DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-4 , the present utility model provides a technical solution for an efficient film laying device for highway construction: an efficient film laying device for highway construction, including a frame 1 and moving wheels 2 arranged at the front and rear ends of the bottom of the frame 1. A push handle 9 is also arranged at the upper front part of the frame 1. A water tank 3 is installed on the front side of the upper end of the frame 1, and a water outlet pipe 31 is arranged at the bottom of the water tank 3. One end of the water outlet pipe 31 is communicated with a spray pipe 33. A plurality of spray holes are equally spaced on the lower surface of the spray pipe 33. A water pump is arranged inside the water tank 3. One end of the water outlet pipe 31 extends into the water tank 3 and is connected to the water outlet end of the water pump. The other end of the water outlet pipe 31 is connected to the spray pipe 33, and a water valve 32 is also arranged on the water outlet pipe 31. A water injection port is arranged at the top of the water tank 3. Water can be injected into the water tank 3 through the water injection port for storage, which is convenient for use. When laying a film on a highway, by spraying water on the road surface, after the film is laid, the protective film can better adhere to the road surface, ensuring that the film will not be blown up by the wind and affecting the protection of the road surface. When spraying, the water pump is controlled to work through a control box (not shown in the figure) on the frame 1. The water pump conveys water from the water outlet pipe 31 to the spray pipe 33, and then sprays it out to the ground through the spray holes. The spray holes correspond to the ground to ensure the spraying efficiency;

[0028] Such as Figure 5 and 6As shown in the figure, a film releasing roller 4 is installed at the rear side of the upper end of the frame 1, and connecting rods 41 are symmetrically arranged at the lower end of the rear side of the frame 1. Below the space between the two connecting rods 41, two guiding rollers 42 are installed. Near the lower ends of the two connecting rods 41 and between the two guiding rollers 42, a film cutting mechanism 5 is arranged. The film cutting mechanism 5 includes a mounting frame 51 jointly connected to the lower ends of the two connecting rods 41. On one side surface of the mounting frame 51, a driving motor 52 is installed. Inside the mounting frame 51, a driving screw rod 53 is rotatably arranged. One end of the driving screw rod 53 is connected to the output end of the driving motor 52. On both sides of the driving screw rod 53 inside the mounting frame 51, two limiting sliding rods 54 are symmetrically arranged. At the upper end of the mounting frame 51, a moving seat 55 slidably connected to the two limiting sliding rods 54 is arranged. A threaded hole adapted to the driving screw rod 53 is formed in the moving seat 55, and the moving seat 55 is in threaded connection with the driving screw rod 53. The film cutting mechanism 5 further includes an electric push rod 56 installed at the bottom of the moving seat 55. The telescopic end of the electric push rod 56 is connected with a blade 57. The mounting frame 51 is inclined. After the film laying is completed, the driving motor 52 can be controlled to work, so that it drives the driving screw rod 53 to rotate. Under the action of the threaded connection between the driving screw rod 53 and the moving seat 55, the moving seat 55 will be driven to linearly move along the surface of the driving screw rod 53. And under the action of the limiting sliding rods 54, the stability during its movement can be ensured. When the moving seat 55 moves, it can drive the blade 57 to move from one end of the mounting frame 51 to the other end, that is, move from one end of the guiding roller 42 to the other end, so as to facilitate the cutting of the film. Before cutting, first control the electric push rod 56 to drive the blade 57 to extend. When the electric push rod 56 extends in place, at this time, the film between the two guiding rollers 42 is exactly vertically corresponding to the middle of the blade edge of the blade 57. The film can be cut off by the blade 57. When the film does not need to be cut, the electric push rod 56 is in a contracted state, and the blade 57 cannot contact the film;

[0029] As Figure 6 and 7As shown, clamping mechanisms 8 are provided at the bottom ends of the inner side walls of the two connecting rods 41. The two clamping mechanisms 8 are symmetrically arranged. The clamping mechanism 8 includes a static clamping block 81 and a moving clamping block 82 installed at the lower end of the inner side of the connecting rod 41. A fixing block 84 is fixedly installed at the lower end of the inner side wall of the connecting rod 41 corresponding to the moving clamping block 82. Two electric push rods II 85 are symmetrically arranged on one side surface of the fixing block 84. The telescopic ends of the two electric push rods II 85 are perpendicularly fixed to one side surface of the moving clamping block 82 together. Two sliding grooves 83 are symmetrically formed at the lower end of the inner side wall of the connecting rod 41. Two sliding blocks are installed on one side surface of the moving clamping block 82 corresponding to the sliding grooves 83, and the moving clamping block 82 slides in the sliding grooves 83 through the sliding blocks. The static clamping block 81 is fixedly connected to the connecting rod 41. The channel formed between the static clamping block 81 and the moving clamping block 82 is tangent to the surface of the guiding roller 42. The opposite surfaces of the static clamping block 81 and the moving clamping block 82 are flat, and the two corners of the opposite surfaces of the static clamping block 81 and the moving clamping block 82 are arc-shaped corners. When the film needs to be cut, first control the electric push rods II 85 on the two clamping mechanisms 8 to extend synchronously, and use the electric push rods II 85 to push the moving clamping block 82 towards the static clamping block 81, so as to synchronously clamp and fix the two side edges of the film. Then, the film cutting mechanism 5 can be used to cut the film. After cutting, it can avoid the film on the film feeding roller 4 from loosening and becoming messy, and there is no need for the staff to re-thread the film through the guiding roller 42 when laying the film again, which saves time and effort, and can also ensure that the remaining unused film will not become messy.

[0030] Two pressing wheels 6 are symmetrically arranged on the cross beam at the inner side of the rear end of the frame 1, and a distance measuring wheel 7 is also arranged in the middle of the cross beam at the inner side of the rear end of the frame 1. An encoder is connected to the distance measuring wheel 7. The distance measuring wheel 7 and the encoder cooperate to monitor the laying length of the film in real time. The pressing wheels 6 can press the two side plates of the film during film laying to ensure that when the film is laid on the road surface, it can better contact the road surface and improve the adhesion effect between the film and the ground.

[0031] The working principle of the present utility model is as follows: Before laying the film, the film feeding roller 4 is placed on the frame 1. Bearing seats that can be turned over are arranged at both ends of the frame 1 corresponding to the film feeding roller 4, so as to facilitate the installation of the central shaft of the film feeding roller 4 on the bearing seats;

[0032] Then, one end of the film on the film feeding roller 4 is pulled out, passed around the first guiding roller 42, then passed through the channel between the static clamping block 81 and the moving clamping block 82, then passed around the second guiding roller 42, and then passed under the pressing wheel 6, as Figure 4 shown;

[0033] When starting to lay the film, control the water pump to work, and spray the water in the water tank 3 from the spray holes onto the ground, so that the ground is wet, which is convenient for the film laid at the rear end to better adhere to and contact the ground;

[0034] During the film laying operation, the film at the laying position can be measured through the distance measuring wheel 7, so as to conveniently understand the film laying length in real time. At the same time, with the assistance of the pressing wheel 6, it can ensure that the film can be better laid on the road surface. After the laying is completed, by controlling the clamping mechanism 8 to work, the two sides of the film can be synchronously clamped and fixed, and then the film cutting mechanism 5 is used to cut the film, so that the film cutting operation can be realized without manual cutting operation, which saves time and effort. Moreover, after cutting, it can prevent the film on the film release roller 4 from loosening and becoming messy, and there is no need for the staff to re-thread the film through the guide roller 42 when laying the film again, which saves time and effort.

[0035] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of the present technology, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
