Description

Technical Field

[0001] The invention relates to the technical field of workpiece maintenance, and in particular to a processing and maintenance device and method for prefabricated concrete parts. Background Art

[0002] The maintenance of precast concrete parts refers to the process of maintaining suitable hydration conditions of precast concrete parts by controlling environmental factors such as humidity and temperature, ensuring the normal development of the strength of precast concrete parts and preventing cracks or other defects. During the maintenance process, workers usually spray curing liquid on the surface of precast concrete parts. When spraying, in order to make the curing liquid spray more evenly, workers often place precast concrete parts on conveyor rollers with as large an interval as possible for the first spraying of curing liquid, and then move the precast parts a certain distance to expose the part of the precast parts blocked by the conveyor rollers, and then the workers spray the precast parts a second time to achieve a more comprehensive spraying effect.

[0003] After the prefabricated parts have been placed for a long time, some impurities are easily accumulated on the top and the inclined surfaces on both sides of the upper part of the prefabricated parts. When the current curing device is used to cure the concrete prefabricated parts, it is not convenient to brush off the impurities accumulated on the prefabricated parts before spraying the curing liquid, which makes it difficult for the sprayed curing liquid to fully contact with the surface of the prefabricated parts, and it takes a certain amount of time for the prefabricated parts to absorb the curing liquid. At the same time, the curing liquid is easy to evaporate in an exposed environment. The existing curing device is not convenient for moisturizing and heat-insulating the surface of the prefabricated parts by spreading wet sand immediately after spraying the curing liquid, which makes it difficult for the prefabricated parts to fully absorb the curing liquid, resulting in poor curing effect on the prefabricated parts. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings, the present invention provides a processing and curing device and method for concrete precast parts, which can brush off impurities before spraying to ensure that the curing liquid and the precast parts are in more complete contact, and can also keep the precast parts moisturized and heat-insulated so that they can more fully absorb the curing liquid, thereby enhancing the curing effect on the precast parts.

[0014] A curing method for a processing and curing device for a precast concrete part comprises the following steps:

[0015] S1: Before feeding the prefabricated parts, the staff first connects the curing liquid to the water inlet of the water pump through a pipe, and pours the prepared wet sand from the inlet of the maintenance box. Then the staff places the prefabricated parts on the support seat close to the servo motor. Several support rollers on the support seat will support the bottom of the prefabricated parts, thereby completing the preparation before curing;

[0016] S2: When the preform needs to be fed, the staff first pushes the placed preform into the inner part of the outer frame for a certain distance to contact with several conveying rollers, and then controls the servo motor to move the preform to a preset position inside the outer frame through the conveying rollers. Then the staff controls the output shaft of the servo motor to stop rotating, and the preform stops moving, thereby completing the feeding;

[0017] S3: When the prefabricated parts need to be sprayed for maintenance, the staff starts the water pump and energizes the two electric slide rails at the same time. The electric slide rail drives the electric slider to move so that the maintenance liquid is gradually sprayed on the exposed surface of the prefabricated parts. The rack one drives the conveying roller to rotate in the opposite direction through the gear one, driving the prefabricated parts to move in the opposite direction for a certain distance to expose the obscured bottom surface. Then the electric slide rail drives the electric slider to move in the opposite direction to spray the maintenance liquid on the surface of the prefabricated parts again. While spraying the prefabricated parts with the maintenance liquid, the reciprocating swing of the arc-shaped brush rack and the reciprocating movement of the horizontal brush rod will repeatedly brush off the impurities accumulated on the top and upper sides of the prefabricated parts. The movement of the sliding block drives the maintenance box to move. The extrusion rod squeezes the maintenance box downward so that the gear two is meshed with the rack two. The reciprocating movement of the rack two passes through the gear two to cause the rotating plate to swing back and forth, thereby continuously spreading the wet sand on the top and upper sides of the prefabricated parts for moisturizing and heat preservation.

[0018] S4: After the maintenance is completed, the staff will cut off the power to the electric slide rail and turn off the water pump. Then the staff will control the servo motor again to move the prefabricated part out from the other side of the outer frame through the conveyor roller. The moved prefabricated part will move to another support seat. Several support rollers on the other support seat will support the prefabricated part after maintenance. Then the staff can take out the prefabricated part after maintenance.

