Description

Technical Field

[0001] The present invention relates to the technical field of PC component production, and in particular to an assembled PC component production device and a production method. Background Art

[0002] PC is the abbreviation of precast concrete. Different from traditional cast-in-place concrete, which requires on-site mold making, on-site pouring and on-site maintenance, PC components are produced in the factory through standardized and mechanized methods, and then the standardized PC components are assembled on the construction site. Compared with cast-in-place concrete, PC components have a safer construction environment, better quality control, higher production efficiency, lower cost and reduced environmental pollution during on-site construction. They are widely used in construction, transportation, water conservancy and other fields.

[0003] At present, the factory usually produces PC components by pouring concrete into a prepared mold. After the production and pouring of the PC components are completed, they need to be left to stand for a certain period of time to allow the concrete to initially solidify. Then the solidified PC components are placed in a steam curing box to further solidify the PC components, accelerate the hydration reaction of the concrete, and enhance the strength of the PC components.

[0004] However, in this production method, during the static process, the lower surface of the PC component is in close contact with the mold surface. At this time, the upper surface of the PC component is in contact with the external air, while the lower surface is not in contact with the air. This will cause the hydration reaction rates of the upper and lower surfaces of the PC component to be different, and it will take a longer time for the PC component to completely solidify, which will reduce the solidification rate, resulting in different fixation effects on the two surfaces of the PC component, and thus different strengths on the two surfaces of the PC component, making it more likely to crack during solidification. Moreover, after the PC component solidifies, it must be sent to a steam curing box for steam curing. During this process, the template needs to be removed and the PC component that has not been completely solidified needs to be moved, which increases the production steps and reduces production efficiency. Moreover, the PC component is easily broken during the moving process. Summary of the invention

[0015] The present invention also provides a method for producing an assembled PC component, which specifically comprises the following steps:

[0016] Step 1: After pouring concrete and steel mesh into the space between the four side formworks and the first support plate and the second support plate according to the process sequence, wait for the PC component to initially solidify to form an assembled PC component plate of the required shape, and then control the steam generator to add steam to the inside of the hollow column. The steam flows into the inside of each upper steam pipe and then flows out through the nozzle. The steam covers the upper surface of the PC component on the upper side of each lower support shell, heats and cures the PC component, and accelerates the curing efficiency of the PC component.

[0017] Step 2: Control the telescopic end of the clutch cylinder of the clutch mechanism in each PC component mold device to retract, thereby driving the shift fork rod to rotate. Through the sliding connection between the pin shaft and the annular slide groove, the rotation of the shift fork rod drives the fixed ring and the sliding sleeve to move in the direction of the driven friction disc. The sliding sleeve drives the active friction disc to move synchronously, so that the active friction disc and the driven friction disc are pressed tightly. At this time, the transfer shaft and the active shaft can be rigidly connected, and then the main motor of the central driving mechanism is controlled to drive the main shaft to rotate. The main shaft drives multiple active bevel gears on its outer side to rotate. The active bevel gear rotates through the teeth to drive the driven bevel gear and the transfer shaft to rotate. The transfer shaft rotates to drive the active shaft to rotate. The active shaft drives the active gear to rotate. The active gear rotates through the teeth to drive the two driven gears to rotate in the same direction, thereby driving the two driven shafts to rotate in the same direction.

[0018] Step 3: When the two driven shafts rotate synchronously, the multiple first cams and the second cams on their outer sides can be driven to rotate synchronously respectively. Since the angles between the multiple first cams and the multiple second cams are 180 degrees, the multiple first cams and the multiple second cams press the L-shaped pull rods on both sides alternately, and the multiple first support plates and the second support plates can be driven to move down alternately for a distance through the L-shaped pull rods. When the raised ends of the first cams and the second cams are separated from one side of the L-shaped pull rod, the first support plates and the second support plates are pushed up and reset again under the elastic force of the lifting spring, thereby realizing the alternating up and down movement of the first support plates and the second support plates;

