Description

Technical Field

[0001] This invention belongs to the technical field of integrated film coating machines, specifically relating to a rechargeable vibratory film coating machine for pouring concrete. Background Technology

[0002] When pouring concrete for bridge supports, beams, and building frames, it is essential to remove air trapped within the concrete and meet construction quality standards. This is typically achieved by using a concrete vibrator to vibrate the concrete, making it more compact and free of air bubbles.

[0003] Currently, the concrete vibrator with film-coating function, with announcement number CN219952731U, includes a vibrating plate with flat top and bottom surfaces. A vibrating motor is fixedly connected to the top of the vibrating plate, which is used to drag across the concrete surface. A main rod is fixedly connected to one side of the vibrating plate, and a handle is fixedly connected to the end of the main rod. A support rod is fixedly connected between the main rod and the vibrating plate. A secondary rod is fixedly connected to one side of the main rod, and a frame is fixedly connected to the end of the secondary rod. A roller is fixedly connected to the inner side of the frame, and a film roller is movably connected to the outer surface of the roller. A shaft plate is detachably connected to the end of the frame, and the end of the roller is inserted into the shaft plate. This solution can achieve simultaneous vibration and film coating of the concrete, without requiring multiple people to perform the work, thus saving manpower and increasing efficiency.

[0004] However, some problems exist: 1. Due to the vibration mechanism, the support rollers of this device also vibrate, causing vibration and tilting during film application. 2. In cold winters, the support rollers are prone to freezing and adhesion, preventing the film from adhering to the concrete, which also requires insulation. 3. When not in use, the support rollers are positioned low, making them susceptible to damage during handling, resulting in poor film application. Summary of the Invention

[0005] This invention provides a rechargeable vibratory film coating machine for pouring concrete, which reduces the impact of vibration generated by the vibration mechanism on the support roller.

[0006] This solution provides a rechargeable vibratory film coating integrated machine for pouring concrete, including a support rod, a scraper and a support roller. The support rod is equipped with a handle and an electrical box. It also includes a frame, which is rotatably connected to the scraper and the support roller. The upper end of the scraper is equipped with a vibration mechanism.

[0007] It also includes a vibration damping mechanism, one end of which is fixedly connected to the scraper and the other end of which is fixedly connected to the frame.

[0008] The principle of this solution is as follows: When in use, the vibration mechanism is activated, causing the scraper to start vibrating. Then, the support roller and the scraper come into contact with the concrete. The operator pulls the handle backward, causing the scraper to vibrate and making the concrete smooth. At the same time, the vibration damping mechanism can reduce the vibration on the support roller, so that the film is stably covered on the concrete as the support roller rolls, thus completing the vibration covering.

[0009] The beneficial effect of this solution is that the device reduces the vibration on the support roller by adding a vibration damping mechanism, thereby improving the stability of the support roller coating.

[0010] Furthermore, the vibration damping mechanism includes a lower fixed frame, an upper fixed frame, a cylinder, a buffer component, a compression rod, a buffer piston, and a floating piston. One end of the upper fixed frame is fixedly connected to a scraper, and the other end is slidably connected to the compression rod. The other end of the compression rod is fixedly connected to the buffer piston. The cylinder includes a first cavity and a second cavity, the first cavity being smaller than the second cavity and communicating with the second cavity. The buffer piston is slidably connected to the first cavity, and the floating piston is slidably connected to the second cavity. One end of the lower fixed frame is fixedly connected to a frame, and the other end is fixedly connected to the cylinder. The first cavity and the second cavity are provided with an air inlet and an air outlet, and the air inlet and the air outlet are provided with one-way valves.

[0011] During the lamination process, the vibration of the scraper transmits the vibrational force to the upper fixed frame. The up-and-down vibration of the upper fixed frame causes the extrusion rod to move up and down. The buffer piston of the extrusion rod moves up and down within the condensate-filled oil. Simultaneously, the change in space within the first chamber also causes the floating piston in the second chamber to move up and down, compressing the air within the second chamber. This forces the gas to enter through the air inlet and exit through the air outlet, converting mechanical energy into heat energy. This reduces the mechanical energy transmitted to the lower fixed frame, significantly reducing frame vibration and minimizing the impact of the vibration mechanism on the support rollers.

[0012] This device utilizes the changes in air and hydraulic pressure within the first and second chambers to convert mechanical energy within the cylinder into heat energy, reducing vibration of the support roller and making the support roller more stable during film coating, thus reducing the likelihood of deviation.

