[0027] refer to Figure 1 to Figure 5 It should be understood that Figure 5 The connections between the components should be like Figure 1 As compact as in the example, this is just an example. Figure 5Some of the components in the middle are displayed separately for easy understanding. An embodiment of the present application provides an asphalt pavement grouting device, which may include a base frame 1, a liquid storage tank 2, a liquid outlet pipe 3 and a baffle 4, wherein the base frame 1 has a top side and a bottom side arranged opposite to each other in a first direction, and the first direction is the same as the thickness direction of the base frame 1; the liquid storage tank 2 is arranged on the top side of the base frame 1 and a through hole 21 is arranged on the side away from the base frame 1, and a liquid outlet hole 22 is arranged on the side of the liquid storage tank 2 in the second direction, and the second direction is perpendicular to the first direction; one end of the liquid outlet pipe 3 is penetrated by the liquid outlet hole 22 and is fixed to the liquid storage tank 2; the baffle 4 is penetrated by the through hole 21 and is rotatably connected to the liquid storage tank 2, and the baffle 4 has the freedom to rotate around the second direction; wherein the baffle 4 rotates around the second direction in response to the driving force to close or completely open the liquid outlet pipe 3.

[0028] An asphalt pavement crack filling device proposed in an embodiment of the present application adds asphalt into a liquid storage tank 2. When in use, the base frame 1 is moved to the road surface so that the liquid outlet pipe 3 is located directly above the crack. The baffle 4 is manually rotated about the second direction so that the baffle 4 gradually and completely opens the liquid outlet pipe 3, and the asphalt gradually flows into the crack. In the process of the baffle 4 rotating about the second direction to completely open the liquid outlet pipe 3, the area of ​​the baffle 4 blocking the liquid outlet pipe 3 gradually becomes smaller, and at this time the asphalt flow rate gradually increases; in the process of the baffle 4 rotating about the second direction to close the liquid outlet pipe 3, the area of ​​the baffle 4 blocking the liquid outlet pipe 3 gradually becomes larger, and at this time the asphalt flow rate gradually decreases, that is, the area of ​​the baffle 4 blocking the liquid outlet pipe 3 can be controlled by rotating the angle of the baffle 4, and the asphalt flow rate can be further controlled to facilitate the pouring of cracks of different sizes.

[0029] Specifically, Figure 1 As shown, the first direction is the X direction, the second direction is the Y direction, the base frame 1 can be a frame body formed by welding multiple rod-shaped steel pipes, and the whole is a giant rectangle. The first direction is the thickness direction of the base frame 1, and the second direction is the width direction of the base frame 1.

[0030] Furthermore, the connection area between the baffle 4 and the liquid storage tank 2 is located inside the liquid storage tank 2, and the closer the connection area between the baffle 4 and the liquid storage tank 2 is to the liquid outlet pipe 3, the greater the angle that the baffle 4 needs to rotate to change from a closed liquid outlet pipe 3 state to a fully open liquid outlet pipe 3 state, and similarly, the accuracy of asphalt flow control will also be improved.

[0031] refer to Figure 1 and Figure 2In an exemplary embodiment, the asphalt pavement grouting equipment may further include a plurality of running wheels 51 and two support rods 52, wherein the plurality of running wheels 51 are arranged on the periphery of the base frame 1; the two support rods 52 are relatively arranged on the top side of the base frame 1 in the second direction Y, and the support rods 52 and the liquid storage tank 2 are arranged side by side in a third direction, and the third direction is respectively perpendicular to the first direction X and the second direction Y; and a handle 53 is fixed to one end of the two support rods 52 away from the base frame 1.

[0032] Specifically, Figure 1 As shown, the third direction is the Z direction, that is, the length direction of the base frame 1; the user holds the handle 53 and pushes it, and the base frame 1 can be driven to move through the walking wheel 51 through the support rod 52, which makes it easy to move the asphalt pavement grouting equipment. At the same time, for longer cracks, pouring can be carried out while pushing the handle 53 to move the liquid outlet pipe 3 above the crack, making pouring more convenient.

