Abstract
Description
Technical Field
[0001] This invention belongs to the field of highway maintenance technology, specifically a highway maintenance concrete coating recycling device. Background Technology
[0002] Currently, concrete roads need to undergo a hydration and hardening process for a period of time after construction. If this hydration process is not completed and moisture is lost, it will result in incomplete hydration. On the one hand, the strength of the concrete road will not meet the standards, and on the other hand, shrinkage cracks will appear on the road surface, which will seriously endanger the stability of the road. Therefore, it is necessary to cover the surface of newly constructed concrete roads with plastic film. The plastic film prevents the moisture in the concrete from evaporating too quickly. Moreover, the plastic film can also insulate the road surface and prevent excessive temperature difference between the inside and outside of the concrete from causing temperature cracks.
[0003] In the existing technology, when covering the surface of a concrete road with plastic film, the presence of mud and debris on the concrete road surface can prevent the plastic film from making complete contact with the concrete road surface, resulting in an unsatisfactory covering effect. Furthermore, when the plastic film is recycled after the concrete road has been cured, it is easy for the plastic film to be damaged due to being too tightly attached to the concrete road surface, which in turn affects the subsequent use of the plastic film. Summary of the Invention
[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a highway maintenance concrete coating recycling device.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A highway maintenance concrete film recycling device includes a traveling support frame, a roll-up and unrolling assembly, a film pressing assembly, and an adjustable air blowing assembly. The winding and unwinding assembly is mounted on the side wall of the traveling support frame and is used for winding and unwinding the plastic film. The film pressing assembly is located on the left side of the traveling support and is used to press the plastic film onto the concrete road surface. The adjustable air blowing assembly is located inside the walking support. As the traveling support moves to the right along the concrete pavement, the adjustable air blowing assembly is used to blow air onto the concrete pavement located to the right of the traveling support. When the traveling support moves to the left along the concrete road surface, the adjustable air blowing assembly is used to blow air onto the concrete road surface located on the left side of the traveling support.
[0006] As a further improvement of the present invention: the take-up and unwinding assembly includes a roller and a motor. The motor is fixedly installed on the side wall of the traveling support. The roller is disposed inside the traveling support and is controlled by the motor to rotate in both directions. The plastic film is wound around the outside of the roller.
[0007] As a further improvement of the present invention: the pressing assembly includes a pressing rod and a flexible rolling layer, wherein the flexible rolling layer is arranged in a ring structure outside the pressing rod.
[0008] As a further improvement of the present invention: the adjustable air blowing assembly includes an air supply fan, an air delivery pipe, and an air blowing nozzle. The air supply fan is fixedly installed on the side wall of the traveling support. One end of the air supply pipe is rotatably connected to the air outlet of the air supply fan, and the other end extends to the inner side of the traveling support and is rotatably connected to the inner wall of the traveling support. The air supply pipe is located below the roller and distributed along the length of the roller. Several sets of air nozzles are provided, and several air nozzles are installed on the side wall of the air supply pipe and distributed at intervals along the length of the air supply pipe.
[0009] As a further improvement of the present invention: a locking sleeve is fixedly provided on the inner wall of the walking bracket, the locking sleeve is sleeved on the outside of the air supply pipe, and a locking bolt is threaded on the locking sleeve.
[0010] As a further improvement of the present invention: the traveling support is also provided with a lateral movement component. When the traveling support moves to the left along the concrete road surface, the lateral movement component drives the pressure bar and the flexible rolling layer away from the traveling support.
[0011] As a further improvement of the present invention: the lateral movement assembly includes a lateral movement hydraulic cylinder, a support plate, an elastic element, a telescopic rod, and a telescopic sleeve. The lateral hydraulic cylinder is fixedly installed on the inner wall of the traveling bracket. The support plate is connected to the output end of the lateral hydraulic cylinder. The telescopic rod is fixedly installed at the bottom of the support plate. The upper end of the telescopic sleeve is sleeved on the outside of the telescopic rod, and the lower end is connected to the pressure rod. One end of the elastic element is connected to the bottom of the support plate, and the other end is connected to the telescopic sleeve, which is used to provide elastic support for the telescopic sleeve.
[0012] As a further improvement of the present invention: an end block is fixedly provided at the bottom of the telescopic sleeve, and the end of the pressure rod is rotatably connected to the end block.
