Description

Technical Field

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

[0002] Some road surfaces are built with cement. Cement requires appropriate moisture to solidify and react with moisture to continuously increase the hardness of the concrete. After the highway is poured, a moisturizing film needs to be laid on the surface of the highway to prevent moisture evaporation. The moisturizing film prevents moisture from evaporating too quickly, which will lead to the solidification of the concrete, cracking, peeling, etc., affecting the strength of the concrete.

[0003] In the prior art, there is a process of spreading a certain amount of sand and gravel on the moisturizing film after paving the moisturizing film. Its main purpose is to prevent the external wind from acting on the moisturizing film and causing the moisturizing film to separate from the ground. However, this method still needs to remove the sand and gravel on the moisturizing film after the ground is formed, which increases the workload of subsequent construction. Utility Model Content

[0034] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0035] See also Figure 1 to Figure 6 In an embodiment of the utility model, a highway engineering film laying device includes a truss 1, on which a winding roller 19, a guide roller 21 and a paving rod 22 are arranged. The moisturizing film wound on the winding roller 19 is pulled to the paving rod 22 through the guide roller 21 and laid on the ground, wherein two groups of brackets 20 are symmetrically arranged on the truss 1, and a groove for the winding roller 19 rotating shaft to be placed is arranged on the bracket 20, and a guiding inclined surface 2001 is formed on the inner side of the top of the groove. When in use, the winding roller 19 can rotate in the groove by its own weight, and at the same time, under the action of the guiding inclined surface 2001, the winding roller 19 can be more convenient in the installation process, and has a certain anti-fool effect;

[0036] It also includes: a roller 18, a transverse movement component, a lifting component and a power component, so that when the roller 18 moves, the moisturizing film can be rolled unidirectionally, which can improve the fit between the moisturizing film and the ground on the one hand, and avoid wrinkles in the moisturizing film when the roller 18 moves in the opposite direction on the other hand.

[0037] Specifically, two groups of rollers 18 are provided and connected to the truss 1. The two groups of rollers 18 move away from each other so that the moisturizing film laid on the ground can fit the ground;

[0038] The power assembly is arranged on the truss 1, and the power assembly can alternately drive the truss 1 and the transverse movement assembly to move. The power assembly includes a driving device 2 fixedly mounted on the truss 1, and the output shaft of the driving device 2 is connected to the Maltese cross movement structure arranged on the truss 1;

[0039] The Maltese cross movement structure includes a driving wheel 3 rotatably mounted on the truss 1 and connected to the output shaft of the driving device 2, and the driving wheel 3 is adapted to the first driven wheel 4 and the second driven wheel 7 arranged on the truss 1;

[0040] The first driven wheel 4 is connected to a driving wheel 6 arranged at the bottom of the truss 1 through a belt 5, and the second driven wheel 7 is connected to the transverse movement assembly.

[0041] When in use, the drive device 2 is controlled to work. At this time, the output shaft of the drive device 2 will drive the connected driving wheel 3 to rotate, and alternately drive the No. 1 driven wheel 4 and the No. 2 driven wheel 7 adapted to the driving wheel 3 to rotate. Specifically, when the No. 1 driven wheel 4 rotates in coordination with the driving wheel 3, the No. 2 driven wheel 7 is in a locked state, and when the No. 2 driven wheel 7 rotates in coordination with the driving wheel 3, the No. 1 driven wheel 4 is in a locked state. Based on this, on the one hand, the lateral movement of the truss 1 and the flattening of the roller 18 can alternately move, so that the moisturizing film is evenly in contact with the ground. On the other hand, the lateral movement of the truss 1 and the roller 18 can alternately utilize the output power of the drive device 2, which can effectively avoid excessive load on the drive device 2 and improve the durability of the drive device 2.

