Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction technology, and in particular to a civil engineering construction pouring device. Background Technology

[0002] Concrete is used in various civil engineering projects. The reason why concrete can gradually set and harden is mainly due to the hydration of cement, which requires appropriate temperature and humidity conditions. During the process of cement hardening, a large amount of heat of hydration is generated. Concrete is prone to cracking under uneven heat or high-temperature expansion conditions. Watering and cooling can effectively reduce or eliminate cracks. If concrete is not watered and cured in time, it may reduce the strength of concrete and cause cracks due to concrete shrinkage. Therefore, it is necessary to spray concrete with water regularly and carefully to prevent cracking.

[0003] In the prior art, patent CN223548979U discloses a civil engineering construction pouring device, including a vehicle platform, a water storage mechanism, an adjustment mechanism, and a spraying mechanism disposed on the vehicle platform. The water storage mechanism includes a water tank and a water pump. The water pump draws water from the water tank to the spraying mechanism connected thereto. The water storage mechanism is placed at the rear end of the vehicle platform. The adjustment mechanism is installed at the front end of the vehicle platform. The spraying mechanism is installed on the adjustment mechanism and communicates with the water storage mechanism. The adjustment mechanism includes a first rotating mechanism disposed on the front side of the front end of the vehicle platform and a second moving mechanism disposed on the back side of the front end of the vehicle platform. A filter mechanism is also disposed between the water storage mechanism and the spraying mechanism. The filter mechanism is installed in the middle of the vehicle platform.

[0004] The above solution can control the height and angle of the spray pipe through an automatic control adjustment mechanism, and filter the water in the storage tank to remove impurities through a filtration mechanism, which can effectively prevent impurities in the water from clogging the spray head. However, the above solution can only be used for spraying and irrigating concrete pavements, but it is not suitable for spraying some concrete walls. Utility Model Content

[0048] See Figures 1-10 A civil engineering construction irrigation device includes: a water storage mechanism, an angle adjustment mechanism, a lifting rod, and a spray pipe.

[0049] The lifting mast 3 includes a base 29, an outer mast 30, and an inner mast 31. The lower end of the outer mast 30 is fixed to the top of the base 29. The outer mast 30 is hollow inside with an opening at the top. One end of the inner mast 31 is slidably connected to the outer mast 30 through the opening. The height can be adjusted by sliding the inner mast 31 up and down inside the outer mast 30. A threaded hole is provided on the side wall of the outer mast, and a screw is threaded into the threaded hole to fix the inner mast 31 inside the outer mast 30. A dustproof sealing ring is provided at the top opening of the outer mast 30. The surfaces of the outer mast 30 and the inner mast 31 of the lifting mast 3 are anodized to improve corrosion resistance and extend the service life of the equipment. Alternatively, the lifting mast 3 can also be a hand-cranked lifting mast as in the prior art.

[0050] The angle adjustment mechanism includes: a connecting component, a rotating component, and a locking component.

[0051] The connecting assembly includes a first connecting rod 6 and a second connecting rod 7. The first connecting rod 6 is perpendicularly connected to the upper end of the inner rod 31. One end of the second connecting rod 7 is connected to one end of the first connecting rod 6 through a connecting plate 8. The width of the connecting plate 8 is less than the arc length corresponding to a quarter circle of the cross-sectional circumference of the tubes of the first connecting rod 6 and the second connecting rod 7. The opposing ends of the first connecting rod 6 and the second connecting rod 7 are respectively provided with a first cavity 9 and a second cavity 10. The two ends of the connecting plate 8 are respectively connected to the circumferential edges of the opposing ends of the first connecting rod 6 and the second connecting rod 7.

[0052] The rotating assembly includes a rotating rod 11, the diameter of which matches the inner diameter of the second cavity 10. One end of the rotating rod 11 is rotatably connected to the second cavity 10 and abuts against the bottom wall of the second cavity 10. The other end extends into the first cavity 9 of the first connecting rod 6, and the end face is provided with a first annular tooth 12. A through hole 13 communicating with the second cavity 10 is provided on the second connecting rod 7. A through hole 13 is also provided on the rotating rod 11. The through hole 13 of the second connecting rod 7 and the through hole 13 of the rotating rod 11 are aligned.

