Description

Technical Field

[0001] The present invention relates to the technical field of scrapers, and in particular to a cable winding protection device of an electric scraper. Background Art

[0002] A scraper is a soil transport machine that uses a bucket to scrape soil and loads the crushed soil into the bucket for transportation. It can complete the comprehensive operations of shoveling, loading, transporting, unloading, filling in layers, and compacting in parts. It is suitable for leveling sites for railways, roads, water conservancy, electricity and other projects. The scraper has the advantages of simple operation, no restrictions on terrain, independent operation, high driving speed, and high production efficiency.

[0003] Existing scrapers mainly include internal combustion scrapers and electric scrapers according to the driving mode. During the construction process, the electric scraper needs to be connected to an external power supply through cables to ensure continuous power. However, since the scraper needs to discharge the earth at the construction site during the construction process, it needs to constantly move back and forth between the construction site and the power supply, which causes the connecting cables to be dragged at will, which not only affects the construction but also poses a greater safety hazard. Existing electric scrapers are often equipped with cable winding devices, but the cables dragged out during construction often entangle themselves, causing bends on their surfaces, and the surface of the cables cannot be cleaned when they are wound, which easily causes broken soil and debris to enter the drum and damage the cables, affecting the service life of the cables.

[0004] The patent with announcement number CN218950713U discloses a cable winding device for a scraper loader, including a base, a bracket fixedly connected to the top of the base, a winding roller rotatably connected between the brackets, a motor fixedly connected to one side of the bracket, an output end of the motor fixedly connected to one end of the winding roller through a coupling, an outer surface of the winding roller fixedly connected to a limiting mechanism, and a cleaning mechanism fixedly connected to the top of the base. The advantages of this utility model are: first, one end of the cable is passed through the cleaning mechanism and wound around the winding roller, the motor is started to rotate the winding roller to rewind the cable, during the winding process, if the cable is too long, the cable will push the limit plate to move outward, and the limit plate will initially limit the cable, and after the winding is completed, the fixing bolt in the threaded hole is turned to make one end of it contact with the connecting plate, so that the connecting plate no longer moves, thereby making the limit plate no longer move, and the cable is squeezed and fixed, so that the cable will not loose easily.

[0005] Although the above patent can limit and fix the cable, when cleaning the cable, its outer surface is only cleaned by the friction between the cable and the cleaning brush when the cable moves. The dust and stains cleaned up are still attached to the cleaning brush and cannot be removed, thereby affecting the subsequent cleaning effect of the cable.

[0020] 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.

[0021] As Figure 1 - Figure 6 shown, the present invention provides a cable winding protection device for an electric LHD, which includes a fixed frame 1. On one side of the top of the fixed frame 1, a wire take-up roller 2 is provided, and a cable is wound on the wire take-up roller 2. On the other side of the top of the fixed frame 1, a limiting mechanism is provided for limiting the cable wound on the wire take-up roller 2. The limiting mechanism includes a bracket 3, a wire guide cylinder 4, a driving component 5 for driving the movement of the wire guide cylinder 4, a cleaning component 6 for cleaning the outside of the cable, and a gas guiding component 7 for supplying gas and discharging sewage into the wire guide cylinder 4. The bracket 3 is fixedly connected to the fixed frame 1, the driving component 5 is fixedly installed on the bracket 3, the wire guide cylinder 4 is fixedly arranged at the output end of the driving component 5, the gas guiding component 7 is fixedly arranged on the bracket 3 and is located below the wire guide cylinder 4, and the gas guiding component 7 is connected to the wire guide cylinder 4.

[0022] Before the present invention is used, one end of the cable is passed through the wire guide cylinder 4. When the wire take-up roller 2 rotates, it can drive the cable to perform a winding operation. Through the setting of the wire guide cylinder 4, the cable can be limited and combed before winding, avoiding self-winding and bending of the cable. Further, the driving component 5 includes a mounting plate 51, a slider 52 and a screw 53. The mounting plate 51 is horizontally fixed on the bracket 3. A chute 54 is opened in the middle of the mounting plate 51. The screw 53 is rotatably arranged in the chute 54, and one end of the screw 53 extends outside the bracket 3 and is coaxially connected to a motor. The slider 52 is sleeved on the screw 53 and is threadedly connected to the screw 53. The wire guide cylinder 4 is fixedly arranged at the bottom of the slider 52 and is located below the mounting plate 51. The motor provides power and drives the screw 53 to rotate, thereby driving the slider 52 to reciprocate inside the chute 54, so that the wire guide cylinder 4 performs a horizontal reciprocating movement, which can further comb the cable evenly and ensure the neat arrangement of the cable on the wire take-up roller 2. Through the setting of the limiting mechanism, not only the winding efficiency of the cable is improved, but also the damage to the cable during the winding process is effectively avoided, and its service life is extended.

