DETAILED DESCRIPTION

[0044] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0046] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0047] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the utility model product is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0048] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0049] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0050] Concrete piles are generally laid by two methods: pumping and manual mold opening.

[0051] Pumped concrete placement involves a pump conveying concrete through a pipe into a closed pipe mold. This process offers high efficiency, low labor intensity, and a good on-site working environment and pile appearance. However, it requires a large concrete slump, which can lead to pipe blockage and high equipment costs.

[0052] In the manual mold opening and material distribution process, the tube mold is not closed. After the cage reinforcement is installed in the bottom mold, a fixed distribution hopper is used to complete the material distribution before the mold is closed. This process can use low-slump concrete materials, and the water-cement ratio is easy to control. However, it is labor-intensive, the working environment is poor, and concrete scattered on the joints of the tube mold is difficult to clean, making mold closing difficult and the pile appearance quality poor. As mentioned in the background technology, in the prior art, the process of distributing concrete piles requires the use of a spiral blade conveying method or a pumping method. Due to the conventional design of the spiral conveying structure and the long length of the spiral conveying structure, it is very difficult to replace the spiral conveying structure in actual production due to the limited workshop width.

[0053] In addition, the blades of the screw conveyor can adopt a shafted screw conveyor structure or a shaftless screw conveyor structure. Specifically, the spiral barrel of the screw conveyor extends entirely into the tail end of the pipe mold, forming a cantilevered stress state, which may result in large deflection. The shafted screw conveyor structure has high rigidity, and when deflected, it will cause coaxial deformation, causing structural damage to the entire equipment (primarily causing structural damage to the drive components and sealing structure used to drive the spiral blades to rotate). Although the shaftless screw conveyor structure is flexible and can adjust with the cantilever, its poor rigidity makes it easy to cause compression deformation of the shaftless screw conveyor structure when conveying concrete over long distances.

[0054] In addition, since the spiral cylinder is in a cantilever state after being extended into the pipe mold, the cage reinforcement of the spiral cylinder overlaps the pipe mold and slides along the main reinforcement. There is a problem that the sharp corners at the discharge end of the spiral cylinder are easy to scrape off the cage reinforcement.

[0055] At the same time, in the existing technology, when faced with sudden power outages or damage to the driving parts that drive the spiral blades to rotate, the large amount of residual concrete materials in the discharge chute and the spiral cylinder cannot be promptly and effectively removed, affecting the use of the distribution equipment.

[0056] In view of this, please refer to Figures 1-11 The spiral conveying structure 100, the material conveying device 1000 and the concrete pile placing equipment provided in the embodiment of the present invention can solve this problem, which will be described in detail below.

[0057] Please refer to Figure 1 and Figure 2 In an embodiment of the present invention, a concrete pile distribution equipment is provided, which includes a material conveying device 1000, a stirring device 2001, a fixing seat 2002, a concrete trough 2003, a cylinder support follower vehicle 2004, a pipe mold 2005 and a pipe mold moving vehicle 2006.

[0058] Among them, the concrete trough 2003 can be connected to the cylinder 300. The concrete trough 2003 is used to deliver the concrete or cleaning water in the mixing device 2001 into the interior of the cylinder 300. The cylinder 300 is set on the fixed seat 2002. The cylinder support follower vehicle 2004 is used to support the cylinder 300. The pipe mold moving vehicle 2006 is used to support the pipe mold 2005 and drive the pipe mold 2005 close to or away from the cylinder 300. In addition, the concrete pile placing equipment also includes a waste trough 2007 and a forklift 2008. The forklift 2008 is used to transport the waste trough 2007, and the waste trough 2007 is used to collect wastewater or waste discharged from the cylinder 300.

[0059] Specifically, the material conveying device 1000 includes a driving member 200, a cylinder 300 and a spiral conveying structure 100. The driving member 200 is connected to the spiral conveying structure 100. The driving member 200 is used to drive the spiral conveying structure 100 to rotate. The cylinder 300 is sleeved on the outside of the spiral conveying structure 100.

[0060] The spiral conveying structure 100 includes a spiral blade 20 and a shaft 10. The spiral blade 20 includes a plurality of spiral blade segments 21. The spiral blade segments 21 are connected to the shaft 10. Adjacent spiral blade segments 21 are detachably connected to divide the spiral conveying structure into a plurality of independent spiral structures.

[0061] At the same time, adjacent spiral blade segments 21 are detachable, so that the entire spiral conveying structure 100 can be divided into multiple spiral structures, which makes it easy to replace one or more spiral structures, thereby facilitating the replacement of the spiral conveying structure 100.

