Description

Technical Field

[0001] This invention relates to the field of rock crushing technology, and in particular to an intelligent thermal shock-hydraulic splitting composite rock crushing device. Background Technology

[0002] In fields such as rock excavation, mining, and tunnel construction, fracturing hard rock masses (such as granite and basalt) has always been a critical and challenging task.

[0003] While traditional blasting methods are highly efficient, they suffer from problems such as high vibration, noise, flyrock, and severe dust pollution, severely limiting their use in urban areas, near precision facilities, or in situations with extremely high safety requirements. Therefore, static, non-explosive rock-breaking techniques, such as hydraulic rock splitters, have become widely used. Their principle is to use hydraulically driven pistons to apply a huge static thrust to the borehole wall, causing the rock to split. However, when dealing with extremely hard, highly tough, intact rock masses, simple hydraulic rock splitting has inherent limitations such as low rock-breaking efficiency, high energy consumption, and severe equipment wear. This is because the high strength and toughness of rock require higher splitting forces, easily leading to equipment overload and slow formation of the split surface.

[0004] To overcome the above limitations, the industry has explored the idea of ​​combining thermal assistance with mechanical rock breaking. Existing technologies are mainly divided into two categories: The first category is simple preheating and weakening technology, such as heating the rock with electric heating, microwaves, or continuous flames. This method aims to induce microcracks through uneven thermal expansion. However, it has obvious shortcomings: (1) Low weakening efficiency: The slow preheating process is difficult to generate sufficiently intense thermal stress inside the rock, the development of microcracks is limited, and the weakening effect is not significant; (2) Poor energy utilization: A large amount of heat is dissipated in the surrounding rock instead of being concentrated on the target fracture area, resulting in high energy consumption and low efficiency. The second category is a combination of independent thermal rock breaking and hydraulic splitting. That is, a set of independent thermal equipment (such as a large microwave heater or a handheld flame gun) is used to pre-treat the rock first, and then a hydraulic splitting gun is used for operation. This mode has the disadvantages of complex procedures, cumbersome equipment conversion, and long overall operation cycle. More importantly, the two processes are separated in time and space, making it impossible to achieve a rapid and continuous "weakening-splitting" synergy, thus failing to realize the synergistic effect of "1+1>2".

[0005] Therefore, there is an urgent need for an intelligent thermal shock-hydraulic splitting composite rock breaking device to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent thermal shock-hydraulic splitting composite rock breaking device to solve the problems existing in the prior art.

[0007] To achieve the above objectives, the present invention provides the following solution: The present invention provides an intelligent thermal shock-hydraulic splitting composite rock breaking device, comprising: When performing the splitting work, a splitting hole is pre-drilled in the rock mass to be split, and then the splitting gun body is inserted into the splitting hole. A thermal shock assembly is disposed on the rock splitting gun body. When the rock splitting gun body is inserted into the fracture hole, the thermal shock assembly faces the side wall of the fracture hole. Before the rock splitting gun body operates, the thermal shock assembly performs alternating hot and cold shocks on the rock mass. A control component is electrically connected to both the splitting gun body and the thermal shock component to control the intelligent operation of the device.

[0008] Preferably, the splitting gun body includes a central base block, and the thermal shock assembly is mounted on the central base block; side blocks are symmetrically arranged on both sides of the central base block; before operation, the two side blocks are brought together towards the central base block and placed into the fracturing hole; when splitting the rock mass, the control assembly controls the two side blocks to open to both sides.

[0009] Preferably, the splitting gun body is embedded with an independently arranged high-pressure oil circuit, which is connected to an external hydraulic drive module to drive the side blocks on both sides to open.

[0010] Preferably, the thermal shock assembly includes a plurality of thermal shock units electrically connected to the control assembly. The plurality of thermal shock units are disposed on the outer wall of the splitting gun body and are equally spaced, with the thermal shock units facing the sidewall of the splitting hole.

[0011] Preferably, the outer wall of the splitting gun body is provided with equally spaced mounting slots, and a plurality of the mounting slots are provided corresponding to the thermal shock unit, and the thermal shock unit is embedded in the mounting slot.

[0012] Preferably, the thermal shock unit includes a flame heating nozzle and a water cooling nozzle, the outlet directions of which are directed toward the sidewall of the fracture-causing hole; during operation, the flame heating nozzle and the water cooling nozzle, under the control of the control component, alternately act on the sidewall of the fracture-causing hole.

[0013] Preferably, a first pipeline and a second pipeline are embedded in the body of the splitting gun. The first pipeline connects the flame heating nozzle to the external fuel module, and the second pipeline connects the water cooling nozzle to the external water supply module.

