Description

Technical Field

[0001] This application relates to the field of mining equipment technology, and in particular to a fracturing expansion device, an intelligent operation robot, and a construction method. Background Technology

[0002] In mining operations and infrastructure construction, when blasting is required at the construction site, conventional explosives are typically used. This involves using explosives to detonate in air, water, or soil to generate shock waves and thermal vibrations, thus achieving blasting. However, in the conventional blasting industry, workers must manually fill the blast holes at close range. Because conventional explosives are flammable and explosive, this process is prone to safety accidents. Summary of the Invention

[0003] This application provides a fracturing expansion device, an intelligent operating robot, and a construction method to solve the problem of safety accidents that are prone to occur when workers operate traditional explosives at blasting sites in existing mining operations.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, a fracturing expansion device is provided, comprising: an attachment and at least one fracturing expansion bag connected thereto; the fracturing expansion bag includes a bag body and a fracturing expansion material filled in the bag body; the bag body is a water-permeable and air-permeable material, and a combustion-supporting medium can permeate through the bag body to wet the fracturing expansion material or fill the gaps between the fracturing expansion materials; the attachment is connected to one end of the fracturing expansion bag; or along the extending direction of the fracturing expansion bag, the attachment passes through both ends of each fracturing expansion bag, and a gap is maintained between two adjacent fracturing expansion bags.

[0005] Compared with the prior art, this application has the following beneficial effects: The fracturing expansion device provided in this application differs from traditional explosives. The fracturing expansion bag contains safe fracturing material, and during use, it achieves its fracturing effect with the aid of a combustion-supporting medium. This design allows for the separate transportation and storage of the combustion-supporting medium and the fracturing expansion bag, with the combustion-supporting medium added at the work site. Compared to traditional explosives, this design improves the safety of transportation and storage.

[0006] In one alternative embodiment, the bag is cylindrical or elongated and sealed at both ends.

[0007] In one alternative embodiment, the bag body is flexible.

[0008] In one alternative embodiment, the bag body is made of an antistatic material.

[0009] In one alternative embodiment, the bag body is a cloth bag.

[0010] In one alternative embodiment, the fracturing expansion material is at least one or a combination of pulverized coal, carbon powder, and biomass fiber.

[0011] In one alternative embodiment, the rupture-inflating device further includes an attachment; the attachment is connected to one end of the rupture-inflating bag, or extends through both ends of each rupture-inflating bag along the extension direction of the rupture-inflating bag, with a gap maintained between adjacent rupture-inflating bags.

[0012] Secondly, an intelligent operating robot for deploying the fracturing expansion device is provided, comprising: a mobile vehicle and a control module, at least one medium tank, at least one deployment device, and a burial assembly cooperating with the deployment device, all mounted on the mobile vehicle; the attachment is a rope, and the deployment device carries the fracturing expansion bag through the rope and deploys it into a blast hole; the medium tank adds the combustion-supporting medium into the fracturing expansion bag; the burial assembly is used to convey burial material into the blast hole and burial the fracturing expansion bag deployed into the blast hole; the control module is connected to the controllers of the deployment device, the burial assembly, and the mobile vehicle respectively.

[0013] Compared with existing technologies, the intelligent work robot provided in this application has the following beneficial effects: The fracturing expansion bag containing fracturing material is automatically placed into the blast hole by a delivery device that communicates with the control module. This eliminates the need for manual placement of traditional explosives at the blasting site, reducing the probability of accidents and improving the safety of life and property. Furthermore, the fracturing expansion device deployed by the intelligent robot in this application uses fracturing material instead of traditional explosives, further reducing the probability of accidents caused by the flammable and explosive nature of traditional explosives.

[0014] Thirdly, a construction method using the fracturing expansion device is provided, comprising the following steps: Step 1: Drilling holes at the site where construction is required to form the blasting hole; Step 2: Laying a detonating wire and an ignition device, wherein there is at least one ignition device connected in series via the detonating wire, the ignition device is placed in the blasting hole, and the ignition device is connected to an initiator via the detonating wire; Step 3: Adding the combustion-supporting medium to the fracturing expansion bag, using a delivery actuator to place the fracturing expansion device into the blasting hole, and covering the blasting hole with sand; Step 4: Moving the delivery actuator away from the work site and remotely activating the initiator.

[0015] Compared with the prior art, this application has the following beneficial effects: This application integrates the fracturing expansion device with the delivery mechanism, which can automatically deliver the fracturing expansion bag into the preset blast hole. This eliminates the need for operators to manually deliver traditional explosives into the blast hole at the blasting site, reducing the probability of safety accidents and improving the safety of life and property at the blasting site.

