Description

Technical Field

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

[0002] Gantry crane is also called gantry crane, which is a kind of deformation of bridge crane. The metal structure of gantry crane is like a door-shaped frame. Two legs are installed under the main beam, which can walk directly on the track on the ground. Both ends of the main beam can have outward cantilever beams. It has the characteristics of high site utilization, large operating range, wide adaptability and strong versatility. It is mainly used for outdoor cargo yards, material yards and bulk cargo loading and unloading operations. The crane rails are in long-term operation, and the wheels and tracks of the crane are used for a long time. A lot of iron filings will be generated on the tracks. If they are not cleaned, the wheels of the crane will be aggravated. Therefore, in order to ensure the service life of the crane, the tracks need to be cleaned regularly; According to the Chinese patent authorization announcement number: CN116274036B, a gantry crane rail cleaning device achieves the purpose of automatic cleaning and automatic detection of crane rails. Cleaning and rail surface detection no longer require manual operation, thereby improving the degree of automation of the cleaning device, greatly reducing the labor intensity of rail surface cleaning and detection, and saving a lot of manpower and material resources. At the same time, it will also make the cleaning and detection work more efficient. The device has high versatility and operational stability, and can well meet the cleaning and detection of rails of different specifications. However, when the top surface cleaning mechanism of the above-mentioned gantry crane rail cleaning device cleans the top of the rail, the iron filings wiped off the rail are easily attached to the rail again under the rotating rolling action of the top surface roller brush, resulting in insufficient thorough cleaning of the rail.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the output shaft of the servo motor drives the first active pulley to rotate, and the first active pulley then drives the first driven pulley through the first belt, and the support rod connected to the first driven pulley rotates together with the cleaning roller, further driving the cleaning belt to rotate around the periphery of the multiple cleaning rollers to wipe and clean the top of the track. During this period, the iron filings wiped off the top of the track are firmly adsorbed on the outer wall of the cleaning belt under the magnetic force of the C-shaped permanent magnet, thereby cleaning the iron filings on the track.

[0015] 2. In the present invention, after the iron filings adsorbed on the outer wall of the cleaning belt are carried to the top position of the D-shaped magnetic conductive outer frame by the rotation of the cleaning belt, due to the C-shaped permanent magnet being set in a C-shape, when the cleaning belt carries the iron filings to the top position of the D-shaped magnetic conductive outer frame, the iron filings are just located between the top notches of the C-shaped permanent magnet, and the iron filings are not subject to the magnetic attraction of the C-shaped permanent magnet. At the same time, the output shaft of the servo motor also drives the first active bevel gear to rotate, and the first active bevel gear drives the intermediate shaft to rotate through the first driven bevel gear, thereby driving the second active pulley to rotate together, and the second active pulley drives the second driven pulley to rotate through the second belt, and further drives the conveying rod and the conveying roller connected thereto to rotate through the second driven pulley, and the conveying belt rotates under the cooperation of another conveying rod and the conveying roller, and the conveying belt rotates, and the conveying belt rotates to drive the electromagnet to rotate, and the electromagnet rotates with the conveying belt, and the iron filings moved to the top of the D-shaped magnetic conductive outer frame are adsorbed, so that the cleaning belt will not bring the iron filings wiped last time back to the track during the continuous rotation and cleaning process, thereby ensuring the track cleaning effect.

[0016] 3. In the present invention, while the electromagnet is driven to operate by the conveyor belt, the conductive rod and the elastic brush are also driven to operate synchronously. When the electromagnet with iron filings adsorbed thereon operates to the top of the unloading funnel, the elastic brush just moves to the end of the conductive sheet and separates from the conductive sheet. After that, the electricity inside the conductive sheet cannot be transmitted to the elastic brush, and then the electromagnet cannot be powered by the conductive rod, causing the electromagnet to lose its electromagnetic effect after power failure. The iron filings adsorbed on the surface of the electromagnet lose the electromagnetic adsorption effect of the electromagnet and fall to the outside through the unloading funnel, thereby automatically removing the iron filings on the surface of the electromagnet and avoiding bringing back the iron filings adsorbed last time.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-9 The technical solution provided by the present invention specifically includes the following embodiments: Embodiment 1

