Description

Technical Field

[0001] This invention relates to the field of rail scrap cleaning technology, and in particular to a rail grinding scrap cleaning device and its usage method. Background Technology

[0002] With the rapid development of high-speed railways, rail grinding has become a mandatory course for every pair of rails before they are put into service, in order to increase railway speed. Traditionally, two methods are used to clean up iron filings after rail grinding: one is to use a backpack blower to collect the iron filings in units of a certain length, then use a broom or dustpan to collect them into woven bags and remove them from the track; the other is to use a large vacuum cleaner and vacuum truck to collect the iron filings from the rails. However, both of these iron filings removal methods are performed after the grinding machine has finished grinding the rails, resulting in low efficiency in rail preparation. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a device for cleaning iron filings from rail grinding and a method for using the same. The technical solution of the present invention is as follows: In a first aspect, the present invention provides a device for cleaning iron filings from rail grinding, comprising a collection assembly connected to a grinding machine via multiple retaining rings; a cleaning brush head connected to both sides of the collection assembly and in contact with the side wall of the rail for cleaning iron filings; an absorbent cloth laid in the collection assembly for absorbing iron filings; and a spraying component connected to the water tank of the grinding machine and positioned above the collection assembly for spraying the absorbent cloth.

[0004] The present invention provides a device for cleaning iron filings from steel rail grinding. The collection component includes a drawer tray with inclined sides and a raised section in the middle for obstacle avoidance. The drawer tray has multiple first and second connecting holes. A retaining ring is installed in the first connecting hole and connected to the winding wheel of the grinding machine. Cleaning brush heads are connected to both sides of the drawer tray. Two baffles are vertically arranged at the front and rear ends of the drawer tray, respectively, with a sealing strip between the baffles and the drawer tray. A pin is inserted into both sides of the two baffles and fixedly connected to the second connecting hole of the drawer tray. The pin is used to connect a reinforcing screw, thereby connecting to the body of the grinding machine.

[0005] The present invention provides a device for cleaning iron filings from steel rail grinding, wherein the absorbent cloth includes a hydrophobic layer laid on the upper surface of the drawer tray; a water storage layer located above the hydrophobic layer; and a colloidal layer located above the water storage layer.

[0006] The rail grinding iron filings cleaning device provided by the present invention also includes ball bearings. The upper surface of the drawer tray is provided with multiple slots for holding the ball bearings, and the top of the ball bearings is covered with an absorbent cloth.

[0007] The rail grinding iron filings cleaning device provided by the present invention further includes multiple support bars, which are arranged in parallel on the adsorption cloth; and two adhesive strips, which are respectively connected to the side of the adsorption cloth, and are arranged in parallel with the support bars.

[0008] The rail grinding iron filings cleaning device provided by the present invention further includes a barb connected to the rear end of the drawer tray; and a collection bag hung on the barb.

[0009] Secondly, the present invention also provides a method of using the rail grinding metal shavings cleaning device, the method of using the device designed based on the above-mentioned rail grinding metal shavings cleaning device, comprising: S1: Before the grinding machine is ready to operate, install the rail grinding shavings cleaning device on the grinding machine; S2: Drive the spray unit to spray the absorbent cloth laid on the drawer tray, so that the absorbent cloth is wetted to absorb iron filings and suppress dust, and make the cleaning brush heads on both sides of the drawer tray contact the side wall of the rail. S3: When the grinder travels to the work area, it collects the iron filings produced during grinding onto a damp absorbent cloth. S4: After the grinding machine finishes its operation, adjust the tilt of the drawer tray so that the absorbent cloth carrying the iron filings slides down into the collection bag.

[0010] The method of using the rail grinding and scrap cleaning device provided by the present invention includes, in step S2: The driving spray unit sprays water onto the absorbent cloth laid on the drawer tray. The colloidal layer in the absorbent cloth becomes wet and expands to absorb liquid, thus adsorbing iron filings.

[0011] The method of using the rail grinding and scrap cleaning device provided by the present invention, in step S3, further includes: During the operation of the grinding machine, the spray nozzles continuously spray liquid. The water storage layer in the absorbent cloth absorbs the liquid continuously sprayed by the spray nozzles, while the hydrophobic layer of the absorbent cloth isolates the drawer tray from the liquid sprayed by the spray nozzles.

