Description

Technical Field

[0001] The invention relates to a polishing processing device, in particular to a polishing processing device for a steel wheel of a road roller, which is applied in the technical field of grinding steel wheels of road rollers. Background Art

[0002] A road roller, also known as a soil roller, is a road construction equipment that is divided into two types: steel wheel type and tire type. Grinding and polishing the steel wheel of a road roller is an important maintenance step, which helps to restore the smoothness of the steel wheel, reduce friction and wear, and thus extend the service life of the road roller.

[0003] The specification of Chinese invention patent CN202311388099.2 discloses "A device for grinding and processing the roller wheel of a road roller". Through the cooperation between the driving switching mechanism and the maintenance mechanism, different processing methods are realized by switching, instead of manual hand-held processing, so that small problems such as rust or small dents on the surface of the roller wheel can be ground, thinned and maintained.

[0004] During the processing and maintenance of the steel wheel of the road roller, the defects on the surface of the steel wheel need to be repaired by welding. The welding marks protrude outward. If the protruding marks are not polished in advance, it will affect the overall polishing effect and polishing efficiency of the steel wheel. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the protruding marks after welding affect the overall polishing and grinding effect of the steel wheel and the polishing and grinding efficiency of the steel wheel.

[0006] In order to solve the above problems, the present invention provides a polishing processing device for a steel wheel of a road roller, comprising a base, both ends of the bottom of the base are rotatably connected to drive roller shafts, a steel wheel cylinder is placed on the top of the two drive roller shafts, one end of the base is hinged to a processing flip frame, and the top of the processing flip frame close to the steel wheel cylinder is fixedly connected to a polishing abrasive piece;

[0007] A movable rail is fixedly connected to the top of the processing turnover frame, and a designated grinder is slidably connected to the top of the movable rail. The designated grinder corresponds to the steel wheel drum, and a resistance turning pad is equidistantly hingedly arranged at one end of the movable rail close to the steel wheel drum. A pressure detection module is fixedly connected between the bottom of the resistance turning pad and the movable rail, and the output end of the pressure detection module is connected to the movable rail.

[0008] In the above-mentioned polishing processing device for the steel wheel of the road roller, the pressure detection module obtains position information by the resistance pad contacting the convex trace on the surface of the steel wheel cylinder, and the designated grinder on the movable rail moves to the designated position for grinding, which effectively improves the local grinding effect of the steel wheel of the road roller, facilitates the subsequent overall polishing of the steel wheel of the road roller, and effectively improves the polishing effect of the steel wheel of the road roller.

[0009] As a further improvement of the present application, one end of each of the two driving rollers is fixedly connected to a driving unit, and the two driving units have opposite rotation directions. Switching the driving units to drive the driving rollers facilitates changing the rolling direction of the steel drum.

[0010] As a further improvement of the present application, the length of the resistance pad is smaller than the length of the grinding shaft of the designated grinder, and a connecting piece is fixedly connected between the bottoms of two adjacent resistance pads, and the connecting piece is made of elastic plastic, which facilitates the designated grinder to cover the detection area of ​​the resistance pad, thereby effectively improving the regional grinding and polishing effect of the designated grinder.

[0011] As a further improvement of the present application, a fixed top plate is fixedly connected to the bottom of the movable rail, and the fixed top plate extends out of the movable rail at one end close to the steel wheel drum, and the extended end of the fixed top plate contacts the bottom end of the resistance flip pad. The fixed top plate is utilized to provide support for the resistance flip pad, thereby effectively preventing the resistance flip pad from excessive flipping, thereby protecting the pressure detection module.

[0012] As another improvement of the present application, a buffer pad is fixedly connected to the bottom of the contact end of the resistance flip pad and the fixed top plate, and the lower surface of the buffer pad is bonded to the fixed top plate. The buffer pad is used to buffer the flipping of the resistance flip pad, thereby providing pressure action space for detection by the pressure detection module.

[0013] As another improved supplement of the present application, both ends of the processing turnover frame are fixedly connected to side frames, and a cleaning brush plate is fixedly connected between the top ends of the two side frames. The bottom end of the cleaning brush plate corresponds to the steel wheel cylinder. The cleaning brush plate is used to clean the rolling steel wheel cylinder to facilitate the subsequent polishing processing of the steel wheel cylinder.

[0014] As another improvement supplement of the present application, the bottom of the cleaning brush plate is fixedly connected to a guide shaft, the top of the designated grinder is fixedly connected to a vertical brush plate, the top of the vertical brush plate is sleeved with the guide shaft, and during the horizontal movement of the designated grinder, the vertical brush plate is driven to clean the steel wheel barrel horizontally, further improving the cleaning effect of the steel wheel barrel surface, thereby effectively improving the polishing effect of the steel wheel barrel.