[0013] Compared with the prior art, the beneficial effects of the present invention are: In this embodiment of the invention, when it is necessary to cover a concrete pavement with plastic film, the traveling bracket can be placed on the upper part of the concrete pavement and driven to move to the right along the concrete pavement. At the same time, the unwinding and rewinding assembly unwinds the plastic film, and the pressing assembly presses the unwound plastic film onto the concrete pavement, thereby completing the plastic film covering operation. When it is necessary to recycle the plastic film on the concrete pavement, the traveling bracket can be driven to move to the left along the concrete pavement. At the same time, the unwinding and rewinding assembly rewinds the plastic film, so that the plastic film is rewound onto the unwinding and rewinding assembly. When the traveling bracket moves to the right along the concrete pavement, the adjustable air blowing assembly blows air onto the concrete pavement located to the right of the traveling bracket, thereby blowing away debris from the concrete pavement. To improve the film coating effect, when the traveling support moves to the left along the concrete road surface, an adjustable air blowing component blows air onto the concrete road surface located on the left side of the traveling support. At this time, the airflow blown by the adjustable air blowing component acts between the plastic film and the concrete road surface, thereby peeling the plastic film off the concrete road surface in advance. This allows the winding and unwinding components to better wind up the plastic film, avoiding excessive tension and breakage during the winding process. Compared with existing technologies, this method can clean the concrete road surface during plastic film coating to improve the coating effect, and can pre-peel the plastic film from the concrete road surface during plastic film recycling, thereby preventing the plastic film from breaking due to excessive tension during recycling.

Detailed Implementation
[0015] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.
[0016] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0017] Please see Figure 1 as well as Figure 2 This embodiment provides a highway maintenance concrete film recycling device, including a traveling support 10, a take-up and undo assembly 20, a film pressing assembly 30, and an adjustable air blowing assembly 50. The take-up and undo assembly 20 is disposed on the side wall of the traveling support 10 and is used to take up and undo the plastic film 60. The film pressing assembly 30 is disposed on the left side of the traveling support 10 and is used to press the plastic film 60 onto the concrete pavement 70. The adjustable air blowing assembly 50 is disposed inside the traveling support 10. When the traveling support 10 moves to the right along the concrete pavement 70, the adjustable air blowing assembly 50 is used to blow air onto the concrete pavement 70 located on the right side of the traveling support 10. When the traveling support 10 moves to the left along the concrete pavement 70, the adjustable air blowing assembly 50 is used to blow air onto the concrete pavement 70 located on the left side of the traveling support 10.
[0018] When it is necessary to cover the concrete pavement 70 with plastic film 60, the traveling bracket 10 can be placed on the concrete pavement 70 and driven to move to the right along the concrete pavement 70. At the same time, the unwinding assembly 20 unwinds the plastic film 60, and the pressing assembly 30 presses the unwound plastic film 60 onto the concrete pavement 70, thereby completing the film covering operation of plastic film 60. When it is necessary to recycle the plastic film 60 on the concrete pavement 70, the traveling bracket 10 can be driven to move to the left along the concrete pavement 70, and at the same time, the unwinding assembly 20 rewinds the plastic film 60, so that the plastic film 60 is rewound onto the unwinding assembly 20. The above describes the process when the traveling bracket 10 moves to the right along the concrete pavement 70. The adjustable air blowing assembly 50 blows air onto the concrete pavement 70 located on the right side of the traveling support 10, thereby blowing away debris from the concrete pavement 70 and improving the coating effect of the plastic film 60. When the traveling support 10 moves to the left along the concrete pavement 70, the adjustable air blowing assembly 50 blows air onto the concrete pavement located on the left side of the traveling support 10. At this time, the airflow blown by the adjustable air blowing assembly 50 acts between the plastic film 60 and the concrete pavement 70, thereby peeling the plastic film 60 off the concrete pavement 70 in advance, so that the winding assembly 20 can better wind up the plastic film 60 and avoid excessive tension on the plastic film 60 during winding, which could cause it to break.
[0019] Please see Figure 1 as well as Figure 2 In one embodiment, the take-up and unwind assembly 20 includes a roller 201 and a motor 202. The motor 202 is fixedly mounted on the side wall of the traveling support 10. The roller 201 is disposed inside the traveling support 10 and is controlled by the motor 202 to rotate in both directions. The plastic film 60 is wound around the outside of the roller 201.
[0020] When the traveling support 10 moves to the right along the concrete road surface 70, the motor 202 drives the roller 201 to rotate in the forward direction, thereby unwinding the plastic film 60 from the outside of the roller 201. The unwound plastic film 60 is pressed onto the upper part of the concrete road surface 70 by the film pressing assembly 30, realizing the automatic film covering operation of the plastic film 60. When the traveling support 10 moves to the left along the concrete road surface 70, the motor 202 drives the roller 201 to rotate in the reverse direction, thereby winding up the plastic film 60 on the concrete road surface 70, realizing the automatic recycling of the plastic film 60.
