Description

Technical Field

[0001] The utility model belongs to the technical field of precast staircase production and maintenance, and particularly relates to a maintenance device for precast staircases. Background Technique

[0002] A precast staircase is a staircase component produced in a factory. It completes processes such as steel bar binding, formwork installation, concrete pouring and maintenance in the factory, and then is transported to the construction site for installation. The precast staircase has the characteristics of high forming quality, stable finished product quality, green and low consumption, etc. Moreover, in the construction site, a mechanized hoisting method is adopted, with high construction efficiency, which helps to promote civilized construction. The maintenance device for precast staircases is a device used to ensure that the precast staircase reaches the required strength and stability during maintenance. The maintenance device usually includes a heating system, a humidifying system, a spraying system, etc., to ensure that the concrete obtains appropriate temperature and humidity conditions during the hardening process. Among them, the spraying system realizes the maintenance of the precast staircase by spraying water on the precast staircase to keep the concrete surface moist and promote the hardening of the concrete.

[0003] The existing maintenance device for precast staircases realizes the maintenance of the precast staircase by spraying water on the precast staircase. However, the position of the water spraying component for spraying water is fixed and cannot be moved to achieve comprehensive spraying of precast staircases of different sizes. The nozzles at fixed positions are difficult to adapt to precast staircases of different sizes and shapes, resulting in insufficient or excessive moisture in some parts, and the maintenance effect is discounted. For large or special-shaped precast components, fixed nozzles require a longer maintenance period or manual intervention to supplement water spraying, increasing time and resource consumption. At the same time, the non-flexible adjustable water spraying component limits its compatibility with diversified precast staircase products and affects production flexibility. Content of the Utility Model

[0004] In view of this, aiming at the deficiencies of the prior art, the utility model provides a maintenance device for precast staircases, in which the position of the water spraying pipe for maintaining the precast staircase can be moved and adjusted, and the position and angle can be adjusted according to the specific size and shape of the precast staircase to achieve all-round and uniform spraying, improve the maintenance quality, shorten the maintenance period, reduce unnecessary water resource waste, speed up the production rhythm, and at the same time enhance the flexibility of the production line and the diversity of products.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is as follows: A curing device for precast stairs, comprising a frame plate. A connecting plate is arranged at the upper end of the frame plate. Two cavity plates corresponding to each other in the front and rear positions are slidably arranged inside the connecting plate. Spray pipes are arranged in a plurality of spray holes evenly opened at the lower ends of the two cavity plates. Water inlet pipes are respectively arranged in two water inlet holes opened at the other ends of the two cavity plates. An adjusting drive mechanism for adjusting the front and rear movement of the spray pipes is arranged at the upper end inside the connecting plate. A recycling mechanism is arranged at the lower end of the frame plate. The adjusting drive mechanism includes a groove plate arranged at the upper end inside the connecting plate. Two rotating frames are slidably arranged inside the groove plate. Two connecting frames are rotatably arranged inside each of the two rotating frames. Two rotating seats are arranged at the upper ends of the two cavity plates. One ends of the four connecting frames away from the rotating frames are respectively rotatably connected to the inside of the adjacent rotating seats. A bidirectional lead screw is rotatably arranged at the upper end inside the connecting plate. The two rotating frames are respectively threadedly connected to the left and right corresponding ends of the bidirectional lead screw. An electric drive unit for driving the bidirectional lead screw to rotate is arranged on the left side of the connecting plate. The electric drive unit includes a motor arranged on the left side of the connecting plate. The output shaft of the motor is connected to the left end of the bidirectional lead screw through a coupling.

[0006] As a further improvement of the utility model, a control panel is arranged on the front side of the frame plate. The motor and the solenoid valve are both electrically connected to the control panel.

[0007] As a further improvement of the utility model, the recycling mechanism includes a collection box arranged at the lower end of the frame plate. A drain pipe is arranged in a drain hole opened on the front side of the collection box. A solenoid valve is connected in series in the middle of the drain pipe.

[0008] As a further improvement of the utility model, a plurality of rotating rollers are rotatably arranged inside the frame plate.

[0009] As a further improvement of the utility model, a support frame is welded and fixed at the lower end of the frame plate. A plurality of mounting holes are opened inside the support frame.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] Firstly, by placing the precast stairs to be cured on the rotating rollers inside the frame plate, then pushing the precast stairs to cooperate with the rotation of the rotating rollers to move them to the lower end of the spray pipes. Subsequently, the four water inlet pipes are externally connected to the external liquid delivery pipes. Water enters the inside of the cavity plates through the water inlet pipes and is sprayed onto the precast floor through a plurality of spray pipes, keeping the concrete surface moist and promoting the hardening of the concrete, thereby quickly realizing the curing of the precast stairs.

