Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, specifically to a tracked chassis for an energy-saving drilling rig for mine exploration that prevents sinking in soft slag heaps. Background Technology

[0002] The anti-sinking and energy-saving track for mining exploration drilling rigs is a special steel track assembly optimized for high-settlement soft ground surfaces such as loose slag heaps and tailings heaps in mines. It relies on widened and lengthened track plates and extended track frames to increase the ground contact area of ​​the whole machine to reduce the grounding specific voltage. It is equipped with a low-power load-sensing hydraulic walking drive system to achieve energy consumption control. It also integrates a buffer tensioning structure, a whole machine lifting mechanism, a slag flushing adaptation protection structure and a fully sealed wear-resistant wheel system. The overall design takes into account the passage requirements of preventing deep sinking, slipping and slag accumulation in loose slag sites, as well as the energy-saving requirements of long-term mobile operation of exploration equipment. The wide track evenly distributes the weight of the drilling rig and the drilling load. It is equipped with anti-slip slag discharge track plates to reduce slag adhesion and accumulation. It is further supplemented by supporting buffer, lifting and cleaning auxiliary structures to mitigate the impact overload and machine malfunction caused by uneven slag surfaces. It is suitable for the harsh working conditions of exploration drilling holes with frequent relocation of tailings heaps in mines. In existing technologies, when the tracked chassis of an energy-saving drilling rig for mining exploration travels on slag heaps for an extended period of time, slag particles can easily become stuck in the track gaps, affecting the track's grip on the ground and the equipment's movement. Furthermore, the track may sink into the ground during operation, thus impacting the equipment's performance and operational efficiency.

[0004] The flushing mechanism also includes a connecting shaft, which is disposed in the middle of the flushing housing. The outside of the connecting shaft is rotatably connected to the middle of the flushing housing. A motor is fixedly connected to the center of the top of the flushing housing, and the output end of the motor is fixedly connected to the top of the connecting shaft. A flushing bracket is provided at the bottom of the connecting shaft, and a flushing tool is fixedly connected to the outside of the flushing bracket near the second mesh plate.

[0005] The rinsing device includes a plastic film, the outside of which is fixedly connected to the outside of the rinsing bracket, an elastic block is provided inside the plastic film, and a friction strip is fixedly connected to the outside of the plastic film.

[0006] Auxiliary support rods are fixedly connected to both sides of the top of the track base, and the top of the auxiliary support rods is fixedly connected to the bottom of the supporting chassis.

[0007] The receiving chassis has grooves at the center of the narrow sides on both sides. A U-shaped plate is inserted into the inner wall of the groove of the receiving chassis. Brush bristles are fixedly connected to the outer side of the U-shaped plate near the track.

[0008] The lifting mechanism includes a lifting base, and a screw is fixedly connected to the center of the top of the lifting base. The screw passes through the base and extends outward, and a nut is threaded onto the outside of the screw.

[0009] Electric push rods are fixedly connected to both sides of the top of the lifting base, and a buffer mechanism is fixedly connected to the external output end of the electric push rods.

[0010] The bottom of the buffer mechanism is rotatably connected to a connecting housing, the outside of the connecting housing is rotatably connected to a connecting block, the bottom of the connecting block is fixedly connected to a lifting base plate, and the bottom of the lifting base plate is fixedly connected to a strip frame.

[0011] The buffer mechanism includes a buffer housing, the inner side of which is slidably connected to the output end of an electric push rod. A circular plate is slidably connected inside the buffer housing, and a second spring is fixedly connected to the bottom of the circular plate. The other side of the second spring is fixedly connected to the bottom of the inner wall of the buffer housing.

[0012] This invention provides a tracked chassis for an energy-saving drilling rig used in mining exploration to prevent sinking in soft slag heaps. It offers the following advantages: I. This energy-saving tracked chassis for mining exploration and sinkhole protection features two fans on both sides of the scouring shell to increase the scouring area and intensity. The fans scour the tracks, removing attached slag and mud, increasing the effective ground contact area to prevent sinking; eliminating abrasives to reduce wear on the track chains and oil seals; preventing chain slippage due to slag jamming; reducing travel resistance and saving energy; slowing chassis corrosion; and facilitating inspection of damaged travel components. The first and second perforated plates are located on the upper and lower sides of the shell opening to prevent external impurities from entering and colliding with the fans, thus avoiding damage and ensuring normal operation of components.