[0021] Please see Figure 1 as well as Figure 4 In one embodiment, the pressing assembly 30 includes a pressing rod 301 and a flexible rolling layer 302, wherein the flexible rolling layer 302 is arranged in an annular structure outside the pressing rod 301.
[0022] As the traveling support 10 moves to the right along the concrete road surface 70, the traveling support 10 drives the pressure bar 301 and the flexible rolling layer 302 to move synchronously. The flexible rolling layer 302 presses the plastic film 60, which is unrolled by the roller 201, onto the concrete road surface 70, so that the plastic film 60 adheres to the concrete road surface 70. When the flexible rolling layer 302 presses the plastic film 60 onto the concrete road surface 70, there is flexible contact between the flexible rolling layer 302 and the plastic film 60, which can effectively prevent the plastic film 60 from being damaged due to excessive pressure.
[0023] Please see Figure 2 as well as Figure 5 In one embodiment, the adjustable air blowing assembly 50 includes an air supply fan 501, an air delivery pipe 502, and air blowing nozzles 503. The air supply fan 501 is fixedly installed on the side wall of the traveling support 10. One end of the air delivery pipe 502 is rotatably connected to the air outlet end of the air supply fan 501, and the other end extends to the inner side of the traveling support 10 and is rotatably connected to the inner wall of the traveling support 10. The air delivery pipe 502 is located below the roller 201 and is distributed along the length direction of the roller 201. Several groups of air blowing nozzles 503 are provided, and several air blowing nozzles 503 are installed on the side wall of the air delivery pipe 502 and are spaced apart along the length direction of the air delivery pipe 502.
[0024] As the traveling support 10 moves to the right along the concrete road surface 70, several air nozzles 503 face the lower right side of the traveling support 10. At this time, the air supply fan 501 delivers air into the air supply pipe 502, and the air is then output from the air nozzles 503 and acts on the concrete road surface 70 located on the right side of the traveling support 10 to blow away debris, allowing the plastic film 60 to better adhere to the concrete road surface 70. When it is necessary to recycle the plastic film 60, the operator can rotate the air supply pipe 502 so that the air nozzles 503 face the lower left side of the traveling support 10. Then, the traveling support 10 moves to the left along the concrete road surface 70, and the air supply fan 501 continues to deliver air into the air supply pipe 502. The air is then output from the air nozzles 503 and acts on the concrete road surface 70 located on the left side of the traveling support 10, thereby peeling the plastic film 60 off the concrete road surface 70 in advance, so that the roller 201 can better reel in the plastic film 60.
[0025] Please see Figure 5 In one embodiment, a locking sleeve 101 is fixedly provided on the inner wall of the walking support 10. The locking sleeve 101 is sleeved on the outside of the air supply pipe 502, and a locking bolt 102 is threaded on the locking sleeve 101.
[0026] After rotating the air supply pipe 502 so that the air nozzles 503 are facing the lower left of the traveling support 10, the operator can tighten the locking bolt 102 so that the locking bolt 102 is screwed into the locking sleeve 101, thereby supporting the air supply pipe 502 and fixing the air supply pipe 502. This improves the stability of the air supply pipe 502 and the air nozzles 503, so that the airflow can better peel the plastic film 60 off the concrete pavement 70. It should be noted that when the air nozzles 503 are facing the lower right of the traveling support 10, the locking bolt 102 is also in a supporting state on the air supply pipe 502, so that the airflow output by the air nozzles 503 can stably blow the debris off the concrete pavement 70.
[0027] Since the flexible roller layer 302 is in a pressed state against the plastic film 60 after the plastic film 60 is coated, the portion of the plastic film 60 between the flexible roller layer 302 and the roller 201 has an inclined structure. Therefore, when the air nozzles 503 deliver airflow to the lower left, the airflow has difficulty passing under the flexible roller layer 302, thus preventing the early peeling of the plastic film 60. Based on this, please refer to... Figure 1 In one embodiment, the traveling support 10 is further provided with a lateral movement component 40. When the traveling support 10 moves to the left along the concrete road surface 70, the lateral movement component 40 drives the pressure rod 301 and the flexible rolling layer 302 away from the traveling support 10, so that a certain length of plastic film 60 adhering to the concrete road surface 70 always exists on the right side of the flexible rolling layer 302. When the air nozzle 503 delivers airflow to the lower left position, the airflow can act on the bottom of the plastic film 60 of this length, thereby peeling the plastic film 60 of this length off the concrete road surface 70, so that the roller 201 can smoothly recycle the plastic film 60.
