Description

Technical Field

[0001] This invention relates to the field of road construction technology, specifically to a vibratory compaction device and its operating method for road construction. Background Technology

[0002] Roller-compacted concrete pavement is a new type of concrete pavement that uses the main construction machinery for asphalt concrete pavement. Through the combined action of strong vibration and rolling, ultra-dry hard cement concrete with zero slump is spread and compacted. Compared with traditional road concrete, this type of concrete pavement has the advantages of high strength, stability and durability, as well as the characteristics of convenient construction and early opening to traffic. It also has the advantages of saving a lot of cement and significant economic benefits.

[0003] According to the patent titled "A Road Surface Compaction Device for Highway Construction" (patent publication number: CN212270599U, patent publication date: 2021-01-01), the device includes a base. Two support plates are fixedly installed on both the front and rear sides of the bottom of the base. A common rotating shaft is rotatably installed between the two support plates on the same side. A compaction roller is fixedly installed on each of the two rotating shafts. Two vertical plates are fixedly installed on the top of the base. A common horizontal plate is fixedly installed on the side of the two vertical plates that are close to each other. An installation hole is opened on the front side of the horizontal plate, and a connecting shaft is rotatably installed in the installation hole. This utility model has a reasonable structural design. It increases the downward pressure of the compaction roller by driving the vibrating plate to reciprocate, and it ensures the road quality by driving the nozzle to swing and spray the road evenly. It has high reliability.

[0004] Based on the aforementioned existing technology, the current vibratory compaction devices and operating methods for road construction still have the following problems: Although existing vibratory compaction devices for road construction use rectangular vibratory compaction plates, the compaction of the road surface is often unsatisfactory. In addition, due to the uneven compaction effect, the road surface often becomes uneven, which not only affects the overall quality of the road surface, but may also cause the vibratory compaction device to be hit during operation, thereby increasing the risk of device damage. Therefore, the present invention provides a vibratory compaction device and operating method for road construction. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a vibratory compaction device and operating method for road construction, solving the following problems that existing vibratory compaction devices and operating methods for road construction still have: Although existing vibratory compaction devices for road construction use rectangular vibratory compaction plates, the compaction of the road surface is often unsatisfactory. In addition, due to the uneven compaction effect, the road surface often becomes uneven, which not only affects the overall quality of the road surface, but may also cause the vibratory compaction device to be hit during operation, thereby increasing the risk of damage to the device.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a vibratory compaction device for road construction, comprising a drive vehicle, a lifting mechanism provided on the left side of the drive vehicle, a protective mechanism provided at the bottom of the lifting mechanism, a rotating mechanism provided at the bottom of the lifting mechanism, and a vibratory compaction mechanism provided at the bottom of the rotating mechanism, the vibratory compaction mechanism comprising a compaction component, a kinetic energy component, and a vibration component;

[0007] A compaction assembly, located at the bottom of the rotating mechanism, includes a compaction box;

[0008] The kinetic energy component, located on top of the compaction assembly, includes a mounting block, a reciprocating slide column, a linkage rod, a motor frame, and a second motor. The mounting block is fixedly installed inside a circular hole at the top of the compaction box. Several spring holes are provided at the bottom of the mounting block. A reciprocating slide column is movably installed through the middle of the mounting block. A linkage rod is movably connected to the top of the reciprocating slide column. A motor frame is fixedly installed on the top of the mounting block. A second motor is fixedly installed on the top of the motor frame. A turntable is fixedly installed at one end of the output shaft of the second motor.

[0009] A vibration assembly is installed inside the compaction assembly and is used to generate vibration in conjunction with the kinetic energy assembly. The vibration assembly includes a return spring, a spring connecting tube, and a vibration disc. The top end of the return spring is fixedly installed inside the spring hole, and the bottom end of the return spring is fixedly installed at the bottom of the inner cavity of the spring connecting tube. The vibration disc is fixedly installed at the bottom of the spring connecting tube. The reciprocating slide column 523 can move up and down. While the reciprocating slide column 523 moves, it drives the spring connecting tube 532 to move synchronously inside the compaction box 511. The bottom of the vibration disc 531 continuously impacts the bottom of the inner cavity of the compaction box 511, thereby causing the compaction box 511 to vibrate and compact the road surface.

