[0048] Please refer to Figures 1 to 3 This application provides a waterproof membrane laying device, including an installation frame 100, rollers 200, a roll, a compaction component 400, and a tensioning mechanism.

[0049] The mounting bracket 100 includes two fixed frames 110 arranged opposite each other along the first direction D1. The fixed frames 110 extend along the second direction D2. The fixed frames 110 have mounting grooves 111. The mounting grooves 111 extend along the extension direction of the fixed frames 110. The second direction D2 is perpendicular to the first direction D1 and both are parallel to the horizontal plane.

[0050] Roller 200 is mounted on mounting bracket 100.

[0051] The roller is mounted on the fixed frame 110 and is used to install the waterproof membrane 10.

[0052] The compaction assembly 400 includes a compaction shaft 410 and a compaction roller 420. The compaction roller 420 is rotatably connected to the compaction shaft 410 and is located on one side of the roll in the second direction D2 and below the roll.

[0053] The tensioning mechanism includes two tensioning units 500, each corresponding to one end of the compaction shaft 410. Each tensioning unit 500 includes a moving component 510 and an adjusting component 520. The moving component 510 includes a sliding block 511 and a first driving member. The sliding block 511 is slidably mounted in the mounting groove 111 along the second direction D2. The first driving member is connected to the sliding block 511 and is used to drive the sliding block 511 to move. The adjusting component 520 includes an adjusting rod 521 and a second driving member 522 mounted on the sliding block 511. The second driving member 522 is connected to one end of the adjusting rod 521 and is used to drive the adjusting rod 521 to rotate. The other end of the adjusting rod 521 is connected to the corresponding end of the compaction shaft 410.

[0054] In this embodiment of the waterproof membrane laying device, the waterproof membrane 10 is rotatably mounted on the roller. When laying the waterproof membrane 10, the operation causes the free end of the waterproof membrane 10 to roll out. The waterproof membrane 10 rotates, and the operation causes the free end of the waterproof membrane 10 to pass between the compaction roller 420 and the surface to be laid. Through the tensioning mechanism, the tension of the waterproof membrane 10 and the adhesion between it and the surface to be laid are adjusted. The mounting frame 100 is pushed, the roller 200 rotates and drives the mounting frame 100 to move, and the waterproof membrane 10 can be continuously rolled out to lay the waterproof membrane 10 on the surface to be laid. The specific operation of the tensioning mechanism is as follows: The first driving component is activated, which drives the sliding block 511 to move along the second direction D2 within the mounting groove 111. Since the second driving component 522 is mounted on the sliding block 511 and connected to one end of the adjusting rod 521, and the other end of the adjusting rod 521 is connected to the corresponding end of the compaction shaft 410, the moving sliding block 511 can drive the second driving component 522 to move. The moving second driving component 522 can then drive the adjusting rod 521 to move along the second direction D2. Thus, the compaction roller 420 and the waterproof membrane 10 are aligned along the second direction D2. The distance changes, and the tension of the waterproof membrane 10 can be adjusted according to actual needs. In addition, the second drive unit 522 is activated, which drives the adjusting rod 521 to rotate. The adjusting rod 521 drives the compaction shaft 410 to rotate. In this way, the distance between the compaction roller 420 and the ground changes, and the adhesion between the waterproof membrane 10 and the surface to be laid can be adjusted according to actual needs. Furthermore, the distance between the compaction roller 420 and the waterproof membrane 10 in the second direction D2 also changes, and the tension of the waterproof membrane 10 can be further finely adjusted, which is beneficial to keeping the surface of the waterproof membrane 10 flat.

[0055] In this embodiment, the tensioning mechanism can adjust the distance between the compaction roller 420 and the ground, as well as the distance between the compaction roller 420 and the waterproof membrane 10 along the second direction D2, according to the laying requirements. This allows the upper surface of the waterproof membrane 10 to contact the outer circumferential surface of the compaction roller 420, and the lower surface of the waterproof membrane 10 to contact the surface to be laid. The compaction roller 420 can apply pressure to the surface of the waterproof membrane 10, ensuring that the lower surface of the waterproof membrane 10 is tightly fitted to the surface to be laid. Furthermore, the waterproof tension can be adjusted to a suitable level, which is beneficial for the flatness of the waterproof surface. Therefore, the laying quality of the waterproof membrane 10 can be ensured, and the laying efficiency can be improved.

[0056] See also Figures 1 to 3 In some embodiments, the first driving component includes a first motor (not shown in the figure), a rack 5122 and a moving gear 5123. The moving gear 5123 is mounted on the sliding block 511, the rack 5122 is fixedly mounted on the mounting groove 111, the rack 5122 and the moving gear 5123 mesh, and the first motor is connected to the moving gear 5123.

