Description

Technical Field

[0001] This utility model belongs to the field of deep hole blasting technology, and specifically relates to a device for clearing and preventing jamming of deep hole blasting blasting boreholes. Background Technology

[0002] The deep hole blasting borehole clearing and anti-jamming rod device is a special tool designed to solve the problems of borehole blockage, collapse, or foreign object obstruction during deep hole drilling. Its core objective is to ensure the smooth progress of drilling operations and reduce safety risks.

[0003] Currently, Chinese utility model patent CN219284187U discloses an open-pit deep-hole blasting borehole detection device. It achieves effective detection of borehole depth and diameter through a servo motor, measuring rope and replaceable probe structure, and can clear minor blockages. It has good performance under normal working conditions.

[0004] The aforementioned device poses significant safety hazards when dealing with sudden geological changes. When the probe encounters extreme conditions such as rock bursts, large water inrushes, foreign object jamming, or borehole wall collapse in the borehole, the measuring rope and transmission system are subjected to huge loads instantly. If the motor continues to apply tension or the operator forcibly drags it at this time, it is very easy to cause the transmission shaft to twist, the motor to burn out, or even the measuring rope to break. Furthermore, the broken rod fragments will remain inside the hole, forming new obstacles and significantly increasing the difficulty and cost of subsequent processing; At the same time, sudden geological changes can cause equipment to rebound violently or the measuring rope to suddenly come loose, posing a serious threat to the personal safety of on-site operators and posing a risk of major accidents such as falls and impacts. The existing device lacks an emergency release mechanism that can separate in a timely and reliable manner under overload conditions, and cannot achieve controlled separation while ensuring the safety of personnel and core equipment. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a device for clearing and preventing jamming of deep-hole blasting blasting boreholes.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a deep-hole blasting borehole clearing and anti-jamming device, comprising a drill body module, a fixed end head fixed to one end of the drill body module, a fixed circumferential groove symmetrically formed on the circumference of the fixed end head, an emergency module at one end of the drill body module, the emergency module comprising an emergency base plate and multiple T-shaped clamps, the multiple T-shaped clamps being relatively distributed, auxiliary connecting rods fixed on both sides of one T-shaped clamp, a force-applying plate fixed to the end of the auxiliary connecting rod away from the T-shaped clamp, another T-shaped clamp between one T-shaped clamp and the force-applying plate, the inner wall of the T-shaped clamp near the force-applying plate being slidably connected to the circumferential surface of the auxiliary connecting rod, and a return spring sleeved on the circumferential surface of the auxiliary connecting rod between the multiple T-shaped clamps; the emergency module further comprises multiple protruding wheels, the multiple protruding wheels being rotatably connected to the inner wall of the emergency base plate, the multiple protruding wheels being disposed between the force-applying plate and the T-shaped clamp near the force-applying plate; the multiple protruding wheels being driven by a drive module.

[0007] Preferably, the drive module includes a drive base plate and a shaft. One end of the shaft is fixed to one end of the multi-protruding wheel. A fixing ring is keyed to the surface of the shaft. A fixing slide is fixed to the circumference of the fixing ring. A moving rod is slidably connected to the inner wall of the fixing slide. A drive cylinder is rotatably connected to one end of the moving rod. One side of the drive cylinder is fixed to the inner wall of the drive base plate.

[0008] Preferably, a limiting rod is fixed to one end of the driving cylinder near the moving rod, and a limiting groove is formed on the inner wall of the driving base plate. The limiting groove is arranged parallel to the driving cylinder, and the end of the limiting rod away from the moving rod is slidably connected to the inner wall of the limiting groove.

[0009] Preferably, the inner wall of the fixed slide is provided with a protrusion, and the two sides of the moving rod are provided with limiting grooves, and the inner wall of the limiting groove is slidably connected to the surface of the protrusion of the fixed slide.

[0010] Preferably, auxiliary arc grooves are provided on the opposite sides of the force-applying plate and the T-shaped clamp near the force-applying plate.

[0011] Preferably, both sides of the inner wall of the auxiliary arc groove are provided with arc edges.

[0012] Preferably, each of the T-shaped clamps has a V-shaped groove on its opposite side that matches the fixing circumferential groove.

