Description

Technical Field

[0001] The utility model belongs to the field of road construction, and more specifically, relates to a paving device for stress absorption stickers. Background Art

[0002] A stress absorption sticker is a composite material specifically designed for road engineering, which integrates multiple functions such as stress dispersion, interlayer bonding, and waterproofing. Its main purpose is to provide an interlayer interface between different layers of the road structure, such as between cement slabs, water-stabilized layers, or asphalt structural layers, that can effectively relieve and inhibit reflection cracks (such as thermal shrinkage cracks, load-induced shear cracks) caused by factors such as temperature changes and vehicle loads. Stress absorption stickers usually have high-strength adhesion performance and can closely adhere to the road surface base layer to form a stable barrier. This barrier can not only disperse and absorb the stress from the road surface base layer, thereby delaying or preventing the cracks from spreading to the upper road surface structure, but also play a waterproofing role to prevent moisture from penetrating into the road surface structure and further protect the stability and durability of the road.

[0003] Currently, the conventional manual paving method for stress absorption stickers is as follows: Workers first unroll the stress absorption roll and place it in a predetermined position. Positioning members (such as wooden squares, stones, etc.) are used to initially fix the roll material to prevent it from moving or slipping. During paving, starting from one end, the stress absorption roll is pushed to roll on the ground to unroll the stress absorption roll, and then the workers adhere the stress absorption sticker to the ground. Although this method is effective, it is relatively time-consuming and labor-intensive, taking a lot of time and effort. Summary of the Utility Model

[0004] In order to improve the problem of time-consuming and labor-intensive manual paving construction, the utility model provides a paving device for stress absorption stickers, and the specific technical solution is as follows:

[0005] A paving device for stress absorption stickers includes a mobile vehicle and a mounting frame. The mounting frame is respectively provided with a positioning member and a unwinding assembly. The positioning member positions the stress absorption sticker roll, and the unwinding assembly unwinds the stress absorption sticker roll; a slot is provided on the mounting frame, and the mobile vehicle has a plug rod, and the plug rod is installed in the slot to drive the mounting frame to move.

[0006] By installing the plug rod in the slot, the mobile vehicle can drive the mounting frame to move. During construction, the stress absorption sticker roll is placed on the mounting frame, and the stress absorption sticker roll is fixed by using the positioning member, and the unwinding assembly unwinds the stress absorption sticker, thus replacing the manual manual unfolding and paving method, improving efficiency and reducing the burden on workers.

[0007] In order to position the stress absorption sticker reel, the positioning member includes two card slots, both of which are provided on the mounting bracket. The card slot has an opening, and the stress absorption sticker reel is inserted into the card slot through the opening. A plug pin is detachably connected to the top wall of the card slot, and the plug pin positions the stress absorption sticker reel in the card slot.

[0008] During installation, the stress absorption sticker reel is inserted into the card slot, and the plug pin is inserted into the card slot to position the stress absorption sticker reel, so that the stress absorption sticker roll can be quickly installed.

[0009] In order to facilitate the stable sliding of the stress absorption sticker reel into the card slot, bearings are provided at both ends of the stress absorption sticker reel. Two snap rings are provided on the outer peripheral wall of the bearing. When the stress absorption sticker reel is inserted into the card slot, the bottom wall of the card slot is located between the two snap rings. By sliding the snap ring along the bottom wall of the card slot, it is convenient for the stress absorption sticker reel to be stably snapped into the card slot.

[0010] In order to prevent the stress absorption sticker reel from squeezing the plug pin when the stress absorption sticker is unfolded, the opening direction of the card slot is set to be opposite to the stress absorption sticker output direction, so as to prevent the stress absorption sticker roll from hitting and deforming the plug pin, resulting in difficult disassembly of the plug pin.

[0011] In order to realize adjusting the tension of the unfolded stress absorption sticker in a timely manner while unfolding the stress absorption sticker, the unwinding assembly includes a magnetic powder brake, which is provided on the mounting bracket. A position sensor is provided on the mounting bracket, and the position sensor is used to detect the number of unwound turns. A transmission member is coaxially provided on the output shaft of the magnetic powder brake;

[0012] A driven gear is provided at the end of the stress absorption sticker roll core shaft, and the transmission member is used to drive the driven gear to rotate.

[0013] The transmission member includes a driving gear coaxially provided on the output shaft of the magnetic powder brake. A rotating gear is rotatably provided on the mounting bracket. The driving gear and the rotating gear are connected by a chain. A linkage gear is coaxially provided on the core shaft of the rotating gear, and the linkage gear and the driven gear are meshed.

[0014] Attach the stress absorption sticker to the ground. The moving vehicle drives the mounting frame, and the stress absorption sticker pulls the stress absorption sticker reel to rotate. By using a position sensor to detect the number of turns of the stress absorption sticker being unwound and wound, and based on the thickness of the stress absorption sticker, the radius of the stress absorption sticker roll can be calculated. That is, for each turn of unwinding, the radius of the remaining roll decreases by the thickness of one layer of material. And since the set tension is constant, the torque can be calculated. The magnetic powder brake controls the torque on the output shaft by adjusting the magnetic field strength, thereby controlling the rotation speed and force of the driving wheel. The driving wheel rotates, drives the driven wheel to rotate through a chain, and then drives the gear to rotate. Finally, the driven gear meshing with the driving gear also starts to rotate. Since the driven gear is coaxial with the core shaft of the roll, the core shaft rotates accordingly, achieving precise control of the process of unwinding and winding the stress absorption sticker, ensuring uniform unwinding of the material and paving quality.

[0015] To improve the stability of the connection between the insertion rod and the insertion slot, the insertion slot and the insertion rod are connected by bolts. The moving vehicle is a forklift, and the insertion rod is a fork.

[0016] Insert the fork of the forklift into the insertion slot and fix it with bolts, so as to stably drive the mounting frame to move.

[0017] To facilitate the handling of the stress absorption sticker reel onto the mounting frame, a vertical frame is provided on the mounting frame. A cross beam is provided on the vertical frame, and an electric hoist is provided on the cross beam.

[0018] Lift the stress absorption sticker reel by the electric hoist, which can replace the manual handling method and reduce the workload of workers.

[0019] Since the end of the cross beam is a free end, to improve the stability of the cross beam, a support frame is provided on the mounting frame. The support frame is arranged opposite to the vertical frame, and the support frame supports the free end of the cross beam.

[0020] Using the support frame to support the free end of the cross beam can enhance the stability of the cross beam.

[0021] The beneficial technical effects of the present utility model:

[0022] 1. In the present utility model, by installing the insertion rod of the moving vehicle in the insertion slot of the mounting frame, the moving vehicle drives the mounting frame to move, and a positioning member is used to fix the stress absorption sticker reel, and then the unwinding component is used for unwinding, which improves the convenience of laying and can also improve the construction efficiency;

[0023] 2. By using precision control components such as magnetic powder brakes and position sensors, it is possible to monitor and control the unwinding speed and force of the stress absorption sticker in real time, ensuring uniform unwinding of the material, avoiding problems such as uneven thickness and wrinkles that may occur during manual laying, and thus improving the construction quality;

[0024] 3. Insert the stress absorption patch reel into the card slot and use a pin for positioning, so that the stress absorption patch reel can be installed conveniently and quickly. Description of the Drawings
