Technical Field
[0001] This utility model relates to the field of asphalt crack sealing technology, specifically an asphalt crack sealing device for municipal roads. Background Technology
[0002] Asphalt crack sealing technology is an effective preventive protection method. It is a preventive maintenance construction method for pavement base courses and cross sections that are in good condition, with only longitudinal and transverse cracks on the surface, accompanied by many fine expanding cracks, and with a relatively low crack density.
[0003] Current asphalt crack sealing equipment still requires manual operation during asphalt crack sealing. However, prolonged manual operation puts enormous pressure and strain on the worker's arms, easily leading to fatigue and soreness, which seriously affects the worker's work efficiency and health. Utility Model Content
[0004] The purpose of this invention is to provide an asphalt crack sealing device for municipal roads, which aims to solve the problem that in the existing technology, workers' hands are used for operation, which can easily cause arm fatigue and soreness over a long period of time, affecting workers' work efficiency and physical health.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: the asphalt crack sealing device for municipal roads includes a mobile trolley assembly, an asphalt crack sealing device placed on the mobile trolley assembly, and an auxiliary support assembly; The asphalt crack sealing device includes an asphalt crack sealing body, a connecting pipe connected to the asphalt crack sealing body, and a nozzle head assembly that is detachably connected to the end of the connecting pipe away from the asphalt crack sealing body. The auxiliary support assembly supports the connecting pipe and the nozzle head assembly; The auxiliary support assembly includes a support moving assembly and several sets of fixing assemblies disposed on the surface of the support moving assembly. The fixing assemblies can snap the connecting pipe and the nozzle head assembly onto the surface of the support moving assembly, and the side of the nozzle head assembly away from the connecting pipe faces the road surface. The support moving component can drive the connecting pipe and nozzle head assembly fixed on the support moving component to move in order to fill the gaps in the road surface with asphalt.
[0006] Preferably, the supporting moving assembly includes a base plate, a support plate hinged to the base plate, a top plate hinged to the base plate, and a plurality of casters disposed at the bottom of the base plate; The bottom of the support plate is fixed with several protruding strips that extend in the front-back direction and are spaced apart from each other, so that when the top plate is flipped up, it can rest against the protruding strips to support the support plate. The fixing component is mounted on the surface of the support plate.
[0007] Preferably, the support plate has a limiting guide groove extending in the front-to-back direction and opening to the right, and the fixing component is disposed in the limiting guide groove so that the fixing component can move along the extending direction of the limiting guide groove to clamp the connecting pipe.
[0008] Preferably, the fixing assembly includes a bidirectional lead screw extending in the left-right direction, two movable blocks threaded onto the bidirectional lead screw, and an arc-shaped clamp fixed onto the movable blocks. One end of the bidirectional lead screw passes through the support plate and is fixed with a handle. Two moving blocks slide within the limiting guide groove, so that when the bidirectional lead screw rotates, it can drive the two moving blocks to move in opposite or opposite directions along the extension direction of the limiting guide groove, so that the two arc-shaped clamps are clamped on the outside of the connecting pipe.
[0009] Preferably, the nozzle head assembly and the connecting pipe are detachably connected via a connecting assembly.
[0010] Preferably, the connecting assembly includes a first flange fixed to the nozzle head assembly and a second flange fixed to the end of the connecting pipe away from the asphalt sealant body; The first flange has a first circular hole that is open to both sides, and the second flange has a second circular hole that is open to both sides. The first circular hole and the second circular hole correspond to each other, and the first flange and the second flange can be connected by fasteners.
[0011] Preferably, the fastener includes a stud that passes through the first circular hole and the second circular hole and a nut that is threaded to fit the ends of the stud; The stud has a first and a second round hole at both ends that are threaded to fit the nut.
[0012] Preferably, a rubber ring is provided between the first flange and the second flange.
