Description

Technical Field

[0001] The invention relates to the technical field of cable installation, and in particular to an automatic tensioning mechanism for cable installation. Background Art

[0002] The automatic tensioning mechanism can ensure that the cable maintains constant tension during installation, which is very important for laying and fixing the cable. Constant tension helps prevent the cable from being too loose or too tight during laying, thereby protecting the cable from damage. In complex terrain, the automatic tensioning mechanism can automatically adjust the tension according to terrain changes to ensure that the cable can be laid smoothly in different slopes and curvatures. The automatic tensioning mechanism applies tension by contacting the cable with specific components.

[0003] Dirt, impurities, etc. accumulate at the contact point between the automatic tensioning mechanism and the cable, which will change the friction between the contact parts and the cable. The originally appropriate tensioning force may be too large or too small due to the abnormal change in friction, affecting the quality of cable installation and the safety of subsequent use. After contacting acidic or alkaline dirt, the metal surface will undergo a chemical reaction and gradually corrode, reducing its mechanical properties, making the automatic tensioning mechanism need to be repaired or replaced more frequently.

When the rotating shaft 2021 has the telescopic function, chamfers are provided at the contact positions between the first bevel gear 203 or the second connecting wheel 301 and the block 2022, so that the block 2022 can be smoothly connected to the first bevel gear 203 or the second connecting wheel 301 during the movement, and the multiple utilization of the power structure can be achieved by setting the structural setting of the connecting component 202, thereby improving the utilization efficiency of the structure.

[0039] Working principle: When the mechanism is used for work, the motor 201 in the tensioning unit 200 structure is used for power transmission and operation, and the motor 201 is used as an adjustment structure for power transmission through the connecting component 202. When the connecting component 202 structure transmits power to the adjusting unit 300 structure, the cable is conveniently connected to the internal structure of the bottom plate 102 through the adjusting unit 300 structure, thereby speeding up the working efficiency of the mechanism. When the connecting component 202 transmits the power of the motor 201 to the first bevel gear 203, the first bevel gear 203 drives the first connecting shaft 204 to rotate through the second bevel gear 205, and the first connecting shaft 204 drives the multiple worms 208 to rotate through the second belt 2010 connected to the first connecting wheel 206, and then the worm 208 transmits power The power is transmitted to the tensioning component 207 structure, and the tensioning component 207 structure squeezes and tensions the cable to be installed through the transmission of power. The constant tension helps to prevent the cable from being excessively loose or too tight during the laying process, thereby protecting the cable from damage. At the same time, the worm 208 transmits the power to the structural components of the cleaning unit 209. The cleaning unit 209 structure cleans the structure of the tensioning component 207 during operation, maintains the tensioning setting of the tensioning component 207 structure on the cable surface, and prevents impurities on the cable surface from adhering to the tensioning component 207 structure for a long time and affecting the operation of the tensioning component 207 structure. At the same time, the cleaning unit 209 structure can be quickly replaced, thereby maintaining the high efficiency of the cleaning unit 209 structure.
