Description

Technical Field

[0001] The utility model relates to the technical field of overhead crane equipment, and particularly relates to an overhead crane trolley wire guide cleaning device and an overhead crane. Background Art

[0002] In the field of automobile manufacturing, the pretreatment and electrocoating processes of painting endow the vehicle body with an electrocoating layer, making it have excellent rust and corrosion resistance properties. According to the on-site flow production, the transfer of workpieces between different processes and tanks needs to be realized by various mechanized transportation equipment. An overhead crane (automatic hoist conveyor) is a mechatronic conveying equipment. Due to its relatively simple structure and convenient maintenance, the number of load-carrying overhead cranes can be adjusted according to production requirements. At the same time, due to the characteristics of the chain hoist lifting of the overhead crane, the workpiece can be directly put into the chemical agent tank for cleaning treatment, so it is widely used in the pretreatment and electrocoating processes of parts such as automobile suspensions.

[0003] The overhead crane trolley wire refers to a guide rail system for power supply to the moving overhead crane, which is composed of a trolley wire guide rail (fixed part) and a current collector (sliding part). Among them, the trolley wire guide rail is connected to the power supply, the current collector is connected to the overhead crane, and the current collector can slide on the trolley wire track, take electricity by contacting the copper bar on the trolley wire guide rail, and at the same time transmit the electric energy to the overhead crane for use. In addition, the overhead crane also uses the trolley wire guide rail for signal transmission, and collects and feedback signals through the contact between the carbon brush on the trolley wire guide rail and the current collector, so as to ensure the smooth operation of the overhead crane.

[0004] In the suspension part production line, the process involves pretreatment, electrocoating and drying furnace, resulting in dust such as drying furnace ash in the workshop, making the trolley wire guide rail easy to be dirty, thus causing abnormal signal transmission or overhead crane power supply. For the cleaning of the dirty trolley wire guide rail, at present, mostly manual wiping and blowing are used. On the one hand, because the trolley wire guide rail is at a high altitude, the maintenance inspection platform is at a high position, and there are no protective measures at the edge and opening parts, the labor intensity of the operation is large during abnormal maintenance or daily cleaning and maintenance, and the construction safety risk is high. On the other hand, due to the complex environment, it is difficult for manual operation to ensure the cleaning effect, resulting in a high risk of equipment failure.

[0005] Therefore, how to reduce the labor intensity of cleaning the trolley wire guide rail and improve the safety is an urgent problem to be solved at present. Summary of the Utility Model

A first receiving groove 1211 is provided on the bracket body 121, and a second receiving groove 1221 is provided on the spring piece 122. The bracket body 121 and the spring piece 122 are detachably connected so that the first receiving groove 1211 and the second receiving groove 1221 communicate to form a limiting groove 124 for the vertical rod 111 to pass through. The groove wall of the limiting groove 124 is used to abut against the side wall of the vertical rod 111 to limit the sliding of the groove wall of the limiting groove 124 relative to the vertical rod 111. Specifically, the walking wheel bracket 230 can drive the first brush head assembly 13 to slide relative to the groove wall of the groove 2101 of the first sliding wire guide 210 through the fixing plate assembly 112, the vertical rod 111, and the first connecting bracket 12, so as to realize the automatic cleaning of the groove 2101 of the first sliding wire guide 210. In order to be able to match the application requirements of different sites and enhance the applicability of the overhead crane sliding wire guide cleaning device 100, the first brush head assembly 13 can be inserted into the groove 2101 of the first sliding wire guide 210 at different height positions. By detachably connecting the bracket body 121 and the spring piece 122, the bracket body 121 and the spring piece 122 can be installed at different positions on the vertical rod 111. When the groove wall of the limiting groove 124 abuts against the side wall of the vertical rod 111, the sliding of the groove wall of the limiting groove 124 relative to the vertical rod 111 can be restricted. In addition, in this embodiment, the vertical rod 111 is a square vertical rod, and the shape of the limiting groove 124 matches the shape of the square vertical rod, so as to increase the contact area between the groove wall of the limiting groove 124 and the side wall of the square vertical rod and improve the stability of the overhead crane sliding wire guide cleaning device 100.

A sleeve 125 is provided on the first connecting frame 12. One end of the screw rod 1311 is connected to the brush head 132, and the other end of the screw rod 1311 sequentially passes through the second nut 1312, the sleeve 125 and the third nut 1313. Both the second nut 1312 and the third nut 1313 are threadedly connected to the screw rod 1311, so that the second nut 1312 and the third nut 1313 can drive the screw rod 1311 to move relative to the sleeve 125 in the first direction. The second nut 1312 and the third nut 1313 respectively abut against both ends of the sleeve 125, so that the second nut 1312 and the third nut 1313 can limit the screw rod 1311 from moving relative to the sleeve 125 in the first direction. Specifically, when it is necessary to adjust the position of the brush head 132 in the front-rear direction, loosen the second nut 1312 and the third nut 1313, adjust the position of the screw rod 1311 relative to the sleeve 125 in the front-rear direction. After the position of the screw rod 1311 is adjusted, tighten the second nut 1312 and the third nut 1313 until the second nut 1312 and the third nut 1313 respectively abut against both ends of the sleeve 125, thereby restricting the screw rod 1311 from moving relative to the sleeve 125, so that the brush head 132 can accurately extend into the groove 2101 of the first slide rail 210.

[0043] Please refer to Figure 1 , in one embodiment, the fixing plate assembly 112 includes a first fixing plate 1121, a second fixing plate 1122 and a second fastener 1123.

The second fixing plate 1122 is connected to the vertical rod 111, and the vertical rod 111 is slidably matched with the first connecting frame 12. Specifically, by setting the first fixing plate 1121 to be slidably matched with the walking wheel bracket 230, the first fixing plate 1121 can slide up and down relative to the walking wheel bracket 230, thereby adjusting the height of the first cleaning mechanism 1, so that the brush head 132 assembly can extend into the groove 2101 of the first slide rail 210 at different height positions, enhancing the applicability of the overhead crane slide rail cleaning device 100.

[0044] In this embodiment, a chute is provided on the first fixing plate 1121. The chute extends in the up and down direction. A threaded section is provided on the walking wheel bracket 230. The second fastener 1123 includes a fourth nut. The threaded section passes through the chute and is threadedly connected to the fourth nut, so that the first fixing plate 1121 is slidably matched with the walking wheel bracket 230. The fourth nut can abut against the first fixing plate 1121 to limit the sliding of the first fixing plate 1121 relative to the walking wheel bracket 230. Specifically, the length of the chute is the sliding stroke of the first fixing plate 1121. The sliding stroke of the chute relative to the threaded section is determined by the height of the first sliding guide rail 210. Then, the fourth nut is tightened until the fourth nut abuts against the first fixing plate 1121, thereby limiting the sliding of the first fixing plate 1121 relative to the walking wheel bracket 230 and ensuring the stability of the connection of the first cleaning mechanism 1.

[0046] In addition, in this embodiment, the fixing plate assembly 112 can be made of angle iron. The cross-section of the angle iron is L-shaped, which has high bending strength and bearing capacity. The angle iron is easy to process and can adapt to various engineering requirements. The surface of the angle iron is usually treated with hot-dip galvanization, which can improve its rust prevention performance and extend its service life. Moreover, the price of the angle iron is relatively low, which is suitable for large-scale procurement and use and can effectively reduce the production cost.
