Description

Technical Field

[0001] The invention relates to the technical field related to precast concrete panels, and in particular to a forming and processing device for precast concrete panels in construction engineering. Background Art

[0002] Hollow cement precast panels are a type of prefabricated floor slab with one or more longitudinal holes inside to save materials and reduce weight. The size of the panels is determined by the size of the house bay and the capacity of the lifting machinery. The holes in the hollow cement precast panels are conducive to sound insulation and heat insulation. Generally, in order to enhance its strength, steel bars are usually set inside, and then concrete is poured into the molding mold and then allowed to solidify to complete the molding of the hollow cement precast panels.

[0003] In the process of precast panel forming, concrete is usually poured into the mold for flattening. Traditionally, workers use flattening tools to flatten the concrete in a certain area, and then disassemble the mold to demould after flattening. However, this method often encounters a series of problems in the actual process:

[0004] 1. The area of ​​artificial flattening is small, and the flat surfaces between the flattened areas are not on the same plane. The overall pressing force is small, which easily leads to a low pressing density and difficulty in shaping. In addition, the efficiency of artificial flattening is low, which is not conducive to the forming of large quantities of prefabricated panels.

[0005] 2. The excess concrete after pressing is usually pushed out of the mold, resulting in a waste of concrete materials. Even if the concrete that falls to the ground is recycled, the dust mixed in the concrete can easily affect its viscosity, thus affecting the quality of the precast panels after shaping. Summary of the invention

[0006] 1. Technical solution

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a kind of concrete precast panel forming and processing equipment for construction engineering, including a tractor, a connecting plate, an inner core mold, a casting frame, a side storage device, a rolling device, and a tail storage device. The rear end of the tractor is equipped with a connecting plate, and the inner core molds are evenly installed on the connecting plate. The connecting plate and the casting frame are connected by a locking piece, and the left and right sides of the casting frame are equipped with side storage devices, the front end of the casting frame is equipped with a rolling device, and the rear end of the casting frame is equipped with a tail storage device.

[0008] The casting frame comprises a front baffle, a fixed plate, a cylinder 1, a side baffle, a turning frame, a rotating shaft, a motor 1, a cylinder 2, and a rear baffle. The front baffle is connected to the connecting plate by a locking piece. The left and right ends of the front baffle are symmetrically provided with fixed plates. A cylinder 1 is connected between the fixed plate and the side baffle. The rear end of the fixed plate is connected to the rotating shaft through a bearing. The turning frame is installed on the rotating shaft. One end of the rotating shaft is connected to the output shaft of the motor 1. The motor 1 is installed on the fixed plate through a base. The turning frame is connected to the rear baffle through the cylinder 2. The front baffle, the side baffle and the rear baffle are arranged in a return shape to form a material trough. Concrete is poured into the material trough, and the concrete is rolled and shaped by a rolling device. After shaping, the concrete is rolled and shaped by a rolling device. Cylinder 2 drives the rear baffle to move backward to separate it from the rear end of the inner core mold (the rear baffle moves backward to ensure that the rear end of the concrete will not be damaged when the rear baffle is flipped), and then the flip frame and the rear baffle that moves backward are flipped upward by motor 1, and then the connecting plate and the inner core mold are driven forward by the tractor. When the rear end of the inner core mold that moves forward is engaged with the front baffle, the two move forward together, thereby driving the casting frame to be demoulded from the molded concrete, and the casting frame is driven by the tractor to move to the next prefabrication position, and stops moving after moving to the designated position, and the flip frame and the rear baffle are reset in turn, and the connecting plate and the inner core mold are driven backward by the tractor until the rear end of the inner core mold is re-mounted on the rear baffle.

[0009] The side storage device comprises a retention frame, a push plate, a return spring, a housing, a rack plate 1, a gear, a rack plate 2 and an extrusion block. The retention frame is installed at the upper end of the side end baffle. The retention frame and the push plate are connected by a sliding fit. When the concrete is poured, the push plate is in the innermost position. At this time, there is no extra space on the retention frame, which ensures that the concrete is poured into the trough. During the later rolling, the push plate moves a short distance outward. At this time, a part of the space is left between the inner part of the push plate and the retention frame, so that It ensures that excess concrete after rolling can be squeezed and flowed into the storage space for temporary retention, and a reset spring is connected between the retention frame and the push plate, which plays a reset role. The front end of the push plate is connected to the rack plate 1, the rack plate 1 is located in the shell, the shell is installed on the outer wall of the retention frame, the rack plate 1 is meshed with the rear end of the gear, the gear is connected to the shell through a pin shaft, the front end of the gear is meshed with the rack plate 2, the rack plate 2 and the shell are connected in a left-right sliding fit, and an extrusion block is installed at the inner end of the rack plate 2.