[0033] refer to Figure 1 to Figure 3 In an exemplary embodiment, the asphalt pavement grouting equipment may further include a first rotating shaft 6, a hand wheel 7 and a transmission assembly 8, wherein the first rotating shaft 6 is rotatably connected to a support rod 52 near the liquid outlet 22, the axial direction of the first rotating shaft 6 is the same as the second direction Y and has the freedom to rotate around its own axial direction; the hand wheel 7 is sleeved on the outer periphery of the first rotating shaft 6; the transmission assembly 8 connects the hand wheel 7 and one end of the baffle 4 located outside the liquid storage tank 2, and the transmission assembly 8 provides driving force for the baffle 4.

[0034] Specifically, the handwheel 7 is sleeved on the outer periphery of the first rotating shaft 6. Turning the handwheel 7 can drive the first rotating shaft 6 to rotate around its own axis. The first rotating shaft 6 drives the baffle 4 to rotate around the second direction Y through the transmission assembly 8 to close or completely open the liquid outlet pipe 3, or to adjust the asphalt flow rate; the handwheel 7 and the first rotating shaft 6 are both located at the support rod 52, so that in the process of pushing the base frame 1 to move, the asphalt flow rate can be adjusted by turning the handwheel 7, and the operation can be completed by one person, making it more convenient to cast longer cracks.

[0035] refer to Figure 2 and Figure 3In an exemplary embodiment, the transmission assembly 8 may include a second rotating shaft 81, a transmission part 82, a first connecting rod 83 and a second connecting rod 84, wherein the second rotating shaft 81 is rotatably connected to the support rod 52 near the liquid outlet 22, the axial direction of the second rotating shaft 81 is the same as the second direction Y and has the freedom to rotate around its own axial direction; the transmission part 82 connects the first rotating shaft 6 and the second rotating shaft 81, wherein the first rotating shaft 6 provides a rotational driving force for the second rotating shaft 81 through the transmission part 82; the first connecting rod 83 is arranged on the top side of the base frame 1 and the end away from the base frame 1 is fixed to the second rotating shaft 81; the two ends of the second connecting rod 84 are respectively rotatably connected to the end of the first connecting rod 83 near the base frame 1 and the baffle 4, and the second connecting rod 84 has the freedom to rotate around the second direction Y.

[0036] Specifically, when the hand wheel 7 is turned to drive the first rotating shaft 6 to rotate, the first rotating shaft 6 drives the second rotating shaft 81 to rotate around the axial direction of the second rotating shaft 81 through the transmission part 82, and the second rotating shaft 81 drives the first connecting rod 83 to swing around the second rotating shaft 81, and the two ends of the second connecting rod 84 are respectively rotated to connect the end of the first connecting rod 83 close to the base frame 1 and the baffle 4, so that when the first connecting rod 83 swings around the second rotating shaft 81, it drives the second connecting rod 84 to rotate around the second direction Y. During the rotation of the second connecting rod 84, it drives the baffle 4 to rotate around the connection area between the baffle 4 and the liquid storage tank 2 to adjust the flow rate.

[0037] refer to Figure 2 and Figure 3 In an exemplary embodiment, the second rotating shaft 81 passes through the corresponding support rod 52; the first rotating shaft 6 and the first connecting rod 83 are located on opposite sides of the corresponding support rod 52 in the second direction Y, wherein the first connecting rod 83 is located between the two support rods 52.

[0038] Specifically, the first connecting rod 83 is located between the two support rods 52, and the first rotating shaft 6 and the hand wheel 7 are located on the outer side of the corresponding support rod 52 away from the other support rod 52. In this way, the user can push the asphalt pavement grouting equipment with one hand and turn the hand wheel 7 with the other hand to adjust the asphalt flow rate, which is more convenient to use.

[0039] Furthermore, the first rotating shaft 6 and the first connecting rod 83 are located on opposite sides of the corresponding support rod 52 in the second direction Y, so that the user will not touch the first connecting rod 83 or the second connecting rod 84 when turning the hand wheel 7, and the operation is more convenient.

[0040] refer to Figure 3In an exemplary embodiment, the transmission part 82 may include a driving gear 821 and a driven gear 822, wherein the driving gear 821 is sleeved on the outer periphery of the first rotating shaft 6 and is located between the hand wheel 7 and the support rod 52; the driven gear 822 is sleeved on the outer periphery of the second rotating shaft 81 and meshes with the driving gear 821; the transmission ratio of the driving gear 821 to the driven gear 822 is a, and 1<a≤12.