[0062] Please continue to refer to Figure 3 In this embodiment, the spiral blade 20 has a shaft area 101 and a shaft-free area 102 . A plurality of spiral blade segments 21 together define the shaft area 101 and the shaft-free area 102 . The shaft body 10 is disposed in the shaft area 101 .

[0063] Among them, the shaft body 10 is provided in the shaft area 101. It is easy to understand that the spiral conveying structure 100 has both a shaft spiral conveying structure and a shaftless spiral conveying structure, and has the advantages of both the shaft spiral conveying structure and the shaftless spiral conveying structure, avoiding the problem of structural damage and the problem of compression deformation of the spiral conveying structure 100.

[0064] That is to say, since the spiral conveying structure has a shaft area 101 and a shaftless area 102, wherein the shaft area 101 is provided with a shaft body 10, it is easy to understand that the spiral conveying structure has both a shaft spiral conveying structure and a shaftless spiral conveying structure, and has the advantages of both a shaft spiral conveying structure and a shaftless spiral conveying structure, thereby avoiding the problem of structural damage and the problem of compression deformation of the spiral conveying structure.

[0065] In this embodiment, the location where adjacent spiral blade segments 21 can be detachably connected is located in the shaftless area 102 , and the rotation axis of the shafted spiral conveying structure 100 can be collinear with the rotation axis of the shaftless spiral conveying structure 100 .

[0066] In addition, the entire spiral conveying structure 100 is divided into multiple spiral structures. The number of shafts 10 of the entire spiral conveying structure 100 can be multiple, and adjacent shafts 10 are distributed at intervals. Among them, some spiral structures can have shafts 10, and other spiral structures can not have shafts 10.

[0067] It should be noted that the “plurality” mentioned in this application can be understood as at least two.

[0068] It is easy to understand that a single helical structure may include both an axial helical structure portion and an axial-free helical structure portion, or may only have an axial helical structure portion, or may only have an axial-free helical structure portion.

[0069] Of course, in some embodiments, the number of the shaft body 10 may also be one. For example, the entire spiral conveying structure 100 is divided into two spiral structures, one of which has the shaft body 10 and the other does not.

[0070] Please refer to Figure 3 and Figure 4 In addition, in order to facilitate the connection of adjacent spiral blade segments 21, the spiral conveying structure 100 includes a first spiral plate 30 and a second spiral plate 40. The first spiral plate 30 is arranged at the connection of adjacent spiral blade segments 21, and the first spiral plate 30 is simultaneously adhered to and connected to the adjacent spiral blade segments 21.

[0071] The second spiral plate 40 and the first spiral plate 30 are both arranged at the same connection of adjacent spiral blade segments 21, and the second spiral plate 40 is simultaneously fitted and connected to the adjacent spiral blade segments 21, wherein the second spiral plate 40 and the first spiral plate 30 are arranged at intervals, and the first spiral plate 30, the spiral blade 20 structure at the connection of adjacent spiral blade segments 21 and the second spiral are stacked in sequence.

[0072] It is easy to understand that the first spiral plate 30 and the second spiral plate 40 both have a spiral plate structure, and the first spiral plate 30 fits the connection between adjacent spiral blade segments 21, and the second spiral plate 40 also fits the connection between adjacent spiral blade segments 21. While connecting the adjacent spiral blade segments 21, the spiral shape of the overall spiral conveying structure 100 is not destroyed, thereby avoiding affecting the concrete conveying process.

[0073] Please continue to refer to Figure 5 Specifically, the spiral conveying structure 100 also includes a fastener 50, a first protective cover 60 and a second protective cover 70. The fastener 50 passes through the first spiral plate 30, the spiral blade segment 21 and the second spiral plate 40 in sequence, wherein the fastener 50 has a first end and a second end. The first protective cover 60 is arranged on the first spiral plate 30 to cover the first end, and the second protective cover 70 is arranged on the second spiral plate 40 to cover the second end.

[0074] The fastener 50 sequentially penetrates the first spiral plate 30 , the spiral blade segment 21 and the second spiral plate 40 , so that the first spiral plate 30 and the second spiral plate 40 can clamp the structure at the connection of adjacent spiral blade segments 21 .

[0075] Alternatively, there are multiple fasteners 50, and at the connection between adjacent spiral blade segments 21, the first spiral plate 30, one of the adjacent spiral blade segments 21 and the second spiral plate 40 are penetrated by fasteners 50. At the same time, another area of ​​the first spiral plate 30, another adjacent spiral blade segment 21 and another area of ​​the second spiral plate 40 are also penetrated by fasteners 50, thereby realizing the connection of adjacent spiral blade segments 21.