[0010] The rolling device comprises a fixed frame, an electric slider, a moving frame, a movable plate, a pressure plate, an extrusion rod, a cam, a second motor, a working spring and a rolling wheel. The fixed frame is installed on the fixed plate, and an electric slider is installed on the side wall of the fixed frame. The setting of the electric slider plays a role in driving the moving frame to move forward and backward. The electric slider is provided with a moving frame, and the moving frame and the movable plate are connected in a sliding manner. The movable plate is installed at the upper end of the pressure plate, and a working spring is connected between the pressure plate and the moving frame. The working spring plays a resetting role. An extrusion rod is installed on the pressure plate, and the upper end surface of the extrusion rod fits the cam. The cam is installed on the output shaft of the second motor, and the second motor is installed on the moving frame through a motor seat. The cam is driven to rotate by the second motor. According to the cam principle and the elastic resetting connection of the working spring, the extrusion rod and the pressure plate vibrate up and down, and the rolling wheel is connected to the moving frame through a pin shaft, and the rolling wheel and the pressure plate are arranged front to back.

[0011] The end storage device includes a connecting frame, a connecting spring, a folding plate, and a storage frame. The connecting frame is installed at the rear end of the fixed plate. A connecting spring is connected between the connecting frame and the middle of the storage frame. The connecting spring plays a resetting role. The storage frame is connected to the fixed plate by sliding fit. A folding plate is connected between the connecting frame and the upper end of the storage frame. The folding plate plays a dust-proof and beautiful effect.

[0012] Preferably, the front baffle plate includes a plate body, an entry hole, a locking plate, a positioning plate, a built-in spring, and an inner groove. The entry holes are evenly opened in the middle of the plate body, and the inner grooves are symmetrically opened at the upper and lower ends of the entry hole. The inner groove and the locking plate are connected by a pin shaft, and a built-in spring is connected between the inner groove and the locking plate. The built-in spring plays a resetting role, and a positioning plate is installed on the inner side wall of the inner groove. The setting of the positioning plate ensures that the locking plate is in a vertical state after rotating into the locking groove under the action of elasticity. At this time, as the inner core mold moves forward, the locking plate and the inner core mold are in a card-locked state, and the two move forward together, but when the inner core mold moves backward, the locking plate loses the locking effect, and the inner core mold moves backward alone.

[0013] Preferably, locking grooves are provided on the upper and lower sides of the rear end of the inner core mold, and the positions of the locking grooves and the locking plates correspond to each other. The built-in spring in the initial state is in a compressed state, ensuring that when the locking grooves provided in the inner core mold enter the entry hole, the locking plate can be rotated into the locking grooves.

[0014] Preferably, the upper and lower ends of the front baffle are evenly provided with a plug hole 1, the upper and lower ends of the side baffle are evenly provided with a plug hole 2, and the upper and lower ends of the rear baffle are evenly provided with a plug hole 3. The provision of the plug hole 1, the plug hole 2, and the plug hole 3 is convenient for inserting the steel bar. When the steel bar needs to be inserted, the inner core mold is not in the casting frame at this time, and the side end baffles move to both sides by the cylinder 1, and the rear baffle moves to the rear side under the drive of the cylinder 2. The purpose of this is to ensure the smooth insertion of the steel bar. After the steel bar is inserted and bound, the side end baffles move toward each other, and the rear baffle is reset, so as to position the bound steel mesh. After the concrete is formed in the later stage, the side end baffles arranged on both sides still need to move in the opposite direction and the rear baffle moves backward, so as to separate from the steel mesh, thereby ensuring the separation of the present invention from the prefabricated board that has been initially finalized. The middle part of the rear baffle is evenly provided with embedded holes, and the rear end of the inner core mold in the initial position is located in the embedded holes, which has the effect of sleeve support for the rear end of the inner core mold.