[0013] Preferably, each pair of opposite end faces of the drill module, the emergency base plate of the emergency module, and the drive base plate of the drive module is provided with a positioning post and a corresponding positioning hole.

[0014] In summary, this utility model has the following beneficial effects: 1. This utility model uses multiple T-shaped clamps of the emergency module to clamp the fixed end, and further improves the clamping stability of the T-shaped clamps through the fixed peripheral groove, so that the drill module can maintain stable fixation with the emergency module during operation. When a sudden geological change occurs, the operator can control the rotation of the multiple protruding wheel to release the contact between the multiple protruding wheel and the force plate and T-shaped clamps. Under the release of the elastic potential energy of the return spring, the multiple T-shaped clamps quickly move away from each other at both ends, so that the drill module and the emergency module can be quickly separated. Thus, it has a timely and reliable emergency release mechanism for separation during sudden geological changes, so that the drill module can be separated from the main equipment, thereby better protecting the safety of equipment and personnel. 2. This utility model can quickly drive the shaft to rotate through the drive cylinder of the drive module, thereby enabling the multi-protruding wheel to rotate quickly. Furthermore, by driving the moving rod through the drive cylinder, the lever arm distance can be greatly increased, reducing the required torque. This allows for a reduction in the size of the drive cylinder. Moreover, the response speed of the drive cylinder is faster than that of the motor, making it more suitable for emergency use and improving the equipment's performance. 3. This utility model provides an auxiliary arc groove near the force-applying plate and T-shaped clamp when they contact the multi-protruding wheel, thus preventing slippage between the multi-protruding wheel and the force-applying plate and T-shaped clamp during underground operations due to strong vibrations. This improves the fixing effect. Furthermore, both sides of the auxiliary arc groove are curved edges, which provide guidance when in contact with the groove. This ensures that the T-shaped clamp and force-applying plate are stably pushed towards both ends when the shaft rotates to drive the multi-protruding wheel, preventing wear caused by hard contact and extending the equipment's service life.

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings: Example

[0019] refer to Figures 1-7 A deep-hole blasting borehole clearing and anti-jamming device includes a drill body module 1. A fixed end 101 is fixed to one end of the drill body module 1. A fixed circumferential groove 201 is symmetrically formed on the circumference of the fixed end 101. An emergency module 2 is provided at one end of the drill body module 1. The emergency module 2 includes an emergency base plate and multiple T-shaped clamps 202. The multiple T-shaped clamps 202 are relatively distributed. An auxiliary connecting rod 203 is fixed to both sides of each T-shaped clamp 202. A force-applying plate 205 is fixed to the end of the auxiliary connecting rod 203 away from the T-shaped clamp 202. A T-shaped clamp 202 and... Another T-shaped clamp 202 is provided between the force-applying plates 205. The inner wall of the T-shaped clamp 202 near the force-applying plate 205 is slidably connected to the circumferential surface of the auxiliary connecting rod 203. A return spring 204 is sleeved on the circumferential surface of the auxiliary connecting rod 203 between the multiple T-shaped clamps 202. The emergency module 2 also includes a multi-protruding wheel 206, which is rotatably connected to the inner wall of the emergency base plate. The multi-protruding wheel 206 is located between the force-applying plate 205 and the T-shaped clamp 202 near the force-applying plate 205. The multi-protruding wheel 206 is driven by the drive module 3. V-shaped grooves matching the fixing circumferential groove 201 are opened on the opposite sides of the multiple T-shaped clamps 202.

[0020] Specifically, the fixed end 101 is clamped by multiple T-shaped clamps 202 of the emergency module 2, and the clamping stability of the T-shaped clamps 202 is further improved by the fixed peripheral groove 201, so that the drill body module 1 can maintain stable fixation with the emergency module 2 during operation. When a geological change occurs, the operator can control the rotation of the multi-protruding wheel 206 to release the contact between the multi-protruding wheel 206 and the force plate 205 and the T-shaped clamps 202. Under the release of the elastic potential energy of the return spring 204, the multiple T-shaped clamps 202 quickly move away from each other at both ends, so that the drill body module 1 can quickly separate from the emergency module 2. This emergency release mechanism can separate the drill body module 1 from the main equipment in a timely and reliable manner during geological changes, thus better ensuring the safety of equipment and personnel.

