Description

Technical Field

[0001] This invention relates to the field of asphalt pavement repair, and more particularly to a deep filling device for repairing cracks in asphalt pavement. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by mixing asphalt materials into 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. However, asphalt pavement can also suffer various types of damage after prolonged use. Common cracks and potholes are examples of damage to the integrity of asphalt pavement.

[0003] Currently, the repair of cracks in asphalt pavements is carried out by using high-temperature asphalt spraying to fill the cracks. However, the cracks in asphalt pavements are affected by vehicle traffic and generate a lot of dust. Repair personnel can only clean the surface of the asphalt pavement locally. The dust inside the cracks will reduce the adhesion between the high-temperature asphalt and the cracks in the pavement. Affected by the dust, the repaired cracks are prone to breakage again.

[0004] As shown above, the technical challenge that the inventors need to solve is to efficiently fill the cracks between the high-temperature asphalt and the asphalt pavement. Summary of the Invention

[0005] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted in this invention is as follows:

[0007] A deep filling device for repairing cracks in asphalt pavement includes a fixing mechanism, a load-bearing rolling mechanism, a sweeping mechanism, a transmission and dust removal mechanism, and an asphalt filling mechanism. The fixing mechanism includes a flow aid for guiding high-temperature asphalt. The load-bearing rolling mechanism includes a stabilizing part and a pressure plate assembly. The pressure plate assembly includes a shaft, a load-bearing weight plate movably mounted on the shaft, and a limiting outer shaft mounted on the shaft. The sweeping mechanism includes a slide rail, a bracket mounted inside the slide rail, a main pile mounted in the bracket, and a sweeping head connected to the bottom end of the main pile. The transmission and dust removal mechanism is installed on both sides outside the fixing mechanism. The asphalt filling mechanism includes a smoothing part for rolling high-temperature asphalt, a portable shaft built into the cavity of the smoothing part, and a spring core rod connected to the portable shaft.

[0008] By adopting the above technical solution, when using the device, the operator needs to adjust the overall adaptability of the device to the cracks according to the gaps in the cracks on the asphalt pavement. Then, the operator needs to control the device and move it backward so that the sweeping head is located inside the crack and the two ground dust sweeping parts are located on both sides of the crack.

[0009] In a preferred embodiment, the present invention may be further configured such that the fixing mechanism includes a housing, a guide tube installed inside the housing, and slide bars connected to both sides of the exterior of the housing.

[0010] By adopting the above technical solution, a guide pipe is fixedly installed inside the outer shell. With the bottom end of the guide pipe located in the middle of the smoothing component, when the smoothing component moves along the ground, the high-temperature asphalt will be rolled into the inside of the crack due to the smoothing effect of the smoothing component.

[0011] In a preferred embodiment, the present invention may be further configured such that the stabilizing unit includes a load-bearing frame connected to the outer casing, a crossbar mounted on the load-bearing frame, a pressure plate movably connected to the load-bearing frame, a sand and gravel bag built into the inner side of the load-bearing frame, and a pressurizing assembly mounted at the bottom of the load-bearing frame.

[0012] By adopting the above technical solution, multiple sand and gravel bags are movably placed inside the load-bearing frame. The fine sand and gravel inside the sand and gravel bags are evenly spread on the crack along the surface of the load-bearing weight plate. At this time, the device can directly roll on the crack and quickly flatten the repair position on the overall flatness of the asphalt road surface.

[0013] In a preferred embodiment, the invention may be further configured such that the pressurizing assembly includes a sleeve inserted into the shaft, a pressurizing element mounted outside the sleeve, and a rod movably connected to the inner cavity of the sleeve.

[0014] By adopting the above technical solution, using a sleeve and fixing a pressure booster on the annular protrusion on the outer side of the sleeve, when the weight of the entire load-bearing frame acts on the insertion rod, the weight of the load-bearing weight plate will be evenly pressed onto the high-temperature asphalt inside the crack due to the pressure booster.

