Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a bridge-gantry crane rail cleaning device. Background Art

[0002] A gantry crane, also known as a gantry hoist, is a deformation of a bridge crane. The metal structure of the gantry crane is like a portal frame. Two support legs are installed under the load-bearing main beam, and it can directly run on the ground track. The two ends of the main beam can have outstretched cantilever beams. It has the characteristics of high site utilization rate, large operation range, wide adaptability, strong versatility, etc. It is mainly used for the loading and unloading operations of outdoor freight yards, material yards, and bulk goods. During the long-term operation of the crane rails, the wheels of the crane and the rails are used for a long time, and a large amount of iron filings will be generated on the rails. If not cleaned, the wear of the crane wheels will be aggravated. Therefore, in order to ensure the service life of the crane, the rails need to be cleaned regularly;

[0003] According to the authorization announcement number of the Chinese patent: CN116274036B, a bridge-gantry crane rail cleaning device realizes the purpose of automatically cleaning and automatically detecting the crane rails. The cleaning and rail surface detection work no longer requires manual operation. Therefore, the automation degree of the cleaning device can be improved, the labor intensity of the rail surface cleaning and detection work can be greatly reduced, and a lot of manpower and material resources can be saved. At the same time, the cleaning and detection work will be more efficient, and the device has high versatility and operation stability, and can well meet the cleaning and detection work of different specifications of rails. However, when the top surface cleaning mechanism of the above bridge-gantry crane rail cleaning device cleans the top of the rail, the iron filings wiped off from the rail are easily attached to the rail again under the rotation and rolling action of the top surface roller brush, resulting in incomplete cleaning of the rail. Summary of the Invention

[0004] Therefore, the present invention provides a bridge-gantry crane rail cleaning device to solve the above problems.

The end of the output shaft of the servo motor is fixedly installed with a first driving bevel gear. The first driving bevel gear is located at the front end of the first driving pulley, and the first driving bevel gear meshes with the first driven bevel gear. One end of the middle rotating shaft is fixedly installed with a second driving pulley. One end of one of the conveying rods is fixedly installed with a second driven pulley.

[0011] As a preferred embodiment of the present invention, there are two conveyor belts, and the two conveyor belts are distributed left and right. An insulating pad is fixedly installed on the outer wall of the conveyor belt. The electromagnet is fixedly connected to the outer wall of the conveyor belt through the insulating pad. A conductive rod is fixedly installed in the middle of the side of the electromagnet close to the insulating pad. The conductive rod is located between the two conveyor belts. One end of the conductive rod far from the electromagnet is fixedly installed with an elastic brush. Two fixing rods distributed front and back are commonly connected between the left wall and the right wall of the cleaning component housing. A conductive sheet is commonly installed at the bottom of the two fixing rods. The position of the conductive sheet is adapted to the position of the elastic brush. The elastic brush is electrically connected to the device power supply.

[0012] As a preferred embodiment of the present invention, a discharge funnel is fixedly installed at one end of the bottom of the cleaning component housing far from the cleaning belt. The discharge funnel is communicated with the inside of the cleaning component housing.

[0013] As a preferred embodiment of the present invention, a transfer frame is commonly installed at one end of the tops of the two vehicle frames far from the fixed platform. The side cleaning shaft is rotatably installed inside the transfer frame and extends to its bottom. A walking shaft rod is rotatably installed on the front and back of the transfer frame.

[0014] As a preferred embodiment of the present invention, a return spring is sleeved around the outer periphery of the telescopic rod. The return spring is fixedly installed between the side cleaning disc and the side cleaning plate.

[0015] As a preferred embodiment of the present invention, wheel frames are fixedly installed at one end of the bottoms of the two vehicle frames close to the fixed platform. A balance roller is rotatably installed between the bottoms of the two wheel frames.

[0016] As a preferred embodiment of the present invention, grips are fixedly provided at the right ends of the tops of the two frames.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. In the present invention, the output shaft of the servo motor drives the first driving pulley to rotate. The first driving pulley then drives the first driven pulley through the first belt, and the support rod connected to the first driven pulley together with the cleaning roller rotates, further driving the cleaning belt to rotate around the periphery of multiple cleaning rollers to wipe and clean the top of the track. During this period, the iron filings wiped off from 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.