[0021] The drive module 3 includes a drive base plate and a shaft 301. One end of the shaft 301 is fixed to one end of the multi-protruding wheel 206. A fixing ring 302 is keyed to the surface of the shaft 301. A fixing slide 303 is fixed to the circumference of the fixing ring 302. A moving rod 304 is slidably connected to the inner wall of the fixing slide 303. A drive cylinder 305 is rotatably connected to one end of the moving rod 304. One side of the drive cylinder 305 is fixed to the inner wall of the drive base plate.

[0022] Specifically, the drive cylinder 305 of the drive module 3 can quickly drive the shaft 301 to rotate, thereby enabling the multi-protruding wheel 206 to rotate quickly. Furthermore, by driving the moving rod 304 through the drive cylinder 305, the lever arm distance can be greatly increased, reducing the required torque. This allows for a reduction in the size of the drive cylinder 305. Moreover, the response speed of the drive cylinder 305 is faster than that of the motor, making it more suitable for emergency use and improving the equipment's performance.

[0023] A limiting rod 6 is fixed to one end of the drive cylinder 305 near the moving rod 304. A limiting groove 601 is provided on the inner wall of the drive base plate. The limiting groove 601 is arranged parallel to the drive cylinder 305. The end of the limiting rod 6 away from the moving rod 304 is slidably connected to the inner wall of the limiting groove 601.

[0024] Specifically, the parallel advancement of the drive cylinder 305 is assisted by the limiting rod 6 and the limiting groove 601 to prevent deviation caused by vibration or loosening, thereby improving the stability of the equipment and preventing abnormal wear and unstable angular rotation.

[0025] The inner wall of the fixed slider 303 is provided with a protrusion, and the moving rod 304 has a limiting groove 5 on both sides. The inner wall of the limiting groove 5 is slidably connected to the protruding surface of the fixed slider 303.

[0026] Specifically, through the sliding connection between the limiting groove 5 and the protrusion, the drive cylinder 305 can always remain stable and not tilt during the production of the drill body module 1, ensuring the normal operation of the equipment's emergency mechanism.

[0027] Auxiliary arc grooves 4 are provided on the opposite sides of the force-applying plate 205 and the T-shaped clamp 202 near the force-applying plate 205. The inner walls of the auxiliary arc grooves 4 are both set with arc edges.

[0028] Specifically, by creating auxiliary arc grooves 4 near the force plate 205 and T-shaped clamp 202 close to the multi-protruding wheel 206, a positioning point is provided for the multi-protruding wheel 206 when it contacts the two objects. This prevents slippage between the multi-protruding wheel 206 and the force plate 205 and T-shaped clamp 202 due to strong vibrations during underground operations, thus improving the fixing effect. At the same time, both sides of the auxiliary arc groove 4 are set with arc edges, which can provide guidance when in contact with the auxiliary arc groove 4. This allows the T-shaped clamp 202 and the force plate 205 to be stably pushed to both ends when the shaft 301 rotates to drive the multi-protruding wheel 206, preventing wear caused by hard contact and improving the service life of the equipment.

[0029] Positioning posts and corresponding positioning holes are provided on the opposite end faces of the drill body module 1, the emergency base plate of the emergency module 2, and the drive base plate of the drive module 3.

[0030] Specifically, positioning posts and holes ensure stable installation and positioning of each module, guaranteeing the stability of the installation and fit, preventing failure of the fit between equipment components, and improving the yield and stability of the equipment. Example

[0031] refer to Figures 1-7 Based on the structure disclosed in this utility model, the staff applied the deep hole blasting borehole clearing and anti-jamming device described in this utility model in the deep hole blasting drilling operation of a large iron mine.

[0032] The mine uses a down-the-hole drill with a diameter of 165 mm to construct blast holes 25 meters deep, with a special alloy drill bit installed at the front end of the drill body module.

