Description

Technical Field

[0001] This invention relates to the field of road construction equipment technology, and in particular to a concrete curing and covering device for road construction. Background Technology

[0002] During road construction, concrete needs to be kept moist after pouring to prevent excessive evaporation of moisture, which could cause road surface cracking and affect the road's strength and service life. Traditional membrane curing methods rely heavily on manual laying. Workers walking on the edges of freshly poured concrete is not only inefficient but also poses a risk of damaging the finished concrete. Furthermore, the membrane often does not adhere tightly and is easily blown away by the wind.

[0003] Some simple laminating equipment available on the market typically has the following problems:

[0004] 1. The structure is fixed and cannot adapt to road construction of different widths;

[0005] 2. Limited functionality, mostly only able to complete the unwinding action, unable to effectively wet and pre-treat the concrete before coating;

[0006] 3. It is difficult to flexibly adjust the height of the pressure roller according to the unevenness of the concrete surface, resulting in poor curing effect.

[0007] Therefore, this application proposes a highly adaptable, functionally integrated, and flexibly adjustable concrete curing and covering device for road construction. Summary of the Invention

[0008] The present invention aims to solve the problems of poor adaptability, limited functionality, and inability to flexibly adjust the height of the compaction and wetting components according to road conditions in existing road concrete coating equipment.

[0009] To solve the above technical problems, the technical solution provided by the present invention is: a concrete curing and covering device for road construction, including a mounting frame, the mounting frame being an L-shaped frame, and an adjustable membrane tube positioning shaft and an adjustable mounting frame being mounted on the upper part, the adjustable membrane tube positioning shaft being rotatably mounted between the adjustable mounting frame and the upper part of the mounting frame;

[0010] An adjustable water pipe and a pressing roller are installed on one side of the lower part of the mounting frame. The ends of the water pipe and the pressing roller are mounted on the mounting plate. An adjustment component that drives the mounting plate to move up and down is installed on the lower side wall of the mounting frame.

[0011] Multiple sets of spray heads are installed at equal intervals on the lower side of the water pipe, and the ends are connected to water delivery hoses. The outer side of the pressure roller is covered with a protective soft sleeve.

[0012] As an improvement, the adjustable membrane tube positioning shaft includes a base shaft and an extension shaft. The end of the extension shaft is equipped with a plug shaft, and the end of the base shaft is provided with a plug hole for insertion of the plug shaft.

[0013] As an improvement, the adjustable mounting bracket includes a base frame and an extension bend frame. An insert plate is installed at the end of the extension bend frame, and the end of the base frame is provided with a slot for inserting the insert plate. A hand-tightening bolt is installed on the side wall of the slot and connected by threads. The insert plate is provided with multiple sets of positioning holes for inserting the ends of the hand-tightening bolts.

[0014] As an improvement, the ends of the base shaft and the extension shaft that are furthest from each other pass through the mounting bracket and the extension bend, respectively, and are rotatably connected.

[0015] As an improvement, the pressing roller is composed of multiple sets of rollers continuously combined. One end of the pressing roller is a threaded shaft, and the other end is a threaded hole that fits into the threaded shaft. The threaded shaft at the end of the pressing roller is rotatably connected to the mounting plate.

[0016] As an improvement, the adjustment assembly includes a lead screw and a moving block. A mounting frame is fixedly installed on the lower outer side of the mounting bracket. The lead screw is rotatably installed inside the mounting frame. The top of the lead screw protrudes through the top plate of the mounting frame and is equipped with a handwheel. The moving block is sleeved on the outside of the lead screw and connected by threads. The lower part of the mounting bracket is provided with a slide rail that fits and moves up and down with the moving block. The moving block is fixedly connected to the mounting plate.

[0017] As an improvement, a reinforcing support frame is connected between the two side walls of the mounting frame. A mounting seat is provided in the middle of the reinforcing support frame. A support shaft for supporting the membrane is rotatably mounted on one side of the mounting seat, so that the membrane is supported above the water pipe.

[0018] As an improvement, the support shaft is composed of multiple sets of horizontal shafts in continuous combination. One end of the support shaft is a threaded shaft, and the other end is a threaded hole that fits into the threaded shaft.