[0021] A gantry crane track cleaning device comprises two frames 1 arranged front and rear, and a top cleaning component 2 is arranged between the two frames 1; The top cleaning component 2 includes a fixed platform 201 fixedly installed between the two frames 1, a cleaning component housing 202 is provided at the bottom of the fixed platform 201, a C-shaped permanent magnet 203 is fixedly provided inside the cleaning component housing 202, a D-shaped magnetic conductive outer frame 204 is fixedly installed on the outer wall of the C-shaped permanent magnet 203, a plurality of equally spaced buried grooves 205 are provided on the outer wall of the D-shaped magnetic conductive outer frame 204, support rods 206 are rotatably installed inside the buried grooves 205, cleaning rollers 207 are fixedly installed on the outer walls of the support rods 206, and a cleaning belt 208 is commonly wound around the outer walls of the plurality of cleaning rollers 207; A servo motor 209 is fixedly installed inside the C-shaped permanent magnet 203, and a first driving pulley 2010 is fixedly installed on the output shaft of the servo motor 209. A first driven pulley 2011 is fixedly installed at one end of one of the support rods 206. The first driven pulley 2011 is located at the bottom of the first driving pulley 2010, and a first belt 2012 is sleeved between the first driving pulley 2010 and the first driven pulley 2011. Specifically, the output shaft of the servo motor 209 drives the first active pulley 2010 to rotate, and the first active pulley 2010 then drives the first driven pulley 2011 through the first belt 2012, and the support rod 206 connected to the first driven pulley 2011 rotates together with the cleaning roller 207, further driving the cleaning belt 208 to rotate around the periphery of the multiple cleaning rollers 207 to wipe and clean the top of the track. During this period, the iron filings wiped off the top of the track are firmly adsorbed on the outer wall of the cleaning belt 208 under the magnetic force of the C-shaped permanent magnet 203, thereby cleaning the iron filings on the track.

[0022] Furthermore, two tensioning rods 2030 distributed front and back are slidably installed on the top of the fixed table 201, and the tensioning rods 2030 pass through the interior of the fixed table 201 and extend to its bottom. The cleaning component shell 202 is fixedly installed at the bottom of the two tensioning rods 2030. The outer periphery of the tensioning rods 2030 is sleeved with tensioning springs 2031, and the tensioning springs 2031 are fixedly installed between the fixed table 201 and the cleaning component shell 202. By setting the sliding installation of the tensioning rods 2030 and the fixed table 201, the fixed table 201 can be limited, and by utilizing the elastic force of the two tensioning springs 2031, the bottom of the cleaning belt 208 can be firmly abutted against the top of the track, thereby ensuring the cleaning effect on the top of the track. Embodiment 2