[0015] As another improvement of the present application, the contact surfaces of the cleaning brush plate and the vertical brush plate with the steel wheel drum are fixedly connected with brush pads, and the brush pads are made of wear-resistant rubber material. The cleaning brush plate and the vertical brush plate clean the surface of the steel wheel drum through the brush pads, thereby effectively improving the cleaning effect of the steel wheel drum surface.

[0016] As another improvement supplement of the present application, the bottom end of the vertical brush plate is slidably connected to the upper surface of the resistance flip pad, and the bottom end of the vertical brush plate is fixedly connected to an electromagnet block. During the lateral movement of the vertical brush plate, the electromagnet block is utilized to absorb and clean the wear debris on the resistance flip pad, thereby effectively preventing the wear debris from affecting the flipping movement of the resistance flip pad.

[0017] As another improvement in the present application, a blocking rib is fixedly connected to the top of the contact end of the resistance pad and the steel wheel drum, and the blocking rib is in contact with the lower surface of the electromagnet block. The blocking rib is utilized to prevent the wear debris on the resistance pad from sliding downward, thereby effectively preventing the wear debris from affecting the flipping movement of the resistance pad.

[0018] In summary, the present invention drives the steel wheel drum to roll by driving the roller shaft, and the steel wheel drum rolls and contacts the polishing abrasive for grinding and polishing. Before the steel wheel drum rolls and polishes, it first contacts the resistance pad, and the convex trace on the steel wheel drum squeezes the resistance pad to flip downward, and the pressure detection module is squeezed to obtain the position information of the convex trace. The designated grinder on the mobile rail moves to the designated position to grind the trace, which effectively improves the local grinding effect of the steel wheel of the roller, thereby effectively avoiding the convex trace from affecting the overall polishing of the steel wheel of the roller, and effectively improving the polishing effect and polishing efficiency of the steel wheel of the roller.

[0031] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] Figure 1-2 The figure shows a polishing processing device for a steel wheel of a road roller, comprising a base 1, both ends of the bottom of the base 1 are rotatably connected with driving roller shafts 101, a steel wheel drum 2 is placed on the top of the two driving roller shafts 101, one end of the base 1 is hinged with a processing flip frame 102, the top of the processing flip frame 102 close to the steel wheel drum 2 is fixedly connected with a polishing abrasive 103, one end of the two driving roller shafts 101 is fixedly connected with a driving unit 104, the two driving units 104 rotate in opposite directions, and switching the driving unit 104 to drive the driving roller shaft 101 is convenient for changing the rolling direction of the steel wheel drum 2;

[0034] The steel wheel drum 2 is placed on the base 1, and the driving roller 101 is used to provide support for the steel wheel drum 2. The driving unit 104 is started to drive the driving roller 101 to rotate, so that the steel wheel drum 2 rolls in the direction of the polishing abrasive 103. The steel wheel drum 2 is ground and polished during the rolling process. Another driving unit 104 is switched to drive the driving roller 101 to achieve reverse rolling of the steel wheel drum 2, and the grinding progress of the steel wheel drum 2 is adjusted to facilitate multiple grinding and polishing of local areas of the steel wheel drum 2.

[0035] Figure 1-5 As shown, a movable rail 3 is fixedly connected to the top of the processing turning frame 102, and a designated grinder 301 is slidably connected to the top of the movable rail 3. The designated grinder 301 corresponds to the steel wheel drum 2. A resistance turning pad 302 is equidistantly hingedly arranged at one end of the movable rail 3 close to the steel wheel drum 2. A pressure detection module 303 is fixedly connected between the bottom of the resistance turning pad 302 and the movable rail 3. The output end of the pressure detection module 303 is connected to the movable rail 3. The length of the resistance turning pad 302 is less than the grinding shaft length of the designated grinder 301, and a connecting piece 304 is fixedly connected between the bottoms of two adjacent resistance turning pads 302. The connecting piece 304 is made of elastic plastic, which is convenient for the designated grinder 301 to cover the detection area of ​​the resistance turning pad 302, and effectively improves the regional grinding and polishing effect of the designated grinder 301.

[0036] Before the rolling polishing process of the steel wheel drum 2, it first contacts the resistance turning pad 302. The convex mark on the steel wheel drum 2 squeezes the resistance turning pad 302 to flip downward, and the pressure detection module 303 is squeezed to obtain the position information of the convex mark. The designated grinder 301 on the movable rail 3 moves to the designated position, and the steel wheel drum 2 rolls in the opposite direction to contact the designated grinder 301 for local mark grinding, which effectively improves the local grinding effect of the roller steel wheel, thereby effectively avoiding the convex mark from affecting the overall polishing of the roller steel wheel, and effectively improving the polishing effect and polishing efficiency of the roller steel wheel.