[0016] In one optional embodiment, the delivery execution mechanism is the intelligent operation robot as described in claim 7; the steps of adding the combustion-supporting medium to the rupture-inducing expansion bag in step three and the step of burying the blast hole with sand are both completed by the intelligent operation robot.

[0027] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0028] See Figure 1 and Figure 2 As shown, this application provides a fracturing expansion device, including a fracturing expansion bag 30 and a rope for connecting the fracturing expansion bag. The fracturing expansion bag 30 includes a bag body and a fracturing expansion material filled inside the bag body. The bag body is cylindrical and sealed at both ends; the bag body is made of a water-permeable and air-permeable material, allowing the combustion-supporting medium to permeate through the bag body to wet the fracturing expansion material or fill the gaps in the fracturing expansion material. It is understood that this application does not limit the shape of the bag body, but preferably has a shape adapted to the burst hole, such as a cylindrical or elongated shape.

[0029] The fracturing expansion device provided in this application is typically used in blasting operations such as mining, and can also be used in other operations requiring expansion and fracturing, such as engineering construction. The fracturing expansion device provided in this application differs from traditional explosives; the fracturing expansion bag 30 contains safe fracturing material, and the expansion and fracturing effect is achieved with the aid of a combustion-supporting medium. This design allows for separate transportation and storage of the combustion-supporting medium and the fracturing expansion bag 30, with the combustion-supporting medium added at the work site. Compared to traditional explosives, this improves the safety of transportation and storage.

[0030] Specifically, the fracturing expansion bag 30 in this embodiment includes an outer bag body and a fracturing expansion material filled inside the bag body. The bag body is made of a flexible material, preferably an antistatic cloth bag; the bag body is cylindrical or elongated to fit the blast hole, facilitating its placement into the blast hole. Using an antistatic cloth bag as the bag body allows the entire fracturing expansion bag 30 to deform easily. This design reduces the requirements for blast hole construction during on-site operations, and the fracturing expansion bag 30 can also adapt well to bending during drilling. Furthermore, the use of an antistatic cloth bag provides good antistatic properties, improving safety during transportation, storage, and use. It is understood that the cloth bag has good air and water permeability, facilitating the penetration of the combustion-supporting medium into the bag and saturating the entire fracturing expansion bag 30.

[0031] The fracturing and expanding material in this embodiment is selected from at least one or a combination of pulverized coal, carbon powder, and biomass fiber. These materials, when impregnated with a combustion-supporting medium, can be rapidly ignited, generating a large amount of gas and thus expanding and fracturing. A combination of pulverized coal, carbon powder, and biomass fiber is preferred, with a ratio of 7:2:1 yielding the best results. It is understood that the biomass fiber can be cotton, wood chips, paper, cloth, straw fiber, etc., and there are no restrictions here. The moisture content of the biomass fiber is controlled between 6% and 12%.

[0032] The combustion-supporting medium can be at least one or a combination of combustion-supporting gas, combustion-supporting oil, or liquid oxygen. This application embodiment does not limit this and can be adjusted according to implementation needs. In this embodiment, liquid oxygen is preferentially selected as the combustion-supporting medium. Liquid oxygen has a lower cost and is highly volatile, making post-explosion handling safer. Because of its volatility, if there are unexploded or undisturbed items, the liquid oxygen will evaporate in a short time, greatly reducing the danger upon approach. Furthermore, the gas produced after the reaction of liquid oxygen with the fracturing expansion material provided in this application embodiment is pollution-free carbon dioxide, reducing the emission of toxic gases compared to traditional "nitrate" explosives.

[0033] It is understood that the rupture-inducing expansion bag 30 in the embodiments of this application can be used in series, and the number of rupture-inducing expansion bags 30 used in series can be adjusted according to the depth of the rupture hole and the size of the rupture-inducing expansion bag.

[0034] To facilitate the deployment of the fracturing expansion device provided in this application, such as for easy coordination with deployment execution mechanisms like on-site intelligent operation robots, the fracturing expansion device provided in this application also includes an attachment for connecting the fracturing expansion bag 30. The attachment can be a rope such as a traction rope or a lifting rope.

