Description

Anti-cracking film covering device and film covering method for prefabricated concrete components Technical Field

[0001] The present invention relates to the technical field of precast concrete component maintenance, in particular to an anti-cracking film covering device and a film covering method for precast concrete components. Background Art

[0002] Precast concrete components refer to prefabricated concrete components that have been completed before installation at the construction site. Common ones include precast concrete floor slabs, concrete box girders for bridges, precast concrete roof beams for industrial plants, culvert frames, precast concrete piles for foundation treatment, etc. During the process of precast concrete components, film curing is also required. Film curing is a maintenance method of covering concrete structures or components. After the initial setting of the concrete and before the final setting, the concrete curing film is manually laid to make the concrete curing film and the concrete surface closely bonded, promote the hydration effect of the concrete, and play a significant role in preventing cracking and moisturizing during the concrete curing process.

[0003] When covering some prefabricated components, it is generally done by multiple people working together to cover the concrete components. One group of people is used to fix one end of the covering layer, and the other group of people drives the covering roll to move. At this time, the covering work of the concrete prefabricated components can be achieved. This setting has the following problems:

[0004] First, the coating of prefabricated components requires the cooperation of multiple people, which wastes a lot of manpower and material resources, and a single person cannot perform the coating, so the scope of use is limited;

[0005] Secondly, when the prefabricated components are coated, the two sides of the prefabricated components cannot be in contact with the film layer, so the two sides of the prefabricated components cannot be effectively maintained, which is prone to cracking and affects the quality;

[0006] Third, the prefabricated components need to be watered to retain moisture before coating, and then the coating is performed. The coating work efficiency is low, and the watering is uneven, which results in poor maintenance. Therefore, in response to the above problems, a crack-proof coating device and coating method for concrete prefabricated components are proposed.

The extrusion cylinder provided rotates and is in close contact with the side of the prefabricated component. At this time, it is used to ensure that the plastic film is stably attached to the side of the prefabricated component, thereby ensuring the coating quality of the prefabricated component.

[0022] As an optional solution of the anti-cracking coating device and coating method for concrete precast components described in the present invention, the cutting module includes a fixed frame, a rotating column and a coating extrusion wheel, the outer side of the fixed frame is fixedly connected to the side coating module, the interior of the fixed frame is rotatably connected to a longitudinally arranged rotating column, the outer side of the rotating column is fixedly connected to the coating extrusion wheel, the top of the fixed frame is rotatably connected to a first hydraulic rod, the other end of the first hydraulic rod is rotatably connected to a rotating plate, one side of the rotating plate is rotatably connected to the fixed frame, and the other end of the rotating plate is fixedly connected to the longitudinal frame.

[0023] As an optional solution of the anti-cracking covering device and covering method for concrete precast components described in the present invention, the interior of the longitudinal frame is fixedly connected to a second motor, the end of the main shaft of the second motor is fixedly connected to a first threaded shaft, the other end of the first threaded shaft is rotatably connected to the longitudinal frame, the outer side of the first threaded shaft is spirally connected to a movable sleeve, and the bottom of the movable sleeve is fixedly connected to a cutting knife.

[0024] When coating the upper surface of the prefabricated component, the coating extrusion wheel on the outside of the rotating column can extrude the coating layer, thereby ensuring stable fitting of the prefabricated component and guaranteeing the coating quality. At the same time, after the coating work is completed, the rotating plate is driven to rotate by starting the first hydraulic rod. At this time, the longitudinal frame rotates, and the second motor inside the longitudinal frame drives the first threaded shaft to rotate, the first threaded shaft drives the movable sleeve to move, and the movable sleeve drives the cutting knife to move. At this time, automatic cutting can be performed, which is convenient for the subsequent coating of the prefabricated components of the next cycle.

[0025] As an optional solution of the anti-cracking covering device and covering method for concrete precast components described in the present invention, the synchronous moving module includes a hollow frame, a third motor and a second threaded shaft, one side of the hollow frame is fixedly connected to the covering frame, the inside of the hollow frame is fixedly connected to the third motor, the end of the main shaft of the third motor is fixedly connected to the second threaded shaft, the outer side of the second threaded shaft is spirally connected to a threaded barrel, the other end of the threaded barrel is fixedly connected to a mounting seat, the bottom of the mounting seat is fixedly connected to the extrusion module, the upper part of the threaded barrel is slidably connected to a limiting block, and the top of the limiting block is fixedly connected to the hollow frame.

