Description

Technical Field

[0001] The invention relates to the fields of engineering machinery and new energy, and is a range-extending traction machine device with hybrid power input. Background Art

[0002] With the development of my country's national economy, the demand for electricity in various industries represented by manufacturing is also increasing, but the construction of power grids cannot meet the growing demand for electricity. In order to break the long-term lag in my country's power grid construction, a new round of power grid expansion projects and ultra-high voltage transmission line construction with the goal of cross-regional power transmission have emerged in various places. Tension stringing is the main form of power grid transmission line construction, and cable traction machine is the key equipment for tension stringing construction. As the key equipment for tension stringing construction, cable traction machine has huge market demand, but these equipment currently have obvious defects: 1. The cable traction machine engine drives the gear device through the linkage shaft, and the gear device drives the pulley to rotate and traction cable.

[0003] 2. When the cable traction machine is working, the engine output is constant and the energy utilization rate is low.

[0004] 3. The output power of traditional diesel engines in traction machines is fixed, and energy loss is serious under low load conditions.

[0005] In view of the above problems, the present invention designs a hybrid power input extended-range traction device to solve the problem of low energy utilization rate of the device and improve energy utilization efficiency. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a range-extended traction machine with high energy utilization, stable power transmission, simple structure, easy assembly and manufacturing process, and convenient installation. The present invention relates to a range-extended traction machine, comprising 1. a battery pack, 2. an inverter, 3. an electric motor, 4. a power coupling device, 5. a traction machine, 6. a transmission shaft, 7. an engine, and 8. electric wires. The present invention solves the above technical problem with the following technical solution.

[0007] The technical solution of the present invention is achieved by the following measures: A hybrid input extended-range traction device, whose power transmission includes 7 engines, 5-3 gear sets, 1 battery set, 2 inverters, 3 motors, 4 power coupling devices, 6 transmission shafts, and 5-1 tensioning wheel. There are two routes for the output end power to the 5-3 gear set, one is connected to the 3 motors; the other is connected to the 7 engine. The first input route power is transmitted from the 7 engine to the 4 power coupling devices, and the 4 power coupling devices input power to the 5-1 tensioning wheel through the 5-3 gear set and the 6 transmission shaft. The other route 1 battery set is connected to the 2 inverters to convert direct current into alternating current to drive the 3 motors to rotate. The output end of the 3 motors is connected to the 4 power coupling devices, and the 4 power coupling devices drive the 5-3 gear set and the 6 transmission shaft to input power to the 5-1 tensioning wheel.

[0008] The advantages of the present invention are: 1. When the load power is low, only the engine is used as the power source, which can reduce the engine power.

[0009] 2. When the load power is large, the engine and electric motor are used as the power source, and the power setting is flexible.

[0010] 3. The engine and the electric motor serve as power sources at the same time, increasing the energy utilization efficiency of the system. BRIEF DESCRIPTION OF THE DRAWINGS
