Description

TECHNICAL FIELD

[0001] The present application relates to a drill rod lifting device, specifically a super deep hole curtain grouting drill rod lifting device, belonging to the technical field of hydraulic engineering. BACKGROUND

[0002] The super deep hole curtain generally refers to a drill hole with a depth exceeding 100 meters, which is used in dam foundation rock mass engineering geological conditions are poor, and the relative impermeable rock layer is buried at a depth exceeding 100 meters. During the super deep hole curtain grouting process, a geological drilling machine is used to drill a hole of a certain depth and diameter along the curtain axis direction and the vertical direction from the construction plane to the bottom line position of the anti-seepage curtain, and the underground rock core is taken out to determine the geological conditions, so that the drilled hole is used for curtain grouting, and the slurry is filled in the geological defects such as rock fissures, voids, and cavities, etc., to form a continuous and complete anti-seepage curtain between the construction plane and the anti-seepage curtain, so as to reduce the seepage pressure acting on the bottom of the dam or reduce the seepage flow, so that the dam foundation meets the engineering needs, ensures the stability and safety of the dam foundation, and the reservoir operates normally to achieve the benefits.

[0003] At present, the geological drilling machine usually uses a winch to lift the drill rod by means of a steel wire rope when drilling. The lifting precision is poor, and manual support is required. When the drill rod is added or removed, a drill rod wrench is usually used to limit the drill rod below to prevent the drill rod from falling and to increase the stability of the drill rod below.

[0004] A Chinese patent with the patent name of an automatic drill rod loading and unloading device and a drilling machine (publication number CN220539574U) discloses an automatic drill rod loading and unloading technology. However, although the device can realize the function of automatic loading and unloading of the drill rod, the overall structure is too large and relatively complex, the use cost is high, and the drilling main machine structure adopted is the same as that of the traditional drilling machine, which is fixed between the drill rod and the main machine by means of threads. This not only increases the wear of the drill rod threads during disassembly and assembly, but also directly affects the threads below, which may cause problems such as deformation, slipping, and sticking of the threads, reducing the service life of the drill rod.

[0005] A Chinese patent with the patent name of a power head overturning mechanism for a drilling machine (publication number CN118375382A) discloses a power head overturning technology for a drilling machine. However, although the mechanism has a relatively simple overall structure and a small size, it can quickly disassemble and assemble the drill rod by lifting and overturning the power head. However, the power head adopted is still the same as that of the traditional drilling machine, which still has the above-mentioned problems. Therefore, a super deep hole curtain grouting drill rod lifting device is proposed. SUMMARY

[0055] Among them, the drill pipe lifting mechanism 2 is used to drive the upper clamping pipe rotating assembly 3 to lift and lower, and can drive the whole assembly to rotate.

[0056] Among them, the pipe clamping and rotating assembly 3 uses the power of the dual drive mechanism 4 to clamp the rotating rod or drive the drill rod to rotate;

[0057] Among them, the drive switching mechanism 6 is used to lock the pipe clamping rotary assembly 3 and the dual drive mechanism 4 so that the power of the dual drive mechanism 4 can drive the pipe clamping rotary assembly 3 to rotate the drill rod, and to unlock the pipe clamping rotary assembly 3 and the dual drive mechanism 4 so that the power of the dual drive mechanism 4 can drive the pipe clamping rotary assembly 3 to clamp the rotating rod.

[0061] The output shafts of the two lifting drive motors 201 simultaneously drive the lifting worm gear 202 to rotate in the same direction. The rotating lifting worm gear 202 drives the lifting worm wheel 203 to move the first connecting plate 204 and the support slider 205. The moving first connecting plate 204 drives the clamp tube rotary assembly 3 to move up and down. The moving support slider 205 slides in the inner groove 206 to guide the moving lifting worm wheel 203.

[0062] Two lifting drive motors 201 drive the lifting worm gear 202 to rotate in the forward and reverse directions respectively, so that the two lifting worm gears 202 with opposite rotation directions can drive the lifting worm wheel 203 to rotate. The rotating lifting worm wheel 203 drives the clamping tube rotation assembly 3 to flip through the first connecting plate 204.

[0063] In one embodiment, the two tube clamping rotary assemblies 3 are an upper tube clamping rotary mechanism and a lower tube clamping rotary mechanism, respectively.

