Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rail foreign matter removal, and in particular to a gantry crane rail foreign matter automatic removal device. BACKGROUND

[0002] In industrial production, as the key equipment for material handling, the cleaning condition of the running track of the gantry crane is directly related to the stability and safety of the equipment operation. With the continuous expansion of production scale, the operation frequency of the gantry crane continues to increase, and the problem of accumulation of foreign matters on the track is becoming more and more serious.

[0003] The track of the gantry crane is exposed to a complex working environment for a long time, and is prone to accumulate various foreign matters. The bulk material and dust generated during production and transportation will gradually accumulate in the track groove; in the outdoor environment, the accumulation of rain, snow and ice, and the sundries blown by the wind will all adhere to the track. These foreign matters not only accelerate the wear of the wheel set of the gantry crane and the track, greatly shorten the service life of the equipment, increase the maintenance cost, but also may cause the gantry crane to run out of track in extreme cases, causing serious safety accidents and causing great loss to personnel and property.

[0004] The current traditional track cleaning method has significant limitations. First, some simple cleaning devices are only equipped with a single-direction brush, for example, only the top surface of the track can be simply wiped, and the rust layer and adhered oil stains on the side surface of the track cannot be reached, resulting in obvious blind area in cleaning. Second, when manually using a high-pressure water gun to wash, although the surface dust can be removed, the impact force of the water flow is difficult to control accurately, and small sand particles and metal debris in the track groove are easily washed to the end of the track or the gap, forming secondary accumulation, which still needs to be cleaned manually, resulting in low work efficiency and high labor intensity.

The first gear 303 is in meshing transmission cooperation with the first rack 302 on the corresponding side. The first motor 202 is installed on the top of the rotating block 201 through bolts. The output shaft of the first motor 202 penetrates through the inside of the rotating block 201 and is in transmission connection with the top end of the vertical rolling brush 203. The vertical rolling brush 203 is driven to rotate by the first motor 202. The protective cover 206 is fixedly installed on the lower part of the lifting frame 105 in a left-right symmetrical manner. The protective cover 206 is arranged on the upper half of the horizontal rolling brush 207.

The second motor 205 is installed on the front side of the lower part of the lifting frame 105 in a left-right symmetrical manner through bolts. The output shaft of the second motor 205 is in transmission connection with the front end of the horizontal rolling brush 207 on the corresponding side. The horizontal rolling brush 207 is driven to rotate by the second motor 205.

[0034] When the gantry crane track 1 cleaning operation is performed, the device is pre-positioned with the track 1 through the pulley moving group 102, and the pulley moving group 102 is driven by an external power source to drive the device to move linearly along the track 1; at this time, the vertical roller brush 203 is attached to the front and rear sides of the track 1, and the horizontal roller brush 207 is attached to the top surface of the track 1. The first motor 202 and the second motor 205 are started synchronously through the external control system, the output shaft of the first motor 202 drives the vertical roller brush 203 to rotate at high speed to remove the attached foreign matter on the side of the track 1, and the output shaft of the second motor 205 drives the horizontal roller brush 207 to rotate at high speed to remove the scattered foreign matter on the top surface of the track 1, realizing the synchronous cleaning of the track 1 in multiple dimensions. After the cleaning operation is completed, the electric push rod 103 is started through the control system, the telescopic rod of the electric push rod 103 is retracted to drive the lifting frame 105 to displace upward along the sliding rail 104, and the horizontal roller brush 207 and the protective cover 206 are driven to separate from the top surface of the track 1; at the same time, the lifting frame 105 drives the first rack 302 to rise synchronously through the connecting rod 301, the first rack 302 and the first gear 303 are meshed and driven to drive the rotating block 201 to drive the vertical roller brush 203 to turn upward by 180°, so that the vertical roller brush 203 is switched from the working position attached to the side of the track 1 to the storage position facing upward. The storage operation can reduce the overall space occupied by the device, facilitate disassembly from the track 1 and storage later, and when the operation is performed again, the device is installed on the track 1 through the pulley moving group 102, the telescopic rod of the electric push rod 103 is driven to extend to drive the lifting frame 105 to move downward, and the horizontal roller brush 207 is reset to attach to the top surface of the track 1; at the same time, the first rack 302 moves downward with the lifting frame 105, and the rotating block 201 is driven by the first gear 303 and the first rack 302 to drive the vertical roller brush 203 to turn downward by 180° and reset to the working position, so that the cleaning operation can be started.

