Description

Technical Field

[0001] This invention relates to the field of precast concrete component production equipment technology, and in particular to a novel mold stacking and destacking machine. Background Technology

[0002] Currently, on intensive precast concrete component production lines, components poured on molds are stacked together with multiple molds to form a stack, which is then sent to a curing kiln for curing. After curing, the stack is disassembled into single layers and returned to the production line to continue its circulation.

[0003] Most common stacker / destacking machines currently use winch lifting. Since the winch lifting is located at the top of the elevator, it lifts the mold table from above. In addition, the space required for lifting the mold table is large, so the stacking mechanism must be lifted to a height higher than the entire stack so that the entire stack can flow in and out. Because the lifting frame reaches 3-3.5m or more, the equipment structure is relatively complex and the manufacturing cost is high. Summary of the Invention

[0004] To reduce the height of the frame and decrease equipment costs, this invention provides a novel formwork stacking and destacking machine.

[0005] The novel stacking and destacking machine for mold platforms provided by this invention adopts the following technical solution:

[0006] A novel formwork stacker / destacking machine includes a prefabricated platform, a lifting device, and a supporting sliding device;

[0007] The lifting device and the supporting sliding device are both installed on the prefabricated platform. The lifting device is used to lift the mold table, and the supporting sliding device is used to transport the mold table to one side of the lifting device. A frame is installed on the outside of the lifting device, and the frame is installed on the prefabricated platform.

[0008] The lifting device is equipped with a telescopic component for telescopically clamping the mold table and a lifting component for pushing the telescopic component up and down.

[0009] By adopting the above technical solution, the lifting device is installed on the prefabricated platform, that is, placed at a low position, so the space below can be utilized. The frame does not need to be made very high, only needing space for the mold platform to be lifted, which greatly reduces the height of the frame and reduces the cost of the equipment.

[0010] Preferably, the lifting device is provided in four sets, and the four sets of lifting devices are distributed in a square shape at the four corners.

[0011] By adopting the above technical solution, the mold table is relatively large, and a single lifting device cannot lift it flat. Four sets of lifting devices are installed at the four corners of the square, that is, at the four corners of the mold table. After the mold table is rotated, the lifting devices lift the mold table from the four corners, effectively ensuring the balance of the mold table.

[0012] Preferably, a steering unit is connected between the four sets of lifting devices, and the steering unit is connected to a reduction motor. The reduction motor is installed on the prefabricated platform, and the steering unit includes multiple universal drive shafts that are connected from the center of the square to the four lifting devices.

[0013] By adopting the above technical solution, a steering unit is installed between the four lifting devices, and only one geared motor is used, which greatly reduces the cost of the geared motor. Furthermore, through the linkage of the steering unit, the lifting devices operate synchronously, effectively ensuring that the four lifting devices are raised to the same height, and stably lifting the mold table.

[0014] Preferably, the lifting assembly includes a screw jack and a moving block, the moving block being threaded onto the screw jack, and a flat key connecting the universal drive shaft and the screw jack.

[0015] By adopting the above technical solution, the screw jack pushes the moving block to move up and down, and the universal drive shaft is connected to the screw jack through a flat key, providing power to the screw jack during rotation.

[0016] Preferably, the lifting assembly has guide rods parallel to the screw jack on both sides, the moving block is connected to the guide rods, the moving block is provided with a gripper, and the moving block is provided with a telescopic cylinder, the end of the telescopic cylinder away from the moving block is connected to the gripper.

[0017] By adopting the above technical solution, guide rods are set on both sides of the screw jack to prevent the moving block from rotating during the movement, which plays a limiting role and a guiding role. The moving block can only move up and down. The gripper on the moving block is pushed out or retracted by the telescopic cylinder, which effectively lifts the mold table.

[0018] Preferably, multiple supporting sliding devices are provided, arranged in two rows, and evenly arranged in the middle of the square formed by the lifting devices.

