Description

Technical Field

[0001] This invention belongs to the field of downhole engineering equipment technology, specifically relating to an integrated shotcrete transport vehicle. Background Technology

[0002] Underground roadway support is a core process for ensuring safe production in mines. Among them, shotcrete support is an important means to ensure the stability of the surrounding rock in the roadway and prevent safety hazards such as roof falls and spalling due to its convenient construction and reliable support effect.

[0003] The core requirements of shotcrete support are the precise ratio of concrete to accelerator and continuous supply. Currently, in underground shotcrete support operations, the shotcrete trolley is the core equipment. Its built-in accelerator storage container is standard equipment provided by the manufacturer. Cement slurry is supplied via cement tanker trucks. During underground shotcrete operations, the cement tanker trucks are loaded with cement slurry and connected to the shotcrete trolley via a delivery pipe. The shotcrete trolley consumes cement slurry and accelerator in a proportional manner. The accelerator container on the shotcrete trolley typically has a capacity of 500L. Actual construction verification shows that this capacity can meet the needs of four cement tanker trucks. Shotcrete trolleys are large and expensive, and usually only one is equipped in a project. When the accelerator on the shotcrete trolley is depleted, it needs to be replenished. In existing technology, replenishing the accelerator requires driving the shotcrete trolley out of the tunnel, and a round trip to refill the shotcrete trolley takes 3 hours. During this time, the cement tanker truck has to wait, severely impacting the efficiency of the shotcrete operation.

[0004] The negative impacts of this traditional supply mode on underground support procedures are as follows: On the one hand, the round-trip process of the shotcrete trolley leaving the mine, replenishing the agent, and returning to the mine is time-consuming. Especially in scenarios where the amount of underground shotcrete work surges and the roof is of a high grade and requires timely support, the roadway is prone to prolonged exposure time and the stability of the surrounding rock decreases, increasing the risk of roof collapse. At the same time, it seriously restricts the progress of support construction and fails to meet the core requirement of "timely support" in the management of the roof of underground mines. On the other hand, the underground working environment is complex, the space is narrow, and the line of sight is limited. Frequent back-and-forth travel of the shotcrete trolley can easily lead to collisions with other underground working equipment, while also increasing the probability of underground traffic congestion. This poses a great threat to the personal safety of construction personnel and the safety of equipment, and violates the relevant requirements for the graded management of safety risks of the roof of underground mines.

[0005] In addition, the existing shotcrete trolleys rely heavily on manual operation for accelerator replenishment, lacking automated control components. This results in low replenishment accuracy and efficiency, as well as high labor intensity. It cannot meet the needs of efficient and precise downhole support construction, nor can it satisfy the requirements of the accuracy of accelerator ratio in shotcrete support on the support quality. Summary of the Invention

[0006] To address the problems of low efficiency in replenishing accelerators, frequent interruptions in support operations, and high safety risks in existing downhole shotcrete support operations, a transport vehicle integrating both cement and accelerator replenishment functions is provided. This vehicle simultaneously replenishes cement slurry and accelerators to ensure continuous operation.

[0007] The technical solution adopted by the present invention to solve the aforementioned problem is as follows: An integrated shotcrete transport vehicle includes a cab, a loading platform connected to the rear of the cab, a cement storage tank located at the rear of the loading platform, and an on-board control system within the cab for controlling the feeding series of actions of the cement storage tank. An accelerator storage tank is located at the front of the loading platform, with a feeding component at the top and a discharge component at the bottom. An assembly is connected to the outer end of the discharge assembly, and the other end of the assembly is connected to a shotcrete adapter module. The shotcrete adapter module is mounted on the shotcrete trolley and provides accelerators for shotcrete operations. An intelligent collaborative control module is also included, comprising a control terminal, a data acquisition terminal, and an execution terminal. The control terminal is integrated into the on-board control system, the data acquisition terminal is located in the shotcrete adapter module and the accelerator storage tank, and the execution terminal is located in the cab, the shotcrete trolley work platform, and the connecting assembly. The control terminal controls the actions of the execution terminal based on data from the data acquisition terminal.