[0014] Preferably, the control assembly includes a central controller and a thermal shock element controller that are electrically connected, the thermal shock element controller being electrically connected to the thermal shock unit.

[0015] Preferably, the control component further includes an image acquisition module disposed on the splitting gun body, the image acquisition module being electrically connected to the central controller.

[0016] Preferably, the splitting gun body is provided with a circumferential rotation module, which drives the splitting gun body to rotate in the splitting hole, and the circumferential rotation module is electrically connected to the central controller.

[0017] Compared with the prior art, the present invention has the following advantages and technical effects: The present invention discloses an intelligent thermal shock-hydraulic splitting composite rock breaking device, which deeply integrates subsystems such as thermal shock, visual recognition, and hydraulic splitting to construct an intelligent rock breaking system with adaptive capabilities. It aims to achieve precise and controllable thermal shock treatment based on the actual physical state of the rock mass, solving the bottleneck of the prior art where thermal pretreatment and mechanical splitting are only simple process connections and fail to form an integrated closed loop of perception-decision-execution. It also solves the problems of the existing thermal-assisted rock breaking technology, which suffers from a lack of real-time status feedback, resulting in a rough pretreatment process, unstable weakening effect, and energy waste. The rock splitting gun, as the main body of the device, needs to be used in conjunction with a pre-set fracturing hole. It is inserted into the rock mass to perform the final fracturing operation, serving as the execution vehicle for the hydraulic splitting action. The thermal shock component is integrated into the rock splitting gun body, with its action direction facing the sidewall of the fracturing hole. Its core function is to pre-treat the target rock mass through alternating hot and cold impacts before hydraulic splitting, weakening the rock mass's strength. The control component, as the core control unit, establishes an electrical connection with the rock splitting gun body and the thermal shock component, achieving intelligent overall control of the entire device and coordinating the timing and action logic of thermal shock pre-treatment and hydraulic splitting. The thermal shock unit, combined with the control component integrating temperature sensing and visual recognition modules, provides a data foundation for intelligent control. By monitoring the rock wall temperature, it dynamically adjusts the timing of the fire and water sprays of the thermal shock component, ensuring that each thermal shock is within the optimal efficiency range, completely eliminating the extensive mode of relying on experience for timing. Meanwhile, before operation, the control components automatically scan and analyze the structure of the borehole rock mass, identify the most vulnerable direction, and automatically adjust the attitude of the splitting gun so that the splitting force acts on the weakest point of the rock mass, achieving the most efficient crushing with minimal energy consumption.

[0018] This invention employs intelligent coupling of thermal shock and hydraulic splitting, integrating thermal shock pretreatment with hydraulic splitting action continuously in time and in a unified manner in space, thereby improving automation, rock breaking efficiency, energy utilization, and reducing equipment wear.

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.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1 to 4 As shown, this embodiment provides an intelligent thermal shock-hydraulic splitting composite rock breaking device, comprising: When performing the splitting work, the splitting gun body 3 is pre-drilled in the rock mass to be split, and then the splitting gun body 3 is inserted into the splitting hole. The thermal shock component is installed on the splitting gun body 3. When the splitting gun body 3 is inserted into the fracture hole, the thermal shock component faces the side wall of the fracture hole. Before the splitting gun body 3 works, the thermal shock component performs alternating hot and cold impacts on the rock mass. The control component is electrically connected to the splitting gun body 3 and the thermal shock component respectively, and controls the intelligent operation of the equipment.

[0023] This invention discloses an intelligent thermal shock-hydraulic splitting composite rock breaking device, which deeply integrates subsystems such as thermal shock, visual recognition, and hydraulic splitting to construct an intelligent rock breaking system with adaptive capabilities. It aims to achieve precise and controllable thermal shock treatment based on the actual physical state of the rock mass, solving the bottleneck of existing technologies where thermal pretreatment and mechanical splitting are only simple procedures connected and fail to form an integrated closed loop of perception-decision-execution. It also solves the problems of extensive pretreatment, unstable weakening effect, and energy waste caused by the lack of real-time status feedback in existing thermal-assisted rock breaking technologies. The rock splitting gun body 3, as the main body of the device, needs to be used in conjunction with a pre-set fracturing hole. It is inserted into the rock mass fracturing hole to perform the final fracturing work and serves as the execution carrier for the hydraulic splitting action. The thermal shock component is integrated into the rock splitting gun body 3, with its action direction facing the sidewall of the fracturing hole. Its core function is to pre-treat the target rock mass through alternating hot and cold impacts before hydraulic splitting, thereby weakening the rock mass strength. The control component, as the core control unit, establishes an electrical connection with the rock splitting gun body 3 and the thermal shock component, realizing intelligent overall control of the entire device and coordinating the timing and action logic of thermal shock pre-treatment and hydraulic splitting. The thermal shock unit 4, combined with the control component integrating temperature sensing and visual recognition modules, provides a data foundation for intelligent control. By monitoring the rock wall temperature, it dynamically adjusts the timing of the fire and water spray of the thermal shock component, ensuring that each thermal shock is within the optimal efficiency range, completely eliminating the extensive mode of relying on experience for timing. Simultaneously, before operation, the control components automatically scan and analyze the rock mass structure that causes fractures, identify the most vulnerable direction, and automatically adjust the attitude of the splitting gun to ensure that the splitting force acts on the weakest point of the rock mass, achieving the most efficient crushing with minimal energy consumption. This invention employs intelligent coupling of thermal shock and hydraulic splitting, integrating thermal shock pretreatment with hydraulic splitting action continuously in time and in a unified manner in space, improving automation, rock breaking efficiency, energy utilization, and reducing equipment wear.

