[0030] Please see Figure 1 and Figure 2 This application provides a bridge roof waterproof membrane laying device 10, which may include a traveling mechanism 100, a compaction assembly 300, and a heating assembly 400. The traveling mechanism 100 is provided with a winding section 110 for winding and laying the membrane 200. When the traveling mechanism 100 travels on the bridge deck, it can pull the membrane 200 from the winding section 110 and lay it on the bridge deck, so that the membrane 200 laid on the bridge deck forms a laying portion. The compaction assembly 300 is connected to the traveling mechanism 100 and is used to compact the laid portion of the membrane 200. The heating assembly 400 is connected to the traveling mechanism 100 and is used to heat the membrane 200.

[0031] When using the bridge roof waterproof membrane laying device 10 described in this application, the traveling mechanism 100 can be placed on the bridge surface first, then the discharge end of the membrane 200 can be pulled and laid on the bridge surface, and then the laying part of the membrane 200 can be pressed and fixed on the bridge surface by the rolling component 300. In this way, under the traction of the traveling mechanism 100 and the rolling action of the rolling component 300, the membrane 200 can automatically complete the rolling and unrolling operation and be laid on the bridge surface, and at the same time, it can be compacted on the bridge surface by the rolling component 300.

[0032] In addition, this application also includes a heating component 400, which helps to heat and soften the roll material 200 during the laying process, thereby improving the adhesion of the roll material 200 to the bridge deck.

[0033] Therefore, the bridge roof waterproof membrane laying device 10 described in this application can realize the integrated construction of automatic unfolding, automatic heating and melting and automatic compaction of the membrane 200 laying operation, thereby improving the efficiency and quality of construction.

[0034] It is worth noting that the present application solves the problem of high labor intensity of manual heating operation in related technologies by fixing the heating component 400 to the walking mechanism 100 to heat the roll material 200, as well as the problems of uneven heating and poor heating quality consistency caused by manual heating operation.

[0035] Optionally, the winding portion 110 of the walking mechanism 100 described above in this application can be a rotating shaft, and the aforementioned roll material 200 can be wound around the rotating shaft to achieve the winding and unwinding operation.

[0036] In some embodiments, a connecting portion 210 is provided between the laid portion of the roll 200 and the wound portion wound on the winding portion 110, and the heating assembly 400 is used to heat the connecting portion 210, which helps to ensure the softening effect of heating the roll 200 and ensure the consistency of the heating quality of the roll 200.

[0037] Understandably, such as Figure 2 As shown, the aforementioned connecting portion 210 is generally arranged at the bottom of the winding portion of the roll material 200. The heating component 400 can heat this portion. Since the heating component 400 is fixed on the traveling mechanism 100, the distance between the heating component 400 and the connecting portion 210 of the roll material 200 can be fixed at the same time. This ensures the consistency of the heating quality of the heating component 400 on the roll material 200, thereby improving the heating and softening effect of the roll material 200 and ensuring the strong adhesion of the roll material 200 on the bridge surface.

[0038] In addition, since the connecting part 210 is configured as the connection position between the laying part and the winding part of the roll material 200, the roll material 200 can be laid on the bridge surface in a timely manner after heating, thereby ensuring the heating and heat preservation performance of the heating component 400 on the roll material 200, improving the heating and softening effect of the roll material 200, and ensuring the strong adhesion of the roll material 200 on the bridge surface.

[0039] In some embodiments, the heating assembly 400 may include a heating gun 410 and a combustion-supporting mechanism 420, with the heating gun 410 and the combustion-supporting mechanism 420 connected, thereby ensuring the continuous heating and softening effect of the heating gun 410 on the roll material 200.

[0040] Optionally, the aforementioned heating gun 410 may be configured, but is not limited to, to employ a fan-shaped flame arrangement, which helps to heat the width of the roll 200 and avoid localized overheating.

[0041] Optionally, the aforementioned combustion-supporting mechanism 420 may be implemented as an oxygen-acetylene cylinder, but is not limited to that implemented as an oxygen-acetylene cylinder.

[0042] Optionally, the aforementioned combustion-supporting mechanism 420 can be mounted on the traveling mechanism 100. Specifically, the combustion-supporting mechanism 420 can be fixed to the side of the traveling mechanism 100 via a metal protective frame. Optionally, the combustion-supporting mechanism 420 can be equipped with a safety valve and a shock-absorbing pad to ensure construction safety.

[0043] In some embodiments, the heating gun 410 is rotatably connected to the walking mechanism 100, and the heating gun 410 can rotate relative to the walking mechanism 100 to adjust the alignment angle of the heating gun 410 relative to the connecting part 210, so as to ensure the heating and softening effect of the heating gun 410 on the roll material 200.

