[0017] Figure 3 This is a view of the actual operating position of the present invention. DETAILED DESCRIPTION

[0018] The specific implementation of the present utility model is further described below with reference to the accompanying drawings.

[0019] like Figure 1 、 2 As shown in Figure 3, the bridge crane travel track surface cleaning device of the present invention is characterized in that it includes a cylinder 1, a cleaning rubber 2 arranged in this cylinder 1, a pressure cover 6 arranged on the upper part of this cylinder 1, two adjusting screws 9 arranged in the middle of this pressure cover 6, and a compensation spring 4 respectively arranged on each adjusting screw 9. This compensation spring 4 presses on the upper surface of the cleaning rubber 2 so that the lower surface of the cleaning rubber 2 is tightly attached to the rail surface of the rail 14.

[0020] The cylinder 1 is in the shape of a cuboid, and the cleaning rubber 2 is in the shape of a cuboid.

[0021] The adjusting screw 9 is fastened to the gland via the adjusting screw fixing nut 8 , and a spring flat washer 5 is welded at the middle position of the adjusting screw 9 .

[0022] The lower part of the cleaning rubber 2 is provided with three 10 mm wide color rings, namely a green color ring, a yellow color ring and a red color ring.

[0023] The two sides of the pressure cover 6 are respectively provided with an upper cover fastening screw and an upper cover fastening nut 3.

[0024] The utility model provides a bridge crane running track surface cleaning device comprising a cylinder 1, a pressure cover 6 and a cleaning rubber 2.

[0025] The cylinder 1 is welded from 8mm thick steel plates into a cylindrical structure, so that the cleaning rubber 2 can move up and down in the cylinder.

[0026] The cleaning rubber 2 converts the pressure between its lower surface and the rail surface 14 into friction with the rail surface 14, thereby cleaning the dust on the rail surface 14.

[0027] The pressure cover 6 utilizes the adjusting screw 9 and the compensation spring 4 thereon to squeeze the upper surface of the cleaning rubber 2, so that the lower surface of the cleaning rubber 2 and the rail surface 14 maintain a high pressure, ensuring that the cleaning rubber 2 has a good cleaning effect on the dust on the rail surface 14. The replacement of the cleaning rubber 2 is convenient by removing the pressure cover 6.

[0028] A rectangular cylinder 1 with an inner hole of 150×18×200 mm is made from an 8 mm thick steel plate, and a rectangular cleaning rubber 2 of 148×16×180 mm is inserted into the cylinder.

[0029] Use 8 mm thick steel plate to make a 214×34 mm rectangular plate as the pressure cover 6, drill two holes with a spacing of 190 mm and a diameter of 12 mm on both sides of the pressure cover 6, and drill two threaded holes with a spacing of 90 mm and a diameter of 8 mm in the middle. Use an M8×100 screw as the adjusting screw 9 to pass through the M8 screw hole on the pressure cover 6, weld a 16 mm diameter flat washer as the spring flat washer 5 in the middle position of the adjusting screw 9, and use a spring with a wire diameter of 3 mm and a specification of 3×16×100 mm as the compensation spring 4, and wear it on the adjusting screw 9.

[0030] Use M10 screw and nut to fix it on the cylinder 1 through the M12 hole on the cylinder cover 6, and use the compensation spring 4 on the cylinder cover 6 to press the upper surface of the cleaning rubber 2 in the cylinder 1 so that the lower surface of the cleaning rubber 2 is in close contact with the rail 14.

[0031] When the bridge crane is moving, the friction between the lower surface of the cleaning rubber 2 in the cylinder 1 and the surface of the rail 14 is used to wipe off the dust on the surface of the rail 14. After the cleaning rubber 2 is worn, the cleaning rubber 2 moves downward under the action of the compensation spring 4 to ensure the fit and pressure between the lower surface of the cleaning rubber 2 and the surface of the rail 14. The contact pressure between the cleaning rubber 2 and the surface of the rail 14 is adjusted through two M8 adjustment screws 9 on the upper cover of the cylinder to ensure good contact between the bridge crane wheel 13 and the surface of the rail 14.

[0032] On the surface of the cleaning rubber 2 in the cylinder 1, three 10 mm wide color rings are sprayed 35 mm upward from the bottom, namely green color ring 10, yellow color ring 11 and red color ring 12. The color of the cleaning rubber 2 exposed at the bottom of the cylinder 1 can be used to know the degree of wear of the cleaning rubber 2, ensuring that the cleaning rubber 2 can be adjusted and replaced in time.

