Description

Technical Field

[0001] This invention relates to the field of coal mining technology, specifically to an explosion-proof diesel engine tracked support transport vehicle. Background Technology

[0002] As a key piece of equipment in the face relocation process of fully mechanized coal mining faces, the technology of support transport vehicles has evolved from simple to complex, and from single-function to multi-function. Early support transport vehicles were mainly wheeled, with low load capacity and poor adaptability, making them unsuitable for complex working conditions. With the continuous expansion of coal mining depth and scale, the performance requirements for support transport vehicles have gradually increased, driving breakthroughs and innovations in related technologies. For example, based on the WC40Y frame-type support transport vehicle, the Taiyuan Research Institute successively developed a series of models such as the WC50Y, WC55Y, and WC60Y, achieving a leap in load capacity from 30 tons to 100 tons. Localized improvements were made for the operating conditions of Chinese coal mines, significantly improving the reliability and applicability of the equipment. With the rapid development of explosion-proof diesel engine technology, hydraulic transmission technology, and intelligent control technology, the functions of support transport vehicles have been further improved. Especially with breakthroughs in key technologies such as high-power explosion-proof diesel engines, wet brake wheel-side reducers, and open load lifting systems with sprockets and circular chains, domestically produced support transport vehicles have gradually broken free from dependence on imported equipment, and some technologies have reached international leading levels.

[0003] Traditional wheeled support transport vehicles have poor maneuverability when traveling on complex and rugged surfaces (such as muddy, raised, and sunken surfaces) in underground coal mines, making them prone to slipping and getting stuck, which affects the efficiency of support transport. Moreover, wheeled support transport vehicles typically have a climbing ability of around 15°. In directional coal seams, they face traction and stability issues, while in directional coal seams, the steep slope and complex terrain exacerbate braking, steering, and structural adaptability deficiencies. Meanwhile, rail-mounted transport vehicles are highly dependent on rails and have poor flexibility. Shovel-type support transport vehicles have a large overall length and width due to their shovel structure, which limits their turning radius and makes it difficult to adjust direction flexibly in narrow or winding tunnels, requiring frequent reversing or route adjustments, thus reducing transport efficiency. Therefore, an explosion-proof diesel engine tracked support transport vehicle is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an explosion-proof diesel-powered tracked support transport vehicle to solve the problems mentioned in the background art. Traditional wheeled support transport vehicles have poor passability when traveling on complex and rugged roads (such as muddy, raised, and sunken roads) in coal mines, and are prone to slipping and getting stuck, which affects the efficiency of support transport. Moreover, wheeled support transport vehicles typically have a climbing ability of about 15°. In directional coal seams, they face traction and stability problems, while in directional coal seams, the large slope and complex terrain exacerbate the defects in braking, steering, and structural adaptability. Meanwhile, rail-mounted transport vehicles are highly dependent on rails and have poor flexibility. Shovel-type support transport vehicles have a large overall length and width due to the shovel structure, which limits the turning radius and makes it difficult to flexibly adjust the direction in narrow or curved roadways, requiring frequent reversing or route adjustments, thus reducing transportation efficiency.

[0008] Preferably, the connecting assembly includes two fixing frames, two fixing shafts, and two connecting seats. The two fixing frames are fixedly connected to the two ends of the bottom side of the mounting groove.

[0014] Compared with the prior art, the present invention, employing the above technical solution, has the following technical effects: 1. This invention adopts a tracked chassis walking structure, which reduces the ground pressure and improves the equipment's passability on muddy and rugged underground roads, avoiding slippage and getting stuck, ensuring continuous and efficient handling operations. Moreover, the wide tracked chassis contact area effectively distributes weight, reduces pressure on the tunnel floor, reduces ground wear and damage, and extends the service life of the tunnel. At the same time, the transport vehicle can turn on the spot through differential speed control of the left and right tracked chassis, greatly reducing the turning radius.

