Description

Technical Field

[0001] The invention relates to the field of roughening machines, in particular to a concrete structural surface roughening machine for roads and bridges. Background Art

[0002] A roughing machine is a tool similar to an "axe" that processes the surface of the completed main structure to make the construction surfaces of the two construction stages firmly bonded. Usually, the roughing machine is used in cast-in-place concrete structures. After the cast-in-place slab is poured, it is necessary to roughen it before pouring the next layer to make the concrete firmly bonded. Therefore, the "roughing machine" is generally also called the "concrete roughing machine".

[0003] The roughening process will inevitably produce a large amount of debris, dust, etc. If they cannot be cleaned up, it will affect the bonding strength between the roughened surface and other cast surfaces. In the actual construction process, the cleaning of these debris, dust, etc. either relies on manual cleaning or uses additional cleaning equipment for secondary treatment. During manual cleaning, workers need to work in a harsh environment full of dust. Not only is the labor intensity high, it is easy to cause health problems such as respiratory diseases, but also affected by human factors. The cleaning effect is uneven, and it is difficult to ensure that there is no residual debris on the roughened surface. If other cleaning equipment is used, although it can improve the cleaning efficiency to a certain extent, it will undoubtedly increase the equipment investment cost. At the same time, additional operators are required, making the entire roughening process more complicated and cumbersome, further increasing the labor cost investment. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0026] Example 1 See also Figures 1 to 8 The present invention provides a concrete structure surface roughening machine for roads and bridges, comprising a casing 1, four corners of the casing 1 are rotatably provided with a walking wheel, a push rod is fixedly provided at the rear of the casing 1, a roughening mechanism 2 for roughening the concrete structure surface is provided in the casing 1, and the roughening mechanism 2 is located at the front of the casing 1; A set of purge mechanisms 3 and a driving mechanism 4 for driving the purge mechanism 3 and the chiseling mechanism 2 are respectively arranged on both sides of the casing 1; The driving mechanism 4 is started, and the power is transmitted to the chiseling mechanism 2 and the blowing mechanism 3, so that they start to work. The chiseling mechanism 2 performs actions such as chiseling and grinding on the concrete structure surface at the front of the casing 1 to break the floating slurry and uneven parts on the concrete surface to create a rough surface; At the same time, the purge mechanisms 3 on both sides work synchronously to blow out strong airflows to blow the debris and dust generated during the chiseling process to the middle of the casing 1, so that the debris and dust are concentrated in the middle of the casing 1; A vacuum cleaner 5 is fixedly arranged on the casing 1 , and an air inlet of the vacuum cleaner 5 is connected to a dust collection bin 6 through a pipeline. The dust collection bin 6 is located at the rear middle of the casing 1 .

[0027] The construction workers push the whole chiseling machine to move along the concrete structure surface, and the dust generated by chiseling and blowing is sucked into the dust suction bin 6 in the rear middle, so that the chiseling machine does not need to manually clean the debris and dust on the ground after chiseling, thereby improving the practicability of the device.

[0028] The haircutting mechanism 2 comprises a bearing seat 7 slidably arranged on both sides of the housing 1, a rotating shaft 10 is rotatably arranged in the bearing seat 7, and a plurality of groups of haircutting units 11 are arranged on the rotating shaft 10; A screw rod 8 is fixedly disposed on each bearing seat 7 , and a knob 9 is threadedly connected to the screw rod 8 . The knob 9 is rotatably connected to the housing 1 .

[0029] Furthermore, scale marks are set on the housing 1, through which it can be observed whether the positions of the two bearing seats 7 are aligned, so as to ensure that the force of the subsequent chiseling operation is uniform and avoid the situation of excessive or insufficient local chiseling; According to the specific roughening requirements of the concrete structure surface of the road and bridge, the position of the bearing seat 7 is adjusted to achieve the specific requirements of the required roughening depth and roughness. If the roughening depth needs to be deepened, the bearing seat 7 is moved down appropriately by rotating the knob 9; conversely, if only a shallow roughening effect is required, the knob 9 is rotated in the opposite direction to move the bearing seat 7 up. Each adjustment is precisely controlled according to the scale mark to allow the roughening mechanism 2 to achieve the ideal operating parameters.