[0037] Figure 3-5 As shown, a fixed top plate 305 is fixedly connected to the bottom of the movable rail 3, and the fixed top plate 305 is close to one end of the steel wheel drum 2 and extends out of the movable rail 3, and the extended end of the fixed top plate 305 is in contact with the bottom end of the abutting turning pad 302, and the fixed top plate 305 is used to provide support for the abutting turning pad 302, effectively avoiding excessive turning of the abutting turning pad 302, thereby protecting the pressure detection module 303, and a buffer pad 306 is fixedly connected to the bottom of the contact end of the abutting turning pad 302 and the fixed top plate 305, and the lower surface of the buffer pad 306 is bonded to the fixed top plate 305, and the buffer pad 306 is used to buffer the turning of the abutting turning pad 302, thereby providing a pressure action space for the detection of the pressure detection module 303;

[0038] The fixed top plate 305 is used to provide support for the resistance turning pad 302 to prevent the resistance turning pad 302 from over-turning, thereby preventing the pressure detection module 303 from being over-extruded and damaged. At the same time, the buffer pad 306 is used to buffer the turning of the resistance turning pad 302. The buffering interval of the buffer pad 306 provides pressure action space for the detection of the pressure detection module 303.

[0039] The second implementation method:

[0040] Compared with the first embodiment, this embodiment mainly adds a cleaning brush plate 401 and a vertical brush plate 403. The specific newly added structure is as follows, and the remaining structure is consistent with the first embodiment.

[0041] Figure 1 and Figure 6-8As shown, both ends of the processing turnover frame 102 are fixedly connected to the side frames 4, and a cleaning brush plate 401 is fixedly connected between the tops of the two side frames 4. The bottom end of the cleaning brush plate 401 corresponds to the steel wheel cylinder 2. The cleaning brush plate 401 is used to clean the rolling steel wheel cylinder 2, which is convenient for the subsequent polishing of the steel wheel cylinder 2. The bottom of the cleaning brush plate 401 is fixedly connected to the guide shaft 402, and the top of the designated grinder 301 is fixedly connected to the vertical brush plate 403. The top of the vertical brush plate 403 is sleeved with the guide shaft 402. The designated grinder 301 During the horizontal movement, the vertical brush plate 403 is driven to clean the steel wheel drum 2 horizontally, further improving the cleaning effect of the steel wheel drum 2 surface, thereby effectively improving the polishing effect of the steel wheel drum 2. The contact surfaces of the cleaning brush plate 401 and the vertical brush plate 403 with the steel wheel drum 2 are fixedly connected with a brush pad 404, and the brush pad 404 is made of wear-resistant rubber material. The cleaning brush plate 401 and the vertical brush plate 403 clean the surface of the steel wheel drum 2 through the brush pad 404, effectively improving the cleaning effect of the surface of the steel wheel drum 2;

[0042] During the rolling of the steel wheel drum 2, the cleaning brush plate 401 cleans the surface of the rolling steel wheel drum 2. During the horizontal movement of the designated grinder 301, the vertical brush plate 403 is driven to clean the steel wheel drum 2 horizontally, thereby further improving the surface cleaning effect of the steel wheel drum 2 and effectively improving the grinding and polishing effect of the steel wheel drum 2.

[0043] Figure 1 and Figure 7-10 As shown, the bottom end of the vertical brush plate 403 is slidably connected to the upper surface of the friction turning pad 302, and the bottom end of the vertical brush plate 403 is fixedly connected to an electromagnet block 405. During the horizontal movement of the vertical brush plate 403, the electromagnet block 405 is used to absorb and clean the wear debris on the friction turning pad 302, effectively preventing the wear debris from affecting the flipping movement of the friction turning pad 302. The top of the contact end of the friction turning pad 302 and the steel wheel drum 2 is fixedly connected with a blocking rib 406, which contacts the lower surface of the electromagnet block 405. The blocking rib 406 is used to prevent the wear debris on the friction turning pad 302 from sliding downward, effectively preventing the wear debris from affecting the flipping movement of the friction turning pad 302.

[0044] When the steel wheel barrel 2 is locally ground, the grinding chips fall onto the resistance turning pad 302. The blocking rib 406 is used to prevent the grinding chips on the resistance turning pad 302 from sliding downward, thereby effectively preventing the grinding chips from entering between the resistance turning pad 302 and the steel wheel barrel 2 and affecting the flipping movement of the resistance turning pad 302. Subsequently, during the horizontal movement of the designated grinder 301, the electromagnet block 405 at the bottom end of the vertical brush plate 403 adsorbs and cleans the grinding chips on the resistance turning pad 302. When the vertical brush plate 403 moves to the two ends of the moving rail 3, the electromagnet block 405 stops generating magnetic force, causing the grinding chips to fall off, thereby effectively improving the cleaning effect of the grinding chips, thereby effectively preventing the grinding chips from affecting the flipping movement of the resistance turning pad 302.

[0045] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