The other end of the second connecting rod then moves one end of the first connecting rod via a rotating shaft. At this time, one end of the first connecting rod causes the connecting arm to descend. After loading is completed, the piston rods of the two hydraulic cylinders extend, causing the piston rods of the two hydraulic cylinders to move and reset the other end of the carrier plate via the second connecting rod, the fixed seat, the rotating shaft, the first connecting rod, and the connecting arm. Then, the piston rods of the four hydraulic limiters are extended. The piston rods of the hydraulic limiters can fix and limit the bracket, preventing the bracket from falling off.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example Please see Figure 1-6 This invention provides a technical solution: an explosion-proof diesel engine tracked support transport vehicle, comprising a load-bearing platform 1, a power module 2, an operating module 3, and a walking module 4. The power module 2 is located at the front end of the load-bearing platform 1, the operating module 3 is located at the front end of the load-bearing platform 1, and the walking module 4 is located on both sides of the load-bearing platform 1. A load-bearing component is located at the rear end of the load-bearing platform 1. The load-bearing platform 1 is used for loading and unloading the support; the power module 2 is used for driving the walking module 4 of the transport vehicle; the operating module 3 is used for driving control of the transport vehicle; and the walking module 4 is used for moving the transport vehicle.

[0023] The support platform facilitates the transportation of the support structure. The support platform 1 includes a carrier plate 15, two sets of hydraulic limiters 16, two fixing seats 17, and a housing 24. One end of the housing 24 has a mounting groove 23. One end of the carrier plate 15 is installed inside the bottom of the mounting groove 23. The two sets of hydraulic limiters 16 are respectively installed on both sides inside the mounting groove 23. When loading the support structure, a wireless remote control controls the piston rods of the four hydraulic limiters 16 to reset and disengage from the top of the carrier plate 15, facilitating subsequent fixation of the support structure. The two fixing seats 17 are respectively fixedly connected to the top end of the housing 24, and both fixing seats 17 are rotatable. A rotating shaft 18 is connected to the support plate 15. One end of each rotating shaft 18 is hinged to a first connecting rod 19, and one end of each first connecting rod 19 is hinged to a connecting arm 20. One end of each connecting arm 20 is fixedly connected to the top of the other end of the carrier plate 15. By moving one end of a second connecting rod 21, the other end of the second connecting rod 21 drives one end of the first connecting rod 19 to move through the rotating shaft 18. At this time, one end of the first connecting rod 19 drives the connecting arm 20 to descend, so that the other end of the carrier plate 15 is adapted to the storage position of the bracket, so as to facilitate the loading of the bracket. An adjustment component is provided on the top of the housing 24, and a connecting component is provided at the bottom of the inner part of the mounting groove 23. The adjustment assembly facilitates the adjustment of the carrier plate 15. The adjustment assembly includes two second connecting rods 21 and two hydraulic cylinders 22. The two second connecting rods 21 are respectively hinged to the other end of the two rotating shafts 18, and the two hydraulic cylinders 22 are hinged to the top of the housing 24. The piston rods of the two hydraulic cylinders 22 are respectively hinged to one end of the two second connecting rods 21. After loading, the piston rods of the two hydraulic cylinders 22 extend, causing the piston rods of the two hydraulic cylinders 22 to drive the other end of the carrier plate 15 to move and reset through the second connecting rods 21, the fixed seat 17, the rotating shaft 18, the first connecting rod 19 and the connecting arm 20. Then, the piston rods of the four hydraulic limiters 16 are controlled to extend. The piston rods of the hydraulic limiters 16 can fix and limit the bracket to prevent the bracket from falling off.

[0024] By setting up a connecting assembly, the carrier plate 15 can be connected and moved. The connecting assembly includes two fixed frames 11, two fixed shafts 13, and two connecting seats 14. The two fixed frames 11 are fixedly connected to the two ends of the bottom inside the mounting groove 23. One end of each of the two connecting seats 14 is installed inside the two fixed frames 11. The two fixed shafts 13 are fixedly inserted through one end of each of the two connecting seats 14. Both sides of the two fixed frames 11 are provided with long through grooves 12. The ends of the two fixed shafts 13 are inserted into the two long through grooves 12. One end of the first connecting rod 19 drives the connecting arm 20 to descend. During this process, the carrier plate 15 drives the fixed shafts 13 on the two connecting seats 14 to slide inside the long through grooves 12. Then the other end of the carrier plate 15 moves and tilts, so that the other end of the carrier plate 15 is adapted to the storage position of the bracket.

