Description

Technical Field

[0001] This utility model belongs to the field of building construction equipment technology, specifically, it relates to a rapid drilling device for constructing drainage holes in spillways. Background Technology

[0002] As a key flood discharge facility in a water conservancy project, the construction quality of the internal drainage system of the spillway directly affects the safe and stable operation of the project. As a core component of the drainage system, the drainage holes need to be laid out in different areas and at different inclination angles on the inner wall of the spillway to achieve rapid drainage of seepage water and avoid long-term erosion of the tunnel structure, which would lead to damage and reduced strength. Therefore, the accuracy, efficiency, and adaptability to complex working conditions of the drilling operation are the core requirements for ensuring construction quality and progress during the construction of drainage holes.

[0003] Currently, the drilling equipment used for constructing drainage holes in spillways is mostly traditional handheld drilling machines or fixed-support drilling devices. These devices have many technical shortcomings in actual construction and are difficult to meet the needs of the complex construction environment of spillways. Firstly, the angle adjustment is not flexible enough and the adaptability is poor. Traditional drilling equipment is mostly designed with a fixed angle or can only achieve small-range angle fine adjustment. It cannot adapt to the construction needs of drainage holes with multiple directions and large angles of inclination on the inner wall of the spillway. When drilling is required in the tunnel wall area with different inclination angles, the overall position of the equipment needs to be moved repeatedly and the support structure needs to be rebuilt. Not only is the operation cumbersome, but it is also easy for the drilling position and angle to not meet the design requirements due to the deviation of the equipment placement, which in turn affects the drainage effect. Secondly, the angle positioning stability is poor, and the drilling accuracy is difficult to guarantee. Existing adjustable angle drilling equipment mostly uses mechanical bolt locking to lock the angle. Uneven force is prone to occur during the locking process, resulting in slight deviation after positioning. Moreover, when the drilling machine is operating at high frequency, the bolts are prone to loosening, which further aggravates the angle deviation, causing the verticality and positional accuracy of the drainage hole to exceed the standard. Subsequent repair work is required, which increases the construction cost and construction period. Third, the lack of vibration buffering leads to high equipment wear and tear and low operational safety. Drilling machines generate high-frequency vibrations during operation. Traditional equipment lacks an effective buffer structure, and the vibration is directly transmitted to the main body of the equipment and the operator's hands. On the one hand, it can easily lead to operator fatigue and increase the risk of operational errors. On the other hand, long-term vibration will accelerate the wear of equipment parts, reduce the service life of the equipment, and may even cause the equipment to go out of control due to vibration, resulting in safety accidents. To address the aforementioned issues, this application proposes a rapid drilling device for constructing drainage holes in spillways. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a rapid drilling device for the construction of drainage holes in spillways, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rapid drilling device for constructing drainage holes in spillways includes a base plate. Two support plates are fixedly installed on the top of the base plate. The two support plates are rotatably connected to the same arc-shaped positioning ring. A spherical mounting box is rolled on the inner wall of the arc-shaped positioning ring. An mounting cylinder is fixedly installed on the inner wall of the spherical mounting box. A handle is installed on the top of the mounting cylinder. The bottom of the mounting cylinder is open. An mounting plate is slidably connected to the inner wall of the mounting cylinder. A drilling machine is installed at the bottom of the mounting plate. A power supply box is installed on the top of the base plate. A handle is installed on the top of the power supply box. An adaptive angle fixing mechanism includes a high-pressure air pump, which is installed on the top of the mounting cylinder and cooperates with the mounting plate. The mounting cylinder is connected to the spherical mounting box, and multiple push rods are slidably connected on the spherical mounting box. The push rods cooperate with the arc-shaped positioning ring to push.

[0006] Preferably, the adaptive angle fixing mechanism further includes multiple fixing cylinders, which are fixedly installed on the outer inner wall of the spherical mounting box and are interconnected with the spherical mounting box. A piston plate is slidably connected to the inner wall of the fixing cylinder, and the piston plate is fixedly connected to the corresponding push rod.

[0007] Preferably, a conical locking block is fixedly installed at one end of the top rod, and multiple slots are provided on the inner wall of the arc-shaped positioning ring, with the conical locking block engaging with the slots.

