Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of workpiece curing, in particular to a processing and curing device and method for concrete prefabricated parts. BACKGROUND

[0002] The curing of a concrete prefabricated part refers to a process of maintaining the appropriate hydration conditions of the concrete prefabricated part by controlling environmental factors such as humidity and temperature, ensuring the normal development of the strength of the concrete prefabricated part and preventing cracks or other defects. During the curing process, the surface of the concrete prefabricated part is usually sprayed with curing liquid by the staff. In order to make the spraying of the curing liquid more uniform, the staff often places the concrete prefabricated part on the conveying roller with the largest possible spacing for the first spraying of the curing liquid, then moves the prefabricated part by a certain distance so that the part covered by the conveying roller is exposed, and then the staff sprays the prefabricated part for the second time to achieve a more comprehensive spraying effect.

[0003] Because the top and the inclined surfaces on both sides of the upper part of the prefabricated part are prone to accumulate some impurities after being placed for a long time, the current curing device is not convenient for brushing off the impurities accumulated on the prefabricated part before spraying the curing liquid, which makes it difficult for the curing liquid to fully contact the surface of the prefabricated part. In addition, the prefabricated part needs a certain amount of time to absorb the curing liquid, and the curing liquid is prone to evaporate in the exposed environment. The existing curing device is not convenient for spreading wet sand on the surface of the prefabricated part for moisturizing and heat preservation immediately after the curing liquid is sprayed, which makes it difficult for the prefabricated part to fully absorb the curing liquid, resulting in poor curing effect on the prefabricated part.

[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 into the inlet of the maintenance box. Then the staff places the prefabricated parts on the support base near the servo motor. Several support rollers on the support base will support the bottom of the prefabricated parts, thus 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 distance so that it contacts several conveyor rollers. Then the staff controls the servo motor to move the preform to a preset position inside the outer frame via the conveyor rollers. The staff then controls the output shaft of the servo motor to stop rotating, and the preform stops moving, thus completing the feeding process.

[0017] S3: When the prefabricated parts need to be sprayed and cured, the staff starts the water pump and energizes the two electric slide rails at the same time. The electric slide rails drive the electric slider to move so that the curing liquid is gradually sprayed on the exposed surface of the prefabricated parts. The rack one drives the conveyor 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 curing liquid on the surface of the prefabricated parts again. While the prefabricated parts are being sprayed with the curing liquid, the reciprocating swing of the arc-shaped brush holder 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 movement of the maintenance box. The extrusion rod squeezes the maintenance box downward so that the gear two meshes 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 prefabricated part will be moved to another support seat. Several support rollers on the other support seat will support the cured prefabricated part. Then the staff can take out the cured prefabricated part.

[0019] The present application has the following advantages: the present application drives the rack I, the spraying frame and the spraying head to move together through the electric sliding rail driving the electric sliding block, and then the continuously sprayed mist-shaped maintenance liquid is gradually sprayed on the exposed surface of the prefabricated part, and then the surface of the prefabricated part is maintained, the rack I drives the gear I to rotate by a certain angle, and then the prefabricated part is driven to move reversely by a certain distance to expose the blocked bottom surface through the transmission assembly and the plurality of conveying rollers, in this way, the bottom surface of the prefabricated part is exposed and sprayed with the maintenance liquid while the prefabricated part is sprayed twice, and then the prefabricated part is sprayed more fully, thereby enhancing the maintenance effect on the prefabricated part.

