Description

Technical Field

[0001] The invention belongs to the technical field of concrete curing, and in particular relates to a concrete curing device. Background Art

[0002] Concrete curing is an inevitable and important part of infrastructure projects such as road projects and concrete construction projects. Generally speaking, concrete curing requires maintaining a certain humidity for a period of time to ensure that the poured concrete can harden normally and provide good strength characteristics.

[0003] At present, concrete pavement can be maintained by a mobile trolley, which is equipped with a water tank and a nozzle. During maintenance, the staff pushes the trolley to move on the pavement. During the movement of the trolley, the pavement is maintained by water sprayed from the nozzle. However, for concrete walls with a certain height, this walking trolley is not suitable, because for walls, water pipes are generally installed at the nozzles of the trolley manually, and then the concrete walls are sprayed with water by holding the water pipes. Therefore, the height angle of the nozzle is affected by the height of the staff and cannot adapt to walls with higher heights.

[0004] The prior art has the following deficiencies:

[0005] The current maintenance vehicles for spraying road surfaces cannot adapt to walls of higher heights. For the maintenance scenarios of concrete walls using such maintenance vehicles, water is generally sprayed on the concrete walls by hand-held water pipes. The height angle of the nozzle is affected by the height of the staff and is also time-consuming and labor-intensive. Summary of the invention

[0006] In view of this, the present invention provides a concrete curing device to solve the problems in the prior art that the maintenance vehicle for spraying the road surface has poor adaptability when performing spray curing on the concrete wall surface, and the manual operation is time-consuming and labor-intensive.

[0007] The technical solution adopted by the present invention is as follows:

[0008] A concrete curing device, comprising a support plate, a column is provided on the top of the support plate, a sliding seat is provided on the column and is slidably connected to the column, a bracket is provided at one end of the sliding seat, an end of the bracket away from the column is rotatably connected to a mounting frame through a rotating shaft, a pipe body is provided on the mounting frame, the pipe body and the support plate are parallel to each other, and a plurality of nozzles are connected to the end of the pipe body away from the column, and the plurality of nozzles are arranged at intervals along the axial direction of the pipe body;

[0009] The column is provided with a lifting device for driving the slide to move along the height direction of the column;

[0010] The bracket is provided with a rotating device for driving the rotating shaft to rotate;

[0011] A film laminating device is provided at the bottom of the supporting plate.

[0012] In this technical solution, it should be noted that the support plate is made of steel with a thickness of 20mm-50mm. A number of through holes are provided on the support plate to improve the water flow performance of the support plate. The rotating shaft and the mounting frame are fixedly connected, the rotating shaft and the bracket are rotatably connected, and the mounting frame is arranged horizontally; the lifting device can drive the slide to rise or fall to adjust the height of the nozzle, and the rotating device can drive the rotating shaft to rotate to adjust the angle of the nozzle. The coating device is arranged on one side of the bottom of the support plate, and the coating device is used to coat the road surface after the water spraying; when this solution is implemented, the staff connects the pipe body with the external water source. When the concrete road surface is to be sprayed and maintained, the slide is driven down to a lower position by the lifting device, and then the rotating shaft is driven to rotate by the rotating device so that the water outlet direction of the nozzle is inclined downward, and then Then the staff pushes the pallet to move, and at the same time the nozzle sprays maintenance water on the road surface to maintain the concrete road surface, and then covers the sprayed section with a thin film through the coating device; when the wall surface needs to be maintained, the rotating shaft is driven to rotate by the rotating device so that the water outlet of the nozzle is perpendicular to the wall surface, and then the sliding seat is driven to rise or fall by the lifting device, so that the nozzle can spray and maintain the positions at different heights of the wall surface; in summary, in the present invention, the height and angle of the nozzle can be adjusted by setting the lifting device, rotating shaft and rotating device, so that the device can not only spray and maintain the concrete road surface, but also spray and maintain the concrete wall surface with a certain height, which reduces the work intensity of the construction workers, and the road section where the water is sprayed can be coated by the coating device.

[0013] Preferably, the coating device includes a frame and a coating roller, the frame is fixed at the bottom of the support plate, the coating roller is rotatably connected to the frame through a driving shaft, a frame is provided on the outer side of the frame, the frame can slide along the height direction of the frame, a connecting rod is provided on one side of the frame, the connecting rod is arranged along the length direction of the support plate, and a pressing plate is connected to the bottom of the end of the connecting rod away from the frame through a spring; a cam is provided at one end of the driving shaft, the cam is located in the frame, and the cam can drive the frame to move up and down.

[0014] In this technical solution, it should be noted that there is a film on the coating roller. The device is mainly used to coat the road surface. When the device is in use, the staff pushes the pallet to move forward. During the movement of the pallet, the road surface is maintained by the maintenance liquid sprayed from the nozzle. After the pallet has moved a certain distance, the movement of the pallet is stopped, and one end of the film on the coating roller is placed on the road section sprayed with the maintenance liquid, and then the pallet is continued to be pushed forward. During the movement, the coating roller rotates to release the film on the coating roller. During the rotation of the coating roller, the drive shaft is driven to rotate, and the rotation of the drive shaft drives the cam to rotate. During the rotation of the cam, the frame will be driven to move back and forth up and down, thereby driving the pressing plate at one end of the connecting rod to move back and forth up and down to press the film on the coated road section, so that the film can better fit the road section. In addition, due to the provision of a spring, the pressing plate of the device can also adapt to uneven road sections without getting stuck.

A rack is provided on the inner wall of the rotating ring, and the racks are arranged at equal intervals along the circumference of the rotating ring. A gear meshing with the rack is rotatably connected to the slide, and the gear is driven by a second motor.

[0024] In this technical solution, it should be noted that in this solution, the rotating ring, gear and rack are set so that the nozzle can rotate around the column, that is, the nozzle can maintain concrete buildings in different directions, which increases the flexibility of the device; in the specific implementation of this solution, when it is necessary to spray and maintain concrete buildings in other directions, the second motor drives the gear to rotate, and the gear rotates to drive the rotating ring with the rack to rotate, thereby driving the nozzle to rotate in the horizontal direction, so that the water outlet of the nozzle faces the concrete building to be maintained, and finally, the concrete building is sprayed and maintained through the cooperation of the lifting device and the nozzle.
