Description

Technical Field

[0001] The utility model relates to the technical field of cantilever warehouse unloading machines, in particular to an explosion-proof power-taking slip ring. Background Art

[0002] The cantilever discharge machine is mainly used for cylindrical silos, including a center slewing bearing and a cantilever. The cantilever is driven by a driving device to rotate around the center slewing bearing, thereby concentrating the stored materials on the center slewing bearing for centralized discharge. A discharge auger is installed in the cantilever.

[0003] The discharge auger of some cantilever discharge machines is driven by a motor, and the motor rotates with the cantilever, and then needs to be powered by an explosion-proof power slip ring. The explosion-proof power slip ring includes a fixed shaft for fixing to the central slewing bearing and a rotating cylinder for fixing to the cantilever. The upper end of the fixed shaft extends into the rotating cylinder and is fixed with a slip ring. The rotating cylinder is fixed with a power brush that matches the slip ring. The rotating cylinder and the fixed shaft are both made of stainless steel and have a good explosion-proof effect.

[0004] During use, an extended support device is required because the fixed shaft is far away from the fixed part of the center slewing bearing. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide an explosion-proof power-taking slip ring which connects a fixed shaft and a central slewing bearing by extending a supporting device.

[0007] Furthermore, the extension frame is tubular, and the connecting ring is fixed coaxially with the extension frame.

[0008] Furthermore, the adjustment seat includes a base that cooperates with the connecting ring, and the base is provided with a connecting tube that cooperates with the fixed shaft. The connecting tube is sleeved outside the fixed shaft, and an adjustment rod is provided between the connecting tube and the fixed shaft. The relative position between the connecting tube and the fixed shaft can be adjusted through the adjustment rod.

[0009] Furthermore, there are 3-4 adjusting rods, which are evenly fixed on the same circumference of the fixed shaft. The ends of the adjusting rods are provided with threads, and the connecting tube is provided with openings that match the adjusting rods.

[0010] Furthermore, the adjusting rod is sleeved with a contoured pressing block that matches the connecting tube.

[0011] The beneficial effects of the present invention are: the fixed shaft is connected to the extended support device, the extended support device is fixed to the fixed platform, so that the fixed shaft is fixed, and the rotating cylinder is fixed to the rotating body, thereby meeting the application of the explosion-proof power slip ring when the distance between the rotating body and the fixed platform is large.

[0017] Example 1

[0018] like Figure 1-2 As shown, an explosion-proof power-taking slip ring is used for a cantilever warehouse unloading machine, including a fixed shaft 7 and a rotating cylinder 1. The upper end of the fixed shaft extends into the rotating cylinder and is fixed with a collector ring (not shown in the figure). The rotating cylinder is fixed with a power-taking brush (not shown in the figure) that matches the collector ring. The rotating cylinder and the fixed shaft are both made of stainless steel and have good explosion-proof effect.

[0019] The fixed shaft is connected to an extension support device, and the extension support device includes a connecting seat 9 for connecting to a fixed platform. In this embodiment, the fixed platform refers to the fixed base of the central rotary support of the cantilever warehouse discharger. A support frame is installed on the fixed base, and the connecting seat is fixed on the support frame. The connecting seat is disc-shaped, and the connecting seat is connected to an extension frame 8. The extension frame is tubular, specifically a seamless steel pipe. The cables are installed in the extension frame to protect the cables. The extension frame is coaxial with the central rotary support. A connecting ring 10 that matches the fixed shaft is installed at the end of the extension frame. The connecting ring is coaxially welded and fixed to the extension frame. The fixed shaft is connected to an adjustment seat that matches the connecting ring, which is convenient for adjustment and maintenance. The adjustment seat includes a base 11 that matches the connecting ring. The base is bolted to the connecting ring. A connecting tube 12 that matches the fixed shaft is welded and fixed on the base. The connecting tube is sleeved on Outside the fixed shaft, an adjusting rod 14 is installed between the connecting tube and the fixed shaft, and the relative position between the connecting tube and the fixed shaft can be adjusted by the adjusting rod. Specifically, there are 3-4 adjusting rods, which are evenly fixed on the same circumference of the fixed shaft. The end of the adjusting rod is processed with a thread, and the connecting tube is processed with an opening that matches the adjusting rod. The opening extends to the upper end of the connecting tube, so that the connecting tube and the fixed shaft can move relative to each other for easy adjustment.