[0019] As an improvement, a positioning frame for connecting to the traveling equipment is installed on the upper side of the mounting bracket.

[0020] With the above structure, the present invention has the following advantages:

[0021] 1. High adaptability and convenient adjustment: Through the coordinated design of the adjustable membrane roll positioning shaft and the adjustable mounting frame, membrane rolls of different lengths can be installed quickly, thereby adapting to the construction needs of roads of different widths. This multi-purpose design improves the versatility of the equipment.

[0022] 2. Integrates wetting and film covering into one, with integrated functions: An adjustable water pipe and spray head are installed in front of the pressing roller, which can pre-spray and wet the dry concrete base surface before film covering, creating a better curing environment. The two processes are combined into one, significantly improving construction efficiency.

[0023] 3. Tight and high-quality film adhesion: The height of the pressing rollers can be precisely controlled by adjusting the components, so that the film is always pressed tightly against the concrete surface with appropriate pressure. With the help of the protective soft sleeve to avoid damage to the film, the film is guaranteed to be free of air bubbles and tightly adhered, effectively improving the curing effect.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] As attached Figure 1 and attached Figure 4 As shown, a concrete curing and covering device for road construction includes a mounting frame 1, which is an L-shaped frame. A positioning frame 17 connected to a traveling device is mounted on the upper side of the mounting frame 1. An adjustable membrane tube positioning shaft 2 and an adjustable mounting frame 3 are mounted on the upper part of the mounting frame 1. The adjustable membrane tube positioning shaft 2 includes a base shaft 21 and an extension shaft 22. An insertion shaft 23 is installed at the end of the extension shaft 22. The end of the base shaft 21 is provided with an insertion hole 24 for inserting the insertion shaft 23. By engaging the insertion shaft 23 with insertion holes 24 of different depths, the overall length of the adjustable membrane tube positioning shaft 2 can be changed, thereby adapting to curing membrane rolls of different widths.

[0034] As attached Figure 5 As shown, the adjustable mounting frame 3 includes a base frame 31 and an extension bend frame 32. An insert plate 33 is installed at the end of the extension bend frame 32. The base frame 31 has a slot 34 at its end for inserting the insert plate 33. A hand-tightening bolt 35 is installed on the side wall of the slot 34 and connected by threads. The insert plate 33 has multiple sets of positioning holes 36 for inserting the ends of the hand-tightening bolts 35. When the length of the adjustable membrane tube positioning shaft 2 changes, the position of the insert plate 33 in the slot 34 is adjusted synchronously, and locked by the cooperation of the hand-tightening bolts 35 with different positioning holes 36, so that the length of the adjustable mounting frame 3 matches that of the adjustable membrane tube positioning shaft 2, providing stable support for the other end of the membrane tube.

[0035] As attached Figure 1 As shown, the base shaft 21 and the extension shaft 22, with their ends facing away from each other, pass through the mounting frame 1 and the extension bending frame 32 respectively, and are rotatably connected. The adjustable film tube positioning shaft 2 is rotatably installed between the adjustable mounting frame 3 and the upper part of the mounting frame 1, so that the film tube can rotate with the front during the unwinding process, reducing tensile resistance and ensuring a smooth coating process.

[0036] As attached Figure 6As shown, an adjustable water pipe 6 and a pressing roller 5 are installed on one side of the lower part of the mounting frame 1. Multiple spray heads 7 are equidistantly installed on the lower side of the water pipe 6, and their ends are connected to a water delivery hose 16. This is used to uniformly spray and moisten the concrete surface before covering with the membrane, improving the curing effect. The pressing roller 5 is composed of multiple rollers continuously combined. One end of the pressing roller 5 is a threaded shaft, and the other end is a threaded hole for threaded insertion. The number of rollers can be flexibly combined according to the road width, and it is convenient to replace individual rollers after wear. The threaded shaft at the end of the pressing roller 5 is rotatably connected to the mounting plate 10. A protective soft sleeve 18 is fitted on the outside of the pressing roller 5 to prevent the hard roller from directly contacting and crushing the membrane, while also increasing the friction with the membrane, making it flatter and more adherent.