[0024] The design is further optimized. The splitting gun body 3 includes a central base block 6, on which the thermal shock component is mounted. Side blocks 5 are symmetrically arranged on both sides of the central base block 6. Before operation, the side blocks 5 are retracted towards the central base block 6 and inserted into the fracturing hole. When splitting the rock mass, the control component controls the side blocks 5 to open to the sides. The splitting gun body 3 consists of the central base block 6 and the side blocks 5 on both sides, forming a splitting structure with central drive and lateral expansion. The thermal shock unit 4 is mounted on the central base block 6 and enters the fracturing hole synchronously with the wedge, close to the hole wall. This ensures that the alternating hot and cold impact energy is concentrated on the area to be split, avoiding energy dispersion and improving the rock mass weakening effect. Before operation, the side blocks 5 retract towards the central base block 6, reducing the overall radial dimension of the body, facilitating smooth insertion into the fracturing hole. This allows it to adapt to smaller diameter fracturing holes or reduce insertion resistance at the same diameter, reducing frictional damage between the hole wall and the device, while simplifying manual insertion and reducing operational difficulty. During the splitting stage, the control component drives the side block 5 to open to both sides. The radial thrust generated by the expansion of the wedge block realizes the splitting of the rock mass, so that the splitting force generated during the opening is evenly applied to both sides of the borehole wall, avoiding the deviation of the splitting direction due to uneven force, ensuring the regularity of the rock breaking cross section, and reducing ineffective crushing.

[0025] The design is further optimized by embedding an independently arranged high-pressure oil circuit within the splitting gun body 3. This high-pressure oil circuit is connected to an external hydraulic drive module to drive the two side blocks 5 to open. One end of the high-pressure oil circuit is connected to the external hydraulic drive module, while the other end directly provides power to the two side blocks 5. The opening action is achieved by driving the side blocks 5 through the pressure of the hydraulic oil. With the help of the pressure adjustment function of the external hydraulic drive module, the opening force and speed of the side blocks 5 can be precisely controlled by changing the oil pressure in the high-pressure oil circuit. This adapts to weakened rock masses of different strengths, avoiding the problem of equipment overload due to excessive force or failure to break rock due to insufficient force. It also reduces the number of moving parts in the body, lowers the probability of mechanical wear, and facilitates subsequent pipeline inspection and maintenance, extending the service life of the equipment.

[0026] In one embodiment of the present invention, a clearance cavity 7 is provided on the side wall of the intermediate base block 6. A hydraulic drive rod 8 connected to the high-pressure oil circuit is provided in the clearance cavity 7. The output end of the hydraulic drive rod 8 extends out of the clearance cavity 7 and is hinged to the inner wall of the side block 5. When the hydraulic drive rod 8 extends, the two side blocks 5 can be pushed to open to both sides through the hydraulic drive rod 8 to achieve splitting.

[0027] Further optimization of the design involves a thermal shock assembly comprising several thermal shock units 4 electrically connected to a control assembly. These units 4 are positioned at equal intervals on the outer wall of the splitting gun body 3, facing the sidewall of the fracture-inducing borehole. The evenly spaced distribution of the thermal shock units 4 on the outer wall of the splitting gun body 3 allows for circumferential, full-coverage thermal shock to the borehole wall, preventing uneven rock weakening due to insufficient impact in localized areas. This ensures consistent rock mass strength in all directions during subsequent splitting, improving rock-breaking stability. The electrical connection between the thermal shock units 4 and the control assembly enables synchronous / asynchronous control of one or more units, achieving precise zonal weakening. The design of the thermal shock units 4 facing the borehole wall ensures that thermal shock energy directly impacts the target rock mass, reducing energy loss to the surrounding environment. Compared to traditional external heating equipment, this significantly improves energy utilization and reduces energy consumption.

