Description

Technical Field

[0001] The utility model relates to the technical field of concrete curing, and in particular to steam curing equipment for large prefabricated concrete components. Background Art

[0002] After the initial setting of concrete, in order to provide a constant high humidity and suitable temperature environment, promote the full reaction of cement, accelerate the hardening process of concrete, and improve the strength and durability of prefabricated parts, it is often necessary to spray steam or water on the solidified concrete prefabricated parts.

[0003] The existing steam curing method is that workers use the spray pipe of a handheld steam generator to spray the surface of the precast concrete parts. This method is often slow, and because the nozzle of the spray pipe is often vertical, the range of the steam and water sprayed out is like a flashlight. As a result, when the precast concrete parts are relatively large, part of them cannot be sprayed. Even if the spray pipe is moved, it is difficult to ensure that the spraying time and spraying amount are consistent, resulting in uneven spraying. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the existing steam curing is that the staff uses the spray pipe of the steam generator to spray the surface of the concrete precast part. This method is often slow, and because the spray port of the spray pipe is often vertical, the range of the steam and water sprayed out is like the light of a flashlight. This results in that when the concrete precast part is relatively large, part of it cannot be sprayed, and even if the spray pipe is moved, it is difficult to ensure that the spraying time and spraying amount are the same, resulting in uneven spraying.

[0005] Therefore, based on the above-mentioned problem, the present invention proposes a steam curing device for large prefabricated concrete components, including a placement rack, a roller fixedly installed at the bottom of the placement rack, an existing steam generator placed on one side of the placement rack, the steam generator is connected to a conveying pipe, a uniform spraying assembly is fixedly installed on the upper part of the placement rack, the uniform spraying assembly is connected to the conveying pipe, and the uniform spraying assembly sprays steam evenly on the concrete prefabricated parts on the upper part of the placement rack.

[0006] Preferably: the uniform spray assembly includes: a bracket, a steam generator, a bracket placed on one side, a placement rack at the bottom of the bracket, a delivery pipe fixedly connected to one side of the bracket, the end of the delivery pipe is sealed, and four side pipes are fixedly connected to one side of the seal, each side pipe is rotatably connected to a spray plate through an oil seal bearing, the inside of the spray plate is hollow, and a plurality of spray holes are provided at the bottom of the spray plate.

The installation positions of the four limit hollow blocks are located beside the four limit grooves, and a moving rod is sleeved inside the limit hollow block, and the moving rod moves laterally in the limit hollow block.

[0008] Beneficial effect: When the piston rod of the electric push rod moves back and forth, driving the four limit hollow blocks of the sliding cylinder to move downward, the movement of the limit hollow blocks will indirectly drive their respective moving rods to swing up and down, thereby indirectly driving the four spray plates to swing up and down, making the spray coverage area larger and making the spraying on the surface of the concrete prefabricated parts more uniform.

DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] Preferably: the uniform spraying assembly includes: a bracket 3, a steam generator 2, a bracket 3 is placed on one side, a placement rack 1 is provided at the lower part of the bracket 3, a delivery pipe 201 is fixedly connected to one side of the bracket 3, the end of the delivery pipe 201 is sealed, and four side pipes 202 are fixedly connected to one side of the seal, each side pipe 202 is rotatably connected to a spray plate 203 through an oil seal bearing, the spray plate 203 is hollow inside, and a plurality of spray holes are provided at the lower part of the spray plate 203, the prefabricated concrete parts are placed on the placement rack 1, and then the placement rack 1 is moved so that the placement rack 1 is located at the lower part of the bracket 3, and then the steam generator 2 is started, at this time the steam generator 2 transports steam and water vapor together and places them on the delivery pipe 201, and then transports them to the fixedly connected side pipe 202 and the indirectly rotatably connected spray plate 203, and then sprayed on the prefabricated concrete parts through the spray holes provided at the lower part of the spray plate 203.

[0017] Preferably: each spray plate 203 is fixedly connected to a moving rod 204, an electric push rod 301 is fixedly installed on the upper part of the bracket 3, the piston rod of the electric push rod 301 is connected to the sliding cylinder 302, four limiting grooves 303 are provided on the outside of the sliding cylinder 302, and side tubes 202 that move up and down are placed inside the limiting grooves 303, and four limiting hollow blocks 304 are also provided on the outside of the sliding cylinder 302. The four limiting hollow blocks 304 are installed beside the four limiting grooves 303, and the moving rod 204 is sleeved inside the limiting hollow blocks 304. The moving rod 204 moves horizontally on the limiting hollow blocks 304, and the electric push rod 301 is started to make the piston of the electric push rod 301 As the rod moves back and forth, the up and down movement of the piston rod of the electric push rod 301 drives the sliding cylinder 302 to move up and down. Since the side of the sliding cylinder 302 is provided with four limiting hollow blocks 304, the limiting hollow blocks 304 are sleeved with the moving rod 204, and because the limiting groove 303 is connected to the side tube 202 for sliding up and down, when the sliding cylinder 302 moves up and down, it will drive the four limiting hollow blocks 304 to move up and down, thereby indirectly driving their respective moving rods 204 to swing up and down, thereby indirectly driving the four spray plates 203 to swing up and down, so that the spray coverage area is larger and the spraying on the surface of the concrete precast part is more uniform.

[0018] Working principle: When in use, place the prefabricated concrete part on the placement rack 1, then move the placement rack 1 so that it is located at the bottom of the bracket 3, and then start the steam generator 2. At this time, the steam generator 2 transports the steam and water vapor together and places them on the conveying pipe 201, and then transports them to the fixedly connected side pipe 202 and the indirectly rotating spray plate 203, and then sprays them on the prefabricated concrete part through the spray holes provided at the bottom of the spray plate 203. In order to make the spraying more uniform, the electric push rod 301 can be started at this time to move the piston rod of the electric push rod 301 back and forth, and the piston rod of the electric push rod 301 moves up and down. It will drive the sliding cylinder 302 to move up and down. Since four limiting hollow blocks 304 are provided on the side of the sliding cylinder 302, the limiting hollow blocks 304 are sleeved with the moving rod 204, and because the limiting groove 303 is connected to the side tube 202 for sliding up and down, when the sliding cylinder 302 moves up and down, it will drive the four limiting hollow blocks 304 to move up and down, thereby indirectly driving their respective moving rods 204 to swing up and down, thereby indirectly driving the four spray plates 203 to swing up and down, so that the spray coverage area is larger, and when the spray plate 203 moves up, the spraying on the surface of the concrete precast part is more uniform.
