Description

Technical Field

[0001] This invention relates to the field of mining material transportation technology, specifically to a rail-guided bulk material transport tanker and transportation system for mining. Background Technology

[0002] Backfilling mining refers to a mining method that involves filling the goaf with backfill material while simultaneously carrying out ore extraction, transportation, and other operations. However, as underground mining projects progress to deeper areas, underground backfilling mixing plants offer unique advantages compared to surface backfilling mixing plants. The three raw materials used in backfilling mixing plants are mortar, water, and cementitious materials. Typically, whole or graded tailings are mixed with a certain proportion of cementitious materials and water to create a highly concentrated or paste-like material for backfilling into the goaf. Mortar and water can be transported underground via pipelines, while cementitious materials are generally transported by bulk transport tankers. While many mining areas have rail transport systems, there are currently no suitable rail-mounted bulk transport tankers for underground use, unlike the small trackless cement tankers used for trackless transport.

[0003] Therefore, for mines where rail transport is the auxiliary mode of transportation, it is necessary to design and manufacture a tanker truck with underground rail bulk material transport function to solve the problem of transporting cementitious materials. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a rail-guided bulk material transport tanker that is suitable for rail transport working environments. Multiple transport tankers can be grouped together, and a tractor can simultaneously tow multiple transport tankers, thereby increasing the material transport capacity per trip.

[0006] The embodiments of the present invention provide a rail-guided bulk material transport system for mining.

[0007] The mining rail-mounted bulk material transport tanker of this invention includes a rail chassis suspension assembly, a tank body, an air inlet pipe, a discharge pipe, and a sealing cover. The rail chassis suspension assembly is used to travel on a rail. The tank body is mounted on the rail chassis suspension assembly and has a storage cavity. The tank body is provided with a loading port. The air inlet pipe is located at one end of the tank body in a first direction and communicates with the storage cavity. The discharge pipe is located at the other end of the tank body in the first direction and communicates with the storage cavity. The sealing cover is located at the loading port.

[0008] The mining rail bulk material transport tanker of this invention is suitable for rail transport working environments. Multiple transport tankers can be grouped together, and a tractor can simultaneously tow multiple transport tankers, thereby increasing the material transport capacity per trip.

[0009] In some embodiments, the mining rail-guided bulk material transport tanker further includes an activated gas supply pipeline and multiple flow-aiding air cushions. The activated gas supply pipeline is located at the other end of the tank body and is used to connect to a gas delivery system. Multiple flow-aiding air cushions are provided on the activated gas supply pipeline and are located within the storage cavity. After airflow is introduced into the activated gas supply pipeline, the flow-aiding air cushions generate high-frequency vibrations, activating, cleaning, and transporting the agglomerated gel material.

[0010] In some embodiments, the activated gas delivery pipeline is arranged along the bottom wall surface adjacent to the storage cavity, and the flow-aiding air cushion is located on the bottom wall surface of the storage cavity. Cement caking is prone to occur on the bottom wall surface of the storage cavity. Placing the flow-aiding air cushion on the bottom wall surface of the storage cavity improves the activation treatment effect on caking cement.

[0011] In some embodiments, the discharge pipe is located in the middle of the tank's extension direction, and the tank's extension direction is perpendicular to the first direction.

[0012] In some embodiments, the activation gas supply pipeline includes a first inclined section, a connecting section, and a second inclined section. The first inclined section, the connecting section, and the second inclined section are sequentially connected. The first inclined section is used to connect to the gas supply system. Both the first and second inclined sections are provided with the flow-aiding air cushions. The connecting section is adjacent to the discharge pipeline in the first direction. The ends of the first and second inclined sections opposite to the connecting section are spaced apart from the connecting section in the first direction. The first and second inclined sections are inclined pipeline sections. Multiple flow-aiding air cushions are provided on the first and second inclined sections, forming a staggered arrangement of the flow-aiding air cushions. Furthermore, both the first and second inclined sections are inclined towards the connecting end (i.e., the discharge pipeline), which conforms to the overall flow direction when the gel material is discharged. When gas is introduced into the activation gas supply pipeline 6 to drive the multiple flow-aiding air cushions to vibrate at high frequency, it can effectively prevent cement material from caking and the activation effect after caking.

[0013] In some embodiments, the activated gas supply line further includes an activated gas inlet valve, which is disposed on the first inclined section.

[0014] In some embodiments, the mining rail-guided bulk material transport tanker further includes a ladder, with its two ends in the first direction located at one end and the other end of the tank body, respectively.

[0015] In some embodiments, the mining rail-mounted bulk material transport tanker further includes a flange blind plate, and the tank body is provided with an inspection port, with the flange blind plate disposed at the inspection port.