[0035] When a single fracturing expansion bag needs to be placed into the blast hole and is lowered into the hole by hoisting, one end of the rope is connected to one end of the fracturing expansion bag, and the other end is connected to the placement device. Alternatively, one end of the rope can run through the entire fracturing expansion bag 30 along its length, with the free end of the rope extending a certain distance beyond the bag. This arrangement allows the naturally hanging end of the rope to serve as a reference for aligning with the blast hole. When multiple fracturing expansion bags need to be placed into the blast hole, the multiple bags can be spaced apart on the rope. That is, the rope enters from one end of the bag 30 and exits from the other end along its extension direction (which can be the length direction of the bag), so that multiple bags are connected in series on the same rope, with a certain distance between adjacent bags. After the rope passes through the bag, both ends of the bag are sealed using cable ties or other binding devices. It is understood that the spacing between adjacent rupture-inducing expansion bags 30 can be set according to actual needs, and this application embodiment does not limit this.

[0036] It is understandable that, in order to ensure the stability of the rope-driven rupture expansion bag 30, in this embodiment of the application, the rope can be knotted inside the rupture expansion bag 30 before being passed out of the rupture expansion bag 30.

[0037] When using the fracturing expansion device provided in this application, a blasting hole is first drilled at the work site as needed. Then, multiple ignition devices are connected in series using a detonating wire. The ignition devices can be electronic matches; this application does not impose any restrictions on the ignition devices. Next, the ignition devices are placed into the blasting hole, and the detonating wire is connected to the detonator. After the detonating wire and ignition devices are laid, the fracturing expansion device of this application is placed into the blasting hole using a delivery mechanism. Then, the blasting hole is covered with fine sand. Finally, the delivery mechanism is driven away from the work site, and the detonator is remotely activated to complete the blasting operation.

[0038] It is understood that the delivery execution mechanism used in this application may be an intelligent operation robot used in conjunction with the fracturing expansion device provided in this application, or it may be a drone, a lifting balloon or other lifting and delivery device.

[0039] This application also provides a smart operating robot for use with the deployment of the direct expansion device.

[0040] See Figure 1 and Figure 2As shown, this application embodiment provides an intelligent operation robot 100, including a mobile vehicle 10 and a delivery device 20, a medium tank (not shown), a burial assembly, and a control module disposed on the mobile vehicle 10. Along the forward direction of the mobile vehicle 10, the delivery device 20 is disposed at the front end of the mobile vehicle 10. The delivery device 20 carries a fracturing expansion bag 30 via a rope connected to a fracturing expansion device and delivers it to the blast hole. The fracturing expansion bag 30 contains fracturing material, and the medium tank adds a combustion-supporting medium to the fracturing material. The burial assembly includes a sand box 40 and a conveying device. Along the forward direction of the mobile vehicle 10, the sand box 40 is disposed at the rear end of the mobile vehicle 10. The conveying device extends along the forward direction of the mobile vehicle, with its front end engaging with the blast hole on the ground and its rear end engaging with the blast hole. The sand box 40 contains burial material, and the conveying device is configured to convey the burial material to the blast hole and bury the fracturing expansion bag 30. The control module is signal-connected to the delivery device 20, the burial assembly, and the drive mechanism of the mobile vehicle 10. It is understood that this application does not limit the position of the dispensing device 20, the medium tank, the sand tank, and other structures on the mobile vehicle 10, and can be adjusted according to actual needs. In this application, the dispensing device 20 is located at the front of the mobile vehicle to facilitate the dispensing of the fracturing expansion device, and the sand tank is located at the rear of the mobile vehicle to increase the vehicle's counterweight and ensure the stability of the mobile vehicle during dispensing.

[0041] Specifically, the intelligent operation robot 100 in this embodiment is typically used in blasting operations in mining, and can automatically place the fracturing expansion bag 30 for blasting into a preset blast hole. It is understood that the intelligent operation robot 100 in this embodiment can also be used in other fields requiring blasting and fracturing, such as infrastructure construction. The mobile vehicle 10 is similar in structure to a car in the prior art, including a vehicle body 11, a drive mechanism, a walking mechanism 12, etc. The walking mechanism 12 is located at the bottom of the vehicle body 11. The walking mechanism 12 can be a wheeled walking mechanism or a tracked walking mechanism. To cope with the complex terrain at the blasting site, a tracked walking mechanism is preferred.

[0042] Understandably, the mobile vehicle 10 could be a fuel-powered vehicle. For example, the drive mechanism includes a fuel engine and a transmission connected to it, through which power is transmitted to the traveling mechanism to move the mobile vehicle 10. Similarly, the mobile vehicle 10 can move forward, backward, and turn to adjust its position, which will not be elaborated further here.

[0043] It is understood that the intelligent operation robot 100 provided in this application embodiment has a delivery device 20, a medium box, and a burial component installed on the vehicle body 11, which are not limited to one, but can be multiple.

