Description

Technical Field

[0001] The invention relates to the technical field of transportation, and in particular to a system and method for conveying prefabricated concrete parts. Background Art

[0002] With the rapid development of the construction and railway industries, the demand for precast concrete parts is increasing. The efficiency and automation level of the precast concrete production line directly affect the production cost and product quality.

[0003] like Figure 1 and Figure 2 As shown, the existing concrete precast production line includes a pouring pretreatment station, a pouring station, a curing kiln A, a curing kiln B, and a demoulding and cleaning station. Among them, the layout of the mold platform for the curing kiln A and the curing kiln B is nine layers and four rows (each layer and each row can be placed on the mold platform), and the bottom layer of each row of the curing kiln A and the curing kiln B is overhead and corresponds to each other. During production, the mold platform passes through several pre-casting treatment stations for placing steel cages, spraying demoulding oil and other processes, and then the mold platform passes through the pouring station, the curing kiln A, the curing kiln B, and the demoulding and cleaning station in turn. The mold platform is demoulded and cleaned at the demoulding and cleaning station. The demoulding mold platform passes through the bottom layer of the first row of the curing kiln B, the bottom layer of the first row of the curing kiln A, the pre-casting treatment station, and the pouring station in turn to realize the recycling of the mold platform.

[0004] When the mold pallet is transferred from curing kiln A to curing kiln B, the three key processes of taking out the mold pallet from the bottom layer of curing kiln A, transferring the mold pallet and storing the mold pallet in the bottom layer of curing kiln B are performed by the mold pallet storage and retrieval machine; because the mold pallet storage and retrieval machine also needs to execute the process of transporting the demolded mold pallet from the bottom layer of the first row of curing kiln B to the bottom layer of the first row of curing kiln A, these processes often have waiting queues, resulting in limited production efficiency.

[0005] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art known to those skilled in the art.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0081] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0082] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0083] See also Figure 1 to Figure 10 The present application provides a conveying system for precast concrete parts, including a casting pretreatment station 1, a casting station 2, an A curing kiln 3, a B curing kiln 4, a demolding and cleaning station 5 and a mold platform recovery channel 6, through which a mold supply platform 9 passes in sequence.

[0084] The pouring pre-treatment station 1 is used to place a steel cage, spray demoulding oil, and other operations on the demoulding platform 9.

[0085] The pouring station 2 is used to pour concrete in the mold platform 9 after completing the processes of placing the steel cage and spraying the demoulding oil.

[0086] The layout of the A curing kiln 3 for placing the mold platforms 9 is multi-layered and multi-row (nine layers and four rows). Specifically, the A curing kiln 3 includes the A kiln first row 31, the A kiln second row 32, the A kiln third row 33 and the A kiln fourth row 34. Each of the above rows has nine layers, and the bottom layer of each row is suspended to form a passage. The mold platforms 9 of each row and layer in the A curing kiln 3 are taken out one by one from the passage of the bottom layer of each row.

[0087] The B curing kiln 4 is arranged with multiple layers and multiple rows (nine layers and four rows) for placing the mold tables 9. Specifically, the B curing kiln 4 includes a first row 41 of the B kiln, a second row 42 of the B kiln, a third row 43 of the B kiln, and a fourth row 44 of the B kiln. Each of the above rows has nine layers, and the lowest layer of each row is suspended to form a passage. The mold tables 9 of each row and layer in the B curing kiln 4 are taken out one by one from the lowest channel of each row.

[0088] The channels at the bottom of each column of curing kiln B 4 and curing kiln A 3 correspond one to one, and the mold table 9 in curing kiln A 3 is transported to curing kiln B 4 through the mold table storage and retrieval machine 7. For example, the mold table 9 at the bottom of the first column 31 of kiln A is transported to the bottom of the first column 41 of kiln B through the mold table storage and retrieval machine 7.

[0089] A translation guide rail 71 is arranged on the ground between the B curing kiln 4 and the A curing kiln 3, and the mold table storage and retrieval machine 7 can move along the translation guide rail 71 to perform the actions of taking out the mold table 9 from the bottom layer of each column of the A curing kiln 3, transferring the mold table 9 and storing the mold table 9 in the bottom layer of each column of the B curing kiln 4.

[0090] The demoulding and cleaning station 5 is used to demould and clean the mold table 9 from the B curing kiln 4.

