Specific implementation manners

[0019] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0020] The first embodiment of this application is as follows:

[0021] Please refer to Figures 1 - 3 , wherein Figure 1 is the overall structural schematic diagram of the first embodiment of the present invention; Figure 2 is the structural schematic diagram inside the mounting bracket of the first embodiment of the present invention; Figure 3 Yes Figure 2 It is an enlarged view of part A in the figure.

[0022] The present invention provides a guardrail renovation and polishing device, which includes a vehicle body 101, a U-shaped frame 102, a sector sprinkler 103 and a polishing mechanism. The polishing mechanism includes a mounting bracket 104, a driving assembly, a moving seat 105 and a grinding wheel 106. The driving assembly includes a motor box 107, a driving motor 108, a driving gear 109, a driving shaft 110, a driving rod 111, a limiting shaft 1 112 and a limiting shaft 2 113. Through the foregoing solution, the problems that the prior art cannot polish the guardrail to enhance the anti-corrosion property, directly spray the guardrail, which will cause the surface of the guardrail to be uneven, and the inside of the guardrail will be corroded after some paint peels off are solved.

[0023] For this specific embodiment, the U-shaped frame 102 is fixedly connected above the vehicle body 101, the sector-shaped nozzle 103 is fixedly arranged in the U-shaped frame 102, the mounting frame 104 is fixedly connected to one side of the U-shaped frame 102, the driving assembly is located in the mounting frame 104, the moving seat 105 is slidably connected to the surface of the mounting frame 104, and the grinding wheel 106 is fixedly connected to one side of the moving seat 105. When polishing the guardrail, according to the shape of the guardrail, select the corresponding polishing grinding wheel, start the driving assembly and the grinding wheel 106, the moving seat 105 drives the grinding wheel 106 to move, and at the same time the grinding wheel 106 grinds and polishes the guardrail, making the surface of the guardrail flat and enhancing the anti-corrosion property of the guardrail. Subsequently, the guardrail is spray-painted and protected by the sector-shaped nozzle 103, further enhancing the anti-corrosion property of the guardrail. Because the surface of the guardrail after grinding and polishing is flat, the paint surface is more beautiful.

[0024] Among them, the motor box 107 is slidably connected in the mounting frame 104 and is provided with two auxiliary shafts 114. The driving motor 108 is fixedly connected in the motor box 107. The motor box 107 is used to mount the driving motor 108, and the driving motor 108 is used to provide the power for the movement of the grinding wheel 106. The two auxiliary shafts 114 enable the motor box 107 to move along a fixed track during movement and when the driving motor 108 is started, the output end rotates, rather than the motor box 107 rotating.

[0025] Secondly, a mating rack 115 is provided in the mounting frame 104. The driving gear 109 is fixedly connected to the output end of the driving motor 108 and meshes with the mating rack 115. The driving shaft 110 is fixedly connected to one side of the driving gear 109. The driving rod 111 is slidably connected to the mounting frame 104 and sleeved on the surface of the driving shaft 110, and one end of the driving rod 111 is fixedly connected to the moving seat 105. When the driving motor 108 is started, the driving gear 109 rotates. Because it meshes with the mating rack 115, it starts to move along the fixed rack. Under the action of the driving shaft 110 and the two auxiliary shafts 114, the driving rod 111 and the motor box 107 are driven to move.

[0026] Meanwhile, the limiting shaft one 112 is slidably connected to the mounting bracket 104 and fixedly connected to one end of the driving rod 111. The limiting shaft two 113 is slidably connected to the mounting bracket 104, fixedly connected to the driving rod 111, and located at the end far from the limiting shaft one 112. The limiting shaft one 112 and the limiting shaft two 113 are respectively coaxial with the two auxiliary shafts 114. When the driving shaft 110 moves with the driving gear 109, the driving rod 111 can only move along the same trajectory as the driving gear 109 under the action of the limiting rod one and the limiting rod two.

[0027] When polishing the guardrail, select the corresponding polishing grinding wheel according to the shape of the guardrail, and start the driving motor 108 and the grinding machine 106. The driving motor 108 starts to rotate. On the two auxiliary shafts 114, the driving gear 109 rotates. Because it meshes with the mating rack 115, it drives the motor box 107 and the driving shaft 110 to move along the mating rack 115. Under the action of the driving shaft 110, the limiting rod one and the limiting rod two, the driving rod 111 moves with the driving gear 109. Under the action of the limiting shaft one 112, the limiting shaft two 113 and the two auxiliary shafts 114, the moving seat 105 moves along the same trajectory as the driving gear 109, driving the grinding machine 106 to move. At the same time, the grinding machine 106 grinds and polishes the guardrail, making the surface of the guardrail flat and enhancing the anti-corrosion property of the guardrail. Subsequently, the guardrail is spray-painted and protected by the sector-shaped spray head 103, further enhancing the anti-corrosion property of the guardrail. Because the surface of the guardrail after grinding and polishing is flat, the paint surface is more beautiful, avoiding the problem in the prior art that the guardrail cannot be ground to enhance the anti-corrosion property, and directly spraying the guardrail will cause the surface of the guardrail to be uneven, and after some paint surfaces fall off, the inside of the guardrail is corroded, and the effect of polishing the guardrail and enhancing the anti-corrosion property of the guardrail is obtained.

[0028] The second embodiment of this application is:

[0029] Please refer to Figures 4 - 5 , in which Figure 4 is the overall structural schematic diagram of the second embodiment of the present utility model; Figure 5 is Figure 4 the enlarged view of part B in

[0030] On the basis of the first embodiment, the "guardrail renovation and polishing device" of this embodiment further includes a telescopic mechanism, and the telescopic mechanism includes a mounting box 201 and a hydraulic cylinder 202.

[0031] Among them, the installation box 201 is fixedly connected to one side of the moving seat 105, the hydraulic cylinder 202 is fixedly connected inside the installation box 201, and the output end is fixedly connected to the grinding wheel 106. During polishing, some positions of the guardrail are in a sunken state. At this time, start the hydraulic cylinder 202 to eject the grinding wheel 106 by an appropriate distance, so that the grinding wheel 106 can polish the sunken part of the guardrail, achieving the effect of reducing polishing omissions.
