Description

Technical Field

[0001] The utility model relates to the technical field of crane track cleaning equipment, in particular to a gantry crane track cleaning and maintenance device. Background Art

[0002] Gantry crane is a kind of door-shaped lifting machinery with cyclic and intermittent motion, mainly used for loading and unloading operations in outdoor cargo yards, storage yards and bulk cargoes. Its metal structure is like a door-shaped frame, with two legs installed under the load-bearing main beam, which can walk directly on the track on the ground, and the two ends of the main beam can have outward cantilever beams. Gantry crane is widely used in port cargo yards, open warehouses, docks, metallurgy, electric power, chemical industry and other industrial places due to its high site utilization rate, wide operating range, wide adaptability and strong versatility.

[0003] After the existing track cleaning and maintenance device cleans the track, a small amount of cleaning liquid will remain on the track. However, the cleaning liquid used by the cleaning and maintenance device contains corrosive chemical components. If it adheres to the track for a long time, it will cause the track surface to rust, making the crane move unsteadily on the track.

[0004] Therefore, a gantry crane track cleaning and maintenance device is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that residual cleaning liquid in the track easily causes the track surface to rust. The utility model provides a gantry crane track cleaning and maintenance device.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] A gantry crane track cleaning and maintenance device comprises a crane track, a fixing frame is arranged on the top of the crane track, a control mechanism is arranged on the top of the fixing frame, spraying mechanisms are fixedly connected to the left and right sides of the fixing frame, a water injection pipe is fixedly connected to the side of the spraying mechanism away from each other, a nozzle is fixedly connected to the bottom of the spraying mechanism, cleaning mechanisms are arranged on the left and right sides of the fixing frame, rubber pads are arranged on the left and right sides of the crane track, cotton cloth is arranged on the side of the rubber pads close to each other, and connecting rods are arranged on the side of the rubber pads away from each other, a moving component is arranged on the rear side of the fixing frame, and a water filter component is arranged on the rear side of the rubber pad.

[0008] Furthermore, the moving component includes side panels fixedly connected to the left and right ends of the rear side of the moving component, the outer wall surface of the side panel is fixedly connected to a stepper motor, the output end of the stepper motor is fixedly connected to a rotating shaft, the left and right ends of the rotating shaft are both provided with thread grooves with opposite rotation directions, and a cross bar is fixedly connected between the side panels.

[0009] Furthermore, the front sides of the tops of the connecting rods are respectively threadedly connected in thread grooves with opposite rotation directions, and the rear sides of the tops of the connecting rods are movably connected to the wall surface of the cross bar.

[0010] Furthermore, the water filter assembly includes two groups of fixed blocks arranged at the top and bottom of the rubber pad, an arc rod is movably connected between the fixed blocks, a rotating mechanism is arranged on the top of the fixed blocks, a first spring is fixedly connected between the fixed blocks, a through groove is opened on the wall of the fixed block, a second spring is fixedly connected inside the through groove, a circular plate is fixedly connected to the output end of the second spring, a moving block is fixedly connected to the side of the circular plate away from each other, a top block is fixedly connected to the wall of the front fixed block, and a hydraulic rod is fixedly connected to the wall of the rear fixed block.

[0011] Furthermore, the output ends of the moving block and the top block are mirror-image sloped surfaces, a slide groove is provided on the top of the rubber pad, and a slide rod is fixedly connected to the bottom of the fixed block.

[0012] Furthermore, the upper and lower sides of the connecting rod near one end of the rubber pad are fixedly connected with a connecting seat, a threaded hole is opened inside the connecting seat and a screw is threadedly connected inside the threaded hole, and a threaded hole corresponding to the position of the screw is opened on the wall of the rubber pad.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The utility model first controls the moving mechanism to drive the fixed frame to move on the top of the crane track, and the spraying mechanism sprays the cleaning liquid into the inside of the crane track through the nozzle. After the nozzle sprays the cleaning liquid, the cleaning mechanism cleans the crane track. The cleaning liquid remaining after the cleaning mechanism is cleaned can be wiped dry by placing the cotton cloth close to the left and right sides of the crane track. The distance between the rubber pads can be adjusted by the moving assembly to wipe the remaining cleaning liquid of crane tracks of different diameters. The water inside the cotton cloth can be squeezed dry by the water filter assembly, and the cotton cloth can be repeatedly used without replacement.