[0019] The present invention has the following advantages: the present invention drives the electric slider through the electric slide rail to drive the rack 1, the spray rack and the spray head to move together, and then the continuously sprayed mist curing liquid is gradually sprayed on the exposed surface of the prefabricated part, thereby curing the surface of the prefabricated part; the movement of the rack 1 drives the gear 1 to rotate a certain angle, and then the prefabricated part is driven to move in the opposite direction a certain distance through the transmission component and a plurality of conveying rollers to expose the obstructed part of the bottom surface; in this way, by spraying the prefabricated part for the second time, the obstructed bottom surface of the prefabricated part can be exposed and sprayed with the curing liquid, thereby making the spraying of the surface of the prefabricated part more sufficient, thereby enhancing the curing effect of the prefabricated part.

One of the transmission wheels on the same transmission assembly 301 is connected to one end of the conveying roller 103 on one side through a flat key, and the other transmission wheel on the same transmission assembly 301 is connected to the output shaft of the servo motor 3 on the same side through a flat key. A flat belt is wound between the two transmission wheels on the same transmission assembly 301.

[0041] The transmission component 302 is composed of a plurality of sprockets and a chain. The plurality of sprockets on the same transmission component 302 are respectively connected to the same side of a plurality of conveying rollers 103 through flat keys, and a chain is wound between the plurality of sprockets on the same transmission component 302.

[0042] The spraying mechanism includes an electric slide rail 41, an electric slider 42, a spraying frame 43, a spraying head 44, a sliding block 45 and a water pump 46. The two electric slide rails 41 are respectively mounted on the two support frames 102. The two electric slide rails 41 are slidably connected with the electric sliders 42. A spraying frame 43 is installed between the two electric sliders 42. The spraying frame 43 is slidably connected to the slide grooves 1021 of the two support frames 102. A cavity is opened in the spraying frame 43. Both sides of the upper part of the spraying frame 43 are opened with transverse grooves 431. A plurality of spray heads 44 are connected to the inner side of the spray rack 43, and the direction of the plurality of spray heads 44 is consistent with the direction of the side of the prefabricated part 2. The spray heads 44 are used to spray the curing liquid, and a plurality of atomizing holes are opened on the spray heads 44. The atomizing holes on the spray heads 44 are used to atomize the sprayed curing liquid. A sliding block 45 is welded to the top of the spray rack 43, and the sliding block 45 is slidably connected to the square opening of the outer frame 1. A water pump 46 is installed on the sliding block 45, and the water outlet of the water pump 46 is connected to the top of the spray rack 43.

[0043] The switching mechanism includes a rack 51, an overrunning clutch 52 and a gear 53. The two racks 51 are respectively installed on both sides of the bottom of the spray frame 43. Both ends of the conveying roller 103 located on the side away from the servo motor 3 are connected to the overrunning clutch 52 through a keyway, and the outer sides of the two overrunning clutches 52 are connected to the gear 53 through a flat key.

[0044] It also includes a supporting mechanism, which is arranged on the outer frame 1. The supporting mechanism is used to support when pushing in and out the preform 2. The supporting mechanism includes a supporting seat 81 and a supporting roller 82. The two supporting seats 81 are respectively welded on both sides of the outer frame 1. A plurality of supporting rollers 82 are rotatably connected to the two supporting seats 81. The plurality of supporting rollers 82 and the plurality of conveying rollers 103 are on the same horizontal plane. The supporting rollers 82 are used to support the preform 2 while better moving the preform 2.

