Description

Technical Field

[0001] The utility model relates to the technical field of concrete curing, and more specifically to a concrete curing device for highway engineering construction. Background Art

[0002] Concrete maintenance is an indispensable part of concrete construction. Its main purpose is to ensure the normal hardening process of concrete, promote the development of its strength, and at the same time improve the durability of concrete and reduce the occurrence of cracks. The growth of concrete strength mainly depends on the hydration of cement. When cement is mixed with water, a chemical reaction will occur to produce hydration products. These products are the basis for concrete hardening and forming strength. Concrete will shrink during the hardening process. If the shrinkage is uneven or subject to external constraints, cracks are likely to occur. Proper maintenance can prevent the rapid drying of the concrete surface and reduce cracks caused by uneven shrinkage. By keeping the concrete surface moist, the rate of water evaporation can be slowed down, making the concrete more uniform during the hardening process.

[0003] At present, in the process of highway construction, in order to improve the structural strength of the concrete pavement after solidification, it is usually necessary to lay a film on its surface for maintenance within 8-12 hours after the concrete is poured. During the laying of the film, the staff usually carries the film roll by a trolley, and fixes one end of the film roll on one end of the concrete pavement that needs to be maintained, and pushes the trolley to unroll the film and lay it on the concrete pavement. However, in the existing laying work, since the film roll is prone to wrinkles during the unrolling process, the film roll cannot usually be evenly laid on the concrete pavement, which leads to waste of the film roll, and the uneven distribution of the film roll will also affect the hydration reaction of cement and water, thereby affecting the maintenance quality of the concrete pavement. In view of this, we propose a concrete curing device for highway construction. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a concrete curing device for highway engineering construction to solve the technical problems that the current film coils are prone to wrinkles during the unwinding process, and the film coils are usually unable to be evenly laid on the concrete pavement, which leads to waste of the film coils. The uneven distribution of the film coils will also affect the hydration reaction of cement and water, thereby affecting the maintenance quality of the concrete pavement.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a concrete curing device for highway engineering construction, comprising a vehicle body component with a material roll component detachably arranged therein;

[0006] The vehicle body assembly comprises a frame with a load-bearing frame detachably mounted on the top, one end of the frame is an open structure, and a tensioning assembly is arranged at the opening position of the frame;

[0007] The material roll assembly comprises an unwinding assembly which is symmetrically arranged and rotatably connected to the carrying frame, and a film roll is wound between the outer edge surfaces of the unwinding assembly;

[0008] The tensioning assembly includes a rotating mechanism that is symmetrically arranged and rotatably connected to the supporting frame, a connecting plate is detachably installed between the rotating mechanisms, a U-shaped plate is symmetrically constructed inside the connecting plate, a paving component is rotatably installed between the U-shaped plates, and a crank is constructed on one of the rotating mechanisms.

[0009] The utility model designs a rotating mechanism, a U-shaped plate, a connecting plate and a paving component. During the laying process of the film on the concrete surface, the film roll abuts against the surface of the paving component, and the film roll is tensioned by the paving component, thereby reducing wrinkles on the surface of the film roll, which is beneficial to ensure that it is evenly laid on the concrete pavement. By toggling the crank, it can drive the paving component to deflect, thereby adjusting the tensioning force of the film roll.

[0010] Preferably, the paving component includes a tensioning roller whose two ends are rotatably connected to the U-shaped plate, and the outer edge surface of the tensioning roller is provided with paving components distributed in a mirror-symmetrical manner. The paving component includes a staggered paving structure, and the paving structure includes spiral rubber strips fixedly arranged in a ring array on the outer surface of the tensioning roller.

[0011] Preferably, the rotating mechanism includes a rotating seat rotatably installed in the supporting frame, a rotating shaft is rotatably arranged inside the rotating seat, a U-shaped clamp rod is constructed at one end of the rotating shaft, and the U-shaped clamp rod can be removably clamped on the connecting plate, and a threaded hole is opened on the outer edge surface of the rotating seat, and the inner thread of the threaded hole is cooperated with to install a limiting bolt.

[0012] Preferably, the unwinding assembly comprises a turntable with a rotating shaft fixedly arranged inside, one end of the rotating shaft is rotatably connected to the supporting frame, and connecting components are arranged in a ring array on the outer edge surface of the rotating shaft.

[0013] Preferably, an end of the connecting component away from the rotating shaft is connected to an arc-shaped support plate, and an end of the arc-shaped support plate facing the turntable is detachably mounted with a triangular retaining frame, and the film roll is wound on the arc-shaped support plate.

[0014] Preferably, connecting arms are detachably mounted on both side ends of the frame, a push frame is detachably connected to one end of the connecting arms away from the frame, and universal wheels are detachably mounted on the four bottom corners of the frame.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model designs a rotating mechanism, a U-shaped plate, a connecting plate and a paving component. During the laying process of the film on the concrete surface, the film roll abuts against the surface of the paving component, and the film roll is tensioned by the paving component, thereby reducing wrinkles on the surface of the film roll, which is beneficial to ensuring that it is evenly laid on the concrete pavement. By turning the crank, it can drive the paving component to deflect, thereby adjusting the tensioning force of the film roll, solving the problem that the film roll is prone to wrinkles during the unwinding process. The film roll usually cannot be evenly laid on the concrete pavement, which leads to waste of the film roll. In addition, the uneven distribution of the film roll will also affect the hydration reaction of cement and water, thereby affecting the maintenance quality of the concrete pavement.

[0017] 2. The utility model also designs a paving component on the surface of the tensioning roller, and designs the spiral rubber strip as a spiral structure. During the rotation of the tensioning roller, the spiral structure of the spiral rubber strip is conducive to tensioning the film roll while applying tension from the middle to both sides, thereby improving the paving effect, which is conducive to further reducing wrinkles on the surface of the film roll and further ensuring its uniform paving on the concrete pavement.
