Description

Technical Field

[0001] The utility model relates to the technical field of traction devices, in particular to a cableway traction device. Background Art

[0002] Overhead freight ropeways are widely used in the construction of power transmission and transformation lines to transport various engineering materials and equipment. Ropeway transportation overcomes the dependence of traditional material transportation methods (human, animal, water, and road) on external conditions, offering superior economic and technical performance.

[0003] For example, the invention patent with announcement number CN103818389B and name of a combined ropeway traction machine includes a power machine, a gearbox, a reduction box and double traction wheels connected in sequence. Its improvement is that: the power machine is arranged on a power base, the gearbox, reduction box and double traction wheels are arranged on a bracket, and the power base and the bracket are connected by bolts and connecting plates and are arranged in the same plane.

[0004] When installing the above-mentioned traction equipment, because there are many devices to be installed and there are rotation distance requirements between individual devices, the overall equipment occupies a large area and has high installation requirements. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a cableway traction device, which is used to solve the technical problems of the existing traction equipment, such as large floor space occupation and high installation requirements.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A cableway traction device includes a support base, a reduction gear box fixedly provided on the support base, a reduction assembly provided in the reduction gear box, a traction roller rotatably provided on the reduction gear box, the traction roller is fixedly connected to the output end of the reduction assembly, a drive motor is fixedly provided on the support base, the output end of the drive motor is fixedly connected to the drive end of the reduction assembly, and the drive motor is provided with a control unit for controlling the speed of the drive motor.

[0008] Working principle:

[0009] This device is a cableway traction device, which is mainly used to pull a designated cableway.

[0010] During installation, you only need to install the reduction gearbox on the support base, install the traction roller on the reduction gearbox, and connect it to the output end of the reduction assembly. Install the drive motor on the support base as well, and connect the output end of the drive motor to the drive end of the reduction assembly. Finally, install the support base in the designated position, and electrically connect the control unit on the drive motor to the external frequency converter. The speed of the drive motor is controlled by the frequency converter and the control unit.

[0011] Beneficial effects obtained:

[0012] Reducing the gearbox and using the speed of the drive motor to achieve speed change can make the structure simpler and more compact, and reduce the overall footprint of the equipment; through direct drive of the drive motor, there is no need for energy conversion through the gearbox, thereby reducing energy loss and improving overall efficiency; the speed can be precisely controlled by the drive motor to achieve smooth speed change, which is more sophisticated and flexible than a mechanical gearbox; and the overall maintenance cost of the equipment is reduced.

The design of the load-bearing shaft 19 and the load-bearing gear 20 can further improve the transmission performance and load capacity. The first output shaft 8 is parallel to the second drive shaft 7 and is rotatably mounted in the reduction box 2.
