Description

Technical Field

[0001] This invention relates to the field of road construction equipment, and more particularly to a highway concrete paving device with automatic leveling function. Background Technology

[0002] During highway construction, concrete needs to be evenly laid on the road base. However, traditional highway concrete paving equipment has a single function, only capable of laying basic concrete. Subsequent leveling equipment is required to smooth the surface of the laid concrete. If drainage is needed and a slope is required, specialized equipment is needed to adjust the slope angle a second time. This segmented "lay-level-slope adjustment" operation mode not only increases equipment investment and labor costs but also leads to low overall construction efficiency due to waiting between different processes, making it difficult to meet the dual requirements of modern highway construction for both schedule and quality.

[0003] To address this issue, an integrated highway concrete paving device was designed. This device must simultaneously possess automatic material feeding, tilting or parallel scraping adjustment, and automatic compaction functions. After the concrete feeding is completed, it can directly and synchronously complete the slope angle adjustment or parallel scraping operation according to construction needs, and immediately connect to the compaction process to achieve integrated operation, thereby significantly shortening the construction cycle and improving the efficiency and quality stability of road construction. Summary of the Invention

[0004] The purpose of this invention is to provide a highway concrete paving device with automatic leveling function. Through an adjustable paving mechanism, it can flexibly switch between parallel and inclined paving modes. Combined with an adjustable compaction function that can accurately correspond to the paving state, it improves the practicality of the equipment.

[0005] The technical implementation scheme of the present invention is as follows:

[0006] A highway concrete paving device with automatic leveling function includes a frame, a material guiding mechanism, and an inclined leveling mechanism. The frame is a rectangular frame structure, with the material guiding mechanism on the upper part of the frame and the inclined leveling mechanism on both sides of the frame. The inclined leveling mechanism includes a lifting support, a material guiding trough, a screw, an electric cylinder, and a first drive motor. The lifting support is connected to a sliding rod and a screw on the lifting support through a sliding hole and a screw hole at one end, respectively. A first sprocket is provided at one end of the screw, and the first sprocket is connected to a second sprocket on the output shaft of the first drive motor through a first transmission chain.

[0007] Preferably, the guide trough is a rectangular cavity structure with openings at both the top and bottom, and one end of the guide trough is movably connected to a pin on the lifting bracket via a first fixing lug; the upper part of the guide trough is movably connected to a second fixing lug on the lifting bracket via an electric push cylinder.

[0008] Preferably, a second drive motor is installed inside the frame, and the output shaft of the second drive motor is connected to the rotating shaft through a second transmission chain, with wheels at both ends of the rotating shaft.

[0009] Preferably, it also includes a flattening mechanism, which includes a receiving bracket, a first wire guide wheel, a second wire guide wheel, a wire rope, a fixed frame, and a pressure roller. The fixed frame is movably connected to the third fixed ears on both sides of the receiving bracket via pins, and the receiving bracket is provided with a pressure roller inside.

[0010] Preferably, the upper part of the receiving bracket is provided with a first wire guide wheel and a second wire guide wheel; one end of the wire rope is fixedly connected to the connecting block on the fixed frame, and the other end of the wire rope is connected to the winding wheel on the output shaft of the third drive motor through the first wire guide wheel and the second wire guide wheel.

[0011] Preferably, the material guiding mechanism includes a support bracket, a material trough, a spiral guide pipe, and a fourth drive motor. The material trough is set on the upper part of the frame through the support bracket, and a spiral guide pipe is set at the bottom of the material trough.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0026] like Figures 1-8As shown, a highway concrete paving device with automatic leveling function includes a frame 1, a material guiding mechanism 3, and an inclined leveling mechanism 4. The frame 1 has a rectangular frame structure, and the material guiding mechanism 3 is provided on the upper part of the frame 1. The inclined leveling mechanism 4 is provided on both sides of the frame 1. The inclined leveling mechanism 4 includes a lifting bracket 401, a material guiding trough 407, a screw 403, an electric pusher cylinder 406, and a first drive motor 408. The lifting bracket 401 is connected to the sliding rod 402 on the lifting bracket 401 through a sliding hole and a screw hole at one end. The screw 403 is connected to the screw 403, and one end of the screw 403 is provided with a first sprocket 411. The first sprocket 411 is connected to the second sprocket 409 on the output shaft of the first drive motor 408 through the first transmission chain 410. The guide trough 407 is a rectangular cavity structure with openings at both the top and bottom. One end of the guide trough 407 is movably connected to the pin on the lifting bracket 401 through the first fixing ear 405. The upper part of the guide trough 407 is movably connected to the second fixing ear 404 on the lifting bracket 401 through the electric push cylinder 406.