[0013] Furthermore, the support shaft of the support roller is provided with a through hole, and the air outlet is connected to the through hole of the support shaft through a rotary joint. When the vibration mechanism vibrates, the damping mechanism generates a large amount of heat energy, causing hot air to exit through the air outlet. Since the air outlet is connected to the support shaft, the hot air enters the interior of the support roller, providing a simple heating effect. This prevents the film on the support roller from freezing and adhering, and the film coating effect is better after heat preservation.

[0014] Furthermore, it also includes an air storage tank and a lifting cylinder. The air outlet and the through hole are connected through the air storage tank. A pressure valve is provided at the connection between the air storage tank and the through hole. The lifting cylinder includes a lifting cylinder body, a reset component, and a piston rod. The lifting cylinder body is connected to the air storage tank. One end of the piston rod is slidably connected to the lifting cylinder body, and the other end is fixedly connected to the support shaft. The lifting cylinder body is fixedly connected to the frame. One end of the reset component is fixedly connected to the piston rod, and the other end is fixedly connected to the lifting cylinder body.

[0015] When not in use, the piston rod of the support roller is not extended under the action of the reset component, and the support roller is also in a higher position. This prevents damage to the film on the support roller when the operator moves or drags it. When needed, the operator starts the vibration mechanism, which vibrates. The hot air generated by the vibration damping mechanism enters the air storage tank from the air outlet, and then enters the lifting cylinder, causing the piston rod to extend and the support roller to extend and contact the concrete. As more and more hot air enters the air storage tank, the pressure in the air storage tank increases. When the set value is reached, the pressure valve opens, allowing the hot air in the air storage tank to flow into the support roller, heating and insulating the film on the support roller.

[0016] Furthermore, a limiting mechanism is provided at the right end of the frame. The limiting mechanism includes a support shaft, a pressure plate, a slide rod, a baffle, a spring, and a pin. Support shafts are welded to both the left and right ends of the scraper. The support shafts are rotatably connected to the frame. The right end of the frame contacts the pressure plate. A slide rod is welded to the right end of the frame. The slide rod is slidably connected to the pressure plate. A baffle is welded to the right end of the slide rod. The baffle is slidably connected to the pressure plate. A spring is provided on the outer side of the slide rod.

[0017] By rotating the scraper and using the spring to act on the pressure plate, the pin is inserted into the support shaft, which limits the support shaft. This allows the scraper to be adjusted in angle during use, enabling the device to be tilted to a certain degree for operation. This makes the device more adaptable and easier to use.

[0018] Furthermore, one end of the spring is fixedly connected to the pressure plate, and the other end of the spring is welded to the baffle. By incorporating the spring, the pressure plate can automatically reset.

[0019] Furthermore, a pin is welded to the lower left side of the pressure plate, and the pin is slidably connected to the support shaft. By setting the pin, the support shaft can be limited.

[0020] Furthermore, the vibration mechanism includes a housing, a motor, a lever, a connecting shaft, a stop bar, and a torsion spring. The housing is welded to the upper end of the scraper, and the motor is fixedly mounted on the upper end of the housing. The motor's shaft passes through the housing and is rotatably connected to it. The connecting shaft is welded to the inner wall of the housing, and a stop bar is mounted on the outer side of the connecting shaft via a bearing. A torsion spring is also provided on the outer side of the connecting shaft. The motor drives the lever to rotate, causing it to strike the stop bar, which in turn rotates and collides with the scraper. This causes the scraper to vibrate during its movement, thereby compacting the concrete and ensuring a tighter bond between the membrane on the support roller and the concrete.

[0021] Furthermore, a lever is welded to the surface of the rotating shaft, and the lever contacts the stop lever. By setting the lever, the stop lever can be rotated.

[0022] Furthermore, one end of the torsion spring is welded to the frame, and the other end of the torsion spring is welded to the stop bar. By incorporating the torsion spring, the stop bar can be easily reset. Attached Figure Description

[0029] like Figure 1 , Figure 4 , Figure 5 As shown:

[0030] This solution provides a rechargeable vibratory film coating integrated machine for pouring concrete, including a support rod 2, a scraper 5 and a support roller 6. A handle 3 is provided inside the support rod 2, and an electrical box 4 is provided on the support rod 2. It also includes a frame 1, which is rotatably connected to the scraper 5 and the support roller 6. A vibration mechanism 8 is provided at the upper end of the scraper 5.

