Description

Technical Field

[0001] This utility model belongs to the field of aerated concrete panel production technology, and more specifically, relates to an automatic replacement mechanism and replacement device for aerated concrete panel splitting clamps. Background Technology

[0002] In the field of autoclaved aerated concrete (AAC) production, AAC blocks are porous concrete products made from siliceous materials (such as yellow sand) and calcareous materials (lime and cement) through processes such as batching, mixing, pouring, curing, cutting, and autoclaving. AAC slabs, on the other hand, are porous concrete products formed by pre-inserting a steel mesh cage of a certain size within AAC blocks. However, during the production of AAC blocks or slabs, the siliceous and calcareous materials undergo a hydration reaction during high-temperature autoclaving, causing the blocks or slabs to stick together. Therefore, it is necessary to separate the finished blocks and slabs.

[0003] In traditional autoclaved aerated concrete (AAC) block production lines, the finished blocks are typically split after curing, a process known as "dry splitting." However, dry splitting requires significant force to separate the blocks due to the strong adhesion between them, easily damaging the finished products, especially thin and long blocks. Another method is to split the semi-finished blocks before curing, known as "wet splitting." Wet splitting, because it involves splitting semi-finished products without high-temperature hydration, results in weaker adhesion, making it suitable for splitting, particularly thin and long blocks. However, the replacement of the splitting clamps in existing splitting equipment is usually manual, which is labor-intensive and inefficient. Therefore, designing a device that can automatically change the splitting clamps is of significant practical importance in production.

[0004] A search revealed that patent CN114083667A discloses a splitting machine and its splitting method capable of splitting multiple layers. This application utilizes multiple sets of frames arranged at different heights on a frame, with lifting power and clamping components connecting adjacent sets of frames. The clamping components hold the billet at different heights, and the lifting power drives the frames to change height, thus separating the bonded billets into layers at different heights. This achieves simultaneous splitting of multiple layers of billets, reducing splitting time and improving the efficiency of billet splitting.

[0005] For example, patent CN112549262A discloses a wet breaking machine for aerated concrete blocks or panels. This application, through a horizontal drive device, an upper breaking device, a lower breaking device, and a lifting device, can break horizontally stacked blanks. This avoids the problem of traditional breaking machines breaking vertically stacked blanks, where the blanks are easily damaged or even breakage fails due to their own weight, resulting in greater adhesion. This wet breaking machine has a clever structure, high breaking efficiency and accuracy, and is less likely to damage the blanks, thus improving the yield of concrete blocks or panels.

[0006] The aforementioned applications all involve technical improvements to aerated concrete block splitting equipment, but none of them propose an effective solution for the automatic replacement of the splitting chuck. Utility Model Content

[0012] The length of the clamp head extends a greater distance than the width; under the drive of the drive assembly, the clamp head rotates at a certain angle and uses its length portion to engage with the loading and unloading hole on the clamp unit.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] (1) The present invention provides an automatic replacement mechanism for the splitting clamp of aerated concrete panels. The clamp is driven by a rotating shaft to pass through the loading and unloading hole on the clamp unit. Then, under the drive of the drive component, it rotates at a certain angle and uses the part of the clamp in the length direction to complete the clamping with the loading and unloading hole on the clamp unit. Then, the entire clamp unit is moved to complete the replacement operation of the clamp unit. Compared with the traditional manual operation, it is more time-saving and labor-saving.

[0025] (2) The present invention provides an automatic replacement mechanism for the splitting clamp of aerated concrete panels.

This not only saves costs but also makes the replacement operation more convenient and faster. At the same time, the connecting part on the first rotating shaft adopts a square design, which is beneficial to the transmission operation with the second connecting rod.

[0026] (3) The present invention provides an automatic replacement mechanism for splitting clamps of aerated concrete panels. The second rotating shaft is sleeved inside the first rotating shaft, so that the end of the first rotating shaft forms a limiting platform, thereby limiting the downward distance of the rotating shaft. At the same time, the space between the two rotating shafts is connected to the atmosphere through air holes, which facilitates the matching operation between the two.

[0027] (4) The automatic replacement mechanism for splitting clamps of aerated concrete panels of this utility model can control the rotation angle of the rotating shaft by setting limit posts at both ends of the first connecting rod, so as to ensure the accuracy of the clamping of the clamp head and the clamping unit.

[0028] (5) The automatic replacement mechanism for splitting clamps of aerated concrete panels of this utility model, after the clamping head and the clamping unit are connected, uses a pressing plate to press from the top of the clamping unit, thereby effectively ensuring the stability of the clamping unit during the later movement process.

[0042] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0043] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] The present invention will be further described below with reference to specific embodiments.

[0045] like Figure 1 As shown, this embodiment of an automatic replacement mechanism for the splitting clamps of aerated concrete panels includes an installation platform 11, a rotating shaft 12, and a drive assembly 14. One end of the rotating shaft 12 is rotatably mounted on the installation platform 11 via a bearing and connected to the drive assembly 14; the other end extends to the bottom of the installation platform 11 and is equipped with a clamping head 13. The drive assembly 14 is also mounted on the installation platform 11. This drive assembly 14 drives the rotating shaft 12 and its clamping head 13 to rotate, thereby completing the engagement or disengagement operation with the clamping head unit 4.