[0057] In this embodiment, when the first driving component is implemented, the first motor is started. The first motor rotates and can drive the moving gear 5123 to rotate. Since the moving gear 5123 meshes with the rack 5122 and the moving gear 5123 is installed on the sliding block 511, the moving gear 5123 can move along the extension direction of the rack 5122. The moving gear 5123 can also drive the sliding block 511 to move along the second direction D2. The compaction roller 420 is indirectly connected to the sliding block 511 through the adjusting rod 521. Therefore, the moving sliding block 511 can drive the corresponding ends of the compaction shaft 410 and the compaction roller 420 to move along the second direction D2, thereby adjusting the tension and flatness of the waterproof membrane 10.

[0058] See also Figure 2 and Figure 3 In some embodiments, the second drive member 522 includes a second motor 5221, a swing drive gear 5222, and a swing driven gear 5223. The output shaft of the second motor 5221 is connected to the axle of the swing drive gear 5222, and the swing drive gear 5222 meshes with the swing driven gear 5223. The axle of the swing driven gear 5223 is connected to one end of the adjusting rod 521.

[0059] In this embodiment, when the second driving member 522 is specifically implemented, the second motor 5221 is started. The second motor 5221 drives the oscillating active gear 5222 to rotate. The oscillating active gear 5222 drives the oscillating passive gear 5223 to rotate. The oscillating passive gear 5223 can drive the adjusting rod 521 to rotate. In this way, the distance between the compaction roller 420 connected to the other end of the adjusting rod 521 and the ground can be changed, as well as the distance between the compaction roller 420 and the waterproof membrane 10 in the second direction D2 can be changed.

[0060] See also Figures 1 to 3 In some embodiments, the adjustment assembly 520 further includes a third drive member 523, which is connected to the adjustment rod 521 and is used to drive the adjustment rod 521 to extend or shorten.

[0061] In one specific embodiment, the third driving component 523 includes a third motor 5231 and a lead screw 5232, one end of which is connected to the output shaft of the third motor 5231; the adjusting rod 521 includes a fixed rod 5211 and a sliding rod 5212, the sliding rod 5212 and the fixed rod 5211 extend in the same direction, the fixed rod 5211 has a sliding groove 502 in the same direction as its own extension, the sliding rod 5212 is installed in the sliding groove 502 and is slidably connected to the side wall of the sliding groove 502; one end of the fixed rod 5211 is connected to the sliding block 511, the lead screw 5232 is disposed in the sliding groove 502, the other end of the lead screw 5232 is screwed to the sliding rod 5212, and the end of the sliding rod 5212 away from the fixed rod 5211 is connected to the corresponding end of the compaction shaft 410.

[0062] In this specific implementation, the third motor 5231 is started, and the third motor 5231 rotates, driving the lead screw 5232 to rotate. The rotating lead screw 5232 drives the sliding rod 5212 to move relative to the fixed rod 5211. The moving sliding rod 5212 drives the corresponding ends of the compaction shaft 410 and the compaction roller 420 to move, thereby changing the distance between the compaction roller 420 and the ground, and changing the distance between the compaction roller 420 and the waterproof membrane 10 in the second direction D2. Thus, this embodiment adds a way to adjust the tension of the waterproof membrane 10 and its adhesion to the surface to be laid, effectively improving the flexibility of the waterproof membrane laying device and enabling the device to better adapt to different construction scenarios and meet diverse operational needs.

[0063] See Figure 3 In some embodiments, a damping spring 501 is fitted onto the lead screw 5232. The two ends of the damping spring 501 are connected to a damping washer 503 and the end of the sliding rod 5212, respectively. The damping washer 503 is installed at the end of the sliding groove 502 away from the sliding rod 5212. This ensures that the adjusting rod 521 experiences movement impact and vibration during extension and retraction, and reduces noise during the extension and retraction process.

[0064] See Figure 1 and Figure 2 In some embodiments, the waterproof membrane laying device further includes an operating handle 600, which is mounted on the mounting frame 100 in the second direction D2, with the reel located between the operating handle 600 and the compaction assembly 400. This allows the construction worker to move the mounting frame 100 by pushing the operating handle 600, thereby facilitating the laying of the waterproof membrane.

