Description

Technical Field

[0001] The present application relates to the technical field of road construction equipment, and in particular to an asphalt pavement joint device. Background Art

[0002] During asphalt pavement construction, if the interval between asphalt paving on both sides is too long, joints are likely to form at the junction of the two paving layers. The presence of joints not only affects the appearance of the pavement, but also has a significant impact on the quality of the asphalt pavement, significantly shortening the service life of the asphalt pavement. The asphalt pavement joint repair device is one of the devices used for asphalt pavement joint repair, which can complete the repair of asphalt pavement joints.

[0003] The asphalt pavement joint device is generally composed of a frame assembly, a cleaning assembly and a joint repair assembly. The movement of the frame assembly drives the joint repair assembly to move above the asphalt pavement joint, and during the movement, the heated asphalt is poured into the pavement joint, and then the pavement joint is repaired with a rolling process.

[0004] However, in existing joint cleaning devices, the sweeping wheels used to clean debris such as gravel from the road surface are typically cylindrical. During the joint cleaning process, gravel and other debris are often pushed from the outside of the joint to the inside, affecting the subsequent asphalt filling of the joint. Furthermore, the sweeping wheels rotate to clean the gravel as the joint cleaning device moves relative to the road surface. This slows the speed of the joint cleaning device relative to the road surface during joint cleaning, further reducing the effectiveness of cleaning debris such as gravel, and ultimately significantly degrading the quality of the asphalt pavement. Utility Model Content

[0005] The present application aims to solve at least one of the technical problems existing in the related art. To this end, the present application proposes an asphalt pavement joint device. By optimizing and adjusting the structure of a cleaning component, the device has outer peripheral walls of different diameters along the axial direction. When the cleaning component rotates relative to the road surface, the outer peripheral wall with a larger diameter protrudes deeper into the joint, thereby preventing debris such as gravel from entering the joint. This increases the cleaning effect of the cleaning component on gravel and other debris in the road surface joint, better filling the road surface joint with asphalt, and thus significantly improving the quality of the asphalt pavement.

[0006] The present application provides an asphalt pavement joint device, which includes:

[0007] A frame assembly is provided with a load-bearing plate with pulleys;

[0018] The other end of the carrying plate is provided with a hand support extending in the vertical direction;

[0019] One end of the driving assembly is transmission-connected to the cleaning assembly, and the other end of the driving assembly is mounted on the upper end of the hand bracket.

[0047] like Figures 1 to 7 As shown, in the embodiment of the present application, an asphalt pavement joint device is introduced. The asphalt pavement joint device mainly includes: a frame assembly 100, a cleaning assembly 200, a joint repair assembly 300 and a driving assembly 400.

[0048] Specifically, the frame assembly 100 is provided with a bearing plate 110 with pulleys for carrying a container 310 containing asphalt and fixing various functional components. The cleaning assembly 200 is mounted on one end of the bearing plate 110 and mainly includes a road cleaning wheel for cleaning road debris.

[0049] The joint repair assembly 300 primarily comprises a container 310 for holding raw asphalt and a feeding pipe 320 for dispensing asphalt onto the cleaned road surface. Container 310 is mounted above the carrier plate 110. The feeding pipe 320 extends through the carrier plate 110, with its upper end connected to container 310 and its lower end positioned behind the road-cleaning wheels.

[0050] Specifically, cleaning assembly 200 is configured as a cylindrical structure with its central axis parallel to the horizontal line, and its diameter in the middle is larger than its diameter at its ends. Specifically, cleaning assembly 200 is configured as a cylinder that rotates about the horizontal line, with a larger diameter in the middle and smaller diameters at its ends. Thus, when cleaning assembly 200 is positioned at the front end of carrier plate 110, it can be used to remove debris and debris from the road surface and the road joints before the joint device is moved.

[0051] Furthermore, if Figures 1 to 4 As shown, a hand bracket 111 is provided on the carrying plate 110. A handle is provided on the top of the hand bracket 111 to facilitate the operator to control and push the seaming device to move.

[0052] A support frame 120 is provided at the front end of the carrier plate 110. A rotating shaft is provided on the support frame 120 for mounting the cleaning assembly 200.