[0019] Step 4. When the multiple first support plates move downward, the upper side of the first support plates is separated from the lower surface of the PC component, and the first support plate drives the steam piston to move toward the lower end of the piston cylinder through the piston pull rod, and squeezes the steam at the lower end of the piston cylinder into the air storage cavity of the adjacent second support plate through the steam outlet pipe and the air inlet joint, and then the steam flows into the gap between the first support plate and the lower surface of the PC component through the air vent inside the second support plate. The high-temperature steam can heat and maintain the position where the lower surface of the PC component contacts the first support plate. When the multiple first support plates move down to the lowest point, they start to move up and reset, driving the multiple steam pistons to move up, so that negative pressure is formed in the space at the lower end of the piston cylinder, and the steam inside the hollow column is sucked into the air storage cavity through the docking plug, the inner steam pipe and the steam suction pipe. The lower end space inside the piston cylinder, when the first support plate moves up, the steam in the gap between it and the lower surface of the PC component can be pressed back to the inner side of the air storage chamber inside the adjacent second support plate, and then the steam inside the air storage chamber is discharged to the inner side of the lower support shell through the exhaust joint, and then discharged to the outside through the exhaust port at one end of the lower support shell. When multiple first support plates complete an up and down movement cycle, multiple second support plates also have to complete an up and down cycle. Through the above principle, when multiple second support plates move back and forth, steam can be introduced into the gap between the second support plate and the lower surface of the PC component, thereby heating and curing the position where the lower surface of the PC component contacts the second support plate, so that the upper and lower surfaces of the PC component can be heated and cured at the same time.

[0020] The present invention provides an assembly type PC component production device and a production method by improvement, which have the following improvements and advantages compared with the prior art:

[0021] First, the present invention drives the transfer shaft to rotate through the central driving mechanism, and then transmits the rotational torque of the transfer shaft to the driven friction disk of the PC component mold device through the clutch mechanism, thereby driving the two driven shafts to rotate, and realizing driving the multiple first support plates and the multiple second support plates to move up and down alternately, so that the first support plates and the second support plates are alternately separated from and contacted with the lower surface of the PC component. At the same time, through the pumping mechanism, high-temperature steam can be guided to the lower surface of the PC component, and the steam is guided to the upper surface of the PC component through the upper steam pipe, so that the upper and lower surfaces of the PC component can be heated and cured at the same time, so that the steam heat and moisture are evenly covered at various positions of the PC component, so that the hydration reaction of the concrete can be evenly carried out at various positions inside the PC component, which not only improves the curing efficiency of the PC component, but also makes the PC component more evenly heated, better avoids cracks in the PC component during curing, and has a better curing effect, thereby improving the overall strength of the PC component after curing.

[0022] Secondly, the present invention uses a PC component mold device to shape the poured concrete. Compared with the existing production process, there is no need to remove the formwork of the PC component and then move the PC component to the inside of the curing box for steam curing, which avoids the breakage of the incompletely solidified PC component during the formwork removal process.

The sliding sleeve 203 drives the active friction disc 207 to move synchronously, so that the active friction disc 207 is pressed against the driven friction disc 106. At this time, the transfer shaft 5 and the active shaft 105 can be hardened. The main motor 8 of the central driving mechanism is then controlled to run and drive the main shaft 9 to rotate, the main shaft 9 drives the multiple driving bevel gears 10 on its outer side to rotate, the driving bevel gear 10 rotates and drives the driven bevel gear 11 and the transfer shaft 5 to rotate through the teeth, the transfer shaft 5 rotates and drives the driving shaft 105 to rotate, the driving shaft 105 drives the driving gear 109 to rotate, the driving gear 109 rotates and drives the two driven gears 108 to rotate in the same direction through the teeth, thereby driving the two driven shafts 107 to rotate in the same direction;

[0060] Step 3, when the two driven rotating shafts 107 rotate synchronously, they can respectively drive the multiple first cams 110 and the second cams 111 on the outer sides to rotate synchronously. Since the angles between the multiple first cams 110 and the multiple second cams 111 are 180 degrees, the multiple first cams 110 and the multiple second cams 111 alternately press the L-shaped pull rods 112 on both sides, and the multiple first support plates 103 and the second support plates 104 can be driven to move down alternately for a distance through the L-shaped pull rods 112. When the raised ends of the first cams 110 and the second cams 111 are separated from one side of the L-shaped pull rod 112, the first support plates 103 and the second support plates 104 are pushed up and reset again under the elastic force of the lifting spring 115, thereby realizing the alternating up and down movement of the first support plates 103 and the second support plates 104;

