The water pipe is arranged in the plurality of first connecting pipes 210 and the plurality of second connecting pipes 220.

[0047] The first connecting tube 210 includes a first connecting rod 211 and a first telescopic rod 212, the first telescopic rod 212 is located at the lower side of the first connecting rod 211, and the lower end of the first connecting rod 211 is rotatably connected to the upper end of the first telescopic rod 212. The second connecting tube 220 includes a second connecting rod 221 and a second telescopic rod 222, the second telescopic rod 222 is located at the lower side of the second connecting rod 221, and the lower end of the second connecting rod 221 is rotatably connected to the upper end of the second telescopic rod 222. The first telescopic rod 212 and the second telescopic rod 222 are both telescopic, and a plurality of nozzles 223 are provided on the peripheral wall of each first telescopic rod 212 and each second telescopic rod 222.

[0048] Each spray assembly has a first state and a second state. The first state of the spray assembly is that the first connecting rod 211 and the first telescopic rod 212 are arranged in parallel, and the second connecting rod 221 and the second telescopic rod 222 are arranged in parallel.

The length of the first telescopic rod 212 and the second telescopic rod 222 is longer than the width of the tread and riser of the concrete staircase.

[0049] In the initial state, the spray assembly is in the first state. The concrete staircase is placed flat inside the housing 100 and is located below the spray mechanism. The first connecting tube 210 and the second connecting tube 220 are rotated so that the height of the first connecting tube 210 and the second connecting tube 220 in the vertical direction becomes narrower, the width in the second direction increases, and the angle between the upper and lower ends of the first connecting tube 210 and the second connecting tube 220 increases. The first connecting tube 210 and the second connecting tube 220 are no longer rotated until the lower end of each second connecting tube 220 and the intersection of two adjacent steps are in the same straight line.

[0050] Then, the first telescopic rod 212 and the second telescopic rod 222 are rotated so that the first telescopic rod 212 rotates relative to the first connecting rod 211, and the second telescopic rod 222 rotates relative to the second connecting rod 221, and the angle between the first telescopic rod 212 and the second telescopic rod 222 is rotated to form a right angle. At this time, the first telescopic rod 212 and the second telescopic rod 222 are perpendicular to the tread and the riser, respectively. The water in the water pipe is sprayed from multiple nozzles 223 onto the tread and the riser, which can ensure that the tread and the riser of the concrete staircase can be sprayed, and the spraying effect is better. When the widths of the tread and the riser are inconsistent, it can still be ensured that the tread and the riser of the concrete staircase can be sprayed, and the adaptability is stronger.

[0051] In this embodiment, the connection mechanism further includes two sliding frames 201, which are sequentially distributed along the second direction, and each sliding frame 201 is slidably disposed in the housing 100. Two first slide grooves 2011 are provided in each sliding frame 201, which are sequentially distributed along the up-down direction, and each first slide groove 2011 is disposed along the first direction.

[0052] The connecting frame 110 includes a first support rod 205, which is arranged along the second direction. A vertical rod 130 is fixedly arranged at both ends of the first support rod 205, and the vertical rod 130 is vertically arranged. Both ends of each vertical rod 130 are slidably arranged in two first sliding grooves 2011 of a sliding frame 201.

The first rotating shaft 140 is slidably arranged in the first limiting groove 2051. In each spraying assembly, the lower end of the first connecting rod 211, the lower end of the second connecting rod 221, the upper end of the first telescopic rod 212, and the upper end of the second telescopic rod 222 are all rotatably connected to the first rotating shaft 140.

[0054] In this embodiment, each vertical rod 130 is provided with a second slide groove 131, and the second slide groove 131 is vertically arranged. The connecting mechanism also includes a second support rod 206, and the second support rod 206 is arranged along the second direction. The second support rod 206 is arranged on the upper side of the first support rod 205, and the two ends of the second support rod 206 are respectively slidably arranged in the two second slide grooves 131. The second support rod 206 is provided with a second limiting groove 2061, and the second limiting groove 2061 is arranged along the second direction. The two ends of the second support rod 206 are respectively the first end and the second end. In each spray assembly, the first connecting rod 211 and the second connecting rod 221 are sequentially distributed along the direction from the first end to the second end of the second support rod 206.

In each second spray assembly, the upper end of each first connecting pipe 210 is rotatably connected to a second rotating shaft 230, and the lower end of each second connecting pipe 220 is rotatably connected to a third rotating shaft 240.

[0057] When the second support rod 206 moves downward relative to the first support rod 205, the second support rod 206 drives the first connecting tube 210 and the second connecting tube 220 to rotate through the second rotating shaft 230, thereby increasing the angle between the first connecting tube 210 and the second connecting tube 220 at the upper and lower ends.

[0058] In this embodiment, a first spring is disposed in the first telescopic rod 212. A first baffle is fixedly disposed at the upper end of the first telescopic rod 212, and the first baffle is located on the side of the first telescopic rod 212 close to the first end of the second support rod 206 along the second direction. The first baffle is used to abut against the first connecting rod 211. A first torsion spring is disposed at the connection between the first telescopic rod 212 and the first rotating shaft 140.

