Description

Technical Field

[0001] This utility model relates to the technical field of waterproof membrane construction equipment, and in particular to a device for bonding, laying and fixing waterproof membranes in underground railway engineering. Background Technology

[0002] Waterproof membrane is a building material used to prevent water leakage and is widely used in various construction projects. In railway engineering, waterproof membrane is mainly used for waterproofing projects in railway tunnels, bridges, underground garages, pump rooms, flood control dikes, etc.

[0003] In the construction of underground railway projects, waterproof membranes are mostly laid manually, but this process has some drawbacks, mainly:

[0004] 1. The installation of waterproof membrane requires a high level of precision and a flat substrate, which presents a certain challenge. In addition, the skill level of the construction workers can lead to inconsistent construction quality, making it difficult to control the quality of the work. For example, if the surface of the membrane is uneven after installation, it may not be able to bond effectively with the concrete surface, resulting in a layer of groundwater between the waterproof membrane and the concrete structure. This will be a serious hidden danger to the overall integrity of the waterproofing in the future.

[0005] 2. When laying roll materials, due to the large laying area, the overlap length is not easy to control, and the overlap length is easily too small, failing to meet the specifications. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that the laying of waterproof membrane is difficult in the existing technology, resulting in inconsistent construction quality. It proposes a device for bonding, laying and fixing waterproof membrane in underground railway engineering.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A device for bonding, leveling, and fixing waterproof membranes used in underground railway engineering includes a frame, an electric roller, and a pressing roller. The electric roller is detachably connected to the frame, and a disassembly and assembly assembly is provided between the electric roller and the frame. The pressing roller is located at the lower part of the frame, and an adjustment device is provided between the pressing roller and the frame for adjusting the height of the pressing roller. The frame has scale lines on its exterior.

[0009] In some embodiments, the electric roller includes a spool and a motor, the motor being fixed to the outside of the frame, and the spool and the motor being connected by a transmission. The frame is provided with two bearing seats, and the spool is mounted on the two bearing seats by a disassembly assembly.

[0010] In some embodiments, the disassembly and assembly assembly includes a connecting shaft, a transmission component, a sleeve, and an insert shaft. The transmission component is shaped like a polygonal prism and is fixed to one end of the reel near the motor. The connecting shaft is mounted on a bearing seat near the motor via a bearing, and one end of the connecting shaft has a transmission hole adapted to the transmission component, into which the transmission component is inserted.

[0011] In some embodiments, the sleeve is mounted on a bearing seat on the side away from the motor via a bearing, the insert shaft is inserted into the sleeve, the insert shaft is slidably connected to the end of the reel away from the motor, a return spring is connected between the insert shaft and the reel, and a handle is provided on the insert shaft.

[0012] In some embodiments, the adjusting device includes a bracket, a sliding frame, a nut, and a threaded shaft.

[0016] Compared with the prior art, this utility model provides a device for bonding, laying and fixing waterproof membranes in underground railway engineering, which has the following beneficial effects.

[0017] 1. This utility model allows for the laying of waterproof membrane by pulling the device during its movement. Compared to manual laying, using this device is undoubtedly more convenient and labor-saving, thereby improving work efficiency to a certain extent. During the laying process, the compression rollers also press the waterproof membrane firmly onto the concrete surface, ensuring effective adhesion between the waterproof membrane and the concrete surface. This effectively prevents the presence of groundwater between the waterproof membrane and the concrete structure. Furthermore, the scale lines allow for real-time measurement of the overlap between adjacent waterproof membranes during laying, ensuring effective overlap between the waterproof membranes and enabling the laying construction to better meet specifications and further guarantee the stability of the laying quality.

[0018] 2. This utility model, through the setting of disassembly and assembly components, makes the replacement of waterproof membrane more convenient and easy to operate, improving the usability of the device. By adjusting the device, the height of the extrusion roller can be adapted to the thickness of the waterproof membrane, so that the extrusion roller can compact waterproof membranes of different thicknesses, thereby improving the adaptability and versatility of the device.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figure 1-3 A device for bonding, leveling, and fixing waterproof membranes used in underground railway engineering includes a frame 1, an electric roller 2, and a compression roller 3. The electric roller 2 is detachably connected to the frame 1. Before laying, the waterproof membrane 10 is pre-wound and stored on the electric roller 2. A disassembly assembly is provided between the electric roller 2 and the frame 1 to facilitate the installation and replacement of the waterproof membrane 10. The compression roller 3 is located at the lower part of the frame 1 and is used to compact the waterproof membrane 10 laid on the ground to ensure the quality of construction. A connection is provided between the compression roller 3 and the frame 1. The adjusting device 4 is used to adjust the height of the extrusion roller 3 so that the extrusion roller 3 can compact waterproof membrane 10 of different thicknesses. The lower part of the frame 1 is provided with wheels 5, and the outer side of the frame 1 is provided with scale lines 9. The length direction of the scale lines 9 is parallel to the axis direction of the extrusion roller 3 so that the overlap between two adjacent waterproof membranes 10 in the width direction can be measured in real time during laying, so that two adjacent waterproof membranes 10 laid on the ground can effectively overlap in the width direction, further ensuring the stability of the laying quality.