[0013] II. The tracked chassis of this energy-saving drilling rig for mining exploration, designed to prevent sinking of soft slag heaps, uses a motor to control the rotation of the connecting shaft. The connecting shaft controls the flushing bracket to drive the flushing tool to rub against the surface of the second perforated plate, thereby cleaning the mesh of the component, reducing the adhesion of impurities to the component, preventing blockage of the holes, preventing obstruction of airflow, and extending the service life of the component.

[0014] Third, the tracked chassis of this energy-saving drilling rig for soft slag pile anti-sinking mining exploration features an elastic block that supports the plastic film when impurity particles adhere to the surface of the second perforated plate, causing the plastic film to adhere to the surface of the second perforated plate. Furthermore, when particles on the surface of the second perforated plate squeeze the plastic film, the plastic film causes the elastic block to compress and contract. The elastic block then causes the plastic film to adhere according to the surface condition of the component, improving the adhesion effect and ensuring the friction effect. Friction strips are set on the plastic film to achieve a cleaning effect on the component and reduce impurity residue.

[0015] IV. The tracked chassis of this energy-saving drilling rig for mining exploration, designed to prevent sinking in soft slag heaps, uses an electric push rod to control the height of the machine. When the track gets stuck in the slag, it affects the driving effect of the motor. Therefore, the electric push rod is raised and lowered to contact the ground, thereby lifting the machine, increasing the probability of the equipment getting out of the slag heap, eliminating the adhesion resistance between the track and the slag, preventing the machine from sinking deeper and deeper, reducing the load on the walking mechanism, protecting the components, and eliminating the overload stress on the track, motor, and reducer after lifting and unloading, preventing track chain breakage and overload damage to the walking motor.

[0016] Fifth, the tracked chassis of this energy-saving drilling rig for mining exploration with soft slag heap anti-sinking features a connecting shell threaded onto a buffer shell, facilitating component installation and disassembly and enhancing modular design. Furthermore, a connecting block is installed at the bottom of the connecting shell, driving the lifting base plate to be installed at the bottom of the buffer mechanism. A strip frame is placed on the lifting base plate to increase its rigidity, preventing deformation and ensuring optimal equipment operation. Simultaneously, the strip frame divides the contact area between the lifting base plate and the ground surface, preventing the plate from adhering to the ground and affecting equipment operation.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] First embodiment, such as Figures 1 to 4As shown, the present invention provides a technical solution: a tracked chassis for an energy-saving drilling rig for preventing subsidence in soft slag heaps, comprising a supporting chassis 1, which has a square plate structure, chassis slots 2 are provided at the top two sides of the supporting chassis 1, a flushing mechanism 3 is fixedly connected inside the chassis slots 2, chassis grooves 5 are provided on the other two sides of the top of the supporting chassis 1, and a lifting mechanism 4 is fixedly connected to the outside of the chassis grooves 5; The drilling rig tracked chassis also includes a track base 7, with a drive motor 6 fixedly connected to the bottom of the track base 7. A telescopic rod 8 is fixedly connected to the center of the top of the track base 7, and a first spring 9 is sleeved on the outside of the telescopic rod 8. When the drive motor 6 moves on the slag heap, it moves with the terrain. The chassis 1 controls the telescopic rod 8 to compress and contract the first spring 9, thereby playing a role in shock absorption and buffering, cushioning ground impact, protecting the chassis and running gear, improving the stability of the drive motor 6 during movement, and evenly distributing ground pressure. The system reduces sinking and adapts to ground undulations, ensuring that multiple sets of support rollers always remain in contact with the slag ground, preventing excessive pressure at any single point, reducing local ground pressure, minimizing sinking and unilateral subsidence, reducing vibration and noise, and improving overall machine stability. The flushing mechanism 3 is located in the chassis slot 2 of the chassis 1, with its air vents aligned with the track area. The flushing mechanism 3 flushes and cleans the track, removing accumulated slag, maintaining the designed ground contact area, reducing specific pressure, preventing soft slag from accumulating and sinking, and ensuring normal equipment operation.

[0021] Auxiliary support rods 10 are fixedly connected to both sides of the top of the track base 7, and the top of the auxiliary support rods 10 is fixedly connected to the bottom of the supporting chassis 1. The auxiliary support rods 10 are located between the track base 7 and the supporting chassis 1. The auxiliary support rods 10 rise and fall with the telescopic rod 8 to support the supporting chassis 1, thereby improving the stability of the components, avoiding excessive shaking during movement, avoiding affecting the walking effect of the equipment, and thus ensuring the normal operation of the equipment.