[0013] The beneficial effects are: 1. The worker first securely installs the connecting pipe onto the support plate, then gently pushes the auxiliary support assembly. This action allows the auxiliary support assembly to slide smoothly along the direction of the gap, thereby driving the nozzle head assembly to move synchronously and accurately align with the filling position. This design cleverly eliminates the need for the worker to hold the nozzle head assembly, effectively reducing arm fatigue and soreness caused by prolonged holding, significantly improving worker comfort and reducing labor intensity.
[0014] 2. Through cleverly designed protruding strips, the top plate can be flipped to different angles as needed, thereby flexibly adjusting the support angle of the support plate. This design allows the support plate to precisely match the angle according to the inclination of the connecting pipe, ensuring that the nozzle head assembly can adaptively adjust its angle according to the specific direction of the gap, achieving the best grouting effect.
[0015] 3. The nozzle head assembly includes nozzle connectors of various sizes, allowing workers to quickly change the appropriate connector based on the actual size of the crack. This flexibility not only improves the adaptability and efficiency of asphalt crack sealing operations but also ensures construction quality and avoids repetitive work caused by mismatched nozzle sizes.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0019] An asphalt crack sealing device for municipal roads is mainly used by workers to manually push the auxiliary support component for movement, eliminating the need to hold the nozzle head component 203 by hand, thus avoiding arm pain caused by prolonged hand holding. In addition, the nozzle head component 203 can be replaced according to the size of the crack to improve applicability.
[0020] In this embodiment, the asphalt crack sealing device includes a mobile trolley assembly 1, an asphalt crack sealing device 2 placed on the mobile trolley assembly 1, and an auxiliary support assembly. The mobile trolley assembly 1 can carry the asphalt crack sealing device 2 to move, so that the asphalt crack sealing device 2 can easily transport asphalt, while the auxiliary support assembly can support the asphalt crack sealing device 2, which greatly reduces the labor intensity of the workers.
[0021] like Figure 1 and Figure 2 As shown, the mobile trolley assembly 1 can carry the asphalt crack sealing device 2 to move, so that the asphalt crack sealing device 2 can easily transport asphalt.
[0022] Specifically, the asphalt crack sealing device 2 includes an asphalt crack sealing body 201, a connecting pipe 202 connected to the asphalt crack sealing body 201, and a nozzle head assembly 203 detachably connected to one end of the connecting pipe 202 away from the asphalt crack sealing body 201. In this embodiment, the structure and principle of the asphalt crack sealing device 2 are existing technologies and will not be described in detail here.
[0023] The auxiliary support assembly supports the connecting pipe 202 and the nozzle head assembly 203; The mobile trolley assembly 1 includes a mobile plate 101, several sets of rollers 102 fixed in a rectangular array at the bottom of the mobile plate 101, and pushers 103 fixed on the mobile plate 101. The asphalt grouting body 201 is installed on the mobile plate 101, so that workers can push the mobile plate 101 to move by pushing the pushers 103, thereby realizing the movement of the asphalt grouting body 201.
[0024] like Figure 1 , Figure 2 and Figure 5 As shown, the nozzle head assembly 203 can be removed from the connecting pipe 202, allowing the nozzle head assembly 203 to be replaced according to the size of the gap, thereby improving applicability.
[0025] Specifically, the nozzle head assembly 203 is available in different sizes, and the nozzle head assembly 203 and the connecting pipe 202 are detachably connected via the connecting component 7.
[0026] The connecting assembly 7 includes a first flange 701 fixed to the nozzle head assembly 203 and a second flange 702 fixed to the end of the connecting pipe 202 away from the asphalt grouting body 201. In this embodiment, the structure and principle of the first flange 701 and the second flange 702 are existing technologies and will not be described in detail here. The first flange 701 has a first circular hole that is open to both sides, and the second flange 702 has a second circular hole that is open to both sides. The first circular hole and the second circular hole correspond to each other, and the first flange 701 and the second flange 702 can be connected by fasteners.
