[0026] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings of the specification.
[0027] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.
[0028] Secondly, the "one embodiment" or "embodiment" referred to herein means that a specific feature, structure, or characteristic described can be included in at least one implementation of the present application. The "in one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.
[0029] Embodiments
[0030] Reference Figures 1-6 For the embodiments of the present application, the embodiments provide a multi-directional adjustment underground pipeline guiding device, comprising,
[0031] The directional drilling machine body 100 comprises a machine body 110, a guide 120 arranged at the top of the machine body 110, a motor 130 adaptively installed at the top of the guide 120, a drill rod 140 arranged at the output end of the motor 130, and a caterpillar track 150 adaptively installed at the bottom of the machine body 110.
[0032] It should be noted that the machine body 110 is the basic support structure of the directional drilling machine body 100, which ensures the stability of the device during the working process. The guide 120 can guide the motor 130 and the drill rod 140 to move along the predetermined trajectory according to the pre-planned route using its positioning function, ensuring that the pipeline can accurately reach the target position. The motor 130 is used to provide power for the rotation and propulsion of the drill rod 140. The drill rod 140 can be driven by the motor 130 to drill underground and guide the drill bit to advance along the predetermined trajectory. The caterpillar track 150 can make the device move flexibly on different terrains, facilitating the equipment to reach the construction site and adjust the position, enhancing the mobility and adaptability of the device. Similar to the caterpillar track of a tank, it provides good passability for the equipment.
[0033] The dismounting mechanism 200 comprises a clamping assembly 210 for fixing the motor 130 and the drill rod 140, which is arranged between the motor 130 and the drill rod 140.
[0034] The limiting assembly 220 is arranged outside the clamping assembly 210 and is used to prevent the position of the clamping assembly 210 from deviating when the guide 120 rotates, causing the drill rod 140 to fall off.
[0035] The reset assembly 230 is arranged outside the limiting assembly 220 and is used to automatically control the clamping assembly 210 to release the limiting of the drill rod 140 when the limiting assembly 220 releases the limiting of the clamping assembly 210.
[0036] Specifically, the clamping assembly 210 comprises an inner threaded column 211 fixedly connected to the output of the motor 130 through a shaft coupling, an outer threaded column 212 threadedly connected to the inner surface of the inner threaded column 211, a bevel 213 formed in the inner wall of the outer threaded column 212, and clamping blocks 214 distributed in a circumferential array on the inner wall of the inner threaded column 211 and matched with the motor 130.
[0037] It should be noted that when the outer threaded column 212 rotates, it can move vertically along the inner wall of the inner threaded column 211, and the bevel 213 on the inner wall thereof can exert pressure on the inclined surface on the top of the clamping block 214. Since the inner side of the clamping block 214 has a high friction coefficient and the top inclined surface has a low friction coefficient, when the bevel 213 exerts pressure, the clamping block 214 shrinks and clamps the drill rod 140, thereby fixing the drill rod. When the drill rod is disassembled, the outer threaded column 212 is rotated in the opposite direction, the pressure of the bevel 213 on the clamping block 214 is reduced, thereby causing the clamping block 214 to loosen the drill rod 140.
[0038] Further, when the bevel 213 exerts pressure on the inclined surface on the top of the clamping block 214, it can drive the clamping block 214 to shrink and clamp the drill rod 140;
[0039] The inner side of the clamping block 214 has a high friction coefficient, and the top inclined surface has a low friction coefficient, which can effectively clamp the drill rod 140 while ensuring that the bevel 213 can smoothly exert pressure thereon.
[0040] Preferably, the limiting assembly 220 comprises a fixed sleeve 221 fixedly sleeved on the outer surface of the inner threaded column 211, connecting rods 222 distributed in a circumferential array on the inner surface of the inner threaded column 211, pawls 223 fixedly connected to the outer ends of the connecting rods 222, a ratchet wheel 224 sleeved on the outer surface of the outer threaded column 212 and matched with the pawls 223, a spring 225 sleeved on the outer side of the fixed sleeve 221, and a synchronization ring 226 fixedly connected to the outer end surface of the fixed sleeve 221.
[0041] It should be further noted that the spring 225 provides the pawls 223 with elastic restoring force, ensuring that they always have a tendency to cooperate with the ratchet wheel 224. When the ratchet wheel 224 moves towards the pawls 223, it can press the pawls 223, and through the cooperation of the pawls 223 and the ratchet wheel 224, the rotation direction of the outer threaded column 212 is limited, avoiding reverse rotation due to external force, causing the position of the clamping assembly 210 to deviate, and causing the drill rod 140 to fall off. Pulling the synchronization ring 226 can drive the connecting rods 222 and the pawls 223 to move synchronously, so that the pawls 223 move to a position where they are out of contact with the ratchet wheel 224, thereby releasing the limitation on the outer threaded column 212.