[0044] In some embodiments, the heating assembly 400 may further include a temperature sensor for monitoring the heating temperature of the heating gun 410. Thus, by displaying the temperature of the temperature sensor, the heating temperature of the heating gun 410 on the roll 200 can be adjusted in a timely manner to ensure the heating and softening effect on the roll 200.

[0045] Specifically, users can adjust the setting angle of the heating gun 410 and the setting distance of the heating gun 410 relative to the connecting part 210 of the roll material 200 according to the target heating temperature and the temperature display of the temperature sensor, so as to ensure the heating and softening effect of the roll material 200.

[0046] Optionally, in some other embodiments, the aforementioned combustion-supporting mechanism 420 may be equipped with a pressure regulating valve, so that the combustion-supporting force of the combustion-supporting mechanism 420 can be adjusted in real time according to the actual heating temperature, so as to ensure the heating and softening effect of the heating gun 410 on the roll material 200.

[0047] In some embodiments, the rolling assembly 300 may include an extension arm 310 and a pressure roller 320. One end of the extension arm 310 is connected to the traveling mechanism 100, and the pressure roller 320 is connected to the other end of the extension arm 310. The pressure roller 320 is used to roll the laid portion of the roll material 200. Thus, during the movement of the traveling mechanism 100, the pressure roller 320 can roll and roll on the surface of the laid portion of the roll material 200, thereby improving the flatness of the laid roll material 200.

[0048] Optionally, the aforementioned pressure roller 320 may be covered with high-temperature resistant polyurethane material or heat-resistant rubber material, which helps to improve the wear resistance of the pressure roller 320 and ensure that the pressure roller 320 has a certain degree of elasticity to ensure the compaction quality of the pressure roller 320.

[0049] In some embodiments, the compaction assembly 300 may further include a pressing mechanism (not shown), which is connected to the extension arm 310. The pressing mechanism is used to press the extension arm 310 down toward the bridge deck so that the pressure roller 320 can press against the laid portion of the roll material 200. This helps to increase the pressure of the pressure roller 320 on the roll material 200, so that the laid portion of the roll material 200 fits tightly with the bridge deck. This prevents the extension arm 310 from tilting upwards or the pressure roller 320 from not pressing properly due to factors such as the slope of the bridge deck. This ensures that the surface of the rolled material 200 after compaction is flat, free of bubbles and wrinkles, and firmly bonded.

[0050] Optionally, the aforementioned clamping mechanism may be implemented as spring-loaded or controlled by a pneumatic pressure regulating device, etc.

[0051] In some embodiments, the traveling mechanism 100 may include a height adjustment structure (not shown) for adjusting the connection height between the extension arm 310 and the traveling mechanism 100. This allows the user to indirectly adjust the contact effect between the pressure roller 320 and the laying portion of the roll material 200 by adjusting the connection height between the extension arm 310 and the traveling mechanism 100, thereby improving the ease of pre-calibration work for the bridge roof waterproofing roll material laying device 10. Furthermore, adjusting the height of the pressure roller 320 via the height adjustment structure also helps to adapt to the uniformity of the roll material 200 laying under different bridge deck elevation differences.

[0052] Optionally, the aforementioned height adjustment structure may be implemented as a threaded lifting device, but is not limited to.

[0053] In some embodiments, the bridge roof waterproof membrane laying device 10 may further include a traction structure 500, which is connected to the walking mechanism 100. The traction structure 500 is used for users to hold and pull the walking mechanism 100, thereby improving the ease of operation for users and reducing labor intensity.

[0054] Alternatively, the aforementioned traction structure 500 may be implemented as a handle, connecting rod, or pull rope, etc.

[0055] In some embodiments, the bridge roof waterproof membrane laying device 10 may further include a controller (not shown) and a drive source (not shown). The drive source is connected to the walking mechanism 100, and the controller is electrically connected to the drive source. The drive source is used to drive the walking mechanism 100 to move along the bridge deck, and the controller is used to control the movement route of the walking mechanism 100. This helps to realize the automatic operation of the bridge roof waterproof membrane laying device 10, further improves the construction efficiency, and reduces the labor intensity of users.

[0056] Optionally, the aforementioned drive source may be, but is not limited to, an electric motor.

[0057] Optionally, the aforementioned walking mechanism 100 may be implemented as a lightweight steel pipe welded structure, which, while ensuring the structural strength of the walking mechanism 100, helps to improve the lightweight of the walking mechanism 100 and reduce the user's workload.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