[0023] Two conveying frame plates 2013 distributed left and right are fixedly installed inside the cleaning component housing 202. The two conveying frame plates 2013 are located on the top of the cleaning belt 208. Two conveying rods 2014 distributed front and back are rotatably installed between the two conveying frame plates 2013. Two conveying rollers 2015 distributed left and right are fixedly installed on the outer walls of the two conveying rods 214. A conveying belt 2016 is commonly sleeved between the two conveying rollers 2015 in the front and back directions. A plurality of electromagnets 2018 distributed at equal distances are fixedly installed on the outer wall of the conveying belt 2016. Two adapter seats 2029 distributed on the left and right are fixedly installed on the front of the C-shaped permanent magnet 203, and a central shaft 2026 is rotatably installed between the two adapter seats 2029. A first driven bevel gear 2027 is fixedly installed on the outer wall of the central shaft 2026. A first driving bevel gear 2025 is fixedly installed on the output shaft end of the servo motor 209. The first driving bevel gear 2025 is located at the front end of the first driving pulley 2010, and the first driving bevel gear 2025 is meshed with the first driven bevel gear 2027. A second driving pulley 2028 is fixedly installed on one end of the central shaft 2026, and a second driven pulley 2023 is fixedly installed on one end of one of the conveying rods 2014. The second driven pulley 2023 is located on the top of the second driving pulley 2028, and a second belt 2024 is commonly sleeved between the second driven pulley 2023 and the second driving pulley 2028; Specifically, in this embodiment, as the cleaning belt 208 rotates, the iron filings adsorbed on the outer wall of the cleaning belt 208 are carried to the top position of the D-shaped magnetic conductive outer frame 204. Since the C-shaped permanent magnet 203 is set in a C shape, when the cleaning belt 208 carries the iron filings and moves to the top position of the D-shaped magnetic conductive outer frame 204, the iron filings are just located between the top notches of the C-shaped permanent magnet 203, and the iron filings are not subject to the magnetic attraction of the C-shaped permanent magnet 203. At the same time, the output shaft of the servo motor 209 also drives the first active bevel gear 2025 to rotate, and the first active bevel gear 2025 then drives the intermediate shaft 2026 to rotate through the first driven bevel gear 2027, thereby driving the second active pulley 2028 to rotate together The second active pulley 2028 then drives the second driven pulley 2023 to rotate through the second belt 2024, and further drives the conveying rod 2014 and the conveying roller 2015 connected thereto to rotate through the second driven pulley 2023, and the conveying belt 2016 rotates under the cooperation of another conveying rod 2014 and the conveying roller 2015, and the conveying belt 2016 rotates, and the rotation of the conveying belt 2016 drives the electromagnet 2018 to rotate, and the electromagnet 2018 rotates with the conveying belt 2016, and the iron filings moved to the top of the D-shaped magnetic conductive outer frame 204 are adsorbed during the rotation of the electromagnet 2018 with the conveying belt 2016, so that the cleaning belt 208 will not bring the iron filings wiped last time back to the track during the continuous rotation and cleaning process, thereby ensuring the track cleaning effect.

[0024] It should be noted that there are two conveyor belts 2016, and the two conveyor belts 2016 are distributed on the left and right. An insulating pad 2017 is fixedly installed on the outer wall of the conveyor belt 2016, and the electromagnet 2018 is fixedly connected to the outer wall of the conveyor belt 2016 through the insulating pad 2017. A conductive rod 2019 is fixedly installed in the middle of one side of the electromagnet 2018 close to the insulating pad 2017, and the conductive rod 2019 is located between the two conveyor belts 2016. An elastic brush 2020 is fixedly installed on one end of the conductive rod 2019 away from the electromagnet 2018. Two fixed rods 2021 distributed front and back are commonly connected between the left and right walls of the cleaning component housing 202. A conductive sheet 2022 is commonly installed at the bottom of the two fixed rods 2021. The position of the conductive sheet 2022 is adapted to the position of the elastic brush 2020. The elastic brush 2020 is electrically connected to the power supply of the device. The bottom of the cleaning component housing 202 is away from the cleaning belt 208. An unloading funnel 2002 is fixedly installed at the end, and the unloading funnel 2002 is connected to the interior of the cleaning component housing 202. As the conveyor belt 2016 drives the electromagnet 2018 to operate, the conductive rod 2019 and the elastic brush 2020 are driven to operate synchronously. When the electromagnet 2018 with iron filings adsorbed runs to the top of the unloading funnel 2002, the elastic brush 2020 just moves to the end of the conductive sheet 2022 and separates from the conductive sheet 2022. Thereafter, the electricity inside the conductive sheet 2022 cannot be transmitted to the elastic brush 2020, and then the electromagnet 2018 cannot be powered by the conductive rod 2019, causing the electromagnet 2018 to lose its electromagnetic effect after power failure, and the iron filings adsorbed on the surface of the electromagnet 2018 lose the electromagnetic adsorption effect of the electromagnet 2018, and fall into the outside through the unloading funnel 2002, thereby automatically removing the iron filings on the surface of the electromagnet 2018 to avoid bringing back the iron filings adsorbed last time. Embodiment 3

