Description

Technical Field

[0001] The invention belongs to the technical field of building material production, and particularly relates to a concrete bridge deck co-linear production line and a production method. Background Art

[0002] At present, the research in the field of highway bridge deck prefabrication production line is relatively mature, and there are mainly the following methods.

[0003] (1) Fixed pedestal method: All processes are completed on a fixed pedestal, including mold erection, steel bar mold insertion, pouring, curing, demoulding and other processes. It is suitable for bridge deck components with larger size and heavier weight. The disadvantages are large floor space, high energy consumption, large template investment and low productivity. However, the requirements for the uniform size and specifications of bridge deck components are not high, and various components with small quantities but diverse specifications can be produced.

[0004] (2) Assembly line production method: The bottom template is sequentially transferred between each process. Generally, an independent steam curing room is set up to steam cure the components, which can reduce the curing time and has high productivity. It is suitable for smaller bridge deck components. Because the assembly line production of components has obvious advantages, with the development of technology, there is an increasing trend of using the assembly line method for bridge deck components.

[0005] However, the traditional pipeline method also has the following disadvantages:

[0006] (1) The traditional assembly line method is inefficient when the bridge deck components have various specifications and the number of each specification is small. When the materials of the bridge deck components are different, that is, there are two types of bridge deck components, ultra-high performance concrete and ordinary concrete, two traditional assembly lines are required for production, which requires large investment and poor economic efficiency.

[0007] (2) In addition, traditional production lines generally use channel-type curing kilns, and the curing temperature cannot be completely carried out according to the optimal curing temperature curve; or single-layer flat kilns are used, which can achieve curing according to the optimal curing temperature curve, but only one piece can be cured at a time, and the curing efficiency is low.

[0008] (3) At present, the curing kiln of traditional assembly lines is generally indoors, while the demoulding station is outdoors, which is poor in economy and working conditions.

[0009] Based on the above shortcomings, it is urgent to improve the traditional assembly line. Summary of the invention

DETAILED DESCRIPTION

[0086] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0087] A concrete bridge deck co-line production line, such as Figure 1 As shown, the production line is a ring production line, which includes a common prefabrication area 1, a steam curing area 2 and a transport vehicle 3. The common prefabrication area 1 is adjacent to the steam curing area 2 and is used to prefabricate different types of concrete bridge panels; the steam curing area 2 is provided with several areas, each area is used to cure different types of concrete bridge panels; the transport vehicle 3 is provided on the transport channel between the common prefabrication area 1 and the steam curing area 2, and is used to transport the prefabricated concrete bridge panels and the cured concrete bridge panels. The common prefabrication area 1 includes a mixing station, a pouring station, a stacking station, a destacking station, a demoulding station 17, a traverse station 14 and a finished product transport channel 18.

[0088] Combination Figure 2 It can be seen that the mixing station is connected to the pouring station, which can mix concrete and transport it to the pouring station. The pouring station is connected to the stacking station, which is used to pour concrete into the mobile bottom mold 15 to obtain a concrete bridge deck and transport it to the stacking station. The stacking station is adjacent to the steam curing area 2 and is located on one side of the transport vehicle 3. It is used to stack the mobile bottom mold 15 containing n layers of concrete bridge decks, n≥1. The steam curing area 2 is used to cure the concrete bridge deck in the mobile bottom form 15; the transport vehicle 3 is used to transport the mobile bottom form 15 containing the concrete bridge deck from the stacking station to the steam curing area 2 or to transport the mobile bottom form 15 and the cured concrete bridge deck to the demolding station 17; the destacking station is adjacent to the steam curing area 2 and is located on the other side of the transport vehicle 3, and is used to destacking the mobile bottom form 15 containing the concrete bridge deck after curing; the demolding station 17 is connected to the destacking station and is used to demold the mobile bottom form 15 containing the concrete bridge deck; the transverse movement station 14 is connected to the demolding station 17 and is used to transport the demolded mobile bottom form 15 to the casting station; the finished product transportation channel 18 is located on one side of the demolding station 17 and is used to transport the demolded concrete bridge deck.

[0089] It should be noted that Figure 1 and Figure 2 The steam curing area 2 of the production line is equipped with multiple areas, each of which can cure different concrete bridge decks. Therefore, the production line can be used as a common production line for various types of concrete bridge decks, enhancing the adaptability of the production line to irregular bridge deck components and improving economy.

[0090] Further, in Figure 2 The middle mixing station includes a concrete transport vehicle channel 11, a mixer 12 and a torpedo tank 13. The concrete transport vehicle channel 11 and the mixer 12 are respectively located on both sides of the torpedo tank 13, specifically, the concrete transport vehicle channel 11 is located on the outside, and the mixer 12 is located on the inside. The mixer 12 can be used to mix concrete and discharge the concrete into the torpedo tank 13. The torpedo tank 13 is located above the pouring station and can pour concrete into the mobile bottom mold 15 on the pouring station.

[0091] It should be noted that Figure 2 The mixer 12 is provided with a rotating guide chute to improve the mixing efficiency. The torpedo tank 13 adopts a lifting structure. During operation, first, the concrete transport vehicle transports the concrete to the mixing station through the concrete transport vehicle channel 11. The mixer 12 is located inside the torpedo tank 13, receives the concrete from the concrete transport vehicle and mixes it. After the mixing is completed, the mixer 12 discharges the concrete into the torpedo tank 13. The torpedo tank 13 is located above the pouring station, and its function is to store the mixed concrete and pour the concrete into the mobile bottom mold 15 on the pouring station in a timely manner to complete the concrete pouring process.

