Description

Technical Field

[0001] This utility model belongs to the field of highway and bridge maintenance, specifically, it relates to a construction device for highway pavement and bridge deck maintenance. Background Technology

[0002] In a narrow sense, highway and bridge maintenance refers to the inspection, testing, evaluation, repair, and reinforcement work carried out to ensure that highways and bridges are always in normal working condition, so as to maintain the road's performance. Repair and reinforcement work involves taking timely measures to repair damaged parts, ensuring driving safety, comfort, and smooth flow, and saving transportation costs and time. When repairing cracks in highway pavement and bridge decks, water spraying devices are often used to wash the cracks in the pavement and bridge decks clean, preventing dust and impurities in the cracks from affecting the effectiveness of the maintenance work.

[0003] Chinese Patent Publication No. CN220284630U discloses a bridge maintenance construction device, including a base, a water tank fixedly connected to one side of the top of the base, an inlet on one side of the top of the water tank, a filter screen fitted on the inner wall of the inlet, a connector fitted at the top of the inner wall of the inlet, a sealing ring fixedly connected to the bottom edge of the connector, and the bottom of the sealing ring abutting against the edge of the filter screen, an inlet pipe fixedly connected to the top of the connector, and the inner wall of the inlet pipe communicating with the inner wall of the connector, a fixing screw sleeve fitted on the outer wall of the inlet pipe, and the inner wall of the fixing screw sleeve threadedly connected to the top of the outer wall of the inlet. Although the aforementioned bridge maintenance construction device effectively filters impurities of all sizes from the water source by incorporating a filter screen at the inlet, thus improving the reliability of the booster pump during bridge maintenance, the device directly fills the damaged gaps after washing the road surface and bridge deck. Since moisture remains in these gaps after washing, it affects the effectiveness of the maintenance work. Furthermore, the filter screen is stuck to the inner wall of the inlet, requiring a clamping tool to remove and replace it, thus failing to provide tool-free replacement.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a road surface and bridge deck maintenance construction device, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A road surface and bridge deck maintenance construction device includes: a base, on which a water tank, a hot air drying component and a crack filling component are installed. A pressure pump is connected to one side of the water tank. A connecting pipe is installed on the outlet of the pressure pump. A high-pressure water gun is connected to the end of the connecting pipe. The high-pressure water gun can spray a very fine water jet for washing cracks or other defects on the road surface and bridge deck.

[0008] The water tank is equipped with an inlet cylinder on the upper side, and a filter element is installed inside the inlet cylinder. A fixing bracket that limits the positioning of the filter element is installed inside the inlet cylinder. A groove is opened on the upper side of the fixing bracket, and a squeezing rod is slidably fitted in the groove. At least two symmetrically arranged elastic buckles are installed at the bottom of the squeezing rod. A clip that engages with the elastic buckles is installed between the squeezing rod and the groove. The squeezing rod is elastically fitted on the upper side of the clip.

[0009] Optionally, the elastic buckle includes an elastic rod installed at the bottom of the extrusion rod and a locking block installed at the end of the elastic rod, the locking block having a triangular structure; the locking component includes a first fixed seat, a second fixed seat installed at the bottom of the groove, a fixed rod installed between the first fixed seat and the second fixed seat, and a movable ring slidably engaged with the fixed rod and locking with the locking block; an elastic telescopic rod is installed between the first fixed seat and the extrusion rod, and the upper and lower sides of the movable ring are provided with chamfers that cooperate with the locking block.

[0010] Optionally, the hot air drying assembly includes a hot air blower mounted on the upper side of the base, an opening on the lower side of the base corresponding to the hot air blower, a telescopic corrugated pipe mounted on the air outlet of the hot air blower, and a blower nozzle mounted on the end of the telescopic corrugated pipe. A support frame corresponding to the blower nozzle is installed inside the opening. The hot air blown out by the hot air drying assembly can dry the residual moisture in the gaps of the road surface and bridge deck, thereby improving the effect of road surface and bridge deck maintenance construction.

