DETAILED DESCRIPTION

[0032] The embodiments of the present application are described in detail below in conjunction with the drawings in the embodiments of the present application.

[0033] Please refer to Figure 1-Figure 5 , which is a schematic diagram of the overall structure of the multi-purpose milling equipment,

[0034] This embodiment provides a multi-purpose milling and grinding device, comprising:

[0035] The frame 1 has a limit plate 2 horizontally provided at its lower portion, and a mounting frame 3 extending from its rear end; the mounting frame 3 is higher than the limit plate 2 at least at one end close to the frame 1 to form a fulcrum;

[0036] The limit adjustment assembly 4 includes a rocker frame 41 and support pulleys 42 symmetrically arranged on both sides below the limit plate 2. The rocker frame 41 is arranged above the limit plate 2 and can abut against the fulcrum. One end of the rocker frame 41 is connected to the two support pulleys 42 on both sides via traction members 43. The other end of the rocker frame 41 is connected to the swing drive mechanism 5 installed on the mounting frame 3.

[0037] The milling and grinding assembly includes a power drive box 6 and at least one combined tool 7, and the power drive box 6 is arranged on the top of the frame 1; the combined tool 7 includes a grinding head 71 and a tool 72, one end of the grinding head 71 is transmission-connected to the output end of the power drive box 6, and the tool 72 is detachably clamped at the other end of the grinding head 71.

[0038] Next, a multi-purpose milling and grinding device according to this exemplary embodiment will be further described.

[0039] In some embodiments, reference Figure 1 、 Figure 2 and Figure 5The frame 1 includes two oppositely disposed fixing plates 11 and a mounting plate 12 disposed between the two fixing plates 11. The mounting plate 12 is bolted to the upper portion of the two fixing plates 11, leaving a certain space above for mounting the power drive box 6, which is mounted on the mounting plate 12. A limit plate 2 is horizontally disposed at the lower portion of the frame 1. The limit plate 2 is positioned below and parallel to the mounting plate 12, forming a space between the limit plate 2 and the mounting plate 12 for the rocker arm to swing up and down. A mounting frame 3 is extended from the rear end of the frame 1. The mounting frame 3 is higher than the limit plate 2 at least at one end near the frame 1, thereby forming a fulcrum for the rocker arm 41 to swing up and down. Support pulleys 42 are provided on both sides below the limit plate 2. One end of the rocker frame 41 is connected to the support pulleys 42 via traction members 43 on both sides, which are used to drive the support pulleys 42 to move up and down. The traction members 43 are movably inserted into the limit plate 2 for easy connection. At the same time, they can axially limit the movement of the support pulley 42 to prevent lateral displacement and errors in depth adjustment. Specifically, the traction members 43 are rods. The limit plate 2 is used to limit the support pulley 42 below it to limit the adjustment of the processing depth. The other end of the rocker frame 41 is connected to the swing drive mechanism 5, which is installed on the mounting frame 3 and is used to drive the rocker frame 41 to swing up and down.

[0040] As an example, Figure 5 The swing drive mechanism 5 can be composed of a telescopic cylinder and a drive shaft. The telescopic cylinder is hinged to the mounting frame 3, and the end of the rocker frame 41 is hinged to the mounting frame 3. The telescopic end of the telescopic cylinder is connected to the rocker frame 41 via a transversely arranged drive shaft. The telescopic cylinder's extension and contraction drive the rocker frame 41 through the drive shaft to rotate about the hinge point, causing the other end to swing. Alternatively, a telescopic motor and drive shaft can be used, with adjustable stroke for easier control.

[0041] In some embodiments, the milling and grinding assembly includes a power drive box 6 and at least one modular tool 7. Specifically, the power drive box 6 can be a gear box, which can form a structure with one input end and multiple output ends through the meshing transmission of multiple gears (existing technology, which will not be described in detail). In this way, multiple modular tools 7 can be provided. When multiple modular tools 7 are provided, they are evenly arranged in the horizontal and vertical directions, which can increase the road processing area and improve efficiency.

[0042] Reference Figure 2 and Figure 3The above-mentioned combined tool 7 includes a grinding head 71 and a cutting tool 72. One end of the grinding head 71 is connected to the output end of the power drive box 6, and is driven by the power drive box 6 to rotate, thereby performing grinding, milling and other tasks. The above-mentioned cutting tool 72 is detachably clamped at the other end of the grinding head 71. The detachable clamping structure makes the cutting tool 72 replaceable and removable. The cutting tool 72 can be a cylindrical drill bit, a cutting knife, etc., so that different cutting tools 72 can be used to perform different processing on the road. For example, the drill bit can be used for drilling and grooving; the grinding head 71 can also be directly removed and used alone for milling. This makes the device have multiple functions and can be used for different purposes.

[0043] Specifically, when performing milling and grinding operations, one end of the rocker frame 41 can be driven down a certain distance, so that the other end of the rocker frame 41 drives the support pulley 42 up a certain distance, so that the grinding depth of the grinding head 71 can reach the distance of the up and down movement, thereby making the grinding depth adjustable and controllable.

