This device possesses more comprehensive cleaning characteristics, enabling efficient and thorough cleaning of impurities within the joint surface.

Description

Technical Field

[0001] This utility model relates to the field of construction joint surface cleaning, and in particular to a cleaning device for concrete construction joint surfaces. Background Technology

[0002] Construction joints in concrete refer to the joints formed between concrete poured in stages due to design requirements or construction needs. Especially during the paving of concrete pavements, construction joints often remain in the middle of the pavement. Therefore, in the later stages of construction, the construction joint surface needs to be filled. Before filling, various kinds of dust and impurities are easily left in the construction joint, so it is necessary to clean it. As shown in the concrete pavement joint cleaning machine disclosed on the China Patent Network (publication announcement number CN219992149U), this type of device uses the sway adjustment of the moving mechanism to move the joint cleaning blade wheel of the joint cleaning mechanism downward, adjust the cleaning height of the joint cleaning blade wheel, and then use the drive of the joint cleaning blade wheel to clean the joint surface.

[0003] However, the concrete construction joint cleaning devices disclosed in the aforementioned patents and those currently used in the market still have some shortcomings: While existing methods using a single cleaning component to clean construction joints have good joint cleaning characteristics, the cleaned impurities still accumulate at the joint openings, causing them to easily fall back into the joints, resulting in a less than ideal cleaning effect. Therefore, those skilled in the art have provided a concrete construction joint cleaning device to solve the problems mentioned in the background art. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5This utility model provides a technical solution for a concrete construction joint surface cleaning device: A concrete construction joint surface cleaning device includes a trolley frame 1, a cleaning component is provided inside the frame of the trolley frame 1, and lifting guide rails 8 are provided symmetrically on both sides of the upright of the trolley frame 1. The lifting guide rails 8 are fixedly connected to the cleaning component, and a lifting screw 9 is provided between two adjacent sets of lifting guide rails 8. The lifting screw 9 is fixedly connected to the cleaning component. The lifting guide rail 8 is provided with a lifting slide platform fixedly connected to the cleaning component along its slide rail direction, and the lifting screw 9 is provided with a lifting sleeve fixedly connected to the cleaning component along its axial direction. When cleaning the concrete construction joint surface, the lifting guide rail 8 is used as a track slide platform. Driven by the lifting screw 9, the cleaning component is driven to move up and down, and the cleaning component in the cleaning component is adjusted to bring the cleaning component closer to the concrete construction joint surface for cleaning.

[0020] It should be noted that a drive assembly for driving the lifting screws 9 is provided above the trolley frame 1. The drive assembly includes a housing 3 located at the top of the trolley frame 1. Inside the housing 3, there is a drive shaft 12 directly opposite the two sets of lifting screws 9. A first motor 13 is located inside the housing 3, offset from the drive shaft 12. The output shaft of the first motor 13 is equipped with a first driving bevel gear 14. A first driven bevel gear 15 meshing with the first driving bevel gear 14 is located in the middle of the shaft of the drive shaft 12. A second driven bevel gear 10 is located at the top of the shafts of both sets of lifting screws 9. The shaft has a second driving bevel gear 11 at each end that meshes with the second driven bevel gear 10. During the lifting and lowering movement of the cleaning assembly, the first motor 13 is controlled to work, driving the first driving bevel gear 14 to rotate. The meshing of the first driving bevel gear 14 with the first driven bevel gear 15 drives the drive shaft 12 to rotate. During the rotation of the drive shaft 12, the second driving bevel gear 11 is driven to rotate. The meshing of the second driving bevel gear 11 with the second driven bevel gear 10 drives the lifting screw 9 to rotate, generating the driving force to drive the lifting and lowering movement of the cleaning assembly.

[0021] In addition, the base frame of the trolley frame 1 is equipped with wheels 2 in a symmetrical manner on both sides, and a pusher 4 is provided on one side of the trolley frame 1. After the cleaning components of the cleaning assembly are adjusted, the cleaning device can be driven along the construction joint surface by using the wheels 2 as a support carrier and the pusher 4 as a pusher to clean the construction joint surface.

