Description

Technical Field

[0001] The utility model relates to the technical field of road rollers, in particular to a double smooth-wheel road roller. Background Technique

[0002] With the rapid development of modern infrastructure construction, efficient and precise construction equipment has become increasingly important. A double smooth-wheel road roller is a construction equipment that uses double smooth wheels for compaction operations. Its working principle mainly depends on two smooth and heavy wheels, which compact the ground through the pressure generated by rolling. This compaction method can effectively improve the density of the foundation and enhance the bearing capacity of the road surface. Double smooth-wheel road rollers are widely used in many fields, such as road construction, airport runways, bridges, parking lots, etc. During the process of the double smooth-wheel road roller flattening the ground, the compaction wheels of the double smooth-wheel road roller will roll over the soil layer, and the soil will easily adhere to the surface of the compaction wheels, resulting in an uneven soil layer on the ground after compaction, affecting the compaction quality. Moreover, it is inconvenient to clean the soil adhered to the compaction wheels, resulting in a reduction in work efficiency.

[0003] In summary, the utility model designs a double smooth-wheel road roller to solve the existing problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a double smooth-wheel road roller to solve the problems raised in the above background technique.

An inlet is opened at one end of the top of the water tank. Connecting pipes are symmetrically installed on the relatively wide outer sides of the water tank. A water distribution pipe is installed at one end of the connecting pipe. A number of spray heads are installed on the outer side of the water distribution pipe away from the connecting pipe.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] For the embodiments, please refer to Figures 1-5 , this utility model provides a technical solution:

[0026] A double-drum roller includes a roller body 1. At both ends of the bottom of the roller body 1, pressing wheels 2 are symmetrically installed. At the bottom of the roller body 1 and between the two pressing wheels 2, a support plate 3 is installed. At the bottom of the support plate 3, a water tank 4 is installed. At one end of the top of the water tank 4, a water inlet 5 is opened. On the relatively wide outer sides of the water tank 4, connecting pipes 6 are symmetrically installed. At one end of the connecting pipe 6, a water distribution pipe 7 is installed. On the outer side of the water distribution pipe 7 away from the connecting pipe 6, a plurality of spray nozzles 8 are installed;

[0027] At the bottom of the water tank 4, an equipment box 9 is installed. Inside the equipment box 9, a cavity 901 is opened. At the inner bottom of the cavity 901, a servo motor 10 is installed. On the output shaft of the servo motor 10, a first bevel gear 11 is installed. On the relatively wide inner side walls of the cavity 901, threaded rods 12 are symmetrically installed. At one end of the threaded rod 12, a second bevel gear 13 is installed. At the end of the threaded rod 12 away from the second bevel gear 13, a threaded tube 14 is installed. At one end of the threaded tube 14, a movable block 15 is installed. At both ends of the outer side of the movable block 15 away from the threaded tube 14, limiting grooves 1501 are symmetrically opened. On the outer side of the movable block 15 and on both sides of the threaded rod 12, support rods 16 are symmetrically installed. On the outer side of the movable block 15 and between the two limiting grooves 1501, a plurality of damping rods 17 are installed. At the end of the damping rod 17 away from the movable block 15, a scraping plate 18 is installed.

[0028] Specifically, referring to Figure 4 and Figure 5 , the first bevel gear 11 meshes with the second bevel gear 13, and the end of the threaded rod 12 away from the second bevel gear 13 penetrates through the inner side wall of the cavity 901 and extends to the outside of the equipment box 9 and then extends into the interior of the threaded tube 14. The inner side wall of the threaded tube 14 is threadedly connected to the outer ring surface of the threaded rod 12, so as to ensure that the rotation of the first bevel gear 11 driven by the servo motor 10 synchronously drives the rotation of the two second bevel gears 13, and the rotation of the two second bevel gears 13 respectively drives the synchronous rotation of the two threaded rods 12, so that the threaded rod 12 moves inside the threaded tube 14 to drive the movable block 15 to move.

[0029] Further, a water pump is provided inside the water tank 4, and the connecting pipe 6 is connected to the water pump at the inner bottom of the water tank 4, so as to ensure that the water inside the water tank 4 is pumped through the connecting pipe 6 into the inner part of the water distribution pipe 7 and then sprayed onto the outer ring surface of the pressing wheel 2 through a plurality of nozzles 8.

[0030] Further, one end of the support rod 16 passes through the movable block 15 and extends into the limiting groove 1501, and the outer ring surface of the support rod 16 is slidably connected with the inner part of the movable block 15, so as to ensure that the movement of the movable block 15 outside the two support rods 16 increases the stability of the movement of the threaded rod 12 in the threaded pipe 14 to drive the movable block 15 to move.

[0031] Further, a limiting block is installed at one end of the support rod 16 located inside the limiting groove 1501, and when the movable block 15 slides to the end of one end of the support rod 16, the scraping plate 18 just fits the outer ring surface of the pressing wheel 2, so as to ensure that the distance between the scraping plate 18 and the pressing wheel 2 is adjusted by the movement of the movable block 15 outside the support rod 16.

[0032] Specifically, referring to Figure 4 As shown, the length of the scraping plate 18 is the same as the width of the pressing wheel 2, and multiple groups of damping rods 17 are arranged on the scraping plate 18 to play a buffering role for the scraping plate 18, so as to ensure that the problem that the scraping plate 18 is damaged due to excessive force when scraping the soil on the pressing wheel 2 is avoided by arranging multiple groups of damping rods 17 to play a buffering role for the scraping plate 18.

[0033] The working process of the present utility model: When using a double-drum roller designed by this solution, during the use of the double-drum roller, when the outer surfaces of the two pressing wheels 2 are adhered with soil, the first bevel gear 11 is driven to rotate by the servo motor 10, synchronously driving the two second bevel gears 13 to rotate. The two second bevel gears 13 rotate respectively to drive the two threaded rods 12 to rotate synchronously, so that the threaded rods 12 move in the threaded pipes 14 to drive the movable blocks 15 to move. The movement of the movable blocks 15 outside the two support rods 16 increases the stability of the movement of the threaded rods 12 in the threaded pipes 14 to drive the movable blocks 15 to move. The distance between the scraping plate 18 and the pressing wheel 2 is adjusted by the movement of the movable blocks 15 outside the support rods 16, so that the scraping plate 18 is close to the pressing wheel 2 to scrape the soil. The water inside the water tank 4 is pumped through the connecting pipe 6 into the inner part of the water distribution pipe 7 and then sprayed onto the outer ring surface of the pressing wheel 2 through a plurality of nozzles 8 to clean the pressing wheel 2. The water inside the water tank 4 can be added through the water inlet 5. The problem that the scraping plate 18 is damaged due to excessive force when scraping the soil on the pressing wheel 2 is avoided by arranging multiple groups of damping rods 17 to play a buffering role for the scraping plate 18.

[0034] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
