Description

Technical Field

[0001] This utility model relates to the field of pavement construction technology; specifically, this utility model relates to a vibratory compaction device for thin-section construction of airport pavements. Background Technology

[0002] Because traditional vibratory equipment requires manual operation at each point during concrete pavement construction, it is not only time-consuming but also difficult to meet quality standards. Therefore, high-frequency vibratory devices have gradually entered the engineering field and have been widely used. However, the use of high-frequency vibratory devices in concrete pavement construction is generally for thick pavement construction. Manual operation at each point is inefficient, requires repeated movement of equipment, and is difficult to cover large areas of concrete. Manual operation can easily lead to uneven vibration force, affecting the quality and strength of concrete. It is also labor-intensive, and prolonged hand operation can easily cause worker fatigue. Furthermore, the insertion depth is uncontrollable: the angle and depth of the immersion vibrator depend on experience, which can easily lead to under-vibration or over-vibration.

[0003] High-frequency vibratory compaction devices are generally used for thick pavement construction. However, when compacting thin pavements, the high-frequency vibratory compactor is easily burned out because the construction thickness is less than half of the high-frequency vibratory compactor, which affects the construction progress and increases the construction cost. Existing high-frequency vibratory compactors have shortcomings in terms of vibration angle and width adjustment and vibration depth control. They are also bulky and difficult to adjust flexibly according to different construction needs. Therefore, this application proposes a high-frequency vibratory compaction device for thin airport pavement construction. Utility Model Content

[0004] In view of this, the present invention provides a vibratory compaction device for thin-section construction of airport pavement, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0005] To achieve the aforementioned objectives, this utility model provides a row-type vibratory compaction device for thin-section construction of airport pavement, comprising a main unit, a base, a traveling device, a lifting device, and a vibratory equipment assembly. The main unit is equipped with a control console and is mounted on the base. The traveling device is located at the bottom of the base, and the lifting device is located at the front of the main unit. The vibratory equipment assembly includes multiple insertable vibratory rods, which are installed at an angle on the lifting device.

[0006] Preferably, the front end of the lifting device is provided with an angle adjustment component, which includes a rotating frame and an arc-shaped fixing plate. The rotating frame is rotatably installed at the front end of the lifting device, the insertable vibrator is installed at the bottom of the rotating frame, and the arc-shaped fixing plate is fixedly installed on the lifting device. The center of the arc surface of the arc-shaped fixing plate is consistent with the rotation center of the rotating frame. The arc-shaped fixing plate is provided with a plurality of first positioning holes, and the two sides of the rotating frame are provided with second positioning holes. The first positioning holes and the second positioning holes are compatible with each other.

[0007] Preferably, the rotating frame is provided with an H-shaped fixing frame, a middle horizontal plate is fixedly provided on the H-shaped fixing frame, and a slide that can slide along the length direction of the H-shaped fixing frame is provided between the middle horizontal plate and the bottom of the rotating frame. The top of the insert vibrator is fixedly connected to the slide, and the bottom of the insert vibrator is slidably sleeved on the bottom of the rotating frame.

[0008] Preferably, a telescopic hydraulic cylinder is provided between the middle horizontal plate and the top of the rotating frame, the fixed part of the telescopic hydraulic cylinder is fixedly connected to the rotating frame, and the movable part of the telescopic hydraulic cylinder is fixedly connected to the slide.

[0009] Preferably, the top of the insert vibrator is fixedly connected to a first fixing sleeve, the first fixing sleeve is fixedly connected to the slide, the bottom of the rotating frame is fixedly provided with a second fixing sleeve, and the bottom of the insert vibrator is fitted inside the second fixing sleeve.

[0010] Preferably, the second fixing sleeve has three arc-shaped grooves inside, which are evenly distributed around the circumference of the second fixing sleeve. An arc-shaped plate is slidably disposed in each arc-shaped groove. A straight groove is formed on the side of the arc-shaped groove away from the arc-shaped plate. A pressure plate is disposed in the straight groove. The arc-shaped plate contacts the pressure plate. A spring is disposed between the pressure plate and the inner bottom surface of the straight groove. A groove is formed on the side of the arc-shaped plate facing the rotating sleeve. A rotating sleeve is fitted on the top of the second fixing sleeve. A disc is disposed on the side of the rotating sleeve away from the second fixing sleeve. An insert plate is disposed on the disc. The insert plate passes through the rotating sleeve and is inserted into the groove.

[0011] Preferably, a locking block is provided on the side of the disc facing the first fixing sleeve, and a locking groove is provided on the side of the first fixing sleeve facing the disc, and the locking block can be inserted into the locking groove.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects: 1. By setting up a thin-type construction vibratory device, the uneven vibration force caused by manual operation is avoided, which affects the concrete strength. Long-term hand operation can easily cause worker fatigue. The insertion depth is uncontrollable. The angle and depth of the immersion vibrator depend on experience, which can easily lead to problems of under-vibration or over-vibration.