[0053] Furthermore, the cleaning assembly 200 includes a joint cleaning structure 210 and a road sweeping wheel 240. The diameter of the joint cleaning structure 210 is larger than the diameter of the road sweeping wheel 240. Moreover, the joint cleaning structure 210 is sandwiched between the two road sweeping wheels 240.

[0054] Furthermore, the joint cleaning structure 210 and the road sweeping wheel 240 are arranged with their central axes aligned, thereby enabling them to rotate in unison. Specifically, the joint cleaning structure 210 and the road sweeping wheel 240 are sleeved on the same rotating shaft, and one end of the rotating shaft can drive the joint cleaning structure 210 and the road sweeping wheel 240 to rotate synchronously.

[0055] Preferably, the two road sweeping wheels 240 are connected to either side of the carrier plate 110 via the support frame 120. A first insertion slot 241 is provided on the end surface of each road sweeping wheel 240. When the joint cleaning structure 210 is sandwiched between the two road sweeping wheels 240, it can be connected to the joint cleaning wheels 240 via the first insertion slot 241. This allows for quick assembly, disassembly, and replacement of the joint cleaning structure 210 through the first insertion slot 241, facilitating maintenance of the cleaning assembly 200 and replacement of easily consumable parts.

[0056] In this embodiment, by optimizing and adjusting the structure of the cleaning assembly 200 so that it has outer peripheral walls of different diameters along the axial direction, when the cleaning assembly 200 rotates relative to the road surface, the outer peripheral wall with a larger diameter will protrude deeper into the joint, thereby preventing debris such as gravel from entering the joint. This increases the cleaning effect of the cleaning assembly 200 on debris such as gravel at the road surface joints, and can better fill the asphalt in the road surface joints, thereby greatly improving the quality of the asphalt pavement.

[0057] Based on the above embodiment, another embodiment of the present application provides an asphalt pavement joint device.

[0058] like Figure 5 and Figure 6 As shown, the joint cleaning structure 210 includes a connecting post 230 and a joint cleaning wheel 220 sleeved on the connecting post 230. Since the diameter of the joint cleaning wheel 220 is larger than the diameter of the road cleaning wheel 240, the joint cleaning wheel 220 wears faster than the road cleaning wheel 240 during actual use, and the joint cleaning structure 210 needs to be replaced frequently. Therefore, setting it up as two parts can reduce replacement and maintenance costs.

[0059] Specifically, the end face of the road sweeping wheel 240 is provided with a first plug-in slot 241, and the connecting post 230 is detachably connected to the first plug-in slot 241. In this way, after the connecting post 230 is pulled out from the first plug-in slot 241, the gap sweeping wheel can be easily replaced.

[0060] On the basis of the above embodiment, in another embodiment of the present application, a structure is provided that can more conveniently install and disassemble the seam cleaning structure 210.

[0061] like Figure 6 As shown, a second plug-in slot 231 is provided on the end surface of the connecting post 230 .

[0062] The joint cleaning structure 210 is further provided with an inserting plate 250 . The inserting plate 250 is telescopically arranged in the second inserting slot 231 for connecting with the road sweeping wheel 240 .

[0063] Furthermore, an elastic member 260 is installed in the second insertion slot 231. One end of the elastic member 260 abuts against the insert plate 250, while the other end abuts against the second insertion slot 231. When installing or removing the joint cleaning structure 210, the insert plate 250 is pressed into the second connection slot, allowing the connecting post 230 to be easily inserted into or removed from the first insertion slot 241. This compresses the elastic member 260. After installation or removal, the elastic member 260 returns to its original length, pushing the insert plate 250 out of the second insertion slot 231.

[0064] On the basis of the above embodiment, in another embodiment of the present application, a seam cleaning structure 210 is provided that can be easily assembled and disassembled without the aid of tools.

[0065] like Figure 5 and Figure 6 As shown, the inserting plate 250 is provided with a paddle 251. The paddle 251 extends outward from the outer circumference of the inserting plate 250 along the radial direction of the inserting plate 250, so that in the process of using the seam device, even without tools, the movable inserting plate 250 can be easily controlled to maintain the seam cleaning structure 210.

