Description

Technical Field

[0001] This utility model relates to the field of asphalt road compaction technology, and in particular to an asphalt pavement corner compactor. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials with mineral materials. Asphalt binder improves the ability of paving aggregates to resist damage to the pavement from traffic and natural factors, making the pavement smooth, dust-free, impermeable, and durable. Therefore, asphalt pavement is one of the most widely used high-grade pavements in road construction. During the construction of asphalt pavement, compaction equipment is required for compaction. Generally, large compaction equipment is used, but it is not suitable for compaction of the edges and corners of asphalt pavement.

[0003] In the prior art, such as Chinese Patent Publication No. CN217781643U, an asphalt pavement corner compactor is disclosed. It includes a compactor body, which includes a compaction roller body, a corner trimming ring, a road leveling ring, and a main roller shaft. The corner trimming ring and the road leveling ring are respectively spirally installed at both ends of the compaction roller body. The compaction roller body includes a main roller body, a first spiral mounting head, and a second spiral mounting head. At the same time, both ends of the corner trimming ring are provided with vertical trimming end faces. By combining the compaction roller body with the corner trimming ring, the overall structure can realize the asphalt pavement corner compaction operation and achieve vertical trimming of the end faces while compacting. This can effectively ensure that the corner end faces are flat and beautiful after compaction. At the same time, the road trimming ring can ensure that the outer surface of the compaction roller body at the top of the asphalt pavement corner is flat, thus resulting in a high degree of flatness of the corner after compaction.

[0004] Although the compactor in the aforementioned patent can compact and trim the edges and corners of asphalt pavement, in the prior art, the compactors used for trimming the edges and corners of asphalt pavement are usually simple in design, mainly relying on the rolling of the pressure roller on the edges and corners of the asphalt pavement for compaction. However, if the pressure roller is not heavy enough, it will easily cause poor compaction effect. If the pressure roller is too heavy, it will require a lot of force to push, which is inconvenient to use. Therefore, in order to address the above problems, we propose a new type of asphalt pavement edge and corner compactor. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of existing compactors used for trimming the edges and corners of asphalt pavements. These compactors are usually simple in design and mainly rely on rollers to roll and compact the edges and corners of the asphalt pavement. However, if the rollers are not heavy enough, the compaction effect will be poor. If the rollers are too heavy, they require a lot of effort to push and are inconvenient to use. Therefore, this utility model proposes an asphalt pavement edge and corner compactor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an asphalt pavement corner compactor, comprising a frame, a handle symmetrically arranged on the top of the frame near the rear surface, an electric telescopic rod fixedly installed on the bottom of the frame near the rear surface, a first mounting frame fixedly installed on the bottom of the frame near the front surface by bolts, a hexagonal groove provided on one side of the outer surface of the first mounting frame near the bottom, a compaction component installed between the inner walls of the first mounting frame, and a power component located at the bottom of the electric telescopic rod.

[0007] Furthermore, the compaction assembly includes a pressure roller, the inside of which is provided with a bearing, and a long screw is provided through the inner wall of the bearing, the outer surface of which slides through the outer surface of the first mounting frame.

[0008] Furthermore, a nut is threaded onto the outer surface of the long screw near the end face, and the nut engages with a hexagonal groove.

[0009] Furthermore, the power assembly includes a second mounting bracket, which is fixedly mounted on the bottom of the electric telescopic rod. A drive motor is fixedly mounted on the top of the second mounting bracket near its edge. A first pulley is rotatably connected to one side of the outer surface of the second mounting bracket, and a second pulley is rotatably connected to one side of the outer surface of the second mounting bracket above the first pulley. The output end of the drive motor is fixedly connected to the outer surface of the second pulley.

[0010] Furthermore, a transmission belt is provided between the outer surfaces of the first pulley and the second pulley, and a rotating shaft is rotatably connected between the inner walls of the second mounting bracket, with a power roller fixedly connected to the outer surface of the rotating shaft.

[0011] Furthermore, one end of the rotating shaft slides through the outer surface of the second mounting bracket and extends to the outside, and the end face of the rotating shaft is fixedly connected to the center of the outer surface of the first pulley.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by holding the handle and pushing the device, the pressure roller is moved to the corner of the asphalt road to compact the corner. When pushing the device, the electric telescopic rod is activated to lower the power roller in the power assembly to a suitable position after it is in contact with the ground. Then, the drive motor is activated to drive the second pulley to rotate, which in turn drives the first pulley and the shaft to rotate, thereby driving the power roller to rotate. After the power roller is in contact with the ground, it rotates and plays the role of pushing the device. This solves the problem of the pressure roller being too heavy to push. By using a heavier pressure roller, the compaction effect is improved, and it is more labor-saving and convenient to use.