[0012] Second, by controlling the forward and reverse operation of the motor, the output shaft drives the bidirectional lead screw to rotate forward and backward, causing the rotating frame to approach or move away from each other under the restriction of the groove plate, driving the connecting frames inside its two sides to rotate and contract or expand. Furthermore, the water spray pipes at the lower ends of the two cavity plates are driven by the rotating seats to approach or move away from each other. The position of the water spray pipes for curing the precast stairs can be adjusted, and the position and angle can be adjusted according to the specific size and shape of the precast stairs, realizing all-round and uniform spraying, improving the curing quality, shortening the curing cycle, reducing unnecessary water resource waste, accelerating the production rhythm, and at the same time enhancing the flexibility of the production line and the diversity of products.

[0013] Third, the water sprayed by the water spray pipe will flow into the interior of the collection box through the gap between the rotating rollers due to the reason of gravity. Personnel can control and open the solenoid valve to make the collected water drain through the drain pipe, and it can be recycled to save water resources.

[0014] Fourth, the curing device can be stably supported by the support frame, and the installation holes inside it can assist personnel to fix the curing device, which can ensure that the curing device operates more stably and improve the curing quality of the precast stairs.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To better understand the present utility model, the content of the present utility model will be further clearly elaborated below in conjunction with embodiments. However, the protected content of the present utility model is not limited to the following embodiments. In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.

[0022] As Figure 1 、 2 、3, and 4 show, a curing device for precast stairs includes a frame plate 101. A connecting plate 106 is provided at the upper end of the frame plate 101. Two cavity plates 108 corresponding to the front and rear positions are slidably arranged inside the connecting plate 106. Spray pipes 109 are arranged in a plurality of spray holes evenly opened at the lower ends of the two cavity plates 108. Water inlet pipes 107 are respectively arranged in two water inlet holes opened at the other ends of the two cavity plates 108. An adjusting drive mechanism for adjusting the front and rear movement of the spray pipe 109 is arranged at the upper end inside the connecting plate 106. A recycling mechanism is arranged at the lower end of the frame plate 101. The recycling mechanism includes a collection box 301 arranged at the lower end of the frame plate 101. A drain pipe 302 is arranged in a drain hole opened on the front side of the collection box 301. An electromagnetic valve 303 is connected in series in the middle of the drain pipe 302.

[0023] As Figure 1 、 2 、4 show, the adjusting drive mechanism includes a groove plate 204 arranged at the upper end inside the connecting plate 106. Two rotating frames 203 are slidably arranged inside the groove plate 204. Two connecting frames 205 are rotatably arranged inside each of the two rotating frames 203. Two rotating seats 201 are arranged at the upper ends of the two cavity plates 108. One ends of the four connecting frames 205 away from the rotating frames 203 are respectively rotatably connected to the inside of the adjacent rotating seats 201. A bidirectional lead screw 206 is rotatably arranged at the upper end inside the connecting plate 106. The two rotating frames 203 are respectively threadedly connected to the left and right corresponding ends of the bidirectional lead screw 206. An electric drive unit for driving the rotation of the bidirectional lead screw 206 is arranged on the left side of the connecting plate 106. The electric drive unit includes a motor 202 arranged on the left side of the connecting plate 106. The output shaft of the motor 202 is connected to the left end of the bidirectional lead screw 206 through a coupling.

[0024] As Figure 1 、 2 As shown in, a plurality of rotating rollers 105 are rotatably arranged inside the frame plate 101.

Subsequently, connect the four water inlet pipes 107 to the external infusion pipes. Water enters the inside of the cavity plate 108 through the water inlet pipes 107 and is sprayed onto the precast floor slab through multiple water spray pipes 109 to keep the concrete surface moist and promote the hardening of the concrete, thus realizing the maintenance of the precast staircase.

[0027] It is also possible to control the forward and reverse rotation of the motor 202 through the control panel 104. The output shaft drives the bidirectional lead screw 206 to rotate forward and backward, so that the rotating frame 203 approaches or moves away from each other under the restriction of the groove plate 204, driving the connecting frames 205 inside its two sides to rotate and contract or expand. Furthermore, the water spray pipes 109 at the lower ends of the two cavity plates 108 are driven by the rotating seat 201 to approach or move away from each other, enabling more uniform water spraying maintenance for precast staircases of different sizes.

[0028] The water sprayed out by the water spray pipe 109 will flow into the inside of the collection box 301 through the gap between the rotating rollers 105 due to the reason of gravity.