[0025] The front and rear of the frame 1 are both provided with a side cleaning component 3, the side cleaning component 3 includes a side cleaning shaft 301, a side cleaning disc 302 is fixedly installed at the bottom of the side cleaning shaft 301, a plurality of telescopic holes 303 distributed at equal angles are penetrated through the outer wall of the side cleaning disc 302, a telescopic rod 304 is slidably installed inside the telescopic holes 303, a side cleaning plate 305 is fixedly installed at one end of the telescopic rod 304 away from the center of the side cleaning disc 302, and a plurality of steel wire bristles 306 distributed vertically and horizontally are fixedly installed on one side of the side cleaning plate 305 away from the telescopic rod 304; An adapter frame 309 is commonly installed at one end of the top of the two frames 1 away from the fixed platform 201, the side cleaning shaft 301 is rotatably installed inside the adapter frame 309 and extends to the bottom thereof, the front and back sides of the adapter frame 309 are rotatably installed with a walking shaft rod 3010, the position of the walking shaft rod 3010 corresponds to the position of the side cleaning shaft 301, and the end of the walking shaft rod 3010 close to the side cleaning shaft 301 is fixedly installed with a second active bevel gear 3012, the outer wall of the side cleaning shaft 301 is fixedly installed with a second driven bevel gear 308, the second driven bevel gear 308 is meshed with the second active bevel gear 3012, and the end of the walking shaft rod 3010 away from the second active bevel gear 3012 is fixedly installed with a walking roller 4; Specifically, in this embodiment, when the staff pushes the device to move along the track, the two walking rollers 4 rotate and drive the two walking shafts 3010 to rotate. The rotation of the walking shaft 3010 drives the second active bevel gear 3012 to rotate. The second active bevel gear 3012 then drives the side cleaning shaft 301 together with the side cleaning disc 302 to rotate through the second driven bevel gear 308. The rotation of the side cleaning disc 302 drives the multiple telescopic rods 304, the return spring 307 and the wire bristles 306 to rotate. Due to the action of the rotating centrifugal force, the multiple telescopic rods 304 slide toward the periphery along the inner wall of the telescopic hole 303, driving the return spring 307 and the wire bristles 306 to move together, thereby increasing the rotation radius of the wire bristles 306, contacting the side of the track, and cleaning the side wall of the track. Compared with the prior art, there is no need to adjust the spacing between the two side cleaning components 3 during use, thereby improving the convenience of using the device.

[0026] Furthermore, a return spring 307 is sleeved on the periphery of the telescopic rod 304, and the return spring 307 is fixedly installed between the side cleaning disc 302 and the side cleaning plate 305. When the telescopic rod 304 slides along the telescopic hole 303 under the action of the rotating centrifugal force, the return spring 307 is stretched and stores force, so that after cleaning, when the side cleaning shaft 301 and the side cleaning disc 302 stop rotating, the centrifugal force acting on the multiple telescopic rods 304 disappears, and the rebound force of the return spring 307 can push the telescopic rod 304, the side cleaning plate 305 and the wire bristles 306 to reset.

[0027] Furthermore, a wheel frame 5 is fixedly installed at one end of the bottom of the two frames 1 close to the fixed platform 201, and a balancing roller 501 is installed between the bottoms of the two wheel frames 5 for common rotation. A handle is fixedly provided at the top right end of the two frames 1. During use, the balancing roller 501 is placed on the top of the track, which makes it convenient for the staff to control the device through the handle, thereby improving the stability of the movement of the device.