The second baffle 225 is located on the second end of the second telescopic rod 222 along the second direction close to the second support rod 206. The second baffle 225 is used to abut against the second connecting rod 221. A second torsion spring is disposed at the connection between the second telescopic rod 222 and the first rotating shaft 140.

[0060] The first baffle plate allows the first telescopic rod 212 to rotate only in a direction away from the second telescopic rod 222 when the first telescopic rod 212 rotates relative to the first connecting rod 211. The second baffle plate 225 allows the second telescopic rod 222 to move only in a direction away from the first telescopic rod 212 when the second telescopic rod 222 rotates relative to the second connecting rod 221. The first torsion spring allows the first telescopic rod 212 to remain parallel to the first connecting rod 211, and the second torsion spring allows the second telescopic rod 222 to remain parallel to the second connecting rod 221.

[0061] In this embodiment, the connecting mechanism also includes a third support rod 207, which is arranged along the second direction.

A third limiting groove 2071 is opened on the third support rod 207, and the third limiting groove 2071 is arranged along the second direction.

[0062] Each spray assembly further includes a third telescopic rod 250, which is vertically arranged and can be extended and retracted, and a third spring 251 is arranged in the third telescopic rod 250.

A slider 252 is fixedly arranged on the third telescopic rod 250, and the slider 252 is slidably arranged in the third limiting groove 2071.

[0063] The first support rod 205 and the second support rod 206 do not move, and when the third support rod 207 moves upward, the third telescopic rod 250 gradually shortens, and the third telescopic rod 250 drives the third rotating shaft 240 to move vertically upward. At this time, since the distance between the first support rod 205 and the second support rod 206 remains unchanged, the first connecting rod 211 and the second connecting rod 221 in each spraying assembly no longer rotate. Since the third rotating shaft 240 moves vertically upward, while the first telescopic rod 212 and the second telescopic rod 222 shorten, the first telescopic rod 212 rotates relative to the first connecting rod 211, and the second telescopic rod 222 rotates relative to the second connecting rod 221, and the first telescopic rod 212 and the second telescopic rod 222 move away from each other, and the angle between the first telescopic rod 212 and the second telescopic rod 222 increases.

[0066] In this embodiment, the driving mechanism further includes a first sensor, a first controller, a second sensor and a second controller. The first sensor and the first controller are arranged on the second cylinder 203. When the first sensor senses that each third rotating shaft 240 and a concave point on the concrete staircase are on the same vertical line, the first controller stops the movement of the second cylinder 203. The second sensor and the second controller are arranged on the fourth cylinder 208. When the second sensor senses that the first telescopic rod 212 and the second telescopic rod 222 are vertical, the second controller stops the movement of the fourth cylinder 208.

[0067] In this embodiment, a concrete curing device further includes a compensation mechanism, which includes a plurality of supplementary components, each of which is arranged on a second rotating shaft 230. Each supplementary component includes a fourth spring 302, a first supplementary ring piece 301 and two supplementary units. The two supplementary units are respectively arranged in the first connecting pipe 210 and the second connecting pipe 220. Each supplementary unit includes two second supplementary ring pieces 303 and a third torsion spring 304. The first supplementary ring piece 301 and the second supplementary ring piece 303 are truncated cone-shaped, and the thickness of the first supplementary ring piece 301 and the second supplementary ring piece 303 gradually increases along the axial direction of the second rotating shaft 230. The first supplementary ring piece 301 and the second supplementary ring piece 303 are slidably arranged on the second rotating shaft 230, and the plurality of second supplementary ring pieces 303 are sequentially distributed along the first direction.

[0068] The first supplementary ring piece 301 and the second limiting groove 2061 are offset against each other, and the fourth spring 302 connects the first supplementary ring piece 301 and the second rotating shaft 230. Each third torsion spring 304 connects two second supplementary ring pieces 303, and the second supplementary ring pieces 303 and the first connecting tube 210 or the second connecting tube 220 are offset against each other. And the third torsion spring 304 and the first connecting tube 210 or the second connecting tube 220 are offset against each other.

[0069] A first supplementary ring piece 301 and a second supplementary ring piece 303 are provided, and the first supplementary ring piece 301 is located between the second rotating shaft 230 and the second limiting groove 2061. After working for a long time, when the second rotating shaft 230, the second limiting groove 2061 and the first supplementary ring piece 301 are worn, under the action of the fourth spring 302, the first supplementary ring piece 301 is further pushed into between the second rotating shaft 230 and the second limiting groove 2061 to supplement the wear between the second rotating shaft 230 and the second limiting groove 2061, and prevent the second rotating shaft 230 and the second limiting groove 2061 from shaking. When the second rotating shaft 230, the first connecting tube 210, the second connecting tube 220 and the second supplementary ring piece 303 are worn, under the action of the third torsion spring 304, a plurality of second supplementary ring pieces 303 are respectively pushed into the first connecting tube 210 and the second connecting tube 220. Thereby, the nozzle 223 is always kept at a suitable height, and the distance between the nozzle 223 and the concrete will not change due to matching or wear gaps. The distance between the nozzle 223 and the concrete is kept consistent, and the spraying uniformity will not be affected by the drooping of the nozzle 223.