[0035] Example 2: Based on example 1, as Figures 6-11As shown, it also includes a delivery pipe 401, a conveying pipe 402, a U-shaped pipe 403, a spray head 404, a fixed spray pipe 405 and a half moon baffle 407, the middle part of the mounting plate 101 is symmetrically connected with the delivery pipe 401 through the sliding connection, the delivery pipe 401 penetrates the lifting frame 105 and is rigidly fixed with the lifting frame 105, the lower end of the delivery pipe 401 is rotatably connected with the conveying pipe 402 through a swivel collar, the conveying pipe 402 is rotatably connected with the U-shaped pipe 403, the U-shaped pipe 403 is arrayed with a plurality of spray heads 404 along the vertical length direction at the front and rear ends, the spray heads 404 are arranged in double rows, one row of the spray heads 404 is directed to the inner side wall of the track 1, and the other row of the spray heads 404 is directed to the outer peripheral surface of the vertical roller brush 203, the U-shaped pipe 403 is rotatably connected with the fixed spray pipe 405 through a rotary joint and the two are in fluid communication, the fixed spray pipe 405 penetrates the inside of the protective cover 206 and its nozzle is directed to the outer peripheral surface of the horizontal roller brush 207, the half moon baffle 407 is fixedly connected in the conveying pipe 402, the half moon baffle 407 is located in the upper half part of the conveying pipe 402, a cavity is left between the half moon baffle 407 and the conveying pipe 402, the delivery pipe 401 is in fluid communication with the cavity, and the water inlet groove 406 is arranged in the bottom surface of the pipe section of the U-shaped pipe 403 inside the conveying pipe 402, and the fluid in the cavity can enter the inside of the U-shaped pipe 403 through the water inlet groove 406.

[0036] As shown in Figure 1 and Figures 6-8 As shown, it also includes a water storage frame 501, a pressure pump 502, a second rack 503 and a second gear 504, the water storage frame 501 is bolted to the top center of the mounting plate 101, a one-way water filling valve is arranged on the rear side of the water storage frame 501 for supplementing cleaning medium into the water storage frame 501, the pressure pump 502 is bolted to the right top of the water storage frame 501, the upper ends of the two delivery pipes 401 are sealingly penetrated into the inside of the water storage frame 501, a connecting ring is fixedly installed in the water storage frame 501 at a position corresponding to the delivery pipe 401, the connecting ring is in sliding sealing cooperation with the corresponding delivery pipe 401 to play a guiding and limiting role, the second rack 503 is welded to the outer side surface of the sliding rail 104, and the second gear 504 is keyed to the upper part of the U-shaped pipe 403 at the front and rear ends, the second gear 504 is in meshing transmission cooperation with the second rack 503.

[0037] The cleaning liquid is injected into the water storage frame 501 through a one-way water injection valve. During operation, the pressurizing pump 502 is started. The pressure provided by the pressurizing pump 502 overcomes the resistance along the pipeline and the outlet resistance of the spray head 404, so that the cleaning liquid is delivered to the chamber of the delivery pipe 402 through the delivery pipe 401. The cleaning liquid in the chamber enters the U-shaped pipe 403 and the fixed spray pipe 405 through the water inlet groove 406, and is finally sprayed from the spray opening of the fixed spray pipe 405 and the array spray head 404. The spray direction of the fixed spray pipe 405 points to the outer circumferential surface of the horizontal roller brush 207, so as to realize wet cleaning and lubrication of the horizontal roller brush 207. The double-row spray head 404 of the U-shaped pipe 403 respectively targets the vertical roller brush 203 and the front and rear walls of the track 1 for spray, so as to form a liquid force auxiliary cleaning effect and significantly improve the removal efficiency of stubborn stains. After the cleaning operation is completed, the pressurizing pump 502 is turned off to stop the liquid supply. When the electric push rod 103 drives the lifting frame 105 to rise, the U-shaped pipe 403 and the attached components are synchronously lifted upward, and the delivery pipe 401 and the delivery pipe 402 are synchronously lifted upward with the lifting frame 105. At this time, the second gear 504 rotates due to the meshing relationship with the second rack 503, and drives the U-shaped pipe 403 and the spray head 404 to overturn 180° upward. During the overturning process, the water inlet groove 406 of the U-shaped pipe 403 gradually abuts against the half-moon baffle 407 to form a sealing fit, thereby cutting off the flow path of the cleaning liquid from the chamber of the delivery pipe 402 to the U-shaped pipe 403, and realizing automatic closing of the waterway. After the overturning is completed, the U-shaped pipe 403 and the spray head 404 are in an upward state, which effectively reduces the storage volume of the device, facilitates disassembly and storage of the track 1, and when the device is used again, the electric push rod 103 drives the lifting frame 105 to move downward, and the U-shaped pipe 403 and the spray head 404 are driven to move downward by 180° through the meshing transmission of the second gear 504 and the second rack 503. At this time, the water inlet groove 406 is separated from the half-moon baffle 407, the flow path of the cleaning liquid is reopened, and the pressurizing pump 502 is started to restore normal liquid supply.