[0027] The fasteners include studs 8 that pass through the first and second round holes and nuts 9 that are threaded to fit the ends of the studs 8. When the first and second round holes correspond to each other, the studs 8 are passed through the first and second round holes, and the ends of the studs 8 protrude from the first and second round holes and are threaded to fit the nuts 9, so as to achieve a fixed connection between the first flange 701 and the second flange 702. A rubber ring is provided between the first flange 701 and the second flange 702. The rubber ring can improve the sealing performance of the connection between the first flange 701 and the second flange 702.
[0028] like Figures 1-4 As shown, the connecting pipe 202 is installed on the auxiliary support assembly. Then, the staff pushes the auxiliary support assembly, which enables the connecting pipe 202 and the nozzle head assembly 203 to move, making it more convenient and free for the staff to perform asphalt grouting.
[0029] Specifically, the auxiliary support assembly includes a support moving assembly 301 and several sets of fixing assemblies 302 disposed on the surface of the support moving assembly 301. The fixing assemblies 302 can snap the connecting pipe 202 and the nozzle head assembly 203 onto the surface of the support moving assembly 301, and the side of the nozzle head assembly 203 away from the connecting pipe 202 faces the road surface. After the nozzle head assembly 203 is installed, it can push the support moving assembly 301 to move, so that the movement of the support moving assembly 301 can drive the connecting pipe 202 and the nozzle head assembly 203 fixed on the support moving assembly 301 to move, so asphalt can be injected into the gaps on the road surface.
[0030] The supporting moving assembly 301 includes a base plate 3011, a support plate 3012 hinged to the base plate 3011, a top plate 3013 hinged to the base plate 3011, and several casters 3014 set at the bottom of the base plate 3011. The casters 3014 can drive the base plate 3011 and the top plate 3013 to move, so that the nozzle head assembly 203 can move along the extension direction of the gap without the need for the operator to hold it. Several protrusions 4 extending in the front-back direction and spaced apart on the left and right are fixed at the bottom of the support plate 3012. After the top plate 3013 is flipped up, it can abut against the protrusions 4 to support the support plate 3012. The fixing assembly 302 is installed on the surface of the support plate 3012.
[0031] The support plate 3012 is provided with a limiting guide groove 5 extending in the front-back direction and opening to the right. The fixing component 302 is provided in the limiting guide groove 5. The fixing component 302 can move along the extension direction of the limiting guide groove 5 to clamp the connecting pipe 202 and fix the connecting pipe 202 to prevent the connecting pipe 202 from swinging during use.
[0032] The fixing assembly 302 includes a bidirectional lead screw 3021 extending in the left-right direction, two movable blocks 3022 threadedly connected to the bidirectional lead screw 3021, and an arc-shaped clamping plate 3023 fixed to the movable blocks 3022. One end of the bidirectional lead screw 3021 extends through the support plate 3012 and is fixed with a handle 6. Manually rotating the handle 6 can drive the bidirectional lead screw 3021 to rotate. When the bidirectional lead screw 3021 rotates, it can drive the two movable blocks 3022 to move in opposite or opposite directions along the extension direction of the limiting guide groove 5. The two arc-shaped clamping plates 3023 are clamped on the outside of the connecting pipe 202 to fix the connecting pipe 202.
[0033] Working principle: Place the connecting pipe 202 on the support plate 3012, then manually turn the handle 6 to drive the bidirectional screw 3021 to rotate. When the bidirectional screw 3021 rotates, it drives the two moving blocks 3022 to move in opposite or opposite directions along the extension direction of the limiting guide groove 5. The two arc-shaped clamps 3023 clamp the outside of the connecting pipe 202. Then, the worker pushes the auxiliary support assembly, which can drive the connecting pipe 202 and the nozzle head assembly 203 to move, making it more convenient and free for the worker to perform asphalt grouting. When it is necessary to replace the nozzle connector, the nut 9 and stud 8 can be removed first to disassemble the first flange 701 and the second flange 702. During installation, when the first round hole and the second round hole correspond, the stud 8 is inserted into the first round hole and the second round hole. The two ends of the stud 8 protrude from the first round hole and the second round hole and are threaded to the nut 9 to achieve a relatively fixed connection between the first flange 701 and the second flange 702, which improves the applicability of this device.
