Description

Technical Field

[0001] This invention relates to the field of engineering technology, and in particular to a synchronous multi-directional hydraulic punching device and method. Background Technology

[0002] Hydraulic drilling refers to the use of water jets sprayed during drilling to flush out coal and methane from protruding coal seams or induce controllable small outbursts, thereby depressurizing the coal body, releasing methane, and eliminating the risk of mining outbursts. Currently, the hydraulic drilling construction process typically involves introducing high-pressure water into the drill rod and spraying it outward through a nozzle to form a high-pressure water jet. The cut and broken coal slag is discharged outward through the channel between the borehole and the drill rod via the coal slag return water. However, the drill rod currently used rotates in one direction, which is not ideal for unidirectional coal slag crushing, and often results in large pieces of coal slag getting stuck and hindering the rotation of the drill rod. Summary of the Invention

[0003] To address the technical problem that the unidirectional rotation of the drill rod in current hydraulic drilling construction technology does not achieve ideal results in crushing coal slag, this invention proposes a synchronous multidirectional hydraulic drilling device and method.

[0004] The present invention achieves the above objectives through the following technical solutions:

[0005] This invention proposes a synchronous multi-directional hydraulic perforation device, comprising several drill rods, adjacent drill rods being connected in sequence by connectors, a nozzle being provided at the end of the outermost drill rod, and the drill rod being connected to the connectors; a rotating component is provided inside the drill rod, which is used to drive the drill rod to rotate relative to the connectors under the impact of high-pressure water inside the drill rod.

[0006] Preferably, the connector includes a first connector, a connecting sleeve, and a second connector. The first connector and the second connector are movably nested at both ends of the connecting sleeve. The first connector and the second connector are respectively connected to the connecting sleeve. The first connector and the second connector are respectively threadedly connected to the adjacent drill rod and are respectively connected to the adjacent drill rod.

[0007] Preferably, both the first connector and the second connector are provided with external threads. The external threads on the first connector and the second connector respectively cooperate with the rotating parts in the adjacent drill rods so that the rotating parts in the adjacent drill rods respectively drive the drill rods to rotate in the direction of locking the first connector and the second connector.

[0008] Preferably, the rotation directions of adjacent drill rods are in the same or opposite directions.

[0009] Preferably, the rotating component includes a swirl plate, and each drill rod is fixedly provided with a swirl plate. The swirl direction of the swirl plate is the direction that drives the drill rod to rotate and the direction that locks the connecting member. The swirl directions of the swirl plates in adjacent drill rods are in the same direction or opposite directions.

[0010] Preferably, the threads of the first connector and the second connector connected to both ends of the drill pipe are in the same direction.

[0011] Preferably, the nozzle is threadedly connected to the outermost drill rod, the nozzle is connected to the drill rod, and the nozzle is provided with spray holes.

[0012] Preferably, the nozzle is threadedly connected to the drill rod via the connector, and a plurality of spray holes are evenly provided along the circumference of the nozzle. A rotating component is provided inside the nozzle so that the rotating component can drive the nozzle to rotate relative to the connector under the impact of high-pressure water inside the nozzle.

[0013] This invention also proposes a method for operating a synchronous multi-directional hydraulic punching device, comprising the following steps:

[0014] S1. Unidirectional rotary punching: Several sections of drill rod are locked in the same direction with the corresponding connecting parts. High-pressure water is introduced into the drill rod. The high-pressure water impacts the rotating parts inside the drill rod. Under the impact of the high-pressure water, the rotating parts drive the drill rod to rotate synchronously in the direction of locking with the connecting parts.

[0015] S2. Multi-directional rotary punching: Several sections of drill rod are locked in different directions with their corresponding connectors. High-pressure water is introduced into the drill rod to impact the vortex plate. The vortex plate drives the drill rod to rotate synchronously in the direction of locking with the connector.

[0016] S3. Synchronous punching of nozzle: The nozzle is threadedly connected to the drill rod. The rotating part inside the drill rod drives the drill rod to rotate under the action of high pressure water. The drill rod drives the nozzle to rotate synchronously in the direction of locking with the drill rod.

[0017] S4. Sprayer head self-rotating punching: The sprayer head is connected to the drill rod through a connector. At the same time, a rotating component is installed inside the sprayer head. After high-pressure water is introduced into the sprayer head, the high-pressure water impacts the rotating component. The rotating component drives the sprayer head to rotate relative to the connector and in the direction of locking with the connector. At the same time, the high-pressure water is sprayed outward through the spray holes set in the circumference of the sprayer head, forming a rotating high-pressure jet water flow.

