The equipment structure of electric transfer cart mainly consists of main body, 2 driving wheels, 2 driven wheels, rubber buffer block, copper bar conductive strip, motor, reducer, electromagnetic brake, body insulation pad, copper block power-taking leg, electrical control system, etc. It is a green transportation tool with battery as power source, spacious cargo space and convenient transportation.
I. Definition and characteristics
1. Definition
Electric transfer cart is a motor vehicle driven by electricity, with a flat-bed carriage, used to transport goods. It is widely used in metallurgy, coal, mining, electromechanical, heavy industry, light industry, automobile, shipbuilding, railway, dock and other industries. It adopts a three-phase low-voltage rail power supply method. The power supply system is a step-down and step-up process. The 380V voltage is reduced to a safe voltage of 36V and transmitted to the walking track with special insulation treatment. The on-board sliding power-taking copper block and the walking track frictionally take electricity. After taking electricity, it is transmitted to the on-board electrical control cabinet and stepped up to 380V to provide power for the electric transfer cart.
2. Features
(1) Environmental protection and energy saving: The electric transfer cart uses batteries as a power source, with zero emissions, which is in line with the concept of green travel.
(2) Low noise: The electric transfer cart has low noise during operation, reducing urban traffic noise pollution.
(3) Easy to operate: The electric transfer cart uses an electronic power steering and braking system, and the driving operation is simple and easy to learn.
(4) Spacious cargo space: The electric transfer cart compartment is a flat-bed design with high space utilization, suitable for the transportation of goods of various sizes.
(5) Strong adaptability: The electric transfer cart can flexibly shuttle in different scenes such as urban roads, communities, shopping malls, etc. to meet diverse transportation needs.
II. Application fields
1. Logistics industry: Electric transfer carts are widely used in the logistics field, such as express companies, warehousing and distribution, etc.
2. Sanitation industry: Electric transfer carts can be used for sanitation work such as garbage removal and road cleaning.
3. Postal industry: Electric transfer carts can be used for the delivery of express parcels in the postal field.
4. Factory workshop: Electric transfer cart can be used for material handling and transportation in the workshop.
5. Commercial places: Electric transfer cart can be used for commodity distribution, cargo handling, etc. in commercial places.
III. Working principle
380V AC is led to the transformer and reduced to 36V two-phase AC, which is connected to two rails respectively. The transfer cart takes power through the wheels on the track, and introduces 36V AC into the on-board electrical box. The rectifier module rectifies the 36V AC to 36V DC, and then controls the DC motor through the DC control system to start, stop, move forward, move backward, adjust the speed, etc. of the transfer cart.
IV. Development trend
1. Technological innovation: With the advancement of battery technology, the cruising range and charging speed of electric transfer cart will be improved to meet the needs of higher frequency transportation.
2. Intelligent development: Electric transfer cart will introduce technologies such as intelligent driving and vehicle networking to improve the safety and operating efficiency of vehicles.
3. Product differentiation: For different application scenarios, electric transfer cart will develop diversified products to meet personalized needs.
4. Industry chain integration: The electric transfer cart industry chain will be further integrated to achieve coordinated development of upstream and downstream enterprises, reduce costs and improve overall competitiveness.
5. Policy support: Driven by the national new energy vehicle policy, the electric transfer cart market will continue to maintain rapid growth.
In short, as a green and environmentally friendly transport tool, electric transfer carts are widely used in metallurgy, coal, mining, electromechanical, heavy industry, light industry, automobile, shipbuilding, railways, docks and other industries.