[0015] Preferably, the inclined surface of the extrusion block is a structure that gradually inclines forward from the outside to the inside, which reduces the difficulty of extrusion, and the initial state of the return spring is a stretched state.

[0016] Preferably, the outer surface of the rolling wheel is paved with a smooth layer, and a scraper block is provided at the rear end of the flat plate, and the scraper block is against the smooth layer. The design of the smooth layer and the scraper block is to avoid the concrete from sticking to the rolling wheel for a long time. The smoothness of the smooth layer increases the possibility of concrete falling off, and the scraper block directly scrapes off the concrete on the smooth layer.

[0017] Preferably, the bottom end surface of the storage frame is a structure that gradually slopes downward from the back to the front, which reduces the difficulty of shoveling excess concrete into the storage frame and also reduces the difficulty of the concrete in the storage frame falling back into the trough at a later time.

[0018] Preferably, the locking piece passes through the connecting plate and is connected to the front baffle plate by means of threaded cooperation. When the present invention is not in use, the connecting plate and the front baffle plate are locked, ensuring that the inner core mold can be inside the casting frame when the tractor is pulling, thereby reducing the length of the present invention when moving. When the present invention is in use, the locking piece needs to be taken out to ensure the normal operation of the present invention.

[0019] (II) Beneficial effects

[0020] 1. The concrete precast panel forming and processing equipment for construction engineering described in the present invention adopts automatic flattening and demoulding to form the precast panel. The staff only needs to pour the concrete, which greatly saves manpower. The excess concrete material is temporarily retained. After demoulding, the retained concrete material is re-input into the casting frame, thereby improving the utilization rate of the concrete. The temporarily retained concrete will not be mixed with dust, thereby maintaining the viscosity of the concrete and avoiding the situation where the quality of the precast panel is reduced.

[0021] 2. The present invention discloses a kind of construction engineering concrete precast panel forming and processing equipment. The present invention adopts the design concept of integrated automatic rolling and demoulding. After the concrete is poured, large-area rolling is performed to improve the surface flatness. The automatic rolling improves the density of the concrete. The excess concrete flows into the storage space and the storage frame. After rolling and shaping, the rear baffle is turned back and flipped, and the side end baffle moves outward to perform demoulding. The inner core mold and the casting frame are withdrawn in order, thereby reducing the possibility of concrete damage after demoulding and shaping. The automatic molding process reduces the labor cost and improves the molding efficiency. It is suitable for the molding of large quantities of precast panels.

[0022] 3. The side storage device of the present invention adopts the design concept of structural linkage, and is in two forms during the pouring of concrete and the later forming process. When the concrete is poured, the push plate is in the innermost position, and there is no storage space in the retention frame at this time, which ensures that the concrete is completely poured into the casting frame. During the later rolling forming, the push plate moves outward, and a storage space is formed between the inner part of the push plate and the retention frame, thereby giving a certain retention space for the residual material, and there is no need to push the residual material onto the ground. When the present invention moves to the next prefabrication point, this part of the retained residual material will be pushed back into the casting frame, thereby improving the utilization rate of the concrete;

[0023] 4. In the concrete precast panel forming and processing equipment for construction projects described in the present invention, the tail receiving device temporarily collects the remaining materials that have not flowed into the storage space, and when the present invention moves to the next precast point, it will also be pushed back into the casting frame.

[0034] The embodiments of the present invention are described below with reference to the accompanying drawings. In the process, in order to ensure the clarity and convenience of the description, we may exaggerate the width of the lines or the size of the components in the drawings.

[0035] In addition, the terms used below are defined based on the functions of the present invention and may differ depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire contents of this specification.

[0036] like Figures 1 to 9 As shown, a concrete precast panel forming and processing equipment for construction projects includes a tractor 1, a connecting plate 2, an inner core mold 3, a casting frame 4, a side receiving device 5, a rolling device 6, and a tail receiving device 7. The rear end of the tractor 1 is equipped with a connecting plate 2, and the inner core mold 3 is evenly installed on the connecting plate 2. The connecting plate 2 and the casting frame 4 are connected by a locking piece. The left and right sides of the casting frame 4 are equipped with side receiving devices 5, the front end of the casting frame 4 is equipped with a rolling device 6, and the rear end of the casting frame 4 is equipped with a tail receiving device 7.