[0092] like Figure 3 As shown, the mixer 12 includes a barrel 1201, a closing plate 1202, a chute 1205 and a drive 1208. Figure 4 It can be seen that a discharge port 1209 is provided on the bottom surface of the cylinder 1201, and two supports are provided on the circumferential surface of the cylinder 1201. A rotating shaft 1204 is installed at the center of the closing plate 1202, and the rotating shaft 1204 is rotatably connected to a support on the cylinder 1201, and the upper surface of the closing plate 1202 is in contact with the bottom surface of the cylinder 1201; one end of the driver 1208 is rotatably connected to another support on the cylinder 1201, and the other end is rotatably connected to the offset shaft on the closing plate 1202, and the offset shaft is located on one side of the rotating shaft 1204. In addition, a material guide port 1203 is provided on the surface of the closing plate 1202, and when the closing plate 1202 rotates with the rotating shaft 1204, the material guide port 1203 can be made to correspond to the discharge port 1209.

[0093] The chute 1205 is fixedly installed below the closing plate 1202, and the position of the inlet corresponds to the discharge port 1209. In addition, a first stop pin 1206 and a second stop pin 1207 are installed on the upper surface of the closing plate 1202, and the first stop pin 1206 and the second stop pin 1207 are respectively located on both sides of the offset shaft and at the edge of the closing plate 1202.

[0094] It should be noted that during the production process, concrete can be stirred in the cylinder 1201, and at this time, the guide port 1203 of the closing plate 1202 deviates from the discharge port 1209 to prevent the concrete from flowing out. When the concrete is stirred, the driver 1208 controls the closing plate 1202 to rotate so that the guide port 1203 corresponds to the discharge port 1209, and then the concrete flows through the guide port 1203 to the chute 1205, and finally flows to the torpedo tank 13.

[0095] Furthermore, the flow bottom mold 15 includes a stacking type and a widened type.

[0096] like Figure 5 As shown, the stacking type flow bottom mold 15 includes a mold platform 1501, a stacking column 1502 and a guide cone shaft 1503. There are six stacking columns 1502, which are symmetrically installed on the side surface of the mold platform 1501 by welding. Specifically, three stacking columns 1502 can be welded on both sides of the mold platform 1501, and the three stacking columns 1502 are respectively located at the two ends and the middle of the mold platform 1501. The guide cone shaft 1503 is integrally arranged on the top of the stacking column 1502, and a bearing platform 1505 is welded at the bottom of the guide cone shaft 1503, and the bearing platform 1505 can bear the flow bottom mold 15 after stacking. A guide cone hole 1504 is opened at the bottom of the stacking column 1502, and the size of the guide cone hole 1504 is adapted to the guide cone shaft 1503; when stacking, the guide cone shafts 1503 of the adjacent layers are embedded in the guide cone hole 1504.

[0097] In addition, Figure 6 As shown, in order to improve the stability between the mold platform 1501 and the stacking column 1502, a connecting bolt 1506 can be installed between the two.

[0098] It should be noted that the stacking type flow bottom mold 15 can be stacked layer by layer. Specifically, the stacking process depends on the design of the stacking column 1502 and the guide cone shaft 1503. The top of the stacking column 1502 of each flow bottom mold 15 is provided with a guide cone shaft 1503, and the bottom is provided with a guide cone hole 1504. When stacking, the guide cone shaft 1503 of the upper layer of the flow bottom mold 15 can be accurately embedded in the guide cone hole 1504 of the lower layer of the flow bottom mold 15, thereby achieving a close connection and stable stacking between layers. This structural design not only ensures the stability and safety of the flow bottom mold 15 during the stacking process, but also greatly improves the efficiency of storage and transportation.

[0099] like Figure 7 The widened flow bottom mold 15 includes a mold base 1501 and a widened bottom mold 1507, wherein the widened bottom mold 1507 is fixedly mounted on both sides of the mold base 1501. Figure 6The stacking columns 1502 in the middle make it impossible to perform stacking, and the structure is generally single-layer.

[0100] like Figure 8 As shown, a palletizer 16 is provided at both the palletizing station and the depalletizing station. The palletizer 16 has a bent support leg 1601 and a jack 1602. Under normal circumstances, when producing components of normal size, multi-layer palletizing is required. At this time, the jack 1602 needs to be installed and bears most of the weight of the operation of the palletizer 16. Fig. 9 As shown, when producing super-large components, only single-layer passing, and no stacking, the jack 1602 is removed, the lifting type stacker 16 does not work, and the bent support legs 1601 bear the weight of the stacker 16 itself.

[0101] It should be noted that there are two palletizers 16, one for palletizing and one for unpalletizing, which are respectively placed on both sides of the transport vehicle 3.

[0102] Furthermore, the production line also includes a factory building 19, the common prefabrication area 1 is located in the factory building 19, and the steam curing area 2 is located outside the factory building 19. The steam curing area 2 includes a first curing area 21, a second curing area 22, a third curing area 23 and a fourth curing area 24; wherein the first curing area 21 is adjacent to the second curing area 22; the third curing area 23 is adjacent to the fourth curing area 24; and a passage for the transport vehicle 3 to operate is provided between the first curing area 21 and the third curing area 23, and between the second curing area 22 and the fourth curing area 24.

[0103] It should be noted that if Fig.10 As shown, the left side is the first curing area 21, and the right side is the third curing area 23 intermediate transport vehicle 3. In the first curing area 21, the mobile bottom mold 15 containing the stacked concrete bridge deck is placed, and in the third curing area 23, the widened mobile bottom mold 15 containing the concrete bridge deck is placed.

[0104] It should be further explained that the first curing area 21 is a multi-layer and multi-row ultra-high performance concrete component curing area, the second curing area 22 is a multi-layer and multi-row ordinary concrete component curing area, the third curing area 23 is a single-layer and single-row super-large component shared curing area, and the fourth curing area 24 is a multi-layer and single-row shared curing area.