[0061] Step 4, when the multiple first support plates 103 move downward, the upper side of the first support plates 103 is separated from the lower surface of the PC component, and the first support plate 103 drives the steam piston 124 to move toward the lower end of the piston cylinder 116 through the piston pull rod 121, and squeezes the steam at the lower end of the piston cylinder 116 into the gas storage chamber 119 of the adjacent second support plate 104 through the steam outlet pipe 126 and the air inlet joint 122, and then the steam flows into the gap between the first support plate 103 and the lower surface of the PC component through the air vent 120 inside the second support plate 104, and the high-temperature steam can heat and maintain the position where the lower surface of the PC component contacts the first support plate 103, and when the multiple first support plates 103 move down to the lowest point, they start to move up and reset, driving the multiple steam pistons 124 to move upward, so that negative pressure is formed in the space at the lower end of the piston cylinder 116, and the steam inside the hollow column 4 is discharged through the docking plug 117 and the inner steam pipe 11 8 and the steam suction pipe 125 are sucked into the lower end space inside the piston cylinder 116. At the same time, when the first support plate 103 moves upward, the steam in the gap between it and the lower surface of the PC component can be pressed back to the inner side of the gas storage chamber 119 inside the adjacent second support plate 104, and then the steam inside the gas storage chamber 119 is discharged to the inner side of the lower support shell 101 through the exhaust joint 123, and then discharged to the outside through the exhaust port at one end of the lower support shell 101. When multiple first support plates 103 complete an up and down movement cycle, multiple second support plates 104 also need to complete an up and down cycle. According to the above principle, when multiple second support plates 104 move back and forth, steam can be introduced into the gap between the second support plate 104 and the lower surface of the PC component, thereby heating and curing the position where the lower surface of the PC component contacts the second support plate 104, so that the upper and lower surfaces of the PC component can be heated and cured at the same time.

[0062] Working principle: After pouring concrete and steel mesh into the space between the four side templates 102 and the first support plate 103 and the second support plate 104 according to the process sequence, wait for the PC component to initially solidify to form an assembled PC component plate of the required shape, and then control the steam generator 12 to operate to add steam to the inside of the hollow column 4, the steam flows into the inside of each upper steam pipe 6, and then flows out through the nozzle 7, the steam covers the upper surface of the PC component on the upper side of each lower support shell 101, heats and cures the PC component, and accelerates the curing efficiency of the PC component;

[0063] The clutch cylinder 202 of each PC component mold device is controlled to retract its telescopic end, thereby driving the fork rod 201 to rotate. Through the sliding connection between the pin shaft 209 and the annular slide groove, the fork rod 201 rotates to drive the fixed ring 204 and the sliding sleeve 203 to move in the direction of the driven friction disc 106. The sliding sleeve 203 drives the active friction disc 207 to move synchronously, so that the active friction disc 207 is pressed against the driven friction disc 106. At this time, the transfer shaft 5 and the active shaft 105 can be rigidly connected. Then, the main motor 8 of the control center driving mechanism is driven to rotate the main shaft 9, and the main shaft 9 drives the multiple driving bevel gears 10 on its outer side to rotate, and the driving bevel gear 10 rotates through the teeth to drive the driven bevel gear 11 and the transfer shaft 5 to rotate, and the transfer shaft 5 rotates to drive the driving shaft 105 to rotate, and the driving shaft 105 drives the driving gear 109 to rotate, and the driving gear 109 rotates through the teeth to drive the two driven gears 108 to rotate in the same direction, thereby driving the two driven shafts 107 to rotate in the same direction;

[0064] When the two driven rotating shafts 107 rotate synchronously, they can respectively drive the multiple first cams 110 and the second cams 111 on the outer sides thereof to rotate synchronously. Since the angles between the multiple first cams 110 and the multiple second cams 111 are 180°, the multiple first cams 110 and the multiple second cams 111 alternately press the L-shaped pull rods 112 on both sides, and the multiple first support plates 103 and the second support plates 104 can be driven to move down alternately for a distance through the L-shaped pull rods 112. When the raised ends of the first cams 110 and the second cams 111 are separated from one side of the L-shaped pull rod 112, the first support plates 103 and the second support plates 104 are pushed up and reset again under the elastic force of the lifting spring 115, thereby realizing the alternating up and down movement of the first support plates 103 and the second support plates 104.