[0019] By adopting the above technical solution, the supporting sliding device is used to move the mold table from one side of the prefabrication platform to the other side. The mold table is relatively large, so two rows can be used to better support it. It is placed in the middle of the lifting device. The mold table is transported to the middle of the lifting device by the supporting sliding device, and the lifting device lifts it up by the gripper.

[0020] Preferably, the supporting sliding device includes a support base and a roller, the roller being rotatably mounted on the support base and mounted at the end away from the prefabrication platform.

[0021] By adopting the above technical solution, the support base is set to prevent the mold table from contacting the ground, and the lower space is left so that the gripper can extend under the mold table and then lift the mold table from the bottom. The support base is equipped with rollers, which can effectively propel the mold table forward and reduce the friction between the mold table and the support base when the mold table moves.

[0022] Preferably, a protective housing is provided at the connection between the universal drive shaft and the screw jack, and the protective housing is fixedly supported on the prefabricated platform.

[0023] By adopting the above technical solution, a protective shell is set between the universal drive shaft and the screw jack. Since the machine is constantly running and there is a certain degree of danger in the operation, a protective shell is wrapped around the outside to prevent workers from bumping into the running machine. The protective shell is fixedly supported on the prefabricated platform to support the universal drive shaft away from the ground.

[0024] Preferably, the universal drive shaft is connected to an incremental encoder, and there is only one incremental encoder. The incremental encoder is connected to the end of one of the universal drive shafts and is used to detect the rotation angle of the geared motor.

[0025] By adopting the above technical solution, the rotation angle of the geared motor is detected by an incremental encoder. Since the universal drive shafts are all operated by geared motors, in order to reduce costs, only an incremental encoder needs to be installed at the end of one of the universal drive shafts.

[0026] Preferably, the incremental encoder is connected to a processor, which is connected to a geared motor, and the processor controls the starting and stopping of the geared motor according to the rotation angle of the geared motor.

[0027] By adopting the above technical solution, when the incremental encoder detects a problem with the rotation angle of the geared motor and it is outside the set range, it immediately controls the geared motor to stop or adjust the rotation angle of the geared motor.

[0028] In summary, the present invention has the following beneficial technical effects:

[0029] 1. The lifting device is installed on the prefabricated platform, which is placed at a low position, so the space below can be utilized. The frame does not need to be made very high. It only needs to have space for lifting the mold table, which greatly reduces the height of the frame and reduces the cost of the equipment.

[0030] 2. The mold table is relatively large, and a single lifting device cannot lift it flat. Four sets of lifting devices are installed at the four corners of the square, that is, at the four corners of the mold table. After the mold table is rotated, the lifting devices lift the mold table from the four corners, effectively ensuring the balance of the mold table.

[0031] 3. A protective shell is installed between the universal drive shaft and the screw jack. Since the machine is constantly running, and there is a certain degree of danger in the operation of the machine, a protective shell is wrapped around the outside to prevent workers from bumping into the running machine. The protective shell is fixedly supported on the prefabricated platform to support the universal drive shaft away from the ground. Attached Figure Description

Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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. Therefore, they should not be construed as limitations on this invention.

[0040] This invention discloses a novel stacking and destacking machine for mold platforms. (Refer to...) Figure 1 The stacker / destacking machine includes a prefabricated platform 1, a lifting device 2, and a supporting sliding device 3;

[0041] The prefabricated platform 1 is a flat surface, or the ground can be used as the prefabricated platform 1. The lifting device 2 and the supporting moving device are both installed on the prefabricated platform 1. A frame 4 is set on the outside of the lifting device 2, and the frame 4 is also set on the prefabricated platform 1. The frame 4 plays a supporting role. The lifting device 2 is installed on the frame 4, and when it is lifted upward, the frame 4 is needed to stabilize it.

