DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-Figure 4 As shown, the technical solution adopted by the present invention is as follows: the curing equipment for precast concrete parts includes a steam curing shell 1 and a steam curing bearing mechanism.

[0031] A steam input pipe 2 is installed on the curing shell 1, and the steam input pipe 2 is connected to an external steam generator. The steam generator delivers steam to the curing shell 1. A pressure sensor and a temperature transmitter are provided in the curing shell 1 to detect the air pressure and temperature in the curing shell 1. When the preset temperature and air pressure in the curing shell 1 are reached, steam is continuously delivered to the curing shell 1 for a period of time to complete the curing of the precast concrete parts. A pressure balance one-way valve is installed on the curing shell 1 to maintain a suitable pressure in the curing shell 1.

[0032] A material opening is provided on the curing shell 1, and a shielding component for shielding the material opening is provided on the curing shell 1. The shielding component shields the material opening, thereby making the curing shell 1 in a sealed state.

[0033] The shielding assembly includes a baffle 3, which is set at the material inlet for opening and closing. Specifically, a fixing block 5 is fixedly installed on the steaming shell 1, and a first electric push rod 4 is fixedly installed on the fixing block 5. The baffle 3 is fixedly connected to the telescopic end of the first electric push rod 4. The first electric push rod 4 drives the baffle 3 to move, thereby opening or closing the baffle 3.

[0034] In this embodiment, there are two material openings, which are symmetrically arranged on both sides of the steam curing shell 1. Each material opening is equipped with a shielding component. One of the material openings is a feed opening 17, and the other is a discharge opening 18.

[0035] The steam curing bearing mechanism is arranged in the steam curing shell 1. The steam curing bearing mechanism includes a transmission assembly and a steam curing bearing frame 16 for placing the precast concrete parts. There are two transmission assemblies, and the two transmission assemblies are symmetrically arranged in the steam curing shell 1. Each transmission assembly includes a first transmission wheel 10, a second transmission wheel 20, a third transmission wheel 21 and a transmission belt 11. The axes of the first transmission wheel 10, the second transmission wheel 20, and the third transmission wheel 21 are parallel to each other. The first transmission wheel 10, the second transmission wheel 20, and the third transmission wheel 21 are distributed in a triangle and are all rotatably arranged in the steam curing shell 1.

[0036] The second transmission wheel 20 is elastically connected to the top wall of the steaming shell 1 for vertical movement.

[0037] Specifically, an elastic telescopic member 19 is fixedly installed on the top wall of the steaming shell 1, and the telescopic end of the elastic telescopic member 19 is vertically downward. The telescopic end of the elastic telescopic member 19 is rotatably connected to the second rotating shaft 24 through a second bearing 23, and the second rotating shaft 24 is coaxially fixedly connected to the second transmission wheel 20.

[0038] The elastic expansion member 19 includes a fixed cylinder 1901, a slide bar 1902 and a spring 1903. The upper end of the fixed cylinder 1901 is fixedly connected to the steam curing shell 1, the slide bar 1902 is slidably connected in the fixed cylinder 1901, and the lower end of the slide bar 1902 is connected to the second bearing 23. A spring groove is vertically provided on the slide bar 1902, and the spring 1903 is arranged in the spring groove, and one end of the spring 1903 is fixedly connected to the fixed cylinder 1901, and the other end of the spring 1903 is fixedly connected to the slide bar 1902.

[0039] The first transmission wheel 10 is arranged in cooperation with the feed port 17, and the third transmission wheel 21 is arranged in cooperation with the discharge port 18. The first transmission wheel 10 and the third transmission wheel 21 are both arranged in the steaming shell 1 for horizontal movement.

[0040] The transmission assembly also includes a motor 9. Specifically, a first connecting member 8 is horizontally movable in the steam curing shell 1, the motor 9 is fixedly connected to the first connecting member 8, and the motor shaft of the motor 9 is coaxially fixedly connected to the first transmission wheel 10. A connecting block 6 is fixedly installed on the bottom wall of the steam curing shell 1, and a second electric push rod 7 is fixedly connected to one side of the connecting block 6, and the telescopic end of the second electric push rod 7 is fixedly connected to the first connecting member 8. When the second electric push rod 7 is extended, the first transmission wheel 10 moves toward the direction close to the feed port 17.

[0041] A second connecting member 13 is horizontally movable in the steam curing shell 1, and a first rotating shaft 22 is rotatably mounted on the second connecting member 13 through a first bearing 14, and a third transmission wheel 21 is coaxially fixedly connected to the first rotating shaft 22. A third electric push rod 12 is fixedly mounted on the connecting block 6, and a telescopic end of the third electric push rod 12 is fixedly connected to the second connecting member 13. When the third electric push rod 12 is extended, the third transmission wheel 21 moves toward the direction close to the discharge port 18.

