Abstract
Description
Technical Field
[0001] The invention relates to the technical field of concrete component moulds, in particular to a quick demoulding device for assembled concrete components. Background Art
[0002] In the modern construction industry, prefabricated concrete components have been widely used due to their advantages such as fast construction speed, controllable quality, energy saving and environmental protection. In the production process of prefabricated concrete components, demolding is a crucial step. Traditional demoulding methods for prefabricated concrete components mainly rely on manual or simple mechanical assistance. During manual demoulding, workers need to use tools such as crowbars to manually separate the formwork from the concrete components. This method is not only labor-intensive and has extremely low work efficiency, but also in the process of prying the formwork, it is very easy to cause damage to the surface of the concrete component, affecting the quality and appearance of the component. Although mechanical-assisted demoulding has improved efficiency to a certain extent, it usually adopts the method of lifting the formwork as a whole, which requires that the concrete components have a high strength in all parts. Otherwise, during the lifting process, the concrete components are subjected to greater forces and are prone to cracks or even breaks, and the efficiency of reassembling multiple formworks after demoulding is low.

[0032] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.
[0033] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways than those specifically described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.
[0034] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.
[0035] Example 1, referring to Figures 1 to 16 , which is the first embodiment of the present invention. This embodiment provides a rapid demoulding device for precast concrete components. The rapid demoulding device for precast concrete components includes a main body assembly 100, which includes a bottom plate 101. A positioning seat 102 is fixed on the top of the bottom plate 101. A pulling seat 103 is arranged on one side of the positioning seat 102. A bottom formwork 104 is fixed on the top of the pulling seat 103. Here, the number of the bottom formworks 104 is five. In actual use, those skilled in the art can set it according to needs. A pulling seat 103 is fixed below each bottom formwork 104, and a positioning seat 102 that cooperates with the pulling seat 103. By moving the pulling seat 103 downward, the bottom formwork 104 can be moved downward, so that the bottom formwork 104 moves away from the concrete component on its top. The air pipes used in this device are all high-pressure resistant air pipes, which meet the required air pressure for use. This is prior art, and those skilled in the art can clearly understand it, so it will not be elaborated here.
[0036] Before adding concrete into the mold each time, a demoulding agent needs to be sprayed on the surface of the mold to facilitate the demoulding of the concrete component.
[0037] Supporting members 105 are arranged at the bottom of the bottom formwork 104. The supporting members 105 are used to support the bottom formwork 104, so that the bottom formwork 104 has sufficient supporting force to support the concrete component. Four supporting members 105 are arranged at the four corners of the bottom of the bottom formwork 104, so that the bottom formwork 104 can be stably supported. A side formwork 106 is arranged on one side of the bottom formwork 104. The number of the side formworks 106 is four, which are used to surround the multiple bottom formworks 104, so that concrete can be poured on the tops of the multiple bottom formworks 104. A mold closing member 107 is arranged on one side of the side formwork 106. The mold closing member 107 can be used to support the side formwork 106 and enable a single side formwork 106 to swing. The mold closing member 107 is used to push the four side formworks 106 to merge into a circle, so as to complete the surrounding of the multiple bottom formworks 104.
[0038] The demolding assembly 200 is disposed on the positioning seat 102 and includes a demolding member 201 disposed on the positioning seat 102. The demolding member 201 is used to drive the bottom formwork 104 and the concrete member to separate. The demolding member 201 includes a fixed sleeve 201a fixed to the inner top wall of the positioning seat 102. A lifting sleeve 201b is disposed on the surface of the fixed sleeve 201a. A sealing structure similar to a sealing ring is disposed at the connection between the fixed sleeve 201a and the lifting sleeve 201b, so that air leakage does not occur at the connection between the two. This is the prior art and can be clearly understood by those skilled in the art, so it will not be elaborated here. A piston 201c is disposed in the lifting sleeve 201b. The connection between the piston 201c and the lifting sleeve 201b is sealed. A first spring 201d is fixed to the bottom of the piston 201c. The first spring 201d is in a compressed state. The other end of the first spring 201d is fixed to the inner bottom wall of the lifting sleeve 201b. A through hole is formed at the bottom of the lifting sleeve 201b, so that when the piston 201c descends, the air at the corresponding position of the lifting sleeve 201b can be discharged. A positioning ring 201e is fixed to the inner wall of the lifting sleeve 201b. The positioning ring 201e is used to position the piston 201c. An extrusion sleeve 201f is fixed to the top of the piston 201c, so that the piston 201c can drive the extrusion sleeve 201f to perform synchronous lifting and moving. A sealing sleeve 201g is fixed to the inner top wall of the fixed sleeve 201a. The sealing sleeve 201g slides in the extrusion sleeve 201f, and the connection between the extrusion sleeve 201f and the sealing sleeve 201g is sealed. An air charging pipe 201h is fixed in the positioning seat 102. A sealing bladder 201i is embedded around the bottom formwork 104. The sealing bladder 201i is an integral annular airbag, and the sealing bladder 201i is communicated with the air charging pipe 201h. In the illustrated state, the sealing bladder 201i is in an expanded state, and adjacent sealing bladders 201i can be mutually extruded, so as to fill the gap between the bottom formworks 104, thereby preventing concrete from falling through the gap between the bottom formworks 104.