[0046] As shown in Figure 7, the chuck unit 4 to be replaced in this embodiment includes a mounting base 42 and a plurality of chucks 41 arranged along the length of the mounting base 42. Meanwhile, the mounting base 42 has mounting holes for the chucks 13 to pass through before rotation and to engage with the chucks 13 after rotation.

[0047] Specifically, refer to Figure 6As shown, the length dimension L1 of the latch 13 is greater than the width dimension L2. Similarly, the loading / unloading hole also needs to have different dimensions in both directions so that after the latch 13 passes through the loading / unloading hole, it can rotate, and its length portion can be engaged at the bottom of the loading / unloading hole, providing support to the bottom of the mounting base 42. It should be noted that although length and width are mentioned above, this does not mean that the latch 13 must be a rectangular structure. The latch 13 can be rectangular, elliptical, oblong, or other shapes with different dimensions in at least two directions.

[0048] Specifically, in this embodiment, the cross-section of the clip 13 is an oblong shape, and the sides of the clip 13 are chamfered. That is to say, the clip 13 has an overall inverted pyramid structure that is larger at the top and smaller at the bottom, so as to facilitate insertion into the loading and unloading hole on the mounting base 42. Similarly, the loading and unloading hole is also an oblong shape.

[0049] In this embodiment, since the clamp 13 is a load-bearing component, it will wear out or even be damaged after long-term use, and therefore needs to be replaced frequently. Therefore, the specific structural design of the rotating shaft 12 is further optimized in this embodiment, with the aim of reducing replacement costs and improving replacement efficiency.

[0050] refer to Figure 3 As shown, the rotating shaft 12 includes a first rotating shaft 121 and a second rotating shaft 122 that are detachably connected. The first rotating shaft 121 has a connecting portion 1211 for connecting and transmitting power with the drive assembly 14. Preferably, the connecting portion 1211 has a square structure and a mounting hole. The clamp 13 is located at the end of the second rotating shaft 122. The clamp 13 and the second rotating shaft 122 can be integrally formed or welded together; this is not limited here. With this design, when the clamp 13 needs to be replaced, only the second rotating shaft 122 needs to be replaced, without replacing the entire rotating shaft 12, saving on parts costs. Simultaneously, there is no need to disassemble the assembly bearing between the rotating shaft 12 and the mounting platform 11, making the replacement of the clamp 13 more convenient and quick.

[0051] Furthermore, the first rotating shaft 121 and the second rotating shaft 122 are connected by a sleeve connection. Specifically, refer to... Figure 4 , Figure 5As shown, a mounting hole is formed at the bottom of the first rotating shaft 121, and the end of the second rotating shaft 122 away from the chuck 13 extends into the mounting hole. Simultaneously, locking holes are formed on both the first and second rotating shafts 121 and 122. After the second rotating shaft 122 is assembled, a pin 123 can pass through the corresponding locking hole to complete the locking connection between the two rotating shafts. Compared to the threaded connection of a transmission, during the rotation of the rotating shaft 12, a pressure relief phenomenon may occur between the first and second rotating shafts 121 and 122, thus affecting the stability of the connection between them. However, the connection method using a sleeve and pin in this embodiment can better ensure the stability of the rotating shaft 12 during rotation.

[0052] In some embodiments, a recessed mounting surface 1212 is provided on the outer peripheral wall of the first rotating shaft 121, and the aforementioned pin 123 is located within the mounting surface 1212, so that the pin 123 does not protrude from the outer peripheral wall of the first rotating shaft 121 after assembly, so as to avoid interference with the mounting and dismounting hole.

[0053] In this embodiment, the pin 123 can be used to limit the axial movement and circumferential rotation of the second rotating shaft 122. However, if the distance between the outer wall of the second rotating shaft 122 and the inner wall of the mounting hole is large, it will also affect the stability of the second rotating shaft 122. Therefore, in this embodiment, the second rotating shaft 122 and the mounting hole are preferably fitted with a small clearance. At the same time, an air hole 1213 is provided on the peripheral wall of the first rotating shaft 121 to connect the space inside the mounting hole with the atmosphere, so as to overcome the air resistance during the assembly process and ensure the smooth installation of the second rotating shaft 122.

[0054] Furthermore, since the second rotating shaft 122 is sleeved inside the first rotating shaft 121, a limiting platform can be formed at the end of the first rotating shaft 121. When the chuck 13 moves downward in the loading and unloading hole, the mutual abutment between the limiting platform and the upper surface of the mounting base 42 can be used to limit the movement, thereby ensuring the accuracy of the descent position of the chuck 13.

[0055] refer to Figure 2 As shown, in some embodiments, the side of the mounting platform 11 is also provided with a clamping plate 15, which is connected to a drive source, such as a cylinder or an electric actuator. After the chuck unit 4 is locked in place by the chuck head 13, the clamping plate 15 is used to press it from the top of the chuck unit 4, thereby effectively ensuring the stability of the chuck unit 4 during subsequent movement.