[0018] Preferably, the multi-directional rotary punching in step S2 includes different locking directions between adjacent drill rods and connecting parts.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. In this invention, the multi-section drill rod can rotate in multiple directions, which can repeatedly crush the coal slag in the coal slag water returned from the borehole, resulting in better crushing effect and reducing the occurrence of drill rod jamming.

[0021] 2. In this invention, the multi-section drill rod is connected by a threaded connector, which enables quick assembly and disassembly of the drill rod and can meet the equipment requirements for different punching distances.

[0022] 3. In this invention, the nozzle and the drill rod are connected by threads, and the drill rod drives the nozzle to rotate synchronously and lock, which can achieve efficient and stable rotation of the nozzle and avoid the drill falling off.

[0023] 4. In this invention, the nozzle is threadedly connected to the drill rod via a connector, and a rotating component is installed inside the nozzle. This allows the nozzle to rotate synchronously relative to the connector under the drive of the rotating component, thereby forming a rotating high-pressure jet water flow. At the same time, the relatively rotating nozzle and the drill rod cooperate with each other, and the direction of movement of the coal slag broken by the high-pressure jet water flow is opposite to the rotation direction of the drill rod. This allows the drill rod to efficiently break the coal slag, improving the coal slag crushing effect. Attached Figure Description

[0032] Example 1

[0033] The following is in conjunction with the appendix Figure 1-5 The technical solution of the present invention will be further explained below:

[0034] like Figures 1-5 As shown, the present invention discloses a synchronous multi-directional hydraulic punching device, comprising several drill rods 1, adjacent drill rods 1 being connected in sequence by connectors 3, a nozzle 4 being provided at the end of the outermost drill rod 1, and the drill rod 1 being connected to the connectors 3; a rotating component is provided inside the drill rod 1, which is used to drive the drill rod 1 to rotate relative to the connectors under the impact of high-pressure water inside the drill rod 1. In other words, multiple drill rods 1 are connected sequentially into a whole by connectors. The drill rod 1 at the first end is connected to the drilling rig, and the drill rod 1 at the last end is connected to the nozzle 4. The multiple drill rods 1 and the connectors are interconnected and can rotate. Rotating components are arranged inside each drill rod 1. Using the power generated by the high-pressure water impact, the rotating components drive the drill rod to rotate relative to the connectors 3. The entire drill rod can achieve synchronous rotation in the same direction, synchronous multi-directional rotation, alternating rotation, or the front half rotating in opposite directions to the rear half. Through the multi-directional rotation of the multiple drill rods, the coal slag in the coal slag water returned from the borehole can be repeatedly crushed in multiple directions, resulting in better crushing effect and reducing the occurrence of drill rod jamming.

[0035] Specifically, the connector 3 includes a first connector 31, a connecting sleeve 33, and a second connector 32. The first connector 31 and the second connector 32 are respectively movably nested at both ends of the connecting sleeve 33. The first connector 31 and the second connector 32 are respectively connected to the connecting sleeve 33. The first connector 31 and the second connector 32 are respectively threadedly connected to the adjacent drill rod 1, and the first connector 31 and the second connector 32 are respectively connected to the adjacent drill rod 1. In other words, the first connector 31 and the second connector 32 are respectively movably disposed within the connecting sleeve 33. The first connector 31 and the second connector 32 are interconnected with the connecting sleeve 33. At the same time, a limiting step is provided inside the connecting sleeve 33 to limit the stable movement of the first connector 31 and the second connector 32 within the connecting sleeve 33, while preventing the first connector 31 and the second connector 32 from disengaging from the connecting sleeve 33. External threads are provided on the first connector 31 and the second connector 32 respectively. The first connector 31 and the second connector 32 are threadedly connected to the adjacent drill rod 1. The drill rod 1 rotates rapidly in the direction of locking with the first connector 31 or the second connector 32 under the drive of the rotating component, preventing the drill rod 1 from disengaging from the connecting component 3. At the same time, the drill rod 1 can rotate relative to the connecting sleeve 33 to achieve stable delivery of high-pressure water.