[0010] The lifting mechanism includes a mounting frame, a hydraulic cylinder, and a mounting frame. The mounting frame is fixedly installed on the left side of the driving vehicle. A hydraulic cylinder is fixedly installed above the top plate of the mounting frame. The output rod of the hydraulic cylinder passes through the top of the mounting frame and is fixedly connected to the mounting frame.

[0011] The protective mechanism includes a triangular frame, connecting rods, and a protective ring. The triangular frame is fixedly fitted on the outside of the hydraulic cylinder output rod. Connecting rods are fixedly installed at the bottom of one end of the three connecting rods on the outer ring of the triangular frame, and protective rings are fixedly installed at the bottom of the connecting rods.

[0012] The rotating mechanism includes a first motor, a motor shaft, and a rotating frame. The first motor is fixedly installed at the bottom of the inner cavity of the mounting frame. The output end of the first motor is rotatably mounted with a motor shaft. The bottom end of the motor shaft movably passes through the bottom plate of the mounting frame and is fixedly connected to the rotating frame. When the first motor 41 runs, it drives the rotating frame 43 to rotate through the motor shaft 42. The rotation of the rotating frame 43 synchronously drives the crushing box 511 to rotate.

[0013] Preferably, the compaction assembly further includes a compaction arc plate fixedly installed at the bottom of the outer ring of the compaction box.

[0014] Preferably, one edge of the turntable is movably connected to the top of the linkage rod via a connecting post.

[0015] This invention also discloses an operation method for a vibratory compaction device in road construction, comprising the following steps:

[0016] S1: First, the device is moved to the designated location by driving a vehicle according to the location of use. Then, the hydraulic cylinder is operated, and the output rod drives the mounting frame to move up and down. The up and down movement of the mounting frame drives the protective mechanism, the rotating mechanism and the vibratory compaction mechanism to move up and down simultaneously, so that the vibratory compaction mechanism contacts the ground.

[0017] S2: Then the bottom of the compaction box contacts the ground. At this time, the second motor runs and drives the turntable to rotate. The rotation of the turntable drives the top of the linkage rod to move in a circular motion. Then the turntable is connected to the top of the reciprocating slide column through the linkage rod, thereby driving the reciprocating slide column to move up and down. While the reciprocating slide column moves, it drives the spring connecting tube to move synchronously inside the compaction box. The bottom of the vibrating plate continuously hits the bottom of the compaction box cavity, thereby causing the compaction box to vibrate and compact the road surface.

[0018] S3: While the vibratory compaction mechanism is running, the first motor is running, which drives the rotating frame to rotate through the motor shaft. The rotation of the rotating frame synchronously drives the compaction box to rotate. When the compaction box rotates, it performs rotational vibration compaction on the road surface.

[0019] This invention provides a vibratory compaction device and its operating method for road construction. Compared with the prior art, it has the following advantages:

[0020] (1) The vibration compaction device and operation method for road construction: while the vibration compaction mechanism is running, the first motor is running, which drives the rotating frame to rotate through the motor shaft. The rotating frame rotates synchronously and drives the compaction box to rotate. When the compaction box rotates, it performs rotational vibration compaction on the road surface, which can drastically reduce the internal friction between soil particles, make the particles closer together, increase the density, and thus achieve the purpose of compaction.

[0021] (2) The vibratory compaction device and operation method for road construction, through the compaction box, the outer ring is close to the bottom of the compaction arc plate, and the compaction arc plate is arc-shaped. Thus, when the device moves, the compaction arc plate with the arc edge can better adapt to the uneven parts of the road surface, such as potholes and protrusions. During the compaction process, the arc edge can transition more smoothly, reducing the impact on the equipment and improving the service life of the equipment.

