DETAILED DESCRIPTION

[0044] The principle and spirit of the present invention will be described below with reference to several exemplary embodiments shown in the accompanying drawings. It should be understood that these embodiments are described only to enable those skilled in the art to better understand and implement the present invention, and are not intended to limit the scope of the present invention in any way.

[0045] Please refer to Figure 1-5 , an embodiment of the present invention provides an automatic demolding device for a prefabricated component production mold, including a base 1, a wheel group is provided below the base 1, specifically, four wheels 2 are provided under the base 1 (the wheels 2 can also be configured with a motor to achieve automatic walking). A lifting device, a front-and-rear moving device, and a mold pulling device are provided on the base 1. The lifting device controls the movement of the mold pulling device in the vertical direction to adjust it to the same horizontal position as the mold to be removed. The front-and-rear moving device controls the movement of the mold pulling device in the front-and-rear direction, and is used to transport the mold pulling device to a position close to the mold so that the mold pulling device can be connected to the part to be removed in the prefabricated component production mold. The part to be removed is generally a core mold 3 in the prefabricated component, and the core mold 3 is provided with a component that can cooperate with the mold pulling device. There are many specific forms, such as a hanging shaft 301 (such as Fig.10 After the mold pulling device is connected to the part to be removed in the prefabricated component production mold, a pulling action is performed to remove it from the prefabricated component, and then it is reset.

[0046] The main components of the automatic mold removal equipment provided by the embodiment of the present invention are introduced and described in more detail below.

[0047] The mold pulling device includes a hook 4 and a first driving mechanism. The first driving mechanism and the hook 4 are both connected to the forward and backward moving device and can move with the forward and backward moving device. The hook 4 is connected to the first driving mechanism so that the first driving mechanism drives the hook 4 to move, thereby realizing the connection, pulling and unhooking of the hook 4 and the part to be removed in the prefabricated component production mold (the hanging shaft 301 of the core mold 3). A fixed first top plate 5 is also provided above the hook 4 to support the other parts of the mold so that the core mold 3 can be pulled out more smoothly.

[0048] Specifically, the hooks 4 are arranged in two rows in parallel, and a first transmission plate 6 is arranged outside each row of hooks 4. One end of the first transmission plate 6 close to the head of the hook 4 is hinged to the upper end of the front-rear moving device through a cross shaft, that is, located at the bottom end of the head of the hook 4. A first sliding groove 7 is opened in the middle of the first transmission plate 6. The first sliding groove 7 of the first transmission plate 6 is connected to the middle of the hook 4 through a first sliding member 8. The first sliding member 8 can be a screw structure and can move in the first sliding groove 7.

[0049] The ends of the two rows of first transmission plates 6 are hinged by a transverse connecting rod 9, and the side of the transverse connecting rod 9 close to the head of the hook 4 is connected to the push rod of the oil cylinder 10. The other end of the oil cylinder 10 is fixed to a fixed plate 11 located on the front and rear moving device. The push rod of the oil cylinder 10 is far away from the head of the hook 4, so that the cylinder body of the oil cylinder 10 can be placed on the inner side of the two rows of hooks 4, saving space in the linear direction. Especially when the front and rear moving device has occupied a part of the space in the linear direction, this design can make the space of the demoulding equipment in the linear direction more compact.

[0050] Before starting work, the oil cylinder 10 is in a retracted state, the first transmission plate 6 is in an upright state, and the hook 4 is in a high position. When the mold needs to be removed, the push rod of the oil cylinder 10 starts to push out, the first sliding member 8 moves in a direction away from the fulcrum, the first transmission plate 6 falls, and the hook 4 also falls at this time, hooking the corresponding connecting member in the mold, and then unloading the force, that is, the mold is separated from the prefabricated component under the pull of the hook 4, and the bonding force between the two is removed, and then the front and rear moving device is used to withdraw backwards to pull out the part to be removed in the mold. After the removal is completed, the oil cylinder 10 retracts again, the first sliding member 8 moves in a direction close to the fulcrum, the first transmission plate 6 stands up, and the hook 4 also moves upward to complete the decoupling from the removed part.

