Description

Technical Field

[0001] This invention relates to the field of aerated concrete production technology, specifically to a method for operating a heavy-duty AGV conveyor mold vehicle used in aerated concrete production. Background Technology

[0002] The common mold transport process in aerated concrete production lines is as follows: the mold cart travels linearly on ground tracks via friction wheels or a chain traction mechanism. If turning is required, a shuttle car is used for transport. Traditionally, shuttle cars on aerated concrete production lines are guided by tracks, and the carts move along these tracks.

[0003] AGV (Automated Guided Vehicle) conveying technology is widely used in other industries because it can set its own travel path, saving more space and time compared to rail-based movement. Currently, AGV conveyors are rarely used in aerated concrete production lines.

[0004] Existing shuttle vehicles used to carry mold carts mostly simply place them on a surface and then operate at low speeds, as described in CN201020223826.1. Therefore, they lack effective restraint for the mold carts. Although some patents employ limit rod structures to block the mold carts, they lack sufficient clearance to avoid interfering with the transfer of the mold carts.

[0005] Regarding the production process of aerated concrete, reference CN202211121768.5 describes a production process for aerated concrete panels, including injecting material into a mold from a casting mixer, oiling the inner surface of the mold, inserting guide rods, curing in a static chamber, removing the guide rods, flipping the mold to separate the preform from the mold, and cutting. Flipping and demolding often employs a fully automatic flipping and demolding lifting device similar to that described in CN201210535364.0 for aerated concrete production lines. However, when using a lifting device for flipping, precise transfer is required, and it must be ensured that the side plates of the mold carriage align with the lower track during flipping. Flipping can cause the aerated concrete to detach from the side plates due to inertia, leading to a side overturn. Summary of the Invention

[0006] This invention provides a method for operating a heavy-duty AGV conveying mold vehicle for aerated concrete production, in order to solve the technical problem that existing shuttle vehicles can only move along fixed tracks and cannot effectively limit movement, resulting in a slow production cycle.

[0007] This invention includes:

[0008] A method for operating a heavy-duty AGV conveyor mold vehicle for aerated concrete production further includes the following steps:

[0009] Step 1: The AGV conveyor car stops the oiled mold car in the pouring position to complete the pouring and unloading.

[0010] Step 2: The AGV conveyor moves the casting mold car to the insertion position to complete the insertion of the pin in the mold car.

[0011] Step 3: The AGV transport vehicle moves the mold car with the insert rod to the stationary stop chamber and places the transported mold car into one end of the track in the stationary stop chamber.

[0012] Then, the AGV transport vehicle moves to the other end of the track in the static parking chamber and transports the mold car that has been maintained onto the AGV transport vehicle.

[0013] Step 4: The AGV transport vehicle moves the mold car to the chisel removal and car change position, unloads the mold car, and completes the chisel removal and car change actions.

[0014] An empty AGV transport vehicle moves to the oiling and changing position, and then carries a new oiling mold vehicle to the pouring position, where it begins to wait for pouring and unloading in step 1.

[0015] Step 5: In step 4, the AGV transport vehicle 2 transports the mold car after the chisel has been removed to the empty flip demolding position to achieve mold demolding;

[0016] Step 6: The empty AGV transport vehicle 2 is transported to the empty mold position, carries the new mold car, and is transported to the oiling position for oiling inside the mold car;

[0017] Step 7: AGV transport vehicle 2 transports the oiled mold car to vehicle exchange position 2; unloads the oiled mold car, moves the empty car to the chisel removal vehicle exchange position, and then proceeds to step 5 to transport the chisel-removed mold car again.

[0018] In a further technical solution, an AGV transport vehicle and a mold vehicle are included, wherein a set of side plates of the mold vehicle are movably connected.

[0019] The AGV transport vehicle includes a main frame, on which a mold vehicle is mounted;

[0020] The main frame is equipped with a stop structure and a rolling structure. The mold carriage is mounted on the rolling structure, and the rolling structure is attached to the bottom of the mold carriage. The stop structure is used to restrict the mold carriage on the upper surface of the main frame.

[0021] The main frame houses a power module and a drive structure, with wheels mounted at the bottom; the drive structure is used to drive the wheels to move and steer.

[0022] In a further technical solution, the rolling structure includes a top roller, and an installation cavity is provided at the bottom of the main frame. A fixing plate is installed in the installation cavity. Multiple sets of fixing plates are provided, and two fixing plates are symmetrically distributed in each set and connected to the top roller by a mounting connecting shaft.