[0015] 2. The utility model is provided with a moving component. When facing crane rails of different diameters, the external controller is started, and the stepper motor drives the rotating shaft to rotate in the forward or reverse direction through the output end. During the rotation of the rotating shaft, the connecting rods are driven to move closer to or away from each other through the thread grooves of opposite rotation directions. The connecting rods are limited by the cross bar at the rear side of the top, so that the connecting rods move in translation, and the connecting rods are prevented from rotating around the rotating shaft, so that the connecting rods drive the rubber pad and cotton cloth to wipe the remaining cleaning liquid on crane rails of different diameters.

[0016] 3. The utility model provides a water filtering component. After the cotton cloth is continuously cleaned, the cotton cloth contains a large amount of water, which will make it impossible to wipe the remaining cleaning liquid on the crane track. The rotating mechanism is started to drive the arc rod to rotate ninety degrees, so that the inside of the arc rod fits with the wall surface of the cotton cloth. The hydraulic rod is started to push the moving block to move toward the top block through the output end. The moving block drives the through groove and the arc rod to move toward the top block through the second spring. The first spring is deformed and begins to shrink. The arc rod squeezes the water inside the cotton cloth during the movement. When the moving block fits with the top block, the second spring begins to rebound and shrink under pressure and drives the moving block to move inside the through groove. At the same time, the moving block separates from the output end of the hydraulic rod, and the first spring stops squeezing and begins to rebound. The tension of the first spring drives the rear fixed block to move rapidly backwards, and the fixed block also drives the arc rod to move backwards, so that the water inside the cotton cloth is completely squeezed out, and the remaining cleaning liquid can be wiped continuously.

[0026] like Figures 1 to 4 As shown, a gantry crane track cleaning and maintenance device includes a crane track 1, the crane track 1 is a main body, a fixing frame 2 is arranged on the top of the crane track 1, a control mechanism 3 is arranged on the top of the fixing frame 2, spraying mechanisms 4 are fixedly connected to the left and right sides of the inside of the fixing frame 2, a water injection pipe 401 is fixedly connected to the side of the spraying mechanism 4 away from each other, a nozzle 402 is fixedly connected to the bottom of the spraying mechanism 4, cleaning mechanisms 5 are arranged on the left and right sides of the inside of the fixing frame 2, rubber pads 6 are arranged on the left and right sides of the crane track 1, cotton cloth 601 is arranged on the side where the rubber pads 6 are close to each other, and connecting rods 602 are arranged on the side where the rubber pads 6 are away from each other, a moving component 7 for adjusting the distance between the rubber pads 6 is arranged on the rear side of the fixing frame 2, and a water filtering component 9 for filtering water inside the cotton cloth 601 is arranged on the rear side of the rubber pad 6.

[0027] It should be noted that, first, the control mechanism 3 controls the moving mechanism 301 to drive the fixed frame 2 to move on the top of the crane rail 1, and the spraying mechanism 4 sprays the cleaning liquid into the inside of the crane rail 1 through the nozzle 402. After the nozzle 402 sprays the cleaning liquid, the cleaning mechanism 5 cleans the crane rail 1. The cotton cloth 601 is close to the left and right sides of the crane rail 1, and the remaining cleaning liquid after the cleaning mechanism 5 is cleaned can be wiped dry. By adjusting the distance between the rubber pads 6 by the moving component 7, the remaining cleaning liquid can be wiped dry for crane rails 1 of different diameters. The water inside the cotton cloth 601 can be squeezed dry by the water filter component 9, and the cotton cloth 601 can be used repeatedly without replacement.

[0028] The moving component 7 includes side plates 701 fixedly connected to the left and right ends of the rear side of the moving component 7, the outer wall of the side plate 701 is fixedly connected to the stepper motor 702, the output end of the stepper motor 702 is fixedly connected to the rotating shaft 703, the left and right ends of the rotating shaft 703 are both provided with thread grooves 704 with opposite rotation directions, a cross bar 705 is fixedly connected between the side plates 701, the top front sides of the connecting rod 602 are respectively threadedly connected in the thread grooves 704, and the top rear sides of the connecting rod 602 are movably connected to the wall of the cross bar 705.