[0036] Specifically, both the first connector 31 and the second connector 32 are provided with external threads. The external threads on the first connector 31 and the second connector 32 respectively cooperate with the rotating parts in the adjacent drill rods 1, so that the rotating parts in the adjacent drill rods 1 respectively drive the drill rods 1 to rotate in the direction of locking the first connector 31 and the second connector 32. In other words, external threads are provided on the first connector 31 and the second connector 32, and internal threads are provided inside the drill rod. The first connector 31 and the second connector 32 are threadedly connected to the adjacent drill rod 1. After high-pressure water is introduced into the drill rod 1, it impacts the rotating component, causing the rotating component to generate rotational kinetic energy. The rotating component drives the drill rod 1 to rotate in the direction of locking with the first connector 31 or the second connector 32. The internal thread on the drill rod 1 meshes with the external thread on the first connector 31 or the second connector 32. At the same time, the drill rod 1 and the first connector 31 or the second connector 32 form an integral unit that rotates rapidly relative to the connecting sleeve 33. This can prevent the drill rod 1 from separating from the connecting component and ensure the stability of high-pressure water transportation while the drill rod is crushing coal slag.

[0037] Optionally, the rotation directions of adjacent drill rods 1 can be in the same direction or in opposite directions. That is, in the integral multi-segment drill rod 1, two adjacent drill rods 1 can be configured to rotate in the same direction or in opposite directions. The rotation direction between adjacent drill rods 1 can be changed by adjusting the external thread setting direction of the corresponding first connector 31 and second connector 2 and the arrangement direction of the rotating parts.

[0038] Specifically, the rotating component will include a swirl plate 2, and each drill rod 1 will be fixedly provided with a swirl plate 2. The swirl direction of the swirl plate 2 is the direction that drives the drill rod 1 to rotate and the direction that locks with the connecting member 3. The swirl directions of the swirl plates 2 in adjacent drill rods 1 are the same or opposite. In other words, a swirl plate 2 is arranged inside the drill rod 1. The swirl plate 2 is an annular swirl plate composed of several swirl fins arranged at intervals. After high-pressure water is introduced into the drill rod 1, the high-pressure water impacts the swirl plate 2, causing the swirl plate 2 to generate rotational kinetic energy. The swirl plate 2 drives the drill rod to rotate in the direction of locking with the first connector 31 or the second connector 32. At the same time, in order to enable multiple sections of the drill rod 1 to rotate in the same or opposite directions, the swirl fins in the swirl plate 2 are arranged in the drill rod 1 in a clockwise or counterclockwise rotation direction. This allows the swirl direction of the swirl plate 2 inside the drill rod 1 to be different. Combined with the threads on the drill rod 1 and the first connector 31 or the second connector 32, adjacent drill rods 1 can rotate in the same or opposite directions.

[0039] Optionally, the threads of the first connector 31 and the second connector 32 connected to both ends of the drill rod 1 are in the same direction. That is, the threads of the first connector 31 or the second connector 32 in the two connectors 3 provided at both ends of the drill rod 1 are in the same direction, ensuring that the drill rod 1 does not detach from the two connectors 3 when the drill rod can rotate synchronously relative to the two connectors 3.

[0040] Optionally, the nozzle 4 is threadedly connected to the outermost drill rod 1, and the nozzle 4 is connected to the drill rod 1. The nozzle 4 is provided with a spray hole 41. That is, a common nozzle, i.e., a nozzle with an axial spray hole, is threadedly connected to the drill rod 1, and the nozzle 4 is connected to the drill rod 1. The rotating component inside the drill rod 1 drives the drill rod 1 to rotate under the impact of high-pressure water. The drill rod 1 drives the nozzle 4 to rotate synchronously in the direction of tightening the thread connecting to the drill rod 1, thereby ensuring the connection stability between the nozzle 4 and the drill rod 1 and preventing the nozzle 4 from falling off.

[0041] Optionally, the nozzle 4 is threadedly connected to the drill rod 1 via the connector 3, and a plurality of spray holes 41 are evenly opened along the circumference of the nozzle 4. A rotating component is provided inside the nozzle 41, which drives the nozzle 4 to rotate relative to the connector under the impact of the high-pressure water inside the nozzle 4. That is, the nozzle 4 is threadedly connected to the drill rod 1 via the connector 3, and a rotating component is provided inside the nozzle 4, so that the nozzle 4 rotates synchronously relative to the connector under the drive of the rotating component, thereby forming a rotating high-pressure jet water flow. At the same time, the relatively rotating nozzle 4 and the drill rod 1 cooperate with each other, and the direction of movement of the coal slag broken by the high-pressure jet water flow is opposite to the rotation direction of the drill rod 1, thereby efficiently breaking the coal slag through the drill rod and improving the coal slag crushing effect.