[0033] When the drilling rig reached a depth of 18.7 meters in the basalt layer, it encountered a fault fracture zone. The drill rod was suddenly jammed by collapsed rock, and the torque monitoring system showed that the resistance instantly rose to 850 N·m. The operators immediately activated the emergency procedure, driving the cylinder to push the moving rod 35 mm in 0.3 seconds. This, in turn, caused the shaft to rotate 62 degrees through the fixed sliding member, allowing the protrusions of the multi-protruding wheel to quickly disengage from the auxiliary arc groove.

[0034] The reset spring then releases energy, pushing the two sets of T-shaped clamps to separate outward under the guidance of the auxiliary connecting rod. The V-groove disengages from the fixed peripheral groove of the fixed end, realizing the rapid separation of the drill body module and the emergency module.

[0035] The entire emergency separation process took only 0.8 seconds, successfully preventing the drill pipe from breaking and protecting the drilling rig main unit, which was worth 1.2 million yuan.

[0036] In the subsequent handling, rescuers used hoisting equipment to completely remove the drill module from the stuck hole. After inspection, only the drill bit was slightly damaged and could be reused after replacement.

[0037] This device reduces the time for handling stuck drill accidents in mines from the traditional 4-6 hours to 40 minutes, reduces the cost of handling a single accident by about 85%, and completely avoids the risk of secondary accidents caused by drill rod breakage and residue in the hole due to forced pulling.

[0038] The working principle of this utility model is as follows: Step 1: The fixed end 101 at the front end of the drill body module 1 is inserted into the emergency module 2. Multiple T-shaped clamps 202 are clamped inward under the action of multiple protruding wheel pieces 206. The V-shaped grooves on their inner sides match the fixed peripheral grooves 201 on the fixed end 101, forming a mechanical interlock to ensure a tight connection between the drill body module 1 and the emergency module 2. Under the control of the drive module 3, the multiple protruding wheel pieces 206 are at a specific angle, and their protruding parts press against the force application plate 205 and the auxiliary arc grooves 4 of the T-shaped clamps 202, further strengthening the clamping state and preventing loosening due to vibration.

[0039] Step 2: When the drill body encounters rock bursts, borehole collapse, or foreign object jamming in the hole, the system detects abnormal resistance or triggers an emergency release by manual judgment. The drive cylinder 305 moves quickly, pushing the moving rod 304 to slide within the fixed slide 303. The moving rod 304 drives the fixed slide 303 and the fixed ring 302, which are connected to the drive shaft 301 via a key to rotate. The shaft 301 drives the multi-protruding wheel 206 to rotate, causing its protruding parts to disengage from the auxiliary arc groove 4, releasing the clamping effect on the force plate 205 and the T-shaped clamp 202. The return spring 204 quickly releases its elastic potential energy, pushing the T-shaped clamps 202 on both sides. The T-shaped clamps 202 closer to the force plate 205 slide outward along the auxiliary connecting rod 203, while the T-shaped clamps 202 farther away from the force plate 205 drive the auxiliary connecting rod 203 to slide outward, releasing the clamping of the fixed end 101. The drill body module 1 and the emergency module 2 can be quickly separated to avoid safety risks caused by drill rod breakage, motor burnout, or equipment rebound.

[0040] Step 3: After troubleshooting the hole malfunction, drill module 1 can be realigned with emergency module 2. Drive cylinder 305 reverses its movement, causing the multi-protruding wheel 206 to rotate back to its initial position, pushing the T-shaped clamp 202 back to its original position. The multi-protruding wheel 206 then re-engages into the auxiliary arc groove 4, restoring the clamping state. The reset spring 204 is recompressed, ready for the next emergency release.

[0041] T-shaped clamp 202 clamps and fixes end 101, while multi-protruding wheel 206 presses against auxiliary arc groove 4, ensuring reliable connection between drill module 1 and emergency module 2. In case of obstruction, drive cylinder 305 rotates multi-protruding wheel 206 to release the clamping force, and return spring 204 quickly releases T-shaped clamp 202. Drill module 1 disengages from emergency module 2, preventing equipment damage and personnel injury. After troubleshooting, drive cylinder 305 resets, multi-protruding wheel 206 returns to its original position, and T-shaped clamp 202 re-clamps, ready for reuse.