[0016] In some embodiments, the mining rail-mounted bulk material transport tanker further includes a safety valve, which is provided on both the discharge pipeline and the air inlet pipeline.

[0017] In some embodiments, the mining rail-mounted bulk material transport tanker further includes a pressure gauge disposed on the tank body to monitor the pressure within the storage cavity.

[0018] In some embodiments, safety latches are provided at both ends of the rail chassis suspension assembly.

[0019] The mining rail bulk material transport system of this invention includes a tractor and a mining rail bulk material transport tank car, wherein the tractor is connected to the mining rail bulk material transport tank car.

[0020] The mining rail bulk material transport system of this invention can group multiple transport tank cars together, and the tractor can pull multiple transport tank cars at the same time, thereby increasing the material transport capacity per trip. Attached Figure Description

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] The following is a reference to the appendix. Figures 1 to 2 This invention provides a detailed description of the mining rail-guided bulk material transport tanker 100 and its transport system, according to embodiments of the present invention.

[0027] An embodiment of the present invention provides a mining rail bulk material transport system including a tractor (not shown in the figure) and a transport tanker 100, wherein the tractor is connected to the mining rail bulk material transport tanker 100.

[0028] The mining rail-mounted bulk material transport tanker 100 of this invention includes a rail chassis suspension assembly 1, a tank body 2, an air inlet pipe 3, and a discharge pipe 4. The rail chassis suspension assembly 1 is used to travel on a rail. The tank body 2 is mounted on the rail chassis suspension assembly 1, and the tank body 2 has a storage cavity and a loading port. The air inlet pipe 3 is located in a first direction (e.g., in the direction of the tank body 2). Figure 1 At one end of the tank 2 (in the vertical direction shown), the air inlet pipe 3 is connected to the storage cavity. The discharge pipe 4 is located at the other end of the tank 2 in this first direction and is connected to the storage cavity. The sealing cover 5 is located at the loading port.

[0029] like Figure 1 As shown, in the usage state, the first direction of the mine rail-guided bulk material transport tanker 100 of this embodiment is the same as the up-down direction. The air inlet pipe 3 is located at one end of the tank body 2 in this first direction, that is, the air inlet pipe 3 is located at the upper end of the tank body 2. The discharge pipe 4 is located at the other end of the tank body 2 in this first direction, that is, the discharge pipe 4 is located at the lower end of the tank body 2. According to... Figure 1 As shown, tank 2 extends in the left-right direction.

[0030] In use, the mining rail-guided bulk material transport tanker 100 of this embodiment is pulled to the lower opening of the cementitious material silo by a tractor (e.g., an electric locomotive or a diesel locomotive). The tractor has an automatic positioning function. After the tractor reaches the set position, the cementitious material silo receives the loading positioning signal and opens the sealing cover 5. At this time, the bulk loading machine at the lower opening of the cementitious material silo starts. The feeding funnel of the bulk loading machine is aligned with the loading port of the tank 2 and quantitatively loads the material into the storage cavity. After loading is completed, the sealing cover 5 is closed, compacted, and bolted.

[0031] The tractor pulls the fully loaded transport tanker 100 along the designed track to the underground filling and mixing station. After the tractor reaches the unloading positioning point, the unloading process begins. First, the discharge pipe 4 of the transport tanker 100 is connected to the feed pipe of the cementitious material silo of the mixing station, and the air inlet pipe 3 of the tank 2 is connected to the external high-pressure air pipe. After the pipe connections are completed, a unloading execution signal is sent to the mixing station, the high-pressure air is activated, and high-pressure air is delivered into the storage cavity. Under the action of the high-pressure air, the material in the storage cavity is transported to the cementitious material silo of the mixing station. After the material in the tank 2 is discharged, the discharge pipe 4 is disconnected from the feed pipe, and the air inlet pipe 3 is disconnected from the external high-pressure air pipe, completing the unloading operation.

[0032] Therefore, the mine rail bulk material transport tanker 100 of this embodiment can be applied to rail transport working environments.

[0033] To make the solution of this application easier to understand, an example will be given where the first direction is the same as the up-down direction and the extension direction of the tank 2 is the same as the left-right direction. The up-down direction is as follows: Figure 1 As shown, the left and right directions are as follows Figure 1 As shown.

[0034] The mining rail-mounted bulk material transport tanker 100 of this invention includes a rail chassis suspension assembly 1, a tank body 2, an air inlet pipe 3, a discharge pipe 4, a pressure gauge 10, a flange blind plate 11, a ladder 8, an activated air supply pipe 6, and multiple flow-aiding air cushions 7.