[0042] Example 2

[0043] This invention also discloses a method for operating a synchronous multi-directional hydraulic punching device, comprising the following steps:

[0044] S1. Unidirectional Rotary Punching: Several drill rod segments 1 are locked in the same direction with their corresponding connecting parts 3. High-pressure water is introduced into the drill rod 1, and the high-pressure water impacts the rotating parts inside the drill rod 1. Under the impact of the high-pressure water, the rotating parts drive the drill rod 1 to rotate synchronously in the direction of locking with the connecting parts 3. That is, the rotation direction of several drill rod segments 1 is set to rotate in the same direction. At this time, the arrangement direction of the swirl plates 2 in several segments is the same, with the swirl blades arranged in a clockwise direction. At the same time, the thread tightening direction of the connecting head in the drill rod 1 and the connecting part 3 is consistent with the swirl direction. At this time, under the impact of high-pressure water, the swirl plates drive the drill rod to rotate rapidly in the direction of locking with the connecting head, thereby realizing that multiple drill rod segments rotate in the same direction.

[0045] S2. Multi-directional Rotary Punching: Several drill rod segments 1 are locked in different directions with their corresponding connectors 3. High-pressure water is introduced into the drill rods to impact the vortex plates 2. The vortex plates 2 drive the drill rods 1 to rotate synchronously in the direction of locking with the connectors 3. That is, the rotation direction of the several drill rod segments 1 is set to rotate in two different directions. At this time, the arrangement direction of the several vortex plates 2 can be alternately opposite, that is, the vortex blades in each segment are arranged alternately in clockwise or counterclockwise. At the same time, the thread tightening direction of the connector in the drill rod 1 and the connector 3 is consistent with the vortex direction in the corresponding drill rod. After high-pressure water is introduced into the drill rod 1, the high-pressure water washes the vortex plates 2, causing the vortex plates 2 to generate rotational kinetic energy, which in turn drives the drill rod 1 to rotate in the direction of locking with the connector in the connector 3.

[0046] Optionally, the multi-directional rotary punching in step S2 includes different locking directions between adjacent drill rods 1 and connecting members 3. That is, the rotation directions of multiple drill rod segments 1 within the entire drill rod 1 can be arranged in an alternating pattern of rotating in opposite directions, thereby enabling the entire drill rod 1 to rotate in multiple directions. It should be noted that the entire drill rod 1 can also be arranged with the first half rotating in one direction and the second half rotating in the opposite direction. In other words, the entire drill rod simply has multiple drill rod segments rotating in two different directions.

[0047] S3. Synchronous Punching of Nozzle: Nozzle 4 is threadedly connected to drill rod 1. The rotating component inside drill rod 1 rotates under the action of high-pressure water, and drill rod 1 drives nozzle 4 to rotate synchronously in the direction of locking with drill rod 1. In other words, a common nozzle with axial nozzles is connected to drill rod 1. The rotating component inside drill rod 1 rotates under the action of high-pressure water, which in turn drives nozzle 4 to rotate. The rotation direction of the nozzle is consistent with the tightening direction of the drill rod connection thread.

[0048] S4. Sprayer Head Self-Rotating Punching: The sprayer head 4 is connected to the drill rod 1 via the connector 3. A rotating component is installed inside the sprayer head 4. When high-pressure water is introduced into the sprayer head 4, the high-pressure water impacts the rotating component, causing the sprayer head 4 to rotate relative to the connector and in the direction of locking with the connector 3. Simultaneously, the high-pressure water is ejected outward through the nozzles 41 arranged circumferentially on the sprayer head 4, forming a rotating high-pressure jet water flow. In other words, the sprayer head 4 is threadedly connected to the drill rod via the connector, and a rotating component is installed inside the sprayer head, allowing the sprayer head to rotate synchronously relative to the connector 3 under the drive of the rotating component. This forms a rotating high-pressure jet water flow. Simultaneously, the relatively rotating sprayer head 4 cooperates with the drill rod 1, and the direction of the coal slag crushed by the high-pressure jet water flow is opposite to the rotation direction of the drill rod, thus efficiently crushing the coal slag through the drill rod and improving the coal slag crushing effect.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