[0024] In a further technical solution, the stopping structure includes a stopping electric cylinder, and a position hole is opened on the main frame, with a position sensor fixedly installed on the surface;

[0025] A stop cylinder is installed in the position hole, with the output end of the stop cylinder facing upwards; a stop pin is installed on the output end of the stop cylinder via a coupling, and the diameter of the stop pin is smaller than the inner diameter of the position hole.

[0026] The stop posts are provided in multiple sets and distributed on the outside of the mold car.

[0027] In a further technical solution, the stop post includes a connecting part and a working part. The connecting part is connected to the output end of the stop electric cylinder via a coupling. A connecting bearing is installed between the connecting part and the working part. The connecting part is fixedly connected to the inner ring of the connecting bearing, and the outer ring of the connecting bearing is fixedly connected to the working part.

[0028] The working part is provided with a steering column, which rotates on the working part; a steering cylinder is installed in the position hole, and a steering groove is opened in the steering cylinder, and the steering column is inserted into the steering groove;

[0029] In a further technical solution, multiple sets of stop posts are distributed along the three outer edges of a rectangle; when the mold car is detached from the main frame, the stop posts move into the position holes, and the top height is not higher than the top height of the position holes.

[0030] In a further technical solution, the top of the steering column also includes a pressure plate, and a position lateral cavity is provided outside the position hole, with the pressure plate adapted to the position lateral cavity;

[0031] A flat slide is provided on the outside of the mold carriage. The steering column is used to rise along the steering groove to make a position hole, and then drive the pressure plate to abut against the flat slide.

[0032] In a further technical solution, the steering groove includes a curved portion and a lower extension portion, which are integrally formed.

[0033] In a further technical solution, a tilting trolley is installed at the empty-flipping demolding position in step 5;

[0034] The tipping vehicle includes a ring-shaped assembly and a bottom frame. The ring-shaped assembly includes an outer ring shell and an inner ring. The outer ring shell is fixedly connected to the bottom frame, and the inner ring rotates coaxially with respect to the outer ring shell.

[0035] A partition plate is installed inside the inner ring, and an abutment wheel is installed at the end of the partition plate; three sets of partition plates are provided, and adjacent partition plates are used to install AGV transport vehicle two and AGV transport vehicle three respectively; AGV transport vehicle three is transported to the inner ring in advance, and then AGV transport vehicle two is moved to the inner ring;

[0036] After the mold car is removed from the AGV transport vehicle 2, it rotates 90° with the inner ring, flipping the mold car and demolding it.

[0037] In a further technical solution, the tilting vehicle is provided with an installation area and a reduction motor is installed inside. A drive gear is installed at the output end of the reduction motor, and a toothed profile is provided outside the inner ring. The drive gear meshes with the toothed profile.

[0038] A support section is provided between adjacent partition plates. When the support section rotates to the bottom, its horizontal height matches the bottom height of the mold carriage.

[0039] A side plate and a centering push cylinder are installed on one side of the inner ring. The cylinder body of the centering push cylinder is fixedly connected to the side plate, and a push plate is installed at the output end. The push plate is used to push the flipped side plate and blocks or plates to the middle of the AGV conveyor vehicle.

[0040] Compared with existing known technologies, the technical solution provided by this invention has the following significant advantages:

[0041] This embodiment utilizes a heavy-duty AGV (Automated Guided Vehicle) to transport molds for the production of aerated concrete. A drive structure enables the movement and steering of the transport vehicle, while a stop structure restricts its movement. Top rollers facilitate the easy detachment of the molds from the AGV or their mounting onto the AGV. This invention, by incorporating an AGV transport vehicle, eliminates the need for shuttle vehicles operating along fixed tracks, improving the efficiency of mold transport, reducing equipment investment, minimizing infrastructure costs, and shortening the production line construction period.

[0042] This invention uses a stop cylinder to push the stop column forward and rotate along the steering groove, thereby achieving a 90° rotation and upward lifting of the pressure plate, followed by downward pressing onto the mold carriage, thus completing the effect of confining the mold carriage.

[0043] The drive gear and inner ring inside the tilting machine of this invention mesh and rotate, controlling the output time of the reduction motor, thereby realizing the reverse rotation when entering the AGV conveyor vehicle three; when entering the AGV conveyor vehicle two and the mold vehicle, it rotates 90° forward to complete the tilting of the mold vehicle. The reduction motor ensures that the tilting is not too large, and this invention is set to drive the mold vehicle to tilt at a low speed, and the downward drop generates vibration, achieving a rapid demolding effect.

