Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to an asphalt compacting device for road maintenance. Background Art

[0002] Roads are infrastructure for various trackless vehicles and pedestrians to pass through. According to their usage characteristics, they are divided into highways, urban roads, rural roads, factory and mining roads, forestry roads, test roads, competition roads, automobile test roads, workshop passages, and school roads. In ancient China, there were also post roads. As we all know, roads are prone to damage and potholes during long-term use. In the process of road maintenance and repair, asphalt is often used to fill them. After filling, compaction devices are used to fix them.

[0003] However, during use, the compaction device in the prior art has a certain viscosity of asphalt material. Therefore, when the compaction plate moves vertically back and forth and contacts the asphalt material, the asphalt is easily attached to the compaction plate, resulting in loss of the asphalt material and causing obstacles to road construction. Utility Model Content

[0004] The utility model aims to provide an asphalt compacting device for road maintenance, which has the characteristics of preventing asphalt from adhering to a compacting plate, preventing material loss, being simple to operate, and saving time and effort.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a road maintenance asphalt tamping device, comprising a tamping machine body and a tamping plate installed below the tamping machine body, the left and right side walls of the tamping plate are fixedly connected to two front-to-back distributed and symmetrically arranged right-angle plates, a screw rod is rotatably connected between the two front right-angle plates, and a sliding rod is fixedly connected between the two rear right-angle plates, the outer wall of the sliding rod is slidably connected to a slider, the outer wall of the screw rod is movably connected to a threaded block, the bottom end of the threaded block is fixedly connected to an installation box, the interior of the installation box is rotatably connected to a reel, the outer wall of the reel is wound with a wire rope, and the bottom end of the installation box is provided with a rope outlet, the other end of the wire rope extends to the outside of the installation box through the rope outlet and is fixedly connected to the slider.

[0006] In order to fix the reel, as a preferred road maintenance asphalt compacting device of the utility model, the left side wall of the installation box is fixedly connected with a fixing frame, the outer wall of the fixing frame passes through a movably connected limiting rod, the limiting rod is located on the outer side of the fixing frame and is fixedly connected with a push plate at one end, and one end of the reel extends to the outside of the installation box and is provided with a limiting opening.

[0007] In order to fix the reel, as a preferred embodiment of the road maintenance asphalt compacting device of the utility model, the cross-sections of the limit rod and the limit opening are both regular hexagons that match each other.

[0008] In order to hang the steel wire rope, as a preferred embodiment of the road maintenance asphalt compacting device of the utility model, the outer walls of the two right-angle plates on the left side are fixedly connected with hanging plates.

[0009] In order to drive the screw rod and the reel to rotate, as a preferred road maintenance asphalt compacting device of the utility model, a first motor is installed on the outer wall of the right front right angle plate, and the output end of the first motor is fixedly connected to the screw rod, and a second motor is installed on the outer wall of the installation box, and the output end of the second motor is fixedly connected to the reel.

[0010] In order to reduce the friction on the steel wire rope, as a preferred embodiment of the road maintenance asphalt compacting device of the utility model, both the front and rear sides of the bottom of the compacting plate are smoothly transitioned.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] When the tamping machine body has been working for a long time, if the lower end surface of the tamping plate is covered with a lot of asphalt, the second motor is started to drive the reel to rotate, and the reel reels in the wire rope, thereby tightening the wire rope. At this time, the wire rope is firmly in contact with the lower end surface of the tamping plate. Subsequently, the first motor is started to drive the screw rod to rotate, and the screw rod drives the threaded block on its outer wall to move left and right, thereby driving the installation box to move left and right, so that the wire rope between the slider and the installation box scrapes the lower end surface of the tamping plate, thereby scraping off and cleaning the covered asphalt, ensuring that the asphalt will not adhere to the tamping plate, which can avoid the problem of material loss, and at the same time further enhances the cleanliness of the tamping plate, and is simple to operate, saving time and effort.