[0065] See Figure 2In some embodiments, the waterproof membrane laying device further includes a membrane frame mechanism, which includes two lifting units 700; the roll includes two sub-shafts 310, which are rotatably connected to both ends of the waterproof membrane 10 respectively; each lifting unit 700 includes a connecting frame 710, a lifting motor 720, a lifting threaded rod 730 and a lifting block 740, the connecting frame 710 extends along the vertical direction V, the bottom end of the connecting frame 710 is correspondingly connected to a fixed frame 110, the connecting frame 710 has a lifting groove 711 along its own extension direction, the lifting threaded rod 730 is installed in the lifting groove 711, the lifting block 740 is slidably connected to the lifting groove 711 along the vertical direction V, the sub-shafts 310 are connected to the lifting block 740, the lifting block 740 is screwed to the lifting threaded rod 730, the lifting motor 720 is installed on the connecting frame 710 and connected to the lifting threaded rod 730, and is used to drive the lifting threaded rod 730 to rotate.

[0066] In this embodiment, the height of the waterproof membrane 10 can be adjusted via the membrane frame assembly 700. Specifically, the lifting motor 720 is activated, rotating and driving the lifting threaded rod 730 to rotate. The rotating lifting threaded rod 730 drives the lifting block 740 to move in the vertical direction V. The moving lifting block 740 can drive the sub-shaft 310 to move in the vertical direction V, thereby adjusting the height position of the waterproof membrane 10 connected to the sub-shaft 310. Thus, in this embodiment, in addition to the tensioning mechanism, the tension of the waterproof membrane 10 can also be adjusted via the membrane frame assembly 700. This embodiment adds a way to adjust the tension of the waterproof membrane 10, effectively improving the flexibility of the waterproof membrane laying device and enabling it to better adapt to different construction scenarios and meet diverse operational needs.

[0067] Figure 4 As shown Figure 2 A magnified view of a portion of point A in the middle. Figure 5 The figure shown is an assembly diagram of the limiting unit and the compaction shaft provided in the embodiment of this application.

[0068] See Figure 2 , Figure 4 and Figure 5 In some embodiments, the compaction shaft 410 includes two compaction sub-shafts 411, each compaction sub-shaft 411 being rotatably connected to both ends of the compaction roller 420;

[0069] The waterproof membrane laying device also includes a limiting mechanism, which includes two limiting units 800. Each limiting unit 800 includes a connecting block 810, a fourth driving component 820, an active bevel gear 830, a passive bevel gear 840, a limiting threaded rod 850, a guide plate 860, and an assembly plate 870.

[0070] The bottom end of the adjusting rod 521 is connected to the connecting block 810, which is used to abut against the outer circumferential surface of the compaction roller 420.

[0071] The connecting block 810 has an internal mounting cavity. The fourth driving member 820 is mounted on the connecting block 810 and is connected to the axle of the driving bevel gear 830. The driving bevel gear 830 is rotatably mounted in the mounting cavity, and the driven bevel gear 840 is rotatably mounted in the mounting cavity. The driven bevel gear 840 is sleeved on the outer circumferential surface of the limiting threaded rod 850. The driving bevel gear 830 and the driven bevel gear 840 mesh. The connecting block 810 has a threaded hole and a guide hole. The limiting threaded rod 850 passes through the threaded hole and is screwed to the connecting block 810. The extension direction of the guide plate 860 is parallel to the axial direction of the limiting threaded rod 850. The guide plate 860 passes through the guide hole and is slidably connected to the connecting block. The same end of the limiting threaded rod 850 and the guide plate 860 is connected by the assembly plate 870.

[0072] Each assembly plate 870 is connected to a corresponding compaction sub-shaft 411.

[0073] In this embodiment, during use, the fourth driving component 820 is activated, driving the active bevel gear 830 to rotate. The rotating active bevel gear 830 drives the passive bevel gear 840 to rotate, which in turn drives the limiting threaded rod 850 to rotate. Because the limiting threaded rod 850 is threadedly connected to the connecting block 810, and the connecting plate 810 is slidably connected to the guide plate 860, the rotating limiting threaded rod 850 drives the connecting block 810 to move along the axial direction of the limiting threaded rod 850, thereby changing the distance between the connecting block 810 and the compaction sub-shaft 411. This is because during the laying process, the compaction roller 420 will... When pressure is applied to the surface of the waterproof membrane 10, the compaction roller 420 will rotate under the dynamic friction of the waterproof membrane 10. Under the premise that the diameter of the compaction roller 420 is constant, when the distance between the connecting block 810 and the compaction sub-shaft 411 increases, the friction of the connecting block 810 on the compaction roller 420 decreases, and the rotation speed of the compaction roller 420 is greater (compared to when the distance between the compaction roller 420 and the connecting block 811 decreases). Under the premise of a certain laying time, a larger area of ​​waterproof membrane can be laid, and vice versa. In addition, changing the distance between the connecting block 810 and the compaction sub-shaft 411 can accommodate the installation of compaction rollers 420 with different diameter specifications.