[0013] 2. Conventional high-frequency vibratory compaction devices are bulky, time-consuming and labor-intensive to adjust, and are not suitable for vibration compaction operations in thin pavement construction. This device, however, can adjust the insertion angle of the immersion vibrator according to the thickness of the thin pavement concrete, thereby adapting to the construction conditions of thin pavement and improving construction efficiency and quality.

[0014] 3. When vibrating thin pavement concrete, the insertion angle of the immersion vibrator can be adjusted, and the vibrator can be inserted axially. This ensures that too much concrete is not brought out during insertion and withdrawal, reducing the porosity and minimizing repairs. At the same time, the concrete brought out by the immersion vibrator can be cleaned when it is withdrawn, completing the self-cleaning operation. Attached Figure Description

Detailed Implementation

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Example 1 like Figure 1 As shown, a vibratory compaction device for thin-section construction of airport pavement includes a main unit 1, a base 2, a traveling device 3, a lifting device 4, and a vibratory equipment group 5. The main unit 1 is equipped with a control console and is mounted on the base 2. The traveling device 3 is located at the bottom of the base 2, and the lifting device 4 is located at the front of the main unit 1. The vibratory equipment group 5 includes multiple insert vibratory rods 6, which are installed at an angle on the lifting device 4.

[0019] In this embodiment, the control console installed on the host 1 is equipped with a centralized control switch button for all equipment. For vibration of thin pavement construction, the operator uses the walking device 3 to make the row-type vibrator move backward along a fixed route, which is highly flexible. Through the lifting device 4, multiple insert vibrators 6 are inserted into the concrete in a lifting manner to continuously vibrate the concrete until the entire concrete pavement is vibrated. The inclination angle of the insert vibrator 6 is different from the conventional almost vertical insertion. Inserting the insert vibrator 6 into the thin pavement concrete at an inclination angle is more suitable for thin pavement construction, increases the vibration area, and improves vibration efficiency and quality.

[0020] Example 2 like Figures 2 to 9As shown, the lifting device 4 is provided with an angle adjustment component at its front end. The angle adjustment component includes a rotating frame 7 and an arc-shaped fixing plate 8. The rotating frame 7 is rotatably installed at the front end of the lifting device 4. An insert vibrating rod 6 is installed at the bottom of the rotating frame 7. The arc-shaped fixing plate 8 is fixedly installed on the lifting device 4. The center of the arc surface of the arc-shaped fixing plate 8 is consistent with the rotation center of the rotating frame 7. Multiple first positioning holes 9 are provided on the arc-shaped fixing plate 8. Second positioning holes 10 are provided on both sides of the rotating frame 7. The first positioning holes 9 and the second positioning holes 10 are compatible with each other.

[0021] A mounting base 11 is fixedly installed at the front end of the lifting device 4. A motor is fixedly installed on the mounting base 11. The output shaft of the motor is fixedly connected to the rotating frame 7. The rotation of the motor adjusts the tilt angle of the rotating frame 7. The tilt angle of the insert vibrator 6 installed at the bottom of the rotating frame 7 is consistent with that of the rotating frame 7. The tilt angle of the insert vibrator 6 is adjusted according to the thickness of the thin pavement concrete. Then, the rotating frame 7 is fixed at the adjusted tilt angle by passing the first positioning hole 9 and the second positioning hole 10 through the pin or bolt. The lifting device 4 can accurately control the insertion depth of the insert vibrator 6.

[0022] The rotating frame 7 is equipped with an H-shaped fixing frame 12, and a middle horizontal plate 12.1 is fixedly installed on the H-shaped fixing frame 12. A slide 13 that can slide along the length of the H-shaped fixing frame 12 is provided between the middle horizontal plate 12.1 and the bottom of the rotating frame 7. The top of the insert vibrator 6 is fixedly connected to the slide 13, and the bottom of the insert vibrator 6 is slidably sleeved on the bottom of the rotating frame 7.

[0023] Furthermore, the H-shaped fixing frame 12 is fixedly connected to the rotating frame 7, and the H-shaped fixing frame 12 and the rotating frame 7 have the same tilt angle. The immersion vibrator 6 has the same tilt angle as the H-shaped fixing frame 12. The sliding direction of the slide 13 is consistent with the axis of the immersion vibrator 6. The immersion vibrator 6 can maintain its tilt angle and be inserted into the concrete along the axis. Unlike the conventional swing insertion and withdrawal, the axial tilt insertion can reduce the porosity. Vertical insertion is more likely to leave holes, and oblique withdrawal can be naturally backfilled, reducing the need for repairs. Conventional swing withdrawal will bring out more concrete, while oblique withdrawal reduces the amount of concrete brought out, which is more advantageous for thin pavement construction.