[0022] (3) The vibratory compaction device and operation method for road construction, through the protective mechanism fitted on the outer ring of the vibratory compaction mechanism, can prevent operators from being injured due to accidental contact with the rotating and vibrating compaction arc plate, thereby reducing work risks and enhancing the safety of the working environment.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-9 The present invention provides a technical solution:

[0035] A vibratory compaction device for road construction includes a drive vehicle 1, a lifting mechanism 2 is provided on the left side of the drive vehicle 1, a protective mechanism 3 is provided at the bottom of the lifting mechanism 2, a rotating mechanism 4 is provided at the bottom of the lifting mechanism 2, and a vibratory compaction mechanism 5 is provided at the bottom of the rotating mechanism 4. The vibratory compaction mechanism 5 includes a compaction component 51, a kinetic energy component 52, and a vibration component 53.

[0036] The compaction assembly 51 is located at the bottom of the rotating mechanism 4 and includes a compaction box 511;

[0037] The kinetic energy component 52 is located on top of the compaction component 51 and includes a mounting block 521, a reciprocating slide column 523, a linkage rod 524, a motor frame 525, and a second motor 526. The mounting block 521 is fixedly installed inside the round hole at the top of the compaction box 511. Several spring holes 522 are opened at the bottom of the mounting block 521. The reciprocating slide column 523 is movably installed through the middle of the mounting block 521. The linkage rod 524 is movably connected to the top of the reciprocating slide column 523. The motor frame 525 is fixedly installed on the top of the mounting block 521. The second motor 526 is fixedly installed on the top of the motor frame 525. A turntable 527 is fixedly installed at one end of the output shaft of the second motor 526.

[0038] Vibration component 53 is disposed inside the compaction component 51 and is used to generate vibration in conjunction with the kinetic energy component 52. Vibration component 53 includes a return spring 533, a spring connecting tube 532 and a vibrating disc 531. The top end of the return spring 533 is fixedly installed inside the spring hole 522, and the bottom end of the return spring 533 is fixedly installed at the bottom of the inner cavity of the spring connecting tube 532. The vibrating disc 531 is fixedly installed at the bottom of the spring connecting tube 532. The reciprocating slide column 523 can move up and down. While the reciprocating slide column 523 moves, it drives the spring connecting tube 532 to move synchronously inside the compaction box 511. The bottom of the vibrating disc 531 continuously impacts the bottom of the inner cavity of the compaction box 511, thereby causing the compaction box 511 to vibrate and compact the road surface.

[0039] The top end of the return spring 533 is fixedly installed at the bottom of the inner cavity of the spring hole 522, and the bottom end of the return spring 533 is fixedly connected to the top of the vibrating plate 531 through the spring connecting tube 532. Each return spring 533 has a spring connecting tube 532 installed at its bottom. Thus, when the vibrating plate 531 is driven up and down by the reciprocating slide column 523, the return spring 533 plays a buffering role for the vibrating plate 531.

[0040] The lifting mechanism 2 includes a mounting frame 21, a hydraulic cylinder 22, and a mounting frame 23. The mounting frame 21 is fixedly installed on the left side of the driving vehicle 1. The hydraulic cylinder 22 is fixedly installed above the top plate of the mounting frame 21. The output rod of the hydraulic cylinder 22 passes through the top of the mounting frame 21 and is fixedly connected to the mounting frame 23.

[0041] The hydraulic cylinder 22 is model YHG1. When the hydraulic cylinder 22 is running, it drives the mounting frame 23 to move up and down through the output rod. The up and down movement of the mounting frame 23 synchronously drives the protective mechanism 3, the rotating mechanism 4 and the vibratory compaction mechanism 5 to move up and down, so that the vibratory compaction mechanism 5 contacts the ground, thereby realizing the lifting and lowering of the protective mechanism 3, the rotating mechanism 4 and the vibratory compaction mechanism 5.