[0008] Compared with the prior art, the present invention employing the above structure has the following advantages: This invention, by adding a large-capacity accelerator storage tank and an intelligent collaborative control module to cement tank trucks, enables simultaneous replenishment of cement slurry and accelerator, effectively solving the industry pain point of a 3-hour round trip for the shotcrete trolley to the wellhead. On-site replenishment takes only 3-5 minutes, completely eliminating operational interruptions and significantly improving support efficiency. Simultaneously, high-precision liquid level monitoring and automatic adjustment of the electromagnetic flow valve ensure accurate and constant mixing ratios, guaranteeing shotcrete quality. The elimination of frequent trolley movement also significantly reduces roadway traffic and collision risks, while two-way audible and visual warnings further reduce the burden of manual monitoring. Furthermore, the corrosion-resistant tank, detachable filter, and quick-connect fittings are designed to adapt to harsh underground working conditions and facilitate maintenance. This invention achieves continuous support, precise replenishment, and operational safety through low-cost modifications, demonstrating significant value for promotion in the mining industry.

[0009] As a preferred option, a further technical solution to the above structure is: The feeding assembly includes a feed pipe fixed to the center of the top of the quick-setting agent storage tank, with the upper end of the feed pipe connected to a collection hopper, and a sealing cover installed on the top of the collection hopper.

[0010] The beneficial effects obtained from the above features are: the structure of the feed assembly in this example is adapted to the design of the ground accelerator replenishment equipment, enabling the accelerator tank to be filled quickly.

[0011] The discharge assembly includes a discharge pipe fixed to the bottom of the accelerator storage tank, a filter screen is installed inside the discharge pipe, and the upper end of the discharge pipe is detachably sealed to the accelerator storage tank.

[0012] The beneficial effects obtained from the above features are: this example can filter impurities in the quick-setting agent, preventing impurities from entering the shotcrete trolley, and the discharge pipe adopts an easy-to-disassemble structure, making the filter screen easy to clean.

[0013] The shotcrete adapter module consists of a temporary storage tank, an automatic conveying pump, a pressure regulating module, and a drain valve. The temporary storage tank contains a quick-setting agent, with a discharge connector at one end and a feed connector at the other. The automatic conveying pump is located inside the temporary storage tank to pressurize it. The pressure regulating module is installed on the surface of the temporary storage tank to regulate the internal pressure. The drain valve is located at the bottom of the temporary storage tank.

[0014] The beneficial effects obtained from the above features are as follows: This example adapts the receiving end of the shotcrete trolley to enable it to be connected to a transport vehicle with an integrated accelerator storage tank at any time to replenish the accelerator.

[0015] The intelligent collaborative control module's acquisition end includes a submersible high-precision level gauge, which is installed inside the accelerator storage tank and the temporary storage tank respectively. It collects the remaining amount data in the accelerator storage tank and the temporary storage tank in real time, and transmits the remaining amount data to the control end for information processing through the vehicle control system.

[0016] The beneficial effects obtained from the above features are: it facilitates the monitoring of consumption in accelerator storage tanks and temporary storage containers.

[0017] The execution end of the intelligent collaborative control module includes an electromagnetic flow valve and an audible and visual alarm. The electromagnetic flow valve is installed on the high-pressure wear-resistant rubber hose, and the control end controls the opening of the electromagnetic flow valve according to the remaining amount data of the temporary storage tank. The audible and visual alarm is installed on the operating platform of the cab and the shotcrete trolley, respectively.

[0021] The accelerator storage tank is made of high-strength, corrosion-resistant alloy material and has a capacity of 800L-1200L.

[0022] The beneficial effects obtained from the above features are: the larger capacity of this example ensures the supply of accelerator to the shotcrete trolley. Attached Figure Description

[0025] The present invention will be further described below with reference to embodiments, which are intended only to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0026] Current construction status: The shotcrete trolley is large and moves slowly, occupying almost the entire cross-section of the tunnel when it moves through the tunnel, and it is not a material moving device in the mine.