[0041] Specifically, when the first rotating shaft 6 rotates, it drives the driving gear 821 to rotate, and the driving gear 821 is meshed with the driven gear 822. When the driving gear 821 rotates, it drives the driven gear 822 and the second rotating shaft 81 to rotate around the axial direction of the second rotating shaft 81, thereby realizing transmission between the first rotating shaft 6 and the second rotating shaft 81.

[0042] Furthermore, the transmission ratio of the driving gear 821 to the driven gear 822 is a, and 1<a≤12. If the angle that the baffle 4 needs to rotate from the state of closing the liquid outlet pipe 3 to the state of fully opening the liquid outlet pipe 3 remains unchanged, then the larger the value of a is, the larger the angle that the driving gear 821 needs to rotate is, so that it can finally drive the baffle 4 to rotate the corresponding angle. Similarly, the higher the control accuracy of the angle of rotation of the baffle 4, in other words, the larger the value of a is, the larger the angle that the driving gear 821 needs to rotate is, and the higher the accuracy of adjusting the asphalt flow rate is, but correspondingly, the rate of adjusting the asphalt flow rate is slower.

[0043] In the embodiment of the present application, a=6, at which time the accuracy of adjusting the asphalt flow rate can meet the demand, and the working efficiency is relatively high.

[0044] refer to Figure 1 and Figure 4 In an exemplary embodiment, the through hole 21 is a strip hole, and the length direction of the strip hole is the same as the third direction Z; wherein, in the third direction Z, the maximum movable length of the baffle 4 on the side of the liquid storage tank 2 away from the base frame 1 is d1, the length of the strip hole is d2, and d2 ≥ d1; when the end of the strip hole away from the support rod 52 collides with the baffle 4, the baffle 4 closes the liquid outlet pipe 3; when the end of the strip hole close to the support rod 52 collides with the baffle 4, the baffle 4 completely opens the liquid outlet pipe 3.

[0045] Specifically, the rotation range of the baffle 4 from closing the liquid outlet pipe 3 to fully opening the liquid outlet pipe 3 is the maximum movable range of the baffle 4, and corresponds to the maximum movable length of the baffle 4 on the side of the liquid storage tank 2 away from the base frame 1; when d2>d1, the through hole 21 will not affect the rotation of the baffle 4 around the second direction Y, that is, it will not affect the process of the baffle 4 fully opening or closing the liquid outlet pipe 3, thereby ensuring the normal operation of the asphalt flow regulation operation.

[0046] Furthermore, if d2=d1, when the baffle 4 closes the liquid outlet pipe 3, the baffle 4 contacts the end of the through hole 21 away from the support rod 52; when the baffle 4 completely opens the liquid outlet pipe 3, the baffle 4 contacts the end of the through hole 21 close to the support rod 52; this makes it easy to observe when the asphalt flow reaches a maximum and when it reaches a minimum, which is more convenient to use.

[0047] refer to Figure 4 and Figure 5 In an exemplary embodiment, a liquid inlet 23 is provided on the side of the liquid storage tank 2 facing away from the base frame 1, and a flange structure facing the outside of the liquid storage tank 2 is provided at the liquid inlet 23; the asphalt pavement grouting equipment may also include two support parts 91 and a cover 92, wherein the two support parts 91 are relatively arranged on the same side of the flange structure; the cover 92 is arranged on the side of the liquid storage tank 2 facing away from the base frame 1 and has a U-shaped flange structure facing the liquid storage tank 2 on the outer periphery, the flange structure on the cover 92 is located on the outer periphery of the flange structure on the liquid storage tank 2 and is rotatably connected to the two support parts 91; wherein the two support parts 91 are both located at the notch of the flange structure on the cover 92.

[0048] Specifically, the U-shaped flange structure on the cover 92 wraps around and fits the flange structure on the liquid storage tank 2, which has a better sealing effect. The cover 92 can be opened or closed by pulling the cover 92 to rotate it around the two support parts 91 in opposite directions.

[0049] The relative direction of the two supporting portions 91 may be the third direction Z or the second direction Y. In short, the relative direction of the two supporting portions 91 may be perpendicular to the first direction X.

[0050] It should be understood that the two support portions 91 are located on the side of the flange structure on the liquid storage tank 2 that is not wrapped by the U-shaped flange structure on the cover 92 .

[0051] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