[0091] The mold recovery channel 6 passes through the bottom layer of the first row 41 of the B kiln and the bottom layer of the first row 31 of the A kiln in sequence, and is used to transport the mold 9 from the demolding and cleaning station 5 to the pre-casting treatment station 1. A ferry device 8 for transporting the mold 9 is provided in the mold recovery channel 6, and the ferry device 8 can be raised and lowered. The ferry device 8 can transport the mold 9 throughout the entire process between the demolding and cleaning station 5 and the pre-casting treatment station 1; the ferry device 8 can also be used only to transport the mold 9 from the bottom layer of the first row 41 of the B kiln to the bottom layer of the first row 31 of the A kiln. The present application does not limit the method of transferring the mold 9 from the demolding and cleaning station 5 to the bottom layer of the first row 41 of the B kiln, nor does it limit the method of transferring the mold 9 from the bottom layer of the first row 31 of the A kiln to the pre-casting treatment station 1.

[0092] The mold recovery channel 6 is set below the ground so that the top of the liftable ferry device 8 can be lowered to the bottom of the translation guide rail 71. In this way, the ferry device 8 does not occupy the working space of the mold storage and retrieval machine 7. While the ferry device 8 is working, the mold storage and retrieval machine 7 can transport the mold 9 at the bottom of the first column 31 of kiln A to the bottom of the first column 41 of kiln B, that is, the work required to be performed by the mold storage and retrieval machine 7 is reduced, the waiting phenomenon is alleviated, and the transportation efficiency is improved. In addition, since the ferry device 8 can be lifted and lowered, it is convenient to move the demolded mold 9 to the ferry device 8, that is, it is convenient to load the ferry device 8.

[0093] The specific implementation methods of the present application are described below with examples.

[0094] Example 1

[0095] See also Figure 1~Figure 4 In this embodiment, a recovery guide rail 81 is provided below the translation guide rail 71, and the ferry device 8 is slidably connected to the recovery guide rail 81. The ferry device 8 can move along the recovery guide rail 81 to transport the demolded mold platform 9 to the pre-casting processing station 1.

[0096] Example 2

[0097] First, see Figure 1 to Figure 10 This embodiment takes the above-mentioned ferry device 8 as an example for explanation. The ferry device 8 includes a ferry bracket 821, a conveying roller 822, a rotating plate 83 and a clamping mechanism.

[0098] A plurality of conveying rollers 822 are rotatably mounted on the ferry bracket 821 and are electrically driven so as to convey the demoulding formwork 9 to the pre-casting treatment station 1; a power source such as a lifting cylinder 823 is connected to the bottom of the ferry bracket 821 so as to realize the lifting and lowering of the ferry device 8.

[0099] The rotating plate 83 is arranged at one end of the mold stage recovery channel 6 close to the demoulding and cleaning station 5, and the rotating plate 83 can reciprocate around its own center under the drive of a motor (not shown in the figure).

[0100] The clamping mechanism is disposed on the rotating plate 83 , and is used to receive the mold stage 9 from the demoulding and cleaning station 5 and to limit the movement of the mold stage 9 relative to the rotating plate 83 .

[0101] After the mold stage 9 completes the demolding and cleaning processes at the demolding and cleaning station 5, it can be transported to the vicinity of the rotating plate 83 by a conveying device such as a conveyor belt. After the mold stage 9 is moved onto the clamping mechanism, the rotating plate 83 is rotated 180 degrees to turn the mold stage 9 upside down toward the conveying roller 822. In this way, the cleaning liquid remaining in the mold stage 9 can be discharged during the subsequent transportation of the mold stage 9 by the conveying roller 822, thereby facilitating the reuse of the mold stage 9.

[0102] The clamping mechanism includes a U-shaped frame 841 , a clamping plate 842 , a cross bar 843 , a first connecting rod 844 , a second connecting rod 845 , a third connecting rod 846 and a return spring 847 .

[0103] A plurality of receiving rollers 8412 for contacting the bottom of the die table 9 are rotatably mounted in the U-shaped frame 841. A slider 8411 is provided on one side of the U-shaped frame 841, and a slide groove 831 matching the slider 8411 is provided on the rotating plate 83. The U-shaped frame 841 is slidably connected to the rotating plate 83.

[0104] The clamping plate 842 is parallel to the rotating plate 83 . The clamping plate 842 is used to extend into the mold table 9 and cooperate with the rotating plate 83 to clamp one side of the mold table 9 .