[0037] The pouring frame 4 includes a front baffle plate 41, a fixed plate 42, a cylinder 1 43, a side baffle plate 44, a flip frame 45, a rotating shaft 46, a motor 1 47, a cylinder 2 48, and a rear baffle plate 49. The front baffle plate 41 is connected to the connecting plate 2 by a locking piece. The left and right ends of the front baffle plate 41 are symmetrically installed with fixed plates 42. A cylinder 1 43 is connected between the fixed plate 42 and the side baffle plate 44. The rear end of the fixed plate 42 is connected to the rotating shaft 46 through a bearing. A flip frame 45 is installed on the rotating shaft 46. One end of the rotating shaft 46 is connected to the output shaft of the motor 1 47. The motor 1 47 is installed on the fixed plate 42 through a base. The flip frame 45 is connected to the rear baffle plate 49 by a cylinder 2 48. The front baffle plate 41, the side baffle plate 44 and the rear baffle plate 49 are arranged in a return shape, thereby forming a material trough. Concrete is poured into the material trough and the concrete is rolled by the rolling device 6. The concrete is rolled and shaped. After shaping, the rear side baffle 49 is driven by cylinder 2 48 to move backward to separate it from the rear end of the inner core mold 3 (the rearward movement of the rear side baffle 49 is to ensure that the rear end part of the shaped concrete will not be damaged when the rear side baffle 49 is turned over). Then, the overturning frame 45 and the rearward-moved rear side baffle 49 are driven to turn upward by motor 1 47, and then the connecting plate 2 and the inner core mold 3 are driven forward by the tractor 1. After the rear end of the moved inner core mold 3 is engaged with the front side baffle 41, the two move forward together, thereby driving the casting frame 4 to be demoulded from the shaped concrete, and the casting frame 4 is driven by the tractor 1 to move to the next prefabricated position, and stops moving after moving to the designated position. The overturning frame 45 and the rear side baffle 49 are reset in turn, and the connecting plate 2 and the inner core mold 3 are driven backward by the tractor 1 until the rear end of the inner core mold 3 is re-mounted on the rear side baffle 49.

[0038] The front baffle plate 41 comprises a plate body 411, an entry hole 412, a locking plate 413, a positioning plate 414, an internal spring 415 and an internal groove 416. The entry hole 412 is evenly provided in the middle of the plate body 411, and internal grooves 416 are symmetrically provided at the upper and lower ends of the entry hole 412. The internal groove 416 is connected to the locking plate 413 by a pin shaft, and an internal spring 415 is connected between the internal groove 416 and the locking plate 413. The internal spring 415 plays a role of resetting, and a positioning plate 414 is installed on the inner side wall of the internal groove. The setting of the positioning plate 414 ensures that the locking plate 413 is in a vertical state after rotating into the locking groove under the action of elasticity. At this time, as the inner core mold 3 moves forward, the locking plate 413 and the inner core mold 3 are in a card-connected and locked state, and the two move forward together, but when the inner core mold 3 moves backward, the locking plate 413 loses its lock. The locking effect is lost, and the inner core mold 3 moves backward alone. During specific work, after the concrete is pressed and shaped, the tractor 1 drives the connecting plate 2 and the inner core mold 3 to move forward alone, thereby demolding. When the locking groove opened at the rear end of the inner core mold 3 moves to the entry hole 412, the locking plate 413 is inserted into the locking groove under the elasticity of the built-in spring 415 and the limit of the positioning plate 414, thereby forming a snap-fit ​​relationship with the inner core mold 3. At this time, the position between the rear end of the inner core mold 3 and the plate body 411 is temporarily locked, and the two move forward together. When the present invention moves as a whole to the next prefabricated position, the tractor 1 drives the connecting plate 2 and the inner core mold 3 to move backward. At this time, the inner core mold 3 and the plate body 411 cannot form a snap-fit ​​relationship. As the inner core mold 3 moves backward, the locking plate 413 will be squeezed into the inner groove 416.