[0035] The rail-mounted chassis suspension assembly 1 is used for traveling on rails.

[0036] Specifically, the rail chassis suspension assembly 1 includes a frame, a suspension system, and wheel sets. The frame, as the load-bearing foundation of the entire rail chassis suspension assembly 1, connects the suspension system, wheel sets, and tank 2, and is the core structure for load bearing and force transmission. The suspension system mitigates the impact and vibration caused by uneven track surfaces, improves cargo safety, and protects vehicle components from excessive fatigue damage. The wheel sets support the transport tank 100 and enable it to roll along the track.

[0037] Specifically, safety latches are provided at both ends of the rail chassis suspension assembly 1. These safety latches are used to connect with the tractor or adjacent tank cars 100. In other words, one tractor can tow multiple tank cars 100 according to this embodiment of the invention; the tractor and tank cars 100 are connected via safety latches, and adjacent tank cars are connected via safety latches.

[0038] Specifically, the rail chassis suspension assembly 1 in this embodiment is adapted to narrow rail transportation, wherein the gauge of the narrow rail is 900mm or 600mm.

[0039] like Figure 1 In the embodiment shown, the dimensions of the track chassis suspension assembly 1 are: 3m long × 1.50m wide × 1.50m high.

[0040] The tank body 2 is mounted on the track chassis suspension assembly 1, and the tank body 2 has a storage cavity. In this embodiment, the effective volume of the storage cavity of the tank body 2 is 5m³.

[0041] Tank 2 is made of alloy steel and is welded from alloy steel. After the tank 2 is manufactured, it needs to undergo a pressure test. After the pressure test is passed, it can be put into use for material storage.

[0042] The tank body 2 is provided with a loading port. In this embodiment, as shown... Figure 1 As shown, there are four loading ports, all located at the top of the tank body 2, and the four loading ports are arranged at equal intervals along the left and right directions.

[0043] The sealing cover 5 is located at the loading port.

[0044] Specifically, the sealing cover 5 is a pin-and-pillar type cover that can open 180°. After the sealing cover 5 is opened, the loading port is open, and the storage cavity is opened to fill the storage cavity with materials. After filling is completed, the sealing cover 5 is closed and compacted, and the sealing cover 5 and the tank body 2 are fixed with bolts.

[0045] An air inlet pipe 3 is located at one end (upper end) of the tank body 2 in the first direction, and the air inlet pipe 3 is connected to the storage cavity. A safety valve 9 is provided on the air inlet pipe 3. The safety valve 9 on the air inlet pipe 3 is normally closed. When the gas pressure in the storage cavity exceeds the set pressure, the safety valve 9 on the air inlet pipe 3 opens to release the pressure.

[0046] Specifically, the air inlet pipe 3 is a seamless galvanized steel pipe for low-pressure fluid transportation, and the air inlet pipe 3 is located on the right side of the tank body 2.

[0047] The discharge pipe 4 is located at the other end of the tank body 2 in the first direction, and the discharge pipe 4 is connected to the storage cavity.

[0048] Specifically, the discharge pipeline 4 uses a seamless galvanized steel pipe for low-pressure fluid transportation.

[0049] A safety valve 9 is installed on the discharge pipeline 4. The safety valve 9 on the discharge pipeline 4 is normally closed. When the pressure in the discharge pipeline 4 exceeds the set pressure, the safety valve 9 on the discharge pipeline 4 opens to release the pressure.

[0050] In some embodiments, a pressure gauge 10 is provided on the tank 2 to monitor the pressure inside the storage cavity.

[0051] Specifically, there are multiple pressure gauges 10, with pressure gauges 10 installed on both the left and right sides of the tank 2. The pressure gauges 10 are used to monitor the gas pressure inside the tank 2.

[0052] Specifically, the discharge pipe 4 is located in the middle of the extension direction of the tank body 2, and the extension direction of the tank body 2 is perpendicular to the first direction.

[0053] In some embodiments, the tank 2 is provided with an inspection port, and a flange blind plate 11 is provided at the inspection port. When the tank 2 needs to be maintained, personnel can enter and exit the tank 2 through the inspection port.

[0054] Specifically, there are three inspection ports, which are evenly arranged along the left and right sides of tank body 2, such as... Figure 1 As shown, inspection ports are provided on the left and right sides and the middle of the upper end of tank 2.

[0055] In some embodiments, the two ends of the ladder 8 in the first direction are located at one end (upper end) and the other end (lower end) of the tank 2, respectively. The ladder 8 is used for pedestrian access during equipment maintenance.

[0056] Specifically, ladder 8 is made of metal.

