Description

Technical Field

[0001] The present application relates to the technical field of prefabricated beam maintenance, and in particular to a prefabricated beam spray maintenance device. Background Art

[0002] With the increasing number of construction projects such as highways, railways, and viaducts, the use of precast beams is also increasing. In order to save and reduce construction costs, precast beams are best precast near the construction site. Since the quality of precast beams plays a decisive role in the structure of the facility, and concrete strength is an important indicator for evaluating the quality of precast beams. Concrete strength is not only related to raw materials and construction technology, but also has a direct relationship with the maintenance of concrete. After the precast beam is poured, if the concrete is in a dry environment, the water in the concrete evaporates too quickly, the concrete is dehydrated, and the surface will peel off in a flaky or powdery manner; at the same time, when the concrete does not have sufficient strength, the premature evaporation of water will also produce large shrinkage deformation and shrinkage cracks; the hydration inside the concrete cannot be fully carried out due to water loss, causing the crystal structure to relax and the strength to decrease. Therefore, in the precast beam yard temporarily set up near the construction site, after the precast beam concrete is poured, the precast beams are artificially sprinkled with water as soon as possible for moisturizing and maintenance.

[0003] However, the traditional manual watering and moisturizing maintenance will lead to inadequate local curing of precast beams, resulting in low strength and inability to be tensioned in time; uneven curing will leave traces of curing, causing secondary pollution to the appearance quality of the concrete; the maintenance nozzles cannot fully cover the entire area, resulting in a waste of water resources, etc. In addition, manual watering maintenance is inefficient, cannot provide 24-hour all-weather coverage, and has high labor costs.

[0029] See also Figure 1 and Figure 2 The precast beam spray curing equipment includes a walking system and a spray curing system. The walking system is used to drive the spray curing system to move along the bridge direction to fully spray the precast beam. The walking system includes a wraparound gantry 11, a walking trolley 12 and a walking track 13. The wraparound gantry 11 is arranged circumferentially around the cross section of the precast beam. The walking track 13 is arranged on the beam surface of the precast beam and extends along the bridge direction. The walking trolley 12 is arranged on the walking track 13. The wraparound gantry 11 is arranged on the walking trolley 12. The walking trolley 12 moves along the length direction of the walking track 13 to drive the wraparound gantry 11 to move along the bridge direction. The spray maintenance system includes a nozzle 21, a water supply pump 22 and a water purification circulation system. The nozzle 21 is arranged on the surround-type gantry 11. The nozzle 21 is connected to the water purification circulation system. The water supply pump 22 is used to enable the water purification circulation system to supply water to the nozzle 21, so that the nozzle 21 sprays water toward the prefabricated beam to achieve the purpose of maintenance.

[0030] Specifically, the surround-type portal frame 11 includes a top beam 111 and two side beams 112 connected to form a U-shaped structure. The two side beams 112 are respectively located at both ends of the top beam 111 in the length direction. The top beam 111 is located above the beam surface of the precast beam, and the length of the top beam 111 is greater than the width of the precast beam. The two side beams 112 are respectively located on both sides of the precast beam along the longitudinal direction of the bridge, so as to be arranged around the circumference of the precast beam.

[0031] Furthermore, the two side beams 112 are detachably connected to the top beam 111, and both ends of the top beam 111 are provided with connection ports, the side beams 112 are inserted into the connection ports, and the side beams 112 are provided with connection holes, and threaded fasteners are provided in the connection holes to connect with the top beam 111 to achieve the fixation between the side beams 112 and the top beam 111. At the same time, a plurality of connection holes are provided along the length direction of the side beams 112, so that the length of the side beams 112 radiating to the prefabricated beams can be adjusted to adapt to the spray curing operation of prefabricated beams of different specifications.

[0032] Two of the travel rails 13 are arranged side by side along the bridge, and the travel trolley 12 includes a frame and a travel structure. The travel structure is located at the bottom of the frame and cooperates with the two travel rails 13.

When the driving motor drives the travel wheels to rotate, the auxiliary travel wheels also rotate under the transmission action of the conveyor belt.

[0033] In this embodiment, two groups of the walking wheels and auxiliary walking wheels are provided corresponding to the two walking tracks 13, and the two groups of walking wheels can be coaxially connected through a transmission shaft, and the driving motor is connected to the transmission shaft to directly drive the transmission shaft to rotate, thereby realizing the synchronous rotation of the two groups of walking wheels and improving the moving efficiency of the walking trolley 12. In addition, in this embodiment, two groups of surround-type portal frames 11 are arranged side by side along the bridge direction.

The water collecting tank 231 is provided with a water inlet 2311, and the filtering device 232 is arranged at the water inlet 2311. The drainage trough 233 is connected to the water inlet 2311, that is, the curing water after spraying the beam body concrete for curing can flow back to the water collecting tank 231 through the drainage trough 233 for recycling.

Specifically, workers can use the client such as APP, computer program, etc. to send control instructions such as starting and stopping the drive motor, adjusting the speed of the drive motor, starting and stopping the water supply pump 22, and adjusting the pumping pressure of the water supply pump 22 to the wireless signal transceiver through the terminal device, so that the walking speed of the surround gantry 11 along the precast beam and the spraying flow of the nozzle 21 can be adjusted according to the actual ambient temperature, effectively avoiding the disadvantages of concentrated spraying of the concrete surface for maintenance, reducing the problem of uneven wetting of traditional moisturizing maintenance, and solving the adverse effects of maintenance water marks caused by improper maintenance, ensuring the early concrete strength growth of the beam body after demolding.

[0037] In summary, the precast beam spraying and curing equipment of the present application adopts a surround-type gantry 11 and a walking trolley 12 to spray and curing the beam surface and both sides of the precast beam. The spraying coverage is wide, reducing curing dead angles, and the nozzles 21 are arranged under the surround-type gantry 11, so that the distances from each nozzle 21 to the precast beam are the same, and the spraying and curing effect is highly consistent, which can effectively ensure the curing quality of all parts of the beam body, with better curing effect and higher efficiency, and can improve the concrete strength of the beam body. In addition, the precast beam spraying and curing equipment of the present application can be remotely controlled through a mobile phone APP or other client, without the need for manual pouring by workers, reducing labor input and improving construction efficiency. Moreover, the precast beam spraying and curing equipment of the present application can be used in a turnover manner, and the curing water sprayed can be recycled to reduce construction costs and water costs.
