Description

Technical Field

[0001] The present invention relates to the technical field of building construction equipment, in particular to a coiled material hot-melt paving device for ground construction. Background Art

[0002] Waterproof membrane is a rollable sheet-like waterproof material that forms a continuous waterproof layer by paving to prevent water penetration. It is widely used in building roofs, basements, kitchens and bathrooms. As the "first line of defense" for building waterproofing, the performance and construction quality of waterproof membrane are directly related to the service life of the building.

[0003] When laying waterproof membranes manually, the manual operation is limited by the physical load and laying speed. The average daily working area of ​​a single person is usually less than a square meter. In large-scale projects, construction delays are prone to occur. In addition, manual laying requires the collaboration of multiple people to complete the handling, cutting, and positioning processes. The time loss in the process connection is significant. For example, the waste of materials caused by the cutting error of the membrane requires rework and adjustment, which further reduces the overall efficiency. In this process, the wrinkle problem is caused by the uneven force control when manually stretching the membrane. At complex nodes such as the corners, it is difficult for manual labor to accurately fit the contour of the base layer, resulting in local wrinkles. Hidden dangers of leakage in the later stage include hollowing phenomenon, which is mostly caused by incomplete cleaning of the base layer or uneven glue application. It is difficult to ensure close contact across the entire width by manual pressing. Temperature control during manual hot-melt welding relies on experience, which leads to carbonization of the roll material, which will cause the seal at the overlap to fail. It is more likely to warp and crack under temperature changes. In addition, manual operation is significantly affected by the environment and personnel status. The softening of the roll material in high temperature weather makes it difficult to lay and position it. The flexibility of the material decreases in low temperature environment, which makes it easy to tear. The technical level of workers is uneven, which not only affects the one-time acceptance rate of the project, but also increases the later maintenance costs. Summary of the Invention

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] According to existing solutions and technologies, traditional manual laying of roll materials has the following problems:

[0034] Traditional manual laying can easily lead to low efficiency and poor quality of waterproof membranes due to different workers' skills;

[0035] In terms of quality, uneven manual stretching force causes wrinkles, incomplete base cleaning causes hollowing, hot melt welding temperature control relies on experience, causes warping and cracking, and is greatly affected by the environment and personnel, high and low temperatures are prone to problems, and workers' skills are different, which affects the acceptance rate and increases maintenance costs.

[0036] The present invention realizes the automated construction of the entire process of "unwinding - preheating - hot melting - compacting - cutting" through the coordinated operation of the driving mechanism and the paving mechanism. The driving mechanism provides travel power and adaptively adjusts the height of the equipment. The paving mechanism melts the adhesive layer of the roll material through a two-stage heating system, and cooperates with the precise transmission and compaction system to achieve efficient and precise paving of the waterproof roll material, solving the efficiency and quality pain points of traditional manual construction.

[0037] In order to solve the above problems, the present invention provides a technical solution. Figure 1 、 Figure 2 as well as Figure 9 Shown: A hot-melt paving device for coiled materials used in ground construction, comprising a driving mechanism 1 and a paving mechanism 2;

[0038] The paving mechanism 2 includes a main body box 21, a set of bearing bodies 26, an electric telescopic frame 27 and a fixed circuit loop 28;

[0039] A set of electric telescopic frames 27 are fixedly installed on the top of the main box 21. An air roller 271 is rotatably connected to the interior of the electric telescopic frames 27. Four preheating plates 272 are fixedly connected to the outer wall of the air roller 271. Four sets of burners 273 are fixedly connected to the outer wall of the air roller 271. The four sets of burners 273 are all located behind the preheating plates 272 and roll. A fixed circuit loop 28 is fixedly connected to one side of the inner wall of the main box 21. The input ends of the four preheating plates 272 are fixedly connected to contact rings 274. The four contact rings 274 are rotatably connected to the interior of the fixed circuit loop 28.

[0040] A group of bearing bodies 26 are respectively installed between the inner surface walls of the main body box 21, and a compacting roller 261 is rotatably connected between the inner surface walls of the group of bearing bodies 26.

[0041] Specifically, during the use of the equipment, combustible gas is stored in the interior of the air roller 271 for preliminary storage. The air roller 271 is made of high-temperature resistant aluminum alloy, and its surface is ceramic spray-coated for high-temperature resistance. The four burners 273 are dedicated propane gas burners, each with a heat load of 1.2kW and an adjustable flame temperature of 180-200°C. The four preheating plates 272 are 80mm apart, and the four preheating plates 272 are stainless steel electric heating plates with a surface temperature maintained at 60-80°C. The preheating width covers the web width. The preheating plates 272 and burners 273 cooperate to form four sets of "softening first and then melting" dual-stage heating modes.

[0042] The fixed circuit loop 28 is made of a copper conductive ring with a gold-plated surface. The fixed circuit loop 28 is also equipped with an overload protection function. When the current exceeds 1.2 times the rated value, the power is automatically cut off to prevent the friction heat generated by the contact ring 274 from causing a fire. In combination with the graphite brush of the contact ring 274, four groups of "softening first and then melting" modes are realized to achieve cyclic connection, thus avoiding circuit failure caused by traditional wire entanglement.

[0043] The surface of the compacting roller 261 is covered with thick silicone rubber, and a pressure sensor is set inside. The pressure is adjusted by the lifting amount of the electric telescopic frame 27, and can be adjusted steplessly within the range of 0.3-0.8MPa to ensure that the bonding strength between the coil and the base layer is ≥0.6MPa.

