Technical Field
[0001] This utility model relates to the field of milling device technology, specifically a milling device for road side milling. Background Technology
[0002] When constructing or maintaining roads, a type of engineering machinery is usually used to mill the uneven parts of the roadside, making the road edges smooth, improving the quality and safety of the road, thereby reducing the bumps when vehicles are driving and extending the service life of the road surface.
[0003] When performing side milling on roads, existing milling devices are based on vehicles, with support frames installed on the sides of the vehicles. Milling equipment is fixedly mounted on the sides of the support frames with bolts. Milling cutters are installed inside the milling equipment. The milling equipment uses its inner milling cutters to mill the road side. At the same time, the vehicle moves, and with the cooperation of the support frames, the milling equipment can mill the road side along the direction of the road for subsequent construction or maintenance.
[0004] However, during the current milling process, vehicles may bump due to uneven roads, causing the milling equipment to move vertically via the support frame. This results in uneven milling surfaces and reduces the service life of the road. Therefore, a milling device for road side milling is proposed. Utility Model Content
[0005] To address the shortcomings of existing technologies, in the process of milling equipment on the market, vehicles may bump due to uneven roads, causing the milling equipment to move vertically via the support frame, resulting in uneven milled surfaces and reduced road lifespan. This utility model proposes a milling device for road side milling.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The milling device for road side milling described in this utility model includes a support platform; an adjustment mechanism is provided on the side of the support platform, a lifting mechanism is provided on the inner side of the support platform, a telescopic mechanism is provided on the back side of the support platform, and a bracket is provided on the side of the support platform.
[0007] Preferably, the adjustment mechanism includes a bracket, a support rod slidably inserted inside the bracket, a disc fixed to the bottom end of the support rod, a spring fixedly connected between the disc and the bracket, a roller fixedly installed at the bottom end of the disc, a limit plate fixed to the top side of the bracket, baffles symmetrically fixed to the sides of the limit plate, a controller fixed to the inside of the baffles, a push plate fixed to the side of the support rod, the push plate being located between the two controllers, a servo motor fixed to one end of the top side of the support platform, the controller being signal-connected to the servo motor, and cooperating with the support rod through the roller. If the road surface is uneven, the support rod slides up and down inside the bracket, thereby contacting the controller and controlling the servo motor to adjust the milling depth, thereby ensuring the flatness of the milled surface.
[0008] Preferably, the lifting mechanism includes a servo motor, the output end of which is fixed to a lead screw passing through a support platform. The lead screw is rotatably mounted on one end of the inner side of the support platform, and a slide rod is fixed to the other end of the inner side of the support platform. A lifting platform is slidably mounted on the slide rod, and the lifting platform is rotatably connected to the lead screw. A milling machine body is fixedly mounted on one side of the lifting platform, and a telescopic cylinder is fixed to the back of the support platform. By using the lead screw in conjunction with the lifting platform, the height of the milling machine body can be adjusted at any time to ensure that its milling position does not shift, thereby improving the processing quality of the equipment.
[0009] Preferably, the telescopic mechanism includes a telescopic cylinder, a sleeve is slidably fitted on the outer side of the telescopic cylinder, one end of the sleeve is fixedly installed on the vehicle body, an electric telescopic rod is fixedly installed on the side of the vehicle body, and the electric telescopic rod is located inside the telescopic cylinder and the sleeve. The output end of the electric telescopic rod is fixedly connected to the back side of the support platform. By using the electric telescopic rod in conjunction with the telescopic cylinder, the equipment can be applied to various road surfaces, making the equipment more widely applicable.
[0010] The advantages of this utility model are:
[0011] 1. This utility model relates to a milling device for road side milling. By setting an adjustment mechanism, the roller is located in the groove of the milled road surface, with the bottom of the inner groove in contact with the road surface. If the road surface is uneven, the spring pushes the disc to rise and fall through its own elasticity, so that the roller is in close contact with the milled road surface. This causes the support rod to move telescopically relative to the bracket. At this time, the support rod drives the push plate to contact the controller on one side, thereby controlling the servo motor to operate through the signal, adjusting the processing position of the milling equipment to be on the same horizontal plane as the roller, ensuring the flatness of the milling processing position, and solving the problem of inconvenience in the operation of the device due to uneven road surface.
[0012] 2. This utility model, through the structural design of a milling device for road side milling, sets up a lifting mechanism and controls a servo motor to drive the output screw to rotate, thereby driving the lifting platform to rise and slide on the slide rod inside the support platform, so as to drive the milling equipment body on the side of the lifting platform to rise and fall to a suitable position, thereby facilitating subsequent milling processing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0021] Please see Figure 1-4As shown, a milling device for road side milling includes a support platform 1; the support platform 1 is provided with an adjustment mechanism on its side, a lifting mechanism on its inner side, a telescopic mechanism on its back side, and a bracket 2 on its side.