[0042] The lifting device 2 is installed on the prefabricated platform 1, which means it is placed at a low position, so the space below can be used. The frame 4 does not need to be made very high. It only needs to have space for lifting the mold table, which greatly reduces the height of the frame 4 and reduces the cost of the equipment.

[0043] Reference Figure 2 The lifting device 2 is used to raise and lower the mold table, and the supporting sliding device 3 is used to transport the mold table to one side of the lifting device 2. The lifting device 2 is equipped with a telescopic component for telescopically clamping the mold table and a lifting component for pushing the telescopic component to rise and fall.

[0044] In this embodiment, the lifting device 2 is provided in four sets, which are distributed in a square shape at the four corners. The mold table is relatively large, and a single lifting device 2 cannot lift it flat. The four lifting devices 2 are installed at the four corners of the square, that is, at the four corners of the mold table. After the mold table moves over, the lifting device 2 lifts the mold table from the four corners, effectively ensuring the balance of the mold table.

[0045] If the mold table is very large or very long, the number of lifting devices 2 can be increased appropriately. The lifting devices 2 must be evenly distributed in two rows. The additional number of groups should be installed on the long side of the square, and a few more lifting devices 2 should be installed in the middle position to effectively improve the stability of the mold table during lifting.

[0046] A steering gear unit 6 connects the four lifting devices 2. The steering gear unit 6 includes multiple universal drive shafts 7, which extend from the center of a square structure towards the four lifting devices 2. In this embodiment, six universal drive shafts are arranged in an "I" shape. Each stroke of the "I" shape has two universal drive shafts 7. The two universal drive shafts 7 that are in contact with each other are connected. A reduction motor 5 is installed between the two universal drive shafts 7 at the middle vertical line, which drives all six universal drive shafts 7 in a coordinated manner. The reduction motor 5 is mounted on the prefabricated platform 1.

[0047] Alternatively, four can be set up, connected diagonally from the center to four sets of lifting devices 2.

[0048] A steering unit 6 is installed between the four lifting devices 2, and only one geared motor 5 is used, which greatly reduces the cost of the geared motor 5. Furthermore, through the linkage of the steering unit 6, the lifting devices 2 operate synchronously, effectively ensuring that the four lifting devices 2 are raised to the same height, and stably lifting the mold table.

[0049] The lifting assembly includes a screw jack 8 and a moving block 9. The moving block 9 is threaded onto the screw jack 8 and can be pushed up or down by rotating the screw jack 8, similar to the function of a ball screw jack 8. A key connects the universal joint drive shaft 7 to the screw jack 8, and the universal joint drive shaft 7 and the screw jack 8 are connected by a worm gear transmission. The rotation of the universal joint drive shaft 7 provides power to the screw jack 8.

[0050] The universal drive shaft 7 rotates under the drive of the geared motor 5, which in turn drives the screw jack 8 to rotate via the screw thread, thereby driving the moving block 9 to move up and down, effectively realizing the lifting and lowering of the moving block 9.

[0051] A protective shell 15 is provided at the connection between the universal drive shaft 7 and the screw jack 8, and the protective shell 15 is fixedly supported on the precast platform 1. Since the machinery is constantly running, and there is a certain degree of danger in the running machinery, a protective shell is wrapped around the outside to prevent workers from bumping into the running machinery, and the protective shell is fixedly supported on the precast platform 1 to support the universal drive shaft 7 away from the ground.

[0052] Guide rods 10 parallel to the screw jack 8 are provided on both sides of the lifting assembly. The screw jack 8 and the guide rods 10 are both connected to the prefabricated platform 1 at the bottom and supported on the frame 4 at the top. The frame 4 needs to be set to the same height as the mold table needs to be lifted.

[0053] The movable block 9 is connected to the guide rod 10. The guide rod 10 prevents the movable block 9 from rotating during movement, and plays a limiting and guiding role, so that the movable block 9 can only move up and down.

