Description

Technical Field

[0001] This invention relates to the field of concrete curing technology, and specifically to a concrete curing device for construction in logistics parks. Background Technology

[0002] In the construction of large buildings such as logistics parks, the curing of concrete structures is a crucial step in ensuring their strength and durability. Concrete needs to be kept moist for a certain period after pouring to prevent premature water loss, which could lead to cracking or insufficient strength.

[0003] Traditional concrete curing relies heavily on manual watering or covering with moisture-retaining materials, which is not only inefficient and uses a lot of water, but also makes it difficult to ensure the uniformity and continuity of curing, especially on vertical structures such as facade walls.

[0004] Currently, some automated curing equipment exists on the market, such as spray systems or mobile spraying devices. However, most existing equipment relies on tracks or guide structures for movement, which typically suffers from poor adaptability, inability to flexibly adapt to different scaffold heights and layouts, and difficulty in turning. Furthermore, most devices lack intelligent reversing functions, requiring manual intervention to adjust the direction of movement, increasing operational complexity and labor intensity. Regarding curing agent spraying, existing equipment often suffers from unstable material supply, uneven spraying pressure, and the inability to automatically replenish material during movement, resulting in poor spray coverage and affecting curing quality. Therefore, there is an urgent need for a concrete curing device that can adapt to scaffold tracks, achieve automatic reciprocating movement, and precisely control curing agent spraying to meet the efficient and high-quality curing needs of large construction sites such as logistics parks.

[0030] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0031] refer to Figures 1-10 A concrete curing device for construction of a logistics park includes a main structure for erection, the main structure including scaffolding 101, a moving mechanism for movement and a curing mechanism for spraying curing agent onto the concrete wall.

[0032] The moving mechanism includes a moving frame 201, a guide rod 205 fixedly mounted on the moving frame 201, a traveling wheel 202 rotatably mounted on the guide rod 205, and a crank rod 212 rotatably mounted on the scaffold 101.

[0033] like Figure 2 , Figure 3As shown, the main structure includes a track module mounted on the scaffold 101. The track module is composed of multiple vertical tracks 102, turning tracks 103, and horizontal tracks 104 spliced ​​together. The vertical tracks 102, turning tracks 103, and horizontal tracks 104 are all fixedly installed on the scaffold 101. Each of the vertical tracks 102, turning tracks 103, and horizontal tracks 104 is provided with a guide groove 105. The guide rod 205 slides in the guide groove 105. The guide grooves 105 on all the vertical tracks 102, turning tracks 103, and horizontal tracks 104 are connected. The traveling wheel 202 rolls along the vertical tracks 102, turning tracks 103, and horizontal tracks 104. The two outermost vertical tracks 102 are fixedly installed with connecting blocks 106 below them.

[0034] When the traveling wheel 202 rotates, it rolls along the vertical track 102, the turning track 103 and the horizontal track 104. The guide rod 205 slides in the guide groove 105, and at the same time the ball bearing 204 rolls along the surface of the vertical track 102, the turning track 103 and the horizontal track 104 to reduce friction, thereby driving the mobile frame 201 and the maintenance agent box 301 to move along the track module. Depending on the different scaffolding 101, track modules of different lengths and heights are erected.

[0035] like Figures 4-7 As shown, the moving mechanism also includes a sliding frame 206 that is slidably installed in the moving frame 201. A lower friction wheel 207 and an upper friction wheel 221 are rotatably installed on the sliding frame 206. A lower mating gear 208 is fixedly installed on the lower friction wheel 207, and an upper mating gear 220 is fixedly installed on the upper friction wheel 221.

[0036] like Figures 4-7 As shown, the sliding frame 206 is provided with two conical slots 224, and the moving frame 201 is slidably mounted with a conical block 222. A block spring 223 is provided between the conical block 222 and the moving frame 201. When the lower friction wheel 207 is in contact with the walking wheel 202, the conical block 222 is inserted into the conical slot 224. When the upper friction wheel 221 is in contact with the walking wheel 202, the conical block 222 is inserted into the other conical slot 224.

