[0002] Concrete is a commonly used building material. Construction cannot be done without the help of concrete. During the concrete pouring process, if the concrete dries too quickly and the water is lost quickly, it is easy to crack and affect the strength of the concrete. Therefore, maintenance equipment is needed to maintain the concrete.

[0003] The Chinese utility model patent with publication number CN220328999U discloses a concrete maintenance device for construction, specifically providing a concrete maintenance device for construction that is easy to store and helps improve watering efficiency, and is more practical. After searching, the above-mentioned comparative documents only maintain concrete by replenishing water. However, in the actual construction process, in order to reduce the rate of water loss, a film is also applied to the surface of the concrete. However, the maintenance devices currently on the market do not have the function of auxiliary film coating while replenishing water, and the problem of insufficient uniformity of water replenishment needs to be improved. Therefore, it is urgent to improve the existing concrete maintenance device and provide a concrete maintenance device for construction with an auxiliary film coating function. Utility Model Content

The limit rod 71 is welded and fixed in a limit groove opened inside the right end of the vehicle body 1, and movable blocks 72 are slidably sleeved on the outer sides of the front and rear ends of the limit rod 71. The left ends of the two movable blocks 72 are fixed with limit blocks 73, the right ends of the two movable blocks 72 are fixed with connecting columns 74, and a water distribution pipe 75 is fixed between the right ends of the two movable blocks 72. A plurality of nozzles 76 are equidistantly installed at the bottom of the water distribution pipe 75 along its length.

[0030] In this embodiment, the arrangement of the limiting block 73 and the limiting rod 71 can effectively improve the stability of the movable block 72 and the water distribution pipe 75 during the sliding process.

[0031] As a preferred embodiment, based on the above structure, further, the limit block 73 is engaged and slidably located in the groove opened on the left side wall of the limit groove, and the end of the hose 6 away from the water pump 4 is fixedly connected to the water inlet end of the water distribution pipe 75.

[0032] In this embodiment, the water distribution pipe 75 and the plurality of nozzles 76 disposed on the outer wall of the bottom thereof facilitate spraying and replenishing water to the concrete, thereby curing the concrete.

[0033] As a preferred embodiment, on the basis of the above structure, further, the rear wheel assembly 8 includes a transverse shaft 81, a rear wheel 82, a first gear 83 and a guide groove 84, the bearing of the transverse shaft 81 is installed inside the right end of the vehicle body 1, one end of the transverse shaft 81 is fixedly connected to the rear wheel 82, the first gear 83 is fixedly sleeved on the outer side of the middle part of the transverse shaft 81, and the outer wall of one end of the transverse shaft 81 away from the rear wheel 82 is symmetrically provided with guide grooves 84, and the two guide grooves 84 are connected to each other.

The outer sides of both ends of the unwinding rod 91 are fixedly sleeved with second gears 92, and a plastic film 93 is wound and installed on the outer side of the middle part of the unwinding rod 91. The two second gears 92 are respectively meshed and connected with the two first gears 83.

[0038] In this embodiment, the plastic film 93 can be automatically released by rotating the unwinding rod 91. The plastic film 93 attached to the concrete surface can effectively reduce the speed of water loss and improve the curing effect on the concrete.

[0039] The working principle of the utility model is as follows:

[0040] When in use, first fill the water tank 3 with clean water, then push the vehicle body 1 to the designated position.

During the movement of the vehicle body 1, the steering wheel 2 facilitates the device to turn, and the rear wheel 82 can drive the horizontal axis 81 to rotate, and the guide groove 84 provided on the outer surface of the horizontal axis 81 can be used to squeeze the connecting column 74, and the connecting column 74 drives the movable block 72 and the water distribution pipe 75 to move back and forth along the limit rod 71 in a reciprocating manner. By using multiple nozzles 76 that move back and forth in a small manner, the concrete can be sprayed and replenished with water more fully and evenly, and the maintenance effect is better.

[0041] At the same time, when the horizontal shaft 81 drives the first gear 83 fixed on the outside thereof to rotate, it can also drive the unwinding rod 91 to rotate through the second gear 92, so that the plastic film 93 can be slowly and orderly released while the vehicle body 1 moves to replenish water, so that the plastic film 93 adheres to the concrete floor, so that the maintenance device has the function of auxiliary film covering. Through the covering of the plastic film 93, the speed of water loss can be effectively reduced, and the maintenance effect on the concrete can be improved;