[0027] The upper part of the frame 1 is equipped with an inclination sensor, which is used to monitor the real-time inclination status of the entire tilting and leveling mechanism 4. This sensor, together with the first drive motor 408 and the control equipment, forms a closed-loop control, which can accurately adjust the inclination angle of the guide chute 407, thereby adapting to road construction scenarios with different inclination requirements and ensuring the adaptability and accuracy of the leveling operation.

[0028] It should be noted that the upper part of the frame 1 is equipped with a material guiding mechanism 3 and an inclined scraping mechanism 4. The material guiding mechanism 3 is located on the upper part of the frame 1, and the inclined scraping mechanism 4 is located on both sides of the frame 1. The concrete inside is guided into the inclined scraping mechanism 4 through the material guiding mechanism 3 for scraping operation.

[0029] It should be further explained that the lifting bracket 401 is connected to the slide rod 402 and the screw rod 403 on the lifting bracket 401 through the sliding hole and screw hole at one end, respectively. Therefore, under the drive of the screw rod 403, the entire lifting bracket 401 can be lifted and lowered, and the guide trough 407 connected to it can also be lifted and lowered. When not in operation, the entire guide trough 407 can be raised to achieve movement.

[0030] It should be further explained that one end of the guide trough 407 is movably connected to the pin on the lifting bracket 401 through the first fixed ear 405. Therefore, the entire guide trough 407 can achieve cornering under the drive of the electric push cylinder 406. This design can be adapted to different ground construction applications and can realize the inclined laying and scraping of concrete on the ground surface to form an inclined stone paving surface.

[0031] like Figures 1-5As shown, a second drive motor 11 is installed inside the frame 1, and the output shaft of the second drive motor 11 is connected to the rotating shaft 8 through the second transmission chain 10. The two ends of the rotating shaft 8 are provided with walking wheels 7.

[0032] It should be noted that the rotating shaft 8 is mounted on the upper part of the frame 1 through a bearing seat, and the rotating shaft 8 is driven by the second drive motor 11. The entire equipment is moved through the walking wheels 7, and the leveling operation is achieved in conjunction with the tilting and leveling mechanism 4 on its upper part.

[0033] like Figures 1-7 As shown, it also includes a flattening mechanism 5, which includes a receiving bracket 501, a first wire guide wheel 507, a second wire guide wheel 502, a steel wire rope 504, a fixed frame 505, and a pressure roller 506. The fixed frame 505 is movably connected to the third fixed ears on both sides of the receiving bracket 501 through a pin, and the pressure roller 506 is provided inside the receiving bracket 501. The first wire guide wheel 507 and the second wire guide wheel 502 are provided on the upper part of the receiving bracket 501. One end of the steel wire rope 504 is fixedly connected to the connecting block 503 on the fixed frame 505, and the other end of the steel wire rope 504 is connected to the winding wheel on the output shaft of the third drive motor 508 through the first wire guide wheel 507 and the second wire guide wheel 502.

[0034] It should be noted that the flattening mechanism 5 is set up to compact the concrete after it is laid flat. In order to cooperate with the inclined scraping mechanism 4 to achieve inclined compaction, the entire fixed frame 505 is movably connected to the third fixed ears on both sides of the receiving bracket 501 through the pin shaft. The upper part of the fixed frame 505 is connected to the winding wheel on the output shaft of the third drive motor 508 through the wire rope 504. Under the drive of the third drive motor 508, it can be stretched to adjust the angle of the entire fixed frame 505, and then simultaneously lift the pressure roller 506 to match the inclination angle of the concrete for compaction, thereby forming an inclined laying base surface.

[0035] It should be further explained that when adjusting the angle, the third drive motor 508 is controlled to achieve synchronous winding and unwinding of the wire rope, thereby achieving lifting and pressing, which makes it easy to adjust to the tilt angle that matches the construction and laying surface.

[0036] like Figures 1-8As shown, the material guiding mechanism 3 includes a support bracket 301, a material trough 302, a spiral guide tube 304, and a fourth drive motor 303. The material trough 302 is mounted on the upper part of the frame 1 via the support bracket 301, and the spiral guide tube 304 is provided at the bottom of the material trough 302. The fourth drive motor 303 is provided at one end of the spiral guide tube 304. The material trough 302 is a rectangular cavity structure with an open top, and the discharge pipe of the material trough 302 is connected to the connecting hole on the spiral guide tube 304. The discharge end of the spiral guide tube 304 is located on the upper part of the material guiding trough 407.

[0037] It should be noted that the material trough 302 is set on the upper part of the frame 1 through the support bracket 301, and the bottom of the material trough 302 is provided with a discharge port, which is connected to the spiral guide pipe 304. This allows the concrete in the material trough 302 to be spirally guided, so as to achieve uniform discharge of the liquid material and enter the guide trough 407, thereby realizing the automated material guiding and automated scraping.

[0038] It should be further explained that there are two material troughs 302, which can guide the internal concrete into the guide troughs at both ends, and can be selected for use as needed.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