[0105] The middle part of the cross bar 843 passes through the clamping plate 842 and is fixedly connected to the clamping plate 842. The rotating plate 83 is provided with a strip groove 832. The cross bar 843 passes through the strip groove 832 and is fixedly connected to the middle part of the third connecting rod 846. The cross bar 843 can cross the top of the die table 9. The ferry bracket 821 has an avoidance notch 8211 for avoiding the cross bar 843 and the clamping plate 842.

[0106] The first connecting rod 844 and the clamping plate 842 are located at opposite sides of the rotating plate 83 , and one end of the first connecting rod 844 is rotatably connected to the rotating plate 83 .

[0107] The second connecting rod 845 and the clamping plate 842 are located on opposite sides of the rotating plate 83 , and one end of the second connecting rod 845 is rotatably connected to the rotating plate 83 ; the second connecting rod 845 and the first connecting rod 844 are parallel to each other.

[0108] One end of the third connecting rod 846 is rotatably connected to the first connecting rod 844 , and the other end is rotatably connected to the second connecting rod 845 ; the third connecting rod 846 is parallel to the rotating plate 83 .

[0109] One end of the return spring 847 is connected to the first connecting rod 844, and the other end is connected to the rotating plate 83. The return spring 847 has a return force that causes the first connecting rod 844 to rotate clockwise ( Figure 7 Clockwise as shown) to move the third connecting rod 846 away from the rotating plate 83, thereby driving the clamping plate 842 to contact the mold platform 9 through the cross bar 843.

[0110] like Figure 7 As shown, after the die table 9 is moved onto the plurality of receiving rollers 8412, it rotates clockwise ( Figure 7 Rotating the first connecting rod 844 (clockwise as shown) can make the third connecting rod 846 away from the rotating plate 83, and the third connecting rod 846 drives the cross bar 843, and the cross bar 843 drives the clamping plate 842, so that the clamping plate 842 extends into the die table 9 and cooperates with the rotating plate 83 to clamp one side of the die table 9. During the clockwise rotation of the first connecting rod 844, the cross bar 843 moves along the vertical plane and the horizontal plane, and maintains a horizontal state, so that the clamping plate 842 and the rotating plate 83 remain parallel. When the clamping plate 842 extends into the die table 9 and cooperates with the rotating plate 83 to clamp one side of the die table 9, the cross bar 843 can cross the top of the die table 9. In this way, through the cooperation of the cross bar 843 and the receiving roller 8412, and through the cooperation of the clamping plate 842 and the rotating plate 83, the movement of the die table 9 relative to the rotating plate 83 can be limited, thereby preventing the die table 9 from slipping during the process of rotating the die table 9 180 degrees and buckling it upside down.

[0111] like Figure 6 and 8 As shown, the ferry device 8 also includes a vertical moving mechanism. The vertical moving mechanism is connected to the clamping mechanism in a transmission manner, and is used to drive the conveying roller 822 to move down by X cm when the lifting cylinder 823 drives the clamping mechanism and the mold table 9 to rotate counterclockwise ( Figure 5 After rotating 180 degrees (counterclockwise as shown), the clamping mechanism drives the inverted mold platform 9 to move down by X cm, so that the mold platform 9 and the conveying roller 822 are in contact or close to each other, to prevent the mold platform 9 from falling on the conveying roller 822 and causing damage due to the excessive vertical distance between the mold platform 9 and the conveying roller 822 after the clamping mechanism releases the mold platform 9.

[0112] In a specific implementation scenario, the vertical moving mechanism includes an adjusting cylinder 85; the lifting cylinder 823 drives the conveying roller 822 to move down by X cm and the rotating plate 83 drives the clamping mechanism and the mold table 9 to rotate counterclockwise ( Figure 5 After rotating 180 degrees (counterclockwise as shown), the adjusting cylinder 85 drives the clamping mechanism and the inverted mold platform 9 to move down by X cm, so that the mold platform 9 contacts the conveying roller 822, to avoid the inverted mold platform 9 falling on the conveying roller 822 and causing damage due to the excessive vertical distance between the inverted mold platform 9 and the conveying roller 822 after the clamping mechanism releases the mold platform 9.

[0113] In another specific implementation scenario, the vertical moving mechanism includes a telescopic rod 861 , an iron block 862 , a tension spring 863 , an electromagnet 864 and a connecting frame 865 .