[0070] A concrete curing method comprises the following steps:

[0071] S1, in the initial state, the spray assembly is in the first state. The concrete staircase is placed flat inside the housing 100 and is located at the lower side of the spray mechanism.

[0072] Specifically, in the initial state, the fourth cylinder 208 is in a free extension state. Under the action of the third torsion spring 304, the angle between the first connecting pipe 210 and the second connecting pipe 220 at the upper and lower ends maintains a preset angle, which is the minimum angle between the first connecting pipe 210 and the second connecting pipe 220, and the preset angle is an acute angle. Under the action of the first torsion spring and the second torsion spring, the spray assembly is in the first state, the first connecting rod 211 and the first telescopic rod 212 are arranged in parallel, and the second connecting rod 221 and the second telescopic rod 222 are arranged in parallel. The concrete stairs are placed flat on the workbench 400, and the workbench 400 is pushed into the housing 100.

[0073] S2, rotate the first connecting tube 210 and the second connecting tube 220, so that the height of the first connecting tube 210 and the second connecting tube 220 in the vertical direction becomes narrower, the width along the second direction increases, and the angle between the upper and lower ends of the first connecting tube 210 and the second connecting tube 220 increases. When the lower end of each second connecting tube 220 and the intersection of two adjacent steps are in the same straight line, the first connecting tube 210 and the second connecting tube 220 are no longer rotated.

[0074] Specifically, the concrete staircase is placed flat on the workbench 400, and the second cylinder 203 is started. The second cylinder 203 drives the second support rod 206 to move downward. At this time, the second support rod 206 moves downward relative to the first support rod 205. The second support rod 206 drives the first connecting pipe 210 and the second connecting pipe 220 to rotate through the second rotating shaft 230, thereby causing the angle between the first connecting pipe 210 and the second connecting pipe 220 at the upper and lower ends to continuously increase. When the first sensor senses that each third rotating shaft 240 and a concave point on the concrete staircase are on the same vertical line, the second cylinder 203 is stopped by the first controller, and the second support rod 206 no longer moves downward. At this time, the angle between the first connecting pipe 210 and the second connecting pipe 220 at the upper and lower ends is an acute angle.

[0075] S3, then rotate the first telescopic rod 212 and the second telescopic rod 222, so that the first telescopic rod 212 rotates relative to the first connecting rod 211, and the second telescopic rod 222 rotates relative to the second connecting rod 221, and the angle between the first telescopic rod 212 and the second telescopic rod 222 is rotated to form a right angle, and the first telescopic rod 212 and the second telescopic rod 222 are respectively perpendicular to the tread and the riser.

[0076] Specifically, the fourth cylinder 208 is started, and the fourth cylinder 208 drives the third support rod 207 to move upward. Since the second support rod 206 no longer moves, the third telescopic rod 250 is shortened at this time, and the third telescopic rod 250 drives the third rotating shaft 240 to move vertically upward. At this time, since the distance between the first support rod 205 and the second support rod 206 remains unchanged, the first connecting rod 211 and the second connecting rod 221 in each spraying assembly no longer rotate. Since the third rotating shaft 240 moves vertically upward, while the first telescopic rod 212 and the second telescopic rod 222 are shortened, the first telescopic rod 212 rotates relative to the first connecting rod 211, and the second telescopic rod 222 rotates relative to the second connecting rod 221, and the first telescopic rod 212 and the second telescopic rod 222 move away from each other, and the angle between the first telescopic rod 212 and the second telescopic rod 222 increases, until the second sensor senses that the first telescopic rod 212 and the second telescopic rod 222 are vertical, and the fourth cylinder 208 stops moving through the second controller. At this time, the spraying assembly is in the second state.

[0077] After the first telescopic rod 212 and the second telescopic rod 222 are perpendicular, the first telescopic rod 212 is parallel to the riser, and the second telescopic rod 222 is parallel to the tread. At this time, when the first telescopic rod 212 and the second telescopic rod 222 are used to spray water on the concrete staircase, it can ensure that both the tread and the riser of the concrete staircase can be sprayed, and the spraying effect is better. It can also adapt to the size of the stairs. When the widths of the tread and the riser are inconsistent, it can still ensure that both the tread and the riser of the concrete staircase can be sprayed, and the adaptability is stronger.

[0078] S4, water in the water pipe is sprayed onto the treads and risers from multiple nozzles 223.

[0079] Specifically, finally, the first cylinder 202 is started, and the first cylinder 202 extends to drive the sliding frame 201 to move downward, and drives the spraying mechanism to move downward until the spraying mechanism is moved to a suitable position. The third cylinder 204 is started to drive the connecting frame 110 to reciprocate along the second direction, and the water in the water pipe is sprayed outward from each nozzle 223 to evenly spray the concrete stairs with water mist. The spraying mechanism is moved to a suitable position, thereby preventing the nozzle 223 from being too far away from the concrete stairs, resulting in low spraying efficiency, and preventing the nozzle 223 from being too close to the concrete stairs, causing the water flow to impact the output of the concrete stairs, thereby damaging the concrete stairs.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