[0031] It also includes a vibration damping mechanism 9, which includes a lower fixed frame 90, an upper fixed frame 91, a cylinder, a buffer 92, a pressing rod 93, a buffer piston 94, a first cavity 95, a floating piston 96, and a second cavity 97. One end of the upper fixed frame 91 is fixedly connected to the scraper 5, and the other end is slidably connected to the pressing rod 93. The other end of the pressing rod 93 is fixedly connected to the buffer piston 94. The cylinder includes a first cavity 95 and a second cavity 97. The first cavity 95 is smaller than the second cavity 97, and the first cavity 95 and the second cavity 97 are connected. The buffer piston 94 is slidably connected to the first cavity 95, and the floating piston 96 is slidably connected to the second cavity 97. One end of the lower fixed frame 90 is fixedly connected to the frame 1, and the other end is fixedly connected to the cylinder. The first cavity 95 and the second cavity 97 are provided with an air inlet 99 and an air outlet 98. The air inlet 99 and the air outlet 98 are provided with one-way valves.

[0032] The support shaft 71 of the support roller 6 is provided with a through hole, and the air outlet 98 is connected to the through hole of the support shaft 71. When the vibration mechanism 8 vibrates, the damping mechanism 9 generates a large amount of heat energy, causing hot air to exit through the air outlet 98. Since the air outlet 98 is connected to the support shaft 71, the hot air enters the interior of the support roller 6, providing a simple heating effect. This prevents the film on the support roller 6 from freezing and adhering, and the film coating effect is better after heat preservation.

[0033] It also includes an air storage tank 10 and a lifting cylinder 11. The air outlet 98 and the through hole are connected through the air storage tank 10. A pressure valve 14 is provided at the connection between the air storage tank 10 and the through hole. The lifting cylinder 11 includes a lifting cylinder 11 body, a reset member 13 and a piston rod 12. The lifting cylinder 11 body is connected to the air storage tank 10. One end of the piston rod 12 is slidably connected to the lifting cylinder 11 body and the other end is fixedly connected to the support shaft 71. The lifting cylinder 11 body is fixedly connected to the frame 1. One end of the reset member 13 is fixedly connected to the piston rod 12 and the other end is fixedly connected to the lifting cylinder 11 body.

[0034] When not in use, the piston rod 12 remains closed under the action of the reset member 13, and the support roller 6 is also in a higher position. This prevents damage to the film on the support roller 6 when the operator moves or drags it. When needed, the operator activates the vibration mechanism 8, which begins to vibrate. The hot air produced by the damping mechanism 9 enters the air storage tank 10 through the air outlet 98, and then enters the lifting cylinder 11, causing the piston rod 12 to extend and the support roller 6 to extend and contact the concrete. As more and more hot air enters the air storage tank 10, the pressure in the air storage tank 10 increases. When a certain level is reached, the pressure valve 14 opens, allowing the hot air in the air storage tank 10 to flow into the support roller 6, heating and insulating the film on the support roller 6.

[0035] As attached Figure 2 As shown:

[0036] The limiting mechanism 7 includes a support shaft 71, a pressure plate 72, a slide rod 73, a baffle 74, a spring 75, and a pin 76. Support shafts 71 are welded to both ends of the scraper 5, and the support shafts 71 are rotatably connected to the frame 1. The right end of the frame 1 contacts the pressure plate 72, and a slide rod 73 is welded to the right end of the frame 1. The slide rod 73 is slidably connected to the pressure plate 72, and a baffle 74 is welded to the right end of the slide rod 73. The baffle 74 is slidably connected to the pressure plate 72, and a spring 75 is provided on the outer side of the slide rod 73. One end of the spring 75 is fixedly connected to the pressure plate 72, and the other end of the spring 75 is welded to the baffle 74. By setting... Spring 75 allows pressure plate 72 to automatically reset. A pin 76 is welded to the lower left side of pressure plate 72. Pin 76 is slidably connected to support shaft 71. By setting pin 76, support shaft 71 can be limited. By rotating scraper 5, and through the action of spring 75 on pressure plate 72, pin 76 is inserted into support shaft 71, thus limiting support shaft 71. This allows scraper 5 to be adjusted in angle during use, enabling the device to be tilted to a certain degree for use, making the device more adaptable and easier to use.

[0037] like Figure 1 , Figure 3 As shown:

[0038] The vibration mechanism 8 includes a housing 81, a motor 82, a lever 83, a connecting shaft 84, a stop bar 85, and a torsion spring 86. The housing 81 is welded to the upper end of the scraper 5. The motor 82 is fixedly installed on the upper end of the housing 81. The rotating shaft of the motor 82 passes through the housing 81 and is rotatably connected to the housing 81. The lever 83 is welded to the surface of the rotating shaft. The lever 83 contacts the stop bar 85. By setting the lever 83, the stop bar 85 can rotate. The connecting shaft 84 is welded to the inner wall of the housing 81. The stop bar is installed on the outer side of the connecting shaft 84 through a bearing. 85. A torsion spring 86 is provided on the outer side of the connecting shaft 84. One end of the torsion spring 86 is welded to the frame 1, and the other end of the torsion spring 86 is welded to the stop rod 85. By setting the torsion spring 86, the stop rod 85 can be easily reset. The motor 82 drives the lever 83 to rotate, so that the lever 83 hits the stop rod 85, causing the stop rod 85 to rotate and collide with the scraper 5. This causes the scraper 5 to vibrate during movement, which in turn allows the scraper 5 to compact the concrete. At the same time, it makes the film on the support roller 6 adhere more tightly to the concrete.