[0037] like Figures 4-7As shown, a motor 203 is fixedly installed on the movable frame 201. A crank 212 is fixedly installed on the motor shaft of the motor 203. A central gear 213 is fixedly installed on the crank 212. An intermediate gear 215 is rotatably installed inside the movable frame 201. A central transmission belt 214 is wound around the central gear 213 and the intermediate gear 215. An upper transmission gear 210 is fixedly installed on the intermediate gear 215. A lower transmission gear 209 is rotatably installed on the movable frame 201. A lower transmission belt 211 is wound around the upper transmission gear 210 and the lower transmission gear 209. The lower transmission gear 209 meshes with the lower mating gear 208.

[0038] like Figures 4-7 As shown, a steering gear 216 and an upper gear 217 are rotatably mounted on the movable frame 201 via a drive shaft. The steering gear 216 meshes with the upper transmission gear 210. An upper transmission gear 218 is rotatably mounted inside the movable frame 201. An upper transmission belt 219 is wound around the upper gear 217 and the upper transmission gear 218. The upper transmission gear 218 meshes with the upper mating gear 220. Multiple ball bearings 204 are rotatably mounted on the movable frame 201.

[0039] Motor 203 drives crank 212 and center gear 213 to rotate. Center gear 213 drives intermediate gear 215 and upper transmission gear 210 to rotate via center transmission belt 214. Upper transmission gear 210 drives lower transmission gear 209 to rotate via lower transmission belt 211. Lower transmission gear 209 drives lower mating gear 208 and lower friction wheel 207 to rotate. Simultaneously, upper transmission gear 210 drives steering gear 216 and upper gear 217 to rotate. Upper gear 217 drives upper transmission gear 218 to rotate via upper transmission belt 219. Upper transmission gear 218 drives upper mating gear 220 and upper friction wheel 221 to rotate. The rotation of upper friction wheel 221... The direction of movement is opposite to the rotation direction of the lower friction wheel 207. In the initial state, the lower friction wheel 207 is in contact with the traveling wheel 202. The lower friction wheel 207 drives the traveling wheel 202 to rotate through friction transmission. The rotation of the traveling wheel 202 causes the moving frame 201 to move along the vertical track 102, the turning track 103 and the horizontal track 104. When the moving frame 201 moves to the tail end of the track module, the docking block 106 at the tail end of the track module contacts the sliding frame 206. The docking block 106 pushes the sliding frame 206 to slide along the moving frame 201, causing the conical locking block 222, which was originally in the conical slot 224, to slide out. The locking block spring 223 is compressed, and then when the conical locking block... When the 222 reaches another conical slot 224, the locking spring 223 rebounds, causing the conical locking block 222 to insert into the other conical slot 224. The sliding frame 206 slides, causing the lower friction wheel 207 to disengage from the traveling wheel 202. The upper friction wheel 221 begins to engage with the traveling wheel 202. Subsequently, the upper friction wheel 221 rotates, driving the traveling wheel 202 to rotate in the opposite direction, thereby causing the moving frame 201 to move back along the vertical track 102, the turning track 103, and the horizontal track 104. When the moving frame 201 moves back to the starting end of the track module, the docking block 106 at the starting end of the track module contacts the sliding frame 206. Similarly, the conical locking block... Block 222 is pushed into another conical slot 224, causing the upper friction wheel 221 to disengage from the traveling wheel 202, and the lower friction wheel 207 to re-engage with the traveling wheel 202. At this time, the traveling wheel 202 reverses direction again, and so on, so that the moving frame 201 can move back and forth along the track module continuously. Since both the conical block 222 and the conical slot 224 are provided with conical surfaces, in conjunction with the rebound force of the block spring 223, the connecting block 106 contacts the sliding frame 206. The moving frame 201 has a certain inertia, so when the lower friction wheel 207 or the upper friction wheel 221 disengages from the traveling wheel 202, the upper friction wheel 221 or the lower friction wheel 207 quickly engages with the traveling wheel 202.