[0014] 2. In this utility model, the bearing installed between the pressure roller and the long screw reduces the friction between them, facilitates the rotation of the pressure roller, and further saves effort. The detachable nut and long screw facilitate the disassembly and assembly of the pressure roller, thereby making it easier to replace and maintain the pressure roller in the future, and improving its practicality.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figures 1-4As shown, this utility model provides an asphalt pavement corner compactor, including a device frame 1. Handles 11 are symmetrically arranged on the top of the device frame 1 near the rear surface. An electric telescopic rod 2 is fixedly installed on the bottom of the device frame 1 near the rear surface. A first mounting frame 21 is fixedly installed on the bottom of the device frame 1 near the front surface by bolts. A hexagonal groove 22 is provided on one side of the outer surface of the first mounting frame 21 near the bottom. A compaction component 3 is installed between the inner walls of the first mounting frame 21. A power component 4 is located at the bottom of the electric telescopic rod 2. The compaction component 3 includes a pressure roller 301. A bearing 302 is provided inside the pressure roller 301. A long screw 303 is passed through the inner walls of the bearing 302. The outer surface of the long screw 303 slides through the outer surface of the first mounting frame 21. A nut 304 is threadedly connected to the outer surface of the long screw 303 near its end face. The nut 304 cooperates with the hexagonal groove 22.

[0023] The overall effect of Embodiment 1 is that the length of the pressure roller 301 in this device is 50-60cm. The pressure roller 301 is made of manganese steel, or can be replaced with other corrosion-resistant, wear-resistant and heavier materials, which can be selected according to the actual situation. When using it, by holding the handle 11, the device is pushed to move the pressure roller 301 to the corner of the asphalt road to compact the corner. When pushing the device, the electric telescopic rod 2 is activated to drive the power roller 403 in the power assembly 4 to descend to a suitable position after it is in contact with the ground. Then, the drive motor 405 is activated to drive the second pulley 406 to rotate, which, together with the transmission belt 407, drives the first pulley 404 and the rotating shaft 402 to rotate, thereby driving the power roller 403 to rotate. After the power roller 403 is in contact with the ground, it rotates and plays the role of pushing the device. This solves the problem that the pressure roller 301 is too heavy to push. By using a heavier pressure roller 301, the compaction effect is improved, and it is more labor-saving and convenient to use.

[0024] Example 2, as Figures 1-4As shown, the power assembly 4 includes a second mounting bracket 401, which is fixedly mounted on the bottom of the electric telescopic rod 2. A drive motor 405 is fixedly mounted on the top of the second mounting bracket 401 near its edge. A first pulley 404 is rotatably connected to one side of the outer surface of the second mounting bracket 401. A second pulley 406 is rotatably connected to one side of the outer surface of the second mounting bracket 401 above the first pulley 404. The output end of the drive motor 405 is fixedly connected to the outer surface of the second pulley 406. A transmission belt 407 is provided between the outer surfaces of the first pulley 404 and the second pulley 406. A rotating shaft 402 is rotatably connected between the inner walls of the second mounting bracket 401. A power roller 403 is fixedly connected to the outer surface of the rotating shaft 402. One end of the rotating shaft 402 slides through the outer surface of the second mounting bracket 401 and extends to the outside. The end face of the rotating shaft 402 is fixedly connected to the center of the outer surface of the first pulley 404.

[0025] The overall effect of Embodiment 2 is that by setting a bearing 302 between the pressure roller 301 and the long screw 303, the friction between the pressure roller 301 and the long screw 303 is reduced, which facilitates the rotation of the pressure roller 301 and further saves effort. The detachable nut 304 and the long screw 303 facilitate the disassembly and assembly of the pressure roller 301, thereby facilitating the replacement and maintenance of the pressure roller 301 in the future and improving its practicality.

[0026] Working Principle: When using this device, the handle 11 is gripped to push the device, moving the pressure roller 301 to the corner of the asphalt road for compaction. While pushing the device, the electric telescopic rod 2 is activated, causing the power roller 403 in the power assembly 4 to descend to a suitable position in contact with the ground. Then, the drive motor 405 is activated, driving the second pulley 406 to rotate. This, in conjunction with the transmission belt 407, drives the first pulley 404 and the rotating shaft 402 to rotate, thereby driving the power roller 403 to rotate. The rotation of the power roller 403 after contact with the ground effectively propels the device. The problem of the excessive weight of the pressure roller 301 making it difficult to push has been solved. By using a heavier pressure roller 301, the compaction effect is improved, and it is more labor-saving and convenient to use. The bearing 302 placed between the pressure roller 301 and the long screw 303 reduces the friction between the pressure roller 301 and the long screw 303, making it easier for the pressure roller 301 to rotate and further saving labor. The detachable nut 304 and the long screw 303 facilitate the disassembly and assembly of the pressure roller 301, thereby facilitating the replacement and maintenance of the pressure roller 301 in the future and improving its practicality.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