[0067] Among them, the rotating seat 301 of the upper clamping tube rotating mechanism is fixedly connected to the side of the first connecting plate 204 away from the lifting worm gear 203;

[0068] The rotating planar worm gear 303 uses its teeth to drive the L-shaped clamping plate 304 to slide along the guide groove 305 within the clamping seat 302, so that the moving L-shaped clamping plate 304 can clamp and fix the outer wall of the drill rod; the anti-slip part 82 is provided to increase the friction between the L-shaped clamping plate 304 and the outer wall of the drill rod.

[0069] In one embodiment, the dual drive mechanism 4 includes a dual drive motor 401, a drive worm 402 and a drive worm wheel 403.

The moving annular slide 602 drives the pin 603 to pass through the rotary seat 301 and insert into the clamp seat 302. Then, the moving pin 603 squeezes one end of the locking block 604 to completely push the locking block 604 out of the locking hole 607, so as to lock the clamp seat 302 and the rotary seat 301 and unlock the clamp seat 302 and the drive worm gear 403 at the same time. At the same time, the moving locking block 604 drives the spring 605 to be compressed.

[0075] In one embodiment, the auxiliary lifting assembly 7 consists of a geared motor 701, a gear chain linkage mechanism 702, two first guide rods 703, a central screw 704, and a second connecting plate 705.

[0076] The geared motor 701 is installed in the middle of the inner wall of the base 101. One end of the central screw 704 is rotatably connected to one side of the inner wall of the base 101. The inner wall of the second connecting plate 705 is threadedly connected to the outer wall of the central screw 704. Two first guide rods 703 are symmetrically fixedly connected to one side of the inner wall of the base 101. The outer wall of the first guide rod 703 is slidably connected to the inner wall of the second connecting plate 705. The gear chain linkage mechanism 702 is installed between the geared motor 701 and the central screw 704. The side of the second connecting plate 705 away from the base 101 is fixedly connected to the outer wall of a clamping tube rotating assembly 3.

One side of the second connecting plate 705 is fixedly connected to one side of the rotating seat 301 of the lower clamping tube rotating mechanism.

[0077] The toothed chain linkage mechanism 702 consists of a driving sprocket 721, a transmission chain 722, and a driven sprocket 723.

[0078] The drive sprocket 721 is fixedly connected to the output shaft of the geared motor 701, the inner sidewall of the driven sprocket 723 is fixedly connected to the bottom of the outer sidewall of the central screw 704, and the transmission chain 722 is meshed with the outer sidewalls of the drive sprocket 721 and the driven sprocket 723.

[0079] The output shaft of the geared motor 701 drives the drive sprocket 721 to rotate. The rotating drive sprocket 721 drives the driven sprocket 723 to rotate via the transmission chain 722. The rotating driven sprocket 723 drives the central screw 704 to rotate. The rotating central screw 704 drives the second connecting plate 705 to move up and down along the first guide rod 703 via the thread, so that the moving second connecting plate 705 can drive the entire lower clamping tube rotation mechanism to move up and down.

[0080] In operation, the invention works as follows: First, the device is installed in the designated position according to actual needs. When the drill rod needs to be lifted and fed, the output shafts of the two lifting drive motors 201 simultaneously drive the lifting worm gear 202 to rotate in the same direction. The rotating lifting worm gear 202 drives the lifting worm wheel 203 to move the first connecting plate 204 and the support slider 205. The moving first connecting plate 204 drives the rotating seat 301 of the upper clamping tube rotating mechanism to move. The moving support slider 205 slides in the inner groove 206 to guide the moving lifting worm wheel 203, thereby lowering the upper clamping tube rotating mechanism to the designated height. Then, the two lifting drive motors 201 drive the lifting worm gear 202 to rotate in the forward and reverse directions respectively, so that the two lifting worm gears 202 with opposite rotation directions drive the lifting worm wheel 203 to rotate. The rotating lifting worm wheel 203 drives the upper clamping tube rotating mechanism to flip through the first connecting plate 204, so that the mounting hole on it faces the side of the device, so that the drill rod can be inserted laterally into the upper clamping tube rotating mechanism from the side of the device.

