Description

Technical Field

[0001] This utility model relates to the technical field of grouting auxiliary devices, and in particular to a road grouting and smoothing device. Background Technology

[0002] In the construction and maintenance of roads, the repair of road surface cracks is a routine operation. The common method for repairing road surface cracks is grouting, which involves cutting the cracked area to a certain extent, filling it with prepared grout, and then vibrating, smoothing, and drying it to restore the original stability and strength of the road surface. However, currently, smoothing after grouting is usually done manually. But the strength and effect of manual smoothing are limited, making it easy for air bubbles to exist in the repaired area, and the smoothness of manual smoothing is limited. In view of this, this application proposes a road surface grouting and smoothing device. Utility Model Content

[0003] To address the above situation and overcome the shortcomings of existing technologies, this utility model provides a road grouting and smoothing device. The technical solution it provides includes an annular baffle. The annular baffle has an end cap connected to its upper flange, and a push-pull rod is detachably connected to the upper end of the end cap. Two connecting rods symmetrically arranged about their axes are fixedly connected to the inner wall of the annular baffle. Support frames are fixedly connected to the opposite ends of the two connecting rods. A drive shaft is rotatably connected to the opposite ends of the two support frames. A vibration block is eccentrically fixedly connected to the drive shaft. A power component for driving the drive shaft is fixedly connected to the support frames. Vertically arranged mounting sleeves are fixedly connected to the lower ends of each support frame. Support rods are slidably connected to each mounting sleeve. Buffer springs are coaxially arranged inside each mounting sleeve. The upper and lower ends of each buffer spring are fixedly connected to the inner bottom surface of the mounting sleeve and the upper end surface of the support rod, respectively. A smoothing disc is fixedly connected to the lower ends of both support rods.

[0004] Preferably, each of the mounting sleeves has two guide grooves symmetrically arranged about its axis on its outer edge, and each of the support rods has two guide blocks symmetrically arranged about its axis fixedly connected to its outer edge. The guide grooves and guide blocks correspond one-to-one and are vertically slidably connected.

[0005] Preferably, a handle is fixedly connected to the upper end of the push-pull rod.

[0006] Preferably, the power assembly includes a power motor that is fixedly connected to the support frame and is used to drive the drive shaft.

[0007] The beneficial effects of this utility model are: When using this application, specifically when smoothing is required after grouting, the smoothing disc of this application comes into contact with the grouting material. The power unit is activated, and the push-pull rod is pulled to move this application. The power motor of the power unit starts, which drives the transmission shaft to rotate. The rotation of the transmission shaft causes the vibrating block, which is eccentrically fixed to it, to rotate as well. Due to the eccentric setting, the rotation of the vibrating block will drive the annular baffle and the entire application to vibrate through the transmission shaft. During the movement of this application by the push-pull rod, a certain amount of vibration will also be generated, which can vibrate and smooth the grouting material below, avoiding the presence of air bubbles in the grouting material. After vibrating and smoothing for a certain period of time, the power motor is turned off, but the application is still moved by the push rod at its limit, thereby ensuring the smoothness of the smoothing. This application has a simple structure, is easy to use, and is highly practical. Attached Figure Description

[0014] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.

[0015] In Embodiment 1, the technical solution is as follows: When using this application, specifically when smoothing is required after grouting, the smoothing disc 11 of this application comes into contact with the grouting material. The power assembly is activated, and the push-pull rod 3 is pulled to move this application. The power motor 15 of the power assembly starts, driving the transmission shaft 6 to rotate. The rotation of the transmission shaft 6 causes the vibrating block 7, which is eccentrically fixed to it, to rotate as well. Due to the eccentric setting, the rotation of the vibrating block 7 will cause the annular baffle 1 and the entire application to vibrate through the transmission shaft 6. During the movement of this application via the push-pull rod 3, a certain amount of vibration will also be generated, which can vibrate and smooth the grouting material below, preventing air bubbles from forming in the grouting material. After vibrating and smoothing for a certain period, the power motor 15 is turned off, but the application is still moved by the push rod to ensure the smoothness of the smoothing. This application has a simple structure, is easy to use, and is highly practical. Furthermore, this application is equipped with a buffer spring 10 through components such as the mounting sleeve 8, which can ensure the vibration force and stability of the smoothing disc 11, ensuring the effectiveness of this application.

[0016] In Example 2, based on Example 1, specifically, in order to facilitate the movement of this application during use, a push-pull rod 3 and a handle 14 are provided above the end cap 2, so that the smoothing plate 11 and the entire application can be moved on the grouting material by the push-pull rod 3, and smoothing operations can be performed by the smoothing plate 11.

[0017] Specifically, the support frame 5 of this application is set inside the annular cover 1 via the connecting rod 4, and the support frame 5 is equipped with a power motor 15 that can drive the transmission shaft 6 to rotate. When the application is moved by the push-pull rod 3 to perform the smoothing operation, the drive motor is first started to drive the drive shaft and the vibration block 7 to rotate together. Since the vibration block 7 is eccentrically set, it will drive the application, including the smoothing disc 11, to vibrate during its rotation. Thus, the smoothing disc 11 can smooth while vibrating, and the vibration can effectively remove air bubbles in the grouting material. Furthermore, after vibrating for a certain period of time, the power motor 15 is turned off, the vibration stops, and the application is moved only by the push-pull rod 3 to ensure the smoothness of the smoothing.

[0018] Furthermore, in order to avoid excessive vibration caused by the vibrating block 7 affecting the working effect of the smoothing disc 11 during use, a buffer spring 10 is provided. During the vibration process caused by the vibrating block 7, under the action of the support spring, the support rod 9 can move along the axial direction of the mounting sleeve 8 under the guidance of the guide block 13 and the guide groove 12, thereby deforming the buffer spring 10. The deformation of the buffer spring 10 can effectively control the vibration effect, thereby ensuring the vibration force of the smoothing disc 11 and ensuring the practical effect of the smoothing disc 11.

[0019] In Example 3, based on Example 2, both the end cap 2 and the push-pull rod 3 of this application are connected by flanges, that is, the flange is connected with bolts, which facilitates disassembly and maintenance.
