Description

Technical Field

[0001] The invention relates to the field of airport runway engineering construction, and in particular to an automatic battening device and a construction method for airport pavement pads. Background Art

[0002] In airport runway projects, cement concrete pavement is used in the vast majority, which has the characteristics of good durability, high strength, long service life and high integrity. During construction, in order to improve the durability of concrete pavement, the pavement is usually cut into blocks, and silicone or polysulfide sealant is poured into the cut joints for caulking. Before pouring the caulking material, the board joints are usually cleaned and then a pad with a diameter of not less than 10mm is embedded as an isolation and sealing material. The pad can be made of foam plastic or other materials that meet the performance requirements. For specific requirements, see the relevant provisions of 7.1 joint design in the "Civil Airport Cement Concrete Pavement Design Specification (MH / T 5004-2010)".

[0003] The battening device commonly used in the current pad construction can be found in CN202220876826.4, which improves the construction efficiency to a certain extent. However, during long-term use, the following problems are still found: 1. During the construction process, one worker first arranges the foam pad in the seam of the pavement panel, and then another worker uses the battening device to press the foam pad into the seam. At least two workers are required for one work surface. 2. According to the above construction method, since there is a time interval between the two processes of arranging the pad and inserting the pad into the seam and pressing it, during this time interval, there may be risks such as strong winds and unrelated personnel stepping on it, which may lead to the need to rearrange the pad, reducing construction efficiency.

[0004] To this end, the present invention proposes an automatic battening device and a construction method for airport pavement pads to solve the above problems. Summary of the invention

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1 As shown, the present embodiment discloses an automatic pressing device for airport pavement pads, including a vehicle-mounted frame 1, a reeling device 6 is provided on the vehicle-mounted frame 1, a moving device 2 is provided on the rear side of the vehicle-mounted frame 1, a pad pressing assembly 3 is provided on the front side of the vehicle-mounted frame 1, and a pad 7 wound on the reeling device 6 is rolled into the pavement panel seam 9 by the pad pressing assembly 3.

[0031] like Figure 2 As shown, the mobile device 2 includes wheels 2-2, which are arranged on both sides of the vehicle frame 1. The wheels 2-2 are connected to the motor 2-1, which is arranged on the vehicle frame 1. The vehicle frame 1 can be driven to move by starting the motor 2-1.

[0032] like Figures 2 to 4 As shown, the vehicle frame 1 includes a base plate 1-1, on which a hand-held rod 1-3 is arranged. A moving device 2 is arranged at the rear side of the base plate 1-1, and a connecting forearm 1-2 is arranged at the front side of the base plate 1-1, and the connecting forearm 1-2 is rotatably connected to the pad pressing assembly 3.

[0033] The pad strip pressing assembly 3 includes a roller 3-1, which is rotatably connected to the connecting forearm 1-2, a wheel piece 3-2 is fixedly connected to the middle of the drum wall of the roller 3-1, the wheel rim of the wheel piece 3-2 is a concave structure, a pad strip 7 is arranged on the wheel rim of the wheel piece 3-2, one end of the pad strip 7 is laid on the wheel rim of the wheel piece 3-2, and the other end of the pad strip 7 is wound and rolled on the unwinding device 6. The wheel piece 3-2 with a concave structure is based on the principle that 1 / 3 to 1 / 2 of the pad strip 7 can be embedded. The design of the concave structure ensures that the pad strip 7 is not easy to fall out when the wheel piece 3-2 rotates, and the quality of the pad strip 7 is not affected due to the small embedded part.

[0034] The unwinding device 6 includes a pad strip reel 6-1, on which the pad strip 7 is wound and reeled, and the pad strip reel 6-1 is rotatably connected to a reel support 6-2, and the reel support 6-2 is fixedly connected to the bottom plate 1-1. When the wheel 3-2 rolls, the wheel 3-2 presses the pad strip 7 and then rolls forward, so that the pad strip 7 can be continuously drawn out from the pad strip reel 6-1, thereby ensuring the continuity of the construction action.

[0035] The unwinding device 6 also includes a fixed pulley 6-3, which is fixedly connected to the bottom plate 1-1, and is located between the pad strip winding drum 6-1 and the drum 3-1, and the fixed pulley 6-3 is in contact with the pad strip 7. The fixed pulley 6-3 is used to prop up the pad strip 7 suspended between the pad strip winding drum 6-1 and the drum 3-1, thereby ensuring the straightness of the pad strip 7 and preventing the pad strip 7 from shaking and coming off the wheel 3-2.

[0036] The vehicle-mounted frame 1 is also provided with a vibration compaction assembly 4, which includes a counterweight 4-1 and a vibrator 4-2, and the counterweight 4-1 and the vibrator 4-2 are both fixedly connected to the front end of the bottom plate 1-1. The vibrator 4-2 can generate high-frequency vibrations, and the vibrator 4-2 drives the bottom plate 1-1 to vibrate during the vibration process, thereby driving the roller 3-1 and the wheel 3-2 to vibrate and compact the inserted pad 7 up and down, thereby assisting in compacting the pad 7. It should be noted that, since the diameter of the pad 7 is usually slightly larger than the road panel seam 9, and the pad 7 is a flexible material, it is usually necessary to use a tool to compact the pad 7 after manual insertion to prevent the pad 7 from not being inserted into the bottom and failing to meet the construction requirements. The present invention drives the roller 3-1 and the wheel 3-2 to vibrate and compact the pad 7 through the vibrator 4-2, thereby effectively improving the work efficiency.