[0045] First, the staff connects the curing liquid to the water inlet of the water pump 46 through a pipeline. Before feeding the preform 2, the staff first places the preform 2 on the support seat 81 close to the side of the servo motor 3. Several support rollers 82 on the support seat 81 will support the bottom of the preform 2. Under the action of the support rollers 82, the preform 2 is easier to move, which is convenient for the staff to feed the preform 2 later. When it is necessary to feed the preform 2, the staff pushes the preform 2 placed on the support seat 81 into the inner part of the outer frame 1 for a distance. After the preform 2 moves, it will contact several of the conveying rollers 103. Then the staff controls the output shafts of the two servo motors 3 to rotate. The output shafts of the two servo motors 3 rotate and drive one of the conveying rollers 103 to rotate through the two transmission components 301. The rotation of one of the conveying rollers 103 drives the remaining conveying rollers 103 to rotate synchronously through the transmission component 302. The rotation of the conveying rollers 103 will drive the preform 2 to move further into the inner part of the outer frame 1 until After the preform 2 completely enters the outer frame 1 and deviates to the side away from the servo motor 3, the staff controls the output shaft of the servo motor 3 to stop rotating, so that the preform 2 no longer moves, and at the same time, a number of conveyor rollers 103 will evenly cover part of the bottom surface of the preform 2 at intervals; when the preform 2 needs to be sprayed for curing, the staff starts the water pump 46 and energizes the two electric slide rails 41 at the same time, and the water pump 46 will draw the curing liquid into the spray rack 43, and the curing liquid in the spray rack 43 will continue to flow. The spraying head 44 sprays the mist, and the electric slide rail 41 is energized to drive the two electric sliders 42 to move away from the servo motor 3. The movement of the two electric sliders 42 drives the rack 51, the spraying rack 43, the spraying head 44, the sliding block 45 and the water pump 46 to move away from the servo motor 3. The movement of the spraying rack 43 and the spraying head 44 will gradually spray the continuously sprayed mist curing liquid on the exposed surface of the preform 2. In this way, the surface of the preform 2 can be cured by spraying the curing liquid.

[0046] When the spray rack 43 and the spray head 44 move to the other side of the preform 2, the rack 51 will mesh with the gear 53, and then the rack 51 will continue to move to drive the gear 53 to rotate a certain angle. The rotation of the gear 53 will drive one of the conveying rollers 103 to rotate in the opposite direction by a certain angle through the overrunning clutch 52, and then drive several conveying rollers 103 to rotate in the opposite direction by a certain angle through the transmission component 302. The reverse rotation of several conveying rollers 103 at a certain angle will drive the preform 2 to move in the opposite direction by a certain distance, so that the preform 2 is blocked. The electric slide rail 41 then drives the two electric sliders 42 to move in the opposite direction, thereby causing the rack 1 51, the spray rack 43 and the spray head 44 to move in the opposite direction together. The spray rack 43 and the spray head 44 move in the opposite direction together to spray the curing liquid on the surface of the preform 2 again. The spray heads 44 at the bottom spray the sprayed curing liquid on the bottom surface of the preform 2 that was not exposed before. The reverse movement of the rack 1 51 drives the gear 1 53 to rotate in the opposite direction. Under the action of the overrunning clutch 52, the gear 1 53 rotates idly without driving the transmission The conveying roller 103 rotates, so that the bottom surface of the preform 2 that is blocked can be exposed and sprayed with the curing liquid while the preform 2 is sprayed twice, so that the surface of the preform 2 can be sprayed more fully, thereby enhancing the curing effect of the preform 2; after the curing is completed, the staff will cut off the power of the electric slide rail 41 and turn off the water pump 46, and the spray head 44 will no longer spray the curing liquid. Then the staff will control the output shafts of the two servo motors 3 to rotate again, so that the several conveying rollers 103 continue to rotate to move the preform 2 out from the other side of the outer frame 1 , the removed prefabricated part 2 will move to another support seat 81, and several support rollers 82 on the other support seat 81 will support the cured prefabricated part 2. In this way, before feeding and after discharging, the two support seats 81 and several support rollers 82 will support the prefabricated part 2 in turn, thereby facilitating the staff to feed and discharge the prefabricated part 2, thereby improving the curing efficiency; after the discharging is completed, the staff can take out the cured prefabricated part 2, and at the same time, the staff can remove the two inspection panels 101 from the outer frame 1 according to the situation to inspect the inside of the outer frame 1.