[0040] like Figures 8-10As shown, the maintenance mechanism includes a maintenance agent tank 301 fixedly installed on a movable frame 201. The maintenance agent tank 301 is provided with multiple nozzles 304 facing different directions. An inner push plate 305 is slidably installed inside the maintenance agent tank 301. An outer rotating rod 306 is rotatably installed on the inner push plate 305. The outer rotating rod 306 is rotatably installed with the crank rod 212.

[0041] like Figures 8-10 As shown, an opening and closing cylinder 302 is fixedly installed below the maintenance agent tank 301, and an inlet pipe 303 is fixedly installed below the opening and closing cylinder 302. The inlet pipe 303 is connected to the external maintenance agent. A sealing plug 312 is slidably installed inside the opening and closing cylinder 302, and a sealing spring 313 is provided between the sealing plug 312 and the opening and closing cylinder 302.

[0042] like Figures 8-10 As shown, a pressing block 307 is rotatably installed inside the maintenance agent tank 301. A torsion spring 308 is provided between the pressing block 307 and the maintenance agent tank 301. A pressing rod 309 is slidably installed below the maintenance agent tank 301. A pressing spring 310 is provided between the pressing rod 309 and the maintenance agent tank 301. A rotating rod 311 is rotatably installed below the maintenance agent tank 301. The lower end of the pressing rod 309 contacts the rotating rod 311, and the lower end of the sealing plug 312 contacts the rotating rod 311.

[0043] When the crank lever 212 rotates, it drives the inner push plate 305 to slide back and forth in the curing agent tank 301 via the outer rotating rod 306. When the inner push plate 305 moves toward the nozzle 304, it pushes the curing agent in the curing agent tank 301 into the nozzle 304, and sprays it onto the concrete wall surface through the nozzles 304 at different angles for curing. When the inner push plate 305 moves away from above the pressing block 307, the torsion spring 308, which is in a torsional state, rebounds, causing the pressing block 307 to stand upright. At this time, the downward pressure spring 310, which is in a stretched state, rebounds, causing the downward pressure rod 309 to rise, thereby allowing the compression sealing spring 313, which is in a compressed state, to rebound. The sealing plug 312 descends, the rotating rod 311 rotates, and the descending sealing plug 312 blocks the inlet pipe 303, preventing external curing agent from continuing to enter the curing agent tank 301. When the inner push plate 305 moves toward the nozzle 304, the inlet pipe 303 is closed. The inner push plate 305 moves away from the nozzle 304. After the inner push plate 305 contacts the pressing rotating block 307, it pushes the pressing rotating block 307 to rotate, the torsion spring 308 is twisted, the pressing rotating block 307 presses down the pressing rod 309, the pressing spring 310 is stretched, the pressing rod 309 drives the rotating rod 311 to rotate, the rotating rod 311 drives the sealing plug 312 to rise, the sealing spring 313 is compressed, the sealing plug 312 no longer blocks the inlet pipe 303, so that the external maintenance agent can smoothly pass through the inlet pipe 303 and the opening and closing cylinder 302 into the maintenance agent tank 301. Then the inner push plate 305 moves toward the nozzle 304 again, and so on, in coordination with the movement of the moving frame 201 on the track module, continuously spraying the maintenance agent onto the concrete wall.

[0044] The working principle of the concrete curing device for logistics park construction disclosed in this invention is as follows:

[0045] Motor 203 drives crank 212 and center gear 213 to rotate. Center gear 213 drives intermediate gear 215 and upper transmission gear 210 to rotate via center transmission belt 214. Upper transmission gear 210 drives lower transmission gear 209 to rotate via lower transmission belt 211. Lower transmission gear 209 drives lower mating gear 208 and lower friction wheel 207 to rotate. Simultaneously, upper transmission gear 210 drives steering gear 216 and upper gear 217 to rotate. Upper gear 217 drives upper transmission gear 218 to rotate via upper transmission belt 219. Upper transmission gear 218 drives upper mating gear 220 and upper friction wheel 221 to rotate. The rotation direction of upper friction wheel 221 is opposite to the rotation direction of lower friction wheel 207. Initial state The lower friction wheel 207 is in contact with the traveling wheel 202. The lower friction wheel 207 drives the traveling wheel 202 to rotate through friction transmission. The rotation of the traveling wheel 202 causes the moving frame 201 to move along the vertical track 102, the turning track 103, and the horizontal track 104. At the same time, the guide rod 205 slides in the guide groove 105, and the ball bearings 204 roll along the surfaces of the vertical track 102, the turning track 103, and the horizontal track 104 to reduce friction. This causes the moving frame 201 and the maintenance agent tank 301 to move along the track module. When the moving frame 201 moves to the end of the track module, the docking block 106 at the end of the track module contacts the sliding frame 206. The docking block 106 pushes the sliding frame 206 to slide along the moving frame 201. This causes the conical block 222, originally in the conical slot 224, to slide out, compressing the block spring 223. Then, when the conical block 222 reaches another conical slot 224, the block spring 223 rebounds, causing the conical block 222 to insert into the other conical slot 224. The sliding frame 206 slides, causing the lower friction wheel 207 to disengage from the traveling wheel 202, and the upper friction wheel 221 to begin engaging with the traveling wheel 202. The upper friction wheel 221 then rotates, driving the traveling wheel 202 to rotate in the opposite direction, thereby causing the moving frame 201 to move back along the vertical track 102, the turning track 103, and the horizontal track 104. When the moving frame 201 moves back to the starting end of the track module, the starting end of the track module... The docking block 106 contacts the sliding frame 206. Similarly, the conical locking block 222 is pushed into another conical locking groove 224, causing the upper friction wheel 221 to disengage from the traveling wheel 202, and the lower friction wheel 207 to re-engage with the traveling wheel 202. At this time, the traveling wheel 202 reverses direction again. This process is repeated to make the moving frame 201 move back and forth along the track module. Since both the conical locking block 222 and the conical locking groove 224 are provided with conical surfaces, in conjunction with the rebound force of the locking block spring 223, the docking block 106 contacts the sliding frame 206. The moving frame 201 has a certain inertia. Therefore, when the lower friction wheel 207 or the upper friction wheel 221 disengages from the traveling wheel 202, the upper friction wheel 221 or the lower friction wheel 207 quickly engages with the traveling wheel 202.When the crank lever 212 rotates, the outer rotating rod 306 drives the inner push plate 305 to slide back and forth within the curing agent tank 301. When the inner push plate 305 moves toward the nozzle 304, it pushes the curing agent in the curing agent tank 301 into the nozzle 304, and sprays it onto the concrete wall surface through the nozzles 304 at different angles for curing. When the inner push plate 305 moves away from above the pressing block 307, the torsion spring 308, which is in a torsional state, rebounds, causing the pressing block 307 to stand upright. At this time, the downward pressure spring 310, which is in a stretched state, rebounds, causing the downward pressure rod 309 to rise. This allows the compression sealing spring 313, which is in a compressed state, to rebound, causing the sealing plug 312 to descend. The rotating rod 311 rotates, and the descending sealing plug 312 blocks the inlet pipe 303, preventing external curing agent from continuing to enter the curing agent tank 301. When the inner push plate 305 moves toward the nozzle 304, the inlet pipe 303 is closed. The inner push plate 305 moves away from the nozzle 304. After the inner push plate 305 contacts the pressing rotating block 307, it pushes the pressing rotating block 307 to rotate, the torsion spring 308 is twisted, the pressing rotating block 307 presses down the pressing rod 309, the pressing spring 310 is stretched, the pressing rod 309 drives the rotating rod 311 to rotate, the rotating rod 311 drives the sealing plug 312 to rise, the sealing spring 313 is compressed, the sealing plug 312 no longer blocks the inlet pipe 303, so that the external maintenance agent can smoothly pass through the inlet pipe 303 and the opening and closing cylinder 302 into the maintenance agent tank 301. Then the inner push plate 305 moves toward the nozzle 304 again, and so on, in coordination with the movement of the moving frame 201 on the track module, continuously spraying the maintenance agent onto the concrete wall.
