[0002] In the maintenance and construction of airport runways, anti-crack tape is a material used to enhance the surface structure of runways. The laying of anti-crack tape is mainly aimed at cracks on the runway surface, especially cracks caused by factors such as the huge weight of the aircraft, climate change or temperature fluctuations. Repairing cracks with anti-crack tape can improve the compressive and tensile strength of the runway surface layer, disperse the pressure generated by aircraft takeoff and landing, reduce damage to the runway surface, and ensure the flatness and safety of the runway.

[0003] In the existing technology, when the anti-cracking stickers are manually laid without compaction, gaps are formed between the anti-cracking stickers and the foundation, which easily leads to peeling and falling off; when the laying stretch is uneven or not flat, the wrinkled parts become stress concentration points, which are prone to damage and cracking, both of which will reduce the anti-cracking effect and affect the service life.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The first embodiment provided by the present invention is as follows: Figure 1 As shown, a trolley for laying anti-cracking tape includes a bottom horizontal frame 1, a vertical frame 2, a material storage assembly 3, a compacting roller assembly 4, a roller 5, a motor 6, an infrared laser lamp 7 and a handrail 8.

[0025] The bottom cross frame 1 is equipped with directional wheels 11. A material storage assembly 3 is located above one end of the bottom cross frame 1. A compaction roller assembly 4 is connected to the inner side of the other end of the bottom cross frame 1. A roller 5 is hingedly connected to the bottom cross frame 1. A vertical frame 2 is connected to the top of the bottom cross frame 1 near the compaction roller assembly 4. An infrared laser light 7 is mounted on the vertical frame 2, and a handrail 8 is set on the top of the vertical frame 2. Workers push the device to lay the anti-cracking tape along the longitudinal and transverse seams of the old road panel blocks as the centerline. Using this device to lay the anti-cracking tape reduces the labor intensity of construction workers compared to manual laying and improves laying efficiency.

[0026] The second embodiment provided by the present invention: wherein, Figure 2 and Figure 3As shown, the material storage assembly 3 includes a material storage base 31, a support member 32, an extension rod 33, a rotating connector 34, and an anti-cracking patch roll 35. The rotating connectors 34 are provided at both ends of the anti-cracking patch roll 35. The material storage base 31 is located on the bottom horizontal frame 1. The support member 32 is provided on the inner vertical surface of the material storage base 31. The extension rod 33 on the outer side of the rotating connector 34 is clamped above the support member 32. The anti-cracking patch roll 35 equipped with the rotating connector 34 is placed inside the material storage base 31, and the extension rod 33 is mounted on the support member 32. Under the action of the rotating connector 34, the anti-cracking patch on the anti-cracking patch roll 35 can be continuously pulled out.

[0027] like Figure 2 and Figure 4 As shown, the compacting roller assembly 4 includes a compacting roller 41, a bearing 42 and a positioning seat 43. Both ends of the compacting roller 41 are connected to the positioning seat 43 through the bearing 42. The compacting roller 41 can rotate relative to the bottom cross frame 1 through the bearing 42. The anti-cracking sticker pulled out from the storage assembly 3 passes through the bottom of the compacting roller 41. The anti-cracking sticker is divided into a veneer surface and a recovery surface. During the forward movement of the device, the compacting roller 41 rotates continuously as the trolley moves forward, and can stick the veneer surface of the anti-cracking sticker to the cracks on the ground. The compacting roller 41 rolls and squeezes the veneer surface of the anti-cracking sticker between the compacting roller 41 and the ground, so that the veneer surface of the anti-cracking sticker is tightly attached to the ground without leaving any gaps. It is not easy to peel off or fall off in the later stage, thereby increasing the anti-cracking effect.

[0028] like Figure 2 As shown, the body of motor 6 is installed on stand 2, and the output end of motor 6 is connected to drum 5. The recovery surface of the anti-cracking sticker is wound around drum 5 again through the bottom of compacting roller 41. When motor 6 drives drum 5 to rotate, the anti-cracking sticker in storage assembly 3 is wound around drum 5 to ensure that the device is pushed forward. The veneer part of the anti-cracking sticker is continuously taken out and affixed to the ground where the trolley passes, so as to complete the laying of the anti-cracking sticker at the crack. The anti-cracking sticker can be evenly stretched during the transmission process of drum 5, compacting roller assembly 4, and storage assembly 3, so that the flatness is high when it is laid on the ground, improves overall performance and appearance, reduces wrinkles, and can avoid breakage and cracking, thereby ensuring the anti-cracking effect and service life of the anti-cracking sticker. Adjust the rotating speed of motor 6 driving drum 5 to change the speed at which the trolley advances when the anti-cracking sticker is laid.

[0029] like Figure 7 As shown, the infrared laser light 7 is hingedly connected to the stand 2. In the forward direction of the trolley, the infrared laser light 7 can guide the driving direction, which can ensure that the anti-cracking tape is laid in a straight line, improve the construction accuracy, and avoid crooked laying. At the same time, the distance of the infrared laser light 7 projected on the ground can be adjusted by rotating it up and down according to the forward speed, thereby improving the effect of laying the anti-cracking tape.

[0030] like Figure 5 and Figure 6As shown, the compacting roller assembly 4 can also be a structure that is vertically movably connected to the bottom cross frame 1. The compacting roller assembly 4 is vertically movable through the compacting roller height positioning members 12 on the inner side of the bottom cross frame 1 at both ends of the compacting roller assembly 4. The compacting roller height positioning members 12 include clamps 121, springs 122, and shifters 123. The clamps 121 are symmetrically distributed on both sides of the positioning seat 43, and the clamps 121 on one side are connected to the bottom cross frame 1 via the springs 122. The teeth on the circumference of the positioning seat 43 match the teeth of the clamps 121 on both sides. The shifters 123 on both inner sides of the bottom cross frame 1 can be moved away from the other clamp 121, and the positioning seat 43 of the compacting roller assembly 4 is released, which can change the height of the compacting roller assembly 4. After releasing the shifters 123, the positioning seat 43 is positioned again by the teeth. By changing the gap between the compaction roller assembly 4 and the ground in this way, the pressure of the compaction roller 41 rolling the anti-cracking patch can be adjusted, so as to adapt to different ground foundation conditions, further ensure the close fit between the anti-cracking patch and the foundation surface, and avoid hollowing.

[0031] The above are only embodiments of the present invention, and common knowledge such as the specific structures and characteristics of the scheme are not described in detail here. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claim involved.