[0027] As a concrete material transportation equipment, underground cement tanker trucks adopt multi-vehicle cyclic operation. Their working characteristics are "periodic replenishment of concrete from the well and continuous underground concrete transportation", forming a continuous supply of cement slurry. This is a natural fit with the concrete demand of the shotcrete support process. Existing cement tanker trucks only have the single function of concrete storage and transportation.

[0028] Problem-solving idea: Utilize cement trucks to transport accelerators, thereby achieving continuous replenishment of accelerators for shotcrete trolleys.

[0029] See Figures 1 to 6To realize the above concept, the present invention provides an integrated shotcrete transport vehicle, including a cab 1, a loading platform 2 connected to the rear of the cab 1, a cement storage tank 4 disposed at the rear of the loading platform 2, an on-board control system in the cab 1, the on-board control system being used to control the series of feeding actions of the cement storage tank 4, an accelerator storage tank 3 disposed at the front of the loading platform 2, a feeding component disposed at the top of the accelerator storage tank 3, and a discharging component disposed at the bottom of the accelerator storage tank 3; an assembly is connected to the outer end of the discharging assembly, and the other end of the assembly is connected to a shotcrete adapter module, the shotcrete adapter module being installed on the shotcrete trolley for providing accelerator for shotcrete operations; an intelligent collaborative control module is also provided, which includes a control end, a data acquisition end, and an execution end, the control end being mounted in the on-board control system, the data acquisition end being disposed in the shotcrete adapter module and the accelerator storage tank 3, and the execution end being disposed on the cab 1, the shotcrete trolley work platform, and the connecting assembly, the control end controlling the actions of the execution end according to the data from the data acquisition end.

[0030] The integrated shotcrete transport vehicle provided in this solution includes all the structures of the original cement tanker truck. Based on the original structure, the loading platform 2 is enlarged, and the cement storage tank 4 is moved rearward to provide suitable installation space for the accelerator storage tank 3. The installation space dimensions are approximately 1000mm × 700mm × 700mm. A support frame is installed, and the accelerator storage tank 3 is fixed with bolts. After the modification, this integrated transport vehicle simultaneously completes the tasks of concrete supply and accelerator supply and replenishment, adapting to the coordinated needs of the shotcrete support process. It can provide a continuous supply of cement slurry and accelerator, eliminating the need for the shotcrete trolley to replenish accelerator after leaving the well.

[0031] The outer shell of the quick-setting agent storage tank 3 can be made of high-strength wear-resistant alloy material with good wear and corrosion resistance, and the thickness can be selected as 8mm steel plate to resist downhole dust and impact damage. Optionally, the capacity of the quick-setting agent storage tank 3 is 800L to 1200L, which can meet the needs of about 8 truckloads of cement slurry, making it easier to replenish the quick-setting agent and adapting to the continuous operation requirements of downhole shotcrete support.

[0032] Furthermore, the top of the accelerator storage tank 3 is equipped with a bent pipe 11 that communicates with the atmosphere. The bent pipe 11 vents air when the tank is being fed and introduces air when the tank is being discharged, preventing the vacuum inside the tank from affecting the flow of the accelerator. The bent pipe 11 can be a φ50mm steel pipe.

[0033] Alternatively, the feeding assembly includes a feed pipe 32 fixed to the center of the top of the accelerator storage tank 3, with the upper end of the feed pipe 32 connected to a collection hopper 31, the top of which is equipped with a sealing cap. The feed pipe 32 can be a φ100mm steel pipe. The feeding assembly is compatible with ground-based accelerator replenishment equipment, facilitating rapid addition of accelerator.

[0034] Alternatively, the discharge assembly includes an 80mm discharge pipe 33 fixed to the bottom of the accelerator storage tank 3. A filter screen 34 is installed inside the discharge pipe 33, and the upper end of the discharge pipe 33 is detachably and sealed to the accelerator storage tank 3. The filter screen 34 is used to filter out impurities in the accelerator, and this structure facilitates periodic disassembly of the discharge pipe 33 for cleaning of the filter screen 34.