[0056] refer to Figure 1 , Figure 2As shown, in one specific embodiment of the drive assembly 14, the drive assembly 14 includes a cylinder 143, a first connecting rod 141, and a second connecting rod 142. One end of the cylinder 143 is connected to the mounting platform 11, and the other end is hinged to a lug on the first connecting rod 141. The end of the first connecting rod 141 is hinged to the second connecting rod 142, and the second connecting rod 142 is fitted onto the connecting portion 1211 of the rotating shaft 12 through a slot thereon. Simultaneously, bolts and washers are fitted into the mounting holes on the connecting portion 1211 to limit the movement of the second connecting rod 142.

[0057] Furthermore, limit posts 144 are provided on the installation platform 11 at both ends of the first connecting rod 141 to control the rotation angle of the rotating shaft 12, so as to ensure the accuracy of the engagement between the clamp head 13 and the clamp unit 4.

[0058] Specifically, in this embodiment, each end of the first connecting rod 141 is connected to a second connecting rod 142, and each second connecting rod 142 is connected to a rotating shaft 12. That is, in this embodiment, each chuck unit 4 is equipped with two rotating shafts 12 to further ensure the stability of the chuck unit 4 during transport. Simultaneously, the drive assembly 14 is also provided in two sets, allowing for simultaneous replacement of two sets of chuck units 4 to improve work efficiency.

[0059] This embodiment of an automatic replacement mechanism for aerated concrete panel splitting clamps involves a rotating shaft 12 driving a clamping head 13 through a loading / unloading hole on a clamping unit 4. Then, driven by a drive assembly 14, the clamping head 13 rotates at a certain angle, and the length portion of the clamping head 13 engages with the loading / unloading hole on the clamping unit 4. The entire clamping unit 4 is then moved to complete the replacement operation. Compared to traditional manual operation, this is more time-saving and labor-saving.

[0060] In addition, this embodiment also provides an automatic replacement device for the splitting clamps of aerated concrete panels, which includes a frame 3 and a moving mechanism 2 slidably mounted on the frame 3. The moving mechanism 2 is connected to the replacement mechanism 1 and can drive the replacement mechanism 1 to move in the horizontal and vertical directions, so as to realize the switching of the replacement mechanism 1 between different work positions.

[0061] Specifically, refer to Figure 8 , Figure 9 As shown, the frame 3 includes a frame formed by horizontal and vertical beams, and support legs located at the bottom of the frame. Slide rails are provided on the vertical beams of the frame. Meanwhile, a placement platform 31 for placing the chuck unit 4 is provided below the frame, and a passageway is provided in the middle of the placement platform 31 for the movement of the moving mechanism 2 and the replacement mechanism 1.

[0062] refer to Figure 10As shown, the moving mechanism 2 includes a horizontal bar 21, a vertical bar 22, and a moving frame 23. The moving frame 23 is slidably mounted on the horizontal bar 21, with both ends of the horizontal bar 21 slidably mounted on the slide rails of the frame's longitudinal beam. The vertical bar 22 is perpendicular to the horizontal bar 21, and the vertical bar 22 is also slidably connected to the moving frame 23. The replacement mechanism 1 is connected to the bottom of the vertical bar 22 via its mounting platform 11. This design allows the replacement mechanism 1 to move horizontally in the first direction (X-direction) by sliding the horizontal bar 21 on the frame's longitudinal beam; it can also move horizontally in the second direction (Y-direction) by sliding the moving frame 23 on the horizontal bar 21; and it can move vertically in the Z-direction by sliding the vertical bar 22 on the moving frame 23. Of course, the horizontal bar 21, vertical bar 22, and moving frame 23 each need to be connected to their respective drive motors.

[0063] The automatic replacement device for the splitting clamp of aerated concrete panels according to this embodiment has the following working process.

[0064] First, the moving mechanism 2 drives the replacement mechanism 1 to move above the chuck unit 4 to be disassembled; and ensures that the chuck head 13 of the replacement mechanism 1 and the loading and unloading hole on the chuck unit 4 are in corresponding positions.

[0065] Next, the vertical rod 22 slides downward, allowing the clamp 13 to pass through the loading and unloading hole; then, the cylinder 143 is activated to drive the clamp 13 to rotate in order to complete the clamping operation with the clamp unit 4.

[0066] Then, the moving mechanism 2 drives the replacement mechanism 1 and the chuck unit 4 to move as a whole, and the replaced chuck unit 4 is placed on the placement platform 31; then, the cylinder 143 drives the chuck head 13 to rotate and disengage from the chuck unit 4, thus completing the disassembly operation of the chuck unit 4.

[0067] Repeat the above steps to grab a new chuck unit 4 and move it to the position of the original chuck unit 4; then, start the cylinder 143 to drive the chuck head 13 to rotate and disengage from the new chuck unit 4 to complete the installation operation of the new chuck unit 4.

[0068] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
