Description

Technical Field

[0001] This utility model belongs to the field of mining equipment technology, and in particular relates to a large mining truck-mounted sprinkler structure based on a diesel water pump. Background Technology

[0002] Mining trucks are heavy-duty dump trucks used in open-pit mines for rock and soil stripping and ore transportation. During the mining, crushing, storage, transportation, and loading / unloading processes in open-pit mines, large amounts of dust are emitted into the atmosphere in the form of fugitive emissions, forming fine particulate matter and dust, causing dust pollution and affecting the environment and the health of on-site workers. Using water trucks to spray water can effectively reduce dust concentration and maintain a clean working environment. Utilizing idle large mining trucks as water trucks can reduce enterprise costs and achieve efficient equipment utilization.

[0003] Traditional water sprinkler trucks operate by using an engine to drive a gearbox, which in turn uses a power take-off (PTO) to power a water pump via a drive shaft, thus pressurizing the water flow. However, the large mining trucks being modified are enormous, exceeding 9 meters in length and nearly 4 meters in height, weighing up to 40 tons, with a water tank capacity of 50 tons and a total load weight of up to 90 tons. Their complex structure, with the PTO output connected to a gear pump to provide hydraulic power to other components, and the enormous size of these parts, makes structural modifications difficult. Modifying a traditional water sprinkler truck presents significant challenges: high modification difficulty, high cost, and the potential for conflicts between the modified structure and the truck's normal functions, posing safety hazards. Furthermore, the small size of the built-in generator and battery in the mining truck makes it impossible to power the electric water pump, and the water mist generated during spraying can easily enter the motor, causing a short circuit and further posing a safety risk.

[0004] These problems not only increase the difficulty of the modification and affect the reliability of the equipment during operation, but also increase the modification cost and risk. Summary of the Invention

[0005] The purpose of this utility model is to convert idle mining trucks into water sprinkler trucks. It proposes a large mining truck-mounted water sprinkler structure based on a diesel water pump to solve problems such as excessive difficulty in the conversion process, high conversion cost, and safety hazards.

[0006] The objective of this utility model is achieved through the following technical solution: This utility model discloses a large mining truck-mounted sprinkler structure based on a diesel water pump, comprising a water tank for the mining truck. Its features include drainage pipes installed at the rear and front of the water tank, a fire-fighting system installed on the front platform of the mining truck, and a sprinkler system mounted on a bolt-mounted bracket below the water tank. The sprinkler system includes a manual valve I connected to the drain pipe at the tail of the water tank, an electric valve connected to the manual valve I, and two water flow pipes connected to the electric valve via a tee pipe I. One is a pressurized pipe connected to a sprinkler diesel water pump, and the other is a gravity bypass. A manual valve II is installed on the gravity bypass. A spray horizontal pipe is connected to the manual valve II. The spray horizontal pipe is connected to the gravity bypass and the sprinkler diesel water pump via the tee pipe II.

[0007] The fire protection system includes a fire pipeline inlet connected to the drainage pipeline at the front of the water tank, a manual valve III connected to the fire pipeline inlet, a filter II connected to the manual valve III, a fire diesel water pump connected to the filter II, and a fire pipeline outlet connected to the fire diesel water pump.

[0008] The spray pipe is uniformly equipped with a set of fan-shaped nozzles.

[0009] The water pump is equipped with a filter I at its inlet to filter out large particulate impurities in the incoming water.

[0010] The water spraying system is fixed to the welded I-beam base by bolts. A rubber buffer pad is installed between the water spraying diesel pump and the I-beam base. A structural support plate is provided on the I-beam base. A set of bolt connecting plates is welded to the extended edge of the I-beam base. This bolt connecting plate is connected to the bolt bracket welded to the bottom of the truck body through connecting angle steel with bolt holes at both ends, so as to realize the mounting of the water spraying system.

[0011] The fire-fighting diesel pump and the sprinkler diesel pump are controlled by an electric push rod to open and close the throttle. The electric push rod, the electric valve and its control system are powered by a 24V vehicle battery. The starter motors of the fire-fighting diesel pump 16 and the sprinkler diesel pump 1 are powered by a 12V battery.

[0012] Advantages of this utility model: This utility model discloses a large-scale mining truck-mounted sprinkler structure based on a diesel water pump. The entire set of equipment is fixed to a welded I-beam base with bolts. A rubber buffer is installed between the diesel water pump and the I-beam base.

[0019] The specific embodiments of this utility model are further described below with reference to the accompanying drawings.

[0020] like Figure 1-5 As shown, this utility model discloses a large mining truck-mounted sprinkler structure based on a diesel water pump, comprising a water tank 15 of the mining truck. Its features include drainage pipes installed at the rear and front of the water tank 15, a fire-fighting system installed on the front platform of the mining truck, and a sprinkler system installed on the lower part of the water tank 15 via bolt brackets 21. The sprinkler system includes a manual valve I2 connected to the drain pipe at the tail of the water tank 15, an electric valve 3 connected to the manual valve I2, and two water flow pipes connected to the electric valve 3 via a three-way pipe I4. One is a pressurized pipe connected to the sprinkler diesel water pump 1, and the other is a gravity bypass. A manual valve II5 is installed on the gravity bypass. A spraying horizontal pipe 7 is connected to the manual valve II5. The spraying horizontal pipe 7 is connected to the gravity bypass and the sprinkler diesel water pump 1 via a three-way pipe II8.

[0021] The fire protection system includes a fire pipe inlet 17 connected to the front drainage pipe of the water tank 15, a manual valve III 18 connected to the fire pipe inlet 17, a filter II 19 connected to the manual valve III 18, a fire diesel water pump 16 connected to the filter II 19, and a fire pipe outlet 9 connected to the fire diesel water pump 16.

