Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of composite bus accompanying cables, in particular to a composite bus accompanying cable for a tower elevator. Background Art
[0002] In recent years, with the advancement of "carbon neutrality", my country has advocated the vigorous development of clean energy. There are abundant wind resources in China's coastal areas and northwest open areas. Wind power generation has also been widely developed and applied. The height of the wind turbine tower is generally around 100 meters or even higher. The installation and daily maintenance of the wind turbines require personnel to go up and down by using the internal tower elevator.
[0003] The Siemens profibus communication bus cables in industrial cables are all fixedly installed and used, while the elevator system is a mobile mechanical device that cannot be fixedly installed and used. The communication bus must be compounded into the elevator accompanying cable. At present, the accompanying cable generally uses coaxial cables, shielded wire pairs, network cables and optical fiber cables to transmit media, video, broadcast, control command and other signals, and the industrial bus is compounded into the accompanying cable. The wind turbine elevator system is a flexible mobile mechanical device. The elevator accompanying cable is basically fixed at one end to the shaft wall and the other end to the car, and the middle is free to hang and move. Due to the strong wind at the seaside or the top of the mountain where the wind turbine is installed, the tower will be swung by the wind, and the cable will also swing and rub the inner wall of the tower to damage the cable. This swing problem is generally solved by adding a tension wheel. After the cable passes through the tension wheel, higher requirements are put forward for the cold resistance, oil resistance, tensile resistance, wear resistance and mobile life of the cable. In order to achieve the purpose of improving the service life and safety of the cable, a composite bus accompanying cable for tower elevator is provided. Utility Model Content

[0023] In this embodiment: the arc block 5 is made of elastic material. When the protective sleeve 103 is squeezed, the arc block 5 undergoes elastic deformation to protect the internal core 102 and conductor 101 and reduce the squeezing thereof; at the same time, the arc block 5 contacts the core 102 to limit the core 102 to prevent it from moving in the protective sleeve 103 during use, thereby preventing it from being squeezed with the protective sleeve 103 and causing wear.

The overall cable is extruded with an environmentally friendly cold-resistant, oil-resistant, and wear-resistant elastomer protective sheath 4. The bundled conductor 101 is composed of multiple strands of soft copper wire. A layer of cold-resistant low-viscosity insulating material is extruded outside the conductor 101 to form a core 102.