[0035] The connecting assembly uses a high-pressure wear-resistant rubber hose 5 to achieve efficient delivery of the quick-setting agent, adapting to the space constraints of downhole support operations. The high-pressure wear-resistant rubber hose 5 is equipped with quick connectors 10 at both ends. The quick connectors 10 adopt a leak-proof sealing structure to ensure the sealing of the connection in complex downhole environments, avoiding environmental pollution and material waste caused by quick-setting agent leakage. At the same time, it facilitates quick connection and disassembly, shortens the replenishment operation time, and adapts to the efficient advancement requirements of the support process.

[0036] Alternatively, the shotcrete adapter module consists of a temporary storage tank 6, an automatic conveying pump 7, a pressure regulating module, and a drain valve 8. The temporary storage tank 6 contains a quick-setting agent. One end of the temporary storage tank 6 is equipped with a discharge connector, and the other end is equipped with a feed connector. The discharge connector is connected to the additive discharge nozzle of the shotcrete trolley through a conveying pipe, and the feed connector is used to connect to the high-pressure wear-resistant hose 5. The automatic conveying pump 7 is located inside the temporary storage tank 6 and is used to pressurize the temporary storage tank 6. The pressure regulating module is installed on the surface of the temporary storage tank 6 and is used to regulate the internal pressure of the temporary storage tank 6. The drain valve 8 is located at the lower end of the temporary storage tank 6.

[0037] The temporary storage box 6 can be a simple accelerator container that comes with the shotcrete trolley; the automatic delivery pump 7 is made of corrosion-resistant and wear-resistant material and has automatic start-stop and adjustable flow function. Together with the intelligent collaborative control module, it can achieve precise delivery of accelerator; the pressure regulating module is used to stabilize the delivery pressure and avoid excessive pressure causing pipeline damage or excessive pressure affecting the replenishment efficiency; the sewage discharge component is set at the bottom of the module to discharge internal impurities and residual liquid, ensuring the cleanliness of the module and preventing impurities from affecting the accuracy of the accelerator ratio, thereby ensuring the quality of shotcrete support.

[0038] The intelligent collaborative control module's acquisition end includes a submersible high-precision level gauge, which is installed inside the accelerator storage tank 3 and the temporary storage tank 6 respectively. It collects the remaining amount data in the accelerator storage tank 3 and the temporary storage tank 6 in real time, and transmits the remaining amount data to the control end for information processing through the vehicle control system.

[0039] The execution end of the intelligent collaborative control module includes an electromagnetic flow valve 9 and an audible and visual alarm. The electromagnetic flow valve 9 is installed on the high-pressure wear-resistant hose 5. The electromagnetic flow valve 9 accurately monitors the replenishment flow of the accelerator, and the flow data is fed back to the control end. The control end controls the opening of the electromagnetic flow valve 9 based on the remaining amount in the temporary storage tank 6. The audible and visual alarms are installed in the cab 1 and the operating platform of the shotcrete trolley, respectively. When the remaining amount of accelerator in the temporary storage tank 6 is lower than the preset threshold, the control end controls the audible and visual alarms to issue a replenishment reminder to the driver and send a signal to the shotcrete trolley operator to remind them to replenish the accelerator in time, coordinate the work rhythm of both, and ensure the continuous progress of the support process.

[0040] See Figure 6 The optimized workflow using the integrated shotcrete transport vehicle described above is as follows. When this integrated transport vehicle replenishes concrete after leaving the well, it simultaneously adds accelerator through the accelerator storage tank 3. After the addition is completed, the sealing cover is closed. At this time, the liquid level monitoring unit of the intelligent collaborative control module collects the liquid level data of the accelerator storage tank 3, confirms that the accelerator storage capacity meets the continuous replenishment requirements of the downhole shotcrete support process, and feeds back the liquid level data to the vehicle control system (control terminal).

[0041] The integrated transport vehicle, carrying sufficient concrete and quick-setting agent, enters the underground working area. First, it completes the concrete delivery operation at the tunneling face according to the support procedure requirements. Simultaneously, it observes the prompt signals from the intelligent collaborative control module, coordinates the progress of the shotcrete support procedure, and achieves the coordinated advancement of concrete delivery and shotcrete support.