[0044] The fracturing expansion bag 30 provided in this application differs from traditional explosives. The fracturing expansion bag 30 contains an expanding fracturing material and requires a combustion-supporting medium to achieve its expanding fracturing effect. The fracturing expansion bag 30 includes an antistatic dustproof bag, inside which the expanding fracturing material is sealed. The expanding fracturing material includes soot and fibrous materials, and is sealed within the antistatic dustproof bag. The expanding fracturing material includes soot and fibrous materials. The combustion-supporting medium can be at least one or a combination of combustion-supporting gas, combustion-supporting oil, or liquid oxygen. This application does not limit this and can be adjusted according to implementation needs.

[0045] This configuration allows the fracturing expansion bag 30 and the combustion-supporting medium to be stored separately during transportation or storage, with the latter preferably added at the blasting site. Compared to traditional explosives, this improves the safety of transportation and storage.

[0046] Based on this, the mobile vehicle 10 is equipped with a medium tank (not shown in the figure), which adds a combustion-supporting medium to the rupture-inducing expansion bag 30. The medium tank contains a combustion-supporting medium, and the method of adding the combustion-supporting agent to the rupture-inducing expansion bag 30 according to actual needs includes, but is not limited to, soaking and spraying.

[0047] For example, in one embodiment, the medium tank contains liquid oxygen, and the rupture-inducing expansion bag 30 located within the medium tank is immersed in the liquid oxygen to ensure that the rupture-inducing expansion bag material is fully immersed in the liquid oxygen. For example, the medium tank is connected to a liquid oxygen source via a delivery pipeline, and the release of liquid oxygen is controlled by a control valve.

[0048] In another embodiment, the medium tank contains liquid oxygen and is equipped with a spraying device. The spraying device is connected to a combustion-supporting medium and can spray the crack-inducing expansion bag 30 located in the medium tank so that the liquid oxygen wets the crack-inducing expansion bag 30 and the crack-inducing expansion material therein.

[0049] For example, the spraying device is connected to a liquid oxygen source via a delivery pipeline. The latter has a medium tank containing liquid oxygen. The spraying device is connected to the liquid oxygen in the medium tank. That is, the medium tank can not only soak the rupture-inducing expansion bag 30, but also spray the rupture-inducing expansion bag 30 to meet different needs.

[0050] In this embodiment, the fracturing expansion bag 30 can be connected to a rope and then to the delivery device 20. Along the forward direction of the mobile vehicle 10 (X-axis direction in the figure), the delivery device 20 can be located at the front end of the mobile vehicle 10, and the delivery device 20 is connected to the fracturing expansion bag 30 via a rope. When there are multiple delivery devices 20, they can be located at other positions on the mobile vehicle 10. For example, if there are three delivery devices, one can be located at the front end of the mobile vehicle 10, and the other two at the two sides of the mobile vehicle. Correspondingly, there are also three fracturing expansion devices.

[0051] For example, the delivery device can suspend the rupture-inducing expansion bag 30 by a rope. By operating the delivery device, the rupture-inducing expansion bag can be positioned above and opposite the rupture hole at the front end of the mobile vehicle 10. Then, the connection between the rope and the rupture-inducing expansion bag 30 can be released, and the rupture-inducing expansion bag 30 can be delivered into the rupture hole 30. That is, the delivery device can automatically deliver the rupture-inducing expansion bag into the rupture hole at the front end of the mobile vehicle 10.

[0052] Preferably, the medium tank is positioned close to the dispensing device 20 to facilitate the dispensing of the fracturing expansion bag 30 containing the added combustion-supporting medium from the medium tank into the rupture hole. For example, along the forward direction of the mobile vehicle 10, the medium tank is located behind the dispensing device 20. This embodiment of the application does not limit this, as long as it satisfies the requirement of dispensing the fracturing expansion bag 30 into the rupture hole located at the front end of the mobile vehicle 10. When there are multiple dispensing devices 20, the medium tank can be set to one, and multiple fracturing expansion devices can be held in the medium tank at the same time; the number of medium tanks can also be set to the same number as the number of dispensing devices, and each fracturing expansion device adapted to the dispensing device 20 can be held separately.

[0053] The burial assembly provides burial material for burying the fracturing expansion bag 30 that has been placed into the blast hole. This burial material can be sand or gravel. Further, a conveying device is provided between the sand box 40 and the blast hole. This conveying device conveys the burial material into the blast hole and buries the fracturing expansion bag 30. When multiple placement devices 20 are provided, the burial assembly can also be provided in the same number as the placement devices. For example, if there are three placement devices, there are also three conveying devices, located near the placement devices 20 at the end closest to the blast hole. Similarly, there can be three sand boxes 40, corresponding to the other end of the conveying devices. Alternatively, there can be one sand box 40, with three conveying devices corresponding to one sand box 40.