[0022] The spray pipe 7 is uniformly provided with a set of fan-shaped nozzles.

[0023] The water pump 1 is equipped with a filter I6 at its inlet to filter out large particulate impurities in the incoming water.

[0024] The water spraying system is fixed to the welded I-beam base 10 by bolts. A rubber buffer pad 13 is installed between the water spraying diesel pump 1 and the I-beam base 10. A structural support plate 11 is provided on the I-beam base 10. A set of bolt connecting plates 12 are welded to the extended edge of the I-beam base 10. This bolt connecting plate 12 is connected to the bolt bracket 21 welded to the bottom of the truck body through connecting angle steel 20 with bolt holes at both ends, so as to realize the mounting of the water spraying system.

[0025] The fire-fighting diesel water pump 16 and the sprinkler diesel water pump 1 are controlled by an electric push rod to open and close the throttle. The electric push rod, the electric valve 3, and their control system are powered by a 24V vehicle battery, while the starter motors of the fire-fighting diesel water pump 16 and the sprinkler diesel water pump 1 are powered by a 12V battery. The vehicle battery also charges the starter motors of the diesel water pumps, preventing them from running out of power due to repeated starts in a short period.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific examples.

[0027] A water tank (15) was modified from an idle large mining truck cargo box, with drainage pipes added to the rear and front right side of the tank. Long-distance firefighting and road watering operations are achieved through a fire suppression system installed on the front right platform of the mining truck and a sprinkler system mounted on the underside of the truck's water tank via welded detachable brackets. Both the sprinkler and fire suppression systems are powered by diesel water pumps with independent fuel tanks, reducing the modification difficulty compared to traditional power take-offs and eliminating the risk of water ingress and short circuits associated with electric water pumps. The firefighting and sprinkler functions are controlled by an independent control system powered by the vehicle's battery, while the diesel water pump starter motor is powered by its own battery, which charges the battery upon starting.

[0028] The fire diesel water pump 16 and the sprinkler diesel water pump 1 are controlled by an electric push rod to open and close the throttle. The electric push rod, the electric valve 3 of the sprinkler pipeline and its control system are powered by a vehicle-mounted 24V battery. The diesel water pump starter motor is powered by a 12V battery. At the same time, the vehicle-mounted battery is also responsible for charging the diesel water pump starter motor to avoid the diesel water pump starter motor from running out of power due to multiple starts in a short period of time.

[0029] The water sprinkler system, fire protection system, and mining truck operate relatively independently, and the modification process only involves the modification of the truck's main box structure. Other units of the mining truck are not modified, and the failure of a single system does not affect the safe operation of the entire vehicle.

[0030] like Figure 1As shown, the sprinkler system has two spray lines. A line is installed from the outlet of water tank 15, connecting to manual valve I2 and electric valve 3. After electric valve 3, a T-junction I4 divides the line into two water flow channels: one is the pressurized line used for normal spraying, and the other is a gravity bypass. A manual valve II5 is installed at the inlet of the gravity bypass. After manual valve II5, the horizontal spray pipe 7 is connected. The bypass is normally closed; its function is to be manually opened to drain the water tank for maintenance in case of a pressurized line malfunction. The pressurized line is pressurized by an electrically startable mud diesel booster pump (sprinkler diesel pump 1). A basket filter I6 is connected to the inlet of sprinkler diesel pump 1 to filter large particles in the incoming water, ensuring its normal operation. The outlet of sprinkler diesel pump 1 is connected to the horizontal spray pipe 7. The components of the sprinkler system are connected flexibly. The use of flexible connections can absorb vibration, reduce noise, prevent displacement damage to pipes, and adjust for installation errors.

[0031] Sprinkler installation location as follows Figure 3 As shown. The entire water spraying system is installed in the trapezoidal space 14 formed by the water tank 15 at the rear of the vehicle and the rear tires. A bolt bracket 21 with bolt holes is welded to the sloping surface at the bottom of the water tank. The entire water spraying system is fixed on a welded I-beam base 10. A rubber buffer pad 13 is installed between the diesel water pump 1 and the I-beam base 10 to reduce the impact of vibration generated by the diesel water pump 1 during operation on the overall water spraying structure. A U-shaped support plate 11 is welded to the I-beam base 10 to support the water spraying system pipeline structure and prevent the entire water spraying pipeline from bending downwards due to flexible connections.

[0032] A set of bolted connecting plates 12 are welded to the protruding edge of the I-beam base 10. Due to the large weight of the diesel pump and its position being biased to the right, the bolted connecting plates 12 on the right side and the I-beam base 10 are installed closely to ensure that the overall structure is evenly stressed. The bolted connecting plates 12 are connected to the bolt brackets 21 welded to the inclined surface at the bottom of the truck bed through connecting angle steel 23 with bolt holes at both ends, so that the water sprinkler can be mounted on the mining truck. The bolted connection facilitates disassembly and installation, providing convenience for the maintenance of the mining truck.

[0033] Fire protection system structure such as Figure 5 As shown, the drain outlet at the front of the water tank 15 is connected to the inlet 17 of the fire pipeline, followed by a manual valve Ⅲ 18 and a filter Ⅱ 19. It is then connected to the inlet of the fire diesel water pump 16 via a flexible connection. The outlet of the fire diesel water pump 16 is connected to the outlet 9 of the fire pipeline via a flexible connection. The outlet 9 of the fire pipeline can be connected to a fire monitor to achieve long-distance fire extinguishing. For locations in the mining site that mining trucks cannot enter or blind spots that the fire monitor cannot reach, a fire hose can be connected to a fire nozzle outside the outlet for fire extinguishing.
