Technical Field

[0001] The invention relates to an integral frame of a milling machine, belonging to the technical field of engineering machinery. Background Art

[0002] Milling machines are specialized equipment for highway and urban road maintenance. Large milling machines with a milling width greater than 2 meters can efficiently and quickly complete the excavation and renovation of asphalt concrete on highways, urban roads, airports, etc.

[0003] The frame of a large milling machine is a rigid structure welded from thick steel plates. It has sufficient rigidity and strength to not only carry various components, but also requires the frame to have sufficient mass to reduce the vibration of the whole machine during operation. The existing large milling machine frames mainly have the following problems:

[0004] The existing milling machine frame is closed by connecting the side plates on both sides by thick plate welding, and the fuel tank is installed on the frame by fasteners. In order to achieve better rigidity and strength, the welded thick plates occupy a large space, making the overall size of the frame larger;

[0005] The side panels of the existing milling machine frame are flush, and the side walls of the milling chamber are flush with the frame side panels; since the frame side panels block the line of sight, it is difficult for the driver to observe the milling edge line;

[0006] The above problems affect the flexibility and maneuverability of the entire vehicle, reduce construction efficiency, and affect the performance of the entire vehicle. Summary of the invention

[0007] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an integral frame for a milling machine, thereby reducing the overall size of the frame while ensuring good rigidity and strength and improving the observability of the milling edge line.

[0008] To achieve the above object, the present invention adopts the following technical solution:

[0009] A milling machine integral frame comprises a water tank, front legs welded on both sides of the water tank, outer plates of the water tank welded on the outer sides of the front legs, middle side plates welded to the outer plates of the water tank, a fuel tank arranged between the two middle side plates, rear legs arranged behind the fuel tank and welded to the middle side plates through the rear side plates, and a milling unit mounting seat connected to the milling unit arranged below the fuel tank, an operating table is installed above the fuel tank, supporting devices are respectively connected below the front legs and the rear legs, and the middle side plates are inclined inwards from top to bottom.

[0010] Furthermore, the milling unit mounting seat is welded below the outer side of the fuel tank, and the outer wall of the milling unit installed below exceeds the outer wall of the middle side plate.

[0011] Furthermore, the overlapping portion between the rear side plate and the middle side plate is bent inwards.

[0012] Furthermore, the milling unit is installed in the visible space of the operating table, and the supporting device under the front legs is installed in the visible space of the operating table.

[0013] Furthermore, the fuel tank is connected to the middle side plate by welding and is closed by welding to the water tank.

[0014] Furthermore, pipelines and vacuum pipelines are provided inside the water tank.

[0015] Furthermore, a tensioning rocker arm connecting plate is welded to the outer side of the rear side plate, and a plurality of connecting inner holes are provided on the connecting plate.

[0016] Furthermore, a plurality of milling unit mounting seats are provided on both sides of the fuel tank, and at least one milling unit mounting seat on each side is welded to the middle side plate.

[0017] The technical solution is welded between multiple parts, which reduces the number of fasteners, ensures the overall rigidity, strength and connection reliability, and reduces the mass and space occupied by the overall frame, making the vehicle more flexible and maneuverable, and the construction efficiency is higher;

[0018] The middle side plate and the rear side plate of the technical solution are both inclined inwards and the two sides of the milling unit mounting seat extend beyond the middle side plate, which can increase the visual space range of the operator at the operating table and facilitate observation of the working status of the supporting device and the milling unit;

[0019] The technical solution is provided with brake pipes and vacuum pipes, which are convenient for connecting and storing hydraulic, electrical and other line pipes, and the vacuum pipes can be convenient for vacuum dust removal, thereby improving the control utilization rate of the water tank;

Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0029] A milling machine integral frame as described in the attached drawings comprises a water tank 1, front legs 2 welded on both sides of the water tank, outer side plates 3 of the water tank welded on the outer sides of the front legs, a middle side plate 4 welded to the outer side plates of the water tank, a fuel tank 5 arranged between the two middle side plates, a rear leg 7 arranged at the rear of the fuel tank and welded to the middle side plate through a rear side plate 6, a milling unit mounting seat 9 arranged below the fuel tank and connected to a milling unit 10, an operating table 8 is installed above the fuel tank, support devices 11 are respectively connected below the front legs and the rear legs, and the middle side plate is inclined inward from top to bottom;

[0030] The various parts are connected by welding through the middle side plates, which reduces the use of fasteners, ensures the connection strength of the frame while reducing the frame mass and occupied space. The inward tilt of the middle side plates can expand the visual space of the operator in the operating table, making it easier to observe the working status of various parts of the milling machine; the supporting device is a crawler track or a support wheel.

[0031] Furthermore, the milling unit mounting seat is welded below the outer side of the fuel tank and the outer wall of the milling unit mounted below exceeds the outer wall of the middle side plate;

[0032] The protruding setting of the milling unit can make it more convenient for the operator at the operating table to observe the working status of the milling unit, and the visibility is better.

[0033] In one embodiment, the overlap between the rear side plate 6 and the middle side plate 4 is bent inwards;

[0034] Inward bending and overlapping can reduce the molding volume, enhance the structural strength, increase the visual range of the operator at the operating table, make observation more convenient, and make construction safer.

[0035] Further, the milling unit is installed in the visible space of the operating table, and the supporting device under the front legs is installed in the visible space of the operating table;

[0036] The middle side panel is tilted inward, and the rear side panel and its overlap are bent inward, forming a prism-like visual space together with the outer side panel of the water tank; the working and supporting transmission devices are installed in the visual space to facilitate operators to observe at all times, understand and adjust the operating status of the equipment in time, which is convenient for use.

[0037] Furthermore, the fuel tank is welded to the middle side plate and is welded to the water tank;

[0038] After the fuel tank and the water tank are welded together to form a closed connection, the outside is then welded together with the middle side panels to ensure the connection strength at all locations, reduce gaps to make the connection more substantial, and avoid damage to the overall structure caused by vibrations caused by gaps.

[0039] In one embodiment, a pipeline 12 and a vacuum pipeline 13 are provided inside the water tank;

[0040] The pipeline is composed of steel pipes, and the vacuum pipe is composed of steel pipes and the side panels of the water tank. The pipeline is used to store and organize the hydraulic and electrical pipelines, making the lines more tidy, reducing space occupancy, and facilitating line arrangement. The vacuum pipe is used for vacuum dust removal devices. This arrangement improves the utilization rate of the water tank's controls and improves the integrity of the structure.

[0041] In one embodiment, a tensioning rocker arm connecting plate 14 is welded to the outer side of the rear side plate, and a plurality of connecting inner holes are provided on the connecting plate;

[0042] The tensioning rocker arm connecting plate is used to connect the transmission power device. Welding it on the rear side panel can reduce space occupancy and ensure structural strength and working stability.

[0043] Furthermore, a plurality of milling unit mounting seats are provided on both sides of the fuel tank, and at least one milling unit mounting seat on each side is welded to the middle side plate;

[0044] Multiple milling unit mounting seats can make the structure more evenly stressed. Installing the milling unit mounting seats on the same side on different components can enhance the connection strength of the structure, make each part evenly stressed, and improve working stability.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
