Abstract
Description
Technical Field
[0001] This utility model relates to the field of road construction technology, specifically to a road crack-resistant construction device. Background Technology
[0002] Due to the long-term pressure of vehicles, fatigue damage can occur in localized areas of the pavement surface and base layers. When the accumulated damage exceeds the material's crack resistance limit, cracks will initiate from the weak points. Road surface crack-resistant tape can effectively inhibit crack propagation and reflection, prevent rainwater infiltration, avoid further damage, achieve preventative maintenance, and significantly reduce subsequent maintenance costs.
[0003] However, most existing road crack-resistant construction devices are only equipped with simple brushes for cleaning, which cannot effectively remove stubborn impurities and fine dust from the road surface. This will seriously affect the bonding performance between the crack-resistant material and the road surface, reduce the overall strength of the crack-resistant layer, and easily lead to problems such as the crack-resistant material lifting and falling off in the later stages. Utility Model Content
[0004] This utility model provides a road surface crack-resistant construction equipment that can clean the road surface by setting up a sweeping mechanism, and use a brush roller and guide plate to sweep debris into a collection box. At the same time, a dust suction fan is used to suck up and collect fine dust, avoiding secondary scattering and contamination of the road surface after cleaning. This ensures that the road surface is in a clean state before crack-resistant construction, and effectively avoids impurities affecting the bonding strength between the crack-resistant material and the road surface.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0018] The housing of the motor in this device is not shown in the figure.
[0019] Reference Figures 1 to 4 This utility model provides a road surface crack-resistant construction device, which includes a frame 1. The frame 1 is internally rotatably connected to a roll unwinding roller 2 and a guide roller 3. The two ends of the guide roller 3 are fixedly connected to limit plates 4. A cleaning mechanism 5 is provided at the front end of the frame 1. A support 6 is provided at the lower end of the frame 1. An adjustment mechanism 7 is provided at the connection between the frame 1 and the support 6. A pressure roller 10 is rotatably connected to the support 6. A push handle 8 is fixedly connected to one end of the frame 1. A caster wheel 9 is provided at the lower end of the frame 1.
[0020] The cleaning mechanism 5 includes a motor 501, a brush roller 502, a guide plate 503, and a collection box 504. A connecting frame 13 is fixedly connected to the lower end of the frame 1. The motor 501 is fixedly connected to the connecting frame 13. The output end of the motor 501 is fixedly connected to the brush roller 502. The brush roller 502 is rotatably connected to the connecting frame 13. The brush roller 502 is made of metal and has high-strength nylon bristles evenly embedded on its surface. The bristles are of moderate length and have a certain degree of elasticity and hardness.
[0021] The collection box 504 is fixedly connected to the lower end of the frame 1. The guide plate 503 is fixedly connected to one side of the collection box 504. The end of the guide plate 503 away from the collection box 504 is close to the surface of the brush roller 502. The opening of the collection box 504 faces the brush roller 502. A dust suction fan is installed inside the collection box 504. The dust suction fan is fixedly installed on one side inside the collection box 504. The air inlet of the fan faces the opening of the collection box 504. The air outlet extends to the outside of the collection box 504 through a pipe. The fan power supply is connected to the main power supply of the equipment and is equipped with an independent control switch. The adjustment mechanism 7 includes a slide bar 701 and a spring 702. A slide groove 11 is provided at the lower end of the frame 1.
[0022] The slide rod 701 is fixedly connected to the upper end of the bracket 6. The slide groove 11 is slidably connected to the slide rod 701. The spring 702 is sleeved on the surface of the slide rod 701. One end of the spring 702 is fixedly connected to the upper end of the slide rod 701, and the end of the spring 702 away from the slide rod 701 is fixedly connected to the inside of the slide groove 11. When the road surface is uneven, the spring 702 can achieve adaptive adjustment through its own compression or stretching.
[0023] Working principle: During use, the operator opens the box door 12 and places the roll of crack-resistant material onto the unwinding roller 2. The free end of the crack-resistant material is pulled out, and after passing through the guide roller 3, it is laid to the starting position of the road surface to be constructed. Then, the motor 501 and the dust suction fan in the collection box 504 are started. The motor 501 drives the brush roller 502 to rotate at high speed. The nylon bristles on the surface of the brush roller 502 powerfully sweep the road surface, removing dust, gravel, fallen leaves and other debris. Larger debris swept down is guided by the guide plate 503 into the collection box 504 by the rotation of the brush roller 502. At the same time, the dust suction fan creates a negative pressure inside the collection box 504, sucking in the fine dust generated during sweeping, avoiding secondary pollution of the road surface by dust, and completing the pre-treatment cleaning of the road surface.
[0024] Simultaneously, the operator holds the push handle 8 and slowly pushes the equipment along the construction direction. The unwinding roller 2 rotates under the friction between the crack-resistant material and the road surface, smoothly unwinding the roll of crack-resistant material. The crack-resistant material laid on the road surface then enters below the pressure roller 10. Under its own weight and the action of the adjustment mechanism 7, the pressure roller 10 tightly adheres to the surface of the crack-resistant material. When there are small bumps on the road surface, the bumps exert an upward thrust on the pressure roller 10, pushing the pressure roller 10 and the slide bar 701 at the upper end of the support 6 to move upward along the slide groove 11. The spring 702 on the surface of the slide bar 701 is compressed, generating a downward elastic force, which keeps the pressure roller 10 in contact with the raised surface with sufficient pressure. When there is a small depression in the road surface, the spring 702 returns to its original state, pushing the slide bar 701 and the pressure roller 10 downward, ensuring that the pressure roller 10 moves down with the depression area, preventing the pressure roller 10 from separating from the road surface, and also fully compacting the crack-resistant material in the depression area, so that the crack-resistant material is tightly bonded to the road surface, reducing the gap between the material and the road surface, and improving the bonding strength and crack resistance of the crack-resistant material.
[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
