Description

Technical Field

[0001] The invention belongs to the technical field of road construction, and in particular relates to a construction device and method for overlapping new and old road surfaces. Background Art

[0002] With the development of social economy, the demand for municipal roads is increasing. The roads built in the early stage can no longer meet the needs of the growth of modern traffic volume and social and economic development. In order to solve this phenomenon, road widening is often used at this stage. During the road widening process, the overlap of the new and old road surfaces needs to be realized by a special overlap construction device to ensure the flatness of the connection between the new and old roads. For example, a new and old road overlap roadbed compaction equipment disclosed in announcement number CN216338864U realizes overlap construction by compacting the connection.

[0003] During construction, the existing overlapping construction device uses its own pressure roller to achieve the overlap of the new and old road surfaces, and at the same time adds structures such as counterweight balls inside the pressure roller. However, the area where the counterweight balls move is within a specified range, so it is difficult to process the structure inside the pressure roller. At the same time, there are a large number of balls and their size is very small. When the space inside for the balls to move is not sealed, the balls are easily discharged, which further increases the manufacturing difficulty. Therefore, there is room for improvement in actual use. Summary of the Invention

[0004] The purpose of the present invention is to provide a construction device and method for overlapping new and old road surfaces, so as to solve the problem in the above-mentioned background technology that the counterweight structure inside the existing pressure roller is cumbersome to install, resulting in greater difficulty in overall processing.

[0008] As a preferred technical solution in the present invention, the outer sleeve of the end shaft is provided with a bearing, and the bearing is slidably engaged in the first ring groove and / or the second ring groove.

[0009] As a preferred technical solution in the present invention, the annular groove 1 and the annular groove 2 are concentric circles, and there is a distance between them, and the distance of the distance is equal to the radius of the counterweight roller.

[0011] As a preferred technical solution in the present invention, a limiting block is welded to the inner wall of the pressure roller, and the end cover is in limited fit with the limiting block.

[0012] As a preferred technical solution in the present invention, a plurality of scrapers are installed on the inner side of the connecting frame. The scrapers are inclined and seamlessly fit the outer surface of the pressure roller.

[0016] Step 2: During processing, the number of counterweight rollers is adjusted according to the actual pressure required for construction. During the adjustment, it is only necessary to place the corresponding number of counterweight rollers in the ring groove 1 and / or the ring groove 2, and then screw the end cover into the interior of the pressure roller until it is supported by the limit block to complete the limit installation;

[0017] Step 3: During processing, the counterweight roller will roll in the ring groove 1 and / or ring groove 2 through the end shaft and bearing under the action of gravity, and will always be at the inner bottom end surface of the pressure roller, thereby increasing the weight of the pressure roller and completing the overlapping and pressurizing work;

[0018] Step 4: During the rolling compaction of the roller, the scraper is used to scrape off the material adhering to the surface of the roller;

[0030] The counterweight assembly is arranged inside the pressure roller 200. The counterweight assembly includes a counterweight roller 203. An annular groove 1 200a and an annular groove 200b are formed on the inner wall of one end of the pressure roller 200. End shafts 203a are fixed to both ends of the counterweight roller 203. The end shaft 203a at one end of the counterweight roller 203 is inserted into the annular groove 1 200a and / or the annular groove 200b. When the pressure roller 200 applies pressure to the new and old road surfaces, the counterweight roller 203 is always located at the bottom end surface of the pressure roller 200 under the action of gravity, thereby increasing the weight of the pressure roller 200 and completing the overlapping pressure work;

[0031] The limiting assembly is arranged inside the pressure roller 200 and abuts against the end shaft 203a at the other end of the counterweight roller 203, thereby achieving installation limitation of the counterweight roller 203.

[0032] In this embodiment, preferably, the outer sleeve of the end shaft 203a is provided with a bearing 202, and the bearing 202 slides into the annular groove 1 200a and / or the annular groove 2 200b, and the counterweight roller 203 is supported by the bearing 202 while ensuring normal rotation.

[0033] In this embodiment, preferably, the annular groove 1 200a and the annular groove 2 200b are concentric circles, which is convenient for processing and subsequent weight adjustment, and there is a distance between the two, and the distance of the distance is equal to the radius of the counterweight roller 203, which facilitates stacking and does not affect the rotation of each counterweight roller 203, thereby achieving weight adjustment.

[0036] In this embodiment, preferably, a plurality of scrapers 102 made of metal are installed on the inner side of the connecting frame 101. The scrapers 102 are inclined and seamlessly fit the outer surface of the pressure roller 200. During use, the scrapers 102 can be used to scrape off the material adhered to the surface of the pressure roller 200, thereby ensuring the quality of subsequent compaction.

[0037] In this embodiment, preferably, a through hole 101a is provided on the surface of the connecting frame 101, and a drain pipe 103 is inserted into the inner side of the through hole 101a. The drain pipe 103 is placed on the top of the scraper 102, which can not only support the drain pipe 103, but also facilitate the subsequent water flow to be transmitted to the pressure roller 200 through the scraper 102. The surface of the drain pipe 103 is evenly provided with drainage holes 103a for water discharge.

[0038] The present invention also discloses a method for using a construction device for splicing new and old pavement, the specific steps of which are as follows:

[0039] Step 1: The new and old road surfaces are paved, and then the compactor is compacted on the new and old road surfaces by the roller 200;

[0040] Step 2: During processing, the number of counterweight rollers 203 is adjusted according to the actual pressure required for construction. During the adjustment, it is only necessary to place the corresponding number of counterweight rollers 203 in the annular groove 1 200a and / or the annular groove 2 200b, and then screw the end cover 201 into the interior of the pressure roller 200 until it is supported by the limit block 200c, thereby completing the limit installation;

[0041] Step 3: During processing, the weighted roller 203 will roll in the annular groove 1 200a and / or the annular groove 2 200b through the end shaft 203a and the bearing 202 under the action of gravity, and will always be located at the inner bottom end surface of the pressure roller 200, thereby increasing the weight of the pressure roller 200 and completing the overlapping and pressurizing work;

[0042] Step 4: During the rolling compaction of the pressure roller 200 , the scraper 102 is used to scrape off the material adhering to the surface of the pressure roller 200 ;