[0039] When it is necessary to separate the bottom formwork 104 from the concrete member, high-pressure gas is introduced into the fixed sleeve 201a, increasing the air pressure inside the fixed sleeve 201a. At this time, the high-pressure gas inside the fixed sleeve 201a will push the piston 201c, causing the piston 201c to move downward. At the same time, the piston 201c drives the extrusion sleeve 201f to move downward, causing the extrusion sleeve 201f to move away from the sealing sleeve 201g, reducing the air pressure between the sealing sleeve 201g and the extrusion sleeve 201f. Thereby, the air pressure of the sealing bladder 201i is reduced, causing the sealing bladder 201i to contract into the bottom formwork 104, so that the bottom formwork 104 can be smoothly separated from other bottom formworks 104. As the gas in the fixed sleeve 201a continues to increase, the piston 201c can continue to move downward. When the piston 201c moves to the inner bottom wall of the lifting sleeve 201b, the lifting sleeve 201b can be pushed downward, causing the lifting sleeve 201b to move downward. Thereby, the lifting sleeve 201b drives the pulling seat 103 to move downward, so that the pulling seat 103 drives the bottom formwork 104 to move downward. At this time, the concrete member remains in place under the support of other bottom formworks 104, so that this bottom formwork 104 is separated from the concrete member separately.
[0040] Embodiment 2, refer to Figures 1 to 16 , is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.
[0041] Specifically, the demoulding assembly 200 further includes an air delivery member 202 disposed on one side of the positioning seat 102, including a fixed frame 202a fixed to one side of the positioning seat 102. An air delivery pipe 202b is fixed inside the fixed frame 202a. A reversing wheel 202c is rotatably connected inside the fixed frame 202a. A connecting pipe 202d is fixed inside the fixed frame 202a. A flow channel 202c-1 is provided inside the reversing wheel 202c. The number of the flow channels 202c-1 is two. The connecting pipe 202d is communicated with the fixed sleeve 201a. The air delivery pipe 202b can be communicated with the connecting pipe 202d through the flow channel 202c-1 provided in the reversing wheel 202c, so that the air delivery pipe 202b can deliver high-pressure gas into the fixed sleeve 201a.
[0042] Specifically, the gas delivery member 202 further includes a gas guide pipe 202e fixed within the fixing frame 202a. The gas guide pipe 202e is used to deliver the high-pressure gas input by the gas delivery pipe 202b to the demolding assembly 200 below the next bottom template 104. An exhaust passage 202a-1 is provided within the fixing frame 202a, and the exhaust passage 202a-1 is used to discharge the high-pressure gas within the fixing sleeve 201a. When the reversing wheel 202c rotates 90 degrees from the current state, the flow passage 202c-1 can be moved, so that the gas delivery pipe 202b and the gas guide pipe 202e are communicated, and the exhaust passage 202a-1 and the connecting pipe 202d are communicated, enabling the high-pressure gas within the fixing sleeve 201a and the lifting sleeve 201b to be discharged from the exhaust passage 202a-1 through the connecting pipe 202d and the flow passage 202c-1, thereby reducing the air pressure within the fixing sleeve 201a and the lifting sleeve 201b and enabling the bottom template 104 to have the condition for reset movement.
[0043] Specifically, the demolding assembly 200 further includes an adjusting member 203 provided within the fixing frame 202a, including rotating shafts 203a fixed on both sides of the reversing wheel 202c. The two rotating shafts 203a are used to support the reversing wheel 202c. A torsion spring 203b is fixed on the surface of the rotating shaft 203a. The torsion spring 203b is currently in a compressed state and is used to drive the rotating shaft 203a to rotate. Through the restoring force of the torsion spring 203b, the reversing wheel 202c can stay in the current state. An adjusting gear 203c is fixed on the surface of the other rotating shaft 203a. By rotating the adjusting gear 203c, the adjusting gear 203c can drive the rotating shaft 203a to rotate.