[0044] As a preferred embodiment, the fixing plate 11 is provided with a sliding hole 111 along its height. Sliders 13 are respectively inserted into and locked into the sliding holes 111 on either side of the limiting plate 2. The sliding members 13 may be bolts, which, after passing through the sliding holes 111, are locked at both ends by nuts 713. The provision of the sliding holes 111 allows the vertical height of the limiting plate 2 to be adjusted, thereby further adjusting the processing depth.

[0045] Specifically, the height position of the limit plate 2 on the fixed plate 11 can be adjusted according to actual processing requirements, thereby adjusting the up and down movement height of the support pulley 42 to increase the adjustment range of the processing depth.

[0046] As a preferred embodiment, refer to Figure 2 The output end of the power drive box 6 faces the limit plate 2 and is connected to the grinding head 71 via a connecting shaft 61 that passes through the mounting plate 12 and the limit plate 2 in sequence. The connecting shaft 61 is slidably connected to the mounting plate 12 via a sliding sleeve 62. The connecting shaft 61 rotatably passes through the sliding sleeve 62 and is connected to the limit plate 2 via a bearing. The sliding sleeve 62 allows the connecting shaft 61 and the mounting plate 12 to slide relative to each other, thereby ensuring that the connecting shaft 61 and the mounting plate 12 do not interfere with each other when the limit plate 2 is adjusted up and down on the fixed plate 11.

[0047] As a preferred embodiment, refer to Figure 3The grinding head 71 includes a tool handle 711, a collet 712, a nut 713 and a grinding sheet 714. One end of the tool handle 711 is connected to the connecting shaft 61, and the collet 712 is inserted into the other end of the tool handle 711; the nut 713 is threadedly sleeved on the outside of the tool handle 711 and covered on the outside of the collet 712, and the grinding sheet 714 is connected to the end of the nut 713; the grinding head 71 is detachably clamped in the collet 712. It can be understood that the fixture composed of the tool handle 711, collet 712, nut 713 and other structures has the same structure and principle as the existing milling cutter fixture. The embodiment of the present application connects the grinding sheet 714 to the end of the nut 713 as a whole, so that the tool 72 can be rotated, clamped and released, and independent grinding can be achieved, thereby improving the functionality of the equipment.

[0048] The above-mentioned tool 72 can be a dovetail drill, which can form a dovetail groove in the concrete, thereby forming a mortise and tenon connection structure with the newly paved concrete, so as to improve the connection stability between the newly poured concrete and the old concrete, and reduce phenomena such as peeling, hollowing, and cracking.

[0049] As a preferred embodiment, refer to Figure 1 and Figure 4 A plurality of elastic support columns 8 are disposed between the limiting plate 2 and the mounting plate 12. These columns are positioned near the fixed plates 11 on either side. A telescopic portion 81 is disposed at each end of the elastic support column 8. The top telescopic portion 81 is fixedly connected to the mounting plate 12, while the bottom telescopic portion 81 passes through the limiting plate 2 and connects to the support pulley 42. By disposing the elastic support columns 8 between the limiting plate 2 and the mounting plate 12 and providing the telescopic portions 81 at both ends, each connected to the support pulley 42, the elastic support columns 8 can support the mounting plate 12 while also cushioning the upward and downward movement of the support pulley 42, thereby improving adjustment stability.

[0050] Specifically, there are four elastic telescopic columns, which are arranged in pairs on both sides close to the fixed plate 11. They include a column body and a compression spring 82 sleeved on the outside of the column body. The two ends of the compression spring 82 are respectively in contact with the mounting plate 12 and the limit plate 2.

[0051] As a preferred embodiment, the above-mentioned mounting frame 3 is a rectangular frame structure and is horizontally connected to the rear end of the frame 1. Its overall height is higher than the limit plate 2 and lower than the rocker frame 41, so that the middle rear part of the rocker frame 41 can be supported on the crossbeam of the mounting frame 3, which facilitates the support and stability of the rocker frame 41 after it moves upward.

[0052] As a preferred embodiment, refer to Figure 5The rocker frame 41 comprises a crossbar 411 and U-shaped bars 412 connected at both ends of the crossbar 411. A connecting rod extends between the openings of the two U-shaped bars 412. A traction member 43 is movably mounted on the limit plate 2, with one end connected to the connecting rod and the other end connected to the support pulley 42. This structure allows one of the elastic support columns 8 to pass through the opening of the U-shaped bar 412, improving the compactness and stability of the structure and allowing more space in the middle of the limit plate 2 to accommodate the combined tool 7.

[0053] As a preferred embodiment, movable pulleys 9 are spaced apart on both sides of the mounting frame 3 opposite to the two fixing plates 11 to facilitate the movement of the equipment and support of the mounting frame 3. The mounting frame 3 can also be used to install related equipment for road maintenance, such as cooling equipment.