[0053] The locking assembly includes an elastic component, a pressure plate 14, and a pressing rod 16. The pressing rod 16 is slidably connected in two through holes 13. One end of the pressing rod 16 facing the first connecting rod 6 is connected to the pressure plate 14, and the other end of the pressing rod 16 extends to the outside of the second connecting rod 7. A second sliding groove 22 is provided on the inner wall of the through hole 13 of the second connecting rod 7. A second slider 23 matching the second sliding groove 22 is connected to the side wall of the pressing rod 16. The second slider 23 is slidably connected to the second sliding groove 22 to limit the pressing rod 16, so that the pressing rod 16 can only move towards or away from the first connecting rod 6. The pressure plate 14 is slidably connected in the first cavity 9, and a second annular tooth 15 is provided on the end face of the pressure plate 14 facing the second connecting rod 7.

[0054] An elastic component is connected within the first cavity 9 of the first connecting rod 6. The elastic component includes a first tube 17 and a second tube 18. The first tube 17 is connected to the bottom wall of the first cavity 9, and the second tube 18 is connected to the end face of the pressure plate 14 away from the second annular tooth 15. The outer diameter of the second tube 18 matches the inner diameter of the first tube 17. The second tube 18 is slidably connected within the first tube 17, and a first groove 20 is provided on the inner wall of the first tube 17. A first slider 21 matching the first groove 20 is connected to the outer wall of the second tube 18. The first slider 21 is slidably connected within the first groove 20, so that the first tube 17 and the second tube 18 form an axially sliding nested connection structure. A spring 19 is connected between the bottom wall of the first tube 17 and the bottom wall of the second tube 18. When the spring 19 is in a fully extended state, the first tube 17 remains at least partially located within the inner cavity of the second tube 18 and will not detach.

[0055] Alternatively, an annular groove or a central positioning hole can be machined on the bottom wall of the first tube 17 and the bottom wall of the second tube 18 respectively. The two ends of the spring 19 are respectively embedded in these two annular grooves or central positioning holes to achieve axial alignment and limiting. The depth of the annular groove is slightly smaller than the spring wire diameter, which can both limit and facilitate assembly.

[0056] It should be noted that the first annular tooth 12 and the second annular tooth 15 are helical end face teeth, the spring 19 is made of 304 stainless steel, and the locking force of the spring 19 must be greater than the maximum reverse torque generated by gravity, wind force or equipment movement inertia under the maximum length and full water load of the spray pipe 4, with a safety factor of 1.5~2.0. In use, the spring 19 pushes the pressure plate 14 to move outward, so that the second annular tooth 15 of the pressure plate 14 meshes with the first annular tooth 12 of the rotating rod 11, restricting the rotation of the rotating rod 11. When the pressing rod 16 is pushed, the pressing rod 16 will push the pressure plate 14. At this time, the spring 19 is compressed, the second annular tooth 15 separates from the first annular tooth 12, and the rotating rod 11 can rotate.

[0057] Secondly, a threaded hole is opened on the second connecting rod 7, and a manual locking screw is added. The screw is screwed in radially, and its end can abut against the side wall of the rotating rod 11. When the length of the connected spray pipe 4 reaches a certain length, in order to prevent shaking, after unlocking by pressing the rod 16 and adjusting to the required angle, in addition to releasing the pressing rod 16 and relying on the spring 19 to achieve gear engagement and locking, this manual locking screw can be tightened to form a friction pair to assist in locking, effectively preventing angle deviation when the equipment moves or is impacted by external forces.

[0058] In addition, the sliding joint between the first tube body 17 and the second tube body 18 should be equipped with a grease injection port or pre-filled with long-lasting grease to reduce wear and ensure smooth operation.

[0059] It should also be noted that a dustproof sealing ring (such as an O-ring) is provided at the connection between the rotating rod 11 and the first cavity 9 and the second cavity 10 to prevent construction dust and cement slurry from intruding and causing wear, jamming or failure.

[0060] Furthermore, a T-shaped mounting plate 24 is connected to the side wall of the rotating rod 11. The T-shaped mounting plate 24 includes a first plate and a second plate that are perpendicularly connected to each other. One end of the first plate is perpendicularly connected to the side wall of the rotating rod 11, and a triangular rib is added at the connection. The other end of the first plate is connected to the middle of the second plate, thereby forming a T-shaped structure as a whole. The second plate is perpendicular to the rotating rod 11.

[0061] The second plate has several sets of connection holes along its length. The spray pipe 4 is arranged parallel to the surface of the second plate away from the first plate. Several U-shaped pipe clamps are straddling the spray pipe 4, and the two free ends of each U-shaped pipe clamp pass through the corresponding set of connection holes and are fixed to the second plate by fasteners, thereby clamping and limiting the spray pipe 4 on the second plate.