[0019] 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 setting of the C-shaped permanent magnet, 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 affected by the magnetic suction force of the C-shaped permanent magnet. At the same time, the output shaft of the servo motor also drives the first driving bevel gear to rotate. The first driving bevel gear then drives the middle rotating shaft to rotate through the first driven bevel gear, and further drives the second driving pulley to rotate together. The second driving pulley then 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 conveyor belt rotates under the cooperation of another conveying rod and conveying roller. The rotation of the conveyor belt drives the electromagnet to rotate. During the rotation of the electromagnet with the conveyor belt, the iron filings moving to the top of the D-shaped magnetic conductive outer frame are adsorbed, so that during the continuous rotation and cleaning of the cleaning belt, the iron filings wiped last time will not be brought back to the track again, ensuring the cleaning effect of the track.

[0020] 3. In the present invention, during the operation of driving the electromagnet by the conveyor belt, the conductive rod and the elastic brush are synchronously driven. When the electromagnet adsorbed with iron filings rotates to the top of the unloading hopper, the elastic brush just moves to the end of the conductive sheet and separates from the conductive sheet. After that, the electric quantity inside the conductive sheet cannot be transmitted to the elastic brush, and thus cannot supply power to the electromagnet through the conductive rod, resulting in the power failure of the electromagnet and the loss of the electromagnetic effect. The iron filings adsorbed on the surface of the electromagnet lose the electromagnetic adsorption effect of the electromagnet and fall into the outside through the unloading hopper, thereby automatically removing the iron filings on the surface of the electromagnet and preventing the iron filings adsorbed last time from being brought back again.

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-9 , the technical solutions provided by the present invention specifically include the following embodiments: Embodiment 1

[0033] A bridge-gantry crane rail cleaning device includes two frames 1 distributed front and back, and a top cleaning component 2 is provided between the two frames 1;

[0034] 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 installed inside the cleaning component housing 202. A D-shaped magnetic conduction outer frame 204 is fixedly installed on the outer wall of the C-shaped permanent magnet 203. A plurality of equally spaced embedding grooves 205 are formed on the outer wall of the D-shaped magnetic conduction outer frame 204. Support rods 206 are rotatably installed inside the embedding grooves 205. Cleaning rollers 207 are fixedly installed on the outer walls of the support rods 206. A cleaning belt 208 is wound around the outer walls of the plurality of cleaning rollers 207 together;

[0035] A servo motor 209 is fixedly installed inside the C-shaped permanent magnet 203. 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. A first belt 2012 is sleeved between the first driving pulley 2010 and the first driven pulley 2011;

[0036] Specifically in this embodiment, the output shaft of the servo motor 209 drives the first driving pulley 2010 to rotate. The first driving 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 together with the cleaning roller 207 to rotate, further driving the cleaning belt 208 to rotate around the periphery of the plurality of cleaning rollers 207 to wipe and clean the top of the rail. During this period, the iron filings wiped off from the top of the rail 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 rail.

[0037] Further, two tension rods 2030 distributed front and back are slidably installed on the top of the fixed table 201. The tension rods 2030 penetrate through the inside of the fixed table 201 and extend to its bottom. The cleaning component housing 202 is fixedly installed at the bottom of the two tension rods 2030. Tension springs 2031 are sleeved on the peripheries of the tension rods 2030. The tension springs 2031 are fixedly installed between the fixed table 201 and the cleaning component housing 202. By setting the sliding installation of the tension rods 2030 and the fixed table 201, the fixed table 201 etc. can be limited. And by the elastic force of the two tension springs 2031, the bottom of the cleaning belt 208 can be firmly abutted against the top of the track, ensuring the cleaning effect on the top of the track. Embodiment 2

[0038] 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 at 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 2014. A conveyor belt 2016 is jointly sleeved between the two conveying rollers 2015 in the front and back direction. A plurality of electromagnets 2018 are fixedly arranged on the outer wall of the conveyor belt 2016 at equal distances;

[0039] Two adapter seats 2029 distributed left and right are fixedly installed on the front of the C-shaped permanent magnet 203. A middle rotating 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 middle rotating shaft 2026. A first driving bevel gear 2025 is fixedly installed at the end of the output shaft of the servo motor 209. The first driving bevel gear 2025 is located in front of the first driving belt pulley 2010, and the first driving bevel gear 2025 meshes with the first driven bevel gear 2027. A second driving belt pulley 2028 is fixedly installed at one end of the middle rotating shaft 2026. A second driven belt pulley 2023 is fixedly installed at one end of one of the conveying rods 2014. The second driven belt pulley 2023 is located on the top of the second driving belt pulley 2028. A second belt 2024 is jointly sleeved between the second driven belt pulley 2023 and the second driving belt pulley 2028;