[0057] In some embodiments, the activated gas supply line 6 is located at the other end (lower end) of the tank 2. The activated gas supply line 6 is used to connect to the gas supply system. The activated gas supply line 6 is provided with a plurality of flow-aiding air cushions 7, which are located inside the storage cavity.

[0058] That is, the activation gas supply line 6 is located at the lower end of the tank 2, and the flow-aiding air cushion 7 is located at the lower end of the storage cavity. When it is found that the gel material (such as cement) is difficult to feed and transport in the tank 2, the activation gas supply line 6 is connected to an external gas supply system. The gas supply system supplies gas to the activation gas supply line 6, and the airflow enters the flow-aiding air cushion 7 through the pipeline. The flow-aiding air cushion 7 generates high-frequency vibration to activate, clean, and transport the gel material that has clumped or hardened.

[0059] Furthermore, the activated gas supply line 6 is arranged along the bottom wall of the adjacent storage cavity, and the flow-aiding air cushion 7 is located on the bottom wall of the storage cavity. Cement caking is prone to occur on the bottom wall of the storage cavity. Placing the flow-aiding air cushion 7 on the bottom wall of the storage cavity improves the activation treatment effect on the caking cement.

[0060] The activated gas supply pipeline 6 includes a first inclined section 61, a connecting section 62, and a second inclined section 63. The first inclined section 61, the connecting section 62, and the second inclined section 63 are connected in sequence. The first inclined section 61 is used to connect to the gas supply system. Both the first inclined section 61 and the second inclined section 63 are provided with flow-aiding air cushions 7. The connecting section 62 is adjacent to the discharge pipeline 4 in the first direction. The end of the first inclined section 61 facing away from the connecting section 62 (left end) and the end of the second inclined section 63 facing away from the connecting section 62 (right end) are both spaced apart from the connecting section 62 in the first direction.

[0061] like Figure 1 As shown, the connecting section 62 is located in the middle of the tank body 2 in its extending direction. The connecting section 62 is located at the lower end of the tank body 2. The left end of the first inclined section 61 is high and the right end is low. The left end of the second inclined section 63 is low and the right end is high.

[0062] The first inclined section 61 and the second inclined section 63 are inclined pipe sections. Multiple flow-aiding air cushions 7 are set on the first inclined section 61 and the second inclined section 63 to form an alternating arrangement of the flow-aiding air cushions 7 at different heights. Furthermore, the first inclined section 61 and the second inclined section 63 are both inclined towards the connection end (i.e., the discharge pipe 4), which conforms to the overall flow direction when the gel material is discharged. When gas is introduced into the activation gas supply pipe 6 to drive the multiple flow-aiding air cushions 7 to vibrate at high frequency, it can effectively prevent cement material from caking and the activation effect after caking.

[0063] Specifically, two air cushions 7 are provided on the first inclined section 61 and two air cushions 7 are provided on the second inclined section 63.

[0064] Specifically, such as Figure 2 As shown, the first inclined section 61 and the second inclined section 63 are both installed on the tank body 2 through the mounting plate 12. The first inclined section 61 and the second inclined section 63 are both provided with connecting pipes 65, which are connected to the flow-aiding air cushion 7.

[0065] Specifically, the activated gas supply line 6 further includes an activated gas inlet valve 64, which is located on the first inclined section 61. The inlet valve 64 is opened when gas needs to be supplied to the activated gas supply line 6. The inlet valve 64 is closed after activation is complete.

[0066] Therefore, the mine rail-guided bulk material transport tanker 100 of this invention realizes the transportation of cementitious materials for underground rail transport. Compared with underground vehicle-mounted transport tankers, the transport tanker 100 of this invention has the following advantages: the transport tankers 100 can be grouped, and a tractor can simultaneously tow multiple transport tankers 100, increasing the material transport capacity per trip; the required roadway cross-section is small, and it can share existing rail facilities with underground rail transport vehicles, saving investment; rail transport is safer. In addition, compared with the pipeline transport of bulk materials in related technologies, the transport tanker 100 of this invention has a longer transport distance, is not affected by the maximum transport distance of the pipeline power unit, and has no risk of pipe blockage.

[0067] The mine rail-mounted bulk material transport tanker 100 of this invention can be manufactured to be relatively small and flexible. It does not require a compressed air power unit and can adapt to underground transportation conditions, greatly facilitating equipment transportation, installation, inspection and maintenance. The tank body 2 is equipped with a pressure gauge 10, and safety valves 9 are installed on both the discharge pipe 4 and the air inlet pipe 3 to realize high pressure alarm and ensure that the device operates in a safe environment.