[0027] When the laminating frame moves, the third motor is started to drive the second threaded shaft to rotate, and the second threaded shaft drives the threaded barrel to move. At this time, the friction plate of the extrusion module and the plastic film at the bottom can be kept in a stationary state, ensuring that one end of the plastic film can be stably fixed and the laminating work can be carried out normally.

[0029] When the laminating frame moves, sometimes the weight difference between the two sides of the laminating frame is large, and it is very difficult to pull the laminating frame at this time. By starting the fourth motor to drive the third threaded shaft to rotate, the third threaded shaft drives the counterweight block to move, so that the two sides of the laminating frame can be balanced, making it easier to pull the laminating frame to move.

[0030] As an optional solution of the crack-proof coating device and coating method for precast concrete components of the present invention, the coating steps are as follows:

[0031] Step 1: Install the film roll inside the film laminating frame, and move the film laminating frame to one side of the prefabricated component, pull a certain length of plastic film in advance, and then manually pull the film laminating frame;

[0032] Step 2: When the film covering frame is located above the prefabricated component, the extrusion module is started, and the bottom of the extrusion module squeezes the plastic film on one side;

[0033] Step 3: By manually pulling the film covering frame, the synchronous moving module is started and extended. At this time, the extrusion module is in a relatively static state with the prefabricated component. At the same time, the water pump is started. The water pump drives the water inside the water tank to be discharged through the inclined nozzle at the bottom of the hollow frame to water the prefabricated component.

[0034] Step 4: When the plastic film moves a certain distance, it contacts the prefabricated component through the water, and is used to drive the plastic film to stably lower and cover the prefabricated component. At this time, the extrusion module and the synchronous movement module can be recovered;

[0035] Step 5: When laminating the prefabricated component, the side laminating module can be activated to squeeze the two sides of the prefabricated component. At this time, the plastic film is stably and tightly attached to the side of the prefabricated component to ensure the laminating quality of the prefabricated component.

[0036] Step 6: When laminating, start the balancing module to balance the weight on both sides of the wheels, making it easier for workers to pull the laminating frame to move;

[0037] Step 7: After the prefabricated component is coated, the coating frame is moved further so that one side of the extrusion module is squeezed against the coating roll again, and then the coating roll can be cut by the cutting module;

[0038] Step 8: When it is necessary to continue laminating the prefabricated component, a certain length of laminating roll is reserved and the laminating roll is continued to be extruded by the extrusion module. At this time, the next prefabricated component can be laminarized.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] When the present invention is used, a certain length of plastic film is reserved, the extrusion module is started, and the second hydraulic rod drives the friction plate to move downward, and the bottom of the friction plate contacts the plastic film. At this time, the purpose of fixing the plastic film can be achieved, and then the film covering frame can be pulled to realize the film covering work of the prefabricated component by one person. The operation is simple. At the same time, the side film covering module provided can ensure that the side of the prefabricated component is squeezed, ensuring that the side of the prefabricated component is tightly covered, thereby ensuring the quality of the prefabricated component. At the same time, the nozzle provided can evenly and stably water the surface of the prefabricated component for maintenance under the action of the water pump, thereby ensuring the quality of the prefabricated component.

[0041] The fifth motor drives the film covering roll to rotate, which ensures that the plastic film can be easily pulled and conveniently covered on the surface of the prefabricated component.

[0042] When the laminating frame moves, the third motor is started to drive the second threaded shaft to rotate, and the second threaded shaft drives the threaded barrel to move. At this time, the extrusion module and the plastic film at the bottom can be kept in a stationary state, ensuring that one end of the plastic film can be stably fixed and the laminating work can be carried out normally.

[0043] When coating the side of the prefabricated component, the first motor is started to drive the driving gear to rotate, and the driven gear drives the rotating shaft to rotate. At this time, the extrusion wheel can squeeze and fix the corner of the prefabricated component, and at the same time, the extrusion cylinder is rotated to closely contact the side of the prefabricated component, which is used to ensure that the plastic film is stably attached to the side of the prefabricated component and the coating quality of the prefabricated component is guaranteed.