[0015] In a preferred embodiment, the present invention may be further configured such that the cleaning mechanism also includes a pressure limiting member installed outside the main pile and a pin inserted into the protrusion at the bottom end of the main pile.

[0016] By adopting the above technical solution, and by making the desired holes inside the bottom protrusion and the pressurization assembly, the ground dust sweeper is inserted along the holes in the bottom protrusion and the holes inside the ground dust sweeper, so that the ground dust sweeper can be quickly replaced after significant wear.

[0017] In a preferred embodiment, the present invention may be further configured such that the transmission dust removal mechanism includes a telescopic rod connected to the outside of the housing, a safety outer box installed at the bottom of the telescopic rod, a sliding tube movably inserted into the inner side of the safety outer box, a transmission component built into the inner cavity of the safety outer box, and a linkage component meshing in the middle of the transmission component.

[0018] By adopting the above technical solution, a sliding tube is movably inserted into the safety outer box, and a linkage is movably installed on the inner side of the sliding tube. Under the auxiliary load-bearing and support of the sliding tube, the linkage will not vibrate when the ground sweeping component rotates.

[0019] In a preferred embodiment, the present invention may be further configured such that the transmission dust removal mechanism further includes an auxiliary component adapted to be inserted into the slide groove at the bottom of the slide bar, and a ground dust sweeping component movably connected to the bottom end of the auxiliary component.

[0020] By adopting the above technical solution and using an auxiliary component that can be movably installed in the inner groove of the slide bar, when the cracks on the asphalt pavement have different specifications and vary in width, the movement of the auxiliary component in the bottom groove of the slide bar can quickly control the dust removal component to treat the dust outside the cracks.

[0021] In a preferred embodiment, the present invention may be further configured such that the asphalt filling mechanism further includes a base mounted on both sides of the outer casing, a clip mounted on the outer side of the inner end of the base, a pulley assembly inserted into the inner side of the portable shaft, and a spring connected to the pulley assembly.

[0022] By adopting the above technical solution and using the pulley assembly, when asphalt repair work is required on larger cracks, the operator can control the outward extension of the pulley assembly by adjusting the screw at the outer end of the elastic core rod and the portable shaft, thereby improving the stability of the device.

[0023] In a preferred embodiment, the present invention can be further configured such that the flow aid is composed of a flow guide slider, a slider and a roller, and the two ends of the slider are equipped with springs connected to the inner cavity of the housing.

[0024] By adopting the above technical solution, using the flow aid installed movably in the inner cavity of the outer shell, when the high-temperature asphalt flows out from the bottom of the guide tube, it will slide down along the outside of the flow aid with the slope, aligned with the crack, under the influence of the rotation of the smoothing component. Combined with the two clamps limiting the flow guide slider, the waste of high-temperature asphalt material can be eliminated.

[0025] In a preferred embodiment, the present invention may be further configured such that: an annular toothed opening is provided on the outer side of the top end of the ground dust sweeping component, and the annular toothed opening at the top end of the ground dust sweeping component is adapted to the deflection gear at the outer end of the linkage component.

[0026] By adopting the above technical solution, an annular toothed opening is made on the outer side of the top of the ground dust sweeper, and a uniformly distributed brush is installed at the bottom of the ground dust sweeper. When the operator moves the device, the sliding of the outer wheel of the pulley assembly with the ground causes the transmission component, linkage component and ground dust sweeper to be driven in sequence. This allows the operator to clean and repair the cracks in the asphalt pavement at the same time.

[0027] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0028] 1. In this invention, as described above, since current asphalt pavement repair work requires a large amount of manual labor to carry out phased operations on the asphalt pavement, before treating the asphalt pavement, it is necessary to manually sweep the asphalt pavement to be repaired in order to reduce the impact of dust on the high-temperature asphalt, and the workload is huge. Therefore, by setting up a slide rail, and movably connecting the main pile inside the slide rail, and movably installing a sweeping head at the bottom of the main pile to clean the inside of the cracks on the asphalt pavement, and combining it with two ground dust sweeping parts to sweep the dust outside the asphalt cracks outward, the device can directly clean the asphalt pavement while repairing it, which greatly reduces the workload of repair personnel.

