Description

Technical Field

[0001] The utility model relates to the field of film laying devices, in particular to a film laying device for highway engineering construction. Background Art

[0002] During the construction of concrete roads, after the concrete is poured, it is necessary to lay the membrane in time. Laying the membrane can prevent the concrete moisture from evaporating too quickly and causing cracks, and can also isolate foreign matter. In order to lay the membrane on the road surface, a membrane laying device is required.

[0003] The patent with patent publication number CN216074652U discloses a film laying device for highway engineering construction, which includes components such as a base, a pressing plate, a fixing frame, a spring and a rotating shaft. When in use, as the base moves, the film cylinder will continuously rotate on the outer surface of the rotating shaft, thereby laying the film on the construction site. When encountering roads of different widths, the pressing plate can be pressed by hand to drive the inner bottom surface of the rotating shaft to compress the spring until the other end of the rotating shaft is taken out from the inside of the fixing hole. At this time, the entire rotating shaft can be slowly removed from between the two fixing frames, and the film cylinder can be removed from the outer surface of the rotating shaft and replaced with a new type of film cylinder. Although this method can replace films of different widths, since there is only one film cylinder, when the width of the film is smaller than the width of the road surface, it is still necessary to repeat the film laying multiple times to cover the road surface, which is time-consuming and labor-intensive as a whole. Therefore, a film laying device for highway engineering construction that can flexibly cope with roads of different widths is now developed. Utility Model Content

[0004] In order to overcome the disadvantage that the current film laying device is time-consuming and labor-intensive to lay film on a wider road surface due to its fixed size, the utility model provides a film laying device for highway engineering construction that can flexibly cope with highways of different widths.

[0006] Furthermore, the replacement component includes a disassembly plate, which is slidably connected to the first placement rack and the second placement rack respectively. The first placement rack and the second placement rack are both clamped with limit rods, and the limit rods are respectively plugged into and matched with the adjacent disassembly plates.

[0007] Furthermore, it also includes rotating rods, one of which is rotatably connected to the first placement rack, and the other rotating rods are rotatably connected to the second placement rack, and the rotating rods are fixedly connected to the heating wires.

[0010] Furthermore, the vehicle also includes a guide frame, which is rotatably connected to the vehicle frame, and symmetrically distributed torsion springs are wound between the guide frame and the vehicle frame.

[0011] The beneficial effects of the utility model are:

[0012] The utility model can adjust the width of the film laid by the device by moving the sliding clamp rod to make the second placement frame extend, so as to adapt to road surfaces with different widths.

DETAILED DESCRIPTION

[0026] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Embodiment 1: A film laying device for highway engineering construction, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a frame 1, the front part of the frame 1 is rotatably connected to a roller 2, the rear part of the frame 1 is fixedly connected to a first placement rack 3, the first placement rack 3 is provided with a replacement component, and also includes a guide plate 6, the guide plate 6 is fixedly connected to the upper rear part of the frame 1, and two sliding clamping rods 7 distributed up and down are slidably connected to the guide plate 6, and the sliding clamping rods 7 are each provided with a plurality of limiting holes distributed at equal intervals, and the upper part of the guide plate 6 is slidably connected to two clamping blocks 71, and the clamping blocks 71 are plugged into the limiting holes on the adjacent sliding clamping rods 7, and the rear part of the sliding clamping rods 7 is fixedly connected to a second placement rack 72, and the second placement rack 72 is also provided with a replacement component.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the replacement component includes a disassembly plate 4, and the number of the disassembly plates 4 is three. The three disassembly plates 4 are respectively slidably connected to the lower left part of the first placement rack 3 and the lower left part of the two second placement racks 72. The left parts of the first placement rack 3 and the second placement rack 72 are both clamped with the limiting clamp rod 41, and the limiting clamp rod 41 is respectively plugged into and matched with the adjacent disassembly plates 4.

[0029] The clamping block 71 is then moved back to the position where the second support frame 72 is located, and the clamping block 71 is moved back to the position where the second support frame 72 is located. The clamping block 71 is then removed from the sliding clamping rod 7 and the second rack 72 is moved in the reverse direction to reset it, thereby making the second rack 72 move in the reverse direction and reset it, and then the clamping block 71 is inserted back into the sliding clamping rod 7, and the second rack 72 is extended by moving the sliding clamping rod 7, so that the width of the film that can be laid by the device can be adjusted, so that it can adapt to road surfaces of different widths.

[0030] Embodiment 2: Based on embodiment 1, Figure 2 , Figure 5 and Figure 6 As shown, it also includes a rotating rod 8, the number of which is three, one of which is rotatably connected to the right side of the first placement rack 3, and the other two rotating rods 8 are rotatably connected to the right sides of the two second placement racks 72 respectively, and the rotating rods 8 are all fixedly connected with electric heating wires 9.

[0031] In order to facilitate the cutting of the film, when the film needs to be cut, the operator can turn on the heating wire 9 to make the heating wire 9 heat up, and then manually rotate the rotating rod 8 corresponding to the film to be cut, so that the rotating rod 8 drives the heating wire 9 to rotate. At this time, the heating wire 9 can cut the film, and then turn off the heating wire 9, manually rotate the rotating rod 8 in the opposite direction, so that the rotating rod 8 and the heating wire 9 are reset. In this way, there is no need to go elsewhere to get the film cutting tool, which is more convenient to use, and the incision of the film can be neater.

[0032] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, it also includes a placement frame 11, the number of the placement frames 11 is two, the two placement frames 11 are respectively fixed to the two second placement racks 72, the lower side of the placement frames 11 away from each other are fixed with electric push rods 13, the telescopic rods of the electric push rods 13 are fixed with baffles 12, the baffles 12 are slidably connected to the adjacent placement frames 11, and the baffles 12 are located at the bottom of the adjacent placement frames 11.

[0033] In order to make the position of the laid film more stable, some sand and gravel can be placed in the placement frame 11. At this time, the sand and gravel are blocked by the baffle 12 and cannot fall. During the film laying process, the electric push rod 13 can be turned on. Driven by the telescopic rod of the electric push rod 13, the baffle 12 gradually moves backwards. At this time, a small opening appears at the bottom of the placement frame 11. Sand and gravel will leak out from this opening and fall on the film. Because the edge of the film is pressed by a heavy object, the overall position of the film can be more stable. After the film laying is completed, the baffle 12 is driven by the electric push rod 13 to move forward and reset, and then the electric push rod 13 can be closed.

[0034] like Figure 1 , Figure 2 and Fig. 9 As shown, the vehicle frame 1 further includes a guide frame 14 rotatably connected to the front upper portion of the vehicle frame 1 , and torsion springs 15 are wound between the left and right sides of the guide frame 14 and the vehicle frame 1 .

[0035] Since there may be some stones on the rolling path of the roller 2, these stones will affect the flatness of the road surface, so the stones can be collected by the guide frame 14. As the frame 1 moves, the guide frame 14 will also move. When the guide frame 14 contacts the stones, the stones will enter the guide frame 14. After the film is laid, the stones in the guide frame 14 can be taken out. The purpose of setting the torsion spring 15 is to make the front lower part of the guide frame 14 close to the road surface. When the road surface has a certain slope, the torsion spring 15 can be twisted to keep the guide frame 14 close to the road surface.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, a fan 5 is also included, and the fan 5 is fixedly connected to the upper rear part of the first placement rack 3.

[0037] In order to make the film fit the road surface better, the fan 5 can be turned on to blow air to the laid film, so that the film can fit the road surface better. After the film laying is completed, the fan 5 can be turned off.

[0038] It should be understood that the above description is only for exemplary purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