[0040] 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. Due to the C-shaped arrangement of the C-shaped permanent magnet 203, when the cleaning belt 208 carries the iron filings 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 magnetic suction force of the C-shaped permanent magnet 203. At the same time, the output shaft of the servo motor 209 drives the first driving bevel gear 2025 to rotate, and the first driving bevel gear 2025 drives the middle rotating shaft 2026 to rotate through the first driven bevel gear 2027, thereby driving the second driving pulley 2028 to rotate together. The second driving pulley 2028 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. With the cooperation of another conveying rod 2014 and conveying roller 2015, the conveyor belt 2016 rotates. The rotation of the conveyor belt 2016 drives the electromagnet 2018 to rotate. During the rotation of the electromagnet 2018 with the conveyor belt 2016, the iron filings moving to the top of the D-shaped magnetic conductive outer frame 204 are adsorbed, so that during the continuous rotation and cleaning of the cleaning belt 208, the iron filings wiped last time will not be brought back to the track again, ensuring the cleaning effect of the track.

[0041] It should be noted that there are two conveyor belts 2016, which are distributed left and right. An insulating pad 2017 is fixedly installed on the outer wall of the conveyor belt 2016. 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. The conductive rod 2019 is located between the two conveyor belts 2016. An elastic brush 2020 is fixedly installed at one end of the conductive rod 2019 away from the electromagnet 2018. Two fixing rods 2021 distributed front and back are commonly connected between the left wall and the right wall of the cleaning component housing 202. A conductive sheet 2022 is installed at the bottom of the two fixing 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 device power supply. An unloading funnel 2002 is fixedly installed at one end of the bottom of the cleaning component housing 202 away from the cleaning belt 208. The unloading funnel 2002 is communicated with the inside of the cleaning component housing 202. During the operation of the electromagnet 2018 driven by the conveyor belt 2016, the conductive rod 2019 and the elastic brush 2020 are synchronously driven to operate. When the electromagnet 2018 adsorbed with iron filings rotates 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 electric quantity inside the conductive sheet 2022 cannot be transmitted to the elastic brush 2020, and then the electromagnet 2018 cannot be powered through the conductive rod 2019, resulting in the loss of the electromagnetic effect of the electromagnet 2018 after power failure. 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, so as to automatically remove the iron filings on the surface of the electromagnet 2018 and avoid bringing back the iron filings adsorbed last time. Embodiment III

[0042] Side cleaning components 3 are provided at both the front and the rear of the vehicle frame 1. 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 equally angularly distributed telescopic holes 303 are penetrated on the outer wall of the side cleaning disc 302. Telescopic rods 304 are slidably installed inside the telescopic holes 303. Side cleaning plates 305 are fixedly installed at one ends of the telescopic rods 304 away from the center of the side cleaning disc 302. A plurality of horizontally and vertically distributed steel wire brushes 306 are fixedly installed on one side of the side cleaning plate 305 away from the telescopic rod 304;

[0043] At one end of the top of the two vehicle frames 1 away from the fixed platform 201, a transfer frame 309 is commonly installed. The side cleaning shaft 301 is rotatably installed inside the transfer frame 309 and extends to its bottom. The front and back of the transfer frame 309 are both rotatably installed with walking shaft rods 3010. The positions of the walking shaft rods 3010 correspond to the position of the side cleaning shaft 301. And at one end of the walking shaft rod 3010 close to the side cleaning shaft 301, a second driving bevel gear 3012 is fixedly installed. On the outer wall of the side cleaning shaft 301, a second driven bevel gear 308 is fixedly installed. The second driven bevel gear 308 meshes with the second driving bevel gear 3012. At the end of the walking shaft rod 3010 away from the second driving bevel gear 3012, a walking roller 4 is fixedly installed.

[0044] Specifically in this embodiment, during the period when the staff pushes the device to move along the track, the two walking rollers 4 rotate and drive the two walking shaft rods 3010 to rotate. The rotation of the walking shaft rod 3010 drives the second driving bevel gear 3012 to rotate. The second driving 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 plurality of telescopic rods 304, the return springs 307 and the wire brush hairs 306 to rotate. Due to the action of the rotational centrifugal force, the plurality of telescopic rods 304 slide outward along the inner wall of the telescopic holes 303, driving the return springs 307 and the wire brush hairs 306 to move together. Thus, the rotation radius of the wire brush hairs 306 becomes larger and contacts the side of the track, cleaning the side wall of the track. Compared with the prior art, during use, there is no need to adjust the distance between the two side cleaning components 3, improving the convenience of use of the device.

