Description

Technical Field

[0001] This utility model relates to the field of hydraulic technology, specifically to a hydraulic rotary device for a tape reel vehicle. Background Technology

[0002] In the coal industry, belt conveyors are important equipment in the transportation system and are one of the key pieces of equipment to ensure continuous transportation in coal preparation production. With the increasing use of belt conveyors, the conveyor belt surface needs to be replaced due to wear or other reasons to ensure the normal operation of production activities. Hydraulic belt winding machines are used to efficiently complete the task of replacing belt conveyor belts.

[0003] When the winding machine needs to be moved during operation, the upper and lower parts need to rotate 360 ​​degrees. However, since the hydraulic oil flows through hydraulic hoses, the rotation may cause the hydraulic hoses to become tangled, making the winding machine unable to work properly. Therefore, a hydraulic central rotary joint is needed to allow the upper and lower parts of the system's hydraulic pipeline to rotate 360 ​​degrees relative to each other without interference.

[0004] In hydraulic central rotary joints, when there are many oil lines, the length of the joint needs to be increased to add more oil outlets. This results in different fluid flow velocities in different lines, with the longest line having a very low flow velocity, leading to slow oil output. Furthermore, the sudden turn in the oil output during rotation causes turbulence, and the pressure generated by this turbulence can cause damage to the internal components of the device. To address these issues, this invention provides a hydraulic rotary device for a tape reel vehicle. Utility Model Content

[0007] Preferably, the inner sleeve has a sleeve outlet at its end, and a grid plate is fixedly connected inside the sleeve outlet. The sleeve outlet corresponds to the pipeline outlet, and the grid plate is used to disrupt the turbulence of the fluid inside the inner sleeve.