[0045] Firstly, the staff will maintenance liquid through the pipeline communication on the water inlet of water pump 46, before feeding the prefabricated part 2, the staff first puts the prefabricated part 2 on the support seat 81 close to servo motor 3 side, several support rollers 82 on the support seat 81 can support the bottom of the prefabricated part 2, under the action of support roller 82, the prefabricated part 2 is more easily moved, and then facilitate the staff to feed the prefabricated part 2 subsequently; When the prefabricated part 2 needs to be fed, the staff pushes the prefabricated part 2 placed on the support seat 81 into the inside of the outer frame 1 a distance, the prefabricated part 2 moves and contacts several conveying rollers 103, then the staff controls the output shaft rotation of two servo motors 3, the output shaft rotation of two servo motors 3 drives one of the conveying rollers 103 to rotate through two transmission assemblies 301, one of the conveying rollers 103 rotates through the transmission assembly 302 to drive the remaining several conveying rollers 103 to rotate synchronously, the conveying roller 103 rotates to drive the prefabricated part 2 to move further into the inside of the outer frame 1, until the prefabricated part 2 completely enters the inside of the outer frame 1 and deviates from the side of the servo motor 3, the staff controls the output shaft of the servo motor 3 to stop rotating, so that the prefabricated part 2 does not move anymore, and several conveying rollers 103 uniformly interval type shield part of the bottom surface of the prefabricated part 2; When the prefabricated part 2 needs to be sprayed and maintained, the staff starts the water pump 46, and the two electric sliding rails 41 are electrified, the water pump 46 will draw and pump the maintenance liquid into the inside of the spraying frame 43, the maintenance liquid in the inside of the spraying frame 43 will continuously spray mist through several spraying heads 44, the electric sliding rails 41 are electrified to drive two electric sliding blocks 42 to move away from the direction of the servo motor 3, two electric sliding blocks 42 move to drive rack one 51, spraying frame 43, spraying head 44, sliding block 45 and water pump 46 to move away from the direction of the servo motor 3, spraying frame 43 and spraying head 44 move to gradually spray the continuously sprayed mist maintenance liquid on the exposed surface of the prefabricated part 2, in this way, the surface of the prefabricated part 2 can be maintained by spraying maintenance liquid;

[0046] When the spraying frame 43 and the spraying head 44 move to the other side of the preform 2, the rack one 51 is engaged with the gear one 53 at this time, and then the rack one 51 continues to move to drive the gear one 53 to rotate by a certain angle, the rotation of the gear one 53 drives one of the conveying rollers 103 to rotate reversely by a certain angle through the overrunning clutch 52, and then drives a plurality of conveying rollers 103 to rotate reversely by a certain angle through the transmission assembly 302, and the rotation of the plurality of conveying rollers 103 by a certain angle drives the preform 2 to move reversely by a certain distance, so as to expose the part of the bottom surface of the preform 2 that is blocked, and then the electric sliding rail 41 drives the two electric sliding blocks 42 to move reversely, so as to drive the rack one 51, the spraying frame 43 and the spraying head 44 to move reversely together, the spraying frame 43 and the spraying head 44 move reversely together to spray the curing liquid on the surface of the preform 2 again, and the plurality of spraying heads 44 located at the bottom spray the curing liquid on the part of the bottom surface of the preform 2 that is not exposed before, and the rack one 51 moves reversely to drive the gear one 53 to rotate reversely, and the gear one 53 does not drive the conveying roller 103 to rotate under the action of the overrunning clutch 52. Thus, the preform 2 is sprayed twice to expose the blocked bottom surface and spray the curing liquid thereon, so that the preform 2 is sprayed more fully, thereby enhancing the curing effect on the preform 2. After the curing is completed, the worker disconnects the electric sliding rail 41 and turns off the water pump 46, and the spraying head 44 no longer sprays the curing liquid, and then the worker controls the output shaft of the two servo motors 3 to rotate again, so as to drive the plurality of conveying rollers 103 to continuously rotate to move the preform 2 out of the other side of the outer frame 1, and the preform 2 moved out is moved to the other support seat 81, and the plurality of supporting rollers 82 on the other support seat 81 support the preform 2 after curing.