[0045] Further, return springs 307 are sleeved on the outer periphery of the telescopic rods 304. The return springs 307 are fixedly installed between the side cleaning disc 302 and the side cleaning plate 305. When the telescopic rods 304 slide along the telescopic holes 303 under the action of the rotational centrifugal force, the return springs 307 are stretched and store energy. So that after the cleaning is completed, when the side cleaning shaft 301 and the side cleaning disc 302 stop rotating, the centrifugal force acting on the plurality of telescopic rods 304 disappears, and the return force of the return springs 307 can push the telescopic rods 304, the side cleaning plate 305 and the wire brush hairs 306 to reset.

[0046] Further, at one end of the bottom of the two vehicle frames 1 close to the fixed platform 201, wheel frames 5 are both fixedly installed. Between the bottoms of the two wheel frames 5, a balance roller 501 is rotatably installed in common. At the right ends of the tops of the two vehicle frames 1, grips are both fixedly provided. During use, by placing the balance roller 501 on the top of the track, it is convenient for the staff to control the device through the grips, improving the stability of the device movement.

[0047] When the bridge and gantry crane track cleaning device of this solution is working, first, the staff hold the two grips of the device with both hands and push the device to the periphery of the crane track, making the two side cleaning components 3 on both sides of the track. At the same time, the balance roller 501 is abutted against the top of the track, and the device is pushed to move along the track. While the top cleaning component 2 cleans the top of the track, the two side cleaning components 3 clean the side walls of the track;

[0048] Specifically, when the balance roller 501 is abutted against the top of the track, the bottom wall of the cleaning belt 208 contacts the top of the track. The output shaft of the servo motor 209 drives the first driving pulley 2010 to rotate. The first driving 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 together with the cleaning roller 207 rotates, 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 from 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, and are carried to the top position of the D-shaped magnetic conductive outer frame 204 as the cleaning belt 208 rotates. Due to the C-shaped setting of the C-shaped permanent magnet 203, when the cleaning belt 208 carries the iron filings to the top position of the D-shaped magnetic conductive outer frame 204, the iron filings are just located between the top gaps of the C-shaped permanent magnet 203, and the iron filings are not affected by 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 driving bevel gear 2025 to rotate. The first driving bevel gear 2025 then drives the middle rotating shaft 2026 to rotate through the first driven bevel gear 2027, and further drives the second driving pulley 2028 to rotate together. The second driving 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 conveyor belt 2016 rotates under the cooperation of another conveying rod 2014 and conveying roller 2015. The rotation of the conveyor belt 2016 drives the electromagnet 2018 to rotate. During the rotation of the electromagnet 2018 with the conveyor belt 2016, the iron filings moving to the top of the D-shaped magnetic conductive outer frame 204 are adsorbed, so that during the continuous rotation and cleaning of the cleaning belt 208, the iron filings wiped last time will not be brought back to the track again, ensuring the track cleaning effect;

[0049] During the period when the conveyor belt 2016 drives the electromagnet 2018 to operate, the conductive rod 2019 and the elastic brush 2020 are synchronously driven to operate. When the electromagnet 2018 adsorbed with iron filings rotates to the top of the unloading hopper 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 electric charge inside the conductive sheet 2022 cannot be transferred to the elastic brush 2020, and then the electromagnet 2018 cannot be powered through the conductive rod 2019, resulting in the loss of the electromagnetic effect after the electromagnet 2018 is powered off. 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 hopper 2002, thereby automatically removing the iron filings on the surface of the electromagnet 2018 and preventing the iron filings adsorbed last time from being brought back again;

[0050] During the period when the staff pushes the device to move along the track, the two walking rollers 4 rotate and drive the two walking axles 3010 to rotate. The rotation of the walking axle 3010 drives the second driving bevel gear 3012 to rotate. The second driving 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 plurality of telescopic rods 304, the return springs 307 and the wire brushes 306 to rotate. Due to the action of the rotational centrifugal force, the plurality of telescopic rods 304 slide outward along the inner wall of the telescopic holes 303, driving the return springs 307 and the wire brushes 306 to move together, so that the rotation radius of the wire brushes 306 becomes larger and contacts the side wall of the track to clean the side wall of the track.

[0051] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