[0065] When the plurality of first support plates 103 move downward, the upper side of the first support plates 103 is separated from the lower surface of the PC component, and the first support plate 103 drives the steam piston 124 to move toward the lower end of the piston cylinder 116 through the piston pull rod 121, and squeezes the steam at the lower end of the piston cylinder 116 into the gas storage cavity 119 of the adjacent second support plate 104 through the steam outlet pipe 126 and the air inlet joint 122, and then the steam flows into the gap between the first support plate 103 and the lower surface of the PC component through the vent 120 inside the second support plate 104, and the high-temperature steam can heat the lower surface of the PC component and the first support plate 104. 03 contact position for heating and curing, when the multiple first support plates 103 move down to the lowest point and then start to move up and reset, driving the multiple steam pistons 124 to move up, so that the lower end space of the piston cylinder 116 forms a negative pressure, and the steam inside the hollow column 4 is sucked into the lower end space inside the piston cylinder 116 through the docking plug 117, the inner steam pipe 118 and the steam suction pipe 125. At the same time, when the first support plate 103 moves up, the steam in the gap between it and the lower surface of the PC component can be pressed back to the inner side of the gas storage chamber 119 inside the adjacent second support plate 104, and then the steam inside the gas storage chamber 119 is discharged through the exhaust pipe 117. The air is discharged from the air joint 123 to the inner side of the lower support shell 101, and then discharged to the outside through the exhaust port at one end of the lower support shell 101. When the plurality of first support plates 103 complete a cycle of moving up and down, the plurality of second support plates 104 also need to complete a cycle of moving up and down. According to the above principle, when the plurality of second support plates 104 move back and forth, the steam can be introduced into the gap between the second support plates 104 and the lower surface of the PC component, so as to heat and maintain the position where the lower surface of the PC component contacts the second support plates 104, so that the upper and lower surfaces of the PC component can be heated and maintained at the same time. The steam heat and moisture are evenly covered at various positions of the PC component, so that the hydration reaction of the concrete can be carried out evenly at various positions inside the PC component, which not only improves the curing efficiency of the PC component, but also makes the PC component more evenly heated, better avoids cracks in the PC component during curing, and has a better curing effect, thereby improving the overall strength of the PC component after curing. At the same time, compared with the existing production process, there is no need to remove the formwork of the PC component and then move the PC component to the inside of the curing box for steam curing, which avoids the breakage of the PC component that is not completely solidified during the process of removing the formwork;

[0066] The cross plate 301 and the roller shaft 302 facilitate loading and unloading of the lower support shell 101 poured with concrete. At the same time, the telescopic end of the locking cylinder 306 is extended and retracted to drive the rocker arm 305, the locking shaft 303 and the locking claw 304 to rotate, so that the locking claw 304 is rotated to a vertical angle and pressed on one end of the lower support shell 101, so that the lower support shell 101 can be positioned, so that the inner steam pipe 118 is inserted into the inner side of the docking plug 117, and the driven friction disc 106 and the active friction disc 207 are aligned, so that the steam inside the hollow column 4 can enter the inner side of the inner steam pipe 118, and then flow to the lower surface of the PC component through the air storage cavity 119 and the vent 120, so as to heat and maintain the lower surface of the PC component;

[0067] By sliding the locking pin 129 and inserting it into the inner side of the second fixing block 128, the side formwork 102 can be kept at a vertical angle, so that the concrete inside can be better formed. When the side formwork 102 needs to be separated from the formed PC component, it is only necessary to pull out the locking pin 129 and then rotate the side formwork 102 to quickly separate the side formwork 102 from the PC component. The operation is simple and the formed PC component is not likely to be cracked.

