Description

Technical Field

[0001] This utility model relates to the field of concrete bridge deck paving curing technology, specifically to a spray curing device suitable for bridge deck paving of different widths. Background Technology

[0002] Bridge deck pavement is an important component of bridge structure, and its quality directly affects the service life of the bridge and traffic safety. Timely and effective curing after the concrete pavement is constructed can prevent cracks from forming due to rapid water loss, and improve the strength and durability of the concrete.

[0003] Traditional maintenance methods often involve manual watering, which is labor-intensive, inefficient, and uneven, making it difficult to ensure consistent maintenance results. Alternatively, covering with moisture-retaining materials can be used, but this requires a lot of manpower and materials, resulting in high costs, and the removal of the moisture-retaining materials can easily damage the concrete surface.

[0004] Therefore, to address the above problems, a spray curing device suitable for bridge deck pavement of different widths is proposed. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a spray curing device suitable for bridge decks of different widths. This invention enables the spray curing of bridge decks of different widths by connecting spray components of different numbers and positions, thereby reducing labor intensity and improving spraying quality and efficiency.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A spray curing device suitable for bridge deck pavement of different widths includes: several sets of spray components, which are evenly arranged on the bridge deck along its length and adjacent spray components are interconnected by connecting pipes; a water pump, the inlet of which is connected to a water tank and the outlet of which is connected to the spray components; each spray component includes a support frame, on which a spray pipe is mounted, a connector is mounted at the bottom of the spray pipe, and a telescopic pipe is coaxially and slidably connected to the top of the spray pipe, with the inner cavity of the spray pipe communicating with the inner cavity of the telescopic pipe, and a spray head is mounted at the top of the telescopic pipe.

[0008] Preferably, the support frame includes a support ring, which is sleeved on the outside of the spray pipe. Multiple support rods are evenly rotatably arranged on the outer side of the support ring. The end of the support rod away from the support ring is rotatably connected to one end of the ground rod, and the other end of the ground rod is rotatably connected to one end of the support rod. The other end of the support rod is rotatably connected to the support rod. The support rod, the ground rod, and the support rod are connected in a triangular shape as a whole.

[0009] Preferably, the support rod is provided with an external thread on the outside, and the end of the support rod away from the ground rod is rotatably connected to a fixing ring. The fixing ring is coaxially rotatably mounted on a sliding sleeve, and the sliding sleeve is threadedly connected to the support rod.

[0010] Preferably, the bottom of the ground pole is in close contact with the bridge surface, and several anti-slip grooves are provided on the bottom surface of the ground pole, with the length direction of the anti-slip grooves perpendicular to the length direction of the ground pole.

[0011] Preferably, the connecting pipe is a flexible hose containing steel wire to prevent it from getting knotted and deformed, and the outside of the hose is covered with a wear-resistant layer. Quick-connect recesses are provided at both ends of the connecting pipe.

[0012] Preferably, the connector includes a connecting base pipe, the middle of which is connected to the bottom end of the spray pipe, and quick-connect protrusions are provided at both ends of the connecting base pipe, which can be connected to quick-connect recesses.

[0013] Preferably, the connecting bottom pipe is a tee pipe or a four-way pipe, with the tee pipe being T-shaped and the four-way pipe being cross-shaped. The middle of the tee pipe or four-way pipe is connected to the bottom end of the spray pipe, and quick-connect protrusions are provided at the openings of the tee pipe or four-way pipe for connecting quick-connect concave heads.

[0014] Preferably, the spray head has several nozzles evenly arranged circumferentially, and the nozzles are divided into upper and lower layers, and the orientation of the nozzles can be adjusted.

[0015] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages:

[0016] This invention utilizes a series of spray components installed on the bridge deck, with the positions of these components freely arranged according to different bridge widths. The maximum distance between adjacent spray components is equal to the maximum spray diameter of the spray head, enabling spray curing of bridge deck pavements of varying widths, thus improving the efficiency and quality of curing. By extending and retracting the telescopic pipe within the spray pipe, the height of the spray head can be altered, and the nozzle orientation can be adjusted, improving water utilization and curing effectiveness while achieving versatility for curing bridge deck pavements of different widths. By setting the water pump as a time-delay pump, the spraying time can be controlled, requiring only the addition of water to the tank for curing. This allows for bridge deck pavement curing to be performed by a single person, reducing the investment of construction manpower and material resources, and saving costs. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5 As shown, this utility model provides a technical solution:

[0026] A spray curing device suitable for bridge deck pavements of different widths includes: several sets of spray components 1, which are evenly arranged on the bridge deck along its length. Adjacent spray components 1 are interconnected through connecting pipes 2, allowing water to flow between them; a water pump, which can be a commercially available water pump, with its inlet connected to a water tank pre-stored in water, and its outlet connected to the spray components 1; each spray component 1 includes a support frame 11, on which a spray pipe 12 is mounted, with a connector 13 at the bottom of the spray pipe 12 for connecting to the connecting pipe 2, and a telescopic pipe 14 coaxially slidably connected to the top of the spray pipe 12. The telescopic pipe 14 can extend and retract relative to the spray pipe 12, and the inner cavity of the spray pipe 12 is connected to the inner cavity of the telescopic pipe 14 to facilitate water flow. A spray head 15 is mounted on the top of the telescopic pipe 14 for spray curing.

[0027] In this embodiment, the support frame 11 includes a support ring 1101, which is sleeved on the outside of the spray pipe 12. Multiple support rods 1102, at least three, are evenly rotatably arranged on the outer side of the support ring 1101 to improve stability. One end of the support rod 1102 away from the support ring 1101 is rotatably connected to one end of the ground rod 1103 via a pivot. The other end of the ground rod 1103 is rotatably connected to one end of the support rod 1104 via a pivot. The other end of the support rod 1104 is rotatably connected to the support rod 1102 via a pivot. The support rod 1102, the ground rod 1103, and the support rod 1104 are connected in a triangular shape to improve the stability of the support rod 1102.

