[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figures 1-4 shown, a film laying device for highway engineering includes a first fixing plate 1 and a second fixing plate 2. A fixed rod 3 is fixedly installed at the center position on one side of the first fixing plate 1, and one end of the fixed rod 3 is connected with an extension structure 4. The extension structure 4 includes a plurality of extension rods 5. A screw head 14 is fixedly installed at one end of each extension rod 5, and a screw groove is provided at the other end of each extension rod 5. Adjacent extension rods 5 are threadedly connected through the screw head 14 and the screw groove. An external thread 6 is provided on the outer surface of each extension rod 5. A through hole is provided at the center position of the second fixing plate 2. The extension rod 5 passes through the through hole, and nuts 7 are threadedly connected to both sides of the second fixing plate 2 outside the extension rod 5.

[0025] In this embodiment, two L-shaped support rods are fixedly installed at the rear parts of the first fixing plate 1 and the second fixing plate 2, and a handle rod is sleeved between the ends of the two support rods;

[0026] The two L-shaped rods and the handle rod form an adjustable handle structure, which can adapt to the adjustment of the distance between the first fixing plate 1 and the second fixing plate 2.

[0027] In this embodiment, both the first fixing plate 1 and the second fixing plate 2 are triangularly arranged, and film roll fixing structures are provided at the three corners of both the first fixing plate 1 and the second fixing plate 2. The film roll fixing structure includes an insertion cylinder 8. A limit disk 9 is fixedly installed outside the insertion cylinder 8, and a locking cap 10 is threadedly connected after the insertion cylinder 8 passes through the first fixing plate 1 and the second fixing plate 2;

[0028] The film roll fixing structure can fix the engineering film roll between the first fixing plate 1 and the second fixing plate 2, and since the distance between the first fixing plate 1 and the second fixing plate 2 is adjustable, it can adapt to engineering film rolls of different lengths.

[0029] In this embodiment, an adjusting screw rod 11 is rotatably connected inside the insertion cylinder 8, and a fixed disk 15 is fixedly installed at one end inside the insertion cylinder 8. An adjusting disk 16 is slidably connected inside the insertion cylinder 8. The adjusting disk 16 is threadedly connected to the adjusting screw rod 11. A pressure rod assembly 17 is connected between the fixed disk 15 and the adjusting disk 16;

[0030] By rotating the adjusting screw rod 11, the adjusting disk 16 can be driven to move. During the movement of the adjusting disk 16, the pressure rod assembly 17 can be deformed, so as to be pressed against the inner wall of the engineering film roll to fix it.

[0031] In this embodiment, there are three groups of pressure rod assemblies 17, and a slot is formed on the outer surface of the insertion cylinder 8. All three groups of pressure rod assemblies 17 penetrate through one slot. The pressure rod assembly 17 is composed of three connecting rods. Two of the connecting rods are respectively rotatably connected to the fixed disk 15 and the adjusting disk 16, and the other connecting rod is rotatably connected between the two connecting rods;

[0032] When the adjusting disk 16 moves, the three connecting rods rotate relative to each other. Since the distance between the adjusting disk 16 and the fixed disk 15 increases or decreases, the two inclined connecting rods can be driven to rotate, so as to adjust the expansion degree of the central position connecting rod, and realize the function of pressing and fixing the engineering film roll.

[0033] In this embodiment, locking screw rods 12 are threadedly connected to the inner corner positions of the first fixing plate 1 and the second fixing plate 2. Rubber heads 13 are fixedly installed at the ends of the locking screw rods 12, and the rubber heads 13 are pressed against the outside of the insertion cylinder 8;

[0034] By adjusting the pressure of the rubber head 13 pressed against the outside of the insertion cylinder 8 through the locking screw rod 12, the rotational resistance of the insertion cylinder 8 can be adjusted, and thus the rotational resistance of the engineering film roll can be adjusted.

[0035] It should be noted that the present utility model is a film laying device for highway engineering. When in use, for the length of the engineering film roll, an appropriate number of extension rods 5 are selected. Each extension rod 5 is connected and fixed through a screw head 14 and a screw groove. Finally, the extension rod 5 penetrates through the second fixing plate 2, and then the engineering film roll is sleeved outside the two oppositely positioned insertion cylinders 8. The engineering film roll in the front is used for laying the road, the engineering film roll in the rear is used as a spare and provides pressing for the laid engineering film, and the engineering film roll above is used as a spare and increases the weight. The second fixing plate 2 is clamped and fixed by two nuts 7. Then, the adjusting screw 11 is rotated. The adjusting screw 11 drives the adjusting disc 16 to move. The adjusting disc 16 pushes the pressure rod assembly 17 to deform. The pressure rod assembly 17 presses against the inner wall of the engineering film roll, thereby fixing the engineering film roll. Then, a section of the film of the engineering film roll near the front is drawn out and laid on the road. The staff pushes the entire device through the handle rod. During the process, the engineering film roll rotates through the insertion cylinder 8, and the laying work of the engineering film can be realized. At the same time, the counterweight and pressing functions of the other two engineering film rolls make the laying tightness of the engineering film higher. During the working process, the locking screw 12 is rotated to adjust the pressure between the rubber head 13 and the insertion cylinder 8, thereby adjusting the rotation resistance of the insertion cylinder 8, adjusting the rotation resistance of the engineering film roll, and thus adjusting the tension of the laid engineering film.

[0036] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