[0025] The power module 2 includes an explosion-proof diesel engine body 5, a plunger pump 6, and an exhaust gas treatment box 9. The explosion-proof diesel engine body 5 is installed inside the front of the housing 24. The plunger pump 6 is installed on the explosion-proof diesel engine body 5. A radiator 7 is installed on the end of the explosion-proof diesel engine body 5 away from the plunger pump 6. After the explosion-proof diesel engine body 5 is started, the radiator 7 can provide heat dissipation for the explosion-proof diesel engine body 5. A diesel tank 8 is set below the radiator 7. The explosion-proof diesel engine body 5 starts and burns the diesel in the diesel tank 8 to generate power, which is then transmitted to the plunger pump 6 through the coupling. The hydraulic system is distributed to each load-bearing platform 1 and the traveling module 4 to complete the corresponding actions. The exhaust gas treatment box 9 is installed inside the housing 24. The exhaust gas treatment box 9 can cool and purify the exhaust gas, eliminate sparks, and block the spread of flames, ensuring that the explosion-proof diesel engine body 5 will not ignite the surrounding explosive gases during operation.

[0026] The diesel tank 8 supplies fuel to the diesel engine. It is made of non-flammable materials and kept away from heat sources to prevent danger caused by impact or high temperatures.

[0027] Exhaust gas treatment box 9 is a water-washing type exhaust gas treatment box. Its function is: Cooling: The high-temperature exhaust gas is cooled to below 70°C through water jacketing and water washing to prevent ignition of surrounding gases.

[0028] Purification: The water washing process can remove harmful gases and particulate matter from the exhaust gas, reducing emissions pollution.

[0029] Flame arrestor: The internal structural design prevents the flame inside the cylinder from spreading outward.

[0030] Air intake system: including air filter, air intake flame arrester, etc., used to filter air and prevent flame from coming out of the air intake.

[0031] Exhaust system: including water-cooled exhaust manifold, exhaust pipe, etc., which works in conjunction with the exhaust gas treatment device to ensure exhaust safety.

[0032] Safety protection system: Includes sensors for temperature, pressure, gas concentration, etc., and automatic shutdown device, which immediately shuts down the machine in case of dangerous operating conditions.

[0033] The core design philosophy of this system is "safety first". Through comprehensive control of intake, exhaust, surface temperature and electrical systems, it ensures the reliable operation of diesel engines in high-risk environments.

[0034] Explosion-proof mechanism: both the intake and exhaust systems are equipped with flame arresters to prevent spark leakage; the exhaust gas treatment box 9 cools and removes dust from the exhaust gas to ensure safe emissions; the automatic protection device monitors the exhaust gas temperature, the surface temperature of the explosion-proof diesel engine body 5, the cooling water temperature, water level and oil pressure in real time, and will trigger an audible and visual alarm and shut down the engine if any abnormality is triggered.

[0035] The flame-arresting mechanisms of intake and exhaust flame arresters are mainly based on the theories of "gap extinguishing" and "thermal quenching extinguishing": Thermal quenching: When the flame enters the numerous narrow metal channels inside the flame arrester, the flame is divided into countless tiny flames. These tiny flames come into full contact with the channel walls (metal material), and the heat is rapidly absorbed, causing the temperature to drop sharply below the ignition point of the fuel, thereby stopping the combustion reaction.

[0036] The wall effect: The narrow channel wall captures and consumes the active free radicals generated during combustion, interrupting the chain reaction of combustion and preventing the flame from spreading further.