[0054] For example, the sand box 40 has a discharge port that cooperates with the conveying device. Along the forward direction of the mobile vehicle 10, the sand box 40 is located at the rear end of the mobile vehicle 10, and the conveying device extends along the forward direction of the mobile vehicle 10. The front end of the conveying device cooperates with the blasting hole, and the rear end of the conveying device cooperates with the discharge port of the sand box 40, so that the sand and gravel in the sand box 40 fall onto the conveying device.

[0055] It is understood that the conveying device is configured as a screw conveyor or a conveyor belt, and this application embodiment does not limit this. In one embodiment, the conveying device is a screw conveyor, the inlet of the screw conveyor is opposite to the outlet of the sand box 40, and the sand and gravel flowing out of the outlet can enter the inlet of the screw conveyor and fall into the blast hole through the outlet of the screw conveyor.

[0056] Furthermore, in another alternative embodiment, the conveying device is configured as a conveyor belt, which is opposite to the discharge port of the sand box 40, so that the sand and gravel flowing out of the sand box 40 can fall onto the conveyor belt. Further, the conveying device also includes a transmission power mechanism and a first steering wheel and a second steering wheel connected thereto. The first steering wheel and the second steering wheel are respectively located at the rear end and front end of the moving vehicle 10, and both ends of the conveyor belt are wound around the first steering wheel and the second steering wheel, respectively. The transmission power mechanism can be two synchronous motors that drive the first steering wheel and the second steering wheel, respectively. The synchronous motors can drive the conveyor belt to move, thereby conveying the sand and gravel into the blasting hole.

[0057] To achieve automated operation of the intelligent work robot 100, the intelligent work robot 100 also includes a control module. This control module is connected to the controllers of the delivery device 20, the burial assembly, the mobile vehicle 10, and the control valve controlling the delivery of the combustion-supporting medium, etc., to issue work instructions to the intelligent work robot 100. It is understood that the control module can be connected to a remote control center, serving as a communication module to receive instructions from the remote control center, which can be a control platform or control terminal.

[0058] Compared to existing blasting operations where workers manually fill blast holes with traditional explosives at close range on-site, the intelligent robot 100 provided in this application uses a delivery device 20 to automatically deliver fracturing expansion bags 30 containing fracturing material into the blast holes. The delivery device 20 is communicatively connected to a control module, eliminating the need for manual delivery of traditional explosives at the blast site. This reduces the probability of accidents and improves the safety of life and property at the blasting site. Furthermore, the intelligent robot also completes the processes of adding combustion-supporting media to the fracturing expansion material within the fracturing expansion bags 30 and burying the bags with sand after delivery into the blast holes, further enhancing the safety of the blasting site.

[0059] Meanwhile, this application uses an expansion-inducing fracturing material instead of traditional explosives, which reduces the probability of safety accidents due to the flammable and explosive nature of traditional explosives. Furthermore, the expansion-inducing bag 30 and the combustion-supporting medium can be stored separately during transportation or storage, with the combustion-supporting medium added to the expansion-inducing bag 30 at the blasting site. Compared to traditional explosives, this improves the safety of transportation and storage.

[0060] This application provides different dispensing devices 20 for different scenarios of dispensing the rupture-inducing expansion bag 30. The implementation methods of the dispensing device 20 are described in detail below: First implementation method: When multiple randomly ordered rupture holes need to be selectively deployed with fracturing expansion bags 30, the deployment device 20 includes a rotatable traction guide wheel. Correspondingly, the fracturing expansion bag device includes multiple fracturing expansion bags 30, and the attachment is configured as a traction rope adapted to the traction guide wheel. The multiple fracturing expansion bags 30 can be spaced apart on the traction rope, that is, the traction rope passes through one end of the fracturing expansion bag 30 and exits from the other end along the extension direction of the fracturing expansion bag 30 (which can be the length direction of the fracturing expansion bag), so that the multiple fracturing expansion bags 30 are connected in series on the same traction rope, and a certain interval is maintained between adjacent fracturing expansion bags 30. After the traction rope passes through the fracturing expansion bag, both ends of the fracturing expansion bag are sealed using binding devices such as cable ties. It is understood that the interval between adjacent fracturing expansion bags 30 within the medium tank can be set according to actual needs, and this embodiment does not limit this.