[0030] Each group of chiseling units 11 includes a mounting frame 12 slidably arranged on the housing 1, the mounting frame 12 is rotatably connected to the rotating shaft 10, a driving bevel gear 13 is rotatably arranged on the mounting frame 12, the driving bevel gear 13 is fixedly connected to the rotating shaft 10, one side of the driving bevel gear 13 is meshed with a driven bevel gear 14, and the driven bevel gear 14 is rotatably arranged on the mounting frame 12; A chiseling machine head 15 is rotatably arranged on the mounting frame 12 , and the chiseling machine head 15 is fixedly connected to the driven bevel gear 14 .

[0031] When the driving mechanism 4 is started, power is transmitted through the rotating shaft 10. Since the active bevel gear 13 is fixed on the rotating shaft 10, it rotates together with the rotating shaft 10. Relying on the meshing relationship between the bevel gears, the active bevel gear 13 drives the driven bevel gear 14 to rotate, thereby driving the rotation of the chiseling head 15. The rotating chiseling head 15 evenly chisels the surface to be chiseled.

[0032] The chiseling machine head 15 includes a chiseling frame 16, which is "Y"-shaped, and the interval angles of each branch are the same. A roller 17 is rotatably set on each branch, and a plurality of protrusions are set on the outer wall of the roller 17. The protrusions on the roller 17 are conical and evenly distributed on the roller 17.

[0033] When the driven bevel gear 14 rotates, the chiseling frame 16 rotates accordingly, driving the three rollers 17 to rotate synchronously. The conical protrusions on the rollers 17 contact the concrete surface, exerting continuous impact and scraping forces on the concrete surface. The conical protrusions can effectively break the surface slurry of the concrete. Since the three rollers 17 are distributed at specific angles, they can create uniform and multi-angle rough textures on the concrete surface, thereby improving the subsequent bonding effect between new and old concrete.

[0034] The purge mechanism 3 includes an air distribution pipe 18 rotatably arranged in the casing 1, a plurality of purge heads 19 are provided on the air distribution pipe 18, a rotary joint is provided at one end of the air distribution pipe 18, an air inlet pipe 20 is connected to the rotary joint, and the air inlet pipe 20 is connected to the exhaust port of the vacuum cleaner 5.

[0035] When the chiseling operation starts synchronously, the vacuum cleaner 5 will also be started. While the vacuum cleaner 5 is sucking dust, the airflow will be discharged from its exhaust port. This airflow will enter the air distribution pipe 18 along the air inlet pipe 20, and the plurality of purge heads 19 on the air distribution pipe 18 will blow airflow into the housing 1. The airflow blown by the purge heads 19 can cover a large area on both sides of the housing 1, and the debris and dust generated during the chiseling process will be blown to the middle of the housing 1. The gas discharged by the vacuum cleaner 5 has a certain amount of energy, mainly airflow pressure. Reusing this part of the gas can reduce additional energy consumption. For example, by reusing this part of the gas to drive the purge mechanism 3, there is no need to configure a power source for the purge mechanism 3 separately, such as an additional fan, thereby reducing the overall energy consumption and cost of the equipment. At the same time, it can also reduce exhaust gas emissions. The gas discharged by the vacuum cleaner 5 may contain a small amount of dust particles. If it is discharged directly into the atmosphere, the content of suspended particulate matter in the air will increase. By reusing this part of the gas, for example, for blowing away the debris generated by roughening, these dust particles can be better controlled within the construction area and processed again by subsequent dust collection devices, effectively reducing the pollution to the atmospheric environment around the construction site.