[0037] The intake and exhaust flame arresters of the explosion-proof diesel engine body 5 consist of the following parts: Stainless steel casing: Made of stainless steel, it can withstand the impact pressure of an explosion and protect the internal components.

[0038] Flame arrestor core (core component): Metal mesh type: It is made of multiple layers of stainless steel mesh, with mesh size usually between 0.23-0.315mm and up to 4-12 layers. The dense mesh achieves fire resistance.

[0039] Corrugated plate type: It is made of stainless steel corrugated plate folded into a labyrinth structure, forming a large number of parallel narrow channels, which has high fire resistance and relatively low airflow resistance.

[0040] Expansion chamber: Installed before and after the flame arrestor core, it is used to buffer the airflow and prevent the flame from directly penetrating the flame arrestor core due to high-speed impact.

[0041] Connection flange: Used for reliable connection to the air filter and engine intake manifold, ensuring airtightness. I. Core Role Cooling exhaust: The high-temperature exhaust gas (above 600°C) discharged from the explosion-proof diesel engine body 5 is cooled to below 70°C through full contact with water, eliminating the high-temperature ignition source.

[0042] Flame suppression and extinguishing: Utilizing the water layer and internal structure, it completely extinguishes any flames and sparks that may be carried in the exhaust, preventing them from spreading outward.

[0043] Purifying exhaust gas: By washing with water, carbon particles, oil fumes, and some harmful gases (such as CO and NOx) in the exhaust gas are removed, reducing environmental pollution.

[0044] Noise reduction: By utilizing internal chambers and water flow, exhaust noise is significantly reduced, improving the working environment in the well.

[0045] The internal structure of the exhaust gas treatment box 9 mainly includes the following key parts: 1. Intake guide pipe It is located at one end of the housing and is connected to the engine exhaust manifold.

[0046] The end is usually designed as a multi-hole nozzle or spiral nozzle to spray high-temperature exhaust gas into water at high speed, increasing the gas-liquid contact area and achieving rapid cooling.

[0047] 2. Water chamber and water level control The interior of the enclosure stores cooling water, and the water level must be maintained at the designed height to ensure that the exhaust gas is completely submerged in water.

[0048] It is typically equipped with a water level sensor and an automatic water replenishment valve, which automatically replenishes water when the water level is too low and triggers engine shutdown protection when water is scarce.

[0049] 3. Baffles / maze-like passageways The gas phase space installed above the water cavity is composed of multiple steel plates arranged in an alternating pattern.

[0050] Its function is to force the water-washed exhaust gas to change direction multiple times before being discharged, further cooling and separating water droplets, while extending the residence time of the exhaust gas in the chamber to ensure thorough purification.

[0051] 4. Water seal structure This is the core safety design of the exhaust gas treatment box 9. It uses a water column of a certain height to form a "water seal". When the pressure inside the box rises abnormally or backfire occurs, the water seal can block the spread of flames and prevent the explosion from spreading.

[0052] The water seal height is usually designed according to explosion-proof standards and is generally not less than 100mm.

[0053] 5. Exhaust outlet Located at the other end or top of the enclosure, the treated, low-temperature, clean exhaust gas is discharged from here. A small exhaust flame arrester is usually also installed at the outlet as a last line of defense.

[0054] 6. Sewage and drainage outlets Located at the bottom of the tank, it is used to periodically discharge accumulated sludge, carbon residue, and wastewater to keep the interior clean.

[0055] Explosion-proof diesel engine body 5 safety protection system I. Core Role As the core safety device of the explosion-proof diesel engine body 5, it monitors various dangerous working conditions in real time, and automatically alarms, slows down, and stops when abnormalities occur, preventing the ignition of gas and coal dust, ensuring the safety of underground operations, and is a mandatory item for safety certification (MA).