[0061] Multiple fracturing expansion bags 30, which are strung together by traction ropes, can be placed into the medium tank at the same time and arranged in a zigzag pattern. After the multiple fracturing expansion bags 30 are soaked in the combustion-supporting medium, they are transferred to their respective blast holes by the delivery device 20.

[0062] During transfer, a locking device is provided at one end of the traction rope that exits the fracturing expansion bag 30, such as by tying a knot at its free end. The traction guide wheel has an opening groove corresponding to this locking device. When the traction guide wheel rotates, it drives the traction rope to move, thereby pulling the fracturing expansion bag 30 out of the medium tank. The rotation path of the traction guide wheel matches the rupture hole, and the traction guide wheel rotates to at least one position where the fracturing expansion bag 30 is opposite to the rupture hole. During the rotation of the traction guide wheel, at least part of the traction guide wheel is located on the outer front end of the moving vehicle 10. Under the action of gravity, when the free end of the traction rope leaves the traction guide wheel and remains vertical, the free end of the traction rope and at least one fracturing expansion bag 30 close to the free end of the traction rope must be opposite to the rupture hole.

[0063] It should be noted that in this embodiment, the rotatable traction guide wheel sequentially places multiple fracturing expansion bags 30 into multiple blast holes, with each blast hole corresponding to one or more fracturing expansion bags 30. The length and thickness of the fracturing expansion bags 30 are matched with the depth and diameter of the blast holes to ensure that the fracturing expansion bags 30 can be placed into the blast holes. The number of fracturing expansion bags 30 to be placed in each blast hole depends on the actual needs on site. After the required number of fracturing expansion bags 30 are placed in a blast hole, the traction rope at the corresponding position can be cut. Since the traction guide wheel is at a certain height from the ground or the blast hole, after the traction rope is cut, at least one fracturing expansion bag 30 will remain at the front end of the traction guide wheel, having passed the highest point of the traction guide wheel. This fracturing expansion bag 30 will be in a vertical state under the action of gravity. Since the rupture holes are arranged in a relatively scattered and unordered manner, each time a rupture hole is filled, it is necessary to move the mobile vehicle 10 to adjust the position of the delivery device 20 relative to the rupture hole so that the rupture expansion bag 30 is opposite to the corresponding rupture hole, that is, directly above it.

[0064] It should be noted that the other end of the traction rope needs to be fixed to the vehicle body 11. During deployment, the number of fracturing expansion bags 30 on the traction rope will gradually decrease. When only a few remain, if the other end of the traction rope is not fixed, the remaining fracturing expansion bags 30 will uncontrollably fall into a single burst hole due to gravity and inertia. To prevent this from happening, the other end of the traction rope needs to be fixed. At this point, the length from the fixed position of the traction rope to the end of the last fracturing expansion bag 30 furthest from the burst hole ensures that the last fracturing expansion bag 30 can completely pass the highest point of the traction guide wheel and remain in a vertical position.

[0065] For example, the traction guide wheel in this embodiment is generally triangular, and includes two oppositely arranged support plates and multiple support columns; in other words, the support plates can be triangular plates, with two triangular plates arranged opposite each other and supported by multiple support columns. The multiple support columns are spaced apart along the circumference of the triangular plates and located at the edges to form a winding space between the two support plates and each support column.

[0066] It is understood that the shape of the traction guide wheel is not limited to a triangle, but can be other shapes, and this embodiment does not limit this. Preferably, the traction guide wheel is triangular in shape so that part of the traction rope is located outside the traction guide wheel and remains vertical. The support column can be a hollow column with an opening groove on its outer circumferential surface. The snap-fit ​​structure at the end of the traction rope and the traction rope between the two fracturing expansion bags 30 can be snapped into the opening groove. When the traction guide wheel starts working, the end of the traction rope is wrapped around the support column of the traction guide wheel, and the snap-fit ​​structure at the end of the traction rope snaps into the opening groove of the support column to ensure that part of the traction rope is always located in the opening groove during the operation of the traction guide wheel, so as to ensure that the traction rope and the fracturing expansion bag 30 are located within the winding space. A rotating mechanism is provided at the center of the support plate, through which the traction guide wheel can be rotatably connected to the front end of the mobile vehicle 10.

[0067] Understandably, to ensure that the end of the traction rope is vertical after passing the highest point of the traction guide wheel when the traction guide wheel starts working, a counterweight structure can be set at the end of the traction rope to facilitate the alignment of the end of the traction rope with the blast hole.

[0068] Based on the above embodiments, the mobile vehicle 10 includes a vehicle body 11, and a mounting groove is provided at the front end of the vehicle body 11. The opening of the mounting groove extends to the outer side of the front end of the vehicle body 11. The traction guide wheel is rotatably connected to the mounting groove through a rotating structure and rotates relative to the vehicle body 11.