[0039] As attached Figure 1-5 As shown:

[0040] The specific implementation process of this invention is as follows: In use, adjust the support rod 2 and the ground tilt angle according to usage habits. Manually move the pressure plate 72 to separate it from the frame 1, thereby separating the pin 76 from the support shaft 71. Then rotate the scraper 5 so that its surface contacts and is parallel to the ground. Then release the pressure plate 72, and the spring 75 returns to its original position, causing the pin 76 to enter the support shaft 71, limiting the position of the support shaft 71 and fixing the angle between the scraper 5 and the frame 1. By rotating the scraper 5, and through the action of the spring 75 on the pressure plate 72, the pin 76 is inserted into the support shaft 71, thus fixing the angle between the scraper 5 and the frame 1. The support shaft 71 is limited, which allows the scraper 5 to be adjusted in terms of its angle of movement during use. This allows the device to be tilted to a certain degree during use, making the device more adaptable and easier to use. During use, the motor 82 is started, which drives the lever 83 to rotate. The lever 83 then strikes the stop bar 85, causing the stop bar 85 to rotate and collide with the scraper 5. This causes the scraper 5 to vibrate during movement, which in turn allows the scraper 5 to compact the concrete. At the same time, it makes the membrane on the support roller 6 adhere more tightly to the concrete.

[0041] By rotating the scraper 5 and acting on the pressure plate 72 through the spring 75, the pin 76 is inserted into the support shaft 71, which limits the support shaft 71. This allows the scraper 5 to be adjusted in terms of its angle of movement during use, so that the device can be tilted to a certain degree during use, making the device more adaptable and easier to use.

[0042] The motor 82 drives the lever 83 to rotate, causing the lever 83 to strike the stop bar 85, which in turn causes the stop bar 85 to rotate and collide with the scraper 5. This causes the scraper 5 to vibrate during its movement, which in turn allows the scraper 5 to compact the concrete. At the same time, it makes the film on the support roller 6 adhere more tightly to the concrete.

[0043] During the coating process, the vibration of the scraper 5 transmits the vibration force to the upper fixed frame 91. The up-and-down vibration of the upper fixed frame 91 causes the extrusion rod 93 to move up and down. The buffer piston 94 of the extrusion rod 93 moves up and down within the condensate-filled oil. Simultaneously, the change in space within the first chamber 95 also causes the floating piston 96 within the second chamber 97 to move up and down, compressing the air within the second chamber 97. This causes the gas to enter through the air inlet 99 and exit through the air outlet 98, converting mechanical energy into heat energy. This reduces the mechanical energy transmitted to the lower fixed frame 90, significantly reducing the vibration of the frame 1, and preventing the support roller 6 from being affected by the vibration mechanism 8.

[0044] When not in use, the piston rod 12 remains closed under the action of the reset member 13, and the support roller 6 is also in a higher position. This prevents damage to the film on the support roller 6 when the operator moves or drags it. When needed, the operator starts the vibration mechanism 8, which vibrates. The hot air produced by the damping mechanism 9 enters the air storage tank 10 through the air outlet 98, and then enters the lifting cylinder 11 through the air storage tank 10, causing the piston rod 12 to extend and the support roller 6 to extend and contact the concrete. As more and more hot air enters the air storage tank 10, the pressure in the air storage tank 10 increases. When the set value is reached, the pressure valve 14 opens, allowing the hot air in the air storage tank 10 to flow into the support roller 6, heating and insulating the film on the support roller 6. When the vibration mechanism 8 vibrates, the damping mechanism 9 generates a large amount of heat energy, causing hot air to exit through the air outlet 98. The air outlet 98 is connected to the support shaft 71, allowing hot air to enter the support roller 6 and provide a simple heating effect. This prevents the film on the support roller 6 from freezing and adhering, and the film coating effect is better after heat preservation.

[0045] The device utilizes the changes in air pressure and hydraulic pressure within the first cavity 95 and the second cavity 97 to convert the mechanical energy within the cylinder into heat energy, thereby reducing the vibration of the support roller 6 and making the support roller 6 more stable during film coating, and less prone to deviation.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications will not affect the effectiveness of the present invention or the practicality of the patent.
