Abstract
Description
Technical Field
[0001] This invention relates to the field of pothole filling and maintenance technology, specifically to a pothole filling and maintenance device for roads and bridges. Background Technology
[0002] Under the long-term heavy pressure of vehicles, potholes are easily formed on the road surface, and timely repair of potholes is necessary to ensure that the road can be passed normally.
[0003] In existing technologies, when filling and compacting potholes, the filling equipment is usually used to fill the pothole with filler material first, and then compaction is carried out. This is not convenient for filling and compacting the pothole at the same time, thus reducing work efficiency. Moreover, when the pothole depth is greater than 5 cm, two filling and two compaction processes are required. During the first filling and compaction, since the filler material is located in the pothole, if a compaction equipment with a large compaction area is used, it can only press on the road surface and cannot compact the filler material in the pothole. If a compaction equipment with a small compaction area is used, it is necessary to move the compaction equipment back and forth and left and right, which increases the operation time. Therefore, we propose a pothole filling and maintenance device for roads and bridges. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting a leveling unit, allows the mixing assembly to rotate in the opposite direction when filling pits, causing the filling material to fall between two first connecting plates. The filling material is then diverted by a guiding assembly. At this time, an external control switch starts the first motor, which drives one of the screw rods to rotate. Since the screw rod and the guide rod are slidably connected, and the rotating shaft fixed to the guide rod is rotatably connected to the limiting plate, when one screw rod rotates, the other screw rod will also rotate synchronously. The filling material is placed on the two screw rods respectively, allowing the filling material to be conveyed from both sides to the middle, thereby achieving the effect of leveling the filling material. Furthermore, the two first concave plates can be moved to opposite sides or to the opposite side to adjust the feeding range of the filling material, thus enabling the filling of pits of different widths.
[0016] 2. This invention, by setting a compaction unit, simultaneously moves the second concave plate when the first concave plate is moved, so that one side of the first concave plate and one side of the first fixed block are on the same vertical line. During compaction, the adjusting plate moves downward, causing the first fixed block to move downward. When the adjusting plate moves downward, it causes the first telescopic rod to extend, and the tension spring to stretch. After the pressing block hammers the filling material, the tension spring causes the adjusting plate to move in the opposite direction, thereby achieving the effect of resetting the adjusting plate. Then, the adjusting plate is moved up and down multiple times to achieve the effect of compacting the filling material. Attached Figure Description

Detailed Implementation
[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1: Please refer to Figures 1-10This invention provides a technical solution: a filling and maintenance device for road and bridge potholes, including a mobile frame 1, a mixing assembly 11 on the top of the mobile frame 1, a mounting frame 12 fixedly connected to the top of the mobile frame 1, a material guide shell 13 fixedly connected to the inner wall of the mounting frame 12, and a filling and maintenance mechanism 2 on one side of the mobile frame 1. The filling and maintenance mechanism 2 includes a leveling unit 21 and a compaction unit 22. The compaction unit 22 is located on one side of the leveling unit 21, and a striking mechanism 3 is also located on one side of the leveling unit 21. It should be noted that the mixing assembly 11 consists of a mixing tank and a transmission component. The transmission component is used to drive the mixing tank to rotate. When the mixing tank rotates in the forward direction, the mixing tank is in a mixing state, and when the mixing tank rotates in the reverse direction, the filler material in the mixing tank can be discharged. This is prior art and will not be elaborated further.
[0021] The leveling unit 21 includes two first connecting plates 2101 disposed on one side of the movable frame 1. A limiting plate 2102 is fixedly connected between the opposite sides of the two first connecting plates 2101. Two first concave plates 2103 are slidably connected to the surfaces of the two first connecting plates 2101. A rotating shaft 2104 is rotatably connected to the inner cavity of the limiting plate 2102. Guide rods 2105 are fixedly connected to both ends of the rotating shaft 2104. A spiral rod 2106 is rotatably connected to the inner wall of the first concave plate 2103. The opposite ends of the two spiral rods 2106 are respectively connected to the guide rods 2105. The surface is slidably connected. A first motor 2107 is fixedly connected to one side of one of the first concave plates 2103. The output end of the first motor 2107 passes through the first concave plate 2103 and is fixedly connected to one end of one of the spiral rods 2106. A guide assembly is provided between the opposite sides of the two first connecting plates 2101. A groove 2108 is provided at the bottom of the first connecting plate 2101. The guide assembly is used to guide the filling material. By setting the leveling unit 21, when filling the pit, the stirring assembly 11 is rotated in the opposite direction, so that the filling material falls on the two first connecting plates 2101. Between the connecting plates 2101, the filling material is diverted by a guide assembly. At this time, an external control switch starts the first motor 2107, causing it to drive one of the spiral rods 2106 to rotate. Since the spiral rod 2106 is slidably connected to the guide rod 2105, and the rotating shaft 2104 fixed to the guide rod 2105 is rotatably connected to the limiting plate 2102, when one spiral rod 2106 rotates, the other spiral rod 2106 will also rotate synchronously, and the filling material will fall onto the two spiral rods 2106 respectively. On 106, the filling material is conveyed from both sides to the middle, thereby achieving the effect of flattening the filling material. The two first concave plates 2103 can be moved to opposite sides to adjust the feeding range of the filling material, so as to fill the pits of different widths. It should be noted that the purpose of the groove 2108 is to ensure that when flattening, the filling material is conveyed from both sides to the middle and accumulates in the middle position, so that the filling material is higher in the middle and lower on both sides. The slightly higher design in the middle can disperse the effect of uneven settlement.