[0044] Specifically, the adjusting member 203 further includes a positioning groove 203a-1 provided on the surface of the rotating shaft 203a. The positioning groove 203a-1 is set to be arc-shaped. A positioning pin 203d is provided on one side of the positioning groove 203a-1. The positioning pin 203d is used to limit the rotating shaft 203a through the positioning groove 203a-1, so that the rotating shaft 203a will not rotate over the stroke under the elastic force of the torsion spring 203b and can be maintained in the current state. A lifting block 203e is provided within the fixing frame 202a. The positioning pin 203d is fixed on the top of the lifting block 203e. A second spring 203f is provided within the lifting block 203e. The second spring 203f is in a compressed state and can push the lifting block 203e with the second spring 203f, so that the positioning pin 203d can be pressed within the positioning groove 203a-1.
[0045] Specifically, the adjusting member 203 further includes a rack 203g slidably disposed within the fixed frame 202a. The rack 203g meshes with the adjusting gear 203c. A third spring 203h is fixed to the top of the rack 203g. At this time, the third spring 203h is in a compressed state. A sliding sleeve 203i is provided on the surface of the rack 203g. A limiting strip is fixed to the inner wall of the sliding sleeve 203i. A sliding groove is formed on the surface of the rack 203g. By sliding the limiting strip within the sliding groove, the sliding sleeve 203i can be prevented from moving out of the surface of the rack 203g under the push of the third spring 203h.
[0046] Specifically, the demolding assembly 200 further includes a positioning member 204 disposed on the top of the fixed frame 202a, including a support block 204a fixed to the top of the fixed frame 202a. A plug rod 204b is disposed within the support block 204a. A fourth spring 204c is fixed within the plug rod 204b. The fourth spring 204c is in a compressed state. A slot 203g-1 is formed on the surface of the rack 203g. The end of the plug rod 204b is inserted into the slot 203g-1. An extrusion block 204d is fixed to the top of the plug rod 204b. One side of the extrusion block 204d is inclined. When the sliding sleeve 203i moves downward, the sliding sleeve 203i can extrude the extrusion block 204d, so that the extrusion block 204d drives the plug rod 204b away from the slot 203g-1, thereby releasing the limitation on the rack 203g. A support shell 204e is fixed to the top of the fixed frame 202a. The air delivery pipe 202b is fixed within the support shell 204e. A connecting passage 204e-1 is formed within the support shell 204e. An input pipe 204f is fixed within the support shell 204e for inputting high-pressure gas. Through the connection of the connecting passage 204e-1, the high-pressure gas can enter the air delivery pipe 202b. A positioning rod 204g is disposed within the support shell 204e. The end of the positioning rod 204g is located on one side of the sliding sleeve 203i. A card slot 203i-1 is formed on the surface of the sliding sleeve 203i. The end of the positioning rod 204g can be inserted into the card slot 203i-1. The other end of the positioning rod 204g is fixed with a fifth spring 204h. The fifth spring 204h is currently in a normal state. When the input pipe 204f inputs high-pressure gas into the connecting passage 204e-1, the air pressure within the connecting passage 204e-1 can be increased, so that the high-pressure gas pushes the positioning rod 204g, thereby enabling the positioning rod 204g to extrude the sliding sleeve 203i. When the sliding sleeve 203i moves downward such that the card slot 203i-1 moves to the end of the positioning rod 204g, the positioning rod 204g can be inserted into the card slot 203i-1 at this time, thereby limiting the position of the sliding sleeve 203i.
[0047] Specifically, the demolding assembly 200 further includes a separating member 205 disposed on the top of the bottom plate 101, including a support frame 205a fixed to the top of the bottom plate 101. A first pulling plate 205b is fixed to the inner wall of the support frame 205a. A second pulling plate 205c is fixed to one side of the side template 106. A pushing plate 205d is fixed to the inner wall of the first pulling plate 205b. An airbag 205e is fixed to one side of the pushing plate 205d, and another pushing plate 205d is also fixed to the other side of the airbag 205e.
[0048] A pipeline is arranged on the surface of the airbag 205e. The air duct 202e of the last demolding assembly 200 can be connected to this pipeline, so as to inflate the airbag 205e, causing the airbag 205e to expand, thereby pushing the pushing plate 205d, enabling the pushing plate 205d to push the second pulling plate 205c, and causing the second pulling plate 205c to drive the side template 106 away from the concrete member.
