Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically a drilling device for water conservancy construction. Background Technology

[0002] Drilling is a crucial step in water conservancy project construction, widely used in foundation reinforcement, anti-seepage wall construction, hydrogeological surveys, and other scenarios. By creating compliant holes at designated locations using drilling equipment, the necessary conditions are provided for subsequent grouting, component installation, and other operations, directly impacting the construction quality and structural stability of the water conservancy project.

[0003] According to the search, the authorized announcement number is CN221609902U, which discloses a drilling device for water conservancy construction. By setting a pin, when it is necessary to fix the device, it is first moved to a designated position, and then the auxiliary motor is started. The output end of the auxiliary motor drives the corresponding screw to rotate. The rotating screw, through the main pulley and main belt, drives another screw to rotate. The rotating screw drives the pin to move, so that the pin contacts the ground and inserts into the ground, thus fixing the device.

[0004] However, the aforementioned drilling devices can only achieve vertical drilling in actual use, and cannot drill at other angles, thus lacking the flexibility to adjust the drilling angle. In water conservancy projects, inclined drilling or multi-angle drilling operations are often required depending on the construction conditions. Fixed-angle drilling devices are difficult to adapt to these needs, requiring cumbersome auxiliary positioning or the replacement of specialized equipment to complete the work. This not only increases the complexity of the construction process and reduces construction efficiency, but also increases construction costs, failing to meet the diverse requirements of water conservancy drilling construction.

A worm gear is engaged with the outer surface of the transmission rod, and a worm wheel is connected to the worm gear. A pin is fixedly connected to the end of the connecting shaft away from the support frame plate, and a pointer is engaged with the outer surface of the pin.

[0011] Preferably, a limiting groove is formed on the outer peripheral surface of the pin, and an insertion hole adapted to the outer peripheral surface of the pin and the limiting groove is formed on the pointer, and the pin and the pointer are fastened together by screws.

[0012] Preferably, the output shaft of the hydraulic motor is fixedly connected to a drill pipe joint, the drill pipe joint is internally threaded with a drill rod, and the outer surface of the limiting baffle has two through holes for inserting a polished rod and one round hole for the drill rod to pass through.

[0013] Preferably, the bottom surface of the base plate is fixedly connected to two ground nails, and the bottom surface of the base plate is rotatably connected to two movable wheels. Two push handles are welded to both sides of the support vertical plate near the top.

[0014] Preferably, a rack is fixedly connected to the inner side of the support frame plate, a limiting tooth block is engaged in the tooth groove of the rack, two guide rods are threadedly connected to the outer surface of the limiting tooth block, a compression spring is sleeved on the outer circumference of the two guide rods, and a limiting plate is fixedly connected to the top of the guide rod.

[0015] Preferably, the outer surface of the base has a through-hole for sliding cooperation with the guide rod, and the outer surface of the base has a through-hole rectangular groove. Lugs are fixedly connected to both sides of the rectangular groove, and an L-shaped lever is rotatably connected between the two lugs. An eccentric wheel is fixedly connected to the outer surface of the L-shaped lever by bolts.

[0016] Compared with the prior art, this utility model provides a drilling device for hydraulic construction, which has the following beneficial effects:

[0017] 1. This utility model allows the transmission structure to rotate as a whole, including the support frame and drilling components, by turning the handwheel, thus achieving angle adjustment. During adjustment, the pointer and the angle scale lines visually indicate the current angle, helping workers to accurately control the adjustment range and ensure that the drilling angle meets construction requirements. This precise adjustment function can adapt to drilling needs of different slopes and orientations in water conservancy construction, effectively avoiding construction quality problems caused by angle deviations and improving the standardization and reliability of drilling operations.

[0018] 2. This utility model uses an L-shaped lever between the lugs to reverse the eccentric wheel, releasing it from contact with the limiting tooth block. The compressed spring automatically releases its elastic potential energy, pushing the limiting tooth block quickly away from the rack groove via the guide rod, thus automatically releasing the base limit. The entire unlocking process is smooth and effortless, allowing workers to quickly switch to the drilling feed state. After unlocking, the base can slide smoothly along the guide rod, ensuring the stability of the drilling feed and effectively improving overall work efficiency. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 A drilling device for hydraulic construction includes a base plate 1, a supporting vertical plate 2 fixedly connected to the top surface of the base plate 1, a drilling angle adjustment component 3 bolted to both sides of the supporting vertical plate 2, a bearing seat 4 bolted to the outer surface of the supporting vertical plate 2, a connecting shaft 5 rotatably connected inside the bearing seat 4, a supporting frame plate 6 fixedly connected to one end of the connecting shaft 5, two smooth rods 7 bolted to the inner side of the supporting frame plate 6, a base 8 slidably connected to the outer surface of the two smooth rods 7, a hydraulic motor 9 fixedly connected to the outer surface of the base 8, and a limit baffle 10 bolted to the outer periphery of the smooth rods 7.