[0023] Specifically, the cleaning component 6 includes an annular fixing plate 61, a roller 62, a scraping member 63 for scraping contaminants on the surface of the cable, a wiping member 64 for wiping the surface of the cable, and a guiding member for driving the roller 62 to rotate. The annular fixing plate 61 is fixedly arranged inside the wire guiding cylinder 4, and the annular fixing plate 61 divides the interior of the wire guiding cylinder 4 into a first cavity 66 and a second cavity 67. The roller 62 is arranged in the first cavity 66 and is rotatably connected to the middle of the annular fixing plate 61. The scraping member 63 is installed inside the roller 62, the wiping member 64 is installed in the first cavity 66 and is fixedly connected to the roller 62, and the guiding member is installed on the driving component 5 and is in transmission connection with the roller 62.

[0024] A plurality of through holes 65 are evenly formed in the inner wall of the roller 62 along the circumferential direction. On both sides of the interior of the first cavity 66, partition plates 68 are horizontally fixed. The two partition plates 68 divide the inner wall of the first cavity 66 into an air inlet cavity 69 and an air exhaust cavity 70, and the inner walls of the two partition plates 68 are in contact with the outer wall of the roller 62. The output end of the air guiding component 7 is communicated with the air inlet cavity 69, and the input end of the air guiding component 7 is communicated with the air exhaust cavity 70.

[0025] The scraping member 63 includes a plurality of silica gel scrapers 631 and a plurality of cleaning brushes 632. The plurality of silica gel scrapers 631 and the plurality of cleaning brushes 632 are alternately fixed on the inner wall of the roller 62 along the circumferential direction. At both ends of the inner wall of the roller 62, annular sealing plates 633 are fixedly connected, and the two annular sealing plates 633 are respectively located on both sides of the silica gel scraper 631 and the cleaning brush 632.

[0026] When the driving component 5 drives the wire guiding cylinder 4 to move, through the cooperation of the guiding member, the roller 62 can be driven to rotate inside the wire guiding cylinder 4. The guiding member includes a toothed plate 651. The toothed plate 651 is fixedly arranged on the side wall of the driving component 5. One end of the roller 62 extends to the outside of the wire guiding cylinder 4 and is fixedly connected with a guiding gear 652. The guiding gear 652 meshes with the toothed plate 651.

[0027] Since the guiding gear 652 meshes with the toothed plate 651, when the wire guiding cylinder 4 moves, the roller 62 inside it moves synchronously. At this time, the guiding gear 652 rotates under the meshing action with the toothed plate 651, so that the roller 62 rotates inside the wire guiding cylinder 4. At this time, the scraping member 63 inside the roller 62 closely adheres to the surface of the cable, so that the silica gel scraper 631 and the cleaning brush 632 are in contact with the outer surface of the cable. As the roller 62 rotates, the silica gel scraper 631 can scrape off the impurities on the surface of the cable, and the cleaning brush 632 brushes off the dust adhering to the surface of the cable together. Since the silica gel scraper 631 and the cleaning brush 632 are in soft contact with the cable, the lengths of the silica gel scraper 631 and the cleaning brush 632 can be greater than the radius of the roller 62 to adapt to cables of different diameters and ensure the cleaning effect.

[0028] Further, the silicone scraper 631 and the cleaning brush 632 can be arranged spirally or horizontally along the inner wall of the drum 62. When the cable is being wound, it moves inside the wire guide tube 4. At this time, the silicone scraper 631 and the cleaning brush 632 are arranged spirally or horizontally, which can increase the contact area and friction force with the cable surface, thus greatly improving the cleaning effect. In addition, the spirally or horizontally arranged silicone scraper 631 and cleaning brush 632 can also gradually clean the cable surface as the cable moves, avoiding the problems of incomplete cleaning or damage to the cable surface that may be caused by one-time cleaning. This not only improves the cleaning efficiency but also ensures the safety of the cable during the winding process and extends the service life of the cable. By setting up the cleaning component 6, it is possible to clean the impurities and dust on the cable surface during the cable winding process, preventing the impurities and dust from winding around the take-up roller 2 with the cable, causing damage to the cable surface and affecting the subsequent winding of the cable.

[0029] After the silicone scraper 631 and the cleaning brush 632 have cleaned the impurities and dust on the cable, the dust will fall into the inside of the drum 62. The scraped impurities and dust can enter the air inlet cavity 69 through the through hole 65. At this time, the air guiding component 7 is started to discharge the dust in the air inlet cavity 69 through the exhaust cavity 70, preventing the dust from accumulating inside the drum 62 and affecting subsequent use.

