Description

Technical Field

[0001] This invention relates to the field of foundation construction technology, and in particular to a foundation leveling device for highway construction. Background Technology

[0002] In highway construction, foundation leveling is a crucial step in ensuring the stability and durability of the engineering structure. Traditional highway foundation leveling typically employs manual labor or simple mechanical equipment such as bulldozers and road rollers. However, these methods have several drawbacks. Hard or compacted foundation soil is difficult to break up effectively with traditional equipment, leading to unsatisfactory leveling results and affecting the bearing capacity and uniformity of the foundation. Manually operated or single-function mechanical equipment cannot simultaneously complete crushing, preliminary leveling, and compaction operations, requiring multiple repetitions and resulting in low efficiency. Existing equipment largely relies on manual adjustment of crushing depth and compaction intensity, making it difficult to precisely control construction quality and resulting in high labor intensity. Different geological conditions (such as soft soil, hard soil, and mixed sand and gravel layers) require different construction methods, and traditional equipment struggles to flexibly switch between crushing and compaction modes. Currently, some foundation leveling equipment on the market attempts to combine crushing and compaction functions, but these still suffer from complex structures, inconvenient operation, and low power transmission efficiency. Therefore, there is an urgent need for a high-efficiency highway foundation construction device that integrates crushing, leveling and compaction functions, capable of automatically adjusting the construction mode, adapting to different geological conditions, and improving the quality and efficiency of foundation leveling. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention adopts the following technical solution: a road construction foundation leveling device, comprising a leveling mechanism for leveling the road foundation, the leveling mechanism comprising a main frame, a rotating frame rotatably mounted on the main frame, and a crushing mechanism for breaking the road foundation and a compaction mechanism for rolling the road foundation on the leveling mechanism. The rolling mechanism includes a worm gear rotatably mounted on the main frame, and a lifting gear is fixedly mounted on the worm gear.

[0004] Furthermore, the leveling mechanism also includes a power motor fixedly installed inside the main frame. A power gear is fixedly installed on the motor shaft of the power motor. An input wheel, a middle transmission wheel, and an output wheel are rotatably installed inside the main frame. An inner transmission belt is wound around the input wheel, the middle transmission wheel, and the output wheel. A mating gear is fixedly installed on the output wheel. The input wheel meshes with the power gear.

[0005] Furthermore, the main frame is provided with two moving modules. Each moving module includes a drive wheel rotatably mounted on a central transmission wheel, and two traveling wheels rotatably mounted on the main frame. A traveling belt is wrapped around the drive wheel and the two traveling wheels.

[0006] Furthermore, four guide columns are slidably mounted on the main frame, a lower pressure plate is fixedly mounted below the guide columns, a rotating rod is fixedly mounted on the central transmission wheel, an inner rotating rod is rotatably mounted on the rotating rod, and the inner rotating rod is rotatably mounted with the lower pressure plate.

[0007] During construction, the main frame is moved onto the highway foundation. The power motor drives the power gear to rotate, which in turn drives the input wheel to rotate. This, in turn, drives the middle drive wheel and output wheel to rotate via the inner drive belt. The output wheel drives the mating gear to rotate, and the middle drive wheel drives the drive wheel and rotating rod to rotate. The rotation of the drive wheel drives the traveling belt to rotate, which in turn drives the device to move. The rotation of the rotating rod drives the inner rotating rod to rotate, which in turn drives the lower pressure plate and guide column to rise and fall. The lower pressure plate then levels the highway foundation.

[0008] Furthermore, the crushing mechanism includes a lifting frame slidably mounted on the main frame, a lifting rack fixedly mounted on the lifting frame, the lifting rack meshing with a lifting gear, two transmission wheels rotatably mounted on the lifting frame, a paving belt wrapped around the two transmission wheels, multiple paving ramps provided on the paving belt, and a slope surface provided on the paving ramps, and an external mating gear fixedly mounted on the transmission wheel next to the lifting rack.

[0009] Furthermore, three crushing blocks and three insertion blocks are slidably installed on the lifting frame, with the crushing blocks and insertion blocks arranged alternately. Multiple crushing heads are fixedly installed at the bottom of the crushing blocks, and multiple insertion heads are fixedly installed at the bottom of the insertion blocks. A crushing spring is provided between the crushing blocks and the lifting frame, and an insertion spring is provided between the insertion blocks and the lifting frame. A crushing column is fixedly installed on the crushing blocks, and an insertion column is fixedly installed on the insertion blocks. The crushing column and the insertion column respectively cooperate with the actuating ramp.

[0010] Furthermore, four lifting cylinders are slidably installed below the lifting frame, and an inner spring is provided between the lifting cylinders and the lifting frame. Two wheel seats are rotatably installed below the lifting cylinders, and front wheels are rotatably installed on the wheel seats.