[0047] Embodiment 2: Based on embodiment 1, Figure 10-13As shown, it also includes a cleaning mechanism, which is arranged on the spray frame 43. The cleaning mechanism is used to clean impurities accumulated on the upper surface of the preform 2. The cleaning mechanism includes a limit column 61, a sliding sleeve 62, an arc brush frame 63, a limit block 64, a sliding frame 65 and a transverse brush rod 66. The two limit columns 61 are respectively welded to the inner upper part of the outer frame 1 on both sides. Two wave-shaped extrusion grooves are opened on the two limit columns 61. The two wave-shaped extrusion grooves on the same limit column 61 are symmetrically arranged. The wave-shaped extrusion grooves on the same side of the two limit columns 61 are arranged in a symmetrical manner. The wavy extrusion grooves are arranged in the same direction, and a sliding sleeve 62 is sleeved on each of the two limiting columns 61. Small protrusions are arranged on both sides of the inner walls of the two sliding sleeves 62. The four small protrusions on the two sliding sleeves 62 are respectively located in the four wavy extrusion grooves of the two limiting columns 61. The wavy extrusion grooves of the limiting columns 61 are used to squeeze the small protrusions of the sliding sleeves 62 so that the sliding sleeves 62 reciprocate. The outer sides of the two sliding sleeves 62 are rotatably connected to the two sides of the spraying frame 43 respectively. The outer sides of the two sliding sleeves 62 are welded with arc-shaped brush holders 63. There are four arc-shaped brush racks 63 in total. Two arc-shaped brush racks 63 on the same sliding sleeve 62 form a group. The two groups of arc-shaped brush racks 63 are symmetrically arranged. The two arc-shaped brush racks 63 in the same group are symmetrically arranged on both sides of the spraying rack 43. The arc-shaped brush racks 63 are used to repeatedly brush off the impurities accumulated on both sides of the upper part of the preform 2. Two limit blocks 64 are welded on the sides of the two groups of arc-shaped brush racks 63 close to each other. There are four limit blocks 64 in total. The limit blocks 64 are provided with arc-shaped grooves. The four limit blocks 64 are respectively located on the four arc-shaped brush racks 63 and are located on the same Two limit blocks 64 on the side and not on the same group of arc-shaped brush frames 63 form a group. There are two groups of limit blocks 64 in total. The two limit blocks 64 in the same group are symmetrically arranged. A sliding frame 65 is slidably connected between the two transverse grooves 431. Transverse brush rods 66 are welded on both sides of the sliding frame 65. The transverse brush rods 66 are used to repeatedly brush off impurities accumulated on the top of the preform 2. The two transverse brush rods 66 are respectively slidably connected to the arc-shaped grooves of the two groups of limit blocks 64. The arc-shaped grooves of the limit blocks 64 are used to squeeze and pull the transverse brush rods 66 to move back and forth.

[0048] While spraying the curing liquid on the preform 2, the movement of the spray rack 43 will drive the sliding sleeve 62, the arc-shaped brush rack 63, the sliding rack 65 and the transverse brush rod 66 to move together. The arc-shaped brush rack 63 will move to contact the two side surfaces of the upper part of the preform 2, and the transverse brush rod 66 will move to contact the top surface of the preform 2. The small protrusion in the sliding sleeve 62 will swing back and forth along the wavy extrusion groove on the limiting column 61, so that the two sliding sleeves 62 respectively drive the four arc-shaped brush racks 63 to swing back and forth in the same direction, and then drive the four limiting blocks 64 to swing back and forth in the same direction. The arc grooves of the two limiting blocks 64 on one side will squeeze the two transverse brush rods 66, and the arc grooves of the two limiting blocks 64 on the other side will pull the two transverse brush rods 6 6, thereby making the transverse brush rod 66 move to one side through the sliding frame 65 along the transverse groove 431, and then the arc grooves of the four limit blocks 64 will reversely squeeze and pull the arc brush rod to move to the other side through the sliding frame 65 along the transverse groove 431, and repeat this process. The reciprocating swing of the four limit blocks 64 in the same direction will drive the transverse brush rod 66 to move reciprocatingly horizontally by squeezing and pulling. In this way, the reciprocating swing of the four arc brush frames 63 will repeatedly brush off the impurities accumulated on the two upper side surfaces of the preform 2, and at the same time, the reciprocating movement of the transverse brush rod 66 will repeatedly brush off the impurities accumulated on the top of the preform 2, so that the curing liquid sprayed later can fully contact with the surface of the preform 2, thereby further enhancing the curing effect on the preform 2.