[0044] The spring drives the rotating ring to move, and the rotating ring drives the rotating shaft to move, which can ensure that the extrusion cylinder is in stable contact with the side of the prefabricated component;

[0045] When the laminating frame moves, its laminating extrusion wheel rotates. At this time, the laminating extrusion wheel stably squeezes the plastic film, so that the plastic film is stably in close contact with the upper surface of the prefabricated component, ensuring the quality of the laminating. After the peritoneum of the prefabricated component is completed, the first hydraulic rod is started to drive the rotating plate to rotate, and at the same time the second motor drives the first threaded shaft to rotate. At this time, the first threaded shaft drives the moving sleeve to move, and the moving sleeve can drive the cutting knife to move, which is used to cut the plastic film, facilitating the subsequent laminating work.

[0046] When the laminating frame moves, sometimes the weight difference between the two sides of the laminating frame is large, and it is very difficult to pull the laminating frame at this time. By starting the fourth motor to drive the third threaded shaft to rotate, the third threaded shaft drives the counterweight block to move, so that the two sides of the laminating frame can be balanced, making it easier to pull the laminating frame to move.

[0082] When coating the upper surface of the prefabricated component, the coating extrusion wheel 403 on the outside of the rotating column 402 can squeeze the coating layer, thereby ensuring stable fitting to the prefabricated component and guaranteeing the coating quality. After the coating work is completed, the rotating plate 405 is driven to rotate by starting the first hydraulic rod 404. At this time, the longitudinal frame 406 rotates, and the second motor 407 inside the longitudinal frame 406 drives the first threaded shaft 408 to rotate, the first threaded shaft 408 drives the movable sleeve 409 to move, and the movable sleeve 409 drives the cutting knife 410 to move. At this time, automatic cutting can be performed, which is convenient for the subsequent coating of the prefabricated components of the next cycle.

Specifically, the above-mentioned synchronous moving module 5 includes a hollow frame 501, a third motor 502 and a second threaded shaft 503. One side of the above-mentioned hollow frame 501 is fixedly connected to the coating frame 1, the interior of the above-mentioned hollow frame 501 is fixedly connected to the third motor 502, the main shaft end of the above-mentioned third motor 502 is fixedly connected to the second threaded shaft 503, the outer side of the above-mentioned second threaded shaft 503 is spirally connected to a threaded barrel 504, the other end of the above-mentioned threaded barrel 504 is fixedly connected to a mounting seat 505, the bottom of the above-mentioned mounting seat 505 is fixedly connected to the extrusion module 6, the upper part of the above-mentioned threaded barrel 504 is slidably connected to a limiting block 506, and the top of the above-mentioned limiting block 506 is fixedly connected to the hollow frame 501.

[0085] The extrusion module 6 includes a second hydraulic rod 601 and a friction plate 602. The top of the second hydraulic rod 601 is fixedly connected to the synchronous movement module 5. The bottom of the second hydraulic rod 601 is fixedly connected to the friction plate 602. The friction plate 602 is made of rubber block material.

[0086] When the laminating frame 1 moves, the third motor 502 is started to drive the second threaded shaft 503 to rotate, and the second threaded shaft 503 drives the threaded barrel 504 to move. At this time, the friction plate 602 of the extrusion module 6 and the plastic film at the bottom can be kept in a stationary state, ensuring that one end of the plastic film can be stably fixed and the laminating work can be carried out normally. The set limit block 506 can ensure the stable movement of the threaded barrel 504.

[0087] Example 5

[0088] This embodiment is an improvement on Example 4, please refer to Figure 7. Specifically, the above-mentioned balancing module 7 includes a counterweight frame 701, a fourth motor 702 and a third threaded shaft 703.

[0089] When the laminating frame 1 moves, sometimes the weight difference between the two sides of the laminating frame 1 is large. At this time, it is very difficult to pull the laminating frame 1. By starting the fourth motor 702 to drive the third threaded shaft 703 to rotate, the third threaded shaft 703 drives the counterweight block 704 to move. At this time, the two sides of the laminating frame 1 can be balanced, which facilitates pulling the laminating frame 1 to move.