[0012] The method of using the rail grinding and scrap cleaning device provided by the present invention includes, in step S4: Adjust the reel of the sander so that the front end of the drawer tray is higher than the rear end, thus tilting the drawer tray. Remove the back panel of the drawer tray and hang the collection bag on the hook at the back of the drawer tray; The absorbent cloth slides down towards the rear of the drawer tray under the action of the inclined drawer tray and the ball bearings, and then slides into the collection bag, completing the collection of the absorbent cloth.

[0013] All of the above-mentioned optional technical solutions can be combined arbitrarily, and the present invention will not provide a detailed description of the structure after each combination.

[0014] By means of the above solution, the beneficial effects of the present invention are as follows: By configuring a collection component, cleaning brush head, absorbent cloth, and spraying device, the collection component is connected to the grinding machine. The cleaning brush head is connected to both sides of the collection component and contacts the side wall of the rail. The absorbent cloth is laid on the collection component, and the spraying device is connected to the water supply of the grinding machine and positioned above the collection component. Driving the spraying device sprays water onto the absorbent cloth, wetting it. When the grinding machine grinds the rail, the cleaning brush head abuts against the side wall of the rail, sweeping the grinding chips onto the absorbent cloth, thus achieving the collection of iron chips during the grinding process. Furthermore, the spraying operation allows fine iron particles in the air to fall quickly, preventing dust. This application achieves the cleaning of iron chips during the grinding process, enabling cleaning during grinding without the need for secondary cleaning by operators, reducing workload and improving the efficiency of rail preparation.

[0015] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0018] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0019] like Figures 1 to 13 As shown, the present invention provides a cleaning device for iron filings from rail grinding, including a collection component 1, which is connected to a grinding machine via multiple retaining rings 5; a cleaning brush head 2, which is connected to both sides of the collection component 1 and contacts the side wall of the rail 20 for cleaning iron filings; an absorbent cloth 3, which is laid in the collection component 1 for absorbing iron filings; and a spraying component 4, which is connected to the water tank of the grinding machine and is positioned above the collection component 1 for spraying the absorbent cloth 3.

[0020] Specifically, in this embodiment, the cleaning brush head 2 is a 90mm stiff long brush.

[0021] It should be noted that the liquid sprayed by the spraying component 4 in this embodiment is water.

[0022] By setting up a collection component 1, a cleaning brush head 2, an absorbent cloth 3, and a spraying component 4, the spraying component 4 is driven to spray the absorbent cloth 3, making the absorbent cloth 3 wet. When the grinding machine grinds the rail 20, the cleaning brush head 2 abuts against the side wall of the rail 20, which can sweep the grinding iron filings onto the absorbent cloth 3, thereby realizing the collection of iron filings during the grinding process. In addition, the spraying operation of the spraying component 4 can make the fine iron particles in the air fall quickly, avoiding dust. This application realizes the cleaning of iron filings during the grinding process of the grinding machine, achieving cleaning at any time during grinding, eliminating the need for secondary cleaning of the rail 20 by operators, reducing workload, and improving the work efficiency of preparing the rail 20.

[0023] The present invention provides a cleaning device for steel rail grinding shavings. The collecting component 1 includes a drawer tray 110, the two sides of which are set with inclined structures, and the middle of the drawer tray 110 is set with a protruding structure for obstacle avoidance. The drawer tray 110 has multiple first connecting holes 111 and second connecting holes 112. A retaining ring 5 is installed in the first connecting hole 111 and connected to the winding wheel 6 of the grinding machine. Cleaning brush heads 2 are connected to the two sides of the drawer tray 110. Two baffles 113 are respectively vertically set at the front end and rear end of the drawer tray 110. A sealing strip 114 is provided between the baffles 113 and the drawer tray 110. A pin 115 is inserted into the two sides of the two baffles 113 and fixedly connected to the second connecting hole 112 of the drawer tray 110. The pin 115 is used to connect the reinforcing screw 10 and then connect to the body of the grinding machine.

[0024] Specifically, in this embodiment, the drawer tray 110 is configured with a W-shaped structure and is made of alloy plate; in this embodiment, the number of the first connecting hole 111 and the second connecting hole 112 are both set to four, respectively located at the four corners of the drawer tray 110; in this embodiment, the first connecting hole 111 is a threaded hole, and the retaining ring 5 is connected to the first connecting hole 111 by a threaded connection; in this embodiment, the number of the pins 115 is set to four, and the bottom of the pins 115 is connected to the second connecting hole 112 by welding; in this embodiment, the absorbent cloth 3 is also provided with the first connecting hole 111 at the four corners, and the absorbent cloth 3 is fixed to the drawer tray 110 by the retaining ring 5.