[0062] Furthermore, the sprinkler pipe 4 includes: a main pipe 25, several secondary pipes 26, and several pipe plugs 27. The main pipe 25 serves as the base section, with internal threads at both ends. The secondary pipes 26 serve as intermediate extension sections, with external threads at one end and internal threads at the other. The ends of the secondary pipes 26 can be threaded to the ends of the main pipe 25. The external threaded end of one secondary pipe 26 is threaded to the internal threaded end of another secondary pipe 26. During installation, the main pipe 25 is connected to the T-shaped mounting plate 24. Then, according to the required length on site, one or more secondary pipes 26 are sequentially screwed onto one or both ends of the main pipe 25. Finally, externally threaded pipe plugs are screwed into the two free ends of the overall assembly to achieve a seal. The main pipe 25 has a water inlet. The water pump 2 is connected to the water tank 1 via a water pipe. The water pump 2 is connected to the water inlet of the main pipe 25 via a flexible hose. Several sprinkler heads 5 are installed on both the main pipe 25 and the secondary pipes 26.

[0063] The nozzle 5 is an adjustable fan-shaped nozzle with a spray angle adjustable from 30° to 120°, a spray coverage width of 0.5m to 2m, and a spray flow rate of 0.5L / min to 2L / min, which can be precisely adjusted according to the concrete curing requirements. The main pipe 25 and the secondary pipe 26 of the spray pipe 4 are equipped with anti-clogging filters, which can effectively filter impurities in the water and prevent nozzle clogging, so as to facilitate uniform spraying.

[0064] In addition, the T-shaped mounting plate 24 and the spray pipe 4 can be made of aluminum alloy, which reduces weight and helps to lower the overall center of gravity of the equipment, making the mobile vehicle more stable when pushed and parked and less prone to tipping over.

[0065] Furthermore, it also includes: a mobile carrier 28, which can be a handcart, including a support plate 32. The bottom of the support plate 32 is connected to four casters 33, and push-pull handles 34 are connected to the side wall of the support plate 32. The base 29 of the lifting rod 3 can be fixed to the top of the support plate 32 with four M12 bolts to ensure that it will not loosen during movement. The water tank 1 and the water pump 2 can also be placed on the support plate 32. For the water tank 1, a groove or edge with a strap buckle can be provided; for the water pump 2, a bolt mounting position with a shock-absorbing pad can be provided. On one side of the support plate 32, a manually retractable hose reel is integrated to store the hose connecting the water pump and the sprinkler pipe, avoiding messy, tangled and worn pipes.

[0066] In addition, a waterproof battery compartment with a lock is designed on the support plate 32, and a cable storage hook is planned to provide power to the water pump; a fixing device is set on the support plate 32, and of course the mobile carrier 28 can also be an electric flatbed truck.

[0067] The workflow of this utility model is as follows:

[0068] Scenario 1: For example Figure 7 As shown, at this stage, the concrete has initially hardened but still needs to be moisturized and cured. In order to prevent damage to the concrete pavement, the mobile vehicle 28 moves along the hardened area or the pavement without concrete. The staff can adjust the spray pipe 4 to be parallel to the ground through the angle adjustment mechanism, or adjust the height of the spray pipe 4 according to the lifting rod. Depending on the required spray width, several auxiliary pipes 26 are connected to one end of the main pipe 25 of the spray pipe 4 in sequence. Then, the other end of the main pipe 25 and the other end of the last auxiliary pipe 26 are connected to the pipe plug 27. Then, the water pump 2 is turned on. During the spraying process, the staff can move the mobile vehicle 28.

[0069] Scenario 2: For example Figure 8As shown, the concrete has hardened to a certain strength, at which point the mobile vehicle can move. The mobile vehicle can be placed in the middle position. The staff can adjust the spray pipe 4 to be parallel to the ground through the angle adjustment mechanism, or adjust the height of the spray pipe 4 according to the lifting rod. Depending on the required spray width, several auxiliary pipes 26 are connected to both ends of the main pipe 25 of the spray pipe 4 in sequence. Then, the other ends of the two outermost auxiliary pipes 26 are connected to pipe plugs 27. Then, the water pump 2 is turned on. During the spraying process, the staff can move the mobile vehicle 28.

[0070] Scenario 3: For example Figure 9 As shown, this is used to spray the concrete wall. The mobile vehicle can be placed on the road next to the concrete wall. The operator can adjust the spray pipe 4 to be parallel to the concrete wall through the angle adjustment mechanism. According to the height of the concrete wall, several secondary pipes 26 are connected to both ends of the main pipe 25 of the spray pipe 4 in sequence. Then, the other ends of the two outermost secondary pipes 26 are connected to the pipe plugs 27. Then, the water pump 2 is turned on. During the spraying process, the operator can move the mobile vehicle 28.
