Description

Technical Field

[0001] This utility model relates to the technical field of suction and exhaust vehicle equipment, and in particular to a dual-drive (oil and electricity) vacuum pump system for suction and exhaust vehicles. Background Technology

[0002] Suction trucks are special vehicles widely used in industries such as steel and thermal power generation. They collect and transport dry materials such as dust or liquid materials such as sewage from containers or scattered areas, and then discharge the collected materials at the destination to achieve long-distance material handling and reuse, simplifying material handling work.

[0003] In practical work, the suction and exhaust vehicles used in the existing technology are equipped with a special negative pressure vacuum pump system, which usually adopts a chassis engine power take-off and is driven by belt pulley transmission. Due to the large power, the fuel consumption is large and the carbon emissions are high during operation, which brings many inconveniences.

[0004] Therefore, this utility model provides a dual-drive (oil and electricity) vacuum pump system for suction and exhaust vehicles. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a dual-drive vacuum pump system for suction and exhaust vehicles that adds an external mains power drive function without affecting the original drive system. Depending on the on-site operating environment conditions, the system can switch to mains power to drive the vacuum pump, thereby reducing carbon emissions, saving fuel, and achieving considerable energy-saving effects.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a dual-drive (oil and electricity) vacuum pump system for suction and exhaust vehicles, including an on-board vacuum pump. A chassis power take-off is installed on one side of the vehicle-mounted vacuum pump. An electric motor is installed on the side of the chassis power take-off away from the vehicle-mounted vacuum pump. A motor drive belt is fixedly connected to the output end of the electric motor. A vacuum pump drive belt is fixedly connected to the output end of the vehicle-mounted vacuum pump. The vacuum pump drive belt is located on the side of the motor drive belt away from the electric motor. An intermediate pulley assembly is installed between the vacuum pump drive belt and the motor drive belt. One end of the intermediate pulley assembly is connected to the vacuum pump drive belt, and the other end of the intermediate pulley assembly is connected to the motor drive belt. The intermediate pulley assembly is used to connect the vacuum pump drive belt and the motor drive belt. One end of the chassis power take-off is fixedly connected to a drive shaft, and the end of the drive shaft away from the chassis power take-off is fixedly connected to the motor drive belt. The drive shaft is used to connect the chassis power take-off and the motor drive belt.

[0007] In a preferred embodiment, the vehicle-mounted vacuum pump has equidistantly distributed heat dissipation holes on its outer side. These holes help the vehicle-mounted vacuum pump to dissipate heat during operation, extending the service life of the equipment. The motor drive belt has two first rotating rollers internally connected to it. One side of one of the first rotating rollers is fixedly connected to one end of the drive shaft, and the other side of the first rotating roller is fixedly connected to the output end of the motor. Multiple devices can be connected normally through the two first rotating rollers.

[0008] In a preferred embodiment, the vacuum pump drive belt has two second rotating rollers internally connected to it. One side of one of the second rotating rollers is fixedly connected to one end of the intermediate pulley assembly, and one side of the other second rotating roller is fixedly connected to the output end of the vehicle-mounted vacuum pump. Multiple devices are normally connected through the two second rotating rollers. A power take-off switch is installed on the side of the chassis power take-off away from the drive shaft. A second power cable is fixedly connected between the power take-off switch and the chassis power take-off, and the power take-off switch and the chassis power take-off are normally connected through the second power cable.

[0009] In a preferred embodiment, a mains power motor starter cabinet is installed on the side of the motor away from the motor drive belt. The mains power motor starter cabinet is provided with a first power cable on the side away from the motor. The other end of the first power cable extends into the motor. The first power cable is used to connect to the mains power nearby.

[0010] In a preferred embodiment, the mains-powered motor starter cabinet has a main control board inside, and a control chip is fixedly connected to the outside of the main control board. The vehicle vacuum pump, chassis PTO, mains-powered motor starter cabinet, motor, first power cable, and PTO switch are all electrically connected to the control chip. The control chip is used to control the operation of the vehicle vacuum pump, chassis PTO, mains-powered motor starter cabinet, motor, first power cable, and PTO switch, realizing unified management of electrical equipment. During use, the fuel-driven operation process is as follows: initially, the first power cable is disconnected, and the mains-powered motor starter cabinet... With the engine off, start the engine and turn on the power take-off switch located in the cab. The chassis power take-off will start working, driving the intermediate pulley assembly through the drive shaft, and then driving the vehicle vacuum pump through the vacuum pump drive belt to start normal operation. At this time, the motor is in an unloaded follow-up state. Mains power drive process: Turn off the power take-off switch, the power take-off has no output and is in an unloaded follow-up state. Connect to the nearest mains power using the first connection cable, turn on the mains motor starter cabinet, start the motor, drive the intermediate pulley assembly through the motor drive belt, and then drive the vehicle vacuum pump through the vacuum pump drive belt to start normal operation.

The chassis PTO begins to work, driving the intermediate pulley assembly through the drive shaft, and then driving the vehicle-mounted vacuum pump through the vacuum pump drive belt to start normal operation. At this time, the motor is in an unloaded follow-up state. With the PTO switch off, the PTO is in an unloaded follow-up state with no output. Connect the first power cable to the nearest mains power source, turn on the mains motor starter cabinet, start the motor, and drive the intermediate pulley assembly through the motor drive belt, which in turn drives the vacuum pump through the vacuum pump drive belt. The vehicle-mounted vacuum pump starts working normally. The outer side of the vehicle-mounted vacuum pump has equally spaced heat dissipation holes, which help the vehicle-mounted vacuum pump to dissipate heat during operation, thus extending the service life of the equipment. The drive shaft is used to connect the chassis power take-off and the motor drive belt. The intermediate pulley assembly is used to connect the vacuum pump drive belt and the motor drive belt, ensuring normal operation of the equipment. Multiple devices are normally connected through two first and second rotating rollers. The power take-off switch and chassis power take-off are normally connected through the second power cable. This design does not affect the original drive function. By adding a drive function that can be connected to external mains power, energy saving and emission reduction functions are achieved. The overall structure is simple, the switching is fast, and the reliability is high. Attached Figure Description
