Description

Technical Field

[0001] The utility model relates to the technical field of concrete curing, in particular to a portable curing device for maintaining large-area concrete. Background Art

[0002] After pouring concrete, if the climate is hot and the air is dry, if it is not maintained in time, the water in the concrete will evaporate too quickly, resulting in dehydration. The cement particles that have formed a gel cannot be fully hydrated and cannot be converted into stable crystals. The lack of sufficient bonding strength will cause flaking or powdery shedding on the concrete surface. In addition, when the concrete does not yet have sufficient strength, the premature evaporation of water will also cause large shrinkage deformation and shrinkage cracks. Therefore, maintenance in the initial stage after concrete pouring is very important.

[0003] After searching, for example, the utility model patent with Chinese patent publication number CN215368824U discloses a portable concrete spraying and curing device, including a bracket and a spraying assembly. A driving assembly is provided on the top of the bracket, and the driving assembly includes a driving box. A rotating shaft is rotatably installed in the driving box, and a first bevel gear is installed on the rotating shaft. The top end of the rotating shaft passes through the top wall of the driving box and is connected to a turntable. A motor is installed in the driving box, and the output end of the motor is connected to a second bevel gear, which meshes with the first bevel gear. The bottom end of the spraying assembly is detachably connected to the turntable through a clamping assembly. A water inlet pipe is provided at the top of the spraying assembly, and a buffer groove is opened downward at the top. The buffer groove is movably connected to one end of the water inlet pipe. The bottom end of the buffer groove is connected to a water guide pipe, and the two ends of the water guide pipe are respectively connected to a spray head through the side walls of the spraying assembly. The utility model rotates the spraying assembly by the driving assembly, so that the spraying and curing of the concrete is more uniform, which improves the utilization rate of water resources and the spraying efficiency.

[0004] The portable concrete spray curing device drives the spray assembly to move in a circular motion, thereby performing rotary spraying. However, the spray head of the device is fixed in position and the spraying width cannot be adjusted. For large-area concrete curing, the spraying efficiency is low. Therefore, a portable curing device for large-area concrete maintenance is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 In this embodiment, a portable curing device for large-area concrete maintenance includes a base 1, a fixed platform 2 is provided on the top of the base 1, a turntable 7 is rotatably installed inside the fixed platform 2, a water collecting box 3 is provided on the top of the turntable 7, and a water spray pipe 4 is provided on the right side of the water collecting box 3.

[0023] The water spray pipe 4 includes an inner pipe 41 , which is fixedly mounted on the right side of the water collecting box 3 , and an outer pipe 42 is movably mounted on the outer surface of the inner pipe 41 , with locking components 43 provided on both the front and rear sides of the outer pipe 42 .

[0024] When adjusting the length of the water spray pipe 4, the outer tube 42 is pulled left or right, and the outer tube 42 drives the sealing retaining ring to slide left and right on the surface of the inner tube 41. After the outer tube 42 is pulled to the appropriate length, some water outlet holes 51 of the inner tube 41 and the outer tube 42 overlap, and water is sprayed from the overlapping water outlet holes 51 for concrete maintenance. The sealing retaining ring plays a sealing role to prevent water from flowing out from the gap where the inner tube 41 and the outer tube 42 are connected.

[0025] The two locking assemblies 43 each include an installation box 501, and the installation boxes 501 are fixedly installed on the front and rear sides of the outer tube 42. Locking rods 502 are installed through the interiors of the two installation boxes 501, and limiting plates 503 are fixedly installed on the outer surfaces of the two locking rods 502. Springs 504 are sleeved on the outer surfaces of the two locking rods 502.

[0026] The working principle of the locking assembly 43 is as follows: the locking rod 502 is pulled outward, and the locking rod 502 drives the limiting plate 503 to move in the direction of the spring 504. The spring 504 contracts, and the locking rod 502 withdraws from one of the locking holes 52, releasing the fixation on the outer tube 42. After the outer tube 42 is adjusted to a suitable position, the locking rod 502 is released, and the spring 504 expands so that the locking rod 502 is inserted into the corresponding locking hole 52, completing the locking of the outer tube 42 and fixing the water spray pipe 4 to the required length.

[0027] The angle adjustment mechanism 6 includes a threaded rod 601 , a threaded block 602 , a movable rod 603 and a support frame 604 .

[0028] When adjusting the spraying angle, first, the threaded rod 601 rotates to drive the threaded block 602 to move to the right, the threaded block 602 drives the movable rod 603 to rotate, and the movable rod 603 drives the fixed platform 2 to rotate on the support frame 604, thereby adjusting the water spray pipe 4 to a suitable spraying angle.

[0029] It should be added that a rotating device is provided at the bottom of the turntable 7, which includes a motor, bevel gear 1, bevel gear 2 and a vertical rod. Under their joint action, the turntable 7 can be rotated, so that the water spray pipe 4 can be rotated for uniform spraying.

[0030] A handle is provided on the top of the base 1. When carrying, the water spray pipe 4 is retracted to the shortest length and the device can be moved to other locations through the handle. If the spraying location is higher, the device can be placed on a bracket.

[0031] The water delivery component includes a water pump, a water diversion pipe and a water delivery pipe. One end of the water diversion pipe is connected to the external water source through a rotary joint, so that the water delivery component can rotate smoothly. The water source enters the water collecting box 3 through the water delivery component and is sprayed out through the water spray pipe 4.

[0032] In summary, the portable maintenance device for large-area concrete maintenance, by forming a water spray pipe 4 consisting of an inner pipe 41 and an outer pipe 42 that can move left and right on the outer surface of the inner pipe 41, can change the length of the water spray pipe 4, thereby flexibly adjusting the water spray range according to the maintenance area of ​​the concrete. This not only prevents the waste of water resources when spraying in a small area, but also enables rapid completion even when used for large-area concrete maintenance.

[0033] Furthermore, by providing the angle adjustment mechanism 6, the spraying angle of the water spray pipe 4 can be changed, thereby adjusting the direction and distribution of the water flow to adapt to concrete surfaces of different areas and shapes.