[0051] The above description takes the hook 4 facing downward as an example, which is mainly used to remove the mold of a straight wall. Of course, the hook 4 can also be turned 90°, and the relevant driving mechanism is also turned 90°. In this case, the hook 4 faces the horizontal direction (such as Figure 6 It is mainly used to remove the molds of L-angle walls and T-shaped walls.

[0052] The lifting device includes a lifting frame and a second driving mechanism connected to the lifting frame. The second driving mechanism drives the lifting frame to perform lifting movements. Its main function is to adjust the height of the entire equipment so that the hook 4 can be aligned with the height of the mold.

[0053] In this embodiment, the lifting frame is a scissor-type lifting frame 12, that is, it includes two rows of scissor-shaped brackets arranged in a substantially X shape, each scissor-shaped bracket is composed of two channel steels, and the middle parts of the two channel steels are hinged to each other. The second driving mechanism includes a transmission assembly connected to the side of the scissor-type lifting frame 12 away from the hook 4, and the transmission assembly includes a second transmission plate 13 and a second sliding member 14. There are four second transmission plates 13, each second transmission plate 13 is connected to the end of a channel steel, and a second sliding groove 15 is provided on the second transmission plate 13. The two rows of scissor-shaped brackets are connected by a second sliding member 14, and the second sliding member 14 is a horizontal rod, and the two ends are respectively connected to a second sliding groove 15. There are two second sliding members 14, one is located at the upper end of the two rows of scissor-shaped brackets, and the other is located at the lower end. The second driving mechanism also includes a first lead screw 16 that moves in a straight line and is arranged on the base 1, and a first driving motor 17 that drives the first lead screw 16. Of course, the first lead screw 16 and the motor can also be replaced by other driving and transmission mechanisms such as a linear motor, an oil cylinder, and a pneumatic cylinder.

[0054] It should be noted that this embodiment only illustrates the structure of the lifting device, and other common lifting platforms may also be used to implement it.

[0055] The forward and backward moving device includes a slide rail 18 arranged on the lifting frame and a moving frame 19 matched with the slide rail 18. The mold drawing device is arranged at one end of the moving frame 19, and the other end of the moving frame 19 is connected to the third driving mechanism. In this embodiment, the moving frame 19 is generally a cubic structure formed by welding a plurality of steel pipes, and the hook 4 is located at the front end of the cubic structure. A fixed plate 11 is also vertically arranged at the front end of the moving frame 19 for fixing and connecting the first top plate 5. The first transmission plate 6 mentioned above can be hinged at the lower part of the fixed plate 11. The steel pipe constituting the bottom of the moving frame 19 is nested in the slide rail 18. A second lead screw 20 that moves in a straight line and a second drive motor 21 that drives the second lead screw 20 are connected to the rear end of the moving frame 19. Of course, the second lead screw 20 and the second drive motor 21 can also be replaced by common drive devices such as a linear motor, an oil cylinder 10, and a pneumatic cylinder.

[0056] The function of the forward and backward moving device is to allow the hook 4 to approach the mold, and after the hook 4 is connected to the mold (connected to the hanging shaft 301), the mold can be pulled out. A position sensor can also be configured on the hanging shaft 301 to detect whether the hook 4 has approached a suitable position.

[0057] The base 1 is also provided with a gas station 22, a distribution box 23 and a remote control signal receiving device 24. The gas station 22 is used to provide power for the oil cylinder 10. The distribution box 23 provides power for each group of motors. The remote control signal receiving device 24 can use various common receiving ends for remote control. The output end of the remote control signal receiving device 24 can connect various driving mechanisms with signals to transmit control signals, especially it can be expanded to application scenarios of remote control such as mobile phone APP and 5G.

[0058] The automatic mold removal device is provided with limiters 25 at the front and rear. When the device moves to a position that can be detected by the limiters, the power source of the automatic mold removal device is automatically cut off.

[0059] like Figure 7-8 As shown, the base 1 is also provided with a first conveyor belt 26, a first robotic arm 27 and a first mold collection box 28; the first conveyor belt 26 is arranged below the mold pulling device, and is used to receive the core mold 3 removed from the mold pulling device, and the first robotic arm 27 is used to move the removed core mold 3 to the first mold collection box 28, thereby further improving the degree of automation of the entire production operation.