[0022] The guiding assembly includes a guide plate 2109 slidably connected between two first connecting plates 2101 on opposite sides. A metal elastic sheet 2110 is fixedly connected between the opposite sides of the two guide plates 2109. A guide groove 2111 is provided on each opposite side of the two first connecting plates 2101. Guide blocks 2112 that are slidably connected to the guide grooves 2111 are fixedly connected to both sides of the guide plate 2109. By using the guide plate 2109, the metal elastic sheet 2110 and the guide grooves 2111 in cooperation, when the two first concave plates 2103 are moved to opposite sides, the metal elastic sheet 2110 is moved upwards at the same time. This will drive the guide block 2112 to move horizontally in the cavity of the guide groove 2111, thereby achieving the effect of adjusting the gap between the guide plate 2109 and the first concave plates 2103.
[0023] One of the first connecting plates 2101 is fixedly connected to one side of a first hydraulic rod 2113. The telescopic end of the first hydraulic rod 2113 is fixedly connected to a moving plate 2114. The bottom of the moving plate 2114 is fixedly connected to a sliding rod 2115. One end of the sliding rod 2115 is fixedly connected to a round rod 2116. The surface of the sliding rod 2115 is slidably connected to the inner wall of the first connecting plate 2101, and the surface of the round rod 2116 is fixedly connected to the bottom of the metal elastic sheet 2110. By setting up the first hydraulic rod 2113, the moving plate 2114, and the sliding rod 2115 in cooperation, the first hydraulic rod 2113 is activated by an external control switch. The telescopic end of the first hydraulic rod 2113 drives the moving plate 2114 and the sliding rod 2115 to move, so that the sliding rod 2115 slides in the inner cavity of the first connecting plate 2101. At this time, the round rod 2116 will drive the metal elastic sheet 2110 to move, thereby achieving the effect of adjusting the angle of the guide plate 2109.
[0024] The specific implementation of this embodiment is as follows: When filling the pit, the stirring assembly 11 is rotated in the opposite direction, causing the filling material to fall between the two first connecting plates 2101. The filling material is diverted by the guiding assembly. At this time, the first motor 2107 is started by an external control switch, causing the first motor 2107 to drive one of the screw rods 2106 to rotate. Since the screw rod 2106 is slidably connected to the surface of the guide rod 2105, and the rotating shaft 2104 fixed to the guide rod 2105 is rotatably connected to the limiting plate 2102, when one screw rod 2106 rotates, the other screw rod 2106 will also rotate synchronously. The filling material is respectively placed on the two screw rods 2106, so that the filling material is conveyed from both sides to the middle, thereby realizing the filling material... The device achieves a flattening effect and allows the two first concave plates 2103 to be moved to opposite sides, thereby adjusting the feeding range of the filling material. This allows for filling of pits of different widths. When the two first concave plates 2103 are moved to opposite sides, the first hydraulic rod 2113 is activated by an external control switch. The telescopic end of the first hydraulic rod 2113 drives the moving plate 2114 and the sliding rod 2115 to move, causing the sliding rod 2115 to slide in the inner cavity of the first connecting plate 2101. At this time, the round rod 2116 drives the metal elastic sheet 2110 to move upward, which in turn drives the guide block 2112 to move horizontally in the inner cavity of the guide groove 2111, thereby adjusting the gap between the guide plate 2109 and the first concave plate 2103.
[0025] Example 2: Please refer to Figures 1-10 The present invention provides a technical solution: a device for filling and maintaining potholes in roads and bridges. The present invention makes corresponding improvements to address the technical problems mentioned in the background art.
