moving unit 34 may further include a fixed plate 343; the fixed plate 343 may be fixedly connected to the third guide rail 341; the gripping assembly 03 may further include a slag discharge unit 35; the slag discharge unit 35 may include a plurality of second slag discharge holes 351, which may be arranged near the travel distance of the fixed plate 343; the plurality of second slag discharge holes 351 may penetrate the fixed plate 343. When the drilling rig is working, slag may fall onto the fixed plate 343, thereby affecting the movement of the third slide table 342. By providing second slag discharge holes 351 on the fixed plate 343, the slag can be discharged through the second slag discharge holes 351, preventing the slag from affecting the sliding of the third slide table 342.

[0034] In this embodiment, the slag discharge unit 35 may further include two jet nozzles 352; one jet nozzle 352 is detachably connected to one end of the third slide 342; the other jet nozzle 352 is detachably connected to the other end of the third slide 342; the airflow of the jet nozzle 352 can flow towards the fixed plate 343. By providing the jet nozzles 352, the slag falling on the fixed plate 343 can be cleaned by the jet nozzles 352, further preventing the slag on the fixed plate 343 from affecting the sliding of the third slide 342.

[0035] In this embodiment, the accommodating area may include at least two support rods 221 to further ensure that there is a gap between the drill rod 21 and the base plate 222, preventing the drill rod 21 from directly contacting the base plate 222.

[0036] In this embodiment, the supply component 02 may further include a reset unit 23; the reset unit 23 is detachably connected to the base plate 222; the reset unit 23 may include two support portions 231 and two reset slots 233; the support portions 231 are detachably connected to the reset slots 233; the two support portions 231 may be spaced apart, one support portion 231 may be located at the end of the base plate 222 near the first side plate 224; the other support portion 231 may be located at the end of the base plate 222 near the second side plate 225;

Since the drill rod 21 may be shifted due to coal slag or other contaminants, the reset unit 23 can be used to re-grip the drill rod 21, ensuring that the gripping unit 32 can place the drill rod 21 at the set position on the rotary table 134.

[0038] In this embodiment, as Figure 2As shown, the reset unit 23 may further include two inclined portions 232. The two inclined portions 232 may be fixedly connected to the two reset slots 233 respectively. When the offset of the drill rod 21 is too large, during the process of placing the drill rod 21 in the reset slot 233, the inclined portions 232 can guide the drill rod 21, so that the drill rod 21 can be placed in the set position, further ensuring that the gripping unit 32 can place the drill rod 21 in the set position of the rotary table 134.

[0039] In this embodiment, multiple drill rods 21 can be arranged sequentially in the vertical direction along the interval area. This allows the drill rods 21 to be neatly arranged on the storage unit 22, increasing the number of drill rods 21 that can be placed in the storage unit 22.

[0040] In this embodiment, the angle between the inclined portion 232 and the central axis of the support portion 231 can be less than 75°, thereby enabling the inclined portion 232 to have a better guiding effect on the drill rod 21.

[0041] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
