[0002] Traditional guide wheel connection structures in power maintenance workshops present numerous problems. First, the complex workshop environment allows dust to accumulate on the guide wheels and related components, increasing rotational resistance and making equipment movement increasingly difficult, severely impacting maintenance efficiency. Second, foreign objects such as hair and ropes frequently appear and easily become entangled in the guide wheels and axles, often causing guide wheel jamming, preventing normal equipment operation and interfering with the maintenance process. Third, dust easily penetrates the bearings, exacerbating friction between the bearings and axles, accelerating component wear, significantly shortening equipment lifespan, increasing maintenance costs and equipment replacement frequency, and failing to meet the efficient and stable working requirements of power maintenance workshops.

[0033] like Figures 1 to 8 As shown, an embodiment of this utility model proposes a guide wheel connection structure for an electrical maintenance workshop, which includes a connecting device 2. A connecting shaft 3 is provided at the upper end of the connecting device 2. The connecting shaft 3 is cylindrical in shape and has a threaded upper end for connecting with other equipment. A bracket 4 is provided at the lower end of the connecting device 2. The bracket 4 is an inverted trapezoid, consisting of a top surface with a circular through hole and two opposing inverted trapezoidal side plates of the same size. The lower ends of the side plates each have circular connecting holes for connecting guide wheels 1. The guide wheels 1 are located between the two side plates and connected via a wheel axle 7. The lower end of the connecting shaft 3 is connected to and passes through the through hole on the top surface of the bracket 4.
[0034] Dust baffles 5 are provided on both sides of the bracket 4 where there are no side plates. The front and cross-section of the dust baffles 5 are curved, with an arc similar to the outer arc of the guide wheel 1, but larger in size. The upper end of the dust baffles 5 is a baffle perpendicular to its surface, and the baffle has multiple screw holes for fixing to the upper side of the bracket 4 with screws. Connecting rods are provided on both sides of the lower end of the baffle, and each connecting rod has a screw hole for fixing to the side plate of the bracket 4 with screws. In this way, the dust baffles 5 can be fixed to the bracket 4, and the inner wall of the dust baffles 5 maintains a sufficient distance from the surface of the guide wheel 1, preventing the guide wheel 1 from being scratched.
[0035] On the inner side of each dust baffle 5, multiple filter bristles 6 are evenly arranged. The filter bristles 6 have a certain degree of elasticity and wear resistance. Each filter bristle 6 is evenly and densely distributed along the inner wall of the dust baffle 5 and is completely fixed to the inner wall of the dust baffle 5. Each filter bristle 6 faces the guide wheel 1 and maintains a certain gap with the guide wheel 1. Through the combined use of the dust baffle 5 and the filter bristles 6, dust and debris can be effectively blocked from falling onto the guide wheel 1 from above. It also ensures that foreign objects such as hair and ropes are intercepted by the filter bristles 6 when they approach the guide wheel 1, without obstructing the guide wheel 1 due to excessive contact. When dust is stirred up or debris falls in the workshop, the dust baffle 5 can change its trajectory, preventing it from falling directly onto the surface of the guide wheel 1. This reduces dust accumulation on the guide wheel 1 and prevents problems such as uneven rotation of the guide wheel 1 and difficulty in moving equipment caused by excessive dust. When thin, long foreign objects such as hair or ropes approach the guide wheel 1 during equipment movement, they will be entangled by the bristles of the filter brush 6, preventing them from further entangled on the guide wheel 1 and axle 7, thus ensuring the normal operation of the guide wheel 1 and reducing equipment failures caused by foreign objects entangled.
[0036] The guide wheel 1 has a circular connecting hole at its center, into which a bearing is installed. Dust covers 8 are installed on both sides of the bearing. The dust cover 8 is a circular cap with an inner diameter slightly larger than the outer diameter of the bearing, and has a circular through hole at its center for the smooth passage of the axle 7. The dust cover 8 effectively prevents dust and impurities from entering the bearing, avoiding increased friction between the bearing and axle 7 due to dust accumulation, reducing wear on both, extending their service life, ensuring the guide wheel 1 can rotate stably for a long time, and guaranteeing the normal movement and guiding operation of the equipment in the power maintenance workshop.
[0037] The installation of guide wheel 1 is relatively simple. First, the bearing needs to be fixed in the center hole of guide wheel 1. Then, dust covers 8 are installed on both sides. Next, guide wheel 1 is placed between the two side plates of bracket 4. Align the center hole of guide wheel 1 with the connecting hole of the side plate. Finally, the wheel axle 7 is passed through the connecting hole of the two side plates of bracket 4. The two ends of wheel axle 7 are threaded. Use nuts to fix both sides to complete the installation of guide wheel 1.
[0038] Working principle: In the power maintenance workshop, the connecting device 2 is a key component. Its upper connecting shaft 3 is connected to other equipment via threads to transmit power and motion. The lower bracket 4 provides support and a mounting base for the guide wheel 1. The wheel axle 7 passes through the connecting hole on the side plate of the bracket 4 and the center hole of the guide wheel 1 and is fixed by a nut to ensure that the guide wheel 1 can rotate flexibly.
[0039] The dust baffle 5, with its arc-shaped structure and fixing method, blocks dust and debris from falling onto the guide wheel 1, preventing dust accumulation from affecting the rotation of the guide wheel 1 and the movement of the equipment. The filter bristles 6, with their elasticity and appropriate gaps, intercept foreign objects such as hair and ropes, preventing them from getting tangled in the guide wheel 1 and the axle 7, thus ensuring the normal operation of the guide wheel 1.
[0040] The guide wheel 1's central bearing ensures smooth rotation, while the dust cover 8 prevents dust from entering the bearing, avoiding increased friction and wear between the bearing and the wheel axle 7 due to dust, extending the equipment's service life, ensuring the stable operation of the entire connection structure, and facilitating efficient power maintenance work.