[0028] Further optimizing the design, the outer wall of the splitting gun body 3 is provided with equally spaced mounting slots. Several mounting slots correspond to the thermal impact units 4, which are embedded in the mounting slots. The thermal impact units 4 are fixed in the slots by this embedded method, forming an embedded installation structure. This avoids malfunctions caused by loosening or falling off during operation, while also reducing the size of the unit protruding from the outer wall of the body, reducing scratch damage to the hole wall during insertion, and protecting both the unit and the hole wall. The mounting slots allow the thermal impact units 4 to be closer to the body, reducing the gap between the unit and the body and minimizing heat loss during transfer. Simultaneously, the distance between the unit and the hole wall is more uniform, ensuring consistent impact energy intensity for each unit and further improving the uniformity of rock mass weakening. Furthermore, the standardized mounting slots facilitate the batch assembly and replacement of the thermal impact units 4. When a unit malfunctions, it can be directly removed from the slot for replacement without disassembling the entire splitting gun body 3, shortening maintenance time and reducing maintenance costs.

[0029] Further optimizing the design, the thermal shock unit 4 includes a flame-heating nozzle and a water-cooling nozzle, with their outlet directions facing the sidewall of the fracture-inducing borehole. During operation, the flame-heating nozzle and the water-cooling nozzle alternately act on the sidewall of the fracture-inducing borehole under the control of the control component. A first pipeline and a second pipeline are embedded within the splitting gun body 3. The first pipeline connects the flame-heating nozzle to an external fuel module, and the second pipeline connects the water-cooling nozzle to an external water supply module. Each thermal shock unit 4 consists of alternating flame-heating nozzles and water-cooling nozzles, with both nozzles' outlet directions facing the sidewall of the fracture-inducing borehole to ensure precise targeting. The outlet directions of both nozzles face the borehole wall to ensure the thermal shock effect acts directly and efficiently on the target rock mass. During operation, the control unit, based on a preset program or real-time feedback signals, controls two nozzles to work alternately. The flames heat the rock mass, causing it to rapidly expand, while the water spray cools it, causing the surface to contract sharply. Utilizing the immense thermal stress generated by this expansion and contraction, dense microcracks quickly form within the rock mass. Compared to simple heating or cooling, the weakening effect is several times greater, significantly reducing the difficulty of subsequent splitting. By adjusting parameters such as flame temperature, water flow rate and pressure, and alternation frequency, the control unit can adapt to the thermophysical properties of different types of hard rock masses, such as granite and basalt, avoiding insufficient weakening or excessive rock fragmentation due to improper parameters. The nozzles are oriented towards the borehole wall, reducing the diffusion of flames and cooling water into the surrounding environment, lowering noise, dust, and heat pollution during operation, and improving the safety and environmental friendliness of the working environment.

[0030] In one embodiment of the present invention, the flame heating nozzle is a miniaturized diesel nozzle or propane flame injector, which is connected to the fuel / combustion accelerant supply pipeline interface located at the rear of the gun body through a first pipeline for fuel / combustion accelerant supply pre-embedded inside the splitting gun body 3. This interface is then connected to an external fuel tank and compressed air source through a high-pressure hose.

[0031] In one embodiment of the present invention, the water-cooling nozzle is a high-temperature and high-pressure resistant metal nozzle, which is connected to a cooling water supply pipeline interface located at the rear of the splitting gun body 3 via a second pipeline pre-embedded inside the splitting gun body 3. This interface is connected to an external high-pressure water pump via a high-pressure water pipe. The control component mainly consists of a central controller 1 and a thermal shock element controller 2. The central controller 1 serves as the control core of the device, playing a role in intelligent control, while the thermal shock element controller 2 mainly controls the thermal shock unit 4 to perform alternating hot and cold impacts on the rock mass, thereby realizing the automated control of the equipment.

[0032] Further optimization of the scheme involves a control component comprising an electrically connected central controller 1 and a thermal shock element controller 2, with the thermal shock element controller 2 electrically connected to the thermal shock unit 4. The control component mainly consists of the central controller 1 and the thermal shock element controller 2. The central controller 1 serves as the core of the device's control, providing intelligent control, while the thermal shock element controller 2 primarily controls the thermal shock unit 4 to subject the rock mass to alternating hot and cold impacts, thereby achieving automated control of the equipment.

