Description

Technical Field

[0001] The utility model relates to the technical field of pavers, in particular to a pavers for thin-layer overlays. Background Art

[0002] A paver is a construction equipment mainly used for paving various materials on the base and surface layers of highways. The paving work is completed by the cooperation of various systems, mainly including a walking system, a hydraulic system, a material distribution system, etc. During road maintenance, an existing paver needs to spread a layer of asphalt protection on the basis of the original thin-layer overlay road. When in use, the asphalt material is transported to the front end, and when the paver is pulled and moved, the asphalt material is rolled and compacted by a rolling mechanism. However, in actual operation, there is often a small amount of asphalt material on both sides of the rolling mechanism that has not been rolled and compacted, and is set in a certain convexity. At this time, manual labor is required on both sides of the road to use tools such as shovels to remove the missed asphalt materials on both sides. This operation not only causes a waste of resources, but also a waste of manpower. In addition, the heated asphalt material emits harmful substances, and long-term inhalation by personnel may affect their health. Therefore, a paver for thin-layer overlay is proposed to address the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide a paver for thin-layer overlay to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

However, in actual operation, there is often a small amount of asphalt material on both sides of the rolling mechanism that has not been rolled and compacted, and is set in a certain convexity. At this time, it is necessary for people on both sides of the road to use tools such as shovels to remove the missed asphalt materials on both sides. This operation not only causes waste of resources, but also wastes manpower. In addition, the heated asphalt material emits harmful substances, and long-term inhalation by personnel may affect their health. When the device is in use, an external power supply is connected, and the adjustment frame is driven to rotate by starting the hydraulic rod to adjust the position of the adjustment frame. Then, when paving, the threaded shaft can be driven to rotate by starting the motor, so that the threaded sleeve moves, and the threaded sleeve drives the buffer body to move, and finally drives the moving rod and the fixed sleeve to move. The fixed sleeve and the rotating roller are in close contact with the asphalt pavement, and the fixed sleeve and the rotating roller cooperate to automatically roll a small amount of leaked asphalt material. This does not require manual participation, and after use, the hydraulic rod can drive the adjustment frame to automatically reset to avoid protruding to both sides and affecting the movement of the equipment.

[0013] During actual use, the fixed plate can be used to squeeze the spring to drive the moving plate at the bottom to squeeze the moving rod to move. At this time, it is used to drive the moving rod and the fixed sleeve to move downward. This setting has a certain buffering effect through the sliding rod, and has the purpose of automatic adjustment for different protruding leaked asphalt materials, thereby avoiding damage to the equipment due to violent collision. The set sliding rod and sliding plate can ensure the stable up and down movement of the moving plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] When the utility model is in use, the hydraulic rod is started to drive the adjustment frame to rotate, so as to adjust the orientation of the adjustment frame. Then, when paving is performed, the motor is started to drive the threaded shaft to rotate, so that the threaded sleeve moves, and the threaded sleeve drives the buffer body to move, and finally drives the moving rod and the fixed sleeve to move.

[0026] A paver for thin-layer overlay, comprising a paver 1 and an edge and corner scraping mechanism 2.

[0027] The two corners of the paving frame of the paving machine 1 are both installed with edge and corner scraping mechanisms 2, and the tops of the edge and corner scraping mechanisms 2 are rotatably connected with rotating rods 4, and the tops of the rotating rods 4 are fixedly connected to the paving frame of the paving machine 1;

[0028] The outer sides of the above-mentioned edge and corner scraping mechanism 2 are rotatably connected with a hydraulic rod 3, and the other end of the hydraulic rod 3 is rotatably connected to the paver 1;

[0029] The above-mentioned edge and corner scraping mechanism 2 includes an adjusting frame 201 and a buffer body 205. One side of the above-mentioned adjusting frame 201 is rotatably connected to the hydraulic rod 3, and the top of the above-mentioned adjusting frame 201 is rotatably connected to the rotating rod 4. The inside of the above-mentioned adjusting frame 201 is fixedly connected with a motor 202, and the end of the main shaft of the motor 202 is fixedly connected with a threaded shaft 203, the outer side of the above-mentioned threaded shaft 203 is spirally connected with a threaded sleeve 204, and the bottom of the above-mentioned threaded sleeve 204 is fixedly connected with a buffer body 205. The outer side of the above-mentioned buffer body 205 is slidably connected to the adjusting frame 201, and the bottom of the buffer body 205 is fixedly connected with a moving rod 206, the bottom of the above-mentioned moving rod 206 is fixedly connected with a transversely arranged fixed sleeve 207, and the outer side of the fixed sleeve 207 is rotatably connected with a rotating roller 208.

[0030] The fixing sleeve 207 and the rotating roller 208 are both arranged to be inclined in the horizontal direction, and both ends of the fixing sleeve 207 are provided with extension rods extending outwards, and the extension rods extend into the interior of the rotating roller 208 and are rotatably connected to the rotating roller 208 .

[0031] When the existing paver is in use, the asphalt material is transported to the front end, and when the paver is pulled and moved, the asphalt material is rolled and compacted by the rolling mechanism. However, in actual operation, there is often a small amount of asphalt material on both sides of the rolling mechanism that has not been rolled and compacted, and is set in a certain convexity. At this time, it is necessary for people on both sides of the road to use tools such as shovels to remove the missed asphalt materials on both sides. This operation not only causes a waste of resources, but also wastes manpower. In addition, the heated asphalt material emits harmful substances, and long-term inhalation by personnel may affect their health. When the device is used, an external power supply is connected, and the hydraulic rod 3 is started to drive the adjustment frame 201 Rotation is used to adjust the orientation of the adjustment frame 201. Then, during paving work, the threaded shaft 203 can be driven to rotate by starting the motor 202, so that the threaded sleeve 204 moves, and the threaded sleeve 204 drives the buffer body 205 to move, and finally drives the moving rod 206 and the fixed sleeve 207 to move.

[0036] During actual use, the fixed plate 2051 can squeeze the spring 2054 to drive the movable plate 2055 at the bottom to squeeze the movable rod 206 to move, and at this time it is used to drive the movable rod 206 and the fixed sleeve 207 to move downward. This setting has a certain buffering effect through the sliding rod 2052, and has the purpose of automatic adjustment for different protruding leaked asphalt materials, thereby avoiding damage to the equipment due to violent collision.