[0031] The frame 1 is equipped with a handrail 7 on the outside, which is used to push or pull the frame 1 to move. During the movement, the electric roller 2 will also rotate, which will slowly release the waterproof membrane 10 wrapped around it and lay it on the ground. Then, under the action of the squeezing roller 3, the waterproof membrane 10 will be pressed firmly on the ground.

[0032] The outer surface of the extrusion roller 3 is provided with a soft covering layer 301, which can be made of silicone or rubber, so that the extrusion roller 3 can also protect the waterproof membrane 10 to a certain extent during the process of compacting the waterproof membrane 10, thereby preventing damage to the waterproof membrane 10.

[0033] The frame 1 is equipped with a braking device 6, which is used to brake the wheel 5, making it easier to fix the device and improve its stability.

[0034] Reference Figure 4-6 The electric roller 2 includes a roller 12 and a motor 13. The motor 13 is fixed to the outside of the frame 1. The roller 12 and the motor 13 are connected by a transmission. The roller 12 is arranged in parallel with the extrusion roller 3. The frame 1 is provided with two bearing seats 11. The roller 12 is installed on the two bearing seats 11 through a disassembly assembly.

[0035] The assembly and disassembly components include a connecting shaft 14, a transmission component 16, a sleeve 17, and an insert shaft 18. The transmission component 16 is prism in shape and is fixed to one end of the reel 12 near the motor 13. The connecting shaft 14 is mounted on a bearing seat 11 near the motor 13 via a bearing. One end of the connecting shaft 14 has a transmission hole 15 that matches the transmission component 16. The transmission component 16 is inserted into the transmission hole 15.

[0036] The sleeve 17 is mounted on the bearing seat 11 on the side away from the motor 13 via a bearing. The insert shaft 18 is inserted into the sleeve 17. The insert shaft 18 is slidably connected to the end of the reel 12 away from the motor 13. A return spring 20 is connected between the insert shaft 18 and the reel 12. The insert shaft 18 is provided with a handle 19.

[0037] After the waterproof membrane 10 on the roller 12 is laid, the roller 12 needs to be replaced with a roller 12 that has been wound with the waterproof membrane 10. The specific operation is as follows: First, turn the handle 19 towards the transmission component 16, thereby pulling the insert shaft 18 inward and sliding it into the roller 12, so that the insert shaft 18 is completely pulled out from the sleeve 17 and moved away from the sleeve 17 at a certain distance. Then, pull the roller 12 towards the sleeve 17, thereby pulling the transmission component 16 out of the transmission hole 15, and the roller 12 can be removed from the device. Then, prepare a roller 12 with the waterproof membrane 10 wound on it, and also turn the handle 19 towards the sleeve 16. Pull the handle 19 to retract the insert shaft 18 into the roll 12. During this process, the insert shaft 18 and the roll 12 will compress the return spring 20. Then, move the roll 12 between the two bearing seats 11 and insert the transmission component 16 on the roll 12 into the transmission hole 15. At the same time, ensure that the insert shaft 18 is aligned with the sleeve 17. Then release the handle 19. Under the rebound force of the return spring 20, the insert shaft 18 will be pushed outward from the roll 12 and reset and inserted into the sleeve 17. This completes the replacement of the roll 12. The replaced roll 12 can be reused after being rewound with the waterproof membrane 10, avoiding waste of materials.

[0038] Reference Figure 3 and Figure 7 The adjusting device 4 includes a bracket 401, a sliding frame 403, a nut 404 and a threaded shaft 405. The lower part of the bracket 401 is provided with a guide rail 402. The sliding frame 403 is slidably connected to the guide rail 402. The extrusion roller 3 is connected to the sliding frame 403 through a bearing. The nut 404 is fixed to the bracket 401. The threaded shaft 405 is threadedly connected to the bracket 401, and one end of the threaded shaft 405 is connected to the sliding frame 403.

[0039] When it is necessary to adjust the height of the extrusion roller 3 according to the thickness of the waterproof membrane 10, the threaded shafts 405 on both sides are turned, which, in cooperation with the nuts 404, allows the threaded shafts 405 to slide up or down, thereby driving the sliding frame 403 to slide synchronously on the guide rail 402, and thus the extrusion roller 3 moves synchronously, thereby adjusting the distance between the extrusion roller 3 and the ground, so that the extrusion roller 3 can compact waterproof membranes 10 of different thicknesses.

[0040] In this utility model, when laying the waterproof membrane 10, the outer end of the waterproof membrane 10 is first pulled to the bottom of the extrusion roller 3, and the starting position of the waterproof membrane 10 is laid. Then, the height of the extrusion roller 3 is adjusted by the adjustment device 4 so that its height matches the thickness of the waterproof membrane 10. Then, the brake device 6 is opened to release the lock on the wheel 5. Next, the motor 13 is started so that it drives the roller 12 to rotate slowly, thereby slowly releasing the waterproof membrane 10 wound on the outside. At the same time, the device is moved along the laying direction by the handrail 7. During this process, the waterproof membrane 10 can be laid on the ground. The movement of the extrusion roller 3 will also compact the waterproof membrane 10 on the ground, so that it is tightly attached to the ground. When pulling, the overlap length between two adjacent waterproof membranes 10 can be observed through the scale line 9 to ensure that the overlap meets the requirements.

[0041] When the waterproof membrane 10 on the roll 12 is used up, another roll 12 with waterproof membrane 10 wound on it can be replaced by disassembling and assembling the assembly.