[0044] More specifically: Figure 6 As shown, a group of bearing seats A22 are fixedly installed inside the main box 21, and a driving rod 221 is rotatably connected between the inner surface walls of a group of bearing seats A22. A locking groove 2211 is preset inside a group of driving rods 221. The locking groove 2211 adopts a trapezoidal cross-section (upper bottom 15mm, lower bottom 20mm, depth 12mm). A locking block 2212 is movably embedded in the interior of a group of locking grooves 2211, forming an interference fit with the locking block 2212. A coil roller 222 is fixedly connected between one side of the outer wall of a group of locking blocks 2212. A fixed locking ring 223 is movably sleeved between the connection between a group of locking grooves 2211 and the locking block 2212. The fixed locking ring 223 is a threaded locking type, which supports the quick replacement of the coil roller 222.

[0045] In some embodiments, according to Figure 4 and Figure 5 As shown, a group of driving rods 221 are fixedly connected to a gear A224 on one side of the outer wall, thereby realizing the linkage state between the driving rods 221 and the gear A224. A group of bearing seats B23 are fixedly installed inside the main box 21. A transfer roller 231 is rotatably connected between the interior of a group of bearing seats B23. A gear B232 is fixedly connected to one side of the outer wall of the transfer roller 231, and the gear B232 and the transfer roller 231 are also linked. The gears A224 and B232 rotate in the same direction and frequency with each other through the linkage belt 24. The outer walls of the gears A224 and B232 are transmission-connected with a linkage belt 24. The gears A224 and B232 are both involute spur gears with a module of 2mm, a number of teeth of 24 and 36 respectively, a transmission ratio of 1:1.5, and cooperate with the linkage belt 24 to ensure that the unwinding tension of the coil is stable at 8-12N.

[0046] More specifically: Figure 4 and Figure 5As shown, an internal drive motor 211 is fixedly installed inside the main body box 21, and the internal drive motor 211 is energized to convert it into mechanical energy. A transmission box 2111 is fixedly connected to one side of the outer wall of the main body box 21, and the mechanical energy is transmitted to the inside of the transmission box 2111. The output end of the internal drive motor 211 is fixedly connected to the input end of the transmission box 2111. With the transmission box 2111 as a medium, the interior of the main body box 21 is rotatably connected to a linkage rod 212, and the output end of the transmission box 2111 is fixedly connected to one side of the outer wall of the linkage rod 212. The outer wall of the linkage rod 212 is fixedly connected to a transmission gear 213, and the outer wall of the transmission gear 213 is transmission-connected to a gear belt 214. The gear belt 214 is transmission-connected between one of the outer walls of a group of driving rods 221, so as to maintain the rotation of the linkage rod 212.

[0047] A group of internal plates 25 are fixedly installed inside the main box 21, and a slide 251 is fixedly connected between one side of the outer wall of the group of internal plates 25. A micro cylinder 252 is fixedly installed inside the slide 251, and a cutting blade 253 is fixedly connected to the telescopic end of the micro cylinder 252. The cutting blade 253 is slidably embedded in the inside of the slide 251. The micro cylinder 252 pushes the cutting blade 253 to complete the cutting at a speed of 1.2m / s. The blade edge angle is 30°. Combined with the linear guide rail of the slide 251, the cutting error is ≤0.5mm, which is suitable for cutting 3-5mm thick waterproof rolls.

[0048] In some embodiments, the driving mechanism 1 includes a driving box 11, the output end of the driving box 11 is rotatably connected to two driving wheels 12, a group of adjusting cylinders 13 are fixedly connected to one side of the outer wall of the driving box 11, and the telescopic ends of a group of adjusting cylinders 13 are fixedly connected to connecting plates 14, and a group of connecting plates 14 are respectively fixedly connected to the inner surface walls of the main box 21.

[0049] Working principle: First, before using the equipment, the coil roller 222 needs to be replaced. First, a set of driving rods 221 are preset with a snap-fit ​​groove 2211 inside. The snap-fit ​​groove 2211 adopts a trapezoidal cross-section. A set of snap-fit ​​grooves 2211 are movably embedded with a snap-fit ​​block 2212 inside, which forms an interference fit with the snap-fit ​​block 2212, so that the coil roller 222 can be firmly clamped inside the two driving rods 221. Then the fixed locking ring 223 is a threaded locking type, which is tightly locked between the coil roller 222 and the two driving rods 221, thereby realizing the locking of the three. Then, according to Figure 10 , the coil is processed according to the route shown and is folded back;

[0050] Then the driving box 11 has a built-in three-stage gear reduction box to drive the driving wheel 12 to move at a high speed. In this process, the combustible gas inside the air roller 271 is transmitted to the inside of the four groups of burners 273, driving the four stainless steel preheating plates 272 to conduct electricity with the fixed circuit loop 28 through the contact ring 274, maintaining the surface temperature of the preheating plate 272 at 60-80°C, softening the bottom surface adhesive layer of the coil in advance during the rolling process, covering 80% of the width of the coil, and the four groups of propane burners 273 ignited 5 seconds later, maintaining a distance of 80mm from the preheating plate 272, raising the temperature to 180-200°C, and the fixed circuit loop 28 is set to 1 .2 times overload protection, contact ring 274 graphite brush, forming a "softening first and then melting" continuous heating zone to avoid carbonization of the coil, and in the process of the equipment moving forward, keep the hot melt side in contact with the ground, and then the compaction roller 261 can roll from its top, plus the direct application of the equipment's own weight, the compaction roller 261 crushes and discharges the air between the coil and the base layer, so that the coil and the base layer are firmly bonded, and finally the micro cylinder 252 in the slide 251 pushes the cutting blade 253 at a speed of 1.2m / s, and the paving length is detected by the encoder. After reaching the set value (such as 10m), the cutting is completed within 0.5 seconds, and the cutting error is small.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
