Abstract
Description
Technical Field
[0001] This utility model belongs to the field of highway construction technology, specifically relating to a compaction device for highway construction. Background Technology
[0002] Highway construction refers to the overall work of highway network planning, highway surveying and design, highway construction, maintenance, and management. To improve the load-bearing capacity and stability of highways, reduce soil settlement and seepage, and enhance their waterproofing, the compaction quality of the subgrade and pavement is one of the most important intrinsic indicators of road engineering construction quality management. Only by fully compacting the subgrade and pavement structural layers can the strength, rigidity, stability, and smoothness of the subgrade and pavement be guaranteed, thereby extending their service life.
[0003] In existing technologies, after the compaction device is used, a large amount of soil adheres to the bottom of the compaction plate. The height of the compaction plate is mostly fixed, which makes it impossible to compact the road surface at different heights according to the needs. Therefore, there is an urgent need to design a compaction device for highway construction to solve these problems. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model discloses a compaction device for highway construction.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] A compaction device for highway construction includes a base, a moving mechanism above the base, and a lifting compaction mechanism above the moving mechanism.
[0007] The lifting and compaction mechanism includes a vertical platform fixedly mounted on a moving mechanism. A vertical screw is installed vertically inside the platform, and a lifting platform is installed on the outer surface of the screw. A second motor is installed at one end of the screw. A horizontal plate is installed on the lifting platform, and a lifting hydraulic cylinder is installed on the horizontal plate. The power extension end of the lifting hydraulic cylinder is equipped with the compactor body. A connecting buffer plate is installed at the power end of the compactor body. A compaction plate is installed below the connecting buffer plate. A telescopic scraper is installed below the compaction plate. An electric telescopic rod is installed on the telescopic scraper. An L-shaped plate is installed on the electric telescopic rod. Water spraying components are installed on the front and rear sides of the compaction plate.
[0008] Preferably, the moving mechanism includes a mounting platform fixedly installed on the front and rear sides of the base, a positioning component is provided on the mounting platform, a transverse lead screw is transversely arranged on the front and rear sides above the base, a first motor is provided at one end of the transverse lead screw, a limit guide rod is provided on one side of the transverse lead screw, and a moving platform is provided on the outer surface of the transverse lead screw and the limit guide rod.
[0009] Preferably, the water spraying assembly includes water tanks disposed on the front and rear sides of the compaction plate, and a spray nozzle is provided at the water outlet of the water tank.
[0010] Preferably, a damping spring is provided between the connecting buffer plate and the compaction plate.
[0011] Preferably, the positioning component includes a positioning hydraulic cylinder mounted on the mounting platform, and the power extension end of the positioning hydraulic cylinder is provided with a positioning pin.
[0012] Preferably, the base is provided with casters on the front and rear sides below it, and a counterweight is provided on the base.
[0013] The beneficial effects are:
[0014] This utility model discloses a compaction device for highway construction. Through a lifting and compaction mechanism, a second motor drives a vertical screw to rotate, which in turn drives the horizontal platform, lifting hydraulic cylinder, compactor body, connecting buffer plate, and compaction plate to move up and down. When the lifting hydraulic cylinder, compactor body, and compaction plate move to a certain position, they stop. The lifting hydraulic cylinder is then activated to push the compactor body, connecting buffer plate, and compaction plate a certain distance from the road surface to be compacted. The compactor body then drives the connecting buffer plate and compaction plate to compact the road surface. When the soil under the compaction plate accumulates to a certain amount, an electric telescopic rod pushes a telescopic scraper to remove it. Simultaneously, a water spray assembly removes dust during road surface compaction, ensuring the compaction effect. The increased lifting and lowering of the compaction plate also improves compaction efficiency and makes the device highly practical. Attached Figure Description

[0024] In this embodiment: the moving mechanism 2 includes a mounting platform 201 fixedly mounted on the front and rear sides of the base 1. A positioning component is mounted on the mounting platform 201. A transverse lead screw 206 is horizontally mounted on the front and rear sides above the base 1.

The positioning component includes a positioning hydraulic cylinder 202 mounted on the mounting platform 201. A positioning pin 203 is mounted on the power extension end of the positioning hydraulic cylinder 202. Moving wheels 204 are mounted on the front and rear sides below the base 1, and a counterweight 205 is mounted on the base 1. The counterweight 205 is used to maintain the balance of the device during compaction.
[0025] In this embodiment: the lifting and compaction mechanism 3 includes a vertical platform 301 fixedly mounted on the moving mechanism 2. A vertical screw 302 is vertically mounted inside the vertical platform 301. A lifting platform 303 is mounted on the outer surface of the vertical screw 302. A second motor 304 is mounted on one end of the vertical screw 302. A horizontal plate 305 is horizontally mounted on the lifting platform 303. A lifting hydraulic cylinder 306 is mounted on the horizontal plate 305. A compaction machine body 307 is mounted on the power extension end of the lifting hydraulic cylinder 306. A shell is provided on the outer surface of the compaction machine body 307. A connecting buffer plate 308 is provided on the power end of the compaction machine body 307. A compaction plate 310 is provided below the connecting buffer plate 308. A telescopic scraper 3121 is provided below the compaction plate 310. An electric telescopic rod 312 is provided on the telescopic scraper 3121. An L-shaped plate 311 is mounted on the electric telescopic rod 312.

[0026] Working Principle: In use, the device is first moved to the location requiring compaction using the moving wheels 204, then stopped. The positioning hydraulic cylinder 202 is activated, pushing the positioning pin 203 below ground level to position the device. The first motor 207 is then activated, rotating the horizontal lead screw 206, which moves the moving platform 209. Simultaneously, the lifting and compaction mechanism 3 moves to the left side of the base 1, and the compaction plate 310 mounted on the lifting and compaction mechanism 3 moves out of the left side of the base 1. The counterweight block 205 balances the load. The second motor 304 mounted on the vertical platform 301 is then activated, rotating the vertical lead screw 302, which drives the lifting platform 303 and the horizontal platform 305 to rise and fall, and also drives the lifting hydraulic cylinder 306 and the compactor itself. The compactor body 307 and the tamping plate 310 are lowered. The lifting hydraulic cylinder 306 is activated to push the compactor body 307 and the tamping plate 310 close to the ground to be compacted. When they are close, the compactor body 307 is activated to drive the connecting buffer plate 308 and the tamping plate 310 to compact the ground. At the same time, the pump in the water tank 313 is activated to spray the water in the water tank 313 through the spray nozzle 3131. When the soil adhering to the bottom of the tamping plate 310 is compacted, the lifting hydraulic cylinder 306 is activated to lift the bottom of the tamping plate 310 to the level of the telescopic scraper 3121. The electric telescopic rod 312 is activated to push the telescopic scraper 3121 to scrape away the soil at the bottom of the tamping plate 310. At this time, the compaction of the ground is completed.