[0044] The present invention has an anti-tipping baffle and a vertical electric cylinder installed at the top. The vertical electric cylinder can drive the anti-tipping baffle to descend downward to prevent the mold carriage from rotating and tipping over. The bottom of the anti-tipping baffle is provided with a hook and the top is provided with a lateral cylinder, which is used to move laterally to hook the mold carriage after it is overturned, so that other parts and side plates of the mold carriage are detached.

[0075] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0076] The existing aerated concrete production process includes slurry preparation, precast steel mesh, batching and pouring, inserting rods, curing, removing rods, air turning and demolding, cutting, autoclaving, breaking apart and packaging.

[0077] Example 1

[0078] like Figure 1-8 As shown, this is one embodiment of the present invention. A heavy-duty AGV conveying mold vehicle for aerated concrete production includes an AGV conveying vehicle and a mold vehicle 100. A set of side plates 101 of the mold vehicle 100 are movably connected. In this embodiment, the mold vehicle 100 can refer to the existing structure. The side plates can be flipped at the demolding position and the aerated concrete is placed on the side plates. Then, the aerated concrete is driven to carry out subsequent processes.

[0079] like Figure 1 and 4 As shown, the AGV transport vehicle includes a main frame 1, on which a mold vehicle 100 is mounted;

[0080] A stop structure 2 and a rolling structure 3 are respectively installed on the main frame 1. The mold carriage 100 is used to be installed on the rolling structure 3, and the rolling structure 3 is attached to the bottom of the mold carriage 100. The stop structure 2 is used to restrict the mold carriage 100 on the upper surface of the main frame 1.

[0081] like Figure 4 As shown, the main frame 1 is equipped with a power module 4 and a drive structure 5, and a walking wheel 51 is installed at the bottom; the drive structure 5 is used to drive the walking wheel 51 to move and steer.

[0082] like Figure 1 As shown, the rolling structure 3 includes a top roller 31, and a mounting cavity is provided at the bottom of the main frame 1, as shown. Figure 3 As shown, a fixing plate 32 is installed inside the mounting cavity; multiple sets of fixing plates 32 are provided, and two fixing plates 32 are symmetrically distributed in each set and connected to the top roller 31 by a mounting connecting shaft; combined with Figure 2As shown, in this embodiment, the top rollers 31 are provided with five sets, and three sets of connecting shafts are provided. The length of the connecting shafts may not be unique, but a feeding motor must be installed at the shaft end of one set of connecting shafts. The feeding motor is used to drive a set of top rollers to drive the loading or unloading of the mold carriage.

[0083] like Figure 2 As shown, an opening slot 11 is provided on the main frame 1, and the top of the top roller 31 extends out of the opening slot 11.

[0084] The stop structure 2 includes a stop electric cylinder 21. A position hole 12 is provided on the main frame 1, and a position sensor 13 is fixedly installed on the surface. The stop electric cylinder 21 is installed in the position hole 12, and the output end of the stop electric cylinder 21 faces upward. A stop post 23 is installed on the output end of the stop electric cylinder 21 through a coupling 22. The diameter of the stop post 23 is smaller than the inner diameter of the position hole 12. Multiple sets of stop posts 23 are provided and distributed on the outside of the mold carriage 100.

[0085] like Figure 4 and 5 As shown, the drive structure includes a front-mounted steering wheel system and a rear-mounted drive wheel system. The front-mounted steering wheel system includes a steering shaft 52, a steering gear 53, an electronic control unit 54, a steering tie rod 55, and a steering knuckle 56. The steering knuckle 56 is plate-shaped and its middle part is fixedly connected to the central axis of the travel wheel. One end of the steering tie rod 55 is hinged to the steering knuckle 56, and the other end is fixedly connected to the steering gear 53.

[0086] A gear is installed at the end of the steering shaft 52, and a rack is installed inside the steering gear 53. The gear meshes with the rack, and the rack is coaxial with the steering tie rod 55. The electronic control element controls the rotation direction and angle of the steering shaft 52. By controlling the number of rotations of the end of the steering shaft 52 inside the steering gear 53, the steering tie rod 55 outside the steering gear 53 is controlled, thereby driving the angle of the two sets of travel wheels.

[0087] like Figure 4 As shown, located Figure 4 The upper part of the rear drive wheel system includes a rear motor, a long shaft, and walking wheels installed at both ends. A bevel gear one is installed on the long shaft, and a bevel gear two is installed at the output end of the rear motor. The bevel gear one and bevel gear two mesh with each other, that is, the rear motor drives the long shaft to rotate, thereby driving the walking wheels at both ends to roll.