[0011] Optionally, the joint filling assembly includes a material tank mounted on the upper side of the base, a motor mounted on the upper side of the material tank, a stirring roller rotatably fitted inside the material tank and fixedly connected to the output end of the motor, a discharge nozzle mounted on one side of the base, a material pump mounted on one side of the material tank, a material pipe connected between the discharge port of the material pump and the discharge nozzle, and an electric heating plate mounted inside the material tank. The material pump discharges the joint filling liquid in the material tank through the material pipe and the discharge nozzle into the gaps of the road surface and bridge deck, which facilitates filling the gaps of the road surface and bridge deck.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0013] By using a hot air drying component installed on the base, the water in the tank is sprayed out by a high-pressure water gun after the pressure pump is activated to wash various cracks in the road surface and bridge deck. After the hot air blown out by the hot air drying component dries the residual moisture in the cracks of the road surface and bridge deck, the cracks can then be filled. This improves the effectiveness of road and bridge maintenance. With the set elastic buckles and clips, when the filter element needs to be removed, pressing the filter element will release the squeezing rod from the clips through the elastic buckles. The squeezing rod will then push the filter element out of the inlet cylinder, allowing the filter element to be directly removed from the inlet cylinder for replacement, thus reducing the need to use tools to replace the filter element.

[0024] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Please see Figure 1-5 As shown, this embodiment provides a road surface and bridge deck maintenance construction device, including: a base 1, on which a water tank 2, a hot air drying component 8 and a crack filling component 9 are mounted. A pressure pump 4 is connected to one side of the water tank 2. A connecting pipe 6 is installed on the outlet of the pressure pump 4. A high-pressure water gun is connected to the end of the connecting pipe 6. The high-pressure water gun can spray a very fine water jet for washing cracks or other defects on the road surface and bridge deck. Multiple casters are installed on the lower side of the base 1. The casters are casters with self-locking function in the prior art. A handle 5 is installed on one side of the base 1 near the water tank 2 to facilitate the movement of this device.

[0027] The water tank 2 has an inlet cylinder 3 on its upper side, and a filter element 7 is installed inside the inlet cylinder 3. A fixing bracket 10 is installed inside the inlet cylinder 3 to limit the filter element 7. A groove is opened on the upper side of the fixing bracket 10, and a squeezing rod 11 is slidably fitted in the groove. At least two symmetrically arranged elastic buckles 12 are installed at the bottom of the squeezing rod 11. A locking piece 14 is installed between the squeezing rod 11 and the groove to engage with the elastic buckles 12. The squeezing rod 11 is elastically fitted on the upper side of the locking piece 14. The filter element 7 can be a water filter or an RO membrane in the prior art. The RO membrane is a high-precision filter that can effectively filter inorganic salts, heavy metal ions, etc. in the water source and desalinate the water. The water filter is a coarse filter that can effectively filter impurities in the water source.

[0028] By using the hot air drying component 8 installed on the base 1, the water in the water tank 2 can be sprayed out by the high-pressure water gun after the pressure pump 4 is started to wash the various cracks on the road surface and bridge deck. After the hot air blown out by the hot air drying component 8 can dry the residual moisture in the cracks of the road surface and bridge deck, the cracks can then be filled. This improves the effect of road and bridge maintenance. With the elastic buckle 12 and the locking piece 14, when the filter element 7 needs to be removed, the filter element 7 is pressed, and the squeezing rod 11 is released from the locking piece 14 through the elastic buckle 12. The squeezing rod 11 pushes the filter element 7 out of the liquid inlet cylinder 3 through elasticity, so that the filter element 7 can be directly removed from the liquid inlet cylinder 3 for replacement, thereby reducing the need to use tools to replace the filter element 7.

[0029] like Figure 4-5As shown, the elastic buckle 12 of this embodiment includes an elastic rod 1201 installed at the bottom of the pressing rod 11 and a locking block 1202 installed at the end of the elastic rod 1201. The locking block 1202 has a triangular structure. The locking member 14 includes a first fixed seat 1401, a second fixed seat 1403 installed at the bottom of the groove, a fixed rod 1402 installed between the first fixed seat 1401 and the second fixed seat 1403, and a movable ring 1404 that slides around the fixed rod 1402 and engages with the locking block 1202. An elastic telescopic rod 13 is installed between the first fixed seat 1401 and the pressing rod 11. The upper and lower sides of the movable ring 1404 are provided with chamfers that cooperate with the locking block 1202.

[0030] When the filter element 7 needs to be removed from the inlet cylinder 3 for replacement, press the filter element 7. The filter element 7 squeezes the squeezing rod 11 to move. The movement of the squeezing rod 11 drives the elastic rod 1201 to move. The movement of the elastic rod 1201 drives the locking block 1202 to move. The locking block 1202 engages with the movable ring 1404 through the inclined surface of the triangle. When the filter element 7 is released, the locking block 1202 resets due to the elastic force of the elastic telescopic rod 13. When the locking block 1202 resets, it drives the movable ring 1404 to move to the first fixed seat 1. At position 401, the first fixed seat 1401 limits the movable ring 1404. The locking block 1202 is disengaged from the movable ring 1404 by chamfering and slides out of the first fixed seat 1401. The sliding out of the first fixed seat 1401 allows the squeezing rod 11 to be fully reset by the elastic force of the elastic telescopic rod 13. The reset of the squeezing rod 11 pushes the filter element 7 out of the liquid inlet cylinder 3, so that the filter element 7 can be directly removed from the liquid inlet cylinder 3 for replacement, thereby reducing the need to use tools to replace the filter element 7.