[0049] The first pulling plate 205b, the second pulling plate 205c, the pushing plate 205d, and the airbag 205e are all arranged on the four side templates 106, so that the four side templates 106 can be away from the concrete member, thereby completing the demolding of the four side templates 106 from the concrete member.
[0050] Example 3, referring to Figures 1 to 16 , is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.
[0051] Specifically, the support member 105 includes a first support sleeve 105a fixed to the top of the bottom plate 101. A second support sleeve 105b is arranged inside the first support sleeve 105a. A sliding groove 105a-1 is formed inside the first support sleeve 105a. The second support sleeve 105b slides in the sliding groove 105a-1 to limit the stroke of the second support sleeve 105b. A sixth spring 105c is arranged inside the first support sleeve 105a. The sixth spring 105c is in a compressed state and is used to push the bottom template 104, so that the bottom template 104 has sufficient supporting force to support the concrete member.
[0052] Specifically, the mold clamping part 107 includes a support base 107a fixed to the top of the bottom plate 101. The side template 106 is rotatably connected to the surface of the support base 107a through a rotating shaft. A support plate 107b is fixed to one side of the side template 106. The support plate 107b is used to position the side template 106. When the support plate 107b falls on the top of the bottom plate 101, the side template 106 is in a vertical state. A seventh spring 107c is fixed to the other side of the side template 106. The seventh spring 107c is in a compressed state and is used to push the side template 106, so that the four side templates 106 are squeezed against each other, thereby ensuring the sealing performance at the connection. Rubber pads can be fixed at both ends of the side template 106. When the four side templates 106 are squeezed against each other, the rubber pads of adjacent side templates 106 can be squeezed against each other, so that the connection of the four side templates 106 is sealed.
[0053] During use, when it is necessary to demold the concrete member, first, high-pressure gas is input into the input pipe 204f, so that the air pressure in the connecting channel 204e-1 increases. Thereby, the high-pressure gas pushes the positioning rod 204g, so that the positioning rod 204g can squeeze the rack 203g. At the same time, the high-pressure gas enters the air delivery pipe 202b. Through the setting of the flow channel 202c-1, the air delivery pipe 202b conveys the high-pressure gas to the connecting pipe 202d, so that the air delivery pipe 202b can convey the high-pressure gas into the fixed sleeve 201a. By introducing high-pressure gas into the fixed sleeve 201a, the air pressure in the fixed sleeve 201a increases. At this time, the high-pressure gas in the fixed sleeve 201a pushes the piston 201c, so that the piston 201c moves downward. At the same time, the piston 201c drives the extrusion sleeve 201f to move downward, so that the extrusion sleeve 201f moves away from the sealing sleeve 201g, and the air pressure between the sealing sleeve 201g and the extrusion sleeve 201f decreases. Thereby, the air pressure of the sealing capsule 201i decreases, and the sealing capsule 201i shrinks into the bottom template 104, so that the bottom template 104 can be smoothly separated from other bottom templates 104. As the gas in the fixed sleeve 201a continues to increase, the piston 201c can continue to move downward. When the piston 201c moves to the inner bottom wall of the lifting sleeve 201b, the lifting sleeve 201b can be pushed downward, so that the lifting sleeve 201b moves downward. Thereby, the lifting sleeve 201b drives the pulling seat 103 to move downward, so that the pulling seat 103 drives the bottom template 104 to move downward. At this time, the concrete member still stays in place under the support of other bottom templates 104, so that this bottom template 104 is separated from the concrete member alone.
[0054] At this time, when the bottom template 104 moves downward, it will squeeze the sliding sleeve 203i below it, causing the third spring 203h in the sliding sleeve 203i to be compressed and store energy until the bottom template 104 moves to the lowest point of its stroke. During this process, the sliding sleeve 203i squeezes the extrusion block 204d, so that the extrusion block 204d drives the insertion rod 204b away from the slot 203g-1, thereby releasing the limit on the rack 203g. The rack 203g drives the adjustment gear 203c to rotate 90 degrees under the push of the third spring 203h. When the adjustment gear 203c rotates 90 degrees, the card slot 203i-1 opened on the surface of the sliding sleeve 203i drops to the end of the positioning rod 204g. Since there is high-pressure gas in the connecting channel 204e-1 to push the positioning rod 204g, the positioning rod 204g is inserted into the card slot 203i-1, thereby limiting the position of the sliding sleeve 203i. At this time, the rack 203g moves to the lowest point of its stroke, making the rack 203g unable to move anymore, thereby limiting the adjustment gear 203c, and thus limiting the reversing wheel 202c that also rotates 90 degrees. At this time, the flow channel 202c-1 connects the air guide pipe 202e and the air delivery pipe 202b, so that the high-pressure gas input from the air delivery pipe 202b is delivered to the demolding assembly 200 below the next bottom template 104 through the air guide pipe 202e, and is connected to the connecting channel 204e-1 of the support shell 204e of the next demolding assembly 200, so that the next demolding assembly 200 receives the input of high-pressure air pressure.