Figures 10-13The cleaning mechanism is arranged on the spraying frame 43, and is used for cleaning impurities accumulated on the upper surface of the prefabricated part 2. The cleaning mechanism comprises two limiting columns 61, two sliding sleeves 62, four arc-shaped brush frames 63, four limiting blocks 64, a sliding frame 65 and two transverse brush rods 66. The two limiting columns 61 are respectively welded on the inner upper portions of the two sides of the outer frame 1. Two wave-shaped extrusion grooves are formed in each of the two limiting columns 61. The two wave-shaped extrusion grooves in the same limiting column 61 are symmetrically arranged. The wave-shaped extrusion grooves on the same side of the two limiting columns 61 are symmetrically arranged. The two sliding sleeves 62 are respectively sleeved on the two limiting columns 61. Small protrusions are arranged on 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 wave-shaped extrusion grooves of the two limiting columns 61. The wave-shaped extrusion grooves of the limiting column 61 are used for extruding the small protrusions of the sliding sleeve 62 to make the sliding sleeve 62 reciprocating rotate. The outer sides of the two sliding sleeves 62 are respectively rotationally connected with the two sides of the spraying frame 43. The arc-shaped brush frames 63 are welded on the outer sides of the two sliding sleeves 62. There are four arc-shaped brush frames 63 in total. The two arc-shaped brush frames 63 on the same sliding sleeve 62 form a group. The two groups of arc-shaped brush frames 63 are symmetrically arranged. The two arc-shaped brush frames 63 in the same group are symmetrically arranged on the two sides of the spraying frame 43. The arc-shaped brush frames 63 are used for repeatedly brushing off the impurities accumulated on the upper portions of the two sides of the prefabricated part 2. Two limiting blocks 64 are welded on the sides of the two groups of arc-shaped brush frames 63. There are four limiting blocks 64 in total. An arc-shaped groove is formed in the limiting block 64. The four limiting blocks 64 are respectively located on the four arc-shaped brush frames 63. The two limiting blocks 64 located on the same side and not in the same group of arc-shaped brush frames 63 form a group. There are two groups of limiting blocks 64. The two limiting blocks 64 in the same group are symmetrically arranged. The sliding frame 65 is slidingly connected between the two transverse grooves 431. The transverse brush rods 66 are welded on the two sides of the sliding frame 65. The transverse brush rods 66 are used for repeatedly brushing off the impurities accumulated on the top of the prefabricated part 2. The two transverse brush rods 66 are respectively slidingly connected with the arc-shaped grooves of the two groups of limiting blocks 64. The arc-shaped grooves of the limiting blocks 64 are used for extruding and pulling the transverse brush rods 66 to reciprocating move.

[0048] While spraying the curing liquid on the prefabricated part 2, the spraying frame 43 moves to drive the sliding sleeve 62, the arc-shaped brush frame 63, the sliding frame 65 and the transverse brush rod 66 to move together. The arc-shaped brush frame 63 moves to contact the two side surfaces of the upper part of the prefabricated part 2, the transverse brush rod 66 moves to contact the top surface of the prefabricated part 2, the small protrusions in the sliding sleeve 62 reciprocate along the wavy extrusion grooves on the limiting column 61, thereby driving the four arc-shaped brush frames 63 to reciprocate in the same direction, and driving the four limiting blocks 64 to reciprocate in the same direction. The arc-shaped grooves of the two limiting blocks 64 on one side extrude the two transverse brush rods 66, and the arc-shaped grooves of the two limiting blocks 64 on the other side pull the two transverse brush rods 66, thereby driving the transverse brush rod 66 to move to one side along the horizontal groove 431 through the sliding frame 65. Then, the arc-shaped grooves of the four limiting blocks 64 extrude and pull the arc-shaped brush rod to move to the other side along the horizontal groove 431 through the sliding frame 65. Repeating the above process, the reciprocating movement of the four limiting blocks 64 in the same direction drives the transverse brush rod 66 to reciprocate transversely through extrusion and pulling. In this way, the reciprocating movement of the four arc-shaped brush frames 63 repeatedly brushes off the impurities accumulated on the two side surfaces of the upper part of the prefabricated part 2, and the transverse reciprocating movement of the transverse brush rod 66 repeatedly brushes off the impurities accumulated on the top of the prefabricated part 2. Therefore, the curing liquid sprayed later can fully contact the surface of the prefabricated part 2, thereby further enhancing the curing effect on the prefabricated part 2.