[0042] See also Figure 1 , Figure 5 , Figure 6 , the transverse movement assembly is arranged on the truss 1, the transverse movement assembly is connected to the roller 18, the transverse movement assembly includes a rotating shaft 9 rotatably mounted on the truss 1, the rotating shaft 9 is sleeved with a follower sleeve 10 that is slidably fitted therewith, the follower sleeve 10 and the rotating shaft 9 are connected via a keyway kit, the keyway kit includes a convex circle 1001 arranged on the inner wall of the follower sleeve 10 and a closed groove 901 arranged on the rotating shaft 9, the convex circle 1001 is slidably fitted with the closed groove 901;

[0043] The truss 1 is also provided with a side plate 11, and the guide portion 1002 provided on the follower sleeve 10 can slide in the guide groove 1101 on the side plate 11;

[0044] The rotating shaft 9 is connected to the second driven wheel 7 via a bevel gear set 8, wherein the bevel gear set 8 includes a first bevel gear and a second bevel gear rotatably mounted on the truss 1 and meshing with each other, the first bevel gear is coaxially fixedly connected to the second driven wheel 7, and the second bevel gear is coaxially fixedly connected to the rotating shaft 9;

[0045] The transverse movement assembly further includes a transverse plate 13 disposed on the truss 1, the transverse plate 13 is provided with a slide groove 1301, two sliders 14 are symmetrically slidably installed in the slide groove 1301, and the sliders 14 are connected to the follower sleeve 10 through a connecting rod 12;

[0046] The slider 14 is connected to the lifting assembly.

[0047] When the No. 2 driven wheel 7 rotates, the rotating shaft 9 will be driven to rotate through the No. 1 bevel gear and the No. 2 bevel gear. At this time, the follower sleeve 10 mounted on the rotating shaft 9 can be lifted and lowered reciprocatingly along the length direction of the guide portion 1002 with the cooperation of the closed groove 901 and the convex circle 1001, and the two sliders 14 are pulled closer to or away from each other through the connecting rod 12. At this time, the two sliders 14 can respectively drive the two rollers 18 to reciprocate once along the length direction of the truss 1, and the moisturizing film laid on the ground is flattened for a second time, thereby improving the fit between the moisturizing film and the ground.

[0048] Through the above-mentioned arrangement, in the process of spreading the moisturizing film, the two rollers 18 can perform a reciprocating motion along the width direction of the truss 1, and flatten the moisturizing film laid on the ground for a second time, thereby improving the degree of fit between the moisturizing film and the ground, avoiding the separation of the moisturizing film from the ground under the action of external wind, and improving the stability of the moisturizing film after bonding.

[0049] It should be noted that, within one rotation cycle of the second driven wheel 7 , the rotating shaft 9 will rotate one circle, and the follower sleeve 10 can perform an action of first descending and then ascending.

[0050] See also Figure 1 , Figure 6 The lifting assembly is connected to the transverse moving assembly and the roller 18, and the lifting assembly can separate the roller 18 from the ground when the two groups of rollers 18 move towards each other;

[0051] The lifting assembly includes a follower frame 15 fixedly connected to the slider 14, an electric telescopic rod 16 is fixed to the follower frame 15, an action end of the electric telescopic rod 16 is connected to a connecting frame 17 sliding on the follower frame 15, and the connecting frame 17 is rotatably connected to the roller 18.

[0052] When the two rollers 18 are in a state of approaching each other, a distance sensor (not shown in the figure) arranged therebetween will control the movement of the electric telescopic rod 16 so that the two rollers 18 can fit the ground, and then the two rollers 18 will move away from each other to flatten the moisturizing film for a second time along the width direction of the truss 1. When the two rollers 18 move to the farthest distance from each other, the distance sensor will control the movement of the electric telescopic rod 16 again to separate the rollers 18 from the ground, that is, when the two rollers 18 move towards each other, the two rollers 18 will remain separated from the ground, thereby avoiding wrinkles in the moisturizing film due to the squeezing of the rollers 18 when the rollers 18 move in the opposite direction.

[0053] Through the above arrangement, when the roller 18 moves, the moisturizing film can be rolled unidirectionally, which can improve the fit between the moisturizing film and the ground on the one hand, and avoid wrinkles in the moisturizing film when the roller 18 moves in the opposite direction on the other hand.