[0030] The air guiding component 7 includes a fixed box 71, a filter cylinder 72, an air pump 73, and two bellows 74. The fixed box 71 is fixedly arranged on the bracket 3. The filter cylinder 72 is arranged inside the fixed box 71. The air pump 73 is slidably arranged on the top of the fixed box 71, and a fixed pipe 75 is connected between the top of the air pump 73 and the bottom of the wire guide tube 4. The fixed pipe 75 is communicated with the exhaust cavity 70. The two bellows 74 are respectively fixed on both sides of the outer wall of the air pump 73, and the other ends of the two bellows 74 are both fixedly connected to the bracket 3. The input end of the air pump 73 is communicated with the fixed pipe 75, the output end of the air pump 73 is communicated with the inside of one of the bellows 74, and the other end of this bellows 74 is fixedly connected with a U-shaped pipe 76. The U-shaped pipe 76 sequentially penetrates through the fixed box 71 and the filter cylinder 72 and extends into the inside of the filter cylinder 72. The two ends of the other bellows 74 are respectively connected with an air delivery pipe 77 and an air guide pipe 78. The air delivery pipe 77 is communicated with the air inlet cavity 69, and the air guide pipe 78 is communicated with the inside of the fixed box 71.

[0031] After the air pump 73 is started, the gas in the exhaust cavity 70 is pumped out through the fixed pipe 75. Since the intake cavity 69 and the exhaust cavity 70 are separated by two partition plates 68, and the inner walls of the two partition plates 68 are in contact with the outer wall of the drum 62, during the process of the air pump 73 pumping air, the dust and impurities entering the interior of the exhaust cavity 70 pass through the fixed pipe 75, the corrugated pipe 74, and the U-shaped pipe 76 in sequence and are then transported to the filter cartridge 72 for filtration. After being filtered by the filter cartridge 72, the impurities and dust in the gas are intercepted in the filter cartridge 72, while the clean gas is transported to another corrugated pipe 74 through the air guide pipe 78 and then transported to the interior of the intake cavity 69 through the air delivery pipe 77. The gas entering the interior of the intake cavity 69 blows towards the surface of the cable through the through holes 65 to blow off the dust and impurities adhering to the surface of the cable, achieving the purpose of assisting in cleaning the surface of the cable. By providing the air guide assembly 7, the auxiliary cleaning of the surface of the cable is realized, as well as the effective collection and treatment of the impurities and dust generated during the cleaning process of the cable surface, improving the service life of the cable.

[0032] Among them, by providing two partition plates 68, the intake cavity 69 and the exhaust cavity 70 can be separated. At the same time, the inner wall of the partition plate 68 is in contact with the outer wall of the drum 62, which can prevent impurities and dust from entering the interior of the intake cavity 69 through the gap between the two partition plates 68 and the drum 62, ensuring the purity of the gas in the intake cavity 69 and improving the auxiliary effect of the air guide assembly 7 on cleaning the surface of the cable.

[0033] By providing two annular sealing plates 633, the interior of the drum 62 can be enclosed. If impurities and dust enter the second cavity 67, it will affect the cleaning effect of the cable. At the same time, the two annular sealing plates 633 can also prevent impurities and dust from rolling out from both ends of the drum 62, further improving the cleaning effect of the cleaning assembly 6.

[0034] The wiping member 64 includes an installation barrel frame 641, a sponge ring 642, and a screw sleeve 643. The installation barrel frame 641 is fixed in the second cavity 67, and one end of the installation barrel frame 641 is fixedly connected to the end of the drum 62. The other end of the installation barrel frame 641 extends outside the wire drum 4. The sponge ring 642 is fixedly arranged inside the installation barrel frame 641. The screw sleeve 643 is threadedly connected to one end of the inner wall of the installation barrel frame 641, and the screw sleeve 643, the sponge ring 642, and the installation barrel frame 641 are coaxial.

[0035] During the rotation of the drum 62, the sponge ring 642 can closely adhere to the surface of the cable for wiping to remove the fine impurities and dust remaining on the outer surface of the cable, further improving the cleanliness of the cable. Since the sponge ring 642 has good elasticity and water absorption, during the wiping process, it can adapt to cables with different diameters to ensure the wiping effect; and during the wiping process, it can also wipe off the moisture on the surface of the cable, not only improving the usability of the cable, but also extending the service life of the cable.

[0036] After the sponge ring 642 has been used for a long time, there will be more impurities and dust remaining on its surface. At this time, by rotating the screw sleeve 643, the screw sleeve 643 can be removed from the mounting cylinder frame 641. At this time, the sponge ring 642 can be taken off from the mounting cylinder frame 641 for cleaning or replacement, which not only facilitates the user to maintain the sponge ring 642, but also ensures that the cable winding protection device can continue to work effectively.

[0037] To further improve the wiping effect, tiny convex structures can be provided on the inner side of the sponge ring 642. These convex structures can increase the friction with the surface of the cable during the wiping process, thus more effectively removing the stubborn stains on the surface of the cable. At the same time, the convex structures will not cause any damage to the surface of the cable, ensuring the integrity and safety of the cable.

[0038] The scope of protection claimed is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and scope of protection of this application, and such modifications or equivalent replacements should also be regarded as falling within the scope of protection of this application.
