It aims to provide a suitable temperature and humidity environment for precast blocks, accelerate the hardening process of concrete, and improve production efficiency and product quality.

[0003] The steaming and curing chamber used in the production of concrete segments mainly utilizes the heat and humidity of steam to accelerate the hardening process of concrete segments. The cast concrete segments are placed in the steaming and curing chamber, and steam is introduced into the room through a steam supply system to increase the indoor temperature and humidity. Under suitable temperature and humidity conditions, the cement hydration reaction in the concrete is accelerated, thereby improving the early strength and performance of the concrete and shortening the production cycle of the segments.

Through the setting of the rotating component 42, the inner wall of the positioning pipe 40 is provided with a rotating component 42, and the rotating component 42 drives the sleeve 41 to rotate while swinging through the power of the rotation of the impeller 400, thereby increasing the rotation angle of the sleeve 41, and also increasing the spray range of the spray pipe 410, and further improving the uniformity of the positioning component 4 in steam curing the pipe segment.

[0042] In the above embodiments, please refer to Figure 5-Figure 7 The positioning tube 40 is movably connected to the impeller 400 through a bearing, and a rotating rod 420 is installed at the center point of the impeller 400. The power of the rotation of the impeller 400 drives the sleeve 41 to rotate and swing at the same time, thereby increasing the rotation angle of the sleeve 41 and also increasing the spray range of the spray tube 410.

[0043] In the above embodiments, please refer to Figure 5-Figure 7 A protrusion is provided at one end of the rotating rod 420, and a positioning block 421 is installed on the top of the protrusion. The rotating rod 420 is connected to the positioning block 421 to transmit the rotational power, thereby reducing the energy consumption of the equipment.

[0044] In the above embodiments, please refer to Figure 5-Figure 7 Connecting rods 422 are provided at both ends of the positioning block 421, and a first limiting block 423 is installed at the other end of the connecting rod 422, so that the positioning block 421 drives the connecting rod 422 to swing and then drives the first limiting block 423 to swing.

[0045] In the above embodiments, please refer to Figure 5-Figure 7A connecting ring 424 is sleeved on both ends of the first limiting block 423, and a second limiting block 425 is provided on the outer wall of the connecting ring 424. The second limiting block 425 is provided to effectively limit the position of the connecting ring 424, thereby improving the stability of the connecting ring 424 during swinging.

[0046] In the above embodiments, please refer to Figure 4-Figure 7 The second limit block 425 is connected to the inner wall of the positioning tube 40, and the connecting ring 424 is simultaneously sleeved on the inner walls of the first limit block 423 and the second limit block 425, which effectively limits the position of the connecting ring 424 and also controls the swing space of the first limit block 423.

[0049] In the above embodiments, please refer to Figure 1 , Figure 2 A support plate 20 is provided on the outer wall of the first connecting pipe 3, and a fixing frame 2 is provided on the other end of the supporting plate 20, which effectively improves the stability of the first connecting pipe 3 installed on the inner wall of the device body 1.

[0050] Second embodiment:

[0051] See also Figure 2 , Figure 3 The difference between the second embodiment and the first embodiment is that on the basis of retaining the first embodiment, a second connecting pipe 30 is installed at one end of the first connecting pipe 3, so that multiple groups of first connecting pipes 3 are connected to the second connecting pipe 30, which improves the uniformity of the steam entering the first connecting pipe 3, reduces the pipeline connection, and reduces the cost of the equipment.

[0052] It is too complicated to connect and install multiple groups of first connecting pipes 3 with steam equipment separately, and it is also prone to air leakage. By connecting multiple groups of first connecting pipes 3 with the second connecting pipe 30, and the other end of the second connecting pipe 30 is connected to the steam equipment, the second connecting pipe 30 uniformly transports steam to the multiple groups of first connecting pipes 3, reducing the installation and maintenance of steam equipment parts, and thereby reducing the cost of the equipment.

[0053] The present invention is in specific operation:

[0054] When the curing chamber is required to perform steam curing on the concrete pipe segment, the concrete pipe segment is first placed in the device body 1. The staff controls the steam device to send steam into the first connecting pipe 3 through the control button. The momentum of the steam spray is transmitted to the impeller 400, so that the impeller 400 rotates to drive the sleeve 41 to rotate, and the pipe segment is cured through the spray pipe 410. At the same time, when the impeller 400 rotates, the rotating rod 420 is driven to rotate, so that the positioning block 421 drives the first limit block 423 to swing through the connecting rod 422, and one end of the first limit block 423 is connected to the sleeve 41, thereby driving the sleeve 41 to rotate and swing at the same time, expanding the rotation angle of the spray pipe 410, so that the spray pipe 410 sprays and cures the pipe segment in multiple dimensions, thereby improving the uniformity of temperature and humidity in the device body 1;

[0055] Further, multiple groups of first connecting pipes 3 are installed at both ends of the device body 1, and multiple groups of sleeves 41 are installed at one end of the first connecting pipe 3, and the first connecting pipes 3 are sequentially located at the upper, middle and lower positions in the device body 1, and the sleeves 41 in the top first connecting pipe 3 are downwardly facing, and the sleeves 41 in the bottom first connecting pipe 3 are upwardly facing, and the middle first connecting pipe 3 is cross-arranged with the upper and lower sleeves 41, which effectively improves the uniformity of temperature and humidity in the device body 1 when the sleeves 41 are used to maintain the pipe segments;

[0056] Secondly, a second connecting pipe 30 is installed at one end of the multiple groups of first connecting pipes 3, and a steam device is installed at the other end of the second connecting pipe 30, which reduces the installation and maintenance of connecting parts between the steam equipment and the first connecting pipe 3, reduces the cost of the equipment, and secondly improves the uniformity of the steam temperature and humidity in the first connecting pipe 3.

[0057] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention.