[0027] The drilling angle adjustment component 3 includes an outer frame plate 31, with transmission rods 32 rotatably connected to both sides of the outer frame plate 31. A worm gear 33 is engaged with the outer surface of the transmission rod 32, and a worm wheel 34 is connected to the worm gear 33. A pin 35 is fixedly connected to the end of the connecting shaft 5 away from the support frame plate 6. A pointer 36 is engaged with the outer surface of the pin 35. An angle scale line 37 is engraved on the outer surface of the outer frame plate 31.

[0028] Specifically, the worm gear 34 is fixedly sleeved on the outer circumferential surface of the stepped shaft of the connecting shaft 5, one end of the pin 35 is fixedly connected to the stepped shaft of the connecting shaft 5, and one end of the transmission rod 32 is fixedly connected to the handwheel 38.

[0029] Specifically, a limiting groove is provided on the outer peripheral surface of the pin 35, and an insertion hole adapted to the outer peripheral surface of the pin 35 and the limiting groove is provided on the pointer 36. The pin 35 and the pointer 36 are fastened together by screws.

[0030] The advantage is that by rotating the handwheel 38 fixed to one end of the transmission rod 32, the operator can drive the transmission rod 32 to rotate synchronously. The worm gear 33, which is engaged with the outer surface of the transmission rod 32, will rotate accordingly. Since the worm gear 33 and the worm wheel 34 fixedly sleeved on the outer circumference of the stepped shaft of the connecting shaft 5 form a meshing transmission, the rotation of the worm gear 33 will drive the worm wheel 34 and the connecting shaft 5 to rotate around the shaft seat 4 together. The support frame plate 6 fixedly connected to one end of the connecting shaft 5 will change its tilt angle with the rotation of the connecting shaft 5, thereby driving the drilling-related components such as the smooth rod 7, the base 8, the hydraulic motor 9, and the drill rod 12 on the support frame plate 6 to adjust their angles synchronously. At the same time, the pin 35 fixed to the end of the connecting shaft 5 away from the support frame plate 6 will rotate with the connecting shaft 5. The pointer 36, which is fastened to the outer surface of the pin 35 by screws, will indicate the current angle according to the angle scale line 37 engraved on the outer surface of the outer frame plate 31, helping the operator to accurately control the adjustment range and ultimately achieve flexible and precise adjustment of the drilling angle.

[0031] Specifically, the output shaft of the hydraulic motor 9 is fixedly connected to a drill pipe joint 11, and the drill pipe joint 11 is internally threaded to connect to a drill rod 12. The outer surface of the limiting baffle 10 has two through holes for inserting the light rod 7 and a round hole for the drill rod 12 to pass through.

[0032] The advantages are that after the drilling angle is adjusted, the hydraulic motor 9 drives the drill pipe joint 11 to rotate, and the drill pipe joint 11 drives the drill rod 12 to rotate, aligning the drill rod 12 with the drilling point. After the base 8 is released from its restraint, the base 8 can be slowly slid on the outer surface of the smooth rod 7 by pushing the handle fixedly connected to the outer surface of the base 8. This allows the drill rod 12 to gradually penetrate into the soil at the water conservancy construction site while rotating at high speed, thus carrying out drilling operations. The maximum stroke of the drill rod 12 into the soil can be limited by setting the limit baffle 10, which facilitates timely replacement of the drill rod 12.

[0033] Specifically, two ground nails 13 are fixedly connected to the bottom surface of the base plate 1, and two movable wheels 14 are rotatably connected to the bottom surface of the base plate 1. Two push handles 15 are welded to the two sides of the supporting vertical plate 2 near the top.

[0034] The advantages are that the two push handles 15 welded to the top of both sides of the supporting vertical plate 2 provide workers with convenient gripping and force application points, making it easy to move the entire device by pushing and pulling; the two moving wheels 14 rotatably connected to the bottom surface of the base plate 1 convert the sliding friction between the device and the ground into rolling friction, greatly reducing the resistance during movement, allowing workers to easily push the device to move flexibly within the construction site with the help of the push handles 15, reducing the handling intensity. It is worth noting that when pushing the device, the supporting vertical plate 2 should be kept tilted to avoid the ground nails 13 contacting the ground; the two ground nails 13 fixedly connected to the bottom surface of the base plate 1 mainly serve to position and fix the device. When the supporting vertical plate 2 is erected vertically, the two ground nails 13 can penetrate into the soil, thus fixing the device and preventing displacement during subsequent drilling.