[0054] The movable block 9 is equipped with a gripper 11 and a telescopic cylinder 12. The end of the telescopic cylinder 12 away from the movable block 9 is connected to the gripper 11. The gripper 11 on the movable block 9 is pushed out or retracted by the telescopic cylinder 12, effectively lifting the mold table.

[0055] Reference Figure 3The universal drive shaft 7 is connected to an incremental encoder 16. There is only one incremental encoder 16, which is connected to the end of one of the universal drive shafts 7. The incremental encoder 16 is used to detect the rotation angle of the geared motor 5.

[0056] A rotary coupling is connected to the end of the universal drive shaft 7 and the screw jack 8. One end of the rotary coupling is connected to the universal drive shaft 7, and the other end can be fixed to the frame 4 or the guide rod 10. It only needs to be fixed in one stationary position. When the universal drive shaft 7 rotates, it will drive the rotary coupling to rotate, so that the incremental encoder 16 detects the rotation angle. The detected angle is the rotation angle of the universal drive shaft 7, thereby obtaining the rotation angle of the geared motor 5.

[0057] The rotation angle of the geared motor 5 is detected by the incremental encoder 16. Since all the universal drive shafts 7 are driven by the geared motor 5, in order to reduce costs, only one of the universal drive shafts 7 needs to be equipped with an incremental encoder 16 at its end.

[0058] The incremental encoder 16 is connected to a processor, which is connected to the geared motor 5. The processor controls the start and stop of the geared motor 5 based on the rotation angle of the geared motor 5. When the incremental encoder 16 detects a problem with the rotation angle of the geared motor 5, which is outside the set range, it immediately controls the geared motor 5 to stop or adjust the rotation angle of the geared motor 5.

[0059] It should be noted that both the incremental encoder 16 and the processor are existing devices.

[0060] Reference Figure 4 and Figure 5 Multiple supporting sliding devices 3 are provided, arranged in two rows, and the multiple supporting sliding devices 3 are evenly arranged in the middle of the square formed by the lifting device 2.

[0061] The supporting sliding device 3 is used to move the mold table from one side of the prefabrication platform 1 to the other side. The mold table moves along the long side of the mold table. The mold table is relatively large, so two rows are used to better support it. It is placed in the middle of the lifting device 2. The mold table is transported to the middle of the lifting device 2 by the supporting sliding device 3. The lifting device 2 lifts it up by the gripper 11.

[0062] The supporting sliding device 3 includes a support base 13 and rollers 14. The rollers 14 are rotatably mounted on the support base 13 and are installed at the end away from the precast platform 1. The support base 13 is designed to prevent the mold table from contacting the ground and to leave space at the bottom so that the gripper 11 can extend under the mold table and lift it from the bottom. The rollers 14 on the support base 13 can effectively propel the mold table forward and reduce the friction between the mold table and the support base 13 when the mold table moves.

[0063] The implementation principle of a novel mold platform stacking and destacking machine according to an embodiment of the present invention is as follows: A mold platform moves to the vicinity of the lifting device 2 via the supporting sliding device 3. The lifting device 2 moves the gripper 11 to a height lower than the mold platform, and then extends the gripper 11 through the telescopic cylinder 12. The lifting component lifts the mold platform, raising it. A new mold platform then moves to the vicinity of the lifting device 2. The lifting device 2 lowers the upper mold platform and stacks it together with the newly arrived mold platform. The gripper 11 is pulled out from between the upper mold platform and the new mold platform, and then the gripper 11 is moved to the bottom of the new mold platform. The gripper 11 extends from the bottom of the new mold platform, lifting all the mold platforms again. The above actions of entering the new mold platform are repeated to effectively stack the mold platforms.

[0064] During destacking, the mold platform is first lowered onto the supporting sliding device 3, then raised from the second-to-last mold platform. The lowest mold platform is then moved out via the supporting sliding device 3. This process is repeated to effectively destacking the mold platforms.

[0065] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