[0025] In a specific implementation, the bottom of the grinder is provided with a winding wheel 6 and an anti-climb device 7. A guide cable 8 is wound on the winding wheel 6. The winding wheel 6 can retract and extend the guide cable 8, thereby adjusting the distance between the drawer tray 110 and the ground. The four corners of the drawer tray 110 are connected to the guide cable 8 through retaining rings 5. The anti-climb device 7 is installed on the guide cable 8 to prevent the guide cable 8 from reversing. The bottom of the pin 115 is fixedly connected to the drawer tray 110, the side of the baffle 113 is inserted into the pin 115, one end of the reinforcing screw 10 is threaded to the top of the pin 115, and the other end of the reinforcing screw 10 is connected to the ear 9 of the grinder body. The reinforcing screw 10 is fixed by the nut 11. In this embodiment, the reinforcing screw 10 includes a long reinforcing screw and a short reinforcing screw. When the grinder is traveling and has not reached the work area, in order to avoid the drawer tray 110 being too short from the ground and thus colliding with the ground equipment, a short reinforcing screw can be used to increase the height of the drawer tray 110 from the ground. When the grinder is traveling and has reached the work area, the cleaning brush heads 2 on both sides of the drawer tray 110 should contact the rail web of the rail 20. Therefore, the short reinforcing screw can be removed, and the winding wheel 6 can be adjusted to shorten the height of the drawer tray 110 from the ground. Then, a long reinforcing screw can be used to fix the drawer tray 110 and prevent the drawer tray 110 from shaking.

[0026] Furthermore, the cleaning brush head 2 is connected to the side of the drawer tray 110 via a snap-fit ​​connector 12. After the snap-fit ​​connector 12 is connected to the side of the drawer tray 110, it is further fixed with bolts, which can prevent the snap-fit ​​connector 12 from detaching from the drawer tray 110, thus achieving a stable connection of the cleaning brush head 2. It also enables the quick installation and removal of the cleaning brush head 2, making it convenient to replace the cleaning brush head 2.

[0027] By setting the drawer tray 110 to a W-shaped structure, collisions with equipment such as the transponder 19 installed on the ground in the area where the rail 20 is located can be avoided; by setting the baffle 113, a relatively enclosed space can be formed in the drawer tray 110, preventing the collected iron filings from flying around; by setting the pin 115 on the drawer tray 110, the baffle 113 can be detachably connected, and the drawer tray 110 can be prevented from obstructing the movement of the grinding machine. At the same time, a stable connection between the drawer tray 110 and the grinding machine body can be achieved, preventing the drawer tray 110 from shaking; by setting the sealing strip 114 at the bottom of the baffle 113, the mixture of iron filings and water can be prevented from flowing out during operation, improving the collection effect of the drawer tray 110.

[0028] The rail grinding iron filings cleaning device provided by the present invention further includes an absorbent cloth 3 comprising a hydrophobic layer 31, which is laid on the upper surface of the drawer tray 110; a water storage layer 32, which is located above the hydrophobic layer 31; and a colloidal layer 33, which is located above the water storage layer 32.

[0029] Specifically, in this embodiment, the colloidal layer 33 is composed of a material that can absorb water and form a colloid, and its surface is covered with an algae coating. When the liquid sprayed by the sprayer 4 wets the absorbent cloth 3, the coating dissolves, and the colloidal material absorbs the liquid and expands, which facilitates the adsorption of iron filings. The water storage layer 32 can store the liquid that the colloid cannot adsorb in time, preventing the liquid from flowing out and contaminating the rail 20. The hydrophobic layer 31 is composed of a smooth plastic cloth, which can separate the liquid sprayed by the sprayer 4 from the drawer tray 110. In this embodiment, the cleaning brush head 2 can contact the middle part of the side wall of the rail 20, that is, the rail web of the rail 20.

[0030] Furthermore, in this embodiment, the colloidal layer 33 can be coated with cross-linked sodium polyacrylate and sodium alginate, the water storage layer 32 can be made of hydrophilic polyurethane foam, and the hydrophobic layer 31 can be made of polyethylene film.