[0055] While one runner 202c-1 connects the air duct 202e and the air delivery pipe 202b, another runner 202c-1 connects the connecting pipe 202d and the exhaust duct 202a-1, allowing the high-pressure gas in the fixed sleeve 201a and the lifting sleeve 201b to be discharged from the exhaust duct 202a-1 through the connecting pipe 202d and the runner 202c-1, thereby reducing the air pressure in the fixed sleeve 201a and the lifting sleeve 201b. Under the restoring elastic force of the sixth spring 105c, the bottom template 104 starts to rise from the lowest point of its stroke, causing the second support sleeve 105b to move upward simultaneously. During this process, since the upward force of the sixth spring 105c on the bottom template 104 is much greater than the elastic force of the first spring 201d, the first spring 201d will not move back until the bottom template 104 has not risen to the highest point of its stroke. When the bottom template 104 fits against the bottom of the concrete member again, the continued descent of the fixed sleeve 201a and the lifting sleeve 201b causes the first spring 201d to start releasing its elastic force, thereby pushing the piston 201c. This causes the piston 201c to drive the extrusion sleeve 201f towards the sealing sleeve 201g, squeezing the gas in the extrusion sleeve 201f and the sealing sleeve 201g into the sealing bladder 201i, causing the sealing bladder 201i to expand again. This fills the gaps between the bottom template 104 and its adjacent bottom template 104, as well as the gaps between the bottom template 104 and the side template 106.
[0056] When the next demoulding assembly 200 receives an input of high-pressure gas, it starts to repeat the above process, causing the multiple bottom templates 104 of the concrete member to be separated from the concrete member in sequence, then approaching the concrete member to support it, thus completing the separation operation of the multiple bottom templates 104 from the concrete member without the concrete member moving.
[0057] The air duct 202e of the last demoulding assembly 200 delivers high-pressure gas into the airbag 205e, causing the airbag 205e to expand, thereby pushing the push plate 205d, which in turn pushes the second pull plate 205c, causing the second pull plate 205c to drive the side template 106 away from the concrete member. This allows the four side templates 106 to move away from the concrete member, completing the demoulding of the four side templates 106 from the concrete member. At this point, the input of high-pressure gas into the input pipe 204f is stopped, and the gas pressure inside the input pipe 204f enters a pressure-holding state.
[0058] When the staff sees the four side templates 106 moving away from the concrete member, it means the completion of the entire demoulding process, and at this time, the concrete member can be removed.
[0059] When the mold needs to be used again to produce concrete components, first, by disconnecting or using an exhaust valve, etc., the air pressure in the input pipe 204f is decreased, so that the air pressure in the connecting passage 204e-1 is decreased. Under the pulling force of the fifth spring 204h, the positioning rod 204g can be made to move away from the clamping groove 203i-1, thus releasing the limit on the sliding sleeve 203i, so that the rack 203g can move. Under the reset elastic force of the coil spring 203b, the reversing wheel 202c can be made to rotate reversely by 90 degrees, thus resetting. The flow passage 202c-1 makes the air guide pipe 202e communicate with the exhaust passage 202a-1, and the high-pressure gas in the air guide pipe 202e is thus discharged, so that the air pressure in the connecting passage 204e-1 in the adjacent demolding assembly 200 is decreased by the air guide pipe 202e, thus forming a chain reaction, making multiple reversing wheels 202c all reset.
[0060] After the reversing wheel 202c of the last demolding assembly 200 is reset, since the air guide pipe 202e communicates with the exhaust passage 202a-1, and since this air guide pipe 202e communicates with the airbag 205e, the airbag 205e on one side of the four side templates 106 is deflated, making the airbag 205e contract, so that under the pushing of the seventh spring 107c, the four side templates 106 are closed, so that the mold can be used again.
[0061] During the whole using process, when demolding is needed, only high-pressure gas needs to be input into the input pipe 204f. When the mold needs to be closed, by disconnecting or exhausting the input pipe 204f through an exhaust valve, etc., the air pressure in the input pipe 204f can be decreased. The operation is convenient. While protecting the concrete components, the overall production efficiency can be improved.