[0029] 2. In this invention, as described above, the device is installed on a handheld asphalt spraying device. When the sweeping mechanism, combined with the transmission dust removal mechanism, sweeps the asphalt pavement, it is necessary to reduce the waste of high-temperature asphalt material when filling cracks in the asphalt pavement. Therefore, by setting a smoothing component and fixing it in the outer shell using a base, the smoothing component is movably installed in the inner end of the base. A spring core rod is set inside the portable shaft to control the spring's adaptation to the cracks in the asphalt pavement. When high-temperature asphalt is sprayed out from the bottom of the guide pipe, the smoothing component contacts the ground and drives the flowing asphalt to compact and fill the cracks. This enables the efficient use of high-temperature asphalt and greatly reduces the waste of high-temperature asphalt material.

[0030] 3. In this invention, as described above, since the high-temperature asphalt cannot be directly flattened the moment it is installed in the crack, in order to prevent unevenness between the high-temperature asphalt and the asphalt pavement and to improve the flatness of the repaired area with the asphalt pavement, a load-bearing frame is set up, and a bag of fine sand and gravel is placed inside the load-bearing frame. When using it, the repair personnel need to cut a small groove on the bottom surface of the bottom bag of sand and gravel, and use the fine sand and gravel to spread the high-temperature asphalt on the asphalt crack along the surface of the load-bearing weight plate. In this way, while quickly flattening the high-temperature asphalt, the sand and gravel combined with the asphalt can be used to reinforce the repair of the crack in the asphalt pavement.

The load-bearing rolling mechanism 200 is mounted on the fixing mechanism 100, the sweeping mechanism 300 is fixedly connected to the outside of the fixing mechanism 100, the transmission dust removal mechanism 400 is fixedly mounted outside the fixing mechanism 100, and the asphalt filling mechanism 500 is mounted inside the fixing mechanism 100.

[0053] The fixing mechanism 100 includes a housing 110, a guide pipe 120, a slide bar 130, and a flow aid 140. The load-bearing flattening mechanism 200 includes a load-bearing frame 210, a crossbar 220, a pressure plate 230, a sand and gravel powder bag 240, a pressure boosting assembly 250, and a pressure plate assembly 260.

The pressure plate assembly 260 further includes a shaft 261, a limiting outer shaft 262, and a load-bearing weight plate 263. The cleaning mechanism 300 includes... The slide rail 310, bracket 320, main pile 330, pressure limiting component 340, sweeping head 350, and pin 360; the transmission dust removal mechanism 400 includes a safety outer box 410, telescopic rod 420, sliding tube 430, transmission component 440, linkage component 450, ground dust sweeping component 460, and auxiliary component 470; the asphalt filling mechanism 500 includes a base 510, smoothing component 520, clamping plate 530, portable shaft 540, elastic core rod 550, pulley assembly 560, and spring 570.

[0054] Specifically, the fixing mechanism 100 includes a flow aid 140 for guiding the flow of high-temperature asphalt; the load-bearing leveling mechanism 200 includes a stabilizing part and a pressure plate assembly 260; the pressure plate assembly 260 includes a shaft 261, a load-bearing weight plate 263 movably mounted on the shaft 261, and a limiting outer shaft 262 mounted on the shaft 261; the sweeping mechanism 300 includes a slide rail 310, a bracket 320 mounted inside the slide rail 310, a main pile 330 mounted inside the bracket 320, and a sweeping head 3 connected to the bottom end of the main pile 330. 50. The transmission dust removal mechanism 400 is installed on both sides of the outside of the fixed mechanism 100. The asphalt filling mechanism 500 includes a smoothing part 520 for rolling high-temperature asphalt, a portable shaft 540 built into the cavity of the smoothing part 520, and a spring core rod 550 connected in the portable shaft 540. The overall adaptability of the device to the crack is adjusted according to the gap of the crack on the asphalt pavement. Then the operator needs to control the device and move it backward so that the sweeping head 350 is located inside the crack and the two ground dust sweeping parts 460 are located on both sides of the crack.