[0076] It is easy to understand that the plurality of fasteners 50 may be distributed along the spiral direction of the spiral blade.

[0077] The fastener 50 can be completely enclosed by the first protective cover 60 and the second protective cover 70 to prevent the fastener 50 from contacting the concrete in the cylinder 300 , thereby ensuring the normal performance of the fastener 50 .

[0078] In this embodiment, the fastener 50 can be a bolt, and the first protective cover 60 includes a protective tube 62 and a soft rubber plug 61. The protective tube 62 is a circular cylindrical body 300 structure, and the protective tube 62 is sleeved on the outside of the bolt head of the bolt. One end of the protective tube 62 is tightly fitted on the first spiral plate 30, and the other end opening of the protective tube 62 is provided with a soft rubber plug 61 to seal the other end opening of the protective tube 62.

[0079] The end of the fastener 50 away from the bolt head extends out of the second spiral plate 40, and the second protective cover 70 includes a nut 71 and a sealing cover 72. The nut 71 is threadedly connected to the end of the fastener 50 away from the bolt head. One end of the nut 71 is connected to the second spiral plate 40 by welding, and the other end of the nut 71 is provided with a sealing cover 72 to seal the other end of the nut 71.

[0080] It should be noted that when it is necessary to disassemble adjacent spiral blade segments 21, all rubber plugs at the positions of the adjacent spiral blade segments 21 can be removed and all bolts can be unscrewed. At this time, the first spiral plate 30 and the second spiral plate 40 can be detached from the connection between the adjacent spiral blade segments 21, and the adjacent spiral blade segments 21 can be separated to realize the disassembly of multiple spiral structures of the spiral conveying structure 100.

[0081] Also, please refer again to Figure 2 The cylinder 300 is provided with a water injection port 301, which is connected to the interior of the cylinder 300, and the water injection port 301 is arranged at a position of the cylinder 300 close to the driving member 200. At the same time, the material conveying device 1000 also includes a discharge nozzle 400, which is connected to the interior of the cylinder 300, and the discharge nozzle 400 has an arc-shaped guide surface 401. The discharge nozzle 400 is arranged at one end of the cylinder 300 away from the driving member 200.

[0082] Please refer to Figure 7 and Figure 8 The cylinder 300 includes a first cylinder shell 310 and a second cylinder shell 320, and the second cylinder shell 320 can be rotatably connected to the first cylinder shell 310 to open or close the cylinder 300, wherein the discharge nozzle 400 can be set in the second cylinder shell 320, and the water injection port 301 can be set in the first cylinder shell 310.

[0083] Please refer to Figure 9 and Figure 10In addition, the first cylinder shell 310 includes multiple shell structures 311, and adjacent shell structures 311 can be detachably connected to facilitate cleaning and maintenance of the cylinder 300. Multiple shell structures 311 can be rotatably connected to the second cylinder shell 320, and the water inlet 301 can be set in one of the shell structures 311 of the first cylinder shell 310.

[0084] It should be noted that one of the shell structures 311 has a feed opening, and the feed opening of the shell structure 311 can be connected to the concrete trough to facilitate the concrete material in the concrete trough to enter the cylinder 300.

[0085] Please refer to Figure 6 The spiral conveying structure 100 also includes a transmission shaft 80, which is drive-connected to the driving member 200. At the same time, the transmission shaft is connected to the spiral blade segment 21 or the shaft body 10. In this embodiment, one end of the transmission shaft 80 can be connected to the shaft body 10, and the other end of the transmission shaft can be connected to the driving member 200.

[0086] It should be noted that, in this embodiment, the driving member 200 may be a combination structure of an existing motor and a reducer, a combination structure of a motor and a gear box, or a hydraulic motor.

[0087] In order to prevent concrete from damaging the transmission part of the material conveying device 1000, it is necessary to seal the transmission shaft end of the spiral conveying structure 100. The material conveying device 1000 also includes a sealing structure 500. The sealing structure 500 includes a mounting seat 510, a floating oil seal 520, a skeleton oil seal 530 and a bearing 540. The mounting seat 510 is sleeved on the transmission shaft 80, and the floating oil seal 520, the skeleton oil seal 530 and the bearing 540 are sequentially arranged on the mounting seat along the axial direction of the transmission shaft. The floating oil seal 520, the skeleton oil seal 530 and the bearing 540 are all surrounded by the transmission shaft 80.

[0088] In this embodiment, there are two skeleton oil seals 530 .