[0037] As attached Figure 2 Appendix Figure 6 and attached Figure 7 As shown, the ends of the water pipe 6 and the pressing roller 5 are mounted on the mounting plate 10. An adjustment assembly for moving the mounting plate 10 up and down is installed on the lower side wall of the mounting frame 1. The adjustment assembly includes a lead screw 14 and a moving block 11. A mounting frame 13 is fixedly installed on the lower outer side of the mounting frame 1. The lead screw 14 is rotatably installed inside the mounting frame 13. The top of the lead screw 14 protrudes through the top plate of the mounting frame 13 and is equipped with a handwheel 15. The moving block 11 is sleeved on the outside of the lead screw 14 and connected by threads. The lower part of the mounting frame 1 is provided with a slide rail 12 that fits the moving block 11 and moves up and down. The moving block 11 is fixedly connected to the mounting plate 10. By rotating the handwheel 15 to drive the lead screw 14, the moving block 11 can be precisely controlled to drive the mounting plate 10 and the water pipe 6 and pressing roller 5 installed on it to move up and down synchronously, so as to adapt to the road surface with different flatness and adjust the spraying height and pressing force.

[0038] As attached Figure 1 and attached Figure 3 As shown, a reinforcing support frame 8 is connected between the two side walls of the mounting frame 1. A mounting base 9 is located in the middle of the reinforcing support frame 8. A support shaft 4 for supporting the membrane is rotatably mounted on one side of the mounting base 9, allowing the membrane to be supported above the water pipe 6. This support shaft 4 supports the membrane released from the membrane tube, preventing it from sagging and contacting the water pipe 6, causing contamination or tearing, and guides the membrane to cover the pressure roller 5 at a suitable angle. The support shaft 4 is composed of multiple sets of horizontal shafts continuously combined. One end of the support shaft 4 is a threaded shaft, and the other end is a threaded hole for threaded insertion, facilitating assembly and individual replacement according to the equipment width.

[0039] The specific usage method is as follows:

[0040] Before construction, first adjust the length of the adjustable membrane tube positioning shaft 2 according to the width of the road surface to be constructed. Specifically, insert the insertion shaft 23 of the extension shaft 22 into the insertion hole 24 of the base shaft 21 to the appropriate length; at this time, the adjustable mounting frame 3 will also be moved accordingly. Then, loosen the hand-tightening bolt 35, slide the insertion plate 33 of the extension bending frame 32 into the slot 34 of the base frame 31, adjust it to match the position of the extension shaft 22, and then tighten the hand-tightening bolt 35 into the corresponding positioning hole 36. At this point, place the center hole of the entire roll of curing membrane onto the adjusted adjustable membrane tube positioning shaft 2, and rotate both ends of the adjustable membrane tube positioning shaft 2 between the mounting frame 1 and the extension bending frame 32.

[0041] Adjust the height of the water pipe 6 and the pressing roller 5 according to the dryness and flatness of the concrete surface. Turn the handwheel 15 to drive the screw 14 to rotate, which will drive the moving block 11 connected to it to move up and down along the slide 12. The moving block 11 will drive the mounting plate 10 and the water pipe 6 and pressing roller 5 on it to rise and fall synchronously until the sprinkler head 7 is at a suitable height from the ground and the pressing roller 5 can make good contact with the ground.

[0042] Connect the water delivery hose 16 to the mobile water source on the traveling equipment, and mount the entire device to a tractor or other traveling equipment via the positioning frame 17. At the start of operation, the traveling equipment moves the device forward, and the curing membrane is pulled out from the adjustable membrane cylinder positioning shaft 2. First, water is evenly sprayed onto the concrete surface through the spray nozzles 7 to moisten it. Then, the moistened concrete surface is covered with the curing membrane. Next, the pressing rollers 5 at the rear roll over the curing membrane under their own weight and adjustable pressure, pressing it firmly and smoothly onto the ground. During this process, the support shaft 4 provides support for the suspended membrane, preventing it from sagging and contacting the water pipe 6.

[0043] When construction is completed or a roll of membrane is used up, stop moving, cut off the water supply, and then you can replace the next roll of membrane or finish the job.