[0008] Preferably, positioning shafts are fixedly installed on both sides of the arc-shaped positioning ring, and the positioning shafts are rotatably connected to the corresponding support plates. A fixed box is fixedly installed on one of the two support plates, and a drive shaft is rotatably connected to the fixed box. The drive shaft is drively connected to the corresponding positioning shaft.

[0009] Preferably, a worm gear is fixedly mounted on the drive shaft, and a worm wheel is fixedly mounted on one end of the positioning shaft. The worm gear and the worm wheel mesh with each other, and both the worm gear and the worm wheel are located inside the fixed box.

[0010] Preferably, retaining rings are fixedly installed at both the top and bottom of the spherical mounting box, and the retaining rings are pushed and engaged with the arc-shaped positioning ring.

[0011] In summary, the technical effects and advantages of this utility model are as follows: By combining the arc-shaped positioning ring with the spherical mounting box, the drilling machine can be freely adjusted in multiple directions to meet the drilling needs of drainage holes with different inclination angles and orientations on the inner wall of the spillway. At the same time, the worm gear transmission mechanism drives the arc-shaped positioning ring to rotate, further expanding the angle adjustment range. This eliminates the need to repeatedly move the entire device, greatly improving its adaptability to the special construction environment of the spillway.

[0012] Driven by a high-pressure air pump, the linkage clamping structure uses high-pressure gas to push the piston plate, which in turn moves the top rod and the conical clamping block to precisely engage with the groove on the inner wall of the arc-shaped positioning ring. This allows for quick locking and fixing of the drilling angle. Compared to traditional mechanical locking methods, this pneumatic positioning structure provides uniform force and prevents loosening or displacement after positioning. This effectively ensures the verticality and positional accuracy of the drainage hole, preventing drainage hole failure due to angular deviation.

[0013] The gas injected by the high-pressure air pump not only completes the angle positioning, but also acts on the mounting plate inside the mounting cylinder, providing flexible buffer for the drilling machine's downward drilling action; when the drilling machine generates high-frequency vibration, the gas buffer structure can absorb most of the vibration impact force, reduce the damage of vibration to the device components and the drilling machine, reduce the probability of equipment failure, and extend the overall service life of the device.

The adaptive angle fixing mechanism 6 includes a high-pressure air pump 66, which is installed on the top of the mounting cylinder 4 and cooperates with the mounting plate 7. The mounting cylinder 4 is connected to the spherical mounting box 5. Multiple push rods 63 are slidably connected on the spherical mounting box 5, and the push rods 63 cooperate with the arc-shaped positioning ring 3 to push.

[0018] Reference Figure 4 and Figure 7 The adaptive angle fixing mechanism 6 also includes multiple fixing cylinders 61, which are fixedly installed on the outer inner wall of the spherical mounting box 5 and are interconnected with the spherical mounting box 5. A piston plate 62 is slidably connected to the inner wall of the fixing cylinder 61, and the piston plate 62 is fixedly connected to the corresponding push rod 63. A conical block 64 is fixedly installed at one end of the push rod 63. Multiple slots 65 are opened on the inner wall of the arc-shaped positioning ring 3. The conical block 64 is engaged with the slot 65. The high-pressure gas in the spherical mounting box 5 is introduced into the multiple fixing cylinders 61 through the interconnection with the fixing cylinders 61, and pushes the piston plate 62 to move. The piston plate 62 pushes the push rod 63 to move, driving the conical block 64 to push into the slot 65, thereby forming a locking and positioning.

[0019] Reference Figure 6Positioning shafts 12 are fixedly installed on both sides of the arc-shaped positioning ring 3. The positioning shafts 12 are rotatably connected to the corresponding support plates 2. A fixed box 16 is fixedly installed on one of the support plates 2.

At the same time, the gas in the mounting cylinder 4 pushes... The mounting plate 7 moves downwards, driving the drilling machine 8 to move, allowing the drilling machine 8 to drill at the target location. At the same time, the gas in the mounting cylinder 4 can buffer the drilling machine 8 during drilling, preventing high-speed vibration from affecting the operation of the device. When drilling is required in the wall, the drive shaft 13 rotates. The rotating drive shaft 13, through the meshing of the worm gear 14 and the worm wheel 15, can drive the positioning shaft 12 to change angle, which in turn can drive the arc-shaped positioning ring 3 to change angle.