[0056] II. Key Protection Projects (9 Core Items) Gas concentration exceeding the limit: monitor at the air inlet / cab, alarm and shutdown when ≥0.5% (most critical); Exhaust temperature protection: If the temperature at outlet 9 of the exhaust gas treatment box reaches ≥77℃, an alarm will be triggered and the machine will shut down. Surface temperature protection: alarm and shutdown when the outer wall of the machine body, exhaust pipe, etc. reaches ≥150℃; Cooling water temperature protection: Cylinder head / water passage, alarm and shutdown when ≥95℃; Exhaust gas treatment box 9 Water level protection: If the water level is lower than the safety line, the machine will stop immediately; Oil pressure protection: Main oil passage, low pressure alarm and shutdown; Intake negative pressure protection: If the negative pressure after the intake flame arrester is too high, an alarm will be triggered and the machine will shut down (to prevent blockage). Exhaust pressure protection: If the back pressure is too high before the exhaust pipe / exhaust gas treatment box 9, an alarm will be triggered and the machine will shut down; Interlock activation: If the handbrake is not released or the door is not closed, the vehicle cannot be started; manual reset is required after the protection action to restart.

[0057] III. System Composition Sensors (gas, temperature, water level, etc.) → Control host (PLC / explosion-proof controller) → Actuators (audible and visual alarms, flameout devices, etc.) → Display panel (real-time display of parameters and fault codes).

[0058] IV. Working Logic Any parameter exceeding the limit → alarm first → delayed shutdown → manual reset and restart, the whole process is automatic and requires no human intervention.

[0059] The walking module 4 includes a tracked chassis 10, which is mounted on both sides of the housing 24. The control module 3 includes a wireless receiving unit, which is located at the front end of the housing 24. The operator controls the walking module 4 through a wireless remote control. The tracked chassis 10 drives the tracks through a hydraulic drive motor and a reduction mechanism to move the transport vehicle forward, backward, or turn. The wireless receiving unit is used to receive remote control commands and drive the carrier platform 1, the power module 2, and the walking module 4 to complete the corresponding actions. The wireless receiving unit receives the remote control commands transmitted via wireless remote control.

[0060] The working principle or structural principle is as follows: a wireless remote control transmits a command, which is received by a wireless receiving unit. The explosion-proof diesel engine 5 starts and burns diesel fuel in the diesel tank 8 to generate power. This power is then transmitted to the plunger pump 6 via a coupling, distributing the hydraulic system to each carrying platform 1 and the walking module 4 to complete the corresponding actions. After the explosion-proof diesel engine 5 starts, the radiator 7 provides heat dissipation for the explosion-proof diesel engine 5. The exhaust gas treatment box 9 cools, purifies, and eliminates sparks and blocks flame propagation of the exhaust gas, ensuring that the explosion-proof diesel engine 5 will not ignite the surrounding explosive gases during operation. The operator controls the walking module 4 via a wireless remote control. The tracked chassis 10 drives the tracks through a hydraulic drive motor, enabling the transport vehicle to move forward, backward, or turn. When the bracket is loaded, the piston rods of the four hydraulic limiters 16 are reset and disengaged from the top of the carrier plate 15 via a wireless remote control. Then, the piston rods of the two hydraulic cylinders 22 are reset, causing them to move one end of the second connecting rod 21. This, in turn, causes the other end of the second connecting rod 21 to move one end of the first connecting rod 19 via the rotating shaft 18. At this time, one end of the first connecting rod 19 causes the connecting arm 20 to descend. During this process, the carrier plate 15 causes the fixed shafts 13 on the two connecting seats 14 to slide inside the long through groove 12. The other end of the carrier plate 15 moves and tilts, so that the other end of the carrier plate 15 is adapted to the storage position of the bracket, so as to facilitate the loading of the bracket. After loading, the piston rods of the two hydraulic cylinders 22 extend, so that the piston rods of the two hydraulic cylinders 22 drive the other end of the carrier plate 15 to move and reset through the second connecting rod 21, the fixed seat 17, the rotating shaft 18, the first connecting rod 19 and the connecting arm 20. Then, the piston rods of the four hydraulic limiters 16 are controlled to extend. The piston rods of the hydraulic limiters 16 can fix and limit the bracket to prevent the bracket from falling off.