[0028] When the gantry crane track cleaning device of the present invention is in operation, the worker first holds the two handles of the device with both hands and pushes the device to the periphery of the crane track, and places the two side cleaning components 3 on both sides of the track, and at the same time places the balancing roller 501 against the top of the track, and pushes the device to move along the track, while the top cleaning component 2 cleans the top of the track, and the two side cleaning components 3 clean the side walls of the track; Specifically, when the balancing roller 501 is against the top of the track, the bottom wall of the cleaning belt 208 contacts the top of the track, and the output shaft of the servo motor 209 drives the first active pulley 2010 to rotate, and the first active pulley 2010 drives the first driven pulley 2011 through the first belt 2012, and the support rod 206 connected to the first driven pulley 2011 rotates together with the cleaning roller 207, further driving the cleaning belt 208 to rotate around the periphery of the plurality of cleaning rollers 207, thereby balancing the top of the track. The cleaning belt 208 is used to clean the track. During the cleaning process, the iron filings wiped off the top of the track are firmly adsorbed on the outer wall of the cleaning belt 208 under the magnetic force of the C-shaped permanent magnet 203. As the cleaning belt 208 rotates, it is carried to the top position of the D-shaped magnetic conductive outer frame 204. Because the C-shaped permanent magnet 203 is C-shaped, when the cleaning belt 208 carries the iron filings and moves to the top position of the D-shaped magnetic conductive outer frame 204, the iron filings are just located between the top notches of the C-shaped permanent magnet 203, and the iron filings are not affected by the C-shaped permanent magnet 203. The magnet 203 has a magnetic attraction force. At the same time, the output shaft of the servo motor 209 also drives the first active bevel gear 2025 to rotate. The first active bevel gear 2025 then drives the transfer shaft 2026 to rotate through the first driven bevel gear 2027, thereby driving the second active pulley 2028 to rotate together. The second active pulley 2028 then drives the second driven pulley 2023 to rotate through the second belt 2024, and further drives the conveying rod 2014 and the conveying roller 2015 connected thereto to rotate through the second driven pulley 2023, and the conveying belt 2016 is rotated under the cooperation of another conveying rod 2014 and the conveying roller 2015. The conveying belt 2016 rotates and drives the electromagnet 218 to rotate. During the period when the electromagnet 218 rotates with the conveying belt 2016, the iron filings moved to the top of the D-shaped magnetic conductive outer frame 204 are adsorbed, so that the cleaning belt 208 will not bring the iron filings wiped last time back to the track during the continuous rotation and cleaning process, thereby ensuring the track cleaning effect; As the conveyor belt 216 drives the electromagnet 2018 to operate, the conductive rod 2019 and the elastic brush 2020 are driven to operate synchronously. When the electromagnet 2018 with iron filings adsorbed thereon operates to the top of the unloading funnel 2002, the elastic brush 2020 just moves to the end of the conductive sheet 2022 and separates from the conductive sheet 2022. After that, the electricity inside the conductive sheet 2022 cannot be transmitted to the elastic brush 2020, and then the electromagnet 2018 cannot be powered by the conductive rod 2019, causing the electromagnet 2018 to lose its electromagnetic effect after power failure, and the iron filings adsorbed on the surface of the electromagnet 2018 lose the electromagnetic adsorption effect of the electromagnet 2018, and fall to the outside through the unloading funnel 2002, thereby automatically removing the iron filings on the surface of the electromagnet 2018 to avoid bringing back the iron filings adsorbed last time. When the staff pushes the device to move along the track, the two walking rollers 4 rotate and drive the two walking shafts 3010 to rotate. The rotation of the walking shaft 3010 drives the second active bevel gear 3012 to rotate. The second active bevel gear 3012 then drives the side cleaning shaft 301 together with the side cleaning disc 302 to rotate through the second driven bevel gear 308. The rotation of the side cleaning disc 302 drives the multiple telescopic rods 304, the return spring 307 and the wire bristles 306 to rotate. Due to the action of the rotating centrifugal force, the multiple telescopic rods 304 slide toward the periphery along the inner wall of the telescopic hole 303, driving the return spring 307 and the wire bristles 306 to move together, thereby increasing the rotation radius of the wire bristles 306, contacting the side of the track, and cleaning the side wall of the track.
