Description

Technical Field

[0001] This utility model relates to the field of idler roller adjustment devices, and in particular to a tension adjustment and anti-drop device for inclined shaft idler rollers. Background Technology

[0002] Inclined shaft idlers are key components in inclined shaft or steep-angle transportation. Their function is to support the wire rope, reduce running resistance, reduce the sliding friction between the wire rope and the ground, and extend the service life of the wire rope. Inclined shaft idlers generally consist of an inclined shaft idler fixing device and an inclined shaft idler roller assembly. The inclined shaft idler fixing device is used to ensure the stable fixation of the idler, while the inclined shaft idler roller assembly is used to contact the wire rope and support and guide it.

[0003] Currently, because the fixing devices for inclined shaft idlers are mostly installed on inclined parts, the wire ropes are prone to loosening under the influence of factors such as slope, vibration and working time. After loosening, the wire ropes in operation are prone to deviate from the roller assembly of the inclined shaft idler, which can lead to rope jamming and have a significant impact on the normal use of the inclined shaft idlers.

[0031] The installation and use process of the tension adjustment and anti-fall device for inclined shaft idler rollers according to this utility model is as follows:

[0032] I. The installation process is as follows:

[0033] First, the installer can install the mounting frame 1 on the external working part, and then install the tension adjustment part 2 on the mounting frame 1. Specifically, the bottom of the worm gear jack 22 can be installed on the mounting frame 1, and the drive motor 21 can be installed on the power input end of the worm gear jack 22 to drive the worm gear jack 22 to work. The lifting worm 23 can be installed on the worm gear jack 22, and the support bracket 24 can be installed at the bottom position of the roller mechanism 4.

The two roller assembly 43 is installed. During installation, the lower part of the fixed support 421 is bolted to the roller frame 41. A roller shaft 423 adapted for the roller body 422 is installed on the fixed support 421. The two sides of the roller shaft 423 are assembled to the fixed support 421 through bearings. The roller body 422 is fixedly installed on the roller shaft 423. An anti-deviation mechanism 5 is installed on the side of the roller frame 41.

[0034] II. In practical use, contact grooves 6 for contacting the wire rope are machined on the anti-deviation wheel body 53 and the roller body 422. At this time, with respect to the roller, the wire rope is located within the contact groove 6 on the roller body 422 (the wire rope is spatially perpendicular to the roller shaft 423). With respect to the anti-deviation wheel body 53, the wire rope is located within the contact groove 6 on the anti-deviation wheel body 53 (the wire rope is spatially perpendicular to the anti-deviation wheel shaft 54). The anti-deviation wheel body 53 is located on the side of the wire rope in the direction of travel, contacting the wire rope through its contact groove 6. When the wire rope is running, the bottom of the wire rope contacts the roller body 422, causing the roller body 422 to rotate, and the side of the wire rope contacts the anti-deviation wheel body 53. The anti-deviation wheel 53 rotates upon contact, stabilizing and limiting the wire rope to prevent deviation. It remains within the contact groove 6 on the roller 422. When tension adjustment is needed, the drive motor 21 in the tension adjustment unit 2 operates. The drive motor 21 drives the worm gear lifter 22 to raise the lifting worm 23. The lifting worm 23 then pushes the idler roller mechanism 4 to rise. At this time, the roller 422 on the idler roller mechanism 4 can adjust the wire rope tension (increasing the wire rope tension), preventing the wire rope from sagging or loosening, and ensuring stable operation.