[0035] Specifically, a rack 16 is fixedly connected to the inner side of the support frame plate 6. A limiting tooth block 17 is engaged in the tooth groove of the rack 16. Two guide rods 18 are threadedly connected to the outer surface of the limiting tooth block 17. A compression spring 19 is sleeved on the outer circumference of the two guide rods 18. A limiting piece is fixedly connected to the top of the guide rod 18. One end of the compression spring 19 abuts against the limiting piece of the guide rod 18, and the other end of the compression spring 19 abuts against the base 8.

[0036] Specifically, a circular hole is provided through the outer surface of the base 8 to slide with the guide rod 18, and a rectangular groove is provided through the outer surface of the base 8. Ear blocks 20 are fixedly connected to both sides of the rectangular groove, and an L-shaped lever 21 is rotatably connected between the two ear blocks 20. An eccentric wheel 22 is fixedly connected to the outer surface of the L-shaped lever 21 by bolts.

[0037] The advantage is that, in the non-drilling state, the operator needs to move the L-shaped lever 21 rotatably connected between the two lugs 20, which drives the eccentric wheel 22 fixed to its outer surface by bolts to rotate synchronously. The rotating eccentric wheel 22 will directly abut against the limiting tooth block 17 through the rectangular groove opened on the outer surface of the base 8, pushing the limiting tooth block 17 to be tightly engaged in the tooth groove of the rack 16 fixed on the inner side of the support frame plate 6. At this time, the guide rod 18 threadedly connected to the limiting tooth block 17 will adjust its position synchronously with the movement of the limiting tooth block 17. The compression spring 19 sleeved on the outer periphery of the guide rod 18 is compressed and stored, thereby locking the base 8. Positioned on the guide rod 7, it prevents accidental sliding due to external force or its own weight, thus avoiding deviation of the drill rod 12 from the preset drilling point. When drilling feed is required, the L-shaped lever 21 is reversed, causing the eccentric wheel 22 to rotate synchronously, so that the eccentric wheel 22 no longer resists the limiting tooth block 17. At this time, the compressed spring 19 releases its elastic potential energy, which pushes the guide rod 18 to reset through the limiting plate at the top of the guide rod 18, thereby causing the limiting tooth block 17 to disengage from the tooth groove of the rack 16, releasing the limitation on the base 8. The operator can then push the base 8 to slide smoothly along the guide rod 7, ensuring stable and orderly operation.

[0038] In use, the operator first tilts the support plate 2 using the push handles 15 on both sides of the support plate 2, causing the ground nails 13 on the bottom surface of the base plate 1 to detach from the ground. The entire device is then pushed to the designated working position using the moving wheels 14 on the bottom surface of the base plate 1. Next, the support plate 2 is erected vertically, allowing the ground nails 13 to penetrate the soil and secure the device. Then, the handwheel 38 at one end of the transmission rod 32 is rotated, causing the transmission rod 32 and the worm gear 33 on its outer surface to rotate. Through the meshing transmission between the worm gear 33 and the worm wheel 34 on the outer circumference of the stepped shaft of the connecting shaft 5, the connecting shaft 5 and the support frame plate 6 at one end are driven to rotate and adjust the angle. Simultaneously, the adjustment range is precisely controlled according to the angle scale line 37 on the outer frame plate 31 corresponding to the pointer 36 on the outer surface of the pin 35. After the angle adjustment is completed, it is confirmed that the base 8 is in the locked state (the limit tooth block 17 engages with the rack 16 on the inner side of the support frame plate 6). The drill rod 12 is then driven through the drill... The drill pipe connector 11 is installed and fixed, and aligned with the drilling point. The hydraulic motor 9 is started to drive the drill pipe connector 11 and drill rod 12 to rotate. Then, the L-shaped lever 21 between the lugs 20 of the base 8 is moved in the opposite direction, which drives the eccentric wheel 22 to reverse and disengage from the limiting tooth block 17. The compressed spring 19 releases its elastic potential energy to push the guide rod 18 to reset, so that the limiting tooth block 17 disengages from the rack 16 and releases the base 8 from the limit. The worker pushes the base 8 to slide along the smooth rod 7, so that the drill rod 12 gradually penetrates into the soil while rotating, until it contacts the limiting baffle 10 and reaches the maximum stroke. After drilling is completed, the hydraulic motor 9 is turned off, and the L-shaped lever 21 is moved in the forward direction to relock the base 8. If the drill rod 12 needs to be replaced, the drill pipe connector 11 is disassembled. After the operation is completed, the support plate 2 is tilted to remove the ground nail 13 from the soil. The device is moved to the next position or storage point by pushing the handle 15 and moving wheel 14.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