[0022] As a further embodiment of this solution, the cleaning assembly includes a housing 5 disposed inside the trolley frame 1. A cleaning roller 7 is disposed on one side of the housing 5, and an outer cover 22 is disposed on the outside of the cleaning roller 7 to prevent impurities from being thrown into the housing 5. A blower 6 is disposed in the middle of the housing 5, and a second motor 16 is disposed on the other side of the housing 5. The output shaft of the second motor 16 is provided with a drive belt 21 for driving the blower 6 and the cleaning roller 7. The output shaft of the second motor 16 is provided with a drive pulley 17, the impeller shaft of the blower 6 is provided with a first driven pulley 18, and the roller shaft of the cleaning roller 7 is provided with a second driven pulley 19. The drive pulley 17, the first driven pulley 18, and the second driven pulley 19 are connected. Equipped with a transmission belt 21, the second motor 16 is controlled to operate during the process of pushing the cleaning device along the construction joint surface, driving the drive pulley 17 to rotate. Then, under the tension transmission of the first driven pulley 18, the second driven pulley 19, and the tension pulley 20, the transmission belt 21 is driven to rotate, driving the first driven pulley 18 and the second driven pulley 19 to rotate synchronously. This, in turn, drives the blower 6 and the cleaning roller 7 to rotate synchronously. The operation of the blower 6 is used to perform air blowing on the construction joint surface, blowing out the impurities inside the construction joint surface. Then, the operation of the cleaning roller 7 is used to clean the construction joint surface again, while also sweeping the cleaned impurities to both sides of the joint surface, so that the impurities are away from the construction joint surface.

[0023] It should be noted that the cleaning roller 7 includes a roller body 71. A central roller brush 72 is provided in the middle of the roller surface of the roller body 71, and side roller brushes 73 are provided on both sides of the roller surface of the roller body 71. The side roller brushes 73 have a spiral structure, and the spiral brushes of the two sets of side roller brushes 73 are arranged opposite to the central roller brush 72. During the use of the cleaning roller 7, the central roller brush 72 is inserted into the construction joint surface. The impurities in the construction joint surface are cleaned out by the roller brush of the central roller brush 72. Furthermore, the side roller brushes 73 with spiral structures on both sides of the central roller brush 72 are swept away from the construction joint surface by the roller brushes on both sides of the joint surface as the central roller brush 72 rotates.

[0024] The working principle of this utility model is as follows: When cleaning the concrete construction joint surface, the center brush 72 of the cleaning roller 7 is aligned with the construction joint surface. Then, the first motor 13 is controlled to work, driving the combination of the first active bevel gear 14 and the first driven bevel gear 15 to mesh and drive the drive shaft 12 to rotate. During the rotation of the drive shaft 12, the combination of the second active bevel gear 11 and the second driven bevel gear 10 is driven to mesh and drive, which in turn drives the lifting screw 9 to rotate. The lifting guide rail 8 is used as a track slide to drive the cleaning component to move up and down. The blower 6 and the cleaning roller 7 in the cleaning component are adjusted to move up and down, so that the blower 6 and the cleaning roller 7 are close to the concrete construction joint surface. Then, the cleaning device is pushed along the construction joint surface by a pusher. During the movement, the second motor 16 is controlled to work, driving the combination of the driving pulley 17, the first driven pulley 18, the second driven pulley 19, and the transmission belt 21 to rotate. This drives the blower 6 and the cleaning roller 7 to rotate synchronously. The operation of the blower 6 blows the construction joint surface with air to blow out the impurities. Then, the operation of the cleaning roller 7 uses the central roller brush 72 to clean out the impurities in the construction joint surface. In addition, the side roller brushes 73 with spiral structures on both sides of the central roller brush 72 sweep the cleaned impurities to the sides of the joint surface as the central roller brush 72 rotates, moving the cleaned impurities away from the construction joint surface.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
