Description

Technical Field

[0001] The utility model relates to the technical field of road rollers, in particular to a protection structure for fixing the positions of double steel wheels of a road roller. Background Technique

[0002] A road roller, also known as a soil compactor, is a road construction equipment. Road rollers are widely used in the filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, and airport runways. A double steel wheel road roller is a road roller equipment with steel wheels installed at both the front and the rear. When the existing double steel wheel road rollers are in use, a scraper for cleaning the surface of the steel wheels is usually installed at the front and rear steel wheels of the road roller. However, the position of this scraper is generally fixed. At the same time, a water spraying mechanism for spraying water is generally installed at the steel wheels of the existing double steel wheel road rollers. After long-term use or long-term storage, a large amount of rust will appear on the steel wheels. If the rust is not removed, rust will appear on the ground at the beginning of the work, affecting the compaction effect on the ground. Content of the Utility Model

Specific implementation mode

[0018] 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.

[0019] The present invention provides a technical solution: As Figures 1 to 4 shown, in this embodiment, a protection structure for fixing the positions of the double drums of a roller includes a double-drum roller body 1. Steel drums 2 are installed in front of and behind the double-drum roller body 1. Fixed rods 3 are fixedly installed on both sides in front of and behind the double-drum roller body 1. A rotary drum 4 is rotatably installed on the outside of the fixed rod 3, and the rotation position of the rotary drum 4 can be fixed. A fixed plate 5 is fixedly installed on the outside of the rotary drum 4. A scraper 6 is installed in the middle between the two fixed plates 5. The bottom end of the scraper 6 is triangularly arranged, and the bottom end of the scraper 6 is used to contact the surface of the steel drum 2 to remove the adhesives on the surface of the steel drum 2. A grinding roller 7 is installed between the ends of the two fixed plates 5 away from the rotary drum 4. The grinding roller 7 is used to grind and clean the rust on the surface of the steel drum 2.

[0020] As Figures 1 to 4 shown, the top end of the scraper 6 is fixedly installed with a mounting rod 8. The mounting rod 8 is rotatably installed between the two fixed plates 5. Torsion springs 9 are symmetrically sleeved on the outside of both ends of the mounting rod 8. One end of the torsion spring 9 is fixedly connected to the fixed plate 5, and the other end of the torsion spring 9 is fixedly connected to the end of the mounting rod 8.

[0021] When adjusting the rotation angle of the fixed plate 5, under the torsion of the torsion spring 9 on the mounting rod 8, it is ensured that the bottom end of the scraper 6 always contacts the surface of the steel drum 2.

[0022] As Figures 1 to 4As shown in the figure, an installation plate 10 is fixedly installed between the ends of the two fixing plates 5 away from the rotating cylinder 4. Positioning holes 11 are symmetrically formed in the middle of the installation plate 10. A positioning rod 12 is slidably installed inside the positioning holes 11. A bottom fixing plate 12 is fixedly installed at the bottom of the two positioning rods 12. A grinding roller 7 is fixedly installed in the middle of the positioning rod 12. An extrusion spring 13 is sleeved on the outer side of the top of the positioning rod 12. One end of the extrusion spring 13 is fixedly connected to the installation plate 10, and the other end of the extrusion spring 13 is fixedly connected to the top of the positioning rod 12.

[0023] When adjusting the angle of the fixing plate 5, the positioning rod 12 will slide inside the positioning hole 11. Under the pulling of the extrusion spring 13 on the positioning rod 12, while ensuring that the grinding roller 7 is in contact with the steel wheel 2, the extrusion force between the grinding roller 7 and the steel wheel 2 is increased, which is used to improve the rust grinding effect on the surface of the steel wheel 2.

[0024] As Figures 1 to 4 shown, a sliding cylinder 14 is slidably installed on the outer side of the rotating cylinder 4. A plug rod 15 is fixedly installed at one end of the sliding cylinder 14. Jack holes 16 are annularly and arrayedly formed at the positions corresponding to the rotation trajectories of the plug rod 15 in front of and behind the double-steel-wheel roller body 1. The jack holes 16 are slidably connected to the plug rod 15.

[0025] Insert the plug rod 15 into the jack hole 16 to control the rotation angle of the rotating cylinder 4 and ensure that the positions of the scraper 6 and the grinding roller 7 remain unchanged.

[0026] As Figures 1 to 4 shown, a pulling spring 17 is installed inside the rotating cylinder 4. One end of the pulling spring 17 is fixedly connected to the inner wall of the rotating cylinder 4, and the other end of the pulling spring 17 is fixedly connected to the inner wall of the sliding cylinder 14.

[0027] When adjusting the angle of the fixing plate 5, under the extrusion of the grinding roller 7 and the steel wheel 2, the positioning rod 12 will slide inside the positioning hole 11 to adjust the position of the grinding roller 7 and ensure that the grinding roller 7 is always in contact and extrusion with the steel wheel 2.

[0028] As Figures 1 to 4 shown, sliding blocks 18 are symmetrically and fixedly installed on the inner wall of the sliding cylinder 14. A sliding groove 19 is formed at the position corresponding to the sliding block 18 in the middle of the rotating cylinder 4. The sliding groove 19 is slidably connected to the sliding block 18.

[0029] By sliding the sliding block 18 inside the sliding groove 19, the rotation of the rotating cylinder 4 can be controlled while rotating the sliding cylinder 14 to ensure the synchronization of the rotation of the rotating cylinder 4 and the sliding cylinder 14.

[0030] The present invention provides a protection structure for fixing the positions of the double steel wheels of a road roller, and the specific working principle is as follows:

[0031] When the device is in use, by pulling the sliding cylinder 14, the insertion rod 15 slides out of the insertion hole 16. At this time, the pulling spring 17 is in a stretched state. Rotating the sliding cylinder 14 will drive the rotating cylinder 4 to rotate, and insert the insertion rod 15 into another insertion hole 16 to fix the position of the rotating cylinder 4. At this time, the bottom end of the scraper 6 will contact the surface of the steel wheel 2. When the double steel wheel roller body 1 moves, the steel wheel 2 will rotate, and the scraper 6 can remove the adhesives on the surface of the steel wheel 2. At the same time, the grinding roller 7 will also contact the surface of the steel wheel 2 to grind and clean the rust on the surface of the steel wheel 2. When it is necessary to adjust the contact force between the grinding roller 7 and the surface of the steel wheel 2 to improve the rust grinding effect on the surface of the steel wheel 2, insert the insertion rod 15 into an insertion hole 16 at a higher position. At this time, the scraper 6 will rotate under the extrusion of the surface of the steel wheel 2, but the bottom end of the scraper 6 will also contact the surface of the steel wheel 2, which can improve the removal effect of the adhesives on the surface of the steel wheel 2. At the same time, under the extrusion of the grinding roller 7 and the steel wheel 2, the positioning rod 12 will slide inside the positioning hole 11, and the extrusion spring 13 is in a stretched state. Under the pulling of the extrusion spring 13 on the positioning rod 12, while ensuring the contact between the grinding roller 7 and the steel wheel 2, the extrusion force between the grinding roller 7 and the steel wheel 2 is increased to improve the rust grinding effect on the surface of the steel wheel 2.

[0032] 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.