[0022] The receiving chassis 1 has grooves centered on both narrow sides. U-shaped plates 11 are inserted into the inner walls of these grooves. Brush bristles 12 are fixedly connected to the outer side of the U-shaped plates 11 near the track. The U-shaped plates 11 are inserted from the side of the receiving chassis 1 to quickly secure the components. The brush bristles 12 are located at the bottom of the U-shaped plates 11. During track rotation, the brush bristles 12 rub against the track, mechanically cleaning it and removing particles to reduce residue and prevent impact on track grip.

[0023] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 4 to 6As shown, the lifting mechanism 4 includes a lifting base 41. A screw 42 is fixedly connected to the center of the top of the lifting base 41. The screw 42 passes through the receiving base 1 and extends outward. A nut 43 is threadedly connected to the outside of the screw 42. The screw 42 is located on the top of the lifting base 41. The lifting base 41 drives the screw 42 to pass through the receiving base 1. After the screw 42 passes through the receiving base 1, it is secured to the bottom of the receiving base 1 by the nut 43. Then, the nut 43 is tightened to fix it to the bottom of the receiving base 1, thereby achieving the function of quickly fixing the component, which facilitates the installation and disassembly of the component and reduces the difficulty of subsequent maintenance and replacement of the component.

[0024] Electric push rods 44 are fixedly connected to both sides of the top of the lifting base 41, and a buffer mechanism 45 is fixedly connected to the external output end of the electric push rods 44. The height of the lifting control component is controlled by the extension and retraction of the electric push rods 44. When the track gets stuck in the slag, it affects the walking effect of the drive motor 6. Therefore, the electric push rods 44 are raised and lowered to contact the ground, thereby lifting the machine, increasing the probability of the equipment getting out of the slag, detaching it from the soft slag layer, eliminating the adhesion resistance between the track and the slag, preventing it from getting deeper and deeper, reducing the load on the walking mechanism, protecting the parts, and eliminating the overload stress on the track, motor, and reducer after lifting and unloading, preventing the track chain from breaking and the walking motor from being overloaded and damaged.

[0025] The bottom of the buffer mechanism 45 is rotatably connected to a connecting housing 47. A connecting block 46 is rotatably connected to the outside of the connecting housing 47. A lifting base plate 48 is fixedly connected to the bottom of the connecting block 46. A strip frame 49 is fixedly connected to the bottom of the lifting base plate 48. The connecting housing 47 is threaded onto the buffer mechanism 45 to facilitate the installation and disassembly of the components and improve the modular design of the components. Secondly, the connecting block 46 is set at the bottom of the connecting housing 47, which drives the lifting base plate 48 to be installed at the bottom of the buffer mechanism 45. The strip frame 49 is set on the lifting base plate 48 to increase the rigidity of the lifting base plate 48, prevent the plate from deforming, and prevent it from affecting the operation of the equipment. At the same time, the strip frame 49 divides the contact area between the lifting base plate 48 and the bottom surface, preventing the plate from sticking to the ground and affecting the operation of the equipment.

[0026] The buffer mechanism 45 includes a buffer housing 451. The inner side of the buffer housing 451 is slidably connected to the output end of the electric push rod 44. A circular plate 452 is slidably connected inside the buffer housing 451. A second spring 453 is fixedly connected to the bottom of the circular plate 452. The other side of the second spring 453 is fixedly connected to the bottom of the inner wall of the buffer housing 451. The circular plate 452 is fixedly connected to the output end of the electric push rod 44. When the electric push rod 44 pushes the components toward the ground to lift the tracks, the circular plate 452 compresses and contracts the second spring 453, thereby playing a role in shock absorption and buffering. During the process of the tracks getting out of trouble, the impact load is buffered, the self-weight of the equipment and the reaction force of the slag are smoothly transmitted, and rigid impact damage to the lifting components, track walking assembly and drilling rig body is avoided. At the same time, the machine body sway is mitigated, the stress state is stabilized, local stress concentration is reduced, the instantaneous load fluctuation caused by the undulation of the slag ground is reduced, the smoothness of the lifting operation is improved and the service life of the entire mechanism is extended.

