Abstract
Description
Technical Field
[0001] This utility model relates to a waterproof membrane laying machine for high-speed railway bridge decks, belonging to the technical field of road and bridge construction equipment. Background Technology
[0002] Waterproofing is crucial during high-speed rail construction. The bridge deck between the track slabs requires waterproofing, typically involving spraying a waterproof coating, laying a waterproof membrane, and then paving with waterproof concrete. The installation of the waterproof membrane is particularly important. Due to the limited space on the high-speed rail bridge deck, the waterproof membrane is usually installed manually using simple equipment.
[0003] Traditional, simple equipment lacks comprehensive functionality, particularly in its poor compaction of the waterproof membrane after installation, resulting in poor adhesion between the membrane and the bridge deck. Existing equipment is inadequate in compacting the waterproof membrane, primarily because most devices only have a single compaction component, failing to adequately roll the membrane. This leads to gaps and air bubbles between the membrane and the bridge deck, hindering a dense and compact installation and severely impacting the quality and effectiveness of the waterproofing. Utility Model Content
[0004] The purpose of this invention is to provide a high-speed railway bridge deck waterproof membrane laying and bonding machine to solve the above-mentioned technical problems.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-speed railway bridge deck waterproof membrane laying and bonding machine includes a main support with traveling wheels, a waterproof membrane rotatably mounted on the main support, several flame nozzles for spraying flames onto the waterproof membrane, and pressure rollers for pressing the waterproof membrane onto the bridge deck; the flame nozzles are connected to an air tank through pipes; several rows of pressure rollers are arranged in rows behind the pressure rollers; multiple pressure rollers are arranged laterally in each row, and adjacent rows of pressure rollers are staggered longitudinally.
[0006] A further improvement to the technical solution of this utility model is that several guide rollers are set between the waterproof membrane and the pressure roller.
[0007] A further improvement to the technical solution of this utility model is that the pressure roller is mounted on the pressure roller bracket, and the pressure roller bracket is mounted on the lower end face of the main bracket.
[0008] A further improvement to the technical solution of this utility model is that the pressure roller is movably mounted on the pressure roller bracket, and a spring is provided to give the pressure roller a buffering effect.
[0009] A further improvement to the technical solution of this utility model is that two sets of pressing wheels are also provided to press the edges of the waterproof membrane; the pressing wheels are located at both ends of the main support.
[0010] A further improvement to the technical solution of this utility model is that anti-collision wheels are provided on the outer sides of both ends of the main support; lifting mechanisms are provided at both ends of the main support, and the main support is installed on the traveling wheels through the lifting mechanisms.
[0011] A further improvement to the technical solution of this utility model is as follows: 2-3 gas cylinders are set on the main support; the flame nozzles are arranged in rows evenly; and the flame nozzles have built-in temperature sensors.
[0012] Due to the adoption of the above technical solution, the technical effects achieved by this utility model are as follows: This utility model is a waterproof membrane laying and bonding machine for high-speed railway bridge decks. The main support is designed with a compact overall structure, making the whole machine small and suitable for construction in narrow areas on high-speed railway bridge decks.
[0013] The waterproof membrane laying machine of this utility model is equipped with a pressure roller for pre-compression and a multi-row pressure roller for further compaction. The cooperation of the pressure roller and the multi-row pressure roller achieves full compaction of the waterproof membrane, thereby improving the laying quality.
[0014] This invention features edge-pressing wheels at both ends of the main support, which further press the edges of the waterproof membrane to ensure effective compaction.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0021] This utility model relates to a waterproof membrane laying machine for high-speed railway bridge decks, applicable to the installation of waterproof membranes in narrow areas of high-speed railway bridge decks. High-speed railway bridge decks have track slabs, and waterproofing treatment is required between adjacent track slabs, necessitating the application of a waterproof coating before laying the waterproof membrane. This machine has a compact structure and is suitable for construction in narrow areas of high-speed railway bridge decks.
[0022] like Figure 1 , Figure 2 , Figure 3 As shown, the waterproof membrane laying and bonding machine mainly includes a main support 1, a flame nozzle 3 mounted on the main support 1, and a pressure roller 4 for pressing the waterproof membrane 2 onto the bridge deck. The lower part of the main support 1 is equipped with traveling wheels 11, which are driven by a drive mechanism formed by a motor and reducer. During operation, the traveling wheels 11 travel along the retaining wall. The main support 1 has a bracket for placing the waterproof membrane 2, which is rotatably mounted on the bracket. During laying, the waterproof membrane 2 rotates and releases. The flame nozzle 3 sprays flame onto the side of the waterproof membrane to be laid and bonded, melting the adhesive layer; then, the pressure roller 4 pre-presses and bonds the waterproof membrane onto the bridge deck. The pressure roller 4 is a roller structure.