The method for producing an assembled PC component according to claim 1, characterized in that: The specific steps include: Step 1: After pouring concrete and steel mesh into the space between the four side formworks (102) and the first support plate (103) and the second support plate (104) according to the process sequence, wait for the PC component to initially solidify to form an assembled PC component plate of a desired shape, then control the steam generator (12) to operate to replenish steam into the inner side of the hollow column (4), the steam flows into the inner side of each upper steam pipe (6), and then flows out through the nozzle (7), the steam covers the upper surface of the PC component on the upper side of each lower support shell (101), heats and cures the PC component, and accelerates the curing efficiency of the PC component; Step 2: Control the telescopic end of the clutch cylinder (202) of the clutch mechanism in each PC component mold device to retract, thereby driving the fork rod (201) to rotate. Through the sliding connection between the pin shaft (209) and the annular slide groove, the fork rod (201) rotates to drive the fixed ring (204) and the sliding sleeve (203) to move in the direction of the driven friction disk (106). The sliding sleeve (203) drives the active friction disk (207) to move synchronously, so that the active friction disk (207) and the driven friction disk (106) are pressed tightly. At this time, the transfer shaft (5) and the active shaft (105) can be rigidly connected. The main motor (8) of the central driving mechanism is then controlled to run and drive the main rotating shaft (9) to rotate. The main rotating shaft (9) drives a plurality of driving bevel gears (10) on its outer side to rotate. The driving bevel gear (10) rotates and drives the driven bevel gear (11) and the transfer rotating shaft (5) to rotate through the teeth. The transfer rotating shaft (5) rotates and drives the driving rotating shaft (105) to rotate. The driving rotating shaft (105) drives the driving gear (109) to rotate. The driving gear (109) rotates and drives the two driven gears (108) to rotate in the same direction through the teeth, thereby driving the two driven rotating shafts (107) to rotate in the same direction. Step 3: When the two driven rotating shafts (107) rotate synchronously, they can respectively drive the multiple first cams (110) and the second cams (111) on the outer sides thereof to rotate synchronously. Since the angles between the multiple first cams (110) and the multiple second cams (111) are all 180 degrees, the multiple first cams (110) and the multiple second cams (111) alternately press the L-shaped pull rods (112) on both sides, and the multiple first support plates (103) and the second support plates (104) can be driven to alternately move downward for a certain distance through the L-shaped pull rods (112). When the raised ends of the first cams (110) and the second cams (111) are separated from one side of the L-shaped pull rod (112), the first support plates (103) and the second support plates (104) are pushed upward and reset again under the elastic force of the lifting spring (115), thereby realizing the alternating up and down movement of the first support plates (103) and the second support plates (104); Step 4: When the plurality of first support plates (103) move downward, the upper side of the first support plates (103) is separated from the lower surface of the PC component, and the first support plates (103) drive the steam piston (124) to move toward the lower end of the piston cylinder (116) through the piston pull rod (121), and squeeze the steam at the lower end of the piston cylinder (116) into the gas storage chamber (119) of the adjacent second support plates (104) through the steam outlet pipe (126) and the gas inlet joint (122), and then the steam is discharged through the second support plates. The vent (120) inside the plate (104) flows into the gap between the first support plate (103) and the lower surface of the PC component, and the high-temperature steam can heat and maintain the contact position between the lower surface of the PC component and the first support plate (103). When the plurality of first support plates (103) move down to the lowest point, they start to move up and reset, driving the plurality of steam pistons (124) to move up, so that negative pressure is formed in the space at the lower end of the piston cylinder (116), and the steam inside the hollow column (4) is discharged through the docking plug (117), the inner The steam pipe (118) and the steam suction pipe (125) are sucked into the lower end space inside the piston cylinder (116). At the same time, when the first support plate (103) moves upward, the steam in the gap between it and the lower surface of the PC component can be pressed back to the inner side of the gas storage chamber (119) inside the adjacent second support plate (104). Then, the steam inside the gas storage chamber (119) is discharged to the inner side of the lower support shell (101) through the exhaust joint (123), and then discharged to the outside through the exhaust port at one end of the lower support shell (101). When the plurality of first support plates (103) completes one up-and-down movement cycle, the plurality of second support plates (104) also complete one up-and-down cycle. According to the above principle, when the plurality of second support plates (104) reciprocate, the steam can be introduced into the gap between the second support plates (104) and the lower surface of the PC component, thereby heating and curing the position where the lower surface of the PC component contacts the second support plates (104), thereby simultaneously heating and curing the upper and lower surfaces of the PC component.