[0011] When the lifting frame descends, it slides downward relative to the main frame, causing the crushing head and insert head to contact the road subgrade. At this time, the connecting gear meshes with the outer connecting gear, which drives the outer connecting gear and the transmission wheel to rotate, causing the actuating belt to rotate clockwise. This causes the actuating block to move. When the slope surface of the actuating block contacts the crushing column, it causes the crushing column, crushing block, and crushing head to rise, and the crushing spring is compressed. When the actuating block disengages from the crushing column, the crushing spring rebounds, causing the crushing block and crushing head to descend rapidly. Similarly, when the slope surface of the actuating block contacts the inserting column, it causes the inserting column, inserting block, and inserting head to rise, and the inserting spring is compressed. When the actuating block disengages from the inserting column, the inserting spring rebounds, causing the inserting block and inserting head to descend rapidly. The crushing head breaks up the hard subgrade soil, and the inserting head inserts into the subgrade soil, destroying the original soil structure, thus achieving the crushing of the subgrade soil.

[0012] Furthermore, the rolling mechanism includes a pressure roller rotatably mounted on a rotating frame, a winding wheel fixedly mounted on a worm gear, one end of a steel wire rope wound on the winding wheel, the other end of the steel wire rope fixedly mounted to the rotating frame, and multiple guide wheels rotatably mounted on the main frame to support the steel wire rope.

[0013] Furthermore, a switching module is provided on the main frame. The switching module includes a switching motor fixedly installed on the main frame. A switching gear is fixedly installed on the motor shaft of the switching motor. A switching shaft is rotatably installed on the main frame. A lower gear and a worm are fixedly installed on the switching shaft. The lower gear meshes with the switching gear, and the worm meshes with the worm wheel.

[0014] The switching motor rotates, driving the switching gear to rotate, which in turn drives the lower gear, switching shaft, and worm gear to rotate. The worm gear drives the worm wheel, lifting gear, and winding wheel to rotate. When the lifting gear drives the lifting rack and lifting frame to descend, it drives the rotating frame and pressure roller to rotate upward via the wire rope, lifting the pressure roller off the ground. When the lifting gear drives the lifting rack and lifting frame to rise, the rotating frame and pressure roller rotate downward, and the pressure roller contacts the foundation. When the lifting frame descends, it breaks up the foundation soil through the insertion block and insertion head, and then performs preliminary leveling of the soil through the lower pressure plate. Subsequently, the lifting frame rises, and the pressure roller compacts and levels the ground.

[0015] The beneficial effects of this invention compared with the prior art are: (1) By integrating the crushing mechanism, leveling mechanism and compaction mechanism, this invention can complete the crushing, preliminary leveling and compaction of the road foundation in one go, avoiding the cumbersome process of changing equipment multiple times in traditional construction, and significantly improving construction efficiency; (2) This invention adopts the coordinated control of the power motor, switching motor and transmission system to realize the automatic switching of crushing, leveling and compaction modes, reduce manual adjustment, reduce labor intensity, and improve construction accuracy to ensure the quality of foundation leveling; (3) This invention can effectively crush hard soil or loose sand and gravel layers by using the liftable crushing block and insertion block in combination with the spring rebound impact structure; at the same time, the compaction mechanism can adjust the height to adapt to different compaction requirements, so that the device can work stably in soft soil, hard soil or mixed foundation.

Detailed Implementation

[0025] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0026] Example: Reference Figures 1-8 A road construction foundation leveling device includes a leveling mechanism for leveling the road foundation. The leveling mechanism includes a main frame 101, a rotating frame 105 rotatably mounted on the main frame 101, and a crushing mechanism for breaking the road foundation and a compaction mechanism for rolling the road foundation. The compaction mechanism includes a worm gear 308 rotatably mounted on the main frame 101, and a lifting gear 309 is fixedly mounted on the worm gear 308.

[0027] like Figure 2 , Figure 3As shown, the leveling mechanism also includes a power motor 106 fixedly installed in the main frame 101. A power gear 107 is fixedly installed on the motor shaft of the power motor 106. An input wheel 108, a middle transmission wheel 110, and an output wheel 111 are rotatably installed in the main frame 101. An inner transmission belt 109 is wound around the input wheel 108, the middle transmission wheel 110, and the output wheel 111. A mating gear 112 is fixedly installed on the output wheel 111. The input wheel 108 meshes with the power gear 107.

[0028] like Figure 2 , Figure 3 As shown, the main frame 101 is provided with two moving modules. The moving module includes a drive wheel 104 rotatably mounted on the central drive wheel 110, and two traveling wheels 102 rotatably mounted on the main frame 101. The drive wheel 104 and the two traveling wheels 102 are wrapped with a traveling belt 103.