[0055] Example 2:

[0056] Combination Figure 10As shown, in the above embodiment, the bottom end of the guide tube 120 is located in the middle of the smoothing member 520. When the smoothing member 520 moves along the ground, the high-temperature asphalt is smoothed by the smoothing member 520 and crushed to the inside of the crack. After the high-temperature asphalt flows out from the bottom end of the guide tube 120, it is affected by the rotation of the smoothing member 520 and slides down along the outside of the ramped flow aid 140 towards the crack. Combined with the limiting of the flow guide slider by the two clamps 530, the waste of high-temperature asphalt material can be avoided. The fixing mechanism 100 also includes a housing 110, a guide tube 120 installed in the housing 110, and a slide bar 130 connected to the two sides of the outside of the housing 110. The flow aid 140 is composed of a flow guide slider, a slide member, and a roller. Springs connected to the inner cavity of the housing 110 are installed at both ends of the slide member.

[0057] Example 3:

[0058] Combination Figure 4 and 5 As shown in the above embodiment, the fine sand and gravel packaged inside the sand and gravel powder bag 240 is evenly spread on the surface of the load-bearing weight plate 263 onto the crack. At this time, the device can directly roll onto the crack and quickly flatten the overall flatness of the asphalt pavement at the repair location. The pressure booster 252 is fixedly installed on the annular protrusion on the outer side of the sleeve 251. When the weight of the entire load-bearing frame 210 acts on the insertion rod 253, under the action of the pressure booster 252, the weight of the load-bearing weight plate 263 will evenly roll onto the inner side of the crack. On the high-temperature asphalt, the negative stabilizing part includes a load-bearing frame 210 connected to the outer shell 110, a crossbar 220 installed on the load-bearing frame 210, a pressure plate 230 movably connected to the load-bearing frame 210, a sand and gravel powder bag 240 built into the inner side of the load-bearing frame 210, and a pressure boosting assembly 250 installed at the bottom of the load-bearing frame 210. The pressure boosting assembly 250 also includes a sleeve 251 inserted into the shaft 261, a pressure boosting component 252 installed outside the sleeve 251, and a plug rod 253 movably connected to the inner cavity of the sleeve 251.

[0059] Example 4:

[0060] Combination Figure 7 As shown, in the above embodiment, the ground sweeping component 460 is inserted along the protruding hole at the bottom of the main pile 330 and the hole inside the ground sweeping component 460, so that the ground sweeping component 460 can be quickly replaced after significant wear. The cleaning mechanism 300 also includes a pressure limiting component 340 installed outside the main pile 330 and a pin 360 inserted into the protrusion at the bottom of the main pile 330.

[0061] Example 5:

[0062] Combination Figure 8As shown in the above embodiment, a uniformly distributed brush is added to the bottom end of the ground sweeping component 460. When the operator moves the device, the outer wheel of the pulley assembly 560 slides against the ground, thereby sequentially driving the transmission component 440, the linkage component 450, and the ground sweeping component 460. This allows the operator to clean and repair cracks in the asphalt pavement simultaneously. The linkage component 450 is movably installed inside the sliding tube 430. Supported by the sliding tube 430, the linkage component 450 prevents vibration when driving the ground sweeping component 460 to rotate. When cracks on the asphalt pavement vary in size and width, the movement of the auxiliary component 470 along the bottom groove of the sliding rod 130 is utilized. The ground dust sweeping component 460 can quickly control the treatment of dust outside the cracks. The transmission dust removal mechanism 400 includes a telescopic rod 420 connected to the outside of the housing 110, a safety outer box 410 installed at the bottom of the telescopic rod 420, a sliding tube 430 movably inserted into the inside of the safety outer box 410, a transmission component 440 built into the inner cavity of the safety outer box 410, and a linkage component 450 meshing in the middle of the transmission component 440. The transmission dust removal mechanism 400 also includes an auxiliary component 470 adapted to be inserted into the bottom sliding groove of the slide rod 130, and a ground dust sweeping component 460 movably connected to the bottom of the auxiliary component 470. The outer side of the top of the ground dust sweeping component 460 is provided with an annular toothed opening, and the annular toothed opening at the top of the ground dust sweeping component 460 is adapted to the deflection gear at the outer end of the linkage component 450.

[0063] Example 6:

[0064] Combination Figure 11 As shown in the above embodiment, when it is necessary to perform asphalt repair work on larger cracks, the operator can control the outward extension of the pulley assembly 560 by adjusting the spring core rod 550 and the screw at the outer end of the portable shaft rod 540, thereby improving the stability of the device. The asphalt filling mechanism 500 also includes a base 510 installed on both sides of the outer side of the housing 110, a clip 530 installed on the outer side of the inner end of the base 510, a pulley assembly 560 inserted into the inner side of the portable shaft rod 540, and a spring 570 connected to the pulley assembly 560.

[0065] Working principle and usage process of this invention:

[0066] Before use: Since current asphalt pavement repair work is all done manually, the irregularity of cracks in asphalt pavements makes manual work more precise. Conventional methods of spraying or using molds to repair asphalt pavement cracks make it difficult to fill the cracks with high-temperature asphalt and its inherent adhesive properties. Furthermore, dust inside the cracks hinders the bonding of the high-temperature asphalt material with the pavement itself. To improve the integrated filling process of high-temperature asphalt and reduce the impact of dust inside the cracks on the high-temperature asphalt, operators need to select and install a sweeper based on the specifications of the cracks in the asphalt pavement. When a single or multiple cracks appear on the asphalt pavement, the operator needs to movably insert multiple main piles 330 connected with sweeping heads 350 and brackets 320 into the inner side of the slide rail 310 according to the row spacing between the cracks. Then, by adjusting the nuts at the top of the main piles 330, the cleaning of the inner side of the asphalt crack by the main piles 330 and sweeping heads 350 is increased. When the dust inside the crack is swept to the outer side of the asphalt pavement, it is driven by the pulley assembly 560. At this time, the teeth on the inner side of the pulley assembly 560 will drive the transmission component 440 and the linkage component 450 to rotate in sequence. Then, the ground dust sweeping component 460 is driven to sweep the dust outside the crack away.

[0067] Before use: After completing the above operations, the operator needs to place the sand and gravel powder bag 240 containing fine sand and gravel on the inner side of the load-bearing frame 210 in sequence. Then, according to the size of the crack, the operator needs to use a knife to cut the sand and gravel powder bag 240 located at the bottom of the inner side of the load-bearing frame 210 along its bottom. The size of the groove at the bottom of the sand and gravel powder bag 240 is controlled according to the size of the crack. When the fine sand and gravel are evenly spread on the surface of the high-temperature asphalt along the surface of the load-bearing weight plate 263, they are flattened by the pressure of the load-bearing weight plate 263, which can quickly flatten the cracked part containing high-temperature asphalt and the asphalt pavement as a whole.

[0068] In use: The operator needs to hold the handle at the bottom of the guide tube 120 and move it along the crack in the asphalt pavement. At this time, the operator needs to move backward and rotate the device according to the changes in the crack to keep the smoothing part 520 in contact with the crack. Then, the operator needs to select and replace the load-bearing weight plate 263 with different weights according to the width of the crack to compact the crack of different widths.