[0049] Embodiment 3: Based on embodiment 2, Figure 14-17As shown, a maintenance mechanism is also included, which is arranged on the sliding block 45. The maintenance mechanism is used to spread wet sand on the upper surface of the prefabricated part 2 after spraying. The maintenance mechanism includes an extrusion rod 71, a maintenance box 72, a return spring 73, a rotating plate 74, a crank 75, a synchronization rod 76 and a gear 2 77. The two extrusion rods 71 ​​are respectively welded to the inner top sides of the outer frame 1. Both sides of the extrusion rod 71 are provided with inclined surfaces. The sliding block 45 is slidably connected with a maintenance box 72. The maintenance box 72 is hollow. The top of the maintenance box 72 is provided with a feed inlet. The feed inlet of the maintenance box 72 is used to put wet sand. The bottom of the maintenance box 72 is provided with a discharge port. Both sides of the maintenance box 72 are provided with columnar protrusions. The columnar protrusions of the maintenance box 72 are used to make the maintenance box 72 move up and down through the inclined surface of the extrusion rod 71. The maintenance box 72 is movable in a direction of rotation, and the movable frame 72 is provided with a plurality of movable plates 74 disposed on the top of the maintenance box 72. The movable plates 74 are provided with a plurality of movable plates 75 disposed on the bottom of the maintenance box 72. The movable plates 74 are provided with a plurality of movable plates 75 disposed on the bottom of the maintenance box 72. The movable plates 74 are provided with a plurality of movable plates 75 disposed on the bottom of the maintenance box 72. The movable plates 74 are provided with a plurality of movable plates 75 disposed on the bottom of the maintenance box 72.

[0050] It also includes a baffle 9 , which are respectively welded to the two support frames 102 , and the two baffles 9 respectively block the tops of the two transmission components 302 . The baffle 9 is used to block the wet sand left over the transmission components 302 .

[0051] Before curing the preform 2, the staff first pours the prepared wet sand into the maintenance box 72 from the feeding port, and one of the horizontal brush rods 66 moves back and forth horizontally to drive the rack 2 78 to move back and forth horizontally. When the preform 2 is sprayed for the first time, the movement of the sliding block 45 drives the maintenance box 72 to move to one side, and the columnar protrusion of the maintenance box 72 contacts one of the inclined surfaces of the squeezing rod 71, and one of the inclined surfaces of the squeezing rod 71 squeezes the columnar protrusion of the maintenance box 72 to move the maintenance box 72 upward, and the reset spring 73 is stretched. After the maintenance box 72 moves to the other side of the preform 2, the squeezing rod 71 no longer squeezes the maintenance box 72. The columnar protrusion of the box 72 is reset, and the reset spring 73 resets and drives the maintenance box 72 to reset; when the preform 2 is sprayed for the second time, the sliding block 45 moves in the opposite direction to drive the maintenance box 72 to move in the opposite direction, and the columnar protrusion of the maintenance box 72 will contact the other inclined surface of the extrusion rod 71, and the other inclined surface of the extrusion rod 71 will squeeze the columnar protrusion of the maintenance box 72 to make the maintenance box 72 move downward, and the reset spring 73 is compressed. The downward movement of the maintenance box 72 will drive the rotating plate 74 and the gear 2 77 to move downward together, and the gear 2 77 moves downward to mesh with the reciprocating rack 2 78, and the reciprocating rack 2 78 will drive the gear 2 7 7 reciprocates, the reciprocating swing of gear 2 77 will drive one of the rotating plates 74 to reciprocate, and the reciprocating swing of one of the rotating plates 74 will drive the remaining rotating plates 74 to reciprocate through the crank 75 and the synchronous rod 76. The reciprocating swing of the rotating plate 74 will intermittently open the discharge port of the maintenance box 72 and repeatedly move the wet sand in the maintenance box 72, so that the wet sand can be discharged from the maintenance box 72 more smoothly. The discharged wet sand will continue to be spread on the top surface and the two sides of the upper part of the prefabricated part 2 after the second spraying of the curing liquid. At the same time, the baffle 9 will block the wet sand that falls out, so as to ensure the stability of the transmission component 302. In this way, the surface of the preform 2 is moisturized and heat-insulated by wet sand, so that the preform 2 can absorb the curing liquid more fully, thereby making the curing of the preform 2 more effective. After the maintenance box 72 moves to the initial position, the rack 2 78 returns to the initial position and drives the gear 2 77 to rotate to the initial position, so that the plurality of rotating plates 74 cover the discharge port of the maintenance box 72 again, so that the maintenance box 72 no longer spreads wet sand, and at the same time, the squeezing rod 71 no longer squeezes the columnar protrusion of the maintenance box 72, and the reset spring 73 resets to drive the maintenance box 72 to reset, so that the gear 2 77 resets upward and disengages from the rack 2 78.