[0031] The rail grinding iron filings cleaning device provided by the present invention also includes a ball bearing 13. The upper surface of the drawer tray 110 is provided with a plurality of slots 14 for holding the ball bearing 13, and the top of the ball bearing 13 is covered with an absorbent cloth 3.

[0032] In a specific implementation, when the grinding machine finishes its operation, the iron filings cleaning operation is completed simultaneously. The operator removes the retaining ring 5 to remove the absorbent cloth 3, and adjusts the winding wheel 6 to the degree of winding and unwinding of the guide cable 8 so that the front end of the drawer tray 110 is higher than the rear end, so that the drawer tray 110 is tilted and the absorbent cloth 3 can slide down from the rear end. Since the hydrophobic layer 31 of the absorbent cloth 3 is composed of a smooth plastic cloth, it can slide in conjunction with the ball bearing 13, making it convenient for the absorbent cloth 3 to slide down.

[0033] By setting multiple ball bearings 13 on the drawer tray 110, it is easier for the absorbent cloth 3 to slide down, thus speeding up the collection process of the absorbent cloth 3.

[0034] The rail grinding iron filings cleaning device provided by the present invention also includes multiple support bars 15, which are arranged in parallel on the adsorption cloth 3; and two adhesive strips 16, which are respectively connected to the side of the adsorption cloth 3, and are arranged in parallel with the support bars 15.

[0035] By setting multiple support strips 15 in parallel on the absorbent cloth 3 and connecting adhesive strips 16 to both sides of the absorbent cloth 3, the structural strength of the absorbent cloth 3 can be increased, and the absorbent cloth 3 can be rolled up during the sliding process, making it easy to store the absorbent cloth 3.

[0036] The rail grinding iron filings cleaning device provided by the present invention further includes a barb 17 connected to the rear end of the drawer tray 110; and a collection bag 18 hung on the barb 17.

[0037] Specifically, in this embodiment, the number of barbs 17 is set to two, and the collection bag 18 is hung on the two barbs 17.

[0038] In a specific implementation, to prevent the collection bag 18 from falling, the barb 17 is installed in the opposite direction. This prevents the collection bag 18 from accidentally falling when storing the absorbent cloth 3. Before storing the absorbent cloth 3, the collection bag 18 is in a wrapped state, which helps to open the opening of the collection bag 18 and facilitates the fall of the absorbent cloth 3. As the absorbent cloth 3 slides into the collection bag 18, the collection bag 18 gradually unfolds.

[0039] By setting up the barb 17 and the collection bag 18, it is easy to store the absorbent cloth 3, thereby collecting iron filings.

[0040] The present invention also provides a method of using the rail grinding metal shavings cleaning device, the method of using the device based on the above-mentioned rail grinding metal shavings cleaning device comprising: S1: Before the grinding machine is ready to operate, install the cleaning device for grinding iron filings on the rail 20 on the grinding machine; S2: Drive the spraying component 4 to spray the absorbent cloth 3 laid on the drawer tray 110, so that the absorbent cloth 3 is wetted to absorb iron filings and suppress dust, and make the cleaning brush heads 2 on both sides of the drawer tray 110 contact the side wall of the rail 20. S3: When the grinder travels to the working area, the iron filings generated during grinding are collected on the damp absorbent cloth 3. S4: After the grinding machine finishes its operation, adjust the tilt of the drawer tray 110 so that the absorbent cloth 3 carrying the iron filings slides into the collection bag 18.

[0041] The method of using the rail 20 grinding and scrap cleaning device provided by the present invention includes, in step S2: The driving spray component 4 sprays the absorbent cloth 3 laid on the drawer tray 110. The colloidal layer 33 in the absorbent cloth 3 is moistened and can absorb liquid expansion, thus adsorbing iron filings.

[0042] The method of using the rail 20 grinding and scrap cleaning device provided by the present invention, in step S3, further includes: During the operation of the grinding machine, the spraying component 4 continuously sprays liquid, the water storage layer 32 in the absorbent cloth 3 absorbs the liquid continuously sprayed by the spraying component 4, and the hydrophobic layer 31 of the absorbent cloth 3 isolates the drawer tray 110 from the liquid sprayed by the spraying component 4.