[0028] In this embodiment, the support rod 1102 is provided with an external thread on its outer side. The end of the support rod 1104 away from the ground rod 1103 is rotatably connected to the fixing ring 1105. The fixing ring 1105 is coaxially rotatably mounted on the sliding sleeve 1106. The sliding sleeve 1106 is threadedly connected to the support rod 1102. By rotating the sliding sleeve 1106, the position of the sliding sleeve 1106 on the support rod 1102 can be adjusted. This allows the support angle of the support rod 1104 to be adjusted so that the ground rod 1103 can always be close to the bridge surface when the support rod 1102 changes its support angle according to the site environment, thereby increasing the support area and improving the stability of the support.

[0029] In this embodiment, the bottom of the ground pole 1103 is in close contact with the bridge surface, and several anti-slip patterns 1107 are provided on the bottom surface of the ground pole 1103. The length direction of the anti-slip patterns 1107 is perpendicular to the length direction of the ground pole 1103 to increase the friction between the ground pole 1103 and the bridge surface, avoid displacement during maintenance and affect the quality of maintenance, and improve the safety of the device.

[0030] In this embodiment, the connecting pipe 2 is a flexible hose containing steel wire to prevent the connecting pipe 2 from being knotted or deformed by compression, which would affect the spraying effect. The outside of the connecting pipe 2 is covered with a wear-resistant layer to prevent the connecting pipe 2 from being damaged by frequent friction during use. Quick-connect recesses 21 are provided at both ends of the connecting pipe 2 for quick connection of the connector 13, thereby improving the efficiency of the device.

[0031] In this embodiment, the connector 13 includes a connecting bottom pipe 1301, the middle of which is connected to the bottom end of the spray pipe 12. Quick-connect protrusions 1302 are provided at both ends of the connecting bottom pipe 1301. The quick-connect protrusions 1302 can be connected to quick-connect recesses 21. Preferably, both the quick-connect protrusions 1302 and the quick-connect recesses 21 are common quick connectors on the market, which are economical.

[0032] In another embodiment, the connecting bottom pipe 1301 is set as a T-shaped pipe or a four-way pipe, and the T-shaped pipe is T-shaped and the four-way pipe is cross-shaped. The middle part of the T-shaped pipe or the four-way pipe is connected to the bottom end of the spray pipe 12. The opening of the T-shaped pipe or the four-way pipe is provided with a quick-connect protrusion 1302 for connecting the quick-connect concave head 21. When two rows of spray components 1 need to be arranged for spray maintenance, the T-shaped connecting bottom pipe 1301 can be selected. When three or more rows of spray components 1 need to be arranged, the spray components 1 around the perimeter can be made to use T-shaped pipes, the spray components 1 in the middle can be made to use four-way pipes, and then the adjacent spray components 1 are connected to each other. The outermost spray component 1 is connected to a water pump for water supply.

[0033] In this embodiment, a plurality of nozzles 1501 are evenly arranged circumferentially on the spray head 15. The nozzles 1501 are divided into upper and lower layers, and the orientation of the nozzles 1501 can be adjusted. The nozzles 1501 are commonly used universal adjustable nozzles 1501 on the market, which can freely adjust the angle of the nozzles 1501. The upper nozzles 1501 face the upper part of the device to spray the far end, and the lower nozzles 1501 face the lower part of the device to spray the near end, so that the spraying is more uniform and sufficient.

[0034] In another embodiment, a rubber ring is provided at one end of the telescopic pipe 14 located inside the spray pipe 12. The outer side of the rubber ring contacts the inner wall of the telescopic pipe 14 to seal the gap between the spray pipe 12 and the telescopic pipe 14 and prevent water leakage. An external thread is provided on the outer wall of the telescopic pipe 14, and an internal thread is provided on the inner side of the top opening of the spray pipe 12. The external thread of the telescopic pipe 14 and the internal thread of the top opening of the spray pipe 12 can be threadedly connected, so that the extension length of the telescopic pipe 14 can be adjusted by rotating the telescopic pipe 14, and temporary positioning can be achieved according to the self-locking effect of the thread, without affecting the flow of water.

[0035] Working principle: First, support frame 11 is properly positioned so that the bottom of ground pole 1103 is in close contact with the bridge deck. The support angle of support pole 1104 is controlled according to the angle between support pole 1102 and the ground. Then, support ring 1101 is fitted onto the outside of spray pipe 12. The height of spray head 15 is adjusted via telescopic pipe 14 according to the area to be sprayed. Then, the orientation of nozzles 1501 is adjusted so that the upper nozzle 1501 is tilted upwards and the lower nozzle 1501 is tilted downwards. The upper nozzle 1501 is used to spray the far end, and the lower nozzle 1501 is used to spray the near end. Then... Spraying components 1 are evenly arranged according to the width of the bridge deck. When only one row of spraying components 1 is needed, the spraying components 1 are placed in the middle of the bridge deck. The connecting bottom pipe 1301 is a straight pipe, which connects the front and rear adjacent spraying components 1 through the connecting pipe 2. Then, the connecting bottom pipes 1301 at both ends are connected to the water pump. When two or more rows of spraying components 1 are needed, the spraying components 1 are symmetrically arranged in the middle of the bridge deck. The connecting bottom pipe 1301 is a T-shaped pipe and a four-way pipe, which connects the front and rear and left and right adjacent spraying components 1 through the connecting pipe 2. One or more connecting bottom pipes 1301 are used to connect to the water pump. When the water pump is turned on, uniform spraying is achieved.