[0042] When the remaining amount of quick-setting agent in the shotcrete adapter module is lower than the preset threshold, the intelligent collaborative control module issues an audible and visual prompt, and the shotcrete trolley operator suspends the shotcrete operation (without moving the shotcrete trolley). The driver of the integrated transport vehicle drives to the vicinity of the shotcrete trolley's operating position, keeping a reasonable distance between the two (ensuring that the high-pressure wear-resistant hose 5 can be connected normally), adapting to the operating requirements of narrow spaces downhole.

[0043] The operator connects one end of the high-pressure wear-resistant hose 5 to the feed connector of the shotcrete adapter module via the quick connector 10. After connection, the operator sets the replenishment flow rate and replenishment amount through the intelligent collaborative control module, starts the automatic delivery pump 7, and draws the accelerator from the accelerator storage tank 3. The accelerator is then delivered to the shotcrete adapter module via the high-pressure wear-resistant hose 5 and the electromagnetic flow valve 9. The electromagnetic flow valve 9 measures the replenishment amount in real time. When the preset replenishment amount is reached, the automatic delivery pump 7 automatically stops, the electromagnetic flow valve 9 is closed, and the quick connector 10 is disconnected to complete one replenishment operation. The entire process takes only 3-5 minutes, quickly restoring the shotcrete support operation and avoiding process interruption.

[0044] The shotcrete adapter module delivers the accelerator to the shotcrete system of the shotcrete trolley according to a precise ratio. After mixing with the concrete, the shotcrete support operation is completed. The intelligent collaborative control module monitors the accuracy of the accelerator ratio in real time to ensure that the support quality meets the support requirements of the roof. When the accelerator liquid level in the accelerator storage tank 3 is lower than the preset value, the intelligent collaborative control module sends a warning signal to the driver of the integrated transport vehicle, reminding him to replenish the accelerator at the same time when replenishing concrete during the next well run.

[0045] Regularly clean and maintain the cleaning port of the quick-setting agent storage tank 3 and the sewage outlet of the shotcrete adapter module to remove residual quick-setting agent and impurities, ensure normal operation of the equipment, and guarantee the continuous and stable progress of the support process. At the same time, the capacity and replenishment flow of the quick-setting agent storage tank 3 can be adjusted according to the changes in the underground roof grade and the amount of shotcrete work to meet the needs of different support scenarios.

[0046] The beneficial effects of this invention are: I. Eliminating Operational Interruptions and Significantly Improving Construction Efficiency. This invention integrates a large-capacity accelerator storage tank onto a cement truck, enabling simultaneous replenishment of cement slurry and accelerator in a single truck. This fundamentally solves the pain point of the shotcrete rig taking 3 hours to travel to and from the wellhead to replenish the accelerator. The integrated transport vehicle provided by this invention can be rotated 3-4 times per week to replenish the shotcrete rig with the accelerator. Each replenishment takes only 3-5 minutes and is carried out simultaneously with the cement supply from the transport vehicle to the shotcrete rig, eliminating the need to move the rig and ensuring continuous shotcrete operations, thus meeting the safety requirements of "timely support" in mines.

[0047] II. Achieving precise automatic control and ensuring support quality. The intelligent collaborative control module constructed in this invention monitors the remaining liquid level in real time through a high-precision level gauge, ensuring a continuous supply of accelerator, and significantly improving the strength and stability of the shotcrete support layer.

[0048] Third, it reduces safety risks and labor intensity. This invention avoids the shotcrete trolley from frequently traveling back and forth in narrow alleys, significantly reducing the probability of equipment collisions and traffic accidents. At the same time, the two-way warning function of the audible and visual alarm coordinates the work rhythm of the driver and operator, reducing the burden of manually monitoring the remaining material.

[0049] IV. Reasonable Structure and Strong Adaptability. The quick-setting agent storage tank is made of corrosion-resistant alloy material and equipped with a removable filter and quick connectors for easy maintenance, making it suitable for harsh underground working conditions. This invention breaks through a long-standing efficiency bottleneck with relatively low modification costs and has broad application value in the field of mine support.