[0037] The counterweight block 4-1 adds weight to the bottom plate 1-1 to ensure that the roller 3-1 and the wheel piece 3-2 can press the pad 7 into the road panel seam 9. At the same time, the vehicle-mounted frame 1 with the added counterweight can better keep the wheel piece 3-2 in the road panel seam 9 and not easily jump out of the gap during the travel process. In addition, the vehicle-mounted frame 1 with the added counterweight can also keep the vehicle-mounted frame 1 stable and reduce shaking when the vibrator 4-2 is working. The weight of the counterweight block 4-1 and the vibration power of the vibrator 4-2 can be freely selected and set according to the test construction situation.

[0038] A guide assembly 5 is provided on one side of the vehicle frame 1. The guide assembly 5 includes a connecting rod 5-1. One end of the connecting rod 5-1 is fixedly connected to the bottom plate 1-1. The other end of the connecting rod 5-1 is rotatably connected to a guide pulley 5-2. The guide pulley 5-2 is slidably connected and matched with the guide rail 5-3. A height-adjustable guide rail support 5-4 is provided below the guide rail 5-3. The guide rail 5-3 is arranged parallel to the road panel seam 9. The guide pulley 5-2 slides on the guide rail 5-3 to ensure that the wheel 3-2 always moves along a straight line in the road panel seam 9 and will not jump out easily, thereby avoiding the risk of the roller 3-1 or the wheel 3-2 jumping out of the direction of the road panel seam 9 when encountering an obstacle. As a way to achieve the height adjustment of the guide rail support 5-4, a plurality of threaded bolts can be provided at the bottom of the guide rail support 5-4, and the height of the guide rail support 5-4 can be adjusted by screwing the bolts.

[0039] As a method of arranging the guide rail 5-3 in parallel with the road panel seam 9, before construction, a parallel line matching the distance of the device can be drawn along the road panel seam 9, and the guide rail 5-3 can be placed on the parallel line. To improve construction efficiency, more than two guide rails 5-3 can be arranged end to end. When the vehicle-mounted frame 1 moves to the end of the guide rail 5-3, the guide rail 5-3 before this section of the guide rail 5-3 can be moved to the end of this section of the guide rail 5-3 for splicing to ensure that the vehicle-mounted frame 1 can move and work continuously.

[0040] It should be additionally explained that, in some cases, the guide assembly 5 may not be required.

[0041] An automatic layering construction method for airport pavement pads, the steps of which are:

[0042] Step 1: Prepare the device. Arrange the device on the concrete pavement 8. The wheels 2-2 are located on both sides of the road slab seam 9. The roller 3-1 and the wheel piece 3-2 are located in front of the traveling direction. The wheel piece 3-2 is placed in the road slab seam 9. The roller 3-1 straddles the road slab seam 9.

[0043] Step 2: Guide rail arrangement: place the guide rail 5-3 parallel to the road panel seam 9, and adjust the distance from the road panel seam 9 to match the vehicle frame 1. Adjust the height of the guide rail 5-3 through the guide rail support 5-4 to ensure that it matches the height of the vehicle frame 1. Place the guide pulley 5-2 in the slide groove of the guide rail 5-3, and place the guide pulley 5-2 connected to the vehicle frame 1 through the connecting rod 5-1 at the starting end of the guide rail 5-3;

[0044] Step 3: Place the pad strip. Wrap the pad strip 7 around the pad strip take-up drum 6-1 and ensure that it can be pulled out smoothly. Pull one end of the pad strip 7 out from the pad strip take-up drum 6-1, pass through the fixed pulley 6-3, wrap it around the wheel 3-2, and pull it to the road slab seam 9 at the bottom of the wheel 3-2;

[0045] Step 4: The vehicle is driven. The motor 2-1 is started. The vehicle frame 1 moves forward through the wheels 2-2 and the rollers 3-1. At the same time, the hand-held rod 1-3 can be supported to assist in maintaining overall stability.

[0046] Step 5: The pad strip is pressed, and the pad strip 7 is pressed into the road panel seam 9 by the wheel piece 3-2 as the roller 3-1 rolls, and the vibrator 4-2 is started, and the vibrator 4-2 vibrates, and the pad strip 7 is pressed downward by vibration to meet the required construction depth. The weight of the counterweight block 4-1 and the vibration power of the vibrator 4-2 can be freely selected according to the test construction situation.

[0047] The automatic layering device and construction method for airport pavement pads provided by the present invention have the following advantages:

[0048] 1. Automated construction. In the original construction process, one worker was required to place the pad strip 7 in the road slab seam 9, and then another worker used a pressure strip device to insert the pad strip 7 into the seam and compact it with tools. At least two workers were required for one working surface. This device can realize mechanized and automated continuous construction, reduce the use of labor, and reduce the intensity of labor operations.

[0049] 2. Improve construction efficiency. In the original construction method, there is a time interval between the two processes of arranging the pad strips 7 and inserting the pad strips 7 into the seams and pressing them. During this time interval, there may be accidents such as strong winds and trampling by unrelated personnel, which may cause construction to be disturbed or even require the rearrangement of the pad strips 7, greatly affecting the construction efficiency. This device performs the two processes of arranging the pad strips 7 and inserting them into the seams and pressing them in the original construction method at the same time, avoiding related risks.

[0050] 3. Avoid affecting the construction quality. According to the above construction method, after the cushion strips 7 are arranged, the cushion strips are inserted into the seams and pressed, and the cushion strips 7 are at risk of being contaminated or damaged, which affects the quality. This device avoids the related risks.

[0051] Fourth, avoid affecting the safety of airport operations. In airport construction, ensuring the safety of airport operations is of paramount importance. The present invention avoids the risk of the pad strips 7 being blown into the airport operation area by the wind during the time interval between the two processes of arranging the pad strips 7 and inserting the pad strips 7 into the seams and pressing them, and will not affect the normal operation of the airport.

[0052] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