[0029] It should be noted that, when facing crane rails 1 of different diameters, the external controller is started, and the stepper motor 702 drives the rotating shaft 703 to rotate forward or reversely through the output end. During the rotation process, the rotating shaft 703 drives the connecting rod 602 to move closer to or away from each other through the threaded groove 704 with opposite rotation directions. The connecting rod 602 is limited by the cross bar 705 through the top rear side, so that the connecting rod 602 moves in translation, preventing the connecting rod 602 from rotating around the rotating shaft 703, thereby realizing that the connecting rod 602 drives the rubber pad 6 and the cotton cloth 601 to wipe the remaining cleaning liquid on the crane rails 1 of different diameters.

[0030] The water filter assembly 9 includes two groups of fixed blocks 901 arranged at the top and bottom of the rubber pad 6, a longitudinal arc rod 902 is movably connected between the rear fixed blocks 901, a rotating mechanism 903 is arranged on the top of the fixed blocks 901, a first spring 904 is fixedly connected between the fixed blocks 901, and a through groove 905 is provided on the side of the rear fixed blocks 901 away from each other, a second spring 906 is fixedly connected inside the through groove 905, and a circular plate 907 is fixedly connected to the output end of the second spring 906. A moving block 908 is fixedly connected to one side of the plates 907 that are away from each other, and the output end of the moving block 908 is set as a slope. A top block 909 corresponding to the position of the moving block 908 is fixedly connected to the wall surface of the front fixed block 901, and the output end of the top block 909 is set as a slope. A hydraulic rod 910 is fixedly connected to the wall surface of the rear fixed block 901, a slide groove 911 is opened on the top of the rubber pad 6, and a slide rod 912 is fixedly connected to the bottom of the fixed block 901, and the slide rod 912 is adapted to the inside of the slide groove 911.

[0031] It should be noted that after the cotton cloth 601 is continuously cleaned, the cotton cloth 601 contains a large amount of water, which makes it impossible to wipe the crane rail 1 with the remaining cleaning liquid. The rotating mechanism 903 starts to drive the arc rod 902 to rotate 90 degrees, so that the inside of the arc rod 902 fits the wall of the cotton cloth 601. The hydraulic rod 910 starts to push the moving block 908 to move toward the top block 909 through the output end. The moving block 908 drives the through groove 905 and the arc rod 902 to move toward the top block 909 through the second spring 906. The first spring 904 is deformed and begins to shrink. The arc rod 902 moves. The moisture inside the cotton cloth 601 is squeezed out during the movement process. When the moving block 908 fits with the top block 909, the second spring 906 begins to rebound and shrink under pressure and drives the moving block 908 to move toward the inside of the through groove 905. At the same time, the moving block 908 disengages from the output end of the hydraulic rod 910, and the first spring 904 stops squeezing and begins to rebound. The tension of the first spring 904 drives the rear fixed block 901 to move backward rapidly, and the fixed block 901 also drives the arc rod 902 to move backward, so that the moisture inside the cotton cloth 601 is completely squeezed out, and the remaining cleaning liquid can be wiped continuously.

[0032] The upper and lower sides of the connecting rod 602 near one end of the rubber pad 6 are fixedly connected to a connecting seat 8, a threaded hole 802 is provided inside the connecting seat 8, and a screw 801 is threadedly connected inside the threaded hole 802, and a threaded hole 802 corresponding to the position of the screw 801 is provided on the wall surface of the rubber pad 6.

[0033] It should be noted that the cotton cloth 601 may be damaged after long-term use. By rotating the screw 801 in the reverse direction to disengage the screw 801 from the threaded hole 802 , the rubber pad 6 can be taken out and the cotton cloth 601 can be replaced.

[0034] In summary: first, the control mechanism 3 controls the moving mechanism 301 to drive the fixed frame 2 to move on the top of the crane rail 1, and the spraying mechanism 4 sprays the cleaning liquid into the inside of the crane rail 1 through the nozzle 402. After the nozzle 402 sprays the cleaning liquid, the cleaning mechanism 5 cleans the crane rail 1. The cotton cloth 601 is close to the left and right sides of the crane rail 1, and the remaining cleaning liquid after the cleaning mechanism 5 is cleaned can be wiped dry. By adjusting the distance between the rubber pads 6 by the moving component 7, the remaining cleaning liquid can be wiped dry for crane rails 1 of different diameters. The water inside the cotton cloth 601 can be squeezed dry by the water filter component 9, and the cotton cloth 601 can be reused without replacement.