[0066] On the basis of the above embodiment, in another embodiment of the present application, an asphalt pavement joint device capable of adjusting the rotation speed of a cleaning assembly 200 is provided.

[0067] The asphalt pavement joint device further includes a driving assembly 400 for driving the cleaning assembly 200 to rotate.

[0068] The other end of the carrying plate 110 is provided with a hand bracket 111 extending in a vertical direction. One end of the driving assembly 400 is transmission-connected to the cleaning assembly 200 , and the other end of the driving assembly 400 is mounted on the upper end of the hand bracket 111 .

[0069] Specifically, the drive assembly 400 includes a drive shaft 410, a drive pulley 420, a driven pulley 430, and a transmission belt 440. The drive shaft 410 is horizontally disposed at the upper end of the hand support 111. The drive pulley 420 is sleeved with the drive shaft 410. The driven pulley 430 is coaxially disposed with the road sweeping wheel 240. One end of the transmission belt 440 is sleeved with the drive pulley 420, and the other end of the transmission belt 440 is sleeved with the driven pulley 430.

[0070] Furthermore, to drive the road sweeping wheels 240 from both ends of the cleaning assembly 200, thereby adapting to various transmission structures, two symmetrical transmission routes can be provided in the drive assembly 400. Specifically, a drive pulley 420 is provided at each end of the drive shaft 410. Each drive pulley 420 is connected to a road sweeping wheel 240 via a transmission belt 440.

[0071] Based on the above embodiment, another embodiment of the present application provides an asphalt pavement joint device, wherein a crank 411 is provided at the end of the driving shaft 410 for manually controlling the rotation of the cleaning assembly 200 .

[0072] Furthermore, to better coordinate the joint repair assembly 300 and the cleaning assembly 200 in treating road joints, the joint repair assembly 300 is provided with a filling pipe 320. The filling pipe 320 vertically penetrates the support plate 110 and is connected to the container 310. The discharge port of the filling pipe 320 is located below the support plate 110.

[0073] Preferably, the filling pipe 320 and the joint cleaning structure 210 are aligned along the symmetry line of the bearing plate 110, so that asphalt can be accurately filled into the road joint cleaned by the cleaning structure.

[0074] In another embodiment of the present application, based on the above embodiment, a joint repair assembly 300 includes a container 310, a stirring structure, a feed pipe, and a filling pipe 320. Specifically, the stirring structure is provided on the container 310 to stir the asphalt raw material contained within the container 310 to prevent the asphalt raw material from coagulating within the container 310. Furthermore, a heating structure may be provided on the container 310 to heat the asphalt within the container 310.

[0075] A feed pipe is installed at the bottom of container 310. This pipe is equipped with a control switch and is located above the support plate 110. A filling pipe 320 is connected to the feed pipe. When the control switch is turned on, the asphalt feedstock in container 310 flows through the feed pipe into the filling pipe 320, which then delivers the asphalt feedstock to the bottom of the support plate 110.

[0076] On the basis of the above embodiment, the support frame 120 is configured to be L-shaped, which can ensure the stability of the road sweeping wheel 240 during rotation, thereby driving the cleaning assembly 200 to smoothly clean gravel and debris on the road surface.

[0077] In addition, in this application, the working principle of the asphalt pavement joint device is as follows:

[0078] Turn on the control switch on the feed pipe, and the asphalt raw material in the container 310 will be transported to the filling pipe 320 through the feed pipe. At the same time, the operator pushes the joint device to move along the joint, and the asphalt raw material flowing out of the filling pipe 320 fills the joint of the asphalt pavement as it moves.

[0079] Furthermore, during this process, the operator can control and adjust the rotation speed of the drive shaft 410 via the crank 411, thereby indirectly adjusting the rotation speed of the cleaning assembly 200 via the drive pulley 420, the transmission belt 440, and the driven pulley 430. This allows the asphalt pavement joint cleaning device to have the function of adjusting the rotation speed of the cleaning assembly 200, making it more adaptable to various working conditions.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.

[0081] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