[0043] The method of using the rail 20 grinding and scrap cleaning device provided by the present invention includes, in step S4: Adjust the winding wheel 6 of the sander so that the front end of the drawer tray 110 is higher than the rear end, thereby tilting the drawer tray 110. Remove the baffle 113 at the rear end of the drawer tray 110 and hang the collection bag 18 on the hook 17 at the rear end of the drawer tray 110. The absorbent cloth 3 slides down towards the rear end of the drawer tray 110 under the action of the inclined drawer tray 110 and the ball bearing 13, and then slides into the collection bag 18, thus completing the collection of the absorbent cloth 3.

[0044] A more specific implementation is as follows: Before the grinding machine is ready to operate, the front and rear ends of the drawer tray 110 are connected to baffles 113, and each baffle 113 has pins 115 inserted and connected on both sides, and the bottom of the pins 115 is fixedly connected in the second connection hole 112. The absorbent cloth 3 is laid on the upper surface of the drawer tray 110, and the retaining ring 5 is connected to the first connection hole 111 between the drawer tray 110 and the absorbent cloth 3. The retaining ring 5 is connected to the guide cable 8 of the grinder, and the winding wheel 6 of the grinder is adjusted to adjust the distance of the drawer tray 110 from the ground; When the grinder is traveling and has not reached the work area, the top of each pin 115 is connected to one end of a short reinforcing screw, and the other end of the short reinforcing screw is connected to the body of the grinder to increase the ground clearance of the drawer tray 110 and ensure the normal travel of the grinder. When the grinder travels and arrives at the work area, remove the short reinforcing screw, slowly lower the drawer tray 110 so that the drawer tray 110 is flush with the bottom of the rail 20, and then adjust the winding wheel 6 to raise the height of the drawer tray 110 so that the cleaning brush heads 2 on both sides of the drawer tray 110 contact the side wall of the rail 20 without squeezing. The top of each pin 115 is connected to one end of a long reinforcing screw, and the other end of the long reinforcing screw is connected to the body of the grinder to shorten the distance of the drawer tray 110 from the ground. Drive the spraying component 4 to spray the adsorption cloth 3 in a mist, so that the colloidal layer 33 in the adsorption cloth 3 is moistened to produce colloidal material, so as to better adsorb iron filings. The movement of the grinder causes the drawer tray 110 to move together, and the cleaning brush head 2 sweeps the iron filings onto the damp absorbent cloth 3. After the grinding machine operation is completed, remove the long reinforcing screw and then remove the retaining ring 5 so that the absorbent cloth 3 can move freely; Connect the retaining ring 5 to the first connecting hole 111 of the drawer tray 110, adjust the winding wheel 6 to lower the drawer tray 110, and clean the dust from the polishing machine. Remove the baffle 113 located at the rear end of the drawer tray 110 and hang the collection bag 18 on the hook 17 at the rear end of the drawer tray 110. Adjust the retractor 6 so that the front end of the drawer tray 110 is higher than the rear end, thereby tilting the drawer tray 110. The absorbent cloth 3 slides down toward the rear end of the drawer tray 110, while multiple balls 13 set on the upper surface of the drawer tray 110 roll between the drawer tray 110 and the hydrophobic layer 31 with the cloth attached, thereby pushing the absorbent cloth 3 down. The absorbent cloth 3 slides down into the collection bag 18, completing the collection of the absorbent cloth 3, thereby collecting the iron filings and completing the cleaning of the iron filings on the rail 20. After installing the baffle 113 at the rear end of the drawer tray 110, adjust the retractor 6 so that the drawer tray 110 is at a certain height. The top of each pin 115 is connected to one end of a short reinforcing screw, and the other end of the short reinforcing screw is connected to the body of the grinder to increase the distance of the drawer tray 110 from the ground, making it easier for the grinder to move and park.

[0045] It should be noted that the drawer tray 110, guide rope 8, long reinforcing screw and short reinforcing screw in this application all need to be coated with protective paint to have high corrosion resistance.

[0046] In summary, this application can be carried out simultaneously with the grinding operation of the grinding machine, allowing for grinding and cleaning at any time; the operation is not affected by rainy weather, which can greatly reduce the number of personnel assisting in the iron filings cleaning operation and reduce the workload; the iron filings swept up during the operation are collected on the absorbent cloth 3, which facilitates the recycling and reuse of iron filings, and there is basically no fuel consumption during the operation, which is conducive to the advancement of sustainable development theory.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