[0033] To further optimize the design, the control components also include an image acquisition module mounted on the splitting gun body 3, which is electrically connected to the central controller 1. The image acquisition module is integrated at the working section end of the splitting gun body 3 and is preferably a waterproof and shockproof industrial endoscope or a wide-angle camera, used to perform 360° scanning imaging of the borehole wall during the lowering of the device.

[0034] In one embodiment of the present invention, the image acquisition module is supplemented with a ring-shaped LED illumination source to ensure clear images are obtained in a dimly lit borehole.

[0035] In one embodiment of the present invention, a non-contact infrared temperature sensor is provided on the outer wall of the splitting gun body 3 to monitor the temperature change of the rock wall surface in real time during the thermal shock process.

[0036] To further optimize the design, a circumferential rotation module is installed on the splitting gun body 3. This module drives the splitting gun body 3 to rotate within the splitting hole. The circumferential rotation module is electrically connected to the central controller 1. The circumferential rotation module is located externally to the splitting gun body 3 or at the hydraulic interface, and is used to receive control commands to precisely rotate and position the entire splitting gun body 3 within the splitting hole.

[0037] In one embodiment of the present invention, the circumferential rotation module may be a rotary chuck driven by a servo motor.

[0038] In one embodiment of the present invention, the circumferential rotation module is equipped with a high-precision encoder, which can achieve precise positioning of the splitting gun with an accuracy better than ±1°.

[0039] In one embodiment of the present invention, the thermal shock unit 4 further includes a rotating connecting ring 10 rotatably connected to the circumferential rotating module. The rotating connecting ring is provided with a plurality of independently provided feeding chambers 9. The feeding chambers 9 are respectively connected to the flame heating nozzle and the water cooling nozzle, and are used to supply materials for flame heating and water cooling, without affecting the rotation adjustment and direction of the splitting gun body 3 in the borehole.

[0040] In one embodiment of the present invention, the central controller 1 is electrically connected to the visual recognition unit, the temperature monitoring unit, the thermal shock unit 4, the directional drive unit and the hydraulic system. It has embedded image processing algorithms and intelligent control logic, which are responsible for processing the data of the sensing module and issuing precise action commands.

[0041] In one embodiment of the present invention, the intelligent control logic of the central controller 1 can preset multiple sets of temperature thresholds and thermal shock parameters according to different rock types to achieve multi-condition adaptive operation.

[0042] Work steps: Preparation stage: Drill a suitable fracturing hole in the hard rock mass to be fractured. Place the working section of this device completely into the hole and connect the hydraulic pipes, fuel pipes, water pipes and other external pipelines and control lines.

[0043] Positioning stage: The form of the opening is observed by the image acquisition module set on the splitting gun body 3, and the geological conditions of the structure to be split are analyzed to determine the weak points in the geology. Then, according to the splitting requirements, the splitting plan is formulated by the central controller 1, and the orientation of the splitting gun body 3 is rotated by the circumferential rotation module so that the flame heating nozzle and water cooling nozzle of the thermal shock unit 4 are oriented towards the direction of the crack to be split, and the two side blocks abut against the two split halves.

[0044] Thermal shock pretreatment stage: Heating Initiation: Turn on the thermal shock element controller 2. Operate the central controller 1 to first open the solenoid valves of all the flame-heating nozzles in sequence. After the fuel and combustion-supporting gas are mixed, they are sprayed out from the nozzles and ignited, forming a high-temperature flame that provides short-term, concentrated high-temperature heating to the rock mass inside the fractured borehole. The heating time can be set within the range of 20 to 40 seconds depending on the lithology.

[0045] Rapid Cooling: Once the heating time is reached, the central controller 1 immediately closes the solenoid valves of the flame-heating nozzles, stopping the heating process. Then, within a very short time of 1-2 seconds, the central controller 1 opens the solenoid valves of all water-cooling nozzles. High-pressure water pumps spray cooling water in atomized or jet form onto the surface of the rock mass, which has just been heated to a scorching state, for rapid cooling. The water-cooling time is typically set to 5 to 15 seconds. This "heating-quenching" process constitutes a complete thermal shock cycle, which can be repeated 1-3 times depending on the hardness of the rock.

[0046] Hydraulic splitting stage: After the thermal shock pretreatment is completed, the central controller 1 immediately starts the hydraulic system of the splitting gun. High-pressure oil enters the cylinder, driving the intermediate base block 6 to violently push the side block 5 outward. Because the surrounding rock mass has generated a large number of microcracks after thermal shock, its overall strength and toughness have been significantly weakened. Therefore, the intermediate base block 6 can easily split the rock with a much lower force than conventional splitting.
