Description

Technical Field

[0001] This utility model relates to a road roller, and more particularly to a road manually steering road roller. Background Technology

[0002] A road roller is a type of road construction equipment. Within the broader category of engineering machinery, road rollers fall under the category of road equipment and are widely used in compaction operations for large-scale projects such as highways, railways, airport runways, dams, and stadiums. They can compact sandy, semi-cohesive, and cohesive soils, as well as roadbed stabilized soils and asphalt concrete pavement layers. Road rollers utilize their own weight to perform various compaction operations, causing permanent deformation and densification of the compacted layer. Currently, existing road rollers are relatively large, making them inconvenient for backfilling cable trenches and finishing road edges. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a manual steering road roller, which solves the problem that the existing road rollers are too large and inconvenient for backfilling cable trenches and compacting road edges.

[0004] The technical solution adopted by this utility model to solve the above-mentioned problems is as follows:

[0005] A road roller with manual steering includes a frame 1, a handle 2, a diesel engine 3, a support plate A4, a hydraulic pump 5, a hydraulic motor 6, sprockets A7 and B8, rollers A9 and B10, a support plate B11, sprockets C12 and C13, sprockets D14, a T-plate 15, a connecting plate 16, annular chains A17 and B18. The handle 2 is fixed to the rear of the frame 1. The diesel engine 3 is fixed to the rear of the upper surface of the frame 1. The support plate A4 is fixed to the left side of the rear of the upper surface of the frame 1. The hydraulic pump 5 is fixed to the upper part of the support plate A4, and the main shaft of the hydraulic pump 5 rotates through the support plate A4. The main shaft end of the hydraulic pump 5 is fixedly connected to the power output end of the diesel engine 3. The hydraulic motor 6 is fixed to the lower left side of the frame 1, and the main shaft of the hydraulic motor 6 rotates through the frame 1. The hydraulic motor 6 has sprockets A7 and B8 fixedly mounted on its main shaft. Rollers A9 and B10 are mounted on the lower side of the frame 1. The lower part of the support plate B11 is rotatably connected to the right side of roller A9. Sprocket C12 is fixedly mounted on the left side of roller A9. The lower part of the support plate C13 is rotatably connected to the right side of roller B10. Sprocket D14 is fixedly mounted on the left side of roller B10. The upper parts of the support plates B11 and C13 are fixedly connected to the right side of the frame 1. The left parts of rollers A9 and B10 rotatably pass through T-shaped plate 15. The upper part of the connecting plate 16 is fixedly connected to the left side of the frame 1. The T-shaped plate 15 is fixedly connected to the connecting plate 16. Sprockets A7 and D14 are driven by meshing with an annular chain B18. Sprockets C12 and B18 are driven by meshing with an annular chain A17.

[0006] A grooved wheel A20 is fixedly sleeved on the output shaft of the diesel engine 3. A vibrator 21 is fixedly installed at the front of the frame 1. A grooved wheel B22 is fixedly installed at the power input end of the vibrator 21. The same annular belt 23 is sleeved between the grooved wheel A20 and the grooved wheel B22. The vibrator 21 improves the road roller's compaction effect.

[0007] The sprockets A7, B8, C12, D14, T-shaped plate 15, and ring chains A17 and B18 are all covered by the same protective cover 19, and the protective cover 19 is fixedly connected to the connecting plate 16. The protective cover 19 prevents the rotating sprockets A7, B8, C12, D14, A17, and B18 from squeezing people.

[0008] An oil tank 24 and a water tank 25 are fixedly installed at the front of the frame 1, and the oil tank 24 and the water tank 25 are fixedly connected. The water tank 25 is connected and fixed to the diesel engine 3 through an inlet pipe and an outlet pipe. The oil tank 24 supplies oil to the hydraulic pump 5 through an oil inlet pipe. The hydraulic pump 5 supplies oil to the hydraulic motor 6 through an oil inlet pipe. The hydraulic motor 6 returns oil to the hydraulic pump 5 through a return oil pipe. The hydraulic pump 5 returns oil to the oil tank 24 through a return oil pipe. The oil tank 24 facilitates the supply of oil to the hydraulic pump 5 and facilitates the cooling of the diesel engine 3 through the water tank 25.

[0009] An n-shaped component 26 is fixedly installed in the middle of the frame 1 to facilitate the lifting of the road roller through the n-shaped component 26.

[0010] The working principle of this utility model is as follows: add an appropriate amount of hydraulic oil to the oil tank and an appropriate amount of clean water to the water tank. Use the N-shaped component to lift the manually steering road roller to the position where it needs to work. Start the diesel engine. The water in the water tank cools the diesel engine through the inlet and outlet pipes.

[0011] The output shaft of the diesel engine drives the grooved wheel A to rotate, and the grooved wheel A drives the grooved wheel B to rotate through the annular belt. The grooved wheel B drives the vibrator to run, and the vibrator transmits the vibration force to the rollers A and B through the frame, support plate B, support plate C, and connecting plate.

[0012] The diesel engine's power output shaft drives the hydraulic pump. The oil tank supplies oil to the hydraulic pump through the inlet pipe, and the hydraulic pump supplies oil to the hydraulic motor through the inlet pipe. The hydraulic motor returns oil to the hydraulic pump through the return pipe, and the hydraulic pump returns oil to the oil tank through the return pipe. The hydraulic motor rotates, and the hydraulic motor's main shaft drives sprockets A and B to rotate. Sprockets A and D are driven by a ring chain B, and sprocket C and ring chain B are driven by a ring chain A. Sprocket D drives roller B to rotate, and sprocket C drives roller A to rotate. Rollers A and B directly or indirectly drive the connected components to work on the ground that needs to be compacted. The vibration force of the vibrator increases the compaction effect of rollers A and B.

[0013] When the manual steering roller needs to turn, the handrail is lifted, the handrail drives the frame, and the frame directly or indirectly drives the connected parts. Roller A leaves the table, and roller B rubs against the ground. The manual steering roller completes the turn. After the handrail is lowered, roller B continues to work after contacting the ground.

[0014] After the work is completed, turn off the diesel engine and use the N-shaped tool to lift the manual steering roller to the required position.

[0015] The beneficial effects of this utility model are as follows: 1. The road roller is lightweight, can be steered by lifting the handle, and has low production costs. 2. The vibrator improves the compaction effect of the road roller. 3. The protective cover prevents injuries from being crushed by rotating sprockets A, B, C, D, and ring chains A and B. 4. The oil tank facilitates oil supply to the hydraulic pump, and the water tank facilitates cooling of the diesel engine. 5. The road roller can be easily lifted using an N-shaped lifting device.