[0026] The compaction unit 22 includes two second connecting plates 2201. A fixing plate 2202 is fixedly connected to the top of both second connecting plates 2201. A fixing bracket 2203 is provided between the second connecting plates 2201 and the opposite side of the first connecting plate 2101. It should be noted that one side of the fixing bracket 2203 is fixedly connected to the second connecting plate 2201, and another side of the fixing bracket 2203 is slidably connected to the first connecting plate 2101. Two second concave plates 2204 are slidably connected to the surfaces of both second connecting plates 2201. A sliding frame 2205 is slidably connected between opposite sides. A first telescopic rod 2206 is fixedly connected to the bottom of the sliding frame 2205. A tension spring 2207 is sleeved on the surface of the first telescopic rod 2206. One end of the tension spring 2207 is fixedly connected to the sliding frame 2205, and the other end of the tension spring 2207 is fixedly connected to the adjusting plate 2208. The telescopic end of the first telescopic rod 2206 is fixedly connected to the adjusting plate 2208. Two first fixing blocks 2210 are slidably connected to the bottom of the adjusting plate 2208, and a second telescopic rod is fixedly connected to the bottom of the first fixing blocks 2210. 2211, a lower pressure block 2212 is fixedly connected to the telescopic end of the second telescopic rod 2211, and a spring 2213 is fixedly connected to the bottom of the first fixed block 2210. One end of the spring 2213 is fixedly connected to the lower pressure block 2212, and the spring 2213 is sleeved on the surface of the second telescopic rod 2211. By setting the compaction unit 22, when the first concave plate 2103 is moved, the second concave plate 2204 is moved synchronously, so that one side of the first concave plate 2103 and one side of the first fixed block 2210 are on the same vertical line, and compaction is performed. When the adjusting plate 2208 is moved downward, it causes the first fixed block 2210 to move downward. When the adjusting plate 2208 moves downward, it causes the first telescopic rod 2206 to extend, and the tension spring 2207 to stretch. After the pressing block 2212 hammers the filling material, the tension spring 2207 causes the adjusting plate 2208 to move in the opposite direction, thereby achieving the effect of resetting the adjusting plate 2208. Then, the adjusting plate 2208 is moved up and down multiple times to achieve the effect of compacting the filling material.
[0027] A clamping plate 2214 is fixedly connected to the bottom of the sliding frame 2205. A second motor 2215 is fixedly connected to one side of the clamping plate 2214. The output end of the second motor 2215 passes through the clamping plate 2214 and is fixedly connected to an eccentric wheel 2216. The surface of the eccentric wheel 2216 contacts the top of the adjusting plate 2208. By setting up the cooperation of the clamping plate 2214, the second motor 2215 and the eccentric wheel 2216, the second motor 2215 is started by an external control switch, so that the second motor 2215 drives the eccentric wheel 2216 to rotate. The rotation of the eccentric wheel 2216 will squeeze the adjusting plate 2208, thereby achieving the effect of reciprocating movement of the adjusting plate 2208.
[0028] A third motor 2217 is fixedly connected to the top of the fixed plate 2202. The output end of the third motor 2217 passes through the fixed plate 2202 and is fixedly connected to a threaded rod 2218. The surface of the threaded rod 2218 is threadedly connected to the inner wall of the sliding frame 2205. Slider 2219 is fixedly connected to the opposite side of the two first fixed blocks 2210. The surface of the slider 2219 is slidably connected to the inner wall of the second concave plate 2204. By setting the third motor 2217 and the threaded rod 2218 to work together, the third motor 2217 is started by an external control switch, so that the third motor 2217 drives the threaded rod 2218 to rotate. The threaded rod 2218 is threadedly connected to the inner wall of the sliding frame 2205, thereby achieving the effect of driving the sliding frame 2205 to move downward, thereby adjusting the distance between the lower pressure block 2212 and the ground.
[0029] A fourth motor 2220 is fixedly connected to the top of the fixed frame 2203. The output end of the fourth motor 2220 extends through the inner wall of the fixed frame 2203 and is fixedly connected to a first gear 2221. Long plates 2222 are fixedly connected to opposite sides of the two second concave plates 2204. The side of the long plate 2222 closest to the first concave plate 2103 is slidably connected to the first concave plate 2103. Toothed plates 2223 are fixedly connected to opposite sides of the two long plates 2222. The toothed plates 2223 mesh with the first gear 2221, and the surface of the toothed plates 2223 is slidably connected to the inner wall of the fixed frame 2203. This is achieved by setting the fourth motor 2220... The first gear 2221, the toothed plate 2223, and the long plate 2222 work together to start the fourth motor 2220 using an external control switch. The fourth motor 2220 drives the first gear 2221 to rotate, which in turn causes the first gear 2221 to move the two toothed plates 2223 to opposite sides. The toothed plates 2223 then move the long plate 2222, which in turn moves the first concave plate 2103 and the second concave plate 2204 synchronously. This achieves the effect of simultaneously adjusting the distance between the two first concave plates 2103 and the distance between the two second concave plates 2204.