[0022] Please see Figure 2 As shown, the adjustment mechanism includes a bracket 2, a support rod 3 slidingly inserted into the inner side of the bracket 2, a disc 4 fixed to the bottom end of the support rod 3, a spring 5 fixedly connected between the disc 4 and the bracket 2, a roller 6 fixedly installed at the bottom end of the disc 4, a limit plate 7 fixed to the top side of the bracket 2, baffles 8 symmetrically fixed to the sides of the limit plate 7, a controller 9 fixed to the inner side of the baffles 8, a push plate 10 fixed to the side of the support rod 3, the push plate 10 being located between the two controllers 9, a servo motor 13 fixed to one end of the top side of the support platform 1, and the controller 9 being signal-connected to the servo motor 13; operation When encountering problems where existing milling equipment is inconvenient to operate due to uneven road surfaces, the structure of the adjustment mechanism is adjusted so that the roller 6 is located in the groove milled on the road surface, with the bottom of its inner groove in contact with the road surface. If the road surface is uneven, the spring 5 pushes the disc 4 up and down through its own elasticity, so that the roller 6 is in close contact with the milled road surface, thereby causing the support rod 3 to move telescopically relative to the bracket 2. At this time, the support rod 3 drives the push plate 10 to contact the controller 9 on one side, thereby controlling the servo motor 13 to run through the signal, adjusting the processing position of the milling equipment to be on the same horizontal plane as the roller 6, ensuring the flatness of the milling processing position.
[0023] Please see Figure 3 As shown, the lifting mechanism includes a servo motor 13. The output end of the servo motor 13 passes through the support platform 1 and is fixed with a lead screw 14. The lead screw 14 is rotatably mounted on one end of the support platform 1. The other end of the support platform 1 is fixed with a slide rod 15. A lifting platform 11 is slidably mounted on the slide rod 15. The lifting platform 11 is rotatably connected to the lead screw 14. A milling machine body 12 is fixedly mounted on one side of the lifting platform 11. A telescopic cylinder 16 is fixed on the back side of the support platform 1. During operation, when encountering problems such as inconvenience caused by uneven road surfaces, the structure of the lifting mechanism controls the servo motor 13 to drive the lead screw 14 at the output end to rotate, thereby causing the lifting platform 11 to slide up and down on the slide rod 15 inside the support platform 1. This causes the milling machine body 12 on the side of the lifting platform 11 to rise and fall to a suitable position, thus facilitating subsequent milling processing.
[0024] Please see Figure 4As shown, the telescopic mechanism includes a telescopic cylinder 16, with a sleeve 17 slidably fitted on the outer side of the telescopic cylinder 16. One end of the sleeve 17 is fixedly mounted on the vehicle body 18, and an electric telescopic rod 19 is fixedly mounted on the side of the vehicle body 18. The electric telescopic rod 19 is located inside the telescopic cylinder 16 and the sleeve 17, and the output end of the electric telescopic rod 19 is fixedly connected to the back side of the support platform 1. During operation, when existing milling devices are inconvenient for milling curved roads, the structure of the telescopic mechanism controls the electric telescopic rod 19 to extend or shorten it. This, in conjunction with the telescopic cylinder 16 and the sleeve 17, pushes the support platform 1 to move horizontally, thereby adjusting the position of the milling device according to the road conditions and making it more widely applicable.
[0025] Please see Figure 5 As shown, the support platform 1 is symmetrically provided with telescopic plates 20 on its side, and one end of the telescopic plates 20 is fixedly connected to the lifting platform 11. During operation, when encountering the problem of gravel and soil entering the inside of the equipment during milling and causing damage, the structure of the telescopic plates 20 can separate the inside of the support platform 1 from the outside, while not affecting the lifting and moving of the lifting platform 11, thus extending the working life of the equipment.
[0026] Working Principle: During road construction or maintenance, engineering machinery is typically used to mill uneven sections of the road surface, smoothing the edges and improving road quality and safety. This reduces vehicle bumps and extends road lifespan. However, in existing milling systems, vehicle bumps due to uneven road surfaces, causing the milling equipment to move vertically via the support frame, resulting in uneven milled surfaces and reduced road lifespan. To address this, an adjustment and lifting mechanism is implemented. The vehicle body 18 moves the support platform 1, allowing the milling equipment body 12 on its side to mill the road surface. During milling, the roller 6 is positioned within the milled grooves on the road surface, with the bottom of the inner groove in contact with the road surface. If the road surface is uneven, the spring 5 uses its own elasticity to push the disc 4 up or down. The roller 6 is brought into close contact with the milled road surface, causing the support rod 3 to extend and retract relative to the bracket 2. At this time, the support rod 3 drives the push plate 10 to contact the controller 9 on one side, thereby controlling the servo motor 13 to run through the signal, which drives the output screw 14 to rotate, thereby driving the lifting platform 11 to slide up and down on the slide rod 15 inside the support platform 1. This raises and lowers the milling equipment body 12 on the side of the lifting platform 11 to the same horizontal plane as the roller 6, thus preventing the road surface level difference from affecting the road side milling process. During the processing, the electric telescopic rod 19 can be controlled according to the road curvature to extend or shorten it. With the cooperation of the telescopic cylinder 16 and the sleeve 17, the support platform 1 is pushed to extend and retract in the horizontal direction, adjusting the milling device to a suitable position, improving the quality of the road side milling process, and solving the problem of inconvenience caused by the road surface level difference.