[0060] like Fig. 9 As shown, further, the base 1 is also provided with a second conveyor belt 29, a second mechanical arm 30, and a second mold collection box 32. The second conveyor belt 29 is used to convey the disassembled upper module 31 (the upper module 31 is connected to the core mold 3 and is located on the upper part of the core mold 3. The upper module 31 is used to form a concrete pouring channel, and the core mold 3 is used to form a cast-in-place cavity. The upper module 31 is removed from the top of the mold, and the core mold 3 is removed from the bottom), and the second mechanical arm 30 is used to move the upper module 31 to the second mold collection box 32. The second conveyor belt 29 and the second mechanical arm 30 can also be used to move integrated full-length modules.

[0061] The automatic mold removal equipment described above can be set up in multiple groups in parallel (such as Fig.10 As shown in the figure, multiple sets of molds can be removed at one time, further improving work efficiency. After these disassembly and movement components are integrated on the automatic mold removal equipment, a small automated workstation is formed, which greatly saves labor costs.

[0062] In some other embodiments, such as Figure 11-13 As shown, the demolding equipment can also be equipped with a set of supporting oil cylinders 33 for supporting the mold platform or mold during demolding. Its function is that when demolding, the upper forward and backward moving device shrinks and is supported on the mold or mold platform by the supporting oil cylinders 33 to play a stabilizing role. The positions of the supporting oil cylinders 33 can be various, such as Fig.11 , 12 On both sides of the lifting frame, Fig.13 It is below the lifting platform.

[0063] In other embodiments, if the friction between the mold and the concrete is large during the demolding process, for example, when the mold is removed after the concrete is completely solidified, since the friction at this time is larger than when the concrete is not completely solidified, a second top plate 34 is further provided on the opposite side of the first top plate 5. Figure 14-16 shown.

[0064] In other embodiments, the moving frame 19 is divided into two sections, the front section is a rotating frame 35, and the hook, the first top plate, the oil cylinder, the first transmission plate, the first sliding groove, the first sliding member, and the transverse connecting rod are all arranged on the rotating frame 35. In this way, the hook and other components used to disassemble the mold can be switched back and forth in the horizontal and vertical directions, and a set of equipment can be simultaneously applicable to the removal of a straight wall (such as Fig.17 working state) and L-angle wall (such as Fig.18 dismantling of the working state).

[0065] It should be noted that the relevant equipment responsible for transporting the mold in this embodiment can also be used separately from the equipment used for removing the mold assembly.

[0066] This embodiment also provides a working method of the automatic demoulding device for the prefabricated component production mold, including:

[0067] S1: Control the automatic demoulding device to move to the working position, for example, the movement of the entire device can be controlled by pushing or using a control system (with the help of wheels 2 under the base 1),

[0068] S2: Control the lifting device to adjust it to a suitable height and align it with the mold;

[0069] S3: Control the forward and backward moving device and adjust it to a suitable distance so that the hook 4 can be connected to the mold;

[0070] S4: Control the mold pulling device (specifically the hook 4 part) to connect with the part to be disassembled in the mold, remove the binding force between the mold and the prefabricated component, and then make it pull out the part to be disassembled, and then control the mold pulling device to separate from the removed part of the mold and reset. The specific process of step S4 can refer to the description of the action of the hook 4 above.

[0071] Generally speaking, step S4 includes two actions: unloading the force and pulling out the mold.

[0072] Next, the mold can be moved, recycled, and other operations can be performed to achieve a closed production loop.

[0073] Limiters 25 are arranged at the front and rear of the automatic mold removal device. When the device moves to a position that can be detected by the limiters 25, the power source of the automatic mold removal device is automatically cut off.

[0074] The invention concept is described in detail using specific examples herein, and the description of the above embodiments is only used to help understand the core idea of ​​the invention. It should be pointed out that any obvious modification, equivalent substitution or other improvement made by a person of ordinary skill in the art without departing from the invention concept should be included in the protection scope of the present invention.