[0028] Please see Figure 3 In one embodiment, the lateral movement assembly 40 includes a lateral movement hydraulic cylinder 401, a support plate 402, an elastic element 403, a telescopic rod 404, and a telescopic sleeve 405. The lateral movement hydraulic cylinder 401 is fixedly installed on the inner wall of the traveling bracket 10. The support plate 402 is connected to the output end of the lateral movement hydraulic cylinder 401. The telescopic rod 404 is fixedly installed at the bottom of the support plate 402. The upper end of the telescopic sleeve 405 is sleeved on the outside of the telescopic rod 404, and the lower end is connected to the pressure rod 301. One end of the elastic element 403 is connected to the bottom of the support plate 402, and the other end is connected to the telescopic sleeve 405, for providing elastic support to the telescopic sleeve 405.
[0029] When the traveling support 10 moves to the left along the concrete road surface 70, the support plate 402 can be moved by the lateral hydraulic cylinder 401. The support plate 402 drives the telescopic rod 404, telescopic sleeve 405, pressure rod 301, and flexible rolling layer 302 to move. The pressure rod 301 and flexible rolling layer 302 move away from the traveling support 10, thereby leaving a section of plastic film 60 adhering to the concrete road surface 70 between the flexible rolling layer 302 and the roller 201, so that it can be output through several air nozzles 503. The airflow can smoothly peel off the plastic film 60 in advance; when the traveling support 10 moves to the right along the concrete road surface 70 to carry out the film covering operation, the flexible rolling layer 302 and the core rod 301 can adapt to the undulation of the concrete road surface 70 and move up and down adaptively under the support of the elastic element 403. At the same time, the telescopic sleeve 405 moves up and down adaptively compared with the telescopic rod 404. The flexible rolling layer 302 can stably press the plastic film 60 onto the concrete road surface 70, thereby improving the film covering effect of the plastic film 60.
[0030] In one embodiment, the elastic element 403 can be a spring or a metal sheet, and there is no limitation on this.
[0031] Please see Figure 4 In one embodiment, an end block 406 is fixedly provided at the bottom of the telescopic sleeve 405, and the end of the pressure rod 301 is rotatably connected to the end block 406.
[0032] When the traveling support 10 moves to the right along the concrete road surface 70 to perform the film covering operation, the pressure bar 301 can rotate adaptively relative to the end block 406, thereby driving the flexible rolling layer 302 to roll adaptively along the concrete road surface 70, so as to realize the rolling film covering of the plastic film 60.
[0033] In one embodiment, the flexible rolling layer 302 can be a rubber layer or a silicone layer, and there is no limitation on this.
[0034] In one embodiment, the walking support 10 is provided with walking wheels at its bottom.
[0035] In this embodiment of the invention, when it is necessary to cover the concrete pavement 70 with plastic film 60, the traveling bracket 10 can be placed on the upper part of the concrete pavement 70 and driven to move to the right along the concrete pavement 70. At the same time, the unwinding assembly 20 unwinds the plastic film 60, and the pressing assembly 30 presses the unwound plastic film 60 onto the concrete pavement 70, thereby completing the film covering operation of plastic film 60. When it is necessary to recycle the plastic film 60 on the concrete pavement 70, the traveling bracket 10 can be driven to move to the left along the concrete pavement 70, and at the same time, the unwinding assembly 20 rewinds the plastic film 60, so that the plastic film 60 is rewound onto the unwinding assembly 20. When the traveling bracket 10 moves to the right along the concrete pavement 70, the adjustable air blowing assembly 50 blows air onto the concrete pavement 70 located to the right of the traveling bracket 10, thereby removing debris from the concrete pavement. To improve the film-covering effect of the plastic film 60, the adjustable air blowing component 50 blows air onto the concrete road surface 70 as the traveling support 10 moves to the left along the concrete road surface 70. At this time, the airflow blown by the adjustable air blowing component 50 acts between the plastic film 60 and the concrete road surface 70, thereby peeling the plastic film 60 off the concrete road surface 70 in advance. This allows the winding and unwinding component 20 to better wind up the plastic film 60, avoiding excessive tension and breakage during winding. Compared with the prior art, this method can clean the concrete road surface 70 during the film-covering process to improve the film-covering effect. When the plastic film 60 is recycled, it can be pre-peeled from the concrete road surface 70, thus preventing the plastic film 60 from breaking due to excessive tension during recycling.
[0036] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
