Technical Field

[0001] The utility model relates to the field of transportation equipment, in particular to an earthwork transportation device for engineering construction. Background Art

[0002] Municipal engineering refers to municipal infrastructure construction projects, including all kinds of public facilities in cities, regions or towns, including roads, bridges, tunnels, water supply and drainage facilities. The construction and maintenance of these facilities are the responsibility of the government to ensure the quality of life of residents and the development of the city. The construction and maintenance of municipal engineering are essential to the normal operation of the city. They provide residents with necessary infrastructure, promote economic development, and improve the quality of life of residents. During the construction process, the earthwork that needs to be excavated or backfilled needs to be transported by earthmoving transportation equipment.

[0003] Generally, small-scale earthwork is transported by a wheelbarrow. The wheelbarrow includes a bucket with wheels installed at the bottom and a handlebar on one side of the bucket. When in use, the earth to be transported is shoveled into the bucket, and the wheels are turned by pushing or pulling the handlebars to transport the earth. Due to the complex terrain of the construction site, downhill sections may be encountered during the use of the wheelbarrow. A wheelbarrow filled with earth will be difficult to control on the downhill section, and the user needs to apply a certain resistance to control the wheelbarrow. Therefore, this type of wheelbarrow is inconvenient to use on the downhill section.

[0004] Therefore, it is necessary to provide a new earthwork transportation device for engineering construction to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an earthwork transportation device for engineering construction.

[0012] Preferably, the surface of the friction column is provided with a plurality of strips for increasing friction.

[0013] Compared with the related art, the earthwork transportation device for engineering construction provided by the utility model has the following beneficial effects:

[0014] When reaching a downhill section, the driving component drives the rotating column to rotate. The rotation of the rotating column will cause the moving block to move. The moving block drives the two friction columns to squeeze the surface of the roller through the two clamping plates and the moving plate, so that the resistance rods at both ends of the friction column move in the through groove respectively. As the distance between the two sides of the inner wall of the through groove gradually decreases, the resistance rod will cause the inner wall of the through groove to squeeze the surface of the resistance rod when moving in the through groove, so that the friction force of the inner wall of the through groove on the surface of the resistance rod increases, thereby increasing the resistance to rotation of the friction column, thereby increasing the resistance to rotation of the roller that is in contact with the friction column. Through the above structure, the resistance to rotation of the two rollers can be increased when encountering a downhill section, which is convenient for the use of the device in a downhill section to a certain extent.

[0024] The resistance mechanism includes a rotating column 5, a moving block 6, a moving plate 7, two clamping plates 8 and two friction columns 9. A second fixed block 10 is provided at the bottom of the bucket 1. One end of the rotating column 5 is movably connected to one side of the first fixed block 4. The end of the rotating column 5 away from the first fixed block 4 passes through one side of the second fixed block 10. A thread is provided on the surface of the rotating column 5.

Resistance rods 11 are respectively provided at both ends of the two friction columns 9. Through grooves 12 are respectively opened on the opposite sides of the two clamping plates 8. The distance between the two sides of the inner wall of the through groove 12 gradually decreases.

As the distance between the two sides of the inner wall of the through groove 12 gradually decreases, when the resistance rod 11 moves in the through groove 12, the inner wall of the through groove 12 squeezes the surface of the resistance rod 11, so that the friction force of the inner wall of the through groove 12 on the surface of the resistance rod 11 increases, thereby increasing the resistance to the rotation of the friction column 9, thereby increasing the resistance to the rotation of the roller 3 in contact with the friction column 9;

[0025] The driving assembly includes a rotating sleeve 13, a connecting column 14 and a fixed sleeve 15. A handlebar 16 is provided on one side of the truck 1. A first bevel gear 17 is provided on the surface of the handlebar 16. The rotating sleeve 13 is provided on the surface of the handlebar 16.

The third bevel gear 19 is fixedly arranged at one end of the rotating column 5 away from the first fixed block 4, and the third bevel gear 19 is meshed with the second bevel gear 18 at the bottom of the connecting column 14. By rotating the rotating sleeve 13, the first bevel gear 17 is driven to rotate, so that the first bevel gear 17 drives the second bevel gear 18 at the top of the connecting column 14 to rotate, and drives the second bevel gear 18 at the bottom thereof to rotate through the connecting column 14, so that the third bevel gear 19 is rotated.

[0028] The working principle provided by the utility model is as follows: when reaching the downhill section, the first bevel gear 17 is driven to rotate by rotating the rotating sleeve 13, so that the first bevel gear 17 drives the second bevel gear 18 at the top of the connecting column 14 to rotate, and drives the second bevel gear 18 at the bottom thereof to rotate through the connecting column 14, thereby causing the third bevel gear 19 to rotate.

Since the distance between the two sides of the inner wall of the through groove 12 is gradually reduced, when the resistance rod 11 moves in the through groove 12, the inner wall of the through groove 12 squeezes the surface of the resistance rod 11, so that the friction force of the inner wall of the through groove 12 on the surface of the resistance rod 11 increases, thereby increasing the resistance to the rotation of the friction column 9, thereby increasing the resistance to the rotation of the roller 3 that is in contact with the friction column 9.