[0031] like Figure 3 As shown, the hot air drying assembly 8 of this embodiment includes a hot air blower 801 mounted on the upper side of the base 1, an opening on the lower side of the base 1 corresponding to the hot air blower 801, a telescopic corrugated pipe 802 mounted on the air outlet of the hot air blower 801, and a blower nozzle 803 mounted on the end of the telescopic corrugated pipe 802. A support frame corresponding to the blower nozzle 803 is installed in the opening, wherein the support frame supports and places the blower nozzle 803, and the blower nozzle 803 extends out of the opening through the telescopic corrugated pipe 802.

[0032] When drying the residual moisture in the gaps of highway pavement and bridge deck, the hot air blower 801 is started. The hot air generated by the hot air blower 801 is blown out through the telescopic corrugated pipe 802 and the extendable nozzle 803, which can dry the residual moisture in the gaps of highway pavement and bridge deck, thereby improving the effect of highway and bridge maintenance construction.

[0033] like Figure 3As shown, the grouting assembly 9 in this embodiment includes a material tank 901 mounted on the upper side of the base 1, a motor 903 mounted on the upper side of the material tank 901, a stirring roller 902 rotatably fitted inside the material tank 901 and fixedly connected to the output end of the motor 903, a discharge nozzle 904 mounted on one side of the base 1, a material pump mounted on one side of the material tank 901, a material pipe 905 connected between the discharge port of the material pump and the discharge nozzle 904, and an electric heating plate mounted inside the material tank 901. The material tank 901 stores grouting liquid.

[0034] When it is necessary to fill the gaps in the road surface and bridge deck, the sealant is first put into the material tank 901. Then, the sealant in the material tank 901 is heated and softened by an electric heating plate. Then, the motor 903 drives the stirring roller 902 to stir the softened sealant in the material tank 901 evenly. At this time, the material pump is started, and the material pump discharges the sealant in the material tank 901 into the gaps in the road surface and bridge deck through the material pipe 905 and the discharge nozzle 904, so as to facilitate filling the gaps in the road surface and bridge deck.

[0035] The hot air blower 801 described in this embodiment can be a blower or hot air blower with a hot air blowing function in the prior art, and therefore is not specifically described in this document.

[0036] In this embodiment, the discharge nozzle 904 and the feed pipe 905 can be connected by a pipe structure or other existing pipe connection structures. The discharge nozzle 904 can be used to fill large areas of cracks and repair depressions or gaps on the surface of highways and bridges. Alternatively, the discharge nozzle 904 can be removed, and the feed pipe 905 can be used directly to fill small cracks on the surface of highways and bridges. Or, the filler can be introduced into a tank (such as a kettle-shaped heating pot) in the prior art through the feed pipe 905, and the small cracks on the surface of highways and bridges can be repaired manually.

[0037] This utility model has a compact and lightweight structure. When it is not carrying filling liquid or rinsing liquid, it can be lifted by only 2-4 people and placed on a transport vehicle for transportation. The device can be fixed on the transport vehicle by the self-locking casters at the bottom of the base 1.

[0038] This utility model provides a construction device for the maintenance of highway pavement and bridge deck, mainly for the maintenance of various cracks and defects on highway pavement and bridge deck, and can also be used for other defects such as potholes on highway pavement and bridge deck.

[0039] like Figure 3 As shown, the opening at the bottom of the hot air blower 801 in this embodiment can directly dry the residual moisture in the gaps of the road surface and bridge deck. Figure 3 This solution is not limited to a specific location and can also be set on the side so that the blower can be manually pulled to dry the area that needs to be dried.

[0040] like Figure 1 As shown, in this embodiment, a connecting pipe 6 is attached to one side of the water tank 2. A high-pressure water gun is connected to the end of the connecting pipe 6. The high-pressure water gun can spray a very fine water jet, which can wash away cracks or other defects in road surfaces and bridge decks. Figure 1 As an example only, this solution is not limited to a specific location. It can also be set on other sides of water tank 2 or opened in other locations of the device to facilitate manual handling of high-pressure water guns to wash road surfaces, bridge deck cracks or other defects.

[0041] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