[0029] like Figure 2 , Figure 3 As shown, four guide columns 116 are slidably installed on the main frame 101, and a lower pressure plate 115 is fixedly installed below the guide columns 116. A rotating rod 113 is fixedly installed on the middle transmission wheel 110, and an inner rotating rod 114 is rotatably installed on the rotating rod 113. The inner rotating rod 114 is rotatably installed with the lower pressure plate 115.

[0030] During construction, the main frame 101 is moved onto the highway foundation. The power motor 106 drives the power gear 107 to rotate, which in turn drives the input wheel 108 to rotate. This, in turn, drives the intermediate transmission wheel 110 and the output wheel 111 to rotate via the inner transmission belt 109. The output wheel 111 drives the mating gear 112 to rotate, and the intermediate transmission wheel 110 drives the drive wheel 104 and the rotating rod 113 to rotate. The rotation of the drive wheel 104 drives the travel belt 103 to rotate, which in turn drives the device to move. The rotation of the rotating rod 113 drives the inner rotating rod 114 to rotate, which in turn drives the lower pressure plate 115 and the guide column 116 to rise and fall. The lower pressure plate 115 is used to level the highway foundation.

[0031] like Figures 4-6 As shown, the crushing mechanism includes a lifting frame 201 slidably mounted on the main frame 101. A lifting rack 202 is fixedly mounted on the lifting frame 201. The lifting rack 202 meshes with a lifting gear 309. Two transmission wheels 207 are rotatably mounted on the lifting frame 201. A toggle belt 209 is wound around the two transmission wheels 207. Multiple toggle ramps 210 are provided on the toggle belt 209. A ramp surface is provided on the toggle ramps 210. An external mating gear 208 is fixedly mounted on the transmission wheel 207 next to the lifting rack 202.

[0032] like Figures 4-6As shown, three crushing blocks 211 and three insertion blocks 214 are slidably installed on the lifting frame 201. The crushing blocks 211 and the insertion blocks 214 are arranged alternately. Multiple crushing heads 212 are fixedly installed at the bottom of the crushing blocks 211, and multiple insertion heads 215 are fixedly installed at the bottom of the insertion blocks 214. A crushing spring 217 is provided between the crushing blocks 211 and the lifting frame 201, and an insertion spring 218 is provided between the insertion blocks 214 and the lifting frame 201. A crushing column 213 is fixedly installed on the crushing blocks 211, and an insertion column 216 is fixedly installed on the insertion blocks 214. The crushing column 213 and the insertion column 216 respectively cooperate with the actuating ramp 210.

[0033] like Figures 4-6 As shown, four lifting cylinders 203 are slidably installed below the lifting frame 201. An inner spring 206 is provided between the lifting cylinder 203 and the lifting frame 201. Two wheel seats 204 are rotatably installed below the lifting cylinder 203, and a front wheel 205 is rotatably installed on the wheel seat 204.

[0034] When the lifting frame 201 is lowered, it slides downward relative to the main frame 101, causing the crushing head 212 and the insertion head 215 to contact the roadbed. At this time, the docking gear 112 meshes with the outer docking gear 208. The docking gear 112 drives the outer docking gear 208 and the transmission wheel 207 to rotate, which in turn drives the actuating belt 209 to rotate clockwise, thereby driving the actuating ramp 210 to move. When the slope surface of the actuating ramp 210 contacts the crushing column 213, it causes the crushing column 213, the crushing block 211, and the crushing head 212 to rise, and the crushing spring 217 is compressed. When the actuating ramp 210 contacts the crushing column 213, it causes the crushing column 213, the crushing block 211, and the crushing head 212 to rise. 3. After separation, the breaking spring 217 rebounds, causing the breaking block 211 and the breaking head 212 to descend rapidly. Similarly, when the slope surface of the agitator block 210 contacts the insertion post 216, it causes the insertion post 216, the insertion block 214, and the insertion head 215 to rise, and the insertion spring 218 is compressed. When the agitator block 210 separates from the insertion post 216, the insertion spring 218 rebounds, causing the insertion block 214 and the insertion head 215 to descend rapidly. The breaking head 212 breaks the hard foundation soil, and the insertion head 215 inserts into the foundation soil, destroying the original soil structure and achieving the breaking of the foundation soil.

[0035] like Figure 7 , Figure 8 As shown, the rolling mechanism includes a pressure roller 301 rotatably mounted on a rotating frame 105, a winding wheel 310 fixedly mounted on a worm gear 308, one end of a steel wire rope 302 wound on the winding wheel 310, the other end of the steel wire rope 302 fixedly mounted to the rotating frame 105, and multiple guide wheels 311 rotatably mounted on the main frame 101, the guide wheels 311 supporting the steel wire rope 302.