[0039] The upper and lower sides of the rear end of the inner core mold 3 are provided with locking grooves, and the positions of the locking grooves and the locking plates 413 correspond. The built-in spring 415 in the initial state is in a compressed state, which ensures that when the locking grooves provided by the inner core mold 3 enter the entry hole 412, the locking plates 413 can be rotated into the locking grooves. The upper and lower ends of the front side baffle plate 41 are evenly provided with insertion holes 1, the upper and lower ends of the side end baffle plate 44 are evenly provided with insertion holes 2, and the upper and lower ends of the rear side baffle plate 49 are evenly provided with insertion holes 3. The provision of insertion holes 1, 2, and 3 is convenient for the insertion of steel bars. When steel bars need to be inserted, the inner core mold 3 is not in the casting frame 4 at this time, and the side end baffle plates 44 move to both sides by the cylinder 1 43, and the rear side baffle plate 49 moves to the rear side under the drive of the cylinder 2 48. The purpose of this is to ensure the smooth insertion of the steel bars. After the steel bars are inserted and bound, the side baffle plates 49 are The end baffles 44 move towards each other, and the rear baffle 49 is reset, thereby positioning the bound steel mesh. After the concrete is formed in the later stage, the side end baffles 44 arranged on both sides still need to move in the opposite direction and the rear baffle 49 moves backward, thereby separating from the steel mesh, ensuring the separation of the present invention from the prefabricated panel that has been initially finalized. The middle part of the rear baffle 49 is evenly provided with embedded holes, and the rear end of the inner core mold 3 in the initial position is located in the embedded holes, which has the effect of sleeve support for the rear end of the inner core mold 3. The locking piece passes through the connecting plate 2 and is connected to the front baffle 41 by threaded cooperation. When the present invention is not in use, the connecting plate 2 and the front baffle 41 are locked, ensuring that the inner core mold 3 can be inside the casting frame 4 when the tractor 1 is pulling, reducing the length of the present invention when moving. When the present invention is in use, the locking piece needs to be taken out to ensure the normal operation of the present invention.

[0040] The side storage device 5 includes a retention frame 51, a push plate 52, a return spring 53, a housing 54, a rack plate 1 55, a gear 56, a rack plate 2 57 and an extrusion block 58. The retention frame 51 is installed on the upper end of the side end baffle 44. The retention frame 51 and the push plate 52 are connected by sliding fit. When the concrete is poured, the push plate 52 is in the innermost position. At this time, there is no extra space on the retention frame 51, which ensures that the concrete is poured into the trough. During the later rolling, the push plate 52 moves a short distance to the outside. At this time A portion of space is left between the inner part of the push plate 52 and the retention frame 51, thereby ensuring that excess concrete after rolling can be squeezed and flowed into the storage space for temporary retention, and a return spring 53 is connected between the retention frame 51 and the push plate 52, and the return spring 53 plays a role of reset. The front end of the push plate 52 is connected to the rack plate 1 55, and the rack plate 1 55 is located in the shell 54, and the shell 54 is installed on the outer wall of the retention frame 51. The rack plate 1 55 is meshed with the rear end of the gear 56, and the gear 56 is connected to the shell 54 through a pin shaft. Then, the front end of the gear 56 is meshed with the rack plate 2 57, and the rack plate 2 57 is connected to the housing 54 by sliding fit. The inner end of the rack plate 2 57 is installed with a squeezing block 58, and the inclined surface of the squeezing block 58 is a structure that gradually tilts forward from the outside to the inside, which reduces the difficulty of squeezing, and the initial state of the reset spring 53 is a stretched state. When working, the moving frame 63 in the initial position is located at the front side. At this time, the squeezing block 58 is squeezed to hide in the housing 54, and the rack plate 1 55, the gear 56, and the rack plate 2 5 7, the push plate 52 is at the innermost side so that the inner surface between the push plate 52 and the side baffle plate 44 at the corresponding position is in the same plane (the reset spring 53 is in a stretched state at this time). When the moving frame 63 moves backward, when the moving frame 63 no longer squeezes the extrusion block 58, the push plate 52 moves outward under the reset of the reset spring 53. At this time, a storage space is formed between the inner position of the push plate 52 and the retention frame 51, which facilitates the flow of residual material to both sides when the rolling device 6 is rolling, thereby achieving the purpose of temporary storage.