[0027] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 9 As shown, the flushing mechanism 3 includes a flushing housing 31, which is disposed inside the chassis slot 2. The outside of the flushing housing 31 is fixedly connected to the inner wall of the chassis slot 2, and the inside of the flushing housing 31 has housing slots 32 on both sides. A blower 33 is located in the middle of the housing slot 32. The outer side of the blower 33 is fixedly connected to the inner wall of the housing slot 32. A first perforated plate 34 is fixedly connected to the upper side of the inner wall of the housing slot 32, and a second perforated plate 35 is fixedly connected to the lower side of the inner wall of the housing slot 32. Two blowers 33 are arranged on both sides of the inside of the flushing housing 31 to increase the flushing area and improve the flushing force. The two blowers 33 flush the track to remove attached slag and mud, increase the effective grounding area to prevent sinking, eliminate abrasives to reduce wear on the track chain and oil seals, avoid slag jamming and chain derailment failure, reduce walking resistance and save energy, slow down chassis corrosion, and facilitate inspection of damage to walking components. The first perforated plate 34 and the second perforated plate 35 are located on the upper and lower sides of the housing slot 32 to block external impurities from entering, prevent impurities from colliding with the blower 33, avoid damage to the blower 33, and ensure normal operation of components.

[0028] The flushing mechanism 3 also includes a connecting shaft 37, which is located in the middle of the flushing housing 31. The outside of the connecting shaft 37 is rotatably connected to the middle of the flushing housing 31. A motor 36 is fixedly connected to the center of the top of the flushing housing 31, and the output end of the motor 36 is fixedly connected to the top of the connecting shaft 37. A flushing bracket 38 is provided at the bottom of the connecting shaft 37, and a flushing tool 39 is fixedly connected to the outside of the flushing bracket 38 near the second mesh plate 35. The connecting shaft 37 is rotated by the motor 36, and the connecting shaft 37 controls the flushing bracket 38 to drive the flushing tool 39 to rub against the surface of the second mesh plate 35, thereby cleaning the mesh of the component, reducing the adhesion of impurities to the component, avoiding blockage of the holes, preventing obstruction of airflow, and extending the service life of the component.

[0029] The rinsing tool 39 includes a plastic film 391, which is fixedly connected to the outside of the rinsing bracket 38. An elastic block 392 is disposed inside the plastic film 391, and a friction strip 393 is fixedly connected to the outside of the plastic film 391. When impurity particles adhere to the surface of the second mesh plate 35, the elastic block 392 supports the plastic film 391, causing it to adhere to the surface of the second mesh plate 35. Furthermore, when particles on the surface of the second mesh plate 35 press against the plastic film 391, the plastic film 391 causes the elastic block 392 to compress and contract. The elastic block 392 then causes the plastic film 391 to adhere according to the surface condition of the component, improving the adhesion effect and ensuring the friction effect. The friction strip 393 is disposed on the plastic film 391, thereby achieving a cleaning effect on the component and reducing impurity residue.

[0030] In use, a track base 7 is installed on top of the drive unit 6, and a telescopic rod 8 is installed at the center of the top of the track base 7. A support chassis 1 is installed on the top of the telescopic rod 8, and a first spring 9 is sleeved on the outside of the telescopic rod 8. During the movement of the drive unit 6, the telescopic rod 8 is extended and retracted according to the terrain, so as to adapt to the undulation of the ground and keep the multiple sets of support rollers in contact with the slag ground. This prevents excessive local single-point pressure, reduces local ground pressure, reduces sinking and one-sided subsidence, reduces vibration and noise, and improves the stability of the whole machine. Auxiliary support rods 10 are set on both sides of the telescopic rod 8. The auxiliary support rods 10 extend and retract with the telescopic rod 8 to improve the stability of the components, avoid excessive shaking during movement, avoid affecting the walking effect of the equipment, and thus ensure the normal operation of the equipment. The top of the chassis 1 is equipped with two sets of lifting mechanisms 4 and four sets of flushing mechanisms 3. The flushing mechanisms 3 flush the track from four directions to remove accumulated slag, maintain the designed ground contact area, reduce specific pressure, prevent soft slag from accumulating and getting stuck in the car, and ensure normal operation of the equipment; eliminate abrasive wear caused by slag particles, reduce wear on the track chain, wheel system seals, and travel motor, clear the meshing gap of the wheel teeth, prevent slag from getting stuck and causing chain derailment and travel jamming, and reduce the overall equipment failure rate and extend the service life of the travel system; When the drive motor 6 travels on the slag pile, there is a possibility that the drive motor 6 may get stuck inside the slag pile. The lifting mechanism 4 squeezes the ground, thereby lifting one side of the drive motor 6 to achieve the effect of lifting the machine, increasing the probability of the equipment getting out of the slag, removing the adhesion resistance between the track and the slag, preventing it from getting deeper and deeper, reducing the load on the traveling mechanism, protecting the parts, and eliminating the overload stress on the track, motor, and reducer after lifting and unloading, preventing the track chain from breaking and the traveling motor from being overloaded and damaged.