[0081] When the drill pipe needs to be clamped and fixed in the upper tube clamping rotary mechanism, the piston rod of the first hydraulic cylinder 601 pushes the annular slide 602 to move. The moving annular slide 602 drives the pin 603 to pass through the rotary seat 301 and insert into the tube clamping seat 302. Then, the moving pin 603 squeezes one end of the locking block 604 so that the locking block 604 is completely pushed out from the locking hole 607, locking the tube clamping seat 302 and the rotary seat 301 while unlocking the tube clamping seat 302 and the drive worm gear 403. At the same time, the moving locking block 604 drives the spring 605 to be compressed. Then, the output shaft of the dual drive motor 401 drives the drive worm 402 to rotate. The rotating drive worm 402 drives the drive worm wheel 403 to rotate using its teeth. The rotating drive worm wheel 403 drives the planar worm disk 303 to move. The moving planar worm disk 303 drives the L-shaped clamping plate 304 to slide along the guide groove 305 in the clamping seat 302 using its teeth, so as to clamp and fix the outer wall of the drill rod using the moving L-shaped clamping plate 304. Then, the piston rod of the first hydraulic cylinder 601 drives the annular slide 602 to reset. The reset annular slide 602 drives the pin 603 to slide out from the locking hole 607. At the same time, the compressed spring 605 pushes the locking block 604 through the drive worm wheel 403 and inserts it into the locking hole 607, so as to unlock the rotary seat 301 and the clamping seat 302 and relock the drive worm wheel 403 and the clamping seat 302.

[0082] After the drill rod is clamped and fixed, the upper clamping tube rotation mechanism is driven to rise as a whole by the drill rod lifting mechanism 2 in order to lift and feed the drill rod. When the upper clamping tube rotation mechanism rises to the specified height, the upper clamping tube rotation mechanism is driven to flip by the drill rod lifting mechanism 2 in order to reset the upper clamping tube rotation mechanism and place the drill rod it clamps between the two clamping tube rotation components 3.

[0083] When it is necessary to connect the drill rod lifted by the upper clamping tube rotary mechanism with the drill rod held in the lower clamping tube rotary mechanism, the drill rod lifting mechanism 2 drives the upper clamping tube rotary mechanism to move the drill rod downward so as to connect the two drill rods. Then, the dual drive motor 401 on the upper clamping tube rotary mechanism drives the drive worm 402 to rotate. The rotating drive worm 402 drives the planar worm disk 303 and the clamping tube seat 302 to rotate simultaneously through the drive worm wheel 403. The rotating clamping tube seat 302 drives the clamped drill rod to rotate through the L-shaped clamping tube plate 304 so as to connect the two drill rods with threads.

[0084] When drilling operations are required using the drill rod after connection, the drill rod lifting mechanism 2 drives the upper clamping and rotating mechanism to move downwards, and the double drive mechanism 4 drives the upper clamping and rotating mechanism to rotate the drill rod, so that drilling operations can be performed using the rotating drill rod. When the geological conditions are hard and the drilling is restricted, the lower clamping and rotating mechanism can be driven by the double drive mechanism 4 on the lower clamping and rotating mechanism to perform secondary clamping of the drill rod, and the double drive mechanism 4 drives the clamping and rotating mechanism to assist the upper clamping and rotating mechanism in rotating the drill rod. Then, the output shaft of the reduction motor 701 drives the drive sprocket 721 to rotate, the rotating drive sprocket 721 drives the driven sprocket 723 to rotate via the transmission chain 722, and the rotating driven sprocket 723 drives the central screw 704 to rotate, and the rotating central screw 704 drives the threaded... The second connecting plate 705 is driven to move downward along the first guide rod 703, so as to drive the lower clamping pipe rotation mechanism to cooperate with the upper clamping pipe rotation mechanism to drive the drill rod to rotate and drill. When the lower clamping pipe rotation mechanism moves to its limit, the lower clamping pipe rotation mechanism can be driven by the dual drive mechanism 4 to release the clamping of the drill rod, and the drive sprocket 721 is driven to rotate in the opposite direction by the reduction motor 701, so as to cooperate with the transmission chain 722, the driven sprocket 723 and the central screw 704 to drive the second connecting plate 705 to move in the opposite direction, so as to reset the lower clamping pipe rotation mechanism.

