Description

Technical Field

[0001] The utility model belongs to the field of mechanical structures, relates to the field of tension wheels, and specifically relates to a waterproof tension guide wheel of a boiler slag scooping machine. Background Art

[0002] Boiler slag scooping machine is a device for scooping slag from boiler. When the slag scooping machine is in operation, it usually uses a chain as a transmission component to transmit power to various components, such as scrapers, drive wheels, etc. Since the chain will be affected by factors such as temperature changes and load changes during operation, the tension of the chain will change, affecting the normal operation of the slag scooping machine. In order to ensure that the chain of the slag scooping machine can operate normally under the influence of various factors, a tensioning guide wheel is often used to adjust the tension of the chain, so that the slag scooping machine can operate smoothly and help reduce damage to the chain.

[0003] The tensioning guide wheel commonly used in the current slag scoop supports the chain through the guide wheel. The direct contact between the guide wheel and the chain will accelerate the mutual wear between the two and shorten their service life. The guide wheel rotates along the bearing, making the chain run smoothly and labor-saving, but the ash water remaining on the chain and the ash water on the slag scoop will enter the bearing. The slag contained in the ash water will enter the bearing, which will affect the operation of the bearing, increase the bearing wear, and shorten the service life of the bearing. Utility Model Content

[0005] The technical solution adopted by the utility model is: to provide a boiler slag scoop machine waterproof tensioning guide wheel, including a guide wheel assembled on a bearing and a mounting shaft, the guide wheel outer wall sealing sleeve is provided with a protective pad, the protective pad corresponds to the shape of the guide wheel, both ends of the protective pad protrude from the two ends of the guide wheel, and both ends of the inner wall of the protective pad are sealed with annular support pads, the support pads are abutted against the outer wall of the guide wheel; the inner ring wall of the support pad is sealed and rotatably installed with annular connecting pads, the inner ring wall of the connecting pad is sealed and rotatably installed with a sleeve, and the sleeve is sleeved with the mounting shaft.

[0006] The protective pad is mounted on the outer wall of the guide wheel so that the guide wheel contacts the chain through the protective pad to reduce wear. The protective pad is easy to maintain and replace and has low cost. The mounting support pads and connecting pads at both ends of the protective pad shield and protect the bearings, thereby improving the protective effect on the bearings, reducing the contact between gray water and the bearings, improving the waterproof effect of the guide wheel, extending the service life of the guide wheel, and improving safety and reliability in use.

[0008] After the baffle is separated from the wheel body, the wheel body and the bearing sleeve rotate, and the baffle does not interfere with the installation of the protective pad, making the protective pad easy to disassemble and assemble and flexible to use. After the baffle is assembled with the wheel body, the baffle abuts against the bearing to shield and protect the bearing, thereby improving the protective effect thereof.

[0009] To further optimize the technical solution, screws are evenly arranged on the outer wall of the baffle along the circumferential direction, and the screws are all threadedly connected to the wheel body.

[0010] The baffle is installed on the wheel body by screws, which is easy to operate and firm and reliable to use.

[0011] To further optimize the technical solution, both ends of the outer side wall of the support pad are threadedly connected with pins along the circumferential direction, the pins are inserted into the support pad and threadedly connected with the outer side wall of the support pad.

[0013] To further optimize the technical solution, the inner ring wall of the support pad is provided with a connecting groove, and the connecting pad and the connecting groove are sealed and rotatably installed.

[0014] The support pad is installed with the connecting pad through the connecting groove. The installation groove partially wraps the connecting pad to make its seams staggered, so as to increase the difficulty of gray water flowing into the bearing through the seams, thereby improving the waterproof and protective effect of the bearing.

[0015] To further optimize the technical solution, the sleeve includes a cylinder body mounted on the mounting shaft and a gasket fixedly mounted on the outer wall of the cylinder body, the outer wall of the gasket is rotatably fitted with the inner ring wall of the connecting gasket, and gaskets are fixedly mounted on both ends of the outer wall of the gasket, and the gaskets are sealingly and rotatably connected to the outer wall of the connecting gasket.