[0088] This embodiment utilizes a heavy-duty AGV (Automated Guided Vehicle) to transport molds for the production of aerated concrete. A drive structure enables the movement and steering of the transport vehicle, while a stop structure restricts its movement. Top rollers facilitate the easy detachment of the molds from the AGV or their mounting onto the AGV. This invention, by incorporating an AGV transport vehicle, eliminates the need for shuttle vehicles operating along fixed tracks, improving the efficiency of mold transport, reducing equipment investment, minimizing infrastructure costs, and shortening the production line construction period.

[0089] Example 2

[0090] like Figure 9-15 As shown, another embodiment of the present invention is proposed. Based on embodiment 1, the stop structure is further modified to be able to turn and press against the mold carriage, so as to reduce the number of stop structures and effectively limit the vertical movement of the mold carriage.

[0091] like Figure 9 The diagram shows a structural view of the stop post 23; the stop post 23 includes a connecting part 231 and a working part 232, as shown. Figure 15 As shown, the connecting part 231 is connected to the output end of the stop electric cylinder 21 through a coupling 22; a connecting bearing 26 is installed between the connecting part 231 and the working part 232, the connecting part 231 is fixedly connected to the inner ring of the connecting bearing 26, and the outer ring of the connecting bearing 26 is fixedly connected to the working part 232.

[0092] A steering column 233 is provided on the working part 232 and rotates on the working part 232. A steering cylinder 24 is installed in the position hole 12, and a steering groove 241 is formed in the steering cylinder 24. The steering column 233 is inserted into the steering groove 241. The steering groove 241 includes a curved part 2411 and a lower extension 2412, which are integrally formed. The top of the steering column 233 also includes a pressure plate part 234. A position lateral cavity 14 is provided outside the position hole 12, and the pressure plate part 234 is adapted to the position lateral cavity 14. A flat slide plate 101 is provided on the outside of the mold carriage 100. After the steering column 233 rises out of the position hole 12 along the steering groove 241, it drives the pressure plate part 234 to abut against the flat slide plate 101.

[0093] When the output end of the stop cylinder moves upward, the steering column abuts against the top of the curved groove. Upon abutting, it rolls upward along the top of the curved groove. Because the end of the steering column is connected to the working part, the working part is driven to rotate along the curved groove until it reaches the lower extension to complete a 90° turn and upward lifting. Then, the output end of the stop cylinder moves downward, causing the pressure plate 234 to abut against the flat trailer 101. The action command of the stop cylinder is controlled by a controller installed in the main frame 1 or a control center set up outside the factory, through a communication module to control the direction, distance, and speed of each AGV transport vehicle.

[0094] like Figure 12 As shown, multiple sets of stop posts 23 are distributed along the three outer edges of the rectangle; when the mold carriage 100 is separated from the main frame 1, the stop posts 23 move into the position hole 12, and the top height is not higher than the top height of the position hole 12.

[0095] Example 3

[0096] See Figure 16 and 17 As shown, this is one embodiment of the present invention, a method for operating a heavy-duty AGV conveying mold vehicle for aerated concrete production, which further includes the following steps:

[0097] Step 1: In the pouring position 10, the AGV conveyor 200 drives the oiled mold 100 to a stop, wait 60-80 seconds, and then complete the pouring and unloading.

[0098] Step 2: The AGV conveyor 200 drives the casting mold 100 to the insertion position 20 to complete the insertion of the pin in the mold 100.

[0099] Step 3: The AGV transport vehicle 200 drives the mold car 100 with the insert rod to the stationary stop chamber 30 and places the transported mold car 100 into one end of the track in the stationary stop chamber 30.

[0100] The AGV transport vehicle 1200 then moves to the other end of the track in the static parking chamber 30, and transports the mold vehicle 100, which has been maintained, onto the AGV transport vehicle 1200.

[0101] Step 4: AGV transport vehicle 200 drives mold vehicle 100 to the chisel removal and vehicle change position 40, unloads mold vehicle 100, and completes the chisel removal and vehicle change actions;

[0102] The AGV transport vehicle 1200 moves empty to the oiling and changing position 50, and then carries the new oiling mold vehicle 100 to the pouring position 10, and begins to wait for pouring in step 1.

[0103] Step 5: In step 4, the AGV transport vehicle 300 transports the mold car 100 after the pin is removed to the empty flip demolding position 60 to achieve mold demolding;

[0104] Step 6: The empty AGV transport vehicle 300 transports the new mold vehicle 100 to the empty mold position 70, and then transports it to the oiling position 80 to apply oil to the inside of the mold vehicle 100. The time is about 60 seconds.