[0030] A fixed rod 2224 is fixedly connected to one side of the movable frame 1. An adapter rod 2225 is fixedly installed at one end of the fixed rod 2224 by bolts. The bottom of the adapter rod 2225 is fixedly connected to the top of the second connecting plate 2201. A limiting plate 2226 is fixedly connected between the opposite sides of the two first connecting plates 2101. A second hydraulic rod 2209 is fixedly connected to the top of the adapter rod 2225. The output end of the second hydraulic rod 2209 extends through to the bottom of the adapter rod 2225 and is fixedly connected to the top of the limiting plate 2226. By setting up the fixed rod 2224, the adapter rod 2225 and the second hydraulic rod 2209 in cooperation, when filling a pit with a depth greater than 5 cm, the second hydraulic rod 2209 is activated by an external control switch. This causes the second hydraulic rod 2209 to move the limiting plate 2226 downward. The limiting plate 2226 then moves the first connecting plate 2101 downward, allowing the first connecting plate 2101 to enter the pit, thus facilitating the filling of the filling material.
[0031] The specific implementation of this embodiment is as follows: The fourth motor 2220 is started using an external control switch, causing the fourth motor 2220 to drive the first gear 2221 to rotate. This causes the first gear 2221 to drive the two toothed plates 2223 to move to opposite sides. The toothed plates 2223 then drive the long plate 2222 to move, and the long plate 2222 drives the first concave plate 2103 and the second concave plate 2204 to move synchronously. This achieves the simultaneous adjustment of the distance between the two first concave plates 2103 and the distance between the two second concave plates 2204. The distance between 2204 has the effect of simultaneously moving the second concave plate 2204 when the first concave plate 2103 is moved. At this time, one side of the first concave plate 2103 and one side of the first fixed block 2210 are on the same vertical line. During compaction, the second motor 2215 is started by an external control switch, causing the second motor 2215 to drive the eccentric wheel 2216 to rotate. The rotation of the eccentric wheel 2216 will squeeze the adjusting plate 2208, causing the adjusting plate 2208 to move downward, so that the adjusting plate 22... When the first fixed block 2210 moves downward and the adjusting plate 2208 moves downward, the first telescopic rod 2206 extends, and the tension spring 2207 stretches. After the pressing block 2212 hammers the filling material, the tension spring 2207 causes the adjusting plate 2208 to move in the opposite direction, thus achieving the effect of resetting the adjusting plate 2208. Then, the adjusting plate 2208 is moved up and down repeatedly to achieve the effect of compacting the filling material. When filling pits with a depth greater than 5 cm, this method is effective. The second hydraulic rod 2209 is activated by an external control switch, causing the second hydraulic rod 2209 to move the limiting plate 2226 downward. The limiting plate 2226 then moves the first connecting plate 2101 downward, allowing the first connecting plate 2101 to enter the pit, thus facilitating the filling of the filling material. It should be noted that after compacting the two sides of the top of the pit, the two first fixing blocks 2210 need to be moved to the opposite side so that the two first fixing blocks 2210 contact each other, thereby compacting the middle position of the pit again.
[0032] Example 3: Please refer to Figures 1-10 The present invention provides a technical solution: a device for filling and maintaining potholes in roads and bridges. The present invention makes corresponding improvements to address the technical problems mentioned in the background art.
[0033] The striking mechanism 3 includes a drive shaft 301 rotatably connected to the inner cavity of the limiting plate 2102. A first bevel gear 302 is fixedly connected to the surface of the drive shaft 2104. A second bevel gear 303 meshing with the first bevel gear 302 is fixedly connected to one end of the drive shaft 301. An adjusting rod 304 is threadedly connected to the other end of the drive shaft 301. An elastic rod 305 is fixedly connected to one end of the adjusting rod 304. An impact block 306 is fixedly connected to one end of the elastic rod 305. By setting the striking mechanism 3, when the drive shaft 2104 is rotated, the first bevel gear 302 will be driven to rotate. The first bevel gear 302 will drive the second bevel gear 303 to rotate, causing the adjusting rod 304 to rotate. This causes the impact block 306 to impact the first connecting plate 2101, thereby causing the first connecting plate 2101 to vibrate. The vibration is transmitted to the guide plate 2109, thus facilitating the guidance of the filling material.
[0034] The specific implementation of this embodiment is as follows: When the rotating shaft 2104 is rotated, it will drive the first bevel gear 302 to rotate, and the first bevel gear 302 will drive the second bevel gear 303 to rotate, causing the adjusting rod 304 to rotate, causing the impact block 306 to impact the first connecting plate 2101. During the impact, the elastic rod 305 will deform under force, thereby causing the first connecting plate 2101 to vibrate. The vibration is transmitted to the guide plate 2109, which facilitates the guidance of the filling material. It should be noted that the adjusting rod 304 is threadedly connected to the transmission shaft 301, indicating that the adjusting rod 304 is detachable and the adjusting rod 304, elastic rod 305 and impact block 306 can be replaced.
