Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, specifically to a municipal road asphalt pavement maintenance and paving device. Background Technology

[0002] Asphalt pavement refers to various types of road surfaces constructed by incorporating road asphalt materials into mineral materials. Asphalt binders improve the ability of paving aggregates to resist damage to the road surface from traffic and natural factors, resulting in a smooth, dust-free, impermeable, and durable road surface.

[0003] Over time, existing asphalt pavements develop damage or cracks, necessitating maintenance. This maintenance involves removing cracks or damaged sections, filling the resulting depressions with new asphalt, and then paving it. Currently, due to the narrowness of the repair area, paving machines are not readily available, and the asphalt is often spread manually using a scraper. However, this process is cumbersome, asphalt overflows from the filling area, requiring workers to push it back into the depression, thus reducing efficiency. Therefore, we propose a municipal road asphalt pavement maintenance paving device. Utility Model Content

Both ends of the dual-axis motor are fixedly connected with lead screws. The outer end of the lead screw is rotatably connected to the inner wall of the sliding groove. A matching lead screw slider is fitted on the outer wall of the lead screw. The top of the lead screw slider is fixedly connected to the side plate through a connecting plate.

[0009] By adopting the above technical solution, the device is placed in the recessed area by holding the handle, and the dual-axis motor is started to drive the lead screw to rotate, thereby driving the lead screw slider to move and adjust the position of the side plates on both sides so that they are placed on both sides of the recessed area, and the distance between the two side plates is greater than the width of the recessed area. Then, asphalt is placed in the recessed area, and the device is pushed to spread the asphalt. During the spreading process, the side plates on both sides of the recessed area prevent the overflowing asphalt. Periodically starting the dual-axis motor can drive the two side plates to move inward, thereby pushing the overflowing asphalt into the recessed area. This eliminates the need for workers to manually push the overflowing asphalt, which improves the convenience of operation and thus improves the efficiency of spreading.

[0010] In a preferred embodiment of this utility model, the handle includes a fixed rod and a sleeve. The fixed rod is fixedly connected to an end plate. An insert rod is fixedly connected to the outer end of the fixed rod. The insert rod is inserted into the inner cavity of the sleeve. A bolt passes through the outer wall of the sleeve. The outer wall of the insert rod has multiple evenly distributed threaded holes. The bolt engages with the corresponding threaded holes.

[0015] By adopting the above technical solution, the fit between the side plate and the end plate is guaranteed, which helps to avoid the situation where asphalt overflows from the gap.

[0016] In a preferred embodiment of this utility model, the bottom of the side plate and the bottom plane of the end plate are flush.

[0017] By adopting the above technical solution, the adhesion between the bottom of the side plate and end plate and the asphalt ground is guaranteed to be consistent.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This application discloses a municipal road asphalt pavement maintenance paving device. The side plates of the paving assembly can move closer or further apart under the drive of a dual-shaft motor and a lead screw, allowing the device to adapt to paving operations in depressions of varying widths, thus improving adaptability. During paving, the side plates are positioned on either side of the depression to prevent overflowing asphalt. Periodic activation of the dual-shaft motor moves the side plates inward, pushing the overflowing asphalt into the depression, eliminating the need for manual pushing of the overflowing asphalt and improving operational convenience and paving efficiency.

[0020] The length of the handle can be adjusted by inserting a rod into the fixed rod and the sleeve, and by using bolts to connect the threaded holes at different positions on the sleeve and the rod. This improves the device's adaptability to different heights of workers. Attached Figure Description