[0105] Step 7: AGV transport vehicle 2 300 transports the oiled mold vehicle 100 to the changing position 2 90; unload the oiled mold vehicle 100, move the empty vehicle to the chisel removal changing position 40, and then proceed to step 5 to transport the chisel-removed mold vehicle 100 again.

[0106] In this embodiment, the quiet room has a non-U-shaped structure, such as... Figure 16 As shown. Advantages: Independent static stop position allows for first-in, last-out operation, making mold entry and exit more convenient; static stop position eliminates the need for friction wheels, reducing equipment investment; equipment maintenance is convenient.

[0107] The specific production of aerated concrete, combined with the above-mentioned operating methods, should also include cutting, autoclaving, breaking down and packaging processes. AGV transport vehicles can continue to be used to carry aerated concrete for continued production.

[0108] Example 4

[0109] like Figure 18 As shown, this is another embodiment of the present invention. In this embodiment, the curing chamber is changed from a non-I-shaped structure to a tunnel-type structure. This addresses the disadvantages of the non-I-shaped curing chamber, including the relatively small number of static parking spaces, the high operating frequency of the shuttle car, and the relatively long running time of the long-distance mold position.

[0110] The curing chamber, with its tunnel-like structure, offers relatively high speed and a relatively large number of static resting positions, enabling large-scale production of aerated concrete.

[0111] Example 5

[0112] like Figure 19-21 As shown, another embodiment of the present invention is provided. Based on embodiment 3, a tilting vehicle 6 is installed at the tilting demolding position 60 in step 5.

[0113] like Figure 20 As shown, the tipping vehicle 6 includes an annular assembly and a bottom frame 61. The annular assembly includes an outer annular shell 62 and an inner ring 63. The outer annular shell 62 is fixedly connected to the bottom frame 61, and the inner ring 63 rotates coaxially with respect to the outer annular shell 62.

[0114] A partition plate 64 is installed inside the inner ring 63, and an abutment wheel 611 is installed at the end of the partition plate 64; three sets of partition plates 64 are provided, and adjacent partition plates 64 are respectively used to install AGV transport vehicle 2 300 and AGV transport vehicle 3 400.

[0115] like Figure 19As shown, the upper left image represents the normal state; the upper right image shows the AGV transport vehicle 3 (400) pre-transported into the inner ring 63 and rotated 90° in the opposite direction; the lower right image shows the mold vehicle 100 (after the AGV transport vehicle 2 (300) has had its chisel removed) moved to the inner ring 63; the lower left image shows the tilting machine driving the mold vehicle to rotate 90° clockwise, tilting the mold vehicle 100 and demolding it. In this embodiment, the mold vehicle is tilted and demolded within the tilting vehicle, positioned in the empty tilting demolding position. First, the height of the supporting part is limited as follows... Figure 20 As shown, AGV conveyor 2 (300) and AGV conveyor 3 (400) can normally enter the tilting machine. The drive gear and inner ring inside the tilting machine mesh and rotate, controlling the output time of the reduction motor, thereby realizing the entry of AGV conveyor 3 (400) and reverse rotation; after entering AGV conveyor 2 (300) and the mold car, it rotates 90° forward to complete the tilting of the mold car. The reduction motor ensures that the tilting is not too large, and the present invention is set to drive the mold car to tilt at a low speed, and the downward drop generates vibration, achieving a rapid demolding effect.

[0116] The present invention has an anti-tipping baffle and a vertical electric cylinder installed at the top. The vertical electric cylinder can drive the anti-tipping baffle to descend downward to prevent the mold carriage from rotating and tipping over. The bottom of the anti-tipping baffle is provided with a hook and the top is provided with a lateral cylinder, which is used to move laterally to hook the mold carriage after it is overturned, so that other parts and side plates of the mold carriage are detached.

[0117] like Figure 20 As shown, the tilting vehicle 6 has an installation area and a reduction motor 65 installed inside. The output end of the reduction motor 65 is equipped with a drive gear 66. The inner ring 63 has a toothed shape on the outside, and the drive gear 66 meshes with the toothed shape. A support part 67 is provided between adjacent partition plates 64. When the support part 67 rotates to the bottom, its horizontal height is adapted to the bottom height of the mold vehicle 100.

[0118] A side plate 68 and a centering push cylinder 69 are installed on one side of the inner ring 63. The cylinder body of the centering push cylinder 69 is fixedly connected to the side plate 68, and a push plate 610 is installed at the output end.