[0033] Example 1:

[0034] 1. Weld a 10# channel steel 15 on the front body of the bridge crane rail wheel. The bottom of the channel steel 15 should be 30 mm away from the rail surface 14.

[0035] 2. Weld the rail cleaning device to the bottom of the channel steel 15 so that the lower surface of the cleaning rubber 2 in the rail cleaning device is in close contact with the rail surface 14.

[0036] 3. After the cleaning rubber 2 is worn, the cleaning rubber 2 is moved downward by the action of the compensation spring 4 to ensure the fit and pressure between the lower surface of the cleaning rubber 2 and the rail 14. When the cleaning rubber 2 leaks a green ring 10, it means that the cleaning rubber 2 has been worn 5 mm. It is necessary to adjust the two M8 adjustment screws 9 of the cylinder gland 6 downward by 10 mm and lock them by adjusting the screw fixing nut 8 to improve the fit and pressure between the lower surface of the cleaning rubber 2 and the rail 14. When the cleaning rubber 2 leaks a yellow ring 11, it means that the cleaning rubber 2 has been worn 15 mm, it is necessary to adjust the two M8 adjusting screws 9 of the cylinder cover and move them downward 10 mm and lock them by adjusting the screw fixing nut 8 to ensure the fit and pressure between the lower surface of the cleaning rubber 2 and the rail 14. When the red color ring 12 leaks out of the cleaning rubber 2, it means that the cleaning rubber 2 has been worn for 25 mm and has reached the service limit of the cleaning rubber 2. The cleaning rubber 2 needs to be replaced.

[0037] Example 2:

[0038] Due to the high dust content on site, the dust was scattered on the rail surface of rail 14 and repeatedly rolled over, resulting in poor contact between the wheels of the bridge crane in the iron ore separation and crushing operation area and the rails. To solve this problem, a bridge crane travel track surface cleaning device was used to clean the rail surface.

[0039] The specific steps are as follows:

[0040] 1. First, weld a 10# channel steel 15 on the front body of the bridge crane rail wheel. The bottom of the channel steel 15 should be 30 mm away from the rail surface 14.

[0041] 2. Weld the rail cleaning device to the bottom of the channel steel 15 so that the lower surface of the cleaning rubber 2 in the rail cleaning device is in close contact with the rail surface 14.

[0042] 3. After the cleaning rubber 2 is worn, the cleaning rubber 2 is moved downward under the action of the compensation spring 4 to ensure the fit and pressure between the lower surface of the cleaning rubber 2 and the rail surface 14. When the cleaning rubber 2 leaks the green color ring 10, it means that the cleaning rubber 2 has been worn 5 mm. It is necessary to adjust the two M8 adjustment screws of the cylinder cover 6 to move downward 10 mm and lock them by adjusting the screw fixing nut 8 to improve the fit and pressure between the lower surface of the cleaning rubber 2 and the rail surface 14.

[0043] Example 3:

[0044] The bridge cranes in the Qidashan Iron Mine's crushing area generate induced and static electricity during operation, leaving nowhere for them to dissipate. This discharge can affect maintenance personnel as they hook, unhook, and stabilize components, posing a safety hazard. To address this issue, a bridge crane track cleaning device was implemented to clean the track surface.

[0045] The specific steps are as follows:

[0046] 1. First, weld a 10# channel steel 15 on the front body of the bridge crane rail wheel. The bottom of the channel steel 15 should be 30 mm away from the rail surface.

[0047] 2. Weld the rail cleaning device to the bottom of the channel steel 15 so that the lower surface of the cleaning rubber 2 in the rail cleaning device is in close contact with the rail surface 14.

[0048] 3. After the cleaning rubber 2 is worn, the cleaning rubber 2 is moved downward under the action of the compensation spring 4 to ensure the fit and pressure between the lower surface of the cleaning rubber 2 and the rail surface 14. When the yellow ring 11 leaks out of the cleaning rubber 2, it means that the cleaning rubber 2 has been worn for 15 mm. It is necessary to adjust the two M8 adjusting screws 9 of the cylinder cover 6 and move them downward for another 10 mm and lock them with the adjusting screw fixing nut 8 to ensure the fit and pressure between the lower surface of the cleaning rubber 2 and the rail surface 14.