[0042] The protective mechanism 3 includes a triangular frame 31, a connecting rod 32, and a protective ring 33. The triangular frame 31 is fixedly mounted on the outside of the output rod of the hydraulic cylinder 22. The bottom of one end of each of the three connecting rods on the outer ring of the triangular frame 31 is fixedly mounted with a connecting rod 32, and the bottom of the connecting rod 32 is fixedly mounted with a protective ring 33.

[0043] The outer ring of the vibratory compaction mechanism 5 is fitted with a protective mechanism 3, which can prevent operators from being injured by accidental contact with the rotating and vibrating compaction arc plate 512, thereby reducing work risks and enhancing the safety of the working environment.

[0044] The rotating mechanism 4 includes a first motor 41, a motor shaft 42, and a rotating frame 43. The first motor 41 is fixedly installed at the bottom of the inner cavity of the mounting frame 23. The output end of the first motor 41 is rotatably mounted with the motor shaft 42. The bottom end of the motor shaft 42 movably passes through the bottom plate of the mounting frame 23 and is fixedly connected to the rotating frame 43. When the first motor 41 runs, it drives the rotating frame 43 to rotate through the motor shaft 42. The rotation of the rotating frame 43 synchronously drives the crushing box 511 to rotate.

[0045] While the vibratory compaction mechanism 5 is running, the first motor 41 is running, which drives the rotating frame 43 to rotate through the motor shaft 42. The rotation of the rotating frame 43 synchronously drives the compaction box 511 to rotate. When the compaction box 511 rotates, it performs rotational vibration compaction on the road surface, which can drastically reduce the internal friction between soil particles, bring the particles closer together, increase the density, and thus achieve the purpose of compaction.

[0046] In this embodiment, the compaction assembly 51 also includes a compaction arc plate 512 fixedly installed at the bottom of the outer ring of the compaction box 511. The compaction arc plate 512 is fixedly installed near the bottom of the outer ring of the compaction box 511, and the compaction arc plate 512 is arc-shaped. Therefore, when the device moves, the compaction arc plate 512 with arc-shaped edges can better adapt to uneven parts of the road surface, such as potholes and bumps. During the compaction process, the arc-shaped edges can transition more smoothly, reducing the impact on the equipment and improving the service life of the equipment.

[0047] In this embodiment, one edge of the turntable 527 is movably connected to the top of the linkage rod 524 via a connecting column. The rotation of the turntable 527 drives the top of the linkage rod 524 to move in a circular motion. Then, the turntable 527 is connected to the top of the reciprocating slide column 523 via the linkage rod 524, thereby realizing the reciprocating slide column 523 moving up and down.

[0048] This invention also discloses an operation method for a vibratory compaction device in road construction, comprising the following steps:

[0049] S1: First, the device is moved to the designated location by driving vehicle 1 according to the location of use. Then, the hydraulic cylinder 22 is operated, and the mounting frame 23 is moved up and down through the output rod. The up and down movement of the mounting frame 23 synchronously drives the protective mechanism 3, the rotating mechanism 4 and the vibratory compaction mechanism 5 to move up and down, so that the vibratory compaction mechanism 5 contacts the ground.

[0050] S2: Then the bottom of the compaction box 511 contacts the ground. At this time, the second motor 526 runs and drives the turntable 527 to rotate. The rotation of the turntable 527 drives the top of the linkage rod 524 to move in a circular motion. Then the turntable 527 is connected to the top of the reciprocating slide column 523 through the linkage rod 524, thereby driving the reciprocating slide column 523 to move up and down. While the reciprocating slide column 523 moves, it drives the spring connecting tube 532 to move synchronously inside the compaction box 511. The bottom of the vibrating plate 531 continuously hits the bottom of the inner cavity of the compaction box 511, thereby causing the compaction box 511 to vibrate and compact the road surface.

[0051] S3: While the vibratory compaction mechanism 5 is running, the first motor 41 is running, which drives the rotating frame 43 to rotate through the motor shaft 42. The rotation of the rotating frame 43 synchronously drives the compaction box 511 to rotate. When the compaction box 511 rotates, it performs rotational vibration compaction on the road surface.