[0089] It should be noted that the cylinder also includes an end plate 330, which can be connected to the shell structure 311 of the first cylinder shell 310 and the second cylinder shell 320 at the same time, and the mounting seat 510 is connected to the end plate 330. At the same time, the mounting seat 510 and the cylinder can jointly define a grease gap 502. Specifically, the mounting seat 510 and the end plate 330 of the cylinder jointly define the grease gap 502, and the mounting seat 510 is provided with an oil inlet 501, which is connected to the grease gap 502. The oil inlet 501 can be connected to an automatic oil filling device (not shown) to regularly and quantitatively add grease to the sealing structure 500, so that the grease gap 502 is filled with grease, effectively isolating the concrete.

[0090] Thus, four seals are achieved, namely, grease sealing, floating oil seal 520 sealing, and two skeleton oil seals 530 (equivalent to double skeleton oil seal sealing), and the entire sealing structure 500 is stable and reliable.

[0091] Specifically, the mounting seat includes a fixing seat 511, a mounting seat body mounting plate 512, a mounting seat body 513 and a pressure cover 514, the oil inlet 501 is set on the mounting seat body 513, and the fixing seat 511, the end plate 330, the mounting seat body mounting plate 512 and the mounting seat body 513 jointly define a grease gap 502.

[0092] The end plate 330 of the cylinder 300 and the mounting seat body mounting plate 512 are fixed together by welding, and the mounting seat body 513 is fixed to the mounting seat body mounting plate 512 .

[0093] The fixed seat 511 is sleeved and installed on the transmission shaft 80 and can rotate together with the transmission shaft 80. The fixed seat 511 can be replaced after being worn, and there is no need to replace the transmission shaft 80. The floating oil seal 520 and the skeleton oil seal 530 are both sleeved on the outside of the partial structure of the fixed seat 511. The transmission shaft 80 passes through the inner space of the fixed seat 511. The bearing 540 is sleeved on the outside of the transmission shaft 80. The mounting seat body 513 is simultaneously sleeved on the outside of the floating oil seal 520, the outside of the two skeleton oil seals 530 and the outside of the bearing 540, so that the outside of the floating oil seal 520, the outside of the two skeleton oil seals 530 and the bearing 540 can be installed on the inside of the mounting seat body 513.

[0094] The pressure cover 514 is sleeved on the transmission shaft 80 . At the same time, the pressure cover 514 is arranged on a side of the mounting base 513 away from the end plate 330 . The pressure cover 514 can play a role of dustproof sealing.

[0095] In addition, the sealing structure 500 further includes a retaining ring 550 . The retaining ring 550 is sleeved on the transmission shaft 80 . The retaining ring 550 is used to abut against the bearing 540 .

[0096] Of course, in other embodiments, such as Figure 11 As shown, it is also possible that the spiral blade only has an axis area and no axis-free area, that is, the number of axis bodies is multiple, and the multiple axis bodies are connected in sequence, which is equivalent to a continuous axis. The multiple axis bodies and the multiple spiral blade segments can correspond one to one, and each spiral blade segment is connected to each axis body.

[0097] Part of the structure of one of the shaft bodies can pass through the barrel 300 and be arranged at the position of the discharge nozzle 400, where the part of the shaft body structure can come into contact with the discharge nozzle 400. The shaft body is supported on the discharge nozzle 400 to prevent the spiral blades from sagging and having no contact with the inner wall of the barrel, thereby reducing wear.

[0098] It should be noted that the concrete pile placing equipment provided in this embodiment is specifically described in terms of the placing process:

[0099] After the mold closing and tensioning is completed, the pipe mold 2005 is placed on the pipe mold mobile car 2006 (which can be understood as a mobile flat car) and then the material is laid. This can effectively avoid the mold opening and material laying process. The concrete material scattered on the joints of the pipe mold 2005 is difficult to clean, causing difficulty in mold closing, resulting in poor appearance quality of the pile and other disadvantages.

[0100] Among them, in this embodiment, the number of the cylinder support follower vehicles 2004 is multiple, among which the positions of the material conveying device 1000, the fixed seat 2002, the water injection port 301, and the concrete trough 2003 remain stationary, and the cylinder support follower vehicles 2004 can move in both directions along the length direction of the cylinder 300. When the cylinder 300 is not extended into the pipe mold 2005, the cylinder support follower vehicles 2004 are evenly distributed along the length direction of the cylinder 300 to support the cylinder 300.

[0101] When laying the material, first, the concrete material falls into the concrete trough 2003 from the stirring device 2001. A gate is provided at the bottom of the concrete trough 2003 to control the falling of the material, and the concrete material enters the interior of the cylinder 300. Afterwards, the position of the material conveying device 1000 remains unchanged, and the pipe mold moving vehicle 2006 and the pipe mold 2005 move toward the material conveying device 1000 until the cylinder 300 extends into the designated position inside the pipe mold 2005 near the tensioning end, and starts laying the material when it reaches the designated position.

