DETAILED DESCRIPTION

[0036] The embodiments of the present application will be further described in conjunction with the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0037] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0038] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0039] In the waterproofing membrane laying, in order to save manpower and material resources and construction time, the paving vehicle can be used to lay the waterproofing membrane, the waterproofing membrane in roll is erected on the paving vehicle, and the waterproofing membrane can be laid on the building surface during the traveling of the paving vehicle. However, due to the uneven force on the two ends of the waterproofing membrane erected on the paving vehicle during the laying process, and the offset or wrinkle of the waterproofing membrane during the stretching process, the waterproofing membrane laid on the ground will also wrinkle, which reduces the laying quality of the waterproofing membrane and even causes the leakage. On the other hand, when a roll of waterproofing membrane is laid, the new waterproofing membrane needs to be rewound on the fixed roller 6 and the movable roller 7. The gap between the fixed roller 6 and the movable roller 7 is small, and the operation space is small, so the roll changing operation is not convenient, which increases the construction time. In order to solve the above problems, the present application provides a waterproofing membrane paving vehicle, as shown in Figure 1 and Figure 2 , which comprises a vehicle body 1, a unwinding device and a paving device arranged on the vehicle body 1. The unwinding device comprises a mounting plate 2 and a support 3, the mounting plate 2 is slidingly arranged on the vehicle body 1, and the support 3 is rotatably arranged on the mounting plate 2. In the present application, the waterproofing membrane in roll to be laid is erected on the support 3 on the vehicle body 1, the waterproofing membrane is stretched from the roll and wound on the fixed roller 6 and the movable roller 7, and finally laid on the surface of the building. Due to the uneven force on the two ends of the roll, the waterproofing membrane will wrinkle or relax when the force is uneven. In order to avoid the above situation, the support 3 and the mounting plate 2 are slidingly arranged on the vehicle body 1. Once the two ends of the roll are unevenly stressed, the support and the mounting plate 2 on which the roll is erected can slide on the vehicle body 1, so that the roll can keep balanced stress. The paving device comprises a fixed frame 4, a rocker arm 5, a fixed roller 6 and a movable roller 7. The fixed frame 4 is fixedly arranged on the vehicle body 1, the fixed roller 6 is rotatably arranged on the fixed frame 4, one end of the rocker arm 5 is rotatably connected with the fixed frame 4, and the other end is connected with the movable roller 7. At the same time, the waterproofing membrane is wound between the fixed roller 6 and the movable roller 7, which can arrange the waterproofing membrane and keep it flat. When the waterproofing membrane needs to be laid or replaced, the movable roller 7 is separated from the fixed roller 6 on the upper part of the fixed frame 4 by rotating the rocker arm 5, then the waterproofing membrane is wound on the movable roller 7 and the fixed roller 6 in turn, and then laid on the ground. Since the distance between the movable roller 7 and the fixed roller 6 on the upper part of the fixed frame 4 is increased after the rocker arm 5 is rotated, the winding of the waterproofing membrane is facilitated. After winding is completed, the rocker arm 5 is turned back to the working position, the waterproofing membrane is compressed between the movable roller 7 and the fixed roller 6 on the upper part of the fixed frame 4, which can reduce the time of replacing the roll, improve the replacement efficiency and facilitate the operation of the construction personnel.

[0052] In the present embodiment, during the waterproofing membrane laying process, the waterproofing membrane is wound on the fixed roller 6 and the movable roller 7, and at the same time, the waterproofing membrane is clamped between the movable roller 7 and the fixed roller 6 located at the upper part of the fixed frame 4. Since the waterproofing membrane has a certain thickness, the distance between the movable roller 7 and the fixed roller 6 is the thickness of the waterproofing membrane. At this time, the first jaw 22 and the second jaw 23 are clamped with each other, preventing the rocker arm 5 from rotating. After a roll of waterproofing membrane is laid, the waterproofing membrane wound on the fixed roller 6 and the movable roller 7 is laid on the ground. At this time, there is no support of the waterproofing membrane between the fixed roller 6 at the upper part of the fixed frame 4 and the movable roller 7, and the movable roller 7 slides downward along the sliding groove 20. The first jaw 22 and the second jaw 23 are separated from each other, and the rocker arm 5 can rotate freely.

When the first jaw 22 and the second jaw 23 come into contact, the first jaw 22 lifts the second jaw 23, causing the second jaw 23 to move upward until the first jaw 22 and the second jaw 23 are clamped with each other. The second jaw 23 is pulled back to the original position by the second return spring 26, and the second jaw 23 abuts against the positioning column 38, completing the clamping of the first jaw 22 and the second jaw 23, preventing the rocker arm 5 from rotating.

[0053] During the laying process of the waterproofing membrane, the paving vehicle needs to move forward, so it is necessary to provide a roller on the paving vehicle. However, during the movement of the paving vehicle, the uneven tension generated by the uneven force on both ends of the waterproofing membrane or the deviation of the route caused by the uneven ground may cause the waterproofing membrane to be laid unevenly. The paving vehicle is generally heavy and difficult to push manually, so it is difficult to correct the deviation of the paving vehicle. However, the paving vehicle in the present application has a steering device that can quickly correct the deviation of the paving vehicle, ensuring the stability and flatness of the laying of the waterproofing membrane.
