[0002] Highway guardrail is the main form of semi-rigid guardrail. It is a continuous structure with corrugated steel guardrail plates spliced ​​together and supported by main columns. It absorbs energy when vehicles collide with it, so it is not easily destroyed and can provide good protection for vehicles and passengers. Highway guardrails are made of round steel pipes, square steel pipes and corrugated steel plates due to different usage sections. During the production process, burrs are inevitable on the cross-section of the material. If the burrs cannot be polished clean, it will affect the appearance and safety of the guardrail.

[0003] When existing burr grinding equipment is used to grind high-speed guardrails, most of them use manual handheld grinding equipment to grind the guardrails with grinding wheels. During the process of contact and grinding between the grinding wheel and the guardrail, the guardrail is likely to transfer force to the grinding equipment, which not only wastes too much physical output of the workers, but also easily causes the grinding equipment to fall off, which is very dangerous. To this end, we provide an assembled highway guardrail burr grinding device to solve the above problems. Utility Model Content

The mounting plate 5 provides support for the installation of the limit plate 6 and the sliding frame 9. The limit plates 6 are symmetrically arranged in four groups on the front of the mounting plate 5. The four groups of limit plates 6 can be incompletely combined into a circular ring shape, which is convenient for applying guardrails of different shapes that need to be polished. By applying a rotational force to the threaded rods 7 threadedly connected to the inside of each limit plate 6, the threaded rods 7 can push the extrusion pads 8 arranged at the other end to extrude and position the guardrails of different shapes arranged inside the four groups of limit plates 6. The extrusion pads 8 are non-slip rubber pads. The extrusion pads 8 can increase the friction of the guardrails to avoid shaking of the guardrails in the clamping and polishing state. The sliding frame 9 is U-shaped. The sliding frame 9 provides installation support for the motor 11. The sliding frame 9 is movable through the interior of the mounting plate 5, and through the elastic action of the spring 10, by applying a pushing force to the No. 2 push rod 14 arranged at the top of the motor 11, the movement of the sliding frame 9 can cause the spring 10 to deform, thereby adjusting the use position of the grinding wheel 13.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, the utility model provides a technical solution: an assembled highway guardrail burr grinding device;

[0028] A control panel 2 is arranged on the back of the support frame 1, a push rod 3 is arranged on the back of the support frame 1, and the push rod 3 is located above the control panel 2, and a push rod 14 is arranged on the top of the motor 11, and the push rod 14 is a U-shaped rod.

[0029] The support frame 1 is one of the main supporting components of the guardrail burr grinding device. A universal wheel is provided at the bottom end of the support frame 1 to facilitate the transfer of the use position of the grinding device. The support frame 1 is electrically connected to the electrical components inside the grinding device through the control panel 2. The control panel 2 can control the operation of the grinding device. The No. 2 push rod 14 provides a pushing position for pushing the sliding frame 9 to move.

[0030] like Figure 3 and Figure 4 As shown, the utility model provides a technical solution: an assembled highway guardrail burr grinding device;

[0031] A motor 11 is arranged on the back of the sliding frame 9, a rotating shaft 12 is arranged at the output end of the motor 11, and the rotating shaft 12 movably passes through the front of the mounting plate 5, a grinding wheel 13 is detachably arranged on the front of the rotating shaft 12, and the grinding wheel 13 is located inside the four sets of limit plates 6.

[0032] When the motor 11 is running, the rotating shaft 12 can drive the grinding wheel 13 to rotate inside the four sets of limit plates 6. By continuously adjusting the use position of the grinding wheel 13, the grinding wheel 13 can be used to grind the clamped guardrail.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution: an assembled highway guardrail burr grinding device;

[0034] A collecting shell 15 is arranged on the top of the supporting frame 1, a guide shell 16 is arranged on the top of the collecting shell 15, and the guide shell 16 is located below the grinding wheel 13, an exhaust tube 17 is arranged inside the supporting frame 1, an exhaust fan 18 is arranged inside the exhaust tube 17, an air supply pipe 19 is arranged on the front of the exhaust tube 17, and the air supply pipe 19 movably passes through the inner wall of the collecting shell 15, and a blocking net 20 is arranged inside the air supply pipe 19.

[0035] The exhaust tube 17 provides installation space and protection for the exhaust fan 18. After the exhaust fan 18 is running, external air can enter the exhaust tube 17 through the air duct 19. The air duct 19 penetrates the inner wall of the collecting shell 15 by movement, and the air inside the collecting shell 15 can enter the exhaust tube 17 through the air duct 19. The blocking net 20 arranged inside the air duct 19 can effectively block the grinding debris to prevent the grinding debris collected inside the collecting shell 15 from entering the air duct 19. The guide shell 16 is located below the grinding wheel 13, and the debris generated by the grinding wheel 13 grinding the guardrail can fall into the collecting shell 15 for temporary collection and storage, which is not only convenient for cleaning the debris generated by grinding, but also convenient for subsequent centralized processing of the grinding debris.

[0036] Working principle: by moving the use position of the support frame 1, the guardrail that needs to be polished is located inside the four groups of limit plates 6. The four groups of limit plates 6 are not completely combined into a circular ring shape, which is convenient for adapting to guardrails of different shapes that need to be polished. By applying a rotating force to the threaded rod 7 threadedly connected inside each limit plate 6, the threaded rod 7 can push the extrusion pad 8 set at the other end to extrude and position the guardrails of different shapes set inside the four groups of limit plates 6. The extrusion pad 8 is an anti-slip rubber pad. The extrusion pad 8 can increase the friction of the guardrail to avoid shaking of the guardrail in the clamping and polishing state. By applying a pushing force to the No. 2 push rod 14, the movement of the sliding frame 9 can cause the spring 10 to deform, thereby adjusting the use position of the grinding wheel 13. By adopting a method of clamping and fastening the guardrail to fix the grinding device at one end of the guardrail, it can not only save the physical output of the staff, but also effectively avoid the occurrence of situations such as the grinding equipment falling off, thereby improving the safety of the grinding equipment when in use.

[0037] When the exhaust fan 18 is running, external air can enter the exhaust tube 17 through the air duct 19, accelerating the speed at which external air enters the collecting shell 15, so that the debris generated by the grinding wheel 13 grinding the guardrail can enter the collecting shell 15. The blocking net 20 arranged inside the air duct 19 can effectively block the grinding debris, preventing the grinding debris collected in the collecting shell 15 from entering the air duct 19. Since the guide shell 16 is located below the grinding wheel 13, the debris generated by the grinding wheel 13 grinding the guardrail can fall into the collecting shell 15 for temporary collection and storage, which is not only convenient for cleaning the debris generated by grinding, but also convenient for subsequent centralized processing of the grinding debris.