[0036] like Figure 7 , Figure 8As shown, a switching module is provided on the main frame 101. The switching module includes a switching motor 303 fixedly installed on the main frame 101. A switching gear 304 is fixedly installed on the motor shaft of the switching motor 303. A switching shaft 305 is rotatably installed on the main frame 101. A lower gear 306 and a worm gear 307 are fixedly installed on the switching shaft 305. The lower gear 306 meshes with the switching gear 304, and the worm gear 307 meshes with the worm wheel 308.

[0037] The switching motor 303 rotates, driving the switching gear 304 to rotate, which in turn drives the lower gear 306, the switching shaft 305, and the worm gear 307 to rotate. The worm gear 307 drives the worm wheel 308, the lifting gear 309, and the winding wheel 310 to rotate. When the lifting gear 309 drives the lifting rack 202 and the lifting frame 201 to descend, the steel wire rope 302 drives the rotating frame 105 and the pressure roller 301 to rotate upward, lifting the pressure roller 301 off the ground. When the lifting gear 309 drives the lifting rack 202 and the lifting frame 201 to rise, the rotating frame 105 and the pressure roller 301 rotate downward, and the pressure roller 301 contacts the foundation. When the lifting frame 201 descends, the foundation soil is broken by the insertion block 214 and the insertion head 215. Then, the soil is initially leveled by the lower pressure plate 115. Subsequently, the lifting frame 201 rises, and the ground is compacted and leveled by the pressure roller 301.

[0038] The working principle of the road construction foundation leveling equipment disclosed in this invention is as follows: During construction, the main frame 101 is moved onto the road foundation. The power motor 106 drives the power gear 107 to rotate, which in turn drives the input wheel 108 to rotate. This, in turn, drives the middle transmission wheel 110 and the output wheel 111 to rotate via the inner transmission belt 109. The output wheel 111 drives the mating gear 112 to rotate. The middle transmission wheel 110 drives the drive wheel 104 and the rotating rod 113 to rotate. The rotation of the drive wheel 104 drives the traveling belt 103 to rotate. The traveling belt 103 drives the device to move. The rotation of the rotating rod 113 drives the inner rotating rod 114 to rotate, which in turn drives the lower pressure plate 115 and the guide column 116 to rise and fall. The lower pressure plate 115 levels the road foundation. The rotation of the switching motor 303 drives the switching gear 304 to rotate, which in turn drives the lower gear 306, the switching shaft 305, and the worm gear 307 to rotate. The worm gear 307 drives the worm wheel 308, the lifting gear 309, and the winding wheel 310 to rotate. When the lifting gear 309 drives the lifting rack 202 and the lifting frame 201 to descend, it drives the rotating frame 105 and the pressure roller 301 to rotate upward through the wire rope 302, lifting the pressure roller 301 off the ground. When the lifting frame 201 descends, it slides downward relative to the main frame 101, causing the crushing head 212 and the insertion head 215 to contact the roadbed. At this time, the docking gear 112 meshes with the outer docking gear 208. The docking gear 112 drives the outer docking gear 208 and the transmission wheel 207 to rotate, which drives the actuating belt 209 to rotate clockwise, thereby driving the actuating ramp 210 to move. When the slope surface of the movable ramp 210 contacts the breaking column 213, it causes the breaking column 213, breaking block 211, and breaking head 212 to rise, and the breaking spring 217 is compressed. When the movable ramp 210 disengages from the breaking column 213, the breaking spring 217 rebounds, causing the breaking block 211 and breaking head 212 to descend rapidly. Similarly, when the slope surface of the movable ramp 210 contacts the insertion column 216, it causes the insertion column 216, insertion block 214, and insertion head 215 to rise, and the insertion spring 218 is compressed. When the movable ramp 210 disengages from the insertion column 216, the insertion spring 218 rebounds, causing the insertion block 214 and insertion head 215 to descend rapidly. The breaking head 212 breaks the hard foundation soil, and the insertion head 215 inserts into the foundation soil, destroying the original soil structure and achieving the breaking of the foundation soil. When the lifting gear 309 drives the lifting rack 202 and the lifting frame 201 to rise, the rotating frame 105 and the pressure roller 301 rotate downwards. The pressure roller 301 contacts the foundation. When the lifting frame 201 descends, the foundation soil is broken by the insertion block 214 and the insertion head 215. Then, the soil is initially leveled by the lower pressure plate 115. After that, the lifting frame 201 rises and the ground is rolled and leveled by the pressure roller 301.