[0041] The rolling device 6 includes a fixed frame 61, an electric slider 62, a moving frame 63, a movable plate 64, a pressing plate 65, an extrusion rod 66, a cam 67, a second motor 68, a working spring 69 and a rolling wheel 70. The fixed frame 61 is installed on the fixed plate 42, and an electric slider 62 is installed on the side wall of the fixed frame 61. The setting of the electric slider 62 plays a role in driving the moving frame 63 to move forward and backward. The electric slider 62 is provided with a moving frame 63, and the moving frame 63 and the movable plate 64 are connected in a sliding fit. The movable plate 64 is installed at the upper end of the pressing plate 65, and a working spring 69 is connected between the pressing plate 65 and the moving frame 63. The working spring 69 plays a role of resetting. An extrusion rod 66 is installed on the pressing plate 65, and the upper end surface of the extrusion rod 66 is in contact with the cam 67. The cam 67 is installed on the output shaft of the second motor 68, and the second motor 68 is installed on the moving frame 63 through the motor seat. Machine 2 68 drives cam 67 to rotate. According to the cam principle and the elastic reset connection of working spring 69, extrusion rod 66 and pressing plate 65 vibrate up and down. A rolling wheel 70 is connected to the movable frame 63 through a pin shaft, and the rolling wheel 70 and the pressing plate 65 are arranged front to back. The outer surface of the rolling wheel 70 is paved with a smooth layer. A scraping block is provided at the rear end of the pressing plate 65, and the scraping block is against the smooth layer. The design of the smooth layer and the scraping block is to avoid the situation where concrete sticks to the rolling wheel 70 for a long time. The smoothness of the smooth layer increases the possibility of concrete falling off. The scraping block directly scrapes the concrete on the smooth layer. During specific work, after the concrete is poured, the movable frame 63 is driven to move backward by the electric slider 62. At this time, the concrete is subjected to high-frequency vibration flattening by the pressing plate 65 that vibrates up and down, and then the rolling of the rolling wheel 70 is combined to roll and shape the concrete.

[0042] The end storage device 7 includes a connecting frame 71, a connecting spring 72, a folding plate 73, and a storage frame 74. The connecting frame 71 is installed at the rear end of the fixed plate 42. A connecting spring 72 is connected between the connecting frame 71 and the middle of the storage frame 74. The connecting spring 72 plays a role in resetting. The storage frame 74 is connected to the fixed plate 42 by sliding cooperation. A folding plate 73 is connected between the connecting frame 71 and the upper end of the storage frame 74. The folding plate 73 plays a role in dustproof and beautiful appearance. The bottom end of the storage frame 74 The surface is a structure that gradually slopes downward from the back to the front, which reduces the difficulty of shoveling excess concrete into the storage frame 74, and also reduces the difficulty of the concrete in the storage frame 74 falling back into the material trough at a later time. During specific operation, when the moving frame 63 moves backward and contacts the storage frame 74, at this time, a part of the remaining material that has not flowed out to the sides will be shoveled into the storage frame 74. After the moving frame 63 contacts the storage frame 74, the two move backward together until the position of the rolling wheel 70 is located on the rear side of the precast panel after the molding.

[0048] a. The moving frame 63 is driven to move backward by the electric slider 62. During the backward movement, the moving frame 63 is separated from the extrusion block 58. Under the reset of the reset spring 53, the push plate 52 moves outward. At this time, a storage space is formed between the inner part of the push plate 52 and the retention frame 51;

[0049] b. The moving frame 63 continues to move, and the concrete is flattened by high-frequency vibration through the pressing plate 65 that vibrates up and down, and then the concrete is rolled and shaped by the rolling wheel 70, and some excess concrete flows into the storage space;

[0050] c. When the moving frame 63 moving backward contacts the storage frame 74, a part of the residual material that has not flowed out to the sides will be shoveled into the storage frame 74. After the moving frame 63 contacts the storage frame 74, the two move backward together until the position of the rolling wheel 70 is located at the rear side of the finalized prefabricated board, and the moving frame 63 stops moving;

[0051] S5. After shaping, the rear baffle plate 49 is driven by the cylinder 2 48 to move backward to separate it from the rear end of the inner core mold 3, and the rear baffle plate 49 is separated from the rear side of the precast plate, and sufficient turning space is provided.