[0038] As shown in Figures 6-9 The support block 601 is fixedly connected to the inside of the water storage frame 501 near the delivery pipe 401. The sealing block 602 is slidably connected to the inside of the support block 601. The connecting ring on the delivery pipe 401 is connected to the sealing block 602 through the tensile spring 603. In the initial state, the tensile spring 603 is in a pre-tensioned state, and the sealing block 602 is limited to the initial position by the support block 601. The top opening of the delivery pipe 401 is in a conductive state, i.e., the working state of the device.

[0039] When the track 1 cleaning operation is completed, the electric push rod 103 drives each component to move up and be stored, and the conveying pipe 401 moves up synchronously with the lifting frame 105; at this time, the sealing block 602 remains in the initial position under the elastic tension of the tension spring 603, and the top opening of the conveying pipe 401 gradually forms a clamping fit with the sealing block 602 during the upward movement of the conveying pipe 401, the sealing block 602 is pushed by the conveying pipe 401 to slide upward along the support block 601, the elastic restoring force of the tension spring 603 keeps the sealing block 602 always under pressure, and finally the top opening of the conveying pipe 401 is sealed and blocked, and the fluid passage from the water storage frame 501 to the conveying pipe 401 is cut off; when the next cleaning operation is started, the electric push rod 103 drives each component to move down and unfold, and the conveying pipe 401 moves down to make the top opening of the conveying pipe 401 disengage from the sealing block 602, the sealing block 602 is reset by the support block 601, and the cleaning liquid in the water storage frame 501 resumes normal supply to the conveying pipe 401.

[0041] As shown in Figure 1 , Figure 12 and Figure 13 , it further comprises a lubricating oil tank 801 and a dropper 802, the top left of the mounting plate 101 is fixedly connected with the lubricating oil tank 801 through bolts, the bottom of the lubricating oil tank 801 is fixedly connected and communicated with two droppers 802, the droppers 802 vertically penetrate the mounting plate 101, and the lower ends of the droppers 802 are opposite to the top surface of the rubber block 702, and flow control valves are installed at the lower ends of the droppers 802 to adjust the dripping rate of the lubricating oil.

[0042] The special lubricating oil is injected into the oil tank 801, and when the device moves along the track 1 from left to right for cleaning, the flow control valve is opened synchronously, and the lubricating oil in the oil tank 801 is dropped to the top surface of the rubber block 702 through the dropper 802. During the movement of the device, the right scraper 703 first pre-removes the solidified oil stains and stubborn dirt on the top surface of the track 1 to achieve primary cleaning; then the horizontal roller brush 207 deeply brushes the top surface of the track 1; finally, the left rubber block 702 uniformly applies the lubricating oil to the cleaned top surface of the track 1 to form a protective film to realize the maintenance function, and the design of the buffer spring 704 can always keep the rubber block 702 and the scraper 703 in reliable contact with the top surface of the track 1, while absorbing the vibration impact during the movement, thereby ensuring the stability of the cleaning and maintenance effect. After the operation is completed, the flow control valve is closed to stop the supply of lubricating oil.