[0069] It is understood that the rotating mechanism may include a rotating component and a power drive component. For example, the rotating component may be a shaft and a gear, and the power drive component may be a common drive mechanism. A shaft is provided in the mounting slot, and the traction guide wheel is rotatably connected to the vehicle body 11 through the shaft. The motor drives the gear to rotate and drives the shaft to rotate.

[0070] Based on this embodiment, in another embodiment of this application, the number of traction guide wheels is three, respectively located at the front end, left end, and right end of the vehicle body 11; the number of medium boxes is also three, located near the traction guide wheels, respectively located at the rear end of the traction guide wheels along the traction direction of the fracturing expansion bag 30. For example, if the traction guide wheel is located on the left side of the vehicle body 11, the traction direction of the fracturing expansion bag 30 is a right-to-left direction perpendicular to the X-axis, and the medium box corresponding to the traction guide wheel on the left side is located at the rear end of the traction guide wheel along this traction direction. The conveying devices are also set to three, and the conveying devices are located at one end of the blast hole near the traction guide wheel; the sand boxes 40 can also be set to three, corresponding to the other end of the conveying devices, or there can be one sand box 40 with three discharge ports, simultaneously providing sand to the three conveying devices. Other structures in this embodiment are the same as in the above embodiment.

[0071] Second implementation method In cases where the terrain at the mining site is complex or the blasting location is at a high altitude, making it inconvenient for the intelligent operation robot 100 to approach, the delivery device 20 also includes a lifting mechanism 22, which lifts the required fracturing expansion bag 30 to a high position by hoisting, overcoming obstacles, and delivering the fracturing expansion bag 30 into the blasting hole.

[0072] Accordingly, corresponding to this embodiment, the attachment in the fracturing expansion device is configured as a lifting rope, and the fracturing expansion device may include one or more fracturing expansion bags. When the fracturing expansion bag device includes a fracturing expansion bag 30, one end of the lifting rope can be connected to the lifting mechanism 22, and the other end of the lifting rope can be connected to the fracturing expansion bag 30, that is, the other end of the lifting rope suspends a fracturing expansion bag 30.

[0073] When multiple rupture-inducing expansion bags are connected in series on a single suspension rope of the rupture-inducing expansion device, this situation is the same as the implementation method in which multiple rupture-inducing expansion bags are threaded through the same traction rope. That is, along the extension direction of the rupture-inducing expansion bag, the suspension rope is threaded through both ends of each rupture-inducing expansion bag, and a gap is maintained between two adjacent rupture-inducing expansion bags. This will not be elaborated further here.

[0074] Exemplarily, the delivery device 20 includes a lifting mechanism 22, which can be a winch, a freely rotating robotic arm, an air balloon, a drone, etc. For example, a robotic arm, an air balloon, and a drone can all transfer at least one rupture-inducing expansion bag from inside the medium tank to above the rupture hole. This application embodiment uses a winch as an example for illustration. The winch is located at the front end of the mobile vehicle 10, and can be situated on one side of the traction guide wheel; that is, the mobile vehicle 10 can be equipped with a traction guide wheel and / or a winch.

[0075] The lifting mechanism 22 also includes a positioning frame 21 that cooperates with the winch. The positioning frame 21 is connected to the winch and can rise and fall with it under the action of the winch. The lifting mechanism 22 can also rotate circumferentially to adjust the deployment position. The positioning frame 21 includes an I-shaped frame with multiple positioning holes 211 on each side of the frame. Each positioning hole 211 corresponds to a hoisting rope, and each hoisting rope suspends at least one fracturing expansion bag 30, which can be pre-suspended on the frame. It is understood that the shape of the frame can be determined according to the shape of the pre-set blasting hole on the ground; it can be I-shaped or other shapes.

[0076] For example, when blasting operations are required, the necessary fracturing expansion bag 30 is filled with a combustion-supporting medium in the medium tank. The fracturing expansion bag 30 with the added combustion-supporting medium is then suspended by a rope to the positioning hole 211. Subsequently, a winch moves the positioning frame 21 above the blasting hole to be operated. Each positioning hole 211 corresponds to one blasting hole; the fracturing expansion bag 30 is positioned with its corresponding blasting hole by adjusting the position of the winch.