[0114] The upper end of the telescopic rod 861 is mounted on the rotating plate 83 through a supporting plate, and the lower end is a free end.

[0115] One end of the iron block 862 is connected to the lower end of the telescopic rod 861. The slider 8411 is connected to the iron block 862.

[0116] The tension spring 863 is sleeved on the telescopic rod 861, one end of the tension spring 863 is connected to the support plate, and the other end is connected to the iron block 862; the telescopic rod 861 has a shortest state and a stretched state, and the restoring force of the tension spring 863 is used to make the telescopic rod 861 in the shortest state.

[0117] The electromagnet 864 is installed on the connecting frame 865 ; when the rotating plate 83 rotates 180 degrees counterclockwise to turn the mold table 9 upside down toward the conveying roller 822 , the electromagnet 864 is located directly below the iron block 862 .

[0118] The connecting frame 865 is used to support the electromagnet 864 , and the connecting frame 865 is installed on the ferry bracket 821 .

[0119] When the conveyor roller 822 is above the ground (after the lifting cylinder 823 drives the ferry bracket 821 and the conveyor roller 822 to move upward), the telescopic rod 861 is at its shortest state and the mold table 9 is in an inverted state (the rotating plate 83 rotates 180 degrees), the top of the conveyor roller 822 is close to the mold table 9, so that the mold table 9 can be smoothly transferred to the conveyor roller 822 when the conveyor roller 822 is above the ground. Figure 5 and Fig.10 As shown, when the lifting cylinder 823 drives the conveying roller 822 and the ferry bracket 821 to move downward, the connecting frame 865 and the electromagnet 864 move downward the same distance as the ferry bracket 821, and the electromagnet 864 is energized. The iron block 862 drives the U-shaped frame 841 to move downward under the attraction of the electromagnet 864, and the U-shaped frame 841 pushes the inverted mold table 9 and the cross bar 843 downward, so that the inverted mold table 9 contacts the conveying roller 822, to prevent the inverted mold table 9 from falling on the conveying roller 822 and causing damage due to the excessive vertical distance between the inverted mold table 9 and the conveying roller 822 after the clamping mechanism releases the mold table 9. After the inverted mold table 9 is transferred to the conveying roller 822, the electromagnet 864 is powered off to restore the telescopic rod 861 to the shortest state, and the rotating plate 83 rotates in the opposite direction to move the receiving roller 8412 to the initial position ( Figure 6 The state shown in the figure) facilitates the transportation of the next mold platform 9.

[0120] The end of the mold platform recovery channel 6 close to the pre-casting treatment station 1 can be set with corresponding components referring to the above-mentioned rotating plate 83, clamping mechanism and vertical moving mechanism to flip and restore the inverted drainage mold platform 9, so as to facilitate the placement of steel cages, spraying of demoulding oil and other operations in the mold platform 9.

[0121] Second, see Figure 1 to Figure 10 This embodiment provides a method for conveying precast concrete parts, which uses the above-mentioned conveying system for precast concrete parts. The method for conveying precast concrete parts includes:

[0122] The mold platform 9 passes through the pre-casting treatment station 1, the casting station 2, the A curing kiln 3, the B curing kiln 4, the demoulding and cleaning station 5 and the mold platform recovery channel 6 in sequence, and then returns to the pre-casting treatment station 1.

[0123] The process of moving the mold table 9 from the demoulding and cleaning station 5 to the mold table recovery channel 6 includes the following steps:

[0124] Step S11, moving the flat mold platform 9 onto a plurality of receiving rollers 8412.

[0125] Step S12 : The clamping mechanism limits the movement of the mold stage 9 relative to the rotating plate 83 .

[0126] Step S13 , the rotating plate 83 rotates 180 degrees counterclockwise, and the mold table 9 is turned upside down toward the conveying roller 822 .

[0127] Step S14 : The clamping mechanism releases the mold stage 9 and transfers the mold stage 9 to the conveying roller 822 .

[0128] In step S14, if the lifting cylinder 823 drives the conveying roller 822 to move down by X cm, the clamping mechanism drives the inverted mold table 9 to move down by X cm, so that the mold table 9 contacts the conveying roller 822, to avoid the mold table 9 falling on the conveying roller 822 and causing damage due to the excessive vertical distance between the mold table 9 and the conveying roller 822 after the clamping mechanism releases the mold table 9.

[0129] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be arbitrarily combined with each other.