[0042] There are a plurality of steaming and curing racks 16, which are all rotatably connected between the two transmission belts 11 through the fixing rod 15, and the plurality of steaming and curing racks 16 are arranged at intervals along the transmission direction of the transmission belt 11. When the transmission belt 11 moves, the steaming and curing racks 16 rotate around the axis of the fixing rod 15 under the action of their own gravity, so that the fixing rod 15 is always in a horizontal state.

[0043] Working principle: Initially, the steam curing bearing mechanism is completely in the steam curing housing 1, and the transmission belt 11 is an isosceles triangle. At this time, one of the steam curing bearing frames 16 is at the first transmission wheel 10.

[0044] The precast concrete parts are mounted on the steam curing carrier 16. The corresponding first electric push rod 4 is started to move the baffle 3, thereby opening the feed port 17. The second electric push rod 7 is started to extend, and the second electric push rod 7 pushes the motor 9 and the first transmission wheel 10 to move toward the feed port 17. At the same time, the first transmission wheel 10 drives the second transmission wheel 20 to move downward through the transmission belt 11, and the slide bar 1902 overcomes the elastic force of the spring 1903 and moves downward.

[0045] The steam curing support frame 16 at the first transmission wheel 10 moves outward through the feeding port 17 until it is at the feeding position, and the bearing surface of the steam curing support frame 16 at the feeding position is on the same horizontal plane as the center of the first transmission wheel 10. Then the precast concrete parts are placed on the steam curing support frame 16 at the feeding position.

[0046] Of course, the feed inlet can be matched with the outlet of a precasting machine for producing precast concrete parts. When the steam-curing carrier 16 is at the feed position, the precasting machine can directly transport the precast concrete parts to the steam-curing carrier 16 at the feed position.

[0047] Afterwards, the motor 9 is started, the first transmission wheel 10 rotates, the transmission belt 11 moves, the curing carrier 16 loaded with the precast concrete parts is removed from the feeding position, and the next curing carrier 16 is moved to the feeding position, and then the next precast concrete part is placed on the corresponding curing carrier 16.

[0048] The precast concrete parts are placed on the multiple steaming and curing racks 16 in sequence. After the loading is completed, the second electric push rod 7 is started to shorten the second electric push rod 7, thereby retracting the motor 9 into the steaming and curing housing 1, and returning the first transmission wheel 10 to the initial position. Under the action of the spring 1903, the fixing cylinder 1901 slides upward, thereby putting the transmission belt 11 in a tensioned state.

[0049] Then, by starting the first electric push rod 4, the first electric push rod 4 drives the baffle 3 to move and cover the feed inlet 17. At this time, the steaming and curing shell 1 is in a closed state.

[0050] Steam is injected into the curing shell 1 through the steam input pipe 2. When the preset temperature and air pressure in the curing shell 1 are reached, steam is transported into the curing shell 1 and maintained for a period of time to complete the curing of the precast concrete parts.

[0051] After the curing is completed, the discharge port 18 is opened. The third electric push rod 12 is started to extend the third electric push rod 12, so that the third transmission wheel 21 moves toward the discharge port 18, so that the curing support frame 16 at the third transmission wheel 21 extends outside the discharge port 18, that is, it is in the unloading position, and the bearing surface of the curing support frame 16 at the unloading position is on the same horizontal plane as the axis of the third transmission wheel 21. The precast concrete parts on the curing support frame 16 at the unloading position are removed. Then, the motor 9 is started, and the transmission belt 11 moves, so that the next curing support frame 16 loaded with precast concrete parts moves to the unloading position to facilitate unloading. In this way, all the precast concrete parts in the curing shell 1 are removed, and the unloading is completed.

[0052] After the unloading is completed, the third electric push rod 12 is started, and the steaming and curing bearing mechanism returns to the initial state.

[0053] The method for using the curing equipment for precast concrete parts of the present invention comprises the following steps:

[0054] S1, open the material port, move the first transmission wheel 10 toward the discharge port, and move the second transmission wheel 20 downward; the steam curing support frame 16 located at the first transmission wheel 10 cooperates with the material port; and then place the precast concrete parts on the steam curing support frame 16.

[0055] S2, moving the transmission belt 11 to make the next steam-curing carrier 16 match with the material opening and place the precast concrete parts thereon; placing the precast concrete parts on multiple steam-curing carriers 16 in this way.

[0056] S3. After the precast concrete parts are placed, the first transmission wheel 10 is moved to return the curing bearing mechanism to the curing shell 1, and the material opening is closed by the shielding component.

[0057] S4. Thereafter, steam is input into the steam curing shell 1 through the steam input pipe 2 to cure the precast concrete parts in the steam curing shell 1.

[0058] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