[0042] It should be noted that the outer surfaces of the connecting rod 222 and the pawl 223 are in sliding contact with the inner surface of the fixed sleeve 221, and the two ends of the spring 225 are fixedly connected with the outer surface of the pawl 223 and the inner surface of the fixed sleeve 221.
[0043] Further, the reset assembly 230 includes a rotating rod 231 fixedly installed on the outer surface of the fixed sleeve 221 through a bearing, a tooth column 232 fixedly sleeved on the outer surface of the rotating rod 231, a tooth disc 233 engaged with the outer surface of the tooth column 232, and a torsional spring 234 sleeved on the outside of the rotating rod 231.
[0044] It should be noted that when the externally threaded column 212 rotates, it can also drive the tooth disc 233 to rotate synchronously, so that the tooth disc 233 drives the tooth column 232 and the rotating rod 231 to rotate, and at the same time, the torsional spring 234 stores elastic potential energy. When the limiting assembly 220 releases the clamping of the clamping assembly 210, the pressure is released through the torsional spring 234, the rotating rod 231 is driven to rotate in the opposite direction, and the tooth column 232 and the tooth disc 233 are driven to rotate in the opposite direction, thereby driving the ratchet wheel 224 and the externally threaded column 212 to rotate in the opposite direction. The pawl 223 overcomes the elastic force of the spring 225 and disengages from the ratchet wheel 224. At this time, the clamping assembly 210 releases the clamping of the drill rod 140.
[0045] Specifically, the tooth disc 233 is fixedly sleeved on the outer surface of the ratchet wheel 224, and the two ends of the torsional spring 234 are fixedly connected with the outer surface of the fixed sleeve 221 and the outer end surface of the tooth column 232.
[0046] In use, the caterpillar 150 is controlled to move the directional drilling machine body 100 to the construction site and adjust to the appropriate position on different terrains due to its good mobility. Subsequently, the guide 120 is positioned according to the pre-planned pipeline laying route, the motor 130 and the drill rod 140 are guided to move along the predetermined trajectory, and the motor 130 is started. The power is transmitted to the clamping assembly 210 through the shaft coupling, so that the drill rod 140 is rotated and advanced to perform drilling work.
[0047] When the drill rod 140 is installed: the drill rod 140 is inserted into the internally threaded column 211, and the externally threaded column 212 is rotated to move vertically along the inner wall of the internally threaded column 211. The inclined port 213 of the inner wall exerts pressure on the top inclined surface of the clamping block 214. The clamping block 214 shrinks to clamp the drill rod 140 due to the high friction coefficient on the inner side and the low friction coefficient on the top inclined surface.
[0048] The spring 225 provides an elastic reset force for the pawl 223, so that it tends to engage with the ratchet wheel 224. When the outer threaded column 212 has a reverse rotation tendency, the ratchet wheel 224 presses the pawl 223, and the rotation of the outer threaded column 212 is limited by the cooperation of the two, preventing the position of the clamping assembly 210 from deviating and causing the drill rod 140 to fall off. At the same time, the toothed disc 233 rotates synchronously with the ratchet wheel 224, and drives the toothed column 232 and the rotating rod 231 to rotate, and the torsional spring 234 stores elastic potential energy.
[0049] When the limiting assembly 220 is released from the limiting of the clamping assembly 210: pulling the synchronous ring 226 drives the connecting rod 222 and the pawl 223 to move synchronously, so that the pawl 223 moves to a position away from the ratchet wheel 224 to release the limiting of the outer threaded column 212. The pressure of the torsional spring 234 is released to drive the rotating rod 231 to rotate in the opposite direction, and the toothed column 232 and the toothed disc 233 are driven to rotate in the opposite direction, thereby driving the ratchet wheel 224 and the outer threaded column 212 to rotate in the opposite direction. The pawl 223 overcomes the elastic force of the spring 225 and disengages from the ratchet wheel 224. At this time, the clamping assembly 210 releases the limiting of the drill rod 140, and the clamp block 214 releases the drill rod 140 to complete the disassembly.
[0050] In summary, through the cooperation of the components in the disassembly mechanism 200, not only can the installation and disassembly operation of the drill rod 140 be more convenient, but also can avoid the drill rod 140 from falling off during use, ensuring the safety of the construction process. To reduce the difficulty of replacing the drill rod 140 operation, and ensure that the drill rod 140 remains stable during use.