[0023] The traveling wheels 11 on the main support 1 are preferably rubber wheels.
[0024] To improve the adhesion of the waterproof membrane, multiple pressure rollers 6 are installed behind the pressure roller 4. The pressure rollers 6 are small roller structures. They are arranged in rows, with multiple rows typically. At least two rows of pressure rollers 6 are usually installed. Multiple rollers are arranged laterally within each row. Adjacent rows of pressure rollers 6 are staggered longitudinally, with the gap between two adjacent rollers 17 in the previous row corresponding to the pressure roller 17 in the next row. This ensures effective compaction of the waterproof membrane at all locations, thoroughly expelling air and achieving a high degree of adhesion between the membrane and the bridge deck.
[0025] The machine is equipped with multiple flame nozzles 3 arranged in a row. The flame nozzles 3 are located at the lower part of the main support 1, in front of and below the waterproof membrane 2. The flame nozzles 3 are connected to a gas tank 5, which typically contains liquefied petroleum gas. The flame nozzles 3 and gas tank 5 are connected via pipes. In practical implementation, a temperature sensor is preferably built into the flame nozzle 3 to dynamically adjust the flame temperature, preventing overheating or insufficient melting and ensuring optimal bonding layer condition.
[0026] In practice, at least two gas cylinders 5 are typically installed to improve continuous operation capability. The flame nozzles 3 are arranged in a row and evenly distributed, providing uniform heat and enabling rapid melting of the adhesive layer on the surface of the waterproof membrane.
[0027] The waterproof membrane laying machine is as follows: Figure 3 , Figure 4 As shown, the waterproof membrane 2 is rotatably mounted on the main support 1, and then released during the laying process. The outer end of the waterproof membrane 2 is adhered to the bridge deck, and pre-pressing is achieved by the pressure roller 4. Several guide rollers 7 are usually set between the waterproof membrane 2 and the pressure roller 4 to smoothly guide the waterproof membrane 2 downwards, and finally it is adhered to the bridge deck by the pressure roller 4. Figure 3 and Figure 4 The waterproof membrane 2 turns after passing the first guide roller 7, and then turns downward after being guided by the second guide roller and the third guide roller.
[0028] The waterproof membrane laying machine is equipped with pressure rollers 4 for pre-compression, and then multiple rows of pressure rollers 6 for thorough compaction of the waterproof membrane. Specifically, a pressure roller bracket 8 is provided on the lower end face of the main support 1, and the pressure rollers 6 are mounted on the pressure roller bracket 8. Furthermore, the pressure rollers 6 are not directly fixed to the pressure roller bracket 8, but are movably mounted on the pressure roller bracket 8. Usually, a spring is used, and the pressure roller is movably mounted on the pressure roller bracket 8 through a mounting shaft, with the spring fitted outside the mounting shaft; the spring is used to achieve the installation of the pressure roller 6, giving the pressure roller 6 a buffer and improving the compaction effect.
[0029] The waterproof membrane laying machine is also equipped with two sets of edge pressing rollers 9, which, as the name suggests, are used to further compact the edges of the waterproof membrane. The edge pressing rollers 9 are located behind the pressing rollers 6 and are set at both ends of the main support 1 to ensure that the edges of the waterproof membrane are compacted.
[0030] This waterproof membrane laying machine travels along a retaining wall during operation, with the area below the side of the retaining wall being the area where the waterproof membrane needs to be laid. Anti-collision wheels 12 are installed on the outer sides of both ends of the main support 1. At least two anti-collision wheels 12 are installed on each side, ensuring the machine travels along the side of the retaining wall and guaranteeing stable movement. Specifically... Figure 5 , Figure 6 As shown.
[0031] This waterproof membrane laying machine can be equipped with lifting mechanisms 10 at both ends of the main support 1, which are used to mount the main support 1 onto the traveling wheels 11. The lifting mechanism 10 can be a screw jack. Height adjustments are made via the lifting mechanism 10 before and after laying, but generally not during the waterproof membrane laying process.
[0032] The waterproof membrane laying machine is equipped with a control system and can also be remotely controlled, allowing operators to control it remotely.
[0033] In addition, a lifting trolley is set up along the walking route. The trolley is equipped with a crane to lift the waterproof membrane onto the waterproof membrane laying machine. Because the waterproof membrane is heavy, it is more convenient to lift it by crane.
[0034] A specific site for the implementation of this equipment is a high-speed railway double-track bridge with a deck width of 810m, a retaining wall spacing of 2.1m on both sides, and a waterproof membrane width of 2.1m.
[0035] This utility model of a waterproof membrane laying machine has a compact and small overall structure, making it suitable for construction in confined areas. By setting pre-pressing rollers and multiple rows of pressure rollers, the waterproof membrane is fully compacted, improving the laying quality.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