[0102] Among them, the driving part 200 drives the spiral conveying structure 100 to transport concrete materials. According to the set program (including the required amount of material per meter), the pipe mold 2005 moves the flat car and the pipe mold 2005 moves in the opposite direction to automatically lay the material. The material laying is stopped after the discharge port at the end of the cylinder 300 is separated from the tail plate hole of the pipe mold 2005.

[0103] Afterwards, the pipe mold moving cart 2006 and the pipe mold 2005 move toward the material conveying device 1000. When the spiral cylinder 300 extends into a certain position of the pipe mold 2005, the moving flat cart contacts the cylinder support follower cart 2004 and pushes the cylinder support follower cart 2004 to move toward the concrete trough 2003. Among them, when the pipe mold 2005 moving flat cart and the pipe mold 2005 move in the opposite direction toward the material conveying device 1000, they will pull the cylinder support follower cart 2004 to move to the initial position.

[0104] During the cleaning process of the material conveying device 1000, water from the cleaning stirring device 2001 falls into the cylinder 300, and the driving member 200 drives the spiral conveying structure 100 to rotate forward and reverse to clean the material conveying device 1000. At the same time, high-pressure water is added to the water inlet 301 to improve the cleaning effect.

[0105] The waste water and waste materials generated during the cleaning process are transported by the material conveying device 1000 and fall into the waste trough 2007, and are transferred by the forklift 2008. There is no need to open an additional sewage pool, and the on-site working environment is effectively improved.

[0106] When the worn spiral conveying structure 100 needs to be replaced: the first cylinder shell 310 can be opened and the spiral conveying structure 100 can be split into multiple spiral structures for easy replacement, which effectively solves the problem of difficulty in replacing the spiral conveying structure 100 during production due to limited workshop width.

[0107] In the face of emergencies, such as sudden power outages, damage to the drive member 200, and a large amount of concrete remaining in the cylinder 300 and the concrete trough, the first cylinder shell 310 of the cylinder 300 can be opened, the spiral conveying structure 100 can be split into multiple spiral structures, and the split spiral structures can be removed from the cylinder 300 to clear the concrete in the cylinder 300.

[0108] At the same time, the second cylinder shell 320 of the cylinder 300 is turned downward and opened to clear the concrete material trough 2003 and the second cylinder shell 320.

[0109] In summary, the spiral conveying structure 100 provided in this embodiment has at least the following advantages:

[0110] 1. A screw conveying structure 100 combining a shafted and shaftless screw structures is used to drive concrete. The shaftless screw's flexibility allows it to adjust to the cantilever flexure of the cylinder 300, preventing structural damage. The shafted screw's increased local rigidity prevents compression deformation of the screw blades 20 during long-distance concrete transport.

[0111] 2. The spiral blade 20 has a plurality of detachable spiral blade segments 21, and the first cylinder shell 310 and the second cylinder shell 320 are rotatably connected, which can solve the problems of the long length of the spiral conveying structure 100, the limited workshop width, and the difficulty in replacing the worn spiral conveying structure 100 in actual production. At the same time, the first cylinder shell 310 can be opened to facilitate the dismantling of the spiral conveying structure 100, and solve the problems of sudden power outages, damage to driving parts, and removal of a large amount of concrete materials remaining in the spiral cylinder 300 and the discharge chute.

[0112] 3. Improve the spiral cleaning system, use the stirring device 2001 to clean the material conveying device 1000 with water, and at the same time add supplementary high-pressure water for cleaning. Use the forklift 2008 and waste trough 2007 to transfer and clean the waste water and waste. There is no need to dig a cleaning pool on site, which not only reduces the waste of cleaning water, but also improves the on-site working environment.

[0113] 4. The discharge end of the spiral cylinder 300 is designed to have a smooth arc-shaped guide surface 401, which can be smoothly overlapped on the cage reinforcement. This solves the problem that the spiral cylinder 300 is in a cantilever state after extending into the pipe mold 2005, the cylinder 300 is overlapped on the pipe mold 2005, the cage reinforcement runs along the main reinforcement, and the sharp corners of the discharge end of the spiral cylinder 300 are easy to scrape off the cage reinforcement.

[0114] 5. Compared with the pumping material distribution process: the structure is simple, which reduces the high standards and high requirements for concrete materials, and at the same time has the advantages of high efficiency and low cost.

[0115] 6. Compared with the mold-opening fabric process: it improves the working environment, reduces labor intensity, and improves the appearance quality.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