[0024] A telescopic cylinder 14 is provided between the middle horizontal plate 12.1 and the top of the rotating frame 7. The fixed part of the telescopic cylinder 14 is fixedly connected to the rotating frame 7, and the movable part of the telescopic cylinder 14 is fixedly connected to the slide 13.

[0025] In a relatively specific embodiment, the fixed part of the telescopic cylinder 14 is fixedly connected to the rotating frame 7, the telescopic cylinder 14 and the rotating frame 7 are tilted at the same angle, the movable part of the telescopic cylinder 14 is fixedly connected to the slide 13, the movable part of the telescopic cylinder 14 can stably push the slide 13 to slide along the length direction of the rotating frame 7, and the slide 13 drives the vibrator 6 to axially pass through the bottom of the rotating frame 7 and insert into the thin pavement concrete.

[0026] The top of the insert vibrator 6 is fixedly connected to a first fixing sleeve 15, which is fixedly connected to the slide 13. The bottom of the rotating frame 7 is fixedly provided with a second fixing sleeve 16, and the bottom of the insert vibrator 6 is fitted inside the second fixing sleeve 16.

[0027] Furthermore, the telescopic cylinder 14 can drive the immersion vibrator 6 to pass through the second fixed sleeve 16 axially into the concrete via the first fixed sleeve 15. After vibration is completed, when it is pulled out, the second fixed sleeve 16 fits against the surface of the immersion vibrator 6. When the immersion vibrator 6 is pulled out, the residual concrete can be scraped off by the second fixed sleeve 16 along the circumferential surface of the immersion vibrator 6, thus cleaning the immersion vibrator 6.

[0028] The second fixing sleeve 16 has three arc-shaped grooves 17 inside, which are evenly distributed around the circumference of the second fixing sleeve 16. An arc-shaped plate 18 is slidably arranged in the arc-shaped groove 17. A straight groove 19 is opened on the side of the arc-shaped groove 17 away from the arc-shaped plate 18. A pressure plate 20 is arranged in the straight groove 19. The arc-shaped plate 18 contacts the pressure plate 20. A spring 21 is arranged between the pressure plate 20 and the inner bottom surface of the straight groove 19. A groove 22 is opened on the side of the arc-shaped plate 18 facing the rotating sleeve 23. The rotating sleeve 23 is fitted on the top of the second fixing sleeve 16. A disc 24 is arranged on the side of the rotating sleeve 23 away from the second fixing sleeve 16. An insert plate 25 is arranged on the disc 24. The insert plate 25 passes through the rotating sleeve 23 and is inserted into the groove 22.

[0029] Furthermore, a limiting groove 26 is provided inside the rotating sleeve 23, and a limiting block 27 is provided on the insert plate 25. The limiting block 27 slides in the limiting groove 26. When the first fixed sleeve 15 is displaced to contact the disc 24, the disc 24 is driven by the first fixed sleeve 15. One of the contact surfaces of the groove 22 and the insert plate 25 is an inclined surface, and the other contact surface is a straight surface. The insert plate 25 squeezes the groove 22 through the inclined surface, so that the arc plate 18 slides along the arc surface of the arc groove 17. The arc center of the arc groove 17 is consistent with the center of the second fixed sleeve 16. The arc plate 18 rotates toward the pressure plate 20. The contact surface between the pressure plate 20 and the arc plate 18 is an inclined surface. The pressure plate 20 is driven by the arc plate 18 to move downward in the straight groove 19 to compress the spring 21. A buffer pad is provided between the first fixed plate and the disc 24. The buffer pad and the spring 21 on the first fixed sleeve 15 can provide buffering force.

[0030] A locking block 28 is provided on the side of the disc 24 facing the first fixing sleeve 15, and a locking groove 29 is provided on the side of the first fixing sleeve 15 facing the disc 24, so that the locking block 28 can be inserted into the locking groove 29.

[0031] Furthermore, when the first fixed sleeve 15 contacts the disc 24, the locking block 28 is inserted into the corresponding slot 29. The first fixed sleeve 15 drives the disc 24 to move axially along the rotating sleeve 23. During the axial displacement of the disc 24, when the arc plate 18 slides along the arc surface of the arc groove 17, the other contact surface between the groove 22 and the insert plate 25 is a straight surface. The arc plate 18 drives the insert plate 25 to rotate along the circumferential direction of the second fixed sleeve. The disc 24 rotates with the insert plate 25, and the locking block 28 rotates with the disc 24. The locking block 28 rotates in the slot 29, so that the insertion end of the locking block 28 rotates to the recessed part inside the slot 29, so that the locking block 28 cannot be pulled out from the slot 29 along the axial direction of the first fixed sleeve 15. The first fixed sleeve 15 is limited by the locking block 28 in the axial direction.

[0032] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