[0085] When it is necessary to lift the drill pipe underground, the lower clamping pipe rotation mechanism is driven to the lowest position by the auxiliary lifting component 7. Then, the lower clamping pipe rotation mechanism is driven by the dual drive mechanism 4 to clamp the drill pipe. Then, the upper clamping pipe rotation mechanism and the lower clamping pipe rotation mechanism are driven to move upward by the drill pipe lifting mechanism 2 and the auxiliary lifting component 7 to pull out the drill pipe that has been drilled underground. This can effectively reduce the damage to the tooth pattern between the lifting worm gear 202 and the lifting worm wheel 203 caused by the large initial resistance when the drill pipe is initially lifted.

[0086] Example 2

[0087] like Figures 1-11 As shown, this embodiment of the invention provides an ultra-deep hole curtain grouting drill rod lifting device, including a base frame assembly 1 and a drill rod lifting mechanism 2. The base frame assembly 1 includes a base 101, a lifting bracket 102 and two side support rods 103.

[0088] The lifting bracket 102 is fixedly connected to the middle of the upper surface of the base 101. Two side support rods 103 are symmetrically installed between the base 101 and the lifting bracket 102. The drill pipe lifting mechanism 2 is installed on one side of the lifting bracket 102. Two vertically distributed pipe clamping rotary assemblies 3 are provided on one side of the lifting bracket 102. A dual drive mechanism 4 is installed on one side of each of the two pipe clamping rotary assemblies 3. A drive switching mechanism 6 is installed inside each of the two pipe clamping rotary assemblies 3. An auxiliary lifting assembly 7 is installed between the base 101 and a pipe clamping rotary assembly 3.

[0089] Among them, the drill pipe lifting mechanism 2 is used to drive the upper clamping pipe rotating assembly 3 to lift and lower, and can drive the whole assembly to rotate.

[0090] Among them, the pipe clamping and rotating assembly 3 uses the power of the dual drive mechanism 4 to clamp the rotating rod or drive the drill rod to rotate;

[0091] Among them, the drive switching mechanism 6 is used to lock the pipe clamping rotary assembly 3 and the dual drive mechanism 4 so that the power of the dual drive mechanism 4 can drive the pipe clamping rotary assembly 3 to rotate the drill rod, and to unlock the pipe clamping rotary assembly 3 and the dual drive mechanism 4 so that the power of the dual drive mechanism 4 can drive the pipe clamping rotary assembly 3 to clamp the rotating rod.

[0092] Among them, the auxiliary lifting component 7 is used to drive the lower pipe clamping and rotating component 3 to lift and lower, and to assist the upper pipe clamping and rotating component 3 in driving the drill pipe.

[0093] In one embodiment, the auxiliary lifting assembly 7 consists of two lower support plates 771, two second hydraulic cylinders 772, a third connecting plate 773, and two second guide rods 774;

[0094] The third connecting plate 773 is fixedly connected to the outer wall of a tube clamping rotary assembly 3. The outer wall of the third connecting plate 773 is slidably connected to one side of the inner wall of the base 101. The two second guide rods 774 are symmetrically fixedly connected to one side of the inner wall of the base 101. The inner wall of the third connecting plate 773 is slidably connected to the outer wall of the two second guide rods 774. The two lower support plates 771 are symmetrically fixedly connected to the bottom of one side of the base 101. The two second hydraulic cylinders 772 are installed on the inner wall of the lower support plates 771. The piston rods of the two second hydraulic cylinders 772 are fixedly connected to the bottom of a tube clamping rotary assembly 3.

[0095] The third connecting plate 773 is provided to provide support for the bottom of the second hydraulic cylinder 772. The third connecting plate 773 is fixed to the rotary seat 301 of the lower clamping tube rotary mechanism so that the third connecting plate 773 can slide on one side of the base 101 when the rotary seat 301 moves. The second guide rod 774 is provided to guide the moving third connecting plate 773.

[0096] The difference from Embodiment 1 is that the piston rod of the second hydraulic cylinder 772 pushes the rotating seat 301 of the lower clamping tube rotating mechanism to move up and down, so as to use hydraulic power to drive the lower clamping tube rotating mechanism to lift and lower. Compared with Embodiment 1, it can provide greater power to the lower clamping tube rotating mechanism.

[0097] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