[0036] A fixed sleeve 21 is fixedly arranged outside the housing 1, a driven sleeve 22 is rotatably arranged inside the fixed sleeve 21, and a spiral guide groove 23 is provided on the side wall of the driven sleeve 22; A driving shaft 24 is rotatably disposed in the driven sleeve 22, and a curved groove 25 is provided on the side wall of the driving shaft 24; A horizontal slide groove is provided on the inner wall of the fixed sleeve 21, a slider 26 is slidably arranged in the slide groove, a guide rod is fixedly arranged on the slider 26, and the guide rod slides in the curved groove 25 and the guide groove 23; A control arm 27 is fixedly disposed at one end of the driven sleeve 22 , and a swing arm 28 is fixedly disposed at one end of the air distribution pipe 18 . The swing arm 28 and the control arm 27 are connected via a connecting rod 29 .

[0037] When the driving shaft 24 rotates, the guide rod in the slide groove is driven to move. Under the joint action of the curved groove 25 and the slide groove, the slider 26 moves back and forth along the slide groove. While the slider 26 moves, it drives the driven sleeve 22 to make a reciprocating rotational motion. The driven sleeve 22 reciprocates, and the control arm 27 fixed at one end thereof also swings back and forth accordingly. The control arm 27 is connected to the swing arm 28 at one end of the air distribution pipe 18 through the connecting rod 29. The swing arm 28 is driven to rotate by the connecting rod 29, so that the air distribution pipe 18 performs an undulating and swinging motion with the rotary joint as the axis. During the haircutting operation, the many blowing heads 19 on the air distribution pipe 18 can blow airflow toward both sides of the casing 1 at multiple angles and over a large area, and efficiently blow the debris and dust generated by the haircutting toward the middle of the casing 1, so that the haircutting machine does not need to manually clean the debris and dust on the ground after haircutting, thereby improving the practicability of the device.

[0038] The driving mechanism 4 includes a driving motor 30 fixedly arranged at the front of the housing 1, a driving pulley 31 is coaxially fixedly arranged on the motor shaft of the driving motor 30, a driven pulley 32 is coaxially fixedly arranged at one end of the rotating shaft 10, and the driven pulley 32 is connected to the driving pulley 31 through a transmission belt 33; A tensioning wheel is also provided on the housing 1, and the transmission belt 33 passes around the tensioning wheel; An input bevel gear 34 is fixedly disposed at each end of the rotating shaft 10 . An output bevel gear 35 is meshed with each input bevel gear 34 . The output bevel gear 35 is coaxially fixed to a driving shaft 24 on the same side.

[0039] The driving motor 30 is turned on, and the motor shaft drives the coaxially fixed driving pulley 31 to rotate synchronously. Since the driving pulley 31 and the driven pulley 32 are connected by the transmission belt 33, under the action of the transmission belt 33, the power is transmitted to the driven pulley 32, and then the rotating shaft 10 is driven to rotate. As the rotating shaft 10 rotates, the input bevel gears 34 fixed at both ends thereof also rotate accordingly. Relying on the meshing relationship between the bevel gears, the input bevel gear 34 drives the output bevel gear 35 to rotate, and the output bevel gear 35 drives the driving shaft 24 on the same side to start rotating, so that the air distribution pipe 18 performs an undulating and swinging motion with the rotary joint as the axis. During the roughening operation, the many purge heads 19 on the air distribution pipe 18 can blow airflow toward both sides of the casing 1 at multiple angles and over a large area.

[0040] When the present invention is used, the driving mechanism 4 is started, and the power is transmitted to the chiseling mechanism 2 and the blowing mechanism 3, so that they start to work. The chiseling mechanism 2 performs actions such as chiseling and grinding on the concrete structure surface at the front of the casing 1 to break the floating slurry and uneven parts on the concrete surface to create a rough surface; At the same time, the purge mechanisms 3 on both sides work synchronously to blow out strong airflows to blow the debris and dust generated during the chiseling process to the middle of the casing 1, so that the debris and dust are concentrated in the middle of the casing 1; The construction workers push the whole chiseling machine to move along the concrete structure surface, and the dust generated by chiseling and blowing is sucked into the dust suction bin 6 in the rear middle, so that the chiseling machine does not need to manually clean the debris and dust on the ground after chiseling, thereby improving the practicability of the device.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