[0077] Alternatively, one or more fracturing expansion bags 30 can be suspended by ropes from each positioning hole 211. A winch can then transfer the fracturing expansion bags 30 from the positioning frame 21 to the medium tank, and add combustion-supporting medium to the fracturing expansion bags 30. Subsequently, the winch can move the positioning frame 21 above the blast hole to be operated. Each positioning hole 211 can correspond to one blast hole, and the fracturing expansion bag 30 can be positioned with its corresponding blast hole by adjusting the position of the winch.

[0078] Preferably, the multiple positioning holes 211 on the positioning frame 21 are arranged in a regular pattern, and the blasting holes in the working area are also arranged in a regular pattern. Based on the positioning of one positioning hole 211, the positioning of multiple rupture expansion bags 30 can be completed, which can improve the delivery efficiency.

[0079] Based on the above embodiments, the positioning frame 21 of this application embodiment is provided with an infrared alignment device, which is used to align the burst hole corresponding to the ruptured expansion bag 30 to be deployed with the positioning hole 211 in which it is located.

[0080] For example, the infrared alignment device includes a transmitter and a receiver, which are mounted on the positioning frame 21. The transmitter emits a detection beam toward the target position in the area to be worked, and the receiver determines the difference between the target position and the target position based on the reception. The position of the positioning frame 21 is adjusted by a winch to complete the alignment of the target positioning hole 211 with the target blasting hole.

[0081] The delivery device 20 provided in this embodiment further includes a shearing component. The shearing component is disposed at the front end of the mobile vehicle 10 and extends to the rupture hole to shear the attachments, causing at least one rupture-inducing expansion bag near the rupture hole to fall into the rupture hole. It is understood that regardless of the implementation of the delivery device 20, the shearing component must cut the suspension rope or traction rope containing the rupture-inducing expansion bag 30 to separate at least one rupture-inducing expansion bag 30 from the suspension rope or traction rope and allow it to fall into the corresponding rupture hole. The number of shearing components can be set according to the number of delivery devices 20.

[0082] For example, when multiple fracturing expansion bags are threaded onto the same traction rope, the bags to be deployed are positioned vertically above and opposite the blast hole under gravity. Assuming there are two fracturing expansion bags corresponding to the blast hole, the traction rope can be cut between the third and second fracturing expansion bags closest to the blast hole, allowing the two bags closest to the blast hole to fall into the hole.

[0083] Furthermore, in this embodiment, the shearing assembly includes a slide and scissors. The slide is slidably mounted on the front end of the mobile vehicle 10, and the scissors are disposed on the slide. The sliding direction of the slide can be set as needed to avoid interference with the traction guide wheel or positioning frame 21. The slide can drive the scissors to move towards or away from the blast hole, and position the scissors above the blast hole. That is, when the deployment operation is completed, the scissors can extend and cut the hoisting rope or traction rope. After cutting, the slide can move in the opposite direction and return to its original position. It is understood that the shearing assembly can be pneumatic scissors, and this embodiment does not limit this.

[0084] Based on the above embodiments, the intelligent operation robot 100 further includes a detonation wire and at least one automatic ignition device connected in series with the detonation wire. The automatic ignition device can be an electronic match. The automatic ignition device is installed in each blast hole to detonate the fracturing expansion bag placed in that blast hole. The automatic ignition device is signal-connected to the control module via the detonation wire. That is, a single signal from the control module initiates the ignition and detonation of the fracturing expansion bag 30 in each blast hole.

[0085] Understandably, the intelligent operation robot 100 is also equipped with a detonator, which is signal-connected to the control module and connected to an automatic ignition device via a detonation wire. Furthermore, the control module can communicate with a remote control center, allowing the remote control center to issue commands and activate the detonator. This enhances the safety of blasting operations.

[0086] It is important to note that before the intelligent operation robot 100 deploys the fracturing expansion bag 30, the automatic ignition device must be placed into the blast hole and the detonation wire connected. Since the detonation wire is generally long enough to allow the intelligent operation robot to move away from the work site, it can be connected to the detonator on the intelligent operation robot 100. After the fracturing expansion bag 30 is deployed and buried, and the intelligent operation robot 100 moves to a safe position, the remote control center can issue an ignition command. Alternatively, the detonation wire can be left unconnected to the intelligent operation robot, and ignition can be manually initiated using a separately located detonator away from the blasting site.

[0087] To further enhance operational safety, the mobile robot in this embodiment also includes an anti-static device. One end of the anti-static device is electrically connected to the vehicle body 11 of the mobile vehicle 10, and the other end is grounded. For example, a metal grounding wire is provided at the bottom of the vehicle body 11, with one end connected to the vehicle body 11 and the other end grounded. This allows the static electricity generated by the mobile robot to be grounded through the metal grounding wire, thereby improving operational safety.
